-**Task:** Restore a fully green CI gate on `main` and lock it via branch protection so future merges can't introduce silent rot.
+**Active task:** Phase O cutover for self-serve signup. PR #164 (`feat/billing-plan-taxonomy`) open in Gitea with 5 commits at head `2c9f5e9`, closing the last code blockers — plan taxonomy reconciliation (`team` → `enterprise`, add `starter`), `INTERNAL_TESTER_EMAILS` allowlist, `sync_stripe_plan_ids.py` script, page-title `—` JSX-escape bug fix, frontend taxonomy followups, doc refresh. After merge, only manual ops remain: Stripe Dashboard live-mode config, Railway prod env vars, internal validation pass, public flag flip. See `.ai/HANDOFF.md` for the resume point.

+- **2026-05-08 — PR #164 (open)** Plan taxonomy reconciliation + `INTERNAL_TESTER_EMAILS` allowlist + Stripe sync script + page-title fix + frontend taxonomy followups + doc refresh. 5 commits on `feat/billing-plan-taxonomy` from main (`dad5e1f`); HEAD `2c9f5e9`. Migration `4ce3e594cb87` renames `plan_limits.plan='team'` → `'enterprise'` and adds `starter` row (caps interpolated between free and pro: `max_trees=10`, `sessions=75`, `ai=15/mo`). Resource visibility (`Tree.visibility='team'`, `StepLibrary.visibility='team'`) is a separate domain and intentionally untouched. New `backend/scripts/sync_stripe_plan_ids.py` upserts `plan_billing` rows from Stripe products by exact name match — annual fields stay NULL by design (user explicitly skipping annual pricing for exit flexibility). `Settings.is_internal_tester` + `is_self_serve_active_for` centralize the allowlist + global-flag check; new `get_current_user_optional` dep; `/config/public` honors allowlist for authenticated callers; `/auth/register` allows allowlisted emails without invite code. LandingPage page-title bug — `—` inside JSX attribute strings was rendering as 6 literal characters in browser tabs; replaced with literal em dash. PageMeta default tagline updated from "Decision Tree Platform" to "AI-Powered Troubleshooting for MSPs". 86/86 passing across subscription/billing/plan/invite/admin sweep; tsc + lint clean. See `.ai/DECISIONS.md` for the two architectural entries (taxonomy reconciliation, allowlist).
+- **2026-05-06 — PR #163** Seed test users marked email-verified. Squash-merged into main as `dad5e1f`.
+- **2026-05-06 — PR #162** Self-serve signup Phase 2 (frontend cutover). 18 commits across Tasks 27–44 of the plan. Backend remainders + frontend billing foundation + auth surfaces (OAuth + accept-invite + verify-email) + welcome wizard + dashboard redesign (TrialPill, NextStepCard, unified checklist) + public surfaces (`/pricing`, `/contact-sales`) + beta-signup deprecation. Squash-merged into main as `f1be3ab`. Single alembic head was `c6cbfc534fad` (no new migrations in Phase 2; PR #164 adds `4ce3e594cb87`).
+- **2026-05-02 — PR #159** In-product User Guides rewrite. Merged into `main`. Replaced 15 feature-dump guides with 43 problem-oriented Diátaxis how-tos grouped under 10 categories. Dropped Maintenance Flows / AI Assistant / Flow Assist Sparkles (UI no longer exists). Renamed Step Library → Solutions Library. Authored 14 net-new how-tos for FlowPilot-era surfaces (tasklane keyboard flow, what-we-know, resolve, escalate, record-fix-outcome, post-docs-to-ticket, share-update, pause-and-leave, build-script-from-scratch, open-suggested-flow, pin-a-flow, invite-teammate, etc.). Schema additions: `category`, optional `relatedSlugs`; hub renders category sections; detail page renders related-guides footer. Fixed rendering bug where `**bold**` in `step.tip` rendered literally. Killed misleading "N sections" subtitle on guide cards. Browser-verified against engineer + owner login (sidebar labels, account sub-pages, pilot-screen header buttons, Tasks panel, integration form). Two unverified items intentionally deferred: change-teammate-role (requires non-owner test member to inspect role-change control) and detailed Resolve / Escalate modal contents (Resolve gated by 6 pending tasks in test data). tsc and Vite build clean.
+- **2026-05-01 — PR #158** Session-screen UX impeccable pass + tasklane keyboard flow. Merged into `main` as `5e10005`.
+  - **Impeccable pass** (5 sub-passes — distill / quieter / layout / typeset / polish): score 24/40 → 33/40. Removed the duplicate "Suggested checks" chip strip; added an inline `Next steps · N pending in Tasks` cue above the latest action-bearing AI bubble; consolidated the desktop session header to Resolve + Escalate + ⋯ kebab (Context / New Ticket / Update Ticket / Pause now under the kebab, mobile kebab gained Context + New Ticket parity); centered the messages column to `max-w-3xl` to match the composer; bubbles dropped to `rounded-xl`. Decoration sweep: dropped 3px side stripes (TaskLane done states, all 6 ProposalBanner modes, WhatWeKnowItem rows), gradient backgrounds (WhatWeKnow + every banner), accent borderTop on TaskLane header, backdrop-blur on handoff overlay, animate-pulse-amber ring in VerifyingBanner, bordered avatar boxes in banners. Type sweep: 14 distinct sizes → 5-step scale (10/11/12/13/14px). Icon disambiguation: `MessageCircleQuestion` split into `Pencil` (Answer CTA) + `HelpCircle` (per-check explainer). Dead `font-sans` audit (12 sites) and double `text-xs` cleanups.
+  - **TaskLane keyboard-first flow** (real feature): Enter submits + auto-advances to next pending task, Shift+Enter newline, Esc cancels, focus jumps to Send Responses after the last submission. Mouse path also auto-advances. Subtle hint row teaches the shortcut.
+  - **Banner ↔ script panel linked**: collapsing or dismissing the ProposalBanner now also hides the InlineNoTemplateDialog / TemplateMatchPanel; recording any outcome closes both surfaces.
+  - **WhatWeKnow collapsible**: per-session preference in `sessionStorage` (`rf-whatweknow-collapsed:{sessionId}`); auto-collapses on first render at ≥5 facts.
+  - **Side fix**: `ParameterizationPreview.tokenize()` word-boundary guard prevents over-eager highlighting of short values like `"D"` (no longer lights up every capital D in `Get-ADUser`).
+  - Validation: tsc clean, ESLint clean, Vite build clean. Type-check + lint passed at every commit boundary.
+- **2026-05-01 — PR #156** Suggested-fix `applied_pending` non-terminal outcome. Merged into `main` as `3ba4532`. Adds:
+  - Schema/API: `FixStatus="applied_pending"`, `pending_reason` Text column, migration `c0f3a4b7e91d`. `PATCH /suggested-fixes/{id}/outcome` accepts pending, requires notes, stamps `applied_at` only.
+  - UI: `PendingBanner` (info-tone, worked / didn't / update reason / dismiss). "Waiting to verify…" overflow option in `VerifyingBanner`. Nudge "Still checking" records pending with a reason. Page-level Resolve auto-patches pending → success before resolution flow; page-level Escalate intercepts pending the same way verifying/partial does.
+  - Generators: `resolution_note_generator` and `escalation_package_generator` system prompts handle the new status without real-looking examples.
+  - Tests: 4 new in `test_fix_outcome_endpoint.py` (21/21 suite green); prompt anti-parrot guardrail green; tsc + Vite build clean.
+  - QA report: `.gstack/qa-reports/qa-report-pending-verification-2026-04-30.md` (5/7 scripted checks PASS with concrete evidence; 2 entry-path checks deferred — same handlers verified via tested transitions).
+- **2026-04-30 — PR #155** Escalation Mode wedge merged as `ac42f97`. Senior-tech magic-moment screen. Plan: [`docs/plans/2026-04-27-escalation-mode-wedge-design.md`](../docs/plans/2026-04-27-escalation-mode-wedge-design.md).
 
-**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`.
+## Two-metric framing (Escalation Mode — read before quoting numbers)
 
-**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.
+The in-product `GET /analytics/flowpilot/escalations` endpoint measures *post-claim time-to-first-action*. The "minutes recovered" sales claim is `manual_baseline − in_product_metric`. Manual baseline comes from the founder's stopwatch on the next 5 escalations. Don't roll the in-product number alone into "minutes recovered" — that's the apples-to-oranges miscount Codex caught.
+
+## Kill-switch (Escalation Mode)
+
+Week 8: if 0 of 3 pilots produce a verifiable hours-saved-per-week number above 1.0, revisit the wedge.
+
+## Notes for next session
+
+- Drive checks 1 (VerifyingBanner overflow → "Waiting to verify…") and 5 (nudge "Still checking" with 3+ post-apply messages) in real pilot usage to close the QA gap left by `/qa` (the tested handlers cover the same mutations, but the entry-path UI rendering wasn't exercised end-to-end).
+- Consider monitoring how often pending fixes get parked vs resolved — if engineers report losing track across sessions, revisit the cross-session "Follow-ups" dashboard rollup that was scoped out.
+- After PR #158 lands in real ticket flow, eyeball the keyboard-hint contrast and the WhatWeKnow auto-collapse-at-5 threshold — both were judgment calls (5 was a guess; the contrast bump from `/70` to full muted-foreground was based on my read, not real screen testing). Adjust if the 5-fact threshold feels too aggressive or too lenient mid-session.
+- Two follow-ups logged in `.ai/TODO.md` from the impeccable pass: `ConcludeSessionModal` paused/escalated step should allow multi-select (Ticket Notes + Client Update + Email Draft simultaneously) — real feature work; `bg-card-hover` Tailwind class doesn't resolve in `CommandPalette` — two-line fix.

+## 2026-05-07 — Per-email allowlist (`INTERNAL_TESTER_EMAILS`) for self-serve soft cutover
+
+**Context:** Phase O Task 46 ("internal validation pass") needed a way to exercise the full self-serve flow against the prod backend before flipping `SELF_SERVE_ENABLED=true` for everyone. The plan doc described the mechanism but the backend support was never built — flagged in `SESSION_LOG.md` as a code blocker. Stripe live-mode setup is also gated on having a working internal-tester path in prod test mode.
+
+**Decision:** Comma-separated allowlist `INTERNAL_TESTER_EMAILS` parsed by a Pydantic field_validator into a normalized lowercase list. Two helpers on `Settings`: `is_internal_tester(email)` (case-insensitive membership check) and `is_self_serve_active_for(email)` (returns `SELF_SERVE_ENABLED OR is_internal_tester(email)`). Both endpoints that gate on the global flag now call the helper:
+- `/config/public` accepts optional auth via new `get_current_user_optional` dep; returns `self_serve_enabled=true` for allowlisted authenticated callers; anonymous calls always see the global flag.
+- `/auth/register` allows allowlisted emails to register without an invite code.
+
+**Rejected:**
+- **Custom header `X-Internal-Tester-Email` for anonymous flows.** Spoofable. The auth/register-payload checks are sufficient because the user has to OWN the email to register or log in.
+- **Separate allowlists per surface (`INTERNAL_PRICING_TESTERS`, `INTERNAL_OAUTH_TESTERS`).** Premature splitting. The Phase O use case is "this small set of people can see the new flow"; one variable handles it. If finer granularity emerges, split then.
+- **Database table for the allowlist.** Env var matches the spec from the plan doc and fits the soft-cutover lifecycle — list is small, changes infrequently, lives alongside other deployment-time config.
+
+**Consequences:**
+- Stripe internal validation can run end-to-end in prod test mode without flipping the global flag.
+- Anonymous callers always see the global flag — the allowlist never leaks via unauthenticated request content. Three regression tests in `test_config_public.py` enforce this.
+- `INTERNAL_TESTER_EMAILS` plumbed through `docker-compose.dev.yml` and documented in `backend/.env.example`. Railway prod env will need the same var set during Phase O cutover.

+## 2026-05-07 — Reconcile plan tier taxonomy (rename `team` → `enterprise`, add `starter`)
+
+**Context:** PR #162 left a real architectural gap. Marketing surface (PricingPage, Stripe products) was wired for `Starter / Pro / Enterprise` while backend was on `free / pro / team`. `plan_billing.plan` FK referenced `plan_limits.plan` so the `BillingPlan` schema's `Literal["pro", "starter", "team", "enterprise"]` could accept values that violated the FK. `plan_billing` was unseeded in dev, so no checkout could complete. `Subscription.plan.in_(["pro", "team"])` paid-plan checks wouldn't recognize `enterprise`. Self-serve cutover was blocked at the data layer.
+
+**Decision:** Reconcile to a single taxonomy — backend slugs become `free / pro / starter / enterprise`, matching the marketing surface and Stripe products. Migration `4ce3e594cb87`:
+1. Defensive `UPDATE subscriptions SET plan='enterprise' WHERE plan='team'` (dev had zero such rows; safety for any prod stragglers).
+2. Rename the `plan_limits.plan='team'` row to `'enterprise'`.
+3. Insert a `starter` row with caps interpolated between free and pro: `max_trees=10`, `max_sessions=75`, `max_users=1`, `max_ai_builds_per_month=15`, no KB Accelerator, no custom branding, no priority support.
+
+Code rename across schemas, `Subscription` paid-plan/`has_pro_entitlement` checks, admin endpoints, frontend `useSubscription.isPaidPlan`. Resource visibility (`Tree.visibility='team'`, `StepLibrary.visibility='team'`) is a separate domain and intentionally untouched — that string means "shared with my account" and has nothing to do with the subscription tier.
+
+New `backend/scripts/sync_stripe_plan_ids.py` — idempotent upsert of `plan_billing` rows from Stripe products by exact name match (`ResolutionFlow Starter / Pro / Enterprise`). Picks the active monthly recurring price for tiers that have one. Annual fields stay NULL by design — annual pricing is intentionally out of scope for the soft cutover ("want to be able to exit if necessary without breaching any terms").
+
+**Rejected:**
+- **Map marketing names to existing slugs (Option A from the discussion).** Smallest diff but means PricingPage cards have to translate `enterprise` → `team` at render time, and "Starter" can't exist as a real backend tier — it'd have to be hidden or dropped. Kicks the can.
+- **Add `starter` only, keep `team` slug as cosmetic enterprise (Option C).** Mixed taxonomy across layers — slug-vs-display-name divergence guarantees confusion in 6 months. Compromise that's worse than either pure choice.
+- **Annual pricing in this iteration.** User's explicit constraint: skip annual to keep exit-flexibility. Schema columns (`annual_price_cents`, `stripe_annual_price_id`) preserved as nullable for future re-enable.
+- **Auto-archive the existing Enterprise `$500/mo` test-mode price.** Done manually via Stripe MCP after un-setting the product's `default_price` first. Spec says Enterprise is sales-led with no catalog price.
+
+**Consequences:**
+- `plan_billing` table is now seedable and seeded. Test-mode `plan_billing` populated for all 3 tiers via `sync_stripe_plan_ids.py`. Live mode runs the same script after manual Dashboard setup of products + prices.
+- New consumers of `Subscription.plan` literal must use `("free", "pro", "starter", "enterprise")`. Three call sites already updated. Backend-wide grep is the safety net for new ones.
+- `Subscription.is_paid` and `has_pro_entitlement` now include `starter` — Starter is a paid tier with a real $19.99/mo price.
+- 86/86 passing across the subscription/billing/plan/invite/admin sweep after the rename.
+- Test fixtures: `conftest.py` plan_limits seed updated to the new taxonomy. `_seed_plan_limits` helper in `test_plans_public.py` is now a true upsert so tests can override `max_users` even when conftest seeded the canonical value.

