feat(setup-gbrain): carve the branch-exclusive install paths into sections

Brain-init (Paths 1/2/3/4 bodies), engine remediation, transcript gate, and
CLAUDE.md persist load on demand — at most one install route ever runs.
Skeleton 75.3KB -> 57.0KB; the Step 1 detect and Step 2 path dispatch stay
always-loaded. New buildSetupGbrainFixture helper gives the periodic E2Es
extract-don't-copy fixtures with a non-empty guard; the voyage-code-3 gate
counts scan the tmpl union (the third init site lives in engine-remediation).

| initializing the brain in Step 4 — run ONLY the procedure for the path picked in Step 2 (Paths 1/2a/2b/3/4 or Switch; also holds the PAT scope disclosure that `--cleanup-orphans` re-uses) | `sections/brain-init.md` |
| running the Step 7.5 transcript & memory ingest gate on Paths 1, 2a, 2b, or 3 (Path 4 skips this section entirely — see the skeleton's skip note) | `sections/transcript-gate.md` |

## Step 4: Initialize the brain
Path-specific.
Path-specific. The init procedure for the path picked in Step 2 — Paths 1, 2a,
2b, 3, 4 (4a-4e), and the Switch migration flow — lives in the brain-init
section. Run ONLY the sub-section for the picked path.
### Path 1 (Supabase, existing URL)
Source the secret-read helper, collect URL with `read -s` + redacted preview:
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env GBRAIN_POOLER_URL "Paste Session Pooler URL: " \
--echo-redacted 's#://[^@]*@#://***@#'
```
Then validate structurally:
```bash
printf '%s' "$GBRAIN_POOLER_URL" | ~/.claude/skills/gstack/bin/gstack-gbrain-supabase-verify -
```
If the verify exit code is 3 (direct-connection URL), the verifier's own
message explains the fix; surface it and re-prompt for a Session Pooler URL.
On success, hand off to gbrain via env var (D10, never argv):
```bash
GBRAIN_DATABASE_URL="$GBRAIN_POOLER_URL" gbrain init --non-interactive --json
```
Then `unset GBRAIN_POOLER_URL GBRAIN_DATABASE_URL` immediately. The URL is
now persisted in `~/.gbrain/config.json` at mode 0600 by gbrain itself.
### Path 2a (Supabase, auto-provision — D7)
Show the D11 PAT scope disclosure verbatim BEFORE collecting the token:
> *This Supabase Personal Access Token grants full read/write/delete access
> to every project in your Supabase account, not just the `gbrain` one we're
> about to create. Supabase doesn't currently support scoped tokens. We use
> this PAT only to: create one project, poll it until healthy, read the
> Session Pooler URL — then discard it from process memory. The token
> remains valid on Supabase's side until you manually revoke it at
> https://supabase.com/dashboard/account/tokens — we recommend revoking
> immediately after setup completes.*
Then:
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env SUPABASE_ACCESS_TOKEN "Paste PAT: "
```
Ask the D17 tier prompt via AskUserQuestion: "Which Supabase tier?" Present
Free (2-project limit, pauses after 7d inactivity) vs Pro ($25/mo, no
pauses, recommended for real use). Explain that tier is **org-level** (per
the Management API contract) — user picks their org based on its current
tier. Pro may require them to upgrade the org first at supabase.com.
List orgs, pick one (AskUserQuestion if multiple):
```bash
orgs=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision list-orgs --json)
```
If the `.orgs` array is empty, surface: "Your Supabase account has no
organizations. Create one at https://supabase.com/dashboard, then re-run
`/setup-gbrain`." STOP.
Ask the user for a region (default `us-east-1`; valid values are the 18
enum values in the Supabase Management API — list a few common ones, let
them pick "Other" for a full list).
Generate the DB password (never shown to the user):
```bash
export DB_PASS=$(openssl rand -base64 24)
```
Set up a SIGINT trap (D12 basic recovery):
```bash
trap 'echo ""; echo "gstack-gbrain: interrupted. In-flight ref: $INFLIGHT_REF"; \
echo "Resume: /setup-gbrain --resume-provision $INFLIGHT_REF"; \
echo "Delete: https://supabase.com/dashboard/project/$INFLIGHT_REF"; \
unset SUPABASE_ACCESS_TOKEN DB_PASS; exit 130' INT TERM
```
Create + wait + fetch:
```bash
result=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \
create gbrain "$REGION" "$ORG_SLUG" --json)
INFLIGHT_REF=$(echo "$result" | jq -r .ref)
~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision wait "$INFLIGHT_REF" --json
pooler=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \
pooler-url "$INFLIGHT_REF" --json)
GBRAIN_DATABASE_URL=$(echo "$pooler" | jq -r .pooler_url)
export GBRAIN_DATABASE_URL
gbrain init --non-interactive --json
unset SUPABASE_ACCESS_TOKEN DB_PASS GBRAIN_DATABASE_URL INFLIGHT_REF
trap - INT TERM
```
After success, emit the PAT revocation reminder:
> "Setup complete. Revoke the PAT you pasted at
> https://supabase.com/dashboard/account/tokens — we've already discarded
> it from memory and don't need it again. The gbrain project will continue
> working because it uses its own embedded database password."
### Path 2b (Supabase, manual)
Walk the user through the supabase.com steps:
1. Login at https://supabase.com/dashboard
2. Click "New Project," name it `gbrain`, pick a region, copy the generated
database password (you'll need it for paste-back? no — it's embedded in
the pooler URL we collect next)
3. Wait ~2 min for the project to initialize
4. Settings → Database → Connection Pooler → Session → copy the URL (port
6543)
Then follow the same secret-read + verify + init flow as Path 1.
### Path 3 (PGLite local)
```bash
# gstack default: voyage-code-3 (1024d) when VOYAGE_API_KEY is set — code
# retrieval beats general-purpose embeddings on real code queries (validated
# A/B). Without the key, gbrain auto-selects (OpenAI 1536d when available).
# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
if [ -n "${VOYAGE_API_KEY:-}" ]; then
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
fi
gbrain init --pglite --json "$@"
```
Done. No network, no secrets (beyond Voyage embedding API calls during sync, if
`VOYAGE_API_KEY` is set — ~$0.18 per 1M tokens, pennies per repo).
### Path 4 (Remote gbrain MCP — HTTP transport with bearer token)
For users whose brain runs on another machine (Tailscale, ngrok, internal
LAN, or a teammate's server). No local gbrain CLI install, no local DB.
This skill registers the remote MCP and stops; ingestion + indexing happens
on the brain host.
**4a. Collect MCP URL.** Prompt the user:
```
Paste your gbrain MCP URL (e.g. https://wintermute.tail554574.ts.net:3131/mcp):
```
Read with plain `read -r` (no secret hygiene needed — the URL alone isn't
a credential). Validate it starts with `https://` (require TLS for any
non-loopback host); refuse `http://` for non-localhost.
**4b. Collect bearer token via the secret-read helper (D10, never argv).**
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env GBRAIN_MCP_TOKEN "Paste bearer token: " \
--echo-redacted 's/.\{6\}$/***REDACTED***/'
```
**4c. Verify via gstack-gbrain-mcp-verify.** Run the helper; capture the
classified JSON output:
