* feat(me/stats): per-analyst Stats dashboard with 4 tabs
New /me/stats page shows the calling user's own analytics across
four tabs, lazy-loaded per activation:
- **Sessions** — paginated usage_session_summary join with a
filesystem scan of un-processed JSONL (mirrors admin
list_user_sessions shape). v44 token columns aggregated per row.
- **Tokens** — daily series (default 30 days), by-model breakdown
(lifetime), top-10 biggest sessions, lifetime totals. Single
CTE per sub-query against per-user partition (idx_usage_session_user).
- **Data access** — audit_log rows where action LIKE 'query.%' for
the caller. Covers query.local / query.hybrid / query.remote /
query.internal. Cursor-paginated on (timestamp, id).
- **Sync activity** — audit_log rows where action is sync.* or
manifest.* for the caller, plus users.last_pull_at for the
header. Per-pull history now persists thanks to the new
manifest.fetch audit row.
Backend: app/api/me_stats.py — single APIRouter at /api/me/stats/*,
four GET endpoints, all gated by get_current_user (server-side
caller scope; the page route itself only renders the shell).
Frontend: app/web/templates/me_stats.html — tab bar + 4 panels,
plain JS lazy-loads each panel's endpoint on first activation,
caches per-tab so switching back doesn't refetch. Small SVG bar
chart on Tokens tab (no external charting dep). 'Stats' link
added to _app_header.html primary nav between 'Data Packages'
and the Admin dropdown.
Side change in app/api/sync.py: /api/sync/manifest now emits a
manifest.fetch audit_log row alongside the existing
users.last_pull_at bump. The column UPDATE only retains the
most recent timestamp; per-pull history needs an audit row.
client_kind='api' for the manifest endpoint (vs. 'web' which
the audit-read deduper uses for AC reads), so the Sync tab can
distinguish CLI pulls from browser-driven manifest peeks.
7 new tests in tests/test_me_stats.py:
- sessions endpoint caller-scope isolation (user A doesn't see B)
- sessions pagination
- tokens empty-user zero shape
- tokens aggregation across daily window + by_model + top + totals
- queries endpoint filters to action LIKE 'query.%' + caller scope
- sync endpoint surfaces both manifest.fetch and sync.trigger
- manifest endpoint writes the manifest.fetch audit row
* ui(me/stats): widen page to 1400px via main.main escape
Default base.html .container wraps content at max-width 800px. Stats
tables (by-model + top-sessions: 6 columns each) felt cramped at that
width — same constraint dashboard.html escapes via the {% block layout %}
override pattern. Mirror that here: render <main class="main"> and
bump .stats-page max-width to 1400px so the 6-column tables breathe
without going edge-to-edge on wide monitors.
* ui(me/stats): narrow from 1400px to 1280px to match /home
/home isn't actually .container's default 800px — style-custom.css
has a body:has(.home-mock) .container { max-width: 1280px } override
that widens it. 1280px is the shared 'wide content' width across the
codebase (top-nav header + /home + dashboard all use it).
Bumping me_stats from 1400px to 1280px so the Stats page reads as
'same chrome' instead of distinctly wider than its sibling pages.
