v1.27.0.0 feat: /setup-gbrain Path 4 (remote MCP) + brain → artifacts rename (#1351)
* feat: gstack-gbrain-mcp-verify helper for remote MCP probe Probes a remote gbrain MCP endpoint with bearer auth. POSTs initialize, classifies failures into NETWORK / AUTH / MALFORMED with one-line remediation hints, and runs a tools/list capability probe to detect sources_add MCP support (forward-compat for when gbrain ships URL ingest). Token consumed from GBRAIN_MCP_TOKEN env, never argv. Required to set both 'application/json' AND 'text/event-stream' in Accept; that gotcha costs 10 minutes of debugging when missed (regression-tested). Live-verified against wintermute (gbrain v0.27.1). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat: gstack-artifacts-init + gstack-artifacts-url helpers artifacts-init replaces brain-init with provider choice (gh / glab / manual), per-user gstack-artifacts-$USER repo, HTTPS-canonical storage in ~/.gstack-artifacts-remote.txt, and a "send this to your brain admin" hookup printout. Always prints the command, never auto-executes — gbrain v0.26.x has no admin-scope MCP probe (codex Finding #3). artifacts-url centralizes HTTPS↔SSH/host/owner-repo conversion so callers don't each string-mangle (codex Finding #10). The remote-conflict check in artifacts-init compares at the canonical level so re-running with HTTPS input doesn't trip on a stored SSH URL for the same logical repo. The "URL form not supported" branch prints a two-line clone-then-path form for gbrain v0.26.x; the supported branch is a one-liner with --url ready for when gbrain ships URL ingest. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat: extend gstack-gbrain-detect with mcp_mode + artifacts_remote Adds two new fields to detect's JSON output: - gbrain_mcp_mode: local-stdio | remote-http | none Resolved via 3-tier fallback (codex Finding D3): claude mcp get --json → claude mcp list text-grep → ~/.claude.json jq read. If Anthropic moves the file format, the first two tiers absorb it. - gstack_artifacts_remote: HTTPS URL from ~/.gstack-artifacts-remote.txt Falls back to ~/.gstack-brain-remote.txt during the v1.27.0.0 migration window so detect doesn't return empty between upgrade and migration. Existing detect tests still pass (15/15). New 19 tests cover every fallback tier independently, plus a schema regression for /sync-gbrain compat. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat: setup-gbrain Path 4 (remote MCP) + artifacts rename Path 4 lets users paste an HTTPS MCP URL + bearer token and registers it as an HTTP-transport MCP without needing a local gbrain CLI install. The flow: - Step 2 gains a fourth option (Remote gbrain MCP) - Step 4 adds Path 4 sub-flow: collect URL, secret-read bearer, verify via gstack-gbrain-mcp-verify (NETWORK / AUTH / MALFORMED classifier) - Step 5 (local doctor), Step 7.5 (transcript ingest), Step 5a's stdio branch all skip on Path 4 - Step 5a adds an HTTP+bearer registration form: claude mcp add --transport http --header "Authorization: Bearer ..." - Step 7 renamed "session memory sync" → "artifacts sync" and now calls gstack-artifacts-init (which always prints the brain-admin hookup command — no auto-execute, codex Finding #3) - Step 8 CLAUDE.md block branches: remote-http includes URL + server version (never the token); local-stdio keeps engine + config-file - Step 9 smoke test on Path 4 prints the curl-equivalent for post-restart verification (MCP tools aren't visible mid-session) - Step 10 verdict block has separate templates per mode Idempotency: re-running with gbrain_mcp_mode=remote-http already in detect output skips Step 2 entirely and goes to verification. