From 6a3f24c7850bb7b1b854310ad2f292a888e6053c Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Thu, 21 May 2026 11:28:24 -0700 Subject: [PATCH 01/17] feat(brainstorm): T1 cost guardrails + judge chunking + far-set cap Ports PR #1234 with a typed-error swap (Q2). Brings: - `--max-cost`, `--max-far-set`, `--strict-budget`, `--judge-model`, `--max-ideas-per-judge-call` CLI flags on `gbrain brainstorm` / `lsd` - Domain-bank prefix-cap + shuffle + final-trim to `m` by distance score - Judge auto-chunks idea sets > 100 across multiple LLM calls - UTF-16 surrogate sanitization on cross prompts - Phase-0.5 hard cost ceiling + mid-run cost guard Phase-1 diff from PR #1234: per-cross error-rethrow uses inline typed `BudgetExhausted` instead of string-match on the error message. Phase 2 of the wave will move the class to `src/core/budget/budget-tracker.ts` and the orchestrator will import it. Postmortem doc + 12-case regression test included verbatim from #1234. T1 of the brainstorm cost cathedral plan (~/.claude/plans/system-instruction-you-are-working-rippling-moth.md).

One class, one typed error, one schema-stable audit JSONL. Replaces three parallel copies (brainstorm orchestrator inline class, cycle/budget-meter, eval-contradictions cost-prompt/tracker) — those adapt to this one in T5/T6. Contracts pinned by 26 unit tests: - TX1: record() throws BudgetExhausted(reason:'cost') when cumulative spend > cap. A single underestimated call cannot leak past the cap. - TX2: reserve() hard-fails with BudgetExhausted(reason:'no_pricing') when cap is set + model is missing from pricing maps. When cap is unset, legacy warn-once behavior is preserved. - A3 amended: extractUsageFromError(err, fallback) returns err.usage when SDK provides it, else the pessimistic fallback (caller passes maxOutputTokens, not the optimistic pre-call estimate). - onExhausted callback fires once, synchronously, before the throw propagates. Callbacks do sync I/O (writeFileSync) for checkpoint persistence. - Audit JSONL is schema-stable: every line carries schema_version=1. Reorderings tolerated, field renames are breaking. Also ships src/core/audit-week-file.ts — the shared ISO-week filename helper consumed by every audit writer in T4. Year-boundary correctness pinned by 5 cases including 2020-W53 (the 53-week year), 2025-W01 rolling in from 2024-12-30 (Monday), and the GBRAIN_AUDIT_DIR override.

No per-call injection seam, no flag plumbing — callers wrap their entrypoint in `withBudgetTracker(tracker, async () => { ... })` and every downstream LLM call honors the cap. Outside any scope, the gateway is a budget no-op (back-compat with the pre-v0.37 contract). Wiring: - chat(): reserves on entry using prompt-char heuristic + opts.maxTokens. Records actual usage from result.usage on success; on failure, charges the pessimistic A3-amended fallback so the cap is real. - embed(): reserves total estimated input tokens (chars / chars-per-token). Records the same total in try/finally; SDK doesn't surface per-batch embed token counts. - rerank(): reserves and records query + docs char count. Reranker pricing isn't in the canonical map yet, so reserve() takes the warn-once path under no-cap and the TX2 hard-fail under cap. 6 unit cases pin the contract: chat auto-composes, outside-scope is no-op, nested scope restores outer, over-cap reserve throws BEFORE provider call (proves circuit breaker), TX1 mid-run cumulative cap fires via record(), parallel Promise.all scopes do not bleed trackers. All 255 existing gateway tests and 50 brainstorm tests still pass.

Sites migrated: - src/core/minions/handlers/shell-audit.ts (shell-jobs-YYYY-Www.jsonl) - src/core/facts/phantom-audit.ts (phantoms-YYYY-Www.jsonl) - src/core/audit-slug-fallback.ts (slug-fallback-YYYY-Www.jsonl) - src/core/cycle/budget-meter.ts (dream-budget-YYYY-Www.jsonl) Each call site had its own copy of the ISO-week-from-Date algorithm. They mostly agreed but subtle drift was already accumulating (one used local time, one approximated the Thursday-anchor formula, etc.). One helper, one set of regression tests, no drift. Compute helpers (computeAuditFilename, computePhantomAuditFilename, computeSlugFallbackAuditFilename) are preserved as thin wrappers so existing import sites and tests don't break. All audit + slug-fallback + phantom + budget-meter tests still pass.

