Sprint Planner — Specification

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 SPEC 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 + JS-vendor copy + php:8.3-apache for runtime. The runtime stage installs pdo_sqlite, plus zip and gd (Phase 20 — required by PhpSpreadsheet); dom, xml, xmlreader, xmlwriter, simplexml, mbstring, fileinfo ship with the base image.
  • Language: PHP 8.3, strict types, PSR-12.
  • Database: SQLite via PDO, file at /var/www/data/app.sqlite (mounted volume).
  • Front end (Phase 19):
    • Templates: Twig 3 (*.twig under views/, {% extends %} inheritance, auto-escape ON, compiled cache in data/twig-cache/).
    • Styles: Tailwind CSS 3 compiled at image-build time (assets/css/input.css → public/assets/css/app.css). No CDN.
    • Behaviour: vanilla JS (delegated addEventListener, fetch) for the live grid pipelines (Arbeitstage cells, RTB, task days, task status, filters, sort) plus SortableJS for drag-reorder. Alpine.js (CSP build) drives small declarative components (hamburger menu, theme toggle). htmx wires the simple form-post pages (auth, settings, workers, users, sprint create, audit filter) for AJAX swaps without controller changes.
    • Strict CSP: script-src 'self' / style-src 'self' only — no unsafe-eval, no unsafe-inline, no third-party hosts. All JS deps vendored under public/assets/js/vendor/.
  • Auth: Microsoft Entra ID via OpenID Connect (Authorization Code + PKCE), plus an optional env-configured "local admin" fallback for dev / on-prem.
  • Composer deps: twig/twig, jumbojett/openid-connect-php, vlucas/phpdotenv, phpoffice/phpspreadsheet (Phase 20 — XLSX import wizard), phpunit/phpunit (dev).
  • npm deps (build-time only): tailwindcss, alpinejs, @alpinejs/csp, htmx.org, sortablejs.

4. Schema (migrations/001..004)

Tables (already applied): users, workers, sprints, sprint_weeks, sprint_workers, sprint_worker_days, tasks, task_assignments, audit_log, app_settings (Phase 18 — KV store for global flags), plus the schema_version tracking table.

Phase 22 (migration 004) adds three columns to tasks: description TEXT NOT NULL DEFAULT '', url TEXT NOT NULL DEFAULT '', and linked_task_id INTEGER REFERENCES tasks(id) ON DELETE SET NULL — set on a copy and pointed at the source. Plus index idx_tasks_linked.

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.
  • task_assignments.status ∈ {zugewiesen, gestartet, abgeschlossen, abgebrochen} (Phase 18). DB CHECK constraint enforces this.
  • 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/import | admin | | POST | /sprints/import | admin (multipart, _csrf) | | GET | /sprints/import/{token} | admin | | POST | /sprints/import/{token} | admin (form _csrf) | | GET | /sprints/{id} | signed-in | | GET | /sprints/{id}/present | signed-in | | GET | /sprints/{id}/settings | admin | | GET | /audit | admin | | GET | /settings | admin | | POST | /settings | admin (form CSRF via _csrf) |

JSON (admin-only, CSRF via X-CSRF-Token header; envelope per spec §7): | Method | Path | What | |--------|----------------------------------------------|---------------| | PATCH | /sprints/{id} | name/dates/reserve — when start_date or end_date changes, week rows are auto-resynced (count = ⌊(end−start)/7⌋+1, capped at 26; existing rows realign + audit) | | POST | /sprints/{id}/weeks | resize week set (legacy; UI no longer calls it — kept for back-compat) | | 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 (days only) | | PATCH | /tasks/{id}/assignments/status | batch cell status — any signed-in user; gated by app_settings.task_status_enabled (403 when off) | | POST | /tasks/{id}/move | move task to another sprint (drops assignments, audited) — Phase 22 | | POST | /tasks/{id}/copy | clone task into another sprint with linked_task_id = source.id — Phase 22 |

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.

