- Align local commits, clone crosslinking, and rebuilds on canonical Fossil derived-table semantics, including merge-parent `mlink` rows and canonical `plink`, `tagxref`, and `leaf` state. - Reduce large-repository clone cost by reusing validated receive bytes during crosslinking and avoiding redundant whole-repository and per-file lookups. On the 67.6k-blob Fossil corpus, the receive-linker change reduced measured clone wall time from 371.21s to 211.69s and peak RSS from 676.9 MiB to 586.1 MiB. - Allow `cmd/libfossil` to select the SQLite backend at build time: modernc remains the default, while `-tags test_ncruces` selects the ncruces backend for native and js/wasm builds. - Improve sync interoperability and resilience with canonical Fossil, including authenticated sync, dropped-round retries, transactional visibility updates, and deferred crosslinking for temporarily unavailable dependencies. - Correct tag propagation so changes do not cross branch boundaries.

None.

- Existing default CLI builds continue to use the modernc SQLite driver. - Build with `-tags test_ncruces` when the ncruces SQLite backend or js/wasm support is required. - No repository migration or rebuild is required.

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