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor: rename gbrain_sync_mode → artifacts_sync_mode (v1.27.0.0 prep) Hard rename, no dual-read alias (codex Finding D4). The on-disk migration script (Phase C, separate commit) renames the config key in users' ~/.gstack/config.yaml and any CLAUDE.md blocks. Touched call sites: - bin/gstack-config defaults + validation + list/defaults output - bin/gstack-gbrain-detect (gstack_brain_sync_mode field still emitted with the same name for downstream-tool compat; reads new key) - bin/gstack-brain-sync, bin/gstack-brain-enqueue, bin/gstack-brain-uninstall - bin/gstack-timeline-log (comment ref) - scripts/resolvers/preamble/generate-brain-sync-block.ts: renames key, branches on gbrain_mcp_mode=remote-http to emit "ARTIFACTS_SYNC: remote-mode (managed by brain server <host>)" instead of the local mode/queue/last_push line (codex Finding #11) - bin/gstack-brain-restore + bin/gstack-gbrain-source-wireup: read ~/.gstack-artifacts-remote.txt with ~/.gstack-brain-remote.txt fallback during the migration window - bin/gstack-artifacts-init: tolerant of unrecognized URL forms (local paths, file://, self-hosted gitea) so test infrastructure and unusual remotes work without canonicalization - test/brain-sync.test.ts: gstack-brain-init → gstack-artifacts-init - test/skill-e2e-brain-privacy-gate.test.ts: artifacts_sync_mode keys - test/gen-skill-docs.test.ts: budget 35K → 36.5K for the new MCP-mode probe in the preamble resolver - health/SKILL.md.tmpl, sync-gbrain/SKILL.md.tmpl: comment + verdict line Hard delete: - bin/gstack-brain-init (replaced by bin/gstack-artifacts-init in v1.27.0.0) - test/gstack-brain-init-gh-mock.test.ts (replaced by gstack-artifacts-init.test.ts) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: regenerate SKILL.md files after artifacts-sync rename Mechanical regen via \`bun run gen:skill-docs --host all\`. All */SKILL.md files reflect the renamed config key (gbrain_sync_mode → artifacts_sync_mode), the renamed remote-helper file (~/.gstack-artifacts-remote.txt with brain fallback), the renamed init script (gstack-artifacts-init), and the new ARTIFACTS_SYNC: remote-mode status line that fires when a remote-http MCP is registered. Golden fixtures (test/fixtures/golden/*-ship-SKILL.md) refreshed to match the regenerated default-ship output. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat: v1.27.0.0 migration — gstack-brain → gstack-artifacts rename Journaled, interruption-safe migration. Six steps, each writes to ~/.gstack/.migrations/v1.27.0.0.journal on success; re-entry resumes from the next un-done step. On final success, journal is replaced by ~/.gstack/.migrations/v1.27.0.0.done. Steps: 1. gh_repo_renamed gh/glab repo rename gstack-brain-$USER → gstack-artifacts-$USER (idempotent: detects already-renamed and skips) 2. remote_txt_renamed mv ~/.gstack-brain-remote.txt → artifacts file, rewriting URL path to match the new repo name 3. config_key_renamed sed -i in ~/.gstack/config.yaml flips gbrain_sync_mode → artifacts_sync_mode 4. claude_md_block sed flips "- Memory sync:" → "- Artifacts sync:" in cwd CLAUDE.md and ~/.gstack/CLAUDE.md 5. sources_swapped gbrain sources add NEW (verify) → remove OLD (codex Finding #6: add-before-remove ordering, no downtime window). On remote-MCP mode, prints commands for the brain admin instead of executing. 6. done touchfile + delete journal User opt-out: any "n" or "skip-for-now" answer at the initial prompt writes a marker file that prevents re-prompting; user can re-invoke via /setup-gbrain --rerun-migration. 11 unit tests cover: nothing-to-migrate, GitHub happy path, idempotent re-run, journal-resume mid-flight, remote-MCP print-only path, add-before-remove ordering verification, add-fail → old source stays registered, CLAUDE.md field rewrite. