docs(decisions): record plan-tier taxonomy centralization decision (Option B)

Captures the 2026-05-29 decision to derive admin plan dropdown + validation
from the plan_limits table rather than hand-duplicating the allow-list across
6+ sites. Triggered by the prod "AI sessions down" report that traced to the
admin dropdown still offering the dead 'team' slug. Adds the matching backlog
entry to TODO.md with duplication sites enumerated.

 # CURRENT_TASK.md
 
-**Task:** Add a fourth, non-terminal outcome to the suggested-fix banner — **Awaiting verification** (`applied_pending`). Today the verifying banner forces a synchronous verdict (worked / didn't / partial), but a lot of real fixes are async — engineer ran the script but is waiting on the client to power-cycle, AD replication, an O365 license sync. Without a fourth state the banner sits stale or the engineer guesses wrong.
+**Active task:** Phase O cutover for self-serve signup. All code blockers are now closed on `main`. Only user-side manual ops remain: apex DNS fix at Namecheap, Stripe Dashboard live-mode config (with the new `/contact` and `/policies` URLs surfaced in the business profile), Railway prod env vars, internal validation pass, public flag flip. See `.ai/HANDOFF.md` for the resume point.
 
-**Status:** ✅ **Engineering complete; PR #156 open.** Backend tests, prompt guardrail, frontend tsc/build clean; Alembic migration applies. Pending browser QA.
+## Recently shipped
 
-**Branch:** `feat/fix-pending-verification` (off `main` after the Escalation Mode merge).
-
-**PR:** https://gitea.resolutionflow.com/chihlasm/resolutionflow/pulls/156
-
-## What ships
-
-| Layer | Change |
-|---|---|
-| Schema | New `FixStatus="applied_pending"` + new `pending_reason` Text column on `session_suggested_fixes`. |
-| Migration | `c0f3a4b7e91d` — adds `pending_reason`, extends status CHECK constraint. |
-| API | `PATCH /suggested-fixes/{id}/outcome` accepts `applied_pending`, requires `notes`, stamps `applied_at` only (NOT `verified_at`). Pending in/out transitions allowed (parked, like partial). |
-| Generators | `resolution_note_generator` and `escalation_package_generator` system prompts handle the new status without real-looking examples; resolution note frames the fix as provisional; escalation package surfaces pending verification as the leading hypothesis with reference to what's being waited on. |
-| Frontend | New `BannerMode='pending'` + `PendingBanner` component (info-tone, mirrors `PartialBanner`) with worked / didn't / update reason / dismiss actions; "Waiting to verify…" overflow option in `VerifyingBanner`; nudge "Still checking" now records pending with a reason instead of just silencing; `AssistantChatPage` banner-mode derivation maps `applied_pending → 'pending'`; page-level Resolve/Escalate now handle pending honestly. |
-| Tests | 4 new integration tests in `test_fix_outcome_endpoint.py`: pending-requires-notes, pending stores reason + applied_at-not-verified_at, pending→success transition, pending_reason update on re-PATCH. 21/21 pass. Prompt anti-parrot guardrail passes. Frontend `tsc -b` and Vite build pass via Docker. |
-
-## Out of scope (intentionally)
-
-- Cross-session "Follow-ups" dashboard rollup. The chat-anchored `PendingBanner` is the per-session reminder. Add the dashboard surface only if engineers report losing track across multiple pending sessions.
-- Optional follow-up timer ("remind me in 30m"). Nice but not the wedge.
-
-## Resume point — DO THIS NEXT
-
-**Browser QA:** verify the new flow end-to-end in dev:
-1. Trigger a suggested fix, click Apply, then open the verifying banner overflow → "Waiting to verify…" → enter a reason → confirm `PendingBanner` renders with the reason.
-2. From `PendingBanner`, click "It worked" → confirm transition to terminal success and banner dismissal.
-3. From `PendingBanner`, click "Update reason" → confirm reason updates server-side.
-4. From `PendingBanner`, click "Dismiss" → confirm banner dismissal and no terminal timestamps.
-5. Trigger the nudge state (3+ post-apply messages) → click "Still checking" → enter a reason → confirm pending state takes over.
-6. From a pending fix, use page-level Resolve → confirm the fix is patched to `applied_success` before the resolution note.
-7. From a pending fix, use page-level Escalate → confirm the outcome intercept appears before the conclude modal.
-
-After QA passes, commit/push the local review fixes and merge PR #156.

-## Just-shipped (2026-04-30)

-**PR #155 — Escalation Mode wedge** merged into main as `ac42f97`. The wedge for ResolutionFlow's GTM (first paying-customer push). Senior tech sees structured handoff context in seconds via the magic-moment screen. Plan: [`docs/plans/2026-04-27-escalation-mode-wedge-design.md`](../docs/plans/2026-04-27-escalation-mode-wedge-design.md).
+- **2026-05-14 — PR #168** Session expiration policy + dashboard onboarding-CTA fix + welcome step-2 PSA CTA reshape. Merge-committed into main as `3a35121`. Three threads bundled on one branch (`feat/session-expiration-policy`):
+  - **Session expiration policy** (original branch scope): 3d idle / 14d absolute, per-account override, bulk revoke. New `AccountSecuritySettingsPage`, `RevokeSessionsModal`, `SessionExpiryToast`, `useAuthSessionExpiry` hook; backend dependencies in `accountSecurity.ts`.
+  - **Dashboard onboarding CTA fix** (`8d79dd9`): The "Start a session" CTAs on `NextStepCard` and `SetupChecklist` used to `<Link to="/">` while themselves rendered on `/`, so clicks were silent no-ops. Replaced with a `FOCUS_START_SESSION_EVENT` window event that `StartSessionInput` listens for — scrolls itself into view (top of viewport), focuses the textarea, pulses a blue ring 900ms. `NextStepCard` hides itself locally on click so the prompt doesn't linger while the user types.
+  - **Welcome step-2 PSA CTA reshape** (`dc88797`): Selecting a real PSA now swaps `[Continue] [Skip]` for `[Connect <PSA> now] [Connect later] [Skip this step]`. Primary blue button saves `primary_psa` and routes to `/account/integrations`; "Connect later" saves and continues to step 3. **Pre-existing bug fixed**: the old subtle "Connect now →" link never persisted `primary_psa` before navigating. Now it does. "No PSA yet" / no-selection states still show the original single Continue.
+- **2026-05-14 — PR #166** Docs/handoff doc updates carrying forward PR #164/#165 state and EIN blocker. Squash-merged into main as `fe0e692`.
+- **2026-05-12 — PR #167** `backend/scripts/create_site_admin.py` site-wide super-admin bootstrap script. Squash-merged into main as `e50a215`. Idempotent CLI, three modes (`--send-reset`, `--print-reset`, `--promote-only`). Uses `ADMIN_DATABASE_URL` (BYPASSRLS). User confirmed end-to-end success against prod via `railway ssh` 2026-05-12 evening.
+- **2026-05-12 — PR #165** Legal/contact pages for Stripe site review. Squash-merged into main as `ba45cfe`. Three new SPA pages: `/policies` (consolidated Customer Policies — refunds, cancellation, U.S. legal/export restrictions, promotional terms; anchor IDs per subsection), `/contact` (phone (470) 949-4131, support/sales/billing/security inboxes, response-time SLAs), `/promotions` (stub satisfying Policies §6.2). New `MarketingFooter` component (`components/common/MarketingFooter.tsx`) extracted from inline landing footer; mounted on `/landing`, `/pricing`, `/contact-sales` so all four legal links (Privacy/Terms/Policies/Contact) are reachable from every marketing surface. Component reuses existing `landing-footer*` CSS — must be inside a `.landing-page` wrapper (documented in JSX comment). Privacy and Terms closing sections updated to point at `/contact` + `/policies` with correct per-area inboxes; stale `hello@` mailto removed everywhere. Mailing address left as TODO comments in both `ContactPage.tsx` and `PoliciesPage.tsx`, rendered publicly as "available on request" until P.O. Box is purchased. tsc + eslint clean.
+- **2026-05-08 — PR #164** 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:

+  - 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.