```bash
verify_json=$(GBRAIN_MCP_TOKEN="$GBRAIN_MCP_TOKEN" \
~/.claude/skills/gstack/bin/gstack-gbrain-mcp-verify "$MCP_URL")
status=$(echo "$verify_json" | jq -r .status)
```
If `status != "success"`, the helper has already classified the failure
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
Surface the hint above the raw error from `error_text` and **STOP** with
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
on a failed verify — partial registration would leave the user with a
half-broken state.
Capture two values from the verify output for downstream steps:
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
Step 7 to control which form of the brain-admin hookup command is printed.
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
> D# — Want symbol-aware code search on this machine?
> Project/branch/task: <one-sentence grounding using detected slug + branch>
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
> from your remote brain. Transcripts and artifacts continue routing through
> the artifacts repo to the remote brain — local PGLite stays code-only.
> Stakes: without it, semantic code search in this repo's worktrees falls
> back to Grep.
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
> A) Yes, set up local PGLite for code (recommended)
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
> ✅ Independent engine — won't disturb remote brain or share transcripts
> B) No, remote MCP only
> ✅ Zero local state — only `~/.claude.json` MCP registration
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
> Net: A = full split-engine; B = remote-only.
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
```bash
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
# existing ~/.gbrain/config.json first (rollback if init fails).
if [ -f "$HOME/.gbrain/config.json" ]; then
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
mv "$HOME/.gbrain/config.json" "$BACKUP"
fi
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
# text-embedding-3-large on this codebase's symbol queries. Falls back to
# gbrain's auto-selected provider when the key isn't present.
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
if [ -n "${VOYAGE_API_KEY:-}" ]; then
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
fi
if ! gbrain init --pglite --json "$@"; then
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
fi
```
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
today; the local PGLite is independent of MCP registration (Claude Code talks
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
for code-def/refs/callers).
**If B (No)**: skip the install + init. The local engine stays absent.
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
since memory-stage routes through the artifacts pipeline in remote-http mode
per plan D11.
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's
`claude mcp add --header` consumes it; then `unset GBRAIN_MCP_TOKEN`
immediately. Token security trade-off documented in
`setup-gbrain/memory.md`: brief argv exposure during `claude mcp add`,
resting state in `~/.claude.json` mode 0600.
### Switch (from detect's existing-engine state)
```bash
# Going PGLite → Supabase, collect URL first (Path 1 flow), then:
timeout 180s gbrain migrate --to supabase --url "$URL" --json
# Going Supabase → PGLite:
timeout 180s gbrain migrate --to pglite --json
```
If `timeout` returns 124 (exit code for timeout): surface D9 message
("Migration didn't complete in 3 minutes — another gstack session may be
holding a lock on the source brain. Close other workspaces and re-run
`/setup-gbrain --switch`. Your original brain is untouched."). STOP.

## Step 8: Persist `## GBrain Configuration` in CLAUDE.md
Find-and-replace (or append) the section. Block format depends on mode:
CLAUDE.md is the audit trail: after a successful setup, persist the
configuration block. The exact block formats (remote-http vs local-stdio) and
the post-Step-9 Search Guidance write live in the claude-md-persist section.
### Path 4 (Remote MCP)
```markdown
## GBrain Configuration (configured by /setup-gbrain)
- Mode: remote-http
- MCP URL: {MCP_URL}
- Server version: gbrain v{SERVER_VERSION} (from Step 4c verify)
- Setup date: {today}
- MCP registered: yes (user scope)
- Token: stored in ~/.claude.json (do not commit; never written to CLAUDE.md)
- Artifacts repo: {gstack_artifacts_remote URL or "none"}
- Artifacts sync: {off|artifacts-only|full}
- Current repo policy: {read-write|read-only|deny|unset}
```
The bearer token is **never** written to CLAUDE.md (CLAUDE.md is checked
in to git in many projects). It lives only in `~/.claude.json` where
`claude mcp add` placed it.
### Paths 1, 2a, 2b, 3 (Local stdio)
```markdown
## GBrain Configuration (configured by /setup-gbrain)
- Mode: local-stdio
- Engine: {pglite|postgres}
- Config file: ~/.gbrain/config.json (mode 0600)
- Setup date: {today}
- MCP registered: {yes/no}
- Artifacts sync: {off|artifacts-only|full}
- Current repo policy: {read-write|read-only|deny|unset}
```
**After Step 9 (smoke test) passes, also write the `## GBrain Search Guidance`
block** so the coding agent learns when to prefer `gbrain` over Grep. This
block is gated on the smoke test passing — write the Configuration block
first (so the user knows what state they're in even if the smoke test fails),
then return here after Step 9 and write the guidance block only if smoke
test succeeded.
When Step 9 passes, find-and-replace (or append) this block. Use HTML-comment
delimiters so removal regex is unambiguous and never eats user content. The
block content is machine-AGNOSTIC — no engine type, no page counts, no
last-sync time. Machine state stays in the Configuration block above.
```markdown
## GBrain Search Guidance (configured by /sync-gbrain)
<!-- gstack-gbrain-search-guidance:start -->
GBrain is set up and synced on this machine. The agent should prefer gbrain
over Grep when the question is semantic or when you don't know the exact
identifier yet. Two indexed corpora available via the `gbrain` CLI:
- This repo's code (registered as `gstack-code-<repo>` source).
- `~/.gstack/` curated memory (registered as `gstack-brain-<user>` source via
the existing federation pipeline).
Prefer gbrain when:
- "Where is X handled?" / semantic intent, no exact string yet:
`gbrain search "<terms>"` or `gbrain query "<question>"`
- "Where is symbol Y defined?" / symbol-based code questions:
`gbrain code-def <symbol>` or `gbrain code-refs <symbol>`
- "What calls Y?" / "What does Y depend on?":
`gbrain code-callers <symbol>` / `gbrain code-callees <symbol>`
- "What did we decide last time?" / past plans, retros, learnings:
`gbrain search "<terms>" --source gstack-brain-<user>`
Grep is still right for known exact strings, regex, multiline patterns, and
file globs. The brain auto-syncs incrementally on every gstack skill start.
Run `/sync-gbrain` to force-refresh, `/sync-gbrain --full` for full reindex.
<!-- gstack-gbrain-search-guidance:end -->