  • [x] Phase 16 — Dark-mode toggle + light-mode contrast cleanup (94b2841). Two small palette issues addressed at once: (a) both body and table-header bands used bg-slate-50, so table headers blended into the page — body bumps one shade cooler to bg-slate-100 (the user's explicit ask), <thead> bands stay at bg-slate-50 and now read as a distinct lighter strip; (b) no dark palette existed at all, painful for the Phase 15 beamer view in dim conference rooms. Manual toggle only — no prefers-color-scheme auto-detect. tailwind.config.js gains darkMode: 'class'. New public/assets/js/theme-init.js (8 lines, synchronous <script src> in <head> before the stylesheet) reads localStorage['sp:theme'] inside a try/catch and sets <html class="dark"> if the value is 'dark' — no FOUC. views/layout.php and views/sprints/present.php both include the init script; the present route emits its own <!doctype html>, hence two tags. public/assets/js/app.js grows a third vanilla-JS IIFE (~17 lines) wiring [data-theme-toggle]: toggle the class on <html>, write sp:theme, stamp the [data-theme-label] text; writes wrapped in try/catch so private-window denials no-op. The toggle lives in the hamburger menu in views/layout.php as a new "Theme" row above the <hr> divider, visible to admins and non-admins alike (theme is a personal preference, not an admin action); the divider now always renders (previously only admins saw one) because the Theme row always renders. Every view file (views/layout, views/home, views/auth/local, views/workers/index, views/users/index, views/sprints/{new,settings,show, present}, views/audit/index) gets a systematic dark: sweep: body/card/header surfaces on the slate-900/800/700 ramp, borders on slate-700 (600 for inputs), primary text slate-100, secondary slate-400, inputs 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 / error / amber flash chips on *-900 backgrounds with *-200 text and *-800 borders, admin badge dark:bg-amber-900 dark:text-amber-200, Phase 12 weekday dots active dark:bg-green-400 / off dark:bg-slate-600, capacity "available" red dark:text-red-400, audit action chips similarly remapped. assets/css/input.css needed no edits — it carries no colour classes (only the .focus-auto-hidden utility and the .beamer-root typography block, both colour-free). Strict CSP stays intact (theme-init.js is a standard <script src> under script-src 'self'). Sign-out form block untouched — still a native POST with the _csrf hidden input. Zero PHPUnit — same pattern as Phases 10, 13, 14, 15; the change is CSS class additions plus ~25 lines of vanilla JS without a unit surface the existing harness can reach. Tests at 88 / 208. ACCEPTANCE.md gains a "Phase 16 — Dark mode + light contrast" section with the six scenarios from the plan (light-band separation, toggle flip, reload persistence under Network throttling + no FOUC, present view inherits dark, admin-pages contrast sweep, private-window localStorage denial fallback).

  • [x] Phase 17 — Hide native number spinners + custom slider popover for number inputs (b457896, UX tweak c07af1c, hotfix 832b256, rewrite 15b2d24, blur-fix f189ef7, close-fix 8d79f96, rebuild ff807c2, direct-listeners e93df6b). Three classes of number input — day cells, RTB cells, task assignment cells — deal in half-day increments (or 0.05 for RTB). Browsers rendered each as <input type="number"> with tiny native up/down spinner arrows: visually noisy in a dense table, inconsistent across Chrome / Firefox / Safari, useless on touch. Hidden app-wide via a two-rule @layer base block in assets/css/input.css (-webkit-*-spin-button { appearance: none; } + -moz-appearance: textfield). Week-count and reserve-percent inputs lose arrows too — fine, keyboard typing is their usual path. For the three opt-in cell types, a new public/assets/js/number-stepper.js (~180 lines, single IIFE, vanilla JS, no jQuery dep) delegates click + focusin on document to input[data-stepper]; on match, lazily builds a single .stepper-popover DOM node (role="dialog", − / <output> / + / hidden <input type="range">) and anchors it next to the bound input. Reads step / min / max off the input (default step=1); when both min and max parse as finite, un-hides the range slider and wires it; otherwise [data-assign] gets just the +/− buttons. clampToStep(current, delta, step, min, max) pure helper — adds delta, clamps to [min,max] when finite, quantises via Math.round(next/step) * step with a ~1e-9 epsilon tolerance so 0.6 + 0.05 = 0.65 lands cleanly. Every mutation mirrors into input.value and dispatches a bubbling synthetic input event, so sprint-planner.js's existing recomputeRow / row-total handlers fire live. On popover close (outside pointerdown, Escape, Tab-away, or clicking a different stepper input) the helper dispatches change — the existing debounced save pipeline (PATCH /sprints/{id}/week-cells, /workers/{sw_id}, or /tasks/{id}/assignments) fires once, same audit semantics as typed edits. ArrowUp / ArrowDown while focused on the input step by step (restores the shortcut the CSS reset just disabled). Position: below the input with a 4px gap unless the input sits in the lower 25% of the viewport, then above; horizontal clamp to viewport with 4px margins. Outside-click uses pointerdown (not click) so a Safari scroll gesture starting inside the popover doesn't dismiss it. data-stepper stamped on the admin-branch [data-day] / [data-rtb] / [data-assign] inputs in views/sprints/show.php, the [data-rtb] input in views/sprints/settings.php, the [data-assign] input in views/sprints/present.php, and the JS-built assignment cells in sprint-planner.js::buildTaskRow — non-admin <span> branches stay clean. Popover styled in assets/css/input.css under @layer components with Tailwind @apply on the Phase 16 palette (bg-white / dark:bg-slate-800 + slate-100/200/600/700 hover/border/text siblings + accent-slate-600/400 on the range). Both views/layout.php and views/sprints/present.php load the new module via <script src="/assets/js/number-stepper.js" defer> after sprint-planner.js — strict CSP stays intact, no inline handlers, no new external hosts. Zero PHPUnit — pure CSS + vanilla JS over existing markup, same pattern as Phases 10 / 13 / 14 / 15 / 16. Tests at 88 / 208. ACCEPTANCE.md gains a "Phase 17 — Number stepper popover" section with the five scenarios from the plan (no native arrows on any number input, day-cell stepper at 0.5 step, RTB stepper at 0.05 step, task-assignment stepper on both show and present views with no range slider because no max, Escape + outside-click + dark-mode polish). UX tweak c07af1c: the popover is now hover-to-open (pointerover / pointerout with a 200 ms grace timer so transit between input and popover is safe) instead of click-to-open, and the optional range slider renders vertically (writing-mode: vertical-lr + direction: rtl, with slider-vertical / orient="vertical" fallbacks). Focus and pointerdown triggers remain for keyboard and touch users respectively. Hotfix 832b256: readBounds() was using the IDL boundInput.max property which coerces a missing max attribute to the empty string and then to 0 via Number("") — the result was that task-assignment cells (which set min="0" but have no max) were clamped to [0, 0] and the +/− buttons appeared to do nothing on any table but the Arbeitstage grid. Switched to getAttribute()