+## 2026-05-29 — Single source of truth for plan-tier taxonomy (derive admin UI + validation from `plan_limits`)
+
+**Context:** A prod report ("AI sessions aren't working") traced to the owner account having no paid plan (AI is plan-gated), compounded by a real bug: the admin "Change Plan" dropdown ([`AccountDetailPage.tsx:443-445`](../frontend/src/pages/admin/AccountDetailPage.tsx)) still offered the dead `team` slug (renamed to `enterprise` in migration `4ce3e594cb87`, 2026-05-07) and omitted `starter`/`enterprise`. Selecting "Team" 400s against the hardcoded allow-list in [`admin.py:994`](../backend/app/api/endpoints/admin.py#L994). The dropdown was missed during the 2026-05-07 taxonomy reconciliation because the allowed-plan list is hand-duplicated across ≥6 backend + frontend sites. Second taxonomy-drift incident.
+
+**Decision:** Option B — make `plan_limits` the single source of truth: admin dropdown + pricing/checkout derive plan options from a plans endpoint (filter `is_public`, order by `sort_order`, label from `display_name`), and backend validation checks against actual `plan_limits` rows rather than a hardcoded tuple. Implementation deferred (active work is on another branch); fully specced in [TODO.md](TODO.md). A trivial dropdown-options fix may land first to unblock the admin tool.
+
+**Rejected:** Option A (patch only the `AccountDetailPage` dropdown). Fixes the symptom but leaves the duplication that has now caused two drift incidents — and there is no outage forcing a minimal diff (bug is admin-only and was already worked around via direct Pro assignment). Conflicts with the repo principle "prefer correct architecture over minimal diff."
+
+**Consequences:** New plan tiers become a data change (a `plan_limits` row) instead of a multi-file code edit; UI and validation can no longer drift from the catalog. Requires a public-plans read endpoint (or extending billing state) consumed by the admin UI + pricing page. The `'team'` visibility string (`Tree.visibility` / `StepLibrary.visibility`) is a separate domain and is explicitly out of scope.

+
+## 2026-05-28 — Scope Anthropic structured outputs to flat-array JSON only
+
+**Context:** Optimizing the existing Claude API usage (no model change). The Anthropic path in `generate_json` (`ai_provider.py`) had no equivalent to the Gemini path's `response_mime_type="application/json"` — it prompted for JSON and relied on downstream defenses: `_strip_markdown_fences` (ai_fix), `parse_llm_json` (knowledge_flywheel), and `_try_repair_json` (kb_conversion, which balances unclosed braces on truncated output). Anthropic structured outputs (`output_config.format` with a JSON schema) guarantee valid, parseable JSON and would eliminate those band-aids. The question was which of the four `generate_json` call sites can adopt it.
+
+Structured outputs has hard schema limits: **no recursive schemas**, and **every object must set `additionalProperties: false`** (so the schema must enumerate exactly the fields the model emits — a superset is impossible, an omission makes a field unproducible). Tracing the call sites against those limits:
+
+- **kb_conversion** → output is `{title, description, nodes: [...]}` / `{...steps[], intake_form[]}` — **flat arrays**, references by `next_node_id`/id, no nesting. Expressible.
+- **ai_fix** → returns a fixed *node that is itself a subtree*; `_find_node_by_id` recurses `node["children"]` and the prompt requires decision nodes to have ≥2 children. **Recursive, arbitrary depth.**
+- **knowledge_flywheel flow-gen** → emits `tree_structure`, a decision-tree root with nested `children`/`options`, persisted as an opaque blob.
+- **knowledge_flywheel enhancement** → flat `new_nodes[] + modified_options[]`; expressible but low-frequency and only fence-stripped.
+
+**Decision:** Apply structured outputs to **flat-array outputs only** — i.e. `kb_conversion`. Wired via an optional `schema=` param on `AIProvider.generate_json` (`None` = legacy prompt-only behavior; Anthropic maps it to `output_config.format`, Gemini ignores it), with the two KB schemas + `_schema_for_target_type()` in `kb_conversion_service.py`, gated behind `settings.AI_KB_CONVERT_STRUCTURED_OUTPUT` (default **False**) pending a live constrained-decoding smoke-test in staging. The robustness fixes that motivated the work — `_extract_text_from_response` (skip non-text blocks, log `max_tokens`/`refusal`, raise on no-text) — live in the shared provider, so **all four** callers already benefit regardless of schema adoption.
+
+**Rejected:**
+- **Forcing schemas on ai_fix / flow-gen.** Their outputs are recursive/nested decision trees; a bounded-depth schema would reject valid deeper trees and break generation. Wrong architecture for marginal/zero benefit (flow-gen's tree is stored as a blob, never schema-validated downstream).
+- **Wiring the flywheel enhancement site.** Flat and technically expressible, but low call frequency and only fence-stripping today — marginal benefit against the risk of a blind (un-live-tested) `additionalProperties: false` schema.
+- **Deleting the fence-strip / repair helpers now.** `_strip_markdown_fences` / `parse_llm_json` must stay — they protect the recursive paths that can't use schemas. Only `_try_repair_json` (kb-only) becomes removable, and only *after* the flag is validated in staging.
+
+**Consequences:**
+- Structured outputs is the tool for flat JSON; recursive decision-tree outputs are excluded by design. New flat-JSON `generate_json` callers can opt in via `schema=`; recursive ones should not.
+- `AI_KB_CONVERT_STRUCTURED_OUTPUT` must be smoke-tested against the live model (both target types) before production enablement. Open risk: whether Anthropic accepts optional (non-`required`) fields — if not, the schemas need every field in `required` with nullable types. The flag makes this fully reversible.
+- Deferred cleanup: once the flag is validated, remove only `_try_repair_json` from the kb_conversion Anthropic path; leave the fence-strippers.
+- Work lives on branch `feat/ai-structured-outputs` (commits `84a02a5`, `1388357`), based on `design/l1-workspace`.

+## 2026-05-13 — Session expiration policy: 3d idle / 14d absolute defaults + per-account override
+
+**Context:** User report: "I login to ResolutionFlow and never have to log back in." Investigation found refresh tokens at `REFRESH_TOKEN_EXPIRE_DAYS=7` with JTI rotation (`security.py:36`) — every `/auth/refresh` minted a fresh 7-day window. Net effect: a sliding 7-day session with no absolute cap. Visit once a week, logged in forever. Acceptable for pilot but not for MSP buyers whose SOC2 / cyber-insurance auditors require enforced session timeouts. Required for the same Phase O launch readiness as the other gates already in flight.
+
+**Decision:** Two-window model snapshotted into the refresh JWT at login. Defaults to Strict (3-day idle, 14-day absolute), bounded by env-var system min/max. Per-account override via two new `accounts` columns (NULL = use system default). Owner-only `GET/PATCH /accounts/me/security` endpoint with effective-value validation (partial-override case caught at the app layer because the DB CHECK can't see Settings). Sibling `POST /accounts/me/security/revoke-sessions` for `all|others`-scoped bulk revocation. Frontend: Strict/Standard/Custom presets, active-users list (name + email + last-login-ago), differentiated SessionExpiryToast (idle = warning amber with "Stay signed in" → `/auth/refresh`; absolute = info cyan, informational only), cyan info-tone banner on `/login?reason=session_expired`, auto-redirect after scope=all bulk-revoke. Error-detail taxonomy on the wire: `session_expired_idle`, `session_expired_absolute`, `invalid_refresh_token`. Grandfather path: legacy refresh tokens (no `auth_time` claim) get one free rotation under the new policy. Atomic-revoke-then-check on `/auth/refresh` so absolute-expired tokens can't be replayed.
+
+8 commits on `feat/session-expiration-policy` branch (`92fa3bc` → `c7cd711`), ~1300 LoC backend + frontend including 28 backend tests. Plan + design review at `docs/plans/2026-05-13-session-expiration-policy.md` (initial design score 4/10 → final 9/10 via `/plan-design-review`; 7 design decisions locked).
+
+**Rejected:**
+- **Idle-only or absolute-only enforcement.** Idle without absolute is the current broken state (sliding forever). Absolute without idle is too strict — kicks users out daily.
+- **Hard cutover on deploy (SECRET_KEY rotation).** Forces every pilot to log in again immediately; high support cost. Grandfather path is friendlier and adds ~50 lines of code.
+- **Distinguish `session_revoked_by_admin` from `invalid_refresh_token` on the wire** for users whose sessions were killed via bulk-revoke. Requires tracking revocation reason per `refresh_tokens` row. Not worth the complexity for v1 — affected users see they're logged out, same as any other revoke.
+- **Per-user device list with per-device revoke.** Refresh tokens don't carry device/user-agent metadata today. Account-wide bulk revoke covers the breach-response use case; per-device is a follow-up if pilots ask.
+- **"Loose" preset (90d).** Strict default suggests we shouldn't ship a one-click loose option. Owners who want a loose policy can use Custom and own the choice explicitly.
+- **Always-required `idle_minutes`+`absolute_minutes` (XOR-NULL invariant).** Forces owners who only want to override idle to also re-declare the absolute window, leaking the system default into account data. Partial overrides allowed; validated at the app layer against current defaults.
+- **Reveal-on-Custom UI for the minute inputs.** Hidden-by-default-reveal-on-radio shifts page layout when Custom is selected. Always-visible-but-disabled is more stable and previews the Custom interaction.
+- **Modal-stays-open-success-state for scope=all bulk-revoke.** User preferred auto-redirect-with-toast (more standard SaaS pattern); the toast acts as the success acknowledgment before /login loads.
+
+**Consequences:**
+- "Logged in forever" is fixed. Every user sees a hard 14-day re-auth at minimum (3-day idle in practice for typical usage).
+- Account owners get a complete self-service surface for policy + bulk session control. New `/account/security` route, owner-gated.
+- Audit-log entries on both mutations: `account.session_policy_update` and `account.sessions_revoked_bulk`. SOC2-ready.
+- Frontend `idle_expires_at` + `absolute_expires_at` flow through the entire auth surface (`Token`, `OAuthCallbackResponse`, `authStore`, persistence). `useAuthSessionExpiry` hook is the single source for "is the session about to end."
+- Future improvements (filed as follow-ups in plan §9): per-user device list (requires `refresh_tokens.last_used_at` column), super-admin global ceiling UI, per-user policy. None block current shipping.
+- Cyan info-tone banner on `/login` is the first of its kind in the app; sets precedent for future neutral system messages.

