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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * 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.

+ * E2E pipeline test for V1 memory ingest + retrieval surface.
+ *
+ * Exercises the full Lane A → Lane B → Lane C value loop end-to-end:
+ *
+ *   1. Set up a fake $HOME with a Claude Code project + a Codex session +
+ *      ~/.gstack/ artifacts (eureka, learning, ceo-plan, design-doc, retro,
+ *      builder-profile)
+ *   2. Run gstack-memory-ingest --probe → verify counts match disk
+ *   3. Run gstack-memory-ingest --bulk → verify state file gets written +
+ *      session_id dedup works on re-run (idempotency)
+ *   4. Run gstack-gbrain-sync --dry-run → verify all 3 stages preview
+ *   5. Run gstack-brain-context-load against a real V1 skill manifest
+ *      (office-hours/SKILL.md) → verify the manifest dispatches all 4
+ *      queries with the datamark envelope
+ *
+ * Each assertion targets a specific plan acceptance criterion (D10, D11,
+ * D12, ED1, ED2, F7, Section 1C/1D, Section 6 regression #3).
+ *
+ * NOTE: The "write to gbrain" path is non-asserting because gbrain MCP
+ * may or may not be available in CI. We assert on side effects gstack
+ * itself can verify: state file shape, exit codes, rendered output, and
+ * mtime-based incremental fast-path correctness.
