 # Changelog
 
+## [1.26.1.0] - 2026-05-03
+
+## **`gstack-gbrain-sync` ships host-agnostic. Curated artifacts push from Claude Code, Codex CLI, or a dev workspace — same orchestrator, same install, same result.**
+
+The orchestrator resolves its sibling `gstack-brain-sync` binary via `import.meta.dir`, matching the pattern already in `runMemoryIngest`. Path resolution stays anchored to where the script actually lives, not to a hardcoded host install root, so the curated-git-push stage runs end-to-end on every host gstack supports.
+
+### What you can now do
+
+- **Run `gstack-gbrain-sync` from any host install and watch curated artifacts land in the remote.** End-to-end smoke from a Conductor workspace: `bun run bin/gstack-gbrain-sync.ts --incremental --no-code --no-memory --quiet` returns `{"name": "brain-sync", "ran": true, "ok": true, "summary": "curated artifacts pushed"}`. The stage runs on Codex CLI installs and dev checkouts the same way it runs under Claude Code.
+
+### Changed
+
+- `runBrainSyncPush` (`bin/gstack-gbrain-sync.ts:222`) resolves the curated-push binary as a sibling of the running script. One line, single source of truth: `join(import.meta.dir, "gstack-brain-sync")`.
+
+### For contributors
+
+- New regression test in `test/gstack-gbrain-sync.test.ts` pins sibling-resolution behavior so future refactors can't drift the orchestrator back to a host-coupled path.
+- `plan-review` preamble byte ratchet bumped from 33 KB to 34 KB to honor the gbrain-sync block and AskUserQuestion recommendation pattern that shipped in v1.25.1.0/v1.26.0.0. The test's own comment authorizes this exact kind of intentional-growth ratchet bump.
+- `claude-ship-SKILL.md` and `factory-ship-SKILL.md` golden fixtures regenerated against the live `/ship` template (canonical `Recommendation:` line from v1.25.1.0 now reflected in the goldens).
+
 ## [1.26.0.0] - 2026-05-02
 
 ## **Your coding agent now remembers everything. Every gstack skill auto-loads what you actually did.**
