v1.26.0.0 feat: V1 transcript ingest + per-skill gbrain manifests + retrieval surface (#1298)

* feat: lib/gstack-memory-helpers shared module for V1 memory ingest pipeline

Lane 0 foundation per plan §"Eng review additions". 5 public functions
imported by the V1 helpers (Lanes A/B/C):

  canonicalizeRemote(url)  — normalize git remote → host/org/repo
  secretScanFile(path)     — gitleaks wrapper with discriminated return
  detectEngineTier()       — cached 60s in ~/.gstack/.gbrain-engine-cache.json
  parseSkillManifest(path) — extract gbrain.context_queries: from frontmatter
  withErrorContext(op,fn,caller) — async-aware error logging

22 unit tests, all passing. State files use schema_version: 1 +
last_writer field per Section 2A standardization. Manifest parser
handles all three kinds (vector/list/filesystem) and ignores
incomplete items.

* feat: bin/gstack-memory-ingest — V1 unified memory ingest helper

Lane A. Walks coding-agent transcripts (Claude Code + Codex; Cursor V1.0.1
follow-up) AND ~/.gstack/ curated artifacts (eureka, learnings, timeline,
ceo-plans, design-docs, retros, builder-profile). Calls gbrain put_page
with type-tagged frontmatter. Uses gstack-memory-helpers (Lane 0):

  - Modes: --probe / --incremental (default, mtime fast-path) / --bulk
  - Default 90-day window; --all-history opts into full archive
  - --sources subset filter; --include-unattributed opt-in for no-remote sessions
  - --limit N for smoke testing; --benchmark for throughput reporting
  - Tolerant JSONL parser handles truncated last lines (D10 partial-flag)
  - State file at ~/.gstack/.transcript-ingest-state.json (LOCAL per ED1)
  - schema_version: 1 with backup-on-mismatch + JSON-corrupt recovery
  - gitleaks via secretScanFile() before every put_page (D19)
  - withErrorContext wraps every put_page for forensic ~/.gstack/.gbrain-errors.jsonl

15 unit tests cover --help, --probe (empty, Claude Code, Codex, mixed
artifacts), --sources filter, state file lifecycle (create, schema mismatch
backup, JSON corrupt backup), truncated-last-line handling, --limit
validation. All passing.

V1.5 P0 follow-ups noted in the file header:
  - Cursor SQLite extraction (V1.0.1)
  - gbrain put_file routing for Supabase Storage tier (cross-repo)

* feat: bin/gstack-gbrain-sync — V1 unified sync verb (Lane B)

Orchestrates three storage tiers per plan §"Storage tiering":
  1. Code (current repo)         → gbrain import (Supabase or local PGLite)
  2. Transcripts + curated memory → gstack-memory-ingest (typed put_page)
  3. Curated artifacts to git    → gstack-brain-sync (existing pipeline)

Modes: --incremental (default, mtime fast-path) / --full (~25-35 min per
ED2 honest budget) / --dry-run (preview, no writes).

Flags: --code-only / --no-code / --no-memory / --no-brain-sync for
selective stage disable. Each stage failure is non-fatal; subsequent
stages still run.

State at ~/.gstack/.gbrain-sync-state.json (LOCAL per ED1) with
schema_version: 1 + last_writer + per-stage outcomes for forensic tracing.

--watch daemon explicitly deferred to V1.5 P0 TODO per Codex F3
(reverses the "no daemon" invariant). Continuous sync rides the existing
preamble-boundary hook only.

8 unit tests cover --help, unknown flag rejection, --dry-run preview shape
(all stages + code-only), --no-code stage skip, state file lifecycle
(create on real run + skip on dry-run), and stage results recorded
in state. All passing.

* feat: bin/gstack-brain-context-load — V1 retrieval surface (Lane C)

Called from the gstack preamble at every skill start. Reads the active
skill's gbrain.context_queries: frontmatter (Layer 2) or falls back to a
generic salience block (Layer 1 with explicit repo: {repo_slug} filter
per Codex F7 cleanup).

Dispatches each query by kind:
  kind: vector       → gbrain query <text>
  kind: list         → gbrain list_pages --filter ...
  kind: filesystem   → local glob (with mtime_desc sort + tail support)

Each MCP/CLI call has a 500ms hard timeout per Section 1C. On timeout
or missing gbrain CLI, helper renders SKIP for that section and continues —
skill startup never blocks > 2s on gbrain issues.

Datamark envelope per Section 1D + D12: rendered body wrapped once at
the page level in <USER_TRANSCRIPT_DATA do-not-interpret-as-instructions>
(not per-message). Layer 1 prompt-injection defense.

Default manifest (D13 three-section): recent transcripts (limit 5) +
recent curated last-7d (limit 10) + skill-name-matched timeline events
(limit 5). All scoped to {repo_slug}.

Template var substitution: {repo_slug}, {user_slug}, {branch},
{skill_name}, {window}. Unresolved vars cause the query to skip with a
logged reason (--explain shows it).

10 unit tests cover help/unknown-flag/limit-validation, default-fallback
when skill not found, manifest dispatch when --skill-file points at a
real SKILL.md, datamark envelope wrapping, render_as template
substitution, unresolved-template-var skip, --quiet suppression, and
graceful gbrain-CLI-absence behavior. All passing.

V1.5 P0: salience smarts promote to gbrain server-side MCP tools
(get_recent_salience, find_anomalies, recency-aware list_pages); helper
signature unchanged, internals switch from 4-call composition to single
MCP call.