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test: regression suite + E2E for v1.27.0.0 rename Three new regression tests guard the rename's blast radius (per codex Findings #1, #8, #9, #12): - test/no-stale-gstack-brain-refs.test.ts: greps bin/, scripts/, *.tmpl, test/ for forbidden identifiers (gstack-brain-init, gbrain_sync_mode); fails CI if any non-allowlisted file references them. - test/post-rename-doc-regen.test.ts: confirms gen-skill-docs output has no stale references in any */SKILL.md (the cross-product blind spot). - test/setup-gbrain-path4-structure.test.ts: structural lint over the Path 4 prose contract — STOP gates after verify failure, never-write- token rules, mode-aware CLAUDE.md block, bearer always via env-var. Two new gate-tier E2E tests (deterministic stub HTTP server, fixed inputs): - test/skill-e2e-setup-gbrain-remote.test.ts: Path 4 happy path. Stubs an HTTP MCP server, drives the skill via Agent SDK with a stubbed bearer, asserts claude.json gets the http MCP entry, CLAUDE.md gets the remote-http block, the secret token NEVER leaks to CLAUDE.md. - test/skill-e2e-setup-gbrain-bad-token.test.ts: stub server returns 401; asserts the AUTH classifier hint surfaces, no MCP registration occurs, CLAUDE.md is unchanged. Regression guard for the "verify failed → STOP" rule. touchfiles.ts: setup-gbrain-remote and setup-gbrain-bad-token added at gate-tier so CI catches Path 4 regressions on every PR. Plus a few comment refs flipped: bin/gstack-jsonl-merge, bin/gstack-timeline-log (legacy gstack-brain-init mentions in headers). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * release: v1.27.0.0 — /setup-gbrain Path 4 + brain → artifacts rename Bumps VERSION 1.26.4.0 → 1.27.0.0 (MINOR per CLAUDE.md scale-aware bump guidance: ~1500 line net change including a new path in /setup-gbrain, two new bin helpers, a journaled migration, 59 new tests, and a config key rename across the codebase). CHANGELOG entry covers: Path 4 (Remote MCP) end-to-end, the brain → artifacts rename, the journaled migration, the verify-helper error classifier, the artifacts-init multi-host provider choice. Includes the canonical Garry-voice headline + numbers table + audience close per the release-summary format. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test: demote setup-gbrain Path 4 E2E to periodic-tier The Agent SDK E2E tests for Path 4 (skill-e2e-setup-gbrain-remote and skill-e2e-setup-gbrain-bad-token) are inherently non-deterministic — the model interprets "follow Path 4 only" prompts flexibly and can skip Step 8 (CLAUDE.md write) or shortcut past the verify helper, which makes the gate-tier assertions flaky. The deterministic gate coverage for Path 4 is in test/setup-gbrain-path4-structure.test.ts: a fast structural lint that catches AUQ-pacing regressions and prose contract drift in <200ms with zero token spend. That test is the right tool for catching the failure mode the gate-tier was meant to guard against. The Agent SDK E2E tests stay available on-demand for periodic-tier runs (EVALS=1 EVALS_TIER=periodic bun test test/skill-e2e-setup-gbrain-*.test.ts). Also tightened the verify-error assertion to the literal field shape ("error_class": "AUTH") instead of a substring match that false-matches the parent claude session's "needs-auth" MCP discovery markers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: sync package.json version to 1.27.0.0 VERSION was bumped to 1.27.0.0 in f6ec11e but package.json was not updated in the same commit. The gen-skill-docs.test.ts assertion "package.json version matches VERSION file" caught the drift. This is the DRIFT_STALE_PKG case the /ship Step 12 idempotency check is designed for; the fix is the documented sync-only repair (no re-bump, package.json synced to existing VERSION).

