 		cdba533a04 v0.36.2.0 feat: ZeroEntropy as default + zero-based README rewrite (#1136) 
* feat(dims): OpenAI text-embedding-3 Matryoshka range validation (D13)

dimsProviderOptions now fail-loud at the embed boundary when the
configured embedding_dimensions is outside the model's native range
(1..1536 for -small, 1..3072 for -large). Paste-ready fix hint in the
AIConfigError.fix field. Closes the silent-HTTP-400 path that would
have bit OpenAI-fallback users on v0.36.0.0 ZE-default installs.

16 new test cases in test/ai/dims-openai.test.ts pinning the contract
across native-openai and openai-compatible adapter paths.

* feat(ai): flip defaults to ZeroEntropy zembed-1 1280d + zerank-2 reranker

Default embedding model is now zeroentropyai:zembed-1 at 1280d via
Matryoshka. Real-corpus benchmark: 2.2x faster than OpenAI, 2.6x
cheaper at regular pricing, wins 11/20 head-to-head queries.

1280 is the closest valid ZE Matryoshka step to the prior OpenAI 1536d
default (valid set: 2560/1280/640/320/160/80/40). 1024 (Voyage's step)
is NOT on ZE's list — pinned by AIConfigError fail-loud in dims.ts.

balanced mode bundle now defaults reranker_enabled=true. zerank-2
reshuffles 60% of top-1 results in benchmarks. Missing-key fail-open
contract in src/core/search/rerank.ts handles unauthenticated cases.
Opt out with: gbrain config set search.reranker.enabled false

Existing tests updated (gateway.test.ts, search-mode.test.ts) and a
new test/balanced-reranker-default.test.ts (10 cases) pins the fail-
open invariants.

* feat(retrieval-upgrade): RetrievalUpgradePlanner + interactive prompt UX

New src/core/retrieval-upgrade-planner.ts is the consolidated planner
that computes the brain's pending retrieval-upgrade work (chunker
bumps + ZE switch) in one pass and applies the schema transition +
config updates atomically.

Tagged-union ApplyResult enum (D15): 'applied' | 'skipped_already_
applied' | 'skipped_no_work' | 'declined' | 'planned' | 'failed'.
No string-parsing reasons.

Three config keys (D12): ze_switch_prompt_shown (UI state),
ze_switch_requested (user intent), ze_switch_applied (work done).
Plus ze_switch_previous_snapshot (JSON, full prior config for --undo
per D16) and ze_switch_declined_at (90-day re-ask window).

Schema transition (D18) is atomic: DROP indexes + ALTER COLUMN +
CREATE INDEX inside a single engine.transaction(). HNSW recreation
is part of the same transaction — no silent slow-search window.

C3 eligibility logic: ze_switch_offered iff NOT on ZE + NOT declined
recently + NOT applied + (legacy default OR >100 pages).

C4 cost math: MAX(chunker_pending, dim_pending) not SUM — one
re-embed pass invalidates both surfaces simultaneously.

New src/core/retrieval-upgrade-prompt.ts wires the planner to a
TTY-only interactive prompt with two-line cost split (D10) and
privacy callout for the reranker flip.

Tests: test/retrieval-upgrade-planner.test.ts (24 cases) pins the
state machine. test/asymmetric-encoding-contract.test.ts (6 cases)
pins D17: search read path uses gateway.embedQuery() not embed(),
asserted via __setEmbedTransportForTests mock.

* feat(cli): gbrain ze-switch — manual lever for the ZE switch

New gbrain ze-switch CLI with --dry-run, --json, --resume, --force,
--undo, --non-interactive, --confirm-reembed, --ignore-missing-key
flags. Mirrors the upgrade prompt's UX symmetry: --undo presents a
cost-warning before re-embedding back to the prior width.

src/cli.ts: dispatch case + CLI_ONLY entry. ze-switch owns its own
engine lifecycle (mirrors the doctor pattern).

test/ze-switch-cli.test.ts (11 cases): --help, --dry-run, --json,
--non-interactive, --ignore-missing-key, --resume, --undo,
--confirm-reembed. Uses captureExit harness to test process.exit()
paths without breaking the test process.

* feat(doctor): ze_embedding_health + embedding_width_consistency checks

Two new doctor checks (D-A5):

ze_embedding_health: when embedding_model starts with zeroentropyai:,
verify ZEROENTROPY_API_KEY is set (env or config). Paste-ready setup
hint with the signup URL on failure.

embedding_width_consistency: cross-check that the configured
embedding_dimensions matches the actual vector(N) column width on
content_chunks.embedding. Catches the half-applied switch state
(schema migrated but config write crashed) with a paste-ready
gbrain ze-switch --resume hint.

