docs: refresh CLAUDE.md + parked-work for 15 May session wins

CLAUDE.md changes:
- 'What's mid-flight' breadcrumb updated: SiteReport/Absences
  migrations are LIVE on prod; only the 4 latest UX commits await
  a pull-and-restart (no migration / collectstatic needed).
- URL Routes table entries for /workers/ and /history/ now document
  the new ?team= filter (and team=none for unassigned / no-team cases).
- Worker Management UI inline description mentions the team filter
  + Absences tab on the worker detail page.
- Two new Coding Style gotchas captured: (1) Bootstrap dropdowns
  inside .card elements get clipped by sibling cards — fix is to
  lift the wrapping card with position:relative + z-index;
  (2) JS reading from data-worker-id was unreliable on production —
  read input[name="workers"][value] directly (the attendance-form
  pattern that's been working for years).

parked-work.md changes:
- Pending-deploy section rewritten: the BIG deploy (migrations +
  collectstatic) is DONE; only 4 small commits await a pull +
  service restart.
- 'Recently shipped' grew two new entries: the team filters on
  /workers/ + /history/, and the two absences UX polish fixes.
- Updated timestamp to 15 May 2026.

+`0014_add_absence`, `0015_absence_project` are deployed; `/history/`
+is no longer crashing on the production VM. The Worker Absences
+feature shipped on 14 May 2026 (commits `bf6f0a5` → `27fe05e` on
+`ai-dev`). Subsequent UX polish (multi-checkbox-dropdown stacking
+fix, absence-form team-filter bug fix, team filter added to
+`/workers/` and `/history/`) is on `ai-dev` HEAD but not yet on
+production — needs a `git pull` + `sudo systemctl restart

 - When creating or editing code, maintain the existing comment structure
 - **Django template comments `{# ... #}` are SINGLE-LINE only.** Multi-line blocks need `{% comment %}...{% endcomment %}`. A `{#` on line N with no closing `#}` on the same line renders the whole block as literal text onto the page (and silently — no error). This bit us 4× during the Adjustments feature. Also: the literal tokens `{#` and `#}` cannot appear inside a `{% comment %}` block — they'll be parsed as a nested comment marker. Rephrase meta-notes about comment syntax OUTSIDE the block.
 - **Duplicate `id=""` attributes cause silent bugs.** `document.getElementById()` returns only the FIRST match in DOM order, so adding a second element with an existing id silently steals the handler from the original. Grep the template before assigning any new id (caught `adjSelectAll` collision in Task 6 — header checkbox stole the Add-Adjustment modal's Select-All handler).
+- **Bootstrap dropdowns inside `.card` elements get clipped by sibling cards.** A `.dropdown-menu` with `z-index: 1050` rendered inside a filter `.card` will STILL appear behind a sibling table `.card` that follows in document order. Bootstrap's `transform: translate(...)` Popper positioning creates a new stacking context — the z-index is measured INSIDE the parent card, not globally. The fix: lift the wrapping element (e.g. the filter `<form class="card">`) with `style="position: relative; z-index: 10;"` so the entire card sits above its siblings. The dropdown's local z-index then resolves correctly. Bit us on the Absences filter dropdown (May 2026).
+- **JS reading from `data-worker-id` was unreliable; read from `<input name="workers">[value]` directly.** Round A's first absence-form team filter rendered `data-worker-id="{{ worker.choice_value }}"` on the row `<div>` and read it via `row.dataset.workerId`. On production this hid ALL workers when a team was selected — likely a stale-template / template-render mismatch. The proven pattern (used by `attendance_log.html` for years) is to read `row.querySelector('input[name="workers"]').value`. The form widget's `<input value="<pk>">` is the source of truth; data attributes are an unnecessary indirection.

 - Quick Adjust Button: Each pending payments row has an "Adjust" button (slider icon) that opens the Add Adjustment modal with that worker pre-checked and their most recent project pre-selected. The header "Add Adjustment" button resets the modal to a clean state. Uses `_quickAdjustOpen` flag to distinguish between the two open paths.
 - Worker Lookup Modal: Clicking any worker name on the payroll dashboard (or using the "Worker Lookup" button) opens a modal with a comprehensive report card — amount payable, outstanding loans, paid this month/year, loans this year, recent activity (last payslip, loan, repayment, advance), active loans table, current project + days on project, PPE sizing, drivers license, and notes. Uses `worker_lookup_ajax` AJAX endpoint. Worker dropdown in modal allows switching workers without closing.
 - Team & Project Management UIs: Friendlier alternatives to `/admin/core/team/` and `/admin/core/project/`. Reachable via the "Resources" dropdown in the topbar (admin only). **Team pages**: `/teams/` (list + search/filter), `/teams/<id>/` (detail with Profile/Pay Schedule/Workers/History tabs — Pay Schedule tab uses the existing `get_pay_period()` helper to show current + next 2 periods), `/teams/<id>/edit/` (single-page form for name, supervisor, pay schedule, and workers M2M). **Project pages**: `/projects/`, `/projects/<id>/` (tabs: Profile/Supervisors/Teams/Workers/History), `/projects/<id>/edit/` (form for name, description, dates, supervisors M2M). Uses `TeamForm` and `ProjectForm` from `core/forms.py` (both simple ModelForms, no inline formsets). Batch reports at `/teams/report/` and `/projects/report/` with CSV exports; PDF exports deferred as a follow-up. Dashboard "Manage Resources" card now has "Manage All Workers/Projects/Teams" footer links on each tab. Django admin remains fully functional as a fallback.