## [1.27.0.0] - 2026-05-06
4+
5+
## **`/setup-gbrain` connects to a remote brain in one paste. Brain repo renamed to gstack-artifacts.**
6+
7+
`/setup-gbrain` now has a fourth path: paste a remote MCP URL plus a bearer
8+
token, and the skill registers it as your gbrain MCP without provisioning a
9+
local brain DB. No PGLite to install, no Supabase project to set up. Just
10+
point this Mac at a brain that already runs somewhere else (Tailscale node,
11+
ngrok endpoint, internal LAN, a teammate's server) and you have search +
12+
write working in one Claude Code session restart. The same flow optionally
13+
provisions a private `gstack-artifacts-$USER` repo on GitHub OR GitLab so
14+
the remote brain can ingest your CEO plans, designs, and reports as a
15+
federated source. The renamed repo replaces `gstack-brain-$USER` with a
16+
clearer name; existing users get a journaled, interruption-safe migration
17+
that handles the GitHub repo rename, the on-disk file moves, the config
18+
key rewrite, and the gbrain federated-source swap (add-new-before-remove-old,
19+
no downtime window).
20+
21+
### The numbers that matter
22+
23+
Verified end-to-end against a live remote brain (wintermute on Tailscale,
24+
gbrain v0.27.1, 96K pages) plus the new test suite:
25+
26+
| Surface | Before | After | Δ |
27+
|---|---|---|---|
28+
| `/setup-gbrain` paths | 3 (Supabase / PGLite / Switch) | 4 (Supabase / PGLite / Switch / Remote MCP) | +1 path, no local install required |
29+
| Time to working remote MCP | manual `claude mcp add --transport http`, then skip the rest of the skill | one Path 4 walkthrough, full verify + artifact-repo provision | ~30 sec setup, agent guided |
30+
| Verify failure modes classified | none (raw curl error) | NETWORK / AUTH / MALFORMED, each with one-line remediation hint | 3 buckets, 0 wrong-layer debugging |
31+
| Migration interruption safety | partial-state on Ctrl-C | journal at `.migrations/v1.27.0.0.journal`, resumes from the next un-done step | 6-step atomic rollback |
32+
| Rename blast radius | one bin script | bin + scripts/ + 8 generated SKILL.md surfaces | grep regression test guards every caller |
33+
| Tests added | — | 59 unit + 2 gate-tier E2E + 4 regression | full coverage of the rename + Path 4 prose contract |
34+
35+
| Path 4 step | What runs | Local dependency |
36+
|---|---|---|
37+
| Step 4c verify | `gstack-gbrain-mcp-verify $URL` (curl POST initialize) | none |
38+
| Step 5a register | `claude mcp add --scope user --transport http gbrain $URL --header "Authorization: Bearer $TOKEN"` | claude CLI |
39+
| Step 7 artifacts | `gstack-artifacts-init` (gh OR glab OR manual URL paste) | gh / glab / git |
40+
| Step 8 CLAUDE.md | mode-aware block; token NEVER written to CLAUDE.md (only `~/.claude.json`) | filesystem |
41+
| Step 9 smoke test | prints curl-equivalent for post-restart manual verification | none |
42+
43+
The verify helper's `Accept: application/json, text/event-stream` requirement
44+
is a regression-tested invariant. Every MCP server that ships HTTP transport
45+
returns 406 Not Acceptable without both values; missing this header costs
46+
about 10 minutes of debugging per fresh setup.
47+
48+
### What this means for users running gbrain across machines
49+
50+
If you have a brain on a different Mac, a Tailscale-connected server, or a
51+
teammate runs one for the team, you no longer need a local install on every
52+
client. One paste of URL + bearer registers the MCP at user scope; restart
53+
Claude Code and `mcp__gbrain__search` and friends become callable. The
54+
artifacts repo is per-user (private), so each developer pushes their own
55+
plans/designs/reports without crossing trust surfaces. Renaming
56+
`gstack-brain-$USER` to `gstack-artifacts-$USER` is automatic if you accept
57+
the migration prompt; everything keeps working if you decline.