+## 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.

-**Active task:** Suggested-fix `applied_pending` outcome. Branch: `feat/fix-pending-verification`. PR #156 open; review fixes applied locally and ready for browser QA, then commit/merge.
+**Active task:** Phase O cutover for self-serve signup. All code blockers remain closed on `main`. **Still blocked on Stripe live-mode activation — root cause is EIN, not code.** User does not yet have an EIN for ResolutionFlow, LLC; Stripe requires a tax ID for live-mode activation. EIN application via IRS.gov was scheduled for 2026-05-13 — confirm status at next session start. Mailing-address decision (carried forward from 2026-05-12): user enters home address into Stripe's **private** business profile temporarily so live-mode isn't blocked on the P.O. Box; public `ContactPage`/`PoliciesPage` mailing-address TODOs stay "available on request" until the P.O. Box is purchased. Stripe accepts an address update later without re-verification. Apex DNS at Namecheap is still missing (separate user-side issue, only matters once Stripe runs site-verification). Nothing on the code side blocks live-mode flip.
 
-**Just-merged:** PR #155 (Escalation Mode wedge) merged into main as `ac42f97`.
+**Bug-pending-capture item (2026-05-12) — likely resolved:** Prior session noted "user reported finding a bug, will send screenshot next session." This session surfaced two concrete UX bugs that were fixed and merged (PR #168): the dashboard "Start a session" CTA was a dead link, and welcome step-2's PSA setup had a near-invisible "Connect now →" link that didn't even persist `primary_psa`. **Confirm with user at next session start whether the screenshot bug was one of these or something else still pending.**
 
 ## Where this session ended
 
-PR #156 was reviewed for missed bugs and three fixes were applied:
+Two PRs merged into main:
 
-1. Page-level **Resolve** now treats `applied_pending` as a verifying state and patches the fix to `applied_success` before opening the resolution flow, avoiding provisional notes on a resolved session.
-2. Page-level **Escalate** intercept now catches `applied_pending` as well as verifying/partial, so a pending fix cannot bypass outcome capture before handoff. Intercept copy was generalized from "Verifying state" to "still needs an outcome."
-3. `PendingBanner` now includes a **Dismiss** action, matching the PR body and backend's allowed pending → dismissed transition.
-4. Real-looking pending examples were removed from `resolution_note_generator` and `escalation_package_generator` system prompts to stay aligned with the prompt anti-parrot guardrail.
+- **PR #166** (`fe0e692`) — docs/handoff doc updates from prior session. Squash-merged 2026-05-14.
+- **PR #168** (`3a35121`) — session expiration policy + dashboard NextStep CTA fix + welcome step-2 PSA CTA reshape. Merge-committed 2026-05-14. Three notable additions:
+  - `feat(dashboard)` `8d79dd9` — The "Start a session" CTAs on NextStepCard and SetupChecklist used to `Link`-navigate to `/`, leaving the user on the same page (the StartSessionInput lives on the dashboard) with no visible response. Replaced with a `FOCUS_START_SESSION_EVENT` window event the StartSessionInput listens for: scrolls input to viewport top (`scrollIntoView({block:'start'})`), focuses the textarea (with `preventScroll:true` so it doesn't fight the smooth scroll), pulses a `rgba(96,165,250,…)` ring for 900ms. NextStepCard hides itself via local `locallyHidden` state on click so the user isn't double-prompted while typing. SetupChecklist gets the same event-dispatch treatment for its `ran_session` row.
+  - `feat(welcome)` `dc88797` — Welcome step-2 PSA CTA reshaped. Selecting a real PSA now swaps the single Continue + tiny "Connect now →" link for an explicit two-button choice: `Connect <PSA> now` (primary, blue — saves `primary_psa` then routes to `/account/integrations`) and `Connect later` (secondary outlined — saves `primary_psa` then continues to step 3). **Important pre-existing bug fixed**: the old subtle Link never actually persisted `primary_psa` before navigating away. Both new buttons do. "No PSA yet" and no-selection states still show the original single Continue. Skip-this-step and Skip-the-rest unchanged. Existing tests pass without edits (testids `welcome-step-2-connect-now` and `welcome-step-2-continue` reused).
+  - `docs:` `e5b2624` — added `docs/plans/2026-05-13-public-landing-routing-refactor.md`, `docs/architecture/` reports (god-node map + report 2026-05-06, workflows.json/html, workflows-analysis.html), `docs/tutorials/build-a-page.md`, and `abc-feat-self-serve-signup-phase-2-design-20260507-112020.md` at repo root.

+Working tree clean except those persistent untracked items (intentionally left for issue #172).

