Traceability matrix for Part 2 of Component Preparation. Requirements are defined in requirements.md.

Traceability Matrix

Group A — API Route Infrastructure

Requirement	Test / Verification Method	Status
REQ-UE-A01	api-route-utils.test.ts: UUID v4 format validation; uniqueness across calls	pending
REQ-UE-A02	api-route-utils.test.ts: JSON content-type → parsed JSON; other → { raw } ; empty body	pending
REQ-UE-A03	api-route-utils.test.ts: 2xx → 200; 4xx/5xx preserved; body contains ok, status, data	pending
REQ-UE-A04	grep -rn 'generateGuid' src/app/api/ returns no matches; existing route tests pass	pending
REQ-UE-A05	npx jest api-route-utils.test.ts exits 0	pending

Group B — Lookup Response Parsing

Requirement	Test / Verification Method	Status
REQ-UE-B01	Test block for lookupField: plain array, named field, results fallback, empty data	pending
REQ-UE-B02	Existing ardaClient.*.test.ts suites pass unchanged; grep -c 'lookupField' src/lib/ardaClient.ts confirms delegation	pending
REQ-UE-B03	npx jest ardaClient exits 0 with new test cases passing	pending

Group C — JWT / Token Consolidation

Requirement	Test / Verification Method	Status
REQ-UE-C01	grep -rn "atob(.*split.*\[1\])" src/ returns matches only in jwt.ts	pending
REQ-UE-C02	grep -rn "split('\.').length !== 3" src/ returns matches only in jwt.ts	pending
REQ-UE-C03	npx jest jwt.test exits 0; npx jest authThunks exits 0; npx jest tokenRefresh exits 0	pending

Group D — Safe Serialization

Requirement	Test / Verification Method	Status
REQ-UE-D01	storage.test.ts: valid JSON → parsed; malformed → fallback; empty → fallback	pending
REQ-UE-D02	storage.test.ts: key exists → parsed; missing key → fallback; malformed value → fallback	pending
REQ-UE-D03	storage.test.ts: stores serialized value; quota error → no throw	pending
REQ-UE-D04	npx jest storage.test.ts exits 0	pending

Group E — Error Handling

Requirement	Test / Verification Method	Status
REQ-UE-E01	errors.test.ts: Error → .message; string → identity; number/object/null/undefined → String()	pending
REQ-UE-E02	npx jest errors.test.ts exits 0	pending

Group F — Formatters

Requirement	Test / Verification Method	Status
REQ-UE-F01	formatters.test.ts: ISO string → locale date; undefined → '-'	pending
REQ-UE-F02	formatters.test.ts: ISO string → locale date+time; undefined → '-'	pending
REQ-UE-F03	formatters.test.ts: Money → $X.XX CUR; undefined → '-'; null value → '-'	pending
REQ-UE-F04	formatters.test.ts: Quantity → amount unit; undefined → default	pending
REQ-UE-F05	npx jest formatters.test.ts exits 0	pending

Group G — Environment Constants

Requirement	Test / Verification Method	Status
REQ-UE-G01	env-spa.test.ts: constants reflect env var values under different configurations	pending
REQ-UE-G02	grep 'NEXT_PUBLIC_DEPLOY_ENV' src/lib/utils.ts returns no matches; grep 'IS_STAGE' src/lib/utils.ts returns matches	pending
REQ-UE-G03	npx jest env-spa.test.ts exits 0	pending

Cross-Cutting

Requirement	Test / Verification Method	Status
REQ-UE-X01	npx tsc --noEmit exits 0 without changing consumer files beyond import paths	pending
REQ-UE-X02	git diff --name-only shows no changes to existing *.test.ts(x) files (except Group B additions)	pending
REQ-UE-X03	lint, typecheck, tests, build all exit 0 after each group	pending
REQ-UE-X04	grep -A2 'Added|Changed' CHANGELOG.md shows utility extraction entries	pending
