-## PR Workflow With Codex Review
-
-PR review is run automatically by `openai/codex-action` in CI
-(`.github/workflows/codex-review.yml`). On every PR push, the action
-checks out the merge ref, runs Codex against the diff, and posts the
-verdict as a PR comment.
+3. **Merge only when CI and Ollama AI review pass and GitHub reports mergeable** (see next section).
 
-Prereq: the `OPENAI_API_KEY` repo secret must be set. Without it the
-precondition job emits a warning and skips review; the rest of CI
-still runs.
+## AI PR Review
 
-If you need to re-run a review (e.g., after fixing a finding), just
-push another commit — the workflow's concurrency group cancels the
-prior run and starts a fresh review on the new head.
+Run AI review through `.github/workflows/codex-review.yml` using Ollama Cloud,
+not `openai/codex-action`. Default to `glm-5.3-flash` at
+`https://ollama.com/api/chat`; configure `OLLAMA_API_KEY` as a GitHub Actions
+secret. Override the model or full chat endpoint with repository variables
+`OLLAMA_MODEL` and `OLLAMA_ENDPOINT`. See [setup and limits](docs/ai-pr-review.md).
 
-For local iteration before pushing, the legacy
-`openai/codex-plugin-cc` plugin still works:
+Require a successful `codex-pr-review-gate` result for the current PR head/base.
+Treat missing credentials, missing/binary/truncated patches, stale commits,
+provider errors, malformed responses, and blocking findings as failed review.
+Do not self-approve or treat a skipped review as approval.
 
-```
-git fetch origin main
-/codex:review --base origin/main
-```
+Builder agents may merge only after CI and AI review pass, GitHub reports the
+PR mergeable, and all required reviews/comments/conflicts are resolved.
+Reviewer agents must not merge. Keep a blocked PR open and fix or report the
+blocker; do not bypass checks or close the PR as a substitute for merging.
 
-Use it when you want a verdict without opening a PR, or when CI is
-unavailable. For routine PR review, lean on the CI action — it runs
-without anyone having to remember.
-
-Do not self-approve by posting `LGTM` markers.
-Do not require or wait for the old GitHub `codex-pr-review-gate` check.
-
-A PR may merge only when:
-1. CI is green.
-2. GitHub says the PR is mergeable.
-3. Codex local review reports no blocking issues.
-4. There are no unresolved review comments or merge conflicts.
-
-If Codex review reports blockers:
-1. Keep the PR open.
-2. Fix the issues.
-3. Run relevant local checks.
-4. Push a follow-up commit.
-5. Run Codex review again.
-
-If the PR has merge conflicts:
-1. Update the branch against the latest base branch.
-2. Resolve conflicts carefully.
-3. Run relevant local checks.
-4. Push the resolution.
-5. Run Codex review again.
-
-If CI passes and Codex review passes:
-- Merge the PR using the repository's normal merge method.
-- Do not manually close the PR as the success path.
-
-If GitHub blocks the merge:
-- Report the exact blocker.
-- Leave the PR open.
-
-Only close without merging if the work is abandoned, duplicated, or superseded,
-and leave a PR comment explaining why.
+Do not enable a required check in GitHub protection until its workflow has
+landed on the default branch and the check has appeared on a PR. Branch
+protection/ruleset configuration remains a separate administrative step.

+# Ollama PR Review
+
+The PR reviewer uses Ollama Cloud directly. The scheduling solver remains a
+local greedy heuristic; this change does not add an LLM to application routes.
+
+## Configuration
+
+| GitHub Actions setting | Kind | Default |
+| --- | --- | --- |
+| `OLLAMA_API_KEY` | Secret | Required; no fallback to an OpenAI key |
+| `OLLAMA_ENDPOINT` | Repository variable | `https://ollama.com/api/chat` |
+| `OLLAMA_MODEL` | Repository variable | `glm-5.3-flash` |
+
+Set the secret using GitHub's secret UI or `gh secret set OLLAMA_API_KEY`, which
+prompts for the value. Never put the key in source, a PR, chat, or a command-line
+argument. Repository `.env` files do not configure GitHub-hosted runners.
