perf(ci): pytest-xdist with per-worker DBs — 22m → ~4m

Backend suite is the slow gate (1076 passed locally in 22m27s on
fix/ci-workflow-config). Adding pytest-xdist with per-worker DB
isolation drops it to ~4m20s on the 8-core homelab runner. Verified
locally: `pytest -n auto --no-cov` finished in 4m28s real time
(15m19s user — confirms ~5× parallelism).

How it works:
- conftest.py reads `PYTEST_XDIST_WORKER` (set per worker by xdist —
  'gw0', 'gw1', …). When set, derives a per-worker DB URL like
  `…/resolutionflow_test_gw0`. The base DB stays for serial / master
  runs.
- `_ensure_worker_db_exists` runs synchronously at conftest import,
  connects to the postgres maintenance DB, and `CREATE DATABASE`s the
  worker-suffixed DB if it doesn't exist. Idempotent across runs.
- The "test" safety guard still applies — every worker DB name
  contains "test" so the assertion holds.
- The per-test `DROP SCHEMA public CASCADE` now operates on the
  worker's isolated DB, no cross-worker race.

CI workflow: backend job switches to `pytest -n auto`. Coverage still
collected (pytest-cov has built-in xdist support).

Adds `pytest-xdist==3.6.1` to requirements-dev.txt.

+# CURRENT_TASK.md
+
+**Task:** Restore a fully green CI gate on `main` and lock it via branch protection so future merges can't introduce silent rot.
+
+**Status:** in-progress
+
+**Definition of Done:**
+- [ ] PR #150 (`fix/ci-workflow-config`) merged. Both `CI / backend (pull_request)` and `CI / frontend (pull_request)` show success on the merge commit.
+- [ ] `CI / backend (pull_request)` added to required status checks on `main` in Gitea branch protection (frontend is already required).
+- [ ] The 54 real backend test failures (left after #149's infra cleanup) categorized and fixed in a follow-up PR. Target: 0 failures, 0 errors on a `pytest` run inside `resolutionflow_backend`.
+- [ ] `npm run lint` stays at 0 errors after the cleanup PR (already at 0 on main).
+- [ ] Append a SESSION_LOG.md entry summarizing what shipped.
+
+**Assumptions:**
+- The 54 failures fall into a small number of root-cause categories (likely 3–5: fixture-scoping leaks, DB cleanup ordering, account_id propagation in test seed paths). Verify before assuming.
+- The pytest-asyncio 0.24 + pytest 8.4 toolchain bumped in #149 is the right baseline; do not revert.
+- `DATABASE_TEST_URL` is the only DB URL conftest will honor; do not weaken the safety guard added in `dab740d`.
+
+**Out of scope:**
+- New feature work on FlowPilot (Phase 10+) or PSA — keep this branch focused on CI debt.
+- Frontend lint warnings (23 remain after #149; they're missing-deps in useEffect, opt-in cleanup later).
+- RLS test suite (`test_rls_isolation.py`) — gated behind `RUN_RLS_TESTS=1` and not in the default CI run.

+## 2026-04-24 — Adopt dual-agent handoff system (`.ai/` + `CLAUDE.md` + `AGENTS.md`)
+
+**Context:** Claude Code hits session and weekly usage limits. Work stalls when the primary agent is locked out. Needed a structured way for OpenAI Codex to resume where Claude left off without losing architectural truth or drifting across sessions.
+
+**Decision:** Split the old CLAUDE.md into `.ai/PROJECT_CONTEXT.md` (stable repo truth), agent-specific root files (`CLAUDE.md`, `AGENTS.md`) with a shared protocol block, and a small handoff toolkit (`CURRENT_TASK.md`, `HANDOFF.md`, `TODO.md`, `DECISIONS.md`, `SESSION_LOG.md`, `README.md`). Previous CLAUDE.md snapshotted in commit `e110fed` before the migration.
+
+**Rejected:**
+- Single symlinked CLAUDE.md/AGENTS.md — diverges silently, hides agent-specific tooling differences.
+- Putting GitNexus/gstack content in AGENTS.md — Codex doesn't have those tools; would mislead the resume agent.
+- Keeping the old CLAUDE.md as-is and adding AGENTS.md alongside it — duplicated truth, drift guaranteed.
+
+**Consequences:**
+- First read for either agent: `.ai/PROJECT_CONTEXT.md` + `.ai/CURRENT_TASK.md` + `.ai/HANDOFF.md`.
+- Architectural changes in the repo require updating PROJECT_CONTEXT.md, not the root agent files.
+- Git trailers differ per agent (`Claude Opus 4.7` vs `Codex`) — preserved in each root file.
+- Legacy `SESSION-HANDOFF.md` deleted in the same commit; superseded by `.ai/HANDOFF.md`.

+## Current state
+
+Previous session fixed the 54 real backend failures left after #149. The default backend suite is now green locally:
+
+```bash
+docker exec resolutionflow_backend bash -lc 'pytest --override-ini="addopts=" -q > /tmp/full-backend.log 2>&1; code=$?; tail -n 160 /tmp/full-backend.log; exit $code'
+# 1076 passed, 35 deselected in 1347.41s (0:22:27)
+```
+
+Targeted validation also passed:
+
+- `tests/test_session_resolutions_api.py tests/test_session_sharing.py tests/test_session_suggested_fixes_api.py tests/test_survey.py tests/test_tenant_isolation_p0.py tests/test_tree_sharing.py tests/test_trees.py::TestTrees::test_delete_tree_cleans_up_folder_and_tag_assignments tests/test_uploads.py::test_delete_upload_forbidden_for_non_owner` → `73 passed`
+- PDF export tests → `3 passed`
+- Prompt/PSA/resolution/script-builder subset → `14 passed`
+- Admin/AI/branch subsets → `11 passed`
+
+## What changed
+
+Production fixes:
+
+- CI/backend dev image now installs WeasyPrint system libraries.
+- Public share-token and survey routes are mounted outside tenant auth; protected share management remains tenant-protected.
+- Folder creation now persists `UserFolder.account_id`.
+- Script Builder save-to-library now persists `ScriptTemplate.account_id`.
+- Resolution output generation eager-loads `AISession.steps` to avoid async lazy-load `MissingGreenlet`.
+- AI session model now declares the generated `search_vector` column already present in Alembic, so `create_all` test schemas match runtime migrations.
+- Direct account-role update now rejects `"owner"`; ownership changes must use the transfer path.
+- Assistant prompt marker examples no longer include a literal executable `create_spin_off_ticket` payload.
+
+Test/harness fixes:
+
+- Test seeds updated for tenant-scoped `account_id` columns on sessions, branches, resolution outputs, script templates, PSA connections, folders, schedules, and categories.
+- Tests aligned with 404-not-403 resource-hiding policy.
+- Disabled-AI tests now restore both Anthropic and Google key settings.
+- Pytest harness closes pytest-asyncio's leftover clean loop and ignores known unclosed asyncio/asyncpg teardown ResourceWarnings that otherwise appear at arbitrary later setup points under `filterwarnings = error`.
+
+## Immediate next steps
+
+1. Commit current working tree if not already committed with trailer:
+   `Co-Authored-By: Codex <noreply@openai.com>`.
+2. Check PR #150 status on Gitea. If both `CI / backend (pull_request)` and `CI / frontend (pull_request)` are green, merge it.
+3. After #150 merges, add `CI / backend (pull_request)` to required status checks on main:
+   ```bash
+   PATCH /repos/chihlasm/resolutionflow/branch_protections/main
+   { "status_check_contexts": ["CI / frontend (pull_request)", "CI / backend (pull_request)"] }
+   ```
+   `$GITEA_TOKEN` is in `.claude/settings.local.json`.
+4. Run/confirm frontend lint if needed for the final DoD item (`npm run lint` was already green after #149, but this session did not rerun it).
+
+## Open questions
+
+- PR #150 was not rechecked or merged in this session.
+- Branch protection was not updated in this session.

+# PROJECT_CONTEXT.md — ResolutionFlow
+
+> SaaS troubleshooting platform for MSPs. Stable architectural truth. Updated only when the repo's shape changes.
+
+---
+
+## Product & naming
+
+Canonical product name is **ResolutionFlow**. `patherly` is the legacy internal name — still present in DB name (`patherly` on Railway, `resolutionflow` locally), some Railway service names, and historical paths. Treat as aliases, not canonical. Docker containers are `resolutionflow_*`.
+
+**User terminology:** "Flows" (not Trees), "Projects" (not Procedures), "Solutions Library" (not Step Library). Maintenance flows hidden from pilot UI (backend retains them). DB column `tree_type` values unchanged.
+
+---
+
+## SaaS shape
+
+Multi-tenant by account. Primary role hierarchy: `super_admin` > `owner` > `engineer` > `viewer` — driven by `is_super_admin` + `account_role`. Never `role=='admin'` — use `is_super_admin`. Separate team-scoped admin gate exists orthogonally to the role hierarchy: `is_team_admin=True` + valid `team_id`, enforced by `require_team_admin`. Backend deps in `app/api/deps.py`: `get_current_active_user`, `require_engineer_or_admin`, `require_admin`, `require_account_owner`, `require_team_admin`. Frontend: `usePermissions()` hook. Central logic in `backend/app/core/permissions.py` + `frontend/src/hooks/usePermissions.ts`.
+
+---
+
+## Status
+
+Go-to-Market Validation (pre-PMF). Backend feature-complete (55+ endpoints, 100+ tests). Phase 0.5 FlowPilot telemetry baseline accruing. See [CURRENT-STATE.md](../CURRENT-STATE.md) for live status, [03-DEVELOPMENT-ROADMAP.md](../03-DEVELOPMENT-ROADMAP.md) for phases.
+
+---
+
+## Tech stack
+
+- **Backend:** Python 3.11 + FastAPI, SQLAlchemy 2.0 async (asyncpg), Alembic, Pydantic v2, JWT (python-jose + bcrypt, JTI refresh rotation), APScheduler (in-process with FastAPI lifespan).
+- **Frontend:** React 19 + Vite + TypeScript, Tailwind v4 (CSS-only config in `index.css`), Zustand (immer + zundo), React Router v7, Axios (token-refresh interceptor), Lucide.
+- **DB:** PostgreSQL 16 (RLS enabled Phase 4, pgvector).

+## Dev commands
+
+Full setup in [DEV-ENV.md](../DEV-ENV.md) (host-agnostic, with homelab Proxmox reference topology). Day-to-day:
+
+```bash
+docker compose -f docker-compose.dev.yml up -d                      # start stack
+cd backend && source venv/bin/activate && uvicorn app.main:app --reload
+cd frontend && npm run dev
+pytest --override-ini="addopts="                                    # tests (first time: CREATE DATABASE resolutionflow_test)
+cd backend && alembic upgrade head                                  # migrate
+cd backend && alembic revision -m "desc"                            # manual migration (preferred per Lesson 77)
+cd backend && alembic revision --autogenerate -m "desc"             # picks up drift; review carefully
+cd frontend && npm run build                                        # stricter than tsc --noEmit — final check
+cd frontend && npx tsc -b                                           # TS-only check when dist/ has EACCES
+docker exec -it resolutionflow_postgres psql -U postgres -d resolutionflow
+python -m scripts.seed_trees                                        # seed (from backend/)
+```
+
+**Never pass `--rev-id`** to alembic — let it generate the hex hash.
+
+---
+
+## URLs & test users
+
+**URLs:** Frontend <http://localhost:5173>, backend <http://localhost:8000>, API docs <http://localhost:8000/api/docs>.
+
+**Test users** (all password `TestPass123!`): `admin@resolutionflow.example.com` (super_admin), `teamadmin@resolutionflow.example.com`, `engineer@resolutionflow.example.com`, `pro@resolutionflow.example.com`.
+
+---
+
+## CI
+
+Gitea (`gitea.resolutionflow.com/chihlasm/resolutionflow/actions`). `gh` CLI works for issues/PRs on the GitHub mirror, but not CI runs.
+
+---
+
+## Deployment (Railway)
+
+- **Prod:** `resolutionflow.com` (frontend), `api.resolutionflow.com` (backend).
+- Auto-deploy: Gitea push → GitHub mirror → Railway follows GitHub `main`.
+- PR environments auto-created; need manual domain generation + `VITE_API_URL` with `https://` prefix.
+- `ALLOW_RAILWAY_ORIGINS=true` for `*.up.railway.app` CORS.
+- Shared Variables (Railway project-level) auto-propagate to PR envs — use for secrets like `ANTHROPIC_API_KEY`.
+- Super admin utility: `backend/make_superadmin_simple.py list|<email>`.
+
+---
+
+## ConnectWise PSA
+
+Reference: `docs/connectwise/` — start with `CONNECTWISE-API-REFERENCE.md`, then the `best-practices/` guides. Extracted OpenAPI spec in `connectwise-psa-resolutionflow-reference.json` (670 endpoints, v2025.16); full spec in `connectwise-psa-openapi-full.json`.
+
+- **Auth:** API Key (Base64 `companyId+publicKey:privateKey`) + `clientId` header every request. `clientId` is server-side (`CW_CLIENT_ID` in `config.py`) — identifies ResolutionFlow, not per-tenant. Per-connection: `company_id`, `public_key`, `private_key`, `server_url`.
+- **Architecture:** `services/psa/` provider pattern — `PSAProvider` base, `ConnectWiseProvider` impl, `PsaProviderRegistry` for multi-PSA dispatch. Credentials encrypted at rest via `services/psa/encryption.py` (Fernet). Per-team credentials, never per-user. Endpoints in `api/endpoints/integrations.py`. In-memory TTL cache in `services/psa/cache.py`.
+- **Integration flows:** session docs → ticket notes (`POST /service/tickets/{id}/notes`, markdown supported); ticket context → FlowPilot; callbacks via `/system/callbacks` with HMAC verification.
+- **API rules:** pin version via Accept header `application/vnd.connectwise.com+json; version=2025.16`. Paginate ≤1000/page. Dynamic base URL via `/login/companyinfo/{companyId}`. Request minimal permissions (MY, not ALL).
+
+---
+
+## Coding standards
+
+- **Python:** type hints everywhere, async/await for DB, Pydantic v2, `DateTime(timezone=True)` always.
+- **TypeScript:** interfaces for all data, `const` over `let`, functional components + hooks, shared logic in custom hooks.
+- **Git:** feature branch before committing (`git checkout -b feat/feature-name`). Commit format: `type: description` (feat/fix/refactor/docs/test/chore). Large features: commit per phase with `npm run build` validation. Push to Gitea — auto-mirrors to GitHub (`.gitea/workflows/mirror-to-github.yml`); never push GitHub directly. (Agent-specific `Co-Authored-By` trailers live in CLAUDE.md / AGENTS.md.)
+
+**After shipping:** update [CURRENT-STATE.md](../CURRENT-STATE.md) + [03-DEVELOPMENT-ROADMAP.md](../03-DEVELOPMENT-ROADMAP.md), `gh issue close #N` for resolved issues, add lessons only for non-obvious traps (otherwise let the code speak).
+
+---
+
+## Common tasks
+
+- **New endpoint:** `endpoints/` → `router.py` → `schemas/` → tests → frontend API client.
+- **New page:** `pages/` → route in `router.tsx` → nav in `AppLayout.tsx`.
+- **New public route:** top-level in `router.tsx` alongside `/login`, not inside `ProtectedRoute`.
+- **New frontend API module:** types in `types/` → export from `types/index.ts` → client in `api/` → export from `api/index.ts`.
+- **Schema change:** update model → `alembic revision -m "desc"` → review → `alembic upgrade head`.
+- **New `VITE_*` env var:** add as `ARG` + `ENV` in `frontend/Dockerfile` for Railway builds (Lesson 60 — Railway env vars are runtime-only, Vite bakes at build time).
+- **Account sub-page:** add route in `router.tsx` under `account` children + add link card in `AccountSettingsPage.tsx` — `AccountLayout` has NO sidebar nav.
+
+---
+
+## Design system
+
+**Source of truth: [DESIGN-SYSTEM.md](../DESIGN-SYSTEM.md).** Read before any visual change.
+
+- Flat high-contrast dark theme, Sentry/PostHog-inspired. **No** glass, backdrop blur, ambient orbs, gradient surfaces.
+- Accent **electric blue** (#60a5fa dark / #2563eb light) — ≤5% of UI, interactive elements only. Warning amber (#fbbf24), info cyan (#67e8f9), success green (#34d399), danger red (#f87171). Each with `-dim` at 10% opacity.
+- Backgrounds: `bg-sidebar` (#0e1016) → `bg-page` (#16181f) → `bg-card` (#1e2028) → `bg-elevated` (#2a2d38). Borders `border-default` / `border-hover`.
+- Text: `text-heading` → `text-primary` → `text-muted-foreground` → `text-muted`.
+- Fonts: IBM Plex Sans (body), Bricolage Grotesque (heading, 700 weight for logo), JetBrains Mono (code).
+- Logo: 30px gradient square (ember orange) + "ResolutionFlow" in Bricolage Grotesque. Assets in `brand-assets/`, `frontend/src/assets/brand/`, `frontend/public/icons/`.
+- Mockups: `docs/mockups/` (HTML).
+- **Deprecated — do not use:** glass-card, glass-stat, `bg-gradient-brand`, `backdrop-filter: blur()`, ambient orbs, purple gradients, ember orange as accent, cyan as accent (cyan is info only).
+
+---
+
+## Frontend patterns
+
+- **Component basics:** `cn()` from `@/lib/utils`, Lucide icons, `Modal.tsx` for modals (mobile-responsive `items-end sm:items-center` + `max-w-full sm:max-w-lg`).
+- **Types:** Create in `types/`, export from `types/index.ts`, `import type { T } from '@/types'`.
+- **Routing:** `getTreeNavigatePath()` / `getTreeEditorPath()` from `@/lib/routing`. Tree editor is `/trees/new`. All dashboard session clicks → `/pilot/:id` regardless of `session_type`.
+- **Lazy routes:** `lazyWithRetry` from `@/lib/lazyWithRetry.ts`, not `React.lazy` (auto-reload on stale chunks).
+- **Public pages:** raw `fetch()` with full URL, NOT `apiClient` (which requires auth tokens).
+- **Toast:** `toast.warning()` not `toast.warn()`. Import from `@/lib/toast` — methods: `success`, `error`, `warning`, `info`.
+- **Assistant chat:** uses local React `useState`, not Zustand. All three send paths (`handleSend`, `sendPrefill`, `handleResumeNew`) must call `setShowTaskLane(true)` when response has actions/questions.
+- **Chat backend wiring:** `aiSessionsApi.sendChatMessage` → `/ai-sessions/{id}/chat` → `unified_chat_service.py`. NOT `assistant_chat_service.py` (removed except retention settings).
+- **FlowPilot:** Actions live in page header (Resolve/Escalate/Share Update + overflow). `useBlocker` for active-session nav guard. "Pause & Leave" auto-pauses.
+- **AI markers:** `[QUESTIONS]`, `[ACTIONS]`, `[FORK]`, `[DELTA]...[/DELTA]` (editor), `[TREE_UPDATE]` (troubleshooting builder), `[STEPS_UPDATE]` (procedural builder), `[METADATA]`. Parsed in `unified_chat_service.py`; conversation history stores stripped `display_content`. If markers disappear: check system-prompt final reminder + per-user-message `[SYSTEM: ...]` injection in `_call_anthropic_cached()`.
+- **Image uploads:** paste/attach → Railway S3 via `uploadsApi.upload()` → resized by `storage_service.resize_image_for_vision()` (Pillow, 1568px max, PNG→JPEG) → base64 → Claude multimodal blocks. Max 3/msg. Images NOT stored in history.
+- **Async select-load-apply:** guard with a ref (pattern in `AssistantChatPage` `currentChatRef`). Update synchronously on every selection change; after every `await`, bail out if `ref.current !== thisId`.
+- **Editor-Embedded Flow Assist:** `EditorAIPanel` (320px side panel) + `useEditorAI`. Ghost nodes via `_suggestion: true`. Route actions via `settings.get_model_for_action()`.
+- **Script Builder:** `/script-builder`, chat-style. Backend `ScriptBuilderSession`, `script_builder_service.py`, endpoints `/scripts/builder/`. FlowPilot handoff via `action_type: "open_script_builder"` + `sessionStorage`.
+- **Intake form field schema:** `variable_name` + `field_type` (NOT `name` / `type`).
+- **Node field priority** (copilot, summaries): `title` → `question` → `description` → `content` → `label`.
+- **Procedural sessions auto-start** on page load (no intake/Start screen). Troubleshooting flows DO have a start screen.
+
+---
+
+## Critical lessons
+
+> Lessons 1-40 archived to [docs/LESSONS-ARCHIVE.md](../docs/LESSONS-ARCHIVE.md) — fixes baked into the codebase. **Grep the archive when an error message or symptom is unfamiliar, or after two failed attempts at resolving an issue.** Don't pre-load for routine work.
+
+### Backend / data
+
+- **APScheduler interval jobs always `max_instances=1`** — without it, overlapping runs reprocess records (TOCTOU).
+- **`get_db` rolls back on exception** — never remove the `await session.rollback()`, or one failed request poisons the connection with `InFailedSQLTransaction` cascading.
+- **Startup routines on tenant-isolated tables must use `_admin_session_factory()`, not `get_db()`.** Phase 4 RLS has no `app.current_account_id` set at startup. `get_service_account_id` is safe (reads cached `app.state`).
+- **Backfill migrations adding `account_id`:** grep ALL `ModelClass(` sites in service code to verify `account_id=` is passed. SQLAlchemy accepts `None` silently — Phase 4 RLS WITH CHECK surfaces the problem at runtime as `InsufficientPrivilegeError: new row violates row-level security policy`.
+- **`tree_shares.account_id = tree.account_id`**, never `current_user.account_id`. A super_admin sharing another tenant's tree must produce the share in the tree owner's tenant, or it becomes invisible post-RLS.
+- **Global tables (no `account_id`, never in RLS migrations):** `script_categories`, `platform_steps`, `template_trees`, `plan_feature_defaults`, `accounts`. Scan at class level — one `.py` file can hold multiple classes with different columns (e.g. `ScriptCategory` vs `ScriptTemplate`).
+- **`ai_sessions.status` is VARCHAR(30)** — fits `requesting_escalation` (23 chars). Migration `f0aad74ea51b` widened from 20.
+- **PostgreSQL `func.sum(case(...))` returns `Decimal` via asyncpg** — cast to `int()` before Pydantic `dict[str, Any]`.
+- **Enhancement / branch_addition proposals need `modified_flow_data` via "Edit & Publish"** — backend 400 on direct approve. Only `new_flow` supports direct approve.
+- **Adding email types:** static async method on `EmailService` in `core/email.py`. Fire-and-forget from endpoints (log errors, don't fail the request).
+
+### AI / FlowPilot
+
+- **Anthropic SDK `max_retries=1`** — default of 2 can take 3× the timeout.
+- **Model tier routing:** `settings.get_model_for_action(action_type)`. Always alias form (`claude-sonnet-4-6`).
+- **FlowPilot must ask GUI-vs-script before suggesting either** when both are viable — see `FLOWPILOT_SYSTEM_PROMPT` in `flowpilot_engine.py`.
+- **Telemetry events to grep:** `anthropic.cache` (prompt-cache hit/create), `mcp.turn` (per-turn MCP availability), `mcp.fallback` (MCP silent-retry fired).
+- **Don't put literal payloads in system prompts.** Bit us twice in one day: a worked `[QUESTIONS]` example with literal "Outlook + jsmith" content, and a full DNS troubleshooting tree, both caused Claude to recite that content on unrelated tickets — the symptom looked like task-lane state leaking across chats. The fix is structural: every output example in a system prompt uses `<placeholder>` syntax (`{"text": "<one short, specific question>"}`), never literal field values. Real-looking format examples live in few-shot messages (separate file, separate code path), not system prompts. Guardrail: `tests/test_prompt_anti_parrot.py` scans every `*_PROMPT`/`*_SCHEMA`/`*_PROTOCOL`/`*_FORMAT` constant in `app/services/` and `app/core/`; CI fails when a marker block contains a literal JSON value or when a known leaked token (jsmith, DC01, ADSync, Dnscache, etc.) appears anywhere in a prompt.
+
+### Frontend / UI
+
+- **Flex height chain:** every ancestor from `app-shell` grid to React Flow canvas needs `flex` + `flex-1` + `min-h-0` or `h-full`. Missing `flex` collapses to 0. Same rule for FlowPilot action bar and any tall scroller.
+- **React Flow CSS in Tailwind v4:** import in `index.css`, not component JS. Override dark theme via `--xy-*` CSS vars.
+- **`text-secondary` renders invisible on dark** — Tailwind v4 maps it to `--color-secondary` (a surface color). Use `text-muted-foreground` for readable secondary text. Avoid `text-muted` for body — labels only.
+- **`bg-accent` is electric blue — never for code/kbd.** Use `bg-white/[0.12] border border-white/[0.06]` for inline code, `bg-white/[0.08]` for kbd. Accent reserved for interactive elements.
+- **`landing.css` uses self-contained `--lp-*` vars** — never `var(--color-*)` theme tokens (they resolve incorrectly outside the app shell).
+- **Never `transition: all`** — list properties explicitly, or layout props animate and jank.
+- **Date range filter end dates:** `setHours(23, 59, 59, 999)` before sending, or the day's items are excluded. For string-based date inputs, append `T23:59:59.999Z`.
+- **TopBar search:** full bar `hidden sm:block`, icon button `sm:hidden` — both open CommandPalette.
+- **Hover pop-out cards:** scrim `pointer-events-none`, expanded card has its own click handler at `z-50`, dismiss via `onMouseLeave` on wrapper. Never put handlers on the scrim.
+- **`tsc -b` in Dockerfile is stricter than `tsc --noEmit`** — enforces `noUnusedLocals` / `noUnusedParameters` as hard errors. Check IDE yellow squiggles before pushing.
+- **Dashboard prefill auto-submits** via `useEffect` + `prefillHandledRef` guard — no double-enter.
+- **Global Axios 5xx interceptor fires before component `.catch()`** — fix optional-data endpoints at the source (return `[]` / `{}` on provider failure), not in the component.
+- **Playwright strict mode:** scope selectors to avoid sidebar/main ambiguity. Use `getByRole('heading', { name })` or `.animate-scale-in` locators, not bare `getByText()`.
+
+### Env / infra
+
+- **Node 20.19+ required** (Vite 7). `nvm use 20` or `PATH="$HOME/.nvm/versions/node/v20.19.0/bin:$PATH"`.
+- **Railway backend service is `patherly`, DB name `railway`.** Public Postgres proxy: `interchange.proxy.rlwy.net:45797`.
+- **Railway Object Storage bucket `resolutionflow-uploads`.** Env vars `STORAGE_*`. boto3 in `storage_service.py`. Dockerfile needs Pillow + `libjpeg-dev` / `zlib1g-dev`.
+- **PostHog:** `PostHogProvider` + `posthog.init()` in `main.tsx`. Helpers in `lib/analytics.ts`. Env: `VITE_PUBLIC_POSTHOG_KEY`, `VITE_PUBLIC_POSTHOG_HOST`. `identifyUser()` in `authStore.fetchUser()`, `resetAnalytics()` on logout.
+- **bun PATH on devserver01:** `BUN_INSTALL="$HOME/.bun"`, `PATH="$BUN_INSTALL/bin:$PATH"`. Playwright Chromium needs `libatk1.0-0 libatk-bridge2.0-0 libcups2 libxkbcommon0 libatspi2.0-0 libxcomposite1 libxdamage1 libxfixes3 libxrandr2 libgbm1 libasound2`.
+- **Full-stack change:** trace schema → endpoint → API client → hook → store → UI. Don't assume one end proves the other.
+- **Dev env** — see [DEV-ENV.md](../DEV-ENV.md) for current topology, `REPO_ROOT` requirement when compose runs inside a container, Vite `allowedHosts`, linuxserver.io `group_add` + custom-cont-init.d workaround, `docker compose up` no-op-on-unchanged-hash gotcha.

