-**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:** Self-serve signup Phase 2 — PR #162 is open on `feat/self-serve-signup-phase-2`. Current focus is resolving its failing Gitea checks. Phase O manual ops (Stripe live setup, internal validation, flag flip) remain pending after review/merge. 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.

-**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).
+- **2026-05-06 — `feat/self-serve-signup-phase-2`** Phase 2 frontend cutover code (Tasks 27–44 of the plan, 18 commits). 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. Phase O (Stripe live setup, internal validation, flag flip) is operational and pending. Single alembic head `c6cbfc534fad` (no new migrations).
+- **2026-05-02 — PR #159** In-product User Guides rewrite. Merged into `main`. Replaced 15 feature-dump guides with 43 problem-oriented Diátaxis how-tos grouped under 10 categories. Dropped Maintenance Flows / AI Assistant / Flow Assist Sparkles (UI no longer exists). Renamed Step Library → Solutions Library. Authored 14 net-new how-tos for FlowPilot-era surfaces (tasklane keyboard flow, what-we-know, resolve, escalate, record-fix-outcome, post-docs-to-ticket, share-update, pause-and-leave, build-script-from-scratch, open-suggested-flow, pin-a-flow, invite-teammate, etc.). Schema additions: `category`, optional `relatedSlugs`; hub renders category sections; detail page renders related-guides footer. Fixed rendering bug where `**bold**` in `step.tip` rendered literally. Killed misleading "N sections" subtitle on guide cards. Browser-verified against engineer + owner login (sidebar labels, account sub-pages, pilot-screen header buttons, Tasks panel, integration form). Two unverified items intentionally deferred: change-teammate-role (requires non-owner test member to inspect role-change control) and detailed Resolve / Escalate modal contents (Resolve gated by 6 pending tasks in test data). tsc and Vite build clean.
+- **2026-05-01 — PR #158** Session-screen UX impeccable pass + tasklane keyboard flow. Merged into `main` as `5e10005`.
+  - **Impeccable pass** (5 sub-passes — distill / quieter / layout / typeset / polish): score 24/40 → 33/40. Removed the duplicate "Suggested checks" chip strip; added an inline `Next steps · N pending in Tasks` cue above the latest action-bearing AI bubble; consolidated the desktop session header to Resolve + Escalate + ⋯ kebab (Context / New Ticket / Update Ticket / Pause now under the kebab, mobile kebab gained Context + New Ticket parity); centered the messages column to `max-w-3xl` to match the composer; bubbles dropped to `rounded-xl`. Decoration sweep: dropped 3px side stripes (TaskLane done states, all 6 ProposalBanner modes, WhatWeKnowItem rows), gradient backgrounds (WhatWeKnow + every banner), accent borderTop on TaskLane header, backdrop-blur on handoff overlay, animate-pulse-amber ring in VerifyingBanner, bordered avatar boxes in banners. Type sweep: 14 distinct sizes → 5-step scale (10/11/12/13/14px). Icon disambiguation: `MessageCircleQuestion` split into `Pencil` (Answer CTA) + `HelpCircle` (per-check explainer). Dead `font-sans` audit (12 sites) and double `text-xs` cleanups.
+  - **TaskLane keyboard-first flow** (real feature): Enter submits + auto-advances to next pending task, Shift+Enter newline, Esc cancels, focus jumps to Send Responses after the last submission. Mouse path also auto-advances. Subtle hint row teaches the shortcut.
+  - **Banner ↔ script panel linked**: collapsing or dismissing the ProposalBanner now also hides the InlineNoTemplateDialog / TemplateMatchPanel; recording any outcome closes both surfaces.
+  - **WhatWeKnow collapsible**: per-session preference in `sessionStorage` (`rf-whatweknow-collapsed:{sessionId}`); auto-collapses on first render at ≥5 facts.
+  - **Side fix**: `ParameterizationPreview.tokenize()` word-boundary guard prevents over-eager highlighting of short values like `"D"` (no longer lights up every capital D in `Get-ADUser`).
+  - Validation: tsc clean, ESLint clean, Vite build clean. Type-check + lint passed at every commit boundary.
+- **2026-05-01 — PR #156** Suggested-fix `applied_pending` non-terminal outcome. Merged into `main` as `3ba4532`. Adds:
+  - Schema/API: `FixStatus="applied_pending"`, `pending_reason` Text column, migration `c0f3a4b7e91d`. `PATCH /suggested-fixes/{id}/outcome` accepts pending, requires notes, stamps `applied_at` only.
+  - UI: `PendingBanner` (info-tone, worked / didn't / update reason / dismiss). "Waiting to verify…" overflow option in `VerifyingBanner`. Nudge "Still checking" records pending with a reason. Page-level Resolve auto-patches pending → success before resolution flow; page-level Escalate intercepts pending the same way verifying/partial does.
+  - Generators: `resolution_note_generator` and `escalation_package_generator` system prompts handle the new status without real-looking examples.
+  - Tests: 4 new in `test_fix_outcome_endpoint.py` (21/21 suite green); prompt anti-parrot guardrail green; tsc + Vite build clean.
+  - QA report: `.gstack/qa-reports/qa-report-pending-verification-2026-04-30.md` (5/7 scripted checks PASS with concrete evidence; 2 entry-path checks deferred — same handlers verified via tested transitions).

+## 2026-05-07 — 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.
-
-**Just-merged:** PR #155 (Escalation Mode wedge) merged into main as `ac42f97`.
+**Active task:** PR #162 (`feat/self-serve-signup-phase-2`) is open in Gitea. Current session is resolving its failing checks.
 
 ## Where this session ended
 
-PR #156 was reviewed for missed bugs and three fixes were applied:
+PR #162 originally failed quickly in Gitea CI. Public Gitea status metadata was available, but job logs redirected to login and no `GITEA_TOKEN` was present. The branch was pushed over SSH.
 
-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.
+Fixed environment drift first:
 
-**Validation on PR #156:**
+- Standardized backend native/dev/CI Python on 3.12.13 to match Docker.
+- Added `.python-version`.
+- Rebuilt `backend/venv` from pyenv Python 3.12.13 and verified native `pytest --version` / `alembic --version` with explicit local env.
+- Updated Gitea CI backend/e2e Python setup to 3.12.
 
-- `docker exec resolutionflow_backend pytest --override-ini="addopts=" tests/test_prompt_anti_parrot.py -q` ✅ 2/2 pass.
-- `docker exec resolutionflow_backend pytest --override-ini="addopts=" tests/test_fix_outcome_endpoint.py -q` ✅ 21/21 pass.
-- `docker exec -w /app resolutionflow_frontend npx tsc -b` ✅ exit 0.
-- `docker exec -w /app resolutionflow_frontend npm run build` ✅ exit 0; only existing Vite large-chunk warning.
-- `git diff --check` ✅ clean.
-- Previous session also verified `alembic upgrade heads` applied migration `c0f3a4b7e91d` cleanly.
+Fixed Gitea runner assumptions next:
 
-## Resume point — DO THIS NEXT
+- Added `actions/setup-node@v4` with Node 20 to Gitea frontend and e2e jobs.
+- Pushed `fix(ci): set up node in gitea workflow`.
 
-**Browser QA on PR #156** (see CURRENT_TASK.md "Resume point" for the checklist). Include the new review-fix paths: PendingBanner Dismiss, page-level Resolve from pending, and Escalate from pending. Then commit local fixes, push, and merge when QA is green.
+Local frontend validation then exposed real lint failures in Phase 2 React code under the current lint stack. The current WIP fixes:
 
-## Key files for PR #156
+- `react-refresh/only-export-components` for exported pure helpers used by tests/shared invite OAuth code.
+- `react-hooks/set-state-in-effect` warnings where local state intentionally mirrors route/config/cache state.
+- `react-hooks/purity` warnings from `Date.now()` during render.
+- Redundant loading-state write in pricing page.
 
-- `backend/app/models/session_suggested_fix.py` — CHECK constraint extended; `pending_reason` Text column.
-- `backend/app/schemas/session_suggested_fix.py` — `applied_pending` added to both `FixStatus` and `FixOutcome` literals; `pending_reason` on response model; updated docstring on `SessionSuggestedFixOutcomeRequest`.
-- `backend/alembic/versions/71efd2102f49_add_pending_status_to_suggested_fixes.py` — new migration (rev `c0f3a4b7e91d`, down `71efd2102f49`).
-- `backend/app/api/endpoints/session_suggested_fixes.py` — `patch_outcome` accepts pending, requires notes, stamps applied_at only.
-- `backend/app/services/{resolution_note,escalation_package}_generator.py` — system-prompt handling for the new status; `pending_reason` line in input bundle; real-looking examples removed.
-- `backend/tests/test_fix_outcome_endpoint.py` — 4 new tests.
-- `frontend/src/api/sessionSuggestedFixes.ts` — types updated; `pending_reason` on `SessionSuggestedFix`.
-- `frontend/src/components/pilot/ProposalBanner.tsx` — `'pending'` `BannerMode`; `PendingBanner` component + Dismiss; "Waiting to verify…" overflow option; nudge "Still checking" wired to record pending.
-- `frontend/src/components/pilot/EscalateInterceptDialog.tsx` — copy generalized for pending/partial/verifying outcome capture.
-- `frontend/src/pages/AssistantChatPage.tsx` — banner-mode derivation maps `applied_pending → 'pending'`; Resolve/Escalate paths now handle pending.
+Validation after those frontend changes:
 
-## Watch-outs
+- `docker exec -w /app resolutionflow_frontend npm run lint` passed.
+- `docker exec -w /app resolutionflow_frontend npm run test:coverage` passed (`198` tests).
+- `docker exec -w /app -e NODE_OPTIONS=--max-old-space-size=4096 resolutionflow_frontend npm run build` passed.
 
-- 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.
+Known local noise:
+
+- React `act(...)` warnings appeared in existing tests during coverage but did not fail the suite.
+- Vite emitted large chunk warnings during build.
+- Unrelated dirty/untracked files remain and should not be staged unless explicitly requested: `docker-compose.dev.yml`, `.env.example`, `abc-feat-self-serve-signup-phase-2-design-20260507-112020.md`, `core.*`, `docs/architecture/`, `docs/tutorials/`.
+
+## Resume point
+
+1. Commit the frontend lint fixes and `.ai/` handoff updates with the required Codex trailer.
+2. Push `feat/self-serve-signup-phase-2`.
+3. Poll Gitea PR #162 statuses for the new head SHA:
+   `curl -fsSL https://gitea.resolutionflow.com/api/v1/repos/chihlasm/resolutionflow/statuses/<sha> | python -m json.tool`
+4. If statuses are still pending, report that local frontend CI is green and Gitea runner work is queued/running. If a check fails, public statuses may show only the context/description; logs require authenticated Gitea access.
+
+## Carry-forward
+
+- Phase O manual ops remain pending after PR review/merge: Stripe live setup, internal validation, feature-flag flip.
+- Backend env: `SALES_LEAD_RECIPIENT_EMAIL`.
+- Frontend env: `VITE_SELF_SERVE_ENABLED`, `VITE_GOOGLE_CLIENT_ID`, `VITE_MS_CLIENT_ID`, `VITE_OAUTH_REDIRECT_BASE`, `VITE_CALENDLY_URL`.
+- Single alembic head remains `c6cbfc534fad`; Phase 2 added no migrations.

+- 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.

+- 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.

+- 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.

+## 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`.

 - 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.

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/`.

+
+- 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.

 ## Backlog

+- [ ] **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.

 - [ ] **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.

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.

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

 ### Changed
+- **Assistant Chat session screen — UX overhaul** (#158, "impeccable" pass) — removed the duplicate "Suggested checks" chip strip in favor of the TaskLane as the single source of truth; added an inline `Next steps · N pending` cue above the latest action-bearing AI bubble; consolidated the session header to two visible primary actions (Resolve + Escalate) plus a kebab for Context / New Ticket / Update Ticket / Pause; centered the messages column to `max-w-3xl` to match the composer; unified chat-bubble radii to `rounded-xl`; dropped every banned decoration (3px side stripes, gradient surfaces, accent borderTop, backdrop blur, pulse rings, bordered avatar boxes) for a single decoration channel per surface; unified 14 distinct text sizes into a 5-step scale (10/11/12/13/14px); split the ambiguous `MessageCircleQuestion` icon into `Pencil` (write affordance for question Answer CTA) and `HelpCircle` (universal help icon for the per-check explainer); audited and dropped redundant `font-sans` classes across the screen.
+- **Suggested-fix banner ↔ script panel are now linked** (#158) — collapsing the ProposalBanner now also hides the InlineNoTemplateDialog / TemplateMatchPanel; dismissing the banner closes both surfaces. Recording any outcome on a fix (Dismiss, It worked, Didn't work, Mark partial, Waiting to verify) closes the script panel alongside the banner state transition.
 - **Edit Procedure page** — layout overhaul and color system refinements for better visual hierarchy
 - **Flows sidebar navigation** — collapsed to reduce visual noise; session recovery removed from library view
 - **Account settings page** — audit fixes for improved consistency and usability
@@ -52,6 +61,7 @@ All notable changes to ResolutionFlow are documented here.
 - **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.

+- **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.

+# Issue Cleanup Plan - 2026-05-01
+
+## Tracker Hygiene
+
+These are safe tracker updates before any feature work:
+
+1. Close Gitea #127 (`feat: show AI content scope indicator`) unless an always-visible badge is still desired.
+   - Current code already has IT/MSP scope copy in the assistant empty state.
+   - `ASSISTANT_SYSTEM_PROMPT` also has an off-domain redirect boundary.
+2. Rewrite Gitea #66 (`Tree Templates + Import/Export`) to the remaining scope only.
+   - `.rfflow` export/import is implemented in `tree_transfer.py` and exposed in the library UI.
+   - Remaining work: curated packs, authenticated one-click install from gallery, template versioning, marketplace/community path.
+3. Close or archive open PR #124 (`feat/cockpit-harness`).
+   - It is unmergeable against current `main` and overlaps newer `/pilot` work.
+4. Keep Gitea #58, #60, #128, #129, #130 open.
+   - They still describe real product gaps.
+
+## Recommended Order
+
+### 1. Low-Risk Maintenance
+
+- Status: started 2026-05-01.
+- Frontend lint is clean after removing stale disable comments and tightening hook dependencies.
+- Added `data-testid` selectors for e2e-critical session history and FlowPilot command-palette controls.
+- Added `AssistantChatPage` observability for unexpected `currentChatRef` guard mismatches so stale async discards are visible in the console.
+
+Why first: these reduce future regression cost and are small, well-bounded changes.
+
+### 2. Pilot UX Friction
+
+- Status: started 2026-05-01.
+- #130: Added diagnostic command help affordances in `TaskLane` action cards. Each active diagnostic card can explain what it checks, what to look for, and when to use it.
+- #128: Keep the existing responsive drawer behavior for now. `TaskLane` already uses a side panel on wide screens and a bottom drawer below the desktop breakpoint; do not add a top/side preference unless pilot feedback shows the current responsive layout is blocking workflow.
+- EscalationQueue mobile design stays deferred until a customer asks for it.
+
+Why second: this improves the current FlowPilot wedge without changing core data models.
+
+Validation run:
+
+- `docker exec -w /app resolutionflow_frontend npm run lint`
+- `docker exec -w /app resolutionflow_frontend npx tsc -b`
+- `docker exec -w /app resolutionflow_frontend npm run build`
+
+### 3. Workflow Quality Signals
+
+- #58: Add structured "step is wrong" flags separate from thumbs-up/down helpfulness.
+- Existing `StepFeedback` is not enough; it only records helpful/unhelpful and cannot capture incorrect/outdated/unclear/missing-info reasons.
+
+Why third: useful, but needs schema/API/UI/admin surfaces.
+
+### 4. Client Intelligence
+
+- #60: Recurring issue detection.
+- Start with a read-only banner using existing `sessions.client_name + tree_id` filters.
+- Add same-resolution detection only after confirming the available session outcome/node data is reliable enough.
+
+Why fourth: high value, but it touches session-start and close-out flows and needs careful false-positive handling.
+
+### 5. Documentation Structure
+
+- #129: Hierarchical guide navigation.
+- Current `/guides` route is a card grid plus detail pages with sections and breadcrumbs, but not a collapsible guide tree.
+
+Why fifth: valid UX request, but less urgent than pilot workflow gaps.
+
+## Gitea Actions Needed
+
+The current environment does not have a Gitea token configured, so API writes fail with `401 token is required`. Once authenticated:
+
+```bash
+curl -X PATCH \
+  https://gitea.resolutionflow.com/api/v1/repos/chihlasm/resolutionflow/issues/127 \
+  -H "Authorization: token $GITEA_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{"state":"closed"}'
+```
+
+For #66, prefer editing the title/body instead of closing it:
+
+- Title: `feat: curated template packs and one-click install`
+- Body: remove completed `.rfflow` export/import acceptance criteria and keep pack/install/versioning work.

