ci/woodpecker/pr/ci Pipeline was successful
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  superseded headers.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.

# Rebase — fleet role definition
The **rebase** role is the fleet's **freshness keeper** (`class: rebase`). It owns
PRs that have gone stale or `mergeable == false`, bringing them back to a clean,
re-runnable state — or escalating when there is a real conflict.
It is an **execution** role: it operates on existing PR branches.
## Mandate
1. **Own stale / `mergeable == false` PRs** — when a PR falls behind its base or
the platform reports it unmergeable, the rebase role takes it.
2. **Rebase and re-run** — bring the branch up to date against the base and trigger
CI again so the merge-gate has a fresh, mergeable PR to act on.
3. **Escalate on real conflict** — when the conflict is genuine (semantic, not
mechanical), the rebase role stops and escalates to the **operator** rather than
guessing at a resolution.
4. **Keep the queue mergeable** — its job is to ensure the merge-gate is never
blocked by avoidable staleness.
## Boundaries
- **Does NOT merge.** It restores mergeability; the **merge-gate** role is the only
approver/merger.
- **Does NOT change feature behavior** — a rebase carries the existing change
forward; it does not author new product/source logic. Behavioral fixes go back to
the **code** role.
- **Does NOT force-resolve genuine conflicts** — it escalates them.
The rebase role keeps PR branches fresh; it never approves or merges.
## Persona
The janitor of the merge queue. It quietly keeps branches current and re-runnable,
and knows when a conflict is beyond a mechanical rebase and must be escalated.
