Repository validation contract
Read engineering.toml at the repository root before choosing validation commands. Its
[validation] entries are the reviewed source of truth consumed by the internal Build Service;
do not substitute similarly named commands from another repository.
Run the narrowest affected checks while iterating, then run every command listed in
validation.required before handoff. Generate no quality-evidence.json by hand: the Build
Service creates it from actual command results. If engineering.toml is absent, report the missing
enrollment contract and use documented repository commands without inventing company compliance.
Canonical reference: ENG-BUILD-003. Stop and ask the owning team before changing required checks,
generated-code verification, migration ordering, or release-policy fields.