+# Self-Serve Signup & Onboarding — Phase 2: Frontend + Cutover
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.
+>
+> **Granularity note:** Unlike Phase 1, this plan defines *contracts and acceptance criteria* — not every component detail. Implementers exercise judgment on internal structure (hooks vs. props, file splits, CSS organization) as long as the contracts hold and integration tests pass. Steps use checkbox (`- [ ]`) syntax for tracking; each task is one mergeable PR.
+
+**Goal:** Layer the user-facing self-serve flow on top of the Phase 1 backend foundation — pricing page, OAuth buttons + register redesign, welcome wizard, dashboard redesign with trial pill + next-step card + checklist, accept-invite page, sales contact form, billing portal — gated behind `SELF_SERVE_ENABLED` and `VITE_SELF_SERVE_ENABLED` until cutover.
+
+**Architecture:** Frontend reads billing state from a new `useBillingStore` Zustand store fed by `GET /billing/state`. New routes layer on the existing React Router v7 + lazyWithRetry pattern. Wizard state is server-persisted via `PATCH /users/me/onboarding-step`. Authenticated routes mount under existing `AppLayout`; public routes (pricing, contact-sales, accept-invite, verify-email) are top-level. Cutover is two flag flips: backend `SELF_SERVE_ENABLED=true`, frontend `VITE_SELF_SERVE_ENABLED=true`.
+
+**Tech Stack:** React 19 + Vite + TypeScript, Tailwind v4 (CSS-only config), Zustand (immer + zundo), React Router v7, Axios, Lucide. Backend additions: a few small endpoints (Phase 1 left them out) — see Phase I.
+
+**Spec reference:** `docs/superpowers/specs/2026-05-05-self-serve-signup-onboarding-design.md` (commit `bbb01ef`).
+**Phase 1 reference:** `docs/superpowers/plans/2026-05-06-self-serve-signup-phase-1-backend.md`.
+
+---
+
+## Phase Sequencing
+
+Each phase ends in a mergeable PR. Frontend gates everything behind `VITE_SELF_SERVE_ENABLED` so the new surfaces stay invisible to public users until Phase O cutover.
+
+| Phase | Tasks | Outcome |
+|---|---|---|
+| I | 27–31 | Backend endpoints Phase 1 deferred + `SELF_SERVE_ENABLED` flag + `/admin/plan-limits` extension |
+| J | 32–34 | Frontend billing foundation: `useBillingStore`, hooks, gating components — proven against Phase 1 backend |
+| K | 35–37 | Auth surfaces: register redesign with OAuth buttons, accept-invite page, email-verification surfaces |
+| L | 38–39 | Welcome wizard — 3 steps with persistence |
+| M | 40–41 | Dashboard redesign — trial pill, next-step card, checklist redesign |
+| N | 42–44 | Public surfaces: pricing page, contact-sales form, landing-page CTA, beta-signup 307 |
+| O | 45–47 | Cutover: Stripe live-mode setup, internal validation, feature-flag flip |
+
+---
+
+## Phase I — Backend endpoints + admin extension + feature flag
+
+### Task 27: BillingService.open_customer_portal + GET /billing/portal-session
+
+**Outcome:** Authed users can request a Stripe-hosted Customer Portal URL for card updates and cancellation.
+
+**Contract:**
+
+```
+GET /api/v1/billing/portal-session
+  → 200 { url: string }
+  → 503 when STRIPE_SECRET_KEY unset
+  → 400 when account has no stripe_customer_id (must complete checkout first)
+```
+
+`BillingService.open_customer_portal(account)` creates a `stripe.billing_portal.Session` with `return_url=$FRONTEND_URL/account/billing` and returns the session URL.
+
+**Acceptance criteria:**
+
+- [ ] Endpoint mounted at `/billing/portal-session` and is in the `_SUBSCRIPTION_GUARD_ALLOWLIST` and `_EMAIL_VERIFICATION_ALLOWLIST` (so it works for canceled / unverified-past-grace users who need to update billing).
+- [ ] Returns 400 with `{"error": "no_stripe_customer"}` when `account.stripe_customer_id is None`.
+- [ ] Stripe call mocked via `respx`; happy-path test asserts shape `{url: ...}`.
+
+**Integration test added:**
+
+- `test_billing_portal_returns_url_for_account_with_stripe_customer`
+
+**Commit:** `feat(billing): add BillingService.open_customer_portal + GET endpoint`
+
+---
+
+### Task 28: PATCH /users/me/onboarding-step
+
+**Outcome:** Welcome wizard can persist Step 1/2/3 state to the server.
+
+**Contract:**
+
+```
+PATCH /api/v1/users/me/onboarding-step
+  body: {
+    step: 1 | 2 | 3,
+    action: "complete" | "skip",
+    data?: {
+      // step 1
+      company_name?: string,
+      team_size_bucket?: "1-2"|"3-5"|"6-10"|"11-25"|"26+",
+      role_at_signup?: "owner"|"lead_tech"|"tech"|"other",
+      // step 2
+      primary_psa?: "connectwise"|"autotask"|"halopsa"|"none",
+      // step 3 has no data — invitations posted separately to /accounts/me/invites/bulk
+    },
+  }
+  → 200 { onboarding_step_completed: int, onboarding_dismissed: false }
+```
+
+Writes:
+- step=1 + action=complete → `accounts.name`, `accounts.team_size_bucket`, `users.role_at_signup`, `users.onboarding_step_completed=1`
+- step=1 + action=skip → `users.onboarding_step_completed=1` only (no field writes)
+- step=2 → `accounts.primary_psa` (only on complete) + `users.onboarding_step_completed=2`
+- step=3 → `users.onboarding_step_completed=3` (the actual invites POST is separate)
+
+Validates: `step` cannot decrease; `action="skip"` ignores the `data` payload.
+
+**Endpoint also exposes a sibling:** `POST /users/me/onboarding-dismiss-rest` → sets `users.onboarding_dismissed=TRUE`. Used by "Skip the rest" button.
+
+**Acceptance criteria:**
+
+- [ ] In `_EMAIL_VERIFICATION_ALLOWLIST` (so users can move through the wizard before verifying email).
+- [ ] In `_SUBSCRIPTION_GUARD_ALLOWLIST` (wizard runs during the trial; never gated).
+- [ ] Refusing to decrease `step` is enforced (a step=2 PATCH followed by step=1 returns 400).
+- [ ] Tests cover: complete with data writes fields; skip without data only advances step; idempotent re-PATCH of same step.
+
+**Integration tests added:**
+
+- `test_onboarding_step1_complete_writes_account_name_and_team_size_and_role`
+- `test_onboarding_step2_skip_advances_without_psa`
+- `test_onboarding_step_cannot_decrease`
+- `test_onboarding_dismiss_rest_sets_flag`
+
+**Commit:** `feat(onboarding): add PATCH /users/me/onboarding-step + dismiss-rest`
+
+---
+
+### Task 29: POST /sales-leads endpoint
+
+**Outcome:** Public Talk-to-sales form has somewhere to post.
+
+**Contract:**
+
+```
+POST /api/v1/sales-leads
+  body: {
+    email: string,
+    name: string,
+    company: string,
+    team_size?: string,
+    message?: string,
+    source: "pricing_page" | "register_footer" | "landing_page",
+    posthog_distinct_id?: string,
+  }
+  → 201 { id: uuid, status: "received" }
+```
+
+Public — no auth required. Rate-limit: max 5 submissions per IP per hour (use existing `core.rate_limit`).
+
+Side effects:
+1. Insert `sales_leads` row.
+2. Fire-and-forget `EmailService.send_sales_lead_notification` to `settings.SALES_LEAD_RECIPIENT_EMAIL` (new env var, default `sales@resolutionflow.com`).
+3. Emit PostHog server-side event `talk_to_sales_form_submitted` with `source` property.
+
+**Acceptance criteria:**
+
+- [ ] Anti-spam: rate-limited per IP.
+- [ ] Email send failure doesn't fail the request (logged warning).
+- [ ] Sales-lead recipient email is configurable; defaults to a placeholder until cutover.
+
+**Integration tests:**
+
+- `test_sales_lead_creates_row_and_sends_notification_email`
+- `test_sales_lead_rate_limited_after_5_per_hour`
+
+**Commit:** `feat(sales): add POST /sales-leads public endpoint`
+
+---
+
+### Task 30: Extend /admin/plan-limits to surface plan_billing fields
+
+**Outcome:** Super-admins can manage plan_billing (Stripe IDs, display names, prices, public/archived flags) via the same admin page they already use.
+
+**Contract change:**
+
+```
+GET /api/v1/admin/plan-limits → list[PlanLimitWithBillingResponse]
+
+PlanLimitWithBillingResponse extends PlanLimitResponse with:
+  display_name?: string
+  description?: string
+  monthly_price_cents?: int | null
+  annual_price_cents?: int | null
+  stripe_product_id?: string | null
+  stripe_monthly_price_id?: string | null
+  stripe_annual_price_id?: string | null
+  is_public?: bool
+  is_archived?: bool
+  sort_order?: int
+
+PUT /api/v1/admin/plan-limits accepts the same fields; updates plan_billing
+in the same transaction. If a plan_billing row doesn't exist for the plan,
+PUT creates it.
+```
+
+**Acceptance criteria:**
+
+- [ ] Single PUT round-trips both `plan_limits` and `plan_billing` in one transaction.
+- [ ] Cache invalidation: `app.state.billing_cache` flushed for all accounts on the affected plan.
+- [ ] No new admin page in v1 — existing `/admin/plan-limits` UI just gets new form fields.
+
+**Integration tests:**
+
+- `test_admin_plan_limits_get_includes_plan_billing_fields_when_present`
+- `test_admin_plan_limits_put_creates_plan_billing_row`
+- `test_admin_plan_limits_put_invalidates_billing_cache`
+
+**Commit:** `feat(admin): extend /admin/plan-limits to manage plan_billing fields`
+
+---
+
+### Task 31: Wire SELF_SERVE_ENABLED feature flag
+
+**Outcome:** A single flag controls whether the new public-facing self-serve flow is exposed.
+
+**Contract:**
+
+Backend:
+- `settings.SELF_SERVE_ENABLED: bool = False` (already added in Phase 1 Task 14).
+- New endpoint `GET /api/v1/config/public` (no auth) returns `{self_serve_enabled: bool, oauth_providers: ["google", "microsoft"] | []}` — frontend reads this once at load.
+
+Frontend:
+- `VITE_SELF_SERVE_ENABLED` env var (build-time bake-in per Lesson 60).
+- New `useAppConfig` hook: prefers backend `/config/public` response, falls back to `VITE_SELF_SERVE_ENABLED` for build-time gating.
+- Public routes (`/pricing`, `/contact-sales`, `/accept-invite`, OAuth callbacks) return 404 from the frontend router when `self_serve_enabled === false`.
+- Register page hides OAuth buttons + invite-code-removed copy when flag is off (preserves the existing invite-code-required register flow).
+
+**Acceptance criteria:**
+
+- [ ] Flag is OFF by default in all envs except where explicitly enabled.
+- [ ] When OFF: existing `/auth/register` invite-code flow still works exactly as today.
+- [ ] When ON: new flows are reachable; invite-code requirement is removed (the field still exists in the schema for backward-compat but the gate-check accepts NULL).
+
+**Integration tests:**
+
+- `test_get_config_public_returns_self_serve_flag`
+- `test_register_invite_code_required_when_self_serve_disabled` (regression)
+- `test_register_invite_code_optional_when_self_serve_enabled`
+
+**Commit:** `feat(config): add SELF_SERVE_ENABLED flag + GET /config/public`
+
+---
+
+## Phase J — Frontend billing foundation
+
+### Task 32: useBillingStore Zustand store + GET /billing/state integration
+
+**Outcome:** Frontend has a single source of truth for subscription / plan / feature state.
+
+**Contract — store shape:**
+
+```typescript
+// frontend/src/store/billingStore.ts
+interface BillingState {
+  subscription: {
+    status: 'trialing' | 'active' | 'past_due' | 'canceled' | 'incomplete' | 'complimentary'
+    plan: string
+    current_period_start: string | null  // ISO
+    current_period_end: string | null    // ISO
+    cancel_at_period_end: boolean
+    seat_limit: number | null
+    has_pro_entitlement: boolean
+    is_paid: boolean
+  } | null
+  planBilling: {
+    display_name: string
+    description: string | null
+    monthly_price_cents: number | null
+    annual_price_cents: number | null
+  } | null
+  planLimits: Record<string, unknown>
+  enabledFeatures: Record<string, boolean>
+  isLoading: boolean
+  error: string | null
+}
+
+interface BillingStore extends BillingState {
+  fetch: () => Promise<void>
+  refetch: () => Promise<void>
+  reset: () => void
+}
+```
+
+**Behavior:**
+
+- Auto-fetches on auth-store login (subscribe to `authStore`).
+- Auto-resets on logout.
+- Polls every 60s while the dashboard is mounted (simple `useInterval` in a top-level component is fine — no SSE for v1).
+- `refetch()` is exposed for explicit refresh after Stripe Checkout success-redirect.
+
+**Acceptance criteria:**
+
+- [ ] Initial state is null/empty; populates after first successful fetch.
+- [ ] 401 from `/billing/state` triggers logout via existing axios interceptor (no special handling needed).
+- [ ] Polling disabled when no user is logged in.
+
+**Integration tests (Vitest):**
+
+- `useBillingStore fetches on login and populates subscription`
+- `useBillingStore resets on logout`
+- `useBillingStore refetch overwrites stale data`
+
+**Commit:** `feat(billing): add useBillingStore and /billing/state integration`
+
+---
+
+### Task 33: useFeature, useFeatureLimit, useTrialBanner hooks
+
+**Outcome:** Components can ask "is this feature on?" / "how many sessions left?" / "what stage is the trial in?" without re-implementing the read.
+
+**Contract — hook signatures:**
+
+```typescript
+// useFeature: enabled boolean for a feature key
+function useFeature(flagKey: string): boolean
+
+// useFeatureLimit: progress against a quantitative limit
+function useFeatureLimit(field: keyof PlanLimits): {
+  used: number       // from /api/v1/usage/{field} (lazy fetch, cached 60s)
+  limit: number | null
+  percentage: number | null  // null when limit is null (unlimited)
+  isAtLimit: boolean
+  isLoading: boolean
+}
+
+// useTrialBanner: derives stage from subscription state
+function useTrialBanner(): {
+  stage: 'pristine' | 'warning' | 'urgent' | 'expired' | 'complimentary' | 'paid' | 'past_due' | 'canceled' | null
+  daysRemaining: number | null
+}
+```
+
+**Stage derivation:**
+- `subscription.status === 'complimentary'` → `complimentary`
+- `subscription.status === 'active'` → `paid`
+- `subscription.status === 'past_due'` → `past_due`
+- `subscription.status === 'canceled'` → `canceled`
+- `subscription.status === 'trialing'` AND `current_period_end > now()` → `pristine` (>3 days), `warning` (1–3), `urgent` (<1)
+- `subscription.status === 'trialing'` AND `current_period_end <= now()` → `expired`
+
+**Acceptance criteria:**
+
+- [ ] `useFeatureLimit` does NOT block render — returns `isLoading=true` until usage data arrives.
+- [ ] `useTrialBanner` returns `null` when subscription is null (no flicker on initial load).
+- [ ] All three hooks subscribe to `useBillingStore` such that updates propagate without manual refetch.
+
+**Integration tests (Vitest):**
+
+- `useFeature returns false when flag absent`
+- `useFeatureLimit transitions isLoading → loaded`
+- `useTrialBanner stage matches subscription state matrix`
+
+**Commit:** `feat(billing): add useFeature, useFeatureLimit, useTrialBanner hooks`
+
+---
+
+### Task 34: FeatureGate, UpgradePrompt, EmailVerificationGate components
+
+**Outcome:** Three drop-in components that handle the most common gating patterns. Component implementation details (props, layout, Tailwind classes) are at implementer's discretion as long as the API holds.
+
+**Contracts:**
+
+```tsx
+// FeatureGate: render children if feature enabled, else fallback (default <UpgradePrompt />)
+<FeatureGate feature="psa_integration" fallback={<UpgradePrompt feature="psa_integration" />}>
+  <PsaConfigPanel />
+</FeatureGate>
+
+// UpgradePrompt: standardized "this feature is on Pro" affordance with CTA
+<UpgradePrompt feature="psa_integration" />  // resolves display name + plan name internally
+
+// EmailVerificationGate: wraps protected content; renders <EmailVerificationWall /> past grace
+<EmailVerificationGate>
+  <DashboardContent />
+</EmailVerificationGate>
+```
+
+**Behavior:**
+
+- `<FeatureGate>` reads from `useFeature(feature)`. Server-side check via `require_feature` is the security boundary; this is UX.
+- `<UpgradePrompt>` CTA links to `/account/billing/select-plan`.
+- `<EmailVerificationGate>` reads `users.email_verified_at` + `users.created_at` from `authStore.user`. Day 1–6 unverified renders children (banner shown elsewhere). Day 7+ unverified renders `<EmailVerificationWall>`.
+
+**Acceptance criteria:**
+
+- [ ] All three components are exported from `frontend/src/components/common/`.
+- [ ] No CSS-in-JS — Tailwind classes per existing pattern.
+- [ ] Lock icon + greyed style for `<UpgradePrompt>` matches the design system tokens (no `bg-accent` for non-interactive elements per design lessons).
+
+**Integration tests (Vitest + Playwright):**
+
+- `FeatureGate renders children when flag enabled, fallback when disabled` (Vitest)
+- `UpgradePrompt CTA navigates to /account/billing/select-plan` (Vitest)
+- `EmailVerificationGate renders wall on day 8 unverified user` (Vitest, mocked authStore)
+
+**Commit:** `feat(billing): add FeatureGate, UpgradePrompt, EmailVerificationGate components`
+
+---
+
+## Phase K — Auth surfaces
+
+### Task 35: Register page redesign with OAuth buttons + invite-code-optional
+
+**Outcome:** New register flow supports email+password OR Google OR Microsoft, with promo code field collapsed (deferred per spec) and the legacy invite-code field invisible when `SELF_SERVE_ENABLED`.
+
+**Contract:**
+
+Frontend route stays `/register`. Component lives at `frontend/src/pages/RegisterPage.tsx` (modified, not replaced).
+
+Top-of-page CTAs:
+- **"Continue with Google"** button → opens OAuth window → on callback, POSTs `code` to `POST /api/v1/auth/google/callback` → stores tokens via existing auth-store login flow → redirects to `/welcome` (new user) or `/` (returning).
+- **"Continue with Microsoft"** button → same shape against `/auth/microsoft/callback`.
+- **"or sign up with email"** divider, then existing email + password form.
+
+Removed/conditional:
+- **Invite-code field** — hidden when `useAppConfig().self_serve_enabled === true`. When the flag is off, the existing required-invite-code flow runs unchanged.
+- **Promo-code field** — not in v1 (deferred per spec). UI should NOT include it.
+
+`/register?plan=pro` query param is captured into `localStorage` (`rf-intended-plan`) so `BillingService.start_trial` (already runs on Pro by default) can later be enriched OR the in-app picker can preselect.
+
+**Acceptance criteria:**
+
+- [ ] Email+password register call still works; auto-sends verification email per Phase 1 Task 20.
+- [ ] OAuth callback creates User + Account + Subscription per Phase 1 Task 17/18; lands on `/welcome`.
+- [ ] When self-serve disabled: invite-code flow visible, OAuth buttons hidden.
+- [ ] When self-serve enabled: invite-code field hidden, OAuth buttons visible.
+- [ ] Existing test users (`engineer@resolutionflow.example.com` etc.) can still log in via `/login` unchanged.
+
+**Integration tests (Playwright):**
+
+- `register email+password → verification email queued → land on /welcome`
+- `register via Google OAuth (mocked provider) → land on /welcome`
+- `register page hides OAuth + shows invite-code field when self_serve_enabled is false`
+
+**Commit:** `feat(auth): redesign /register with OAuth buttons; hide invite-code under flag`
+
+---
+
+### Task 36: AcceptInvitePage at /accept-invite?code=...
+
+**Outcome:** Invitee from email can join an existing account with set-password OR Google OR Microsoft.
+
+**Contract:**
+
+New top-level route `/accept-invite?code=<32-char-code>`. Component at `frontend/src/pages/AcceptInvitePage.tsx`.
+
+Flow:
+1. On mount, `GET /api/v1/accounts/invites/{code}/lookup` (NEW endpoint — see acceptance criteria) returns `{account_name, inviter_name, invited_email, role}` or 404/410 (expired/revoked/used).
+2. Render: "Join {account_name} on ResolutionFlow" + email locked to `invited_email` + three sign-in options (set password, Google, Microsoft).
+3. On submit, POST to existing `/auth/register` with `account_invite_code` and the email matching `invited_email` (per Phase 1 Task 20 enforcement).
+4. OAuth path: launch provider with state including the invite code; callback POSTs `{code, account_invite_code, invited_email}` to handle linking.
+5. Success → land on `/?welcome=teammate` (suppresses welcome wizard for invitees per spec).
+
+**Backend addition needed (small):**
+
+```
+GET /api/v1/accounts/invites/{code}/lookup
+  → 200 {account_name, inviter_name, invited_email, role}
+  → 404 invite_invalid_or_expired_or_revoked
+```
+
+This is a public endpoint (no auth) reading account-scoped data, so uses `_admin_session_factory()` per the Phase 4 RLS pattern.
+
+**Acceptance criteria:**
+
+- [ ] Invalid/expired/revoked codes show a clear "ask {inviter} to resend" message with a link to email the inviter (via `mailto:`).
+- [ ] Email field is locked to `invited_email` — frontend doesn't even render an editable input.
+- [ ] OAuth path requires the provider's email to match `invited_email`; mismatch returns the same `invite_email_mismatch` error from Phase 1.
+- [ ] Successful accept lands on `/?welcome=teammate`; the dashboard shows a "Welcome to {account_name}" toast and a checklist with "Setup shop" + "Invite a teammate" auto-marked done.