    • explicit null/empty check so missing bounds report as NaN. Same commit centres the popover on the input's horizontal midpoint instead of aligning to its left edge — looks balanced over narrow table cells. Rewrite 15b2d24 lands the final interaction model: the popover is now slider only — no +/− buttons, no numeric output — opens on click (not hover) of any input[type="number"] app-wide (no data-stepper opt-in needed; the attribute stays harmless on the existing markup), anchors to the right of the input at its vertical midpoint, flips to the left when the right edge would clip the viewport, and closes as soon as the pointer leaves the popover after entering it at least once (a popoverEntered latch forgives click-to-open cursors that already sit inside the popover rectangle). Task-assignment inputs, which declare min="0" but no max, get an adaptive slider max of Math.max(current + 5, 10) so the slider is always useful. Dragging fires change on the bound input on every tick; sprint-planner.js's 400 ms debounce coalesces the flurry into one server write while its capacity recompute runs on every tick so Ressourcen / Available / ≤ reserves update smoothly during the drag. Escape, outside-pointerdown and Tab-out fallbacks remain for keyboard / touch paths. Blur-fix f189ef7 plugs a gap the rewrite left open: the popover now closes whenever focus leaves either the bound input or a focusable element inside the popover, unless focus is moving into another eligible number input (seamless rebind, no flicker). Catches the case where a click elsewhere blurred the input but never landed on a registered "outside" target. Replaces the Tab-specific keydown handler, which is now a subset of the generic focusout behaviour. Close-fix 8d79f96: the "mouse leaves" and outside-click paths were unreliable in real use — the dismissal required the cursor to physically enter the popover rectangle at least once (popoverEntered latch), so a user who clicked a cell and moved the cursor anywhere the popover wasn't would see the popup linger indefinitely. Replaced the latch with a document-level pointermove tracker: while the popover is open, if the cursor is over neither the bound input nor the popover for more than 150 ms, close. A 250 ms initial grace after open() covers the first few frames where the cursor may briefly be in the gap. Outside-click close is now registered in both bubble (pointerdown) and capture (click, {capture:true}) phases via a shared handler so a downstream stopPropagation can't strand the popup. The viewport-exit pointerleave on document is also a close trigger — the pointer heading for the browser chrome shouldn't leave the popup behind. Rebuild ff807c2: after seven iterations the file had accumulated contradictory event plumbing (hover-to-open co-existing with click-to-open, two close latches, two outside- click paths, stopPropagation on the popover's own pointerdown) and still failed in practice — the popup wouldn't close on drift or outside click, slider clicks sometimes stole focus without mutating the value, and the popup didn't follow the input on page scroll. Threw the file out and rebuilt it from scratch as a single ~250-line IIFE with exactly four concerns: open (click / focusin → configure slider + position), slider-to-input sync (one input listener mirrors elRange.value → boundInput.value and dispatches bubbling input+change events), close (pointer off both rects > 200 ms past a 300 ms open-grace window / viewport exit / capture-phase outside-pointerdown / Escape — all testing live getBoundingClientRect so repositioned popovers don't leave stale hit rects), and scroll anchoring (window.addEventListener('scroll', fn, {capture:true}) plus resize, rAF-throttled reposition; closes if the bound input collapses to 0×0). The CSS was untouched — the visual style is identical. Kept the ArrowUp/Down keyboard-nudge bonus that replaces the spinner-arrow shortcut. Direct-listeners e93df6b: even after the rebuild the close logic still didn't fire reliably — every close path was routed through document-level delegation (pointermove tracker, capture-phase pointerdown, pointerleave on document), and whatever was silently suppressing those events on the user's page suppressed all of them at once, leaving the popup stranded. Swapped the mouse-tracking close paths to element-local pointerenter / pointerleave listeners attached directly to the two elements that matter — the popover (once, in build()) and the bound input (per-open via bindInput(), detached via unbindInput() on close or rebind). pointerleave on either schedules close; pointerenter on either cancels it; the 300 ms open-grace keeps the timer rescheduling itself during the first 300 ms after click-to- open. Outside-click keeps the capture-phase document pointerdown, now with a 50 ms OPEN_IGNORE_MS guard so the opening click can't be misread as an outside click. Removed the document-level pointermove tracker, the document-level pointerleave viewport-exit handler, and the focusout handler entirely — superseded.

