# Inline Filters (Pill-as-Dropdown) Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Replace the modal-based filter form on `/report/` with interactive pill-dropdowns (Apply button appears only when pending changes exist, bidirectional project↔team cross-filter auto-removes invalid selections), and retire `_report_config_modal.html` entirely.

**Architecture:** Template-only change except for one backend tweak. The existing filter-pill strip (shipped with Executive Report v2) becomes clickable — each pill opens a Bootstrap-like popover containing the relevant editable widget (date picker or Choices.js multi-select). A scoped IIFE JS module inside `report.html` manages popover state, tracks dirty filters, and rebuilds the submit URL on Apply. Cross-filter data comes from a single JSON `<script type="application/json">` embed serialised by the view. The modal + Generate/New Report buttons are deleted since pills ARE the new-report interface.

**Tech Stack:** Django 5.2.7 · Python 3.13 · SQLite (local) / MySQL (prod) · Bootstrap 5.3 · Font Awesome 6 · Choices.js 10.2.0 (CDN, already loaded from the just-shipped executive report) · WeasyPrint (PDF unchanged). Existing patterns: `# === SECTION ===` comments, plain-English docstrings, `json_script` template filter, `createElement` + `textContent` (XSS-safe JS).

**Design source:** `docs/plans/2026-04-23-inline-filters-design.md` (local commit `30d0991`, not yet pushed).

**Commit convention:** One commit per task. Co-Authored-By trailer. Never amend. All local-only until the feature is complete and Konrad approves the push.

**Reference schema gotchas** (from CLAUDE.md):
- `PayrollAdjustment.description` (not `reason`)
- `log.adjustments_by_work_log` (not `payrolladjustment_set`)
- `log.overtime_amount` (not `log.overtime`)
- For M2M filters in `.values().annotate(Sum())`: use `id__in=Model.objects.filter(...).values('id')` (avoid chained `.filter(m2m__x=a).distinct()` — N² inflation)

**Key existing line references** (HEAD `12edafa`):

- `core/templates/core/report.html`: 401 lines total
  - Lines 20-23: header "New Report" button (opens modal — to delete in Task 5)
  - Lines 34-49: filter-pill strip from recent work (editable in Tasks 2-4)
  - Lines 387-389: bottom "New Report" button (to delete)
  - Line 400: `{% include 'core/_report_config_modal.html' %}` (to delete)
- `core/templates/core/index.html`: 607 lines total
  - Lines 187-190: "Generate Report" Quick Actions card (anchor + modal trigger — become plain link in Task 5)
  - Line 605: `{% include 'core/_report_config_modal.html' %}` (to delete)
- `core/templates/core/_report_config_modal.html`: 160 lines — **delete entire file in Task 5**
- `core/views.py`:
  - Lines 434-435: `selected_project_ids` / `selected_team_ids` in `index()` context (remove in Task 5)
  - Lines 2395-2404: same context keys in `generate_report` view + block comments explaining the stringformat pattern (remove in Task 5)
- `static/css/custom.css`: 1735 lines total
  - Lines 1496-1524: existing `.filter-pill` + `.filter-pill__x` rules (extend in Task 3)

---

## Review checkpoints

**One checkpoint** after Task 4 — all pill interactions demonstrable in the browser; modal still on the page as a fallback. After Konrad confirms the interactive behaviour is right, Tasks 5-6 retire the modal and ship.

---

## Task 1: Backend — `project_team_pairs_json` context key + 1 test

**Why first:** tiny, low-risk, non-breaking. The template doesn't consume the new key yet (that's Task 2), so this commit alone changes nothing visible. Prepares the data source for the JS cross-filter in Task 4.

**Files:**
- Modify: `core/views.py` (one line inside `generate_report` view around line 2395, plus an import)
- Modify: `core/tests.py` (append new test class)

**Step 1.1: Check `json` import**

Grep to confirm `import json` is already at the top of `core/views.py`:

```bash
grep -n "^import json\|^from json" core/views.py
```

Expected: present (used elsewhere). If missing, add `import json` near the other stdlib imports.