2b, 3, 4 (4a-4e), and the Switch migration flow — lives in the brain-init
section. Run ONLY the sub-section for the picked path.
### Path 1 (Supabase, existing URL)
Source the secret-read helper, collect URL with `read -s` + redacted preview:
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env GBRAIN_POOLER_URL "Paste Session Pooler URL: " \
--echo-redacted 's#://[^@]*@#://***@#'

Then validate structurally:
```bash
printf '%s' "$GBRAIN_POOLER_URL" | ~/.claude/skills/gstack/bin/gstack-gbrain-supabase-verify -
```
If the verify exit code is 3 (direct-connection URL), the verifier's own
message explains the fix; surface it and re-prompt for a Session Pooler URL.
On success, hand off to gbrain via env var (D10, never argv):
```bash
GBRAIN_DATABASE_URL="$GBRAIN_POOLER_URL" gbrain init --non-interactive --json
```
Then `unset GBRAIN_POOLER_URL GBRAIN_DATABASE_URL` immediately. The URL is
now persisted in `~/.gbrain/config.json` at mode 0600 by gbrain itself.
### Path 2a (Supabase, auto-provision — D7)
Show the D11 PAT scope disclosure verbatim BEFORE collecting the token:
> *This Supabase Personal Access Token grants full read/write/delete access
> to every project in your Supabase account, not just the `gbrain` one we're
> about to create. Supabase doesn't currently support scoped tokens. We use

> Session Pooler URL — then discard it from process memory. The token
> remains valid on Supabase's side until you manually revoke it at
> https://supabase.com/dashboard/account/tokens — we recommend revoking
> immediately after setup completes.*
Then:
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env SUPABASE_ACCESS_TOKEN "Paste PAT: "
```
Ask the D17 tier prompt via AskUserQuestion: "Which Supabase tier?" Present
Free (2-project limit, pauses after 7d inactivity) vs Pro ($25/mo, no
pauses, recommended for real use). Explain that tier is **org-level** (per
the Management API contract) — user picks their org based on its current
tier. Pro may require them to upgrade the org first at supabase.com.
List orgs, pick one (AskUserQuestion if multiple):
```bash
orgs=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision list-orgs --json)
```
If the `.orgs` array is empty, surface: "Your Supabase account has no
organizations. Create one at https://supabase.com/dashboard, then re-run
`/setup-gbrain`." STOP.
Ask the user for a region (default `us-east-1`; valid values are the 18
enum values in the Supabase Management API — list a few common ones, let
them pick "Other" for a full list).
Generate the DB password (never shown to the user):
```bash
export DB_PASS=$(openssl rand -base64 24)
```
Set up a SIGINT trap (D12 basic recovery):
```bash
trap 'echo ""; echo "gstack-gbrain: interrupted. In-flight ref: $INFLIGHT_REF"; \
echo "Resume: /setup-gbrain --resume-provision $INFLIGHT_REF"; \
echo "Delete: https://supabase.com/dashboard/project/$INFLIGHT_REF"; \
unset SUPABASE_ACCESS_TOKEN DB_PASS; exit 130' INT TERM
```
Create + wait + fetch:
```bash
result=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \
create gbrain "$REGION" "$ORG_SLUG" --json)
INFLIGHT_REF=$(echo "$result" | jq -r .ref)

