[Claude #1] Stage 1 problem-review — IMP-92 AI fallback config validation
Root cause
Three independent gaps stack onto one operational-noise pain point:
src/config.py:20pinsai_fallback_model = "claude-opus-4-6-20250415". Per CLAUDE.md system reminder the current valid Anthropic IDs areclaude-opus-4-7/claude-sonnet-4-6/claude-haiku-4-5-20251001; the4-6-20250415dated form is suspect and will surface as a 400/404 from Anthropic on first AI fallback call. Failure mode today = ambiguousrecord["error"]string after Step 12 has already burned setup work.src/phase_z2_pipeline.py:3631) only snapshots frame_contracts / templates / V4 source. It never probes the Anthropic API, so an invalid model ID or revoked key only surfaces when Step 12 invokesroute_ai_fallback. Failure shows up late, as a generic string inai_repair_status.error_records[].error.src/phase_z2_ai_fallback/step12.py:205catchesExceptionand storesf"{type(exc).__name__}: {exc}"._summarize_ai_repair_status(src/phase_z2_pipeline.py:778-846) buckets every non-validation failure into a singleerroraxis. FrontendformatAiRepairHumanReviewMessage(Front/client/src/services/designAgentApi.ts:270-287) renders the same Korean string for quota / billing / auth / validation / coverage / unsupported — violatingfeedback_auto_pipeline_first(silent automation for non-operational) and the #84 replacement-plan contract (only operational reaches the user).Verification table

Scope-lock decision: PASS for Stage 1. The active Phase Z AI fallback path has the three gaps described in the issue: stale default model literal, no Step 0 model/API preflight, and no operational API error classification before frontend toast surfacing.

CLAUDE.mdmodel-knowledge block listsclaude-opus-4-7as valid. I found no rootCLAUDE.mdin this workspace and the Stage 1 instruction is grep/find, so I cannot validate the exact current Anthropic model ID from repo files. Implementation should treatclaude-opus-4-7as a candidate and prove it with the required model-ID ping or an authoritative source.APIStatusError.status_code; it does not expose a dedicatedBillingErrorin the checked class list. Implementation should classify billing bystatus_code == 402, not by assuming a named SDK exception.src/kei_client.py:597,:715, and:981. They are outside the activesrc/phase_z2_ai_fallbackpath and should not be pulled into this IMP unless Stage 2 explicitly expands scope.ai_fallback_enabledis false, normal path AI call count must remain zero.Scope recommendation for Stage 2

Rationale:
u1: Covers issue scope 1 config replacement. src/config.py currently pins claude-opus-4-6-20250415 and tests/test_phase_z2_ai_fallback_config.py pins the same value; both must move together.
u2: Covers scope 2 operational classification. Installed Anthropic SDK exposes AuthenticationError, PermissionDeniedError, BadRequestError, RateLimitError, NotFoundError, and APIStatusError, so quota/billing/auth/other can be implemented without string-only routing.
u3: Covers scope 4 backend plumbing. _summarize_ai_repair_status currently drops all structured API context from error_records, so ai_repair_status needs api_error_kind aggregation plus per-record retention.
u4: Covers scope 1 precondition ping and PZ-1. Gate the preflight under ai_fallback_enabled so default-OFF runs incur no API call; invalid key/model becomes a Step 0 setup failure before Step 1.
u5: Covers scope 3 and frontend operational alert contract. designAgentApi.ts currently surfaces error, coverage_violated, and unsupported_kind; replacement must return messages only for quota/billing/auth and null for validation/coverage/unsupported/other.
Out-of-scope notes:
No MDX/sample-specific behavior, no .env edits, no retry-policy semantics change, no AI proposal validation/cache changes, no geometry reconstruction changes, and no frontend copy beyond the operational formatter contract.
Rollback strategy:
Revert the five units as independent patches; u1 is isolated to config/test locks, while u2-u5 can be backed out by removing api_error_kind plumbing and restoring the prior formatter behavior.

Result: incorrect. The patch adds the planned classifier and Step 12 record field, and the targeted Step 12 tests pass, but it does not satisfy the issue's explicit HTTP 402 billing contract. A simulated
anthropic.APIStatusErrorwithresponse.status_code == 402currently classifies asother, so a billing failure from a 402 response would stay silent instead of being surfaced asapi_error_kind="billing".The implementation currently maps billing only through
anthropic.PermissionDeniedError/ HTTP 403. That may be useful as an additional permission/billing surface, but it does not cover the required 402 billing branch from the issue body.=== EVIDENCE ===

The testtest_preflight_skipped_when_disabledlocks this invariant withspy.assert_not_called().classify_operational_errortyped-subclass dispatch (anthropic.AuthenticationError/anthropic.PermissionDeniedError/anthropic.NotFoundError) so the preflight uses the same SDK type ladder as the in-pipeline classifier. These three raiseStep0PreflightErrorwith a single composite message naming the offendingtype(exc).__name__, the configuredai_fallback_model, and the remedial action (Check ANTHROPIC_API_KEY / ai_fallback_model in .env.). The exception chain (raise ... from exc) preserves the original SDK exception for downstream telemetry. Transient typed surfaces (RateLimitError,InternalServerError) are caught separately and recorded as{"status": "transient", "model": ..., "transient_error": "..."}so a temporary 429 / 5xx at boot does NOT block the pipeline — the in-pipeline u2 + u3 layer handles them at runtime.max_tokens=1with a minimalmessages=[{"role":"user","content":"ping"}]payload — no system prompt, no JSON-schema expectation, so the preflight never depends on the AI fallback prompt machinery (avoids therequest_proposalJSON-parse path that would couple boot to schema versioning).ai_preflight = _run_step0_ai_preflight()is invoked BEFORE_write_step_artifact(... 0, "preconditions" ...), and the result dict is merged into the artifactdatapayload under the new"ai_preflight"key alongside the existing seven keys (v4_source,templates_dir,assets_source_base,frame_contracts_loaded,frame_contracts_template_ids,v4_label_to_phase_z_status,mvp1_allowed_statuses).

Verified unit_executed: u4 only.
Result: incorrect. The patch adds the gated Step 0 preflight, records the skipped/passed/transient states, and the focused u4 tests pass. However, it does not satisfy the issue's explicit billing/setup-error contract for HTTP 402. A simulated
anthropic.APIStatusErrorwithresponse.status_code == 402currently escapes as the raw SDKAPIStatusError, not as the clearStep0PreflightErrorfail-fast surface used for setup problems. That means a billing preflight failure would not get the normalized Step 0 setup error message (Check ANTHROPIC_API_KEY / ai_fallback_model in .env.), even though the issue body calls out 402 billing as a distinct operational/setup condition.The implementation currently treats billing only as
anthropic.PermissionDeniedError/ HTTP 403. That may be useful for permission-denied billing surfaces, but it misses the same generic 402 branch that already failed u2 verification earlier and was fixed there by adding status-code fallback dispatch.=== EVIDENCE ===

Verified unit_executed: u5 only.
Result: correct. The frontend formatter now surfaces user-visible AI repair toasts only for the operational Anthropic API error kinds required by IMP-92: quota, billing, and auth. Non-operational AI repair statuses, including coverage_violated, unsupported_kind, generic other API errors, and legacy payloads without api_error_kinds, return null and stay silent. The frontend AiRepairStatus interface matches the backend u3 summary shape, including the aggregate api_error_kinds field and per-record api_error_kind retention. The existing Home.tsx call site remains compatible because it already calls formatAiRepairHumanReviewMessage(...) and only emits toast.error(...) when the helper returns a non-null string.