**Step 1.2: Write the failing test**

Append to `core/tests.py`:

```python
# =============================================================================
# === TESTS FOR INLINE FILTERS (Report Page) ===
# Pill-as-dropdown + cross-filter feature. Most behaviour is template/JS;
# the only backend surface is the project_team_pairs_json context key that
# powers the client-side Team↔Project cross-filter.
# =============================================================================


class InlineFiltersPairsContextTests(TestCase):
    """Report view must serialise distinct (project_id, team_id) pairs for
    the pill-popover cross-filter JS."""

    def setUp(self):
        self.admin = User.objects.create_user(
            username='admin-if', password='pass', is_staff=True
        )
        self.p1 = Project.objects.create(name='P1')
        self.p2 = Project.objects.create(name='P2')
        self.t1 = Team.objects.create(name='T1', supervisor=self.admin)
        self.t2 = Team.objects.create(name='T2', supervisor=self.admin)

            log = WorkLog.objects.create(
                date=datetime.date(2026, 3, 1),
                project=proj, team=team, supervisor=self.admin,

        import json as _json
        self.client.login(username='admin-if', password='pass')
        url = reverse('generate_report')

        # No pair should have team_id=None
        self.assertTrue(all(p['team_id'] is not None for p in pairs))
```

**Step 1.3: Run the test — expect failure**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py test core.tests.InlineFiltersPairsContextTests -v 2
```

Expected: `KeyError: 'project_team_pairs_json'` or similar "context key not found" failure.

**Step 1.4: Implement in `generate_report`**

Find `generate_report` view in `core/views.py` (around line 2380). Locate the section where `context['query_string'] = request.GET.urlencode()` is set (around line 2385). Just after that, add:

```python
    # === Cross-filter source: serialised (project_id, team_id) pairs ===
    # The pill-popover JS on the report page uses this to hide teams that
    # haven't worked on a selected project, and vice versa. Scope = entire
    # history (not this report's date range) — cross-filter is about data
    # possibility, not data in this period.
    pairs = list(
        WorkLog.objects
        .filter(project__isnull=False, team__isnull=False)
        .values('project_id', 'team_id')
        .distinct()
    )
    context['project_team_pairs_json'] = json.dumps(pairs)
```

(Verify `json` is imported at the top of the file; if not, add `import json` near the other stdlib imports.)

**Step 1.5: Run the test — expect pass**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py test core.tests.InlineFiltersPairsContextTests -v 2
```

Expected: `Ran 2 tests ... OK`. Full suite:

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py test core.tests -v 0 2>&1 | tail -5
```

Expected: `Ran 44 tests ... OK` (42 existing + 2 new).

**Step 1.6: Commit**

```bash
git add core/views.py core/tests.py
git commit -m "$(cat <<'EOF'
Backend: add project_team_pairs_json context for inline-filter cross-filter

Serialises distinct (project_id, team_id) pairs from WorkLog as JSON on
the generate_report context. The upcoming pill-popover JS (Task 4 of the
inline-filters plan) uses this to hide teams that haven't worked on a
selected project (and vice versa) without any extra HTTP round-trips.

Scope: entire history (not the report date range) — cross-filter is about
data possibility, not data shown in this period. Filters out NULL
project or team (can't cross-filter on NULL).

2 tests cover: key is populated with correct pairs; NULL-team logs don't
leak into the pairs list.

No visible behaviour change — template doesn't consume the new key yet.

## Task 2: Template markup — popover shells + Apply button + json_script embed

**Files:**
- Modify: `core/templates/core/report.html` (extend existing `.filter-pill-strip` block, add popover panels + Apply button + json_script, all in the `d-print-none` region at the top of the page)

**Step 2.1: Replace the existing filter-pill strip (lines 33-50)**

Find the existing strip:

```django
{# === FILTER PILLS === #}
<div class="filter-pill-strip d-flex flex-wrap gap-2 mb-4 d-print-none">
    <span class="filter-pill">
        <i class="fas fa-calendar me-1"></i>{{ start_date|date:"d M Y" }} &ndash; {{ end_date|date:"d M Y" }}
    </span>
    <span class="filter-pill">
        <i class="fas fa-folder me-1"></i>{{ project_name }}
        {% if selected_project_ids %}
        <a href="?{{ query_string_without_project|default:query_string }}" class="filter-pill__x" aria-label="Clear project filter">&times;</a>
        {% endif %}
    </span>
    <span class="filter-pill">
        <i class="fas fa-users me-1"></i>{{ team_name }}
        {% if selected_team_ids %}
        <a href="?{{ query_string_without_team|default:query_string }}" class="filter-pill__x" aria-label="Clear team filter">&times;</a>
        {% endif %}
    </span>
</div>
```

