Tip

PR walkthrough: Open the visual walkthrough

The stats page could saturate shared SQLite readers, delaying ordinary reads and causing workspace/sidebar data to disappear after transient failures. This change bounds analytics admission, removes multiplicative analytics joins, preserves same-workspace context, and provides bounded recovery across desktop and phone surfaces.

Important Changes

  • Aggregate turns, messages, repositories, and activity independently with early workspace, range, and page scoping.
  • Limit shared analytics work to two admitted operations and return a classified busy response while preserving genuine persistence failures.
  • Track route and snapshot request ownership so abandoned reads cannot leave global pending state stuck or overwrite newer data.
  • Retain healthy workspace context when refreshes fail, surface snapshot failures, defer hidden-tab retries, and expose bounded recovery controls.
  • Add desktop and phone regression coverage, production-shaped availability tests, concurrent HTTP benchmark coverage, specifications, work orders, and operations guidance.

Validation

  • Go focused analytics, availability, service, health, and tracker tests passed.
  • Go race tests passed for analytics repository, handlers, service, and required stores.
  • go build ./..., backend persistence tests, and go run ./cmd/sqlguard ./internal passed.
  • Frontend Vitest lifecycle and Stats suites passed: 88 workspace lifecycle tests and 33 Stats tests.
  • pnpm run typecheck, pnpm run lint, pnpm run i18n:check, Prettier checks, and pnpm run build passed.
  • Desktop and phone managed Playwright recovery scenarios passed, including sidebar snapshot recovery and Stats section retry.
  • The production-shaped concurrent HTTP benchmark passed with custom cycle p95 of 3.033 seconds for month range and 1.939 seconds for all range.
  • Documentation catalog validation, specification lint, and git diff --check passed.
  • PostgreSQL parity was not run because KANDEV_TEST_POSTGRES_DSN is not configured. The repository-wide make test remains subject to unrelated baseline environment failures.

It also adds state tracking, retry controls, tests, benchmarks, localization, specifications, and operations documentation.

Changes

Interactive read availability

Layer / File(s) Summary
Analytics admission and busy responses
apps/backend/internal/analytics/errors.go, apps/backend/internal/analytics/repository/**, apps/backend/internal/analytics/handlers/stats_handlers.go
Analytics operations use a two-slot gate with a ten-second deadline. Busy operations map to HTTP 503 with analytics_busy and Retry-After: 2.
Analytics query aggregation and validation
apps/backend/internal/analytics/repository/sqlite/stats.go, apps/backend/internal/analytics/repository/sqlite/*test.go, apps/backend/internal/analytics/handlers/*bench_test.go
Task, repository, and daily activity queries use independent aggregate stages. Parity, availability, health, and benchmark coverage was added.
Stats section retry and rendering
apps/web/app/stats/stats-data.tsx, apps/web/app/stats/stats-page-client.tsx, apps/web/app/stats/*.test.tsx, apps/web/e2e/tests/layout/*stats*
Stats sections classify failures, retain available data, retry transient failures, and expose section-specific accessible retry controls. Copy Stats remains unavailable until all current sections are ready.
Workspace-context state and orchestration
apps/web/lib/state/slices/kanban/*, apps/web/lib/state/workspace-context.ts, apps/web/src/spa-routes.tsx, apps/web/src/kanban-route.tsx, apps/web/hooks/**
Workspace reads now track generations, request IDs, pending state, errors, retry delays, and cancellation. Stale responses are ignored, and failed collections do not overwrite retained data.
Workspace navigation recovery UI
apps/web/components/task/**, apps/web/e2e/tests/layout/*sidebar*, apps/web/src/locales/*
Desktop and mobile task navigation show refresh or access-denied errors, retain task rows when possible, suppress false empty states, and provide retry actions.
Requirements and operational documentation
docs/plans/stats-read-recovery/*, docs/specs/**, docs/public/**
Plans, specifications, feature status, and operations guidance describe the analytics capacity, Stats recovery, and workspace read behavior.

Findings

Reviewed head 60a87ee0.

Suggestion (recommended, doesn't block)

1. normalizeAnalyticsOperationError may misclassify non-timeout SQL errors as busyapps/backend/internal/analytics/repository/sqlite/admission.go:52

If a SQL query returns a non-timeout error (e.g. disk I/O failure) but the operation context's 10-second deadline has already expired by the time the error propagates back through the driver, operation.Err() will be context.DeadlineExceeded and a persistence failure gets wrapped as analytics_busy (a 503). Callers then retry a permanently broken database. The fix is to check the underlying error first:

func normalizeAnalyticsOperationError(parent, operation context.Context, err error) error {
    if err == nil || parent.Err() != nil {
        return err
    }
    if operation.Err() == context.DeadlineExceeded && errors.Is(err, context.DeadlineExceeded) {
        return analytics.NewAnalyticsBusyError(err)
    }
    return err
}

This is a rare edge-case in practice — timeout errors from the driver typically carry the deadline context — but the misclassification could mask persistence failures in production logs.


