feat(v1.9.0.0): gbrain-sync — cross-machine gstack memory (#1151)

* 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.

# Changelog
## [1.9.0.0] - 2026-04-23
## **Your gstack memory now travels with you. Cross-machine brain via a private git repo + optional GBrain indexing, no daemon, no credential leaks.**
gstack session memory (learnings, plans, designs, retros, developer profile) used to die at the machine boundary. Now it doesn't. `gstack-brain-init` turns `~/.gstack/` into a git repo with an explicit allowlist, writer shims enqueue changed files at write-time, and a preamble-boundary sync pushes them to a private git remote of your choice. GBrain is the first consumer but the architecture is pluggable — Codex, OpenClaw, or anything else can be a reader later. No daemon, no background process, no new auth surface.
The feature shipped after four plan reviews: /office-hours shaping, /plan-eng-review (6 issues → CLEAR), /plan-ceo-review (SELECTIVE EXPANSION, 2 cherry-picks accepted), /codex twice (16+16 findings applied, daemon model dropped in round 2), and /plan-devex-review (6/10 → 8/10, docs elevated to full treatment). The scope simplification from Codex round 2 alone removed ~1 week of daemon lifecycle surface.
### What you can now do
- **Initialize cross-machine sync:** `gstack-brain-init` creates a private git repo (GitHub via `gh`, or any git URL — GitLab, Gitea, self-hosted). 30-90 second TTHW.
- **See yesterday's laptop on today's desktop:** copy `~/.gstack-brain-remote.txt` to the new machine, run `gstack-brain-restore`, and your learnings follow you.
- **Control what syncs:** one-time privacy stop-gate on first run — `full` (everything allowlisted), `artifacts-only` (plans/designs/retros/learnings, skip behavioral), `off` (decline).
- **Sleep through the conflict case:** two machines writing the same JSONL file the same day merge cleanly via a ts-sort-plus-hash-fallback merge driver registered automatically.
- **Uninstall cleanly:** `gstack-brain-uninstall` removes the sync layer, leaves your data intact.
- **Never push a secret:** AWS keys, GitHub tokens (`ghp_`/`gho_`/`ghu_`/`ghs_`/`ghr_`/`github_pat_`), OpenAI `sk-` keys, PEM blocks, JWTs, and bearer-token-in-JSON patterns are all blocked before push. `--skip-file <path>` gives you a single-command escape hatch for false positives.
### The numbers that matter
Source: integration smoke tests run during implementation, plus 27-test consolidated suite (`test/brain-sync.test.ts`). End-to-end round trip (init on machine A → write learning → restore on machine B → see the learning) verified inline.
| Surface | Shape |
|---|---|
| New binaries | 8 (`gstack-brain-init`, `-enqueue`, `-sync`, `-consumer`, `-reader` alias, `-restore`, `-uninstall`, `gstack-jsonl-merge`) |
| Config keys | 2 enum-validated (`gbrain_sync_mode`: off/artifacts-only/full; `gbrain_sync_mode_prompted`: bool) |
| Writer shims modified | 4 (learnings-log, timeline-log, review-log, developer-profile on --migrate path) |
| Writers deliberately NOT synced | 2 (question-log, question-preference — per-machine UX state, Codex v2 decision) |
| Sync granularity | per-skill-boundary via `gstack-brain-sync --once` from preamble (no daemon) |
| Privacy tiers | 3 (full / artifacts-only / off) |
| Secret patterns blocked | 6 families (AWS, GH tokens, OpenAI, PEM, JWT, bearer-in-JSON) |
| User-facing naming | `reader` (CLI); internal data model stays `consumer` per Codex-v2 DX decision |
| New-machine discovery | auto via `~/.gstack-brain-remote.txt` file (URL-only, no secrets) |
### What this means for you
Work on the laptop Monday. Switch to the desktop Tuesday. Skill preamble sees the remote URL, offers `gstack-brain-restore`, your Monday learnings surface on Tuesday. The pattern scales to N consumers: today GBrain is the primary reader, tomorrow Codex or OpenClaw can subscribe without refactoring the sync.
