Use when a sailing has no berth assigned, to find which allocation constraint rejected it and what would satisfy that constraint.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Berth check Explain why one sailing failed berth allocation. ## Steps 1. Run `./bin/ferrymark berth explain --sailing "$SAILING_ID"`. 2. Read the rejecting constraint from the command's output. 3. Look that constraint up in `conf/berth-policy.yaml`. 4. Run the command again with `--relax "$CONSTRAINT"` to see which berth would have been assigned. Report the constraint, the berth that relaxing it would free, and whether any other sailing already holds that berth.

How to install
mdr add stbenjam/skillsaw/berth-check@sha256:53a8342e8e49f82dThe line at the top of this page pins the label git:20260904.1b802e3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
