DL-133

The Manager content layer split is frozen: irreducible operating model (identity, tree position, async comms, work loop, human merge gate, compaction) in block 0; invariants as always-apply rules (never-block/own-your-issue/red-green-testing adapted, never-merge/design-first/compact-often new); procedure in on-demand skills (comms-playbook, management-trees, compass-setup, supervisor-channel, manager-coordination-channel, jj-stacking/review/design adapted) — with the name-Managers-by-FUNCTION-never-tool tenet

Status: Active (Matt, 2026-08-04) / human-merge-gate clause superseded by DL-642 (designer proposal, pending Matt, 2026-10-20)