  • [x] Remove number-stepper slider popover (e551705): after seven iterations the click-to-open vertical-slider popover added in Phase 17 still didn't behave reliably, and the team prefers plain typed entry. Deleted public/assets/js/number-stepper.js, dropped the <script> tags from views/layout.php + views/sprints/present.php, removed the .stepper-popover CSS block from assets/css/input.css, and stripped data-stepper attributes from views/sprints/{show, settings,present}.php and the JS-built cell in sprint-planner.js::buildTaskRow. Kept the @layer base rule that hides native number-spinner arrows app-wide — typing is now the only edit path on every number input; ArrowUp/ArrowDown still steps via browser default. No schema / route / PHP changes; tests untouched at 88 / 208.

  • [x] Phase 18 — Per-cell task-status colours + filter + global toggle (9cb7669, hotfix 3e115f5). Each task- assignment cell on both /sprints/{id} and /sprints/{id}/present now carries a workflow status — zugewiesen (transparent, default), gestartet (yellow), abgeschlossen (green), abgebrochen (red) — picked from a chevron-only <select data-assign-status> next to the day input/span. The status colour class (assign-status-{state}) and data-assign-cell / data-status / data-sw-id attrs live directly on the <td> — the original commit's <span class="assign-cell"> wrapper turned out to be a layout trap inside table cells (display:inline-flex on a span around an input with a sibling select made the day inputs collapse on blur in production), so the hotfix flattened the structure: the day input is now a direct child of the <td>, the status select sits as a sibling, no wrapper. sprint-planner.js mirrors the chosen value into the wrapper class + data- status and queues a save through a new pendingStatus/flushStatus debounced pipeline that hits PATCH /tasks/{id}/assignments/status (400 ms, same semantics as the days pipeline). New "Status" multi-select filter sits between Owners and Focus in the toolbar; a row passes when at least one cell is in the picked set, with a special-case rule that the default zugewiesen only matches when days > 0 (so picking it doesn't include every task). State persists in localStorage (sp:{sprintId}:statusFilter, :beamer-namespaced for the present view) and is wiped by the existing Reset button. Schema: migrations/003_task_status_and_app_settings.sql adds task_assignments.status TEXT NOT NULL DEFAULT 'zugewiesen' with a CHECK constraint, and creates a new app_settings(key TEXT PK, value TEXT NOT NULL, updated_at TEXT NOT NULL) KV table seeded with ('task_status_enabled', '0') so the feature is opt-in. App\Repositories\AppSettingsRepository (get/getBool/set) reads it; SprintController::loadSprintPage() passes taskStatusEnabled + statusGrid into both views, which conditionally render the per-cell selectors and the toolbar Status filter. New admin-only /settings page (linked from the hamburger menu, App\Controllers\SettingsController) flips the toggle via a native form POST with _csrf; audit row entity_type='app_setting'. New PATCH /tasks/{id}/assignments/status is the first non- admin write surface in the app — gated by SessionGuard::requireAuthJson (auth + CSRF, no admin) plus app_settings.task_status_enabled (403 when off). Existing PATCH /tasks/{id}/assignments stays admin-only and days- only; TaskAssignmentRepository::upsert preserves status, ::upsertStatus preserves days and inserts a days=0 row when the cell didn't exist (so a state can be tracked before any work is assigned). Per-cell audit semantics unchanged — one row per changed cell. The four .assign-status-* class names are interpolated server-side, so tailwind.config.js gains a safelist keeping them in the build (Tailwind was silently dropping them otherwise — the :not() reference happened to keep zugewiesen in but the other three vanished). Strict CSP unchanged. Tests: 105 / 265 (was 88 / 208) — +TaskAssignmentTest (status enum + audit-snapshot shape), +AppSettingsRepositoryTest (seeded flag, get/set roundtrip, no-op equality, default fallback), +TaskAssignmentRepositoryTest (upsertStatus's four cases, days writes preserving status, InvalidArgumentException guard, statusGridForSprint).

