Sprint Planner — Handoff

Single source of truth to resume work in a fresh session. Keep this file in sync with the code; if something here disagrees with the repo, trust the repo.

Maintenance rule (read first, then keep doing it). After every commit that completes a phase or substantive change, update §9 (move the entry from Upcoming → Shipped with the SHA) and §13 (git history). If new files were added, refresh §3. Commit the HANDOFF update separately. See §14.

1. What this is

A web replacement for an Excel sprint-planning workbook used by a ~15-person ops/dev team. One sheet per sprint in the original; per sheet:

Arbeitstage matrix (top): max working days per week + per-worker availability per week.
Task list (bottom): one row per task with priority, owner, total days, and a per-worker days-allocated cell for each sprint worker.

The web app reproduces that workflow with proper auth, database, and per-cell audit trail.

2. Tech stack (non-negotiable)

Runtime: Docker, two-stage build, node:20-alpine for CSS + php:8.3-apache for runtime.
Language: PHP 8.3, strict types, PSR-12.
Database: SQLite via PDO, file at /var/www/data/app.sqlite (mounted volume).
Front end: server-rendered PHP templates + Tailwind CSS (vendored, compiled by the Node stage) + jQuery 3.x + jQuery UI 1.13 (from code.jquery.com CDN).
Auth: Microsoft Entra ID via OpenID Connect (Authorization Code + PKCE), plus an optional env-configured "local admin" fallback for dev / on-prem.
Composer deps: jumbojett/openid-connect-php, vlucas/phpdotenv, phpunit/phpunit (dev).
npm deps: tailwindcss (build-time only).

4. Schema (migrations/001_init.sql + 002_sprint_week_active_days.sql)

Tables (already applied): users, workers, sprints, sprint_weeks, sprint_workers, sprint_worker_days, tasks, task_assignments, audit_log, plus the schema_version tracking table.

sprint_weeks.active_days_mask INTEGER NOT NULL DEFAULT 31 (Phase 12) is a 5-bit mask — bit0=Mo, bit1=Di, bit2=Mi, bit3=Do, bit4=Fr — and is the source of truth for "is this a workday this week." max_working_days lives on as a cached popcount(mask) projection, so the two columns are always in sync.

Indexes: idx_audit_occurred_at, idx_audit_entity, idx_tasks_sprint, idx_sw_sprint.

Value constraints enforced in PHP (not SQL):

All days fields: non-negative multiple of 0.5.
sprint_weeks.max_working_days ∈ {0, 1, 2, 3, 4, 5} — derived from the weekday mask, so half-days are gone at the week level (Phase 12).
sprint_weeks.active_days_mask ∈ 0..31 (bits Mo..Fr).
sprint_worker_days.days ∈ {0, 0.5, …, 5}.
task_assignments.days ≥ 0, no hard upper bound.
reserve_fraction, rtb ∈ [0, 1].

FK cascades (every cascade path now snapshot-audits before the parent delete runs — Phase 8):

sprint_weeks.sprint_id → sprints(id) ON DELETE CASCADE
sprint_workers.sprint_id → sprints(id) ON DELETE CASCADE
sprint_workers.worker_id → workers(id) ON DELETE RESTRICT
sprint_worker_days.sprint_worker_id → sprint_workers(id) ON DELETE CASCADE
sprint_worker_days.sprint_week_id → sprint_weeks(id) ON DELETE CASCADE
tasks.sprint_id → sprints(id) ON DELETE CASCADE
tasks.owner_worker_id → workers(id) ON DELETE SET NULL
task_assignments.task_id → tasks(id) ON DELETE CASCADE
task_assignments.sprint_worker_id → sprint_workers(id) ON DELETE CASCADE

5. Capacity math (spec §6.5)

Runs identically in App\Services\CapacityCalculator (PHP) and in sprint-planner.js (JS). Any edit must touch both.

round_half(x)  = round(x * 2) / 2
ressourcen     = Σ sprint_worker_days.days per sprint worker
after_reserves = round_half(ressourcen * (1 − sprint.reserve_fraction))
committed_p1   = Σ task_assignments.days where task.priority = 1
available      = after_reserves − committed_p1

Priority-2 assignments do NOT consume capacity (they're "nice to have"). A negative available turns the cell red but is not blocked.