Replace with the interactive version:

```django
{# === FILTER PILLS (interactive — pill-as-dropdown) === #}
{# Each pill is a clickable button that opens an inline popover with the #}
{# relevant editor. The Apply button appears only when at least one pill #}
{# has uncommitted changes. See the JS module lower in this file. #}
<div class="filter-pill-strip d-flex flex-wrap gap-2 mb-4 d-print-none" id="filter-pill-strip">

    {# --- Date pill --- #}

```

**Step 2.2: Check syntax**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py check
```

Expected: only pre-existing `staticfiles.W004` warning; no template errors.

**Step 2.3: Sanity-check the page still renders**

```bash
curl -s -o /dev/null -w "%{http_code}\n" http://localhost:8000/report/
```

Expected: `302` (login redirect; page renders OK). Open the report page in the browser — pills should be visible with chevrons, though clicking them does nothing yet (no JS). The popovers sit below each pill with `hidden` attribute — they should NOT be visible.

**Step 2.4: Commit**

```bash
git add core/templates/core/report.html
git commit -m "$(cat <<'EOF'
Template: interactive filter-pill markup + popover shells

Replaces the three static filter pills with clickable buttons and
inline popover shells below each one. Popovers remain hidden by
default (hidden attribute) — the JS module in Task 4 will wire up
open/close, dirty state, and Apply behaviour.

Structure per pill:
- .filter-pill-wrap (position-relative container)
  - <button class="filter-pill filter-pill--editable" data-filter="...">
    with chevron indicating clickability
  - <a class="filter-pill__x"> (existing × clear-filter link, preserved)
  - .filter-popover (the editable widget — date picker for the Date
    pill, Choices.js multi-select for Projects/Teams pills)

Apply + Reset buttons sit in .apply-filters-group at the right end,
initially hidden. A <div id="filter-toast-container"> is pre-placed
for the cross-filter auto-removal notices.

Three json_script blocks embed the data the JS needs:
- projectTeamPairs: (project_id, team_id) pairs for cross-filter
- urlSelectedProjectIds / urlSelectedTeamIds: current URL state for
  dirty diffing + reset

No visible behaviour change yet (no CSS, no JS). Page renders same
as before until Tasks 3-4 light it up.

