Summary

Complete analytics feature: JSON export across all surfaces (TUI, chat, web, VS Code, MCP, API) with comprehensive code quality refactoring.

User Features:

  • Export analytics to JSON: TUI ([e]), chat (/analytics export [path]), web (download button), VS Code command
  • Analytics modal in TUI with keyboard navigation ([i] to open, [r] refresh, [e] export, [esc] close)
  • Analytics page in web with time range selector (7/14/30/90 days) and KPI cards
  • Cost tracking removed (ACP field unstable/optional across backends)

Code Quality:

  • Deduplicated format_duration() and format_percentage() — single source across Python/TS
  • Unified API client method signatures (VS Code now matches web pattern)
  • Fixed chat export parsing (handles paths correctly)
  • Resolved circular import in TUI analytics modal

UX & Accessibility:

  • Export button smart disable (only during export, not load)
  • Added aria-labels to export button, chart sections, empty states
  • Semantic element, role="status" for empty states
  • API responses consistent (export endpoint returns same structure when no project)

Test Plan

  • All 396 Python tests passing (2 pre-existing MCP failures unrelated to analytics)
  • All 145 web component tests passing
  • TypeScript checks pass (web + VS Code)
  • Ruff lint + format pass
  • Manual: TUI [i] opens analytics modal, [e] exports to JSON
  • Manual: Web export button downloads JSON with current time range
  • Manual: Chat /analytics export /tmp/test.json writes file
  • Manual: VS Code command opens save dialog and writes JSON

Users who ran beta or feature-branch builds could end up with an
alembic revision that no longer exists in the migration chain after
upgrading. This crashed the app on startup, requiring manual
`alembic stamp` intervention.

Since all migrations are idempotent (they check column/table existence
before acting), it is safe to stamp back to the base revision and let
the upgrade re-apply. Replace the RuntimeError with a logged warning
and automatic stamp-to-base recovery.

…olumn

Remove the grid layout that caused proportion imbalance between
SettingsPanel and the smaller sidebar cards. All sections now stack
in a single centered column (max-w-2xl): SettingsPanel, AgentPicker,
ConnectionCard, PreflightChecks. Works identically on desktop and
mobile with zero wasted space.

Cost data is unreliable (ACP cost field is UNSTABLE, most backends don't
report it) — remove cost from analytics views while keeping DB fields for
future use. Replace the cost KPI/charts with a duration-by-backend chart.

Surface analytics across all platforms:
- MCP: analytics_backend_stats and analytics_session_timeline tools
- TUI: AnalyticsModal screen accessible from kanban
- Chat: /analytics slash command with Rich table output
- VS Code: kagan.analytics.show command with markdown report
- API: cost-summary route removed, backend-stats and session-timeline remain

Co-Authored-By: Claude Opus 4.6 <[email protected]>
Add export capability to analytics: core export() method bundles backend
stats + session timeline into a single JSON payload. Wired into API
(GET /api/analytics/export), MCP tool, TUI ([e] keybinding), chat CLI
(/analytics export [path]), web (download button), and VS Code command.

…and UX

Code Quality & Maintainability:
- Extract shared format_duration() and format_percentage() to core._formatting
- Replace 4 duplicate implementations (web, vscode, cli, tui) with single source
- Fix circular import in tui/screens/analytics.py (removed module-level KaganApp import)

API Design:
- Unify VS Code client methods: getSessionTimeline/getAnalyticsExport now use params object
- Consistent with web API client pattern and HTTP query param style
- Fix chat export parsing: handle "/analytics export /path/to/file" correctly

UX & Accessibility:
- Web export button: only disabled during export operation, not during load
- Add aria-labels to export button, chart sections, empty states
- Use semantic <header> element for analytics page header
- Add role="status" to empty state divs for screen reader announcements

API Response Consistency:
- Export endpoint now returns same structure when no project (empty arrays, period_days)
- Prevents consumer code from special-casing the "no project" path

Greptile Summary

This PR completes the analytics feature by adding JSON export across all surfaces (TUI, chat, web, VS Code, MCP, API) and refactors the Tasks class to consolidate module-level functions. The implementation is thorough but ships with a P0 crash in the TUI modal and a P1 data accuracy issue in the web KPI card.

  • P0 — TUI analytics modal always crashes with data present: format_duration and format_percentage are imported inside if TYPE_CHECKING: in src/kagan/tui/screens/analytics.py (lines 15–16). These are called at runtime in _build_backend_table() / _build_timeline_summary(), producing NameError for any project that has session data. Move the import outside the TYPE_CHECKING block (or defer it inside the functions).
  • P1 — avgDuration KPI denominator is wrong: analytics-page.tsx computes the weighted average by dividing by totalSessions (all backends) while treating null-duration backends as 0s — skewing the displayed mean downward when some backends lack timing data.
  • P1 — _db.py migration stamping: The new error-recovery path stamps an unknown revision to _HEAD_REVISION while logging "stamping to base and re-applying migrations"; this is self-contradictory and risks making Alembic believe the schema is at HEAD while no migrations run.

