Fixes 2 critical, 2 important, and 5 minor findings from review of 069edcb:
- C1: add a happy-path test that reaches postOcrEscrow.ts's escrowLockFloor
call and asserts the locked amount; verified it fails against a bare
economicTotal and passes against the real code.
- C2: gate /v1/ocr/extract (auth + rate limits) before the 16mb body parser
so an unauthenticated caller can no longer force a full buffer/JSON.parse.
- I2: hoist result/used/escrowRef in the OCR one-shot handler so the failure
path records escrow_ref/supplier/cost when an escrow was actually posted,
and emit an ocr_failed structured log line mirroring ocr_settled.
- I3: export venueAttribution and cover its sanitization directly; add a
stubbed happy-path route test asserting the first-party-brokered
disclosure label reaches the response.
- Minor: drop unused hfWeightsSource end to end, rename a misleading test,
make the OCR capability template's pinning language conditional on the
self-hosted upstream, tighten the /v1/ocr path-prefix guard, and make
preflight's required_lovelace use the same escrowLockFloor the builder
locks (exported from the shared tx barrel for gateway use).