+# .ai/ — dual-agent handoff system
+
+ResolutionFlow uses two coding agents: **Claude Code** (primary) and **OpenAI Codex** (resume when Claude hits session or weekly limits). This directory holds the shared state that lets either agent start a session with full context.
+
+## Files
+
+| File | Holds | Written when | Read when |
+|---|---|---|---|
+| [PROJECT_CONTEXT.md](PROJECT_CONTEXT.md) | Stable repo truth: stack, structure, SaaS shape, ConnectWise, coding standards, frontend patterns, critical lessons | Only when the repo's shape changes | Every session start |
+| [CURRENT_TASK.md](CURRENT_TASK.md) | The single active task: goal, DoD, assumptions, out-of-scope | On task start; status updates during work | Every session start |
+| [HANDOFF.md](HANDOFF.md) | Exact resume point: branch, where you left off, next steps, blockers | On session end / context-window limit | Every session start (most important) |
+| [TODO.md](TODO.md) | Backlog of work NOT currently active | When deferring or queueing work | Only when `CURRENT_TASK.md` is `complete` |
+| [DECISIONS.md](DECISIONS.md) | Append-only architectural decision log | When an architectural choice is made | Skim top entries each session |
+| [SESSION_LOG.md](SESSION_LOG.md) | Append-only chronological history | On session end | Only when broader context is needed |
+
+Agent-specific tooling lives at the repo root:
+- [../CLAUDE.md](../CLAUDE.md) — Claude Code's tooling (GitNexus, gstack slash commands, Claude trailer)
+- [../AGENTS.md](../AGENTS.md) — OpenAI Codex's tooling (grep/rg fallbacks, Codex trailer)
+
+Both root files contain an **identical shared-protocol block**. If you edit one, edit the other.
+
+## The handoff ritual
+
+At session end (limit hit, task complete, or user stop): update `HANDOFF.md` to reflect the new resume point, update `CURRENT_TASK.md` status if it changed, append to `DECISIONS.md` if you made an architectural call, append a session entry to `SESSION_LOG.md`, and WIP-commit any dirty working tree with `wip(handoff): <one-line>` unless told otherwise. Don't push.
+
+## How to invoke a resume
+
+Tell the agent:
+
+> Read CLAUDE.md (or AGENTS.md) and follow its instructions.
+
+The agent will read its root file, which directs it to `.ai/PROJECT_CONTEXT.md`, `.ai/CURRENT_TASK.md`, and `.ai/HANDOFF.md` before doing anything else.
+
+## Recovery
+
+The previous monolithic CLAUDE.md is recoverable via:
+
+```bash
+git show pre-ai-handoff:CLAUDE.md
+```
+
+(Tag `pre-ai-handoff` on commit `e110fed` — the snapshot taken before this migration.)

+## 2026-04-25 06:12 EDT — Codex — Fix backend suite to green
+
+- Fixed the real backend failures left after the CI-infra cleanup: tenant-scoped seed drift, missing production `account_id` writes, public route mounting for survey/share links, Script Builder library saves, resolution output async loading, AI search schema metadata, disabled-AI fixture leakage, and prompt marker guardrails.
+- Added backend CI/dev system packages required by WeasyPrint PDF export.
+- Stabilized the pytest harness for pytest-asyncio/asyncpg teardown ResourceWarnings under `filterwarnings = error`.
+- Verified `pytest --override-ini="addopts=" -q` inside `resolutionflow_backend`: `1076 passed, 35 deselected in 1347.41s`.
+- Left for next session: commit/push if needed, check and merge PR #150 when Gitea CI is green, add backend CI as a required branch-protection check, and rerun frontend lint if final DoD requires it.
+- Files touched: `.gitea/workflows/ci.yml`, `backend/Dockerfile.dev`, `backend/app/api/endpoints/folders.py`, `backend/app/api/endpoints/script_builder.py`, `backend/app/api/endpoints/shares.py`, `backend/app/api/router.py`, `backend/app/models/ai_session.py`, `backend/app/schemas/user.py`, `backend/app/services/assistant_chat_service.py`, `backend/app/services/resolution_output_generator.py`, `backend/app/services/script_builder_service.py`, `backend/pytest.ini`, `backend/tests/conftest.py`, and focused backend tests.
+
+## 2026-04-25 02:00 America/New_York — Claude Code — Land FlowPilot + PSA, recover CI from 488 errors to ~4
+
+- Started session by completing pending FlowPilot Phase 9 QA: ran `/qa` against the seeded fixtures, found and fixed four latent layout/state bugs (`ResolutionNotePreview` off-screen, `TemplateMatchPanel` deadlock when TaskLane closed, `EscalateInterceptDialog` clipped above viewport, `seed_test_users.py` `cancel_at_period_end` NOT NULL crash). Added a new fixture seeder `backend/scripts/seed_phase9_qa_fixtures.py` that pre-bakes the four backend states the AI orchestrator needs to emit, so future QA can exercise all 7 conditional Phase 9 components without depending on stochastic AI behavior.
+- Discovered PR #141 (PSA ticket management) and `feat/flowpilot-migration` had 5 overlapping files but only 2 real conflicts (`CLAUDE.md`, `AssistantChatPage.tsx`). Conflicts were both additive — concatenated rather than chose-a-side.
+- Merged PSA first (PR #141), then merged FlowPilot (PR #147), each through Gitea API. `tsc -b` clean and visual smoke-test confirmed PSA's Tickets sidebar coexists with Phase 9 ProposalBanner.
+- Discovered main had been merging through a broken CI gate for several merges. Initially recommended "stop the line, fix CI before shipping." After scoping the actual rot (~50% of tests red, ~600 errors on a clean run), reversed the recommendation: ship the queue first because FlowPilot itself carried significant test-infra repairs that would be duplicated work on a fresh recovery branch.
+- PR #148: two surgical fixes to main (network_diagrams JSONB `server_default` triple-quote bug, deprecated session-scoped `event_loop` fixture in conftest). +78 passing / -114 errors.
+- PR #149: frontend lint `20 errors → 0`, `requirements-dev.txt` pytest pin bumped to satisfy `pytest-asyncio==0.24.0`'s `pytest>=8.2`, and a one-line `from app import models as _models` in conftest that registers all ~60 models with `Base.metadata` before `create_all`. The conftest fix collapsed 484 of the remaining 488 backend errors. `1018 passed / 4 errors / 54 failed` after.
+- Enabled Gitea branch protection on `main`: PR-only merges, `CI / frontend (pull_request)` required, force-push blocked, no review required.
+- Discovered CI on the merge commit STILL showed red despite local pytest being mostly green. Root cause: workflow only set `DATABASE_URL`, but conftest reads only `DATABASE_TEST_URL` (per `dab740d`'s safety hardening). 638 connection-refused errors on every fixture setup. Plus `actions/upload-artifact@v4` not supported by Gitea Actions. PR #150 fixes both.
+- Left for next session: merge PR #150 once CI confirms green, add `CI / backend (pull_request)` to required status checks, then root-cause and fix the 54 real backend test failures (one sample seen — `test_user` fixture leaking across calls causing duplicate-email violations).
+- Files touched (committed): `backend/scripts/seed_test_users.py`, `backend/scripts/seed_phase9_qa_fixtures.py` (new), `backend/app/models/network_diagram.py`, `backend/tests/conftest.py`, `backend/requirements-dev.txt`, `frontend/src/components/pilot/ResolutionNotePreview.tsx`, `frontend/src/components/pilot/EscalateInterceptDialog.tsx`, `frontend/src/components/pilot/ScriptBuilderTab.tsx`, `frontend/src/pages/AssistantChatPage.tsx`, `frontend/src/pages/FlowPilotSessionPage.tsx`, `frontend/src/pages/TicketsPage.tsx`, `frontend/src/hooks/useFlowPilotSession.ts`, `frontend/src/hooks/useMediaQuery.ts`, `frontend/src/components/dashboard/TicketQueue.tsx`, `frontend/src/components/network/nodes/DeviceNode.tsx`, `frontend/src/components/network/nodes/GroupNode.tsx`, `frontend/src/components/routing/AssistantSessionRedirect.tsx` (new), `frontend/src/router.tsx`, `.gitea/workflows/ci.yml`, `.claude/settings.json` (new), `.claude/hooks/check-gstack.sh` (new), `.gitignore`, `CLAUDE.md`, `.gstack/qa-reports/phase9-*/` (QA artifacts).
+- Net merges to main: PR #141 (PSA), PR #147 (FlowPilot), PR #148 (CI fixes part 1), PR #149 (CI fixes part 2). PR #150 still open at session end.
+
+## 2026-04-24 — Claude Code — Migrate to dual-agent handoff system
+
+- Split CLAUDE.md into `.ai/PROJECT_CONTEXT.md` + shared-protocol root files (`CLAUDE.md`, `AGENTS.md`).
+- Seeded `CURRENT_TASK.md`, `HANDOFF.md`, `TODO.md`, `DECISIONS.md`, `SESSION_LOG.md`, `README.md`.
+- Deleted legacy `SESSION-HANDOFF.md` (superseded).
+- Left for next session: first real feature task should replace the seed `CURRENT_TASK.md` and update `HANDOFF.md` with real resume state.
+- Files touched: `.ai/*.md` (created), `CLAUDE.md` (rewritten), `AGENTS.md` (created), `SESSION-HANDOFF.md` (deleted).
+- Follow-up (same day): Codex review pass flagged stale SaaS-role claim and incomplete file-listings carried over from the pre-migration CLAUDE.md. Verified against `backend/app/core/permissions.py`, `frontend/src/hooks/usePermissions.ts`, `backend/app/api/deps.py`, `backend/app/api/router.py`, and `backend/app/services/psa/`. Corrected PROJECT_CONTEXT.md role hierarchy (`super_admin > owner > engineer > viewer`, not `team_admin`), added `require_account_owner` / `require_team_admin` to deps list, replaced stale endpoint comment with a summary pointing at `api/router.py`, added `exceptions.py` + `ticket_context.py` to the PSA file list. Also replaced seed-example content in `CURRENT_TASK.md` and `TODO.md` with clearer empty-state sentinels.
+- Branch cleanup (same day): committed pending test-isolation work as `b14a16a chore(tests): gate RLS tests behind RUN_RLS_TESTS flag`, new Phase 9 review doc as `b3506b5 docs(pilot): phase 9 review issues`, and `.remember/` gitignore entry as `b3be1e0 chore: ignore .remember/ skill runtime state`. Deleted `docs/landing-handoff/` (prepared for external design work, not meant to live in the repo). Working tree clean; 3 cleanup commits unpushed.

+- [ ] **Parallelize backend pytest with pytest-xdist.** Currently the backend suite takes ~22 min wall-clock for `1076 passed, 35 deselected` (verified locally 2026-04-25). With `-n auto` on the homelab Gitea Actions runner, this should land in the 3–6 min range depending on core count. Blocker: `test_db` fixture in `backend/tests/conftest.py` does `DROP SCHEMA public CASCADE` per test, which two workers would race on. Standard fix: one database per worker, derived from `PYTEST_XDIST_WORKER` env var inside conftest. The runner has spare CPU, so prioritize once main is green and the 54-failure cleanup has landed.
+
+## Backlog
+
+- [ ] **Frontend lint warnings cleanup.** 23 `react-hooks/exhaustive-deps` warnings remain after PR #149 (mostly missing-deps in useEffect). Either fix them or audit them for known-safe ones and add eslint-disable comments. Not blocking CI today.
+- [ ] **Audit `filterwarnings` ignores added in `wip(handoff): restore backend suite to green`.** Codex added narrow `ResourceWarning` filters for unclosed socket/transport/event-loop noise from pytest-asyncio teardown. Worth periodically reviewing whether those are still needed (e.g. when bumping pytest-asyncio) — if a real warning appears in those forms it would be silenced.

+
+You are OpenAI Codex, the resume agent for ResolutionFlow. Claude Code is the primary coding agent; you step in when Claude hits session or weekly limits.
+
+The first thing to do every session: read [`.ai/PROJECT_CONTEXT.md`](.ai/PROJECT_CONTEXT.md), [`.ai/CURRENT_TASK.md`](.ai/CURRENT_TASK.md), and [`.ai/HANDOFF.md`](.ai/HANDOFF.md). The ritual is spelled out below.
+
+> The protocol section below is byte-identical to the shared block in CLAUDE.md. If you edit one, edit the other.
+
+## Shared protocol
+
+### Startup ritual (every session)
+
+1. Read `.ai/PROJECT_CONTEXT.md` — architectural truth for this repo.
+2. Read `.ai/CURRENT_TASK.md` — what we're actively working on.
+3. Read `.ai/HANDOFF.md` — exact resume point.
+4. Skim `.ai/DECISIONS.md` for recent entries relevant to the current task.
+5. Run `git log --oneline -15` and `git status`.
+6. Before taking action, state back in two sentences: the current goal and your proposed next action.
+
+### Handoff ritual (session end — limit hit, task complete, or user stop)
+
+1. Update `.ai/HANDOFF.md` to reflect new state. Keep it under ~2K tokens.
+2. If `CURRENT_TASK.md` status changed, update it.
+3. If you made an architectural decision, append to `.ai/DECISIONS.md`.
+4. Append a session entry to `.ai/SESSION_LOG.md`.
+5. If working tree is dirty, commit WIP with `wip(handoff): <one-line summary>`. Do not push unless explicitly asked.
+
+### Writing rules for .ai/ files
+
+- Use model-neutral voice in `HANDOFF.md`, `SESSION_LOG.md`, `DECISIONS.md` ("previous session did X", NOT "Claude did X" or "Codex did X"). Exception: `SESSION_LOG.md` entries include an `<agent>` field in the header.
+- Do not duplicate content between files. `CURRENT_TASK.md` holds the goal, `HANDOFF.md` holds the resume point, `TODO.md` holds the backlog. If unsure where something goes, check `.ai/README.md`.
+- Don't invent facts about the repo. If you're uncertain, write `TODO: confirm` and flag it.
+
+### Project principle
+
+Prefer correct architecture over minimal diff. Flag "simpler approach" tradeoffs for review before taking them.
+
+## Codex-specific notes
+
+### Tooling you do NOT have
+
+- **No GitNexus tools.** Use `grep -r`, `rg`, `git grep`, or `find` for code search. For blast-radius reasoning, grep call sites manually and read the files.
+- **No gstack slash commands** (`/review`, `/ship`, `/qa`, `/browse`, `/investigate`, `/design-review`, `/plan-*`). Run the equivalent work directly: `pytest` for tests, `npm run build` for frontend validation, manual PR description for review flow.
+- **No `/codex` second-opinion command.** You are Codex.
+
+### Git trailer
+
+Every commit: `Co-Authored-By: Codex <noreply@openai.com>`
+
+### Model selection
+
+Handled on OpenAI's side. Do not attempt to set Anthropic model aliases for your own runtime. (The repo's application code still uses Anthropic aliases like `claude-sonnet-4-6` via `settings.get_model_for_action()` — that's runtime config for the product, not your agent.)
+
+### Reviewing Claude's work
+
+When you resume from a Claude session, assume some decisions may have been informed by GitNexus queries or gstack commands whose output isn't in the handoff. If a decision looks unverified from the `.ai/` files alone, either:
+
+- re-verify with `grep`/`rg`/file reads, or
+- flag it in `HANDOFF.md` under "Open questions" so Michael or Claude can confirm on the next handoff.
+
+Do not assume tooling output that isn't written down.

-# CLAUDE.md - Patherly / ResolutionFlow Project Context
+# CLAUDE.md — ResolutionFlow
 
-> **Last Updated:** April 16, 2026
+You are Claude Code, the primary coding agent for ResolutionFlow. OpenAI Codex is the resume agent when you hit session or weekly limits.
 
----
+The first thing to do every session: read [`.ai/PROJECT_CONTEXT.md`](.ai/PROJECT_CONTEXT.md), [`.ai/CURRENT_TASK.md`](.ai/CURRENT_TASK.md), and [`.ai/HANDOFF.md`](.ai/HANDOFF.md). The ritual is spelled out below.
 
-## Project Overview
+> The protocol section below is byte-identical to the shared block in AGENTS.md. If you edit one, edit the other.
 
-**Patherly** (user-facing brand: **ResolutionFlow**) is a **SaaS product for MSP professionals**. It provides troubleshooting decision trees that guide engineers through proven troubleshooting paths, capture decisions and notes, and generate professional ticket documentation.
+## Shared protocol
 
-**Target Market:** MSP companies — IT service providers managing infrastructure and support for multiple clients.
+### Startup ritual (every session)
 
-**SaaS Context:** Multi-tenant design — teams represent MSP companies, trees shared within teams, tiered access (super_admin, team_admin, engineer, viewer).
+1. Read `.ai/PROJECT_CONTEXT.md` — architectural truth for this repo.
+2. Read `.ai/CURRENT_TASK.md` — what we're actively working on.
+3. Read `.ai/HANDOFF.md` — exact resume point.
+4. Skim `.ai/DECISIONS.md` for recent entries relevant to the current task.
+5. Run `git log --oneline -15` and `git status`.
+6. Before taking action, state back in two sentences: the current goal and your proposed next action.

+### Handoff ritual (session end — limit hit, task complete, or user stop)
 
-| Context | Name Used |
-|---------|-----------|
-| Repository / directory / database | `patherly` (internal name) |
-| Docker containers | `resolutionflow_postgres`, `resolutionflow_frontend`, `resolutionflow_backend` |
-| Backend, frontend UI, production URLs | **ResolutionFlow** |
+1. Update `.ai/HANDOFF.md` to reflect new state. Keep it under ~2K tokens.
+2. If `CURRENT_TASK.md` status changed, update it.
+3. If you made an architectural decision, append to `.ai/DECISIONS.md`.
+4. Append a session entry to `.ai/SESSION_LOG.md`.
+5. If working tree is dirty, commit WIP with `wip(handoff): <one-line summary>`. Do not push unless explicitly asked.
 
-- **Brand assets:** `brand-assets/` (source SVGs), `frontend/src/assets/brand/` (app assets), `frontend/public/icons/` (favicon)
-- **Logo:** 30px gradient square (ember orange) + "ResolutionFlow" in Bricolage Grotesque 700
-- **Layout:** Icon rail sidebar (72px default) with hover flyout panels. Pinnable to full 260px sidebar.
-- **Terminology:** User-facing label is "Flows" (not "Trees"). Procedural flows are called "Projects" in the UI. Step Library is called "Solutions Library" in the UI. `tree_type` column values unchanged in DB.
-- **Reference mockups:** `docs/mockups/` (HTML files, open in browser)
+### Writing rules for .ai/ files
 
-## Implementation Principles
+- Use model-neutral voice in `HANDOFF.md`, `SESSION_LOG.md`, `DECISIONS.md` ("previous session did X", NOT "Claude did X" or "Codex did X"). Exception: `SESSION_LOG.md` entries include an `<agent>` field in the header.
+- Do not duplicate content between files. `CURRENT_TASK.md` holds the goal, `HANDOFF.md` holds the resume point, `TODO.md` holds the backlog. If unsure where something goes, check `.ai/README.md`.
+- Don't invent facts about the repo. If you're uncertain, write `TODO: confirm` and flag it.
 
-- Prefer correct architecture over minimal diff
-- If two approaches exist, implement the one that scales, not the one that's faster to write
-- Flag any "simpler approach" tradeoffs for product owner review before proceeding

-## Current State
+## Claude-specific tooling
 
-- **Phase:** Go-to-Market Validation (Pre-PMF)
-- **Backend:** Complete (55+ API endpoints, 100+ integration tests)
-- **Frontend:** Core features complete, Tree Editor functional
-- **Database:** PostgreSQL with Docker, 101 migrations
-- **Detailed status:** [CURRENT-STATE.md](CURRENT-STATE.md)
+### GitNexus code intelligence
 
-### What's In Progress
+Indexed as `resolutionflow`. Earns its cost on cross-cutting work only.
 
-- GTM validation: Shadow & Ship — founder dogfooding for 2 weeks, then 5 colleague pilot
-- Solutions Library spec written (`docs/plans/2026-03-23-solutions-library-design.md`), implementation post-pilot
-- Remaining open issues: #66 Templates + Import/Export, #60 Recurring Issue Detection, #58 Step Feedback Flag
+| Tool | When |
+|---|---|
+| `gitnexus_query({query})` | Find code by concept when you don't know where to look |
+| `gitnexus_context({name})` | Callers/callees of a symbol before touching it |
+| `gitnexus_impact({target, direction})` | Blast radius before editing shared symbols |
+| `gitnexus_rename({symbol_name, new_name, dry_run: true})` | Safe multi-file rename |
 
----
+**Use for:** core shared symbols (`flowpilot_engine`, `unified_chat_service`, auth middleware, `get_db`, shared hooks), cross-file renames, unfamiliar bug traces, refactor safety. **Skip for:** new endpoints, isolated fixes, changes you can read in one file.
 