+## Resume point
 
-## Watch-outs
+**First thing next session:**
 
-- Dev stack: backend `:8000`, frontend `:5173`, postgres `:5433` (docker-compose). HMR works. On this host use `docker exec` for Python/npm commands; see `.ai/PROJECT_CONTEXT.md`.
-- Test users (Acme MSP, password `TestPass123!`): `engineer@resolutionflow.example.com`, `teamadmin@resolutionflow.example.com`.
-- Multi-head alembic state on main is pre-existing (heads `070`, `c0f3a4b7e91d`, `024`); not introduced by this work but worth knowing if `alembic upgrade head` complains — use `upgrade heads` (plural).
-- `pending_reason` is preserved as audit trail when an engineer advances pending → success/failed/dismissed; it is not auto-cleared. Intentional.
-- Working tree also has documentation edits in `.ai/PROJECT_CONTEXT.md` and `AGENTS.md` describing Docker exec commands. Those were not part of the feature fix but should be preserved.
+1. Confirm with user whether the "bug-pending-capture" screenshot bug from 2026-05-12 was one of the two PR #168 fixes or something else still pending.
+2. Check EIN application status (filed 2026-05-13 via IRS.gov). If granted, unblocks the Phase O Stripe live-mode setup chain.
+
+After that — **Phase O manual ops, all user-side, all gated on EIN landing first:**
+
+1. **EIN application status check** (user, applied 2026-05-13).
+2. **Stripe Dashboard live-mode** (once EIN is in hand):
+   - 3 Products (Starter, Pro, Enterprise). 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.
+   - **Business profile fields**: Customer service URL `https://resolutionflow.com/contact`. Refund/cancellation policy URL `https://resolutionflow.com/policies`. Terms `https://resolutionflow.com/terms`. Privacy `https://resolutionflow.com/privacy`. Phone `(470) 949-4131`. Mailing address = user's home address temporarily (private Stripe field; swap to P.O. Box later without re-verification). EIN = the newly-issued tax ID.
+3. **Apex DNS fix at Namecheap** (re-add `@` ALIAS → `c9g7uku8.up.railway.app`, or re-add apex as a Railway custom domain). Becomes the next blocker once Stripe runs site-verification.
+4. **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.
+5. **Bootstrap prod super-admin** via `create_site_admin.py` (PR #167) — already done end-to-end on prod per 2026-05-12 user confirmation. Re-runnable if needed.
+6. **Sync Stripe → DB**: `railway run python -m scripts.sync_stripe_plan_ids` (or via `railway ssh`). Verify `plan_billing` rows have `sk_live_*` price IDs.
+7. **Internal validation (Phase O Task 46)**: 9 scenarios with internal testers whose emails match `INTERNAL_TESTER_EMAILS`.
+8. **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.
+
+## Open issues from prior session (non-code, user-side)
+
+- **Apex DNS missing.** `resolutionflow.com` (apex) returns no A/CNAME at the authoritative DNS (Namecheap). When `www` was reconfigured in Railway, the apex record got dropped from the zone. `www` works (cert provisioned 2026-05-08 01:40 UTC). User to re-add apex record at Namecheap (ALIAS `@` → `c9g7uku8.up.railway.app`) or re-add the apex as a Railway custom domain. 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.
+
+## Carry-forward
+
+- Annual pricing intentionally NOT implemented — user wants exit flexibility. Schema columns preserved as nullable. `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 now at `docs/` root (`abc-feat-self-serve-signup-phase-2-design-20260507-112020.md`) as of this session. NOT yet adopted as roadmap — gated on 3 cold calls with external Directors of Onboarding.
+- Mailing address fill-in: search for `TODO: replace with full mailing address` in `frontend/src/pages/ContactPage.tsx` and `frontend/src/pages/PoliciesPage.tsx` (one each) once P.O. Box is purchased.
+- `backend/scripts/create_site_admin.py` is the durable site-admin bootstrap tool — idempotent. Three modes: `--send-reset`, `--print-reset`, `--promote-only`. Run from inside the deployed backend container via `railway ssh`.
+- Bot-crawlability of legal pages: still SPA-rendered. Stripe didn't enforce content scraping last time (issue was DNS). If a future vendor review flags it, pre-render with `vite-plugin-prerender-spa` (~half day).
+- 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`.
+- **Branch hygiene note (process learning):** PR #168 ended up bundling unrelated work — session expiration policy (the original scope of `feat/session-expiration-policy`) plus dashboard CTA fixes plus welcome step-2 reshape. The mixed scope was deliberate (user wanted it on the same PR), but worth flagging for future PRs: if onboarding-UX work continues, branch it separately from auth/session work.

+## 2026-05-14 ~04:00 UTC — Claude — PR #166 + #168 merged; dashboard CTA bug fixed; welcome step-2 PSA CTA reshaped
+
+**Accomplished:**
+
+- User reported the "Start a session" CTA on the dashboard onboarding card doing nothing after completing the welcome wizard. Root cause: `NextStepCard.tsx:80-82` had `ctaPath: '/'` and the card itself only renders on the dashboard at `/`. Clicking `<Link to="/">` while already on `/` is a react-router no-op. Same dead-link in `SetupChecklist.tsx` for the `ran_session` row.
+- Designed and built the fix collaboratively (user wanted scroll-to-input + visual pulse rather than auto-navigate to `/pilot` or just hiding the card):
+  - Added `FOCUS_START_SESSION_EVENT = 'rf:focus-start-session'` window event exported from `StartSessionInput.tsx`. The component listens via `useEffect`, on dispatch calls `wrapperRef.current?.scrollIntoView({behavior:'smooth', block:'start'})`, focuses the textarea with `preventScroll:true` (so it doesn't fight the smooth scroll), and sets a 900ms `nudge` state that swaps the inner wrapper's `focus-within:` ring classes for a louder `ring-2 ring-[rgba(96,165,250,0.35)] shadow-[0_0_0_6px_rgba(96,165,250,0.12)]`. Added `scroll-mt-6` to the outer ref'd div so the input doesn't hug the very top edge.
+  - `NextStepCard.tsx` — branched on `next.key === 'ran_session'`. Render a `<button>` that dispatches the event AND sets a new `locallyHidden` useState so the card disappears immediately on click (without calling the persisting `dismissOnboarding` API — that would kill all future onboarding nudges). All other CTAs keep the original `Link` element. Tests pass without changes (assertions only check text + testid).
+  - `SetupChecklist.tsx` — same `ran_session` branch (the checklist had the same dead-link bug if the user expanded "Show all setup steps").
+- User then asked about the welcome wizard PSA flow — "is it supposed to take me to set up ConnectWise if I keep clicking next after picking it?" Read `WelcomeStep2.tsx`: the spec was intentionally "just pick what you use, we'll wire it up later" with a `text-xs text-muted-foreground` "Connect now →" link as the only credential-setup entry. The link was visually near-invisible AND had a bug: it was a `<Link to="/account/integrations">` that navigated WITHOUT calling `onboardingApi.updateStep`, so `primary_psa` was never persisted if the user clicked it.
+- Proposed three fix options; user picked option 2 (explicit two-button branch). Implemented in `WelcomeStep2.tsx`:
+  - New `handleConnectNow` handler that calls `onboardingApi.updateStep({step:2, action:'complete', data:{primary_psa}})` then `navigate('/account/integrations')`. New `submitting === 'connect-now'` state value.
+  - When `showConnectNow` (real PSA selected): action row renders `[Connect <PSA> now (primary)] [Connect later (secondary)] [Skip this step (tertiary)]`. Reused the old `welcome-step-2-connect-now` testid on the new primary button. "Connect later" reuses the `welcome-step-2-continue` testid + handleContinue. PSA label derived dynamically from `PSA_OPTIONS`.
+  - When 'none' or no selection: original `[Continue] [Skip this step]` preserved.
+  - Removed the import of `Link` from `react-router-dom` and the entire `showConnectNow && <Link>` block.
+- All existing tests pass unchanged (`tsc --noEmit` clean, locally; vitest blocked by root-owned `node_modules/.vite-temp` — same env issue noted previously; CI ran the suite green on the PR).
+- Committed in two logical commits onto current branch (`feat/session-expiration-policy`): `feat(welcome): two-button PSA CTA in step-2` (`dc88797`) and `docs: add architecture reports, public-landing routing plan, build-a-page tutorial, self-serve signup phase-2 design` (`e5b2624`). Pushed. PR #168 CI ran green across `CI/backend`, `CI/frontend`, `CI/e2e`. PR #166 merged first (HTTP 200), then PR #168 once CI cleared (HTTP 200). `main` now at `3a35121`.
+- Filed two issues for session leftovers:
+  - **#171** — Test coverage for the new `welcome-step-2-connect-now` path (existing tests still pass but don't exercise the new save + redirect behavior).
+  - **#172** — Repo hygiene: add `core.[0-9]*` and `**/.remember/` to `.gitignore`, delete the three 20MB core dumps + `docs/architecture/.remember/`.
+
+**Left for next session:**
+
+- Confirm with user whether the "bug-pending-capture" item from 2026-05-12 HANDOFF was one of the two fixes above (dashboard CTA dead-click, welcome step-2 ConnectWise confusion) or a third bug still pending. Likely covered, but worth asking.

+- Issues #171 and #172 sitting in the backlog when there's time.

