1dadd9ed71 v0.35.7.0 feat: temporal trajectory + founder scorecard (Phases 2-4) (#1131 )

* feat(facts): typed-claim substrate + cycle correctness fixes (v0.35.6 wave 1/3)

Schema (migration v67):
- Add four optional typed-claim columns to facts: claim_metric TEXT,
  claim_value DOUBLE PRECISION, claim_unit TEXT, claim_period TEXT
- Partial index facts_typed_claim_idx ON (entity_slug, claim_metric, valid_from)
  WHERE claim_metric IS NOT NULL
- All nullable, metadata-only on both engines

Fence layer:
- ParsedFact (facts-fence.ts) gains optional claimMetric/Value/Unit/Period
- Parser tolerates both 10-cell (legacy) and 14-cell (widened) rows
- Renderer emits 14 cells iff any row has typed data; otherwise stays
  10-cell so existing fences don't widen on unrelated edits
- Numeric value cell tolerates comma thousand separators (50,000 -> 50000)

Extract pipeline (D-CDX-2, D-ENG-1):
- src/core/facts/extract.ts (the actual Haiku call site, NOT extract-facts.ts
  cycle phase) extends its system prompt to emit typed fields for metric-shaped
  claims
- extractFactsFromFenceText gains optional pageEffectiveDate. Precedence:
  fence-row validFrom > pageEffectiveDate > undefined (engine defaults to now)
- normalizeMetricLabel: 15-entry seed map for common founder metrics (mrr,
  arr, runway, headcount, team_size, cac, ltv, gross_margin, burn_rate, cash,
  users, mau, dau, churn_rate, revenue); unknown labels lowercase + space->_

Engine extensions:
- NewFact + insertFact + insertFacts in both engines accept the four typed
  columns (all nullable)
- Cycle phase extract-facts.ts threads page.effective_date through AND
  batch-embeds via gateway.embed() before insertFacts (D-CDX-3 fix for
  cycle-inserted facts arriving with embedding=NULL)

Consolidate fix (D-CDX-4 — Codex F4):
- Replace MAX(row_num)+1 INSERT with semantic upsert on (page_id, claim,
  since_date). Re-running the full cycle on stable input produces zero new
  takes — fixes the pre-existing duplicate-takes bug after extract_facts
  wipes consolidated_at
- Chronological valid_until writeback per cluster: sort by (valid_from ASC,
  id ASC), walk pairs, set older.valid_until = newer.valid_from

Tests:
- test/migrate.test.ts +6 cases for v67 shape + materialization + nullable
  backward compat
- test/facts-fence-typed.test.ts (new, 17 cases): parser+renderer round-trip,
  normalization seed map coverage, valid_from precedence three-branch
- test/consolidate-valid-until.test.ts (new, 4 cases): chronological
  writeback (R4a), same-day id tiebreaker, cycle re-run zero duplicates
  (R4b/R7), valid_until idempotency
- test/schema-bootstrap-coverage.test.ts: add four typed-claim columns to
  COLUMN_EXEMPTIONS (migration co-defines the partial index, no forward
  reference to bootstrap)

* feat(trajectory): find_trajectory MCP op + eval/founder CLIs (v0.35.6 wave 2/3)

Engine method (D-CDX-1, D-CDX-6):
- BrainEngine.findTrajectory(opts) on both Postgres and PGLite
- TrajectoryOpts: scalar sourceId fast path + sourceIds federated array
  (mirrors v0.34.1.0 search* dual pattern)
- opts.remote: when true, SQL adds AND visibility='world' so OAuth read
  clients see only world-visibility facts (mirrors recall's posture —
  closes the F7 privacy regression Codex caught in plan review)
- Single SQL query, ORDER BY valid_from ASC, id ASC for deterministic
  output (R3 pin). Returns TrajectoryPoint[] including raw embedding so
  the caller can compute drift without a second round-trip

Pure function library (src/core/trajectory.ts, new):
- detectRegressions(points, threshold): walks consecutive (metric, value)
  pairs per metric; emits when newer drops >= threshold below older.
  10% default, override via GBRAIN_TRAJECTORY_REGRESSION_THRESHOLD
- computeDriftScore(points): 1 - mean(cosine(emb[i], emb[i-1])) over
  embedded points; clamped [0,1]; null when <3 embedded points (D-ENG-3
  graceful degradation)
- computeTrajectoryStats(points): composed shape returning both
- TRAJECTORY_SCHEMA_VERSION = 1 — additive-only across releases (R5)

MCP op (src/core/operations.ts):
- find_trajectory: scope read, NOT localOnly. Routes through
  sourceScopeOpts(ctx) for federated isolation AND threads ctx.remote
  for visibility filtering. Strips raw Float32Array embeddings from the
  wire shape; converts valid_from to YYYY-MM-DD string
- Registered in operations array after find_experts
- FIND_TRAJECTORY_DESCRIPTION in operations-descriptions.ts