The runRemediate loop now runs inside `withBudgetTracker(tracker, ...)` so every gateway-routed LLM call inside a Minion handler (synthesize, patterns, consolidate, embed) honors the cap. When BudgetExhausted fires mid-run, the onExhausted callback persists a checkpoint of completed step ids + idempotency_keys to ~/.gbrain/remediation/.json BEFORE the throw propagates, and the catch surfaces a paste-ready --resume hint. Wire-up: - New --resume flag (with implicit "most recent matching" when no hash given) loads the checkpoint and skips already- completed steps. Mismatched plan_hash refuses with an explicit message. - --max-cost is now an alias for --max-usd. Both spellings honored and threaded through to BudgetTracker.maxCostUsd so the cap is a real ceiling, not just pre-flight advice. - On BudgetExhausted, exit 1 with the resume hint; on clean completion, clear the checkpoint.

A BudgetExhausted throw must NOT consume a rate-lease slot, because the lease is the rate-limit pacer for the entire fleet. The handler body intentionally does NOT explicitly thread BudgetTracker; TX5 (gateway-layer composition) handles that. The comment is the reader's signpost. No behavioral change.

Two strategies: - 'batch': deterministic token-budgeted chunking. No LLM calls. The fitted list shape matches the input; the caller decides how to consume it (e.g. brainstorm judge concatenates per-chunk results). Surfaces a `dropped` count for items that exceed the per-call cap. - 'summarize': embed-cluster into ceil(items/4) groups via cheap deterministic nearest-neighbor on cosine; Haiku-summarize each cluster via Promise.allSettled at parallelism=4 (Perf1). Each Haiku call composes the active BudgetTracker via the gateway's AsyncLocalStorage scope (T3) — no per-call injection. Quality gate (codex outside-voice finding #4): when summarize's success_ratio < min_success_ratio (default 0.75), the result is flagged `degraded: true` so the caller (brainstorm) can decide to surface a partial result or abort. The fitter itself preserves the successful subset either way. Tested via 4 cases across two files (T3 contract): - happy path (all clusters succeed → degraded=false) - partial failure tolerated (1/5 fails, success_ratio=0.8 > 0.75 → degraded=false) - high-failure rate flips the gate (3/5 fails → degraded=true) - budget-respecting (BudgetExhausted thrown mid-cluster propagates via Promise.allSettled) 11 unit cases across batch + summarize. Brainstorm + cost-guardrails tests still green; judges.ts internal chunking deferred to a follow-up wave (TODOS) so the existing chunked-batch contract stays byte-stable during this drop.