+## 2026-05-12 ~06:30 UTC — Claude — PR #167 (site-admin bootstrap script) merged; bug pending capture
+
+**Accomplished:**
+
+- User reported being unable to log into prod with `admin@resolutionflow.example.com` — that's the dev seed email (`.example.com` is a documentation TLD), only present in dev. Prod has no admin user at all because `seed_test_users.py` doesn't run in prod, self-serve is still gated, and even when it flips on signup creates `owner` roles not `super_admin`.
+- Designed and built `backend/scripts/create_site_admin.py` — idempotent CLI script for creating or promoting a site-wide super-admin on any environment. Three modes: `--send-reset` (mails reset link), `--print-reset` (stdout reset link), `--promote-only` (promote existing user without creating). Creates an `Account` first, then a `User` with `is_super_admin=true`, `account_role='owner'`, `email_verified_at` stamped at creation, `password_hash=NULL` (forces the reset flow on first login). Uses `ADMIN_DATABASE_URL` (BYPASSRLS) — required because `users` is RLS-enabled and the script has no tenant context at bootstrap. Reset token mints via existing `create_password_reset_token` helper, hashes JTI into `password_reset_tokens` row matching the `/auth/password/forgot` shape.
+- Smoke-tested all three paths in the dev container before pushing: fresh create on a new email (Account + User + reset URL emitted), idempotent re-run on same email (SKIP message + new reset URL), `--promote-only` on a user with `password_hash=NULL` (promotes + issues reset). Cleaned up the dev test row + account afterwards.
+- Initial bug: had `used: false` in the `password_reset_tokens` INSERT — actual column is `used_at` (nullable timestamp, NULL means "not used"). Fixed before pushing.
+- PR #167 opened, CI green, squash-merged into main as `e50a215`. Remote branch `feat/site-admin-script` auto-deleted.
+- User confirmed end-to-end success on prod via `railway ssh --service=<backend>` then `python -m scripts.create_site_admin ...` ("we're good now"). Specific service name not captured. First prod super-admin row now exists in the prod DB.
+- Stripe live-mode activation block traced to EIN, not code (user does not yet have an EIN for ResolutionFlow, LLC). Applying via IRS.gov 2026-05-13. Mailing-address decision: home address into Stripe's **private** business profile temporarily so live-mode isn't blocked on the P.O. Box; public `ContactPage`/`PoliciesPage` stays "available on request". Stripe accepts address update later without re-verification.
+- PR #166 (docs handoff for PR #164/#165 merges + EIN decision) still open from earlier in this same session — was never merged. This entry rebases the docs branch onto current main (which now includes PR #167) and adds the PR #167 narrative + bug-pending state so a fresh session has the full picture in one merge.
+- User reported finding a bug in a UI surface but did not provide details — planning to send a screenshot via the VS Code extension GUI in the next session (CLI is unreliable for them). Next session: ask for the screenshot at session start, then triage.
+
+**Left for next session:**
+
+- Get the bug screenshot from the user, triage, fix or scope.
+- Otherwise everything that was on the prior entry's left-for-next-session still stands: EIN application Tuesday 2026-05-13, then Stripe live-mode setup, apex DNS at Namecheap, Railway prod env vars, internal validation, flag flip.
+
+**Files touched (all merged to main via PR #167 squash `e50a215`):** `backend/scripts/create_site_admin.py` (new, ~270 lines including docstring). Plus `.ai/HANDOFF.md`, `.ai/SESSION_LOG.md` on `docs/handoff-pr-165-merge` (PR #166, awaiting merge).
+
+---
+
+## 2026-05-12 05:30 UTC — Claude — PR #164 + #165 merged; Stripe activation reported blocked
+
+**Accomplished:**
+
+- Resumed from compacted context. Confirmed PR #164 (`feat/billing-plan-taxonomy`, head `2c9f5e9`) was already CI-green at session start and squash-merged into main as `3f04911` earlier in the session (occurred pre-compaction; reflected in the prior HANDOFF revision). Branch auto-deleted on remote.
+- User raised the legal/contact pages question in conversation. Verified existing state of `frontend/src/pages/{PrivacyPage,TermsPage}.tsx` — both already contain real, dated content (last updated 2026-03-21) but are SPA-rendered. Discussed Stripe's site-review needs with the user and agreed to build a consolidated Customer Policies page plus a Contact page (now that the user has a business phone number) plus a Promotions stub to satisfy Policies §6.2 cross-reference. User authorized the work.
+- Built PR #165 (`feat/stripe-legal-pages`, head `545b2ad`):
+  - **`/policies` — `frontend/src/pages/PoliciesPage.tsx`** (new). Consolidated Customer Policies doc, 8 sections with anchor IDs per subsection so Stripe (or a support email) can deep-link: customer service contact (with phone (470) 949-4131), return policy (n/a — SaaS), refund / dispute policy, cancellation policy, U.S. legal and export restrictions (Georgia governing law, OFAC / BIS compliance, sanctioned-jurisdiction exclusion), promotional terms (general + cross-ref to `/promotions`), changes-to-policies, relationship-to-other-agreements. Mailing address left as in-source `TODO` comment, rendered publicly as "available on request — email support@" until P.O. Box is purchased.
+  - **`/contact` — `frontend/src/pages/ContactPage.tsx`** (new). Phone **(470) 949-4131**, all four inboxes (`support@`, `sales@`, `billing@`, `security@`), response-time SLAs, mailing-address placeholder, link to `/contact-sales` for the lead-gen Calendly flow (distinct surface — kept both routes intentionally).
+  - **`/promotions` — `frontend/src/pages/PromotionsPage.tsx`** (new). One-paragraph stub stating no promotions currently active. Will be appended to when offers run; satisfies Policies §6.2's cross-reference.
+  - Routes wired in `frontend/src/router.tsx` as 3 new public lazy-loaded routes alongside existing `/privacy`, `/terms`, `/pricing`, `/contact-sales`.
+  - **`MarketingFooter` — `frontend/src/components/common/MarketingFooter.tsx`** (new, second commit). Extracted from the inline landing footer (26 lines → 1 line at the call site). Mounted on `/landing`, `/pricing`, `/contact-sales` so all four legal links (Privacy / Terms / Policies / Contact) are reachable from every marketing surface — including the page Stripe's reviewer spends the most time on (`/pricing`). Reuses existing `landing-footer*` CSS in `frontend/src/styles/landing.css` — must be rendered inside a `.landing-page` wrapper because `--lp-*` vars are scoped there (documented in a JSX comment). All three current call sites already wrap in `.landing-page`, so landing renders pixel-identically and the two new mount sites match.
+  - **Privacy and Terms closing sections** updated to point at `/contact` + `/policies` with correct per-area inboxes (`security@` for Privacy, `support@` for Terms). Stale `hello@resolutionflow.com` mailto removed everywhere.
+- `tsc --project tsconfig.app.json --noEmit` clean, `eslint` clean. Local `vite build` and `tsc -b` blocked by root-owned `node_modules/.tmp` and `node_modules/.vite-temp` cache directories — CI rebuilds from a clean env and was green.
+- PR #165 opened at `gitea.resolutionflow.com/chihlasm/resolutionflow/pulls/165`, CI passed, squash-merged into main as `ba45cfe`. Remote branch `feat/stripe-legal-pages` auto-deleted.
+- User reports continued trouble activating Stripe live mode. After follow-up: the real blocker is the EIN — ResolutionFlow, LLC does not have one yet, and Stripe requires a tax ID before it will activate live mode. User is applying via IRS.gov on 2026-05-13. Updated HANDOFF.md to remove the earlier speculation list and record EIN as the named blocker, with the P.O. Box / mailing address called out as the likely-next blocker (Stripe live-mode also requires a business mailing address). Apex DNS at Namecheap is still pending but only matters after the business profile is accepted (site verification is a downstream step).
+- Mailing-address decision: user is going with the home-address-temporarily approach for Stripe so live-mode isn't blocked on the P.O. Box. Home address goes into Stripe's **private** business profile only — the **public** `TODO: replace with full mailing address` in `ContactPage.tsx` and `PoliciesPage.tsx` stays as "available on request" until the P.O. Box is purchased. Stripe accepts updating the address later without re-verification, so swapping in the P.O. Box when it arrives is non-disruptive.
+
+**Left for next session:**
+
+- Check in on whether the EIN application went through and whether the P.O. Box / mailing address is sorted. Both are pure user-side ops; no code work to do until Stripe accepts the business profile.
+- Once Stripe is activated: Stripe Dashboard live-mode product/price/webhook setup, Railway prod env vars, `railway run python -m scripts.sync_stripe_plan_ids` against prod, 9-scenario internal validation, flag flip.
+- Apex DNS at Namecheap (still missing; only matters once Stripe runs its site-verification step).
+- Mailing address TODO in `ContactPage.tsx` and `PoliciesPage.tsx` (one each) — fill in when P.O. Box is purchased.
+
+**Files touched (all merged to main via PR #165 squash `ba45cfe`):** `frontend/src/pages/ContactPage.tsx` (new), `frontend/src/pages/PoliciesPage.tsx` (new), `frontend/src/pages/PromotionsPage.tsx` (new), `frontend/src/components/common/MarketingFooter.tsx` (new), `frontend/src/router.tsx`, `frontend/src/pages/LandingPage.tsx`, `frontend/src/pages/PricingPage.tsx`, `frontend/src/pages/ContactSalesPage.tsx`, `frontend/src/pages/PrivacyPage.tsx`, `frontend/src/pages/TermsPage.tsx`. Plus `.ai/HANDOFF.md`, `.ai/CURRENT_TASK.md`, `.ai/SESSION_LOG.md` on the `docs/handoff-pr-165-merge` branch (this entry).