  • [x] Cell popover replaces per-cell status select (10ea4b8): the Phase 18 chevron <select data-assign-status> next to each task-day input is gone. Clicking a day input (admin) or the new [data-assign-readonly] span (non-admin) now opens a single body-attached .cell-popover panel anchored 8 px right of the cell (flips left if it would overflow the viewport). Left column: a <input type="range" min="0" step="0.5"> whose max comes from a new admin-configurable setting assignment_slider_max (1..100, default 10); dragging mirrors into input.value and dispatches change, so the existing 400 ms debounced days-save pipeline + row total + capacity recompute fire unchanged. The slider is hidden on the non-admin path (no input to mirror). Right column: four status pills with coloured bullets (slate / yellow / green / red, matching the Status filter dropdown) — picking one is terminal: set data-status + .assign-status-* on the cell, queue the existing PATCH /tasks/{id}/assignments/status save, refresh filters, close. Other close triggers: outside pointerdown (capture phase, 50 ms grace after open so the opening click isn't misread), Escape, scroll / resize, and a 250 ms mouseleave grace. New AppSettingsRepository::getInt; SettingsController::KEYS shape changed from key=>label to key=>[type, label] so int + bool keys can coexist. Server clamps the int to [1, 100]; the per-cell day input itself stays unbounded (typing > max still works). The legacy .assign-status-select CSS block was deleted; the new .cell-popover* + .bullet-* block lives in the same @layer components section in assets/css/input.css. Strict CSP unchanged — no inline handlers, no new external hosts, the popover element is JS-built and appended once. Tests: 109 / ? (+1 for getInt round-trip + numeric-string guard); the prior 108 tests pass without modification. ACCEPTANCE.md gains a note pointing at the popover for the manual cell-edit flow.

  • [x] Filter dropdown close polish (9b72c41, 1864835): the Owners / Status / Columns dropdowns no longer get cropped when the task table holds a single row (overflow-hidden was on the section; replaced with rounded-t-lg on the toolbar div + rounded-b-lg on the table wrapper so the rounded corners survive). Each dropdown closes on mouseleave of its data-*-root element with a 250 ms grace timer that mouseenter cancels — the previous naive listener fired while the cursor was in transit across the mt-1 gap and shut the panel before the user could reach it. Owner / Status Clear now also closes the dropdown.

  • [x] Task table polish (f204611): three small UX bugs in the shared task list partial fixed in one commit. (a) Sortable headers (Task / Owner / Prio / Tot) gained whitespace-nowrap; previously the label and the ↕ sort indicator could wrap to two lines on narrow viewports. (b) Per-row assignment cells gained whitespace-nowrap so the day input and the Phase 18 status <select> always sit on the same line — no second-row flow when the cell shrinks. (c) .assign-status-select was effectively invisible — width: 1rem (16px), border: 0, font-size: 0, transparent background — bumped to 22×22 px with a real bordered button affordance, text-indent: -9999px to hide the selected text reliably (works where Safari's font-size: 0 cancels the chevron too), and a dark- mode variant. (d) .assign-status-* tint moved off the <td> onto the inner input[data-assign] / read-only span — cell padding no longer paints a stripe of status colour around the field; only the field itself reflects state. The class still lives on the <td> so the Status filter and JS reads off data-status are unchanged. buildTaskRow in sprint-planner.js mirrors the new whitespace-nowrap on JS-built assignment cells (admin "+ Add task" path). Pure CSS / Twig / vanilla JS — tests untouched at 108 / 281.

  • [x] Sprint view tabs + smart Close on present (2813019): /sprints/{id} is now split into two tabs — "Arbeitstage and capacity" (Arbeitstage matrix + capacity table + the snap/save help line) and "Capacity and tasks" (capacity table + task list

