Parent RFC: Personal AI Assistant Log Aggregator (2026-04-25)

Sibling tasks:
lethe-server.md (#1, ✓ verified)lethe-collector-claude-code.md (#2, deferred)lethe-search-and-opencode.md (#3, deferred)lethe-web-ui-aggregates.md (#5, deferred — Projects/Stats endpoints + screens)lethe-web-ui-palette-savedsearch.md (#6, deferred — full ⌘K + saved searches)lethe-web-ui-settings-display.md (#7, deferred — Settings → Display)lethe-web-ui-search.md (#8, blocked on #3)lethe-web-ui-health-sources.md (#9, blocked on #2)Stand up the Lethe web UI: a single-page React app served by the lethe binary, providing a usable browse-and-read experience over the existing /api/v1/sessions surface. This is the foundation that follow-on tasks build on (aggregates, palette, settings, search, health). In scope: project skeleton, build pipeline, embed/serve, theming primitives, Home, Session view. Out of scope: Projects, Stats, Search, Health, Settings, ⌘K palette beyond a stub, saved searches.
Stack: React 18 + TypeScript + Vite + TanStack Router + TanStack Query, vanilla CSS using the tokens shipped in the handoff's prototype.css. (React over alternatives because the handoff is a React prototype — porting JSX directly is the cheapest route to fidelity.)
Layout: source at web/ (sibling to cmd/, internal/); web/dist/ is git-ignored; production embeds via //go:embed all:dist/* from internal/server/web/embed.go and serves the SPA as a fallback under the unauthed mux. /api/v1 stays auth-gated; the SPA shell loads even if unauthenticated, and a 401 from any data fetch flips the UI into an auth-error state.
Dev: just web-dev starts vite at :5173 with a proxy to 127.0.0.1:18888 for /api/v1, /healthz, /readyz, /metrics. The proxy injects Remote-User: bigbes on every outbound request so forward-auth passes without a real reverse proxy. Go code is not modified for dev auth.
| Path | Screen |
|---|---|
/ |
Home (recent sessions, real data) |
/session/:tool/:host/:id |
Session view (turn list aside + transcript, real data) |
/projects, /stats, /health, /settings |
Stub: TopBar tab is functional, screen renders a small "coming in a later task" EmptyState card |
/search |
Stub (palette's synthetic SEARCH for "<q>" row routes here) |
| anything else | 404 (the prototype's EmptyState) |
Stubs ship to keep the shell coherent (TopBar tabs and g h/p/s/i keybindings all "work" — they navigate). They're cheap and avoid TopBar dead-clicks.
GET /api/v1/sessions response gains five fields per row, all derivable from the current schema:
| Field | SQL |
|---|---|
summary |
first user turn's content, truncated to 200 chars |
turn_count |
COUNT(*) over turns scoped to the session |
tokens_in_total, tokens_out_total |
SUM(tokens_in), SUM(tokens_out) over the same scope |
model |
latest turn's model (ORDER BY seq DESC LIMIT 1) |
Implemented with a single SQL using correlated subqueries or a derived join, in internal/domain/session/repository.go. Repository tests cover each aggregate. No wire-type changes, no schema changes, no removed fields — the response stays a strict superset.
branch and has_error (in the handoff's Session TS type) are deferred — neither is in the schema; will land in a future task that introduces them.

internal/domain/session/repository.go:97-107 (modify) — Session struct gains five fields, all with matching db and json tags:
Summary string (json summary)TurnCount int64 (json turn_count)TokensInTotal int64 (json tokens_in_total)TokensOutTotal int64 (json tokens_out_total)Model *string (json model,omitempty)internal/domain/session/repository.go:176-189 (modify) — sessionSelectColumns stays as-is for Get path (which uses SessionWithTurns and computes nothing).

Decide during execute; default to the custom renderer unless the prototype's session screenshots show full markdown rendering (which they do — code blocks, lists, headings). Likely outcome: ship react-markdown.LIMIT 40 this is fine; on LIMIT 200 it could matter. If EXPLAIN QUERY PLAN shows table scans on turns, add a covering index (owner, tool, host, session_id, role, seq) in a sibling commit. Not blocking the phase./api/v1. The embed in Phase 3 means a revert there leaves the binary serving 404 on / — the current behavior — so it's a no-op for API users.Restating from Design: only GET /api/v1/sessions changes shape, additively. The five new fields (summary, turn_count, tokens_in_total, tokens_out_total, model) are added; nothing is removed or renamed. No client today depends on the response shape (only consumer is the integration test, which we update). No schema migrations; no wire-type changes; no config-key changes.