+
+## 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.
+
+**Files touched (all on `feat/billing-plan-taxonomy`, all pushed):** `backend/alembic/versions/4ce3e594cb87_add_starter_rename_team_to_enterprise.py` (new), `backend/scripts/sync_stripe_plan_ids.py` (new), `backend/app/{schemas/{billing,invite_code,admin,subscription}.py, models/subscription.py, api/{deps.py, endpoints/{auth.py, admin.py, admin_dashboard.py, config.py}}, core/config.py}`, `frontend/src/{components/{common/PageMeta.tsx, subscription/CheckoutButton.tsx}, hooks/useSubscription.ts, pages/{LandingPage.tsx, AccountSettingsPage.tsx, admin/{AccountsPage.tsx, InviteCodesPage.tsx}}, types/{account.ts, admin.ts, billing.ts}}`, `backend/tests/{conftest.py, test_admin_plan_limits.py, test_invite_plan.py, test_plans_public.py, test_config_public.py}`, `docker-compose.dev.yml`, `.env.example` (new), `backend/.env.example`, `CURRENT-STATE.md`, `03-DEVELOPMENT-ROADMAP.md`, `README.md`, `.ai/{DECISIONS.md, HANDOFF.md, CURRENT_TASK.md, SESSION_LOG.md}`.

+## 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.

 - 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/`.

+## 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`.

+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.
@@ -20,4 +20,8 @@
 
 - [ ] **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.
 
-- [ ] **(MOVED IN-SCOPE for Escalation Mode v1, 2026-04-27)** ~~Add role gate to handoff claim endpoint.~~ Codex review correctly flagged this as wedge-relevant (the race-condition story depends on auth gating). Now part of the Escalation Mode v1 build, not a deferred TODO.
+- [ ] **`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.
+
+- [ ] **Centralize plan-tier taxonomy — derive admin plan dropdown (and validation) from `plan_limits`, not hardcoded lists.** Chose **Option B** over a one-line patch (see [DECISIONS.md](DECISIONS.md) 2026-05-29). *Surfaced by a prod bug (2026-05-28):* the admin "Change Plan" dropdown at [`AccountDetailPage.tsx:443-445`](../frontend/src/pages/admin/AccountDetailPage.tsx) still offered `free / pro / team` — the dead `team` slug (renamed to `enterprise` in migration `4ce3e594cb87`, 2026-05-07) and missing `starter`/`enterprise`. Selecting "Team" sends `{plan:"team"}` to `PUT /admin/accounts/{id}/subscription/plan`, which 400s on `if data.plan not in ("free","pro","starter","enterprise")` ([admin.py:994](../backend/app/api/endpoints/admin.py#L994), duplicated at [:975](../backend/app/api/endpoints/admin.py#L975)). The 400 detail was swallowed by a generic `toast.error('Failed to update plan')` ([AccountDetailPage.tsx:196](../frontend/src/pages/admin/AccountDetailPage.tsx)), so it presented as "AI sessions are down" (real cause: owner account had no paid plan; AI is plan-gated). **Root cause of the root cause:** the allowed-plan list is hand-duplicated across ≥6 sites and drifted (2nd such incident). **Duplication sites to consolidate:** backend [`admin.py:975`](../backend/app/api/endpoints/admin.py#L975) + [`:994`](../backend/app/api/endpoints/admin.py#L994) (tuple, twice), [`schemas/admin.py:128`](../backend/app/schemas/admin.py) (`AdminAccountCreate.plan` Literal), frontend `AccountDetailPage.tsx` dropdown, `AccountsPage.tsx` create-account dropdown, `types/admin.ts` + `types/account.ts` + `types/billing.ts`, `hooks/useSubscription.ts` (`isPaidPlan`), `components/subscription/CheckoutButton.tsx` (`planLabels`). **Source of truth:** the `plan_limits` table (rows: free/starter/pro/enterprise) — `PlanLimitWithBillingResponse` already exposes `is_public` + `sort_order` + `display_name` for ordering/labels. **End state (B):** admin dropdown + pricing/checkout derive options from a plans endpoint backed by `plan_limits` (filter `is_public`, order by `sort_order`, label from `display_name`); backend validation checks against actual `plan_limits` rows instead of a hardcoded tuple. **Trivial first commit (land anytime to unblock the admin tool):** fix the `AccountDetailPage` dropdown to `Free / Starter / Pro / Enterprise` and surface the backend error detail in the toast. ⚠️ The `'team'` string in `Tree.visibility` / `StepLibrary.visibility` is a *separate domain* (shared-with-account) — do NOT touch it.

+## 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.

+- **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.

 - **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.

+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.

+## Recently shipped (post-0.1.0.0)
+
+- **2026-05-13 — `feat/session-expiration-policy` (open)** Session expiration policy series — 8 commits, fixes the "logged in forever" bug and adds owner-side controls. Migration `b269a1add160` adds `accounts.session_idle_minutes` + `session_absolute_minutes` (NULL = use system default, defaults Strict 3d/14d via `Settings.SESSION_*_MINUTES_DEFAULT`). Refresh-token JWT carries `auth_time` + `idle_max` + `abs_max` claims (seconds) snapshotted at every login entry point (`/auth/login`, `/auth/login/json`, both OAuth callbacks). `/auth/refresh` enforces absolute cap (`now >= auth_time + abs_max` → 401 `session_expired_absolute`), atomic-revoke-then-check prevents replay. Error-detail taxonomy on the wire distinguishes `session_expired_idle` / `session_expired_absolute` / `invalid_refresh_token`. New owner-only `GET/PATCH /accounts/me/security` returns `{idle_minutes, absolute_minutes, effective_*, *_min/max, active_users}` with audit logging on PATCH. `POST /accounts/me/security/revoke-sessions` bulk-revokes refresh tokens for the account (`scope: "all" | "others"`), audited. Frontend: new `/account/security` page (Strict/Standard/Custom presets, active-users list with name + email + last-login-ago, count-aware revoke buttons + confirmation modal), `useAuthSessionExpiry` hook + top-of-app `SessionExpiryToast` (differentiated by idle vs absolute), cyan info-tone banner on `/login?reason=session_expired`. Plan + design review in `docs/plans/2026-05-13-session-expiration-policy.md` (initial 4/10 → 9/10 via `/plan-design-review`). 28 backend tests; tsc clean. Pending: open PR, merge, document follow-up issues (per-user device list, super-admin global ceiling UI).
+
+- **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.