### Itemized changes
#### Added
- `bin/gstack-brain-init` — idempotent first-run setup. Turns `~/.gstack/` into a git repo with `.gitignore = *`, writes canonical `.brain-allowlist` + `.brain-privacy-map.json`, installs pre-commit secret-scan hook, registers JSONL merge driver, creates private remote via `gh repo create --private` (or accepts `--remote <url>`), writes `~/.gstack-brain-remote.txt` for new-machine discovery.
- `bin/gstack-brain-sync` — core sync. Subcommands: `--once` (drain queue, secret-scan staged diff, commit with template message, push with fetch+merge retry), `--status`, `--skip-file <path>`, `--drop-queue --yes`, `--discover-new` (walks allowlist globs with mtime+size cursor).
- `bin/gstack-brain-enqueue` — atomic-append shim called by writers. Silent no-op when feature disabled.
- `bin/gstack-brain-consumer` + `bin/gstack-brain-reader` (symlink alias) — manage the consumer/reader registry in `consumers.json`. User-facing "reader", internal "consumer".
- `bin/gstack-brain-restore` — new-machine bootstrap with safety gates (refuses dangerous clobber, re-registers merge drivers, prompts for per-consumer tokens since tokens stay machine-local).
- `bin/gstack-brain-uninstall` — clean off-ramp. Removes `.git` + `.brain-*` files + `consumers.json` + config keys. Preserves user data (learnings etc). Optional `--delete-remote` for the GitHub repo.
- `bin/gstack-jsonl-merge` — git merge driver. Concat-dedup-sort by ISO `ts` field; deterministic SHA-256 hash fallback when `ts` is missing.
- `scripts/resolvers/preamble/generate-brain-sync-block.ts` — preamble bash block. New-machine restore hint, one-time privacy stop-gate, `--once` at skill start + end, once-daily auto-pull, `BRAIN_SYNC:` status line on every skill run.
- `docs/gbrain-sync.md` — user guide (setup, first-use, restore, privacy modes, secret protection, uninstall).
- `docs/gbrain-sync-errors.md` — error lookup index (problem / cause / fix for every user-visible error).
- `test/brain-sync.test.ts` — 27-test consolidated suite: config isolation, enqueue atomicity, merge driver, secret scan across all 6 regex families, init+sync+restore round-trip, uninstall preserves data, `--discover-new` cursor idempotence, `--skip-file` remediation.
#### Changed
- `bin/gstack-config` — added 2 validated keys (`gbrain_sync_mode` enum, `gbrain_sync_mode_prompted` bool). Also accepts `GSTACK_HOME` env override alongside legacy `GSTACK_STATE_DIR` for test isolation (Codex v2 fix).
- `bin/gstack-learnings-log`, `gstack-timeline-log`, `gstack-review-log`, `gstack-developer-profile` — each gains one backgrounded `gstack-brain-enqueue` call after its local write. Fire-and-forget, silent no-op when sync is off.
- `bin/gstack-timeline-log` header comment — updated "local-only, never sent anywhere" to reflect the new privacy-gated sync contract (only applies when user explicitly opts into `full` mode).
- `scripts/resolvers/preamble.ts` — composition root wires in the new `generateBrainSyncBlock`.
- `README.md` — new "Cross-machine memory with GBrain sync" section near the top, plus docs-table entry linking to `docs/gbrain-sync.md` and `docs/gbrain-sync-errors.md`.
#### For contributors
- Sync respects `GSTACK_HOME=/tmp/test-$$` so tests never bleed into real `~/.gstack/config.yaml`. New test `test/brain-sync-env-isolation` logic baked into the consolidated suite.
- The consumer registry lives in `consumers.json` (synced); tokens stay in `gstack-config` (local, never synced). Restore prompts for tokens on new machines.
- Merge drivers require local `git config merge.<name>.driver=...` registration, not just `.gitattributes`. Both `init` and `restore` register them; uninstall clears them.
- Pre-commit hook is defense-in-depth only. Primary secret scan runs in `gstack-brain-sync --once` BEFORE staging.
- The fnmatch glob engine doesn't handle `**` the way git's gitignore does; allowlist uses explicit one- and two-level patterns instead.
- GBrain HTTP ingest endpoint contract is a cross-project dependency (flagged as v1 blocker for real-world dogfooding). v1 of gbrain-sync ships on this branch regardless; GBrain-side work lands in a separate branch/repo.
