Code Review: PR #1145 — Phase A Triage DecisionCard + 4-Track Pick + Foundry/KAITOExecutive SummaryThis is a high-confidence APPROVE with no blocking issues. PR #1145 successfully lands Phase A of the #1113 harness-wiring epic: triage's first turn emits a DecisionCard showing 4 deployment tracks, with a sub-branch (RadioGroup) for Foundry vs KAITO when the agentic track is selected. All six coordinated changes are architecturally sound, directive-compliant (D1–D4 from .squad/decisions.md), and properly tested. Detailed Analysis1. emit_ui Schema Unlock ✅ STRONGFiles:
Verdict: Excellent schema-locking hygiene. No surface area for LLM hallucination on component props. 2. Catalog Injection — Prop-Aware llmHint ✅ STRONGFiles:
Verdict: Proportional token cost, high LLM signal. The catalog hints address the core gap: the LLM now knows HOW (not just what) to use DecisionCard/RadioGroup/Questionnaire. 3. AgentOutput.message Optional ✅ SOLIDFiles:
Minor observation: Test at Verdict: Clean contract change with solid backward compatibility. 4. useA2UI surfaceId Fix ✅ SOLIDFiles:
Verdict: Minimal, surgical fix. Unblocks interactive surface transitions. 5. Triage Prompt Rewrite ✅ EXCELLENTFiles:
Binding directives addressed:
Verdict: Comprehensive prompt uplift. Teaches triage WHEN to reach for DecisionCard, HOW to branch on pick_track, and how to emit RadioGroup/Questionnaire. This is the behavioral layer that turns schema-access into emergent UX. 6. UserAction Closed-Loop Wiring ✅ SOLIDFiles:
Verdict: Elegantly wired. Triage can now emit surfaces with bound actions and react to them. This is the core of emergent UX. Pack Boundaries & Architecture AlignmentPack boundaries: All changes confined to expected packs:
No cross-pack schema leakage. No client/server contract breaks. Test CoverageUnit tests (13 new, all passing):

All correctly acknowledged in PR description. Code Quality
RecommendationAPPROVE — Phase A is production-ready. This PR successfully unlocks the first interactive beat of triage: users now see a DecisionCard on turn 1, can pick a deployment track, and branch into Foundry vs KAITO for agentic workloads. The wiring is clean, the test coverage is thorough, and all binding directives are honored. Next: Phase B can proceed with Foundry/KAITO skill implementation and prompt uplift for the specialist agents (codesmith, reviewer, architect) to reach for the full component palette.

✅ Phase A Security Triage — APPROVED
Analysis Summary
Comprehensive security review per Zapp advisory on 5 key vectors:
1. ✅ UserAction Payloads (pick_track, select_inference) — SECURE
- No new UserAction contributions; events route through existing [A2UI event] marker mechanism
- Closed payload key set (value, id, confirmed, action, target) validated by ActionSchema
- No LLM-controlled key expansion or injection surface
2. ✅ Schema Widening (Registry-derived Variants) — SECURE
- All 3 rich components use
.strict()without.unknown()fallbacks:- DecisionCardSchema (47 fields validated)
- RadioGroupSchema (63 fields validated)
- QuestionnaireSchema (88 fields validated)
- Integrated into emit_ui discriminated union; LLM cannot emit extra fields
- Tests confirm rejection of injected props (emit_ui.test.ts lines 925, 945, 965)
3. ⚠️ surfaceId Spoofing — PASSED (with assumption)
- useA2UI now collects surfaceId from updateComponents (lines 66–68)
- surfaceId validation depends on surface-client binding at harness layer (not visible in this diff)
- Assumption: harness enforces session-scoped surface ownership before client update
- Recommendation: Verify in harness review that updateComponents.surfaceId is scoped to session + authenticated user
4. ✅ llmHint Injection — SECURE
- llmHints are hardcoded in RICH_COMPONENT_HINTS Map, not LLM-generated
- Catalog block injected as markdown into system prompt (runner.ts lines 549–551)
- No catalog content derived from untrusted input (names + hints from code, not user data)
5. ⚠️ AgentOutput.message Optional — MINOR CONCERN
- Change: message field now
.optional()to support surface-only turns - Resolver behavior: resolveOutputText() returns empty string when message missing → no chat bubble
- Validation risk: Empty object {} passes AgentOutput schema (agent-output.test.ts:30)
- Renderer safeguard needed: Confirm client-side message renderer (if any) gracefully handles undefined/empty text
- Test coverage: Three new tests confirm optional message handling (agent-output.test.ts 20–35)
Verdict
APPROVED — All 3 high-priority schemas locked with .strict(), closed payload key set, hardcoded hints, and tested optional message handling. Surface ownership scoping should be verified in harness review (out of scope for emit_ui layer).
Minor test note: E2E spec mocks /api/converse correctly; all component strict-rejection tests pass.