+## 2026-05-07 — Standardize backend Python on 3.12
+
+**Context:** Runtime facts had drifted from docs. The backend Dockerfiles and running dev container were already on Python 3.12, GitHub CI had just been updated to 3.12, but project docs still said Python 3.11 and Gitea CI relied on the runner's ambient Python.
+
+**Decision:** Treat Python 3.12 as the backend standard. Pin local pyenv via `.python-version` to 3.12.13, matching the current `python:3.12-slim` container patch level. Add explicit Python 3.12 setup to Gitea CI and keep GitHub CI on Python 3.12.
+
+**Rejected:** Moving Docker/runtime back to Python 3.11. The application was already building and running on 3.12, so reverting the runtime would add churn without a product or dependency reason.
+
+**Consequences:** Native backend work should use `backend/venv` created from Python 3.12.13. Future docs/CI/runtime changes should preserve Python 3.12 unless a deliberate upgrade decision is recorded.
+
+## 2026-04-30 — Add `applied_pending` non-terminal status to suggested fixes
+
+**Context:** The verifying banner forces a synchronous verdict — worked / didn't / partial — but a lot of real MSP fixes are async. Engineer ran the script but is waiting on the client to power-cycle, AD replication, an O365 license sync. With only the existing outcomes, the engineer either leaves the banner stale (eroding the verifying signal) or guesses wrong (corrupting outcome data). User flagged the gap directly. Today's `NudgeBanner` "Still checking" button just silences the nudge — it doesn't tell the system anything.
+
+**Decision:** Add a fourth, non-terminal outcome `applied_pending`, parallel to `applied_partial`. Required `pending_reason` Text column stores the "what are you waiting on?" reason. Outcome endpoint allows pending → {success, failed, partial, dismissed} transitions; pending stamps `applied_at` but NOT `verified_at` (it's parked, not verified). Resolution-note generator frames the fix as provisional (no closure language); escalation-package generator surfaces pending verification as the leading hypothesis with a reference to what's being waited on. Frontend exposes the state via a new `PendingBanner` component (info-tone, mirrors `PartialBanner`) plus a "Waiting to verify…" overflow option in the verifying banner. `NudgeBanner` "Still checking" now records pending with a reason instead of just silencing.
+
+**Rejected:**
+
+- **Reuse `applied_partial`.** Semantically wrong — partial means "I did some of it." Pending means "I did all of it, just can't tell if it worked." Generators write different prose for each, and conflating them would lose the distinction in the customer-facing resolution note and the next-engineer escalation handoff.
+- **Add a `pending_reason` column without a new status.** The status field is what the dashboard, banner, and generators all branch on. Hiding pending state in a separate column would proliferate `IF pending_reason IS NOT NULL` checks across every consumer.
+- **Cross-session "Follow-ups" dashboard rollup in v1.** Per-session `PendingBanner` is the chat-anchored reminder. Add the dashboard surface only if engineers report losing track across multiple pending sessions in pilot use.
+- **Optional follow-up timer ("remind me in 30m").** Out of scope; nice-to-have but not the wedge.
+
+**Consequences:**
+
+- Engineers can park a fix honestly without losing the verifying signal. The state survives across sessions because it's persisted server-side.
+- `pending_reason` is preserved as audit trail when the engineer advances pending → success/failed/dismissed; it is not auto-cleared. Intentional — it tells the next reader "we waited for X, then it worked."
+- New consumers of `FixStatus` must handle the `applied_pending` case. Currently three: the banner derivation in `AssistantChatPage`, the resolution-note generator, and the escalation-package generator. All three updated in this change.
+- Migration `c0f3a4b7e91d` is reversible — downgrade rewrites pending rows back to `applied_partial` and copies `pending_reason` into `partial_notes` if the partial slot was empty, then drops the column.

+
+## 2026-04-30 — Allow `escalated_to_id` to send chat messages in claimed sessions
+
+**Context:** During browser QA, clicking "Get AI analysis" on the magic-moment screen returned `POST /ai-sessions/{id}/chat → 400`. The senior tech who claimed the session is stored as `escalated_to_id` on `AISession`, not `user_id` (which remains the junior who created the session). `unified_chat_service.send_chat_message` queried `WHERE ai_sessions.user_id = :user_id`, so the senior's ID never matched and the endpoint rejected the request.
+
+**Decision:** Extend the ownership check in `send_chat_message` to `OR ai_sessions.escalated_to_id = :user_id` using SQLAlchemy `or_()`. This is the minimal, correct fix: the session model already has a semantically valid "also owns" field for the claiming senior; extending the WHERE clause makes that ownership real.
+
+**Rejected:**
+
+- **Transfer `user_id` to the senior on claim.** Breaks the audit trail — `user_id` is the originating engineer throughout the session lifecycle. Any query scoped to "sessions this engineer worked on" would silently lose the junior's history.
+- **A separate `can_send_message` service method.** Adds indirection with no benefit for v1. One `or_()` line in the existing query is sufficient.
+- **Checking a role/permission flag instead.** Role gating (engineer/admin) already happens at the claim endpoint. The chat-send check is about session ownership, not role. Mixing the two concerns would be confusing.
+
+**Consequences:**
+- Seniors can send AI briefings and continue chat work in sessions they have claimed. Core escalation pickup flow unblocked.
+- Any future caller of `send_chat_message` should be aware that "user_id or escalated_to_id" is the ownership rule. The service-level check is the single enforcement point.
+- `user_id` remains the originating engineer for all audit, history, and analytics queries. No data migration needed.

+
+## 2026-04-29 — Consolidate the three per-escalation AI calls into one structured generation
+
+**Context:** A single user-initiated escalation currently triggers three separate Sonnet calls, all summarizing the same source material (session state, steps taken, "what we know") from slightly different angles:
+
+1. `_build_escalation_package_enhanced` — runs in the background `enrich_escalation_async` task, builds a rich JSON payload that's saved to `ai_session.escalation_package`.
+2. `_generate_ai_assessment` — also background, returns the magic-moment screen fields (`likely_cause`, `suggested_steps[]`, `confidence`).
+3. `generate_status_update` — engineer-triggered when they click "Ticket Notes" / "Client Update" / "Email Draft" in the conclude modal, generates audience-specific PSA prose.
+
+The user surfaced the smell: the engineer is *typically* generating a status update during the escalate flow, so the AI assessment work is being done twice with overlapping context and the engineer's PSA prose is being thrown away. Live test on 2026-04-29 also showed that bumping the assessment timeout 15s → 45s did NOT fix the empty-placeholder bug — meaning the architectural smell is also a demo blocker.
+
+**Decision:** ONE structured AI call per escalation that produces a single payload covering both the magic-moment screen's diagnostic fields AND the PSA-ready prose. Persist to `SessionHandoff`. The conclude modal's "Ticket Notes" button reads from the saved prose instead of calling the model. "Client Update" and "Email Draft" buttons trigger a cheap Haiku transformation over the saved prose (tone shift only, not a re-summarization).
+
+Proposed payload shape (final form decided during implementation):
+
+```json
+{
+  "summary_prose": "<PSA-flavored ticket-notes paragraph>",
+  "what_we_know": ["<one-liner>"],
+  "likely_cause": "<one sentence>",
+  "suggested_steps": ["<short step>"],
+  "confidence": "low | medium | high",
+  "audience_variants": {"client_update": null, "email_draft": null}
+}
+```
+
+`audience_variants` filled lazily on first user request, cached.
+
+**Rejected:**
+
+- **Just bumping the timeout further.** Already tried 5s → 15s → 45s. The architectural redundancy is the real cost — even if Sonnet completed reliably, three calls per escalation is wasteful and creates three places where state can diverge.
+- **Reusing the engineer's status update content as the AI assessment.** User's first instinct, but: status updates aren't always generated (engineer has to click), they're audience-specific (so you'd pick which one to copy), and they're prose without the structured fields the magic-moment screen needs. The right consolidation is the OTHER direction — generate ONE structured payload that the status-update buttons consume.
+- **Switching the assessment to Haiku for speed.** Faster but solves only the latency symptom, not the redundancy. Doesn't help the conclude modal's status-update buttons.
+
+**Consequences:**
+
+- Magic-moment screen populates in ~5s instead of 25s+ (work happens in the foreground escalate path, not in a background task that races with the senior's pickup).
+- Token spend per escalation drops by ~60% — one Sonnet call replaces two; the third (audience variants) becomes Haiku.
+- Engineer's "Ticket Notes" button is instant — no model round-trip.
+- Schema enforcement matters. The current `_generate_ai_assessment` returns freeform prose that the frontend stuffs into `assessment_text` because the structured fields aren't reliably parseable. The new call must use Anthropic's structured output / tool-use to enforce the schema.
+- Migration concern: `ai_session.escalation_package` JSON column has live data on existing sessions. Keep it READABLE for backward compatibility; just stop *writing* the enhanced payload from `enrich_escalation_async`. If downstream queue summaries depend on it, dual-write the basic snapshot.
+- Test fixtures (`test_handoff_manager.py`, `test_session_handoffs_api.py`) currently stub `_generate_ai_assessment` via `AsyncMock`. Updating the stubs is part of the rename.
+- The frontend SSE assessment-ready subscription (added in `0f00ee5`) stays as-is — it just listens for the new event payload.
+
+---
+
+## 2026-04-28 — Tag the task-lane state with an owner chatId
+
+**Context:** A recurring bug — every time the user returned to test escalation work, creating a new session would flash the previous session's task-lane data (questions, actions, "Tasks" pill counts) before the new session's AI response landed. The first attempt to fix it (`8914391`) added initializer-time guards (`incomingPrefill || isPickup`) that skipped the sessionStorage restore on mount. That covered exactly two entry paths and missed every other case: in-place URL navigation, mid-flight pickup, HMR re-runs, and the gap between `setActiveChatId(B)` and the AI response that finally populates B's questions/actions. The persistence effect made it worse by writing `{chatId: activeChatId, questions: activeQuestions}` — at any moment where activeChatId had flipped before the questions were updated, sessionStorage was stamped with `{chatId: B, questions: [A's data]}` and a subsequent restore would happily render A's data for B.
+
+The root cause was that `activeQuestions` / `activeActions` / `showTaskLane` were three independent state slices implicitly assumed to be in sync with `activeChatId`. The synchronization was by convention, not by structure. Every code path that mutated them had to remember to call `resetSessionDerivedState` first; missing one created stale UI.
+
+**Decision:** Add a `taskLaneOwnerChatId` state that records *which chatId the in-memory questions/actions belong to*, set at every site that populates them (sendPrefill, selectChat, handleSend, handleTaskSubmit, handleResumeNew, refreshFacts, handleApplyFix), cleared in `resetSessionDerivedState`. The persistence effect writes ownerChatId as the chatId tag. Render is gated on `taskLaneOwnerChatId === activeChatId` and ANDed into all three render conditions (toolbar Tasks button, narrow-viewport floating drawer, main side panel). The mount-time `skipTaskLaneRestore` guard stays as belt-and-braces for the prefill/pickup entry-flash window, which the owner-gate alone doesn't cover.
+
+**Rejected:**
+- **More entry-path guards.** That's whack-a-mole — the next path nobody anticipated will reproduce the bug. The owner-gate makes the bug structurally impossible regardless of which path triggers it.
+- **Combining the four state slices into a single tagged object.** Cleaner long-term but a bigger refactor with more touch points. The owner-tracking approach gets the structural guarantee with a minimal diff and keeps the existing setState patterns.
+- **Inlining the comparison at every render site.** Works but proliferates the comparison; one named derived value (`taskLaneIsForActiveChat`) reads better and groups the gate with the persistence-effect / state declarations as a named concept.
+
+**Consequences:**
+- Stale task-lane data is structurally unable to display. The lane is hidden during any window where `ownerChatId !== activeChatId`, no matter what mutation path got you there.
+- Adding new sites that populate `activeQuestions` / `activeActions` requires also setting `taskLaneOwnerChatId`. The pattern is documented in the commit message and visible in every existing populate site as a paired call.
+- The mount-time `skipTaskLaneRestore` guard is now redundant in steady-state but kept for the few-hundred-ms flash window between component mount and the first sendPrefill / selectChat effect. Deleting it would re-introduce a (smaller) flash without strong reason.
+- Future task-lane state slices (e.g. `facts`, `activeFix`) follow the same pattern: gate their visibility on the owner check via the existing render conditions. Tagging more slices with their own `*OwnerChatId` is a future refactor if the slices diverge.

+PR #164 commits (oldest → newest):
 
-Previous session fixed the 54 real backend failures left after #149. The default backend suite is now green locally:
+1. `ba36c47 feat(billing): reconcile plan taxonomy and add Stripe sync script` — migration `4ce3e594cb87` renames `plan_limits.plan='team'` → `'enterprise'` (defensive update of any subscriptions on the old slug; dev had zero), adds `starter` row with caps interpolated between free and pro. Code rename across schemas, `Subscription` paid-plan checks, admin endpoints, frontend `useSubscription`. Resource visibility (`Tree.visibility='team'`, `StepLibrary.visibility='team'`) is a separate domain and intentionally untouched. New `backend/scripts/sync_stripe_plan_ids.py` — idempotent upsert of `plan_billing` rows from Stripe products by exact name match, picks active monthly recurring price, leaves annual fields NULL by design.
+2. `a628b24 chore(dev): pass STRIPE_* env to backend container` — wires `STRIPE_*` + `SELF_SERVE_ENABLED` + `INTERNAL_TESTER_EMAILS` through `docker-compose.dev.yml`. New repo-root `.env.example`.
+3. `8494366 feat(billing): add INTERNAL_TESTER_EMAILS allowlist for self-serve soft cutover` — `Settings.is_internal_tester` + `is_self_serve_active_for`, new `get_current_user_optional` dep, `/config/public` honors allowlist for authenticated callers, `/auth/register` allows allowlisted emails without invite code. 5 regression tests in `test_config_public.py`.
+4. `8649a4a docs: refresh CURRENT-STATE, ROADMAP, README, DECISIONS for self-serve cutover` — CURRENT-STATE bumped with PR #159–164 entries; ROADMAP got a "Status as of 2026-05-07" preamble (historical content preserved underneath); README fixed legacy `patherly_postgres` and `UI-DESIGN-SYSTEM.md` references; DECISIONS appended two entries.
+5. `2c9f5e9 fix(frontend): page-title — escapes + propagate plan taxonomy through frontend types` — `LandingPage.tsx` had `—` (six literal characters) inside JSX attribute strings, rendering as literal text in browser tabs. Replaced with literal em dash. PageMeta default tagline updated from "Decision Tree Platform" (stale) to "AI-Powered Troubleshooting for MSPs". Fixed TS errors that surfaced from the previous taxonomy commit not propagating through frontend types — `types/{account,admin,billing}.ts`, `admin/{AccountsPage,InviteCodesPage}.tsx`, `AccountSettingsPage.tsx`, `subscription/CheckoutButton.tsx`. tsc -b clean, lint clean.

+2. Squash-merge PR #164.
+3. **Phase O manual ops** (after merge):
+   - Stripe Dashboard live-mode: 3 Products, monthly Prices for Starter ($19.99) + Pro ($29.99), no Prices on Enterprise (sales-led), Customer Portal with plan-switching disabled, webhook at `https://api.resolutionflow.com/api/v1/webhooks/stripe` with 5 events. Save live signing secret.
+   - Railway prod env: `STRIPE_SECRET_KEY=sk_live_...`, `STRIPE_WEBHOOK_SECRET`, `STRIPE_PUBLISHABLE_KEY` + `VITE_STRIPE_PUBLISHABLE_KEY` (frontend redeploy required — Vite bake-at-build, Lesson 60), `OAUTH_REDIRECT_BASE=https://resolutionflow.com`, `SELF_SERVE_ENABLED=false` (still false at this point), `INTERNAL_TESTER_EMAILS=<allowlist>`, prod Google + Microsoft OAuth credentials.
+   - Run sync against prod backend: `railway run python -m scripts.sync_stripe_plan_ids`. Verify `plan_billing` rows have `sk_live_*` price IDs.
+4. Internal validation (Phase O Task 46): 9 scenarios with internal testers whose emails match `INTERNAL_TESTER_EMAILS`.
+5. Flag flip (Task 47): email pilots, set `SELF_SERVE_ENABLED=true` + `VITE_SELF_SERVE_ENABLED=true` (frontend redeploy). PostHog signup-funnel dashboard + Sentry alert at >1/hour Stripe webhook errors.
 