6. Routes

Pages (HTML): | Method | Path | Auth | |--------|-----------------------------|----------------| | GET | / | any (anon → sign-in CTA) | | GET | /healthz | — | | GET | /auth/login | — | | GET | /auth/callback | — | | GET | /auth/local | — (404 if disabled) | | POST | /auth/local | — (404 if disabled) | | POST | /auth/logout | signed-in | | GET | /workers | admin | | POST | /workers | admin | | POST | /workers/{id} | admin | | GET | /users | admin | | POST | /users/{id} | admin | | GET | /sprints/new | admin | | POST | /sprints | admin | | GET | /sprints/{id} | signed-in | | GET | /sprints/{id}/present | signed-in | | GET | /sprints/{id}/settings | admin | | GET | /audit | admin |

JSON (admin-only, CSRF via X-CSRF-Token header; envelope per spec §7): | Method | Path | What | |--------|----------------------------------------------|---------------| | PATCH | /sprints/{id} | name/dates/reserve | | POST | /sprints/{id}/weeks | resize week set | | POST | /sprints/{id}/workers | add sprint worker | | DELETE | /sprints/{id}/workers/{sw_id} | remove sprint worker (audits cascaded children) | | POST | /sprints/{id}/workers/reorder | reorder sprint workers | | PATCH | /sprints/{id}/workers/{sw_id} | set rtb | | PATCH | /sprints/{id}/week-cells | batch day cells | | PATCH | /sprints/{id}/week/{week_id} | set active_days_mask or active_days (derives max_working_days) | | POST | /sprints/{id}/tasks | create task | | POST | /sprints/{id}/tasks/reorder | reorder tasks | | PATCH | /tasks/{id} | title/owner/priority | | DELETE | /tasks/{id} | delete task (audits cascaded assignments) | | PATCH | /tasks/{id}/assignments | batch assignment cells |

Response envelope:

Success: {"ok": true, "data": …}
Failure: {"ok": false, "error": {"code", "message", "details?"}}
Validation errors: HTTP 422.

7. Audit logging rules (cross-cutting)

App\Services\AuditLogger::record(action, entityType, entityId, before, after, userId, userEmail, ip, ua) is called inside the same transaction as the DB change. Controllers prefer recordForRequest(..., Request, ?User) to drop the repeated plumbing.

Every CREATE / UPDATE / DELETE on a domain table → exactly one row.
Bulk operations (batch cell save) → one row per changed cell.
A no-op UPDATE (canonical-JSON-equal before/after) → no row.
FK-cascading deletes must be audited by the controller BEFORE calling the cascading delete. References:
- TaskController::delete() — task → task_assignments
- SprintController::removeWorker() — sprint_worker → sprint_worker_days + task_assignments
- SprintController::replaceWeeks() — sprint_week → sprint_worker_days (on shrink)
Non-mutation events (LOGIN, LOGOUT, LOGIN_FAILED, BOOTSTRAP_ADMIN) → always one row.

8. Env (.env.example)

ENTRA_TENANT_ID=
ENTRA_CLIENT_ID=
ENTRA_CLIENT_SECRET=
APP_BASE_URL=http://localhost:8080
SESSION_SECRET=
DB_PATH=/var/www/data/app.sqlite
SESSION_PATH=/var/www/data/sessions
APP_ENV=production

# Optional local admin fallback (disables when blank).
# Password is compared verbatim (not hashed) — .env must be file-permissions
# protected. The resulting user is entra_oid="local:<email>", is_admin=1.
LOCAL_ADMIN_EMAIL=
LOCAL_ADMIN_PASSWORD=
LOCAL_ADMIN_NAME=Local Admin

First-login bootstrap: when the users table is empty at the moment of successful login (either OIDC or local), that user is promoted to is_admin=1 with a BOOTSTRAP_ADMIN audit row.

