From 80ecaf8eae0387d3e539519978ff0666df076d66 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Thu, 21 May 2026 15:55:37 -0700 Subject: [PATCH 01/12] chore(test): preload gateway to OpenAI/1536 so 1536-dim test fixtures keep working MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The v0.37 fix wave changes the canonical gateway defaults to zeroentropyai:zembed-1 / 1280 (matching what v0.36 already chose as the system default). 20+ test files have hardcoded new Float32Array(1536) fixtures that match the OLD schema default. Without this preload, those tests fail with a vector-dim-mismatch on insert. The preload is gateway-only — it doesn't change which model gbrain ships to production users. Tests that want the new ZE/1280 defaults call configureGateway() explicitly in their own beforeAll.

The gateway shipped zeroentropyai:zembed-1 / 1280 as the system default in v0.36 but eight other places kept hardcoding 1536 / text-embedding-3-large. Fresh gbrain init --pglite sized the column to 1536, the embed pipeline used ZE/1280, and every page failed with dim mismatch. - New src/core/ai/defaults.ts leaf module is the canonical source for DEFAULT_EMBEDDING_MODEL / DEFAULT_EMBEDDING_DIMENSIONS. Schema and registry helpers import from this lean module instead of pulling the full gateway (which loads every provider SDK). - src/core/ai/gateway.ts re-exports the constants for back-compat. - src/core/pglite-schema.ts getPGLiteSchema() defaults track gateway. - src/core/postgres-engine.ts getPostgresSchema() default args track gateway (same drift on the Postgres path — codex round 1 CDX-1). - Both engine.initSchema() fallbacks track gateway constants (no more stale OpenAI/1536 catch-block defaults). - Schema seed stops stripping the provider prefix; full provider:model is stored in the DB config table (codex round 1 CDX-4). - Chunk-row INSERT defaults track gateway (codex round 2 CDX2-4 — pglite-engine:1611 + postgres-engine:1647 were production write sites previously hardcoded to text-embedding-3-large). - src/core/search/embedding-column.ts loadRegistry + isCacheSafe gain the cfg > gateway > DEFAULT resolution chain (codex round 2 CDX2-3). The gateway tier matters because callers that configure the gateway (init paths, tests, programmatic SDK) expect the registry to mirror that state when cfg doesn't have an explicit embedding_model. Tests: - schema-templating: default expectation flips to ZE/1280 (v0.37 truth). - embedding-dim-check: 3 new engine-kind branching cases + updated fresh-brain expectation (under legacy preload). - embedding-column: registry + isCacheSafe expectations match new chain. - v0_28_5-fix-wave E2E: engineKind required arg propagated.

Six related changes that ship together because the file-plane/DB-plane contract only holds when init paths, config-set, the gateway env mapping, and the recipe text all agree. Lane B (init paths): - initPGLite, initPostgres, initMigrateOnly always configureGateway() before engine.initSchema(). Pre-fix the call was gated on flags, so bare `gbrain init --pglite` left the gateway unconfigured and the engine fell through to stale OpenAI/1536 defaults instead of the ZE/1280 the gateway would have resolved. - New configureGatewayWithMergedPrecedence() helper applies the locked precedence chain `CLI > env > existing file > gateway internal`. - printResolvedAIChoice() shows the resolved model/dim at init time + surfaces a ZE setup hint inline when the API key is missing. - B.4: saveConfig merge uses loadConfigFileOnly() so transient env state (DATABASE_URL, etc.) never poisons ~/.gbrain/config.json (codex round 2 CDX-5). - B.5: extend the v0.28.5 dim-mismatch detector so it fires when the gateway-resolved dim differs from the existing column, not only when --embedding-dimensions is explicit (codex round 2 CDX-6). Lane C (config plane): - New `loadConfigFileOnly()` reads ~/.gbrain/config.json only — no env merge, no DATABASE_URL inference. Safe write-back source for init. - GBrainConfig gains `zeroentropy_api_key?: string`. loadConfig merges process.env.ZEROENTROPY_API_KEY. buildGatewayConfig at cli.ts:1401 maps it into env.ZEROENTROPY_API_KEY so ZE recipes finally see it (codex round 2 CDX2-5+6 — the v1 fix landed in the wrong file). - `gbrain config set embedding_model` and `... embedding_dimensions` refuse unconditionally and print a paste-ready wipe-and-reinit recipe. No --force escape (codex round 2 CDX2-13). - migrate-engine.ts adds a contract comment at the DB-plane write site documenting "DB stores schema-applied metadata; file plane is canonical for runtime gateway config" + preserves the existing file-plane config across engine migration. Lane D.1 (recipe text): - embeddingMismatchMessage() takes an `engineKind` arg. PGLite branch emits a wipe-and-reinit recipe using gbrainPath('brain.pglite') or the caller's databasePath override. Postgres branch keeps the SQL ALTER recipe. - The PGLite recipe recommends `gbrain reinit-pglite` (new sugar command below) as the one-line path before falling back to the by-hand mv + init + sync sequence. Lane D.4 (sync help dispatch): - `sync` and `reinit-pglite` added to CLI_ONLY_SELF_HELP so their own --help branches reach the user (pre-fix the generic short-circuit fired first and the dedicated usage was unreachable; codex round 2 CDX2-12). - `gbrain sync --help` short-circuits BEFORE engine bind so users on a fresh tmpdir (no config) can read the help without hitting no-such-config errors. Sugar: - New `gbrain reinit-pglite --embedding-model X --embedding-dimensions N` wraps the wipe + init + sync dance into one command. Backs up the brain to .bak. TTY confirmation unless --yes. --no-sync to defer the resync. --json for scripts. Tests: - test/cli.test.ts sync-help test rewritten for the new per-command-usage output (lists --no-embed which is the v0.37 user-visible flag the wave wanted to surface).

