Garry Tan 675717e320 v1.17.0.0: setup-gbrain wireup ships the gbrain federation surface (#1234)
* feat: gstack-gbrain-source-wireup helper + 13 unit tests

The new bin/gstack-gbrain-source-wireup is the single helper that registers
the gstack brain repo as a gbrain federated source via `git worktree`, runs
incremental sync, and supports --uninstall + --probe + --strict modes.

Replaces the dead `consumers.json + ingest_url + /ingest-repo` HTTP wireup
introduced in v1.12.0.0 — that endpoint never shipped on the gbrain side.
The federation surface (`gbrain sources` / `gbrain sync`) shipped in gbrain
v0.18.0; this helper adapts to its actual semantics (no `sources update`, so
path drift recovery is `remove + re-add`; no `--install-cron` either, so
freshness rides on the existing skill-end push hook).

Source-id derivation is multi-fallback: ~/.gstack/.git origin URL →
~/.gstack-brain-remote.txt → --source-id flag. This makes `--uninstall`
work even after `~/.gstack/.git` is destroyed by the parent uninstall script.

Worktree is `--detach`ed at $GSTACK_HOME's HEAD because main is already
checked out there; advance is a re-checkout of the parent's current HEAD,
not a `git pull`. Divergence recovery removes + re-adds the worktree.

Test suite covers 13 cases: fresh-state registration, idempotent re-runs,
drift recovery, --strict failure modes, source-id fallback chain, --probe
non-mutation, sync errors, and --uninstall. Fake gbrain on $PATH, real git
ops at GSTACK_HOME tmp dir.

* feat: wire setup-gbrain + brain-restore + brain-uninstall to use the helper

setup-gbrain Step 7 now invokes gstack-gbrain-source-wireup --strict after
gstack-brain-init + gbrain_sync_mode is set. Strict mode means the user sees
the failure rather than silently ending up with an unwired brain.

bin/gstack-brain-init drops 60 lines of dead code: the HTTP POST to
${GBRAIN_URL}/ingest-repo, the GBRAIN_URL_VAL/GBRAIN_TOKEN_VAL probes, the
consumers.json writer, and the chore commit step. CONSUMERS_FILE variable
declaration removed. The closing message no longer points at the dead
gstack-brain-consumer add path.

bin/gstack-brain-restore drops the 18-line consumers.json token-rehydration
block (was a no-op for the only consumer that ever existed). Adds a
best-effort wireup invocation after the brain-repo clone so 2nd-Mac restore
gets gbrain federation automatically. Failure prints a stderr WARNING but
does not abort the restore — restore's primary job is the git clone.

bin/gstack-brain-uninstall calls the helper's --uninstall mode (which
removes the gbrain source registration, the git worktree, and the
future-launchd-plist stub) before the existing legacy consumers.json
removal. Ordering is fragile-by-design: helper derives source-id via
multi-fallback so it works even after .git is destroyed.

bin/gstack-brain-consumer gets a DEPRECATED header note. Stays in the tree
for one cycle of grace; removal in v1.13.0.0.

setup-gbrain/SKILL.md is regenerated from the .tmpl via gen:skill-docs.

* feat: v1.12.3.0 migration — wire existing brain-sync repos into gbrain

Idempotent migration script. For users who already opted into brain-sync
before this release (gbrain_sync_mode != off, ~/.gstack/.git exists), runs
the new gstack-gbrain-source-wireup helper so their existing brain repo
becomes searchable via gbrain immediately on /gstack-upgrade.

Skip conditions (each ends with exit 0):
  - HOME unset or empty (defensive)
  - gbrain_sync_mode = off or empty (user opted out)
  - no ~/.gstack/.git (brain-init never ran)
  - helper missing on disk (broken install)

No --strict on the helper invocation: missing or old gbrain is a benign
skip during a batch upgrade rather than a blocker.

* v1.12.3.0: setup-gbrain wireup ships the gbrain federation surface

Bumps VERSION 1.12.2.0 → 1.12.3.0 with a release-notes-format entry in
CHANGELOG.md. After upgrade, the placeholder consumers.json wireup is gone,
gbrain sources + sync + skill-end hook is the new path, your gstack memory
is actually searchable in gbrain.

The CHANGELOG entry follows the release-summary format from CLAUDE.md:
two-line bold headline, lead paragraph naming what shipped, "verify after
upgrade" command block readers can run on their own brain to see the
delta, then the standard Itemized changes / What this means / For
contributors sections.

