f81cf1cRelease session resources on partial-setup and error paths Two leaks in the syncer session lifecycle: - newSession opened the source transport (and started the memory-measurement ticker goroutine) before listing refs and setting up the target. If any of those steps failed it returned nil, err, so the caller had no session to finish() — leaking the source conn (an SSH transport spawns a process), a half-open target conn, and the ticker goroutine. - finish() never stopped the measurement ticker; it was only stopped when a Result was built, so any early error return from runSync et al. leaked the goroutine even on a fully-constructed session. Add a success-guarded deferred cleanup in newSession that calls finish() unless the session is handed back, hand the target conn to the session as soon as it is opened so cleanup can close it, and have finish() also invoke the sync.Once-guarded measurementDone so the ticker stops on every path.

db22241git-sync-bench: exit non-zero on failed runs, drop -1 sentinels Two reporting bugs: - run() returned nil after printing the report regardless of outcome, so the process exited 0 even when every benchmark run failed — a failure could pass for success in CI. Return an error (after printing the report) when any run failed. - The aggregate Min* fields start at -1 as an "unset" sentinel updated by the first qualifying run. With no successful (or no batched) run the sentinel survived into the report, emitting minWallMillis=-1 etc. Clear the sentinels to 0 when there were no qualifying runs.

6b45fb8go.mod and test hygiene Four small hygiene fixes flagged in review: - go.mod pinned `go 1.26.2` in the go directive, forcing that exact patch toolchain on everyone. Use `go 1.26` for the language requirement plus a `toolchain go1.26.2` line. - ExampleClient_Sync ran with no timeout (the review flagged real network I/O during go test). The repo's golangci-lint config enforces testableexamples, so the example must keep its `// Output:` directive and remain runnable; instead of dropping it, bound the call with a 30s context deadline so it can't hang. The example hosts are RFC 2606 reserved names that don't resolve, so it fails fast and prints nothing. - The smart-HTTP test server's handlers called s.tb.Fatalf from the server's goroutines, where Fatalf's runtime.Goexit doesn't stop the test correctly. Use s.tb.Errorf (safe from any goroutine); each call is the handler's final statement, so the handler still returns. - SyncRequest.Validate and PlanRequest.Validate were byte-for-byte duplicates; extract validateSyncFields and have both delegate.

0eb86b0Use a real Windows lock for the file token store The initial Windows shim made the package compile but its lock was a no-op, so two concurrent file-store writers could lose an update or collide on the shared ".tmp" file. Use LockFileEx/UnlockFileEx (golang.org/x/sys/windows, already a dependency) on the ".lock" file for the same blocking, interprocess advisory exclusion the Unix path gets from flock, which serializes writeFileToken's read-modify-write. Promotes golang.org/x/sys to a direct dependency. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Entire-Checkpoint: aef01c5e047d+39/-14