9. Build phases — status

Shipped

Phase 1 — Skeleton (58a6b30)
Phase 2 — Auth (be193d2, hotfix 83493d0): Entra OIDC with PKCE, session + CSRF, first-user-is-admin bootstrap, local-admin fallback.
Apache routing fix (82ddc98): FallbackResource /index.php.
Phase 3 — Workers + sprints + audit (f189e7d).
Phase 4 — Sprint settings (38ba151): meta edit, weeks resize, worker membership add/remove/reorder, per-row RTB.
Phase 5 — Arbeitstage grid (515d7d0): editable matrix, capacity calc, per-cell persistence with audit.
Phase 6 — Task list (ad78283): CRUD, assignments grid, sort/filter/search, drag-reorder.
SRI hotfix (927b708): guarded sortable() calls.
Phase 7 — Audit viewer + polish (21d0c4a): /audit admin page with filters + pagination + collapsible diffs, security headers + strict-ish CSP, CSRF audit (18/18 mutations), PHPUnit harness with 59 tests. ACCEPTANCE.md captures the spec §10 manual walkthrough.
Phase 8 — Cascade audit integrity (dd158f3): three FK cascade paths (sprint_worker → sprint_worker_days, sprint_worker → task_assignments, sprint_week → sprint_worker_days on shrink) now snapshot-audit before the parent delete fires. +4 tests, +2 repo lookup methods.
Phase 9 — Users management (f7f5db5): GET /users + POST /users/{id} with self-demote and last-admin guardrails. Pure static UserController::demoteGuardrail is testable with no PDO/session setup. +6 tests.
Phase 10 — Task list polish (c35a934, hotfix 7c298d3): multi-select owner filter (checkbox dropdown) and column-visibility toggle, both pure client-side with localStorage persistence per sprint. Hotfix 7c298d3 repairs a regression c35a934 left in sprint-planner.js: ownerChoices() still scraped the pre-Phase-10 [data-owner-filter] option selector (replaced by [data-owner-filter-opt] checkboxes in this phase), so every client-built task row (admin clicks "+ Add task") had an empty owner dropdown until a page reload re-rendered it server-side. Also affects the Phase 15 /sprints/{id}/present view since it reuses the same toolbar markup + JS.
Phase 11 — CSP hardening (ab9430b): vendored Tailwind via a Node css-builder Docker stage; inline onclick replaced by data-href + app.js; CSP dropped 'unsafe-inline' and the Tailwind CDN host. Strict CSP now in effect.
Phase 12 — Per-week weekday selection (Mo–Fr) drives Arbeitstage (a634582, follow-up UI 1aca417): sprint_weeks.active_days_mask is the new source of truth; max_working_days is a cached popcount(mask) projection. Sprint Settings exposes five checkboxes (Mo Di Mi Do Fr) per week. The sprint view's Arbeitstage row shows a row of five dots per week (green = active, gray = off) — no labels, tooltip carries the day names. PATCH /sprints/{id}/week/{week_id} now accepts active_days_mask or active_days; max_working_days in the body is rejected. Migration 002 backfills legacy rows (half-days round up, clamped to 0..5). +14 tests, 88 total (was 74).
[x] Phase 13 — Focus filter + Reset in the task list (b027c5d, hotfix 23ab365): new [data-focus-select] in the task-list toolbar picks one sprint worker; applyFilters() grows a fourth AND predicate hiding rows whose [data-assign][data-sw-id="{focus}"] is not > 0, and a new applyFocusColumnVisibility() tags every sw column that is all-zero across the remaining visible rows with .focus-auto-hidden (a one-line utility added to assets/css/input.css — does NOT touch hiddenCols, so clearing focus restores the user's manual Columns picks). [data-reset-filters] wipes search, prio, ownerFilterSet, focusWorker, and hiddenCols in one click and re-hides itself. All state lives in localStorage (sp:{sprintId}:focusWorker joins the existing namespace). Pure client-side; no schema, route, or audit changes. Tests unchanged at 88 (the phase is 100% JS over existing HTML, same pattern as Phase 10). Hotfix 23ab365 stamps data-col on JS-built task cells in buildTaskRow, which was a pre-existing gap exposed by both the Columns dropdown (Phase 10) and this phase's focus auto-hide — new-task cells are now recognised by both systems.