+
+**Integration tests (Playwright):**
+
+- `accept invite with email/password → join existing account → land on /?welcome=teammate`
+- `accept invite with Google OAuth (matching email) → land on dashboard`
+- `accept invite with mismatched email → see invite_email_mismatch error`
+- `accept invite with expired code → see resend message`
+
+**Commit:** `feat(auth): add /accept-invite page + lookup endpoint`
+
+---
+
+### Task 37: Email verification surfaces — banner, wall, /verify-email route
+
+**Outcome:** UI for the soft 7-day grace + day-7 wall.
+
+**Contract:**
+
+- **`<EmailVerificationBanner />`** — thin top-of-dashboard bar visible when `users.email_verified_at IS NULL` AND grace not expired. "Resend" link calls existing `POST /auth/email/send-verification`.
+- **`<EmailVerificationWall />`** — full-content replacement when grace expired. Same "Resend" CTA + a "Sign out" button.
+- **`/verify-email?token=...`** — frontend route that calls existing `POST /auth/email/verify` and shows success/error state. On success, refreshes the auth store and redirects to `/?verified=1` toast.
+
+**Acceptance criteria:**
+
+- [ ] Banner contrasts well in dark theme (use `bg-warning-dim` per design tokens, not custom colors).
+- [ ] Wall has a "Sign out" button so a user with a typo'd email can recover.
+- [ ] Verification success toast does not double-fire on remount.
+- [ ] If user is already verified when hitting `/verify-email`, the page shows "Already verified" rather than failing.
+
+**Integration tests (Playwright):**
+
+- `unverified day-1 user sees banner on dashboard`
+- `unverified day-8 user sees wall, can sign out, can resend`
+- `clicking verification link verifies and redirects to dashboard with toast`
+
+**Commit:** `feat(auth): add email verification banner, wall, /verify-email page`
+
+---
+
+## Phase L — Welcome wizard
+
+### Task 38: Wizard scaffold + Step 1 (Your shop)
+
+**Outcome:** Authed users at `/welcome` see a deliberate first-impression flow that captures shop context.
+
+**Routing:**
+
+```
+/welcome              → redirects to next incomplete step or "/" if done
+/welcome/step-1       → "Your shop"
+/welcome/step-2       → "Your PSA"
+/welcome/step-3       → "Invite your team"
+```
+
+A top-level `<WelcomeRouter />` reads `users.onboarding_step_completed` + `users.onboarding_dismissed` from authStore and dispatches:
+
+| State | Redirect |
+|---|---|
+| `onboarding_dismissed === true` | `/` |
+| `onboarding_step_completed >= 3` | `/` |
+| `onboarding_step_completed === null/0` | `/welcome/step-1` |
+| `onboarding_step_completed === 1` | `/welcome/step-2` |
+| `onboarding_step_completed === 2` | `/welcome/step-3` |
+
+**Step 1 fields (per spec):**
+
+- Company name (pre-filled from `accounts.name`, editable)
+- Team size: select from `1-2 / 3-5 / 6-10 / 11-25 / 26+`
+- Your role: select from `Owner / Lead Tech / Tech / Other`
+
+**Step 1 actions:**
+- **Continue** → PATCH `/users/me/onboarding-step` `{step: 1, action: "complete", data: {...}}` → `/welcome/step-2`
+- **Skip** → PATCH `{step: 1, action: "skip"}` → `/welcome/step-2`
+- **Skip the rest** → POST `/users/me/onboarding-dismiss-rest` → `/`
+
+**Acceptance criteria:**
+
+- [ ] Each navigation persists state server-side before transition; refresh resumes correctly.
+- [ ] Skip-the-rest is a quiet text link, not a primary button.
+- [ ] Email-verification banner is visible above the wizard if user is unverified (banner persists into wizard).
+
+**Integration tests (Playwright):**
+
+- `new user lands on /welcome/step-1 after register`
+- `step-1 Continue with all fields filled persists and advances`
+- `step-1 Skip-the-rest dismisses and lands on /`
+- `refresh in middle of step-1 returns to step-1 with prior data still in form (or empty if not yet saved)`
+
+**Commit:** `feat(onboarding): add welcome wizard scaffold + Step 1 (Your shop)`
+
+---
+
+### Task 39: Wizard Steps 2 (Your PSA) and 3 (Invite team)
+
+**Outcome:** Wizard is complete; users can finish or skip individual steps.
+
+**Step 2 fields (per spec):**
+
+- PSA selection: tiles for `ConnectWise / Autotask / HaloPSA / No PSA yet`. Selecting one shows a quiet inline "Connect now" link that navigates to `/account/integrations` (out of wizard).
+
+**Step 3 fields (per spec):**
+
+- Email input rows × 3, with "+ Add another" up to 10 max
+- Per-row role select: default "Tech" (maps to `engineer`), with "Viewer" option
+- "Skip" and "Skip the rest" links
+
+**Step 3 submit behavior:**
+
+- POST `/api/v1/accounts/me/invites/bulk` with the populated rows.
+- Then PATCH `/users/me/onboarding-step` `{step: 3, action: "complete"}`.
+- On success → `/?welcome=true` (shows a "You're all set" toast).
+- Bulk endpoint's `failed[]` array displayed inline next to the failed email; user can retry.
+
+**Acceptance criteria:**
+
+- [ ] Step 2 default action is "Continue" (not "Connect now"); the inline credential entry is intentionally NOT in the wizard.
+- [ ] Step 3 invites are sent (email send happens server-side per Phase 1 Task 22).
+- [ ] Empty Step 3 + Skip = no invites sent; step still advances.
+- [ ] Each step's persistence is independent — navigating back via browser back button respects `onboarding_step_completed`.
+
+**Integration tests (Playwright):**
+
+- `step-2 select ConnectWise → continue → primary_psa is set in /billing/state-equivalent or /auth/me`
+- `step-3 enter 2 emails → invites visible in /accounts/me/invites + emails sent`
+- `step-3 with one bad email shows partial success, user can retry`
+- `wizard end-to-end: register → step-1 → step-2 → step-3 → dashboard with success toast`
+
+**Commit:** `feat(onboarding): add wizard Steps 2 (PSA) and 3 (Invite team)`
+
+---
+
+## Phase M — Dashboard redesign
+
+### Task 40: Topbar trial pill + email verification banner integration
+
+**Outcome:** Every authed page shows the right billing-state pill in the topbar.
+
+**Contract — `<TrialPill />` placement:**
+
+Mounts inside `AppLayout` topbar. Reads `useTrialBanner()`:
+
+| Stage | Pill |
+|---|---|
+| `pristine` | "Pro trial · Nd" — info color |
+| `warning` (≤3d) | "Pro trial · Nd" — warning amber |
+| `urgent` (≤1d) | "Pro trial · today" — urgent (warning amber, slightly more saturated) |
+| `expired` | "Trial expired — pick a plan" — clickable → `/account/billing/select-plan` |
+| `paid` | tier display name (e.g., "Pro") — quiet |
+| `complimentary` | "Complimentary Pro" — friendly tag, no CTA |
+| `past_due` | "Payment failed — update card" — clickable → `/account/billing` |
+| `canceled` | "Reactivate" — clickable → `/account/billing/select-plan` |
+| `null` | hidden |
+
+**Acceptance criteria:**
+
+- [ ] Color tokens are existing design-system tokens (`--accent` / `--warning` / etc.) — no custom colors.
+- [ ] Pill is keyboard-focusable for clickable variants.
+- [ ] EmailVerificationBanner from Task 37 sits BELOW the topbar, ABOVE main content. Both can coexist.
+- [ ] Mobile: pill collapses to icon + tooltip when topbar is too narrow.
+
+**Integration tests (Playwright):**
+
+- `complimentary user sees "Complimentary Pro" pill`
+- `trialing user with 12 days remaining sees "Pro trial · 12d"`
+- `expired-trial user sees clickable "Trial expired" pill`
+- `past_due user sees clickable "Payment failed" pill`
+
+**Commit:** `feat(dashboard): add TrialPill in AppLayout topbar`
+
+---
+
+### Task 41: Next-step card + checklist redesign + dashboard wiring
+
+**Outcome:** Dashboard surfaces a single "next thing to do" card; full checklist available behind a toggle. Replaces the existing `OnboardingChecklist` component.
+
+**Contract:**
+
+- **`<NextStepCard />`** at top of dashboard content (below banner). Reads from existing `/users/onboarding-status` payload (extended in Phase 1 to drop SOLO/TEAM split — see Phase 1 Task wiring if needed; if not done, do it here).
+- Shows the highest-priority incomplete item with a primary CTA button. Items in priority order:
+  1. Verify your email (only if unverified — hidden for OAuth signups)
+  2. Set up your shop (`onboarding_step_completed >= 1`)
+  3. Run your first FlowPilot session (existing `ran_session` check)
+  4. Connect your PSA (existing `connected_psa` check)
+  5. Invite a teammate (extend existing `invited_teammate` check)
+  6. Pick a plan — surfaces near trial end (only when stage is `warning` / `urgent` / `expired`)
+- Below the card, "Show all setup steps" toggle expands a full checklist view (single list, no SOLO/TEAM split per spec).
+
+**OnboardingChecklist component changes:**
+
+- Remove `SOLO_ITEMS` / `TEAM_ITEMS` split — single unified list.
+- Drop the stale `tried_ai_assistant` / "Check out the Script Builder" item entirely.
+- Add "Pick a plan" item that shows when trial-banner stage is `warning` or later.
+
+**Backend addition:**
+
+`/api/v1/users/onboarding-status` (existing endpoint) response shape extended:
+
+```python
+class OnboardingStatus(BaseModel):
+    # existing
+    created_flow: bool
+    ran_session: bool
+    exported_session: bool
+    invited_teammate: bool
+    connected_psa: bool
+    is_team_user: bool         # KEEP — internal logic only; no UI bifurcation
+    dismissed: bool            # users.onboarding_dismissed
+    # NEW
+    email_verified: bool
+    shop_setup_done: bool      # users.onboarding_step_completed >= 1
+    # REMOVED from new code paths (kept in payload for backward-compat during deploy):
+    # tried_ai_assistant: bool
+```
+
+**Acceptance criteria:**
+
+- [ ] Old `OnboardingChecklist` widget is replaced wholesale on the dashboard route. Other pages that referenced it (none found in current code, but confirm via grep) are updated or unaffected.
+- [ ] Next-step card disappears when all items are done OR `onboarding_dismissed=TRUE`.
+- [ ] No SOLO/TEAM bifurcation in the checklist UI.
+- [ ] Stale "Script Builder" item is gone.
+
+**Integration tests (Playwright):**
+
+- `dashboard for new user surfaces "Verify your email" as next step`
+- `after verifying, next step is "Set up your shop"`
+- `after wizard step 1, next step is "Run your first FlowPilot session"`
+- `"Show all setup steps" expands to a 6-item list with no SOLO/TEAM headers`
+- `Pick-a-plan appears at trial day 12, urgent at day 13, primary at day 14`
+
+**Commit:** `feat(dashboard): replace checklist with next-step card + unified list`
+
+---
+
+## Phase N — Public surfaces
+
+### Task 42: Pricing page (B-style) at /pricing
+
+**Outcome:** Public pricing page lives at `/pricing`, gated by feature flag.
+
+**Contract:**
+
+Public route. Component at `frontend/src/pages/PricingPage.tsx`. Reads `plan_billing` data via a new public endpoint:
+
+```
+GET /api/v1/plans/public
+  → 200 [
+    {
+      plan: string,
+      display_name: string,
+      description: string | null,
+      monthly_price_cents: number | null,
+      annual_price_cents: number | null,
+      max_seats: number | null,        // from plan_limits
+      sort_order: number,
+      is_public: true,                 // filtered server-side
+    },
+    ...
+  ]
+```
+
+Page sections (per spec B):
+1. Hero (one-liner + reverse-trial reassurance)
+2. Three plan cards (Starter / Pro recommended / Enterprise) — Pro card has "Recommended" badge; Enterprise card has "Talk to sales" CTA → `/contact-sales`
+3. Comparison table (which features in which plan) — driven by feature flag display names
+4. Single testimonial slot (placeholder until real testimonial available)
+5. Trust strip — security/compliance copy
+
+**Acceptance criteria:**
+
+- [ ] Returns 404 when `self_serve_enabled === false`.
+- [ ] Plan cards show prices from `plan_billing.monthly_price_cents`. Enterprise card hides price.
+- [ ] "Start free trial" buttons on Starter/Pro link to `/register?plan=pro` (or starter).
+- [ ] "Talk to sales" on Enterprise links to `/contact-sales`.
+- [ ] Trust strip claims should be honest — see spec open-risks #7 (GDPR DPA) and #7b (SOC2). If those aren't ready by cutover, copy in this task uses softer language (e.g., "Built on Stripe + AWS · Encrypted in transit and at rest").
+
+**Integration tests (Playwright):**
+
+- `unauth user sees pricing page when self_serve_enabled is true`
+- `pricing page → "Start free trial" → /register?plan=pro`
+- `pricing page → "Talk to sales" → /contact-sales`
+- `pricing page returns 404 when self_serve_enabled is false`
+
+**Commit:** `feat(pricing): add /pricing page (B-style)`
+
+---
+
+### Task 43: Talk-to-sales form at /contact-sales + landing-page CTA
+
+**Outcome:** Enterprise prospects have a clear path; `LandingPage.tsx` gets a "See pricing" CTA.
+
+**Contract:**
+
+`/contact-sales` route with form posting to `POST /sales-leads` (Phase I Task 29).
+
+Form fields:
+- Name (required)
+- Work email (required)
+- Company (required)
+- Team size (select; same buckets as wizard Step 1 + a "more than 26" option)
+- "What brought you here?" (textarea, optional)
+- Submit button
+
+After submit:
+- Confirmation page: "Thanks — we'll reach out within 1 business day. Want to skip ahead? [Calendly link]"
+- Calendly link is a config string (`VITE_CALENDLY_URL`); when unset, link section is hidden.
+
+`LandingPage.tsx` modification:
+- Add a prominent "See pricing" CTA near the existing "Get started" CTA.
+- Both visible regardless of `self_serve_enabled` (see-pricing 404s if flag off, landing keeps existing behavior). Actually: gate the See-pricing CTA behind `useAppConfig().self_serve_enabled` so we don't show a button that 404s.
+
+**Acceptance criteria:**
+
+- [ ] Form blocks duplicate submissions client-side (disable button while in flight).
+- [ ] PostHog `talk_to_sales_form_submitted` event fires with `source: 'pricing_page' | 'landing_page'` based on referrer.
+- [ ] Calendly link block hides when `VITE_CALENDLY_URL` unset.
+
+**Integration tests (Playwright):**
+
+- `submit /contact-sales form → see confirmation page → /sales-leads has new row`
+- `landing page shows "See pricing" CTA when self_serve_enabled, hides when off`
+
+**Commit:** `feat(sales): add /contact-sales form + landing page CTA`
+
+---
+
+### Task 44: Beta-signup deprecation
+
+**Outcome:** The legacy `beta_signup.py` endpoint redirects to register; existing waitlist gets a heads-up email.
+
+**Contract:**
+
+- `POST /api/v1/beta-signup` (existing) → keep mounted but return `307 Temporary Redirect` to `/register?from=beta`.
+- One-off admin script `scripts/email_beta_waitlist.py` that reads existing `beta_signup` table and queues "we've launched" emails to each.
+- Don't drop the table; archive in place.
+
+**Acceptance criteria:**
+
+- [ ] Existing tests against `/beta-signup` either updated to expect 307 or removed.
+- [ ] Script is idempotent (uses an `email_sent_at` field on the beta-signup row, adding it via migration if needed).
+
+**Integration tests:**
+
+- `POST /beta-signup returns 307 to /register?from=beta`
+
+**Commit:** `feat(sales): redirect beta-signup to /register; queue waitlist emails`
+
+---
+
+## Phase O — Cutover
+
+### Task 45: Stripe live-mode setup checklist (manual)
+
+**Outcome:** Stripe live-mode is configured and matches test mode. Manual step; this task tracks completion.
+
+**Checklist:**
+
+- [ ] In Stripe Dashboard (live mode):
+  - [ ] Create Products: ResolutionFlow Starter, ResolutionFlow Pro, ResolutionFlow Enterprise.
+  - [ ] Create monthly + annual recurring Prices for Starter and Pro.
+  - [ ] Enterprise has no Prices in the catalog (sales-created per customer).
+  - [ ] Enable Customer Portal: update payment method, cancel subscription, view invoices. Disable plan-switching from the portal.
+  - [ ] Register webhook endpoint at `https://api.resolutionflow.com/api/v1/webhooks/stripe` with events: `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted`, `invoice.payment_failed`, `invoice.payment_succeeded`.
+  - [ ] Save the live webhook signing secret.
+- [ ] In Railway prod environment variables:
+  - [ ] `STRIPE_SECRET_KEY` (live mode key, `sk_live_...`)
+  - [ ] `STRIPE_WEBHOOK_SECRET` (live signing secret)
+  - [ ] `STRIPE_PUBLISHABLE_KEY` (live publishable key) → `VITE_STRIPE_PUBLISHABLE_KEY` for frontend builds
+  - [ ] `OAUTH_REDIRECT_BASE` = `https://resolutionflow.com`
+  - [ ] `GOOGLE_CLIENT_ID` / `GOOGLE_CLIENT_SECRET` for prod Google OAuth app (separate from dev/test)
+  - [ ] `MS_CLIENT_ID` / `MS_CLIENT_SECRET` for prod Microsoft OAuth app
+- [ ] Run `python -m scripts.sync_stripe_plan_ids` (Phase 1 Task 6 referenced; create if not existing) to populate `plan_billing` rows with live Stripe IDs:
+  - [ ] Pro monthly + annual price IDs
+  - [ ] Starter monthly + annual price IDs (if Starter is in scope; see open risk #14)
+  - [ ] Enterprise: stripe_product_id only, no price IDs
+
+**Acceptance criteria:**
+
+- [ ] Live webhook receives a test event (use Stripe CLI's `stripe trigger checkout.session.completed` against the live endpoint with a test customer) and is logged in `stripe_events`.
+- [ ] `plan_billing` rows query returns expected Stripe IDs for Pro tier.
+
+**No commit** — this is a deploy-time operation.
+
+---
+
+### Task 46: Internal validation pass (test mode → soft cutover via per-email allowlist)
+
+**Outcome:** Real flow exercised end-to-end against the prod backend with `SELF_SERVE_ENABLED=false`, gated to internal testers only.
+
+**Per-email allowlist mechanism:**
+
+Backend reads `INTERNAL_TESTER_EMAILS` env var (comma-separated). When `SELF_SERVE_ENABLED=false` AND `current_user.email` is in the list, treat the user as if the flag were on (e.g., bypass invite-code requirement, expose pricing page via a header check). For frontend, the `/config/public` endpoint returns `self_serve_enabled: true` for these specific authenticated users.
+
+**Validation scenarios:**
+
+- [ ] Email signup → wizard step-by-step → first FlowPilot session run → trial-end synthetic time (DB query: `UPDATE subscriptions SET current_period_end = now() - interval '1 day' WHERE account_id = ...`) → plan picker → Stripe Checkout (test card `4242 4242 4242 4242`) → webhook → status='active'.
+- [ ] Google sign-in (real Google account) → `/welcome` → wizard → dashboard.
+- [ ] Microsoft sign-in (real M365 account) → same flow.
+- [ ] Invite-by-email: existing tester invites a teammate → teammate receives email → clicks link → `/accept-invite` → set password → joins account → lands on `/?welcome=teammate`.
+- [ ] Email match enforcement: try to register with `account_invite_code` and a different email → see `invite_email_mismatch`.
+- [ ] Past-due simulation: use Stripe test card `4000 0000 0000 0341` → first invoice succeeds, next charge declines → `subscription_status='past_due'` → topbar pill changes → user can update card via Customer Portal.
+- [ ] Pilot complimentary: log in as an existing pilot account → see "Complimentary Pro" pill, no walls, no nudges.
+- [ ] Webhook signature failure: send a forged webhook → 400 + log entry.
+- [ ] OAuth-only user attempts password login: rejected with `use_oauth_provider`.
+
+**Acceptance criteria:**
+
+- [ ] All 9 scenarios pass in prod test mode with internal testers.
+- [ ] Errors logged during validation are reviewed and either fixed or documented.
+
+**No commit** — validation is a checklist of test runs.
+
+---
+
+### Task 47: Feature-flag flip + week-1 monitoring
+
+**Outcome:** `SELF_SERVE_ENABLED=true` and `VITE_SELF_SERVE_ENABLED=true` in prod. Public pricing page is live.
+
+**Cutover steps:**
+
+- [ ] Send pre-launch email to all pilot users via `EmailService.send_complimentary_account_announcement` (1-2 days before flip).
+- [ ] Schedule the flip during low-traffic hours.
+- [ ] Update Railway env vars: `SELF_SERVE_ENABLED=true` (backend), `VITE_SELF_SERVE_ENABLED=true` (frontend, requires redeploy since Vite bakes at build time).
+- [ ] Verify prod: pricing page returns 200; new user can register without invite code.
+- [ ] Announce launch (founder action; not eng).
+
+**Week-1 monitoring (PostHog dashboards):**
+
+- [ ] Funnel: `pricing_page_viewed → register_started → register_completed → email_verification_completed → welcome_wizard_completed → first_session_started`
+- [ ] OAuth method mix
+- [ ] Wizard skip rate per step
+- [ ] `feature_gate_blocked` count by `flag_key`
+- [ ] Trial conversion: `trial_modal_shown → checkout_completed`
+- [ ] Stripe webhook error rate (Sentry alert if > 1/hour)
+- [ ] `subscriptions.is_paid` audit query (manual SQL): confirm complimentary accounts are NOT counted in MRR
+
+**Rollback plan:**
+
+- Flip both flags back to `false`. Pricing page → 404. Register page → invite-code-required flow. Pilot complimentary status preserved (benign).
+- Stripe webhook handler stays live regardless.
+- Forward-only schema means nothing to revert at the DB level.
+
+**No commit** — this is a deploy + monitor task.
+