2. console.error in production snapshot fetch pathapps/web/hooks/domains/kanban/use-all-workflow-snapshots.ts:272

The full error object is logged directly to the browser console in production. Depending on the API client, err may carry the raw HTTP response body or URL paths with workspace identifiers. Consider passing only err.message or a sanitized error string, or routing through a structured error reporting channel.

console.error(
    `[useAllWorkflowSnapshots] Failed to fetch snapshot for workflow "${wf.name}" (${wf.id}):`,
    err,   // ← full error object including potential HTTP response details
);

3. TestAnalyticsReadAvailability busy-waits with runtime.Gosched()apps/backend/internal/analytics/handlers/stats_read_availability_test.go:138

for fixture.reader.Stats().InUse < want {
    if time.Now().After(deadline) { t.Fatalf(...) }
    runtime.Gosched()
}

Polling with only Gosched() is a hot spin-loop that can exhaust CPU on a slow or loaded CI runner and make the test flaky. A time.Sleep(time.Millisecond) in the loop body keeps the 5-second deadline useful without burning cycles. Not a correctness issue but worth hardening.


Positive observations

  • Admission gate implementation is correct: sync.Once initialization is thread-safe; the buffered channel is released in every defer path including query errors (TestAnalyticsAdmissionReleasesOnError covers this explicitly).

  • Query restructuring is correct: Each aggregate CTE (tasks, sessions, turns, messages) scans its table independently. Parameter binding counts for all seven query functions were verified manually and are consistent with the rangeStartPredicate two-parameter pattern.

  • rangeStartArg/rangeStartPredicate pattern is correctly documented: The pair of startArg, startArg binds per predicate (one for ? IS NULL, one for >= ?) is unusual but explained in the docstring. No off-by-one in any of the query bindings.

  • Frontend request-ID ownership model is correct: ownsWorkspaceContextRequest ensures only the current request can update state; a stale response whose requestId no longer matches the store's snapshotRequestId is silently dropped. The cleanup function cancels the in-flight Promise.all generation via fetchGenRef before updating snapshot state.

  • Workspace context retention on failure is correct: When workflow or repository fetches fail in useKanbanRouteBootstrap, the code falls back to existing store items (currentState.workflows.items.filter(...)) rather than clearing them — matching the PR's goal of preserving healthy workspace context.

  • Bounded retries are implemented correctly: Both the sidebar recovery (WORKSPACE_CONTEXT_RETRY_DELAYS_MS) and the stats page (RETRY_DELAYS_MS) cap at two attempts and clear pending timers on unmount and tab-hide.

  • Availability test is strong: TestAnalyticsReadAvailability exercises the core claim — two admitted analytics readers do not block a health probe or a plain SELECT COUNT(*) read — with real goroutines rather than mocks.

  • Security: Authorization gating in parseRequest is centralized; every stats route flows through the workspace-ownership check before any data is read.


Summary

Severity Count
Blocker 0

Verdict: Ready to merge — no blockers found. The admission gate, query restructuring, and frontend recovery model are all sound.

Greptile Summary

This PR reduces analytics pressure and adds bounded recovery for statistics and workspace-context reads.

  • Rewrites expensive statistics queries into independently scoped aggregates.
  • Adds a shared two-operation analytics admission gate and retryable busy responses.
  • Adds request ownership, retained workspace context, bounded retries, and desktop/phone recovery controls.
  • Adds backend parity, availability, benchmark, frontend lifecycle, and Playwright coverage.

Confidence Score: 4/5

The functional recovery and analytics changes appear sound, but the explicit accessibility requirement for stable async-control names must be satisfied before merging.

The only accepted issue is the Stats retry button replacing its accessible name during an active request; no blocking correctness, data-isolation, admission, or security failure remains.

Bound retryAfterMilliseconds to the browser timer range.

throwFromResponse rejects non-finite Retry-After values before creating ApiError. However, a very large finite value can pass that check, and retryAfterMilliseconds can overflow when it multiplies the value by 1000. useEnsureWorkspaceWorkflows then passes the result through Math.max(...) to setTimeout, where an oversized delay can trigger an immediate retry.

Use the browser-safe timer maximum. A 60-second cap is not defined by the repository and changes valid Retry-After behavior.

