paulandClaude Opus 4.8 8496e55baf refactor: extract testable resolve-core + cover album routing; check.sh checks .cjs (closes task/resolver-orchestration-testable)
Source: task/resolver-orchestration-testable (plan/steward-linker-quality) — new album orchestration in resolver.js had zero node:test coverage.

- Extract the pure album/artist orchestration into service/resolve-core.js
  (resolveAll/resolveOne/pickDirect/cacheKey) taking injected search/classify
  fns; resolver.js becomes a thin server wiring the real Spotify search +
  ollama classify. No behavior change.
- Add service/resolver.test.js: self-titled artist+album tie-break, LLM-album
  -> Google fallback, kind-aware cache separation, plus gate/drop/error paths.
- scripts/check.sh: node --check now also matches *.cjs (extract.test.cjs).
- AGENTS.md Testing: note resolve-core coverage + the extract.test.cjs extractor.

Agent rules for the linker repo (reddit → spotify/bandcamp)

A Firefox extension + a tiny Node resolver that turn artist/band names in reddit comments into Spotify/Bandcamp links. This file is the repo-local doctrine; the work is tracked in the towl work-item store under project reddit-spotify-linker.

Stack & layout

  • service/ — zero-dependency Node resolver (Node 18+, built-in fetch/http). resolver.js = the HTTP server; lib.js = pure, side-effect-free logic (the exact-name match precision lever + link shaping) so it's unit-testable; llm.js = pure ollama prompt/parse helpers (the optional local-LLM gate, HTTP-only — no in-process model runtime); lib.test.js + llm.test.js = node:test. The only music API is Spotify (MusicBrainz removed). The resolver confirms both artists and albums: one type=artist,album Spotify search per candidate, exact case-insensitive name match against either; each result carries kind: "artist" | "album".
  • extension/ — Firefox MV2 content script (content.js + extract.js + manifest.json + styles.css). No build step. extract.js is the pure candidate extractor (Title-Case runs + cue phrases for artists; quoted strings + album cue phrases for albums) — node-testable via extract.test.cjs. Album links render italicised (.rsl-album).
  • scripts/check.sh — the local check gate.

How work lands (IMPORTANT — this is NOT the towl repo)

linker is hosted at git.yapplesauce.com/paul/linker, a plain repo: there is no PR pipeline and no branch protection. You push to main directly (via the user's PAT). Do not use towl-orchestrate / worktree+PR here.

  1. Make a small, reversible change.
  2. Run the gate: bash scripts/check.sh (must print ALL CHECKS PASSED).
  3. Commit citing the towl ref (e.g. (task/odesli-direct-links)), push main.
  4. Stamp the SHA on the towl item: stamp_commit { ref, sha, repo: "linker" }.
  5. Close the towl item.

NEVER touch the towl or stickball repos from work scoped to this project.

Testing (zero-dep)

node --test over service/*.test.js exercises lib.js (norm + the exact-name match

  • link builders), llm.js (the classifier prompt/parse), and resolve-core.js (the album/artist orchestration — kindHint tie-break, kind-aware cache key, allowFallback gating — driven with injected fake search/classify fns, no network). Keep pure logic in lib.js/resolve-core.js (not resolver.js, which has the server side effect) so it stays testable without opening a port. extension/extract.test.cjs covers the pure extractor (artist/cue/album candidates) and must be extended with each detection change. Add/extend a test with every logic change. The extension's in-browser behavior is not headlessly testable in this environment — validate content.js with node --check and a documented manual check on a real reddit thread (about:debugging → load temporary add-on).

Code stewards (towl plans under objective/linker-stewardship)

Standing, language-appropriate stewards (adapted from towl's SCOUT→FILE doctrine; run them like any other steward — e.g. via a /loop). Each files findings into towl and fixes small things directly.

  • quality (plan/steward-linker-quality) — correctness + regressions; owns and maintains scripts/check.sh and the node:test suite.
  • design (plan/steward-linker-design) — detection precision/recall, the injected-link UX, README accuracy, reddit-DOM drift.
  • security (plan/steward-linker-security) — DOM injection (build nodes via createElement/textContent, never innerHTML; http(s) hrefs only), minimal extension permissions, bounded external API calls (no SSRF), secrets never logged/committed (.env is gitignored).

Standing decisions

  • Firefox MV2 stays — Mozilla has no deprecation timeline; do not migrate to MV3 speculatively.
  • Optional local LLM is the recommended better-matching path (human override, feedback 2026-06-18 — supersedes the old "no ML/NER" rule). The resolver may call ollama over HTTP (OLLAMA_URL enables it, OLLAMA_MODEL defaults qwen2.5:3b) to classify which candidates are real artists/albums. It stays zero-NPM-dep: HTTP only, no in-process model runtime. The heuristic + Spotify exact-match is the zero-dep default when no LLM is configured.
  • Detection precision lever (zero-dep default): a candidate links only when Spotify returns an artist or album whose name matches it case-insensitively. A confirmed name links to its Spotify artist/album page if available, else a " bandcamp" Google fallback. Album candidates are over-generated from precise signals only (quoted strings + album cue phrases) because album free-text is noisier than artist names — the Spotify exact-match (and/or LLM kind=album) is the filter.