+
+## Self-Review
+
+**Spec coverage check (against `2026-05-05-self-serve-signup-onboarding-design.md`):**
+
+| Spec section | Covered by |
+|---|---|
+| §3.1 Pricing page | Task 42 |
+| §3.2 Register page redesign with OAuth + invite-code-optional | Task 35 |
+| §3.3 Welcome wizard (3 steps) | Tasks 38, 39 |
+| §3.4 Dashboard with topbar pill + next-step card | Tasks 40, 41 |
+| §3.5 Email verification surfaces | Task 37 |
+| §3.6 Trial-end conversion (in-app modal day 10, wall day 14) | Task 41 covers checklist; the modal is part of Task 40's TrialPill stage transitions + the dashboard's modal trigger via `useTrialBanner` — implementer's discretion to add a `<TrialEndingModal />` component if it emerges naturally |
+| §3.7 Plan picker → Stripe Checkout | Frontend page at `/account/billing/select-plan` lives within the dashboard area; Task 41's "Pick a plan" CTA navigates there. Component exists in scope of Task 40/41 — implementer's call on whether to split into its own file. |
+| §3.8 Past-due / dunning | Task 40 (TrialPill `past_due` stage) + Customer Portal link |
+| §3.9 Sales lead | Tasks 29, 43 |
+| §3.10 Owner transfer (existing) | No new task — surface in Account → Team page during dashboard work, implementer's discretion |
+| §4 BillingService.open_customer_portal | Task 27 |
+| §4 PATCH /users/me/onboarding-step | Task 28 |
+| §4 GET /billing/state consumed by frontend | Task 32 |
+| §4 useFeature/useFeatureLimit/useTrialBanner | Task 33 |
+| §4 FeatureGate / UpgradePrompt | Task 34 |
+| §4 Caching invalidation triggered from /admin/plan-limits | Task 30 |
+| §5 Beta-signup deprecation | Task 44 |
+| §5 SELF_SERVE_ENABLED dark launch | Task 31 |
+| §5 Stripe live-mode setup | Task 45 |
+| §5 Internal validation phase | Task 46 |
+| §5 Cutover + monitoring | Task 47 |
+
+**Gaps and judgment-calls (called out for implementer):**
+
+- **`<TrialEndingModal />` (day-10 in-app modal)** — left to implementer to decide whether it's its own task or rolled into Task 40. Spec is clear about behavior; component split is style.
+- **Plan picker page (`/account/billing/select-plan`)** — frontend page that calls `POST /billing/checkout-session` and redirects. Lives within Task 40/41 area; not its own task. Acceptance: "user can pick Starter/Pro + seats and be redirected to Stripe Checkout."
+- **Owner-transfer surface in Account → Team page** — existing endpoint, just needs UI. Implementer's call on which task absorbs this.
+- **`<TrialEndedWall />`** — referenced in spec; renders on dashboard route when trial expired. Lives in Task 40/41 area as a render-branch of the dashboard layout.
+
+**Placeholder scan:** none — every "implementer's discretion" call is bounded by a contract and acceptance criteria.
+
+**Type/contract consistency:**
+
+- `BillingState` shape in Task 32 matches `BillingStateResponse` from Phase 1 Task 24.
+- `PATCH /users/me/onboarding-step` payload in Task 28 matches the wizard's writes in Tasks 38, 39.
+- OAuth callback contract in Task 35 matches Phase 1 Task 17/18 endpoint shapes.
+- `<EmailVerificationGate>` in Task 34 reads from authStore; `<TrialPill>` in Task 40 reads from `useBillingStore`. Different sources, intentional (verification is on `User`, trial is on `Subscription`).
+
+---
+
+## Execution Handoff
+
+**Plan complete and saved to `docs/superpowers/plans/2026-05-06-self-serve-signup-phase-2-frontend-cutover.md`.**
+
+This plan is intentionally higher-altitude than Phase 1: contracts and acceptance criteria, not component-detail walkthroughs. Implementers exercise judgment on internal structure as long as contracts hold and integration tests pass.
+
+**Recommended execution sequence:**
+
+1. **Phase 1 first** (`2026-05-06-self-serve-signup-phase-1-backend.md`). Phase 2 depends on its endpoints.
+2. After Phase 1 lands, **execute Phase 2 phases I → O sequentially**. Each phase is one or a few mergeable PRs.
+3. **Cutover (Phase O)** is gated by Phase 1 + Phase 2 both green in prod test mode.
+
+**Two execution options for Phase 2:**
+
+**1. Subagent-Driven (recommended)** — fresh subagent per task with two-stage review. Higher-altitude tasks pair well with this since the subagent has room to make local design decisions inside the contract.
+
+**2. Inline Execution** — execute tasks in a long-running session using executing-plans, with checkpoints between phases.
+
+**Which approach?**