+
+Use the full native chat URL, not an OpenAI-compatible `/v1` URL. Endpoints must
+use HTTPS with no embedded credentials, query, or fragment. Redirects are
+rejected. Only point the endpoint at an approved provider: it receives PR
+metadata and patches, and the bearer key. Model names are configurable, but
+there is no automatic fallback to a different model or provider.
+
+Ollama's [cloud API documentation](https://docs.ollama.com/cloud) describes
+direct bearer-key access. Its public `/api/tags` catalog lists `glm-5.3-flash`;
+the [model library](https://ollama.com/library/glm-5.3-flash) uses the separate
+`:cloud` tag for requests proxied through a local Ollama installation.
+
+## Review Behavior
+
+- Run `.github/workflows/codex-review.yml` on PR open, push, reopen, and ready-for-review.
+- Keep the stable check name `codex-pr-review-gate` for future GitHub enforcement.
+- Fetch metadata and patches through GitHub's API. Never check out or execute PR code in the credential-bearing job.
+- Bind results to the event's head and base SHAs; recheck before and after publishing feedback.
+- Send only bounded diff context to the model. This is a diff-only reviewer, not a repository-exploring agent.
+- Ask for JSON and validate it locally. Ollama Cloud currently does not support [structured output enforcement](https://docs.ollama.com/capabilities/structured-outputs), so no `format` parameter is sent.
+- Post validated feedback as inert JSON text, not a GitHub approval. P0/P1 findings fail even if the model claims a safe verdict.
+- Fail on missing credentials, provider errors, timeouts, incomplete output, malformed reports, stale commits, or unsuccessful feedback publication. Never silently skip review or convert an error to success.
+
+Limit requests to 400,000 UTF-8 bytes of PR metadata/patches and 480 seconds.
+Read Ollama's newline-delimited JSON stream within a 10-minute job limit.
+Bound the response stream to 2,000,000 bytes and final-answer content to 30,000
+characters. Discard reasoning text without logging it; require a complete stream
+ending in `done: true` with `done_reason: stop` before validating the report.
+Streaming allows long reasoning-model responses without waiting for a single
+buffered response under the former two-minute deadline. Keep the requested
+model and its default reasoning behavior; do not substitute a model to pass review.
+Fail on missing patches (including binary-only changes), patch line-count
+mismatches, and incomplete GitHub file listings. Split oversized PRs or obtain
+independent review through the repository's approved process; do not bypass a
+required check. External-fork and Dependabot PRs cannot normally access this
+secret and will fail closed. Do not use a privileged fork trigger to execute
+their code. A dedicated trusted-review service remains a future option.
+
+An LLM verdict is fallible and does not prove production readiness. Keep CI,
+human review where required, and GitHub mergeability as separate requirements.
+Reviewer agents must never merge. Builder agents must not bypass protection.
+
+## Request Diagnostics
+
+Failed HTTP requests report the numeric status with fixed troubleshooting guidance.
+Check the API key for 401, account/model access for 403, endpoint/model configuration
+for 404, and quota/rate limits for 429. Server errors suggest checking the provider
+service. These are troubleshooting hints, not a diagnosis of the provider's cause.
+Network/timeout failures before a response do not report an HTTP status.
+Log the HTTP status when response headers arrive. Report expiration of the
+480-second request deadline separately from HTTP authentication failures.
+Never log provider response bodies, status text, headers, or transport exception
+messages. Correct the configuration or provider issue and rerun the failed job;
+do not bypass the review gate.
+
+## Rollout And Validation
+
+1. Add the workflow conversion in a PR and configure the Ollama secret separately.
+2. Review and merge the workflow normally, retaining existing required CI checks.
+3. Confirm the check appears and exercises pass/fail paths on a PR.
+4. Only then require `codex-pr-review-gate` in branch protection or rulesets.
+
+This conversion does not change GitHub settings, auto-merge, or branch protection.
+Workflow-file changes themselves require trusted review: a PR able to edit its
+own workflow can alter a check's logic, so a status name alone is not a tamper-proof gate.
+
+Run `poetry run pytest tests/unit/test_ollama_review_workflow.py` with Node.js
+20+ installed. Tests execute the actual inline workflow JavaScript with mocked
+GitHub/Ollama calls, including failure cases; no live AI key or inference is used.
