From 934d7ea4b69e32b80f60c0d6b7c5b981c58d52c3 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Mon, 20 Apr 2026 21:46:55 +0800 Subject: [PATCH] =?UTF-8?q?feat(eval):=20Day=204=20=E2=80=94=20pdf-parse?= =?UTF-8?q?=20+=20flight-recorder=20+=20tool-bridge=20(dry=5Frun=20+=20exp?= =?UTF-8?q?and:false)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three infrastructure modules for BrainBench v1 Complete Cats 5/8/9/11. **eval/runner/loaders/pdf.ts** — Thin pdf-parse wrapper. Lazy import keeps pdf-parse out of the module-load path (avoids library debug-mode side effects). Size cap (50MB default), encryption detection, structured error classes (PdfEncryptedError, PdfTooLargeError, PdfParseError). Only Cat 11 multimodal will import this; production bundle never sees pdf-parse. **eval/runner/tool-bridge.ts** — Maps 12 read-only operations from src/core/operations.ts to Anthropic tool definitions + adds 3 dry_run write tools. Three structural invariants enforced: 1. No hidden LLM calls. `operations.query` defaults expand=true which routes through expansion.ts → Haiku. Bridge strips `expand` from the query tool's input schema AND executor hard-sets expand:false. Zero nested Haiku calls in any agent trace. 2. Mutating ops throw ForbiddenOpError. put_page, add_link, delete_page, etc. are rejected by name. Agents record intent via dry_run_put_page / dry_run_add_link / dry_run_add_timeline_entry which persist to the flight-recorder without mutating the engine. This is how Cat 8's back_link_compliance + citation_format metrics measure anything with a read-only tool surface. 3. Poison tagged by the bridge, not the judge. Every tool result is scanned for slugs matching gold/poison.json fixtures. Matched fixture_ids flow into tool_call_summary.saw_poison_items for the structured-evidence judge contract. Judge never reads raw tool output — Section-3 defense against paraphrased prompt injections (poison payloads never reach the judge model at all). 32K-token cap (~128K chars) with "…[truncated]" suffix. **eval/runner/recorder.ts** — Per-run flight-recorder bundle emitter. Full 6-artifact bundle (transcript.md, brain-export.json, entity-graph.json, citations.json, scorecard.json, judge-notes.md) when the adapter provides an AdapterExport; 3-artifact fallback (transcript + scorecard + judge-notes) otherwise. Atomic writes via tmp+rename. Collision-safe: duplicate directory names get incremental -2, -3 suffix. `safeStringify` handles circular references without throwing and JSON-serializes Float32Array embeddings. **package.json:** adds pdf-parse@2.4.5 as a devDependency. Scoped to eval/ use only; production gbrain binary unaffected. **Tests:** 63 new — 30 tool-bridge, 21 recorder, 12 pdf-loader. All pass. Fake engine uses a Proxy with `__default__` fallback so poison-matching tests don't have to mock the exact engine method name that each operation calls (some route via searchKeyword, others via getPage — proxy handles both uniformly). Total eval suite now: 132 pass, 0 fail, 923 expect() calls.
