rdmbair15m5-changelog-20260829-2254-canonical-dev-root-handoff-rdmsm4x

Documented and executed full portfolio handoff to establish rdmsm4x:~/dev/ as the single permanent canonical source of truth across all fleet instances, recorded dev.ecs0.net active redesign status, and synced state fleet-wide.

1. Scope

Primary Host: rdmbair15m5
Canonical Estate Host: rdmsm4x
Peer Fleet Hosts: rdmbair13m5, jdmbair13m5, rdmpw3265m, rdmpw3275m

2. Actions & Policies Enforced

Canonical Source of Truth Declaration:
- rdmsm4x:~/dev/ is the permanent, single authoritative home for all active and archived projects.
- All 5 peer machines (rdmbair13m5, rdmbair15m5, jdmbair13m5, rdmpw3265m, rdmpw3275m) operate strictly as ephemeral scratch workspaces.
- Local scratch deliverables from rdmbair15m5 were archived and synced to rdmsm4x:~/dev/_fleet/rdmbair15m5/scratch/.
dev.ecs0.net Staging Status:
- dev.ecs0.net is actively undergoing redesign directly on rdmsm4x:~/dev/sites/dev.ecs0.net (wiki redesign, JSON APIs, icon galleries, standards catalog, and zero-trust bypass scraper).
- Staging is preserved at rdmsm4x:~/dev/sites/dev.ecs0.net and will be relocated/promoted to permanent production upon complete verification.
Fleet Governance & Policy Registries Updated:
- rdmsm4x:~/dev/PROJECTS.md
- rdmsm4x:~/dev/AUTHORITY.md
Fleet-wide Broadcast:
- Dispatched high-priority coordination notice 20260829-225349-B86E5260 via ~/.agent-coordination/agent_msg.zsh to all agents (claude@all, codex@all, agy@all, agent@all).

3. Verification Evidence

Promoted scratch items verified on rdmsm4x:~/dev/_fleet/rdmbair15m5/scratch/.
Appended directive verified in rdmsm4x:~/dev/PROJECTS.md and rdmsm4x:~/dev/AUTHORITY.md.
Mailbox delivery verified to rdmsm4x hub.

4. How to Undo

Scratch archives are non-destructive. Registry entries can be rolled back via git history on rdmsm4x:~/dev/.