+Run `make test-unit-fast` while iterating and `make test-all` before pushing.
+Verify live provider access and GitHub checks separately before claiming setup complete.

 # Password Reset Feature - BDD Scenarios
 
+## Current Web Delivery Contract
+
+Run the SignUpFlow web app at `FRONTEND_URL` (or `APP_URL` when unset); use the
+public HTTPS origin in production. `POST /auth/forgot` attaches its email task
+to the HTML response. Reset emails contain `/auth/reset/{token}` browser links
+and retain the `signupflow:///reset-password?token=...` mobile deep link.
+The API endpoints are `POST /api/v1/auth/forgot-password` and
+`POST /api/v1/auth/reset-password`; older scenario endpoint names below are historical.
+
+Keep `DEBUG_RETURN_RESET_TOKEN` off in production. Return the same generic
+message for known and unknown accounts. Log failed sends without including
+email addresses or reset tokens; request a fresh link to retry delivery, which
+invalidates the previous token. Background tasks are best-effort, not a durable
+queue. Track durable delivery and staging-provider verification in #266 and #262.
+
+Run `poetry run pytest tests/web/test_password_reset.py tests/api/test_password_reset_email.py`
+to verify captured email links, one-time use, token rotation, and send failures
+without external email delivery.
+
 ## Feature Overview
 Users can reset their password if they forget it by receiving a secure reset link via email. The reset token expires after 1 hour for security.

+# Operational acceptance playbooks
+
+Run these before calling a church or basketball scheduling release ready:
+
+- [Church: six-week ministry roster](church.md)
+- [Basketball: six-week team roster](basketball.md)
+- [Executed acceptance results and limitations](validation.md)
+
+These are scheduling acceptance exercises, not certification that a real organization
+is operationally ready. Use fictional people and a disposable database. Never run
+the fixtures against a customer organization. Email and SMS must remain disabled.
+
+## Reproduce
+
+From the repository root, after installing the development dependencies:
+
+```bash
+EMAIL_ENABLED=false SMS_ENABLED=false poetry run pytest tests/api/test_domain_playbooks.py -v
+poetry run pytest tests/unit/test_solver_role_slots.py -v
+poetry run playwright install chromium
+EMAIL_ENABLED=false SMS_ENABLED=false poetry run pytest tests/e2e/test_domain_playbooks.py -v
+make test-unit-fast
+make test-all
+```
+
+The API tier uses real JWT identities and an isolated in-memory SQLite database.
+The browser tier starts the real application against a temporary SQLite database.
+It uses API setup for the bulk roster and five repeated weeks, then browser login,
+multi-role event creation, solve, review, publish, and member acceptance. It is not
+a claim that every setup step is achievable through the current browser forms.
+The existing `test_onboarding_wizard.py` separately covers signup and invitation
+acceptance through the browser.
+
+`church.json` and `basketball.json` are the executable role/headcount fixtures.
+`tests/playbooks/` validates and discovers them for both test tiers. Each run creates new
+organizations and invitations with fictional `.example` addresses. Dates start
+on a Sunday at least two weeks ahead, avoiding expired-date tests.
+
+## Plug into pytest
+
+The plugin is registered in `tests/conftest.py`. Every test requesting the
+`playbook_spec` fixture runs once per discovered definition with a stable ID and
+the `playbook` marker. Existing API and browser CI lanes automatically run all
+bundled definitions; no workflow-file edits or separate CI job are needed.
+
+```bash
+# Select one domain; the browser tier still runs both viewport sizes.
+poetry run pytest tests/api/test_domain_playbooks.py --playbook church
+poetry run pytest tests/e2e/test_domain_playbooks.py --playbook basketball
+
+# Inspect the exact parameterized cases without creating any test data.
+poetry run pytest tests/api/test_domain_playbooks.py --collect-only -q
+
+# Load an external directory and run the example through each tier.
+poetry run pytest tests/api/test_domain_playbooks.py --playbook-dir tests/playbooks/examples --playbook food-bank
+poetry run pytest tests/e2e/test_domain_playbooks.py --playbook-dir tests/playbooks/examples --playbook food-bank
+
+# Filter to playbook tests within one tier; options are repeatable.