export GBRAIN_DATABASE_URL
gbrain init --non-interactive --json
unset SUPABASE_ACCESS_TOKEN DB_PASS GBRAIN_DATABASE_URL INFLIGHT_REF
trap - INT TERM
```
After success, emit the PAT revocation reminder:
> "Setup complete. Revoke the PAT you pasted at
> https://supabase.com/dashboard/account/tokens — we've already discarded
> it from memory and don't need it again. The gbrain project will continue
> working because it uses its own embedded database password."
### Path 2b (Supabase, manual)
Walk the user through the supabase.com steps:
1. Login at https://supabase.com/dashboard
2. Click "New Project," name it `gbrain`, pick a region, copy the generated
database password (you'll need it for paste-back? no — it's embedded in
the pooler URL we collect next)
3. Wait ~2 min for the project to initialize
4. Settings → Database → Connection Pooler → Session → copy the URL (port
6543)
Then follow the same secret-read + verify + init flow as Path 1.
### Path 3 (PGLite local)
```bash
# gstack default: voyage-code-3 (1024d) when VOYAGE_API_KEY is set — code
# retrieval beats general-purpose embeddings on real code queries (validated
# A/B). Without the key, gbrain auto-selects (OpenAI 1536d when available).
# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
if [ -n "${VOYAGE_API_KEY:-}" ]; then
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
fi
gbrain init --pglite --json "$@"
```
Done. No network, no secrets (beyond Voyage embedding API calls during sync, if
`VOYAGE_API_KEY` is set — ~$0.18 per 1M tokens, pennies per repo).
### Path 4 (Remote gbrain MCP — HTTP transport with bearer token)
For users whose brain runs on another machine (Tailscale, ngrok, internal
LAN, or a teammate's server). No local gbrain CLI install, no local DB.
This skill registers the remote MCP and stops; ingestion + indexing happens
on the brain host.
**4a. Collect MCP URL.** Prompt the user:
```
Paste your gbrain MCP URL (e.g. https://wintermute.tail554574.ts.net:3131/mcp):
```
Read with plain `read -r` (no secret hygiene needed — the URL alone isn't
a credential). Validate it starts with `https://` (require TLS for any
non-loopback host); refuse `http://` for non-localhost.
**4b. Collect bearer token via the secret-read helper (D10, never argv).**
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env GBRAIN_MCP_TOKEN "Paste bearer token: " \
--echo-redacted 's/.\{6\}$/***REDACTED***/'
```
**4c. Verify via gstack-gbrain-mcp-verify.** Run the helper; capture the
classified JSON output:
```bash
verify_json=$(GBRAIN_MCP_TOKEN="$GBRAIN_MCP_TOKEN" \
~/.claude/skills/gstack/bin/gstack-gbrain-mcp-verify "$MCP_URL")
status=$(echo "$verify_json" | jq -r .status)
```
If `status != "success"`, the helper has already classified the failure
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
Surface the hint above the raw error from `error_text` and **STOP** with
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
on a failed verify — partial registration would leave the user with a
half-broken state.
Capture two values from the verify output for downstream steps:
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
Step 7 to control which form of the brain-admin hookup command is printed.
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
> D# — Want symbol-aware code search on this machine?
> Project/branch/task: <one-sentence grounding using detected slug + branch>
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
> from your remote brain. Transcripts and artifacts continue routing through
> the artifacts repo to the remote brain — local PGLite stays code-only.
> Stakes: without it, semantic code search in this repo's worktrees falls
> back to Grep.
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
> A) Yes, set up local PGLite for code (recommended)
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
> ✅ Independent engine — won't disturb remote brain or share transcripts
> B) No, remote MCP only
> ✅ Zero local state — only `~/.claude.json` MCP registration
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
> Net: A = full split-engine; B = remote-only.
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
```bash
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
# existing ~/.gbrain/config.json first (rollback if init fails).
if [ -f "$HOME/.gbrain/config.json" ]; then
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
mv "$HOME/.gbrain/config.json" "$BACKUP"
fi
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
# text-embedding-3-large on this codebase's symbol queries. Falls back to
# gbrain's auto-selected provider when the key isn't present.
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
if [ -n "${VOYAGE_API_KEY:-}" ]; then
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
fi
if ! gbrain init --pglite --json "$@"; then
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
fi
```
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
today; the local PGLite is independent of MCP registration (Claude Code talks
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
for code-def/refs/callers).
**If B (No)**: skip the install + init. The local engine stays absent.
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
since memory-stage routes through the artifacts pipeline in remote-http mode
per plan D11.
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's
`claude mcp add --header` consumes it; then `unset GBRAIN_MCP_TOKEN`
immediately. Token security trade-off documented in
`setup-gbrain/memory.md`: brief argv exposure during `claude mcp add`,
resting state in `~/.claude.json` mode 0600.
### Switch (from detect's existing-engine state)
```bash
# Going PGLite → Supabase, collect URL first (Path 1 flow), then:
timeout 180s gbrain migrate --to supabase --url "$URL" --json
# Going Supabase → PGLite:
timeout 180s gbrain migrate --to pglite --json
```
If `timeout` returns 124 (exit code for timeout): surface D9 message
("Migration didn't complete in 3 minutes — another gstack session may be
holding a lock on the source brain. Close other workspaces and re-run
`/setup-gbrain --switch`. Your original brain is untouched."). STOP.