CLIs:
- gbrain eval trajectory <entity> [--metric M] [--since D] [--until D]
  [--limit N] [--json] — chronological human view with [REGRESSION] inline
  annotation; thin-client routing via callRemoteTool(find_trajectory).
  Dispatched in src/commands/eval.ts sub-subcommand block
- gbrain founder scorecard <entity> [--since D] [--until D] [--json] —
  pure aggregation over Phase 2's substrate. Four signals:
  claim_accuracy (over resolved takes), consistency, growth_trajectory,
  red_flags. computeFounderScorecard exported for tests.
  Registered as top-level command in cli.ts; added to CLI_ONLY set

Tests (45 cases across 5 files):
- test/engine-find-trajectory.test.ts: 18 cases — chronological order,
  source scoping (scalar + federated), visibility filter on remote=true,
  metric + since/until filters, regression detection at threshold
  boundaries, drift score with various embedding states
- test/operations-find-trajectory.test.ts: 9 cases — op registration,
  param validation, JSON envelope shape, R5 schema_version: 1,
  embedding stripped from wire, R6 visibility filter, source scoping
- test/eval-trajectory.test.ts: 7 cases — arg parsing, --help,
  --json envelope, regression annotation, --metric filter, empty entity
- test/founder-scorecard.test.ts: 9 cases — empty inputs no-NaN (G2),
  claim_accuracy math, consistency math, growth_trajectory math,
  red_flags fire for regression / narrative_drift / missed_prediction
- test/eval-contradictions/no-valid-until-write.test.ts: 4 cases —
  R1 (probe never writes valid_until under eval-contradictions/) +
  R8 (only allow-listed files write valid_until anywhere in src/)

* chore: v0.35.6.0 — CHANGELOG + VERSION + docs + migration note

Bumps to v0.35.6.0 (next-minor after master's v0.35.5.1 — typed-claim
substrate + trajectory + founder scorecard is a new user-facing
feature surface, not a fix).

- VERSION + package.json synced
- CHANGELOG.md release-summary block in the wave-style voice, lead with
  what the user can now DO. Sections: typed metric claims in the fence,
  chronological metric trajectories, founder scorecard, MCP
  find_trajectory op, cycle re-run idempotency fix, embedding-on-insert
  fix, valid_from precedence fix. To-take-advantage-of block with
  verification + opt-in fence syntax example
- CLAUDE.md Key Files entry consolidating the wave across
  eval-trajectory.ts + founder-scorecard.ts + trajectory.ts. Names every
  D-ENG / D-CDX decision and the Codex outside-voice F-numbers
- skills/migrations/v0.35.6.md agent-readable migration note. Includes
  fence-syntax example for typed-claim rows so downstream agents start
  emitting them. Iron-rule contracts called out (R1 + R8 + R7 + visibility)
- llms-full.txt regenerated to reflect the new CLAUDE.md entry

* docs: post-ship sync for v0.35.7.0 — trajectory + founder scorecard

- README.md: add `gbrain eval trajectory` to EVAL section, add new
  TEMPORAL block covering `gbrain founder scorecard` + the
  GBRAIN_TRAJECTORY_REGRESSION_THRESHOLD env override; add v0.35.7
  "What's new" paragraph below the v0.28.8 LongMemEval blurb
- AGENTS.md: new bullet under Common tasks teaching agents to reach for
  `gbrain eval trajectory` / `gbrain founder scorecard` / the
  `find_trajectory` MCP op when asked to evaluate a founder/company
  over time
- docs/contradictions.md: append "Temporal axis follow-on (v0.35.3.1 +
  v0.35.7)" subsection under See also, cross-linking the trajectory
  substrate and naming the auto-supersession.ts:4 invariant preserved
  by both the verdict enum (probe side) and consolidate's valid_until
  writeback (cycle side)
- CLAUDE.md: fix stale (v0.35.4) tag on the trajectory entry to
  (v0.35.7) — version got rebumped twice during the merge wave
- skills/migrations/v0.35.7.md renamed to v0.35.7.0.md for consistency
  with the v0.35.0.0.md / v0.14.0.md / etc naming convention
- llms-full.txt regenerated to reflect the CLAUDE.md edit

Coverage map (Diataxis):
  /eval trajectory CLI       ✅ ref (README, AGENTS) ✅ how-to (CHANGELOG) ❌ tutorial
  /founder scorecard CLI     ✅ ref (README, AGENTS) ✅ how-to (CHANGELOG) ❌ tutorial
  find_trajectory MCP op     ✅ ref (CLAUDE.md, AGENTS, contradictions.md)
  typed-claim fence cols     ✅ ref (skills/migrations/v0.35.7.0.md, CHANGELOG)
  Migration v67              ✅ ref (CLAUDE.md, CHANGELOG)

No tutorial / explanation gaps worth filling in this PR — the migration
note's fence-syntax example already covers the "first typed claim"
walkthrough. ARCHITECTURE diagrams not drifted (the trajectory work
extends existing facts/takes infrastructure; no new component boxes).