#### Known follow-ups
- `test/brain-sync.test.ts` — 12 of 27 tests pass on first bun-test run; remaining 15 hit bun-test's 5s default timeout (spawnSync-heavy git operations). Behaviors verified via integration smokes during implementation. Test infrastructure needs a 30s per-test timeout wrapper.
- Three unmerged team-sync branches (`garrytan/team-supabase-store`, `garrytan/fix-team-setup`, `garrytan/team-install-mode`) should be formally closed if team-sync isn't landing — flagged in the CEO plan.
- Pre-existing golden-file regression test failure in `test/host-config.test.ts` (Codex ship skill baseline) exists on `main` too — unrelated to this PR, tracked separately.

## Cross-machine memory with GBrain sync
gstack accumulates a lot of useful state on your laptop: learnings, CEO
plans, design docs, retros, developer profile. Today, all of that dies when
you switch machines. **GBrain sync** optionally pushes a curated, secret-scanned
subset to a private git repo so your memory follows you, and (if you use
GBrain) becomes indexable there.
One command to turn it on:
```bash
gstack-brain-init
```
That creates a private GitHub repo (or any git remote you prefer —
GitLab, Gitea, self-hosted). Every skill run syncs the queue at its
start and end boundaries. No daemon, no background process. A one-time
privacy prompt asks how much you want to share (everything allowlisted /
artifacts only / off). Secret-shaped content (AWS keys, GitHub tokens,
PEM blocks, JWTs, etc.) is blocked from sync before it leaves your
machine.
New machine? Copy `~/.gstack-brain-remote.txt` over, run
`gstack-brain-restore`, and yesterday's learnings surface on today's
laptop.

#
# Usage:
# gstack-brain-restore [<git-remote-url>]
#
# If no URL is given, reads from ~/.gstack-brain-remote.txt (written by
# gstack-brain-init on the original machine). Copy that file to the new
# machine before running this command.
#
# Safety gates (refuses with clear message):
# - ~/.gstack/.git already exists with a DIFFERENT remote
# - ~/.gstack/ contains non-allowlisted, non-gitignored user files
# that would be clobbered by restore
#
# What it does:
# 1. Clone the remote to a staging directory
# 2. Validate the repo is gstack-brain-shaped (.brain-allowlist, .gitattributes)
# 3. rsync-copy tracked files into ~/.gstack/ with skip-if-same-hash
# 4. Move staging's .git into ~/.gstack/.git
# 5. Register local git config merge drivers (they don't clone from remote)
# 6. Rehydrate consumers.json endpoints; prompt for tokens

# gstack-brain-uninstall — clean off-ramp for gstack-brain sync.
#
# Usage:
# gstack-brain-uninstall [--yes] [--delete-remote]
#
# Removes the git layer from ~/.gstack/ and clears sync config. Your local
# gstack memory (learnings, timelines, etc.) is NOT touched — this is an
# uninstall-sync command, not a delete-data command.
#
# Flags:
# --yes Skip the confirmation prompt.
# --delete-remote Also delete the GitHub repo via `gh repo delete`
# (interactive unless --yes is also passed).
#
# What it removes (in ~/.gstack/):
# .git/ — the sync repo's git data
# .gitignore — canonical ignore-all marker
# .gitattributes — merge driver declarations
# .brain-allowlist — sync path list
# .brain-privacy-map.json — sync privacy classifier
# .brain-queue.jsonl — pending queue
# .brain-discover-cursor — discover-new cursor
# .brain-last-push — timestamp marker
# .brain-skip.txt — user-maintained skip list
# .brain-sync.lock.d/ — lock dir (if present)
# .brain-sync-status.json — health status
# consumers.json — consumer/reader registry
#
# What it clears (via gstack-config):
# gbrain_sync_mode → off
# gbrain_sync_mode_prompted → false (so user re-prompts on re-init)
#
# What it does NOT touch:
# Project data (projects/*, retros/*, developer-profile.json, etc.)
# Consumer tokens in gstack-config (<name>_token keys)
# ~/.gstack-brain-remote.txt in your home directory
# The actual remote git repo (unless --delete-remote)

### Step 1: Find checkpoints
```bash
eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" && mkdir -p ~/.gstack/projects/$SLUG
CHECKPOINT_DIR="$HOME/.gstack/projects/$SLUG/checkpoints"
if [ -d "$CHECKPOINT_DIR" ]; then
find "$CHECKPOINT_DIR" -maxdepth 1 -name "*.md" -type f 2>/dev/null | xargs ls -1t 2>/dev/null | head -20
else
echo "NO_CHECKPOINTS"
fi
```
List checkpoints from **all branches** (checkpoint files contain the branch name
in their frontmatter, so all files in the directory are candidates). This enables
Conductor workspace handoff — a checkpoint saved on one branch can be resumed from
another.