+poetry run pytest tests/api -m playbook --playbook church --playbook basketball
+```
+
+Run API and browser tiers in separate pytest processes, as CI does. Their event
+loop fixtures are different. `--playbook` filters playbook parameters only; use
+`-m playbook` or the explicit files to avoid running unrelated tests.
+
+To add a domain permanently, add one JSON file to `docs/playbooks/` using
+[the food-bank example](../../tests/playbooks/examples/food-bank.json) as a template.
+To load it temporarily, pass its directory with `--playbook-dir`. External
+directories augment the bundled definitions and cannot override duplicate IDs.
+Unknown selections, missing/empty directories, invalid JSON, unsupported versions,
+unsupported workflows, extra fields, and invalid role counts fail collection.
+
+Version 1 requires `id`, `version: 1`, `workflow: six_week_roster`, `name`,
+`event`, `secondary_event`, `roles`, and `critical_role`. IDs use lowercase letters,
+digits, underscores or hyphens; role codes use lowercase letters, digits or
+underscores. Both start with a letter. Role counts are positive integers, not
+booleans or numeric strings. The critical role must require exactly one person,
+matching the absence/shortage/replacement drill. Definitions contain no passwords,
+API keys, executable code or production endpoint settings.
+
+The runtime creates fresh organizations and a deep-copied definition per test.
+`tests/playbooks/workflows.py::run_six_week_roster` is reusable with the test
+client; `tests/playbooks/runtime.py::Playbook` exposes the lower-level actions and
+coverage oracle. A new pytest test can request `playbook_spec` to reuse discovery
+and selection without duplicating the list of domains.
+
+This is a domain-definition plugin for the six-week lifecycle, not an arbitrary
+workflow language. Adding a different lifecycle requires implementing and testing
+that workflow before accepting its identifier in `PlaybookSpec`. Do not accept
+unknown workflow IDs or silently skip unsupported scenarios.
+
+## Coverage map
+
+| Requirement | Automated evidence |
+| --- | --- |
+| Every required role filled by a distinct eligible person | API journey, every event in all six weeks; browser post-solve oracle |
+| Balanced load among interchangeable people | API baseline actual assignment counts, maximum difference one |
+| Planned absence uses a qualified reserve | API week 2 |
+| Simultaneous services/games use disjoint people | API week 3; overlap unit regression |
+| Missing role is reported instead of silently double-counted | API week 4; multi-skilled unit regression |
+| Qualified replacement repairs shortage | API week 5 |
+| Changed event time reaches regenerated roster | API week 6 |
+| Old published roster survives draft generation | API journey |
+| Repaired publication replaces old publication | API journey |
+| Volunteer, anonymous user, foreign admin cannot publish | API journey |
+| Draft invisible, published shift visible, member can accept | Browser journey, both domains |
+| Qualified reserve covers a swap without losing role coverage | Browser journey, both domains |
+| Draft/replaced assignments cannot be accepted, declined or swapped | API journey and web publication regression |
+| Multi-role form preserves exact names/counts | Browser journey, both domains |
+| Phone and desktop page width | Browser journey at 360 and 1440 pixels |
+| Adjacent events remain legal | Unit regression |
+
+Browser runs save onboarding and accepted-assignment screenshots in pytest's
+temporary test directory. Inspect them as well as assertion results. A horizontal
+overflow assertion alone is not a comprehensive visual/accessibility audit.
+
+## Known boundaries and release blockers
+
+- Only one solution per organization is published at a time. Regenerate the full
+  remaining horizon, not one isolated week, or future published shifts disappear.
+- Publication currently allows incomplete rosters. The playbooks require an admin
+  to resolve shortages first; the application does not enforce that policy yet.
+- Persisted custom constraints are not loaded by the API solver. Do not promise
+  maximum weekly load, rest/travel gaps, family grouping, or skill certification.
+- Team membership is not a proven eligibility boundary for role-based solving.
+  These fixtures use one scheduling organization and explicit role qualifications.
+- Scheduling role strings are not separate permission records. Use `admin` only
+  for administrators, `volunteer` plus scheduling roles for members. Browser
+  invitation controls do not expose the complete custom-role setup used here.
+- These tests prove publish authorization, not complete tenant security. Several
+  solution-read and availability routes still need authentication/isolation work.