    • the 100 px popover-anchor spacer). The capacity table was extracted into a {% macro capacity_table(sprintWorkers, capacity) %} in views/sprints/show.twig and rendered twice via {{ _self.capacity_table(...) }}. sprint-planner.js's recomputeRow and applyServerCapacity switched from qs (first match) to qsa for the [data-cap-ressourcen|after- reserves|available] lookups so both copies update in lockstep on every edit, server response, and boot. A new initTabs IIFE in the boot section persists the active tab in localStorage under sp:{sprintId}:tab (:beamer-namespaced for parity with the other keys, even though the present view has no tab nav). Tab buttons use data-tab-btn/data-tab-panel plus Tailwind 3.4 data-[active=true]: variants for the underline + colour; no JS-driven class toggling needed beyond flipping data-active and the hidden class on the panels. Default tab is "arbeitstage" — survives until first selection, persists thereafter. The "Present" view's Close button is now smart: a new initSmartClose IIFE intercepts the click — if window.history.length > 1 (the user navigated to the present view within an existing tab), history.back(); otherwise window.close() with a 100 ms fallback to navigate to /sprints/{id} if the browser blocks close() (typed-URL or bookmark-opened pages can't always self-close). The link's href is preserved as the navigation fallback. Pure Twig + vanilla JS over existing endpoints — no schema, route, or audit changes; CSP unchanged. Tests at 108 / 281 (no PHP touched, no new test surface — same pattern as Phases 10, 13, 14, 15, 16). ACCEPTANCE.md not yet updated for the tab walkthrough.

  • [x] Phase 19 — Twig 3 + Tailwind 3 + Alpine CSP + htmx + SortableJS, jQuery removed (75e96e2). Stack-shift of the entire UI layer with zero changes to controllers, repositories, schema, capacity math, or audit semantics — every behaviour preserved end-to-end. All 11 views/*.php rewritten as views/*.twig using {% extends "layout.twig" %} inheritance; new layout-bare.twig backs /sprints/{id}/present's own <!doctype html>; new _task_list.twig partial is shared by show.twig and present.twig. src/Http/View.php now wraps Twig\Environment while keeping the historical render($name, $data, $layout) signature so controllers don't change; auto-escape ON; compiled cache written to data/twig-cache/ (gitignored, www-data-owned via the Dockerfile so first-render compilation succeeds). The legacy App\Http\e() helper stays defined for backwards compatibility but is unused by Twig templates. ~1500 lines of jQuery / jQuery UI deleted from app.js, sprint-planner.js, sprint-settings.js; each rewritten as a pure-vanilla IIFE using fetch + delegated addEventListener against the existing JSON-envelope endpoints. SortableJS replaces jQuery UI sortable on the three drag-reorder lists. Alpine (CSP build, @alpinejs/csp — no unsafe-eval) drives the hamburger menu (appMenu factory) and theme toggle (themeToggle factory); everything else is vanilla JS. htmx loaded site-wide; CSRF token attached via htmx:configRequest; hx-boost="true" sprinkled on the simple form-post pages (/auth/local, /workers create+edit, /users/{id}, /settings, /sprints/new, /audit filter) so submissions AJAX-swap the body without a full reload. Sprint show/settings/present pages stay native — their page-specific IIFEs would not re-init after a body swap. CSP tightened: script-src 'self' and style-src 'self' only — https://code.jquery.com dropped from every directive. Dockerfile css-builder stage now also vendors node_modules/{@alpinejs/csp,htmx.org,sortablejs}/dist/*.min.js into /build/vendor/, which the runtime stage COPYs into public/assets/js/vendor/ (gitignored). New runtime dep twig/twig ^3.10; new dev deps alpinejs, @alpinejs/csp, htmx.org, sortablejs. Tests: 108 / 281 (was 105 / 265) — new tests/Http/TwigViewTest.php adds three smoke renders (home as signed-in admin, audit/index empty, sprints/show with task grid + status filter); the prior 105 tests pass without modification. tailwind.config.js content glob switched from views/**/*.php to views/**/*.twig. The number-spinner reset (@layer base block in assets/css/input.css) and Phase 18 .assign-status-* safelist + status-select styling all carry over unchanged.