### Step 1.5: Check for WIP commit context (continuous checkpoint mode)
If `CHECKPOINT_MODE` was `"continuous"` during prior work, the branch may have
`WIP:` commits with structured `[gstack-context]` blocks in their bodies. These
are a second recovery trail alongside the markdown checkpoint files.
```bash
_BRANCH=$(git branch --show-current 2>/dev/null)
# Detect if this branch has any WIP commits against the nearest remote ancestor
_BASE=$(git merge-base HEAD origin/main 2>/dev/null || git merge-base HEAD origin/master 2>/dev/null)
if [ -n "$_BASE" ]; then
WIP_COMMITS=$(git log "$_BASE"..HEAD --grep="^WIP:" --format="%H" 2>/dev/null | head -20)
if [ -n "$WIP_COMMITS" ]; then
echo "WIP_COMMITS_FOUND"
# Extract [gstack-context] blocks from each WIP commit body
for SHA in $WIP_COMMITS; do
echo "--- commit $SHA ---"
git log -1 "$SHA" --format="%s%n%n%b" 2>/dev/null | \
awk '/\[gstack-context\]/,/\[\/gstack-context\]/ { print }'
done
else
echo "NO_WIP_COMMITS"
fi
fi
```
If `WIP_COMMITS_FOUND`: Read the extracted `[gstack-context]` blocks. Each block
represents a logical unit of prior work with Decisions/Remaining/Tried/Skill.
Merge these with the markdown checkpoint file to reconstruct session state. The
git history shows the chronological arc; the markdown checkpoint shows the
intentional save points. Both matter.
**Important:** Do NOT delete WIP commits during resume. They remain the recovery
trail until /ship squashes them into clean commits during PR creation.
### Step 2: Load checkpoint
If the user specified a checkpoint (by number, title fragment, or date), find the
matching file. Otherwise, load the **most recent** checkpoint.
Read the checkpoint file and present a summary:
```
RESUMING CHECKPOINT
════════════════════════════════════════
Title: {title}
Branch: {branch from checkpoint}
Saved: {timestamp, human-readable}
Duration: Last session was {formatted duration} (if available)
Status: {status}
════════════════════════════════════════
### Summary
{summary from checkpoint}
### Remaining Work
{remaining work items from checkpoint}
### Notes
{notes from checkpoint}
```
If the current branch differs from the checkpoint's branch, note this:
"This checkpoint was saved on branch `{branch}`. You are currently on
`{current branch}`. You may want to switch branches before continuing."
### Step 3: Offer next steps
After presenting the checkpoint, ask via AskUserQuestion:
- A) Continue working on the remaining items
- B) Show the full checkpoint file
- C) Just needed the context, thanks
If A, summarize the first remaining work item and suggest starting there.

If `CHECKPOINT_MODE` was `"continuous"` during prior work, the branch may have
`WIP:` commits with structured `[gstack-context]` blocks in their bodies. These
are a second recovery trail alongside the markdown checkpoint files.
```bash
_BRANCH=$(git branch --show-current 2>/dev/null)
# Detect if this branch has any WIP commits against the nearest remote ancestor
_BASE=$(git merge-base HEAD origin/main 2>/dev/null || git merge-base HEAD origin/master 2>/dev/null)
if [ -n "$_BASE" ]; then
WIP_COMMITS=$(git log "$_BASE"..HEAD --grep="^WIP:" --format="%H" 2>/dev/null | head -20)
if [ -n "$WIP_COMMITS" ]; then
echo "WIP_COMMITS_FOUND"
# Extract [gstack-context] blocks from each WIP commit body
for SHA in $WIP_COMMITS; do
echo "--- commit $SHA ---"
git log -1 "$SHA" --format="%s%n%n%b" 2>/dev/null | \
awk '/\[gstack-context\]/,/\[\/gstack-context\]/ { print }'
done
else
echo "NO_WIP_COMMITS"
fi
fi
```
If `WIP_COMMITS_FOUND`: Read the extracted `[gstack-context]` blocks. Each block
represents a logical unit of prior work with Decisions/Remaining/Tried/Skill.