Three pre-existing test failures on this branch are flagged in the
contributor section: the GSTACK_HOME isolation test (reads Garry's actual
~/.gstack/config.yaml), the 2MB tracked-binary test (security-bench
fixtures > 2MB), and the Opus 4.7 pacing-directive test (overlay text
drifted). All three were verified to fail on the base branch too — out
of scope for this PR, follow-up needed.

* feat: helper locks GBRAIN_DATABASE_URL at startup, defends against config rewrites

The wireup helper previously read ~/.gbrain/config.json on every gbrain
subprocess invocation. On Garry's Mac, multiple concurrent test runs and
agent integrations were rewriting that file mid-sync, redirecting the
wireup at the wrong brain partway through a 4-min initial import.

This commit adds a `--database-url <url>` flag to the helper and locks
the URL at startup. Precedence:
  1. --database-url flag                       (explicit caller intent)
  2. GBRAIN_DATABASE_URL / DATABASE_URL env    (CI / manual override)
  3. read once from ~/.gbrain/config.json      (default)

Whichever wins gets exported as GBRAIN_DATABASE_URL for every child
`gbrain` invocation. Per gbrain's loadConfig at src/core/config.ts:53,
env-var URLs override the file URL — so a process that flips config.json
between two of our gbrain calls can't redirect us. Defense-in-depth:
once the URL is locked, the wireup completes against the original brain
even under hostile filesystem conditions.

setup-gbrain/SKILL.md.tmpl Step 7 now reads the URL out of config.json
once (via python3 inline) and passes it explicitly with --database-url,
so even the very first wireup call is decoupled from config.json mutability.

Three new test cases cover the lock behavior:
  - --database-url flag is exported to child gbrain calls
  - falls back to ~/.gbrain/config.json when no flag and no env
  - flag overrides env GBRAIN_DATABASE_URL and config.json values

The fake gbrain in the test suite now records GBRAIN_DATABASE_URL alongside
each call so tests can assert the helper exported the locked URL.

Total test count: 13 → 16 passing.

* chore: bump v1.12.3.0 references to v1.15.1.0 to match merged-with-main release

Internal-only renames after merging origin/main bumped this branch's release
target from v1.12.3.0 → v1.15.1.0:

- gstack-upgrade/migrations/v1.12.3.0.sh → v1.15.1.0.sh (rename + log-prefix
  bump from "[v1.12.3.0]" to "[v1.15.1.0]")
- bin/gstack-brain-consumer header: "DEPRECATED in v1.12.3.0" → "DEPRECATED in
  v1.15.1.0"; removal target bumped from v1.13.0.0 → v1.16.0.0 (next minor
  after v1.15.1.0).
- bin/gstack-brain-uninstall: "no longer written ... since v1.12.3.0" →
  "since v1.15.1.0".

No behavior change. Test suite still 16/16 passing.

* test: 10 new cases close coverage gaps (helper defensive paths + migration)

/ship Step 7 coverage audit reported 48% (22/46 branches). Added 10 cases
covering the highest-impact gaps:

Helper (test/gstack-gbrain-source-wireup.test.ts, +3 cases → 19 total):
- --uninstall when gbrain is missing: best-effort exit 0, worktree still cleaned
- --no-pull skips HEAD advance on existing worktree (was untested)
- Stray non-git directory at worktree path is cleaned up + worktree created

Migration (test/gstack-upgrade-migration-v1_15_1_0.test.ts, NEW, 7 cases):
- HOME unset → defensive exit 0
- gbrain_sync_mode=off → exit 0 silently
- gbrain_sync_mode unset → exit 0 silently
- no ~/.gstack/.git → exit 0 silently
- helper missing on PATH → warning + exit 0
- happy path → invokes helper without --strict
- helper exits non-zero → migration prints retry hint, still exits 0 (non-blocking)

Also syncs package.json version from 1.15.0.0 → 1.15.1.0 to match VERSION
file (DRIFT_STALE_PKG repair from /ship Step 12 idempotency check; was a
manual-edit-bypass artifact from the merge step).

Coverage estimate: 48% → ~75%. Mainline + migration script + key defensive
paths all exercised. 26 tests total covering the new code surface.