+# Self-Serve Signup & Onboarding — Design Spec
+
+**Date:** 2026-05-05
+**Status:** Draft (revised after review-findings pass; pending user re-review)
+**Author:** Michael Chihlas + Claude
+
+---
+
+## Overview
+
+Open ResolutionFlow to public self-serve signup with a 14-day reverse trial on Pro, Stripe-backed billing, a sales-assist lane for Enterprise, and a hybrid onboarding flow (3-step welcome wizard + dashboard with next-step card). The current invite-code-gated registration is removed; existing pilot users transition to a permanent `subscriptions.status='complimentary'` state. **The billing layer reuses existing infrastructure** (`subscriptions` + `plan_limits` + `feature_flags` + `plan_feature_defaults` + `account_feature_overrides` + `account_invites` + `email_verification_tokens`) — this spec adds only what's missing, not parallel structures.
+
+---
+
+## Decisions Made
+
+| Question | Decision |
+|---|---|
+| Trigger for redoing signup/onboarding | Open self-serve channel (D); must look trustworthy; must hook into payment processor cleanly |
+| Trial / payment model | A + E — reverse trial (14 days, no card upfront) + sales-assist lane for Enterprise |
+| Plan structure | Two self-serve tiers (Starter, Pro) per seat + sales-assist Enterprise. Defined via existing `plan_limits.plan` keys + a new `plan_billing` sibling table (Stripe IDs, prices, public catalog metadata). |
+| Payment processor | Stripe with hosted Checkout; no provider abstraction |
+| Auth strategy | Stay with custom auth. Extend existing email verification (auto-send on register, 7-day soft grace + dashboard wall). Add Google + Microsoft via new `oauth_identities` table; `users.password_hash` becomes nullable with explicit OAuth-only handling in login/change-password/reset. Extend existing `account_invites` (enforce email match at register, wire `EmailService` into create/bulk). |
+| Signup form scope | A — minimal form (treat all signups as team-of-1) |
+| Plan choice timing | X — defer; trial runs on full Pro; picker shown around day 12 and at trial-end |
+| Feature gating | **Reuse existing `feature_flags` + `plan_feature_defaults` + `account_feature_overrides`.** Admin via existing `/admin/plan-limits` + `/admin/feature-flags` endpoints. No new combined `/admin/plans` surface in v1. |
+| Onboarding shape | C — hybrid (3-step welcome wizard then dashboard with checklist) |
+| Welcome wizard layout | V2 — narrative 3 steps (Your shop, Your PSA, Invite your team) |
+| Dashboard first-run | C — topbar trial pill + single "next step" card (full checklist behind a "Show all" toggle) |
+| Email verification | Soft, 7-day grace, hard wall day 7; skipped entirely for OAuth signups (provider-attested). **Reuses existing `email_verification_tokens` table + `/auth/email/send-verification` + `/auth/email/verify`.** Backend enforcement via new `require_verified_email_after_grace` dep with path allowlist (auth, profile, billing) returns 403 when grace expires unverified. Frontend `<EmailVerificationWall />` is a UX layer over the same rule. |
+| Pricing page | B — pricing + light marketing context (comparison table + testimonial slot + trust strip) |
+| Trial-end conversion flow | A — quiet days 1-9, gentle nudges 10-13, hard wall day 14 with plan picker |
+| Trial expiry enforcement | **Replace `deps.py:109` auto-downgrade.** Expiry is computed at request time (`status='trialing' AND current_period_end < now()`); no mutation to `plan='free'`. New backend `require_active_subscription` dep with path allowlist returns 402 when locked. |
+| `is_paid` semantics | `subscriptions.is_paid` excludes `complimentary` so comp accounts don't inflate paid/MRR metrics. New `has_pro_entitlement` property covers "this account can access Pro features" (true for paid Pro + complimentary Pro + active trial). |
+| Billing state surface | **Separate `GET /billing/state` endpoint** feeding a new frontend `useBillingStore`. `/auth/me` stays user-focused. |
+| Teammate invite-accept | Set-password OR Google/Microsoft OAuth; email-locked **(enforced at `/auth/register` against `account_invites.email`)**; no welcome wizard for invitees. |
+| Existing pilot users | All transitioned to `subscriptions.status='complimentary'` on Pro — no nags, no walls, voluntary conversion path. |
+| Existing invite codes | Registration gate removed. Table preserved for historical pilots; `User.invite_code_id` retained for existing rows; not consumed at new signups. **No repurposing.** |
+| Promo codes | **Deferred from v1.** Add a new `promo_codes` table later if a launch campaign needs them. |
+
+---
+
+## Section 1 — System overview
+
+### What this delivers
+
+Public registration through `/pricing` → `/register` → `/welcome` → dashboard, with the billing substrate built almost entirely on existing infrastructure. New code is concentrated in (a) the OAuth surface, (b) Stripe-aware billing service + webhook handler, (c) the welcome wizard + dashboard redesign, and (d) the public-facing pricing page.
+
+### Four chunks of work
+
+1. **Front-of-funnel** — public `/pricing` page (B-style: comparison table + testimonial slot + trust strip), sales-lead capture form, reworked `/register` form with OAuth options.
+2. **Onboarding surfaces** — 3-step welcome wizard (V2: shop → PSA selection → invite team) firing immediately after register; redesigned dashboard with topbar trial pill + single "next-step" card (C-style); 6-item checklist (Verify email → Setup shop → Run first session → Connect PSA → Invite teammate → Pick a plan).
+3. **Billing integration over existing schema** — extend `plan_limits` with a sibling `plan_billing` table (Stripe IDs + public catalog metadata); seed Starter / Pro / Enterprise rows in `plan_limits`; seed `feature_flags` + `plan_feature_defaults` for the Pro/Starter gating split; add `subscriptions.status='complimentary'` value; replace `deps.py:109` trial-expiry mutation with computed checks; add a `BillingService`, Stripe webhook handler, and `require_active_subscription` dep. Reuses existing `/admin/plan-limits` and `/admin/feature-flags` admin surfaces.
+4. **Auth additions** — Google + Microsoft OAuth via a new `oauth_identities` table (`users.password_hash` becomes nullable). Extend existing `email_verification_tokens` flow with auto-send on register and a 7-day soft-grace dashboard wall. Extend existing `account_invites` to enforce email match at registration and to actually send the invitation email at create-time (today only resend sends).
+
+### What stays the same
+
+- Existing JWT auth + JTI refresh rotation
+- `Account` / `Team` / `User` model and the `is_super_admin` / `account_role` / `is_team_admin` permission hierarchy (with `account_role` enum `'owner' | 'admin' | 'engineer' | 'viewer'`)
+- Phase 4 RLS (subscription state lives on `subscriptions`, account-scoped — RLS rules already configured for it)
+- All product surfaces (FlowPilot, PSA integrations, sessions, flows)
+- `/admin/plan-limits` + `/admin/feature-flags` admin endpoints (extended, not replaced)
+- `/accounts/me/transfer-ownership` (existing — covers owner transfer, no longer flagged "out of scope")
+- `/accounts/me/invites` and `/me/invites/{id}/resend` (extended with email send + email-match enforcement)
+
+### What's deprecated
+
+- Invite-code-as-registration-gate. The `invite_codes` table is preserved (historical foreign keys from `users.invite_code_id`); the gate is removed at `/auth/register`.
+- `beta_signup.py` waitlist endpoint becomes a 307 redirect to `/register`.
+- The current SOLO/TEAM split in `OnboardingChecklist` (one unified list).
+- The "Check out the Script Builder" item mapped to the stale `tried_ai_assistant` key.
+- Custom card-collection forms (Stripe Checkout owns this).
+- The auto-downgrade-on-expired-trial logic in `deps.py:109` (replaced with non-mutating computed checks).
+
+### Sequencing principle
+
+The billing extensions (new columns, new dep, replacing the auto-downgrade) and the Stripe webhook handler are the longest pole and the most unfamiliar surface area. Build it first, ship it dark behind `SELF_SERVE_ENABLED=false`, then layer the funnel and onboarding surfaces once it's stable. Detailed phases live in the implementation plan.
+
+---
+
+## Section 2 — Data model
+
+### Schema additions (new, small)
+
+#### `oauth_identities`
+
+```
+id                     UUID PK
+user_id                UUID FK users
+provider               VARCHAR(20)   -- 'google' | 'microsoft'
+provider_subject       VARCHAR(255)  -- provider's stable user id
+provider_email_at_link VARCHAR(255)  -- email reported by provider at link time
+created_at, updated_at TIMESTAMP WITH TIME ZONE
+UNIQUE (provider, provider_subject)
+INDEX (user_id)
+```
+
+A user can have zero password (OAuth-only), one password, and 0+ OAuth identities. v1 ships with one identity per user (signup creates one row). Account linking is a future feature with no schema change required.
+
+#### `plan_billing` (sibling to `plan_limits`)
+
+```
+plan                       VARCHAR(50) PK FK plan_limits.plan
+display_name               VARCHAR(255) NOT NULL
+description                TEXT NULL
+monthly_price_cents        INTEGER NULL    -- nullable for Enterprise (custom)
+annual_price_cents         INTEGER NULL
+stripe_product_id          VARCHAR(255) NULL
+stripe_monthly_price_id    VARCHAR(255) NULL
+stripe_annual_price_id     VARCHAR(255) NULL
+is_public                  BOOLEAN NOT NULL DEFAULT TRUE
+is_archived                BOOLEAN NOT NULL DEFAULT FALSE
+sort_order                 INTEGER NOT NULL DEFAULT 0
+created_at, updated_at     TIMESTAMP WITH TIME ZONE
+```
+
+`plan_limits.plan` stays the canonical plan key. `plan_billing` carries the Stripe + public-catalog metadata. Joined into the existing `/admin/plan-limits` admin endpoint via the response schema (single PUT updates both tables in one transaction).
+
+#### `sales_leads`
+
+```
+id                  UUID PK
+email               VARCHAR(255) INDEXED
+name                VARCHAR(255)
+company             VARCHAR(255)
+team_size           VARCHAR(20)   -- range string from form
+message             TEXT
+source              VARCHAR(50)   -- 'pricing_page' | 'register_footer' | etc.
+posthog_distinct_id VARCHAR(255) NULL
+status              VARCHAR(20) DEFAULT 'new'  -- 'new' | 'contacted' | 'closed'
+created_at, updated_at
+```
+
+Global table. No RLS.
+
+#### `stripe_events`
+
+Webhook idempotency log. Global table.
+
+```
+id              VARCHAR(255) PK   -- Stripe event id
+event_type      VARCHAR(100) INDEXED
+processed_at    TIMESTAMP WITH TIME ZONE
+payload_excerpt JSONB
+```
+
+### Modifications to existing tables
+
+#### `subscriptions` — extend the status enum
+
+- New status value: `'complimentary'`. Status enum effectively becomes `'active' | 'trialing' | 'past_due' | 'canceled' | 'incomplete' | 'complimentary'`. The column is `String(50)` so no schema migration is required for the value itself; we update the value-level checks only.
+- `Subscription.is_active` already returns `True` for `('active', 'trialing')` — extend to include `'complimentary'`.
+- `Subscription.is_paid` (currently `plan in ('pro', 'team')`) → narrow to `plan in ('pro', 'team') AND status NOT IN ('complimentary',)`. Used for revenue / paid-customer / MRR calculations only.
+- New `Subscription.has_pro_entitlement` property: returns True for `(plan='pro' AND status IN ('active', 'complimentary'))` OR `(status='trialing' AND current_period_end > now())`. Used for "can this account access Pro features."
+
+These are model-level Python property changes plus tests; the underlying column type doesn't change.
+
+#### `users` — additions
+
+- `email_verified_at` already exists. No add. Email-verification flow uses it.
+- `password_hash` — **change `nullable=False` → `nullable=True`** to support OAuth-only users. Migration sets nullable; no data backfill needed (existing rows all have hashes).
+- `role_at_signup VARCHAR(50) NULL` — `'owner' | 'lead_tech' | 'tech' | 'other'` (welcome-wizard Step 1 captures this).
+
+The existing `users.onboarding_dismissed` field stays. **Add a new `users.onboarding_step_completed INTEGER NULL`** that tracks the highest wizard step the user has either completed or explicitly skipped (1, 2, or 3; NULL = haven't started). This is the only new column needed beyond `role_at_signup` and resolves the per-step skip ambiguity that derived data couldn't represent.
+
+Wizard state model:
+
+- User clicks **Continue** on a step → `onboarding_step_completed = step_number`. Step's data fields are written (e.g., Step 1 writes `users.role_at_signup` + `accounts.team_size_bucket`).
+- User clicks **Skip** on a step → `onboarding_step_completed = step_number`. Step's data fields stay NULL.
+- User clicks **Skip the rest** on any step → `users.onboarding_dismissed = TRUE` (whatever step they were on stays as `onboarding_step_completed = step_number - 1`).
+- Wizard is "done" when `onboarding_dismissed = TRUE` OR `onboarding_step_completed >= 3`.
+- `/welcome` redirect logic: if done, go to `/`; otherwise go to `/welcome/step-{onboarding_step_completed + 1 or 1}`.
+
+This makes "I intentionally skipped inviting teammates" representable separately from "I haven't reached Step 3 yet."
+
+#### `accounts` — additions for wizard data
+
+`accounts.name` (existing, `String(255) NOT NULL`) is reused for the wizard's "Company name" field — the wizard updates this row rather than a new column. Today `accounts.name` is populated at register-time from the user's input or a sensible default; the wizard lets the user correct it.
+
+New columns:
+
+- `team_size_bucket VARCHAR(20) NULL` — `'1-2' | '3-5' | '6-10' | '11-25' | '26+'`
+- `primary_psa VARCHAR(20) NULL` — `'connectwise' | 'autotask' | 'halopsa' | 'none'`
+
+No billing state on `accounts` — it lives on `subscriptions`.
+
+#### `account_invites` — small additions
+
+- `revoked_at TIMESTAMP WITH TIME ZONE NULL` — distinguishes revoked from used. Current model has only `used_at`; revoke (resend handler at `accounts.py:323`) currently deletes the row. Add `revoked_at` + change resend to soft-revoke for audit trail.
+- (Optional) `email_sent_at TIMESTAMP WITH TIME ZONE NULL` — track that the invite email was actually sent (today, only resend sends; create does not).
+
+`AccountInvite.is_used` and `is_valid` properties extend to consider `revoked_at`.
+
+### Migrations
+
+Single Alembic chain — manual revisions per Lesson 77. Multi-head heads on `main` (`070`, `c0f3a4b7e91d`, `024`) currently coexist; the new chain branches from the most recent and merges via `alembic upgrade heads` (plural).
+
+1. `add_oauth_identities.py` — new table.
+2. `users_password_hash_nullable.py` — alter to nullable.
+3. `users_add_role_at_signup_and_onboarding_step.py` — add `role_at_signup` and `onboarding_step_completed` columns.
+4. `accounts_add_wizard_columns.py` — add `team_size_bucket`, `primary_psa`. (`accounts.name` already exists; wizard writes to it.)
+5. `account_invites_add_revoked_at_and_email_sent_at.py` — add columns.
+6. `add_plan_billing.py` — new sibling table. Seeds Starter / Pro / Enterprise rows **with `stripe_product_id` / `stripe_*_price_id` left NULL**. Existing `plan_limits` rows already exist for `'free' / 'pro' / 'team'`; this migration aligns keys (`'starter' | 'pro' | 'enterprise'` if we rename, OR keep `'free' / 'pro' / 'team'` and treat `'free'` as the floor — open risk #14 captures the decision). Stripe IDs are populated **out-of-band** per environment via either the existing `/admin/plan-limits` PUT (extended to accept Stripe fields) or a one-off `python -m scripts.sync_stripe_plan_ids` admin command driven by env vars. **Migrations stay environment-agnostic** — they don't read live mode vs. test mode IDs.
+7. `seed_pro_starter_feature_flags.py` — register feature keys (`psa_integration`, `escalation_mode`, `script_builder`, `analytics_dashboards`, `knowledge_flywheel`, `team_admin_full`, `monthly_sessions` quantitative, `seats` quantitative, `sso`, `audit_log`) in `feature_flags`; populate `plan_feature_defaults` per the Pro/Starter split.
+8. `subscriptions_pilot_complimentary_backfill.py` — `UPDATE subscriptions SET status='complimentary', plan='pro' WHERE status NOT IN ('canceled')` for accounts that exist as of cutover. Single statement; ≤ 100 rows expected.
+9. `add_sales_leads_and_stripe_events.py` — two new tables.
+
+Forward-only. No down-migrations for the data backfills (step 8) — the original status values per account are not preserved.
+
+### RLS notes
+
+- `oauth_identities` is account-adjacent (joined via `user_id`), but RLS on `users` is admin-DB-only (per `deps.py` `get_current_user` uses `get_admin_db`). Treat `oauth_identities` the same — no per-tenant RLS policy; queries use admin session. Verify against current `users` table policy before merging.
+- `plan_billing` is global (joins `plan_limits.plan`, also global). No RLS.
+- `sales_leads`, `stripe_events` are global. No RLS.
+- `account_invites` already has its policy (account-scoped). No change.
+- `subscriptions` already has its policy. No change to schema means no RLS revision.
+
+### Index notes
+
+- `oauth_identities (provider, provider_subject)` UNIQUE — the OAuth callback's primary lookup.
+- `oauth_identities (user_id)` — list a user's identities.
+- `account_invites (revoked_at)` — partial filter for active-invites queries (`WHERE accepted_by_id IS NULL AND revoked_at IS NULL`).
+
+---
+
+## Section 3 — Funnel walkthrough
+
+### 1. Acquisition — `/pricing` (public)
+
+New route. B-style page: hero (one-liner + reverse-trial reassurance), three plan cards (Starter / Pro recommended / Enterprise), comparison table, testimonial slot (placeholder copy until a real one lands), trust strip ("SOC2 in progress · Stripe billing · GDPR DPA available"). Plan card data sourced from `plan_billing` filtered by `is_public=TRUE AND is_archived=FALSE`.
+
+- **Pro/Starter cards** → "Start free trial" → `/register?plan=pro` (or `?plan=starter`). Query param remembered through OAuth round-trip.
+- **Enterprise card** → "Talk to sales" → `/contact-sales` → POST `/sales-leads` → confirmation page with Calendly link in the email.
+- Existing `LandingPage.tsx` gets a "See pricing" CTA pointing here.
+
+### 2. Registration — `/register` (public, redesigned)
+
+Three sign-up paths on one page:
+
+- **Google sign-in** (primary button at top) → OAuth round-trip → `/auth/google/callback`. Backend creates a User if first time (`oauth_identities` row + Account + Subscription on Pro trial via `BillingService.start_trial`), marks `email_verified_at = now()` (provider-attested), redirects to `/welcome`.
+- **Microsoft sign-in** (button) → same flow with `provider='microsoft'`.
+- **Email + password** → POST `/auth/register`. Backend creates User (with `password_hash` set) + Account, calls `BillingService.start_trial`, sends verification email via existing `EmailService.send_email_verification_email` (auto-send is added; today the user has to click a button), returns JWT, frontend redirects to `/welcome`.
+
+Form fields: full name, work email, password (10+ chars, complexity rules per existing `UserCreate.password_complexity` validator). The current `invite_code` field on `UserCreate` is **removed at the registration gate** — public signups don't need one. The `account_invite_code` field is **kept** for the teammate-accept flow (see step 5b below).
+
+**Critical fix flagged in review:** registration with `account_invite_code` must enforce `user_data.email == account_invites.email` (today this is not enforced at `/auth/register`). The check happens in the register handler before the User is created; mismatch returns 400 with `{"error": "invite_email_mismatch"}`.
+
+### 3. Welcome wizard — `/welcome` (authed)
+
+Dedicated routes: `/welcome/step-1` (Your shop), `/welcome/step-2` (Your PSA), `/welcome/step-3` (Invite team). `/welcome` itself redirects to the lowest-numbered incomplete step. Each step persists immediately (PATCH endpoints — see Appendix A) so refreshes don't lose data and "Skip the rest" lands cleanly.
+
+- **Step 1 — Your shop**: company name (pre-filled from existing `accounts.name`, editable), team size bucket, your role. Saves to `accounts.name`, `accounts.team_size_bucket`, `users.role_at_signup`.
+- **Step 2 — Your PSA**: PSA selection only. Saves to `accounts.primary_psa`. Quiet "Connect now" link → `/account/integrations` (out of wizard); default action is **Continue**. No API key entry inside the wizard.
+- **Step 3 — Invite your team**: up to 3 email fields visible with "+ Add another" link; each invite defaults to "Tech" role; fully skippable. POSTs to a new `POST /accounts/me/invites/bulk` (thin wrapper around the existing single-create) **and sends invite emails per row**. The wizard's "Tech" UI label maps to `account_invites.role = 'engineer'` in the DB; "Viewer" UI label maps to `'viewer'` (per the existing CHECK constraint).
+
+**Critical fix flagged in review:** today, `POST /accounts/me/invites` (`accounts.py:257`) creates the row but does NOT send the email — only `/me/invites/{id}/resend` sends. The new flow wires `EmailService.send_account_invite_email` (existing method at `core/email.py:125`) into both create and bulk paths and stamps `email_sent_at` on success.
+
+Skip behavior: "Skip" on a step advances `users.onboarding_step_completed` (recording that the user saw and chose to skip that step). A separate "Skip the rest, take me to dashboard" link sets `users.onboarding_dismissed=TRUE` and redirects to `/`. Wizard is "done" when `onboarding_dismissed=TRUE` OR `onboarding_step_completed >= 3`. Auth-store reads this state on app load; `/welcome` redirects to the next incomplete step or to `/` if done.
+
+**Invited teammate variant:** invitee's email link goes to a frontend `/accept-invite?code=…` route that posts to `/auth/register` with `account_invite_code` (per the existing `UserCreate` schema). They land on `/?welcome=teammate` instead of the wizard, and get a brief "Welcome to {company}'s ResolutionFlow" toast. Re-running the wizard on already-onboarded users is suppressed via `users.onboarding_dismissed` OR derived data presence.
+
+### 4. Dashboard — `/` (authed, redesigned)
+
+- **Topbar pill** in `AppLayout` renders based on `subscriptions.status` and `current_period_end`:
+  - `trialing` AND `current_period_end > now()`: "Pro trial · Nd" — blue, amber when ≤3d remaining, red when ≤1d.
+  - `trialing` AND `current_period_end <= now()`: "Trial expired — pick a plan" (the locked state — no mutation has occurred at the DB level, just rendered differently).
+  - `active`: tier name only ("Pro" / "Starter") — no urgency.
+  - `complimentary`: "Complimentary Pro" — friendly tag, no CTA.
+  - `past_due`: "Payment failed — update card" — clickable, routes to `/account/billing`.
+  - `canceled`: pill becomes a "Reactivate" CTA.
+- **Next-step card** sits below the topbar. "Show all setup steps" link expands the full 6-item list inline.
+- **Email-verification banner** (when `users.email_verified_at IS NULL`): always-visible thin bar above the next-step card with a "Resend" link (POSTs to existing `/auth/email/send-verification`). On day 7 unverified, the dashboard route renders `<EmailVerificationWall />` instead of normal content.
+
+Checklist items (same for everyone — no SOLO/TEAM split):
+
+1. **Verify your email** — auto-completes on link click; hidden if signed up via OAuth.
+2. **Set up your shop** — completes when `users.onboarding_step_completed >= 1`.
+3. **Run your first FlowPilot session** — the wedge. Highlighted as the headline action when prior items are complete.
+4. **Connect your PSA** — auto-completes when first PSA connection saved. Pre-fills the provider based on welcome wizard selection.
+5. **Invite a teammate** — auto-completes when first invitation is sent.
+6. **Pick a plan** — appears earlier with low emphasis; turns urgent at ≤3 days remaining in trial.
+
+The stale `tried_ai_assistant` / "Check out the Script Builder" item is dropped entirely.
+
+### 5. Email verification — existing endpoints, new gating
+
+- `POST /auth/email/send-verification` (existing, `auth.py:621`) is auto-called by `/auth/register` — today the user has to click a button.
+- `POST /auth/email/verify` (existing, `auth.py:662`) consumes the token and sets `users.email_verified_at`.
+- The frontend `/verify-email?token=…` route calls the existing endpoint and shows a success or error state.
+- New: a frontend gating layer (`<EmailVerificationGate />`) wraps the dashboard route. Day 1-6 unverified shows the soft banner; day 7+ unverified renders `<EmailVerificationWall />`.
+- **Backend enforcement** via the new `require_verified_email_after_grace` dep (Section 4). The frontend wall is UX; the backend dep prevents direct API access by an unverified user past the 7-day grace. Mounted on every protected router; allowlists `/auth/*` (logout, verify, send-verification, password change), `/users/me`, and `/billing/*` so the user can still log out, verify, manage their profile, and convert to paid.
+
+No new endpoints, no new column. One new backend dep.
+
+### 6. Trial-end — Days 10-14
+
+- **Day 10**: in-app modal once ("Your trial ends in 4 days. Pick a plan to keep going."). Fired by `useTrialBanner` hook reading from `useBillingStore` (which polls `GET /billing/state`); per-user dismiss recorded in localStorage. Email day 10 + day 13 (`EmailService.send_trial_ending`).
+- **Day 14**: when `subscriptions.status='trialing'` AND `current_period_end < now()`, the dashboard route renders `<TrialEndedWall />` with the plan picker (Starter / Pro radio + seat count input). **No DB mutation occurs** — the lockout is computed at request time. Past sessions remain visible read-only for 30 days after `current_period_end` — computed at render time as `current_period_end + INTERVAL '30 days' < now()`. After that window, sessions are still in the database (no destructive action) but the dashboard hides them behind the wall until billing is added.
+
+### 7. Plan picker → Stripe Checkout — `/account/billing/select-plan` (authed)
+
+User picks Starter/Pro + seat count → POST `/billing/checkout-session` → backend calls `stripe.checkout.sessions.create` with:
+
+- `customer_email` from User
+- `line_items` (price_id from `plan_billing` × quantity = seats)
+- `mode='subscription'`
+- `subscription_data.trial_end = current_period_end` if still in trial (Stripe takes over the trial countdown)
+- `success_url=/account/billing?success=1`, `cancel_url=/account/billing/select-plan`
+
+Frontend redirects to Stripe-hosted Checkout. Stripe `checkout.session.completed` webhook → backend updates `subscriptions.status='active'`, sets `stripe_subscription_id`, `stripe_price_id`, refreshes `current_period_start/end` from the Stripe subscription, sets `seat_limit`. Idempotency via `stripe_events.id`.
+
+Success URL renders dashboard with "Pro active 🎉" toast.
+
+### 8. Past-due / dunning
+
+Stripe `invoice.payment_failed` webhook → `subscriptions.status='past_due'`. Topbar pill flips to "Payment failed — update card" linking to `/account/billing`, which uses Stripe's Customer Portal for card updates and cancellation. Dashboard remains accessible during the dunning window (Stripe default: 4 retries over 3 weeks). Account locks via `require_active_subscription` only at `canceled`.
+
+### 9. Sales lead — `/contact-sales` (public)
+
+Form posts to `/sales-leads` → creates row + sends email to `sales@resolutionflow.com` + emits PostHog event. Confirmation page: "Thanks — we'll reach out within 1 business day. Want to skip ahead? [Calendly link]." The Calendly link is a config string, not a calendar integration in v1.
+
+### 10. Owner transfer (existing — noted)
+
+Owner transfer is supported via the existing `POST /accounts/me/transfer-ownership` (`accounts.py:150`). The pricing-page Enterprise tier and the Account → Team page in the redesigned dashboard surface this for owners who need to hand off the account. **Not flagged as out-of-scope risk** as it was in the prior draft.
+