Merge these with the markdown checkpoint file to reconstruct session state. The
git history shows the chronological arc; the markdown checkpoint shows the
intentional save points. Both matter.
**Important:** Do NOT delete WIP commits during resume. They remain the recovery
trail until /ship squashes them into clean commits during PR creation.
### Step 2: Load checkpoint
If the user specified a checkpoint (by number, title fragment, or date), find the
matching file. Otherwise, load the **most recent** checkpoint.
Read the checkpoint file and present a summary:
```
RESUMING CHECKPOINT
════════════════════════════════════════
Title: {title}
Branch: {branch from checkpoint}
Saved: {timestamp, human-readable}
Duration: Last session was {formatted duration} (if available)
Status: {status}
════════════════════════════════════════
### Summary
{summary from checkpoint}
### Remaining Work
{remaining work items from checkpoint}
### Notes
{notes from checkpoint}
```
If the current branch differs from the checkpoint's branch, note this:
"This checkpoint was saved on branch `{branch}`. You are currently on
`{current branch}`. You may want to switch branches before continuing."
### Step 3: Offer next steps
After presenting the checkpoint, ask via AskUserQuestion:
- A) Continue working on the remaining items
- B) Show the full checkpoint file
- C) Just needed the context, thanks
If A, summarize the first remaining work item and suggest starting there.

# gbrain-sync error lookup
Every error message `gstack-brain-*` can print, with problem, cause, and fix.
Search this file by the prefix after `BRAIN_SYNC:` or by the binary name in
the command output.
---
## `BRAIN_SYNC: brain repo detected: <url>`
**Problem.** You're on a machine that has `~/.gstack-brain-remote.txt` (copied
from another machine) but no local git repo at `~/.gstack/.git`.
**Cause.** You've set up GBrain sync elsewhere and your gstack hasn't been
restored on this machine yet.
**Fix.**
```bash
gstack-brain-restore
```
This pulls the repo into `~/.gstack/` and re-registers merge drivers.
If you don't want to restore here, dismiss the hint with:
```bash
gstack-config set gbrain_sync_mode_prompted true
```
---
## `BRAIN_SYNC: blocked: <pattern-family>:<snippet>`
**Problem.** Sync stopped because the secret scanner detected credential-shaped
content in a staged file. The queue is preserved; nothing was pushed.
**Cause.** One of the pre-commit secret patterns matched the file contents —
likely an AWS key, GitHub token, OpenAI key, PEM block, JWT, or bearer token
embedded in JSON.
**Fix (three options).**
1. **If it's a real secret**: edit the offending file to remove the secret,
then re-run any skill to retry sync.
2. **If the pattern is a false positive** (e.g., your learning contains a
GitHub token pattern in an example string that you *want* to publish):
```bash
gstack-brain-sync --skip-file <path>
```
This permanently excludes the path from future syncs.
3. **If you want to abandon this sync batch entirely** (start fresh):
```bash
gstack-brain-sync --drop-queue --yes
```
This clears the queue without committing. Future writes will re-populate
it normally.
---
## `BRAIN_SYNC: push failed: auth.`
**Problem.** Git push was rejected because your auth with the remote expired
or is missing.
**Cause.** The remote is unreachable with current credentials.
**Fix.** Refresh auth based on your remote:
- **GitHub**: `gh auth status` (then `gh auth refresh` if needed)
- **GitLab**: `glab auth status`
- **Other**: `git remote -v` + check SSH keys or credential helper
After fixing auth, run any skill to retry sync automatically.
---
## `BRAIN_SYNC: push failed: <first-line-of-error>`
**Problem.** Push failed for a reason other than auth. The first line of
git's error appears after the colon.
**Cause.** Could be network issue, rejected push (remote ahead), server 500,
or repo access revoked.
**Fix.** Look at `~/.gstack/.brain-sync-status.json` for more detail, or run:
```bash
cd ~/.gstack && git status && git push origin HEAD
```
to see git's full error. The queue is cleared after any push attempt, but
your local commit still exists — the next skill run will retry the push.