Notes:
g-leader keyboard chord could not be smoke-tested via Chrome DevTools MCP: each press_key call carries hundreds of milliseconds of MCP serialization latency, exceeding the controller's 800 ms g-pending timeout. Verified by running an isolated minimal chord handler in the page that reproduced the same null result. Production code is unaffected (real human typing is sub-100ms between keys); unit tests in web/src/lib/keyboard.test.ts cover the timing logic with vi.useFakeTimers()./session/$tool/$host/<encoded-composite> because the Link in SessionsTable passes params.id = session.id (which is the full composite ${tool}/${host}/${session_id}). Phase 6's useSession adapter splits the composite back, so the Session view loads correctly. Fix is a one-liner (pass the bare session_id instead) — deferred as a follow-up since it's cosmetic, not functional.Session aggregate fields on the Get endpoint return zeros: GET /api/v1/sessions/{tool}/{host}/{id} reuses the Session Go struct via SessionWithTurns, so the new summary, turn_count, tokens_in_total, tokens_out_total fields appear in JSON as zero values. By design (Plan 1.2 said the Get path is unchanged); the SPA's Session view computes from turns[] directly, so this is invisible to the UI. Worth flagging because a future API consumer reading summary from a Get response would see an empty string.go test ./... walks web/node_modules/flatted/golang/pkg/flatted: a stray Go package shipped inside an npm dep. Reports [no test files], no failure. Cleanup options: gitignore the path or use go test ./internal/... in CI. Not a verify failure.Outcome: foundation slice landed across 9 commits (1af5bcb..136ae1f) plus 2 review-fix commits (4ef7a02, 0cf348a); end-to-end browser smoke passed.
internal/shared/wire/ untouched — git log 85a2dd3..HEAD -- internal/shared/wire/ empty.internal/server/auth/ untouched — git log 85a2dd3..HEAD -- internal/server/auth/ empty.GET /api/v1/sessions is a strict superset (existing 9 fields + 5 new aggregates) — verified via curl and repository_test.go.fetch( in web/src, in api/client.ts.web/dist/ has zero committed files; internal/server/web/dist/ has only .gitkeep + placeholder index.html.tweaks-panel.jsx not ported; runtime accent toggle not surfaced.application/problem+json (including 401/403/404/405/415).g-leader and j/k did not guard against palette-open or editable target — typing gh into the palette input fired go('home') mid-query. Fixed in 4ef7a02 with an early-return after Esc handling, plus two regression tests.web-builder worked only by relative-path coincidence (vite output landing at the container root because WORKDIR /web shifted the relative outDir up one level). Fixed in 0cf348a by mirroring the host repo layout (WORKDIR /src, COPY web/ web/). While validating the build, also discovered golang:1.25-alpine no longer compiles the codebase (the auxilia/culpa dep needs errors.AsType, which is in 1.26+); bumped builder image to golang:1.26-alpine and go.mod directive to 1.26.0 in the same commit. docker build now produces a runnable binary end-to-end.SessionsTable Link passes params.id = session.id (full composite). Session view loads correctly because useSession adapter splits it back, but the URL is /session/$tool/$host/$tool%2F$host%2F$id. One-line fix in SessionsTable (pass bare session_id). Justification: cosmetic, not functional; deferred so this commit set stays scoped to fixing reviewer findings.GET /api/v1/sessions/{tool}/{host}/{id} returns the new summary/turn_count/tokens_*_total fields as zero values because the Get path uses sessionSelectColumns (Plan 1.2 said Get unchanged). The SPA reads turns[] directly so it's invisible in this UI, but a future API consumer would see misleading zeros. Justification: explicitly scoped out by Plan 1.2 (Get path unchanged); fixing requires either extending the Get SQL or omitempty on the four numeric tags; either way, scope creep here.Turn TS interface in Plan 6.1 didn't include timestamp, so the meta shows # seq · model · tokens-in→tokens-out only. Justification: explicitly scoped to the spec'd interface; adding it is an additive change in a follow-up.go test ./... walks web/node_modules/flatted/golang/pkg/flatted: stray Go package shipped inside an npm dep; reports [no test files], no failure. Justification: cosmetic; can be addressed by switching CI to go test ./internal/... or gitignoring the path..github/workflows/* or .sourcecraft/ci.yml; neither directory exists in the repo. The CI job (npm ci && npm run build && npm test && npm run lint) is not implemented. To resume: confirm sourcecraft.dev's CI file format and create .sourcecraft/ci.yml, or add .github/workflows/web.yml if GitHub mirroring is in scope.Phase 2 — vite outDir: set to ../internal/server/web/dist/ so vite output lands directly in the directory the Go embed will read in Phase 3. Plan implied a web/dist/ location with an unspecified copy step; collapsing to a single dist location removes that step entirely. Root .gitignore updated accordingly (internal/server/web/dist/* with .gitkeep exception).