Crashed runs can resume cleanly via `gbrain brainstorm --resume ` (and `gbrain lsd --resume` etc). TX3 load-bearing contract: completed_crosses on disk carries FULL idea bodies (~50KB per run), not just counts. The resumed BrainstormResult contains the pre-crash ideas (loaded from disk) merged with the post- resume ideas — codex's outside-voice finding was that a resume that produces only "what we generated this run" is silent partial output. TX4 single rule: --resume continues any cross not in completed_crosses. The proposed --retry-failed was dropped per codex review; failed AND never-attempted crosses both go through --resume. A5 amended: run_id = sha256(question + profile + sort(close_slugs) + sort(far_slugs)).slice(0,16). NO embedding bits — stable across embedding-model swaps. 7-day mtime-based GC. Q2 fold: orchestrator.ts drops its inline BudgetExhausted class and re-exports the canonical one from src/core/budget/budget-tracker.ts (Phase 2). runBrainstorm now wraps the body in withBudgetTracker so every gateway-layer chat call auto-records cost. The cap remains opts.maxCostUsd (default $5). New CLI flags: --resume Continue any cross not in completed_crosses. Refuses to start when run_id doesn't match the active inputs (paste-ready hint). --force-resume Bypass the 7-day staleness gate. --list-runs Print saved run_ids and exit. Cycle purge phase (the 9th cycle phase) now also GCs stale brainstorm checkpoints alongside op_checkpoints (~7d window). Tests: - 20 unit cases in test/brainstorm/checkpoint.test.ts: computeRunId is deterministic + slug-array-order invariant + stable across embedding-model swaps; round-trip preserves ideas verbatim; saveCheckpoint atomic via .tmp+rename; loadCheckpoint returns null on missing/schema-mismatch/corrupt-JSON; gcStaleCheckpoints unlinks >N days; listRuns mtime-ordered. - 3 E2E cases in test/e2e/brainstorm-resume.test.ts: crash on cross 4 → first run aborts with checkpoint of crosses 1..N with full idea bodies; second run with resumeRunId merges pre-crash + post-resume ideas (TX3 contract); mismatched run_id refuses with paste-ready hint. The PGLite schema-gap workaround in the E2E (CREATE VIEW page_links AS SELECT * FROM links) is filed as a follow-up in TODOS T12 — the real-engine brainstorm path needs that view to materialize as a canonical schema fix.

A `gbrain lsd` run estimated $0.96, actually billed $50.71, generated zero usable ideas. The fix wave already merged (PR #1234) capped the prefix sampling that caused the explosion. This release goes one cathedral further: every LLM call that any `gbrain` command makes is now accounted at the gateway layer, so the same cap that protects brainstorm also protects `doctor --remediate`, `eval suspected-contradictions`, the dream cycle, and any future LLM-calling command. The plumbing is shared. + +What that means in the hand: pass `--max-cost N` to brainstorm or lsd or `doctor --remediate`, and the first overflow throws a typed error before any extra dollars are spent. The throw fires from inside the gateway's reserve check, so a budget exhaustion never even acquires a rate-lease slot or makes a provider HTTP call. The cap is a real ceiling, not a suggestion. + +When brainstorm IS exhausted mid-run, the orchestrator persists what's been done to `~/.gbrain/brainstorm/.json` with the FULL idea bodies (not just counts), then re-throws. The user paste-runs the suggested `gbrain brainstorm --resume ` and the second run skips the already-completed crosses, runs only the missing ones, then merges everything before the judge runs. The final BrainstormResult contains the pre-crash ideas AND the post-resume ideas. (Codex's outside-voice review was the one that caught this — a resume that produces only the second-run's ideas would be silent partial output, which is worse than no resume at all.) + +### How to turn it on + +```bash +# Cap brainstorm cost at $2 (default $5).

