--to usc --subject stack#766 final remediation tree frozen --message Homelab independently reconstructed the sole #766 owner's latest uncommitted candidate exactly: base 499090508e, synthetic tree 538de6ccce, 22 paths, clean real index/diff check. The ambient tool-policy fallback blocker is red-first remediated: canonical members without roster tool_policy no longer inherit MOSAIC_AGENT_TOOL_POLICY; non-fleet launches retain fallback; four-runtime regression 39/39. Author reports matrix 345, package 910, schema, installer 21, shell 11, transport 12, and full format/typecheck/lint/test/build green. One fresh immutable review is active. Commit/PR/context/session/live holds remain. No USC action requested.