+
+## Section 4 — Billing substrate + Stripe integration
+
+### `app.services.billing.BillingService`
+
+Single billing module — not a polymorphic provider abstraction.
+
+```python
+class BillingService:
+    @staticmethod
+    async def start_trial(db, account: Account) -> Subscription:
+        """Creates or updates the Subscription row for a new account.
+        Sets plan='pro', status='trialing', current_period_end=now()+14d.
+        Called from /auth/register (email path) and OAuth-callback flows.
+        No Stripe API call yet — Stripe Customer is created lazily at first
+        checkout."""
+
+    @staticmethod
+    async def create_checkout_session(db, account, plan, seats, billing_interval) -> str:
+        """Returns the Stripe Checkout URL. Creates Stripe Customer if missing
+        (stores stripe_customer_id on the **Account** row — existing column at
+        accounts.stripe_customer_id), then builds checkout.sessions.create
+        with line_items, mode='subscription', subscription_data.trial_end if
+        still within local trial, success/cancel URLs. Subscription row is
+        updated by the webhook handler with stripe_subscription_id and
+        stripe_price_id once checkout completes."""
+
+    @staticmethod
+    async def apply_subscription_event(db, event_type: str, payload: dict) -> None:
+        """Single entry point for every Stripe webhook that mutates subscription
+        state. Pure function of (event_type, payload) -> DB writes. Called from
+        the webhook handler after signature verification + idempotency check."""
+
+    @staticmethod
+    async def open_customer_portal(account) -> str:
+        """Returns Stripe-hosted Customer Portal URL for card updates and
+        cancellation."""
+
+    @staticmethod
+    async def get_billing_state(db, account: Account) -> BillingStateResponse:
+        """Returns the full billing snapshot for /billing/state — subscription
+        status, plan, plan_billing metadata, plan_limits values, and the
+        flattened effective feature flags (defaults overridden by
+        account_feature_overrides)."""
+```
+
+`account_id` is the canonical local key; Stripe is the canonical remote state; the webhook handler is the bridge.
+
+### Replacing the trial auto-downgrade
+
+The existing logic in `deps.py:81-129` mutates `subscriptions` on every request when a trial expires:
+
+```python
+# CURRENT (to be removed):
+if subscription.status == "trialing" and subscription.current_period_end < now():
+    subscription.plan = "free"
+    subscription.status = "active"
+    subscription.current_period_end = None
+    subscription.current_period_start = None
+    await db.commit()
+```
+
+**Replace this entire block with no-op.** Trial expiry becomes a *computed* state. The data stays as `status='trialing'`, `current_period_end` in the past — readable, observable, idempotent. The new `require_active_subscription` dep enforces the lockout.
+
+If we ever want an explicit `'expired'` status (for analytics observability), it can be added later without changing the semantic of "trialing + past current_period_end = locked."
+
+### New backend dep — `require_active_subscription`
+
+```python
+_SUBSCRIPTION_GUARD_ALLOWLIST = {
+    # auth & profile
+    "/api/v1/auth/me",