-## Tech Stack
+Re-indexes automatically on commit (PostToolUse hook). Manual refresh if stale: `npx gitnexus analyze`.
 
-### Backend
-Python FastAPI, PostgreSQL 16 (async SQLAlchemy 2.0 + asyncpg), Alembic, JWT (python-jose) + bcrypt, Pydantic v2, APScheduler 3.x

-## ConnectWise PSA Integration
-
-All reference materials in `docs/connectwise/`. See [CONNECTWISE-API-REFERENCE.md](docs/connectwise/CONNECTWISE-API-REFERENCE.md) first.
-
-### Best Practices Documentation
-
-Read `docs/connectwise/best-practices/` BEFORE implementing any CW API integration code:
-
-- `PSA-API-Requests.md` — HTTP methods, condition syntax, PATCH format. READ FIRST.
-- `PSA-Callbacks.md` — Callback matrix, HMAC verification.
-- `PSA-Pagination.md` — Forward-Only vs Navigable, Link headers.
-- `PSA-Service-Tickets.md` — Ticket field mappings.
-- `PSA-Versioning.md` — Pin `application/vnd.connectwise.com+json; version=2025.16`.
-- `PSA-Cloud-URL-Formatting.md` — Dynamic base URL via `/login/companyinfo/{companyId}`.
-- `Bundled-Requests.md` — Batch via `/system/bundles`.
-- `PSA-Markdown.md` — Notes support markdown.
-- `PSA-Company-Synchronization.md` — Filter companies by Status/Type.
-- `PSA-Data-Protection.md` — Request minimal permissions (MY not ALL).
-
-### Reference Files (read in this order)
-
-1. `docs/connectwise/CONNECTWISE-API-REFERENCE.md` — Auth patterns, endpoint map, field mappings.
-2. `docs/connectwise/connectwise-psa-resolutionflow-reference.json` — Extracted OpenAPI 3.0.1 spec (670 endpoints, 342 schemas).
-3. `docs/connectwise/connectwise-psa-openapi-full.json` — Full spec (1838 endpoints). Only if you need something outside the subset.
-
-### Key Implementation Rules
-
-- Auth: API Key auth (Base64 of `companyId+publicKey:privateKey`) + `clientId` header on every request
-- `clientId` is server-side config (`CW_CLIENT_ID` in `config.py`) — identifies ResolutionFlow app, NOT per-tenant. Per-connection: `company_id`, `public_key`, `private_key`, `server_url`
-- All PSA code in `services/psa/` — `PSAProvider` abstract base, `ConnectWiseProvider` impl, `PsaProviderRegistry` for multi-PSA dispatch
-- PSA endpoints in `api/endpoints/integrations.py` — connection CRUD, ticket ops, member mapping
-- Credentials encrypted via `services/psa/encryption.py` (Fernet); stored per-team, never per-user
-- In-memory TTL cache in `services/psa/cache.py` for board/status/priority lookups
-- Integration flows: Session → Ticket Notes via `POST /service/tickets/{id}/notes`; Ticket Context → FlowPilot via ticket details/company/configs; Callbacks via `/system/callbacks`

-## Critical Lessons Learned
-
-> Lessons 1-70 archived to `docs/LESSONS-ARCHIVE.md` — fixes are baked into the codebase.
-
-**71. Enhancement/branch_addition proposals cannot be directly approved:** Backend returns 400 — requires `modified_flow_data` via "Edit & Publish". Only `new_flow` proposals support direct approve.
-
-**72. `ai_sessions.status` column is `VARCHAR(30)`:** Must fit `requesting_escalation` (23 chars). Verify length when adding new status values.
-
-**73. `get_db` rolls back on exception:** Prevents `InFailedSQLTransaction` cascade. Never remove the `await session.rollback()` in the dependency.
-
-**74. FlowPilot action bar height chain:** `ViewTransitionOutlet` wrapper needs `flex flex-col`. If action bar disappears, walk `getBoundingClientRect()` from `app-shell` down.
-
-**75. Dashboard prefill auto-submits:** `StartSessionInput` passes `{ state: { prefill } }`. Both `FlowPilotSessionPage` and `AssistantChatPage` auto-submit via `useEffect` + `prefillHandledRef` guard.
-
-**76. Active session navigation guard:** `FlowPilotSessionPage` uses `useBlocker` to intercept navigation. "Pause & Leave" auto-pauses before proceeding.
-
-**77. Prefer manual Alembic migrations for targeted changes:** `--autogenerate` picks up all table drift. For single-column fixes, use `alembic revision -m "desc"` and write `op.alter_column()` manually.
-
-**78. Landing page subtitle is "AI-Powered Troubleshooting for MSPs":** Appears on login, register, and `<title>`. Not "Decision Tree Platform".
-
-**79. Custom modals must be mobile-responsive:** Use `items-end sm:items-center` + `max-w-full sm:max-w-lg`. See `Modal.tsx` and `PrepareSessionModal.tsx`.
-
-**80. TopBar search collapses to icon on mobile:** Full bar (`hidden sm:block`) + icon fallback (`sm:hidden`). Both open `CommandPalette`.
-
-**81. Never use `transition: all` in landing.css:** Specify exact properties. `transition: all` animates layout and causes jank.
-
-**82. `bun` requires PATH setup:** `export BUN_INSTALL="$HOME/.bun" && export PATH="$BUN_INSTALL/bin:$PATH"`. Chromium deps: `libatk1.0-0 libatk-bridge2.0-0 libcups2 libxkbcommon0 libatspi2.0-0 libxcomposite1 libxdamage1 libxfixes3 libxrandr2 libgbm1 libasound2`.
-
-**84. AI session `abandoned` status is fully wired:** `POST /ai-sessions/{id}/abandon` with optional `reason`. Frontend: `aiSessionsApi.abandonSession()` → `useFlowPilotSession().abandonSession()`.
-
-**85. Date range filter end dates must use end-of-day:** Set `toDate.setHours(23, 59, 59, 999)`. For string inputs append `T23:59:59.999Z`. See `SessionHistoryPage.tsx`.
-
-**86. Script Builder:** `/script-builder` — `ScriptBuilderSession` model, `script_builder_service.py`, endpoints at `/scripts/builder/`. FlowPilot handoff via `action_type: "open_script_builder"` + sessionStorage context.
-
-**87. FlowPilot must ask GUI vs script preference:** Ask BEFORE suggesting either approach. See `FLOWPILOT_SYSTEM_PROMPT` in `flowpilot_engine.py`.
-
-**88. Charcoal palette:** Sidebar `#0e1016`, page `#16181f`, cards `#1e2028`, borders `#2a2e3a`. All via CSS variables in `index.css` `@theme`. Accent is electric blue (#60a5fa).
-
-**92. `tsc -b` in Dockerfile enforces `noUnusedLocals`/`noUnusedParameters` as hard errors.** After refactors, trace every import and destructured prop. Check IDE yellow squiggles before pushing.
-
-**93. FlowPilot actions live in the page header, not a bottom bar:** Resolve/Escalate/Share Update in header. Desktop: inline + `⋯` overflow (Pause/Close). Mobile: single `⋯`. Bottom = message input only.
-
-**94. Frontend chat uses `unified_chat_service`, not `assistant_chat_service`:** `AssistantChatPage` → `/ai-sessions/{id}/chat` → `unified_chat_service.py`. Never wire chat into `assistant_chat.py`.
-
-**95. Image upload → AI vision:** `uploadsApi.upload()` → `upload_ids` in message → backend fetches S3 → `storage_service.resize_image_for_vision()` (Pillow, 1568px, PNG→JPEG) → base64 → Claude multimodal. Max 3 images/message. Images NOT stored in history.
-
-**96. `bg-accent` is electric blue — never use for code/kbd.** Use `bg-code` for code blocks, `bg-white/[0.12]` for inline code/badges, `bg-white/[0.08]` for kbd.
-
-**97. Railway S3 provisioned:** Bucket `resolutionflow-uploads`. Variables: `STORAGE_ENDPOINT`, `STORAGE_ACCESS_KEY`, `STORAGE_SECRET_KEY`, `STORAGE_BUCKET_NAME`, `STORAGE_REGION`. boto3 in `storage_service.py`.
-
-**98. `lazyWithRetry` for lazy routes:** Use instead of `React.lazy` — auto-reloads on chunk failures with 10s sessionStorage debounce.
-
-**99. `text-secondary` renders invisible on dark backgrounds:** Maps to `--color-secondary` (dark surface). Use `text-muted-foreground` (`#848b9b`) for readable secondary text. Never use `text-muted` for body text.
-
-**100. Hover pop-out card pattern:** `pointer-events-none` on scrim (`z-40`), `z-50` expanded card with own `onClick`, dismiss via `onMouseLeave`. Never put handlers on scrim.
-
-**101. AI marker format compliance:** `[QUESTIONS]`, `[ACTIONS]`, `[FORK]` parsed by `unified_chat_service.py`. History stores `display_content` (stripped). Each user message gets `[SYSTEM: ...]` reminder appended in `_call_anthropic_cached()`.
-
-**102. TaskLane activation must happen in ALL chat response paths:** Three paths in `AssistantChatPage.tsx` — `handleSend`, `sendPrefill`, `handleResumeNew`. All must check `response.actions`/`response.questions` and call `setShowTaskLane(true)`.
-
-**103. Docker not available in code-server:** Use VPS SSH: `docker exec resolutionflow_postgres psql -U postgres -d resolutionflow -t -c "SQL"`. Python also not available in container.
-
-**104. `landing.css` uses `--lp-*` variables:** Never use `var(--color-*)` tokens in `landing.css`. Extend the `--lp-*` palette for new landing page colors.
-
-**105. `npm run build` fails with `EACCES` on `dist/` in code-server:** Use `npx tsc -b` to verify TypeScript without writing to `dist/`.
-
-**106. Guard async "select item → load data → apply state" flows:** Use `currentSelectionRef = useRef(id)` — update on every switch, bail after each `await` if ref no longer matches. See `AssistantChatPage.tsx` `currentChatRef`.
-
-**107. Startup routines use `_admin_session_factory()`:** RLS is enabled; `get_db()` at startup has no `app.current_account_id`, so queries return 0 rows. Affects lifespan, `ensure_service_account`, seed scripts.
-
-**108. Tables with no `account_id` (never add to RLS migrations):** `script_categories`, `platform_steps`, `template_trees`, `plan_feature_defaults`, `accounts`. Scan at class level, not file level — one `.py` file can have multiple classes with different columns.
-
-**109. `tree_shares.account_id` must equal `tree.account_id`:** Use tree owner's tenant, not the actor's. Cross-tenant admin shares become invisible after RLS enforcement.
-
-**110. Backfill `account_id` migrations require service-code audit:** Grep all `ModelClass(` sites, verify `account_id=` is passed. SQLAlchemy accepts `None` silently; RLS WITH CHECK surfaces it at runtime as `InsufficientPrivilegeError`.
-
-**111. Global Axios interceptor fires before component `.catch()`:** Fix optional-data endpoints at the source — return `[]`/`{}` on provider failure instead of raising 502. See `list_boards` in `integrations.py`.
-
-## RBAC & Permissions
-
-- **Role hierarchy:** super_admin > team_admin > engineer > viewer
-- **Team Admin:** `role='engineer'` + `is_team_admin=True` + valid `team_id`
-- **Backend deps:** `get_current_active_user`, `require_engineer_or_admin` (blocks viewers), `require_admin` (super admin only)
-- **Never use** `role == "admin"` — use `is_super_admin` instead
-- **Frontend:** `usePermissions()` hook for all permission checks
-- **Centralized:** `backend/app/core/permissions.py`, `frontend/src/hooks/usePermissions.ts`
-
----
-
-## Design System
-
-**Source of truth:** [DESIGN-SYSTEM.md](DESIGN-SYSTEM.md) — always read before visual/UI decisions.
-
-- **Theme:** Flat, high-contrast dark (Sentry/PostHog-inspired). No glass morphism, no backdrop blur, no gradients on surfaces. Fonts: IBM Plex Sans (body), Bricolage Grotesque (headings), JetBrains Mono (code).
-- **Backgrounds:** `bg-page` (`#16181f`), `bg-sidebar` (`#0e1016`), `bg-card` (`#1e2028`), `bg-elevated` (`#2a2d38`)
-- **Cards:** `bg-card` + 1px `border-default` (`#2a2e3a`), 8px radius. Hover: `border-hover` (`#3d4252`)
-- **Buttons:** Primary: solid `accent` (#60a5fa / #2563eb), white text, 5px radius. Ghost: transparent + 1px border.
-- **Inputs:** `bg-input` (`#252830`) + 1px `border-default`, 5px radius. Focus: `border-color: accent` + `box-shadow: 0 0 0 2px accent-dim`
-- **Text:** `text-heading` → `text-primary` → `text-muted-foreground` (`#848b9b`). **NEVER `text-secondary`** — maps to a dark surface color.
-- **Functional colors:** `#34d399` success, `#fbbf24` warning, `#f87171` danger, `#67e8f9` info — each has `-dim` at 10% opacity
-- **Deprecated:** No `glass-card`, `backdrop-filter: blur()`, ambient orbs, ember orange (`#f97316`), or cyan as accent
-
----
-
-## Frontend Patterns
-
-- **Component guidelines:** Use `cn()` from `@/lib/utils`, Lucide icons (wrap in `<span>` for title), modals with fixed header/footer
-- **Type organization:** Create in `types/`, export from `types/index.ts`, import with `import type { T } from '@/types'`
-- **Custom step flow:** `CustomStepModal` → `PostStepActionModal` → `ContinuationModal`. Use `findCustomStep()` not `findNode()` for custom step UUIDs.
-- **Session sharing:** `ShareSessionModal` + `SharedSessionPage`. Utils in `lib/sessionShare.ts`. Share URLs: `/shared/sessions/:token`.
-- **Routing helper:** Use `getTreeNavigatePath()` and `getTreeEditorPath()` from `@/lib/routing` for all tree/session navigation.
-- **Account section:** `AccountLayout` has NO sidebar nav. New account pages: route under `account` children in `router.tsx` + link card in `AccountSettingsPage`.
-- **Dashboard cockpit:** `QuickStartPage` — `StartSessionInput` + `PendingEscalations`, `ActiveFlowPilotSessions`, `RecentFlowPilotSessions`. Collapsible section for `PerformanceCards`, `KnowledgeBaseCards`, `TeamSummary`.
-- **Sidebar:** Amber "New Session" → Home → RESOLVE → KNOWLEDGE (Flows, Scripts) → INSIGHTS. Footer: Account, Pin/Unpin.

-## Common Tasks
-
-- **New endpoint:** Create in `endpoints/` → add to `router.py` → schema in `schemas/` → tests → frontend API client
-- **New page:** Create in `pages/` → route in `router.tsx` → nav link in `AppLayout.tsx`
-- **New public route:** Add at top level in `router.tsx` (alongside `/login`) — NOT inside `ProtectedRoute`/`AppLayout`
-- **Schema change:** Update model → `alembic revision -m "desc"` (no `--rev-id`) → review → `alembic upgrade head`
-- **New frontend API module:** Types in `types/` → export from `types/index.ts` → client in `api/` → export from `api/index.ts`

-## Coding Standards
-
-### Python
-Type hints everywhere, async/await for DB, Pydantic validation, `DateTime(timezone=True)` always.
-
-### TypeScript
-Interfaces for all data, `const` over `let`, functional components + hooks.
-
-### Git
-- Format: `type: description` (feat, fix, refactor, docs, test, chore)
-- Always include `Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>`
-- Create feature branch BEFORE committing: `git checkout -b feat/feature-name`
-- **Remote is Gitea:** Push to `gitea.resolutionflow.com/chihlasm/resolutionflow`. Mirrors to GitHub via `.gitea/workflows/mirror-to-github.yml` — never push directly to GitHub.
-
-### After Completing Work
-1. Update `CURRENT-STATE.md`
-2. Update `03-DEVELOPMENT-ROADMAP.md`
-3. Close related GitHub Issues: `gh issue close #N`
-4. Update `CLAUDE.md` if new patterns or lessons emerged
-

-
-## gstack (Browser & Workflow Skills)
-
-**Web browsing:** Always use `/browse`. Never use `mcp__claude-in-chrome__*` tools.
-
-**Skills:** `/office-hours` · `/plan-ceo-review` · `/plan-eng-review` · `/plan-design-review` · `/design-consultation` · `/review` (PR review) · `/ship` · `/browse` (headless QA) · `/qa` (QA + fix) · `/qa-only` · `/design-review` (visual QA) · `/setup-browser-cookies` · `/retro` · `/investigate` · `/document-release` · `/codex` · `/careful` · `/freeze` · `/unfreeze` · `/guard` · `/gstack-upgrade`
-

-
-## Deployment (Railway)
-
-- **Production:** `resolutionflow.com` (frontend), `api.resolutionflow.com` (backend)
-- Deploy pipeline: push to Gitea → mirrors to GitHub → Railway watches `main`
-- PR envs: need manual domain generation + `VITE_API_URL` with `https://` prefix
-- `ALLOW_RAILWAY_ORIGINS=true` enables CORS for `*.up.railway.app`
-- Shared Variables auto-propagate to all PR envs — use for `ANTHROPIC_API_KEY` etc.
-- Super admin: `backend/make_superadmin_simple.py list|<email>`

-# GitNexus — Code Intelligence
-
-This project is indexed by GitNexus as **resolutionflow**. Use it selectively — for routine additive work (new endpoints, new components, isolated fixes) just read the files directly. GitNexus earns its cost when you're about to touch something genuinely central with many callers.
-
-> If any GitNexus tool warns the index is stale, run `npx gitnexus analyze` in terminal first.
-
-## When to Use It
-
-**Use GitNexus when:**
-- Touching a core shared symbol with many callers — `flowpilot_engine`, `unified_chat_service`, auth middleware, `get_db`, shared hooks
-- Renaming anything used across multiple files
-- Tracing an unfamiliar bug through a call chain you haven't read
-- Assessing whether a refactor is safe before starting
-
-**Skip GitNexus when:**
-- Adding a new endpoint, component, or isolated feature
-- Fixing a bug in a self-contained file
-- Making changes you can already see the full scope of by reading the file
-
-## Useful Tools
-
-| Tool | When to use | Command |
-|------|-------------|---------|
-| `query` | Find code by concept when you don't know where to look | `gitnexus_query({query: "auth validation"})` |
-| `context` | See all callers/callees of a symbol before touching it | `gitnexus_context({name: "symbolName"})` |
-| `impact` | Blast radius check before editing a shared symbol | `gitnexus_impact({target: "X", direction: "upstream"})` |
-| `rename` | Safe multi-file rename | `gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true})` |
-
-## Keeping the Index Fresh
-
-A PostToolUse hook re-indexes automatically after `git commit`. To manually refresh:
-
-```bash
-npx gitnexus analyze
-```
-
-<!-- gitnexus:end -->
+Always use alias form (`claude-sonnet-4-6`, `claude-opus-4-6`, etc.) via `settings.get_model_for_action()`. Never hardcode a dated model ID.

+# ResolutionFlow — Dev Environment Setup & Operations Guide
 
-## Server Overview
+> **Scope:** Stand up a working ResolutionFlow dev environment from scratch on any Linux host (VPS, on-prem Proxmox LXC/VM, bare metal). Self-contained — do not read another doc to get the dev stack running.
+> **Last rewritten:** April 2026, post-Hostinger-VPS deprecation, ahead of Proxmox migration.
+> **Audience:** You (returning to the project), a teammate, or a fresh Claude Code session.
 
-- **Provider:** Hostinger KVM VPS (srv1522117)
-- **IP Address:** 46.202.92.250
-- **OS:** Ubuntu 24.04 LTS
-- **CPU:** 2 vCPU cores
-- **RAM:** 8GB
-- **Disk:** 100GB NVMe SSD
-- **Swap:** 4GB (`/swapfile`, swappiness=10)
+If you're picking up mid-migration and need to know what code state is on the current branch, read `docs/FlowAssist_Migration/MIGRATION-HANDOFF.md` first.
 
-## Architecture
+---
 
-All services run as Docker containers on the host, managed via SSH or from the VS Code Server integrated terminal.
+## 1. What this project needs, regardless of host
 
-```
-Host (root@srv1522117)
-├── Traefik                       → reverse proxy + auto SSL (Let's Encrypt)
-├── VS Code Server                → browser IDE at https://code.resolutionflow.com
-└── ResolutionFlow Stack
-    ├── resolutionflow_frontend   → Vite/React on port 5173
-    ├── resolutionflow_backend    → FastAPI/Uvicorn on port 8000
-    └── resolutionflow_postgres   → PostgreSQL 16 + pgvector on port 5432
-```
+These are non-negotiable. If your host can't provide them, fix that before anything else.
 
-## Access URLs
+| Component | Required version | Notes |
+|---|---|---|
+| **Linux** | any mainstream distro | Ubuntu 22.04+ / Debian 12+ tested; Alpine fine for containers |
+| **Python** | 3.11+ | Backend and migrations |
+| **Node.js** | 20.19+ | Vite 7 fails on older versions — CLAUDE.md Lesson 63 |
+| **PostgreSQL** | 16 | `gen_random_uuid()` + `jsonb` + RLS are all leaned on |
+| **Docker + Docker Compose** | recent | Only if you are running Postgres and/or backend as containers |
+| **Git** | recent | |
 
-| Service | URL |

-## Docker Layout
+---
+
+## 2. Architectural shape
+
+The project is three services plus your editor. Keep these facts in mind regardless of topology:
 
 ```
-/docker/
-├── traefik/
-│   ├── docker-compose.yml    → Traefik reverse proxy
-│   └── .env                  → ACME_EMAIL for Let's Encrypt
-└── vscode/
-    ├── docker-compose.yml    → VS Code Server
-    └── .env                  → CODE_PASSWORD
+Your browser
+   ├─► code-server         (editor, optional — usually port 8080 or behind TLS)
+   ├─► frontend (Vite)     (dev server, port 5173)
+   └─► backend (FastAPI)   (dev server, port 8000)
+                               │
+                               └─► PostgreSQL (port 5432)
 ```
 
-Project lives inside the VS Code Server Docker volume:
+**The frontend calls the backend by URL at runtime.** The frontend does not proxy through the backend. Whatever URL your browser uses to reach the backend is what `VITE_API_URL` must be set to, **baked in at build time**. Changing `VITE_API_URL` requires rebuilding the frontend.
+
+**The backend calls the database by URL at runtime.** The URL depends on where Postgres is relative to the backend — Docker service name if both are in the same compose network, `localhost` if Postgres is native on the same host, or a DNS name if they're in separate containers/VMs.
+
+**CORS is configured explicitly.** The backend's `CORS_ORIGINS` list must include every origin your browser will use to reach the frontend. A missing origin shows up as failed preflight requests.
+
+---
+
+## 3. Topology choices — pick one before you start
+
+The project is agnostic to topology, but each shape has different setup steps.
+
+### Option A — all-in-one LXC/VM/host (simplest)
+
+Postgres, backend, and frontend all run on one Linux host. code-server runs on the same host or a sibling. No Docker required. Best for a single-developer Proxmox LXC.
+
+### Option B — Docker Compose on one host
+
+Postgres, backend, and frontend run as Docker containers on one host. code-server runs outside the compose network (on the host or in another container). This is how the old Hostinger VPS was configured. Best if you want reproducible container images.
+
+### Option C — split services across containers/VMs
+
+Postgres in one container/VM, backend and frontend in another, code-server in a third. Most complex; requires explicit networking between them. Use only if you have a specific reason.
+
+**Pick one and stick with it for the entire setup.** Mixing Options A and B halfway through is where setup runs off the rails.
+
+---
+
+## 4. Per-host configuration
+
+These values are specific to your host. Fill them in once and reference them by name throughout the rest of the doc.
+
 ```
-/var/lib/docker/volumes/vscode_vscode-data/_data/resolutionflow/
+DEV_HOST              = <hostname or IP your browser uses, e.g. dev.internal, 10.0.0.42>
+DEV_HOST_SCHEME       = <http or https; http is fine for internal dev, https if behind a TLS proxy>
+FRONTEND_PORT         = 5173
+BACKEND_PORT          = 8000
+POSTGRES_PORT         = 5433  # host-side port. 5433 is the recommended default on any shared host to avoid collision with a host-level Postgres. The container's internal port stays 5432.
+POSTGRES_DB_NAME      = resolutionflow
+POSTGRES_USER         = postgres
+POSTGRES_PASSWORD     = <local-dev-password; anything, this is not prod>
+SECRET_KEY            = <openssl rand -hex 32 — generate fresh per host, do not reuse>
+ANTHROPIC_API_KEY     = <from https://console.anthropic.com>
+GOOGLE_AI_API_KEY     = <optional, only if using Gemini as a fallback>
 ```
 
-## VS Code Server
+Store these somewhere you can copy from during setup. Do not commit them.
 