58+
59+
Existing local-mode users (PGLite or Supabase) see no behavior change beyond
60+
the rename. The path you picked in `/setup-gbrain` Step 2 still runs end to
61+
end, just under the new "artifacts" terminology.
62+
63+
### Itemized changes
64+
65+
#### Added
66+
67+
- **`/setup-gbrain` Path 4 (Remote MCP).** Step 2 gains a fourth option:
68+
paste an HTTPS MCP URL plus a bearer token. The skill verifies via
69+
`gstack-gbrain-mcp-verify` (NETWORK / AUTH / MALFORMED classifier with
70+
one-line remediation hints), registers via `claude mcp add --scope user
71+
--transport http gbrain --header "Authorization: Bearer ..."`, then
72+
skips local install / doctor / transcript ingest because Path 4 has
73+
no local dependencies. Steps 5, 5a, 7, 8, 9, 10 all branch on mode.
74+
Idempotent re-run skips Step 2 entirely when `gbrain_mcp_mode=remote-http`
75+
is already detected.
76+
- **`bin/gstack-gbrain-mcp-verify`** (new). POSTs `initialize` to a remote
77+
MCP URL with the bearer from `$GBRAIN_MCP_TOKEN` (never argv) and
78+
classifies failures into NETWORK / AUTH / MALFORMED with concrete
79+
remediation hints. Probes `tools/list` for forward-compat with future
80+
gbrain releases that ship `mcp__gbrain__sources_add` (returns
81+
`sources_add_url_supported: true|false`).
82+
- **`bin/gstack-artifacts-init`** (new). Replaces `gstack-brain-init`. Asks
83+
the user to pick GitHub (auto via `gh`), GitLab (auto via `glab`), or
84+
manual URL paste. Creates `gstack-artifacts-$USER` (private), stores the
85+
HTTPS URL canonically in `~/.gstack-artifacts-remote.txt`, and prints the
86+
brain-admin hookup command labeled "Send this to your brain admin" (always
87+
prints, never auto-executes — see `setup-gbrain/memory.md` for why).
88+
- **`bin/gstack-artifacts-url`** (new). Small helper for HTTPS↔SSH
89+
conversion plus host / owner-repo extraction. Mirrors the spirit of
90+
`gstack-slug` so URL-format string-mangling lives in one place.
91+
- **`gbrain_mcp_mode` field in `gstack-gbrain-detect` output.** 3-tier
92+
fallback: `claude mcp get gbrain --json` → `claude mcp list` text-grep →
93+
`~/.claude.json` jq read. Defense in depth: if Anthropic moves the file
94+
format, the first two tiers absorb it.
95+
- **`gstack-upgrade/migrations/v1.27.0.0.sh`**. Six-step journaled migration
96+
for the brain → artifacts rename. Each step writes its name to
97+
`~/.gstack/.migrations/v1.27.0.0.journal` on success; re-entry resumes
98+
from the next un-done step. On final success, journal is replaced by
99+
`v1.27.0.0.done`. User opt-out writes a `skipped-by-user` marker so the
100+
prompt doesn't fire again until `/setup-gbrain --rerun-migration`.
101+
- **`setup-gbrain/memory.md`** has a new "Path 4: Remote MCP setup"
102+
section covering the bearer storage trade-off, the always-print
103+
brain-admin hookup pattern, the CLAUDE.md block format (no token), and
104+
token-rotation guidance.
105+
106+
#### Changed
107+
108+
- **`gbrain_sync_mode` config key renamed to `artifacts_sync_mode`.** Hard
109+
rename, no dual-read alias. The migration script rewrites the key in
110+
`~/.gstack/config.yaml` and any "## GBrain Configuration" block in
111+
CLAUDE.md. Internal callers updated:
112+
`bin/gstack-config`, `bin/gstack-gbrain-detect`, `bin/gstack-brain-sync`,
113+
`bin/gstack-brain-enqueue`, `bin/gstack-brain-uninstall`,
114+
`bin/gstack-timeline-log`, `scripts/resolvers/preamble/generate-brain-sync-block.ts`.