Pre-fix, a fresh-install dim mismatch produced raw Postgres "expected N dimensions, not M" errors page after page, surfacing only after the worker pool drained the entire corpus. Sync swallowed embed errors at TWO catch sites and never surfaced the recovery recipe. embed.ts: - New `EmbeddingDimMismatchError` tagged class with the paste-ready recipe baked in. - `runEmbedCore` pre-flights via `readContentChunksEmbeddingDim` + gateway.getEmbeddingDimensions() before the worker pool spins up. On mismatch, throws the typed error which the CLI wrapper catches and prints. Dry-run skips the check (no embed risk). - Catches the headline fresh-install bug class at first call instead of letting it hammer N parallel API calls into dim-rejected inserts. sync.ts: - Both embed catches at sync.ts:990 (incremental) and sync.ts:1129 (first-sync) detect EmbeddingDimMismatchError and surface the recipe + a `--no-embed` tip on stderr (codex round 2 CDX2-8: incremental path was previously silent; only the first-sync path was flagged). - Non-mismatch embed failures still stay best-effort (rate limits, transient network) — those shouldn't break sync. - Sync calls runEmbedCore directly instead of runEmbed (which calls process.exit on error and bypasses sync's catch). - Sync gets a proper --help block listing every meaningful flag: --no-embed, --workers, --source, --skip-failed, --retry-failed, --watch, --interval, --no-pull, --all, --json, --yes, --dry-run.

Post v0.37 the file plane is canonical (the DB plane is schema-applied metadata, not runtime gateway config) so those reads produced stale verdicts on fresh installs whose DB row hadn't been written. - checkEmbeddingWidthConsistency reads gateway.getEmbeddingDimensions() and gateway.getEmbeddingModel() instead of engine.getConfig(...). Reuses readContentChunksEmbeddingDim from the same shared helper init + embed use. On mismatch, the fix hint threads engineKind + databasePath into the new branched recipe (codex round 1 CDX-8 + Lane E.1/E.2). - checkZeEmbeddingHealth reads gateway for the model + loadConfigFileOnly for the key. Fires when (a) resolved model starts with zeroentropyai: AND (b) ZEROENTROPY_API_KEY is unset in env AND (c) file plane has no zeroentropy_api_key (codex round 2 CDX2-10). - loadRecommendationContext reads gateway for both fields and recognizes the ZE key alongside OpenAI/Anthropic in the hasEmbeddingApiKey check, so brains on ZE no longer look "healthy" just because OPENAI_API_KEY happens to be set (codex round 2 CDX2-11). Tests rewritten for the gateway-source-of-truth contract via configureGateway() in beforeAll. Added a "gateway unconfigured: skips with ok" case so doctor doesn't false-warn on cold-boot brains.

The plan's stricter D.2 (CDX2-9) called for a shared `AbortController` in `embedAll()` so a mid-run mismatch on one worker propagates to the rest of the pool.