-- 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.
+## Open issues from this session (non-code, user-side)
 
-Test/harness fixes:
+- **Apex DNS missing.** `resolutionflow.com` (apex) returns no A/CNAME at the authoritative DNS (Namecheap per SOA `dns1.registrar-servers.com.`). When `www` was reconfigured in Railway, the apex record got dropped from the zone. `www` works (cert provisioned 2026-05-08 01:40 UTC, valid Let's Encrypt SAN). Symptom: apex unreachable from user's machine; Stripe verifier "URL couldn't be reached." User to re-add apex record at Namecheap (ALIAS Record host=`@` value=`c9g7uku8.up.railway.app`) or re-add the apex as a Railway custom domain and follow Railway's DNS instructions. The Railway path is more durable.
+- **Edge HSTS sticky state on user's machine.** Browser remembers the earlier broken-cert visit. Fix: `edge://net-internals/#hsts` (delete `resolutionflow.com` and `www.resolutionflow.com`) + `#dns` clear host cache + `#sockets` flush. Cert IS valid on the wire (proven by `curl --resolve` returning 200 OK from the user's box).
 
-- 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`.
+## Carry-forward
 
-## 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.
+- Annual pricing intentionally NOT implemented — user wants exit flexibility ("want to be able to exit if necessary without breaching any terms"). Schema columns (`annual_price_cents`, `stripe_annual_price_id`) preserved as nullable for future re-enable. `sync_stripe_plan_ids.py` leaves annual fields NULL.
+- `INTERNAL_TESTER_EMAILS` parsed comma-separated → normalized lowercase list. Anonymous callers always see the global flag — allowlist never leaks via unauthenticated request content (regression test enforces).
+- Office-hours design doc from this session at `~/.gstack/projects/chihlasm-resolutionflow/abc-feat-self-serve-signup-phase-2-design-20260507-112020.md`. Captures the "documentation builder" thesis (cut branching Flows from pilot UI, focus on Day 1 onboarding checklist + 3 deep-capture procedures + Hudu/IT Glue/CW output). Pre-build assignment: 3 cold calls with external Directors of Onboarding before scoping the build. NOT yet adopted as roadmap — gated on the validation calls.
+- Frontend lint shows 3 warnings in `coverage/` (auto-generated). Untouched.
+- Backend env: `SALES_LEAD_RECIPIENT_EMAIL`. Frontend env additions for cutover: `VITE_SELF_SERVE_ENABLED`, `VITE_GOOGLE_CLIENT_ID`, `VITE_MS_CLIENT_ID`, `VITE_OAUTH_REDIRECT_BASE`, `VITE_CALENDLY_URL`, `VITE_STRIPE_PUBLISHABLE_KEY`.

+## 2026-05-08 03:30 UTC — Claude — PR #164 self-serve cutover code blockers, doc refresh, page-title bug, DNS triage
+
+**Accomplished:**
+
+- Merged PR #162 (self-serve Phase 2 frontend) and PR #163 (seed users email-verified) into main via Gitea API squash merge. Created branch `feat/billing-plan-taxonomy` off the new main; pushed 5 commits closing the last code blockers for Phase O cutover. PR #164 opened at gitea pulls/164.
+- Plan taxonomy reconciliation. Discovered the marketing surface (PricingPage, Stripe products) was wired for `Starter / Pro / Enterprise` while backend was on `free / pro / team`; `BillingPlan` schema's `Literal["pro","starter","team","enterprise"]` could accept FK-violating values; `plan_billing` was unseeded. Migration `4ce3e594cb87` renames `plan_limits.plan='team'` → `'enterprise'` (defensive update of any subscriptions on the old slug; dev had zero), adds `starter` row with caps interpolated between free and pro (`max_trees=10`, `sessions=75`, `users=1`, `ai=15/mo`, no KB Accelerator, no custom branding, no priority support). Code rename across schemas (`invite_code`, `billing`, `admin`, `subscription`), `Subscription` paid-plan/`has_pro_entitlement` checks, `admin_dashboard.py`, `admin.py`, frontend `useSubscription.isPaidPlan`. Resource visibility (`Tree.visibility='team'`, `StepLibrary.visibility='team'`) is a separate domain (means "shared with my account") and intentionally untouched. 86/86 passing across subscription/billing/plan/invite/admin sweep after the rename. Conftest plan_limits seed + `_seed_plan_limits` helper made a true upsert.
+- New `backend/scripts/sync_stripe_plan_ids.py` — idempotent upsert from Stripe products by exact name match (`ResolutionFlow Starter / Pro / Enterprise`), picks active monthly recurring price, leaves annual fields NULL by design. Works against test or live keys via `STRIPE_SECRET_KEY`. Run against test mode populated `plan_billing` for all 3 tiers in dev DB. Annual pricing intentionally skipped per user's exit-flexibility constraint.
+- Stripe MCP work (test mode, `livemode=false`): archived leftover Enterprise `$500/mo` test price (had to clear the product's `default_price` first — Stripe blocks archive otherwise). Verified test-mode product set: Starter $19.99/mo, Pro $29.99/mo, Enterprise no price (sales-led).
+- `INTERNAL_TESTER_EMAILS` allowlist. Phase O Task 46 needed it as a code blocker (flagged in prior SESSION_LOG as "backend support is NOT yet built"). `Settings.is_internal_tester` (case-insensitive membership) + `is_self_serve_active_for(email)` (returns global flag OR allowlist hit) centralize the check. New `get_current_user_optional` dep — best-effort auth that returns `None` instead of 401, used by `/config/public` so the same endpoint serves anonymous and authed. `/config/public` returns `self_serve_enabled=true` for authenticated allowlist members; `/auth/register` allows allowlisted emails without invite code. 5 regression tests including "anonymous callers always see the global flag" (prevents leak via unauthenticated request content).
+- Stripe env passthrough: `docker-compose.dev.yml` now wires `STRIPE_*` + `SELF_SERVE_ENABLED` + `INTERNAL_TESTER_EMAILS` into the backend container. New repo-root `.env.example`. `backend/.env.example` updated with the self-serve cutover vars.
+- Page-title bug fix on `LandingPage.tsx`. Two JSX attribute strings (`title="..."`, `description="..."`) had `—` (six literal characters) — JSX attribute strings don't process JS escape sequences, so the browser tab and OG description rendered the literal text instead of an em dash. Replaced with the literal em dash character. Verified by grep — every other `\u...` in the codebase is inside a real JS string (`'...'` literal or `{...}` JSX expression) where escapes resolve at compile time. PageMeta default tagline updated from stale "Decision Tree Platform" to "AI-Powered Troubleshooting for MSPs" (matches index.html and brand positioning).
+- Frontend taxonomy followups (caught by tsc -b after rebuild). The earlier taxonomy commit didn't propagate through frontend types: `types/account.ts`, `types/admin.ts`, `types/billing.ts`, `admin/AccountsPage.tsx` (state type, select onChange cast, `<option value="team">` rendered UI), `admin/InviteCodesPage.tsx` (PLAN_OPTIONS array, state type, onChange cast), `AccountSettingsPage.tsx` (`plan !== 'team'` check + CheckoutButton prop), `subscription/CheckoutButton.tsx` (prop type + planLabels). All updated to `'free' | 'pro' | 'starter' | 'enterprise'`. tsc clean. Lint clean (3 warnings only in auto-generated `coverage/`).
+- Doc refresh commit (`docs: refresh CURRENT-STATE, ROADMAP, README, DECISIONS for self-serve cutover`). CURRENT-STATE bumped to 2026-05-07; added entries for PR #159–164; refreshed What's In Progress / What's Next around Phase O. ROADMAP got a "Status as of 2026-05-07" preamble (months-stale historical content kept underneath as record); In Progress and What's Next sections updated. README fixed legacy `patherly_postgres` Docker command, project-tree path, `UI-DESIGN-SYSTEM.md` reference; added `AGENTS.md`, `PROJECT_CONTEXT.md`, `PRODUCT.md` to docs table. DECISIONS appended two entries (taxonomy reconciliation, allowlist).
+- Office-hours session ran via `/office-hours` skill earlier in this session. Design doc saved at `~/.gstack/projects/chihlasm-resolutionflow/abc-feat-self-serve-signup-phase-2-design-20260507-112020.md`. Captured the "documentation builder" thesis — cut branching Flows from pilot UI, focus product around FlowPilot + Day 1 onboarding checklist as navigational frame + 3 deep-capture procedures (M365 tenant build, Windows server build, credential vault) + Hudu/IT Glue/ConnectWise output. Founder is a Director-of-Onboarding at his own MSP (Andrea Henry); pre-build assignment is 3 cold calls with external Directors of Onboarding before scoping. NOT yet adopted as roadmap.
+- DNS / cert triage: `www.resolutionflow.com` was unreachable (Railway "train hasn't arrived" page) — user added it as a custom domain in Railway, cert provisioned at 2026-05-08 01:40 UTC, `www` now serves 200 with valid Let's Encrypt SAN. Apex `resolutionflow.com` separately discovered to have NO A/CNAME at authoritative DNS (Namecheap per SOA `dns1.registrar-servers.com.`). When user reconfigured `www`, the apex record dropped from the zone. From Railway-edge IP both names work fine when DNS is forced (proven by `curl --resolve` returning 200 OK from user's box) — so the apex cert is also valid; the failure mode is purely DNS-level absence. User asked for HSTS clearance steps in Edge — provided `edge://net-internals/#hsts`, `#dns`, `#sockets` walkthrough plus Linux DNS flush options.
+
+**Left for next session:**
+
+- Verify PR #164 CI green, then squash-merge.
+- Phase O manual ops sequence (Stripe Dashboard live-mode setup, Railway prod env vars including `INTERNAL_TESTER_EMAILS`, run `sync_stripe_plan_ids.py` against prod, internal validation Task 46, flag flip Task 47, PostHog dashboards, Sentry alert).
+- User-side: re-add apex DNS record at Namecheap (ALIAS `@` → `c9g7uku8.up.railway.app`, or re-add apex in Railway), clear Edge HSTS state.

+
+## 2026-05-07 11:45 EDT — Codex — Push PR #162 CI runner setup fixes
+
+- Inspected Gitea PR #162 via public API. PR head was `380fcf7` and all CI jobs failed quickly; pushed local commits through `4a37a47`, including Python 3.12 setup for Gitea backend/e2e jobs.
+- New run on `4a37a47` showed frontend still failed quickly while backend/e2e remained pending. Root cause likely same class of runner drift: Gitea frontend/e2e jobs used `npm` without setting up Node.
+- Added explicit `actions/setup-node@v4` with Node 20 to Gitea frontend and e2e jobs. This keeps CI from relying on runner ambient Node/npm.
+- Files touched: `.gitea/workflows/ci.yml`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-05-07 11:30 EDT — Codex — Standardize backend Python on 3.12
+
+- Standardized repo declarations around Python 3.12: added `.python-version` pinned to 3.12.13, updated stale Python 3.11 docs, and added explicit Python 3.12 setup steps to Gitea CI. GitHub CI was already updated to Python 3.12 by the user.
+- Installed pyenv Python 3.12.13 and created `backend/venv` from that interpreter. Installed `backend/requirements-dev.txt` into the venv.
+- Verified native `python --version` and venv `python --version` both report 3.12.13. Verified native `pytest 8.4.2` and `alembic 1.18.3` with explicit safe test env vars; plain pytest import still depends on local `.env` values being valid.
+- Rebuilt and restarted the dev backend container with `docker compose -f docker-compose.dev.yml build backend` and `up -d backend`; confirmed `docker exec resolutionflow_backend python --version` reports 3.12.13.
+- Files touched: `.python-version`, `.gitea/workflows/ci.yml`, `.github/workflows/ci.yml`, `README.md`, `DEV-ENV.md`, `.ai/PROJECT_CONTEXT.md`, `.ai/DECISIONS.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-05-07 11:14 EDT — Codex — Recheck native Python availability
+
+- Re-ran the startup ritual and checked the host Python state after the user reported fixing the missing native Python issue.
+- Verified `python` and `python3` resolve to `/config/.pyenv/shims/*` and run Python 3.12.10. `pip` and `pip3` are available as pip 25.0.1 under the same pyenv install.
+- Confirmed there is no native `python3.11`, pyenv currently lists only `3.12.10`, no repo virtualenv exists under `backend/venv`, `backend/.venv`, or root `.venv`, and `python -m pytest --version` from `backend/` fails with `No module named pytest`.
+- Conclusion: native Python is present, but it is not yet a ready backend dev/test environment for ResolutionFlow. Docker remains the reliable path for pytest/alembic until a Python 3.11 virtualenv with `backend/requirements*.txt` is installed.
+- Files touched: `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-05-06 — Claude — Self-serve signup Phase 2 (frontend + cutover code) shipped on `feat/self-serve-signup-phase-2`
+
+- Executed Tasks 27–44 of `docs/superpowers/plans/2026-05-06-self-serve-signup-phase-2-frontend-cutover.md` via `superpowers:subagent-driven-development`. 18 commits on `feat/self-serve-signup-phase-2` (off `main` `f918b76`); HEAD `c75ce0c`. Each task: dispatched implementer subagent with full task text + curated context, then spec-compliance + code-quality review subagents; review issues either fixed in-flight via `git commit --amend` or noted as deferred scope.
+- Backend (Phase I, Tasks 27–31): `BillingService.open_customer_portal` + `GET /billing/portal-session`; `PATCH /users/me/onboarding-step` + dismiss-rest sibling; public `POST /sales-leads` (5/hr/IP); `/admin/plan-limits` GET/PUT round-trips `plan_billing` in one transaction with NOT-NULL guards on `display_name|is_public|is_archived|sort_order`; `BillingService.invalidate_billing_cache` no-op stub; `GET /config/public` (`{self_serve_enabled, oauth_providers}`); `auth/register` invite-code gate now `REQUIRE_INVITE_CODE and not SELF_SERVE_ENABLED and not invite_code`. Also (T36): `GET /accounts/invites/{code}/lookup` (public, joinedload account+inviter); OAuth callback honors `account_invite_code+invited_email`, rejects existing-email user with `email_already_registered_use_login`. Also (T42, T44): `GET /plans/public`; `POST /beta-signup` returns 307 to `${FRONTEND_URL}/register?from=beta`. `OnboardingStatus` extended with `email_verified`+`shop_setup_done`; `UserResponse` exposes `onboarding_step_completed`+`onboarding_dismissed`.
+- Frontend (Phases J–N, Tasks 32–44): `useBillingStore` Zustand store + `useBillingPoll` mounted in `AppLayout`; `useFeature` / `useFeatureLimit` (60s module cache, lazy `/usage/{field}` fetch with silent fallback — endpoint deferred) / `useTrialBanner` (fractional-day boundary so 24h = warning); `FeatureGate` / `UpgradePrompt` (inline `FEATURE_CATALOG`) / `EmailVerificationGate` (mounted in AppLayout around `<ViewTransitionOutlet />`). `RegisterPage` redesign with OAuth buttons + invite-code conditional; `OAuthCallbackPage` with CSRF state validation + UTF-8-safe base64url state encoding (factored into `lib/oauthState.ts`); `useAppConfig` hook. `AcceptInvitePage` at `/accept-invite` with locked email; `EmailVerificationBanner` refactored to design-system tokens; `EmailVerificationWall` polished; `VerifyEmailPage` at `/verify-email` with single-fire ref guard; `WelcomeRouter` + `WelcomeStep1/2/3` at `/welcome*`; `TrialPill` in topbar (8 stages); `NextStepCard` + `SetupChecklist` (replace orphaned `OnboardingChecklist`); `PricingPage` at `/pricing`; `ContactSalesPage` at `/contact-sales`; `LandingPage` got "See pricing" CTA + replaced beta-signup form with `<Link>`.
+- Final cross-cutting review caught one real bug — relative `/beta-signup` 307 target landing on API origin instead of frontend — fixed via amend (HEAD `c75ce0c`).
+- Tests: ~165+ new tests across backend pytest + frontend vitest. Sweep at end-of-branch all-green; tsc -b clean.
+- Phase O (Tasks 45–47) is explicit manual operations: Stripe live-mode setup, internal validation via `INTERNAL_TESTER_EMAILS` per-email allowlist (backend support for that allowlist is NOT yet built), feature-flag flip + week-1 monitoring. Surfaced as the resume point in HANDOFF.md.
+- Working tree was dirty before this session (`.ai/HANDOFF.md`, `.env.example`s, `core.*` core dumps, `docs/architecture/`, `docs/tutorials/`); intentionally not staged into Phase 2 commits. Files touched: see `git log --oneline f918b76..HEAD` on `feat/self-serve-signup-phase-2`.

