* fix(sync): fail-closed staging-dir ownership guard — prevent rm -rf of repo (#1802) Adopts community fix #1827 by @diazMelgarejo (cyre). New lib/staging-guard.ts exports checkOwnedStagingDir(), the single fail-closed predicate for 'safe to recurse-delete or resume into', wired at cleanupStagingDir() (the deletion chokepoint), decideResume(), the ingest entry point, and makeStagingDir() (mints the .gstack-staging marker). Fixes #1802. Co-Authored-By: cyre <diazMelgarejo@users.noreply.github.com> Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(sync): don't route the remote-http persistent transcript dir through cleanup (#1802) The ingest finally ran cleanupStagingDir() unconditionally, but in remote-http mode stagingDir is the PERSISTENT transcript dir (~/.gstack/transcripts/) that gstack-brain-sync push must consume. The remote-http branch documents the intent to skip cleanup, but a finally runs on its return. Gate the call on !remoteHttpMode so the ownership guard only ever sees .staging-ingest-* dirs. Pre-gate this dir was deleted outright (broken artifacts handoff); post-#1827 it produced a false 'prevent data loss' warning every sync. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(sync): preserve staging dir on internal import timeout (#1802 C3) The import-timeout branch printed 'checkpoint preserved' but the finally then deleted the staging dir: the SIGTERM forwarder's preserve branch only runs when the PARENT is signalled, and an internal runGbrainImport timeout kills just the child and returns normally. So #1611 resume-after-timeout never actually worked. Mirror the forwarder in the timeout branch: set preserveStaging only when gbrain checkpointed against this dir (finally then skips cleanup); otherwise clean up and tell the user it restages instead of falsely promising a resume. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(sync): resume must not mark failed files as ingested (#1802 C4) On resume, stagedPathToSource was rebuilt as an empty Map, so readNewFailures() could not map gbrain's per-file failures back to source paths. Every failure fell through to state recording — failed files were silently marked ingested and never retried. Reconstruct the map from the prepared pages via a shared stagedRelPath() helper (single source of truth with writeStaged, so the keys can never drift). Exports stagedRelPath + readNewFailures for a behavioral test proving the reconstructed map recovers the failure the empty map dropped. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * harden(sync): close staging-guard TOCTOU + fail hard on marker write (#1802 C5) checkOwnedStagingDir() now returns the realpath-resolved canonicalPath on a pass, and cleanupStagingDir() rmSync's that instead of the raw input — closing the gap where the input is a symlink swapped between the ownership check and the delete. makeStagingDir() tears down the partial dir and rethrows if the marker write fails, so a marker-less dir (which the guard would refuse forever) can never leak.