If you cron-schedule `--remediate`, the worst case used to be "the run starts despite the under-estimate"; now the worst case is "the run aborts mid-step and writes a resumable checkpoint." The first failure-mode is gone; the second is recoverable via `--resume`. `--max-cost` is a new alias for `--max-usd` for symmetry with brainstorm. + +The brainstorm checkpoint identity intentionally uses NO embedding bits: `run_id = sha256(question + profile + sort(close_slugs) + sort(far_slugs)).slice(0,16)`. Swap your embedding model between runs and the resume still finds the checkpoint. Conversely, change the question by even one word and you get a different run_id (the previous checkpoint is left alone; the cycle purge phase GCs anything older than 7 days). + +The dream cycle's `~/.gbrain/audit/dream-budget-YYYY-Www.jsonl` grew one new field on every line: `schema_version: 1`. Reorderings are tolerated (downstream consumers should index by field name, not position); renames or removals are breaking. The same schema-stable contract holds for the new `~/.gbrain/audit/budget-YYYY-Www.jsonl` produced by the unified `BudgetTracker`. + +If you wrote integration code against `BudgetExhausted` in the brainstorm orchestrator before this release: that class moved to `src/core/budget/budget-tracker.ts`. The orchestrator re-exports the old name for back-compat, so existing imports keep working. + +### Itemized changes + +- **`BudgetTracker` is the new canonical primitive** at `src/core/budget/budget-tracker.ts`. One class, one typed error (`BudgetExhausted` with `reason: 'cost' | 'runtime' | 'no_pricing'`), one schema-stable audit JSONL. Pinned by 18 unit cases covering TX1 (record throws when cumulative exceeds cap), TX2 (no_pricing hard-fails when cap is set + pricing missing), A3 amended (pessimistic fallback when `err.usage` is absent), the onExhausted-fires-once-before-throw contract, and the schema-stable audit schema. +- **`withBudgetTracker(tracker, fn)` at the gateway layer (TX5)** installs the tracker on a module-internal `AsyncLocalStorage`. Every `gateway.chat / embed / rerank` call inside the scope auto-composes. Outside-scope calls are budget no-ops (existing behavior preserved). Nested scopes restore the outer on exit. Parallel `Promise.all` scopes do not bleed trackers across each other. +- **Subagent rate-lease ordering pinned (A1)**: the gateway's `reserve()` runs BEFORE `acquireLease()` in `src/core/minions/handlers/subagent.ts`. A budget throw must NOT consume a rate-lease slot. The handler body itself no longer needs explicit budget threading; the AsyncLocalStorage composition handles it. +- **`payload-fitter.ts` (P6)** lands at `src/core/diarize/payload-fitter.ts` with two strategies. `'batch'` is deterministic token-budgeted chunking, no LLM calls. `'summarize'` embed-clusters then Haiku-summarizes each cluster in parallel via `Promise.allSettled` at parallelism=4. The quality gate flags `degraded: true` when success ratio drops below the configured `min_success_ratio` (default 0.75) — caller decides whether to surface or abort. +- **Brainstorm checkpoint (P7)** at `src/core/brainstorm/checkpoint.ts`. Atomic .tmp+rename writes. Full idea bodies persisted (TX3). One-flag resume (TX4). 7-day mtime-based GC wired into the cycle purge phase. +- **`doctor --remediate --resume`** loads `~/.gbrain/remediation/.json` and continues from the next un-completed step. Refuses on mismatched plan_hash with a paste-ready message. +- **`gbrain brainstorm --list-runs`** prints saved run_ids + iso dates + question stems so the user can pick which to resume. +- **ISO-week audit filenames consolidated** into `src/core/audit-week-file.ts`. Four call sites migrated (shell-jobs, phantoms, slug-fallback, dream-budget). Year-boundary cases (2020-W53, 2024-12-30 belongs to 2025-W01) pinned by tests. +- **eval-contradictions** routes through `withBudgetTracker` for telemetry without changing the CLI surface. `--budget-usd` semantics + `PreFlightBudgetError` shape are byte-identical. + +### For contributors + +- `bun test` adds 73 new tests across 9 new files (`test/core/budget/`, `test/core/audit-week-file.test.ts`, `test/core/diarize/`, `test/brainstorm/checkpoint.test.ts`, `test/e2e/brainstorm-resume.test.ts`, `test/core/remediation-checkpoint.test.ts`). All previous brainstorm + doctor + eval-contradictions tests still pass. +- The `test/e2e/brainstorm-resume.test.ts` works around a pre-existing PGLite schema gap (the brainstorm domain-bank queries `page_links` but the embedded schema only defines `links`) by creating a view inside the test setup. Filed as a follow-up in `TODOS.md` — the canonical schema needs the view materialized so `gbrain brainstorm` works against PGLite brains in production. + ## [0.37.9.0] - 2026-05-20 **Tags get written the same way everywhere now.** diff --git a/CLAUDE.md b/CLAUDE.md index 67195c736..49f7530c4 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -108,6 +108,12 @@ strict behavior when unset. - `src/core/ai/recipes/voyage.ts` — Voyage AI openai-compatible recipe. **v0.28.7 (#680):** declares `chars_per_token=1` + `safety_factor=0.5` so the gateway pre-splits Voyage batches at a 60K-character budget (50% of 120K-token cap with the dense-tokenizer ratio).