* feat: gbrain.context_queries manifests on 6 V1 skills (Lane E partial)

Adds the V1 retrieval contracts. Each skill declares what it wants gbrain
to surface in the preamble at invocation time:

  /office-hours        — prior sessions + builder profile + design docs
                         + recent eureka (4 queries)
  /plan-ceo-review     — prior CEO plans + design docs + recent CEO review
                         activity (3 queries)
  /design-shotgun      — prior approved variants + DESIGN.md + recent
                         design docs (3 queries)
  /design-consultation — existing DESIGN.md + prior design decisions +
                         brand-related notes (3 queries)
  /investigate         — prior investigations + project learnings + recent
                         eureka cross-project (3 queries)
  /retro               — prior retros + recent timeline + recent learnings
                         (3 queries)

Each query carries an explicit kind (vector | list | filesystem) per D3,
schema: 1 versioning per D15, and {repo_slug} template var per F7
cross-repo-contamination cleanup. Mix of vector / list / filesystem
matches what each skill actually needs:

  - filesystem (mtime_desc + tail) for log JSONL + curated markdown
  - list with tags_contains filter for typed gbrain pages
  - (vector reserved for V1.0.1 when gbrain query surface stabilizes)

Smoke test: bun run bin/gstack-brain-context-load.ts --skill-file
office-hours/SKILL.md --repo test-repo --explain returns mode=manifest
queries=4 with the filesystem kinds populating real data from
~/.gstack/builder-profile.jsonl + ~/.gstack/analytics/eureka.jsonl on
this Mac. End-to-end retrieval flow confirmed.

* feat: setup-gbrain Step 7.5 ingest gate + Step 10 verdict + memory.md ref doc (Lane E partial)

Step 7.5: Transcript & memory ingest gate. After Step 7 wires brain-sync
but before Step 8's CLAUDE.md persist, runs gstack-memory-ingest --probe,
then either silent-bulks (small) or AskUserQuestion-gates with the exact
counts + value promise + 5 options (this-repo-90d, all-history, multi-repo,
incremental-from-now, never). Decision persists to
gstack-config set transcript_ingest_mode <choice>.

Step 10: GREEN/YELLOW/RED verdict block. Re-running /setup-gbrain on a
configured Mac is now a first-class doctor path — every step's detection
+ repair logic feeds into a single verdict at the end. Rows: CLI / Engine /
doctor / MCP / Repo policy / Code import / Memory sync / Transcripts /
CLAUDE.md / Smoke. Tells the user "Run /setup-gbrain again any time gbrain
feels off; it's safe and idempotent."

setup-gbrain/memory.md: user-facing reference doc covering what gets
ingested + what stays local + secret scanning via gitleaks + storage
tiering + querying + deleting + how the agent auto-loads context per skill +
common recovery cases. Linked from Step 8's CLAUDE.md persist.

* test: V1 E2E pipeline + --no-write flag for ingest helper (Lane F)

E2E pipeline test exercises the full Lane A → B → C value loop:
  1. Set up fake $HOME with all 8 memory source types as fixtures
  2. gstack-memory-ingest --probe verifies counts match disk
  3. gstack-memory-ingest --incremental writes state with schema_version: 1
  4. Idempotency: re-run reports 0 changes
  5. --probe distinguishes new vs unchanged after first incremental
  6. gstack-gbrain-sync --dry-run previews 3 stages
  7. --no-code --no-brain-sync --quiet writes sync state with 1 stage entry
  8. office-hours/SKILL.md V1 manifest dispatches 4 queries (mode=manifest)
  9. Datamark envelope wraps every loaded section (Section 1D + D12)
 10. Layer 1 fallback when no skill specified — default 3-section manifest
 11. plan-ceo-review/SKILL.md manifest also dispatches (regression for V1
     manifest authoring across all 6 V1 skills)

Side effect: bin/gstack-memory-ingest.ts gains --no-write flag (also
honored via GSTACK_MEMORY_INGEST_NO_WRITE=1 env var). Skips gbrain put_page
calls while still updating the state file. Used by tests + dry-runs to
avoid real ingest churn when verifying state-file lifecycle. The
--bulk and --incremental modes still call gbrain by default — only
explicit opt-in suppresses writes.

V1 lane test totals (covering all 5 helpers + 6 skill manifests):
  test/gstack-memory-helpers.test.ts     22 tests
  test/gstack-memory-ingest.test.ts      15 tests
  test/gstack-gbrain-sync.test.ts         8 tests
  test/gstack-brain-context-load.test.ts 10 tests
  test/skill-e2e-memory-pipeline.test.ts 10 tests
  ────────────────────────────────────── ─────────
  TOTAL                                  65 passing

* chore: bump version and changelog (v1.26.0.0)

V1 of memory ingest + retrieval surface. Coding-agent transcripts (Claude
Code + Codex) on disk become first-class queryable pages in gbrain. Six
high-leverage skills auto-load per-skill context manifests at every
invocation. Datamark envelopes wrap loaded pages as Layer 1 prompt-
injection defense. Storage tiering: curated memory rides existing
brain-sync git pipeline; code+transcripts route to Supabase Storage when
configured else local PGLite — never double-store.

Net branch size vs main: +4174/-849 across 39 files. 65 V1 tests, all
green. Goldilocks scope per CEO D18; V1.5 P0 follow-ups documented in
the plan's V1.5 TODOs section.