Suggested fix
+const MAX_BROWSER_TIMEOUT_MS = 2_147_483_647;

 export function retryAfterMilliseconds(error: unknown): number | undefined {
   if (!error || typeof error !== "object") return undefined;

Preserve the hydrated fast path after a retry

requestWorkspaceContextRefresh increments workspaceContextRead.retryVersion, and route unmounts do not reset it. Until resetKanbanWorkspaceContext runs during a workspace switch, a later kanban mount sees a nonzero version and always runs listWorkspaces, fetchUserSettings, listWorkflows, and listRepositories, even when the selected state is hydrated.

Track the current version when the hook mounts. Update it when handling a newer retry version.

settleKanbanRead and settleRouteRead have identical behavior and violate apps/web/AGENTS.md, which prohibits identical functions. Export one generic result type and helper from apps/web/lib/state/workspace-context.ts, then use it at both call sites.

Inline comments:
In `@apps/backend/internal/analytics/repository/sqlite/stats.go`:
- Line 557: Update the completion and in-progress predicates in the relevant
stats query to reuse the archived-task rules from GetGlobalStats and
GetCompletedTaskActivity. Retain t.archived_at in task_repository_scope, exclude
archived tasks from completion unless they are in the final workflow step, and
continue counting archived tasks with state IN_PROGRESS as in progress.

In `@apps/web/app/stats/stats-data.tsx`:
- Line 261: Track the latest fetchKey in a ref alongside scopeRef, updating it
when the selection changes. In both success and failure completion branches of
the stats fetch, require the captured fetchKey to match the current ref before
updating state, while preserving the existing scope and abort checks.

In `@apps/web/components/task/mobile/session-task-switcher-sheet-hooks.ts`:
- Around line 274-280: Separate loadTaskSessionsForTask from the try/catch that
handles listWorkflows and fetchWorkflowSnapshot. Commit the successful
"workflows" workspace-read status before loading task sessions, and handle
task-session failures independently so they cannot overwrite workspace-read
state or be routed through retryWorkspaceContext.

In `@apps/web/hooks/domains/kanban/use-all-workflow-snapshots.ts`:
- Around line 458-459: Update the effect cleanup in the hook’s returned function
to resolve pending refreshes for myGen before incrementing fetchGenRef.current,
matching the ordering used by the workspace-change branch. Preserve the
generation guard and ensure cleanup invalidates the generation only after all
resolvers registered under myGen have been flushed.

Other comments:
In
`@apps/backend/internal/analytics/repository/sqlite/stats_aggregate_parity_test.go`:
- Line 64: Update the aggregate query test around GetRepositoryStats and
GetDailyActivity to create and cancel a separate 100 ms timeout context
immediately before each operation, rather than sharing the context initialized
before both queries.

In `@apps/web/app/stats/stats-page-client.tsx`:
- Line 250: Update the gitData assignment in the stats page client to reuse
git.data whenever it is present, including error states from a failed refresh,
and only use the undefined/averages fallback when no retained data exists.

In `@apps/web/lib/state/workspace-context.ts`:
- Around line 37-39: Bound the positive finite retry delay in the
retryAfterMilliseconds calculation to the browser-safe timer maximum after
converting seconds to milliseconds. Update the helper used by throwFromResponse
and useEnsureWorkspaceWorkflows so oversized values do not overflow or cause
setTimeout to retry immediately, while preserving valid Retry-After durations
below the maximum.

In `@apps/web/src/kanban-route.tsx`:
- Line 118: Update the kanban route’s workspace-context initialization guard
around workspaceContextRetryVersion to capture the retry version on hook mount
and update that captured value when a newer retry is handled, so a remount with
hydrated selected state preserves the fast path while genuinely newer retries
still run the workspace-loading requests.

In `@docs/specs/platform/system-design/interactive-read-availability.md`:
- Around line 120-121: Update the locale requirement in the interactive read
availability design to explicitly cover all six Stats catalogs: en, pseudo,
pt-pt, zh-cn, zh-hk, and zh-tw. Clarify that the Traditional Chinese pair is
included in this set, and retain the requirement to generate it with the
repository script.

Nitpick comments:
In `@apps/web/src/kanban-route.tsx`:
- Around line 283-291: Move the generic KanbanReadResult type and
settleKanbanRead helper into apps/web/lib/state/workspace-context.ts, export
them under shared names, and replace both settleKanbanRead and settleRouteRead
call sites with the shared helper while preserving their existing success and
error behavior.

In `@apps/web/src/spa-routes.workspace.test.tsx`:
- Line 422: Update the Repository fixture near the existing cast to use properly
branded RepositoryId and WorkspaceId values, remove the unsupported path field,
and replace the double cast with satisfies Repository so TypeScript validates
the fixture’s shape.