[x] Phase 14 — Hamburger menu groups admin utilities + Sign out (101cc57): views/layout.php moves Workers / Users / Audit log / Sign out into a dropdown behind a <button data-menu-trigger> with an inline-SVG hamburger (three <line>s, stroke-current, no external asset). The <div id="app-menu" data-menu role="menu" hidden> panel is absolutely positioned with min-w-[12rem], rounded border, bg-white shadow-lg, items px-3 py-2 text-sm hover:bg-slate-50 plus a focus ring. Admins see Workers / Users / Audit log / <hr> / Sign out; non-admins see just Sign out (no divider). Sprints, New sprint (admin only), and the user badge stay inline. Sign out remains a native <form method="post" action="/auth/logout"> with the _csrf hidden input — no JS-driven POST. public/assets/js/ app.js gains a ~30-line vanilla-JS IIFE (document. querySelector + addEventListener, no jQuery) that toggles hidden + aria-expanded on click, closes on outside-click / Escape (returning focus to the trigger) / any role= "menuitem" click. CSP stays strict. Zero PHPUnit changes — 88 / 208 holds. ACCEPTANCE.md gains a "Phase 14 — Hamburger menu" section with the four manual scenarios from the plan.
[x] Phase 15 — Big-screen (beamer) task viewer at /sprints/{id}/present (d1dda4f). New signed-in route renders a stripped-down view: no shared layout chrome, no Arbeitstage matrix, no capacity summary — just a thin top bar (sprint name + dates + Close) and the task-list toolbar
- table. SprintController::show() keeps its behaviour; the shared data fan-out is extracted into a private loadSprintPage(int $id): ?array helper that both show() and the new present() method call, returning null for a missing sprint so each caller renders its own 404. views/sprints/present.php emits its own <!doctype html> (rendered with layout=null) reusing /assets/css/app.css
- the jQuery / jQuery UI CDN tags from layout.php + /assets/js/sprint-planner.js defer. The root <main> carries beamer-root + data-sprint-root + data-sprint- id + data-csrf + data-reserve-fraction + data- beamer="1". sprint-planner.js detects the beamer flag, namespaces its three localStorage keys with a :beamer suffix (so presentation filters don't clobber the user's /sprints/{id} workflow), seeds ["owner","prio","tot"] into hiddenCols:beamer on first load (before the first applyColumnVisibility() so nothing flashes), and after the boot applyFilters() measures table.scrollWidth > container.clientWidth; if it overflows, adds .beamer-vertical-headers (rotates sw column headers 90°); if it still overflows, console.warns and falls through to horizontal scroll — never a hang. Strict CSP unchanged. CSS scoping block lives under @layer components in assets/css/input.css (.beamer-root table typography + padding, .handle + [data-delete-task] hidden, vertical- header rule). Entry point is a new "Present" anchor next to Settings in views/sprints/show.php, target="_blank" for all signed-in users. Tests unchanged at 88 / 208 — refactor is a pure extraction and the sanity test the plan allowed was skipped because the existing tests/ Controllers/ harness only runs pure statics; a full controller integration test would need PDO + session wiring out of scope for this phase. ACCEPTANCE.md gains a "Phase 15 — Big-screen viewer" section with the six manual scenarios from the plan.