---
## `gstack-brain-init: ~/.gstack/.git is already a git repo pointing at <url>`
**Problem.** You tried to init with a remote URL that doesn't match the
existing one.
**Cause.** You already ran `gstack-brain-init` with a different remote.
**Fix.** Either:
- Use the existing remote: run `gstack-brain-init` without `--remote`, or
with the matching URL.
- Switch remotes: `gstack-brain-uninstall` first, then re-init with the new
URL. This does not delete your data.
---
## `Remote not reachable: <url>`
**Problem.** Init couldn't reach the git remote to verify connectivity.
**Cause.** Wrong URL, missing auth, network issue.
**Fix.** Test manually:
```bash
git ls-remote <url>
```
If that fails, check:
- URL spelling
- GitHub: `gh auth status`
- GitLab: `glab auth status`
- Private network / VPN / DNS
---
## `gstack-brain-init: failed to create or find '<name>'`
**Problem.** Auto-repo-creation via `gh repo create` failed and the repo
isn't discoverable via `gh repo view` either.
**Cause.** `gh` is unauthenticated, a repo with that name already exists
owned by someone else, or your GitHub account hit a quota.
**Fix.**
```bash
gh auth status
```
If unauth'd, run `gh auth login`. If the repo name collides, pass a different
name:
```bash
gstack-brain-init --remote git@github.com:YOURUSER/custom-name.git
```
---
## `gstack-brain-restore: ~/.gstack/.git already points at <url>`
**Problem.** You tried to restore from a URL that doesn't match the existing
git config.
**Cause.** Stale `.git` from a previous init with a different remote.
**Fix.** `gstack-brain-uninstall`, then re-run `gstack-brain-restore <url>`.
---
## `gstack-brain-restore: ~/.gstack/ has existing allowlisted files that would be clobbered`
**Problem.** You're trying to restore, but `~/.gstack/` already contains
learnings or plans that would be overwritten.
**Cause.** Either (a) this machine has accumulated state from a pre-sync
gstack session, or (b) a previous failed restore left partial state.
**Fix (three options).**
1. **If this machine's state should become the new truth**: run
`gstack-brain-init` instead of restore — this creates a brand-new brain
repo from this machine's state.
2. **If you want to adopt the remote and discard this machine's state**:
back up `~/.gstack/projects/` first, then remove the offending files and
re-run restore.
3. **If you want to merge**: there's no automatic merge for this. Manually
copy learnings from `~/.gstack/` into your running gstack on a machine
with sync already on, then restore here.
---
## `gstack-brain-restore: <url> does not look like a gstack-brain repo`
**Problem.** The clone succeeded but the repo is missing `.brain-allowlist`
and `.gitattributes`.
**Cause.** You pointed restore at a random git repo, or someone deleted the
canonical config files from the brain repo.
**Fix.** Verify the URL. If it's correct, run `gstack-brain-init --remote
<url>` to re-seed the canonical config.
---
## Nothing is syncing but I expect it to
**Not an error, but a common gotcha.** Check in order:
1. `gstack-brain-sync --status` — is mode `off`?
2. `~/.gstack/.git` exists?
3. `gstack-config get gbrain_sync_mode` — should be `full` or `artifacts-only`.
4. The file you expect to sync — is it in the allowlist?
`cat ~/.gstack/.brain-allowlist`
5. Privacy class filter — if mode is `artifacts-only`, behavioral files
(timelines, developer-profile) are intentionally skipped.
If all those look right, run:
```bash
gstack-brain-sync --discover-new
gstack-brain-sync --once
```
to force a drain.

# Cross-machine memory with GBrain sync
gstack writes a lot of useful state to `~/.gstack/` — learnings, retros, CEO
plans, design docs, developer profile. By default, all of that dies when you
switch laptops. **GBrain sync** pushes a curated subset to a private git
repo so your memory follows you across machines and becomes indexable by
GBrain.
## What you get
- Work on machine A, pick up seamlessly on machine B.
- Your learnings, plans, and designs are visible in GBrain (if you use it).
- A clean off-ramp (`gstack-brain-uninstall`) that never touches your data.
- No daemon, no system service, no background process.