The "all v4 variants are flexible" misread is what caused the original PR to include nano in `VOYAGE_OUTPUT_DIMENSION_MODELS`; the negative regression assertion in `test/ai/gateway.test.ts` (`dimsProviderOptions` returns `undefined` for `voyage-4-nano`) pins the contract. **v0.37.3.0:** `voyage-code-3` is the recommended embedding model for gstack per-worktree code brains (Topology 3 in `docs/architecture/topologies.md`). Registration was already in the `models` list since pre-v0.33; the v0.37.3.0 wave adds discoverability surfaces — decision-tree branch in `docs/integrations/embedding-providers.md`, Topology 3 "Recommended embedding model" subsection, runtime nudge from `gbrain reindex --code` against non-code-tuned models. Recipe-shape regression pinned by `test/ai/voyage-code-3-recipe.test.ts`. - `src/core/ai/recipes/anthropic.ts` — Anthropic recipe (chat + expansion touchpoints). **v0.31.12:** chat and expansion `models:` lists drop the v0.31.6 phantom `claude-sonnet-4-6-20250929` date suffix — canonical id is `claude-sonnet-4-6`. The wrong-direction alias `claude-sonnet-4-6 → claude-sonnet-4-6-20250929` is removed; a reverse alias `claude-sonnet-4-6-20250929 → claude-sonnet-4-6` keeps stale user configs working (rescues `facts.extraction_model` and `models.dream.synthesize` set by v0.31.6 installs). Recipe-shape regression pinned by `test/anthropic-model-ids.test.ts` (6 cases, verbatim cherry-pick of PR #830 plus the reverse-alias rescue case). - `src/core/anthropic-pricing.ts` — Single source of truth for Anthropic model pricing (per-MTok input/output). **v0.31.12:** Opus 4.7 corrected from `$15/$75` to `$5/$25` (the old number was from Opus 4 generation, never refreshed when 4.7 shipped); Opus 4.6 also corrected. Consumed by `src/core/budget-meter.ts` and `src/core/cross-modal-eval/runner.ts` — the cross-modal estimator now reads `ANTHROPIC_PRICING` for Anthropic models instead of duplicating the table, killing the v0.31.6 drift bug class. +- `src/core/budget/budget-tracker.ts` (v0.37.x) — keystone primitive for the brainstorm cost-cathedral wave. One typed error (`BudgetExhausted` with `reason: 'cost' | 'runtime' | 'no_pricing'`), one schema-stable audit JSONL at `~/.gbrain/audit/budget-YYYY-Www.jsonl`. Contracts pinned by 18 unit cases: **TX1** — `record()` throws when cumulative spend exceeds cap (the cap is a real ceiling, not a suggestion); **TX2** — `reserve()` hard-fails with `reason: 'no_pricing'` when `maxCostUsd` is set AND the model is missing from pricing maps (warn-once preserved when cap is unset); **A3 amended** — `extractUsageFromError(err, fallback)` returns `err.usage` when SDK provides it, else the pessimistic fallback (caller passes `maxOutputTokens`, not the optimistic pre-call estimate). `onExhausted(cb)` callback fires once synchronously BEFORE the throw propagates so callers can persist checkpoints. Replaces three parallel copies (inline brainstorm class, cycle/budget-meter, eval-contradictions). Adapts the old `BudgetMeter` via T5 (public shape preserved + `schema_version: 1` stamped on every dream-budget audit line). +- `src/core/audit-week-file.ts` (v0.37.x, Q1) — single source of truth for ISO-week audit JSONL filename math. Exports `isoWeek(d)`, `isoWeekFilename(prefix, now?)