Summary

Syncs main with upstream Silo-Server/silo-plugin-metadata-audiobook main via a real merge, so upstream stays in ancestry.

Upstream commits (6):

  • feat(provider): make search sources configurable and stop scraping Audible product pages during search (#11): adds a sources global config schema with a switch per source. The defaults are Audnexus, Apple Books, and AudiobookCovers; the scrapers and AudiMeta are opt-in.
  • fix(provider): backfill missing cover from cover-bearing sources (#3)
  • fix(audnexus): treat a 404 ASIN lookup as no match (#7)
  • fix(provider): stop silently writing off matchable audiobooks (#9): adds gRPC status mapping, and google.golang.org/grpc moves to a direct require.
  • fix(audnexus): use /books/search for title lookups (#8)
  • docs: standardize contribution guidance (#10)

The new upstream code, tests, and docs are rebranded:

  • github.com/Silo-Server/silo-plugin-audiobook-metadata becomes github.com/prairie-server/prairie-plugin-metadata-audiobook.
  • The SDK and proto imports become github.com/prairie-server/prairie-plugin-sdk/.../pluginproto/prairie/plugin/v1.
  • Comments that mention "Silo" or "silo-server" now say Prairie.
  • Doc links point to Prairie-Server.

plugin_id: prairie.audiobook-metadata, prairie_api_version, and the current SDK pseudo-version require are unchanged. No newer SDK API is needed: pkg/pluginsdk/manifest is already in the pinned Prairie SDK.

Behavior change for users: after this lands, the Audible, Storytel, BookBeat, Audioteka, and AudiMeta scrapers are off by default for title searches. ID lookups still resolve through them.

Conflict notes

  • manifest.json: took upstream's new description and setup text (rebranded to Prairie audiobook libraries), and kept Prairie's homepage, source, support, changelog, and publisher fields. Upstream's new sources schema auto-merged.
  • main_test.go: import block conflict only. Kept Prairie's import paths. The new upstream TestRuntimeServerConfigureAppliesSources merged in.
  • README.md: Prairie had a short three-line README, and upstream rewrote it with Sources, Configuration, Development, Contributing, and License sections. I took upstream's version and rebranded it.
  • Leftover not touched: .gitignore still ignores /silo-plugin-audiobook-metadata, same as on main.
  • Follow-up commit (CI fix): four Prairie-only coverage tests (main_test.go and provider/coverage_http_test.go) encoded the pre-merge behavior, so they failed. They now enable every source where they exercise scrapers, use upstream's audible_search_cards.html fixture for the Audible search test (I removed the now-unused audible_search.html), expect an Audnexus 404 to mean no match, and expect *ProvidersFailedError when every source fails. Coverage is 95.2% against the 95% floor.
  • CI caveat: ci.yml runs go test ... || true, so a failing test only shows up through the coverage floor. That is worth tightening separately.

Release / deploy note

Release workflow only runs on v* tags or manual dispatch, so merging does not publish anything. CI runs on PR and on push to main. The manifest version (0.1.3) was not bumped; a release needs a bump and a tag.

Merge with 'Create a merge commit' — do not squash.

* docs: standardize contribution guidance

* docs: address review feedback
The title search built its URL as /books?q=, which is not a route on
api.audnex.us. The API answers it with

  {"message":"Route GET:/books?q=... not found","statusCode":404}

so every title search this client ever issued failed -- silently, since
a 404 surfaces as "no results" rather than an error. That hit exactly
the audiobooks that need identifying: audnexus is first in the provider
fan-out and is the preferred source, but it can only answer by ASIN, and
an item with no ASIN is precisely the one being searched for. The result
is that audnexus contributed nothing to unidentified items while
appearing to participate.

The correct route is /books/search. Verified against 20 unidentified
production audiobooks: the old path returned 404 on all 20, the correct
path answered 18, and scoring those against the library titles accepted
16 -- ahead of iTunes at 12 on the same sample.

Notably the right book is often not the top row: audnexus returned
Ghosthound 13 for a Ghosthound 1 item, "The Bitcoin Standard" for
"Bitcoin", and "The Good Mothers" for "Mother of Storms". All three
resolve correctly once the caller scores the candidate list instead of
taking results[0].

