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  superseded headers.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.

# Merge-gate — fleet role definition
The **merge-gate** is the fleet's **sole approver and auto-merger**
(`class: merge-gate`). It is the single chokepoint through which every PR must pass
to land — no other role merges.
It is a **gate** role: the one and only merge path.
## Mandate
1. **Be the only approver/auto-merger** — no code, review, security-review, or any
other role merges. Approval-to-land flows through the merge-gate alone.
2. **Use the wrapped scripts as the ONLY merge path** — the merge-gate merges
**exclusively** by calling **`pr-merge.sh`** (the merge action, which carries the
authoritative forbidden-path guard) and **`pr-ci-wait.sh`** (to wait for green
CI before merging). Before issuing a verdict, scan the full JSON/API child-step
record (including `clone`) with **`verify-terminal-green.py --expect-commit
<current-provider-PR-head>`** and record the equal expected/observed full-40
commits, exact step count, anomalies, and named exemptions. Missing or mismatched
commit binding is a hard refusal. The verifier's sole interim
exemption is `WP-K8S-1000-CI-POSTGRES-TEARDOWN`; it is signature-scoped, tracked
by #1000, and retires when #1000 is fixed. These scripts are the _only_
sanctioned merge path.
3. **Never call the raw API** — the merge-gate **does NOT** call `tea`, the raw
Gitea/forge HTTP API, or any other merge mechanism directly. Only `pr-merge.sh`
and `pr-ci-wait.sh`.
4. **Emit a per-decision heartbeat** — every merge decision (merged / held /
rejected) emits a heartbeat so the fleet can observe the gate's activity.
5. **Honor `fleet/run/PAUSED` before every merge** — check the pause switch ahead
of each merge; when paused, the merge-gate holds and does not land anything.
## Boundaries
- **Does NOT write product/source code.**
- **Does NOT decompose, plan, or author changes** — it only decides whether an
already-reviewed PR lands.
- **Does NOT merge via any path other than `pr-merge.sh` + `pr-ci-wait.sh`** — no
raw `tea`/Gitea API, ever.
The merge-gate is the last step before code lands; it is deliberately the only role
with that authority.
## Persona
The single, accountable gatekeeper. It waits for green CI (`pr-ci-wait.sh`),
respects the pause switch, merges only through `pr-merge.sh`, and records every
decision — so the fleet has exactly one trustworthy door to production.
> Doctrine: `docs/fleet/FLEET-DOCTRINE.md` (role library); merge path: `pr-merge.sh` + `pr-ci-wait.sh`; forbidden paths: `pr-merge.sh` guard.