+## 2026-05-02 ~01:00 UTC — Claude — In-product User Guides Diátaxis rewrite shipped (PR #159)
+
+- Audited the in-product `/guides` collection against live UI via `/browse` (engineer + owner test users). Existing 15 guides predated the FlowPilot pivot — every "click X in the sidebar" reference was wrong (Dashboard → Home, All Flows → Flows, Sessions → History, Exports gone, etc.). Three guides described surfaces that no longer exist: Maintenance Flows, AI Assistant page, Flow Assist Sparkles button. Findings written to `/tmp/guides-audit.md`.
+- Rebuilt `frontend/src/data/guides.ts` from scratch as 43 problem-oriented Diátaxis how-tos under 10 categories. Single-outcome each, terse imperative steps, real UI labels (Create New, Sign in, Manage, Build New Script, Send Invite, Save Settings, Create Category, etc.). Added `category: CategoryId` and optional `relatedSlugs?: string[]` to the `Guide` interface; new `Category` type and `categories` const drive the hub layout. `GuidesHubPage` now renders category sections (auto-hides empty); `GuideDetailPage` renders a Related guides footer; `GuideCard` lost its misleading "N sections" subtitle.
+- Fixed `GuideSection.tsx`: `step.tip` was rendered as plain text so `**bold**` markdown in tips rendered literally. Applied the same regex replacement used on `step.instruction`. Verified against `/guides/start-a-session` tip block.
+- Authored 14 net-new how-tos for FlowPilot-era surfaces with no prior coverage: tasklane-keyboard-flow, view-what-we-know, ask-ai-mid-session, pause-and-leave-session, resolve-a-session, record-suggested-fix-outcome, escalate-a-session, post-docs-to-ticket, send-client-update, build-script-from-scratch, open-suggested-flow, pin-a-flow, invite-teammate. Dropped change-teammate-role from scope — couldn't verify the role-change UI control without a non-owner test member.
+- Verified owner-only surfaces with `pro@resolutionflow.example.com`: Membership inline form on `/account` (not a separate `/team-members` route), `/account/categories` real button is **Create Category** (not Add), `/account/chat-retention` real fields are **Retention Period (days)** + **Max Conversations** + **Save Settings**, `/account/integrations` form fields confirmed. Three guides corrected post-audit.
+- Smoke-tested all 43 detail pages — every slug renders, no "Guide Not Found" fallthroughs.
+- Added `100.64.78.44 docker-01` entry to `/etc/hosts` (user ran `sudo tee` from a normal terminal because the LXC `!` shell prefix can't drive interactive sudo). Should now persist across `/browse` sessions on this LXC.
+- `docker exec -w /app resolutionflow_frontend npx tsc -b` clean.
+- Files touched: `frontend/src/data/guides.ts`, `frontend/src/pages/GuidesHubPage.tsx`, `frontend/src/pages/GuideDetailPage.tsx`, `frontend/src/components/guides/GuideCard.tsx`, `frontend/src/components/guides/GuideSection.tsx`, `CHANGELOG.md`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`. Working tree dirty — user not yet asked to commit.

+
+## 2026-05-01 21:55 UTC — Claude — Session-screen impeccable pass + tasklane keyboard flow shipped (PR #158)
+
+- Ran the `/impeccable` skill against the assistant chat session screen (chat history / chat bar / TaskLane). Initial design-health score: 24/40 with explicit DESIGN-SYSTEM violations (gradient surfaces in WhatWeKnow + ProposalBanner, side stripes in TaskLane done states + every banner mode, accent borderTop on lane header, backdrop blur on handoff overlay).
+- Walked through all 5 impeccable sub-passes (distill, quieter, layout, typeset, polish). Score after pass: 33/40 (+9). Biggest gains in Aesthetic & Minimalist (1→3), Consistency & Standards (1→3), Recognition Rather Than Recall (2→4).
+- Inline iterations on top of the impeccable steps: linked banner ↔ script-panel lifecycle (collapse hides both, dismiss closes both, any outcome closes both); collapsible WhatWeKnow with `sessionStorage` memory + auto-collapse-at-5-facts; full keyboard flow on TaskLane (Enter submits + auto-advances, Shift+Enter newline, Esc cancels, focus jumps to Send Responses after the last task).
+- Side fix: `ParameterizationPreview` was over-highlighting short parameter values (a `"D"` lit up every capital D in `Get-ADUser`/`Add-Type`/etc.). Added a word-boundary guard, conditional on whether the value itself starts/ends with a word character so values with leading punctuation (`"D:\\Folder"`) still match cleanly.
+- Followups logged in `.ai/TODO.md`: `ConcludeSessionModal` multi-select for paused/escalated outcomes (real feature work — engineers often need ≥2 of Ticket Notes / Client Update / Email Draft), and `bg-card-hover` Tailwind drift in `CommandPalette` (silently broken classes — two-line fix).
+- Branched as `feat/session-distill-quieter`, 4 commits (impeccable pass, parameterize fix, TODO followups, hint contrast + font-sans audit). PR #158 created via Gitea API (`$GITEA_TOKEN` env, no `gh` on this LXC). Merged into `main` as `5e10005`. Local branch deleted.
+- Validation at every commit boundary: `docker exec -w /app resolutionflow_frontend npx tsc -b`, `npm run lint`, and `npm run build` all clean.
+- Files touched: 14 frontend files (TaskLane, AssistantChatPage, ChatMessage, ProposalBanner, WhatWeKnow, WhatWeKnowItem, SuggestedFlowCard, ChatSidebar, ConcludeSessionModal, ChatTabStrip, ActionCardGroup, AddNoteButton, ParameterizationPreview), `.ai/TODO.md`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`, `CHANGELOG.md`, `CURRENT-STATE.md`.
+
+## 2026-05-01 07:20 UTC — Codex — Start issue cleanup plan sections 1 and 2
+
+- Started `docs/plans/2026-05-01-issue-cleanup-plan.md` sections 1 and 2.
+- Cleaned frontend lint to zero warnings by removing stale lint disables, tightening hook dependencies, and adding justified comments where effects are intentionally keyed to route or owner identity.
+- Added e2e selectors for session history controls and the FlowPilot command-palette entry.
+- Added `AssistantChatPage` observability for unexpected `currentChatRef` stale async discards.
+- Added `TaskLane` diagnostic help affordances for common command categories and documented #128 as "keep the existing responsive side-panel/bottom-drawer behavior until pilot feedback says otherwise."
+- Verified `npm run lint`, `npx tsc -b`, and `npm run build` in `resolutionflow_frontend`; build only reported the existing Vite large-chunk warning.
+- Files touched: frontend lint-cleanup files, `frontend/src/components/assistant/TaskLane.tsx`, `frontend/src/pages/AssistantChatPage.tsx`, `frontend/src/pages/SessionHistoryPage.tsx`, `frontend/src/components/layout/CommandPalette.tsx`, `docs/plans/2026-05-01-issue-cleanup-plan.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-05-01 06:05 UTC — Codex — Clean stale TODOs and add issue cleanup plan
+
+- Removed the resolved pytest-xdist item from `.ai/TODO.md` and reset "Up next" to no selected task.
+- Removed the resolved "Add role gate to handoff claim endpoint" backlog item from `.ai/TODO.md`.
+- Updated the frontend lint cleanup TODO from 23 warnings to the current `npm run lint` result: 24 warnings, 0 errors.
+- Tried to close Gitea #127 through the API, but this environment has no Gitea token; API returned `401 token is required`.
+- Added `docs/plans/2026-05-01-issue-cleanup-plan.md` with safe tracker actions and a recommended order for clearing remaining issues.
+- Files touched: `.ai/TODO.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`, `docs/plans/2026-05-01-issue-cleanup-plan.md`.
+
+## 2026-05-01 05:40 UTC — Codex — Audit TODO backlog and Gitea issue validity
+
+- Compared `.ai/TODO.md`, inline code TODOs, and open Gitea issues against current `main`.
+- Verified pytest-xdist is already shipped (`backend/requirements-dev.txt`, `backend/tests/conftest.py`, `.gitea/workflows/ci.yml`) so the `.ai/TODO.md` xdist item is stale. Ran frontend lint in Docker; current state is `0 errors, 24 warnings`, so the lint cleanup item remains valid but its count is stale.
+- Verified Gitea issue status: #58, #60, #128, #129, #130 remain valid; #66 is partially resolved by current `.rfflow` import/export and should be narrowed to template packs/marketplace; #127 is mostly resolved by current UI copy and prompt boundaries unless an always-visible scope badge is still wanted. Open PR #124 is stale/unmergeable against current `main`.
+- Verified inline TODOs still valid: post-session contextual feedback prompt, FlowPilot analytics domain/time-entry placeholders, prompt-cache verification note unless live telemetry has confirmed it, proposal `modify` flow editor wiring, and procedural ghost-step accept/dismiss buttons.
+- Files touched: `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-05-01 03:45 UTC — Claude Opus 4.7 — QA, merge, and ship PR #156 pending-verification
+
+- Committed two logical units of pending work on `feat/fix-pending-verification`: prior session's local review fixes as `5bee264` (Codex-attributed, 5 source files + 3 `.ai/` notes) and this session's docker-exec docs as `15042af` (Claude-attributed, `.ai/PROJECT_CONTEXT.md` + `AGENTS.md`). Cleaned up a 20MB `core.22120` Chromium dump left behind by an earlier sandbox crash.
+- Resolved a tooling gap surfaced by Codex's prior session ("npm/python/python3 are not on the host path") by documenting that this code-server LXC uses bun + docker for the toolchain. The `docker exec resolutionflow_{backend,frontend}` form is now the canonical command pattern in `.ai/PROJECT_CONTEXT.md`.
+- Got `$B`/Playwright Chromium running in the code-server LXC. After the user's restart cleared the AppArmor unprivileged-userns block, Chromium still aborted at the deeper `sandbox/linux/services/credentials.cc` layer because of the LXC namespace constraint. Workaround: launch browse with `CONTAINER=1` so it auto-adds `--no-sandbox`. Also added `100.64.78.44 docker-01` to code-server's `/etc/hosts` (via `docker exec -u 0`) so the headless browser could resolve the bake-in `VITE_API_URL`.
+- Drove `/qa` against the dev stack at `http://100.64.78.44:5173`. No naturally-occurring `applied_pending` fix existed in the DB, so seeded session `4a558056-bcbd-4b51-925b-248d70eb318d` and fix `cd4ff2fd-751a-4bcb-8cfa-3c77b4864fb2` into the test state (un-resolved session, swapped supersession on the two fixes). Saved a restore script first; verified DB matches pre-test state after teardown.
+- QA result: 5/7 scripted checks PASS with concrete DB + UI evidence. Banner renders correctly ("Awaiting verification" header, "Parked" tag, fix title + pending_reason, 4 actions). "Update reason" updates server-side. "It worked" → `applied_success` with `verified_at` stamped. "Dismiss" → `dismissed` with no terminal timestamp. Page-level Resolve auto-patches `applied_pending` → `applied_success` before the resolution flow opens. Page-level Escalate fires `EscalateInterceptDialog` with the generalized "still needs an outcome" copy. 2 entry-path checks (VerifyingBanner overflow, nudge "Still checking") deferred because they require live AI-generated chat state to drive; the mutating handlers behind those entry paths are verified via the tested transitions. Report at `.gstack/qa-reports/qa-report-pending-verification-2026-04-30.md`.
+- Pushed `feat/fix-pending-verification`. Polled Gitea actions runs 161; required `CI / frontend` and `CI / backend` plus `CI / e2e` all green. Merged via Gitea API as a merge commit (`3ba4532`).
+- Post-merge cleanup: fast-forwarded local `main`, deleted `feat/fix-pending-verification` locally and on the remote. Wrote handoff updates on `chore/post-156-handoff` matching the prior `chore/post-153-handoff` pattern.
+- Files touched (this session): `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/PROJECT_CONTEXT.md`, `.ai/SESSION_LOG.md`, `AGENTS.md`, `.gstack/qa-reports/qa-report-pending-verification-2026-04-30.md`, `.gstack/qa-reports/screenshots/01-08*.png`. Plus the two prior-session-authored commits committed by this session (5 source + 3 `.ai/` notes).
+
+## 2026-05-01 02:24 UTC — Codex — Review-fix PR #156 pending-verification flow
+
+- Reviewed PR #156 for bugs and found three actionable gaps: pending fixes could be resolved from the page-level Resolve path without updating the fix outcome, the PendingBanner lacked the dismiss action described in the PR body, and new system-prompt examples used real-looking pending reasons contrary to the prompt anti-parrot lesson.
+- Applied fixes locally on `feat/fix-pending-verification`: page-level Resolve now patches `applied_pending` to `applied_success`; page-level Escalate now intercepts `applied_pending` before handoff; PendingBanner now has Dismiss; escalation intercept copy no longer says only "Verifying state"; generator prompts no longer include real-looking pending examples.
+- Verified via running containers: prompt anti-parrot guardrail `2 passed`, suggested-fix outcome suite `21 passed`, frontend `npx tsc -b` clean, frontend `npm run build` clean except the existing Vite large-chunk warning, and `git diff --check` clean.
+- Left for next session: browser QA PR #156 using CURRENT_TASK.md checklist, then commit/push local review fixes and merge.
+- Files touched: `backend/app/services/resolution_note_generator.py`, `backend/app/services/escalation_package_generator.py`, `frontend/src/components/pilot/ProposalBanner.tsx`, `frontend/src/components/pilot/EscalateInterceptDialog.tsx`, `frontend/src/pages/AssistantChatPage.tsx`, `.ai/HANDOFF.md`, `.ai/CURRENT_TASK.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-04-30 — Claude Code — Land PR #155, ship pending-verification feature on PR #156
+
+- Committed Codex's review-pass changes (atomic conditional `UPDATE` for `claim_session`, self-claim 403, queue self-exclusion, pre-flush handoff UUID, frontend dead-code removal) as `f10649a` on `feat/escalation-metric-endpoint`.
+- Pushed `feat/escalation-metric-endpoint`, un-drafted PR #155, retitled it (stripped "WIP:"), and merged via Gitea API as a merge commit (`ac42f97`). 4/4 CI checks green at merge.
+- Picked up follow-up work surfaced by the user: the suggested-fix verifying banner forces a synchronous verdict, but real fixes are often async (waiting on client power-cycle, AD replication, license sync). Added a fourth, non-terminal outcome.
+- Designed the model: new `FixStatus="applied_pending"` parallel to `applied_partial`. Distinct semantics — partial = "did some of it"; pending = "did all of it, can't verify yet." Distinct prose in the resolution-note + escalation-package generators.
+- Implemented on a fresh branch `feat/fix-pending-verification` off main:
+  - Backend: extended `FixStatus`/`FixOutcome` literals, added `pending_reason` Text column and CHECK constraint update via Alembic migration `c0f3a4b7e91d`. `patch_outcome` accepts pending, requires notes, stamps `applied_at` only (NOT `verified_at`); pending in/out transitions allowed.
+  - Frontend: new `BannerMode='pending'` + `PendingBanner` component (info-tone, mirrors `PartialBanner`). "Waiting to verify…" added to `VerifyingBanner` overflow menu. `NudgeBanner` "Still checking" button now records `applied_pending` with a reason instead of just silencing for the session — closes the loop semantically. `AssistantChatPage` banner-mode derivation maps the new status.
+  - Tests: 4 new integration tests in `test_fix_outcome_endpoint.py` covering notes-required, reason-storage with applied_at-not-verified_at semantics, pending→success transition, and pending_reason update on re-PATCH. 21/21 pass.
+- Validation: `tsc --noEmit -p tsconfig.app.json` exit 0; `alembic upgrade heads` applied cleanly.
+- Single-commit PR #156 opened: https://gitea.resolutionflow.com/chihlasm/resolutionflow/pulls/156. Branch rebased onto post-merge main.
+- Cleanup: removed 10 stray `core.*` dumps from the worktree; deleted merged `feat/escalation-metric-endpoint` locally and on the remote.
+- Files touched: `backend/app/models/session_suggested_fix.py`, `backend/app/schemas/session_suggested_fix.py`, `backend/app/api/endpoints/session_suggested_fixes.py`, `backend/app/services/resolution_note_generator.py`, `backend/app/services/escalation_package_generator.py`, `backend/tests/test_fix_outcome_endpoint.py`, `backend/alembic/versions/71efd2102f49_add_pending_status_to_suggested_fixes.py`, `frontend/src/api/sessionSuggestedFixes.ts`, `frontend/src/components/pilot/ProposalBanner.tsx`, `frontend/src/pages/AssistantChatPage.tsx`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`, `.ai/DECISIONS.md`.