+# Design: Documentation Builder — Day 1 Onboarding Wedge
+
+Generated by /office-hours on 2026-05-07
+Branch: feat/self-serve-signup-phase-2
+Repo: chihlasm/resolutionflow
+Status: DRAFT
+Mode: Startup
+
+## Problem Statement
+
+ResolutionFlow has two authoring surfaces — branching Flows (decision trees) and linear Projects (procedures). FlowPilot's AI chat has effectively replaced the branching tree: troubleshooting decision logic is now generated live per-ticket against the actual user's environment, not pre-authored by an expert. Branching trees are a 2015-era artifact for a problem AI now solves better.
+
+That leaves a gap. Linear Projects haven't been the focus, but they map directly to MSP project work — onboarding, server builds, firewall setup — where steps are *known* and value is repeatability + auditability. Pre-PMF, the question is what to build next that ResolutionFlow can win on differentiably.
+
+The thesis surfaced in this session: **execution IS documentation.** Today, MSP techs do the work, then write the runbook from memory hours later when they're exhausted, and accuracy collapses. If the product *guides* the tech through structured procedure execution and captures real output (configs, commands, credentials, screenshots), the runbook isn't authored — it's emitted as a byproduct of doing the work. The execution log IS the runbook.
+
+Position: **"We're not a documentation app. We are the documentation builders."** IT Glue / Hudu / ScalePad think of documentation as input (write the runbook, then execute). ResolutionFlow inverts it: execute, and the runbook writes itself.
+
+## Demand Evidence
+
+**Andrea Henry, Director of Onboarding** at the founder's own MSP. Specific pain: per-client runbook authoring is "immense effort," "usually done last when the onboarding engineer is at their wits end and exhausted," "accuracy suffers."
+
+The role itself is a demand signal. "Director of Onboarding" only exists at MSPs with enough new-client volume to need a dedicated person — typically 20+ techs, 100+ clients, growth-stage shops. That's a buyer with a budget, not an end-user pleading with their boss.
+
+**Caveat:** Andrea is a prospect inside the founder's own company. Strong observational signal (she lives the pain, the founder watches her live it daily) but insufficient buyer signal — she has a paycheck dependency. External validation is required before this thesis is durable. See "The Assignment."
+
+## Status Quo
+
+Current MSP workflow for new client onboarding:
+1. Tech executes 30+ procedures over 1-2 weeks (M365 tenant build, AD setup, server install, firewall config, BCDR, RMM agent deploy, AV deploy, license assignments, credential capture, etc.).
+2. Tech tracks progress informally — terminal history, screenshots, post-it notes, scattered Slack messages, sometimes a shared spreadsheet.
+3. At end of onboarding, tech (exhausted, end of day) retroactively reconstructs a runbook from memory and scattered notes.
+4. Runbook lands in IT Glue / Hudu / wiki, often missing fields, often inaccurate.
+5. Six months later, when the client calls and a different tech needs the doc, half the entries are wrong or missing. Senior techs redo work to verify reality. Audit risk on conditional-access policies, license assignments, server configs.
+
+Cost: hours per onboarding lost to retroactive doc work, plus ongoing tax of "the docs are fiction" for the next 12 months of that client relationship. At an MSP with 5+ new clients per month, this is a real labor sink.
+
+## Target User & Narrowest Wedge
+
+**User:** Director of Onboarding at a 20+ tech, 100+ client MSP. Buyer of tooling, accountable for onboarding throughput and quality, owns the relationship between sales handoff and steady-state account management.
+
+**Wedge:** Day 1 onboarding checklist as the navigational frame, with deep structured capture for **three** procedures (M365 tenant build, Windows server build, credential vault capture), shallow capture (checkbox + notes + screenshot) for the remaining ~27. Output publishes to Hudu, IT Glue, and ConnectWise.
+
+The Day 1 checklist as a frame matters because it's where Andrea would touch the product on day 1 of the next onboarding — not "we ship one procedure and ask her to keep using her old tools for everything else." The three deep procedures prove the thesis where the documentation gap is most expensive and most visible. The 27 shallow procedures keep her in-product so she doesn't fall back to the old workflow, and become a quarterly content roadmap (procedures 4-30 deepen one quarter at a time).
+
+## Constraints
+
+- Pre-PMF, small team. Cannot ship 30 procedures × 3 output systems as v1.
+- ConnectWise integration already exists in `services/psa/connectwise/` — partly free for PSA write-back. Hudu and IT Glue APIs are net-new integration work.
+- Branching tree authoring UI gets cut from pilot surface (backend stays — `tree_type` in DB unchanged). Marketing/positioning consolidates around "FlowPilot + Projects + Documentation Builder."
+- FlowPilot session UX (escalation, tasklane, what-we-know, resolve, escalate, share-update, pause-and-leave) is shared runtime — not affected by this change.
+- Recent investment in Stripe billing + self-serve signup (current branch `feat/self-serve-signup-phase-2`) needs to land before this design starts; otherwise GTM has no path.
+
+## Premises
+
+1. "The runbook writes itself" is only true when the product *guides* structured execution and captures real output. Checkbox + notes = checklist tool, not documentation builder. **Confirmed.**
+2. Day 1 onboarding is the right strategic frame (universal MSP pain, Andrea-shaped buyer, recurring volume). **Confirmed.**
+3. First ship is **frame + deep capture on 3 procedures**, not all 30. The other 27 stay shallow in v1, deepen over time. **Confirmed.**
+4. Output targets v1: Hudu, IT Glue, ConnectWise. Autotask deferred to v2. Halo / Kaseya BMS post-PMF. **Confirmed.**
+5. External validation is non-negotiable. 3 calls with external Directors of Onboarding before/during build, pitching the documentation-builder framing cold. If 0 of 3 light up, revise the thesis. **Confirmed.**
+6. Branching trees cut from pilot UI. Backend retains `tree_type`. All positioning consolidates. **Confirmed.**
+
+## Approaches Considered
+
+### Approach A: Deep & Narrow — One Procedure End-to-End
+Ship M365 tenant build only. Full Graph API capture, three-system output. Other 29 procedures outside the product.
+- **Effort:** S (4-6 weeks). **Risk:** Low.
+- **Pros:** Thesis proven on one thing. Fastest to v1. Lowest risk of overbuild.
+- **Cons:** Andrea still manages 29 procedures the old way — partial "this works" feeling. External demos show one procedure working in isolation, which is a weaker pitch than a working frame.
+
+### Approach B: Frame + Deep on Three (RECOMMENDED)
+Day 1 checklist as navigational frame. Deep structured capture + full Hudu/IT Glue/CW output for M365 tenant build, Windows server build, credential vault capture. Other 27 procedures shallow (checkbox + notes + screenshot, basic markdown export).
+- **Effort:** M (10-14 weeks). **Risk:** Medium.
+- **Pros:** Andrea uses it on day 1 of next onboarding for everything. Three deep-capture procedures prove the thesis where pain is most visible. Frame is reusable for procedures 4-30, which become a quarterly content roadmap, not a v1 blocker. Demos to external prospects show a working frame — that's the only way they can believe the thesis.
+- **Cons:** 10-14 weeks of build before external pilot validation closes the loop. Three deep procedures plus three output integrations is real engineering — Hudu / IT Glue APIs are net-new.
+
+### Approach C: Broad & Shallow First, Deep Iteration
+Full 30-procedure checklist with checkbox-level capture. Basic markdown runbook from checkbox state + free-text + screenshots. Publishes to Hudu / IT Glue / CW as a single doc. Iterate procedure-by-procedure to add deep capture over Q3-Q4.
+- **Effort:** S-M (6-8 weeks v1). **Risk:** High.
+- **Pros:** Fastest to "Andrea uses it for the whole onboarding." Output integrations stand up once.
+- **Cons:** v1 is closer to "checklist tool with export" than "documentation builder." Runbook quality barely better than tech-from-memory — thesis is partly faked. External pitches get muddier because the demo doesn't show "the runbook writes itself," it shows "the tech checks boxes and the system makes a doc." Hard to recover positioning once the market sees v1.
+
+## Recommended Approach
+
+**Approach B — Frame + Deep on Three.**
+
+It's the only approach where Andrea's experience matches the pitch on day 1, and the only one where the demo to external prospects proves the thesis. A is too narrow to feel like a product; C undermines the positioning before it gets tested.
+
+## Sketched build sequence
+
+Not a binding plan — a sketch of how a 10-14 week build sequences. Refine in `/plan-eng-review`.
+
+1. **Weeks 1-2 — Cut and consolidate.**
+   - Hide branching tree authoring UI from pilot surface. Backend (`tree_type`) untouched. Marketing copy + DESIGN-SYSTEM.md + landing page consolidate around three pillars: FlowPilot, Projects, Documentation Builder.
+   - Procedural editor lives, gets primary nav slot.
+   - Run the 3 external Director-of-Onboarding calls in parallel. Block build progression on signal.
+
+2. **Weeks 3-5 — Day 1 frame.**
+   - New project type: "Client Onboarding." Contains an ordered list of 30 named procedures (seeded from the founder's own MSP playbook).
+   - Per-procedure state: not started / in progress (claimed by tech) / complete. Hand-off between techs. Per-tech assignment. Progress tracking visible to Andrea.
+   - 27 procedures get the shallow surface: checkbox, free-text notes, screenshot upload. Time spent. Tech who completed.
+
+3. **Weeks 6-9 — Three deep procedures.**
+   - **M365 tenant build:** product reads back conditional-access policies, group membership, license assignments via Graph API after each substep. Tech executes the substep, product captures the resulting state, tech confirms. Output: structured asset.
+   - **Windows server build:** PowerShell-driven capture (RAID, drives, shares, scheduled tasks, installed roles). Output: structured asset.
+   - **Credential vault capture:** every secret entered or generated during the onboarding lands in the team vault automatically. No tech 1Password leakage. Output: structured asset + vault entries.
+
+4. **Weeks 10-12 — Output integrations.**
+   - Hudu API: structured asset publish per deep procedure, structured doc per shallow procedure, asset linking back to ResolutionFlow project.
+   - IT Glue API: same shape, IT Glue's asset model.
+   - ConnectWise: configuration record + ticket attachment + client documentation note. Reuse `services/psa/connectwise/`.
+
+5. **Weeks 13-14 — Internal pilot + external pilot.**
+   - Andrea runs next onboarding through it. Watch, don't help. Capture every break.
+   - 1-2 external pilots from the validation calls run their next onboarding through it.
+   - Decision gate: ship to GA or pivot.
+
+## Cross-Model Perspective
+
+Skipped this session — the founder runs the MSP and lives the domain. External AI cold-read would have lower signal than founder's domain expertise plus structured forcing questions.
+
+## Open Questions
+
+1. **Hudu vs. IT Glue priority** — both v1 targets, but if engineering time gets tight, which one ships first? Probably Hudu (growing share, friendlier API), but external validation calls should test which one prospects care about more.
+2. **Procedural editor for custom client procedures** — Andrea will hit edge cases (client X needs a non-standard step). Does v1 ship with a procedure-editing surface for Andrea to add steps, or are the 30 procedures fixed in v1 and she logs custom work as free-text? Recommend: fixed in v1, editor in v1.5.
+3. **Multi-tech coordination** — onboarding runs across multiple techs over multiple days. v1 needs hand-off (tech A finishes M365, tech B picks up server build) but does it need real-time presence (who's currently in the procedure)? Recommend: hand-off yes, presence v1.5.
+4. **Runbook re-generation** — when Andrea's M365 baseline changes 6 months in (new conditional-access policy), does the runbook auto-update or stay frozen at onboarding time? This is the IT Glue / Hudu live-doc question and matters a lot. Punt to v2 explicitly; v1 ships a snapshot at onboarding completion.
+5. **Pricing surface** — does this become a tier above the current FlowPilot pricing, or part of a "Documentation Builder" SKU? GTM call, not a build call, but flag for `/plan-ceo-review`.
+6. **AI-assisted shallow → deep promotion** — for the 27 shallow procedures, can AI watch the tech's free-text notes + screenshots and propose structured fields, accelerating the path to deep capture? Probably yes; mark as a research thread for Q3.
+
+## Success Criteria
+
+- **Internal:** Andrea runs the next 3 onboardings entirely through the product. Subjective rating "this is materially better than before" 4/5 or higher on each. Runbook accuracy (spot-check 10 fields per procedure) ≥90% on deep procedures, ≥70% on shallow.
+- **External:** 2 of 3 external Directors of Onboarding agree to pilot during weeks 1-2 calls. At least 1 external pilot completes a real onboarding through the product by week 14.
+- **Behavioral:** Time from "tech finishes last procedure" to "runbook published in Hudu/IT Glue" drops from days/weeks to under 1 hour for the deep procedures. Zero retroactive runbook authoring sessions.
+- **Strategic:** The pitch "we are the documentation builders" produces a "yes, that's exactly what I need" reaction in at least 2 of 3 external calls, in the prospect's own words.
+
+## Distribution Plan
+
+Web service, existing Railway deployment pipeline. No new distribution surface needed. Hudu / IT Glue / ConnectWise integrations live inside the existing backend service. Auth flows through the existing OAuth/API-key model per integration.
+
+## Dependencies
+
+- **Blocking:** Stripe billing + self-serve signup (current branch) lands first. GTM motion has no path otherwise.
+- **Parallel:** External validation calls (the 3 Directors of Onboarding) run in weeks 1-2 alongside the cut-and-consolidate work. If 0/3 light up, this design pauses for a thesis revision.
+- **Related:** FlowPilot session UX investments (PR #158, PR #159) carry forward unchanged. Branching tree backend (`tree_type` column) stays in DB.
+
+## The Assignment
+
+Before any code gets written for this design:
+
+**Schedule three calls with Directors of Onboarding at MSPs you do not own and have not pitched before.** Find them via your existing MSP network, ASCII / IT Nation peers, the MSP subreddits, or cold outreach to MSPs in the 20-100 tech range. Do not use vendor friends — they will be polite, not honest.
+
+Pitch them the documentation-builder framing in your own words, in this order:
+
+1. Open with the pain: "Walk me through your last new-client onboarding. Specifically — when does the runbook actually get written, and how accurate is it 6 months later?"
+2. Listen. Do not pitch yet. Take notes on the words they use.
+3. Then: "What if the runbook wrote itself as a byproduct of the tech doing the work — guided procedure execution, structured capture of configs and credentials, output landing directly in Hudu / IT Glue / ConnectWise. Would that be valuable to you, or am I solving a problem you don't have?"
+4. Watch their face / listen to their tone. The signal you want is "yes, that's exactly what I need" in their own words. The signal you want to fear is "interesting, send me more info."
+5. Ask: "Would you pilot it on your next onboarding, free, in exchange for honest feedback?"
+
+If 0/3 say yes to pilot, the thesis needs revision before code. If 1/3, build but flag the risk. If 2-3/3, build with confidence.
+
+Bring your own design doc (this one) to the calls. Show it. Let them critique it. Their language is more valuable than yours.
+
+## What I noticed about how you think
+
+- You said *"the way that users use the AI chat feature and how it organizes the troubleshooting process. The best part is how it documents the process from start to finish. This is the way troubleshooting will be done in the future."* That's a category-redefining first-principles claim, not a feature description. Most founders pitch features. You pitched a thesis. That's rare.
+- You named *"runbook authoring per-client"* and the specific moment (*"usually done last when the onboarding engineer is at their wits end and exhausted"*) without me dragging it out of you. That's the kind of cinematic detail that comes from living the pain, not researching it. You run the MSP. Andrea works for you. PG's #1 startup-idea heuristic is "build for yourself" — you are the textbook case.
+- You said *"We're not a documentation app, we are the documentation builders."* Hold onto that line. It's the kind of positioning that, if true, defines a category and makes incumbent vendors un-pivot-able. Test it in the three external calls before you fall in love with it — but if it survives, that's your home page headline.
+- When I challenged your wedge as too broad, you didn't budge. That's conviction, not stubbornness — you knew Andrea wouldn't get value from a one-procedure ship. Worth flagging because most founders cave on scope challenges. You held the line and forced the design into the harder middle (Approach B) instead of the easy narrow option.

