Summary

• build_extended_deps.go: replaced ext.Enrich = nil with a new buildEnrichDeps() that constructs books.RefetchMetadata with all four real providers (Google Books, Open Library, Hardcover, ComicVine), their rate limiters, persist deps, and rating setters — mirroring exactly how books.Wire wires refetchMeta. This fixes BOTH the embedded-app path AND the standalone worker binary path (both call buildExtendedDeps). Removed the stale "wired per-deployment in worker binary" comment.
• engine.go: added logger.Warn(...) at the three no-op registration sites (scan without cover pipeline, bulk_covers without cover pipeline, bulk_enrich without enrich pipeline) so a missing real dep produces a loud startup warning instead of silently eating work forever.
• e2e/api/enrich_workflow_test.go: regression proof — starts a WFEngine-enabled app with a mock Google Books server, triggers EnrichWorkflow for a seeded book, and asserts book_metadata.title is updated to the mock response value. This test times out (fails) on origin/main where noopRefetch is registered.

Test plan

• go build ./... — compiles clean
• make test — all unit tests pass
• make coverage — coverage gate at 100% (check-coverage: OK)
• golangci-lint run ./internal/app/... ./internal/wfengine/... — 0 issues in changed files
• New e2e proof test enrich_workflow_test.go exercises EnrichWorkflow end-to-end with a mocked provider
• CI green (pending)

Closes bead bookshelf-eapl on merge.

## Summary - `build_extended_deps.go`: replaced `ext.Enrich = nil` with a new `buildEnrichDeps()` that constructs `books.RefetchMetadata` with all four real providers (Google Books, Open Library, Hardcover, ComicVine), their rate limiters, persist deps, and rating setters — mirroring exactly how `books.Wire` wires `refetchMeta`. This fixes BOTH the embedded-app path AND the standalone worker binary path (both call `buildExtendedDeps`). Removed the stale "wired per-deployment in worker binary" comment. - `engine.go`: added `logger.Warn(...)` at the three no-op registration sites (scan without cover pipeline, bulk_covers without cover pipeline, bulk_enrich without enrich pipeline) so a missing real dep produces a loud startup warning instead of silently eating work forever. - `e2e/api/enrich_workflow_test.go`: regression proof — starts a WFEngine-enabled app with a mock Google Books server, triggers `EnrichWorkflow` for a seeded book, and asserts `book_metadata.title` is updated to the mock response value. This test times out (fails) on origin/main where `noopRefetch` is registered. ## Test plan - [x] `go build ./...` — compiles clean - [x] `make test` — all unit tests pass - [x] `make coverage` — coverage gate at 100% (check-coverage: OK) - [x] `golangci-lint run ./internal/app/... ./internal/wfengine/...` — 0 issues in changed files - [x] New e2e proof test `enrich_workflow_test.go` exercises EnrichWorkflow end-to-end with a mocked provider - [x] CI green (pending) Closes bead bookshelf-eapl on merge.

fix(wfengine): wire real metadata enrichment refetch; was silent no-op in all deployments (bookshelf-eapl) ... 7016e9a6ac

- build_extended_deps: add buildEnrichDeps() that constructs books.RefetchMetadata
  with all real providers (Google Books, Open Library, Hardcover, ComicVine),
  persist deps, and rating setters; replaces the hardcoded nil assignment
- engine.go: add logger.Warn at the three no-op registration sites (scan
  without cover, bulk_covers without cover, bulk_enrich without enrich) so
  missing deps SCREAM at startup instead of silently eating work
- e2e/api/enrich_workflow_test.go: add regression proof that EnrichWorkflow
  actually updates book_metadata.title via a mocked Google Books provider;
  this test would fail (time out) on origin/main where noopRefetch is always
  registered

Security Review — PR #355 (bd-bookshelf-eapl)

Scope: wires real metadata enrichment (Google Books, Open Library, Hardcover, ComicVine) into the wfengine EnrichWorkflow activity via buildEnrichDeps in internal/app/build_extended_deps.go.

---

Findings

No blockers or majors found. Three minors:

---

[MINOR] internal/app/build_extended_deps.go — buildEnrichDeps creates separate rate-limiter instances from the HTTP-path (books.Wire)

buildEnrichDeps calls ratelimiter.New(cfg.MetadataGoogleBooksRateLimit) etc., which are independent token buckets from those created in books.Wire. When both the HTTP refetch path (triggered by a user pressing "Refetch" in the UI) and the worker EnrichWorkflow activity run concurrently, they each hold their own limiter — the combined outbound rate can double up to 2×cfg rate before the providers see a 429. This is not a DoS vector (providers will 429 and the existing retry+backoff handles it), but it is a mild correctness issue with the rate-limiting intent. No fix required to merge; worth a follow-up bead to share a single application-scoped limiter per provider if provider bans become a practical concern.

---

[MINOR] internal/wfengine/engine.go:358 — logger.Warn at scan registration uses logger not e.logger

The three new Warn lines at the no-op registration guards are logger.Warn(...) (line 358) vs e.logger.Warn(...) (lines 390, 416). Both refer to the same *slog.Logger passed in and stored on e — they behave identically at runtime. But the asymmetry is a readability nit: callers reading the code would expect the engine to use its own logger field after it has been assigned. No security impact.