+- Role-based solver assignments now retain their selected role. Old solutions
+  with null roles need regeneration; no existing data is silently rewritten.
+- The role-less team fallback, venue collision checks, DST/timezone transitions,
+  recurrence exception handling, real notification delivery, and PostgreSQL
+  concurrency require separate acceptance before production use.
+- Basketball playing minutes, substitutions during play, scores, standings and
+  league eligibility are outside this scheduling application.
+
+## Sign-off record
+
+For each release record: commit, command, date, pass/fail, screenshot location,
+scenario deviations, unresolved blockers, and the coordinator's approval.
+Do not mark manual scenarios passed merely because the automated suite is green.

+# Basketball scheduling playbook
+
+## Outcome
+
+Maintain a six-week basketball game and practice roster with five distinct player
+positions, coaching and scorekeeping coverage, available reserves and a reliable
+publish/respond workflow. This is roster scheduling, not live game management.
+
+Use Riverside Basketball as a fictional single-team sandbox. See
+[the acceptance guide](README.md) and executable [basketball.json](basketball.json).
+
+## People and responsibilities
+
+| Actor | Access | Responsibility |
+| --- | --- | --- |
+| Team manager | admin | Invite members, create sessions, review coverage, publish changes |
+| Coaches | volunteer + coach | Confirm availability and operational readiness |
+| Point guards | volunteer + point_guard | Cover one point-guard slot per event |
+| Shooting guards | volunteer + shooting_guard | Cover one shooting-guard slot |
+| Small forwards | volunteer + small_forward | Cover one small-forward slot |
+| Power forwards | volunteer + power_forward | Cover one power-forward slot |
+| Centers | volunteer + center | Cover one center slot |
+| Scorekeepers | volunteer + scorekeeper | Cover game table and practice/statistics duties |
+
+Prepare two people per role: ten players, two coaches and two scorekeepers.
+Use `volunteer` plus the listed scheduling role; coaching must not implicitly
+grant administrator access. Qualifications in this exercise describe the intended
+lineup, not league registration, age eligibility or medical clearance.
+
+## Initial setup
+
+1. Create the team organization and manager account. Invite fourteen people and
+   accept the invitations. Verify each scheduling qualification explicitly.
+2. Arrange venues and opponent/game details outside the solver. Use event titles
+   and organizational records consistently; the fixture has no opponent or league engine.
+3. Create six Sunday games, 10:00-12:00, with one of each player position, one
+   coach and one scorekeeper: seven distinct assignments per event.
+4. Create six Wednesday practices, 18:00-20:00, using the same role requirements
+   for this exercise. In a real team, adjust practice headcounts to the session plan.
+5. Ask members to record absences. Generate the full horizon and review the named
+   lineup rather than relying on the overall health score.
+6. Publish only after resolving gaps. Have members open their own schedules and
+   acknowledge the assignment. Keep reserves and communication arrangements explicit.
+
+## Weekly operating rhythm
+
+| When | Owner | Action and exit condition |
+| --- | --- | --- |
+| Monday | Manager | Review six-week game/practice calendar, venue changes and responses |
+| Tuesday | Players and staff | Record availability and known travel/injury absences |
+| Wednesday | Coach | Run practice; identify personnel changes for the upcoming game |
+| Thursday | Manager | Regenerate, check positions and staff, compare changes |
+| Friday | Coach + manager | Confirm lineup and reserves, publish and communicate |
+| Game day | Coach + scorekeeper | Verify actual attendance and handle in-game duties outside SignUpFlow |
+| After game | Manager | Review schedule workload and prepare the next rolling week |
+
+Equal assignment counts are not equal playing minutes. The application does not
+choose tactical substitutions or enforce league participation rules.