-- **Container user:** `coder` (UID 1000)
-- **Home directory:** `/home/coder`
-- **Project location:** `/home/coder/resolutionflow`
-- **Host volume path:** `/var/lib/docker/volumes/vscode_vscode-data/_data`
-- **Access URL:** `https://code.resolutionflow.com`
-- **HTTPS:** Auto-provisioned via Traefik + Let's Encrypt
+> **Naming note:** the canonical database name is `resolutionflow`. If you see `patherly` in a config file, that's drift from an earlier rename and is being swept in a separate commit — use `resolutionflow`. CLAUDE.md tracks the live-code files that still reference `patherly`.
 
-### Compose File Location
-`/docker/vscode/docker-compose.yml`
+---
 
-## Traefik
+## 5. Setup procedure
 
-Handles reverse proxying and automatic SSL for all services. HTTP automatically redirects to HTTPS.
+Run these in order. Stop at the first failure and investigate.
 
-### Adding A New Service Behind Traefik
-
-Add these labels to any new Docker service:
-
-```yaml
-labels:
-  - "traefik.enable=true"
-  - "traefik.http.routers.<n>.rule=Host(`subdomain.resolutionflow.com`)"
-  - "traefik.http.routers.<n>.entrypoints=websecure"
-  - "traefik.http.routers.<n>.tls.certresolver=letsencrypt"
-  - "traefik.http.services.<n>.loadbalancer.server.port=<port>"
-```
-
-Also create an A record in DNS pointing the subdomain to `46.202.92.250`.
-
-## ResolutionFlow Dev Stack
-
-### Important: No Docker Inside VS Code Container
-
-The VS Code Server container does NOT have Docker. All `docker compose` commands must be run via SSH as root on the host.
-
-### Environment Files
-
-| File | Purpose |
-|---|---|
-| `.env` | Root — Docker Compose interpolation (`SECRET_KEY`, `ANTHROPIC_API_KEY`, `GOOGLE_AI_API_KEY`, `POSTGRES_PORT`) |
-| `backend/.env` | Backend source of truth — all FastAPI settings, API keys, DB URLs, CORS |
-| `frontend/.env` | Frontend — `VITE_API_URL` pointing to backend |
-
-### Critical Remote Access Config
-
-**`frontend/.env`:**
-```
-VITE_API_URL=http://46.202.92.250:8000
-```
-
-**`backend/.env`:**
-```
-CORS_ORIGINS=["http://localhost:3000","http://localhost:5173","http://127.0.0.1:3000","http://127.0.0.1:5173","http://46.202.92.250:5173","http://46.202.92.250:3000","https://resolutionflow.com","https://www.resolutionflow.com"]
-FRONTEND_URL=http://46.202.92.250:5173
-DATABASE_URL=postgresql+asyncpg://postgres:postgres@db:5432/resolutionflow
-DATABASE_URL_SYNC=postgresql://postgres:postgres@db:5432/resolutionflow
-```
-
-Note: `DATABASE_URL` uses `@db:5432` (Docker service name), not `@localhost`.
-
-**`docker-compose.dev.yml`:**
-```yaml
-- VITE_API_URL=http://46.202.92.250:8000
-```
-
-### Starting the Dev Environment
-
-SSH into host as root:
+### 5.1 Install system dependencies
 
 ```bash
-cd /var/lib/docker/volumes/vscode_vscode-data/_data/resolutionflow
-docker compose -f docker-compose.dev.yml up -d
+# Ubuntu / Debian
+sudo apt update && sudo apt install -y \
+  git curl build-essential \
+  python3.11 python3.11-venv python3-pip \
+  postgresql-client   # not the server — only if running Postgres natively
+
+# Node 20 via nvm (survives container rebuilds if stored in a volume)
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
+export NVM_DIR="$HOME/.nvm" && source "$NVM_DIR/nvm.sh"
+nvm install 20
+nvm alias default 20
 ```
 
-### Running Migrations (Fresh Database)
+For Option B (Docker Compose), also:
 
 ```bash
-cd /var/lib/docker/volumes/vscode_vscode-data/_data/resolutionflow
+curl -fsSL https://get.docker.com | sh
+sudo usermod -aG docker $USER   # log out and back in for this to take effect
+```
+
+### 5.2 Clone the repo
+
+```bash
+git clone https://gitea.resolutionflow.com/chihlasm/resolutionflow.git
+# or the GitHub mirror:
+# git clone https://github.com/chihlasm/resolutionflow.git
+cd resolutionflow
+
+# Check out the working branch if you're continuing mid-migration.
+git fetch origin
+git checkout feat/flowpilot-migration
+```
+
+### 5.3 Start PostgreSQL
+
+**Option A (native Postgres on the host):**
+
+```bash
+sudo apt install -y postgresql-16
+sudo -u postgres psql -c "CREATE DATABASE resolutionflow;"
+sudo -u postgres psql -c "ALTER USER postgres PASSWORD 'postgres';"
+# Adjust pg_hba.conf if you need non-local connections.
+```
+
+**Option B (Postgres via Docker Compose):** The repo has a `docker-compose.dev.yml` at the root. Check its Postgres service for the container name, port mapping, and volume. The local compose defaults use container name `resolutionflow_postgres`, database `resolutionflow`, and host-side port `5433` (mapped to the container's internal `5432`) — see CLAUDE.md Lesson 65. The host-side `5433` is the recommended default on any shared host: it keeps the port free for a host-level Postgres if you ever need one. The compose file also defines explicit `command:` directives on both `backend` and `frontend` to force `--host 0.0.0.0`, and expects the caller to pass `REPO_ROOT` (see 5.4) for bind-mount resolution. Confirm what the compose file actually says on your branch before trusting these values.
+
+```bash
+docker compose -f docker-compose.dev.yml up -d db
+docker compose -f docker-compose.dev.yml logs db    # wait for "ready to accept connections"
+```
+
+**Verify:**
+
+```bash
+# From the host (Option A) or the backend container/LXC (Option B):
+psql -h <db-host> -p <POSTGRES_PORT> -U postgres -d resolutionflow -c "SELECT now();"
+```
+
+### 5.4 Write the `.env` files
+
+The repo expects three env files. Create each one:
+
+**`backend/.env`** — backend source of truth:
+
+```bash
+APP_NAME=ResolutionFlow
+DEBUG=true
+
+# DB URLs — `<db-host>` is `localhost` for Option A, the Docker service name
+# (e.g. `db`) for Option B, or the DB container/VM hostname for Option C.
+DATABASE_URL=postgresql+asyncpg://postgres:postgres@<db-host>:<POSTGRES_PORT>/resolutionflow
+DATABASE_URL_SYNC=postgresql://postgres:postgres@<db-host>:<POSTGRES_PORT>/resolutionflow
+
+# Auth
+SECRET_KEY=<SECRET_KEY>
+ACCESS_TOKEN_EXPIRE_MINUTES=5
+REFRESH_TOKEN_EXPIRE_DAYS=7
+REQUIRE_INVITE_CODE=true
+
+# AI providers
+AI_PROVIDER=anthropic
+ANTHROPIC_API_KEY=<ANTHROPIC_API_KEY>
+GOOGLE_AI_API_KEY=<GOOGLE_AI_API_KEY or leave unset>
+
+# FlowPilot MCP telemetry — leave on so the Phase 0.5 baseline data keeps accruing
+ENABLE_MCP_MICROSOFT_LEARN=true
+
+# CORS + frontend URL
+FRONTEND_URL=<DEV_HOST_SCHEME>://<DEV_HOST>:<FRONTEND_PORT>
+CORS_ORIGINS=["http://localhost:5173","http://127.0.0.1:5173","<DEV_HOST_SCHEME>://<DEV_HOST>:<FRONTEND_PORT>"]
+```
+
+**`frontend/.env.local`** — frontend build-time config:
+
+```bash
+VITE_API_URL=<DEV_HOST_SCHEME>://<DEV_HOST>:<BACKEND_PORT>
+```
+
+Optional PostHog (CLAUDE.md Lesson 64 — enables product analytics locally):
+
+```bash
+VITE_PUBLIC_POSTHOG_KEY=<from PostHog project settings>
+VITE_PUBLIC_POSTHOG_HOST=https://us.i.posthog.com
+```
+
+**Repo root `.env`** — only needed for Option B (Docker Compose interpolation):
+
+```bash
+SECRET_KEY=<SECRET_KEY>
+ANTHROPIC_API_KEY=<ANTHROPIC_API_KEY>
+GOOGLE_AI_API_KEY=<GOOGLE_AI_API_KEY or leave unset>
+POSTGRES_PORT=<POSTGRES_PORT>
+# Absolute host-side path to the repo root. REQUIRED whenever docker-compose is
+# invoked from inside a container (e.g. a code-server container with the host
+# Docker socket mounted in). Without it, the bind mounts in
+# docker-compose.dev.yml (`${REPO_ROOT}/backend:/app`, `${REPO_ROOT}/frontend:/app`)
+# resolve against the CLI's CWD — a path the host daemon cannot see — and
+# Docker silently creates empty directories there instead of mounting the code.
+# If you run docker compose directly on the host shell, you can set this to `.`
+# or the absolute path of the repo; being explicit is safer either way.
+REPO_ROOT=/absolute/path/to/resolutionflow
+```
+
+> **Never commit any `.env` file.** The `.gitignore` already covers this.
+
+### 5.5 Run the backend setup
+
+**Option A (native):**
+
+```bash
+cd backend
+python3.11 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+
+# Migrate the DB to head.
+alembic upgrade head
+```
+
+**Option B (Docker):**
+
+```bash
+docker compose -f docker-compose.dev.yml up -d backend
 docker compose -f docker-compose.dev.yml run --rm backend alembic upgrade head
 ```
 
-### Seeding Test Users
+**Expected alembic head** (as of `feat/flowpilot-migration`): `f07010f17b01`. If `alembic current` shows anything else after `upgrade head`, something has gone wrong — stop and investigate.
+
+### 5.6 Seed test users
 
 ```bash
+# Option A
+cd backend && source venv/bin/activate
+python -m scripts.seed_test_users
+
+# Option B
 docker exec resolutionflow_backend python -m scripts.seed_test_users
 ```
 
-Test accounts (password: `TestPass123!`):
+Test users (all share password `TestPass123!`):

+| `engineer@resolutionflow.example.com` | engineer |
+| `pro@resolutionflow.example.com` | solo pro |
 
-### Rebuilding After Config Changes
+### 5.7 Run the backend
+
+**Option A:**
+
+```bash
+cd backend && source venv/bin/activate
+uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload
+```
+
+**Option B:** Already running from `docker compose up -d backend`. Tail logs:
+
+```bash
+docker compose -f docker-compose.dev.yml logs -f backend
+```
+
+**Verify:** `curl <DEV_HOST_SCHEME>://<DEV_HOST>:<BACKEND_PORT>/api/docs` — OpenAPI docs page loads.
+
+### 5.8 Run the frontend
+
+**Option A:**
+
+```bash
+cd frontend
+npm install
+npm run dev -- --host 0.0.0.0 --port 5173
+```
+
+**Option B:**
 
-**Frontend** (Vite bakes env vars at build time — requires rebuild):
 ```bash
-cd /var/lib/docker/volumes/vscode_vscode-data/_data/resolutionflow
 docker compose -f docker-compose.dev.yml up -d --build frontend
 ```
 