  • [x] Phase 20 — XLSX import wizard (8876239). Two-step admin-only wizard at /sprints/import that ingests the team's historical Tool_Sprint Planning.xlsx workbook into the database one tab per sprint. Step 1 is a multipart upload form with strict validation (≤ 5 MB, .xlsx extension, PK\x03\x04/PK\x05\x06 ZIP magic-byte check). Step 2 (/sprints/import/{token} where token is a 32-char hex random session key, TTL 30 min) shows one preview panel per parsed sheet: sprint-name input pre-filled from the tab name, inferred start/end dates pre-filled from KW-row + closest-year heuristic (using setISODate() over ±1 year and picking the nearest match to today), reserve fraction read-only from the workbook, target picker (Create new sprint / Merge into empty existing sprint — non-empty sprints are filtered out of the dropdown server-side), diff summary listing workers-to-create + assignment-cell totals + per-status colour counts, and a per-sheet "skip" toggle. New service trio: App\Services\Import\XlsxColorClassifier (pure ARGB → status, hue/saturation thresholds with no PhpSpreadsheet dep — bins green H 80..170/S>0.15, yellow+orange H 20..80, red H 340..20/S>0.20, everything else → zugewiesen; near-white L>0.96 and S<0.10 banding both fall through to default), App\Services\Import\ XlsxSprintImporter (parses with the fixed coordinate map locked down from the sample file: C6 = "Arbeitstage" / E.. = max working days, C7 = "Datum", C8 = "KW", C9.. worker name + E.. per-week days + J RTB + K Σ-formula, J{r} = "Reserven" ends the worker block; M4 = "Tasks", Q4.. worker-name formulas (=C9, =C10, …) for the authoritative task-column → Arbeitstage worker mapping which skips Arbeitstage gaps, M9..P9 = To Do/Owner/Prio/Tot header, M10.. task title with N owner, O prio, Q.. per-worker assignments; the parser tolerates up to 2 consecutive empty rows in both blocks so the sample workbook's row-13 visual gap doesn't truncate Sprint 2), and App\Services\Import\SprintImporter (transactional commit that creates or merges-into-empty sprints, materialises sprint_weeks with active_days_mask = (1 << maxDays) − 1 and max_working_days = popcount(mask), auto-creates missing workers by case-folded exact name with audit each, drops task-owner names that don't resolve into the global Workers table into a missingOwners warning list and creates the task with owner_worker_id = NULL, writes per-week days through the existing SprintWorkerDayRepository::upsert and per-cell days

    • status through TaskAssignmentRepository::{upsert,upsertStatus} so the same audit semantics already in production carry over; one IMPORTED_FROM_XLSX audit row per sprint anchors the run). Composer dep: phpoffice/phpspreadsheet ^3.4. Dockerfile runtime stage adds zip + gd (PhpSpreadsheet require) on top of the existing pdo_sqlite. New App\Domain\Import\ value objects (ParsedSheet/Week/Worker/Task/Assignment + ImportResult) round-trip through toArray()/fromArray() so the parsed result can be JSON-stashed in $_SESSION['sp_imports'][$token] between steps without persisting the uploaded file to disk. Hamburger menu gains an "Import" link next to "New sprint" for admins. Strict CSP unchanged — no JS in the wizard, native form posts throughout. Tests: 143/392 (was 108/281) — pure-table-driven XlsxColorClassifierTest (20 cases incl. all six fills observed in the sample workbook + edges like fully-transparent, pure white, pure red, lavender), XlsxSprintImporterTest (5 smoke tests against doc/Tool_Sprint Planning.xlsx: 3 sheets parsed, Sprint 1 shape 5w/15w/>20t/0.2 reserve, Sprint 2 colour-count matches openpyxl audit (27 yellow/orange → gestartet, 5 green → abgeschlossen, 0 red), Sprint 2 16-worker count tolerating the row-13 gap, toArray/fromArray round-trip — auto-skipped when host PHP lacks dom/zip/xmlreader/simplexml/gd so the suite stays portable to thin developer environments), SprintImporterCommitTest (5 cases on the in-memory SQLite harness: full new-sprint commit shape + audit row count, refuse to merge into a non-empty existing sprint, case-folded worker reuse with leading/trailing whitespace, maxDaysToMask table, fold normalisation), ImportControllerTest (3 cases on the static helpers via reflection: ZIP magic-byte detection, wrong extension rejection, UPLOAD_ERR_* mapping). The classifier test was originally written with the legacy @dataProvider doc-block annotation; PHPUnit 11 deprecated metadata in doc-comments so we use the #[DataProvider] attribute.

  • [x] Phase 21 — Auto-derived week count in sprint settings: the "Set to N / Apply" form is gone; PATCH /sprints/{id} now resyncs sprint_weeks whenever start_date or end_date changes. Target count = floor((end − start)/7) + 1, capped at 26 (422 above). Existing rows are realigned (SprintWeekRepository::realignDates rewrites start_date/iso_week per sort_order offset, preserving active_days_mask); appended rows default to MASK_ALL; trailing rows shrink with the same audit-cascaded-days flow as the legacy replaceWeeks. The response gains a weeks_synced flag so sprint-settings.js can reload the page after a date edit. The per-week weekday checkboxes (Mo Di Mi Do Fr) and POST /sprints/{id}/weeks are unchanged — the JSON endpoint is kept for back-compat but the UI no longer calls it. +5 tests, 148 total.