`, `resolveAuditDir()` (honors `GBRAIN_AUDIT_DIR`). Year-boundary correctness pinned by tests at 2020-W53 (the 53-week year), 2025-W01 rolling in from 2024-12-30 (Monday), 2026-W01. Four call sites migrated in T4: `src/core/minions/handlers/shell-audit.ts`, `src/core/facts/phantom-audit.ts`, `src/core/audit-slug-fallback.ts`, `src/core/cycle/budget-meter.ts`. Each call site keeps its `computeAuditFilename` thin wrapper for back-compat with existing tests. +- `src/core/ai/gateway.ts:withBudgetTracker` (v0.37.x, T3 / TX5) — gateway-layer enforcement via `AsyncLocalStorage`. `withBudgetTracker(tracker, fn)` installs the tracker on the module-internal store; every `gateway.chat / embed / rerank` call inside the scope auto-composes (reserve before, record in try/finally). Outside-scope calls are budget no-ops (current behavior preserved). Nested scopes restore the outer tracker on exit. `getCurrentBudgetTracker()` is the test seam. The chat path uses A3-amended pessimistic fallback on error paths; the embed path estimates input tokens from char count × recipe's `chars_per_token` because the AI SDK doesn't surface per-batch embed token usage; the rerank path estimates char count of query+docs. 6 unit cases pin the contract. +- `src/core/diarize/payload-fitter.ts` (v0.37.x, P6 / Q3) — generic fit-arbitrarily-large-items-into-per-call-token-budget utility. `'batch'` strategy is deterministic token-budgeted chunking with no LLM calls. `'summarize'` strategy embed-clusters into ceil(items/4) groups via cheap deterministic nearest-neighbor on cosine, Haiku-summarizes each cluster via `Promise.allSettled` at parallelism=4 (Perf1). Each Haiku call composes the active BudgetTracker via T3's AsyncLocalStorage. The quality gate (codex outside-voice finding #4): when `success_ratio < min_success_ratio` (default 0.75), result is flagged `degraded: true` — the fitter preserves the successful subset; the caller decides whether to surface a partial result or abort. +- `src/core/brainstorm/checkpoint.ts` (v0.37.x, P7 / TX3+TX4+A5 amended) — crash-resilient checkpoint for `gbrain brainstorm` and `gbrain lsd`. Persists FULL idea bodies (~50KB per run) so resume can MERGE the pre-crash ideas with the post-resume ideas before the judge runs (codex's load-bearing finding — a resume that produces only second-run output is silent partial output). `run_id = sha256(question + profile + sort(close_slugs) + sort(far_slugs)).slice(0,16)` — NO embedding bits, stable across embedding-model swaps. Atomic write via `.tmp + rename`. ONE resume flag (`--resume ` — the proposed `--retry-failed` was dropped per TX4: failed AND never-attempted crosses both go through `--resume`). `--list-runs` prints saved run_ids mtime-newest-first. `--force-resume` bypasses the 7-day staleness gate. The cycle purge phase (`gbrain dream --phase purge`) GCs checkpoints older than 7 days via `gcStaleCheckpoints(7)`. Pinned by 20 unit cases + 3 E2E cases in `test/e2e/brainstorm-resume.test.ts` including the load-bearing merge contract. +- `src/core/remediation-checkpoint.ts` (v0.37.x, T7 / A4 amended) — `doctor --remediate` checkpoint at `~/.gbrain/remediation/.json`. `plan_hash = sha256(JSON.stringify(sorted recommendation ids)).slice(0,16)`. Schema-versioned. Atomic write via `.tmp + rename`. `gbrain doctor --remediate --resume ` (or with no arg — picks the newest matching checkpoint) loads it and skips already-completed steps. Mismatched plan_hash refuses with a paste-ready message. Cleared on clean completion. Pinned by 13 unit cases. - `src/core/model-config.ts` — Model-string resolution (the seam every internal LLM call walks through). **v0.31.12:** four-tier system (`ModelTier = 'utility' | 'reasoning' | 'deep' | 'subagent'`) with `TIER_DEFAULTS` (utility→haiku-4-5, reasoning→sonnet-4-6, deep→opus-4-7, subagent→sonnet-4-6) and `tier?: ModelTier` on `ResolveModelOpts`. Resolution chain is now 8 steps: cliFlag → deprecated key → config key → `models.default` → `models.tier.` → env var → `TIER_DEFAULTS[tier]` → caller fallback. Two new exports — `isAnthropicProvider(modelString)` checks `provider:model` prefix OR `claude-` bare-id pattern, and `enforceSubagentAnthropic()` is the layer-2 runtime guard: when `tier === 'subagent'` resolves to a non-Anthropic provider, it emits a once-per-`(source, model)` stderr warn AND falls back to `TIER_DEFAULTS.subagent` instead of letting the Anthropic Messages API tool-loop attempt to run on OpenAI/Gemini. `_resetDeprecationWarningsForTest()` now also clears `_subagentTierWarningsEmitted` so tests re-emit. - `src/core/ai/model-resolver.ts` — Recipe-touchpoint validator. **v0.31.12:** `assertTouchpoint(recipe, touchpoint, modelId, extendedModels?)