closes #373
Added fail-closed canonical claim detail projection parsing.
Added explicit loading, ready, stale, not-found, and error states.
Added retry handling for unavailable or stale projections.
Removed fabricated fallback evidence.
Added focused parser and API failure-state tests.
Updated the UI state model documentation.

Summary by CodeRabbit

  • Claim Details
    • Claim detail views now distinguish loading, stale information, unavailable claims, and errors. Unavailable details include a retry option.
  • Evidence
    • Evidence views show loading, error, and stale-data messages when applicable. When no evidence is available, they display “No evidence available” rather than sample content.

Review in Change Stack →

Navigate logical layers of code changes, visualize relationships, and explore their blast radius.

Walkthrough

The change adds runtime validation for claim-detail projection envelopes and uses projection state to render claim details and evidence. It also documents the projection states and the handling of empty evidence.

Changes

Claim Detail Projection

Layer / File(s) Summary
Projection contract and validation
src/app/types/claim-detail.ts, src/app/types/__tests__/claim-detail.test.ts
Adds envelope, error, and view-state types. The parser validates claim fields and projection metadata. Tests cover a valid envelope, a bare claim, and invalid freshness metadata.
Claim and evidence rendering
src/components/features/claim-verification/ClaimDetails.tsx, src/components/features/claim-verification/EvidenceViewer.tsx, docs/UI_STATE_MODEL.md
Claim details use projection state for not-found, stale, and unavailable cases, with retry actions for errors. Evidence uses supplied or projected evidence, shows projection status messages, and no longer inserts sample evidence. The state model documents these behaviors.

Preserve cancellation during response-body parsing.

If the caller aborts after fetch returns but before response.json() finishes, body reading can reject with AbortError. This catch converts that cancellation to PROJECTION_MALFORMED. The hook then records an error from a request it canceled. Re-throw AbortError here, as the earlier fetch catch does.

Bind the parsed claim to the requested claim ID.

If /api/claims/:id returns a well-shaped envelope for another ID, this function accepts it. ClaimDetails can then display the wrong claim for the requested URL. Compare the parsed claim.id with claimId and reject a mismatch before returning.

Validate each evidence entry before accepting the claim.

An API response with evidence: [null] passes isClaim. The parser then returns that response as a ClaimDetailEnvelope whose claim.evidence promises Evidence[]. Reject malformed entries at this boundary so the projection cannot be marked valid without verified evidence.

Show the empty state for supplied empty evidence.

If rawEvidence is [], the hook has no claim ID and reports error without making a request. The empty-state condition then hides “No evidence available,” leaving the expanded viewer blank. When evidence is supplied, decide the empty state from that evidence rather than the unused projection state.

Handle a missing claim separately from empty evidence.

If the projection request returns 404, the hook reports not-found. This condition displays “No evidence available,” although no claim projection was found. Show a not-found state instead of describing the missing claim as a valid claim with no evidence.

Keep projection data associated with its claim ID and request result.

If claimId changes and the new request fails, data still holds the previous claim. ClaimDetails selects that claim even when the hook reports error or not-found. A failed refresh can likewise continue to show old content without a failure notice. Clear or key data when starting a request, and expose it only when it belongs to the current claim and successful result.

Prevent canceled requests from changing the current loading state.

If claimId changes or a retry starts, cleanup aborts the previous request. Its .finally() still runs and can set isLoading to false while the replacement request remains pending. Guard all completion handlers with the current request identity before updating state.

Display the stale state before rendering claim content.

isStale is never used in the rendered view. When the hook returns ready-stale, the component displays the claim status and evidence without a stale warning or a refresh action. Users cannot distinguish this projection from current claim data.

Align both consumers with the projection hook interface.

useClaimDetailProjection requires a configuration object and returns refetch, not retry. Both consumers currently fail strict TypeScript checking. When a claim or evidence prop is supplied, the undefined argument can also cause config destructuring to throw.