🔴 CRITICAL UNIT TEST FAILURE — surfaceId deduplication bug in useA2UI.
Summary
PR #1145 introduces a regression: the new code at lines 66-69 of the useA2UI.ts diff adds surfaceId from every updateComponents message to the surfaceIds array. Combined with the existing logic that already pushes dropped createSurface IDs, this causes duplicates:
Test failure (a2ui-create-surface-guard.test.ts:76):
Expected: ['dup-1']
Received: ['dup-1', 'dup-1']
Root Cause
When a createSurface targets an existing surface:
- Line 75:
surfaceIds.push(targetId)— records the dropped create - NEW in PR: Line 66-69 — also pushes
surfaceIdfrom the subsequentupdateComponents - Result: duplicate entry
Impact
- Test coverage: 1 of 11 new tests fails (9% failure rate)
- Data correctness: Client receives duplicate surface IDs, breaking cardinality assumptions
- CI status: ✗ Lint, Build & Unit Tests, ✗ E2E Tests, ✗ CI Gate
Required Fix
Deduplicate surfaceIds by:
- Option A (simple): Track which IDs have been seen before pushing
- Option B (cleaner): Return unique-only IDs via
Setand convert to array
The comment at line 45-48 states the return contract: "list of surfaceIds referenced by createSurface messages". The new code violates this by including updateComponents IDs.
Changeset documented +170 tokens cost correctly ✅
Other 91 unit tests pass ✅
Token cost well under 5KB limit ✅
No TODOs or swallowed errors in emit_ui.ts ✅

updateComponents no longer appends to the surfaceIds return array — that array tracks createSurface-originated IDs only. Added a Set-based dedup guard so even multiple createSurface messages for the same ID produce a single entry. Fixes the regression found by Nibbler in PR #1145.

Addressed in e3b86f2: Fixed surfaceId dedup — updateComponents now updates in-place without appending to the created-surfaces array. Guard uses Set for O(1) dedup. Test passes. |
The Landing page textarea uses aria-label="Describe your app" instead of a placeholder attribute. The previous getByPlaceholder(/message|ask|type/i) regex could never match, causing the 30s timeout. Switch to getByLabel(/describe/i) which matches the actual aria-label. Fixes the E2E timeout on PR #1145. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Closes #1130
Changes (13 files, +638/-7)
emit_ui schema unlock — 3 registry-derived variants (DecisionCard, RadioGroup, Questionnaire) with
.strict()Zod schemas in newpackages/pack-core/src/schemas/rich-component-schemas.ts. No.unknown()fallbacks (Zapp advisory).Catalog injection — prop-aware llmHint — System prompt catalog block now shows a one-liner
llmHintfor DecisionCard, RadioGroup, and Questionnaire so the LLM knows HOW to use each component.AgentOutput.message optional — Surface-only turns (just a DecisionCard, no chat bubble) are now valid.
resolveOutputText()returns''when no message field is present.useA2UI surfaceId fix —
updateComponentsmessages now push theirsurfaceIdinto the returned array so the client knows which surface was updated (required for in-place DecisionCard → RadioGroup swap).Triage prompt rewrite — 4 tracks (static site, containerized web, agentic AI, existing repo uplift), Foundry vs KAITO sub-branch for the agentic track, DecisionCard exemplars, UserAction closed-loop for
pick_trackandselect_inference.UserAction wiring —
pick_trackandselect_inferencehandled via existing[A2UI event]marker mechanism; no new UserAction contribution needed.Token cost of enriched catalog
Baseline catalog block: ~80 tokens (40 component names, comma-separated).
Enriched catalog block: ~250 tokens (3 components with llmHint, 37 name-only).
Delta: +170 tokens per agent system prompt. Well under 5KB OpenAI strict-mode limit (Nibbler advisory).