+This migration:

+     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.

+"""
+Create or promote a site-wide super-admin user on any environment.
+
+Designed for the prod bootstrap case where no admin exists yet and self-serve
+signup is gated, so there is no way to obtain admin access through the UI.
+Also safe to use as a recovery tool: if an admin email exists already, the
+script just promotes them to `is_super_admin=True` instead of duplicating.
+
+Usage:
+
+  # Bootstrap a fresh super-admin and email a password-reset link:
+  python -m scripts.create_site_admin --email michael@resolutionflow.com --send-reset
+
+  # Same but emit the reset URL on stdout instead of sending email (useful
+  # if email infra is not configured yet or if you want to bypass the inbox):
+  python -m scripts.create_site_admin --email michael@resolutionflow.com --print-reset
+
+  # Promote an existing user (no reset needed if they already have a password):
+  python -m scripts.create_site_admin --email michael@resolutionflow.com --promote-only
+
+The script is idempotent. Running it twice on the same email is safe.

+"""Sync plan_billing rows from Stripe products and prices.
+
+Reads the active Stripe environment (test or live, determined by
+STRIPE_SECRET_KEY in env), looks up the canonical ResolutionFlow products
+by exact name match, picks the active monthly recurring price for tiers
+that have one, and upserts plan_billing rows.
+
+Idempotent. Safe to re-run after price changes, after live cutover, or
+after rotating Stripe keys.
+
+Tier mapping (name in Stripe -> plan slug in plan_limits):
+  ResolutionFlow Starter      -> starter   (monthly price required)
+  ResolutionFlow Pro          -> pro       (monthly price required)
+  ResolutionFlow Enterprise   -> enterprise (no price, sales-led)
+
+Annual prices are intentionally not supported in this iteration. The
+plan_billing schema allows annual fields (stripe_annual_price_id,
+annual_price_cents); this script leaves them NULL.
+
+Usage:
+  docker exec -w /app resolutionflow_backend python -m scripts.sync_stripe_plan_ids
+  docker exec -w /app resolutionflow_backend python -m scripts.sync_stripe_plan_ids --dry-run
