Isolate spawned Stop hooks through TMPDIR/TMP/TEMP, open transcript fixtures exclusively with private modes, and derive intentional stale-race fixture identity from its opened descriptor.
Preserve main OpenCode lease and activation gates and native Claude namespace receipts. Detect same-size in-place edits using bigint modification and change times during hashing and before deletion; verify both races and actual public CLI reinstall lifecycles.
Port the evidence floor from PR #3480 onto the canonical generation-bound index; preserve policy-v5 anchors and the source PR attribution. Harden PR #3453 receipt metadata and pointer byte bounds.

Isolate deadline fixtures from inherited dry-run/disabled hook flags. Remove an unapproved emoji from the new routing regression to satisfy Unicode validation.
Each writer performs 30 write rounds to widen the race window. Drop the vacuous exitCode liveness assert and the swallowing mid-flight read; instead every wait-loop poll reads and validates the state, so torn reads fail loudly.
Assert dry-run install writes nothing under projectRoot too (cursor target writes there, not home). Rewrite the concurrent writeInstallState test with genuinely overlapping writers via async spawn plus done-file rendezvous, including a mid-flight read; sanitize rendezvous filenames for Windows.
Honor ECC_DRY_RUN=1 in install and repair arg parsing (previously only --dry-run flag worked, so ecc --dry-run install/repair silently performed real writes). Make writeInstallState atomic via writeFileAtomic (O_EXCL staging, fsync, cleanup on failure, atomic rename preserving previous state). Add writeInstallState failure/concurrency/symlink regression tests and disposable-home CLI dry-run regression tests for both global and subcommand forms.
Resolve six conflicts:
- hooks/hooks.metadata.json: keep this branch's gateguard description and
fingerprint, add upstream's hookify-runtime entries.
- package.json: keep both gateguard-report.js and github-coordination.js.
- scripts/hooks/gateguard-fact-force.js, tests/hooks/gateguard-fact-force.test.js,
skills/gateguard/SKILL.md: upstream added a simpler session denial cap; this
branch already has the fuller one (cap threaded through
markCheckedAndCountDenial, malformed-value warning, miss and target notes),
so keep it. Upstream's taskset and su wrapper handling, fail-closed
recursion limit and soft-hyphen sanitising merged cleanly and their tests pass.
- manifests/context-packs/skill-triggers@1.json: take upstream's file and
recompute registryDigest for the merged registry.
Treat non-2xx activity responses as feed errors, preserve non-Markdown Copilot agent assets, and apply the reviewed reference escape parity correction with regenerated bindings. Allow the test runner to drain piped output on its existing success or failure exit status. Validate installed workflows and bounded real Node20/24 pipe regressions.
- A build interrupted while writing the index leaves a partial file under
its digest name before the pointer exists. The next build rejects those
bytes ("content changed under its digest") and cannot repair the index.
- A skill edited after the entries are read leaves an index that still
matches the stored generation, and the next build reports that
generation stale. This pins the current behavior: the index is bound to
the generation, not to live sources.
