synth v0.81.0

What's Changed

• v0.81 scope: out of population is indistinguishable from compliant, and the anchor moves to v0.80.0 by @avrabe in #1477
• v0.80 follow-up: RQ-80-NPM declares issue-scope outlives, so a half-delivery stops reading as a whole one by @avrabe in #1478
• v0.81 record: one premise REFUTED by its own criterion, one blocker with the human action named, one filing at nineteen by @avrabe in #1479
• v0.81 gates lane: the silent artifact, the unclassified verdict, and the pin sweep's first test by @avrabe in #1480
• v0.81 SHEXIT lane (#1474): a failing git command cannot produce a verdict, and two contradicting gates agree by @avrabe in #1481
• v0.81 JESSDIVERGE3 lane (#1436): three mechanisms refuted, a dead release trigger, and a remedy the downstream had refused by @avrabe in #1482
• v0.81 release: the workspace moves to 0.81.0, the cold review lands, and two issues outlive their artifacts by @avrabe in #1483