The bug survived because the existing tests' stub server answers any
path, so the wrong URL still returned the fixture. Both new tests assert
the path itself: the title route and the by-ASIN fetch route.

Rebased onto main after #8; Audnexus title search stays enabled via /books/search, the rest of the branch is unchanged: iTunes Fetch via the lookup endpoint, a typed all-providers-failed error surfaced as a gRPC code, and a 25s per-provider deadline.
get() reports an unknown or delisted ASIN as a nil body; decoding that nil
body surfaced as a bogus "unexpected end of JSON input" error instead of
"no match". Guard Fetch the same way Search already does.

Reduced from the original #7 by Rhainland: the iTunes Fetch and the Audnexus
search changes landed through #8 and #9.

Rebased onto main after #8, #9 and #7. Added a unit test for the backfill (graft from AudiobookCovers by ASIN, keep an existing cover without a request, skip when there is no ASIN) and reworded a stray comment.
…dible product pages during search (Silo-Server#11)

* feat(provider): make search sources configurable and stop scraping Audible product pages during search

Every title search fanned out to all eight sources and waited for the
slowest. Audible's search fetched the results page and then three product
pages, each waiting on a six-per-minute token bucket, so a search took about
twenty seconds even though Audnexus and Apple Books had answered in under a
second.

Add a "sources" global config with a switch per source. Audnexus, Apple
Books and AudiobookCovers are on by default; the four scrapers and AudiMeta
are off. A disabled source still resolves an ID it already owns through
Fetch, so items that carry an ASIN or Apple Books ID keep working.

Audible search now reads the result cards directly (ASIN, title, cover,
author, narrator, length) and leaves the product page to Fetch. One request
per search instead of four.

Live timing for three test titles: 0.1s to 3.0s with the defaults, 3.0s to
7.8s with Audible enabled, down from about 20s.

📝 Walkthrough

Walkthrough

The plugin now supports configurable title-search sources, aggregates provider failures, updates Audible, Audnexus, and iTunes lookup behavior, and backfills missing covers. Repository instructions and contribution guidance have also been added or expanded.

Changes

Audiobook metadata provider

Layer / File(s) Summary
Configure search sources
manifest.json, provider/provider.go, main.go, main_test.go, manifest_test.go, provider/provider_sources_test.go, README.md
The manifest and runtime support eight configurable title-search sources. Audnexus, iTunes, and AudiobookCovers are enabled by default. Tests check defaults, configuration parsing, and source selection.
Aggregate search failures and map status codes
provider/provider.go, main.go, go.mod, main_status_test.go, main_test.go, provider/provider_test.go, provider/coverage_http_test.go
Search returns ProvidersFailedError when all enabled sources fail and no matches are found. The runtime maps provider failures to gRPC Unavailable or ResourceExhausted for rate limits.
Parse Audible search cards
provider/audible_scrape.go, provider/audible_scrape_test.go, provider/coverage_http_test.go, provider/testdata/*
Audible search parses up to five results from the results page without requesting product pages. Tests cover card metadata, result limits, and runtime parsing.
Update Audnexus and iTunes lookups
provider/audnexus.go, provider/audnexus_test.go, provider/itunes.go, provider/itunes_test.go, provider/coverage_http_test.go
Audnexus title search uses /books/search and treats a nil response body as no match. iTunes Fetch performs a lookup by collection ID.
Backfill missing covers
provider/provider.go, provider/provider_backfill_test.go
When a fetched match has an ASIN but no cover, the provider tries AudiobookCovers, Audnexus, then AudiMeta.

Repository guidance and documentation

Layer / File(s) Summary
Set contributor and agent guidance
AGENTS.md, CLAUDE.md, CONTRIBUTING.md
The repository adds agent and contribution instructions for repository references, prose editing, development constraints, validation, and pull request requirements.
Update root ignore rules
.gitignore
The ignore rules now target root-level .agents/ and .claude/ directories.

Merge Risk: 🟡 Moderate · up to c10dc

Title searches can keep unmatched items retrying whenever an enabled source is blocked. iTunes ID lookups may attach the wrong book's metadata, and the gRPC dependency has known advisories. Resolve these issues before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to c10dc

The new cover-backfill flow can send a requested audiobook ID to additional external services. An existing gRPC dependency finding also remains unresolved, although this PR does not change its pinned version. The plugin host’s access controls and startup ordering are not available for review.