Upcoming

[ ] Phase 16 — Dark-mode toggle + light-mode contrast cleanup

Problem. Two things are slightly off in the current theme:
```
1. Every page uses `bg-slate-50` on `<body>` and the table
   `<thead>` bands *also* use `bg-slate-50` — so the headers
   blend into the page. Cards (white) pop, but table
   headers vanish.
2. Users working in low-light rooms or on projectors/beamers
   (Phase 15!) want a dark palette. Today there's no switch,
   no CSS scoping for it, and Tailwind's dark variants are
   disabled — adding `dark:` classes right now would be
   dead weight.
```
Goal. One toggle, global per-browser, that flips the whole app between a light and dark palette. In light mode, push the page background one shade cooler so the table header bands visibly separate from the page; in dark mode, pick a neutral-slate ramp that's legible at a distance on a beamer without being pure black. No system-preference auto-detect — the user asked for manual control.

Scope (plan).
1. Tailwind config (tailwind.config.js).
  - Add darkMode: 'class' so dark: variants activate only when <html class="dark"> is set. No change to the content globs — the JIT already scans views/**/*.php and public/assets/js/**/*.js, so every new dark:bg-… class we type ends up in the compiled CSS.
2. Theme init — new public/assets/js/theme-init.js.
  - Tiny synchronous script (≤ 6 lines, no deps). Reads localStorage.getItem('sp:theme') and, if it is 'dark', calls document.documentElement.classList.add('dark'). Empty / missing / any other value means light.
  - Loaded from <head> synchronously (no defer, no async) right before the stylesheet, so there's no FOUC flash between bright and dark on page load.
  - Same file is injected by both views/layout.php and views/sprints/present.php (Phase 15 emits its own <!doctype html>). Since the CSP already allows script-src 'self', the new file just needs a standard <script src> tag — no inline, still CSP-clean.
3. Light-mode rebalance (the user's explicit ask).
  - Body: bg-slate-50 → bg-slate-100. Slightly cooler page gray.
  - Table headers stay at bg-slate-50, so against the new page background they now read as a distinct lighter band. No structural change — just the body tint shifts.
  - Card sections (bg-white) already pop above slate-100 — unchanged.
  - Hamburger-menu dropdown and sprint toolbar bg stay white — the existing shadow + border already separate them.
4. Dark-mode palette.
  - Ramp (all Tailwind defaults so they work with the vendored build):
    - body: dark:bg-slate-900
    - cards / panels: dark:bg-slate-800
    - table header bands: dark:bg-slate-700
    - borders: dark:border-slate-700
    - primary text: dark:text-slate-100
    - secondary text: dark:text-slate-400
    - inputs / selects / textareas: dark:bg-slate-800 dark:border-slate-600 dark:text-slate-100 dark:focus:ring-slate-500
    - links: dark:text-blue-400 dark:hover:text-blue-300
    - success flash: dark:bg-green-900 dark:text-green-200 dark:border-green-800
    - error flash: dark:bg-red-900 dark:text-red-200 dark:border-red-800
    - admin badge: dark:bg-amber-900 dark:text-amber-200
    - Phase 12 weekday dots: active dark:bg-green-400, off dark:bg-slate-600 (brighter on-state so they still read from the back of a room)
    - capacity "available" red: dark:text-red-400
  - Apply these in one sweep across every view plus public/assets/css/app.css's input classes (input.css is the source; it's the only hand-edited CSS).
5. Toggle UI — hamburger menu (Phase 14).
  - Above the <hr> that separates admin items from Sign out in views/layout.php, insert a Theme row:
```
<button type="button" role="menuitem" data-theme-toggle
       class="w-full text-left px-3 py-2 text-sm
              text-slate-700 hover:bg-slate-50 flex
              items-center justify-between
              dark:text-slate-200 dark:hover:bg-slate-700">
 <span>Theme</span>
 <span data-theme-label class="text-slate-500
                               dark:text-slate-400">
   Light
 </span>
</button>
```
  - Non-admin users also get this row (not gated on $currentUser->isAdmin) — theme is a personal preference, not an admin action.