+## 2026-04-30 06:25 UTC — Codex — Apply Escalation Mode review fixes
+
+- Reviewed the recent Escalation Mode wedge work and fixed the actionable findings before PR #155 is marked ready.
+- Reworked `HandoffManager.claim_session` from read-then-write to an atomic conditional update, preserving idempotent same-user retries and returning a typed conflict for a different claimant.
+- Blocked original engineers from claiming their own handoffs and filtered their own escalated sessions out of `/ai-sessions/escalation-queue`, preventing the post-escalation dashboard from showing a junior their own handoff.
+- Fixed the compatibility payload so `session.escalation_package["handoff_id"]` is populated from a preassigned UUID before flush.
+- Removed unused legacy frontend pickup state (`claiming`, `handleStartHere`, unused `onStartHere` destructuring) that made `tsc -b` fail under `noUnusedLocals`.
+- Added regression coverage for pre-flush handoff IDs, conflict handling, self-claim rejection, successful non-owner claim, and own-escalation queue exclusion.
+- Verified `git diff --check`; focused backend tests passed (`28 passed in 42.23s`); frontend `tsc --noEmit` checks passed for app and node configs. Full Vite/build script remains blocked by root-owned generated directories under `frontend/node_modules` / `frontend/dist` in this workspace, not by TypeScript errors.
+- Files touched: `backend/app/services/handoff_manager.py`, `backend/app/api/endpoints/ai_sessions.py`, `backend/app/api/endpoints/session_handoffs.py`, `backend/tests/test_handoff_manager.py`, `backend/tests/test_session_handoffs_api.py`, `frontend/src/components/flowpilot/HandoffContextScreen.tsx`, `frontend/src/pages/AssistantChatPage.tsx`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.

+## 2026-04-30 — Claude Code — Browser QA pass complete; chat ownership bug found and fixed; PR #155 ready
+
+- Ran full browser QA pass on the escalation mode feature using gstack `/qa` skill.
+- **Critical bug found and fixed (commit `dc69c9d`):** `POST /ai-sessions/{id}/chat → 400` when senior clicked "Get AI analysis" on the magic-moment screen. Root cause: `unified_chat_service.send_chat_message` checked `AISession.user_id == user_id` only; senior is stored as `escalated_to_id`, not `user_id`. Fix: `or_(AISession.user_id == user_id, AISession.escalated_to_id == user_id)` in the WHERE clause.
+- **All 7 QA scenarios passed:**
+  - Post-escalation redirect: junior routed to `/` with "Session escalated" toast.
+  - Magic-moment screen: header, metadata, two-column AI assessment, 2-option CTA rendered correctly.
+  - "I'll take it from here": claim → dismiss overlay → composer focused.
+  - "Get AI analysis": claim → briefing sent → AI responded → task lane populated (after `dc69c9d` fix).
+  - Task lane copy button: toast + checkmark visual feedback.
+  - Chip expansion: inline detail card + "Open in Tasks panel" scroll.
+  - Post-claim toolbar re-open: dismissible mode with Close-only CTA.
+- **Known non-blockers:** "Continue where X left off" path untestable on first pickup (`hasTaskLane=false` is correct v1 behavior). 409 race condition untestable with one senior account; backend logic code-reviewed and correct.
+- Backend tests: 17/17 pass.
+- Updated `HANDOFF.md` to reflect QA complete; updated `CURRENT_TASK.md` status to engineering+QA complete; appended architectural decision to `DECISIONS.md`.
+- Branch `feat/escalation-metric-endpoint` is ready for PR #155 to be marked ready-for-review.
+- **Files touched this session:** `backend/app/services/unified_chat_service.py`, `.ai/HANDOFF.md`, `.ai/CURRENT_TASK.md`, `.ai/DECISIONS.md`, `.ai/SESSION_LOG.md`.

+## 2026-04-29 04:30 EDT — Claude Code — Live QA bash, pickup bug fixes, AI summary consolidation surfaced
+
+- User on a freshly swapped computer ran the live QA flow. Identified two bugs missed by static analysis from the previous session:
+  - **Pickup landed on a blank chat surface.** Root cause: commit `8914391` had made `activeChatId` initialize from `urlSessionId`, which broke the selectChat-gating effect in `AssistantChatPage` (`urlSessionId === activeChatId` short-circuited fresh mounts). Symptom was `selectChat` never firing post-claim; messages, conversation history, and pickup-flow correctness all silently broken.
+  - **Picked-up session missing from sidebar.** Root cause: `loadChats` runs once at mount; pre-claim the session's `escalated_to_id` is null (the junior didn't specify a target), so `listSessions` doesn't return it. Post-claim `claim_session` sets `escalated_to_id` to teamadmin, but the sidebar list never refreshes.
+- Fixes (commit `0d1b305`):
+  - Replaced the `urlSessionId === activeChatId` gate with a `loadedChatIdsRef` set so selectChat fires once per URL session per page lifecycle, regardless of whether activeChatId already matches.
+  - Added `loadChats()` call in `handleStartHere` after the claim succeeds so the sidebar reflects ownership.
+- Three additional pieces folded into `0d1b305` from the same QA bash:
+  - **Enter-to-submit on the escalate forms.** Chat-input convention: plain Enter submits, Shift+Enter inserts a newline. Added optional `onSubmit` prop to `RichTextInput` (used by `EscalateModal`) and inline `onKeyDown` on the plain textarea in `ConcludeSessionModal`. The user explicitly asked for this — they want to type the reason and hit Enter without reaching for the mouse.
+  - **Dashboard `PendingEscalations` rows expand to preview.** Click a row to reveal escalation reason + step count + confidence tier + PSA ticket number. Pick Up button click-stops to still go directly to magic moment. Single expansion at a time.
+  - **`ESCALATION_AI_ASSESSMENT_TIMEOUT_SECONDS` bumped 15 → 45.** Backend logs showed Sonnet hitting the 15s timeout in field testing. Background-task architecture (e8ba74e) means this no longer blocks the user — only bounds before publishing `has_assessment: false`. **Did NOT fix the live demo.** Assessment placeholder still permanent in user's test.
+- Surfaced an architectural smell: the escalation flow makes **three** Sonnet calls — `_build_escalation_package_enhanced`, `_generate_ai_assessment`, and `generate_status_update` (engineer-triggered) — all summarizing the same source material from slightly different angles. User correctly observed: status update is typically generated during the escalate flow anyway; reusing that content would consolidate.
+- Decided the right consolidation: ONE structured AI call per escalation that returns both the magic-moment diagnostic fields (`likely_cause`, `suggested_steps[]`, `confidence`) AND PSA-ready prose. Magic moment populates immediately. Status update buttons become tone-shift transformations (Haiku) of the saved prose, not fresh summarizations. Drops to 1 call (~60% token reduction), eliminates the AI-summary placeholder bug because the work happens in the foreground escalate path. Full implementation plan written into CURRENT_TASK.md and DECISIONS.md.
+- Session ended pre-consolidation: user is updating Claude Code CLI and starting a fresh session for clean context window. All work pushed to origin (`0d1b305`). PR #155 still draft.
+- Test users for the next session (Acme MSP shared account, password `TestPass123!`): `engineer@` (junior) and `teamadmin@` (senior).
+- Files touched: `frontend/src/pages/AssistantChatPage.tsx`, `frontend/src/components/common/RichTextInput.tsx`, `frontend/src/components/flowpilot/EscalateModal.tsx`, `frontend/src/components/assistant/ConcludeSessionModal.tsx`, `frontend/src/components/dashboard/PendingEscalations.tsx`, `backend/app/core/config.py`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`, `.ai/DECISIONS.md`.
+
+## 2026-04-28 02:00 EDT — Claude Code — Plan-locked wedge polish + structural task-lane fix
+
+- Audited `docs/plans/2026-04-27-escalation-mode-wedge-design.md` against the branch and identified four locked-design / Codex-correction items not yet shipped: live AI assessment refresh, suggested-step chips, unread 6px dot on queue cards, and race-condition toast on claim conflict.
+- Shipped all four in commit `0f00ee5`:
+  - **Live AI assessment refresh.** New `HandoffAssessmentReadyEvent` type and `onAssessmentReady` handler on `streamEscalations`. `AssistantChatPage` opens a scoped SSE subscription whenever it tracks a handoff missing its AI assessment; on a matching event it calls `handoffsApi.listHandoffs(sessionId)`, finds the handoff by id, and replaces both `magicHandoff` and `overlayHandoff` in place. Closes the loop on the async-assessment commit `e8ba74e` — without this, the senior had to manually reopen the Context overlay to see the AI assessment when the background task finished.
+  - **Suggested-step chips.** New `chipsHidden` state in `AssistantChatPage`; chip strip renders above the composer when the magic-moment dissolves and `magicHandoff?.ai_assessment_data?.suggested_steps[]` is non-empty. Click prefills input and focuses; first send via `handleSend` flips `setChipsHidden(true)`; explicit X button also hides. Per-session lifetime by design (Codex correction locked).
+  - **Unread 6px dot.** localStorage-backed seen set (`rf-escalation-seen`, capped at 200 entries) hydrated in `EscalationQueue`. Card render adds a 6px `bg-accent` dot when not in the seen set. `markSeen` called on Pick Up click AND on card body click (the "open" affordance). Hover deliberately doesn't clear (Codex correction). Pick Up button's onClick now calls `e.stopPropagation()` so it doesn't double-fire the card-open path.
+  - **Race-condition toast on claim conflict.** New `HandoffAlreadyClaimedError` exception class in `handoff_manager.py`. `claim_session` now eager-loads `claimed_by_user` via `selectinload`, rejects different-user re-claims (idempotent for same-user double-clicks), and raises with `claimed_by_id` / `claimed_by_name` / `claimed_at`. The endpoint translates to HTTP 409 with structured `detail = {error: 'already_claimed', claimed_by_id, claimed_by_name, claimed_at}`. `AssistantChatPage.handleStartHere` extracts via `axios.isAxiosError`, formats `"Already claimed by {name} {time_ago}."` using the existing `timeAgo()` helper, drops `?pickup=true`, and dismisses the magic-moment so the loser flows back to the queue. Backed by 2 new unit tests (`test_claim_session_conflict_raises_already_claimed`, `test_claim_session_idempotent_for_same_user`).
+- User then reported that the task-lane stale-flash bug was still happening despite the prior fix `8914391` — "every time we work on something that's related to this, when we go back to test we create a new session and then the task lane shows unrelated session data." The previous fix only covered mount-time entry paths (prefill + pickup); any in-place transition still flashed.
+- Shipped structural fix in commit `665530f`. Introduced `taskLaneOwnerChatId` state that explicitly tags which chatId the in-memory `activeQuestions` / `activeActions` / `showTaskLane` values belong to. Set at every populate site (sendPrefill, selectChat, handleSend, handleTaskSubmit, handleResumeNew, refreshFacts, handleApplyFix). Cleared in `resetSessionDerivedState`. Persistence effect now writes `chatId: taskLaneOwnerChatId` (was `activeChatId` — that was the original write-side bug). Render gate `taskLaneIsForActiveChat = ownerChatId === activeChatId` ANDed into all three render conditions. The lane is structurally unable to display data tagged with a different chat. See DECISIONS entry. **Not yet verified in a real browser** — user is swapping computers and asked for the handoff first.
+- The two commits `0f00ee5` and `665530f` are **local-only** at session end. The user did not explicitly authorize a push, so per the handoff rule the branch was left unpushed. First action on resume is `git push`.
+- Tests: full handoff + escalation suite (`test_handoff_manager.py`, `test_session_handoffs_api.py`, `test_escalation_bus.py`, `test_flowpilot_analytics_escalations.py`) → 34 passed in 68.89s. Frontend `tsc -b` exit 0 after each commit.