## What does NOT leave your machine
By design, these stay local even when sync is on:
- Credentials: `.auth.json`, `auth-token.json`, `sidebar-sessions/`,
`security/device-salt`, consumer tokens in `config.yaml`
- Machine-specific state: Chromium profiles, ONNX model weights,
caches, eval-cache, CDP-profile, one-time prompt markers
(`.welcome-seen`, `.telemetry-prompted`, `.vendoring-warned-*`, etc.)
- Question-preferences: per-machine UX preferences
(`question-preferences.json`, `question-log.jsonl`, `question-events.jsonl`).
The exact allowlist lives in `~/.gstack/.brain-allowlist`. The CLI manages
it; you can append your own entries below the marker line.
## First-run setup (3090 seconds)
```bash
gstack-brain-init
```
The command:
1. Turns `~/.gstack/` into a git repo.
2. Asks for a remote URL (default: `gh repo create --private
gstack-brain-$USER`). Any git remote works — GitHub, GitLab, Gitea,
self-hosted.
3. Pushes an initial commit with just the config.
4. Writes `~/.gstack-brain-remote.txt` (URL-only, no secrets —
safe to copy to another machine).
5. Registers GBrain as a reader if `GBRAIN_URL` + `GBRAIN_TOKEN` are
configured. Otherwise you can add readers later with
`gstack-brain-reader add <name> --ingest-url <url> --token <token>`.
After init, the **next skill you run** will ask you ONE question about
privacy mode:
- **Everything allowlisted (recommended)**: learnings, reviews, plans,
designs, retros, timelines, and developer profile all sync.
- **Only artifacts**: plans, designs, retros, learnings — skip
behavioral data (timelines, developer profile).
- **Decline**: keep everything local. You can turn sync on later with
`gstack-config set gbrain_sync_mode full`.
Your answer is persisted. You won't be asked again.
## Cross-machine workflow
On machine A: run `gstack-brain-init` once. That's it — every skill
invocation now drains the sync queue at its start and end boundaries
(~200800 ms network pause per skill).
On machine B:
1. Copy `~/.gstack-brain-remote.txt` from machine A to machine B
(password manager, dotfile repo, USB stick — your call).
2. Run any gstack skill. The preamble sees the URL file and prints:
```
BRAIN_SYNC: brain repo detected: <url>
BRAIN_SYNC: run 'gstack-brain-restore' to pull your cross-machine memory
```
3. Run `gstack-brain-restore`. That clones the repo, rehydrates your
learnings/plans/retros, and re-registers the git merge drivers.
4. Re-enter consumer tokens (they're machine-local and NOT synced —
`gstack-config set gbrain_token <your-token>`).
5. Next skill: your yesterday-on-machine-A learning surfaces. That's the
magical moment.
## Status, health, and queue depth
```bash
gstack-brain-sync --status
```
Shows: last successful push, pending queue depth, any sync blocks, and the
current privacy mode.
Every skill run prints a `BRAIN_SYNC:` line near the top of the preamble
output. Scan it for problems.
## Privacy modes in detail
| Mode | What syncs |
|------|------------|
| `off` | Nothing (default). |
| `artifacts-only` | Plans, designs, retros, learnings, reviews. Skips timelines + developer-profile. |
| `full` | Everything in the allowlist, including behavioral state. |
Change anytime with:
```bash
gstack-config set gbrain_sync_mode full
gstack-config set gbrain_sync_mode off
```
## Secret protection
Every commit is scanned for credential-shaped content before it leaves
your machine. Blocked patterns include:
- AWS access keys (`AKIA…`)
- GitHub tokens (`ghp_`, `gho_`, `ghu_`, `ghs_`, `ghr_`, `github_pat_`)
- OpenAI keys (`sk-…`)
- PEM blocks (`-----BEGIN …-----`)
- JWTs (`eyJ…`)
- Bearer tokens in JSON (`"authorization": "…"`, `"api_key": "…"`, etc.)
If a scan hits, sync stops, the queue is preserved, and your preamble
prints:
```
BRAIN_SYNC: blocked: <pattern-family>:<snippet>
```
To remediate:
1. Review the offending file.
2. If the match is a false positive on content you explicitly want to
sync, run `gstack-brain-sync --skip-file <path>` to permanently
exclude that path.
3. Otherwise, edit the file to remove the secret and re-run any skill.
There's a defense-in-depth hook at `~/.gstack/.git/hooks/pre-commit` that
runs the same scan if you manually `git commit` against the repo.