## Step 8: Persist `## GBrain Configuration` in CLAUDE.md
Find-and-replace (or append) the section. Block format depends on mode:
CLAUDE.md is the audit trail: after a successful setup, persist the
configuration block. The exact block formats (remote-http vs local-stdio) and
the post-Step-9 Search Guidance write live in the claude-md-persist section.
### Path 4 (Remote MCP)
```markdown
## GBrain Configuration (configured by /setup-gbrain)
- Mode: remote-http
- MCP URL: {MCP_URL}
- Server version: gbrain v{SERVER_VERSION} (from Step 4c verify)
- Setup date: {today}
- MCP registered: yes (user scope)
- Token: stored in ~/.claude.json (do not commit; never written to CLAUDE.md)
- Artifacts repo: {gstack_artifacts_remote URL or "none"}
- Artifacts sync: {off|artifacts-only|full}
- Current repo policy: {read-write|read-only|deny|unset}
```
The bearer token is **never** written to CLAUDE.md (CLAUDE.md is checked
in to git in many projects). It lives only in `~/.claude.json` where
`claude mcp add` placed it.
### Paths 1, 2a, 2b, 3 (Local stdio)
```markdown
## GBrain Configuration (configured by /setup-gbrain)
- Mode: local-stdio
- Engine: {pglite|postgres}
- Config file: ~/.gbrain/config.json (mode 0600)
- Setup date: {today}
- MCP registered: {yes/no}
- Artifacts sync: {off|artifacts-only|full}
- Current repo policy: {read-write|read-only|deny|unset}
```
**After Step 9 (smoke test) passes, also write the `## GBrain Search Guidance`
block** so the coding agent learns when to prefer `gbrain` over Grep. This
block is gated on the smoke test passing — write the Configuration block
first (so the user knows what state they're in even if the smoke test fails),
then return here after Step 9 and write the guidance block only if smoke
test succeeded.
When Step 9 passes, find-and-replace (or append) this block. Use HTML-comment
delimiters so removal regex is unambiguous and never eats user content. The
block content is machine-AGNOSTIC — no engine type, no page counts, no
last-sync time. Machine state stays in the Configuration block above.
```markdown
## GBrain Search Guidance (configured by /sync-gbrain)
<!-- gstack-gbrain-search-guidance:start -->
GBrain is set up and synced on this machine. The agent should prefer gbrain
over Grep when the question is semantic or when you don't know the exact
identifier yet. Two indexed corpora available via the `gbrain` CLI:
- This repo's code (registered as `gstack-code-<repo>` source).
- `~/.gstack/` curated memory (registered as `gstack-brain-<user>` source via
the existing federation pipeline).
Prefer gbrain when:
- "Where is X handled?" / semantic intent, no exact string yet:
`gbrain search "<terms>"` or `gbrain query "<question>"`
- "Where is symbol Y defined?" / symbol-based code questions:
`gbrain code-def <symbol>` or `gbrain code-refs <symbol>`
- "What calls Y?" / "What does Y depend on?":
`gbrain code-callers <symbol>` / `gbrain code-callees <symbol>`
- "What did we decide last time?" / past plans, retros, learnings:
`gbrain search "<terms>" --source gstack-brain-<user>`
Grep is still right for known exact strings, regex, multiline patterns, and
file globs. The brain auto-syncs incrementally on every gstack skill start.
Run `/sync-gbrain` to force-refresh, `/sync-gbrain --full` for full reindex.
<!-- gstack-gbrain-search-guidance:end -->
```
If Step 9 smoke test fails, skip the guidance block write entirely. The user's
next `/sync-gbrain` run will re-evaluate capability and write the block when
the round-trip works.

### Path 2a (Supabase, auto-provision — D7)
Show the D11 PAT scope disclosure verbatim BEFORE collecting the token:
> *This Supabase Personal Access Token grants full read/write/delete access
> to every project in your Supabase account, not just the `gbrain` one we're
> about to create. Supabase doesn't currently support scoped tokens. We use

> Session Pooler URL — then discard it from process memory. The token
> remains valid on Supabase's side until you manually revoke it at
> https://supabase.com/dashboard/account/tokens — we recommend revoking
> immediately after setup completes.*
Then:
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env SUPABASE_ACCESS_TOKEN "Paste PAT: "
```
Ask the D17 tier prompt via AskUserQuestion: "Which Supabase tier?" Present
Free (2-project limit, pauses after 7d inactivity) vs Pro ($25/mo, no
pauses, recommended for real use). Explain that tier is **org-level** (per
the Management API contract) — user picks their org based on its current
tier. Pro may require them to upgrade the org first at supabase.com.
List orgs, pick one (AskUserQuestion if multiple):
```bash
orgs=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision list-orgs --json)
```
If the `.orgs` array is empty, surface: "Your Supabase account has no
organizations. Create one at https://supabase.com/dashboard, then re-run
`/setup-gbrain`." STOP.
Ask the user for a region (default `us-east-1`; valid values are the 18
enum values in the Supabase Management API — list a few common ones, let
them pick "Other" for a full list).
Generate the DB password (never shown to the user):
```bash
export DB_PASS=$(openssl rand -base64 24)
```
Set up a SIGINT trap (D12 basic recovery):
```bash
trap 'echo ""; echo "gstack-gbrain: interrupted. In-flight ref: $INFLIGHT_REF"; \
echo "Resume: /setup-gbrain --resume-provision $INFLIGHT_REF"; \
echo "Delete: https://supabase.com/dashboard/project/$INFLIGHT_REF"; \
unset SUPABASE_ACCESS_TOKEN DB_PASS; exit 130' INT TERM
```
Create + wait + fetch:
```bash
result=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \
create gbrain "$REGION" "$ORG_SLUG" --json)
INFLIGHT_REF=$(echo "$result" | jq -r .ref)
~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision wait "$INFLIGHT_REF" --json
pooler=$(~/.claude/skills/gstack/bin/gstack-gbrain-supabase-provision \

