docs(fleet): consolidate north-star doctrine — budget governance + control plane + identity (#620-adjacent)
Folds Mos's two consolidated drafts (budgeting/200k/delegation + control-plane/
central-register) into docs/fleet/north-star.md as ONE conflict-free PR per the
merge-map. Doctrine only — no implementation.
- Stack table: +Central register (Postgres fleet schema) + Budget/spend governance
rows; PoC-socket-hygiene note.
- New '## Budget & token governance': even-spread pacing (Jason override), hard-cap
downgrade→queue→refuse ladder, multi-sub auto-routing, historical spend learning,
#558 budget CLI UX; + TTY OPS INVARIANT note.
- New '## Control plane & central register': Postgres fleet schema, gateway-API-only
access, dispatcher = @mosaicstack/forge pipeline engine + thin forge-exec adapter
(NOT a new daemon), register backs forge, 'board' role = forge BOD.
- Phased roadmap 4/5 annotated; Decisions of record (2026-06-22) extended (200k cap,
worker bound #8, delegation discipline, budget governance, spend mandate, unified
identity = Fleet, role-based session naming) + control-plane subgroup.
- Future enhancements: Matrix-on-local-homeserver future transport (F4) + tmux
attack-surface hardening. Assumptions extended.
Tracked separately / out of scope: #622 (spend template std), #623 (telemetry
product), #625 (tenant_id schema), #628 (forge-exec adapter).