* fix: pre-landing review auto-fixes (5 correctness + observability)

/ship Step 9 review surfaced 9 INFORMATIONAL findings on the new helper +
migration. Five auto-fixed with no behavior regression (26/26 tests pass):

bin/gstack-gbrain-source-wireup:
- Version compare: put floor "0.18.0" first in `sort -V` stdin so equal-or-
  greater $v always sorts to position 2. Stable across sort implementations.
- _worktree_add_detached: drop `2>/dev/null` on the `worktree add`, surface
  git's stderr through `prefix` so users see WHY adds fail (disk, perms).
- ensure_worktree: same observability fix on the `git checkout --detach` path
  during HEAD-advance, so users see the actual git error before recovery.
- do_probe: replace `[ -d X ] || [ -f X ] && set=present` (precedence trap —
  the `&&` short-circuits when the dir branch fails) with explicit if-block.
- do_probe: capture `check_source_state`'s return code explicitly via
  `set +e; ...; rc=$?; set -e`. `$?` after an `if`/`elif` chain is fragile
  under set -e and may not reach the elif under some shell versions.
- do_wireup: same explicit return-code capture for `ensure_worktree`. The
  prior `ensure_worktree || { if [ $? = 2 ]; ...` pattern relied on `$?`
  reflecting the function's return after `||`, which is implementation-defined.

gstack-upgrade/migrations/v1.15.1.0.sh:
- Trim whitespace from `gstack-config get gbrain_sync_mode` output via
  `tr -d '[:space:]'`. Trailing newlines would mis-classify "off\n" as a
  non-empty non-off mode and incorrectly invoke the helper.

Skipped findings (cosmetic / out of scope):
- `python3 -c` reads `~/.gbrain/config.json` via `expanduser` instead of
  the helper's `$GBRAIN_CONFIG` variable (cosmetic; HONORS HOME override).
- Long sync-failure error message could truncate to last N lines (cosmetic
  log readability).

* fix: adversarial review hardening (rm safety, jq probe, secret redaction, multi-Mac)

/ship Step 11 adversarial review surfaced 7 CRITICAL issues. Five fixed
inline (no behavior regression, 26/26 tests still pass):

bin/gstack-gbrain-source-wireup:

1. **rm -rf path validation** (was: F-c-CRITICAL 9/10).
   Added `safe_rm_worktree` helper that refuses any path not strictly under
   $HOME/, plus dangerous-path allowlist for /, /Users, $HOME root. Replaces
   raw `rm -rf "$WORKTREE"` calls (lines 161, 169 originally). If user sets
   GSTACK_BRAIN_WORKTREE="" or "/", the helper now dies cleanly instead of
   nuking the home dir or root.

2. **jq dependency probe** (was: F-c-CRITICAL 9/10).
   `check_source_state` now hard-fails with a clear message if jq is missing,
   instead of silently returning "absent" → re-add → die-on-duplicate. Plus
   trims whitespace from jq output (`tr -d '[:space:]'`) to defend against
   gbrain emitting `\n` for missing fields. Header comment claimed jq was a
   transitive dep; now we enforce it.

3. **Python heredoc warns on JSON parse failure** (was: F-c-CRITICAL 8/10).
   Previously `except Exception: pass` silently swallowed malformed JSON,
   leaving _locked_url empty and defeating the URL-lock defense. Now writes
   the parse error to a temp file and warns the user that the URL was not
   locked. Also passes the config path via env var (GBRAIN_CONFIG_PATH)
   instead of hardcoded `~/.gbrain/config.json`, respecting any HOME override.

4. **Multi-Mac source-id collision fix** (was: F-c-CRITICAL 9/10).
   When `check_source_state` returns 1 (source exists at different path), the
   helper used to remove + re-add. Two Macs sharing one Supabase brain would
   ping-pong the local_path metadata on every sync. Now: if the existing
   path's basename matches the local worktree's basename (likely another
   machine's local copy of the SAME brain repo), skip re-registration and
   sync against the local worktree. gbrain stores pages by content; metadata
   is informational. No more ping-pong.

5. **Redact DB URL from sync-failure error message** (was: F-c-CRITICAL 7/10).
   `gbrain sync` failures used to echo the full stderr (which can contain
   the postgres connection string with password) into the user's terminal
   and any log redirect. Now we sed-replace any `postgres://...` with
   `postgres://***REDACTED***` before the die() call, and only show the
   last 10 lines.

Bonus minor fix: `die()` now uses `$1` instead of `$*` for the warn
message, so the exit-code arg ($2) doesn't get appended to the warning text.