Raw Blame History

Agents working on GBrain

This is your install + operating protocol. Claude Code reads ./CLAUDE.md automatically. Everyone else (Codex, Cursor, OpenClaw, Aider, Continue, or an LLM fetching via URL): start here.

Install (5 min)

Clone: git clone https://github.com/garrytan/gbrain ~/gbrain && cd ~/gbrain
Install: bun install
Init the brain: gbrain init (defaults to PGLite, zero-config). For 1000+ files or multi-machine sync, init suggests Postgres + pgvector via Supabase.
STOP — ask the user about search mode. gbrain init auto-applied a default but printed a 9-cell cost matrix (mode × downstream model) preceded by [AGENT] markers. You MUST relay the matrix to the operator and confirm their choice before continuing. Cost spread between corners is 25x — silent acceptance is the wrong default. See ./INSTALL_FOR_AGENTS.md Step 3.5 for the exact ask-the-user protocol. Same banner fires on gbrain post-upgrade for existing users (search modes were added in v0.32.3).
Read ./INSTALL_FOR_AGENTS.md for the full 9-step flow (API keys, identity, cron, verification).

Read this order

./AGENTS.md (this file) — install + operating protocol.
./CLAUDE.md — architecture reference, key files, trust boundaries, test layout.
./docs/architecture/brains-and-sources.md — the two-axis mental model (brain = which DB, source = which repo in the DB). Every query routes on both axes. Read before writing anything that touches brain ops.
./skills/conventions/brain-routing.md — agent-facing decision table: when to switch brain, when to switch source, how cross-brain federation works (latent-space only; the agent decides).
./skills/RESOLVER.md — skill dispatcher. Read before any task.

Trust boundary (critical)

GBrain distinguishes trusted local CLI callers (OperationContext.remote = false, set by src/cli.ts) from untrusted agent-facing callers (remote = true, set by src/mcp/server.ts). Security-sensitive operations like file_upload tighten filesystem confinement when remote = true and default to strict behavior when unset. If you are writing or reviewing an operation, consult src/core/operations.ts for the contract.

Common tasks

Configure: docs/ENGINES.md, docs/guides/live-sync.md, docs/mcp/DEPLOY.md.
Debug: docs/GBRAIN_VERIFY.md, docs/guides/minions-fix.md, gbrain doctor --fix.
Migrate: docs/UPGRADING_DOWNSTREAM_AGENTS.md, skills/migrations/, gbrain apply-migrations.
Eval retrieval changes: capture is off by default. To benchmark a retrieval change against real captured queries, set GBRAIN_CONTRIBUTOR_MODE=1, then gbrain eval export --since 7d > base.ndjson and gbrain eval replay --against base.ndjson. For public benchmark coverage (LongMemEval, ground-truth scoring), gbrain eval longmemeval <dataset.jsonl> (v0.28.8) runs against an isolated in-memory PGLite per question — your ~/.gbrain is never opened. Full guide: docs/eval-bench.md.
Track a founder/company over time (v0.35.7): when an entity has typed metric claims in its ## Facts fence (metric: mrr, value: 50000, unit: USD, period: monthly columns), run gbrain eval trajectory <entity-slug> for the chronological history with regressions auto-flagged, or gbrain founder scorecard <entity-slug> for a four-signal JSON rollup (claim_accuracy / consistency / growth_trajectory / red_flags). MCP op find_trajectory exposes the same data — read scope, visibility-filtered for remote callers.
Everything else: ./llms.txt is the full documentation map. ./llms-full.txt is the same map with core docs inlined for single-fetch ingestion.

Before shipping

Easiest path: bun run ci:local runs the full CI gate inside Docker (gitleaks, unit tests with DATABASE_URL unset, then all 29 E2E files sequentially against a fresh pgvector container) and tears down. Use bun run ci:local:diff for the diff-aware subset during fast iteration on a focused branch. Requires Docker (Docker Desktop / OrbStack / Colima) and gitleaks (brew install gitleaks).

Manual path: bun test plus the E2E lifecycle described in ./CLAUDE.md (spin up the test Postgres container, run bun run test:e2e, tear it down).

Ship via the /ship skill, not by hand.

Privacy

Never commit real names of people, companies, or funds into public artifacts. See the Privacy rule in ./CLAUDE.md. GBrain pages reference real contacts; public docs must use generic placeholders (alice-example, acme-example, fund-a).

Forks

If you are a fork, regenerate llms.txt + llms-full.txt with your own URL base before publishing: LLMS_REPO_BASE=https://raw.githubusercontent.com/your-org/your-fork/main bun run build:llms.
