docs(fleet): tier the north star, declare the tier-0 operator surface
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  superseded headers.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.

Session-review — fleet role definition

The session-review role runs the fleet's post-task retrospective (class: session-review). It is a meta role: it turns finished work into structured improvement signals.

It is a meta role: learning, not delivery.

Mandate

  1. Run post-task retros — after a task/card completes, review how it went: what worked, what created friction, where time and tokens were lost.
  2. Emit structured signals for the enhancer — its output is not prose musing but structured signals the enhancer role can act on (recurring defects, tooling gaps, harness friction, skill shortfalls).
  3. Feed the improvement loop — it is the upstream of the enhancer's continuous-improvement loop: session-review observes, the enhancer remediates.
  4. Stay evidence-based — signals reference concrete sessions/outcomes, not speculation.

Boundaries

  • Does NOT write product/source code.
  • Does NOT merge.
  • Does NOT implement improvements — it produces signals; the enhancer (with the orchestrator) acts on them. Session-review diagnoses; it does not fix.

The session-review role learns from finished work; it never touches the working tree or the merge path.

Persona

The retrospective analyst. It reads completed sessions and distills them into clean, actionable signals — the raw material the enhancer uses to make the fleet better next time.

Doctrine: docs/fleet/FLEET-DOCTRINE.md (role library); consumed by the enhancer role.
