Rare Data Club

Rare Data Club's Claude Code plugins: CSS layout primitives, web-archive recovery, archival-grade audio mixdown, lossless video remuxing, and canonical product-catalog curation.

Axiom-enforced CSS layout primitives, Astro 6 site architecture, archival data patterns, and design system tokens. 13 composable primitives, 32 numbered principles, 6 axioms enforced by CI-grade strict-check and JS-budget gates. Zero-JS-by-default, media-query-free, modular-scale spacing.

Recover product databases from defunct e-commerce sites via Wayback Machine, CommonCrawl, and Shopify CDN archaeology. Self-contained 9-stage pipeline: CDX dump, filter, fetch, Shopify CDN discovery, match, download, normalize, build. Supports Shopify, Swell Commerce, Fourthwall, and custom platforms.

Sum a directory of multitrack audio stems into stereo mixdowns (acapella, instrumental, custom groupings) at the highest quality the source material honestly supports. Six-pass pipeline (identify → optional Pro Tools track-name borrow → analyze → plan → mix → verify) with full provenance: SHA-anchored idempotency, sidecar logs per output, declared pan law, ITU-R BS.1770 true-peak headroom, dither when reducing depth, and refusal-by-default for upsampling, normalization, and writing into the source folder. Optional master-reference pipeline (Cmd 19) produces a three-synced-versions reference-bundle and runs a recombine-null + inverse-stems-null verification battery against the released master. Eighteen commandments, all cited by error messages and plan rationale.

Losslessly remux broadcast and web video (.ts, .mpg/.vob, .mkv, broken .mov) into a QuickTime-ready .mov without re-encoding. Five-rung escalation ladder (pure copy → PCM audio → genpts → elementary-stream timeline rebuild → scoped re-encode) with probe/diagnose/verify scripts, dual-track PCM-access + bit-exact-original audio default, field-coded (PAFF) H.264 glitch repair, and decoded-pixel-identity verification of every output. Every codec/container fact verified empirically against a named ffmpeg version; the source file is never touched.

Verify, enrich, finalize, and promote canonical-3.1 product catalogs against a truth-root archive. Wraps an existing 4-axis verifier and collection pipeline behind one CLI engine: one-command verify (no symlink staging), CDN master-rendition fetch resolver, flag-only liveness sweep, propose-only enrichment queue, scaffolds, gated promotion. Ships a curator subagent and a PreToolUse hook that locks metadata.json (POS truth is read-only). Mechanical steps auto-apply; identity/naming/merge/inclusion stay curator-gated.