  • [x] Phase 22 — Per-task hamburger menu: move / copy / edit / reorder (c2dad80). Replaces the SortableJS drag handle on the task table with a per-row hamburger button (admin only) that gathers every task-level action: Edit details… (modal with a description textarea, ≤8000 chars plain text, plus a url input — empty or http(s)://, ≤2048 chars), Move to sprint… (submenu of every other sprint), Copy to sprint… (same submenu), Move (pick up) (click-to-pickup → row follows cursor Y with an amber drop indicator → click-anywhere-to-drop, Escape cancels), Delete (the standalone × column was folded in). Worker-row SortableJS stays put — only the task-table draggable was removed. Title cell gains: a small external-link anchor when url is set (target="_blank" rel="noopener", visible to all), a description marker that opens a read-only popover (so non-admins can read descriptions without the edit modal), and bidirectional linked- task chips ("← Sprint X" for the source row, "→ Sprint Y" for every row that copies back). Two new admin-only JSON endpoints: POST /tasks/{id}/move (audits each task_assignment DELETE before the cascade, then UPDATE on tasks.sprint_id — task lands at MAX+1 in the destination's sort_order) and POST /tasks/{id}/copy (creates a fresh task with title / owner / priority / description / url cloned and linked_task_id = source.id; assignments are dropped per the design call). PATCH /tasks/{id} accepts description and url alongside the prior whitelist; URL is validated server-side (^https?:// or empty). Schema: migrations/004_task_metadata_ and_links.sql adds tasks.description TEXT NOT NULL DEFAULT '', tasks.url TEXT NOT NULL DEFAULT '', tasks.linked_task_id INTEGER REFERENCES tasks(id) ON DELETE SET NULL, and idx_tasks_linked — existing rows stay valid without backfill. TaskRepository::linkedSummariesForTasks() resolves both directions in two queries off the per-sprint task list; SprintController::loadSprintPage passes sprintChoices (every sprint except this one) + linkedMap into the show + present views, and the JS reads sprintChoices from a JSON-encoded data-sprint-choices attribute on data-task-section. The details modal, hamburger menu, description popover, and pickup indicator are all single body-attached nodes built lazily by sprint-planner.js — no Alpine, no htmx swap, strict CSP stays intact (no inline handlers, no new external hosts). New @layer components block in assets/css/input.css defines .task-menu + .task-menu-{item,sub-item,...}, .task-modal- {overlay,panel,header,body,footer}, .task-pickup-{active, indicator}, and .task-desc-popover; the Phase 15 beamer rule grows a [data-task-menu-trigger] hide so the present view stays read-only. Tests: 148 / 406 — unchanged. The new fields default empty/NULL so existing TaskRepository / cascade / status tests keep passing without modification; the migrator picks up 004 on next request.

Upcoming

Nothing scheduled.

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.

Run the test suite:

vendor/bin/phpunit
# → OK (143 tests, 392 assertions)

The Phase 20 parser tests need ext-dom, ext-zip, ext-xmlreader, ext-simplexml, and ext-gd (PhpSpreadsheet's hard requires); on hosts that don't have all of them the parser tests auto-skip via extension_loaded() in setUp(). Run inside the Docker image when the host PHP is thin:

docker compose build
docker run --rm -v "$(pwd):/app" -w /app sprint_planer_web-app:latest \
    sh -c "git config --global --add safe.directory /app \
        && composer install --no-interaction --no-progress \
        && vendor/bin/phpunit --colors=never"

12. How to resume in a fresh Claude session

Tell Claude:

Working on /Users/achiappa/Development/claude_code_private/sprint_planer_web. Read SPEC.md, the git log, and ACCEPTANCE.md. Phases 1–22 are shipped (see §9; Phase 17's slider popover was removed — typed entry is now the only edit path on number inputs; Phase 18 added per-cell task-status colours + filter + a new /settings page gated by a global flag that's off by default; Phase 19 swapped the stack to Twig 3 + Tailwind 3 + Alpine CSP + htmx + SortableJS and removed jQuery + jQuery UI completely; Phase 20 added a two-step XLSX import wizard at /sprints/import powered by PhpSpreadsheet, with a colour-coded cell → status mapping; Phase 21 derives the sprint week count from start/end dates; Phase 22 replaced the task drag handle with a per-row hamburger menu — Edit details / Move across sprints / Copy across sprints (with bidirectional linked- task chips) / click-pickup reorder / Delete; tasks gained description / url / linked_task_id columns). Nothing is currently scheduled. Outstanding items are in §10 (mostly a human-run acceptance walkthrough in the running container). If I ask you to plan or work a new phase, follow the maintenance rule in §14 — commit code, then commit a SPEC.md update separately that marks the new work 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:

  1. Commit the code first. A commit message that captures what changed, why, and how it was verified is the canonical record.
  2. 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.
  3. Update §13. Append the new SHA to the git history block.
  4. If new files / directories were added or moved, refresh §3.
  5. If the test count changed, update §11's expected count.
  6. Commit the SPEC.md update as its own commit. Keeping it separate means a git revert of the code revert leaves the doc honest by reverting alongside.
  7. 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.