Retained concerns

  • Low · security · inferred: A coverless ID lookup now fans its ASIN out to additional external cover-bearing services, including services disabled for title search. This broadens disclosure of the requested audiobook ID beyond the primary lookup; the search-only scope of the switches is documented, so this is not an established configuration bypass.
Security review details

Security Blast Radius

  • inferred — The additional cross-service disclosure is limited to ASIN-bearing fetches whose primary match lacks a cover; it does not show a path for caller-selected hosts or credentials.

Security Findings and Attack Paths

  • inferred — A retained denial-of-service finding concerns the pinned gRPC dependency. The version is unchanged by this PR, and the available evidence does not establish that the new status mapping increases exposure to the affected code path.

Trust Boundaries and Controls

  • observed — Search accepts request query fields at the existing metadata handler and delegates to the provider coordinator. Configure can alter shared provider selection, but caller authorization for that runtime method is not established by the plugin source.

Resilience and Maintainability Implications

  • observed — Provider searches use a bounded worker semaphore and per-provider timeout. Aggregate client errors name providers and failure kinds rather than forwarding underlying provider error strings.

Hardening Proposals

  • proposed — If source switches are intended to limit all third-party disclosure rather than title searches alone, make cover-backfill egress a separate explicit setting or apply an outbound-source policy to it.

Upstream made scrapers opt-in for title search, reads Audible search
cards instead of product pages, maps an Audnexus 404 to no match, and
returns ProvidersFailedError when every source fails. Enable all
sources where the tests exercise scrapers, switch the Audible search
test to the card fixture, and update the 404 and all-failed assertions.

Align the SDK requirement with go.mod.

Return only the requested collection.

If /lookup returns a collection with a CollectionID different from id, this loop returns that collection as the requested book. Apple documents lookups that expand an artist ID into related collections, so a nonzero CollectionID alone does not establish identity. Compare each CollectionID with the requested numeric ID before returning a match. Otherwise, Fetch can attach another book’s metadata to the item. (developer.apple.com)

Synchronize the request counter.

The httptest handler increments coverHits in a server goroutine. The subtest resets and reads coverHits without synchronization. This is a data race that can make go test -race fail. Use an atomic counter for all three accesses. (go.dev)

Replace the unsynchronized coverHits counter in the httptest handler and subtest

A failed source turns a true no-match result into an error that is retried forever.

The condition len(all) == 0 && len(failures) > 0 returns ProvidersFailedError when any source fails. It does not require every source to fail. The doc comments at Lines 147-150 and Line 209 say "every source failed". The code does not do that.

Example trigger: an operator enables audimeta, and the hosted API answers 403 to every request (manifest Line 108). A title search then finds no match in Audnexus and iTunes, and AudiMeta fails. Search returns ProvidersFailedError, and searchFailureStatus maps it to codes.Unavailable. The host never records no_match, so it retries the item indefinitely. A long-term FailureBlocked source keeps every unmatched item in the retry loop.

Choose one contract and apply it in both the code and the comments:

  • Return the error only when every enabled source fails (len(failures) == len(tasks)).
  • Or leave out FailureBlocked failures when you decide between an error and a clean no-match.
Proposed fix (every source failed)
-	if len(all) == 0 && len(failures) > 0 {
+	if len(all) == 0 && len(failures) == len(tasks) {
 		return nil, &ProvidersFailedError{Failures: failures}

Update the Search failure condition so it returns ProvidersFailedError only when
no matches were found and every enabled provider task failed; keep partial
failures with successful no-match responses as a clean no-match. Align the
nearby comments with this condition.

Every source still resolves an ID it already knows (an ASIN or Apple Books ID
on the item), whether or not it is enabled for title searches.

Match the README to the code for ID resolution.

The README says that every source resolves a known ID, but fetchPrimary does not do this in all cases. For a bare asin with no provider hint, only Audnexus and then AudiMeta resolve it. Audible and AudiobookCovers do not. Make the sentence narrower, for example: "IDs already on the item still resolve through Fetch, whether or not the source is enabled for title searches."

Narrow the README’s ID-resolution sentence to match fetchPrimary: state that IDs
already on the item resolve through Fetch regardless of whether the source is
enabled for title searches, rather than claiming every source resolves them.