-**Backend** (restart only):
+**Verify:** Open `<DEV_HOST_SCHEME>://<DEV_HOST>:<FRONTEND_PORT>` in your browser. Log in with one of the test users. Navigate to `/pilot` — the FlowPilot session page should render.
+
+---
+
+## 6. Verification — proof the env actually works
+
+Run these after setup. Every item has a concrete expected outcome.
+
+### 6.1 Database schema is at the right version
+
 ```bash
+# Option A
+cd backend && source venv/bin/activate && alembic current
+# Option B
+docker compose -f docker-compose.dev.yml run --rm backend alembic current
+```
+
+Expected: `f07010f17b01 (head)` on the `feat/flowpilot-migration` branch. On `main`, expected: `074 (head)`.
+
+### 6.2 Alembic reversibility
+
+```bash
+alembic downgrade -1    # should complete cleanly
+alembic upgrade head    # should return to f07010f17b01
+```
+
+If either step fails, the migration has a bug and Phase 2 cannot start.
+
+### 6.3 Prompt-cache hit verification (the deferred Phase 0 TODO)
+
+`backend/app/core/ai_provider.py` module docstring has a `TODO(phase0-verify)` note describing this. Procedure:
+
+1. Confirm `AI_PROVIDER=anthropic` and `ANTHROPIC_API_KEY` is set in `backend/.env`.
+2. Start the backend with log level INFO or lower.
+3. In the UI, open `/pilot` and send a chat message. Wait a few seconds for the response.
+4. Send a second chat message in the same session, within 5 minutes of the first.
+5. In backend logs, grep for lines containing `anthropic.cache`:
+
+   ```bash
+   # Option A
+   grep 'anthropic.cache' <log-path>
+   # Option B
+   docker compose -f docker-compose.dev.yml logs backend | grep 'anthropic.cache'
+   ```
+
+6. Expected: two `anthropic.cache` log events. First has `cache_creation_input_tokens > 0`. Second has `cache_read_input_tokens > 0`.
+7. If the second shows zero reads, inspect the prompt prefix for silent invalidators (timestamps, unsorted JSON keys, varying tool list ordering). Fix before proceeding with any Phase 2 work.
+
+### 6.4 Frontend build is TypeScript-clean
+
+```bash
+cd frontend
+npx tsc -b        # no errors
+npm run build     # no errors
+```
+
+CLAUDE.md Lesson 105 notes that `npm run build` may fail with an `EACCES` on `dist/` inside code-server — that is a Docker filesystem permission issue, not a real build error. Use `npx tsc -b` to verify TypeScript cleanliness in that case.
+
+### 6.5 `/assistant` → `/pilot` redirect
+
+Open `<DEV_HOST_SCHEME>://<DEV_HOST>:<FRONTEND_PORT>/assistant/<some-real-session-id>` in the browser. Expected: URL changes to `/pilot/<that-id>`; the FlowPilot session page renders. Bare `/assistant` redirects to bare `/pilot`.
+
+### 6.6 Dispatcher de-branching
+
+Navigate to the dashboard. Click a session in `ActiveFlowPilotSessions` or `RecentFlowPilotSessions`. Expected: routes to `/pilot/:id` regardless of the session's `session_type` value. (Check the browser URL bar.)
+
+### 6.7 CORS
+
+Open the browser DevTools Network tab, navigate to any backend-hitting page. Expected: no CORS errors. If you see "blocked by CORS policy," the missing origin needs adding to `backend/.env`'s `CORS_ORIGINS`.

+
+## 8. Troubleshooting
+
+### CORS errors in the browser
+
+The backend did not accept the origin your browser used. Check `backend/.env`'s `CORS_ORIGINS` — it must include the exact scheme + host + port the browser sent. Restart the backend after editing.
+
+### `VITE_API_URL` points at the wrong place
+
+The frontend was built with a stale value. Rebuild the frontend. Option B: `docker compose up -d --build frontend`. Option A: restart `npm run dev`.
+
+### `alembic upgrade head` fails with "target database is not up to date"
+
+Your DB migration chain is out of sync with the code. On a dev box, the safe recovery is to drop the DB and re-migrate from scratch:
+
 ```bash
-free -h && swapon --show
+# Option A
+sudo -u postgres psql -c "DROP DATABASE resolutionflow;" -c "CREATE DATABASE resolutionflow;"
+cd backend && source venv/bin/activate && alembic upgrade head
+
+# Option B
+docker exec resolutionflow_postgres psql -U postgres -c "DROP DATABASE resolutionflow;" -c "CREATE DATABASE resolutionflow;"
+docker compose -f docker-compose.dev.yml run --rm backend alembic upgrade head
 ```
 
-### Check disk
+Only do this on a dev box — it destroys all local data.
+
+### `alembic heads` shows more than one head
+
+Only on a local branch that has diverged from `origin/main`. Production `main` has a single head. If this happens on a fresh clone, one of your local migration files has the wrong `down_revision`. Inspect each file's `down_revision` and reconnect the chain.
+
+### Frontend build fails with "EACCES: permission denied" on `dist/`
+
+Filesystem permission issue inside the code-server container (CLAUDE.md Lesson 105). TypeScript compilation itself completes — use `npx tsc -b` to verify cleanliness without needing to write to `dist/`.
+
+### Backend/frontend containers start but `/app` is empty (no code mounted)
+
+Almost always a `REPO_ROOT` problem. `docker-compose.dev.yml` uses `${REPO_ROOT}/backend:/app` and `${REPO_ROOT}/frontend:/app` bind mounts. If `REPO_ROOT` is unset, or set to a path that doesn't exist *on the Docker host* (not inside the code-server container), Docker silently creates an empty directory at that path and mounts it — the containers come up but have no source code. Symptom: backend returns import errors, or frontend serves a default Vite page. Fix: set `REPO_ROOT` in the repo-root `.env` to the absolute host-side path to the repo, then `docker compose down && docker compose up -d`. See 5.4 for the full note. This matters specifically when `docker compose` is invoked from inside a container (e.g. code-server with the host Docker socket mounted) — the CLI's CWD is container-local but the daemon resolves paths against the host filesystem.
+
+### Frontend shows "Blocked request. This host is not allowed" in the browser
+
+Vite 5+ ships DNS-rebinding protection that rejects any `Host:` header not in `server.allowedHosts`. The browser's hostname must be in that list. Edit `frontend/vite.config.ts` — the `server.allowedHosts` array should include every hostname you reach the dev server from (e.g. `'docker-01'`, `'localhost'`, `.ts.net` as a wildcard for Tailscale MagicDNS). Restart the Vite dev server (for Option B: `docker compose restart frontend`). This is unrelated to CORS — Vite blocks the request before any app code runs.
+
+### `docker` command not found inside code-server
+
+If your code-server is itself inside a container, Docker is probably not exposed to it. CLAUDE.md Lesson 103 was written for this case on the old VPS. On Proxmox, the fix depends on topology — either SSH to the host to run Docker commands, or mount the host's Docker socket into the code-server container.
+
+### Backend returns 500 with `InsufficientPrivilegeError: new row violates row-level security policy`
+
+RLS is enabled on a table your code wrote to without the right `account_id`. CLAUDE.md Lessons 107, 108, 110 cover this family of bugs. The fix is always at the service layer: make sure every model creation passes `account_id=` explicitly, and that startup routines that touch tenant-isolated tables use `_admin_session_factory()` rather than `get_db()`.
+
+### Anthropic cache reads are zero on the second turn
+
+Something in the cached prefix is changing between turns. Inspect the system-block list and the first N history messages for timestamps, `datetime.now()`, unsorted dict keys in JSON prompts, or varying tool-list order. The `anthropic.cache` telemetry shows exactly how many tokens were read vs created — use it to narrow down the invalidator.
+
+---
+
+## 9. Security posture for dev environments
+
+This doc is about dev, not production. But:
+
+- Never commit `.env` files. The `.gitignore` covers this.
+- `SECRET_KEY` should be generated per-host, not reused across environments.
+- `ANTHROPIC_API_KEY` is billable — rotate if leaked into logs or chat.
+- Postgres on a dev host should not be exposed to the internet. Bind it to `127.0.0.1` or to a private network interface only.
+- If you expose the frontend or backend publicly (for teammates to test against), put it behind TLS with a real certificate. Do not let dev credentials travel over plain HTTP on the public internet.
+
+---
+
+## 10. What's not in this doc
+
+- **Production deployment.** This is a dev-env doc. Production lives on Railway — see `CLAUDE.md`'s Deployment section.
+- **How to set up Traefik or any particular reverse proxy.** Whichever proxy you use is your choice; the dev stack just needs something that routes `<host>:5173` and `<host>:8000` to the right services. **Direct port exposure over a private network** (Tailscale, WireGuard, a VPN, or a LAN behind a firewall) is a fully supported option for dev and is what the homelab reference topology in Section 11 uses — no reverse proxy, no TLS, just `http://<host>:5173` and `http://<host>:8000` reachable only from the private network. That's a perfectly reasonable choice; it's just not the only one.
+- **How to configure code-server itself.** Install it however you prefer (native, Docker, LXC); point it at the repo, and the rest of this doc applies.
+- **Where to host the Proxmox instance.** Up to you.
+
+If something in this doc turns out to be wrong on your host, fix the doc. This is a living document — the whole point of rewriting it from the Hostinger-specific version was to make it survive host changes.
+
+---
+
+## 11. Reference topology: homelab Proxmox + code-server (Option B)
+
+This section documents the first concrete host instantiation since the April 2026 host-agnostic rewrite. It's a worked example, not the canonical topology — Section 3's Option A/B/C framing still stands. If your setup looks different, follow Sections 1–10 and ignore this appendix.
+
+### 11.1 Host
+
+- **Hypervisor:** Proxmox (homelab).
+- **VM:** `docker-01`, Debian 13, running Docker Engine + Docker Compose natively.
+- **Tailscale IP:** `100.64.78.44`. MagicDNS hostname: `docker-01` (and the full `.ts.net` FQDN).
+- **code-server:** runs on the same VM in its own container, with the host's Docker socket mounted in so it can drive `docker compose`. Its workspace bind-mounts the repo at `/opt/docker/code-server/workspace/resolutionflow`.
+
+This is a concrete instance of Option B from Section 3: Postgres, backend, and frontend all run as containers from `docker-compose.dev.yml`; the editor lives outside that compose network.
+
+### 11.2 Access pattern — direct port over Tailscale, no reverse proxy
+
+The browser reaches the dev stack directly:
+
+- Frontend: `http://docker-01:5173`
+- Backend: `http://docker-01:8000`
+- Backend API docs: `http://docker-01:8000/api/docs`
+
+There is **no Caddy, no Traefik, no nginx, no TLS, no basic auth** in front of either service. The tailnet provides the wire encryption and access control — only devices on the tailnet can resolve `docker-01` or reach `100.64.78.44`, and Tailscale ACLs decide which of those devices are allowed to connect.
+
+Why this choice:
+
+- **Zero routing config to maintain.** There is no proxy rulebook to keep in sync with new services. Add a container, expose a port, you're done.
+- **Backend-to-backend services stay private.** Redis, Celery workers, the planned ConnectWise proxy, the MCP server — none of them need to be reachable from the browser, so none of them need proxy rules. They stay inside the `resolutionflow` Docker network and talk by service name. The proxy would only ever have carried frontend and backend traffic, so the proxy's value was small relative to its maintenance cost.
+- **Debuggability.** `curl http://docker-01:8000/api/docs` from any tailnet device works without auth headers, TLS handshakes, or DNS shenanigans.
+
+Tradeoff: **this only works because every client device is on the tailnet.** If someone needed to test from a non-tailnet device, they'd either join the tailnet or we'd need to front the stack with a proxy. For the current single-developer setup, the tailnet-only assumption holds.
+
+### 11.3 Per-host config values (as actually configured on `docker-01`)
+
+Plugging these into Section 4's template:
+
+```
+DEV_HOST              = docker-01
+DEV_HOST_SCHEME       = http
+FRONTEND_PORT         = 5173
+BACKEND_PORT          = 8000
+POSTGRES_PORT         = 5433         # host-side; container-internal stays 5432
+POSTGRES_DB_NAME      = resolutionflow
+POSTGRES_USER         = postgres
+POSTGRES_PASSWORD     = postgres     # local-dev only
+SECRET_KEY            = <generated per host; do not reuse>
+ANTHROPIC_API_KEY     = <from console.anthropic.com>
+GOOGLE_AI_API_KEY     = <unset; Anthropic is sole provider in dev>
+```
+
+And the repo-root `.env` that `docker-compose.dev.yml` interpolates from:
+
 ```bash
-df -h
+SECRET_KEY=<redacted>
+ANTHROPIC_API_KEY=<redacted>
+POSTGRES_PORT=5433
+REPO_ROOT=/opt/docker/code-server/workspace/resolutionflow
 ```
 
-### Check memory + container usage
+### 11.4 Why `REPO_ROOT` is non-optional on this host
+
+code-server runs inside a container. When you open a terminal in code-server and run `docker compose -f docker-compose.dev.yml up -d`, the Docker CLI talks to the *host* daemon via the mounted socket — but the CWD it reports (`/config/workspace/resolutionflow`) is a path that only exists inside the code-server container. The host daemon has never heard of it.
+
+Relative bind mounts like `./backend:/app` therefore resolve against a path the host can't see, and Docker silently creates empty directories there rather than erroring out. The containers come up, but `/app` is empty.
+
+`docker-compose.dev.yml` sidesteps this by using `${REPO_ROOT}/backend:/app` and `${REPO_ROOT}/frontend:/app`. `REPO_ROOT` must be set to the absolute path **on the host** (`/opt/docker/code-server/workspace/resolutionflow`), not the path inside the code-server container. Same contents, different mount point, different name.
+
+If you ever run `docker compose` directly from a host shell (SSH'd into `docker-01`), set `REPO_ROOT` to `.` or the absolute host path. Being explicit is always safe; leaving it unset is the failure mode.
+
+### 11.5 Vite `server.allowedHosts` — required for `docker-01` to resolve
+
+Vite 5+ rejects any `Host:` header not in `server.allowedHosts` (DNS-rebinding protection). `frontend/vite.config.ts` has:
+
+```ts
+server: {
+  host: '0.0.0.0',
+  allowedHosts: ['docker-01', '.ts.net', 'localhost'],
+  ...
+}
+```
+
+- `docker-01` — the MagicDNS short name the browser uses day-to-day.
+- `.ts.net` — wildcard for the full Tailscale MagicDNS FQDN, in case anyone uses it.
+- `localhost` — for the "am I serving anything at all" smoke-test from inside the container.
+
+If you move this setup to a different host, add that host's hostname to `allowedHosts` or the browser will see "Blocked request. This host is not allowed." See Section 8's troubleshooting entry for the full symptom/fix.
+
+### 11.6 CORS origins on this host
+
+The `backend` service's `CORS_ORIGINS` environment variable is pinned in the compose file to:
+
+```
+["http://localhost:5173","http://127.0.0.1:5173","http://docker-01:5173","http://100.64.78.44:5173"]
+```
+
+The last two are what make browser calls from tailnet clients work — they cover both MagicDNS (`docker-01`) and the raw Tailscale IP. If you add a new hostname to reach the frontend from, also add the matching origin here and restart the backend.
+
+### 11.7 Compose file shape (as of this writing)
+
+`docker-compose.dev.yml` has been through a round of cleanup for this topology. Specifics worth knowing if you're comparing against older revisions of the file:
+
+- **No Traefik labels.** They were removed — nothing in this topology uses Traefik.
+- **No Hostinger-VPS-era origins** in `CORS_ORIGINS`.
+- `Dockerfile.dev` for both `backend` and `frontend` is still the build source — this didn't change.
+- Explicit `command:` directives on both `backend` (`uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload`) and `frontend` (`npm run dev -- --host 0.0.0.0 --port 5173`) — this guarantees `--host 0.0.0.0` regardless of what's baked into the image, so the services listen on all interfaces and are reachable from outside the container.
+- `REPO_ROOT` is interpolated into both service volume mounts (see 11.4).
+
+If you're adapting the file for a different host, the things most likely to need editing are `REPO_ROOT` (see 11.4), `CORS_ORIGINS` (see 11.6), `FRONTEND_URL`, `VITE_API_URL`, and `POSTGRES_PORT` if you want something other than `5433`.
+
+### 11.8 End-to-end sanity check for this topology
+
+From any device on the tailnet:
+
 ```bash
-free -h && docker stats --no-stream
+# Backend reachable
+curl -sSf http://docker-01:8000/api/docs >/dev/null && echo OK
+
+# Frontend reachable
+curl -sSf http://docker-01:5173 >/dev/null && echo OK
+
+# Alembic head matches the branch expectation
+docker exec resolutionflow_backend alembic current
+# expect f07010f17b01 on feat/flowpilot-migration, 074 on main
+
+# Postgres is alive inside the compose network
+docker exec resolutionflow_postgres psql -U postgres -d resolutionflow -c "SELECT now();"
 ```

-
-> **For the next Claude session:** Read this file completely, internalize the context, then delete it (`rm SESSION-HANDOFF.md`). This is a one-time context transfer.

-
-## What Was Done This Session
-
-### 1. FlowPilot Message Bar + AI Script Builder (MERGED to main)
-- PR #118 merged. Always-visible message bar in FlowPilot sessions, AI Script Builder at `/script-builder`, library reorg (My/Team Scripts tabs), FlowPilot-to-Script-Builder handoff, session abandon/close, unified session history.
-- Eng review completed: normalized `script_builder_messages` table, typed content helpers, 6 edge case tests.
-
-### 2. Design System v4 Migration (PR #119, open, branch: `refactor/design-system-v4`)
-- Complete frontend redesign from glassmorphism to flat dark theme (Sentry/PostHog-inspired)
-- **CSS Foundation:** New color tokens in `index.css`, all via CSS custom properties. Light mode ready (just needs `.light` class values).
-- **Icon Rail Sidebar:** 72px rail with 5 grouped icons (Home, Work, Knowledge, Insights, Help). Full-height resizable drawer on hover. Pin-to-expand to 260px. Mobile hamburger overlay.
-- **Component Sweep:** ~200 files migrated. All hardcoded hex replaced with semantic Tailwind tokens (bg-card, text-foreground, border-border, etc.).
-- **Landing Page:** Flat surfaces, no glow, solid buttons.
-- **Interactive Shadows:** Dark-mode-aware — elevated surfaces + faint cyan accent glow (black shadows invisible on dark bg).
-- **Stat Cards:** 3px colored left borders.
-- **Tab Toggles:** Active state uses `tab-active-shadow` (elevated bg + faint glow).
-
-### 3. GTM Strategy (from /office-hours)
-- Shadow & Ship approach: Michael uses ResolutionFlow on real tickets for 2 weeks, then hands logins to 5 MSP colleagues. Key metric: unprompted return.
-- Design doc at `~/.gstack/projects/patherly-patherly/`
-
----
-
-## What Needs To Be Done Next
-
-### Immediate (Design System v4 polish)
-1. **Home icon color fix:** The Home icon in the sidebar shouldn't have a cyan background when not active. Instead, the Home icon itself should always be cyan (brand accent), and only show the `bg-accent-dim` background when the route is actually `/`. Michael specifically requested this.
-2. **Visual QA pass:** Michael hasn't done a full page-by-page walkthrough yet. Expect feedback on individual pages once he does.
-3. **`font-label` cleanup:** ~10 files still reference `font-label` (deprecated alias for `font-mono`). Each needs inspection — some should be `font-mono`, others `font-sans text-xs`.
-4. **Inline `style` attributes:** ~29 instances still use hardcoded hex in inline styles (sidebar, drawer, badges). Should be converted to CSS variable references or Tailwind classes where possible.
-
-### Before Merging PR #119
-- Run migrations: `docker exec resolutionflow_backend alembic upgrade head` (new tables from the Script Builder PR are on main now)
-- Full visual QA with backend running
-- Test mobile responsive (hamburger menu)
-- Test FlowPilot session with new message bar + action bar positioning
-
-### Future
-- **Light mode toggle:** CSS variables are ready. Need to add `.light` class values in `index.css` + toggle in user settings/account page.
-- **Script Builder testing:** The AI Script Builder hasn't been tested end-to-end with the backend running yet.

-## Key Lessons From This Session
-
-- The component sweep agents missed `editor-ai/`, `guides/`, `maintenance/`, `scripts/`, `settings/` directories and `text-brand-dark` references. Always do a final grep audit after sweeps.
-- `bg-[#hex]` hardcoding defeats the purpose of CSS variables. We had to do a second pass to replace 3,200+ hardcoded values with semantic tokens.
-- Black shadows (`rgba(0,0,0,...)`) are invisible on dark backgrounds. Use elevated surfaces + faint accent glow instead.
-- The sidebar flyout needed `position: fixed` to escape the CSS Grid cell clipping — `absolute` positioning was hidden behind the main content area.
-- Flyout hover timing: individual item `onMouseLeave` was killing the flyout before the mouse reached the drawer. Only the outer wrapper should handle `onMouseLeave`.

+"""FlowPilot migration Phase 1 — schema for the unified session surface.
+
+Revision ID: f07010f17b01
+Revises: 074
+Create Date: 2026-04-17
+
+Creates the backing store for the FlowPilot unified session surface:
+
+- `session_facts` — "What we know" facts, keyed to a session, with a polymorphic
+  `source_ref` pointing at a task-lane item inside `ai_sessions.pending_task_lane`
+  (no DB-level FK; integrity enforced at the service layer per the design doc).
+- `session_suggested_fixes` — AI-proposed resolution paths. Only one active
+  (`superseded_at IS NULL`) per session at a time.
+- `draft_templates` — scripts pending post-resolve templatization
+  (Option 2 in the three-option dialog).
+- `account_settings` — new per-account key/value settings table with a JSONB
+  `preferences` grab-bag. Rows are created lazily on first write.
+- Column additions to `ai_sessions` — resolution/escalation markdown + external IDs,
+  plus `state_version` (incremented by any write that invalidates the resolution
+  note preview cache).
+- Column additions to `script_templates` — provenance fields for templates
+  promoted from draft_templates.
+
+All four new tenant-scoped tables have RLS enabled + forced with a
+`tenant_isolation` policy matching the repo pattern (USING + WITH CHECK on
+`account_id = app.current_account_id`). Downgrade is reversible: drops in the
+inverse order of creation.
+
+Chained from `074` (add_network_diagrams_table) per the single-head state of
+production; the other local heads on feat/flowpilot-migration are branch
+artifacts not present in production.

+## Prompt caching (Anthropic only)
+
+Callers may pass `system_prompt` as either:
+
+- `str` — backward-compatible, uncached.
+- `list[SystemBlock]` — Anthropic structured system blocks. Each block is a
+  dict of shape `{"type": "text", "text": str, "cache_control": {...}?}`.
+
+Caching policy (policy α, per Phase 0.1 design):
+- If any block in the list carries an explicit `cache_control` key, that
+  caller-authored configuration is honored verbatim.
+- If no block carries `cache_control`, the provider applies
+  `cache_control: {"type": "ephemeral"}` to the first block only. First block
+  is the common "large static prefix" case (e.g. system prompt, reference data).
+
+Gemini ignores cache_control and concatenates list blocks into one system
+string — callers should not rely on Gemini for cache-hit behavior.
+
+TODO(phase0-verify): When a dev environment is available, verify cache-hit
+behavior by hitting any FlowPilot endpoint twice within the 5-minute
+ephemeral TTL. First call should emit `anthropic.cache` with
+`cache_creation_input_tokens > 0`; second call with `cache_read_input_tokens > 0`.
+If the second call returns zero reads, inspect the prefix for silent

+## Promoting facts to "What we know"
+
+The engineer has a "What we know" panel that holds confirmed facts about this \
+session. Each confirmed fact stays visible to the engineer for the rest of the \
+session and feeds the resolution note posted to the customer ticket. Surface \
+facts there using a `[PROMOTE]` marker.
+
+**When to emit [PROMOTE]:**
+- The engineer just answered a [QUESTIONS] item with a substantive answer that \
+rules something in or out
+- The engineer just shared diagnostic-check output that confirmed a finding
+- You synthesized a new conclusion from two or more prior facts
+
+**When NOT to emit [PROMOTE]:**
+- The engineer's answer was "unknown", "I don't know", or a clarifying question \
+back to you
+- The diagnostic output was empty, errored, or inconclusive
+- You're re-stating something already in What we know
+- The "fact" is your own hypothesis, not something the engineer confirmed
+
+**[PROMOTE] marker format:**
+Each fact is its own block. You may emit multiple blocks per response.
+
+[PROMOTE]
+{"source_type": "question", "source_ref": "<task_lane_item_id>", "text": "<one short past-tense sentence stating what is now confirmed FROM THIS TICKET>", "summary": "<3-7 word provenance label specific to what the fact rules in/out>"}
+[/PROMOTE]
+
+- `source_type` is one of: `"question"` (fact derived from a question's answer), \
+`"diagnostic_check"` (fact derived from a check's output), or `"ai_synthesis"` \
+(you combined prior facts).
+- `source_ref` is the `id` field of the originating task-lane item — the \
+[QUESTIONS] and [ACTIONS] payloads you receive in conversation context include \
+an `id` for each item. Copy that UUID verbatim. For `ai_synthesis`, OMIT \
+`source_ref` (or set it to null).
+- `text` is a short past-tense sentence stating what's now confirmed. Use ONLY \
+information present in the engineer's CURRENT message — never invent specifics, \
+never reuse phrasing from past tickets or example payloads.
+- `summary` names the diagnostic value (what the fact rules in or out), 3-7 \
+words, no period.
+
+**Strict rule:** [PROMOTE] is for confirmed facts only. If you're not certain \
+the engineer's message confirms the fact, do not emit a [PROMOTE]. Hallucinated \
+facts get posted to customer tickets and will erode trust in the system.
+
+## Proposing a fix with [SUGGEST_FIX]
+
+When you have a concrete proposed resolution path with reasonable confidence, \
+emit a `[SUGGEST_FIX]` marker. This populates the "Suggested fix" card the \
+engineer can act on (run a script, build a template, etc.). A new \
+[SUGGEST_FIX] supersedes any prior suggested fix on the session — emit a fresh \
+one whenever your top hypothesis changes meaningfully.
+
+**When to emit [SUGGEST_FIX]:**
+- You have a concrete resolution path (not just "investigate further")
+- Confidence is at least ~50% — below that, keep diagnosing
+- Either a known Script Library template applies, OR you can draft a script \
+that resolves the issue end-to-end
+
+**When NOT to emit [SUGGEST_FIX]:**
+- You're still narrowing causes and the fix depends on the next answer
+- The "fix" is just running another diagnostic — that goes in [ACTIONS]
+- Two paths are equally likely — fork or ask first, suggest later
+
+**[SUGGEST_FIX] marker format (one block per response, last one wins).**
+Schema below — DO NOT copy these placeholders into your real response, fill \
+each field with content specific to the actual ticket:
+
+[SUGGEST_FIX]
+{"title": "<short imperative summary of the fix, ≤200 chars>", "description": "<one short paragraph: root cause + how the fix resolves it>", "confidence": <integer 0-100>, "script_template_slug": "<slug-of-existing-template-or-omit>"}
+[/SUGGEST_FIX]
+
+- `title`: short imperative summary, ≤ 200 chars
+- `description`: one short paragraph explaining the root cause and the fix
+- `confidence`: integer 0-100 (what you'd bet this resolves the ticket)
+- `script_template_slug`: slug of an existing Script Library template if one \
+applies; OMIT or set null otherwise
+- `ai_drafted_script`: full script body if no template matches (only when \
+`script_template_slug` is null/omitted)
+- `ai_drafted_parameters`: optional JSON object of suggested parameter values \
+for the drafted script
+
+The marker is stripped from display — the engineer sees the suggested fix as \
+an interactive card with confidence badge, not raw JSON.
+
+## Reporting fix outcome with [FIX_OUTCOME]
+
+When the engineer clearly indicates in chat that a previously proposed fix
+worked, didn't work, or was partially applied, emit a [FIX_OUTCOME] marker
+on its own lines. This surfaces a "confirm outcome?" banner in the UI — it
+does NOT mark the fix resolved on its own; the engineer confirms via the UI.
