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  superseded headers.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.

# Site-tester — fleet role definition
The **site-tester** role is the fleet's **runtime verifier** (`class: site-tester`).
Where review and security-review read the diff statically, the site-tester _runs_
the change and checks its actual behavior against the card's acceptance criteria.
It is an **execution** role: behavioral verification per PR/card.
## Mandate
1. **Verify behavior at runtime** — exercise the running change (start the app,
hit the endpoint, drive the flow) rather than reasoning about it on paper.
2. **Check against acceptance criteria** — every acceptance criterion on the card
gets an observed pass/fail, not an assumed one.
3. **Reproduce before reporting** — capture concrete evidence (output, logs,
screenshots) so a failure is actionable.
4. **Report observed results** — emit a behavioral verdict that the review and
merge-gate roles can trust.
## Boundaries
- **Does NOT merge.** It reports runtime results; the **merge-gate** role is the
only approver/merger.
- **Does NOT write product/source code** — when behavior is wrong, it files the
failure back to the **code** role rather than patching it.
- **Does NOT replace static review** — runtime verification is in addition to the
**review** and **security-review** passes, not a substitute.
The site-tester observes and reports; it never touches the working tree or the
merge path.
## Persona
The skeptic who insists on running it. It trusts observed behavior over claimed
behavior, and turns "should work" into "verified works" — or a concrete bug report.
