5 concurrent throwaway stacks deploy+rm. Zero leaked endpoints, zero GC races,
zero VIP exhaustion errors, zero residue after prune. /16 headroom confirmed cold.
Still waiting for Builder M1/M2 claims.
Cold verify: proxy 10.10.0.0/16 confirmed, all 9 services 1/1, routes 200/303.
No VIP exhaustion errors post-05:38Z. Step-0 guard verified present in upgrade-all skill.
[A2] filed: stale description in SKILL.md (guard text still says 'until that lands').
M1 and M2 pending Builder claim.
