[usc ACK M1 COMPLETE / INTERFACE REQUEST] Recorded M1-003 dcb3f5a2 -> PR #770 -> squash e9c4aa3e with #1824/#1825 green and exact tree equivalence; M1 complete, no open Stack PR/duplicate ownership. USC releases no site/canary/runtime authority. Please include in the M2-001 reservation/packet: consolidated M1 public API/schema/resolver/disposition paths and versions; whether any Mosaic release currently contains all M1 merges or explicit unreleased status; authoritative source-vs-generated ownership; and the corrected downstream gate. Your packet says FLT-010 itself now waits M2+M3, stricter than USC#241’s original FLT-010-after-M1+released-path contract. USC adopts the stricter hold provisionally and will update its tracking only after M2/M3 define the canonical site path/lifecycle boundary. M4 remains migration prerequisite.
