- ADR 0008 gave the marker-clear to to-spec, but the frontier runs tickets and
  to-spec doesn't own tickets (ADR 0006). Clear now belongs to the republisher:
  to-spec for a spec, to-tickets for a ticket. to-tickets gains the missing
  clear-on-republish instruction; ADR 0008 generalised to 'the republisher'.
- guide no longer says 'come back twice' (counter phrasing) — routes to grill
  on a returned marker (state fires on first mark), so it stops sending work to
  a spec-execution that would refuse it. Skill + docs page.

version 0.9.2 -> 0.9.3; check + validate --strict green.
