Horizon §5.2.3 as the zit 0.7.1 erratum words it. A pushed control artifact is a seed when its U card is the origin's own label (go-libfossil) or it carries a horizon-seed T card under any label. Full text is judged as it arrives. A delta is judged on its expanded content at the end of the request, so a delta whose base arrives later in the same request is caught. A delta never made readable is not identified and stays a dangling delta.

The refusal is atomic: the request rolls back, and the reply is the single error card "seed refused: a seed is private to the clone that holds it; it is never pushed". The horizon-seed name match is kept as an extra check, and now refuses loudly the same way instead of silently dropping the file.

Conformance cases for HZ-5.2-4 cover full text, a delta against a held base, a late delta, the shape under a foreign label (full and late), and a foreign label with no binding card, which is stored. An HZ-5.7-2 case covers the stale-seed check on a late delta. An interop case has zit 0.7.0 push such an artifact to a go-libfossil origin and get refused. check-in: 1afe809b01 user: [email protected] tags: main, trunk

libfossil is a pure-Go implementation of the Fossil SCM, reading and writing the same .fossil SQLite repository format as upstream Fossil.

This is the first public release of code that previously lived in a private repository. The module path is github.com/danmestas/libfossil and the binary is named libfossil to avoid $PATH collisions with upstream fossil.

Included: - Repo lifecycle (create, clone), checkout/checkin, timeline, merge, diff, annotate, shun, tag, branch, bisect, stash, undo/redo - Sync-over-HTTP protocol (client and handler) - Two SQLite drivers: modernc (pure Go, default) and ncruces (wasm-capable) - Observer interfaces (SyncObserver, CheckoutObserver) with an optional OpenTelemetry implementation in observer/otel (separate submodule) - Deterministic simulation testing harness with BUGGIFY fault injection - Kong-based embeddable CLI under cli/ and a standalone binary under cmd/libfossil/ check-in: f5744359d3 user: [email protected] tags: trunk