  - The Phase 14 menu-controller in app.js already closes the dropdown on any role="menuitem" click; we piggyback on that and add a separate handler that flips the class.
6. JS — extend public/assets/js/app.js.
  - ~10 new lines. On click of [data-theme-toggle]: toggle dark on <html>, persist localStorage['sp:theme'] ('dark' or 'light'), update the [data-theme-label] text. On boot (after theme-init.js already decided the initial state), read the class state and stamp the label so the hamburger opens with the correct word showing.
7. Sweep — views to touch.
  - views/layout.php — body bg, header border/bg, hamburger button colours, menu panel, badge, status chip, main container.
  - views/home.php — sprint-row hover states, empty banner.
  - views/auth/local.php — login card + inputs.
  - views/workers/index.php, views/users/index.php — list tables + buttons.
  - views/sprints/new.php, settings.php — form cards, inputs, "Apply" button, weekday checkboxes.
  - views/sprints/show.php — Arbeitstage table, capacity card, task toolbar, dropdowns, task table, weekday dots, focus/reset buttons.
  - views/sprints/present.php — same task-list markup as show; reuses input.css. Also needs to include theme-init.js in its own <head>.
  - views/audit/index.php — filter pills, audit rows, collapsible diffs (if present).
  - assets/css/input.css — base form-control layer: add dark: siblings for every class used by form inputs.
8. Edge cases.
  - FOUC on a slow connection. theme-init.js is synchronous + before the stylesheet, so the class is set before any style resolves. Should look seamless. Test with devtools throttling on the acceptance walkthrough.
  - Private-mode / localStorage denied. try/catch around the read and write; default to light.
  - Dark-mode beamer view. People projecting in a dim conference room will appreciate this most. Make sure the Phase 15 present route picks up the class. Verified by adding theme-init.js to present.php's own <head>.
  - Existing inline styles that use Tailwind colours (e.g. bg-green-500 on the weekday dots) stay — we add dark:bg-green-400 next to them. Tailwind handles both states from the same class list.
  - Third-party CSS — jQuery UI base theme. The code.jquery.com base CSS still loads from CDN and is not dark-aware. jQuery UI only shows up during drag operations (worker reorder, task reorder); its ghost element looks slightly out of place in dark mode. Accept and note in §10 deferred items.
9. Tests. Zero PHPUnit. The phase is CSS class additions plus ~10 lines of vanilla JS — pattern-matches Phases 10, 13, 14, 15 which all skipped automated coverage. Manual acceptance in ACCEPTANCE.md under a new "Phase 16 — Dark mode + light contrast" section: (a) fresh page load in light mode: body is cooler than
```
   the table headers (visible band separation);
```
  (b) click Theme in the hamburger menu → whole app flips
```
   to dark; label reads "Dark";
```
  (c) reload the page → dark persists, no flash of light
```
   before styles apply;
```
  (d) open /sprints/{id}/present in a new tab → picks up
```
   dark too (theme-init.js included in its head);
```
  (e) back to light mode, open Workers / Users / Audit /
```
   Settings pages: no stray white-on-white or
   unreadable text anywhere;
```
  (f) private-window (localStorage denied) → defaults to
```
   light, toggle no-ops without throwing.
```
Out of scope.
- prefers-color-scheme auto-detection. User explicitly asked for manual control only.
- Per-user server-side theme preference (storing in the users table). Browser-local is enough for now.
- High-contrast accessibility mode (WCAG AAA). Separate concern; revisit if someone needs it.
- Re-theming jQuery UI. See edge cases; deferred to §10.
- A third "sepia" / "paper" mode. Two modes only.
Spec alignment.
- §3 layout: add public/assets/js/theme-init.js to the public/assets/js/ block.
- §4 / §5 / §7: no changes — no new schema, math, or audit surface.
- §6 Routes: unchanged — CSS + JS only.
- §11 phpunit count stays at 88.
- Strict CSP (§ Phase 11) stays intact — theme-init.js is a standard <script src> under script-src 'self'.

