"""Assemble the L10 continuity panel into a structured, freeze-gateable report. The panel runs the soaks the predicates need (an uninterrupted baseline, a reboot leg, and two crash-recoveries), evaluates every predicate, and emits a structured report with per-predicate PASS/FAIL, metrics, the explicitly *not-covered* legs (no silent skips — CLAUDE.md), and a **deterministic digest**. The digest is a SHA-256 over only the hardware-stable evidence: the canonical ``trace_hash`` sequence (``core.cognition.trace`` already rounds floats so the hash is stable across hardware) and each predicate's ``(name, passed)`` verdict. It deliberately EXCLUDES RSS, wall-clock, and raw float metrics, which are not reproducible across machines. The digest is the freeze handle: pin it once the lane is trusted and a regression flips it.