+## 2026-04-27 22:30 EDT — Claude Code — Escalation Mode: unify /escalate through HandoffManager
+
+- User pushed back on the dual-path proposal: "why would we want two different escalation methods? Should the new one just be the way we escalate regardless if we're using a PSA or not using a PSA?" Right answer. Unified everything through `HandoffManager`.
+- Backend changes (commit `029680a`):
+  - `HandoffCreateRequest` gains optional `target_user_id`; rejects self-targeting.
+  - `HandoffManager.create_handoff` for intent='escalate' now does what the legacy `flowpilot_engine.escalate_session` used to: sets `session.escalation_reason` and `escalated_to_id`, builds the legacy AI-enhanced `escalation_package` via Sonnet (`_build_escalation_package_enhanced` lazy-imported with graceful fallback), and merges handoff metadata (`intent`, `handoff_id`, `snapshot`, `engineer_notes`) into it. Eager-loads `session.steps` + `session.user` via `selectinload` to dodge async lazy-load `MissingGreenlet` errors.
+  - New `HandoffManager.finalize_escalation`: generates `SessionDocumentation`, pushes to PSA, and runs `notify()` (bell-icon AppNotification + Slack/Teams external channels) — all pre-commit so persistent state lands atomically with the handoff. Pulls engineer name via a separate User query rather than relying on `session.user` lazy access.
+  - `dispatch_escalation_notifications` keeps only the fire-and-forget IO (bus publish + per-user emails) post-commit. Found and fixed an in-flight bug: had originally put `notify()` inside dispatch (post-commit), which left `Notification` rows uncommitted — moved into `finalize_escalation` (pre-commit).
+  - `/handoff` endpoint passes `target_user_id` through and calls `finalize_escalation` pre-commit.
+  - `/escalate` is now a thin shim: owner-only session lookup → `create_handoff(intent='escalate')` → `finalize_escalation` → commit → `dispatch_escalation_notifications` → return `SessionCloseResponse`. `flowpilot_engine.escalate_session` is no longer called by any endpoint.
+  - `pickup_session` accepts both `requesting_escalation` (legacy in-flight) and `escalated` (new canonical) so existing queue items migrate seamlessly.
+  - Escalation queue list (`/escalation-queue`) and sidebar count match either status.
+- Frontend: `useFlowPilotSession` optimistic update flips status to `escalated` instead of `requesting_escalation` so the page state matches the unified backend response.
+- Verified end-to-end live against the running dev stack: a single legacy `/escalate` call from `engineer@` produced status=`escalated`, a `SessionHandoff` row (`ea9b375a…`, intent='escalate'), a `SessionDocumentation`, a PSA push attempt (`no_psa` since no ticket), AND an `AppNotification` for `teamadmin@` with title "Session escalated by Jordan Tech" and link `/pilot/{session_id}?pickup=true`. Backend test suite: `1103 passed in 259.63s` with `-n auto`. Frontend `tsc -b` clean.
+- The legacy `SessionBriefing` render branch in `FlowPilotSessionPage.tsx` is now effectively dead for any new escalation (magic-moment takes over via the handoff record), but stays in place during the transition for legacy in-flight `requesting_escalation` sessions. Slated for cleanup after pilots run a couple of weeks on the unified path. `flowpilot_engine.escalate_session` is similarly orphaned and can be deleted at the same time.
+- Files touched: `backend/app/api/endpoints/ai_sessions.py`, `backend/app/api/endpoints/session_handoffs.py`, `backend/app/api/endpoints/sidebar.py`, `backend/app/schemas/session_handoff.py`, `backend/app/services/flowpilot_engine.py`, `backend/app/services/handoff_manager.py`, `frontend/src/hooks/useFlowPilotSession.ts`.
+
+## 2026-04-27 21:50 EDT — Claude Code — Escalation Mode: bell-icon notification fix; push + draft PR
+
+- User ran a live escalation test via the EscalateModal (legacy `/escalate` path) and reported that clicking the bell-icon notification "just clears the notification instead of taking me to the session". Diagnosed: navigation IS happening, but the notification link template was `/pilot/{session_id}` without `?pickup=true`, so the senior landed on `FlowPilotSessionPage` with no pickup mode. `loadSession` then hit `GET /ai-sessions/{id}` which 404'd because the senior wasn't owner / `escalated_to_id` / picked-up handler. The user perceived the resulting error state as the action having done nothing.
+- Two-part backend fix shipped in `641853a`. (1) `_build_notification_link` for `session.escalated` now ends with `?pickup=true` so notification clicks route through the senior-pickup flow (handoff-based or legacy SessionBriefing). (2) `GET /ai-sessions/{id}` access policy: any account member can now read a session's detail when status is `requesting_escalation` or `escalated`. Tenant boundary enforced by RLS — the owner-only guard was overly restrictive for explicitly-shared in-transit states. After-pickup access (handler / `escalated_to_id`) checks still apply for active/resolved sessions.
+- Verified end-to-end live: re-login as senior engineer (non-owner, non-target) and `GET /ai-sessions/{escalated-session-id}` returns 200 with full detail. Backend regression with broader subset (`test_escalation_bus`, `test_handoff_manager`, `test_session_handoffs_api`, `test_flowpilot_analytics_escalations`, `test_sessions`, `test_session_sharing`) → 94 passed in 43.26s.
+- Pushed `feat/escalation-metric-endpoint` to Gitea. Opened **draft PR #155** against `main` via Gitea API ([gitea.resolutionflow.com/chihlasm/resolutionflow/pulls/155](https://gitea.resolutionflow.com/chihlasm/resolutionflow/pulls/155)). Title prefixed `WIP:` so Gitea marks it `draft: true`. PR body links the design + test-plan artifacts and mirrors the test plan as a checklist with visual QA + e2e demo flow as the unchecked items.
+- Open question for next session: EscalateModal still calls the legacy `/escalate` endpoint, not the new `/handoff` path. The wedge demo flow (junior escalates → magic-moment renders) is cleaner if EscalateModal goes through `/handoff`. Legacy path does PSA documentation push that the handoff path doesn't, so a parallel path (legacy escalate also creates a handoff record) is probably the right call rather than full migration.

+## 2026-04-27 21:30 EDT — Claude Code — Escalation Mode: magic-moment handoff-context screen on pickup
+
+- Continued the same session that shipped the live-arrival SSE subscription. Added the magic-moment screen on top.
+- New `frontend/src/components/flowpilot/HandoffContextScreen.tsx`: presentational 4-section view (header with problem summary + domain + step count + escalated-time + priority badge; "What's been tried" with engineer notes + step-count affordance; "AI assessment" with likely_cause / suggested_steps / confidence badge; "Start here" CTA). Confidence badge accepts both numeric (0..1) and string ("low"/"medium"/"high") shapes — backend emits the latter, the frontend type says `number`, runtime handles both. Renders an explicit "assessment unavailable — model didn't respond in time" branch when `ai_assessment_data` is null (the 5s timeout from `9bdd995` fired). `prefers-reduced-motion` swaps `animate-slide-up` for `animate-fade-in`. ARIA `role=dialog` + `aria-modal=true` + focus on primary CTA on mount + Esc dismiss when used as a re-openable overlay.
+- Integration in `frontend/src/pages/FlowPilotSessionPage.tsx`: on `/pilot/:id?pickup=true`, fetch the handoff list via `handoffsApi.listHandoffs` (account-scoped via RLS, no claim required) and find the latest unclaimed escalate handoff. If found, render the screen and skip `loadSession` (the senior would 404 pre-claim because they aren't yet `escalated_to_id`). "Start here" calls `handoffsApi.claimHandoff`, drops the `?pickup=true` query, and dismisses the screen — the existing `loadSession` effect then fires because the senior is now `escalated_to_id`. New "Context" toolbar button on active sessions (visible only when the senior arrived via the magic-moment flow this session — handoff lookup on demand) re-opens the screen as a dismissible overlay.
+- Verified end-to-end against the running dev stack: `listHandoffs` returns the unclaimed handoff with full payload (engineer_notes, snapshot keys); `claimHandoff` flips session status from `escalated` → `active` and sets `escalated_to_id`; subsequent `GET /ai-sessions/{id}` succeeds. `tsc -b` exit 0. No backend changes; backend tests still `32 passed in 18.91s`.
+- Deferred to TODOs in `CURRENT_TASK.md`: suggested-step chips below the chat input (Codex correction; threads through to `FlowPilotMessageBar`); `HandoffManager._generate_snapshot` expansion to include the recent diagnostic timeline pre-claim (today's snapshot is just `problem_summary, problem_domain, status, step_count, confidence_tier`); toolbar "Context" button visibility on revisited active sessions; owner-facing `/analytics/escalations` page; Playwright e2e for the GTM Loom demo path.
+- Branch state: 3 new commits (`b8627f4` SSE subscription, `f65b657` handoff doc bump, `8e9d22e` magic-moment screen). Branch is unpushed — next session pushes + opens draft PR.
+- Files touched this slice: `frontend/src/components/flowpilot/HandoffContextScreen.tsx` (new), `frontend/src/components/flowpilot/index.ts`, `frontend/src/pages/FlowPilotSessionPage.tsx`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-04-27 21:00 EDT — Claude Code — Escalation Mode: frontend SSE subscription in EscalationQueue
+
+- Picked up `feat/escalation-metric-endpoint` after the Codex test-stabilization pass. Confirmed green starting state: focused backend subset `32 passed in 18.78s` with `-n auto`.
+- Implemented the live-arrival frontend slice. Added `streamEscalations(handlers, signal)` to `frontend/src/api/aiSessions.ts` — fetch-based `ReadableStream` reader (native `EventSource` can't send auth headers) that parses SSE frames (event/data/comment lines), buffers partial frames across chunks, ignores `: keepalive` heartbeats, dispatches `ready` and `handoff_created` events. Added `HandoffCreatedEvent` and `EscalationStreamHandlers` types in `frontend/src/types/ai-session.ts` mirroring the backend bus payload.
+- Rewrote `frontend/src/components/flowpilot/EscalationQueue.tsx`. SSE subscription with `AbortController` + exponential-backoff reconnect (1s → 30s cap, attempt counter resets on `ready`). On `handoff_created` the component refetches the queue, diffs against the previous IDs via a `sessionsRef`, prepends new arrivals (newest-first) above established cards (oldest-first preserved). New IDs are tagged for 800ms so the locked 200ms slide-in animation plays before cleanup. Tab-title flash: captures `document.title` at mount, prefixes `(N)` while `document.hidden`, clears on `focus` / `visibilitychange`, restores on unmount. `prefers-reduced-motion: reduce` swaps `animate-slide-in-bottom` for `animate-fade-in`. ARIA: `role="region"` + `aria-live="polite"` on the list, `aria-label="N escalations awaiting pickup"` on the heading; Pick Up button bumped to `py-2.5` to clear the 44px touch floor.
+- Verified end-to-end against the running dev stack. `tsc -b` exit 0. Vite HMR'd the new component without errors. Raw SSE handshake against `/api/v1/ai-sessions/escalations/stream` returned 200 with `text/event-stream; charset=utf-8` plus the locked headers (`cache-control: no-cache`, `x-accel-buffering: no`). Subscriber received the `ready` frame on connect; after posting a handoff via the API, the subscriber received the `handoff_created` frame with the full payload — wire format matches the parser exactly. Backend regression: same focused subset still `32 passed in 18.91s`.
+- Not yet verified (would need a real browser session): the slide-in animation visually plays, the tab title actually updates, the reduced-motion media-query path, AbortController cancellation on unmount, backoff after a real network blip. Wire contract is confirmed; these are visual/timing-dependent and follow from correct parser + state machine.
+- Smoke-test artifact: a single test handoff (`0f6149db…` on session `50ea20d4…`) is sitting in the engineer's queue from the verification step. Harmless; useful as visual demo data.
+- Left for next session: the magic-moment handoff-context screen — 4 sections (problem summary / what's been tried / AI assessment / Start here CTA), loads on Pick Up, dissolves into the regular FlowPilot session view. Must render gracefully when `ai_assessment` is `None` (per the 5s assessment timeout from Codex's earlier fix).
+- Files touched: `frontend/src/api/aiSessions.ts`, `frontend/src/types/ai-session.ts`, `frontend/src/components/flowpilot/EscalationQueue.tsx`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`.
+
+## 2026-04-27 EDT — Claude Code — Escalation Mode wedge: design through SSE backend (8 commits)
+
+- One long session that produced the entire planning artifact stack and most of the backend for the Escalation Mode wedge. Output of `/office-hours` (8 founder-signal session, top-tier YC archetype indicators), `/plan-eng-review` (scope reduced from "2-3 weeks greenfield" to "~6-9 days integration + metric + polish" once the existing handoff_manager surface was inventoried), `/plan-design-review` (6/10 → 9/10 with magic-moment screen, hero metric placement, and real-time arrival visual locked), and `/codex review` (12 findings, 6 applied — two-metric framing, notification routing, claim auth gate moved in-scope, unread-state fix, "Start here" CTA reframe, per-channel delivery model; 5 rejected including the full-scope reduction Codex pushed for).
+- Branched `feat/escalation-metric-endpoint` off `main` @ `c0ed6d9`. Stack at session end: `d51e95c` plan + test-plan artifacts; `52f6d03` `GET /analytics/flowpilot/escalations` endpoint with 9 tests including multi-tenant isolation; `7a5b853` claim-endpoint role gate; `07d0db9` email dispatch on escalate with graceful-degradation regression; `9f0bfd4` `EscalationMetricCard` mounted above the queue list; `a283d0d` mid-flight `.ai/` refresh; `87bd0b7` WIP commit for SSE pub/sub bus + endpoint + 7 bus unit tests + 1 dispatcher integration test + 2 endpoint tests; `ba46fc5` paused-for-Codex-review handoff. Codex picked up from `ba46fc5` and added `bc15952` / `fff8338` / `9bdd995` (test stabilization + assessment latency bound).
+- Pause was forced by a runaway local test loop: multiple stale `pytest` processes were left inside `resolutionflow_backend` after several aborted runs and contended on the same Postgres test schema. Codex diagnosed and fixed (see entry above).
+- Frontend: thin slice — added `getEscalationMetrics` to `flowpilotAnalyticsApi`, the `EscalationMetricCard` component (loading / error / zero-data states + avg + median + conversion-rate + the inline two-metric disclaimer), and mounted it above `EscalationQueue`. `tsc -b` clean.
+- Plan-stage UI decisions locked into the design doc and the codebase: dedicated 4-section magic-moment screen on Pick Up that dissolves into FlowPilot; queue stat-card + dedicated owner analytics page for the hero metric (in two places, not one); 200ms slide-in + tab-title flash on real-time arrival, no sound, respects `prefers-reduced-motion`; unread dot clears on open/claim/dismiss, NOT on hover (Codex correction). Claim role gate moved in-scope per Codex (not deferred to TODO).
+- Two TODOs added: peer-tech escalation (deferred to v2 once a pilot asks); mobile/responsive design (also v2; pre-PMF wedge demo targets desktop). Claim role gate's TODO entry was struck through in the same session because it shipped in `7a5b853`.
+- Plan and test-plan artifacts copied into `docs/plans/` under the `YYYY-MM-DD-name-design.md` / `-test-plan.md` convention so they live alongside the existing project plans, not just in `~/.gstack/projects/`.
+- Left for next session: frontend SSE subscription in `EscalationQueue.tsx` (fetch-based ReadableStream — native EventSource can't send auth headers; match `streamDocumentation` in `frontend/src/api/aiSessions.ts`), then the magic-moment handoff-context screen, then push + draft PR. Default Claude Code model is being switched from Opus 4.7 1M-context to Opus 4.7 (200k) for the next session — the resume docs are sized to be self-sufficient under the smaller window.
+- Files touched (committed): `docs/plans/2026-04-27-escalation-mode-wedge-design.md`, `docs/plans/2026-04-27-escalation-mode-wedge-test-plan.md`, `backend/app/api/endpoints/flowpilot_analytics.py`, `backend/app/schemas/flowpilot_analytics.py`, `backend/app/api/endpoints/session_handoffs.py`, `backend/app/services/handoff_manager.py`, `backend/app/core/escalation_bus.py` (new), `backend/tests/test_flowpilot_analytics_escalations.py` (new), `backend/tests/test_escalation_bus.py` (new), `backend/tests/test_handoff_manager.py`, `backend/tests/test_session_handoffs_api.py`, `frontend/src/types/flowpilot-analytics.ts`, `frontend/src/api/flowpilotAnalytics.ts`, `frontend/src/components/flowpilot/EscalationMetricCard.tsx` (new), `frontend/src/components/flowpilot/index.ts`, `frontend/src/pages/EscalationQueuePage.tsx`, `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/TODO.md`.
+
+## 2026-04-27 19:50 EDT — Codex — Stabilize Escalation Mode SSE backend tests
+
+- Diagnosed slow backend tests on `feat/escalation-metric-endpoint`. Multiple stale pytest processes were still alive inside `resolutionflow_backend` and held `resolutionflow_test` transactions open, blocking later per-test schema resets on `DROP SCHEMA public CASCADE`.
+- Reproduced a deterministic hang in `test_escalations_stream_returns_sse_content_type`: HTTPX `ASGITransport` buffers the full response body before returning, so an infinite SSE response never yielded the initial chunk and kept the auth DB dependency transaction open.
+- Fixed `stream_escalations` to release auth dependencies before the long-lived stream body with `Depends(..., scope="function")`.
+- Reworked the SSE handshake test to call `stream_escalations()` directly and consume one generator yield, then close it; kept viewer role-gate coverage through the API client.
+- Stubbed `_generate_ai_assessment()` in handoff manager/API tests so escalation handoff tests no longer wait on the real AI path.
+- Normalized account IDs inside `EscalationBus` so string UUIDs and `UUID` objects hit the same subscriber bucket; added a regression test.
+- Verified focused backend subset: serial `31 passed in 46.95s`; xdist `31 passed in 17.80s`. Confirmed no lingering pytest processes or test DB sessions afterward.
+- Follow-up in the same session: fixed the product latency risk by adding `ESCALATION_AI_ASSESSMENT_TIMEOUT_SECONDS` (default 5s) around escalation AI assessment generation. If the optional assessment times out, handoff creation continues with no assessment. Added regression coverage; focused xdist subset now `32 passed in 17.77s`.
+- Left for next session: continue frontend SSE subscription in `EscalationQueue.tsx`, then the magic-moment handoff-context screen.
+- Files touched: `backend/app/api/endpoints/session_handoffs.py`, `backend/app/core/config.py`, `backend/app/core/escalation_bus.py`, `backend/app/services/handoff_manager.py`, `backend/tests/test_escalation_bus.py`, `backend/tests/test_handoff_manager.py`, `backend/tests/test_session_handoffs_api.py`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md`, `.ai/TODO.md`.
+
+## 2026-04-26 03:50 EDT — Claude Code — Ship AssistantChatPage prefill `currentChatRef` fix; close out PR #150
+
+- User reported a troubleshooting-session bug: after answering a subset of task-lane questions and clicking *Send N of M Responses*, no AI response appeared. Traced to `AssistantChatPage`: the dashboard prefill effect set `activeChatId` after creating a new chat session but never updated `currentChatRef.current`. The `currentChatRef.current !== sentForChatId` guard in `handleSend` and `handleTaskSubmit` then bailed silently on every later request and discarded the AI's reply. The user message was already pushed to the chat before the await, so the user saw their answers but nothing else.
+- Fix: one-line addition mirroring `handleNewChat` and `handleResumeNew` — assign `currentChatRef.current = session.session_id` immediately after `setActiveChatId(session.session_id)` in the prefill effect. Branched off `origin/main` as `fix/tasklane-prefill-ref`; PR #153 opened on Gitea.
+- Authored a Playwright regression test `frontend/e2e/assistant-chat-prefill.spec.ts` that drives the real dashboard prefill flow against the real backend, stubs `/ai-sessions/*/chat` with `page.route` for deterministic turn-1/turn-2 responses, and asserts the second AI message renders. Confirmed the test fails on unfixed code at the exact assertion (`Got it — based on your answer…` never appears) and passes once the fix is restored.
+- Verified locally inside `mcr.microsoft.com/playwright:v1.58.2-noble` against the running dev stack: new spec passes, adjacent `flowpilot-chat` spec still passes, `tsc -b` clean. `resume.spec` and `history.spec` failures observed are pre-existing real-backend fixture collisions, unrelated to this change.
+- First CI run on PR #153 failed on infrastructure issues already addressed by PR #150: backend hit `Bind for 0.0.0.0:5432 failed: port is already allocated`, frontend hit `actions/upload-artifact@v4 not supported on GHES`. PR #150 was already merged (commit `87bb20b` on `main`). Rebased `fix/tasklane-prefill-ref` onto new `main` (force-push `1a8cb06` → `1559feb`), resolved a `.ai/TODO.md` conflict by keeping both backlog item sets, kicked off CI on the rebased SHA.
+- Confirmed `CI / backend (pull_request)` is now in branch protection's required-status-checks list (added during PR #150 close-out). `CI / e2e (pull_request)` left as not-required pending one more clean PR run as the threshold.
+- Recorded the broader silent-return concern in TODO backlog: the `currentChatRef.current !== sentForChatId` guard is applied across `handleSend`, `handleTaskSubmit`, `selectChat`, `refreshFacts`, `refreshActiveFix`, and `refreshPreview`. PR #153 fixes one symptom but the same pattern can mask other drift. Either log a Sentry breadcrumb on the mismatch path or distinguish "expected stale" (chat switch) from "unexpected stale" (ref never updated) so the latter alerts.
+- First CI run on the rebased SHA passed backend and frontend but failed e2e: the new prefill regression test couldn't render the task-lane question text. Diagnosed via the job log: `POST /api/v1/ai-sessions` calls `_require_ai_enabled()` and returns 503 when no provider key is set. The e2e CI job had neither `ANTHROPIC_API_KEY` nor `GOOGLE_AI_API_KEY` in env. Locally the dev backend has a real key, hence the local pass. The Playwright `page.route` stub on `/chat` was correct but never had a chance to fire because the upstream session-creation call was 503-ing.
+- Fix: added a stub `ANTHROPIC_API_KEY: ci-stub-key-not-used-by-tests` to the e2e job env in `.gitea/workflows/ci.yml`. The Playwright stub still intercepts the actual `/chat` call in the browser, so the backend never contacts Anthropic — the gate just needs to clear. Documented the convention in a workflow comment so future AI-touching e2e tests know what to expect. Pushed `11fe32f`; CI went all-green.
+- Merged PR #153 as `68fcdc6` on `main`. Local feature branch and remote both deleted via Gitea's `delete_branch_after_merge`.
+- Opened a small follow-up `chore/post-153-handoff` PR to refresh the now-stale `.ai/` files (this entry, plus `CURRENT_TASK.md` rolling forward to "no active task — pick from `TODO.md`" and `HANDOFF.md` updating to the post-merge home position). The `data-testid` audit at the top of `TODO.md` "Up next" or the `currentChatRef` silent-return audit added in this session's backlog are the natural next pickups.
+- Files touched: `frontend/src/pages/AssistantChatPage.tsx` (the one-line fix + comment), `frontend/e2e/assistant-chat-prefill.spec.ts` (new regression test), `.gitea/workflows/ci.yml` (stub `ANTHROPIC_API_KEY` for e2e), `.ai/TODO.md` (silent-return follow-up entry, plus conflict resolution preserving PR #150's backlog additions), `.ai/CURRENT_TASK.md`, `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md` (this entry).
+
+## 2026-04-25 16:41 EDT — Codex — Stabilize PR #150 e2e selectors
+
+- Investigated the remaining PR #150 failure after backend and frontend CI were green. The e2e resume smoke test was not failing because of product behavior; it used `.bg-card` plus text filtering and matched the tree filter `<select>` before the intended session card.
+- Added stable test IDs to flow session, tree, and share cards, then updated affected e2e tests to target those cards instead of Tailwind class names.
+- Hardened the CI workflow by making Postgres healthchecks authenticate as `postgres` and baking `VITE_API_URL="${PLAYWRIGHT_API_ORIGIN}"` into the e2e frontend build.
+- Verified with `git diff --check`, frontend build in Docker, no remaining `.bg-card` e2e selectors, and focused Playwright runs in an Actions-like Ubuntu container: resume spec passed, then history/library/library-start/resume/shares passed (`6 passed`).
+- Left for next session: push this WIP commit to PR #150, watch CI, merge when all three jobs are green, then enable backend branch protection and consider the e2e gate after a reliable green run.
+- Files touched: `.gitea/workflows/ci.yml`, `frontend/e2e/history.spec.ts`, `frontend/e2e/library-start.spec.ts`, `frontend/e2e/library.spec.ts`, `frontend/e2e/resume.spec.ts`, `frontend/e2e/shares.spec.ts`, `frontend/src/components/library/TreeGridView.tsx`, `frontend/src/components/library/TreeListView.tsx`, `frontend/src/pages/MySharesPage.tsx`, `frontend/src/pages/SessionHistoryPage.tsx`, `.ai/HANDOFF.md`, `.ai/CURRENT_TASK.md`, `.ai/SESSION_LOG.md`.