+
+**When to emit [FIX_OUTCOME]:**
+- The engineer states the user's problem is resolved after applying the fix
+  (affirmative resolution language → outcome="success")
+- The engineer states the issue persists after applying the fix
+  (→ outcome="failure")
+- The engineer describes applying only part of the fix
+  (→ outcome="partial")
+
+**When NOT to emit [FIX_OUTCOME]:**
+- The engineer is still verifying (user rebooting, testing, etc.)
+- The outcome is ambiguous or inferred rather than stated
+- No [SUGGEST_FIX] has been emitted this session
+
+**[FIX_OUTCOME] marker format (one block per response, on its own lines).**
+Schema below — DO NOT copy these placeholders into your real response, fill \
+each field with content specific to the actual ticket:

+- `outcome`: one of `"success"`, `"failure"`, or `"partial"`

+the active suggested fix, as given in the input bundle under "Outcome status":>
+
+- applied_failed: List the fix as a tried path. Include the failure reason if \
+provided. State that it did not resolve the issue.
+- applied_partial: Include the fix as a partially tried path. Include partial \
+notes if provided. Indicate it was not fully completed or not verified.
+- applied_success: Note that the fix was applied and verified but escalation \
+is still needed for another reason (unusual — reflect this accurately).
+- dismissed: Do not mention the fix as a tried path; it was only considered.
+- proposed (no outcome yet): Do not list it here; it goes in Current hypothesis.
+
+If nothing has been tried at all (no checks, no scripts, no applied/partial \
+fix), write "No diagnostic actions run yet." and continue.
+
+## Current hypothesis
+<The content depends on the outcome recorded for the active suggested fix:>
+
+- proposed (no outcome yet): State the fix title and confidence. If confidence \
+is below 60% or there is no active fix, say "No leading hypothesis yet — \
+symptoms are still being narrowed."
+- applied_failed or dismissed: Say the proposed fix did not hold or was set \
+aside. State any remaining uncertainty.
+- applied_partial: Note the partial application and what remains open.
+- applied_success: Unusual in an escalate path — state the fix resolved the \
+original symptom but a new or related issue requires escalation.

+## Suggested next steps
+<bulleted list of 2-4 concrete next actions the receiving engineer should \
+take. Prefer specifics: commands to run, tickets to check, people to contact. \
+Derive from the gap between confirmed facts and a complete resolution. \
+If the active suggested fix failed (applied_failed), inform the next steps \
+accordingly — e.g. suggest alternatives or deeper investigation paths, \
+drawing on the failure reason if provided. \
+If the fix is partially applied (applied_partial), the first step is typically \
+to complete or verify it. \
+If the fix is still proposed (no outcome), the first step is to try it if \

+"""FactSynthesisService — converts engineer answers and check output into facts.
+
+Two paths feed this service:
+
+1. **AI marker path (the common case).** When the model emits a `[PROMOTE]`
+   marker in the chat stream, `unified_chat_service` parses the marker (which
+   already contains the engineer-readable `text` and short provenance `summary`)
+   and calls `create_fact` directly. No LLM call is needed — the model already
+   wrote the fact.
+
+2. **Engineer-driven synthesize path.** The "+ Promote to What we know" affordance
+   in the UI sends a raw answer or check output and asks the server to draft
+   `text` + `summary` for review. `synthesize_from_question` /
+   `synthesize_from_check` make a small Haiku call for that draft. The engineer
+   confirms (or edits) before persistence, so the LLM output is never
+   silently posted to a customer ticket.
+
+Either way, persistence funnels through `create_fact`, which ALSO bumps
+`ai_sessions.state_version` so the resolution-note preview cache invalidates
+(see FLOWPILOT-MIGRATION.md Section 5.5).
+
+Model tier is `fact_synthesis` in `settings.ACTION_MODEL_MAP` (Haiku per
+Section 6.6). MCP is intentionally disabled for synthesis — these are
+pure transformations of input, not research calls.

+- `post_escalation_package` — same pattern for the Escalate flow.

+transition is a no-op and the endpoint response says so — we do not guess a

+You produce structured resolution notes for an MSP troubleshooting platform. \
+The notes are posted as ticket notes in the customer's PSA, so they must read \
+like a competent senior engineer summarized the work — not like an AI \
+narration. Your output goes in front of paying customers.
+
+Output exactly this markdown structure, no preamble, no closing remarks, no \
+extra headings:
+
+## Problem
+<one short paragraph stating the issue the engineer worked on, derived from the \
+session's intake/title and the incident header. Past tense. No "user reported" \
+hedging — state the problem directly.>
+
+## What we confirmed
+<bulleted list of facts from the "What we know" section, each one a short line. \
+Group similar facts together; do not invent connecting prose. If there are no \
+facts, write "Nothing was confirmed." and skip to Root cause.>
+
+## Root cause
+<one short paragraph naming the root cause based on the active suggested fix \
+and confirmed facts. If the suggested fix is low-confidence (<60%) or absent, \
+say "Root cause not definitively isolated." and explain what is suspected based \
+on facts.>
+
+## Resolution
+<The content of this section depends on the outcome recorded for the active \
+suggested fix, as given in the input bundle under "fix.status":>
+
+- applied_success: Write in past tense using closure language. State that the \
+fix was applied and verified as working. If verified_at is provided, you may \
+reference it as the time resolution was confirmed. Example phrasing: \
+"Applied <fix title>; confirmed working."
+- applied_failed: Acknowledge that the proposed fix did not resolve the issue \
+and was discarded. If failure_reason is provided, include it. Then describe \
+the actual resolution path taken (derived from facts and scripts run). This \
+state means the engineer resolved the issue another way; the note should cover \
+that actual resolution, not just the failed attempt.
+- applied_partial: Note that the fix was partially applied. If partial_notes \
+are provided, include them. Then describe the final resolution path taken.
+- dismissed: Treat the fix as considered and set aside. Do not center the note \
+on it. Describe the resolution based on what was actually confirmed and done.
+- proposed (no outcome yet): Write "Resolution not yet applied — fix proposed: \
+<fix title>." Pull verbatim script names and template references when available.
+
+Strict rules:
+- Use ONLY the facts and state I provide. Never invent specifics that are not \
+in the input.
+- Do not include placeholder text like "TBD", "TODO", or empty bullets.
+- Do not include the engineer's name, the AI's name, internal session IDs, or \
+the session's chat transcript.
+- Markdown headings exactly as shown (## level), no bolding the headings.
+- No trailing whitespace, no double-blank lines, no horizontal rules.

+"""TemplateExtractionService — propose a parameter schema from a rendered script.
+
+Phase 5 of the FlowPilot migration. Called when an engineer chooses
+"Run now, templatize after resolve" on a suggested fix with no existing
+library match. The service looks at the concrete script (with the values
+the engineer is about to run with) and session/ticket context, then
+proposes a parameterization that future engineers could use from the
+Script Library.
+
+Design choices (per FLOWPILOT-MIGRATION.md Section 6.4):
+
+- **Conservative by default.** Prefer fewer parameters. Environment-agnostic
+  values (like a command name) should not be parameterized. The prompt calls
+  that out explicitly.
+- **Round-trip check.** After the LLM proposes parameters, we validate that
+  the templated body renders back to the original script when given the
+  extracted parameter values. Failures log a warning and the caller falls
+  back to a single-parameter "raw script" proposal.
+- **Model:** Sonnet (`template_extraction` tier). Creates a persistent
+  library artifact — quality matters more than latency.
+
+Output shape mirrors the Script Generator's parameter schema:
+    {

+You are a senior MSP engineer drafting a reusable script template from a \

+parameterized with type=password.
+- The templated_body MUST render back to the original script when the \
+parameter values from the context are substituted in. Preserve all whitespace, \
+comments, and casing.
+- If the script has no meaningful parameters (e.g. it's a single read-only \

+Seed Phase 9 QA fixtures: 4 ai_sessions + matching suggested_fixes that
+exercise the five Phase 9 components which gate on a backend-emitted
+`SUGGEST_FIX` action and don't fire reliably in normal local sessions.
+
+Usage:
+  cd backend
+  python -m scripts.seed_phase9_qa_fixtures
+  python -m scripts.seed_phase9_qa_fixtures --reset   # delete & recreate
+
+Targets the super-admin from `seed_test_users.py`
+(admin@resolutionflow.example.com) and their account. UUIDs are
+deterministic (UUID5 over a fixed namespace) so re-runs are idempotent
+without --reset.
+
+Sessions created:
+
+| # | Title                           | Phase 9 component reached when…                       |

+| A | Phase 9 QA — no-template path   | ChatTabStrip + ScriptBuilderTab + ProposalBanner      |

+"""Guardrail: literal output payloads must not live in any LLM system prompt.
+
+This test exists because the same anti-pattern bit us twice in the same
+day: a worked example with literal content (Outlook + jsmith + literal
+JSON; full DNS troubleshooting tree) sitting inside a `*_PROMPT` constant
+caused Claude to recite that content on unrelated tickets, making the
+task lane look like it was leaking previous-session data.
+
+The fix is structural: every output example in a system prompt must use
+`<placeholder>` or `<...>` syntax, never literal field values, command
+names, hostnames, or usernames that the model could parrot. Format
+examples that need real-looking content live in few-shot messages
+(separate file, separate code path, model treats them as past behavior),
+not in system prompts.
+
+Failure messages here name the constant + line; fix by replacing the
+literal payload with a placeholder schema, or by moving the example
+out of the system prompt entirely.
+
+See CLAUDE.md → Critical Lessons → "Don't put literal payloads in
+system prompts" for the longer rationale.

+# FlowPilot & ResolutionAssist
+
+> ResolutionFlow offers two AI-driven troubleshooting modes that share the same session backend but present very different interaction styles. Both work standalone and become richer when paired with a PSA connection.
+
+---
+
+## At a glance
+
+| | **FlowPilot** | **ResolutionAssist** |
+|---|---|---|
+| **Style** | Guided, structured | Conversational, freeform |
+| **Entry** | `/pilot` | `/assistant` |
+| **Interaction** | Questions → Actions → Resolution, one step at a time | Natural chat with inline questions/actions |
+| **Best for** | Reproducible workflows, low-context engineers, handoffs | Exploratory problems, quick lookups, rubber-ducking |
+| **Lifecycle** | Active → Paused → Resolved / Escalated / Abandoned | Active → Resolved / Abandoned (lightweight) |
+| **Confidence tracking** | Yes — drives tier transitions | No — always responsive to user direction |
+| **Navigation guard** | Yes — prevents accidental loss | No — free to leave and return |
+
+Both modes share the `ai_sessions` table (discriminated by `session_type`), the same multimodal AI backend (image uploads, markdown, cached prompts), and the same `[QUESTIONS]` / `[ACTIONS]` / `[FORK]` marker vocabulary that renders inline TaskLane elements.
+
+---
+
+## FlowPilot — guided troubleshooting
+
+FlowPilot is a wizard-style AI engineer that walks you through a problem one diagnostic step at a time. It runs on confidence tiers:
+
+- **Discovery** (confidence < 0.4) — asking broad, open-ended questions to characterize the problem
+- **Exploring** (0.4–0.8) — proposing targeted actions and narrowing hypotheses
+- **Guided** (≥ 0.8) — recommending a specific fix with steps to verify
+
+### The FlowPilot session flow
+
+1. **Intake.** You start from `/pilot` or from the dashboard "New Session" button. The intake screen accepts free-text description, PSA ticket context, screenshots, or log pastes.
+2. **Preference check.** Before suggesting any fix, the AI asks whether you want a **GUI** or **script** approach. This is enforced in the system prompt so you never get steps you can't execute.
+3. **Step-by-step progression.** Each AI response is either a question (with clickable options), an action (with "Done" / "Didn't work" buttons), a `[FORK]` (two distinct paths to try), or a final resolution suggestion. You respond, the AI updates its confidence, and the next step is generated.
+4. **Action bar.** The session header always shows **Pause & Leave**, **Resolve**, **Escalate**, **Share Update**, and **Close**. Pausing freezes the session; resuming restores the full context.
+5. **Resolve / Escalate.** *Resolve* marks the ticket fixed and generates a clean summary of what worked. *Escalate* packages the problem summary and steps tried into an **escalation package** that the next engineer (or the PSA ticket) inherits.
+
+### Why FlowPilot exists
+
+- **New engineers** get senior-engineer-level diagnostic rigor without needing the experience to know what to ask next.
+- **Documented resolutions** — every step is captured, so the generated note on the ticket is substantive (not just "fixed it").
+- **Handoff-friendly** — escalation packages mean the next person doesn't start from zero.
+
+---
+
+## ResolutionAssist — conversational AI
+
+ResolutionAssist is a chat with an expert IT systems engineer. It's less structured than FlowPilot but still surfaces interactive elements when the AI wants structured input.
+
+### The ResolutionAssist flow
+
+1. **Open a chat.** From `/assistant` or the dashboard. Sessions show up in the left sidebar just like any messaging app.
+2. **Send a message.** Freeform prose. Attach up to 3 images per message (screenshots, error dialogs, network diagrams). Paste logs, code, or PowerShell output.
+3. **AI responds.** The response is prose, but any `[QUESTIONS]` or `[ACTIONS]` blocks render as a **TaskLane** — a side panel with clickable options and action buttons. You can answer via chat or click the TaskLane elements.
+4. **Branching (`[FORK]`).** If the AI proposes two paths ("check cable or restart switch?"), the fork renders as a choice. Picking one continues the conversation down that path.
+5. **Resume later.** Unlike FlowPilot, there's no navigation guard. Leave mid-conversation; every message is stored.
+
+### Why ResolutionAssist exists
+
+- **Unstructured problems** — "I have no idea where to start, here's a screenshot" works great.
+- **Reference lookups** — "what's the right PowerShell command to check Exchange health" is faster in chat than through an intake form.
+- **Senior engineers** — when you already know what you're doing and just want a second opinion or a syntax check.
+
+---
+
+## Without a PSA connection
+
+Both modes work standalone. Without ConnectWise connected:
+
+- Sessions live entirely in ResolutionFlow. They're listed in your session history, searchable, and shareable via public share links (`/shared/sessions/:token`).
+- Summaries generated on Resolve are saved to the session record but **not** written anywhere else. You can copy/paste into whatever ticketing or documentation system you use.
+- Escalating a FlowPilot session routes the escalation package to another ResolutionFlow engineer on your team — not to an external PSA ticket.
+- No ticket context is injected into the AI prompt, so the AI starts cold with only what you provide in the intake or first message.
+
+**Standalone use cases:**
+- Evaluating ResolutionFlow before committing to a PSA integration
+- Troubleshooting internal IT issues that aren't client-facing
+- Teams using a PSA ResolutionFlow doesn't integrate with yet
+- Knowledge-base research ("what are my options for X") that don't map to a ticket
+
+---
+
+## With a PSA connection (ConnectWise)
+
+When ConnectWise is connected, both modes become ticket-aware and write back to the PSA as a first-class client.
+
+### FlowPilot + PSA
+
+**Starting from a ticket:**
+- Click a ticket row (from `/tickets` or the dashboard queue) and pick "Start FlowPilot." The ticket's problem description, recent notes, configurations, company details, and related tickets are auto-injected into the AI's context. No manual retyping.
+- The session shows the linked ticket badge in the header.
+
+**During the session:**
+- **Share Update** — posts an interim note to the CW ticket with the current AI summary, so stakeholders can see progress without interrupting you.
+- **Status changes** — the detail panel and session header let you move the ticket through statuses (New → In Progress → Waiting on Customer → Resolved) directly from ResolutionFlow. Status writes are verified against CW so you're never told "success" when CW silently rejected the change.
+- **Resource assignment** — add yourself or a teammate as a co-assignee without touching the owner. If the ticket has no owner yet, assigning sets owner; if there's already an owner, you're added as an additional resource via a CW schedule entry.
+
+**On Resolve:**
+- Final summary is posted as a ticket note.
+- Ticket status can auto-update to Resolved (per your team's settings).
+
+**On Escalate:**
+- The escalation package (problem summary + steps tried) is posted as a note.
+- The ticket can be routed via CW's normal escalation rules.
+- The next engineer picking up the ticket can auto-start a new session with the full escalation context pre-filled.
+
+**Spin-off tickets (new):**
+- During any session, if you discover a separate issue, the AI can propose `create_spin_off_ticket`. Accepting opens the New Ticket modal pre-filled with the current ticket's company and board, so a second ticket is one click away without leaving your session.
+
+### ResolutionAssist + PSA
+
+**Starting from a ticket:**
+- Same ticket-context injection as FlowPilot. When opened with a linked ticket, the AI sees company, configs, notes, and related tickets.
+- A "New Ticket" button appears in the header — lets you spawn a separate ticket mid-conversation (same flow as FlowPilot's spin-off).
+
+**During the chat:**
+- Ask the AI about the ticket directly: *"Summarize what's been tried," "What configs does this company have?"* — the AI already has that context loaded.
+- `[ACTIONS]` can include `create_spin_off_ticket` when the AI detects a separate issue surfaced in the conversation.
+
+**Writing back:**
+- ResolutionAssist is a lighter-weight mode, so it doesn't auto-post on resolve. You can manually copy the conversation summary to a ticket note if useful.
+- Status updates and resource assignment are done via the `/tickets` page rather than the chat UI.
+
+---
+
+## Choosing between them
+
+| I want to… | Use |
+|---|---|
+| Walk through a known issue type with step-by-step rigor | **FlowPilot** |
+| Document every action taken for audit or handoff | **FlowPilot** |
+| Escalate with a full context package | **FlowPilot** |
+| Ask a question, get an answer, move on | **ResolutionAssist** |
+| Paste a screenshot and say "what's wrong here?" | **ResolutionAssist** |
+| Stay on the ticket for 2 minutes, not 20 | **ResolutionAssist** |
+| Troubleshoot without breaking flow to switch pages | Either, with the linked ticket panel open alongside |
+
+The two modes aren't competitive. A common workflow is to start in ResolutionAssist to scope the problem, then kick off a FlowPilot session when you realize the issue is going to take real diagnosis. Both show up in the unified session history.
+
+---
+
+## Tickets page — the PSA hub
+
+`/tickets` is the CW ticket manager built into ResolutionFlow. With a PSA connection:
+
+- Search and filter tickets by assignment (me / unassigned / specific member via searchable picker), board, status, priority, company, open/closed.
+- Slide-out detail panel shows notes, configurations, related tickets, and assignees — all fetched in parallel for fast hydration.
+- From the detail panel: change status, add/remove assignees, post notes, or "Start FlowPilot" / "Open in ResolutionAssist" with full context.
+- New Ticket modal offers both AI-parse ("Create a high-priority ticket for Acme — Outlook not syncing for jsmith") and a traditional form.
+
+Without a PSA connection, `/tickets` is hidden from the sidebar entirely — there's nothing to show.
+
+---
+
+## Summary
+
+- **FlowPilot** = guided, structured, lifecycle-heavy, ideal for resolvable issues and handoffs.
+- **ResolutionAssist** = freeform chat, ideal for scoping and quick answers.
+- **Without PSA** = both work, sessions live in ResolutionFlow, summaries are yours to export.
+- **With PSA** = both become ticket-aware, write back to CW (notes, status, resources), and can spawn spin-off tickets mid-session.
+
+The AI is the same under the hood. The difference is how much structure you want around the conversation — and how deeply the result needs to integrate with your ticketing system.

+# FlowPilot Migration Plan: Phase 0 Through Phase 7
+
+## Summary
+- Stay code-change-free until execution is explicitly requested.
+- Implement in commit-sized phases, with Phase 0 as a prerequisite for AI-heavy Phases 2+.
+- Use this repo’s existing `/api/v1/ai-sessions` API namespace instead of the doc’s generic `/sessions` path.
+- Move the existing chat-first `AssistantChatPage` to `/pilot`; `/assistant` becomes a permanent redirect.
+- Keep `ai_sessions.session_type` for compatibility, but the user-facing product becomes one FlowPilot surface.
+
+## Phase 0: Prompt Caching Infrastructure
+- Consolidate Anthropic prompt caching into `backend/app/core/ai_provider.py`, then route all Anthropic calls through that provider.
+- Preserve the existing cached behavior from `assistant_chat_service`, but remove the private duplicate cached implementation once provider parity exists.
+- Add cache-control blocks for static system prompt sections and stable tool/context prefixes; keep volatile user messages outside the cached prefix.
+- Update one-shot AI generators and `/tickets/ai-parse` to separate stable context from changing request content.
+- Instrument every Anthropic response with `cache_read_input_tokens` and `cache_creation_input_tokens`.
+- Acceptance: two identical FlowPilot/provider-backed calls within 5 minutes show creation tokens on the first call and read tokens on the second.
+
+## Phase 1: Schema + Route Rename
+- Add Alembic migration after current repo head with:
+  - `session_facts`
+  - `session_suggested_fixes`
+  - `draft_templates`
+  - `account_settings`
+  - new artifact columns on `ai_sessions`
+  - provenance columns on `script_templates`
+- Create `account_settings` as one lazy row per account:
+  - `account_id` primary key, FK to `accounts(id)` with cascade delete
+  - `preferences JSONB NOT NULL DEFAULT '{}'`
+  - timestamps
+  - `get_setting(key, default)` helper on the SQLAlchemy model
+  - `templatize_prompt_enabled` default read as `true` when the row/key is absent
+- Apply RLS to all new tenant-scoped tables using the repo’s `app.current_account_id` policy pattern.
+- Route `/pilot` and `/pilot/:sessionId` to the existing chat UI; redirect `/assistant` and `/assistant/:sessionId` permanently.
+- Update sidebar, command palette, dashboard cards, session list links, and visible labels from “AI Assistant”/ResolutionAssist to “FlowPilot” where they describe the troubleshooting surface.
+- Acceptance: `/pilot` renders the chat UI, `/assistant` redirects, RLS grep/check passes, and no Phase 2 UI is introduced yet.
+
+## Phase 2: What We Know
+- Add `FactSynthesisService` for conservative conversion of answers/check outputs into facts.
+- Add fact APIs under `/api/v1/ai-sessions/{id}/facts`:
+  - list, create manual note, update editable fact, soft-delete, promote source item.
+- Extend `unified_chat_service` marker parsing with `[PROMOTE]`; do not create a separate marker pipeline.
+- Because current questions/checks live in `ai_sessions.pending_task_lane` JSON, Phase 2 must assign stable UUIDs to task-lane questions/actions/checks when they are first persisted. `session_facts.source_ref` points to those stable JSON item IDs; it remains polymorphic and unconstrained at the DB level.
+- Add frontend task lane components under the new FlowPilot component namespace:
+  - `TaskLane`
+  - `WhatWeKnow`
+  - `WhatWeKnowItem`
+  - `AddNoteButton`
+  - moved/refactored Questions and Diagnostic Checks sections
+- Place What We Know above Questions. Facts from questions/checks are read-only at the fact card level; manual and AI-synthesis facts are editable.
+- Acceptance: answering a question or completing a check can promote a fact within 2 seconds; manual notes persist; page reload preserves facts; cross-account access is blocked.
+
+## Phase 3: Suggested Fix + Resolve Preview
+- Add suggested-fix APIs under `/api/v1/ai-sessions/{id}/suggested-fixes`:
+  - get active suggested fix
+  - record decision for one-off/draft-template/build-template/dismissed
+- Extend `unified_chat_service` marker parsing with `[SUGGEST_FIX]`; supersede the prior active fix when a new one is persisted.
+- Add `ResolutionNoteGeneratorService` that builds the fixed markdown shape:
+  - Problem
+  - What we confirmed
+  - Root cause
+  - Resolution
+- Add preview endpoint at `/api/v1/ai-sessions/{id}/resolution-note/preview`.
+- Generate the preview from `ai_sessions`, `session_facts`, active suggested fix, and linked script generations; redact sensitive script parameters.
+- Cache preview output by session-state version or content hash; invalidate on fact/suggested-fix/script-generation writes.
+- Add `SuggestedFix`, `ResolveButton`, and `ResolutionNotePreview` popover. Debounce preview refresh to 500ms.
+- Acceptance: a session with facts and a suggested fix shows a four-section preview; editing a fact refreshes preview; human review confirms no unsupported claims.
+
+## Phase 4: Resolve + Escalate Writebacks
+- Add `EscalationPackageGeneratorService` with handoff-oriented markdown:
+  - Problem
+  - What we’ve confirmed
+  - What we’ve tried
+  - Current hypothesis
+  - Suggested next steps
+- Add preview/post endpoints under `/api/v1/ai-sessions/{id}`:
+  - `/resolution-note/preview`
+  - `/resolution-note/post`
+  - `/escalation-package/preview`
+  - `/escalation-package/post`
+- Extend PSA writeback service using the existing PSA provider registry and `post_note` seam.
+- Implement “confirm and fire”: engineer edits preview, clicks Confirm & post, then server posts to PSA and stores result metadata.
+- Ticket status transitions must verify by re-fetching status; failed verification is surfaced as an error, not silent success.
+- Resolving without a linked PSA ticket stores markdown and marks the session resolved without external posting.
+- Acceptance: ConnectWise test ticket receives the note/package, status verification works, and unlinked sessions resolve locally.
+
+## Phase 5: Inline Script Generator Integration
+- Add inline Script Generator components:
+  - `TemplateMatchPanel`
+  - `NoTemplateDialog`
+  - `ParameterizationPreview`
+- For template matches, clicking the suggested fix opens the existing Script Generator flow with parameters prefilled from facts, ticket context, account/PSA config, and AI-suggested values.
+- For no-template matches, show the three-option dialog:
+  - Run as one-off
+  - Run now, templatize after resolve
+  - Build as template now
+- Persist the selected path on `session_suggested_fixes.user_decision`.
+- Add `TemplateExtractionService` for converting concrete scripts into proposed parameter schemas and templated bodies.
+- Link every script generation back to `ai_sessions` via existing `script_generations.ai_session_id`.
+- `Cmd+K → script` opens the inline generator from the FlowPilot session; no Resolve keyboard shortcut is added.
+- Acceptance: matched templates prefill parameters; no-match flow shows three options; all options produce the correct session/template side effects.
+
+## Phase 6: Post-Resolve Templatize Prompt
+- Add `TemplatizePrompt` after successful Resolve only when:
+  - the account setting allows prompts
+  - the session has pending `draft_templates`
+  - the user chose “Run now, templatize after resolve”