Confidence Score: 4/5

Not safe to merge as-is — the TUI analytics modal will crash with a NameError for any project that has session data.

A P0 (NameError at runtime in the TUI modal) and two P1 issues (avgDuration wrong KPI value; _db.py silent schema stamp with misleading log) must be resolved. The rest of the PR — Tasks class consolidation, server client refactoring, web analytics page, chat/MCP/VS Code surfaces — is well-implemented and low risk.

src/kagan/tui/screens/analytics.py (P0 import bug), src/kagan/core/_db.py (P1 migration stamping), packages/web/src/pages/analytics-page.tsx (P1 avgDuration denominator)

Important Files Changed

Filename Overview
src/kagan/tui/screens/analytics.py New TUI analytics modal — critical P0 bug: format_duration and format_percentage are placed under TYPE_CHECKING, causing NameError at runtime whenever the modal renders data
packages/web/src/pages/analytics-page.tsx New analytics page with KPI cards, charts, and JSON export; avgDuration KPI uses incorrect denominator when some backends have null duration, skewing the weighted average displayed to users
src/kagan/core/_db.py Silences RuntimeError on unknown Alembic revision by stamping to HEAD_REVISION; log message says 'stamping to base' but code stamps to HEAD, risking silent schema incompatibility
src/kagan/core/_analytics.py New Analytics class with backend_stats, session_timeline, and export methods using correct _db_async pattern; SQLite-specific julianday usage is acceptable for this project
src/kagan/core/_tasks.py Large refactoring: module-level task functions removed and inlined into the Tasks class; logic is preserved with no functional changes, improving encapsulation
packages/vscode/src/api/types.ts EVENT_TYPE const removed, WireEvent.type widened to plain string — violates CLAUDE.md convention requiring event strings to come from typed constants
src/kagan/server/client/_local_client.py LocalClient simplified by inlining UnixSocketClient and adding aenter/aexit; base.py (KaganClient ABC) removed; clean consolidation with no functional regressions
packages/vscode/src/commands/analytics.ts New VS Code analytics commands (show/export); formatDuration and formatPercentage duplicated locally rather than shared with web format.ts

Comment:
**`format_duration`/`format_percentage` under `TYPE_CHECKING` causes `NameError` at runtime**

`format_duration` and `format_percentage` are imported inside the `TYPE_CHECKING` block, so they are **not available at runtime**. Both `_build_backend_table()` and `_build_timeline_summary()` call them directly — every user who opens the analytics modal with existing session data will get an unhandled `NameError` when `_load_data()` fires. The modal is permanently broken for non-empty projects.

```suggestion
if TYPE_CHECKING:
    from textual.app import ComposeResult

from kagan.core._formatting import format_duration, format_percentage
```

If the circular-import concern is still live, move the import inside `_build_backend_table` and `_build_timeline_summary` instead.

How can I resolve this? If you propose a fix, please make it concise.

Comment:
**Incorrect denominator for weighted average duration**

`avgDuration` divides by `totalSessions` (all backends), but the numerator uses `(b.avg_duration_seconds ?? 0) * b.count` — null-duration backends contribute 0 seconds, silently pulling the weighted mean down. For example, with Backend A (count=10, avg=60s) and Backend B (count=5, avg=null), the card shows 40s instead of the correct 60s. The subtitle "Weighted by session count" makes the incorrect value misleading.

The denominator should only sum counts from backends that actually have duration data:

```suggestion
  const sessionsWithDuration = backendStats
    .filter((b) => b.avg_duration_seconds != null)
    .reduce((sum, b) => sum + b.count, 0);
  const avgDuration =
    sessionsWithDuration > 0
      ? backendStats.reduce((sum, b) => sum + (b.avg_duration_seconds ?? 0) * b.count, 0) /
        sessionsWithDuration
      : null;

The format_duration and format_percentage functions were in a TYPE_CHECKING
block but were used at runtime in the analytics modal methods, causing TC004
ruff violations. Moving them to regular imports fixes the lint errors.

KaganApp remains in TYPE_CHECKING since it's only used in type annotations.

…tamping, event types, and format dedup

- Fix avgDuration KPI calculation in analytics-page.tsx: only count sessions from backends with duration data in denominator
- Fix _db.py: stamp to 'base' instead of HEAD_REVISION so subsequent upgrades apply all migrations
- Restore EVENT_TYPE constant in VS Code types.ts per CLAUDE.md convention
- Create packages/vscode/src/lib/format.ts to deduplicate formatDuration and formatPercentage

P1 fixes:
- avgDuration now correctly weighted only by backends with actual timing data
- Migration recovery now properly applies from base, not stamping to HEAD
- EVENT_TYPE constant prevents hand-typed event strings in providers
- VS Code format utilities now shared with consistent implementations