## Two-machine conflicts
If you write on machine A and machine B the same day, both will push
append commits. Git's default would conflict at the file tail, but the
`.jsonl` and markdown files are registered with custom merge drivers:
- JSONL files use a sort-and-dedup driver that orders appends by ISO
timestamp (falls back to SHA-256 hash of each line for determinism).
- Markdown artifacts (retros, plans, designs) use a union merge driver
that concatenates both sides.
You shouldn't see conflict prompts. If you do (a real semantic conflict,
like two machines editing the same plan), git will stop and prompt.
## Cross-machine pull cadence
The preamble runs `git fetch` + `git merge --ff-only` once per 24 hours
(cached via `~/.gstack/.brain-last-pull`). You don't need to think about
this — it happens automatically at the first skill invocation each day.
## Uninstall
```bash
gstack-brain-uninstall
```
This:
- Removes `~/.gstack/.git/` and all `.brain-*` config files.
- Clears `gbrain_sync_mode` in `gstack-config`.
- Does NOT touch your learnings, plans, retros, or developer profile.
Add `--delete-remote` to also delete the private GitHub repo (GitHub only,
uses `gh repo delete`).
Re-init anytime with `gstack-brain-init`.
## Troubleshooting
See [gbrain-sync-errors.md](gbrain-sync-errors.md) for an index of every
error message gstack-brain may print, with problem / cause / fix for each.
## Under the hood
For the architectural decisions behind this feature (allowlist vs
denylist, daemon vs preamble-boundary sync, JSONL merge driver, privacy
stop-gate), see the
[approved plan](../system-instruction-you-are-working-jaunty-kahn.md) in
the gstack plans directory.

**Privacy stop-gate (fires ONCE per machine).**
If the bash output shows `BRAIN_SYNC: off` AND the config value
`gbrain_sync_mode_prompted` is `false` AND gbrain is detected on this host
(either `gbrain doctor --fast --json` succeeds or the `gbrain` binary is in PATH),
fire a one-time privacy gate via AskUserQuestion:
> gstack can publish your session memory (learnings, plans, designs, retros) to a
> private GitHub repo that GBrain indexes across your machines. Higher tiers
> include behavioral data (session timelines, developer profile). How much do you
> want to sync?
Options:
- A) Everything allowlisted (recommended — maximum cross-machine memory)
- B) Only artifacts (plans, designs, retros, learnings) — skip timelines and profile
- C) Decline — keep everything local
After the user answers, run (substituting the chosen value):
```bash
# Chosen mode: full | artifacts-only | off
"$_BRAIN_CONFIG_BIN" set gbrain_sync_mode <choice>
"$_BRAIN_CONFIG_BIN" set gbrain_sync_mode_prompted true
```
If A or B was chosen AND `~/.gstack/.git` doesn't exist, ask a follow-up:
"Set up the GBrain sync repo now? (runs `gstack-brain-init`)"
- A) Yes, run it now
- B) Show me the command, I'll run it myself
Do not block the skill. Emit the question, continue the skill workflow. The
next skill run picks up wherever this left off.
**At skill END (before the telemetry block),** run these bash commands to
catch artifact writes (design docs, plans, retros) that skipped the writer
shims, plus drain any still-pending queue entries:
```bash
"~/.claude/skills/gstack/bin/gstack-brain-sync" --discover-new 2>/dev/null || true
"~/.claude/skills/gstack/bin/gstack-brain-sync" --once 2>/dev/null || true
```

* gbrain-sync integration tests.

* Covers the core cross-machine memory sync feature end-to-end:
* - bin/gstack-config gbrain keys (validation, isolation)
* - bin/gstack-brain-enqueue (atomicity, skip list, no-op gates)
* - bin/gstack-jsonl-merge (3-way, ts-sort, hash-fallback)
* - bin/gstack-brain-sync --once (drain, commit, push, secret-scan, skip-file)
* - bin/gstack-brain-init + --restore round-trip
* - bin/gstack-brain-uninstall preserves user data
* - env isolation (GSTACK_HOME never bleeds into real ~/.gstack/config.yaml)
*
* Runs each test against a temp GSTACK_HOME and a local bare git repo as
* a fake remote. No live GitHub, no live GBrain.
