Two follow-ups from the verification runs:
1. skill-size-budget's catalog estimate still flaked under --parallel
(8356, then 8041, vs 4177 solo) even after filtering to tracked
skills: sibling workers REGENERATE real SKILL.md files mid-run, so
any live-tree read is a moving target. The ratchet now reads each
tracked skill's frontmatter from git show HEAD: — the catalog that
ships — which no concurrent worker can perturb.
2. agent-sdk-runner unit pins asserted the old Opus default through the
default-flow fixtures; flipped to the Sonnet default (the explicit-
override pass-through pins keep Opus — that path is unchanged).