GBRAIN_DATABASE_URL=$(echo "$pooler" | jq -r .pooler_url)
export GBRAIN_DATABASE_URL
gbrain init --non-interactive --json
unset SUPABASE_ACCESS_TOKEN DB_PASS GBRAIN_DATABASE_URL INFLIGHT_REF
trap - INT TERM
```
After success, emit the PAT revocation reminder:
> "Setup complete. Revoke the PAT you pasted at
> https://supabase.com/dashboard/account/tokens — we've already discarded
> it from memory and don't need it again. The gbrain project will continue
> working because it uses its own embedded database password."
### Path 2b (Supabase, manual)
Walk the user through the supabase.com steps:
1. Login at https://supabase.com/dashboard
2. Click "New Project," name it `gbrain`, pick a region, copy the generated
database password (you'll need it for paste-back? no — it's embedded in
the pooler URL we collect next)
3. Wait ~2 min for the project to initialize
4. Settings → Database → Connection Pooler → Session → copy the URL (port
6543)
Then follow the same secret-read + verify + init flow as Path 1.
### Path 3 (PGLite local)
```bash
# gstack default: voyage-code-3 (1024d) when VOYAGE_API_KEY is set — code
# retrieval beats general-purpose embeddings on real code queries (validated
# A/B). Without the key, gbrain auto-selects (OpenAI 1536d when available).
# Never select gbrain's legacy zeroentropyai recipe for a new brain: the hosted
# API sunsets September 4, 2026 (#2365); the wireup helper warns existing installs.
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
if [ -n "${VOYAGE_API_KEY:-}" ]; then
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
fi
gbrain init --pglite --json "$@"
```
Done. No network, no secrets (beyond Voyage embedding API calls during sync, if
`VOYAGE_API_KEY` is set — ~$0.18 per 1M tokens, pennies per repo).
### Path 4 (Remote gbrain MCP — HTTP transport with bearer token)
For users whose brain runs on another machine (Tailscale, ngrok, internal
LAN, or a teammate's server). No local gbrain CLI install, no local DB.
This skill registers the remote MCP and stops; ingestion + indexing happens
on the brain host.
**4a. Collect MCP URL.** Prompt the user:
```
Paste your gbrain MCP URL (e.g. https://wintermute.tail554574.ts.net:3131/mcp):
```
Read with plain `read -r` (no secret hygiene needed — the URL alone isn't
a credential). Validate it starts with `https://` (require TLS for any
non-loopback host); refuse `http://` for non-localhost.
**4b. Collect bearer token via the secret-read helper (D10, never argv).**
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env GBRAIN_MCP_TOKEN "Paste bearer token: " \
--echo-redacted 's/.\{6\}$/***REDACTED***/'
```
**4c. Verify via gstack-gbrain-mcp-verify.** Run the helper; capture the
classified JSON output:
```bash
verify_json=$(GBRAIN_MCP_TOKEN="$GBRAIN_MCP_TOKEN" \
~/.claude/skills/gstack/bin/gstack-gbrain-mcp-verify "$MCP_URL")
status=$(echo "$verify_json" | jq -r .status)
```
If `status != "success"`, the helper has already classified the failure
into NETWORK / AUTH / MALFORMED and emitted a one-line remediation hint.
Surface the hint above the raw error from `error_text` and **STOP** with
a clear "fix and re-run /setup-gbrain" message. Do NOT continue to Step 5a
on a failed verify — partial registration would leave the user with a
half-broken state.
Capture two values from the verify output for downstream steps:
- `SERVER_VERSION` (e.g., `0.27.1`) — written to the CLAUDE.md block in Step 8.
- `URL_FORM_SUPPORTED` (`true|false`) — passed to `gstack-artifacts-init` in
Step 7 to control which form of the brain-admin hookup command is printed.
**4d. (Path 4) Offer local PGLite for code search.** Per plan D10/D11, ask:
> D# — Want symbol-aware code search on this machine?
> Project/branch/task: <one-sentence grounding using detected slug + branch>
> ELI10: The remote brain at `<MCP_URL>` is great for cross-machine knowledge,
> but symbol queries like `gbrain code-def` / `code-refs` / `code-callers` need
