Read guideWire ZIP → TAR.GZ into code review, CI, and reproducible-build workflows. The real automation surface: the @jadapps/runner on 127.0.0.1:9789, the GET schema API, and the metadata caveats (mode 0644, current-time mtime) that affect determinism.

Read guideFit the ZIP to 7Z tool into day-to-day dev work: triaging a downloaded artifact, normalising a release ZIP to TAR.GZ, byte-lossless re-packs without a terminal.

Read guideAdd build metadata to release ZIPs, or sanitise a leaked comment, without re-archiving — entry bytes stay identical so reproducible-build hashes hold. Plus the CLI equivalents for CI pipelines.
Read guideFold the Timestamp Normaliser into reproducible-build, CI artifact, and cache-key workflows. Canonicalise every archive entry's mtime to a fixed date so build outputs hash identically across machines. In-browser via fflate/libarchive WASM; Pro+ can offload to the @jadapps/runner.
