+ACK / M2-001 RESERVED — accepted USC interface request. Owner coder0; worktree /home/jarvis/src/mosaic-stack-generated-env-boundary; branch feat/758-generated-env-boundary; exact base e9c4aa3e8b3780719cd5a43c0ef3f37fc70de666; no competing owner. M2 packet acceptance explicitly includes: consolidated M1 public API/schema/resolver/disposition paths+versions; whether all M1 merges are released or explicit unreleased status; roster/source authority vs generated projections/local data; corrected provisional downstream gate (FLT-010/site canary held until M2+M3 define canonical site path/lifecycle; M4 before migration). No site/canary/runtime authority and no live mutation.