Acknowledged-but-deferred:
- GBRAIN_DATABASE_URL env exposure on Linux via /proc/$PID/environ. This is
  a Linux-only concern; gstack is Mac-targeted today and macOS restricts
  process env reads. Document as a follow-up if Linux support lands.
- gbrain version parser brittleness if gbrain switches to "v0.18.0" prefix.
  Defensive only; current gbrain output matches `gbrain X.Y.Z` exactly.
- bash 3.2 PIPESTATUS reliability. Tests pass on the host bash version (3.2+
  via macOS); modern bash 5.x is widely available.

* docs: sync gbrain-source-wireup helper into USING_GBRAIN + gbrain-sync

USING_GBRAIN_WITH_GSTACK.md: add gstack-gbrain-source-wireup row to the bin
helpers table — describes federation registration via `gbrain sources add` +
worktree, lists flags, calls out it replaces the dead consumers.json/ingest-repo
HTTP wireup.

docs/gbrain-sync.md: replace the `gstack-brain-reader add --ingest-url` step
in gstack-brain-init's flow (which targeted the never-shipped /ingest-repo
endpoint) with the real flow — federate via gbrain sources + worktree, point
to bin/gstack-gbrain-source-wireup.

* v1.16.1.0: rebump after queue-collision (PR #1233 took v1.16.0.0)

CI's "Check VERSION is not stale vs queue" job (job 73105686380) failed
with: "VERSION drift: PR #1234 claims v1.15.1.0 but the queue has moved —
next free slot is v1.16.1.0." PR #1233 (garrytan/browserharness) entered
the queue claiming v1.16.0.0 between when this branch's prior /ship ran
and when CI evaluated, so v1.15.1.0 is stale. Rebumping on top.

Files updated:
- VERSION                                                     1.15.1.0 → 1.16.1.0
- package.json                                                1.15.1.0 → 1.16.1.0
- CHANGELOG.md heading + Before/After columns                 1.15.1.0 → 1.16.1.0
- CHANGELOG removal target (consumers.json + config keys)     1.16.0.0 → 1.17.0.0
- gstack-upgrade/migrations/v1.15.1.0.sh                      → renamed v1.16.1.0.sh + log prefix
- bin/gstack-brain-consumer "DEPRECATED in" + "removal in"    1.15.1.0/1.16.0.0 → 1.16.1.0/1.17.0.0
- bin/gstack-brain-uninstall "since vX.Y.Z.W"                 1.15.1.0 → 1.16.1.0
- test/gstack-upgrade-migration-v1_15_1_0.test.ts             → renamed v1_16_1_0.test.ts

No behavior change. 26/26 wireup + migration tests still pass on the rename.
Full bun test suite: exit 0, 0 failures.

* v1.17.0.0: rebump again — bump-detection now classifies branch as MINOR

CI's version-stale check (job 73106360896) failed: PR #1234 claims v1.16.1.0
but the queue moved to v1.17.0.0. Root cause: bumping 1.15.1.0 → 1.16.1.0
to dodge the prior collision turned the branch's diff classification from
PATCH (1.15.0 → 1.15.1) into MINOR (1.15.0 → 1.16.x). detect-bump.ts now
sees MINOR, gstack-next-version walks the MINOR lane past #1233's
v1.16.0.0 claim, and the next free slot is v1.17.0.0.

Honestly accurate per CLAUDE.md scale-aware bumps: this branch IS a
MINOR ("substantial new capability shipped — skill, harness, command,
big refactor"). The new helper + migration + integration totals ~1200
lines added across 11 files with 26 new tests. PATCH was always the
wrong honest classification; the queue collision forced the right
answer.

Files updated:
- VERSION                                                     1.16.1.0 → 1.17.0.0
- package.json                                                1.16.1.0 → 1.17.0.0
- CHANGELOG.md heading + After column                         1.16.1.0 → 1.17.0.0
- CHANGELOG removal targets                                   1.17.0.0 → 1.18.0.0
- gstack-upgrade/migrations/v1.16.1.0.sh                      → renamed v1.17.0.0.sh + log prefix
- bin/gstack-brain-consumer "DEPRECATED in" + "removal in"    1.16.1.0/1.17.0.0 → 1.17.0.0/1.18.0.0
- bin/gstack-brain-uninstall "since vX.Y.Z.W"                 1.16.1.0 → 1.17.0.0
- test/gstack-upgrade-migration-v1_16_1_0.test.ts             → renamed v1_17_0_0.test.ts

26/26 tests still pass. No behavior change.
