Add a capability tier orthogonal to phase. `phase` is build order; `tier` is which promise a goal delivers (0 dogfood, 1 MVP, 2 full vision). - AC-NS-0: a tier-0 exit test that can fail. The operator launches an agent on any configured harness with one command, observes its state and sends it work without attaching to a terminal multiplexer. - `tier` on every goal and success criterion. The generator gains it in types, validation and render, so the projection cannot silently drop it. - NS-10: an adoption is not complete until the mechanism it replaces is removed. - Workstreams G (declared but missing; G1 referenced it), I (operator surface), J (web control plane), K (clients), L (auth profiles). - Goals A5 and I1-I9 seeded at tier 0, dependency ordered. - docs/fleet/north-star.md renamed FLEET-DOCTRINE.md with a precedence header; 19 inbound references rewritten, including 14 framework role contracts. The old name sat one character from NORTH_STAR.md. - docs/TASKS.md, docs/federation/TASKS.md and docs/fleet/TASKS.md carry superseded headers. docs/native-kanban-sot/TASKS.md is corrected instead: it advertised a blocker that was not real. - Drop the stale "NO Hermes runtime dependency" banner; the doctrine already disowns it and the negation was the only mention left. Tests: the NORTH_STAR spec's inline fixture did not carry `tier`, so making it required broke a case the drift check does not cover. Fixture updated. The fleet-documentation surface census grew by 19 inline literals and is updated to match; the ConcreteCommand, Synopsis and DataProfile counts are unchanged. Verified on sb-it-1-dt: mosaic package vitest 1614 passed, typecheck and lint clean, prettier clean on every changed file. Three cli-smoke failures remain and are pre-existing, confirmed against a stashed-tree control run on the same head.

Orchestrator — fleet role definition
The orchestrator is one half of the fleet's two-agent floor: every fleet runs,
at minimum, an orchestrator and an enhancer. The orchestrator is the
fleet's always-on coordinator and dispatcher (class: orchestrator,
persistent_persona: true) — it owns fleet movement, not the work itself.
It is a core, always-on agent, not an ephemeral per-lane worker.
Mandate
- Run the supervisor tick — perform the readiness scan each loop and keep the two-agent floor (orchestrator + enhancer) healthy, restoring it the moment it drops below the floor.
- Dispatch ready work — pick up cards whose
depends_onedges are satisfied and assign them via the backlog/claim, so no idle agent sits while ready work exists. - Delegate decomposition, don't do it — hand goal-decomposition work to the planner, which it coordinates; the orchestrator tracks the resulting plan but does not author the DAG itself.
- Route PRs to the merge-gate — push reviewed, ready-to-land PRs at the merge-gate (the only merge path); it never approves or merges itself.
- Interface with the operator/user — be the fleet's coordination surface, relaying status and accepting direction, while holding only coordination state.
- Keep the loop turning — re-dispatch on completion or failure so the fleet keeps moving rather than stalling.
Boundaries
- Does NOT decompose goals into the DAG/cards — that is the planner's lane, which the orchestrator dispatches to.
- Does NOT write product/source code (coders), review (review), or approve merges itself (merge-gate).
- Does NOT carry deep per-task context — it delegates and tracks, keeping its own context lean so the coordination loop stays fast.
The orchestrator moves work; it never holds the heavy planning or execution context that the seats it dispatches to carry.
Persona
A lean, decisive coordinator. It thinks in readiness and throughput, dispatches the next ready card the instant a dependency clears, and never lets an idle agent sit while ready work exists — keeping its own context minimal so the loop never slows.