Uses `WorkerForm`, `WorkerCertificateFormSet`, `WorkerWarningFormSet` from `core/forms.py`. The "+ Add Certification" / "+ Add Warning" buttons clone a `<template>` element via `content.cloneNode()` (DOM-safe, no innerHTML) and rewrite `__PREFIX__` in input names to the next formset index.

 - Worker Batch Report: `/workers/report/` shows every worker with aggregated lifetime history — days worked, projects worked on, teams, first/last payslip dates, total paid, cert status (active/total + expired/expiring counts), warning count. Filter by status, project, team. CSV export via `/workers/report/csv/`, PDF via `/workers/report/pdf/` (landscape A4, same amber-accent typography as the payroll report). Built on the reusable `_build_worker_report_context()` helper which uses `annotate(Min/Max/Count/Sum)` + prefetch for efficient aggregation.
 - Dashboard cert-expiry card: The admin dashboard shows a "Certifications Need Attention" stat card with count of expired + expiring-within-30-days certs (active workers only). Card is CONDITIONAL — renders only when count > 0, so it disappears when everything is in good standing. Clicking it goes to the worker batch report. Counts come from `index()` view adding `certs_expired_count`, `certs_expiring_count`, `certs_alert_total` to context.
 - **Inline Filters on the Report page**: `/report/` has three pill-buttons (Date / Projects / Teams) in a sticky strip. Clicking a pill opens an inline popover with the editor for that filter. Popover's OK rebuilds the URL and navigates — no "dirty state", no global Apply. Date popover has a Single/Range/Custom mode toggle; Projects + Teams use Choices.js multi-select. Bidirectional project↔team cross-filter disables workers/projects that never paired in the selected date range. Context key `project_team_pairs_json` is consumed via `|json_script` (raw Python list — NEVER `json.dumps` it first; the filter does the serialisation and double-encoding silently breaks `.forEach(...)`). Deleted the old `_report_config_modal.html`; Dashboard "Generate Report" button is now a plain link with the current month pre-filled.

-## ⚠ Needs operator action (production)
+## ⚠ Pending pull-and-restart on production
 
-### Production deploy of SiteReport + Absences (pending Konrad)
+**Status:** The big absences/SiteReport deploy (migrations
+`0013`/`0014`/`0015` + collectstatic + service restart) was
+completed on 14 May 2026 — `/history/` no longer crashes,
+`/absences/*` is reachable, badge CSS is collected. ✓
 
-**Status:** All code committed and pushed to `origin/ai-dev` (HEAD
-`27fe05e` as of 14 May 2026 late evening). Production at
-`https://foxlog.flatlogic.app/` has pulled the new code but is
-crashing on `/history/` with:
+Since that deploy, four small commits have shipped to `origin/ai-dev`
+that are NOT yet on production:
 
-```
-ProgrammingError: (1146, "Table 'app_38686.core_sitereport' doesn't exist")
-```
+| Commit | What it does |
+|---|---|
+| `4368e53` | Fixes the absence-form team filter (workers were all disappearing when a team was selected — read input.value instead of data-attr) |
+| `02c6d4d` | Fixes the Reasons multi-checkbox dropdown stacking-context bug on `/absences/` (lifted the filter card above the table card) |
+| `4b57cff` | Adds a Team filter to `/workers/` |
+| `398a5b2` | Adds a Team filter to `/history/` (and CSV export) |
 
-**Why:** Flatlogic auto-pulled the new code but didn't run migrations.
-The new template logic references `log.site_report`, which queries a
-table that doesn't exist yet on the production MySQL.
+**To deploy these:**
+- No migrations needed (pure template + view changes; no schema changes).
+- No `collectstatic` needed (no new CSS or JS files).
+- Just: ask Gemini in Flatlogic to `git pull origin ai-dev` and then `sudo systemctl restart django-dev.service`.
 
-**The fix (~2 minutes total):**
-
-1. **Backup first** (safety net) — visit
-   `https://foxlog.flatlogic.app/backup-data/` while logged in as
-   admin. Download the `.json` file to a safe location.
-2. **Run pending migrations** — visit
-   `https://foxlog.flatlogic.app/run-migrate/`. Applies three
-   migrations:
-   - `0013_add_site_report` — creates `core_sitereport` table (fixes
-     the immediate /history/ error)
-   - `0014_add_absence` — creates `core_absence` table
-   - `0015_absence_project` — adds `project` FK to absence
-3. **Refresh static files + restart service** — ask Gemini in
-   Flatlogic to run:
-   ```
-   python3 manage.py collectstatic --noinput
-   sudo systemctl restart django-dev.service
-   ```
-   Needed because `static/css/custom.css` has new
-   `.badge-absence-*` rules — without `collectstatic`, the reason
-   badges on the new pages will render with no color.
-4. **Smoke test (incognito)** — visit `foxlog.flatlogic.app/history/`
-   (should load), `/absences/` (should load), `Resources →
-   Absences` (admin dropdown should now have it). Log one test
-   absence end-to-end.
-
-**Rollback if anything breaks:** visit
-`https://foxlog.flatlogic.app/restore-data/`, upload the backup
-from step 1, ask Gemini to restart the service.
-
-**Why this is parked, not urgent:** The /history/ error only fires
-when someone actively uses the History page. The dashboard,
-attendance log, and payroll pages all work fine. Konrad chose to
-defer the deploy step — that's the right call when you don't have
-time to babysit a deploy properly.
-
-**Reference:** the deployment hazard is documented in CLAUDE.md
-under "Migrations" in the Flatlogic/AppWizzy Deployment section.
+That's the whole sequence. Production should pick up all four
+improvements instantly. Rollback is `git reset --hard <previous SHA>`
+on the VM if anything looks wrong (no data migrations were involved,
+so rollback is safe).