+- Accept flow creates a real `script_templates` row with:
+  - `source_session_id`
+  - `source_user_id`
+  - `source_ticket_ref`
+  - accepted parameter schema/body edits
+- Skip flow marks the draft rejected.
+- “Don’t ask me again for this team” writes `{"templatize_prompt_enabled": false}` to `account_settings.preferences`.
+- Script Library shows a pending-drafts badge/count for the account.
+- Acceptance: accept creates a visible template with provenance; skip creates no template; disabled prompt is respected on the next resolve.
+
+## Phase 7: Polish
+- Match the authoritative mockup HTML for spacing, colors, typography, and component structure; use PNGs for visual target confirmation.
+- Add loading states for fact synthesis, preview generation, template extraction, PSA post/verify, and script generation.
+- Add empty states for:
+  - no facts
+  - no questions
+  - no checks
+  - no suggested fix
+  - no pending draft templates
+- Add keyboard shortcuts except Resolve:
+  - `Cmd+K` command palette
+  - `Cmd+Enter` send composer
+  - `Cmd+G` script generator
+- At widths below 1200px, collapse the task lane into a bottom drawer.
+- Use existing design tokens where present; add missing tokens only if needed to match the mockups.
+- Acceptance: major screens visually compare within the doc’s tolerance, no horizontal scroll at 1280px, mobile task lane works, and shortcuts do not conflict with browser reload.
+
+## Public Interfaces
+- New backend routes use `/api/v1/ai-sessions/{id}/...`, not `/api/v1/sessions/{id}/...`.
+- Existing chat creation/message APIs remain compatible.
+- `session_type` remains queryable and stored, but frontend routing no longer sends chat sessions to `/assistant`.
+- New persistent entities:
+  - `session_facts`
+  - `session_suggested_fixes`
+  - `draft_templates`
+  - `account_settings`
+- New persisted artifact columns on `ai_sessions` store resolution/escalation markdown and PSA post metadata.
+
+## Test Plan
+- Migration tests:
+  - fresh DB upgrade succeeds
+  - downgrade succeeds if the repo expects reversible migrations
+  - new tables have RLS enabled/forced
+  - tenant policy includes `app.current_account_id`
+- Backend tests:
+  - fact CRUD and promotion authorization
+  - suggested-fix supersession and decision persistence
+  - preview generation cache invalidation
+  - Resolve/Escalate local-only behavior without PSA
+  - PSA status verification failure path
+  - draft-template accept/reject behavior
+- Frontend tests:
+  - route redirects
+  - task lane rendering and persistence
+  - inline editing and preview refresh
+  - script generator option flows
+  - templatize prompt settings behavior
+  - responsive drawer behavior
+- Manual QA:
+  - run through one ConnectWise linked Resolve
+  - run through one Escalate
+  - run one template-match script path
+  - run one no-template draft-template path through post-resolve save
+
+## Assumptions
+- Phase 0 is included and must be complete before Phase 2 begins.
+- No Resolve keyboard shortcut in this migration.
+- Templatize prompt defaults to enabled.
+- Resolution notes use engineer review plus Confirm & post, not supervisor staging.
+- Existing component folders may be renamed opportunistically, but behavior and route migration matter more than directory-name purity.
+- No backfill of What We Know for old sessions.
+- Team Wiki compilation, SharePoint integration, marketplace sharing, and confidence-tier UI are out of scope.

+# FlowPilot Migration — Design & Implementation Doc
+
+> **Target:** Transform `/assistant` (ResolutionAssist) into the new unified `/pilot` (FlowPilot) surface.
+> **Audience:** Claude Code (implementation) reviewed by Michael (owner).
+> **Status:** Design locked. Ready for phased implementation.
+> **Last updated:** April 17, 2026
+
+---
+
+## 0. Prerequisite reading for Claude Code
+
+Before writing any code, read these in order:
+
+1. This document end-to-end.
+2. `mockups/01-session-primary.png` — the target state for the main session UI.
+3. `mockups/02-script-template-match.png`, `03-script-three-options.png`, `04-script-templatize-prompt.png` — Script Generator integration states.
+4. The source HTML files `mockups/01-session-primary.html` and `mockups/02-04-script-integration.html` — authoritative for spacing, colors, and component structure. When CSS or layout questions arise during implementation, these files are the tiebreaker.
+
+Do not proceed to implementation until you have confirmed you understand the following three architectural claims. If any of them are unclear, stop and ask.
+
+1. **There is one AI troubleshooting surface, not two.** The existing split between FlowPilot (guided) and ResolutionAssist (chat) is collapsed into a single chat-primary product called FlowPilot at `/pilot`. The `ai_sessions.session_type` discriminator column is retained for data, but the product shows one unified UI.
+2. **The task lane is the load-bearing structural feature.** It is not a sidebar of metadata. It actively tracks diagnostic state: *What we know*, *Questions*, *Diagnostic checks*, *Suggested fix*. Engineers interact with it; facts flow between sections.
+3. **Resolve and Escalate are deterministic artifact generators, not free-text prompts.** When an engineer clicks Resolve, a structured summary is generated from task lane state (not from the chat transcript alone) and posted to CW. The summary structure is fixed: *Problem / What we confirmed / Root cause / Resolution*.
+
+---
+
+## 1. Why this change
+
+### The current state
+
+- `/assistant` is a chat-primary AI session with a `[QUESTIONS]` and `[DIAGNOSTIC_CHECKS]` task lane.
+- `/pilot` was specced as a separate guided, confidence-tiered wizard with a different UI and lifecycle.
+- The `FLOWPILOT-AND-RESOLUTIONASSIST.md` design document treated them as two products sharing a backend.
+
+### The problems with the current state
+
+- Two sidebar entries, two session histories, two mental models for engineers to learn.
+- The PSA integration scope doubles (writebacks for lifecycle events must be built twice, or built for Pilot and bolted onto Assist).
+- The Team Wiki moat depends on structured session artifacts with explicit resolutions — a chat-only mode produces weaker artifacts.
+- The cockpit positioning (the core ResolutionFlow brand promise) does not map to a blank chat window.
+- Branching into two modes forces a decision onto the engineer ("which mode for this ticket?") that has no right answer.
+
+### The resolution
+
+The existing `/assistant` UI already does most of what `/pilot` was supposed to do — structured questions, diagnostic checks, lifecycle actions in the header. It is closer to the right product than the doc anticipated. Rather than building Pilot as a second surface, we extend Assist with the missing structural features (*What we know*, auto-generated summaries, escalation packages) and rename it FlowPilot.
+
+### The strategic move
+
+FlowPilot becomes the single canonical troubleshooting surface. Every PSA writeback, every Wiki compilation path, every Script Generator invocation points here. One session shape, one lifecycle, one integration surface.
+
+---
+
+## 2. Terminology used in this document
+
+| Term | Meaning |
+|---|---|
+| **Session** | A single `ai_sessions` row representing one troubleshooting conversation. |
+| **Task lane** | The right-side panel containing What we know, Questions, Diagnostic checks, Suggested fix. |
+| **Fact** | An item in the What we know section. Has `text`, `source_type` (`question` / `diagnostic_check` / `user_note`), and `source_ref` (FK to the originating question/check, or null for user notes). |
+| **Suggested fix** | The AI's current best-guess resolution path. Has a confidence score and, optionally, a reference to a Script Library template. |
+| **Promotion** | The act of a question answer or diagnostic check result being converted into a fact in What we know. Triggered by AI, confirmed/editable by engineer. |
+| **Resolution note** | The structured document generated when the engineer clicks Resolve. Posted to CW as a ticket note. |
+| **Escalation package** | The structured handoff document generated when the engineer clicks Escalate. Posted to CW and attached to the session for the next engineer. |
+
+---
+
+## 3. Target UI — annotated
+
+### 3.1 Primary session view
+
+![Primary session view](mockups/01-session-primary.png)
+
+The session UI is a four-column layout:
+
+1. **Icon rail** (64px wide) — primary app navigation. FlowPilot / Tickets / Trees / Scripts / Wiki. Avatar at bottom.
+2. **Session list** (260px wide) — all sessions grouped by state (Active / Recent). Each row shows title, state dot, PSA ticket number, and client name.
+3. **Conversation column** (fluid) — the chat thread, composer, and incident header.
+4. **Task lane** (380px wide) — *What we know*, *Questions*, *Diagnostic checks*, *Suggested fix*, and the Resolve action at the bottom.
+
+Key visual and behavioral elements numbered against the mockup:
+
+**Incident header (top of conversation column)**
+- PSA chip showing `CW #48291` in cyan, monospaced
+- Client / contact / priority meta line
+- Incident title in Bricolage Grotesque 19px
+- Four lifecycle buttons right-aligned: **Pause** (ghost), **Share update** (neutral), **Escalate** (amber), **Resolve** (green)
+
+**Conversation column**
+- Standard chat thread with pilot and user avatars
+- Pilot uses cyan gradient avatar; user uses purple gradient
+- AI messages in `bg-2` bubbles with subtle border; user messages in cyan-tinted bubbles
+- Composer at bottom with inline action chips (Attach / Paste logs / Ticket context) and a send button
+
+**Task lane sections, in order:**
+
+1. **What we know** (NEW)
+   - Header: `WHAT WE KNOW · 4` (section title + count)
+   - Each fact is a card: `bg-2` background, dashed circular green check, fact text, and a provenance line (`from question · rules out tenant/license`)
+   - "+ Add a note" button at the bottom for manual facts from the engineer
+   - Background has a subtle green-to-transparent gradient to visually distinguish from the rest of the lane
+
+2. **Questions**
+   - Header: `QUESTIONS · 2 unanswered`
+   - Each unanswered question: title, AI hint text, Answer / Skip buttons
+   - Answered questions dim to 55% opacity with a dashed border and show the resolution inline (`Answered · isolated to jsmith (promoted to What we know)`)
+
+3. **Diagnostic checks**
+   - Header: `DIAGNOSTIC CHECKS · 1 / 3 run`
+   - "Run remaining 2 checks" button at top when applicable
+   - Each check: icon + command name (monospaced), description
+   - Completed checks dim and show "Complete · findings promoted to What we know" in green
+
+4. **Suggested fix**
+   - Header: `SUGGESTED FIX · 94% confidence`
+   - Amber-accented card with fix title and description
+   - Clicking opens the Script Generator flow (Section 5)
+
+**Resolve action bar (bottom of task lane)**
+- Small hint text ("Summary preview is open →")
+- Full-width "Resolve & post to CW" button in green
+
+**Resolution note preview (floating, anchored to Resolve button)**
+- A persistent popover, NOT a modal
+- Shows the draft resolution note with Problem / What we confirmed / Root cause / Resolution sections
+- Displays the target ticket (`CW #48291`) and status change (`Resolved`)
+- Edit button opens an inline editor; Confirm & post fires the PSA writeback
+
+### 3.2 Script Generator integration — template match
+
+![Template match flow](mockups/02-script-template-match.png)
+
+When the suggested fix references an existing Script Library template, clicking the fix opens the Script Generator panel in place of (or sliding over) the task lane. Key behavior:
+
+- A **Verified template** badge appears above the parameter form
+- Parameters pre-filled from session context get a cyan `from session` tag and a cyan-tinted input background
+- Each pre-filled parameter has a hint line explaining the source: *"Pulled from CW company config for Acme Corp"*
+- The engineer can adjust any pre-filled value before generating
+- `⌘K` → "script" invokes the generator mid-conversation from anywhere in the session
+
+### 3.3 Script Generator integration — no template match (three-option dialog)
+
+![No template match](mockups/03-script-three-options.png)
+
+When no template matches the suggested fix, FlowPilot drafts a session-specific script and presents three paths:
+
+1. **Run as one-off** (neutral outline CTA)
+   - Script generated and captured in session documentation, discarded after
+   - Tradeoffs: fastest, but team won't benefit next time
+
+2. **Run now, templatize after resolve** (RECOMMENDED, cyan primary CTA)
+   - Script generated for this ticket; draft template queued
+   - Post-resolve prompt offers to templatize (Section 5.3)
+   - Tradeoffs: zero cognitive overhead now, only templatize what works, ~30s review later
+
+3. **Build as template now** (purple outline CTA)
+   - Full parameterization upfront
+   - Tradeoffs: immediate team benefit, but adds time mid-ticket
+
+The drafted script renders as a code preview above the option cards with the AI's proposed parameters highlighted in amber.
+
+### 3.4 Script Generator integration — post-resolve templatization prompt
+
+![Templatize prompt](mockups/04-script-templatize-prompt.png)
+
+If the engineer picked Option 2 in the three-option dialog and Resolve succeeds, this prompt appears after the resolution note is posted to CW:
+
+- Success banner confirms the resolution posted
+- Templatize card shows the script with AI-proposed parameters substituted in as `{{ gateway_host }}`, etc.
+- Right pane lists extracted parameters with remove buttons (engineer can adjust)
+- Provenance note: *"generated from CW #48307 · resolved by M. Davis"*
+- Three actions: Skip / Edit parameters / Save as team template
+- "Don't ask me again for this team" opt-out in footer
+

+
+## 4. Data model changes
+
+### 4.1 New columns on `ai_sessions`
+
+```sql
+ALTER TABLE ai_sessions
+  ADD COLUMN resolution_note_markdown TEXT NULL,
+  ADD COLUMN resolution_note_posted_at TIMESTAMPTZ NULL,
+  ADD COLUMN resolution_note_external_id VARCHAR(128) NULL,  -- CW note ID after posting
+  ADD COLUMN escalation_package_markdown TEXT NULL,
+  ADD COLUMN escalation_package_posted_at TIMESTAMPTZ NULL;
+```
+
+No migration of `session_type` — the column stays. New sessions all default to the unified FlowPilot type.
+
+### 4.2 New `session_facts` table (the What we know backing store)
+
+```sql
+CREATE TABLE session_facts (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  session_id UUID NOT NULL REFERENCES ai_sessions(id) ON DELETE CASCADE,
+  account_id UUID NOT NULL REFERENCES accounts(id),  -- for RLS, per multi-tenant architecture
+  text TEXT NOT NULL,
+  source_type VARCHAR(32) NOT NULL CHECK (source_type IN ('question', 'diagnostic_check', 'user_note', 'ai_synthesis')),
+  source_ref UUID NULL,  -- FK to session_questions.id or session_diagnostic_checks.id, null for user_note
+  source_summary TEXT NULL,  -- free-text provenance label, e.g. "rules out tenant/license"
+  created_by UUID NOT NULL REFERENCES users(id),
+  created_at TIMESTAMPTZ NOT NULL DEFAULT now(),
+  updated_at TIMESTAMPTZ NOT NULL DEFAULT now(),
+  deleted_at TIMESTAMPTZ NULL
+);
+CREATE INDEX idx_session_facts_session ON session_facts(session_id) WHERE deleted_at IS NULL;
+CREATE INDEX idx_session_facts_account ON session_facts(account_id);
+```
+
+**Important:** `source_ref` is a polymorphic FK and should NOT have a database-level FK constraint. Enforce integrity at the service layer.
+
+### 4.3 New `session_suggested_fixes` table
+
+```sql
+CREATE TABLE session_suggested_fixes (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  session_id UUID NOT NULL REFERENCES ai_sessions(id) ON DELETE CASCADE,
+  account_id UUID NOT NULL REFERENCES accounts(id),
+  title VARCHAR(200) NOT NULL,
+  description TEXT NOT NULL,
+  confidence_pct INTEGER NOT NULL CHECK (confidence_pct BETWEEN 0 AND 100),
+  script_template_id UUID NULL REFERENCES script_templates(id),  -- null if no template match
+  ai_drafted_script TEXT NULL,                                    -- populated if no template match
+  ai_drafted_parameters JSONB NULL,                               -- AI's proposed parameterization
+  user_decision VARCHAR(32) NULL CHECK (user_decision IN ('one_off', 'draft_template', 'build_template', 'dismissed')),
+  superseded_at TIMESTAMPTZ NULL,  -- set when a new suggestion replaces this one
+  created_at TIMESTAMPTZ NOT NULL DEFAULT now()
+);
+CREATE INDEX idx_session_suggested_fixes_session ON session_suggested_fixes(session_id) WHERE superseded_at IS NULL;
+```
+
+A session can have multiple suggested fixes over time as the AI's understanding evolves. Only one is active (superseded_at IS NULL) at a time.
+
+### 4.4 New `draft_templates` table
+
+Backing store for Option 2 in the three-option dialog — scripts generated during sessions that are pending templatization.
+
+```sql
+CREATE TABLE draft_templates (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  account_id UUID NOT NULL REFERENCES accounts(id),
+  source_session_id UUID NOT NULL REFERENCES ai_sessions(id),
+  source_user_id UUID NOT NULL REFERENCES users(id),
+  script_body TEXT NOT NULL,
+  proposed_parameters JSONB NOT NULL,  -- {"parameters": [{"key": "...", "label": "...", "type": "..."}]}
+  proposed_name VARCHAR(200) NULL,
+  proposed_category_id UUID NULL REFERENCES script_categories(id),
+  status VARCHAR(32) NOT NULL DEFAULT 'pending' CHECK (status IN ('pending', 'accepted', 'rejected')),
+  resolved_at TIMESTAMPTZ NULL,  -- when the user acted on the draft
+  promoted_template_id UUID NULL REFERENCES script_templates(id),  -- if accepted, the created template
+  created_at TIMESTAMPTZ NOT NULL DEFAULT now()
+);
+```
+
+Accepted draft templates produce a new `script_templates` row and record the source session for provenance display.
+
+### 4.5 Extension to `script_templates`
+
+```sql
+ALTER TABLE script_templates
+  ADD COLUMN source_session_id UUID NULL REFERENCES ai_sessions(id),
+  ADD COLUMN source_user_id UUID NULL REFERENCES users(id),
+  ADD COLUMN source_ticket_ref VARCHAR(64) NULL;  -- e.g. "CW #48307" for display
+```
+
+These fields power the provenance chip in the Script Library: *"generated from CW #48307 · resolved by M. Davis · used 7 times"*.
+
+### 4.6 Per-account settings
+
+```sql
+ALTER TABLE account_settings
+  ADD COLUMN templatize_prompt_enabled BOOLEAN NOT NULL DEFAULT true;
+```
+
+Controls whether the post-resolve templatize prompt appears. Toggleable from the prompt's footer ("Don't ask me again for this team") and from admin settings.
+
+---
+
+## 5. API endpoints
+
+All endpoints follow ResolutionFlow conventions: `/api/v1/` prefix, JWT auth, tenant-scoped via RLS.
+
+### 5.1 Session facts
+
+```
+GET    /api/v1/sessions/{id}/facts               List facts for a session (ordered by created_at ASC)
+POST   /api/v1/sessions/{id}/facts               Create a manual fact (user_note source_type)
+PATCH  /api/v1/sessions/{id}/facts/{fact_id}     Edit fact text or summary (only for user_note or AI-synthesized facts)
+DELETE /api/v1/sessions/{id}/facts/{fact_id}     Soft-delete
+POST   /api/v1/sessions/{id}/facts/promote       Promote a question answer or check result to a fact
+                                                 Body: { source_type, source_ref, proposed_text, proposed_summary }
+                                                 Returns the created fact. Used by the AI synthesis flow and
+                                                 by the engineer's explicit "promote to What we know" action.
+```
+
+### 5.2 Suggested fixes
+
+```
+GET    /api/v1/sessions/{id}/suggested-fixes/active     Returns the current active fix (superseded_at IS NULL) or 404
+POST   /api/v1/sessions/{id}/suggested-fixes/{fix_id}/decision
+                                                        Body: { decision: "one_off" | "draft_template" | "build_template" | "dismissed" }
+                                                        Records the user's path choice. Server-side side effects:
+                                                        - one_off: generates script via ScriptTemplateEngine, returns rendered script
+                                                        - draft_template: same as one_off, plus creates draft_templates row
+                                                        - build_template: redirects to full template creation flow
+                                                        - dismissed: marks fix as superseded
+```
+
+### 5.3 Draft templates (post-resolve flow)
+
+```
+GET    /api/v1/draft-templates                          List pending drafts for the current user's account
+                                                        (used by the Script Library "X scripts ready to review" notification)
+GET    /api/v1/draft-templates/{id}                     Get a single draft including its proposed parameterization
+POST   /api/v1/draft-templates/{id}/accept              Body: { name, category_id, parameters_schema, edits }
+                                                        Creates a new script_templates row with source_session_id set,
+                                                        sets draft status to 'accepted', returns the new template
+POST   /api/v1/draft-templates/{id}/reject              Sets status to 'rejected'
+```
+
+### 5.4 Resolution notes and escalation packages
+
+```
+POST   /api/v1/sessions/{id}/resolution-note/preview    Generates the draft resolution note from current session state
+                                                        WITHOUT posting. Returns { markdown, target_ticket_ref }.
+                                                        Called when the task lane renders and refreshed whenever
+                                                        facts/suggested fix change.
+POST   /api/v1/sessions/{id}/resolution-note/post       Body: { markdown }  (engineer-edited version)
+                                                        Posts to the linked PSA ticket, updates ticket status if configured,
+                                                        marks session resolved.
+POST   /api/v1/sessions/{id}/escalation-package/preview Same pattern for escalation
+POST   /api/v1/sessions/{id}/escalation-package/post    Posts and transitions session to escalated state
+```
+
+---
+
+## 6. Services to implement
+
+### 6.1 `FactSynthesisService` (new)
+
+**Location:** `services/fact_synthesis_service.py`
+
+**Purpose:** Converts question answers and diagnostic check results into candidate facts. Called by the AI pipeline when the LLM emits a `[PROMOTE]` marker, and by explicit engineer action.
+
+**Key methods:**
+- `synthesize_from_question(question_id: UUID, raw_answer: str) -> dict` — returns `{proposed_text, proposed_summary}` via LLM call. The summary is the short provenance label ("rules out tenant/license").
+- `synthesize_from_check(check_id: UUID, check_output: str) -> dict` — same pattern for diagnostic check output.
+- `create_fact(session_id, source_type, source_ref, text, summary, user_id) -> SessionFact` — persists the fact.
+
+**Prompt engineering note:** The synthesis prompt should be conservative — short, factual statements. Hallucinated specifics are a trust-killer. The prompt must explicitly instruct: *"Use only information present in the answer/output. If the answer does not contain a substantive fact, return null."*
+
+### 6.2 `ResolutionNoteGeneratorService` (new)
+
+**Location:** `services/resolution_note_generator.py`
+
+**Purpose:** Produces the structured resolution note markdown from session state.
+
+**Input:** session_id
+**Output:** `{markdown: str, target_ticket_ref: str | None}`
+
+**Template structure:**
+```markdown
+## Problem
+{ai-synthesized one-paragraph problem statement, pulling from session description + incident header}
+
+## What we confirmed
+{bulleted list of session_facts, grouped by source_type}
+
+## Root cause
+{ai-synthesized from the active suggested fix + facts}
+
+## Resolution
+{description of the fix applied, parameters used if a script ran, outcome}
+```
+
+The service pulls from four data sources: `ai_sessions`, `session_facts`, `session_suggested_fixes` (active), and `script_generations` (if scripts ran during the session). Passwords in script_generations.parameters_used must be redacted (already a Script Generator pattern per the existing plan).
+
+**Critical:** This service is called on every fact/suggestion change to keep the preview live. Cache aggressively — LLM calls for every keystroke will blow the budget. Invalidate the cache on any write to session_facts or session_suggested_fixes.
+
+### 6.3 `EscalationPackageGeneratorService` (new)
+
+**Location:** `services/escalation_package_generator.py`
+
+Same structure as ResolutionNoteGenerator but with a handoff-oriented template:
+
+```markdown
+## Problem
+...
+
+## What we've confirmed
+...
+
+## What we've tried
+{list of diagnostic_checks run with their outcomes, scripts generated}
+
+## Current hypothesis
+{active suggested fix description}
+
+## Suggested next steps
+{ai-synthesized from the gap between facts and a complete resolution}
+```
+
+### 6.4 `TemplateExtractionService` (new)
+
+**Location:** `services/template_extraction_service.py`
+
+**Purpose:** Given a concrete rendered script and session context, propose a parameterization.
+
+**Input:** `{script_body: str, session_context: dict, ticket_context: dict}`
+**Output:** `{parameters: [{key, label, type, inferred_from}], templated_body: str}`
+
+**Implementation approach:**
+- LLM call with a structured prompt: "Given this script that resolved a ticket, identify values that would change for a different invocation. Propose a parameter schema following the Script Generator conventions (text / password / select / boolean / multi_text / number / textarea)."
+- Post-process to ensure the proposed template renders back to the original script when given the extracted parameter values.
+- Conservative default: prefer fewer parameters. If a value looks environment-agnostic (e.g. a command name), don't parameterize it.
+
+This service is the engine behind Option 2 and Option 3 of the three-option dialog, and behind the post-resolve templatize prompt.
+
+### 6.5 Extend `PSAWritebackService` (existing)
+
+Add methods:
+- `post_resolution_note(session_id, markdown) -> {external_id, posted_at}`
+- `post_escalation_package(session_id, markdown) -> {external_id, posted_at}`
+- `transition_ticket_status(ticket_ref, new_status) -> {success, verified_status}`
+
+The `transition_ticket_status` method must verify the status change took effect (per the existing ConnectWise integration principle: "never told 'success' when CW silently rejected the change").
+
+### 6.6 Model selection per service
+
+Each AI-calling service must use a configurable model string from application settings, not a hardcoded model. Use these defaults:
+
+```python
+FACT_SYNTHESIS_MODEL = "claude-haiku-4-5-20251001"           # short transformation, latency-sensitive
+RESOLUTION_NOTE_MODEL = "claude-sonnet-4-6"                  # customer-facing artifact, quality matters
+ESCALATION_PACKAGE_MODEL = "claude-sonnet-4-6"               # same
+TEMPLATE_EXTRACTION_MODEL = "claude-sonnet-4-6"              # creates persistent library artifact
+MAIN_CONVERSATION_MODEL = "claude-sonnet-4-6"                # primary FlowPilot chat
+```
+
+Do not hardcode model strings at call sites. Every new service must read from settings with a service-specific key.
+
+**Instrumentation requirement:** log a `disputed_fact_rate` metric for fact synthesis — the percentage of AI-synthesized facts that engineers subsequently edit or delete. If this exceeds 10% over a 500-session window, escalate `FACT_SYNTHESIS_MODEL` to `claude-sonnet-4-6`. If under 5%, Haiku is performing correctly.
+
+Do not use Opus 4.7 for any of these services at current scale.
+

+
+## 7. Frontend components
+
+### 7.1 Routes to change
+
+| Current route | New route | Action |
+|---|---|---|
+| `/assistant` | `/pilot` | **Rename** the route. The existing page moves. `/assistant` permanently redirects to `/pilot` with no sunset date. |
+| `/pilot` (if it exists as a separate guided flow) | REMOVED | Collapse into the unified surface. |
+| `/pilot/session/:id` | `/pilot/session/:id` | No change (this is where the unified session UI lives) |
+
+Sidebar nav entry renames from "ResolutionAssist" to "FlowPilot" with the cockpit icon.
+
+### 7.2 New React components
+
+Under `src/components/pilot/`:
+
+```
+TaskLane.tsx                  -- The right-side panel, owns all four sections
+  sections/
+    WhatWeKnow.tsx            -- New component for the facts list
