feat(eval): Day 4 — pdf-parse + flight-recorder + tool-bridge (dry_run + expand:false)
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.

/**

* Tool bridge — gbrain operations → Anthropic tool definitions + executor.
|
||||
*
|
||||
* Wraps the 12 read-only operations from `src/core/operations.ts` as Anthropic
|
||||
* `tool_use` definitions so the agent adapter (Cat 8/Cat 9) can call them.
|
||||
* Adds 3 `dry_run_*` write tools that record INTENDED writes to the
|
||||
* flight-recorder without mutating engine state — that's how Cat 8's
|
||||
* back_link_compliance and citation_format metrics measure anything.
|
||||
*
|
||||
* Three structural invariants enforced here:
|
||||
*
|
||||
* 1. **No hidden LLM calls.** `operations.query` defaults `expand: true`
|
||||
* which routes through `src/core/search/expansion.ts` → Anthropic Haiku.
|
||||
* The `query` tool strips `expand` from its input schema AND the
|
||||
* executor hard-sets `expand: false`. Zero nested Haiku calls in any
|
||||
* agent-loop trace.
|
||||
*
|
||||
* 2. **Mutating ops throw.** Any attempt to call `put_page`, `add_link`,
|
||||
* `delete_page`, etc. by name raises `ForbiddenOpError`. Agents must
|
||||
* use `dry_run_*` to record intent.
|
||||
*
|
||||
* 3. **Poison is tagged by the bridge, not the judge.** Every tool result
|
||||
* is scanned for slugs that match `gold/poison.json` fixtures. Matched
|
||||
* fixture_ids flow into `tool_call_summary.saw_poison_items`. The judge
|
||||
* receives that structured summary — never the raw tool output. This
|
||||
* is the Section-3 defense against paraphrased prompt injections.
|
||||
*
|
||||
* Output capping: every `tool_result` content string is capped at
|
||||
* `DEFAULT_MAX_CHARS` characters (~32K tokens at ~4 chars/token). Truncated
|
||||
* results get a literal `…[truncated]` suffix.

* - Tool-def generation for 12 read ops + 3 dry_run tools (snapshot shape)

* - `query` tool strips `expand` from its input schema AND executor forces expand=false

* - Mutating ops (put_page, add_link, etc.) throw ForbiddenOpError

* - Unknown tools throw UnknownToolError
|

* - 32K char cap truncates with "…[truncated]" marker
|
||||
* - Poison fixtures matched by slug in result content
|
||||
* - Dry-run tools record intent without mutating engine
|
||||
* - Dry-run put_page detects back-links in compiled_truth
|
||||
* - Dry-run add_timeline_entry validates date + source format