+## 2026-04-25 12:00 America/New_York — Claude Code — Mock final AI-provider test, cache CI deps, parallelize backend with pytest-xdist
+
+- Diagnosed why CI was still red despite Codex's local 1076 passed: a single test (`test_record_decision_persists_and_bumps_state_version`) needed `ANTHROPIC_API_KEY` because the `decision: draft_template` path calls `TemplateExtractionService` → AI provider. Patched `_extract_template_parameters` with an `AsyncMock` so the test no longer depends on AI availability. Verified.
+- Pushed Codex's WIP commit `49f8856` to PR #150 (had been local-only per handoff protocol).
+- PR #150 (`fix/ci-workflow-config`) extended with cheap CI wins: `actions/cache@v3` for pip + npm in all three jobs; dropped `--cov-report=term-missing` (the custom display step parses JSON); added `--maxfail=10` so structural breakage exits fast.
+- PR #151 (`fix/ci-pytest-xdist`) opened, stacked on #150: pytest-xdist with per-worker DB isolation. `conftest.py` reads `PYTEST_XDIST_WORKER`, computes a per-worker DB URL like `…_gw0`, and synchronously CREATEs the DB on first import. The per-test `DROP SCHEMA public CASCADE` then operates on the worker's isolated DB. Verified locally: backend suite went from 22m 27s serial → 4m 28s parallel (8 workers), 1076 passed in both cases. ~5× speedup.
+- Decided NOT to do per-test transactional rollback (bigger refactor); captured for future TODO consideration.
+- Left for next session: watch CI on both PRs, merge in order (#150 first, #151 second), then enable `CI / backend (pull_request)` as a required status check on main.
+- Files touched: `backend/tests/test_session_suggested_fixes_api.py`, `backend/tests/conftest.py`, `backend/requirements-dev.txt`, `.gitea/workflows/ci.yml`, `.ai/HANDOFF.md`, `.ai/CURRENT_TASK.md`, `.ai/TODO.md`.

 ## 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.
@@ -44,3 +362,13 @@
 - 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`.

+## 2026-05-07 UTC — Codex — Resolve PR #162 CI failures
+
+- Investigated Gitea PR #162 failing checks for `feat/self-serve-signup-phase-2`. Public status metadata was available, but job logs required Gitea login and no token was present.
+- Standardized backend development/CI Python on 3.12.13 to match the Docker image: added `.python-version`, updated Gitea CI Python setup, rebuilt the local backend virtualenv, and verified native `pytest` / `alembic` command availability with explicit local env.
+- Added explicit Node 20 setup to Gitea frontend and e2e jobs so CI no longer depends on the runner's ambient Node installation.
+- Reproduced the remaining frontend failure locally. Lint failed on Phase 2 React code because the current eslint stack flags exported pure helpers, render-time `Date.now()`, and effect-driven state synchronization.
+- Patched the affected frontend surfaces narrowly: dashboard helper exports, app-config cache handling, feature-limit cache/fetch state, trial-banner time capture, invite/OAuth route error state, pricing loading state, and OAuth authorize URL helper export.
+- Verified sequential frontend CI locally in Docker: `npm run lint` passed, `npm run test:coverage` passed (`198` tests), and `npm run build` passed with only Vite chunk-size warnings.
+- Files touched: `.python-version`, `.gitea/workflows/ci.yml`, `.github/workflows/ci.yml`, `.ai/*`, `README.md`, `DEV-ENV.md`, and the frontend lint-fix files under `frontend/src/components/dashboard`, `frontend/src/hooks`, and `frontend/src/pages`.

 ## Up next
 
-- [ ] **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.
+None selected. Pick from the backlog below or `03-DEVELOPMENT-ROADMAP.md`.
 
 ## 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.
+- [ ] **Frontend lint warnings cleanup.** `npm run lint` currently reports 24 warnings (0 errors): mostly `react-hooks/exhaustive-deps` plus a few unused eslint-disable directives. Either fix them or audit known-safe ones and add/remove eslint-disable comments intentionally. 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.
+- [ ] **Add `data-testid` attributes to e2e-critical interactive elements.** PR #152 fixed five Playwright tests by chasing UI-text changes (`Sessions` → `Session History`, `Account Settings` → `Account Management`, `/assistant` → `/pilot`, "Flow Sessions" tab, Resume button on session cards). Each was a one-line selector update, but every UI churn re-breaks them. Adding stable `data-testid` attributes on the targeted elements (page heading wrappers, tab nav, primary action buttons) and switching tests to `getByTestId` would make these immune to copy/route renames. Scope it small — start with `SessionHistoryPage` heading, the AI/Flow Sessions tab buttons, the per-session `Resume` button, and the command-palette FlowPilot option.
+- [ ] **Per-test transactional rollback in `test_db` fixture.** Bigger engineering than xdist (which we already shipped). Instead of `DROP SCHEMA public CASCADE` per test, wrap each test in a savepoint and rollback at teardown. ~30-40% additional speedup on top of xdist for test-DB-heavy tests. Real refactor; only worth it if the suite gets significantly larger or runs more frequently.
+- [ ] **Consider `pytest-testmon` for PR-time test selection.** Tracks which tests touched which source files and only re-runs affected ones. Best for small PRs touching ~few files. Adds cache-invalidation complexity; only worth it if the suite stays painfully long even after xdist.
+- [ ] **AssistantChatPage `currentChatRef` guard is a silent return** — `handleSend`, `handleTaskSubmit`, `selectChat`, `refreshFacts`, `refreshActiveFix`, and `refreshPreview` all bail with `if (currentChatRef.current !== sentForChatId) return` when stale. This is by design for chat switching, but it also silently masked the prefill-ref bug fixed in PR #153 — the user just saw "no AI response" with no log, no toast, no Sentry event. Either (a) log a `console.warn`/Sentry breadcrumb on the mismatch path so future drift is visible, or (b) split "expected stale" (chat switch) from "unexpected stale" (ref never updated) so only the latter alerts. Pair with an audit of every `currentChatRef.current = ...` assignment vs every `setActiveChatId(...)` call to make sure they're paired everywhere.
+
+- [ ] **Allow peer-tech to escalate a colleague's session.** Today `POST /ai-sessions/{session_id}/handoff` in [endpoints/session_handoffs.py:48](backend/app/api/endpoints/session_handoffs.py#L48) filters by `AISession.user_id == current_user.id`, so only the session owner can escalate. Real MSP shops have peer hand-offs: Junior A is on lunch, Junior B sees the session is stuck and should be able to escalate it. Auth tweak: switch from session-owner check to `require_engineer_or_admin` + same-account scope. Add a `handed_off_by` audit column (already exists on `SessionHandoff`) so the original-owner-vs-actual-escalator distinction is preserved. Surfaced from /plan-eng-review on the Escalation-Mode wedge plan; v1 wedge demo doesn't need this (solo-founder pilot), but capture for v2 once 3+ pilots are live and a peer-claim need surfaces.
+
+- [ ] **Mobile/responsive design for EscalationQueue + handoff-context screen.** Pre-PMF wedge demo targets desktop only — MSP techs work on laptops/desktops in shop environments. Once 3+ paying customers exist and a tech requests mobile (likely on-call use case), spec the responsive behavior: stacked card layout below `sm:` breakpoint, full-bleed handoff-context overlay on mobile, swipe-to-claim gesture instead of Pick Up button. Surfaced from /plan-design-review on the Escalation-Mode wedge plan.
+
+- [ ] **`bg-card-hover` Tailwind class doesn't resolve.** [`frontend/src/components/layout/CommandPalette.tsx:450-451`](../frontend/src/components/layout/CommandPalette.tsx) uses `bg-card-hover` as a Tailwind utility, but Tailwind v4 generates `bg-{token}` from `--color-{token}` — and the token in [`frontend/src/index.css:15`](../frontend/src/index.css) is `--color-bg-card-hover`, which generates `bg-bg-card-hover`, not `bg-card-hover`. So those classes silently produce nothing. Other call sites (KnowledgeBaseCards, TeamSummary, ProposalBanner) use the explicit `hover:bg-[var(--color-bg-card-hover)]` form which works. Fix: change the CommandPalette classes to the explicit-var form, OR add a `--color-card-hover` semantic mapping in index.css alongside `--color-card`. Surfaced 2026-05-01 during impeccable polish sweep.
+
+- [ ] **`ConcludeSessionModal` paused/escalated step forces single-artifact choice — should allow multi-select.** [`frontend/src/components/assistant/ConcludeSessionModal.tsx`](../frontend/src/components/assistant/ConcludeSessionModal.tsx) ~lines 430-474 ("Paused/Escalated: status update options"). Today the engineer clicks ONE of Ticket Notes / Client Update / Email Draft, the buttons disappear, and the result replaces them. Real MSP escalations almost always need at least two: technical notes for the next engineer's PSA AND a non-technical client update. Same for pause (client update + ticket notes for context when resuming). Recommended shape: multi-select with smart defaults — three checkboxes (`☑ Ticket Notes  ☑ Client Update  ☐ Email Draft`); for `escalated` pre-check Ticket Notes + Client Update; for `paused` pre-check Client Update only. One "Generate" button fires all selected in parallel via existing `aiSessionsApi.generateStatusUpdate(...)` (already supports the three `audience` values: `ticket_notes`, `client_update`, `email_draft`). Each result renders in its own card with its own Copy / Post-to-PSA / Send-Email action. Surfaced 2026-05-01. Feature work, not polish — touches streaming wiring for parallel calls.

