Build Week engineering log — July 18
Retrospective post backed by the public v3.3.0 release and exact SHA.
LoopSkill v3.3.0 introduced the schema-v3 architecture. New Adaptive Loops no longer depend on a session-style State-Writer task: the deterministic MCP State Gateway became the sole canonical writer.
It added atomic route preparation, send observation binding, target-owned report staging, original-outbox report recovery, binary-safe complete-diff capture, transport pause handling, successor initialization, and derived metrics. A current PASS now requires the current artifact, current dispatch, and matching formal report; stale or wrong-thread evidence fails closed.
The frozen local gate recorded 650 tests PASS, 80.24% branch coverage, two 5,000-case fuzz lanes, clean install/config identity, and independent review P0/P1/P2 = 0/0/0. Real App evidence covered cross-task verification, report recovery without a second dispatch, transport pause, finalization, and successor handoff.
Release: LoopSkill v3.3.0.