## Task 3: CSS — pill-editable, pill-dirty, popover, apply-button, toast

**Files:**
- Modify: `static/css/custom.css` (append to end of file)

**Step 3.1: Append the new CSS block**

Append this at the end of `static/css/custom.css`:

```css
/* === Inline Filters (pill-as-dropdown) on the report page === */
/*
   Layered on top of the existing .filter-pill rules (lines ~1496–1524).
   Three components:
     1. .filter-pill--editable: pointer cursor, hover tint, chevron
     2. .filter-pill--dirty: accent outline + small pulsing dot when uncommitted
     3. .filter-popover: absolute-positioned dropdown beneath the pill
     4. .apply-filters-group: slide-in Apply/Reset buttons when any pill dirty
     5. .filter-toast-container: cross-filter auto-removal notices
*/

/* --- Wrapper keeps the popover anchored to its pill --- */
.filter-pill-wrap {
    display: inline-flex;
    align-items: center;
}

/* --- Editable pill: button, cursor, hover state, chevron --- */
.filter-pill--editable {
    cursor: pointer;
    border: 1px solid var(--border-default);
    background: var(--bg-inset);
    color: var(--text-primary);
    transition: background-color 120ms, border-color 120ms, box-shadow 120ms;

    border-color: var(--accent);
    box-shadow: 0 0 0 2px rgba(232, 133, 26, 0.18);
}
.filter-pill--dirty::before {
    content: '';
    display: inline-block;
    width: 6px;
    height: 6px;
    border-radius: 50%;

    padding: 0;
}
.filter-popover[hidden] {
    display: none;
}
.filter-popover__body {
    padding: 1rem;
}

    background: var(--bg-inset);
    border-radius: 0 0 0.5rem 0.5rem;
}

/* --- Mobile: popovers stretch full-width below the pill strip --- */
@media (max-width: 576px) {
    .filter-popover {
        position: fixed;
        top: auto;
        bottom: 0;

        border-radius: 0.5rem 0.5rem 0 0;
        z-index: 1050;
    }
}

/* --- Apply / Reset button group --- */
.apply-filters-group {
    display: flex;
    align-items: center;
    animation: apply-slide-in 180ms ease-out;
}
.apply-filters-group[hidden] {
    display: none;
}
@keyframes apply-slide-in {
    from { opacity: 0; transform: translateX(8px); }
    to   { opacity: 1; transform: translateX(0); }
}

/* --- Toast container for cross-filter auto-remove notices --- */
.filter-toast-container {
    position: fixed;
    top: 4.5rem;  /* below topbar */
    right: 1rem;
    z-index: 1060;
    display: flex;
    flex-direction: column;
    gap: 0.5rem;
    pointer-events: none;
    max-width: 320px;
}
.filter-toast {
    background: var(--bg-card);
    color: var(--text-primary);
    border: 1px solid var(--accent);
    border-left: 4px solid var(--accent);
    border-radius: 0.375rem;
    padding: 0.75rem 1rem;
    font-size: 0.875rem;
    box-shadow: 0 4px 12px rgba(0, 0, 0, 0.22);
    animation: filter-toast-in 200ms ease-out;
    pointer-events: auto;
}
.filter-toast--exiting {
    animation: filter-toast-out 200ms ease-in forwards;
}
@keyframes filter-toast-in {
    from { opacity: 0; transform: translateX(12px); }
    to   { opacity: 1; transform: translateX(0); }
}
@keyframes filter-toast-out {
    to { opacity: 0; transform: translateX(12px); }
}
```

**Step 3.2: Verify the CSS applies**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py check 2>&1 | tail -3
```

Expected: only the pre-existing `staticfiles.W004` warning.

Manual browser check: open the report page, hover a pill — cursor should show pointer + subtle background tint + orange border. Chevron present. Popover still hidden (no JS yet to open it).

**Step 3.3: Commit**

```bash
git add static/css/custom.css
git commit -m "$(cat <<'EOF'
CSS: inline-filter pill-dropdown styling

Adds five new style components beneath the existing .filter-pill rules:

1. .filter-pill--editable   — pointer cursor, hover tint, chevron rotation
2. .filter-pill--dirty      — accent outline + pulsing orange dot
3. .filter-popover          — absolute-positioned dropdown with shadow;
                               on mobile (<576px) anchors to bottom of
                               viewport full-width
4. .apply-filters-group     — slide-in animation on the Apply/Reset buttons
5. .filter-toast-container  — fixed top-right stack for cross-filter
                               auto-remove notices; slide-in/out animations

All colours via existing design tokens (--accent, --bg-card,
--text-primary, --border-default, --bg-inset) so dark + light themes
work automatically. z-index layering (popover 1040, toast 1060) stays
below Bootstrap modals (1055+) to avoid stacking conflicts.

## Task 4: JS — the pill-popover interactive module

The heart of the feature. One scoped IIFE appended to `report.html` that handles:
- Open / close popovers (click pill, click outside, Esc)
- Initialise Choices.js on the two multi-selects the first time their popover opens
- Date-mode toggle (Month vs Custom) inside the date popover
- Track pending state per pill; compare against URL state; update `.filter-pill--dirty` + Apply button visibility
- Cross-filter (Team↔Project) with auto-remove + toast
- Apply → submit via `window.location`
- Reset → revert all pills

**Files:**
- Modify: `core/templates/core/report.html` (append `<script>` block at the end, inside `{% block content %}` or before `{% endblock %}`)

**Step 4.1: Locate the insertion point**

Find the final `{% endblock %}` (or `{% endblock content %}`) in `core/templates/core/report.html`. Insert the script block IMMEDIATELY before it.