+
+## Six-week exercise
+
+| ID | Week / disruption | Actions | Acceptance |
+| --- | --- | --- | --- |
+| BB-01 | Baseline | Generate twelve events and publish | Five distinct positions plus coach and scorekeeper on every event; interchangeable baseline loads differ by at most one |
+| BB-02 | Player absent | Block one point guard for Sunday week 2 | That player is excluded that date; the other qualified point guard covers |
+| BB-03 | Overlapping game | Add week-3 game 11:00-13:00 | Disjoint players and staff cover both simultaneous games; no double-booking |
+| BB-04 | Position unavailable | Block both point guards for Sunday week 4 | That game has a reported point-guard shortage; failing draft is not published |
+| BB-05 | Replacement onboarded | Invite another qualified point guard | Regeneration repairs the gap without assigning a center or coach to that position |
+| BB-06 | Game postponed | Move week-6 game to Monday 10:00-12:00 | Regenerated schedule contains the new time with all roles covered; publication replaces the old version |
+| BB-07 | Player acknowledgement | View draft as player, publish, then accept | Draft is invisible to player; published assignment appears and can be accepted in browser |
+| BB-08 | Qualified swap | Request a swap and have a reserve for the same position cover | Original player loses the shift; reserve gains it; all position/staff slots remain covered |
+
+BB-01 through BB-06 run as an automated API lifecycle. BB-07/08 and multi-role form
+entry run in Chromium at phone and desktop sizes. The overlapping-game scenario
+is a staffing capacity drill, not a recommendation to split a competition team.
+
+## Additional operational drills
+
+Record these separately as manual/extended acceptance:
+
+1. A player requests a swap. Use a reserve qualified for the same position; verify
+   the roster has exactly one person in that slot and the original player loses it.
+2. A coach or scorekeeper withdraws on game day. Arrange qualified cover and verify
+   it is visible to both the replacement and manager before relying on it.
+3. A venue cancels a game. Coordinate the postponement, inspect calendar exports,
+   communicate the change and obtain responses. Automated court collision and
+   notification delivery are not established by this exercise.
+4. Two teams share players in one organization. Test team eligibility explicitly
+   before use; current role-based solving is not proven to restrict by team roster.
+5. A tournament needs travel/rest gaps. Validate manually; API solver integration
+   currently ignores saved custom constraints, so a configured gap is not proof.
+6. An injury affects several weeks. Record the correct date range, regenerate
+   the entire future horizon and follow the organization's separate return policy.
+7. A member needs calendar export or uses a different timezone. Check actual dates
+   and device rendering; these domain tests use UTC and do not certify DST behavior.
+
+## Release sign-off
+
+Require complete position/staff coverage, distinct people at overlapping times,
+absence compliance, visible published schedules and successful member acceptance.
+Keep game execution, playing time, league eligibility, delivery and security
+blockers separate from the scheduling acceptance result.

+| Children's ministry leaders | volunteer + children_leader | Confirm coverage and externally verified eligibility |
+| Ministry approver | Human organizational responsibility | Approve suitability, safeguarding and service changes outside the solver |
+
+Do not grant admin access merely because someone leads a ministry. The app has
+only admin/volunteer access levels, not department-scoped manager permissions.
+
+Prepare fourteen members: two worship leaders, four musicians, two sound
+operators, four ushers and two children's leaders. Assign one qualification per
+fixture person. A separate regression exercises a person qualified for two roles
+and proves that they cannot fill both slots in the same event.
+
+## Initial setup
+
+1. Create the organization and administrator account. Check the onboarding page
+   on a phone: the text and each action must remain readable and separate.
+2. Invite all fourteen members with `volunteer` plus their scheduling role.
+   Accept each invitation. Verify names and role strings before solving.
+3. Independently confirm each person's suitability for their ministry. A role
+   label is not evidence of training, background screening or safeguarding approval.
+4. Create six Sunday worship events, 10:00-12:00, one per week. Each needs one
+   worship leader, two musicians, one sound operator, two ushers and one children's
+   leader: seven distinct people, never six with one person counted twice.
+5. Create Wednesday 18:00-20:00 ministry preparation/rehearsal sessions for the same
+   six weeks and seven roles. Adapt actual ministry preparation duties to local practice.
+6. Ask members to enter time off. Review eligibility and absence before generating
+   the full six-week schedule in strict mode.
