RR: regression suite re-run. BU: instrument baseline updated.
Enforced list: four walls in April, three at launch after the write-off rule retired with the authority it bounded, four from August. The tone fence is counted with the mitigations, not here. Every version pinned into the decision record.
Eval set: twelve cases at launch, thirteen after the August incident, nineteen at twelve months.
Rungs: two case classes moved in the year. Everything else sits where it launched.
Instruments: all six re-calibrated at the March swap. Each now carries a calibration date, a named owner, and a sentence saying what the threshold is for.
Margin, D. Okafor: the note on scope. Three rows above are accommodations. Each one took a meeting, each was reasonable, and none was worth blocking on the day. Diffed against the April declaration, they are a different product. We revoked one and wrote the rule that should have existed in January.
