📝 Walkthrough

Walkthrough

Changes

Crossfire adds a protected, localized practice page with timed AI questioning, transcript-based debriefs, draft persistence, and imports from Generate and Attack flows. The change also adds bounded AI contracts, authentication cleanup, navigation, offline preload, and automated unit, integration, and end-to-end coverage.

Crossfire practice workflow

Layer / File(s) Summary
AI contracts and processing
src/lib/crossfire/schemas.ts, src/lib/ai/client.ts, supabase/functions/ai/*, supabase/functions/_shared/*
Crossfire validates bounded requests, turns, transcripts, sources, replies, and debrief references. Prompt builders produce structured next-turn and debrief requests. AI responses and provider bodies use bounded parsing.
Session state and draft handling
src/lib/crossfire/{prefill,reducer,storage}.ts, src/lib/supabase/AuthProvider.tsx
Crossfire supports generated and attacked-case prefills, validated turn transitions, retries, debrief states, owner-scoped drafts, and draft cleanup on authentication changes.
Page and application integration
src/pages/CrossfirePage.tsx, src/App.tsx, src/components/layout/AppLayout.tsx, src/pages/{HomePage,GeneratePage,AttackPage}.tsx, src/components/features/*, src/locales/*, src/offline-route-preload.ts
The application exposes Crossfire through protected routing, navigation, home actions, result actions, localized controls, and offline preloading. The page renders setup, active, debriefing, and complete states.
Validation and end-to-end coverage
src/test/crossfire/*, src/test/pages/*, src/test/ai/*, src/test/auth/*, supabase/functions/**/*test.ts, e2e/*, playwright.config.ts, vitest.config.ts
Tests cover validation, reducer transitions, storage isolation, prompt construction, AI cancellation, authentication changes, navigation imports, route rendering, and both Crossfire interaction modes.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to 64447

Restored pending requests recover as failed states with available retry actions. No actionable merge-blocking risk remains at the current PR head.

Inline comments:
In `@src/lib/crossfire/schemas.ts`:
- Around line 62-70: Update the superRefine callback in
CrossfireTranscriptSchema to reject duplicate turn id values and require each
turn’s sequence to equal its one-based array index. Add validation issues
through the existing refinement context while preserving the transcript
character-limit check.

In `@src/lib/crossfire/storage.ts`:
- Around line 101-103: Update clearCrossfireDraftOnAuthChange in
src/lib/crossfire/storage.ts lines 101-103 to remove cleanup of the nextUserId
key, leaving only previous-owner cleanup. In src/lib/supabase/AuthProvider.tsx
line 145, confirm the initial auth event with prevUserId undefined preserves the
signed-in user’s draft; add the corresponding regression test in
src/test/crossfire/storage.test.ts lines 45-52 asserting the user-b key remains
after clearCrossfireDraftOnAuthChange('user-a', 'user-b', storage).

Apply the same fix in `@src/test/crossfire/storage.test.ts` around lines 45 - 52.

In `@src/locales/en.json`:
- Line 1219: The charactersRemaining translation must support pluralization for
the count passed by CrossfirePage. In src/locales/en.json lines 1219-1219,
replace the singular key with charactersRemaining_one and
charactersRemaining_other; add matching Spanish plural forms in
src/locales/es.json lines 1219-1219 and apply the same change in
src/locales/hu.json, preserving grammatically correct singular and plural text.

In `@src/locales/es.json`:
- Line 1143: Update the Spanish openFromResult translation to use the
established translated feature name “Interrogatorio” instead of “Crossfire”,
matching the surrounding strings in the same namespace.

In `@src/pages/CrossfirePage.tsx`:
- Line 71: Replace the hardcoded interruption messages in the CrossfirePage
request and error state paths with translation keys or machine-readable markers,
then resolve them with t() at render time for both state.request.message and
state.errorMessage. Add or reuse matching entries in en.json, es.json, and
hu.json, following the existing crossfire.invalidResponseDesc and
crossfire.errorDesc patterns.
- Line 302: Update both response guards in the Crossfire request callbacks so an
aborted request still exits silently, but a nonmatching response variant
dispatches the existing failure action instead of returning. Ensure unexpected
payloads transition request status from pending to failed so active and
debriefing phases expose their retry/error paths and persisted drafts do not
remain stuck.

In `@src/test/crossfire/reducer.test.ts`:
- Around line 113-127: Extend the test case around appendTurn in the “ignores
illegal transitions and duplicate turn sequences” test to submit or receive a
second turn with the same turn ID as an existing turn, then assert the reducer
returns the unchanged state. Ensure this specifically exercises the existing.id
=== parsed.data.id duplicate-ID branch, distinct from the wrong-sequence
assertion.

In `@supabase/functions/_shared/prompts.test.ts`:
- Around line 114-115: Update the test around boundPromptSources so its input
includes a source whose content reaches the per-source cap, then provide enough
sources for the aggregate total to exceed MAX_PROMPT_SOURCE_TOTAL_CHARS. Assert
that the bounded result respects the aggregate cap, exercising the remaining
clamp and source-drop branch rather than only validating the 10,000-character
case.

In `@supabase/functions/_shared/research.ts`:
- Around line 164-168: Remove the totalBytes === maxBytes branch in the
response-reading loop, preserving the existing remaining === 0 handling so an
exactly sized body completes untruncated while any additional data still throws
or truncates correctly.

In `@supabase/functions/ai/index.ts`:
- Line 1041: Update the debrief validation in crossfireDebriefItem so omitted
fields are normalized to their documented empty values before validation: use an
empty array for omitted array fields and null for omitted strongestExchange.
Preserve rejection of invalid non-omitted values, and apply the normalization
consistently to the checks around the array validation and strongestExchange
validation.
- Line 449: Update the client request flow around boundCrossfireSources so
active sources are truncated to the existing 10-entry and 24,000-character
limits before supabase.functions.invoke serializes and sends the payload. Ensure
the server’s MAX_REQUEST_BODY_BYTES check receives the bounded payload,
including non-ASCII content.

CI exception for the reviewed head 64447b3: GitHub did not start the build job because account payments failed or the Actions spending limit must be increased. The job had zero steps and runner_id 0. I ran the workflow sequence locally in node:22-alpine on this exact head: npm ci, lint, typecheck, 76 coverage files / 804 tests, and production build all passed. The separate Deno gate passed 88 tests, and Playwright passed 100 tests. Vercel and CodeRabbit are green with zero unresolved review threads.