+
+## Weekly operating rhythm
+
+| When | Owner | Action and exit condition |
+| --- | --- | --- |
+| Monday | Administrator | Review upcoming six weeks, changes, staffing gaps and responses |
+| Tuesday | Members | Record new absences and request replacements early |
+| Wednesday | Ministry leads | Review preparation session attendance and next service needs |
+| Thursday | Administrator | Regenerate remaining horizon; compare old and new rosters |
+| Friday | Administrator + ministry approver | Resolve every gap, check each role, publish and communicate changes |
+| Before service | Ministry leads | Confirm actual attendance and arrange qualified last-minute cover |
+| After service | Administrator | Record follow-ups; review workload and prepare the next rolling week |
+
+SignUpFlow schedules people. Attendance, ministry suitability, actual communication
+and service execution remain human responsibilities, not inferred from a green solver score.
+
+## Six-week exercise
+
+| ID | Week / disruption | Actions | Acceptance |
+| --- | --- | --- | --- |
+| CH-01 | Baseline | Generate all twelve events and publish | Every event has seven qualified distinct assignees; interchangeable people's baseline loads differ by at most one |
+| CH-02 | Leader away | Block one worship leader for Sunday week 2; regenerate | The absent leader has no assignment that date; reserve fills the leader slot |
+| CH-03 | Extra service | Add week-3 service 11:00-13:00 | It overlaps 10:00-12:00; seven different people cover it; no person serves both |
+| CH-04 | No leader available | Block both worship leaders for Sunday week 4 | Exactly that service reports missing worship leadership; leave the failing draft unpublished |
+| CH-05 | New qualified cover | Invite and onboard a replacement worship leader | Regeneration fills week 4 and every other event; no other qualification is substituted |
+| CH-06 | Service moved | Move week-6 Sunday event to Monday 10:00-12:00 | New solution carries the changed time and full coverage; publishing replaces the previous solution |
+| CH-07 | Member acknowledgement | Open draft as assigned member, then publish and accept | Draft absent from member schedule; published assignment visible and acceptance confirmed in browser |
+| CH-08 | Qualified swap | Request a swap and have a reserve with the same qualification cover | Original member loses the shift; reserve gains it; every role remains filled |
+
+CH-01 through CH-06 are one automated API lifecycle with assertions after each
+state change. CH-07/08 and multi-role event entry run in Chromium at phone and desktop sizes.
+
+## Additional operational drills
+
+Record these separately as manual/extended acceptance, not as passed by CH-01-08:
+
+1. A sound operator requests a last-minute swap. Have a qualified, available reserve
+   cover it; verify the original person loses the shift and the sound role remains filled.
+2. A children's leader becomes ineligible. Remove that qualification, regenerate
+   every affected future event, and obtain ministry approval before republishing.
+3. A holiday changes service times or headcounts. Change only the intended events;
+   verify recurrence exceptions and avoid changing already completed services.
+4. A member never responds. Contact them through an approved channel and arrange
+   confirmed cover; do not treat an assignment's default status as delivery evidence.
+5. The venue is unavailable. Arrange a venue/time manually; the current playbook
+   does not establish automated room conflict prevention.
+6. Test a multi-skilled worship/sound member with another eligible specialist.
+   Review any greedy-solver shortage manually; a feasible schedule is not guaranteed
+   just because qualifications collectively appear sufficient.
+
+## Release sign-off
+
+Require exact role counts, no double-booking, no assignments during recorded
+absence, no unpublished drafts exposed in member schedules, and successful member
+acceptance. Recheck every future week after republishing. Keep human safeguarding,
+delivery, timezone and tenant-security blockers visible in the release record.

+# Acceptance evidence - 2026-09-12
+
+Run in the `SignUpFlow-production` worktree, starting from `9f94d56`, with
+Python 3.11, SQLite, real JWT/cookie sessions and Chromium. External email/SMS
+delivery was disabled. No customer organization was used.
+
+## Failures reproduced and repaired
+
+1. Both domain journeys initially failed because solution assignments omitted the
+   selected role. Preserve the solver's per-person role, save it in the existing
+   assignment column, and expose it as an optional response field.
+2. A multi-skilled person could conceal an unfilled role: coverage was counted
+   from qualifications rather than selected slots. Count actual selected roles.
+3. A person could be scheduled for overlapping events without explicit custom
+   constraints. Reject overlapping candidates; keep adjacent events legal.
+4. Browser members could see unpublished solver assignments. Apply the same
+   publication filter to member schedule lists, detail pages and self-service
+   API actions. Keep immediate manual assignments visible. Test that old
+   assignments become hidden/non-actionable after replacement publication.
