extract-libs.ts gains extractAllLibs(): enumerate EVERY <Lib>.kicad_symdir / <Lib>.pretty under the source dirs into in-memory self-contained bodies (reuses the curated path's parse + extends resolution). At KiCad 10.0.x symbols already ship the one-symbol-per-file .kicad_symdir layout, so no split needed.
publish-libs.ts (tsx): per lib, build a SyncManifest (sha256 per item) + encodeBundle, write libs/kicad/<libTag>/<lib>/{manifest,bundle} (immutable) + a top manifest.json listing every lib. Keyed by upstream KiCad lib tag, skip-if-exists (HEAD the top manifest; --force overrides) so it is decoupled from the app deploy. Local + r2 drivers via cdn-store.
Validated over web/backend/.cache: 8 libs / 2154 items; Device bundle decodes to 537 bodies, its /manifest matches the bundle, and symbol/R body hash matches its manifest entry (warm-sync diff stays empty). Same wire format cdn-source.test reads, so publish and client are pinned to one format.
