Three tests started a real fossil server and killed it with Process.Kill() without waiting for the exit. Kill signals but does not reap, so the server could still be writing its -wal/-shm files while t.TempDir()'s cleanup walked the directory. A file appearing mid-walk fails RemoveAll with "directory not empty", which is how TestCloneFromRealFossilUncompressedReply failed on CI while passing locally -- it needs a loaded machine to lose the race.

internal/sync/integration_test.go already did this correctly, Kill followed by Wait, with a comment naming the same failure. This applies that established pattern at the three sites that lacked it.

Separately, the unit-test step ran with -timeout=120s, a per-package budget. CI runs the package binaries concurrently, so under contention internal/manifest and internal/sync exceeded it and panicked with "test timed out" despite finishing in 19s and 34s on an unloaded runner. Raised to 300s, matching the DST step, so the margin does not depend on how busy the runner is. check-in: 2256f5d7ce user: [email protected] tags: trunk

go.work.sum is only consulted for workspace-mode builds. CI never uses the workspace -- every step in test.yml runs GOWORK=off -- so the file earns nothing in the repository and re-churns on any local dependency change. Go regenerates it on demand for anyone building with the workspace active, so untracking it costs nothing and removes the churn.

docs/superpowers was added to .gitignore, but four files under it were already tracked; an ignore rule does not untrack what is already in the index, so the directory kept showing up in diffs regardless. Untrack it so the rule actually takes effect.

Both files stay on disk. Also terminates .gitignore with a newline. check-in: fd413ecc56 user: [email protected] tags: trunk

- 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.

Keep validated receive bytes in a bounded session linker so clone does not expand and hash every artifact again during finalization. Preserve bounded retry, cancellation, replay, and residual-repair behavior.