` gains an optional 4th `extendedModels: ReadonlySet` argument. When the modelId is in that set, the native-recipe allowlist throw is bypassed — the user explicitly opted into this model via config so we let provider rejection surface as `model_not_found` at HTTP call time (and `gbrain models doctor` catches it earlier). Default code paths with hardcoded model strings MUST NOT pass `extendedModels` — typos in source code still fail fast. Replaces the earlier plan to soften the validator wholesale (Codex F4/F5 in plan review flagged that as too broad — it would have removed the fail-fast contract for chat + expand + embed all three). - `src/core/ai/gateway.ts` extension (v0.31.12) — new module-scoped `_extendedModels: Map>` registry feeds `assertTouchpoint`'s 4th-arg path. New `reconfigureGatewayWithEngine(engine)` async function is called from `cli.ts` after `engine.connect()` (and before every command except `CLI_ONLY` no-DB commands) — re-resolves expansion + chat defaults through `resolveModel()` so `models.tier.*` and `models.default` overrides apply to expansion + chat both. `DEFAULT_CHAT_MODEL` corrected to `anthropic:claude-sonnet-4-6` (was the v0.31.6 phantom `-20250929`). New `__setChatTransportForTests` seam mirrors `__setEmbedTransportForTests` so tests drive `chat()` with a stubbed transport. diff --git a/TODOS.md b/TODOS.md index 18898ccc8..6203add45 100644 --- a/TODOS.md +++ b/TODOS.md @@ -1,6 +1,33 @@ # TODOS +## v0.37.x brainstorm cost-cathedral follow-ups (filed during T12) + +- [ ] **PGLite schema fix for `page_links`.** The brainstorm domain-bank queries reference `page_links` (`src/core/pglite-engine.ts:896`, `:984`) but the embedded `src/core/pglite-schema.ts` only defines `links`. As a result, `gbrain brainstorm` against a PGLite brain fails with `relation "page_links" does not exist`. The v0.37.x E2E (`test/e2e/brainstorm-resume.test.ts`) works around this by creating `CREATE OR REPLACE VIEW page_links AS SELECT * FROM links` inside the test setup.

When the modelId is in that set, the native-recipe allowlist throw is bypassed — the user explicitly opted into this model via config so we let provider rejection surface as `model_not_found` at HTTP call time (and `gbrain models doctor` catches it earlier). Default code paths with hardcoded model strings MUST NOT pass `extendedModels` — typos in source code still fail fast. Replaces the earlier plan to soften the validator wholesale (Codex F4/F5 in plan review flagged that as too broad — it would have removed the fail-fast contract for chat + expand + embed all three). - `src/core/ai/gateway.ts` extension (v0.31.12) — new module-scoped `_extendedModels: Map>` registry feeds `assertTouchpoint`'s 4th-arg path.

When the caller passes --max-cost N (or --max-cost-usd N), runReindexCode wraps its per-page import loop in withBudgetTracker so every gateway.embed() call inside importCodeFile auto-composes the cap. On BudgetExhausted, the partial-progress result reports what got reindexed before the cap fired plus a synthetic failure row naming the cap throw. reindex-code is idempotent (content_hash short-circuit in importCodeFile), so a re-run after a budget abort picks up where the cap fired — no manual checkpoint state needed. Both --max-cost and --max-cost-usd are accepted (symmetry with brainstorm which uses --max-cost, and a precedent for the spelling we want long-term). When --max-cost is unset, the body runs outside any tracker scope — byte- stable pre-F3 behavior for legacy callers.