The audit found 10+ END-TO-END behaviors that the structural tests didn't actually reach. This file fills the highest-leverage gaps. Unit coverage (test/v0_37_gap_fill.test.ts, 12 cases): - Lane A.7: chunk-row INSERT default tracks DEFAULT_EMBEDDING_MODEL constant (pre-fix this was the literal 'text-embedding-3-large' at pglite-engine.ts:1611 + postgres-engine.ts:1647 — production write sites that were never directly tested; codex round 2 CDX2-4). - Lane A.8: schema seed stores full provider:model in DB config (pre-fix the .split(':') strip dropped the prefix; codex round 1 CDX-4). Asserts a fresh ZE init stores `zeroentropyai:zembed-1` in the config table, not bare `zembed-1`. - Lane B precedence: explicit CLI > env > existing file > default test (codex round 2 CDX2-7 contradiction guard). - Lane C.3 env merge: process.env.ZEROENTROPY_API_KEY threads through loadConfig → cfg.zeroentropy_api_key; loadConfigFileOnly does NOT. - Lane D.2 end-to-end: schema=1536 + gateway=1280 → EmbeddingDimMismatchError fires AND the embed transport is never called (the whole point of pre-flight). Plus dry-run skips the check. - Lane D.3 source-text grep: both sync.ts catch sites detect the typed error + the `--no-embed` tip is present (CDX2-8). - Lane E.4 source-text grep: loadRecommendationContext is provider-aware (reads gateway + branches on ZE/OpenAI key). - reinit-pglite contract: refuses on non-PGLite engines + refuses when required flags are missing. E2E (test/e2e/fresh-install-pglite.test.ts, 2 cases): - Bare `gbrain init --pglite` produces a `vector(1280)` schema, prints the resolved choice, persists defaults to config.json — the headline scenario that v0.37 ships to fix. - init → seed page → embed end-to-end: chunks have non-null embeddings; no dim mismatch despite the wave's defaults change. Both E2E cases are IN-PROCESS (per CDX2-12: CLI-subprocess E2E can't inherit `__setEmbedTransportForTests`). They run with stubbed transport returning synthetic 1280-dim vectors so we never hit real provider APIs.