**Step 4.2: Append the JS module**

```django
{# === INLINE FILTERS — PILL POPOVER MODULE === #}
{# Scoped IIFE; runs once on DOMContentLoaded. Manages popover open/close, #}
{# dirty state, cross-filter, Apply submission. XSS-safe: createElement + #}
{# textContent only (no innerHTML with user data). Matches CLAUDE.md pattern. #}
<script>
document.addEventListener('DOMContentLoaded', function() {
    // --- Bail if Choices.js isn't loaded (shouldn't happen since admin-only page loads it) ---
    if (typeof Choices === 'undefined') {
        console.warn('[inline-filters] Choices.js not loaded; pills will not enhance');

    // URL state (strings from template) — cast to ints for comparison
    function toIntArr(s) { return (JSON.parse(s || '[]') || []).map(function(v) { return parseInt(v, 10); }).filter(function(n) { return !isNaN(n); }); }
    var urlProjects = toIntArr(urlProjectsEl && urlProjectsEl.textContent);
    var urlTeams = toIntArr(urlTeamsEl && urlTeamsEl.textContent);

    // --- Cross-filter lookup indices ---

JS: pill-popover interactive module for inline filters

One scoped IIFE that wires up the three filter pills into an
interactive, state-managed UI:

- Click pill -> open popover (lazy-inits Choices.js on first open)
- Click outside / Esc / other pill -> close
- OK commits popover's local edits into pending state; dirty pills
  get orange outline + pulsing dot; Apply button slides in at the
  right end of the strip
- Cross-filter: picking projects auto-removes now-invalid teams
  with toast notice ("Removed Team X — no logs on selected projects"),
  and vice versa. Scope = entire history.
- Apply -> rebuilds querystring from pending state + navigates
  (full page reload, same URL scheme as the retired modal)
- Reset -> reverts all pills to URL-current values

XSS-safe throughout: textContent and createElement; no innerHTML with
user data. Matches the pattern in base.html's work-log-payroll modal
from the previous feature.

Graceful fallback: if Choices.js CDN fails to load, the module bails
early with a console warning; native <select multiple> still works
inside the popovers.

### 🛑 CHECKPOINT 1 — all pill interactions demoable

Konrad should open `/report/` in the browser (hard refresh) and walk through:

1. Click the date pill → popover opens with month/custom toggle + pickers
2. Change from-month → click OK → pill shows new range, Apply button appears, pill has orange dirty outline
3. Click Apply → URL updates → report re-renders with new filters
4. Click projects pill → popover with Choices.js multi-select → pick 2 projects → OK → pill updates to "Project A + 1 more"
5. Click teams pill → popover → if a project is already selected, teams that haven't worked on it are disabled; pick a valid team → OK
6. Intentionally: pick a project, then add a team that doesn't match → on OK, that team gets auto-removed with a toast
7. Click the × on a pill (existing behaviour) → filter clears via full page reload
8. Click Reset when dirty → all pills revert, Apply disappears
9. Esc key → any open popover closes
10. Modal still works via the "Generate Report" button on the dashboard + "New Report" button on the report page (Task 5 retires them)

Await approval before Task 5 (modal retirement — destructive).

---

## Task 5: Retire the modal

**Files:**
- Modify: `core/templates/core/index.html` (line 187 — change button to plain link; line 605 — remove include)
- Modify: `core/templates/core/report.html` (lines 20-23 delete header "New Report" button; lines 387-389 delete bottom "New Report" button; line 400 remove include)
- Delete: `core/templates/core/_report_config_modal.html`
- Modify: `core/views.py` (lines 434-435 remove from `index()` context; lines 2395-2404 remove from `generate_report` context)

**Step 5.1: Update `core/templates/core/index.html`**

Find around line 187 (Quick Actions "Generate Report"):

```django
<a href="#" class="quick-action" data-bs-toggle="modal" data-bs-target="#reportConfigModal">
    <i class="fas fa-file-alt"></i>
    <span>Generate Report</span>
</a>
```

Replace with a plain link to `/report/` pre-loaded with the current month:

```django
{# Plain link: pills on the report page are the new-report interface. #}
<a href="{% url 'generate_report' %}?from_month={% now 'Y-m' %}&to_month={% now 'Y-m' %}" class="quick-action">
    <i class="fas fa-file-alt"></i>
    <span>Generate Report</span>
</a>
```

Then find line 605 and delete the `{% include 'core/_report_config_modal.html' %}` line entirely.

**Step 5.2: Update `core/templates/core/report.html`**

Delete the header "New Report" button block (around lines 20-23):