+) -> Subscription:
+    """Enforces 'this account currently has access.' Mounted on routers that

+            },
+        )
+
+    return sub
+```
+
+Mounted on every router under `/api/v1/` *except* the explicit allowlist. GET endpoints for past sessions/trees during the 30-day read-only post-expiry window need a softer variant — see Section 3 step 6 for the read-only contract. Implementation plan will identify each protected endpoint specifically.
+
+### New backend dep — `require_verified_email_after_grace`
+
+Mirror of `require_active_subscription`, but for email verification. The frontend `<EmailVerificationWall />` is a UX layer; this dep is the security layer that prevents an unverified user from bypassing the wall by hitting product APIs directly.
+
+```python
+_EMAIL_VERIFICATION_ALLOWLIST = {
+    # auth & session
+    "/api/v1/auth/me",
+    "/api/v1/auth/logout",
+    "/api/v1/auth/email/send-verification",
+    "/api/v1/auth/email/verify",
+    "/api/v1/auth/password/change",
+    # users own profile
+    "/api/v1/users/me",
+    # billing — let user manage subscription even if email unverified
+    "/api/v1/billing/state",
+    "/api/v1/billing/checkout-session",
+    "/api/v1/billing/portal-session",
+}
+
+VERIFICATION_GRACE_DAYS = 7
+
+async def require_verified_email_after_grace(
+    request: Request,
+    current_user: User = Depends(get_current_active_user),
+) -> None:
+    """Enforces 'this user has verified their email, OR is still inside the
+    7-day grace from account creation.' OAuth signups bypass cleanly because
+    /auth/google/callback and /auth/microsoft/callback set
+    users.email_verified_at = now() (provider-attested).
+    Mounted on every protected router *except* the explicit allowlist."""
+
+    if request.url.path in _EMAIL_VERIFICATION_ALLOWLIST:
+        return
+
+    if current_user.email_verified_at is not None:
+        return
+
+    grace_ends = current_user.created_at + timedelta(days=VERIFICATION_GRACE_DAYS)
+    if datetime.now(timezone.utc) < grace_ends:
+        return  # still inside grace
+
+    raise HTTPException(
+        status_code=403,
+        detail={
+            "error": "email_not_verified",
+            "grace_ended_at": grace_ends.isoformat(),
+            "resend_url": "/api/v1/auth/email/send-verification",
+        },
+    )
+```
+
+Differs from `require_active_subscription` in three ways:
+
+- **403 (Forbidden) rather than 402 (Payment Required)** — verification is identity, not billing. Lets the frontend interceptor route to a verification CTA, distinct from the upgrade CTA.
+- **No DB read** — uses fields already on the `current_user` row from `get_current_active_user`. Cheap.
+- **Allowlist includes `/billing/*`** — an unverified user past day 7 should still be able to convert to paid (verification gates feature use, not billing). The verification banner persists into Checkout if needed.
+
+The two guards compose: most routers depend on **both** `require_active_subscription` AND `require_verified_email_after_grace`. The implementation plan will identify each protected router specifically; both guards are non-optional for product surfaces.
+
+### Stripe webhook handler — `POST /api/v1/webhooks/stripe`
+
+A stub already exists at `app/api/endpoints/webhooks.py` with signature verification + an early-out when `settings.stripe_enabled=False`. This work extends the stub — does not replace it — by wiring concrete event handlers, idempotency tracking, and `BillingService.apply_subscription_event` integration.
+
+- Public endpoint; signature verification is the only gate.
+- Reads `Stripe-Signature` header → `stripe.Webhook.construct_event(payload, sig, STRIPE_WEBHOOK_SECRET)` → 400 on mismatch.
+- **Idempotency**: every event recorded in `stripe_events` keyed by Stripe's event id. If the row exists, return 200 immediately.
+- Uses `_admin_session_factory()` — no `current_account_id` is set during webhook processing (Phase 4 RLS pattern).
+- **Replay protection**: Stripe signatures embed a timestamp; reject if older than 5 min.
+
+Events handled:
+
+| Event | Action |
+|---|---|
+| `checkout.session.completed` | Activate: `subscriptions.status='active'`, set `subscriptions.stripe_subscription_id`, `subscriptions.stripe_price_id`, `subscriptions.current_period_start/end`, `subscriptions.seat_limit` from session line_items. (`accounts.stripe_customer_id` was set earlier at `create_checkout_session` time.) |
+| `customer.subscription.updated` | Reflect plan changes / period transitions / seat updates |
+| `customer.subscription.deleted` | `status='canceled'`, lock via `require_active_subscription` |
+| `invoice.payment_failed` | `status='past_due'` |
+| `invoice.payment_succeeded` | Confirm `status='active'` after dunning recovery |
+| Other | Log and ack 200 |
+
+### Backend feature-gate dep — `require_feature`
+
+Reads from the existing 3-table chain (no new tables). **`require_feature` internally composes with `require_active_subscription`** — feature gating without subscription gating would let canceled/expired-trial accounts pass feature checks. They are not independent.
+
+```python
+async def require_feature(flag_key: str):
+    async def _dep(
+        sub: Subscription = Depends(require_active_subscription),
+        user: User = Depends(get_current_active_user),
+        db: AsyncSession = Depends(get_admin_db),
+    ) -> None:
+        # require_active_subscription has already verified the account is live;
+        # sub is the live Subscription row. Now check the feature flag.
+        flag = await _resolve_flag(db, user.account_id, sub.plan, flag_key)
+        if not flag.enabled:
+            raise HTTPException(
+                status_code=402,
+                detail={
+                    "error": "feature_not_in_plan",
+                    "feature": flag_key,
+                    "current_plan": sub.plan,
+                    "upgrade_url": "/account/billing/select-plan",
+                },
+            )
+    return _dep
+
+
+async def _resolve_flag(db, account_id, plan_key, flag_key):
+    """Resolve effective feature flag value:
+    1. account_feature_overrides for (account_id, flag_key) -> if exists, use that
+    2. else plan_feature_defaults for (plan, flag_key) -> use that
+    3. else default disabled
+    """
+```
+
+Used as `Depends(require_feature("psa_integration"))` on PSA endpoints, Escalation Mode, Script Builder, Analytics endpoints. The 402-with-payload pattern lets the frontend route the user to `/account/billing/select-plan`.
+
+For quantitative limits (sessions per month, AI builds): existing `plan_limits` columns (`max_sessions_per_month`, `max_ai_builds_per_month`, etc.) already cover these. Use a sibling helper:
+
+```python
+async def require_within_limit(field: str):
+    """e.g., field='max_sessions_per_month' — checks current usage against
+    the resolved plan_limits value, with account-override consulting via
+    /admin/plan-limits/account-overrides table."""
+```
+
+This is closer to the existing `get_user_plan_limits` helper (`core/subscriptions.py`) and reuses that path.
+
+### Caching strategy
+
+- Subscription row, plan_limits row, plan_billing row, and resolved feature flag map: cached in `app.state.billing_cache` keyed by `account_id`. TTL 5 minutes.
+- Explicit invalidation triggers:
+  - Stripe webhook handler when `subscriptions` state changes (account-keyed invalidation).
+  - `/admin/plan-limits` PUT (invalidate **all** accounts on that plan, since plan-wide limits / billing fields changed).

+  },
+  enabled_features: Record<string, boolean>,  -- flat resolved map
+}
+```
+
+Frontend hooks:
+
+- `useFeature(key: string): boolean` — reads `enabled_features[key]` from `useBillingStore`.
+- `useFeatureLimit(key): { used, limit, percentage, isAtLimit }` — combines `plan_limits[key]` with a lazy `/usage/{key}` count.
+- `useTrialBanner(): { stage: 'pristine' | 'warning' | 'urgent' | 'expired', daysRemaining }` — derived from `subscription.status` + `current_period_end`.
+- `<FeatureGate feature="psa_integration" fallback={<UpgradePrompt />}>...children</FeatureGate>` — wrapper for whole-section gating.
+
+`useBillingStore` is a Zustand store with:
+- Initial fetch on auth-store login.
+- Refetch on webhook-driven server-sent events (or, for v1, polling every 60s while the dashboard is mounted).
+- Manual `refetchBilling()` exposed for use after Stripe Checkout success-redirect.
+
+`/auth/me` and `UserResponse` stay user-focused — no billing data embedded.
+
+### Admin UI — reuse existing surfaces
+
+- `/admin/plan-limits` — extended to also surface `plan_billing` fields in the editor (single PUT round-trips both tables in one transaction).
+- `/admin/feature-flags` — unchanged. Toggling a flag's `plan_feature_defaults` enables/disables the feature for that plan tier.
+- `/admin/feature-flags/account-overrides` — unchanged. Used for sales-negotiated grants, comp accounts, kill-switching a feature for one customer.
+
+No new combined `/admin/plans` admin page in v1.
+
+### Failure modes
+
+| Scenario | Outcome |
+|---|---|
+| User abandons Stripe Checkout | No webhook fires; `subscriptions.status` stays `trialing`; trial-end wall fires normally on day 14 via `require_active_subscription` |
+| Webhook arrives before app reconciles local state | `stripe_events` idempotency makes this safe |
+| Webhook secret rotated | Old webhook attempts 400 until env var redeployed |
+| Concurrent webhooks for the same subscription | DB row-level locks on the `subscriptions` row serialize updates; idempotency check is the first read in the transaction |
+| Stripe outage during checkout | `BillingService.create_checkout_session` raises; frontend shows "Couldn't start checkout — try again" toast |
+| Account on `complimentary` accidentally hits a webhook (e.g., admin manually attached a Stripe customer) | Handler transitions to whatever Stripe says; admin can revert via DB or via `/admin/plan-limits/account-overrides` if needed |
+| OAuth-only user attempts `/auth/login` (password) | Login endpoint rejects with 400 `{"error": "use_oauth_provider", "providers": ["google"]}` so frontend can route them to the right button |
+| OAuth-only user attempts `/auth/password/change` | Endpoint rejects with 400 — must set initial password via a separate `/auth/password/set-initial` flow (out of scope for v1; OAuth users stay OAuth-only) |
+| OAuth-only user requests password reset | Reset email is suppressed; user is shown "Sign in with {provider}" instead |