The default model the gateway shipped (ZeroEntropy at 1280 dimensions) and the default column the schema created (OpenAI's 1536) silently disagreed, and every documented escape hatch was also broken: `gbrain config set embedding_model X` wrote to a database table the embed pipeline doesn't read, the doctor remediation hint pointed at that no-op command, and the docs prescribed `ALTER COLUMN TYPE vector(N)` which fails on PGLite because pgvector ships as embedded WASM. The user spent an hour in source code to figure out you had to hand-edit `~/.gbrain/config.json` after init — completely undocumented. This release closes the bug class end-to-end. + +### How to upgrade + +```bash +gbrain upgrade +# Already on a 1536-d brain that works? You don't have to do anything. +# Starting fresh or wanting to switch models? Use the new one-liner: +gbrain reinit-pglite --embedding-model zeroentropyai:zembed-1 --embedding-dimensions 1280 +``` + +### What's new for everyone + +- **`gbrain init --pglite` produces a vector(1280) schema by default** that matches the embed model the gateway actually uses. Embedding succeeds on the first call. Init prints the resolved choice up front so you see what shipped: `Embedding: zeroentropyai:zembed-1 (1280d) [default]`. +- **`gbrain reinit-pglite --embedding-model X --embedding-dimensions N`** — single-command wipe-and-reinit for switching providers on PGLite. Backs up the brain to `.bak`, runs init with the new flags, re-syncs the brain repo. `--no-sync` to defer the resync, `--yes` to skip the TTY confirmation, `--json` for scripts. +- **`gbrain init` re-run no longer destroys your settings.** Existing `~/.gbrain/config.json` fields are merged on top of new init flags, so re-running with no args preserves `embedding_model`, `chat_model`, API keys, and every other field you set. +- **`gbrain sync --help` actually documents `--no-embed` now.** The flag has existed for releases but was unreachable through `--help` because sync wasn't wired into the dispatcher's self-help set. +- **`gbrain config set embedding_model X` refuses with the right recipe.** That command wrote to the DB plane while the embed pipeline read the file plane, so it silently lied for releases. It now exits 1 with a paste-ready wipe-and-reinit recipe pointing at the engine you're actually running on (`gbrain reinit-pglite` on PGLite, the `ALTER COLUMN` SQL recipe on Postgres). No `--force` escape — keeping the no-op write path was the original footgun. +- **ZeroEntropy API key plumbing works.** Before this release the embed pipeline only mapped `OPENAI_API_KEY` and `ANTHROPIC_API_KEY` from your config into the gateway env, so `zeroentropy_api_key` in `~/.gbrain/config.json` was dead config. Now it propagates correctly. `ZEROENTROPY_API_KEY` env var also routes through. +- **`gbrain embed --stale` fails fast with a paste-ready recipe** when the schema column and the gateway disagree. Pre-fix the worker pool would fire 20 parallel API calls into dim-rejected inserts and surface only the raw Postgres error. Now you see the wipe-and-reinit recipe before any embed call goes out. +- **`gbrain sync` surfaces the recipe + `--no-embed` tip** when its inline embed step hits a dim mismatch. Previously the sync step silently swallowed embed errors at two different catch sites. Both sites now print the recipe. +- **`gbrain doctor` reads the embed checks from the gateway, not the DB plane.** The width-consistency and ZE-key checks were stale on fresh installs whose DB rows hadn't been written yet. They now see what the embed pipeline sees. Provider-aware key detection too: a ZE brain no longer looks "healthy" because `OPENAI_API_KEY` happens to be set. + +### What's new for contributors + +- **New `src/core/ai/defaults.ts` leaf module** is the canonical source for `DEFAULT_EMBEDDING_MODEL` and `DEFAULT_EMBEDDING_DIMENSIONS`. Eight other places used to hardcode `'text-embedding-3-large'` / `1536` independently — those are all migrated to import from defaults.ts. Changing the default in one place now propagates correctly. Includes the PGLite + Postgres engine fallbacks, both `getPGLiteSchema()` / `getPostgresSchema()` default args, the embedding-column registry's builtin row, the chunk-row INSERT default, and the schema seed (which previously stripped the provider prefix and stored bare `zembed-1` instead of `zeroentropyai:zembed-1`). +- **New `loadConfigFileOnly()` in `src/core/config.ts`** is the safe write-back source for `gbrain init` 's config merge. Pre-fix init called `loadConfig()` (which merges env vars + infers engine from `DATABASE_URL`) to read existing config before saving — so any transient env value would get baked into `~/.gbrain/config.json`. The new helper reads the JSON file only. +- **`embeddingMismatchMessage()` takes an `engineKind` argument now.** PGLite branch emits the new `gbrain reinit-pglite` recipe; Postgres branch keeps the SQL ALTER. The `databasePath` arg lets the recipe use the brain's actual path instead of `~/.gbrain/brain.pglite` (honors `GBRAIN_HOME`, `--path` overrides). +- **`EmbeddingDimMismatchError` is a tagged class exported from `src/commands/embed.ts`.** `runEmbedCore` pre-flights via the existing `readContentChunksEmbeddingDim` helper and throws this error before the worker pool starts. Sync catches it specifically for the recipe + `--no-embed` tip. +- **CDX2-5+6 from codex review:** the ZE key fix v1 landed in the wrong file (`gateway.ts:configureGateway` instead of `cli.ts:buildGatewayConfig`). Round 2 caught + fixed it. Pinning regression at `test/v0_37_fix_wave.test.ts`'s Lane C.3 describe. +- **30+ unit tests + 1 in-process E2E** cover every lane. Highlights: `test/v0_37_fix_wave.test.ts` (structural lane assertions), `test/v0_37_gap_fill.test.ts` (end-to-end behavior + reinit-pglite contracts), `test/e2e/fresh-install-pglite.test.ts` (headline scenario via `__setEmbedTransportForTests` mock). The legacy `test/embedding-dim-check.test.ts` and `test/doctor-ze-checks.test.ts` and `test/search/embedding-column.test.ts` are also updated for the new behaviors. +- **`bunfig.toml` preload** at `test/helpers/legacy-embedding-preload.ts` configures the gateway to OpenAI/1536 once per shard process, so the 20+ test files that hardcode `new Float32Array(1536)` fixtures keep working without per-file edits. +- 26 codex outside-voice findings across two review rounds folded into the plan before code landed. Plan file: `~/.claude/plans/system-instruction-you-are-working-piped-mitten.md`. + +### Deferred to follow-up + +Filed in TODOS.md: +- `gbrain embed --try-fallback` for provider quota/auth failures (silent provider switching would corrupt retrieval; needs explicit consent design). +- Full plane unification for non-schema-sizing fields (`chat_model`, `expansion_model`, `reranker_model` could become DB-live-mutable — audit pending). +- Worker-pool shared `AbortController` in `embedAll()` as defense-in-depth on top of the entry-point pre-flight. +- Cleanup of back-compat constants in `src/core/embedding.ts` (legacy `EMBEDDING_MODEL` / `EMBEDDING_DIMENSIONS` exports for old tests). + +### To take advantage of v0.37.10.0 + +`gbrain upgrade` should do this automatically.

On a real-corpus benchmark vs OpenAI and Voyage: **2.2× faster** (442ms vs OpenAI 973ms), **2.6× cheaper at regular pricing** ($0.05/M vs OpenAI $0.13), wins 11 of 20 queries head-to-head, reshuffles 60% of top-1 results when used as a second-pass reranker. Bring your own key from [zeroentropy.dev](https://dashboard.zeroentropy.dev), or switch to OpenAI/Voyage at install time via `gbrain init --pglite --embedding-model --embedding-dimensions ` — your choice is sticky. To switch an existing brain, run `gbrain reinit-pglite --embedding-model --embedding-dimensions ` (PGLite) or follow the SQL recipe in `docs/embedding-migrations.md` (Postgres). `gbrain config set embedding_model` is refused as of v0.37.10.0 because the schema column has to resize too. +**New default in v0.36.2.0: ZeroEntropy** for both embedding (`zembed-1` at 1280d via Matryoshka) and reranker (`zerank-2`).

Per the documented quarantine pattern in CLAUDE.md, rename to `*.serial.test.ts` instead of refactoring through `withEnv()` — both files use beforeEach/afterEach env wiring that's already serial-safe.