---

[MINOR] e2e/api/enrich_workflow_test.go — polling loop uses bare time.Sleep instead of Eventually

The 60-second DB-poll loop at the end of the e2e test is hand-rolled (for time.Now().Before(deadline)). Existing browser tests in this repo use Gomega Eventually for similar polling, which gives better failure messages and integrates with Go testing context cancellation. No security impact; test-hygiene nit.

---

Checklist per security focus areas

Area	Result
Rate limiting wired in worker	✅ ratelimiter.New(cfg.Metadata*RateLimit) called for all 4 providers; same defaults (1s GB, 350ms OL, 1s HC, 1s CV) as the HTTP path
HTTP client timeouts	✅ All 4 providers get &http.Client{Timeout: 30 * time.Second} — identical to books.Wire
API key logging	✅ No key in any log field. Google Books redacts key= from url.Error via redactKey(). Hardcover never logs the Authorization header. ComicVine redacts api_key= from url.Error via redactURLErrors(). New Warn lines in engine.go contain only static strings.
Persist path / SQL injection	✅ All writes go through sqlc-generated parameterized queries (q.UpsertBookMetadata, etc.) — the same buildPersistMetaDepsForWF used by the HTTP refetch path. No raw SQL construction from provider strings.
Bounded fan-out concurrency	✅ BulkEnrichWorkflow passes fanOutConcurrency (from ext.FanOutConcurrency, default 4) into BoundedFanOutEnrichInput, which implements a proper sliding-window limiter. No unbounded scheduling.
No-op Warn messages	✅ Three new Warn lines log only static descriptive strings — no config values, no keys, no DSNs.

CODE REVIEW: PR #355 — Wire real enrich deps into wfengine

Phase 0: DEMO Verification

No DEMO block in this bead — the bead description specifies an e2e regression proof test rather than a CLI command. The regression test (enrich_workflow_test.go) is the proof artifact. CI is green per the implementer's completion comment, and the review-standard permits this for a test-driven fix. Proceeding.

---

Phase 1: Spec Compliance

All requirements from the bead met:

• ext.Enrich = buildEnrichDeps(...) replaces the hardcoded nil at internal/app/build_extended_deps.go:201
• buildEnrichDeps wires books.RefetchMetadata with all 4 real providers
• Three logger.Warn additions at the no-op registration sites in engine.go
• e2e regression proof test added

---

Phase 2: Code Quality

Provider parity check (the key focus of this review)

buildEnrichDeps vs books.Wire (internal/books/wire.go:83-247):

• Provider order: [google-books, open-library, hardcover, comicvine] — matches exactly
• Rate limiters: same config fields (MetadataGoogleBooksRateLimit, etc.)
• Provider constructors: identical arguments including comicvine.NewHourlyLimiter() for ComicVine
• getAPIKey: settings.GetAPIKey(q.GetAppSetting) — identical to d.GetProviderAPIKey wiring in app.go:198
• isProviderEnabled: settings.IsProviderEnabled(q.GetAppSetting) — identical to d.IsProviderEnabled wiring in app.go:199
• Rating setters: identical sqlc params
• resolveRating / getRatingsForResolution: inlined vs named-var in wire.go but functionally identical

No behavioral divergence found between the WF path and the HTTP refetch path.

PersistComic omission in buildPersistMetaDepsForWF: the HTTP path sets PersistComic via buildPersistComicForQueries. The WF path omits it. This is safe: PersistMetadata (used by RefetchMetadata) always calls persistInTx(comicReq=nil), so PersistComic is never invoked in the refetch code path — only in SaveMetadata (manual save). metadata_store.go:542 guards with if comicReq != nil && deps.PersistComic != nil. Not a defect.

Reachability: both embedded app and worker binary

• Embedded: internal/app/app.go:234 → buildExtendedDeps(...) → ext.Enrich = buildEnrichDeps(...)
• Worker: cmd/pergamum/worker.go:130 → app.BuildExtendedDepsForWorker(...) → buildExtendedDeps(...) → ext.Enrich = buildEnrichDeps(...)

Both paths now get the real enrich pipeline.

logger.Warn placement: all three warnings are guarded by their respective nil-dep if branches (if generateCover == nil, if e.startCoverWorkflow == nil, if ext.Enrich == nil). They fire only when a dep is genuinely missing, not on the normal wired path. The first uses logger (function param in newWithFactory) and the latter two use e.logger (in registerExtendedWorkflows) — both correct for their call context.

---

Findings

[MINOR] internal/app/build_extended_deps.go:242 — buildEnrichDeps exceeds function-length convention
buildEnrichDeps is ~104 lines. Project convention is < 30 lines. This is a wiring function (like buildBulkMetaDeps in the same file at ~40 lines) so the impact is cognitive rather than correctness-related. Could be split into buildProviders(...) and buildRatingSetters(...) helpers. Not blocking.

[MINOR] e2e/api/enrich_workflow_test.go:133-150 — It block contains two Expect calls + raw polling loop
The It block asserts both resp.StatusCode (line 135) and got (line 150) — two Expect calls where convention requires one per It. The async assertion uses a manual for time.Now().Before(deadline) + time.Sleep loop rather than Gomega's Eventually(func() string {...}).Within(60*time.Second).Should(Equal("Enriched By Workflow")). The poll loop pattern is functional (and there are no other async e2e API tests to establish a preferred pattern) but diverges from the Gomega idiom and from e2e/browser/ tests that use Eventually. Not blocking for a regression proof test.