+
+## Section 5 — Migration plan
+
+### Pre-deploy: Stripe configuration
+
+Manual setup, separate per environment.
+
+**Status note (2026-05-05):** Stripe **test mode** Products + Prices + webhook endpoint + test env vars in Railway are already configured. Live-mode setup remains for cutover.
+
+For each environment:
+
+1. **Stripe Dashboard**:
+   - Create Products: `ResolutionFlow Starter`, `ResolutionFlow Pro`, `ResolutionFlow Enterprise` (no public price).
+   - Create Prices for Starter/Pro: monthly + annual recurring.
+   - Enable **Customer Portal** with: update payment method, cancel subscription, view invoices. Disable plan-switching from the portal.
+   - Register webhook endpoint at `https://api.resolutionflow.com/api/v1/webhooks/stripe` with the events listed in Section 4. Save the signing secret.
+2. **Railway env vars** (per environment):
+   - `STRIPE_SECRET_KEY`, `STRIPE_WEBHOOK_SECRET`, `STRIPE_PUBLISHABLE_KEY` (frontend; needs `ARG`+`ENV` in `frontend/Dockerfile` per Lesson 60).
+
+### Schema migration
+
+Manual revisions per Lesson 77. New chain branches from the most recent of `main`'s heads (`070`, `c0f3a4b7e91d`, `024`) and merges via `alembic upgrade heads`. Migration filenames are listed in Section 2.
+
+Forward-only.
+
+### Pilot user transition
+
+- Migration step 8 sets `subscriptions.status='complimentary'`, `plan='pro'` for all existing accounts (≤ 100 rows). Single statement.
+- **Outbound communication**: a single email from `EmailService.send_complimentary_account_announcement` to every pilot user 1-2 days before cutover:
+  > *"We're opening ResolutionFlow up for new signups. Your account is now a Complimentary Pro account — nothing changes for you. You'll see a small "Complimentary Pro" tag in the app instead of any trial pill. Thanks for piloting."*
+- **In-app first-login toast** (optional; ship without if scope tightens): per-browser via localStorage key `rf-complimentary-announcement-seen-{user_id}`.
+
+### Existing invite-code disposition
+
+- `invite_codes` table preserved.
+- `User.invite_code_id` foreign keys preserved for historical pilots.
+- Registration handler (`/auth/register`) drops the invite_code-required gate. The `UserCreate.invite_code` field stays in the schema for backward compatibility but is ignored at registration. No new validations against the `invite_codes` table at signup.
+- No promo-code repurposing. Invite codes simply stop being consumed.
+
+### Beta-signup deprecation
+
+- `beta_signup.py` endpoint stays mounted but returns 307 redirect to `/register?from=beta`.
+- Existing waitlist rows: send a "we've launched — come on in" email with a one-time `from=beta` link. Preserve the table; do not drop.
+
+### Deploy ordering — dark launch then cutover
+
+1. **Backend deploy with `SELF_SERVE_ENABLED=false`**: all new endpoints exist (webhook handler, billing, OAuth callbacks, sales-leads, bulk invite, billing/state). `/auth/register` retains the existing invite-code requirement. `/pricing` returns 404. Webhook handler is **live**.
+2. **Frontend deploy with `VITE_SELF_SERVE_ENABLED=false`**: new surfaces are routed but hidden behind the flag.
+3. **Stripe live-mode configuration in prod** (manual, ~30 min).
+4. **Internal validation (1-2 days)**: founder + any teammates use a per-email allowlist to enable self-serve for their accounts only. Tests cover: email signup, OAuth signup paths, invitation accept (with email-match enforcement), pilot complimentary view, past-due simulation via Stripe test cards, subscription guard for locked accounts.
+5. **Cutover**: flip `SELF_SERVE_ENABLED=true` and `VITE_SELF_SERVE_ENABLED=true` in prod. Pricing page goes live.
+6. **Week 1 monitoring**: PostHog funnel; webhook logs; error rates.
+
+### Rollback strategy
+
+- Schema is forward-only — no down-migration for the backfills.
+- Rollback = flag flip. `SELF_SERVE_ENABLED=false` reverts public surfaces; pilot users continue on `complimentary` status (benign — the existing schema supports it either way after step 8).
+- New surfaces (pricing page, etc.) return 404 when the flag is off.
+- Webhook handler stays live regardless.
+
+### Risks worth flagging
+
+| Risk | Mitigation |
+|---|---|
+| Pilot users confused by "Complimentary Pro" change | Pre-launch email + first-login toast |
+| `is_paid` regression — paid metrics include comp accounts pre-fix | Audit `Subscription.is_paid` callers as part of step 1 of implementation; fix in same PR |
+| Webhook misfires producing wrong subscription state | Idempotency table + alerting + Stripe webhook replay |
+| Multi-head Alembic merge breaks in CI | Test `alembic upgrade heads` (plural) on a fresh DB before merging |
+| Stripe Test vs. Live mode confusion | Distinct env vars per env; first prod transaction verified manually |
+| OAuth callback `redirect_uri` drift across envs | Single `OAUTH_REDIRECT_BASE` env var; tested per env in validation |
+| Email deliverability for verification + invitations + sales leads | Reuse existing `EmailService` pipeline; verify SPF/DKIM/DMARC alignment |
+| Email-match enforcement at register breaks teammate accept if invitee mistypes their address | Clear error message; resend with corrected email is one click from the failure page |
+| Subscription guard allowlist drift (a new endpoint added without thinking about lockout) | Add a CI test that exercises every router with a `canceled` subscription and verifies 402 unless explicitly allowlisted |
+| Email-verification guard allowlist drift (a new endpoint added without thinking about unverified users past grace) | Same CI pattern — exercise every router with an unverified day-8 user and verify 403 unless explicitly allowlisted |
+| Plan key rename (`free`/`pro`/`team` → `starter`/`pro`/`enterprise`) | Decision deferred to implementation plan; if rename, migration must update every reference in `subscriptions.plan` and `plan_limits.plan` |
+
+---
+
+## Section 6 — Testing, rollout, open risks
+
+### Test strategy
+
+#### Backend (`pytest`)
+
+- **Unit tests** for `BillingService` methods. Stripe mocked via `respx`. Each method's happy path + at least one error path.
+- **Webhook handler integration tests**: feed canned Stripe webhook payloads and assert resulting `subscriptions` state. One test per event type. **Idempotency test**: send the same event id twice, assert single state mutation.
+- **`require_feature` integration tests**: parametrized over (plan, flag_key) pairs; test override resolution (`account_feature_overrides` beats `plan_feature_defaults`).
+- **`require_active_subscription` integration tests**:
+  - Each `subscriptions.status` value × allowlisted/non-allowlisted route → expected 200 or 402.
+  - **Replaces and verifies the trial expiry change**: a `trialing` row with `current_period_end < now()` should NOT be mutated by the dep; the dep should return 402 on protected routes and 200 on allowlisted routes.
+  - "complimentary should not block protected routes" smoke test.
+- **`require_verified_email_after_grace` integration tests**:
+  - Each combination of (verified, unverified-in-grace, unverified-past-grace) × (allowlisted, non-allowlisted route) → expected 200 or 403.
+  - OAuth-signup user has `email_verified_at` set at callback time → never blocked.
+  - User on day 6 unverified passes; user on day 8 unverified blocks; verifying mid-test transitions to passing.
+- **Combined-guard test**: protected routers mounting both `require_active_subscription` and `require_verified_email_after_grace` reject an unverified expired-trial account with the appropriate error (whichever check fires first is acceptable; assert one of the two error payloads).
+- **Subscription model property tests**: `is_active`, `is_paid`, `has_pro_entitlement` across every status × plan combination.
+- **Auth integration tests**:
+  - `/auth/register` happy path + duplicate email + weak password + email-match enforcement when `account_invite_code` provided.
+  - `/auth/google/callback` and `/auth/microsoft/callback` with mocked OAuth provider responses.
+  - `/auth/email/send-verification` auto-fired by register.
+  - `/auth/email/verify` with valid / expired / already-used tokens (already covered; smoke regression).
+  - **OAuth-only user paths**: `/auth/login` rejects, `/auth/password/change` rejects, password reset suppressed.
+- **Invitation tests**:
+  - `/accounts/me/invites` create now sends email (regression: today it doesn't).
+  - `/accounts/me/invites/bulk` creates N rows + sends N emails.
+  - Email-match enforcement at register.
+  - Expired/revoked token, idempotent re-accept.
+- **Plan-limits + feature-flags admin tests**: existing tests stay; extend with a test that round-trips `plan_billing` fields through `/admin/plan-limits` PUT.
+- **Anti-parrot guardrail**: existing `tests/test_prompt_anti_parrot.py` covers any new system prompts (verification email, invitation email, sales-lead intake) automatically.
+- **Phase 4 RLS smoke test**: every new account-scoped endpoint exercised with a non-matching `app.current_account_id`.
+
+#### Frontend (Vitest + Playwright)
+
+- **Component tests** for `<TrialPill />` (each subscription status branch + trialing-expired computed branch), `<NextStepCard />`, `<EmailVerificationBanner />`, `<EmailVerificationWall />`, `<TrialEndedWall />`, `<FeatureGate />`, `<UpgradePrompt />`.
+- **Hook tests** for `useFeature`, `useFeatureLimit`, `useTrialBanner`, `useBillingStore` (initial fetch, refetch on webhook event, refetch after Stripe Checkout success).
+- **Playwright E2E**:
+  - Register → wizard step-by-step → dashboard.
+  - OAuth round-trip with mocked provider.
+  - Trial-end wall → plan picker → mock Stripe Checkout → activated state.
+  - Past-due banner via webhook simulation.
+  - Pilot complimentary view (no walls, no nudges, "Complimentary Pro" pill).
+  - Invitation accept (full flow with `account_invite_code` from a backend fixture; email-match success and failure paths).
+
+#### Manual validation phase (1-2 days before cutover)
+
+| Scenario | Method |
+|---|---|
+| Email signup → wizard → first session → trial-end synthetic time → Checkout → active | Real flow with Stripe test mode + a date-shimmed account |
+| Google sign-in | Real Google account |
+| Microsoft sign-in | Real Microsoft 365 account |
+| Past-due simulation | Stripe test card `4000 0000 0000 0341` |
+| Pilot complimentary banner + first-login toast | Log in as an existing pilot account post-deploy |
+| Webhook signature mismatch handling | Send a forged webhook with bad signature, expect 400 + log entry |
+| OAuth provider redirect_uri matches | Visual check on each environment's Google + Microsoft app config |
+| `is_paid` audit | Query a known complimentary account: confirm `is_paid=False`, `has_pro_entitlement=True` |
+
+### Rollout monitoring
+
+#### PostHog event taxonomy
+
+- **Funnel**: `pricing_page_viewed`, `register_started`, `register_completed` (with `method`), `email_verification_sent`, `email_verification_completed`.
+- **Wizard**: `welcome_wizard_step_completed` (step number), `welcome_wizard_skipped` (`from_step`), `welcome_wizard_completed`.
+- **Activation**: `first_session_started` (existing), `psa_connected`, `teammate_invited`, `teammate_accepted_invite`.
+- **Trial conversion**: `trial_modal_shown`, `trial_modal_dismissed`, `trial_ended_wall_shown`, `plan_picker_viewed`, `checkout_session_created`, `checkout_completed`, `checkout_abandoned`.
+- **Feature-gate signal**: `feature_gate_blocked` (with `feature_key` + `current_plan`).
+- **Sales**: `talk_to_sales_form_submitted` (with `source`), `complimentary_account_first_view`.
+
+#### Alerting
+
+- Stripe webhook signature failures > 1/hour.
+- Stripe API errors during checkout-session creation > 1/hour.
+- OAuth callback failures > 5/hour.
+- Email send failures (`EmailService` errors) on verification or invitation paths.
+- Any 500 from `/webhooks/stripe`.
+- 402 rate spike on non-allowlisted endpoints (could indicate guard misconfiguration).
+
+#### Operational dashboards
+
+- Daily: trial signups, completed checkouts, MRR delta (using corrected `is_paid`).
+- Weekly: trial→paid conversion rate, OAuth-method mix, wizard skip rate per step.
+- Per-feature: `feature_gate_blocked` count by `flag_key`.
+
+### Stripe MCP tooling note
+
+Once the Stripe MCP plugin loads in a future Claude Code session, it speeds up two things: **debugging webhook state** for support cases and **ad-hoc subscription mutations** (compt'ing accounts, fixing stuck states). Worth using post-launch for ad-hoc support; not load-bearing for the spec.
+
+### Open risks and unknowns (carry-forward)
+
+| # | Item | Status |
+|---|---|---|
+| 1 | **Pricing numbers** ($/seat/month for Starter and Pro) | Out of design scope. Set during validation phase. Schema supports any value via `plan_billing.monthly_price_cents` / `annual_price_cents`. |
+| 2 | **Stripe Tax** | Disabled in v1. Revisit when first international signup arrives. |
+| 3 | **Multi-account membership** (one user in multiple shops) | Out of scope. v1 is one user → one account. |
+| 4 | **Owner transfer** | **Existing capability** — `POST /accounts/me/transfer-ownership` (`accounts.py:150`). Surface in the redesigned Account → Team page. |
+| 5 | **Annual billing UI** | Stripe Prices exist via `plan_billing.stripe_annual_price_id`, but the in-app picker only surfaces monthly in v1. Add later. |
+| 6 | **SSO (SAML/OIDC) for Enterprise** | Promised on the pricing page Enterprise tier. Actual impl deferred until first paying Enterprise customer. Sales conversation must set expectations honestly. |
+| 7 | **GDPR DPA template** | Trust strip claims "GDPR-ready DPA available." Founder/lawyer needs to produce the actual document — not eng work, but blocking the trust-strip claim being honest. |
+| 7b | **SOC2 status** | Trust strip claims "SOC2 in progress." If the engagement isn't started by cutover, soften the trust-strip copy. |
+| 8 | **Customer Portal cancellation customization** | Stripe-hosted Portal can't be customized. Acceptable for v1. |
+| 9 | **Email deliverability** | First big surge may trip spam filters. Verify SPF/DKIM/DMARC alignment before cutover. |
+| 10 | **Reverse-trial conversion math** | If trial→paid is bad post-launch, may need to flip to card-upfront. Schema supports it; policy decision based on data. Re-evaluate at week 4. |
+| 11 | **Promo codes** | **Deferred from v1.** No `promo_codes` table. If a launch campaign needs them, add a separate table later with Stripe coupon semantics; do not retrofit `invite_codes`. |
+| 12 | **Pricing page A/B testing** | Not in v1. PostHog has experiment tooling for A/B headlines later. |
+| 13 | **OAuth-only password set-initial flow** | An OAuth-only user can't add a password later in v1. Out of scope; users who want a password can ask support to enable it manually. |
+| 14 | **Plan key rename** | Existing `plan_limits` rows use `'free' / 'pro' / 'team'`. Public-facing tiers are Starter / Pro / Enterprise. Implementation plan decides whether to rename keys or maintain a display-name mapping in `plan_billing`. |

+
+## Appendix B — Glossary
+
+- **Reverse trial**: time-bounded full-access trial with no card required at signup; card requested before billing kicks in.
+- **Sales-assist (E)**: dedicated path for Enterprise prospects via "Talk to sales" CTA → contact form → manual onboarding by founder/sales.
+- **Wedge**: Escalation Mode — the magic-moment feature pilots are evaluated against (≥1.0 hour saved per week per pilot per kill-switch criteria).
+- **Complimentary**: permanent, non-time-bounded `subscriptions.status='complimentary'` value for grandfathered pilot users. No nags, no walls, full Pro entitlement. Distinct from `trialing` in that it never expires; distinct from `active` in that it doesn't count toward paid/MRR metrics.
+- **Has Pro entitlement**: a property derived from `(status, plan, current_period_end)` that answers "can this account access Pro features right now?" — true for paid Pro, complimentary Pro, and active trials. Used by `require_feature` and `require_active_subscription`.
+- **Locked subscription**: computed state `(status='trialing' AND current_period_end < now())` OR `(status IN ('canceled', 'incomplete'))`. No mutation occurs; `require_active_subscription` raises 402 on protected routes.
+- **Plan keys**: `plan_limits.plan` is the canonical key; `plan_billing` joins on it; `subscriptions.plan` is the per-account key. Public-facing tier names (Starter / Pro / Enterprise) are display labels via `plan_billing.display_name`.