Phase 2 — eslint v8 (vs v9): ESLint v9 dropped .eslintrc.cjs support in favor of flat config; downgrade to ^8.57.1 keeps the plan's config format. Acceptable until a future cleanup migrates to flat config.
Phase 2 — separate web/vitest.config.ts: the TanStack Router vite plugin fails at config-resolve when src/routes/ is missing or empty; vitest uses its own config that omits the Router plugin so npm test runs in this phase before routes exist. Phase 4 will populate routes; the separate file remains useful for test-only config divergence.
Phase 2 — web/src/routes/__root.tsx placeholder: required to satisfy the TanStack Router plugin scan at build time; minimal stub that Phase 4 replaces with the real shell-mounted root.
Phase 2 — web/src/test-setup.ts: implied by the testing infrastructure; sets up @testing-library/jest-dom matchers.
Phase 3 — r.Get("/*", …) vs r.Handle("/*", …): plan said Handle (any-method); implementation uses Get (and HEAD). Reason: Handle made POST /healthz return 200 (SPA HTML) instead of 405 problem+json, regressing the existing TestRouter_MethodNotAllowedReturnsProblemJSON invariant. SPA only needs GET (browser navigation); restricting the catch-all is more correct and preserves the 405 behavior for non-GET on unknown paths.
Phase 3 — TestRouter_NotFoundReturnsProblemJSON retargeted: with /* mounted, chi returns 405 (not 404) for non-GET on unknown paths because /* matches the path. The existing notFoundHandler is still wired (in case chi reaches it) but the routing path that previously hit it no longer does. The test now invokes notFoundHandler directly to assert its output.
Phase 5 — keyboard cursor wiring (retroactive Phase 4 amendment): Phase 4 left a static no-op cursor: { move, activate } in __root.tsx's keyboard controller. Phase 5 added cursorRef + KeyboardCursorContext so route-local components can register their cursor and the controller delegates through the ref. This is the pattern the dispatcher's Phase 5 brief instructed; recording so it isn't conflated with Phase 4's omission.
Phase 5 — useHomeCursor.jumpTo(i): plan specified move/activate only; jumpTo added so SessionsTable.onCursor can set the cursor on mouse hover/click. Pure additive surface; no plan invariant violated.
Phase 5 — FilterChips "active filter" set is component-local: plan said filters are URL-driven. The actual filter values (since, tool, host) ARE URL-driven; what's local is "which chips are shown" (e.g. + filter adds host to the displayed chip list). No URL representation was specified for that and adding one is gratuitous.
Phase 5 — ToolDot tool prop widened from literal union to string: real ingest data may include tools outside the prototype's five. CSS class still falls through cleanly.
Phase 5 — session.$tool.$host.$id.tsx placeholder created: needed so TanStack Router types accept Link navigation from Home. Phase 6 replaces the placeholder with the real Session view.
Phase 6 — SessionWithTurns extends Omit<Session, 'turns'>: Session.turns is the aggregate count (number) from Phase 5; SessionWithTurns.turns is Turn[]. Omit resolves the conflict cleanly. SubBar turn-count display reads session.turns.length.