+    WhatWeKnowItem.tsx        -- Single fact card with provenance line
+    AddNoteButton.tsx         -- "+ Add a note" inline composer
+    Questions.tsx             -- Existing questions rendering (moved if already present)
+    DiagnosticChecks.tsx      -- Existing checks rendering (moved if already present)
+    SuggestedFix.tsx          -- New or refactored component for the suggested fix card
+ResolveButton.tsx             -- The Resolve CTA at the bottom of the task lane
+ResolutionNotePreview.tsx     -- Floating popover anchored to Resolve button
+EscalatePackagePreview.tsx    -- Same pattern for Escalate
+
+ScriptGenInline/              -- Script Generator embedded in session context
+  TemplateMatchPanel.tsx      -- Scene 1 mockup: template pre-filled
+  NoTemplateDialog.tsx        -- Scene 2 mockup: three-option dialog
+  TemplatizePrompt.tsx        -- Scene 3 mockup: post-resolve prompt
+  ParameterizationPreview.tsx -- Shared component: script with highlighted params
+```
+
+### 7.3 Component behavior contracts
+
+**`WhatWeKnowItem`**
+- Props: `{fact: SessionFact, onEdit, onDelete}`
+- Renders the fact text, a green checkmark, and the provenance line with source-type color coding
+- Clicking the fact text opens inline edit (only for `user_note` and `ai_synthesis` sources — question/check facts are read-only, edit the source instead)
+
+**`TaskLane`**
+- Subscribes to a session state hook that polls for fact / question / check / suggested-fix updates
+- On any state change, calls `POST /api/v1/sessions/{id}/resolution-note/preview` to refresh the ResolutionNotePreview
+- Debounce preview refresh to 500ms to avoid LLM spam
+
+**`NoTemplateDialog`** (three-option dialog)
+- Props: `{suggestedFix, onDecision}`
+- Renders the three cards with the middle (draft_template) marked as recommended
+- `onDecision` posts to `/api/v1/sessions/{id}/suggested-fixes/{fix_id}/decision` and either opens the Script Generator (one_off / draft_template) or navigates to full template creation (build_template)
+
+**`TemplatizePrompt`**
+- Rendered after successful Resolve when a draft template exists for the session
+- Fetches proposed parameters from the draft template record
+- Save button posts to `/api/v1/draft-templates/{id}/accept`
+
+---
+
+## 8. AI prompt changes
+
+The existing FlowPilot / ResolutionAssist system prompt needs updates to emit the new markers.
+
+### 8.1 New marker: `[PROMOTE]`
+
+Used to surface facts to What we know. Syntax:
+
+```
+[PROMOTE]
+source_type: question
+source_ref: {question_id}
+text: OWA login and send/receive confirmed working for jsmith
+summary: rules out tenant/license
+[/PROMOTE]
+```
+
+The AI should emit `[PROMOTE]` blocks in the same message that answers or processes a question/check, so the fact appears in What we know simultaneously with the chat acknowledgment.
+
+### 8.2 New marker: `[SUGGEST_FIX]`
+
+```
+[SUGGEST_FIX]
+title: Clear cached credentials + rebuild Outlook profile
+description: Stale cached credential in Credential Manager is holding the pre-reset token...
+confidence: 94
+script_template_slug: clear-outlook-credentials   # or omitted if no template match
+ai_drafted_script: |                              # only if no template match
+  # Generated by FlowPilot...
+  ...
+[/SUGGEST_FIX]
+```
+
+### 8.3 Removed markers
+
+The old `[FORK]` marker from the ResolutionAssist prompt is removed. Forks were a Guided-mode concept; in the unified model, they're replaced by Questions with mutually exclusive answer options.
+
+---
+
+## 9. Implementation phases
+
+Each phase ends with a git commit and verification step. Do not advance to the next phase until verification passes.
+
+### Phase 0 — Prompt caching infrastructure (prerequisite)
+
+A codebase audit revealed that prompt caching is only implemented in `assistant_chat_service.py` (the file being deprecated). Every other Anthropic API call site — including all of FlowPilot's 7 call sites through `AnthropicProvider` — is uncached. Phase 0 must land before Phase 2 starts because new services built in Phase 2 will inherit caching from `AnthropicProvider` automatically once it's fixed.
+
+**Deliverables:**
+
+- **0.1** Promote `AnthropicProvider.generate_json()` and `generate_text_stream()` in `ai_provider.py` to the cached pattern currently implemented in `assistant_chat_service.py:_call_anthropic_cached()`. Convert the `system` string parameter to a structured system block list with `cache_control: {"type": "ephemeral"}` on the static portion. Add a second breakpoint on the last history message. For the streaming variant, capture the final usage object via `get_final_message()`. Log `cache_read_input_tokens` and `cache_creation_input_tokens` on every response.
+- **0.2** Update `integrations.py:557` (`/tickets/ai-parse`) to move the members list and team-stable boards data into a cached system block.
+
+  > **Phase 0.2 — pending target endpoint.** The `/tickets/ai-parse` endpoint described in the original migration doc does not exist in the codebase as of this commit. When this endpoint is built, apply the cached-system-block pattern:
+  >
+  > ```python
+  > system_blocks = [
+  >     {"type": "text", "text": members_json, "cache_control": {"type": "ephemeral"}},
+  >     # cacheable: team-stable
+  >     {"type": "text", "text": boards_json, "cache_control": {"type": "ephemeral"}},
+  >     # cacheable: team-stable
+  >     {"type": "text", "text": engineer_description},
+  >     # uncached: per-request
+  > ]
+  > ```
+  >
+  > Remove this note when the endpoint is implemented and the pattern applied.
+- **0.3** Add `cache_control` to one-shot generators: `ai_tree_generator`, `kb_conversion`, `ai_fix`, `script_builder`. Same pattern as 0.1.
+- **0.4** Extract the caching logic from `assistant_chat_service.py:_call_anthropic_cached()` into `AnthropicProvider` and delete `_call_anthropic_cached`. `assistant_chat_service` should call the provider like every other service. This prevents two canonical implementations of the same pattern.
+
+**Verification:**
+
+- Hit any FlowPilot endpoint twice within 5 minutes. First call shows `cache_creation_input_tokens > 0`, second call shows `cache_read_input_tokens > 0`.
+- If the second call returns zero cache reads, inspect the prefix for silent invalidators (timestamps, unsorted JSON keys, varying tool list ordering). Fix before proceeding.
+
+```
+git commit -m "feat(ai): promote AnthropicProvider to cached pattern, consolidate caching implementation"
+```
+
+**Dependencies:**
+
+- Phase 1 (route rename and schema) can run in parallel with Phase 0.
+- Phase 2 (What we know) must not start until Phase 0 is complete and verified.
+
+### Phase 1 — Data model and route rename (backend + routing only)
+
+**Deliverables:**
+- Alembic migration creating `session_facts`, `session_suggested_fixes`, `draft_templates` tables and the column additions to `ai_sessions`, `script_templates`, `account_settings`
+- All tables include `account_id` and have RLS policies following the multi-tenant architecture (per existing project standard)
+- `/assistant` → `/pilot` route rename with permanent redirect (stays in place indefinitely; no sunset date)
+- Sidebar nav entry rename
+- No UI changes yet beyond the nav label
+
+**Verification:**
+- Run migration on a fresh dev database
+- Confirm RLS policies active via the existing CI grep check for `tenant_filter()`
+- Navigate to `/assistant` — should 301 to `/pilot`
+- Navigate to `/pilot` — should render the existing ResolutionAssist UI with the sidebar entry now reading "FlowPilot"
+
+```
+git commit -m "feat(pilot): rename /assistant to /pilot, add session_facts + suggested_fixes + draft_templates schema"
+```
+
+### Phase 2 — What we know (task lane + service + API)
+
+**Deliverables:**
+- `FactSynthesisService` and its LLM prompt
+- Fact CRUD API endpoints
+- `WhatWeKnow`, `WhatWeKnowItem`, `AddNoteButton` components
+- Task lane layout adjustment: What we know section renders above Questions
+- Counter in task lane header updates to `X / Y answered` format
+- AI prompt updated to emit `[PROMOTE]` markers; backend parses them and creates facts
+
+**Verification:**
+- Open a session, answer a question; within 2 seconds a fact should appear in What we know with correct provenance
+- Click "+ Add a note", type a manual fact, confirm it appears with `source_type: user_note`
+- Run a diagnostic check, confirm the check result promotes to a fact
+- Facts persist across page reloads
+- RLS: a user from a different account cannot read or write facts for this session
+
+```
+git commit -m "feat(pilot): add What we know section with fact synthesis"
+```
+
+### Phase 3 — Suggested fix + resolution note preview
+
+**Deliverables:**
+- `session_suggested_fixes` API endpoints and data flow
+- `SuggestedFix` component in the task lane
+- AI prompt updated to emit `[SUGGEST_FIX]` markers
+- `ResolutionNoteGeneratorService` and preview endpoint
+- `ResolutionNotePreview` floating popover anchored to Resolve button
+- Preview refreshes on fact / suggested-fix changes (debounced)
+
+**Verification:**
+- Session with ≥3 facts and an active suggested fix shows a populated Resolve preview
+- Editing a fact updates the preview within 1 second
+- Preview markdown renders correctly with all four sections (Problem / What we confirmed / Root cause / Resolution)
+- Preview contains no hallucinated information not present in session state (human review of 5 real-ish sessions)
+
+```
+git commit -m "feat(pilot): add suggested fix tracking and Resolve note preview"
+```
+
+### Phase 4 — Resolve and Escalate PSA writebacks
+
+**Deliverables:**
+- `transition_ticket_status` method with CW verification
+- `post_resolution_note` endpoint and CW integration
+- Resolve button fires: post note → transition status → mark session resolved → show templatize prompt (if applicable)
+- `EscalationPackageGeneratorService` and parallel flow for Escalate
+- Escalate button fires: post package → transition status → mark session escalated → route via CW rules
+
+**Verification:**
+- Complete a session end-to-end with a ConnectWise test instance
+- Click Resolve, edit the preview, confirm post — verify the note appears in CW and status changes to Resolved
+- Click Escalate on a different session — verify the package is posted and the ticket routes correctly
+- Attempt to Resolve without a linked PSA ticket — should mark the session resolved without erroring, note stored in `resolution_note_markdown` only
+
+```
+git commit -m "feat(pilot): wire Resolve and Escalate to ConnectWise writeback"
+```
+
+### Phase 5 — Script Generator inline integration
+
+**Deliverables:**
+- `ScriptGenInline/TemplateMatchPanel` — when suggested fix has `script_template_id`, clicking the fix opens this panel with pre-filled parameters from session context
+- Parameter pre-fill logic: pulls from session facts, ticket context (company configs), and AI-suggested values in the `[SUGGEST_FIX]` marker
+- `ScriptGenInline/NoTemplateDialog` — three-option dialog when no template match
+- User decision persisted on `session_suggested_fixes.user_decision`
+- `TemplateExtractionService` for generating parameterization proposals
+- Script generation flow produces a `script_generations` record linked to the session (existing Script Generator behavior)
+
+**Verification:**
+- Session with a template-matched suggested fix: clicking opens generator with ≥2 pre-filled parameters
+- Session with a custom script suggested fix: dialog appears with three options, script preview shows parameters highlighted
+- All three paths end correctly: one-off generates and closes, draft creates `draft_templates` row and generates, build_template opens full template creation
+- `⌘K` → "script" anywhere in a session opens the generator directly
+
+```
+git commit -m "feat(pilot): integrate Script Generator inline with suggested fixes"
+```
+
+### Phase 6 — Post-resolve templatize prompt
+
+**Deliverables:**
+- `TemplatizePrompt` component
+- Logic: after Resolve success, check for pending `draft_templates` rows for this session; if any, show the prompt
+- Accept flow creates a new `script_templates` row with `source_session_id`, `source_user_id`, `source_ticket_ref` set
+- "Don't ask me again" writes to `account_settings.templatize_prompt_enabled`
+- Script Library sidebar shows a small badge when `draft_templates` with `status='pending'` exist for the current user
+
+**Verification:**
+- Resolve a session where the engineer picked Option 2 — templatize prompt appears with AI-proposed parameters
+- Accept the prompt — new template appears in the Script Library with the provenance chip ("generated from CW #...")
+- Skip the prompt — draft marked rejected, Script Library shows no new template
+- Toggle "don't ask me again" — next session Resolve skips the prompt even with a pending draft
+
+```
+git commit -m "feat(pilot): add post-resolve templatize prompt for draft templates"
+```
+
+### Phase 7 — Polish
+
+**Deliverables:**
+- Visual polish against the mockup files (spacing, colors, animations)
+- Loading states for LLM calls (fact synthesis, preview generation, template extraction)
+- Empty states (new session with no facts yet, no active suggested fix, no draft templates pending)
+- Keyboard shortcuts: `⌘K` (command menu), `⌘↵` (send composer), `⌘G` (generator), `⌘R` (resolve with confirm)
+- Responsive behavior: task lane collapses on <1200px viewports into a bottom drawer
+
+**Verification:**
+- Compare each major screen side-by-side with the mockup PNG files — colors, spacing, typography within 5px / exact color match
+- All flows work on a 1280px viewport without horizontal scroll
+- Keyboard shortcuts documented in-app via `?` overlay
+
+```
+git commit -m "feat(pilot): visual polish and keyboard shortcuts"
+```
+

+
+## 10. Design system reference
+
+All components must use the existing ResolutionFlow design system. Pulling the key tokens from the mockup CSS for quick reference — these should already exist in your tokens file; if they don't, add them:
+
+```css
+/* Backgrounds */
+--bg-0: #070b12;          /* page background */
+--bg-1: #0d131c;          /* sidebar / chrome */
+--bg-2: #121a25;          /* card / bubble background */
+--bg-3: #1a2332;          /* raised element */
+
+/* Borders */
+--border: rgba(148, 163, 184, 0.12);
+--border-strong: rgba(148, 163, 184, 0.22);
+
+/* Text */
+--text-primary: #e2e8f0;
+--text-secondary: #94a3b8;
+--text-tertiary: #64748b;
+
+/* Brand cyan (FlowPilot accent) */
+--cyan-400: #22d3ee;
+--cyan-500: #06b6d4;
+--cyan-600: #0891b2;
+--cyan-bg: rgba(34, 211, 238, 0.10);
+--cyan-border: rgba(34, 211, 238, 0.30);
+
+/* Semantic */
+--success: #34d399;   /* Resolve, facts */
+--warning: #fbbf24;   /* Escalate, proposed parameters */
+--danger:  #f87171;
+--purple:  #a78bfa;   /* Script Generator / templates */
+```
+
+**Typography:**
+- Body: IBM Plex Sans, 14px/1.5
+- Headings: Bricolage Grotesque, 500 weight, -0.01em letter-spacing
+- Code: JetBrains Mono
+
+**Icons:** Phosphor Icons (Duotone) per the memory-recorded design decision to migrate off Lucide.
+
+---
+
+## 11. Non-goals for this migration
+
+Do not build these as part of this work. They belong to later phases of the roadmap.
+
+- **Confidence tiers (Discovery / Exploring / Guided).** We explicitly removed these. The task lane itself is the progress signal.
+- **Mode toggle between Guided and Quick ask.** There is one mode.
+- **"Convert to guided" promotion flow.** No longer applicable.
+- **Team Wiki compilation from resolved sessions.** Tracked separately; depends on this migration but is not part of it.
+- **SharePoint integration.** Sequenced after ConnectWise per roadmap.
+- **Template marketplace / sharing across accounts.** Tracked under Client Context System roadmap item.
+
+---
+
+## 12. Risks and mitigations
+
+| Risk | Mitigation |
+|---|---|
+| LLM fact synthesis hallucinates specifics not in the answer | Conservative prompt; engineer can edit/delete any AI-synthesized fact; provenance line shows the source so the engineer can verify |
+| Resolution note preview LLM cost at scale | Cache aggressively, invalidate only on session state write; debounce UI updates to 500ms; consider lower-tier model for preview generation (final post-to-CW version can use the better model) |
+| ConnectWise silently rejects status change | `transition_ticket_status` must re-fetch and verify; fail loudly if the change didn't stick |
+| Template extraction proposes bad parameterization | Engineer reviews before saving; draft templates never silently become real templates; provenance chip lets team admins audit |
+| Users lose muscle memory from `/assistant` → `/pilot` rename | Permanent redirect (no sunset date); inline toast on first `/pilot` visit explaining the rename |
+| Existing sessions have no `session_facts` entries, so What we know is empty | Acceptable — Phase 2 deliberately does not backfill; facts only accumulate for new or ongoing sessions after deploy. Document in release notes. |
+
+---
+
+## 13. Questions for Michael before implementation starts
+
+These are the decisions Claude Code cannot make unilaterally. Answer these inline in the doc or in chat before kicking off Phase 1.
+
+1. **Keyboard shortcut for Resolve** — I've proposed `⌘R` (with a confirm). Browsers intercept `⌘R` for page reload. Alternative: `⌘⇧R` or no shortcut. Preference?
+2. **Default `templatize_prompt_enabled` value** — I defaulted to `true`. If your beta testers find it annoying we'll learn fast, but it's a tradeoff between "every engineer sees the prompt" and "feature gets discovered only by those who know about it".
+3. **Resolution note posts immediately, or stage for review?** — Current design: engineer edits preview inline, clicks Confirm & post. Alternative: stage in CW as draft note for a supervisor to approve before posting. Affects MSPs with strict compliance.

+# Phase 8 Review Issues
+
+Date: 2026-04-23
+
+Scope reviewed:
+- `backend/app/api/endpoints/session_suggested_fixes.py`
+- `backend/app/services/unified_chat_service.py`
+- `frontend/src/pages/AssistantChatPage.tsx`
+- `frontend/src/components/pilot/ProposalBanner.tsx`
+- `frontend/src/components/pilot/EscalateInterceptDialog.tsx`
+
+## 1. Outcome writes do not invalidate Resolve/Escalate preview cache
+
+Severity: High
+
+`PATCH /suggested-fixes/{fix_id}/outcome` updates the fix row but does not bump
+`ai_sessions.state_version`. Even after adding that bump, the preview input
+bundle also needs to include the fix outcome fields; otherwise a regenerated
+preview still cannot distinguish proposed, partially applied, failed, or
+successful fixes.
+
+Relevant files:
+- `backend/app/api/endpoints/session_suggested_fixes.py:226`
+- `backend/app/api/endpoints/session_suggested_fixes.py:146`
+- `backend/app/services/resolution_note_generator.py:13`
+- `backend/app/services/escalation_package_generator.py:14`
+
+Why this matters:
+- Resolve and Escalate previews are cached by `(session_id, state_version)`.
+- The decision endpoint already bumps `state_version`.
+- The new outcome endpoint does not.
+- A user can record `applied_success` / `applied_failed` / `applied_partial`
+  and still see markdown generated from the pre-outcome session state.
+- The preview generators currently pass only the active fix title,
+  confidence, description, and user decision into the LLM bundle. They do not
+  pass `status`, `applied_at`, `verified_at`, `partial_notes`, or
+  `failure_reason`.
+- Therefore a cache miss alone is not enough: the generated markdown may still
+  describe the fix as merely proposed because the outcome is absent from the
+  prompt input.
+
+Recommended fix:
+- Bump `AISession.state_version` inside the outcome endpoint transaction.
+- Include suggested-fix outcome state in both preview bundles:
+  - `status`
+  - `applied_at`
+  - `verified_at`
+  - `partial_notes`
+  - `failure_reason`
+- Update the resolution-note prompt expectations so `applied_success` produces
+  closure language, `applied_failed` states that the proposed fix did not
+  resolve the issue, and `applied_partial` includes the engineer's partial
+  notes.
+- Update the escalation-package prompt expectations so failed/partial outcomes
+  appear under "What we've tried" and inform "Suggested next steps."
+- Add a test proving a preview generated before an outcome change is
+  invalidated after the outcome patch and that the regenerated preview input
+  includes the recorded outcome.
+
+## 2. "Apply" is not persisted, so Verifying state is lost on reload/reselect
+
+Severity: High
+
+Phase 8 introduces a Verifying lifecycle in the UI, but clicking Apply only
+sets local React state.
+
+Relevant files:
+- `frontend/src/pages/AssistantChatPage.tsx:142`
+- `frontend/src/pages/AssistantChatPage.tsx:516`
+- `backend/app/api/endpoints/session_suggested_fixes.py:276`
+
+Why this matters:
+- `bannerApplied` is a client-side-only flag.
+- `handleApplyFix()` opens the script panel and flips local state, but does not
+  persist anything.
+- `applied_at` is only stamped later when an outcome is patched.
+- After refresh, chat reselect, or multi-tab use, a fix that had entered
+  Verifying falls back to `proposed`.
+- Nudge timing, resolve auto-success, and escalate interception therefore do
+  not survive normal session resume.
+
+Recommended fix:
+- Persist "apply started" as part of the fix lifecycle.
+- Either add an explicit backend transition for apply/start-verifying, or
+  persist `applied_at` when Apply is clicked.
+- Add a test or browser regression check covering refresh/reselect continuity.
+
+## 3. Rejecting an AI outcome proposal is only local and will reappear
+
+Severity: Medium
+
+Rejecting the AI-confirming banner clears `ai_outcome_proposal` only in local
+component state.
+
+Relevant files:
+- `frontend/src/pages/AssistantChatPage.tsx:571`
+- `frontend/src/pages/AssistantChatPage.tsx:431`
+
+Why this matters:
+- `handleRejectAIProposal()` only updates local `activeFix`.
+- The server-side `ai_outcome_proposal` remains unchanged.
+- The proposal comes back on the next `refreshSessionDerived()` call, which
+  happens after sends, task submissions, and chat selection.
+- "Not yet" is therefore a temporary hide, not a real rejection/correction.
+
+Recommended fix:
+- Add a backend way to clear or reject `ai_outcome_proposal`.
+- Make the reject action persist so the banner does not immediately re-arm on
+  the next refetch.
+
+## 4. Pre-existing failing decision test
+
+Severity: Low (test gap, no runtime regression)
+
+`tests/test_session_suggested_fixes_api.py::test_record_decision_persists_and_bumps_state_version`
+was authored in Phase 3 (`66e5920`) when the `decision` endpoint had no
+validation on `ai_drafted_script`. Phase 5 (`fa61376`) added a 400 guard:
+when the decision is `one_off`, `draft_template`, or `build_template` and the
+fix has no `ai_drafted_script` (and the caller provides no `edited_script` in
+the request body), the endpoint returns 400 with the message "Suggested fix has
+no ai_drafted_script — use /api/v1/scripts/generate for template-matched
+fixes."
+
+The test creates a fix without an `ai_drafted_script` and posts
+`{"decision": "draft_template"}` naked, so the guard fires and returns 400. The
+test still asserts 200. This was already broken before Phase 8 began — commit
+`cdd8bb0` (first Phase 8 commit) is 8 commits after `fa61376`.
+
+Root cause: test was never updated to match the Phase 5 contract change.
+
+Recommended fix for the next branch:
+- Option A (minimal): supply `ai_drafted_script="echo hello"` when creating the
+  fix fixture, or add `edited_script` to the POST body. Validates the happy path
+  for `draft_template` with a real drafted body.
+- Option B (comprehensive): add a separate test case asserting the 400 when
+  `ai_drafted_script` is null and no `edited_script` is provided, then fix the
+  existing test as in Option A. The 400-guard already has coverage in the
+  Phase 5 test file; the main gap is just the missing fixture update here.
+
+No Phase 8 code change required — this is a test-fixture gap from Phase 3/5
+drift, not a regression introduced in this branch.
+
+## Test Context
+
+Relevant backend suites were run serially from `backend/`:
+
+```bash
+pytest tests/test_fix_outcome_endpoint.py tests/test_fix_outcome_marker.py tests/test_session_suggested_fixes_api.py -q
+```
+
+Observed result:
+- `28 passed`
+- `1 failed`
+
+Remaining failure:
+- `tests/test_session_suggested_fixes_api.py::test_record_decision_persists_and_bumps_state_version`
+
+Notes:
+- That failing test is in the older decision-path suite and expects
+  `draft_template` to succeed without a drafted script.
+- The new outcome endpoint tests and marker parser tests passed in the serial
+  run.
+- The three issues above are based on code inspection and remain valid
+  regardless of that separate failing test.
+- Full root cause analysis documented in section 4 above.

+# Phase 9 Review Issues
+
+Date: 2026-04-24
+
+Scope reviewed:
+- `backend/app/api/endpoints/script_builder.py`
+- `backend/app/api/endpoints/session_suggested_fixes.py`
+- `backend/app/services/script_builder_service.py`
+- `frontend/src/pages/AssistantChatPage.tsx`
+- `frontend/src/components/pilot/ScriptBuilderTab.tsx`
+- `frontend/src/components/pilot/EscalateInterceptDialog.tsx`
+
+## 1. "Applied partially" from the escalation intercept cannot persist
+
+Severity: High
+
+The escalation intercept offers an "applied partially" choice, but the frontend
+sends `applied_partial` without notes. The backend requires notes for that
+outcome and returns 400. The frontend catches the error silently and still opens
+the conclude modal, so the user can believe the partial outcome was recorded
+when it was not.
+
+Relevant files:
+- `frontend/src/pages/AssistantChatPage.tsx:659`
+- `frontend/src/components/pilot/EscalateInterceptDialog.tsx:56`
+- `backend/app/api/endpoints/session_suggested_fixes.py:316`
+
+Why this matters:
+- `handleInterceptChoice()` maps the partial button directly to
+  `patchOutcome(..., "applied_partial")`.
+- The call does not provide `notes`.
+- `PATCH /suggested-fixes/{fix_id}/outcome` rejects `applied_partial` without
+  notes.
+- The catch block is silent and the UI continues into the conclude flow.
+- The recorded fix status therefore remains unchanged while the user sees a
+  flow that implies the partial outcome was accepted.
+
+Recommended fix:
+- Prompt for partial notes before calling `patchOutcome()` with
+  `applied_partial`.
+- Do not proceed to the conclude modal if the partial outcome write fails.
+- Consider hiding or disabling the partial option when it is not applicable, or
+  pass the current fix status into `EscalateInterceptDialog` so it can render
+  valid choices only.
+- Add a regression test covering the partial escalation-intercept path.
+
+## 2. Script Builder can attach stale script state to a newer active fix
+
+Severity: Medium/High
+
+`ScriptBuilderTab` keeps local builder state across active-fix changes within
+the same pilot chat. If a new active fix supersedes the previous one while the
+tab remains mounted, old messages, `latestScript`, or editor text can remain in
+memory while submission uses the new `fix.id`.
+
+Relevant files:
+- `frontend/src/components/pilot/ScriptBuilderTab.tsx:55`
+- `frontend/src/components/pilot/ScriptBuilderTab.tsx:78`
+- `frontend/src/components/pilot/ScriptBuilderTab.tsx:150`
+- `frontend/src/pages/AssistantChatPage.tsx:399`
+- `frontend/src/pages/AssistantChatPage.tsx:1630`
+
+Why this matters:
+- `ScriptBuilderTab` initializes `editorBuffer`, messages, and latest script
+  from props and builder-session data.
+- The create/resume effect depends on `pilotSessionId`, not `fix.id`.
+- `AssistantChatPage` detects active-fix changes but only closes the script
+  panel.
+- The rendered `ScriptBuilderTab` is not keyed by active fix id.
+- Submitting a stale builder draft calls the script patch endpoint with the
+  current `fix.id`, so an older script can be attached to a newer fix.
+
+Recommended fix:
+- Reset Script Builder local state when `activeFix.id` changes.
+- Key the rendered `ScriptBuilderTab` by `activeFix.id` if the intended UX is a
+  fresh builder surface per fix.
+- If inline builder conversations are intended to resume per fix, extend the
+  backend idempotency model to include the fix id instead of only
+  `(user_id, ai_session_id)`.
+- Add a frontend regression test for an active fix changing while the Script
+  Builder tab is mounted.
+
+## Review Context
+
+This review was based on code inspection of the latest committed Phase 9
+implementation. No tracked working-tree diffs were present at review time.
+
