Recover signed document images automatically

[BigSimmo]

Summary

• Automatically recover signed document images from transient signed-URL, network, and image-download failures without requiring the reader to click Retry.
• Keep requests genuinely lazy: the existing viewport boundary still gates signed-URL work, and Next.js native lazy loading remains enabled for observed and prefetched images.
• Classify failures before retrying: terminal 401/403/404 responses remain manual, retryable HTTP/network/image failures are capped at two automatic attempts, and 429 responses honor Retry-After without guessing when the header is absent.
• Preserve the existing manual Retry fallback and signed-URL cache/auth isolation.

Verification

• npm run verify:pr-local
  • Not run: the repository's exclusive verification lane remained occupied by another worktree's legitimate Playwright run.
• npm run format — passed; all non-target files remained unchanged.
• npm test -- tests/signed-image.dom.test.tsx — 18/18 passed on the final behavioral diff.
• npm test -- tests/signed-image.test.ts tests/signed-image.dom.test.tsx tests/api-client-error.test.ts tests/auth-signed-url-cache.dom.test.tsx tests/image-lightbox-url-mode.dom.test.tsx tests/use-batch-signed-urls.dom.test.tsx
  • Blocked before execution by repository coordinator capacity; this was an admission refusal, not a test failure.
• git diff --check — passed before commit.
• npm run verify:ui
  • UI verification not run: the exclusive browser lane was occupied; behavior is covered locally by the focused DOM regression suite.
• npm run verify:release
  • Not run: no release or production deployment was requested.
• Pre-push guard: exact-commit formatting passed; lint and typecheck were not run because the repository coordinator was busy. Hosted CI remains the current source of those checks.

Risk and rollout

• Risk: Low-to-moderate client reliability change. Automatic retries are bounded and limited to retryable failures; persistent failures still expose the existing manual action.
• Rollback: Revert commit e301b36f6 to restore manual-only recovery.
• Provider or production effects: None. No provider calls, deployment, migration, or production configuration changes were made.
• RAG impact: none; retrieval, ranking, answer generation, and citation behavior are unchanged.
• Branch note: the branch was created from an older main and was 25 commits behind at publication; current-main inspection found no direct changes to the five implementation/test files in this PR.

Clinical Governance Preflight

• Source-backed claims still require linked source verification before clinical use
• No patient-identifiable document workflow was introduced or expanded without explicit governance approval
• Supabase target remains Clinical KB Database (sjrfecxgysukkwxsowpy)
• Service-role keys and private document access remain server-only
• Demo/synthetic content remains clearly separated from real clinical sources
• Source metadata, review status, and outdated/unknown-source behavior remain conservative
• Deployment classification/TGA SaMD impact was checked; this changes image transport recovery only, not clinical decision-support behavior

Notes

• Manual Retry remains available after bounded automatic recovery is exhausted or for terminal responses.
• The immutable branch-review record documents the two pre-PR findings that were addressed: status-aware retries and preservation of native lazy loading.

Summary by CodeRabbit

• New Features
  • Signed images now automatically recover from temporary network and server failures.
  • Retry timing honors server-provided cooldowns and limits repeated attempts.
  • Cached images retain native lazy loading to reduce unnecessary downloads.
• Bug Fixes
  • Improved handling of image loading failures, including clearer terminal failure behavior and manual recovery.
  • Signed image URLs refresh after image errors when appropriate.
• Tests
  • Expanded coverage for automatic retries, cooldowns, lazy loading, observer cleanup, and recovery scenarios.

Signed image recovery

Layer / File(s)	Summary
Failure classification and retry metadata src/lib/api-client-error.ts, src/components/clinical-dashboard/use-signed-image-url.ts	Retry-after parsing and retryable-status checks are exported. The hook returns structured failure details and derives the legacy failed flag from them.
Automatic retry and recovery src/components/clinical-dashboard/signed-image.tsx, tests/signed-image.dom.test.tsx, docs/branch-review-records/*.record.md	SignedImage retries retryable failures with bounded delays, honors Retry-After, suppresses unsafe 429 retries, and resets retry state after recovery or manual retry.
Lazy-loading and deferred rendering validation tests/signed-image.dom.test.tsx, tests/signed-image.test.ts	Tests verify native lazy loading, deferred signed-URL requests, intersection handling, observer cleanup, and cached-image behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk:🔵 Low · up to 18683

Automatic signed-image recovery can carry retry state from an earlier endpoint, causing a newly requested image to retry unnecessarily or skip automatic recovery; the verification record also needs to accurately report which checks ran. The issues are localized and mergeable with explicit owner follow-up.

[BigSimmo]

@codex resolve actionable Codex review findings for this pull request and current head using the repository instructions. This is the pull request's single automatic repair pass: do not perform a fresh review, create new standalone findings, or request another review. Work only the existing unresolved Codex threads on the current head. The only repository destination is BigSimmo/Database, and the only branch destination is the pull request head branch codex/image-auto-retry at starting commit e301b36; never publish fixes to a detached or synthetic work branch and never create a stacked pull request. Use the authenticated GitHub connector to commit each approved fix to BigSimmo/Database:codex/image-auto-retry, then verify that the pull request head contains the published commit before reporting success. Always fix P0 and P1 findings. For P2 and lower findings, fix only clear, scoped, low-risk issues; otherwise disposition them with a concise reason. For a fixed thread, reply with as the first line and as the second line. For a no-code disposition, use followed by . These result markers authorize the workflow to close that exact thread only after it verifies a fixed commit is the pull request head; a local-only commit is not a fix. If publication or verification fails, do not use either result marker, do not claim success, and leave the thread open with the blocker. If human input or new authorization is required, do the same. Finish only after every actionable thread is fixed or dispositioned and closed, or explicitly left open for a human decision. Do not update the branch from main, address unrelated reviews, broaden scope, or create more than one scoped fix commit. Do not use external APIs, paid services, credentials, dependency changes, or broad refactors unless explicitly authorized. Add targeted tests where behavior changes and run the narrowest relevant validation.

Summary

• Updated signed-image retry handling so a second consumer no longer removes a newer shared in-flight request. Automatic and manual retries now continue to use the existing endpoint-and-identity deduplication map. src/components/clinical-dashboard/use-signed-image-url.tsL139-L152
• Added a two-consumer regression test proving that an initial failure followed by simultaneous automatic retries produces only two fetches total: one failed request and one shared recovery request. tests/signed-image.dom.test.tsxL59-L82
• Created scoped local commit c4e74484df86d270259362d511f02f9b53b6238e on codex/image-auto-retry.

Publication blocker

The commit could not be pushed to BigSimmo/Database:codex/image-auto-retry: the checkout has no authenticated GitHub credentials, and no make_pr/authenticated GitHub connector is available in this environment. Consequently:

• PR Recover signed document images automatically #2194’s remote head remains unverified.
• I did not post resolution markers or claim the review thread was resolved.
• I did not create a stacked pull request.
• The existing review thread must remain open until the local commit can be published and verified.

Testing

• ✅ PATH=/opt/node24/bin:$PATH npm test -- tests/signed-image.dom.test.tsx — 19 tests passed.
• ✅ PATH=/opt/node24/bin:$PATH npm run format
• ✅ git diff --check
• ✅ git commit -m "fix(documents): preserve retry request deduplication"
• ⚠️git push origin HEAD:refs/heads/codex/image-auto-retry — blocked because Git could not obtain GitHub credentials.
• ⚠️gh auth status — reported that no GitHub host is authenticated.