10. Residual known gaps / deferred items

Worker reorder on /sprints/{id} reloads the page after drag so the task list's worker columns stay in sync. Acceptable, but noisy if the user has a lot of edits in flight (they're all saved by then). Not scheduled; the reload is fast and the alternative (live-reordering columns in JS) is complex for little win.
OIDC library raises PHP 8.4 deprecations. jumbojett/openid-connect-php 1.0.2 uses implicitly-nullable params. The container runs 8.3 where these are E_DEPRECATED but still emit — harmless, and silenced by ini_set('display_errors','0') in production. Upstream library needs a release.
Manual acceptance walkthrough (ACCEPTANCE.md) hasn't been executed end-to-end by a human yet — it's a documentary follow-up that should happen in the running container.

11. Running locally

cp .env.example .env
# Fill Entra vars, OR set LOCAL_ADMIN_EMAIL + LOCAL_ADMIN_PASSWORD
docker compose up --build
# open http://localhost:8080

Rebuild when the Dockerfile / composer manifest / Tailwind sources change:

docker compose build --no-cache && docker compose up

For local CSS dev without Docker:

npm install
npm run watch:css   # rebuilds public/assets/css/app.css on change

The SQLite file lives at ./data/app.sqlite on the host; nuking it resets the app to a blank slate (migrations run on the next request).

Syntax-check PHP without Docker:

for f in $(git ls-files '*.php'); do php -l "$f" | tail -1 | sed "s|^|$f: |"; done

Run the test suite:

vendor/bin/phpunit
# → OK (88 tests, 208 assertions)

12. How to resume in a fresh Claude session

Tell Claude:

Working on /Users/achiappa/Development/claude_code_private/sprint_planer_web. Read HANDOFF.md, the git log, and ACCEPTANCE.md. Phases 1–15 are shipped (see §9); Phase 16 (manual dark-mode toggle + light- mode contrast cleanup) is planned but not implemented — the scope is in §9 under Upcoming. Other outstanding items are in §10 (mostly a human-run acceptance walkthrough in the running container). If I ask you to work Phase 16, follow the maintenance rule in §14 — commit code, then commit a HANDOFF.md update separately that moves the entry from Upcoming → Shipped with its SHA.

Claude should verify what's described here against actual repo state before acting — nothing here is load-bearing once it grows stale.

Each commit message captures the deliverables, rationale, and the smoke tests that were run to validate it. Read those in preference to any summary here.

14. Maintenance contract

The previous §14 was the plan for Phases 8–11. All four shipped, so the plan moved into §9. This section now codifies the rule that produced this file in the first place — don't lose it on a context reset.

After every commit that completes a phase or substantive change:

Commit the code first. A commit message that captures what changed, why, and how it was verified is the canonical record.
Update §9. If the work matched a planned phase, move it from Upcoming → Shipped with the SHA. If it didn't match a planned phase (hotfix, infra fix, etc.), insert it inline with the SHA.
Update §13. Append the new SHA to the git history block.
If new files / directories were added or moved, refresh §3.
If the test count changed, update §11's expected count.
Commit the HANDOFF.md update as its own commit. Keeping it separate means a git revert of the code revert leaves the doc honest by reverting alongside.
If the change affects the resume prompt in §12 (e.g. a new "next phase" or a deferred-work item gets resolved), update that too.

Why: a fresh Claude session starts by reading this file. Stale status here is the single biggest source of duplicated or wrong work. Keeping the file truthful costs ~2 minutes per phase; recovering from a stale file costs more.

If you skip these steps, the next session will eventually notice and have to rebuild the picture from git log and the codebase. That's recoverable, but a regression from why this file exists.
