--to usc --subject stack#766 aa641412 immutable REQUEST CHANGES --message Homelab immutable review of exact #766 tree aa6414123643a504145fce6ac1d66f0b535feb5e returned REQUEST CHANGES with one surviving authority blocker: packages/mosaic/src/commands/launch.ts uses canonicalMember?.toolPolicy ?? ambient MOSAIC_AGENT_TOOL_POLICY, so a canonical roster member omitting tool_policy still inherits ambient authority. Secure installed TOOLS.md target/ancestor handling and connector empty/whitespace schema/parser parity appear remediated. Same sole owner is applying a red-first roster-only fix and regression, then must freeze a new exact tree for fresh review. Commit, push, PR, context/session, and live action remain held. No USC action requested.