```django
<!-- New Report: opens the same config modal as the Dashboard -->
<button type="button" class="btn btn-primary shadow-sm" data-bs-toggle="modal" data-bs-target="#reportConfigModal">
    <i class="fas fa-plus me-1"></i>New Report
</button>
```

Delete the bottom "New Report" button block (around lines 387-389):

```django
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#reportConfigModal">
    <i class="fas fa-plus me-1"></i>New Report
</button>
```

Delete the include line (around line 400):

```django
{% include 'core/_report_config_modal.html' %}
```

(Also delete any comment block immediately above that include, if it only refers to the modal.)

**Step 5.3: Delete the modal template file**

```bash
git rm core/templates/core/_report_config_modal.html
```

**Step 5.4: Update `core/views.py` — remove `selected_*_ids` threading**

In `index()` (around line 434):

Find:
```python
            'selected_project_ids': [],
            'selected_team_ids': [],
```

Delete these two lines.

In `generate_report` (around line 2395-2404):

Find the whole block:
```python
    # Pass projects and teams so the "New Report" modal's dropdowns can
    # populate (same lists the Dashboard modal uses)
    context['projects'] = Project.objects.all().order_by('name')
    context['teams'] = Team.objects.all().order_by('name')
    # For the modal's <select multiple> pre-selection: stringify the IDs so
    # the template's `{% if p.id|stringformat:"s" in selected_project_ids %}`
    # comparison works (Django templates compare strings to strings).
    context['selected_project_ids'] = [str(p) for p in (project_ids or [])]
    context['selected_team_ids'] = [str(t) for t in (team_ids or [])]
```

**Keep** the `projects` / `teams` context keys (the pills' popovers still use them to render `<option>` lists). But **remove** the `selected_project_ids` / `selected_team_ids` stringify block — the JS reads those from `json_script` tags which the template still needs. Wait — the pills DO use `selected_project_ids` / `selected_team_ids` for pre-selection. So these stay!

Actually, re-read Task 2's markup: the popover `<option>` tags use `{% if p.id|stringformat:"s" in selected_project_ids %} selected{% endif %}`, and the json_script tag emits `{{ selected_project_ids|json_script:"urlSelectedProjectIds" }}`. Both references are in Task 2's markup — so **these context keys stay**.

**Correction**: do NOT remove the `selected_project_ids` / `selected_team_ids` context keys. The inline-filters feature still uses them.

Only the **modal itself** is deleted; the data it consumed is still needed by the pill markup.

So Step 5.4 reduces to: **no change to `core/views.py`**. All backend context stays.

**Step 5.5: Run tests + manage.py check**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py test core.tests -v 0 2>&1 | tail -5
USE_SQLITE=true DJANGO_DEBUG=true python manage.py check
```

Expected: `Ran 44 tests ... OK`; only the `node_modules` warning.

**Step 5.6: Verify no dangling references to the deleted modal**

```bash
grep -rn "reportConfigModal\|_report_config_modal" core/templates/ core/views.py
```

Expected: **zero hits**. If any remain, delete them.

**Step 5.7: Commit**

```bash
git add core/templates/core/index.html core/templates/core/report.html
git commit -m "$(cat <<'EOF'
Retire _report_config_modal.html — pills are the new-report interface

- Dashboard 'Generate Report' button: modal trigger -> plain link
  to /report/?from_month=<current>&to_month=<current>
- Report page 'New Report' buttons (both header + bottom action bar):
  deleted (the pills replace them)
- _report_config_modal.html: deleted
- No backend changes — selected_project_ids / selected_team_ids
  context keys are still used by the pill popovers for pre-selection
  (just not by the retired modal)

grep -rn 'reportConfigModal' core/templates/ core/views.py returns 0.

## Task 6: Final QA + mark shipped

**Files:**
- Modify: `docs/plans/2026-04-23-inline-filters-design.md` (append "Shipped" block)

**Step 6.1: Manual QA matrix**

As admin, walk through:

| Flow | Expected |
|---|---|
| `/report/` no filters | Pills show current-month range + "All Projects" + "All Teams"; no Apply button; no × buttons |
| Click date pill → change month → OK → Apply | URL has `?from_month=...&to_month=...`; report re-renders |
| Click projects pill → pick 2 → OK → teams popover | Teams not linked to either project are disabled in the dropdown |
| Pick a team not linked to selected projects → OK | Team gets auto-removed with toast "Removed Team X — no logs on selected projects" |
| Reset button (when dirty) | All pills revert, Apply disappears |
| Esc key when popover open | Popover closes |
| Existing × buttons on pills | Still clear individual filters via full page reload |
| Click dashboard "Generate Report" card | Navigates directly to `/report/?from_month=<current>&to_month=<current>` — no modal |
| `grep -rn 'reportConfigModal' core/templates/` | Zero hits |
| Supervisor user hits `/report/` | 403 (unchanged) |
| PDF download with any filter | Mirrors current filter state (unchanged) |
| Phone viewport | Popovers dock to bottom of viewport full-width |

**Step 6.2: Full test run**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py test core.tests -v 0 2>&1 | tail -5
```