+
+The existing SSE tests now explicitly publish their seeded solutions before
+testing member actions. An older recurring-event browser test exposed a click
+race; wait for HTMX settling before clicking its newly rendered Delete control.
+
+## Validation results
+
+| Check | Result |
+| --- | --- |
+| New church/basketball six-week API journeys | 2 passed inside the full API tier |
+| New domain browser journeys, 360px and 1440px | 4 passed, including qualified swaps |
+| Complete unit tier | 399 passed, 21 skipped |
+| Complete API tier | 444 passed |
+| Complete CLI tier | 16 passed |
+| Complete integration tier | 325 passed |
+| Complete web tier | 225 passed |
+| Complete browser tier | 33 passed on full rerun after timing repair |
+| OpenAPI snapshot contract | 1 passed after reviewed optional-field update |
+| Black / Ruff | Passed |
+| Strict mypy scope (`api/utils api/core api/schemas`) | Passed, 61 files |
+| Full API mypy | Existing debt: 835 errors in 40 files; not a pass |
+
+Total across the separate backend, web, browser and contract runs: 1,443 passed,
+21 skipped. `make test-all` completed successfully.
+
+The first full browser run had 32 passes and one recurring-delete timing failure.
+The targeted rerun and repaired full rerun passed; this initial failure is not
+omitted from the evidence. The first contract run failed on the intentional
+optional `role` addition, then passed with the reviewed snapshot.
+
+Inspected rendered phone onboarding and desktop basketball acceptance screenshots.
+The automated runs also save screenshots for both domains at both widths under
+pytest's temporary directories. Those images are disposable, not release archives.
+
+## Compatibility and limits
+
+The response adds an optional nullable `role`; existing required fields are unchanged.
+The current generated Dart deserializer ignores unknown fields (its `unhandled`
+collection is not rejected), so this does not require a mobile rollout. Exposing
+the new role in the mobile solution-review screen remains separate work.
+No database migration is needed: the assignment role column already exists.
+
+This is local acceptance evidence, not a production-readiness declaration or
+GitHub merge approval. See [remaining release blockers](README.md#known-boundaries-and-release-blockers).
+Do not count manual operational drills, external delivery, PostgreSQL, DST,
+venue scheduling or full tenant isolation as verified by these runs.
+
+## Pytest plugin integration
+
+Follow-up validation starting from `cccc6f7` uses the same local environment.
+The root pytest plugin discovers validated JSON definitions, provides isolated
+`playbook_spec` fixtures, marks generated cases, and supports repeatable
+`--playbook` and `--playbook-dir` options. Both existing acceptance runners now
+consume the fixture instead of maintaining a hard-coded domain list.
+
+- Plugin regression tests: 21 passed, including malformed definitions, duplicate
+  IDs, invalid selections, fixture isolation, and real pytest collection.
+- API acceptance with the external food-bank example: 3 passed.
+- Browser acceptance with that example: 6 passed across 360px and 1440px.
+- Complete browser suite: 33 passed.
+- Complete web and contract suites: 226 passed.
+- `make test-all`: 420 unit tests passed, 21 skipped; 444 API, 16 CLI, and
+  325 integration tests passed. Across backend, web, contract and browser suites:
+  1,464 passed, 21 skipped. The opt-in example runs above are additional evidence,
+  not included again in this total.
+- Black and Ruff: passed. Strict mypy scope: 61 files passed. Full API mypy
+  remains at the existing 835 errors in 40 files.
+
+The food-bank definition deliberately puts its critical role after another role
+to verify that the reusable workflow does not assume a church-specific role or
+dictionary order. It is opt-in example data, not an additional bundled domain.
+Existing CI API/browser lanes discover bundled definitions automatically.
+Version 1 supports `six_week_roster` only; this is not an arbitrary workflow engine.
+
+The first hosted run at `f9657df` exposed a test-tier dependency mistake: three
+plugin unit tests collected the browser module, but the backend CI environment
+does not install Playwright. Restrict unit-level collection probes to the API
+runner. Keep real browser execution in the existing Playwright lane and the
+separate external-definition browser run above; do not install browser packages
+into the backend lane or skip the plugin tests to hide the failure.