> a local index of THIS machine's code. We can spin up a tiny isolated PGLite
> database (~30 seconds, no accounts, ~120 MB disk) just for code, separate
> from your remote brain. Transcripts and artifacts continue routing through
> the artifacts repo to the remote brain — local PGLite stays code-only.
> Stakes: without it, semantic code search in this repo's worktrees falls
> back to Grep.
> Recommendation: A — 30 seconds, no ongoing cost, unlocks the symbol tools.
> Completeness: A=10/10 (full split-engine), B=7/10 (remote-only).
> A) Yes, set up local PGLite for code (recommended)
> ✅ Unlocks `gbrain code-def`, `code-refs`, `code-callers` per worktree
> ✅ Independent engine — won't disturb remote brain or share transcripts
> B) No, remote MCP only
> ✅ Zero local state — only `~/.claude.json` MCP registration
> ❌ Symbol code queries fall back to Grep in this repo's worktrees
> Net: A = full split-engine; B = remote-only.
**If A (Yes)**: install + init local PGLite with rollback-safe semantics (D7):
```bash
~/.claude/skills/gstack/bin/gstack-gbrain-install || exit $?
# At this point the local gbrain CLI is on PATH. Init PGLite, but back up any
# existing ~/.gbrain/config.json first (rollback if init fails).
if [ -f "$HOME/.gbrain/config.json" ]; then
BACKUP="$HOME/.gbrain/config.json.gstack-bak-$(date +%s)"
mv "$HOME/.gbrain/config.json" "$BACKUP"
fi
# gstack default for local code-search PGLite: voyage-code-3 (1024d) when
# VOYAGE_API_KEY is set. It wins the A/B over voyage-4-large and OpenAI
# text-embedding-3-large on this codebase's symbol queries. Falls back to
# gbrain's auto-selected provider when the key isn't present.
set -- # flags ride the positional params — unquoted $VAR breaks under zsh word-splitting (#1798)
if [ -n "${VOYAGE_API_KEY:-}" ]; then
set -- --embedding-model voyage:voyage-code-3 --embedding-dimensions 1024
fi
if ! gbrain init --pglite --json "$@"; then
if [ -n "${BACKUP:-}" ] && [ -f "$BACKUP" ]; then mv "$BACKUP" "$HOME/.gbrain/config.json"; fi
echo "gbrain init failed. Existing config (if any) was restored. PGLite at ~/.gbrain/pglite/ may be in a partial state — \`rm -rf ~/.gbrain/pglite\` to reset." >&2
echo "Continuing setup without local code search; you can re-run /setup-gbrain to retry." >&2
fi
```
Then continue to Step 5a. The remote-http MCP registration in 5a runs as
today; the local PGLite is independent of MCP registration (Claude Code talks
to the remote brain via MCP for queries; `gbrain` CLI talks to local PGLite
for code-def/refs/callers).
**If B (No)**: skip the install + init. The local engine stays absent.
`gbrain_local_status` will be `missing-config` (or `no-cli` if gbrain isn't
installed). `/sync-gbrain` will SKIP the code stage cleanly per plan D12.
**4e. Skip Steps 3, 4 (other paths) and 5 (local doctor) when B was picked.**
When A was picked, Step 3 already ran (via gstack-gbrain-install) and Step 4
already ran (via `gbrain init --pglite`); jump straight to Step 5a. When B
was picked, Steps 3/4/5 are no-ops; also skip Step 7.5 (transcript ingest)
since memory-stage routes through the artifacts pipeline in remote-http mode
per plan D11.
The bearer token (`GBRAIN_MCP_TOKEN`) stays in process env until Step 5a's
`claude mcp add --header` consumes it; then `unset GBRAIN_MCP_TOKEN`
immediately. Token security trade-off documented in
`setup-gbrain/memory.md`: brief argv exposure during `claude mcp add`,
resting state in `~/.claude.json` mode 0600.
### Switch (from detect's existing-engine state)
```bash
# Going PGLite → Supabase, collect URL first (Path 1 flow), then:
timeout 180s gbrain migrate --to supabase --url "$URL" --json
# Going Supabase → PGLite:
timeout 180s gbrain migrate --to pglite --json
```
If `timeout` returns 124 (exit code for timeout): surface D9 message
("Migration didn't complete in 3 minutes — another gstack session may be
holding a lock on the source brain. Close other workspaces and re-run
`/setup-gbrain --switch`. Your original brain is untouched."). STOP.