 # Development Roadmap
 
-> **Last Updated:** March 18, 2026
-> **Product:** ResolutionFlow (repo: patherly)
+> **Last Updated:** May 7, 2026
+> **Product:** ResolutionFlow (repo path: `resolutionflow/`; `patherly` is the legacy internal name)
 > **Target Market:** MSP companies — IT service providers managing infrastructure and support for multiple clients

+## Status as of 2026-05-07
+
+The historical phase content below (Phase 1 through Phase 5) is preserved as a factual record. **This section is the live status overlay — read it first.**
+
+**Where we are:** Pre-PMF, Go-to-Market Validation. Backend feature-complete (50+ endpoints, 100+ tests). FlowPilot session UX is the daily-driver surface and recently went through PR #155 (escalation wedge), #156 (`applied_pending` non-terminal status), #158 (impeccable pass + tasklane keyboard flow), #159 (Diátaxis User Guides), #160 (sidebar IA + account redesign).
+
+**Currently in flight:** Self-serve signup cutover. Phase 1 backend (#161) and Phase 2 frontend (#162) merged. PR #164 (open) closes the last code blockers — plan taxonomy reconciliation (`team` → `enterprise`, add `starter`) and `INTERNAL_TESTER_EMAILS` allowlist for the soft cutover. After merge, remaining work is **manual operations only**: Stripe Dashboard live-mode setup, Railway prod env vars, internal validation pass, public flag flip. See `docs/superpowers/plans/2026-05-06-self-serve-signup-phase-2-frontend-cutover.md` Phase O for the checklist.
+
+**Product thesis being tested:** "We're not a documentation app. We are the documentation builders." Captured in `~/.gstack/projects/chihlasm-resolutionflow/abc-feat-self-serve-signup-phase-2-design-20260507-112020.md` (office-hours design doc). Pre-build assignment: 3 calls with external Directors of Onboarding (cold, no friendly contacts) to validate the framing before adopting it as the public positioning.
+
+**What's not yet decided:** Whether to formally cut branching Flows from the pilot UI surface in favor of a Project (linear procedure) + FlowPilot + Documentation-Builder positioning. Discussed in /office-hours but no implementation work scheduled — gated on the 3 external validation calls.

 ## [Unreleased]
 
+### Changed
+- **In-product User Guides rewrite** — replaced 15 feature-dump guides with 43 problem-oriented Diátaxis how-tos grouped under 10 categories (Getting started, Working a pilot session, Closing out a session, Documentation & sharing, Authoring flows, Reusable assets, AI assistance, PSA integrations, Account & team admin, Analytics). Dropped three deprecated guides (Maintenance Flows, AI Assistant page, Flow Assist sparkle button — UI no longer exists). Renamed Step Library → Solutions Library to match canonical product terminology. Corrected sidebar entry-path references throughout (Dashboard → Home, All Flows → Flows, Sessions → History, Analytics → Data, etc.). Added `category` and optional `relatedSlugs` to the Guide schema; `GuidesHubPage` now renders category sections; `GuideDetailPage` shows a "Related guides" footer when set. Authored 14 net-new how-tos covering FlowPilot-era surfaces with no prior coverage: tasklane keyboard flow, what-we-know panel, ask-the-AI mid-session, pause-and-leave, resolve a session, record a suggested-fix outcome, escalate (Escalation Mode), post docs to a ConnectWise ticket, share a client update mid-session, build a script with Script Builder, open an AI-suggested flow, pin a flow, and invite a teammate. Fixed a long-standing rendering bug where `**bold**` markdown in `step.tip` rendered literally instead of bolded — the same regex replacement now runs on tips as on instructions. Killed the misleading "N sections" subtitle on guide cards (single-section how-tos make the count noise).
+
 ### Added
+- **TaskLane keyboard-first answer flow** (#158) — Enter submits and auto-advances to the next pending task; Shift+Enter inserts a newline; Esc cancels; after the last task, focus jumps to the Send Responses button so the engineer can fire the whole batch with one more keystroke. Mouse path also auto-advances. Subtle hint row (`⏎ submit · ⇧⏎ newline`) under each open input teaches the shortcut.
+- **Collapsible "What we know" section** (#158) — TaskLane's facts list is now a collapsible section with per-session memory in `sessionStorage`. Auto-collapses on first render at ≥5 facts so Questions and Diagnostic Checks stay above the fold; engineer's explicit toggle always wins.
+- **Escalation Mode wedge** (#155) — when an engineer escalates, the senior tech who claims the session lands on a magic-moment handoff-context screen with the structured briefing visible in seconds (no scrolling, no chat re-read). Live SSE pushes new arrivals to anyone watching the queue, atomic claim resolves race conditions, the queue auto-excludes the claimed session, the claiming user retains chat ownership for AI briefings, and a new analytics endpoint tracks post-claim time-to-first-action so you can see real minutes recovered (paired with a manual baseline — see CURRENT_TASK.md two-metric framing).
+- **Suggested-fix "Awaiting verification" outcome** (#156) — when a fix needs external confirmation (client power-cycle, AD replication, license sync) you can park it in `applied_pending` instead of forcing a worked / didn't / partial verdict. The new PendingBanner shows the parked status with worked / didn't / update reason / dismiss actions. The "Still checking" nudge records pending with a reason instead of just silencing. Page-level Resolve auto-patches pending → success before the resolution flow opens; page-level Escalate intercepts pending the same way it intercepts verifying/partial. Resolution notes and escalation packages frame the pending state honestly (provisional fix; leading hypothesis with what's being waited on).

 ### Changed
+- **Assistant Chat session screen — UX overhaul** (#158, "impeccable" pass) — removed the duplicate "Suggested checks" chip strip in favor of the TaskLane as the single source of truth; added an inline `Next steps · N pending` cue above the latest action-bearing AI bubble; consolidated the session header to two visible primary actions (Resolve + Escalate) plus a kebab for Context / New Ticket / Update Ticket / Pause; centered the messages column to `max-w-3xl` to match the composer; unified chat-bubble radii to `rounded-xl`; dropped every banned decoration (3px side stripes, gradient surfaces, accent borderTop, backdrop blur, pulse rings, bordered avatar boxes) for a single decoration channel per surface; unified 14 distinct text sizes into a 5-step scale (10/11/12/13/14px); split the ambiguous `MessageCircleQuestion` icon into `Pencil` (write affordance for question Answer CTA) and `HelpCircle` (universal help icon for the per-check explainer); audited and dropped redundant `font-sans` classes across the screen.
+- **Suggested-fix banner ↔ script panel are now linked** (#158) — collapsing the ProposalBanner now also hides the InlineNoTemplateDialog / TemplateMatchPanel; dismissing the banner closes both surfaces. Recording any outcome on a fix (Dismiss, It worked, Didn't work, Mark partial, Waiting to verify) closes the script panel alongside the banner state transition.
 - **Edit Procedure page** — layout overhaul and color system refinements for better visual hierarchy
 - **Flows sidebar navigation** — collapsed to reduce visual noise; session recovery removed from library view
 - **Account settings page** — audit fixes for improved consistency and usability

 - **Tenant data boundaries** — all session and tree endpoints now return 404 (not 403) for cross-tenant access attempts to avoid confirming resource existence
 
 ### Fixed
+- **`ParameterizationPreview` over-highlight on short parameter values** (#158) — the tokenizer matched highlight values via raw substring with no word-boundary check, so a single-char value like `"D"` (a drive letter) lit up every capital D in identifiers like `Get-ADUser`, `Add-Type`, `Disable-`. Added a word-boundary guard that's conditional on whether the value itself starts/ends with a word character, so values with leading/trailing punctuation (e.g. `"D:\\Folder"`) still match cleanly when adjacent to whitespace.
 - **CRITICAL: Copilot tree query isolation** (#131) — user could access any tree UUID if known, exposing full tree structure to AI. Now scoped to current account with 404 for inaccessible trees.
 - **AI session search isolation** — search endpoint leaked other users' sessions via OR(user_id, account_id). Now restricted to current user only.
 - **Analytics endpoint isolation** — GET `/analytics/flows/{tree_id}` exposed session counts for any tree UUID. Now returns 404 if tree doesn't belong to requesting account.

+## Active Phase: Go-to-Market Validation (Pre-PMF) — Self-serve cutover (Phase O) in flight
+
+Self-serve signup backend (Phase 1) and frontend (Phase 2) are merged. Cutover (Phase O) is gated on manual ops: live-mode Stripe Dashboard config, Railway prod env vars, internal validation pass against prod test mode, then the public flag flip. Plan: `docs/superpowers/plans/2026-05-06-self-serve-signup-phase-2-frontend-cutover.md`.

+
+## Recently shipped (post-0.1.0.0)
+
+- **2026-05-07 — PR #164 (open)** Plan taxonomy reconciliation + `INTERNAL_TESTER_EMAILS` allowlist. Marketing surface (PricingPage, Stripe products) used `Starter / Pro / Enterprise` while backend was on `free / pro / team`, leaving `plan_billing` unseeded and `BillingPlan` schema accepting a literal that violated the FK. Migration `4ce3e594cb87`: rename `team` → `enterprise` in `plan_limits`, add `starter` row (caps interpolated between free and pro: `max_trees=10`, `sessions=75`, `ai=15/mo`), defensive update of any subscriptions on the `team` slug. Code rename across schemas, `Subscription` paid-plan checks, admin endpoints, and frontend `useSubscription`. Resource visibility (`Tree.visibility='team'`, `StepLibrary.visibility='team'`) is a separate domain and intentionally untouched. New `backend/scripts/sync_stripe_plan_ids.py` — idempotent upsert of `plan_billing` rows from Stripe products by exact name match, picks active monthly recurring price, leaves annual fields NULL by design. Test-mode `plan_billing` populated for all 3 tiers in dev. Phase O Task 46 allowlist: `INTERNAL_TESTER_EMAILS` env var (comma-separated) bypasses `SELF_SERVE_ENABLED=false` for specific authenticated users — `Settings.is_self_serve_active_for(email)` centralizes the check; `/config/public` returns `self_serve_enabled=true` for allowlisted authenticated callers; `/auth/register` allows allowlisted emails to register without invite code. New `get_current_user_optional` dep for endpoints that work both anonymous and authed.
+
+- **2026-05-06 — PR #163** Seed test users marked email-verified. Fixed seeded users showing the email verification banner in dev/test, blocking flows that gate on `email_verified=True`. Squash-merged into main as `dad5e1f`.
+
+- **2026-05-06 — PR #162** Self-serve signup Phase 2 (frontend cutover). 18 commits across Tasks 27–44 of the Phase 2 plan: backend remainders + frontend billing foundation + auth surfaces (OAuth + accept-invite + verify-email) + welcome wizard + dashboard redesign (TrialPill, NextStepCard, unified checklist) + public surfaces (`/pricing`, `/contact-sales`) + beta-signup deprecation. Single alembic head `c6cbfc534fad` (no new migrations in Phase 2). Squash-merged as `f1be3ab`.
+
+- **2026-05-?? — PR #161** Self-serve signup backend (Phase 1). `plan_billing` sibling table for Stripe + catalog metadata, `sales_leads` and `stripe_events` tables, `complimentary` status with `has_pro_entitlement`, `BillingService.start_trial` wired into `/auth/register`, `/billing/checkout-session`, Stripe webhook handler with idempotency via `stripe_events`, Google + Microsoft OAuth callbacks with `oauth_identities` linking, `require_verified_email_after_grace` + `require_active_subscription` guards, bulk-create + soft-revoke invite endpoints, account-invite email-match enforcement, pilot complimentary backfill, `accounts.team_size_bucket` + `primary_psa` for wizard. Squash-merged as `f918b76`.
+
+- **2026-05-02 — PR #159** In-product User Guides rewrite to Diátaxis how-tos. Replaced 15 feature-dump guides with 43 problem-oriented how-tos grouped under 10 categories. Dropped Maintenance Flows / AI Assistant / Flow Assist Sparkles guides (UI no longer exists). Renamed Step Library → Solutions Library. Authored 14 net-new how-tos for FlowPilot-era surfaces (tasklane keyboard flow, what-we-know, resolve, escalate, record-fix-outcome, post-docs-to-ticket, share-update, pause-and-leave, build-script-from-scratch, open-suggested-flow, pin-a-flow, invite-teammate, etc.). Schema additions: `category`, optional `relatedSlugs`. Browser-verified against engineer + owner login.
+
+- **2026-05-?? — PR #160** Post-PR-159 UI cleanup — sidebar IA + account redesign. Squash-merged as `a8b22cf`.
+
+- **2026-05-01 — PR #158** Session-screen UX impeccable pass + tasklane keyboard flow. Heuristic score 24/40 → 33/40 across five sub-passes (distill, quieter, layout, typeset, polish). Removed duplicate "Suggested checks" chip strip → TaskLane is the single source of truth; added inline `Next steps · N pending` cue on the latest action-bearing AI bubble; consolidated session header to Resolve + Escalate + ⋯ kebab; centered messages column to match composer; dropped all banned decorations (side stripes, gradient surfaces, backdrop blur, accent borderTop) for a single decoration channel per surface; unified 14 text sizes into a 5-step scale. TaskLane keyboard flow: Enter submits + auto-advances, Shift+Enter newline, Esc cancel, focus jumps to Send after the last task. Banner ↔ script-panel are now linked (collapse hides both, any outcome closes both). WhatWeKnow section is collapsible with `sessionStorage` memory + auto-collapse-at-5-facts. Side fix: ParameterizationPreview no longer over-highlights short parameter values (word-boundary check). Two backlog entries logged in `.ai/TODO.md`: ConcludeSessionModal multi-select and `bg-card-hover` Tailwind drift in CommandPalette.
+- **2026-05-01 — PR #156** Suggested-fix "Awaiting verification" outcome. Engineers can now park a fix in `applied_pending` (waiting on client power-cycle, AD replication, license sync, etc.) instead of forcing a synchronous worked/didn't/partial verdict. PendingBanner with worked / didn't / update reason / dismiss; nudge "Still checking" records pending with a reason; page-level Resolve auto-patches pending → success before the resolution flow opens; page-level Escalate intercepts pending. Migration `c0f3a4b7e91d` (`pending_reason` column + status CHECK constraint).
+- **2026-04-30 — PR #155** Escalation Mode wedge. Magic-moment handoff-context screen for senior pickup, live SSE escalation arrivals, post-claim time-to-first-action metric (`GET /analytics/flowpilot/escalations`), atomic role-gated claim with conflict resolution, queue self-exclusion, chat ownership extended to claimed sessions. The wedge for the first paying-customer push.

+This migration:
+
+  1. Defensively migrates any existing subscriptions on plan='team' to
+     plan='enterprise' (dev has zero such rows; prod is expected to have
+     none, but the UPDATE is safe and idempotent).
+  2. Renames the plan_limits row 'team' -> 'enterprise'. plan_billing
+     and plan_feature_defaults are FK-referenced but currently empty;
+     the rename works because PostgreSQL allows updating PK values when

+  3. Inserts a new plan_limits row for 'starter' between free and pro.

+"""In-memory pub/sub bus for live escalation events.

+Single-process, non-durable. When a handoff fires, every connected SSE
+subscriber for the same `account_id` receives the event. Subscribers come
+and go as senior techs open and close the EscalationQueue page.
+
+Pre-PMF scale (3 pilots × 5-20 techs/MSP = ~15-60 concurrent subscribers
+total, single Railway replica) makes in-memory the right call. When the
+deployment scales horizontally, swap this for Redis pub/sub or similar —
+the public surface (`publish` / `subscribe`) is intentionally narrow so
+the swap is local.
+
+Events are JSON-serializable dicts. `publish()` is non-blocking (drops the
+event if a subscriber's queue is full rather than back-pressuring the
+caller). `subscribe()` MUST be paired with `unsubscribe()` in a finally
+block, or you leak queues.

+that have one, and upserts plan_billing rows.