Expected: `Ran 44 tests ... OK`.

**Step 6.3: Django system check + migrations dry-run**

```bash
USE_SQLITE=true DJANGO_DEBUG=true python manage.py check
USE_SQLITE=true DJANGO_DEBUG=true python manage.py makemigrations --dry-run
```

Expected: only `staticfiles.W004`; "No changes detected".

**Step 6.4: Append "Shipped" block to the design doc**

Append to `docs/plans/2026-04-23-inline-filters-design.md`:

```markdown
---

## Shipped — 23 Apr 2026

**Commits:** 30d0991 (design) through the Task 6 shipped commit.
**Plan:** `docs/plans/2026-04-23-inline-filters-plan.md`
**Tests:** 42 → 44 (2 new — InlineFiltersPairsContextTests covering
the `project_team_pairs_json` context key + NULL-team exclusion).

**QA outcome:** 44/44 tests pass. `manage.py check` clean.
`makemigrations --dry-run` reports no changes. All 10 manual QA
flows green. Cross-filter auto-remove + toast behaviour verified.
_report_config_modal.html fully retired; grep confirms no dangling
references.

**Deferred / out of scope (revisit if requested):**
- AJAX partial re-render (still full page reload on Apply)
- "Save this filter set" / named filter presets
- Permissive cross-filter variant (strict was chosen)
- Date-range-scoped cross-filter (entire history was chosen)

**Notable decisions made during implementation:**
- Modal `selected_project_ids` / `selected_team_ids` context keys
  were KEPT (not removed as the design initially suggested) because
  the pill popovers still use them for pre-selecting the Choices.js
  `<option>` tags and for URL-diff initialisation via json_script.
- Choices.js re-init on cross-filter change (destroy + reinstantiate)
  is wasteful but the simplest way to reflect `<option disabled>`
  changes; acceptable at FoxFitt's scale (≤10 projects, ≤10 teams).
```

**Step 6.5: Commit**

```bash
git add docs/plans/2026-04-23-inline-filters-design.md
git commit -m "Docs: mark Inline Filters feature as shipped (23 Apr 2026)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>"

### 🛑 CHECKPOINT 2 — ship

Final demo: all pills work, modal gone, tests green, PDF still respects filters.

**On approval → single batched push** of all 6 commits (plus the two design-doc commits from earlier — 30d0991 inline-filters-design + 12edafa adjustments-tab-design). The adjustments-tab design doc rides along since it was committed locally in the same brainstorm session.

Gemini deploy prompt (CSS change → collectstatic mandatory):

```bash
git fetch github && git pull github ai-dev && \
  python3 manage.py collectstatic --noinput && \
  sudo systemctl restart django-dev.service
```

---

## Out of scope (not in this plan)

- Inline filter persistence across browser tabs (a URL-sharing improvement; URLs already bookmarkable)
- Filter-chip sort order preference
- Keyboard navigation between pills (Tab works via native button focus)
- Adjustments tab (separate plan after this ships)

---

Plan complete and saved to `docs/plans/2026-04-23-inline-filters-plan.md`. Two execution options:

**1. Subagent-Driven (this session)** — I dispatch a fresh subagent per task, review between tasks, fast iteration.

**2. Parallel Session (separate)** — Open a new Claude Code session with `superpowers:executing-plans`, batch execution.

**Which approach?**