### Path 1 (Supabase, existing URL)
Source the secret-read helper, collect URL with `read -s` + redacted preview:
```bash
. ~/.claude/skills/gstack/bin/gstack-gbrain-lib.sh
read_secret_to_env GBRAIN_POOLER_URL "Paste Session Pooler URL: " \

Then validate structurally:
```bash
printf '%s' "$GBRAIN_POOLER_URL" | ~/.claude/skills/gstack/bin/gstack-gbrain-supabase-verify -
```
If the verify exit code is 3 (direct-connection URL), the verifier's own
message explains the fix; surface it and re-prompt for a Session Pooler URL.
On success, hand off to gbrain via env var (D10, never argv):

**After Step 9 (smoke test) passes, also write the `## GBrain Search Guidance`

block is gated on the smoke test passing — write the Configuration block
first (so the user knows what state they're in even if the smoke test fails),
then return here after Step 9 and write the guidance block only if smoke
test succeeded.

```markdown
## GBrain Search Guidance (configured by /sync-gbrain)
<!-- gstack-gbrain-search-guidance:start -->
GBrain is set up and synced on this machine. The agent should prefer gbrain
over Grep when the question is semantic or when you don't know the exact
identifier yet. Two indexed corpora available via the `gbrain` CLI:
- This repo's code (registered as `gstack-code-<repo>` source).
- `~/.gstack/` curated memory (registered as `gstack-brain-<user>` source via
the existing federation pipeline).
Prefer gbrain when:
- "Where is X handled?" / semantic intent, no exact string yet:
`gbrain search "<terms>"` or `gbrain query "<question>"`
- "Where is symbol Y defined?" / symbol-based code questions:
`gbrain code-def <symbol>` or `gbrain code-refs <symbol>`
- "What calls Y?" / "What does Y depend on?":
`gbrain code-callers <symbol>` / `gbrain code-callees <symbol>`
- "What did we decide last time?" / past plans, retros, learnings:

- MCP URL: {MCP_URL}
- Server version: gbrain v{SERVER_VERSION} (from Step 4c verify)
- Setup date: {today}
- MCP registered: yes (user scope)
- Token: stored in ~/.claude.json (do not commit; never written to CLAUDE.md)

- Current repo policy: {read-write|read-only|deny|unset}

The bearer token is **never** written to CLAUDE.md (CLAUDE.md is checked

`claude mcp add` placed it.

**After Step 9 (smoke test) passes, also write the `## GBrain Search Guidance`
block** so the coding agent learns when to prefer `gbrain` over Grep. This
block is gated on the smoke test passing — write the Configuration block
first (so the user knows what state they're in even if the smoke test fails),
then return here after Step 9 and write the guidance block only if smoke
test succeeded.
When Step 9 passes, find-and-replace (or append) this block. Use HTML-comment
delimiters so removal regex is unambiguous and never eats user content. The
block content is machine-AGNOSTIC — no engine type, no page counts, no
last-sync time. Machine state stays in the Configuration block above.
```markdown
## GBrain Search Guidance (configured by /sync-gbrain)
<!-- gstack-gbrain-search-guidance:start -->
GBrain is set up and synced on this machine. The agent should prefer gbrain
over Grep when the question is semantic or when you don't know the exact
identifier yet. Two indexed corpora available via the `gbrain` CLI:
- This repo's code (registered as `gstack-code-<repo>` source).
- `~/.gstack/` curated memory (registered as `gstack-brain-<user>` source via
the existing federation pipeline).
Prefer gbrain when:
- "Where is X handled?" / semantic intent, no exact string yet:
`gbrain search "<terms>"` or `gbrain query "<question>"`
- "Where is symbol Y defined?" / symbol-based code questions:
`gbrain code-def <symbol>` or `gbrain code-refs <symbol>`
- "What calls Y?" / "What does Y depend on?":
`gbrain code-callers <symbol>` / `gbrain code-callees <symbol>`
- "What did we decide last time?" / past plans, retros, learnings:
`gbrain search "<terms>" --source gstack-brain-<user>`
Grep is still right for known exact strings, regex, multiline patterns, and
file globs. The brain auto-syncs incrementally on every gstack skill start.

### Step 1.5 remediation: broken-engine AskUserQuestion + repair branches
The user has a non-working local engine (Garry's repro: `~/.gbrain/config.json`
points at a dead Postgres URL). Fire a targeted AskUserQuestion BEFORE Step 2:
> D# — Your local gbrain engine isn't responding. How do you want to fix it?
> Project/branch/task: <one-sentence grounding using detected slug + branch>
> ELI10: gbrain has a config at `~/.gbrain/config.json` but the engine it points
> at isn't reachable. That could be a transient outage (Postgres container
> stopped, Tailscale down) OR a stale config you want to abandon. Different
> remediation for each case.
> Stakes if we pick wrong: "Switch to PGLite" overwrites your existing config
> (one-way door if the user actually wanted the broken engine). "Retry" preserves
> existing state for transient cases.
> Recommendation: A (Retry) — always try the cheap option first; if engine is
> just temporarily down it'll come back without any destructive change.
> Note: options differ in kind, not coverage — no completeness score.
> A) Retry — re-probe the engine (recommended; ~80ms)
> ✅ Cheapest test: re-runs `gbrain sources list` to see if engine is back
> ✅ Zero side effects; existing config preserved
> ❌ If engine is permanently dead, retries forever; user must choose another option
> B) Switch to local PGLite (one-way — moves existing config to .bak)
> ✅ Fastest path to a working local engine if user has abandoned the old one
> ✅ ~30s; no accounts; private to this machine
> ❌ Destructive — existing config moved to ~/.gbrain/config.json.gstack-bak-{ts}
> C) Switch brain mode (continue to Step 2 path picker)
> ✅ Lets user pick Path 1/2/3/4 to re-init from scratch
> ✅ Preserves existing config until they explicitly init the new one
> ❌ Longer flow if user just wants to repair to PGLite
> D) Quit (do nothing)
> ✅ No cons — this is a hard-stop choice
> ❌ N/A
> Net: A is the right starting move; B/C are explicit destructive paths; D bails.
**If A (Retry)**: re-run `~/.claude/skills/gstack/bin/gstack-gbrain-detect`

`gbrain_local_status` is `ok`, continue to Step 2. If still `broken-db` or
`broken-config`, fire the same AskUserQuestion again (the user picks again).
**If B (Switch to PGLite)** — execute the rollback-safe init sequence (plan D7):

exit 1

echo "Switched to local PGLite. Previous config saved at $BACKUP — review before deleting."

Then jump to Step 5a (MCP registration; the new PGLite engine is registered as

*
* Monolith-tolerant: if the generated SKILL.md has no STOP pointers (pre-carve