Wired into runDoctor between reranker_health and the existing
sync_freshness checks. Both checks gracefully no-op on non-ZE
embedding configs.

test/doctor-ze-checks.test.ts (8 cases) pins both checks across
happy + missing-key + missing-config + drift paths. Uses withEnv()
helper to clear ZEROENTROPY_API_KEY for the no-key path so tests
are hermetic against contributor env state.

test/e2e/v0_28_5-fix-wave.test.ts + test/openai-compat-multimodal.test.ts:
updated to explicit-configure the gateway when the test depends on
specific dims that diverge from the v0.36.0.0 default (1280d).

* docs: README zero-based rewrite (884 -> 139 lines) + new docs files

Strip 4 months of accreted "New in v0.X.Y" hero blocks and reorganize
around what gbrain does today. 33 H2s -> 8. The Commands section
(136 lines duplicating gbrain --help) moved out; the 6-table skills
enumeration collapsed to a one-paragraph capability description with
a link to skills/RESOLVER.md.

Hero retains load-bearing facts: OpenClaw + Hermes credit, production
numbers (17,888 pages / 4,383 people / 723 companies), BrainBench
numbers (P@5 49.1% / R@5 97.9% / +31.4 lift), ZE comparison numbers,
30-min install claim. Adds one paragraph announcing the v0.36.0.0 ZE
default with the explicit gbrain config set escape for OpenAI/Voyage
users.

New files:
- docs/INSTALL.md: every install path consolidated (agent platform,
  CLI standalone, MCP server). Thin-client mode covered.
- docs/architecture/RETRIEVAL.md: why the hybrid + graph stack works.
  BrainBench numbers, why each strategy alone fails, the source-aware
  ranking + intent classification + multi-query expansion story.
- docs/ethos/ORIGIN.md: origin story lifted from the old README so
  the front door stays factual + concrete.

test/readme-hero-anchors.test.ts (5 cases) is the D9 regression
guard. Five load-bearing strings: OpenClaw, Hermes, ZE,
production-numbers regex, P@5/R@5. Light anchors that let voice/
structure evolve but block accidental loss of headline facts.

scripts/check-test-real-names.sh: allowlist entries for OpenClaw +
Hermes literals in the anchor test (it explicitly asserts those
strings appear in README).

* chore: bump version and changelog (v0.36.0.0)

ZeroEntropy as the new default for embedding (zembed-1 at 1280d via
Matryoshka) and reranker (zerank-2 cross-encoder, on by default in
balanced mode bundle). README zero-based rewrite (884 -> 139 lines).
3 new docs files. Two new doctor checks. New gbrain ze-switch CLI
with --undo for symmetric reversibility.

skills/migrations/v0.36.0.0.md tells the agent how to surface the
retrieval-upgrade prompt post-upgrade.

llms-full.txt regenerated via bun run build:llms.

* fix(docs): scrub Wintermute from RETRIEVAL.md per privacy rule

* chore: rebump version 0.36.0.0 → 0.36.2.0 (queue collision)

Three open PRs were claiming v0.36.0.0 (#1130 skillpack, #1139
hindsight, #1136 this PR). Ship-aware queue allocator says this
branch lands at v0.36.2.0.

Trio audit:
  VERSION       0.36.2.0
  package.json  0.36.2.0
  CHANGELOG     ## [0.36.2.0] - 2026-05-17

Updates: VERSION, package.json, CHANGELOG header + body refs,
README "New default in v0.36.2.0" announcement + credit line,
skills/migrations/v0.36.0.0.md renamed to v0.36.2.0.md with
frontmatter + body refs updated. llms-full.txt regenerated.

* fix(test): pin gateway dim=1536 in cross-file-stateful PGLite tests

CI shard 1 reported 10 failures across `query-cache.test.ts` (6) and
`consolidate-valid-until.test.ts` (4). Both files hardcode 1536-dim
vectors but rely on `PGLiteEngine.initSchema()` to size
`vector(__EMBEDDING_DIMS__)` at the right width.

Root cause: v0.36.2.0 flipped DEFAULT_EMBEDDING_DIMENSIONS from 1536
to 1280 (ZE Matryoshka step). The gateway module is process-singleton;
when ANOTHER test file in the same shard's bun-test process configures
the gateway before us, `pglite-engine.ts:216` reads
`getEmbeddingDimensions() === 1280` and sizes the schema columns at
vector(1280). The hardcoded 1536-dim INSERTs then fail with
"expected 1280 dimensions, not 1536".

Locally these tests pass in isolation because the gateway falls back
through the try/catch at pglite-engine.ts:218 (1536 default). CI runs
multiple test files in one process, so cross-file state poisons the
schema width.

Fix: explicit `resetGateway()` + `configureGateway({embedding_dimensions:
1536, ...})` at the top of `beforeAll`, plus `resetGateway()` in
`afterAll`. Pins the schema width regardless of cross-file state.

 		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

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

* 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).
