* feat(gbrain-sync): queue primitives + writer shims
Adds bin/gstack-brain-enqueue (atomic append to sync queue) and
bin/gstack-jsonl-merge (git merge driver, ts-sort with SHA-256 fallback).
Wires one backgrounded enqueue call into learnings-log, timeline-log,
review-log, and developer-profile --migrate. question-log and
question-preferences stay local per Codex v2 decision.
gstack-config gains gbrain_sync_mode (off/artifacts-only/full) and
gbrain_sync_mode_prompted keys, plus GSTACK_HOME env alignment so
tests don't leak into real ~/.gstack/config.yaml.
* feat(gbrain-sync): --once drain + secret scan + push
bin/gstack-brain-sync is the core sync binary. Subcommands: --once
(drain queue, allowlist-filter, privacy-class-filter, secret-scan
staged diff, commit with template, push with fetch+merge retry),
--status, --skip-file <path>, --drop-queue --yes, --discover-new
(cursor-based detection of artifact writes that skip the shim).
Secret regex families: AWS keys, GitHub tokens (ghp_/gho_/ghu_/ghs_/
ghr_/github_pat_), OpenAI sk-, PEM blocks, JWTs, bearer-token-in-JSON.
On hit: unstage, preserve queue, print remediation hint (--skip-file
or edit), exit clean. No daemon — invoked by preamble at skill
boundaries.
* feat(gbrain-sync): init, restore, uninstall, consumer registry
bin/gstack-brain-init: idempotent first-run. git init ~/.gstack/,
.gitignore=*, canonical .brain-allowlist + .brain-privacy-map.json,
pre-commit secret-scan hook (defense-in-depth), merge driver registration
via git config, gh repo create --private OR arbitrary --remote <url>,
initial push, ~/.gstack-brain-remote.txt for new-machine discovery,
GBrain consumer registration via HTTP POST.
bin/gstack-brain-restore: safe new-machine bootstrap. Refuses clobber
of existing allowlisted files, clones to staging, rsync-copies tracked
files, re-registers merge drivers (required — not cloned from remote),
rehydrates consumers.json, prompts for per-consumer tokens.
bin/gstack-brain-uninstall: clean off-ramp. Removes .git + .brain-*
files + consumers.json + config keys. Preserves user data (learnings,
plans, retros, profile). Optional --delete-remote for GitHub repos.
bin/gstack-brain-consumer + bin/gstack-brain-reader (symlink alias):
registry management. Internal 'consumer' term; user-facing 'reader'
per DX review decision.
* feat(gbrain-sync): preamble block — privacy gate + boundary sync
scripts/resolvers/preamble/generate-brain-sync-block.ts emits bash that
runs at every skill invocation:
- Detects ~/.gstack-brain-remote.txt on machines without local .git
and surfaces a restore-available hint (does NOT auto-run restore).
- Runs gstack-brain-sync --once at skill start to drain any pending
writes (and at skill end via prose instruction).
- Once-per-day auto-pull (cached via .brain-last-pull) for append-only
JSONL files.
- Emits BRAIN_SYNC: status line every skill run.
Also emits prose for the host LLM to fire the one-time privacy
stop-gate (full / artifacts-only / off) when gbrain is detected and
gbrain_sync_mode_prompted is false. Wired into preamble.ts composition.
* test(gbrain-sync): 27-test consolidated suite
test/brain-sync.test.ts covers:
- Config: validation, defaults, GSTACK_HOME env isolation
- Enqueue: no-op gates, skip list, concurrent atomicity, JSON escape
- JSONL merge driver: 3-way + ts-sort + SHA-256 fallback
- Init + sync: canonical file creation, merge driver registration,
push-reject + fetch+merge retry path
- Init refuses different remote (idempotency)
- Cross-machine restore round-trip (machine A write → machine B sees)
- Secret scan across all 6 regex families (AWS, GH, OpenAI, PEM, JWT,
bearer-JSON). --skip-file unblock remediation
- Uninstall removes sync config, preserves user data
- --discover-new idempotence via mtime+size cursor
Behaviors verified via integration smokes during implementation. Known
follow-up: bun-test 5s default timeout needs 30s wrapper for
spawnSync-heavy tests.
* docs(gbrain-sync): user guide + error lookup + README section
docs/gbrain-sync.md: setup walkthrough, privacy modes, cross-machine
workflow, secret protection, two-machine conflict handling, uninstall,
troubleshooting reference.
docs/gbrain-sync-errors.md: problem/cause/fix index for every
user-visible error. Patterned on Rust's error docs + Stripe's API
error reference.
README.md: 'Cross-machine memory with GBrain sync' section near the
top (discovery moment), plus docs-table entry.
* chore: bump version and changelog (v1.7.0.0)
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* chore: regenerate SKILL.md files for gbrain-sync preamble block
Re-runs bun run gen:skill-docs after adding generateBrainSyncBlock
to scripts/resolvers/preamble.ts in a2aa8a07. CI check-freshness
caught the drift. All 36 SKILL.md files regenerated with the new
skill-start bash block + privacy-gate prose + skill-end sync
instructions baked in.
* fix(test): session-awareness reads AskUserQuestion Format from a Tier 2+ SKILL.md
The test was reading ROOT/SKILL.md (browse skill, Tier 1) which never
contained '## AskUserQuestion Format' — that section is only emitted
for Tier 2+ skills by scripts/resolvers/preamble.ts. As a result the
agent was prompted with an empty format guide and only emitted
'RECOMMENDATION' intermittently, making the test flaky.
Pre-existing on main (same ROOT/SKILL.md shape there) — surfaced now
because the agent run didn't hit the RECOMMENDATION/recommend/option a
fallback strings in this particular attempt.
Fix: read from office-hours/SKILL.md (Tier 3, always has the section)
with a fallback that scans for the first top-level skill dir whose
SKILL.md contains the header. Future template moves won't break this
test again.
* chore: bump to v1.9.0.0 for gbrain-sync landing
Changes just the VERSION + package.json + CHANGELOG header (1.7.0.0 → 1.9.0.0
and date 2026-04-22 → 2026-04-23). No code changes. User call: land gbrain-sync
as a bigger-signal release above main's 1.6.4.0, skipping 1.8.0.0.

# gstack-brain-enqueue — atomically append a path to the GBrain sync queue.
|
|
#
|
|
# Usage:
|
|
# gstack-brain-enqueue <file-path>
|
|
#
|
|
# Called by writer scripts (gstack-learnings-log, gstack-timeline-log, etc.)
|
|
# after their local write. Fire-and-forget; failures are silent (never blocks
|
|
# the writer). Queue is drained by `gstack-brain-sync --once` invoked from the
|
|
# preamble at skill START and END boundaries.
|
|
#
|
|
# No-op when:
|
|
# - gbrain_sync_mode is off (the default)
|
|
# - ~/.gstack/.git doesn't exist (feature not initialized)
|
|
# - <file-path> matches a line in ~/.gstack/.brain-skip.txt
|
|
#
|
|
# Env:
|
|
# GSTACK_HOME — override ~/.gstack state directory (aligns with writers).
|
|
# Tests use GSTACK_HOME=/tmp/test-$$ for isolation.
|
|
#
|
|
# Concurrency: POSIX append is atomic up to PIPE_BUF (~4KB Linux, 512 BSD).
|
|
# Queue lines are ~200 bytes, safe under concurrent callers.
|
|
|
|
# No `-e` — writer shims rely on this never failing loudly.