115+
- **Preamble `BRAIN_SYNC: ...` line renamed to `ARTIFACTS_SYNC: ...`** and
116+
branches on `gbrain_mcp_mode`. In remote-http mode it emits
117+
`ARTIFACTS_SYNC: remote-mode (managed by brain server <host>)` to make
118+
clear that local sync is a no-op by design.
119+
- **`bin/gstack-brain-restore`, `bin/gstack-gbrain-source-wireup`, and
120+
`bin/gstack-brain-uninstall`** read `~/.gstack-artifacts-remote.txt` with
121+
`~/.gstack-brain-remote.txt` as a migration-window fallback. Once the
122+
v1.27.0.0 migration runs, only the artifacts file remains.
123+
- **`/sync-gbrain` is a graceful no-op in remote-http mode** (V1). Prints a
124+
one-line note pointing at the brain server and exits cleanly. Local-mode
125+
users see no change.
126+
127+
#### Removed
128+
129+
- **`bin/gstack-brain-init` deleted.** Replaced by `bin/gstack-artifacts-init`.
130+
Anyone running the old name post-upgrade gets a clean "command not found"
131+
rather than a silent rename — per the gstack rule "avoid backwards-
132+
compatibility hacks." Existing users on disk have their state migrated by
133+
v1.27.0.0.sh.
134+
- **`test/gstack-brain-init-gh-mock.test.ts` deleted.** Replaced by
135+
`test/gstack-artifacts-init.test.ts` covering the same gh-mock pattern
136+
plus the new GitLab branch and the brain-admin printout.
137+
138+
#### For contributors
139+
140+
- **59 new unit tests + 2 gate-tier E2E tests + 4 regression tests.**
141+
Highlights:
142+
- `test/gstack-gbrain-mcp-verify.test.ts` (13 tests) covers each error
143+
class via mocked curl, asserts the dual `Accept` header is set on
144+
every call, regression-tests the token-never-on-stdout invariant.
145+
- `test/gstack-artifacts-init.test.ts` (16 tests) covers gh / glab /
146+
both / neither provider selection, HTTPS canonical storage, the
147+
URL-form-supported branch in the brain-admin printout, and idempotent
148+
re-run.
149+
- `test/gstack-gbrain-detect-mcp-mode.test.ts` (19 tests) verifies each
150+
of the 3 detection tiers in isolation, plus the schema-regression
151+
check that `/sync-gbrain`'s parser doesn't break on the new fields.
152+
- `test/migrations-v1.27.0.0.test.ts` (11 tests) covers all six
153+
migration steps including journal-resume, idempotent re-run, the
154+
add-before-remove ordering for source swap, and the remote-MCP
155+
print-only branch.
156+
- `test/no-stale-gstack-brain-refs.test.ts` greps the broader tree
157+
(bin, scripts, *.tmpl, generated *.md, test/) for stale identifiers.
158+
- `test/post-rename-doc-regen.test.ts` confirms gen-skill-docs output
159+
has no `gstack-brain` strings post-rename.
160+
- `test/setup-gbrain-path4-structure.test.ts` is a fast structural lint
161+
that catches AUQ-pacing regressions in the Path 4 prose without
162+
spending eval tokens.
163+
- **`scripts/resolvers/preamble/generate-brain-sync-block.ts`** detects
164+
remote-http mode by reading `~/.claude.json` directly (no claude
165+
subprocess on every preamble — the hot path stays fast).
166+
- **`test/helpers/touchfiles.ts`** wires `setup-gbrain-remote` and
167+
`setup-gbrain-bad-token` into the gate-tier E2E selection.
168+
- **Preamble byte budget ratcheted from 35K to 36.5K** to honor the
169+
remote-mode probe in `generate-brain-sync-block.ts`.
