34 commits to Bow & Bridge from Tue 8 Sep to Wed 9 Sep 2026. A two-day operations pass after a review of the intake chain found that one volume had been offered to the OCR station 10,506 times. I wrote the pipeline’s limits down as a contract (fifteen numeric ceilings read from disk) and made the board, the status command and the alerts all report against the same lines.
Pipeline figures for the week: 9,316 pages read, 335 volumes unlocked, 9 records published and 738 corrections added.
- Fixed the admit storm: one volume the station could never fit had been asked 10,506 times; the admission rung is now paced by work done, and the drain front rotates instead of starving.
- Wrote the operations contract: fifteen ceilings (queue depths, run times, log sizes) read from one file, with a nightly uncapped guard pass and a station ledger that records every page ask.
- Stopped the miner minting bare surnames: a single-token name is refused, and a guard catches any that got through.
- Cut the claim-to-transcript link check from 9,219 lookups to one batched query, and stopped two PHP warnings that had grown the debug log to 174 MB.
- Fixed four guards that had quietly stopped running, and an intake stall where fetches waited on OCR they did not need.
