- Around line 30-70: Update extractBundle to retain each indexed file’s role as
well as its byte count, then check the entry against the role-specific size

Review comments at @scripts/biometrics-local-fit/cli.ts:
- Line 49: Validate `flags.jobs` in the CLI before passing it to
`fitCandidates`: convert it to a number and reject values that are not positive
safe integers, including malformed and non-positive inputs, with an error
identifying `--jobs`. Preserve `undefined` when the flag is omitted.

- Line 107: Update the holdout error in the parity check around report.split to
say that holdout results are not compared, rather than implying they are never

fitCandidates docstring in fit.ts to preserve this distinction between replaying
holdout results and parity comparisons.
Review comments at @src/biometrics/backtest/coordinator-lanes.ts:
- Line 5: Change the `exportDataset` lane assignment in `CoordinatorQueue` from
`read` to `work`, leaving the other lane assignments unchanged so dataset export
hashing does not occupy the serialized read lane.

Enforce the file-size limit before extraction writes the entry.
extractBundle accepts the indexed size and streams the complete RAW entry to disk. verifyBundle checks MAX_RAW_BYTES only after that write. A schema-valid archive with a RAW entry larger than 256 MiB can therefore exhaust local disk before verification rejects it.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Validate --jobs before you pass it to fitCandidates.
Number(flags.jobs) returns NaN for input such as --jobs four or --jobs 4x. In fit.ts Line 138, Math.max(1, Math.min(NaN, n)) then evaluates to NaN. As a result, prepareWorkerSlots creates zero slots, and runPool resolves without any replay. The first report then fails with Missing replay output for <cohort>. That message does not identify the invalid flag. Reject any value that is not a positive integer at the CLI boundary.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Correct the stale holdout error message.
The error text says "holdout is never replayed locally". That is no longer true. With --include-holdout, fitCandidates replays and scores holdout nights (fit.ts Line 119, Line 128). The README (Lines 61-63) documents that behavior. A user who scored holdout locally gets a wrong explanation for the parity refusal. The docstring in fit.ts Lines 111-113 ("Holdout nights are never replayed here") has the same contradiction. Restate the actual rule: parity compares only tuning and validation results.

Move exportDataset out of the serialized read lane.
CoordinatorQueue permits one active task per lane. prepareDatasetExport hashes every referenced RAW archive before it returns, so one export holds the only read slot for the full hash pass. Other read requests can wait during that pass. Repeated MCP calls can occupy the slot back-to-back. A guard alone would not remove this read-lane blockage.

Review comment at @src/biometrics/backtest/coordinator-lanes.ts at line 5:
Change the `exportDataset` lane assignment in `CoordinatorQueue` from `read` to
`work`, leaving the other lane assignments unchanged so dataset export hashing
does not occupy the serialized read lane.

Why
A backtest of 4 tuning nights takes about an hour on Pod 5, which rules out real parameter sweeps on the pod. This adds a way to fit biometric profiles on a laptop against data exported from the pod. The pod still confirms the winner.
Stacked on #836 (the build the pod runs). It's a separate PR; retarget to
devonce #836 merges.What
Export (pod)
GET /api/biometric-tuning/datasets/{id}/exportstreams one frozen dataset as a tar:bundle.json(each file with its size and SHA-256),manifest.json,snapshot.json, and theraw/<sha256>.RAW.gzarchives the snapshot references. Nothing else goes in.exportDataset) checks three things off the main event loop: the dataset content hash, that the live RAW references exactly match the snapshot, and each archive's SHA-256. The route hashes each archive again while streaming and aborts on any change.export_calibration_dataset(read-only) and tRPCdescribeDatasetExportreturn the index and the download path. Waveform bytes never pass through MCP.Local runner (
pnpm biometrics:local-fit,scripts/biometrics-local-fit/)verify,fit,sweep(grid, or the built-indefaultgrid of 18 points), andparity.replay_worker.run()(vialocal_replay.py), across parallel worker slots. Each slot gets its own hard-linked retained directory, because the read-only store serializes readers on its lock.evaluateBacktest. Output is one report per candidate per split, labelledexploratory-local/not_activation_evidence, plus a ranking by tuning HR error difference vs defaults, with validation alongside.runWaveformChildgets an optional trustedscriptentry, so the local runner reuses its exact event validation. The pod path is unchanged.Results on the 7 frozen nights (dataset 983a8da1)
