The per-skill budget guard measures skill files as they sit on disk, but
style-guide-selector grows at resolve time when the available-style-guide
catalog replaces its placeholder — 819 tokens against a 500 budget, so
the catalog tail was silently cut from every planning prompt. Worse, the
three base planning skills alone already exceeded the 4000-token phase
ceiling, which made the only domain skill of the phase undeliverable on
any prompt, with no warning anywhere. The skill budget now covers its
worst-case injection, the planning ceiling rises to 6000, and three new
guards keep the hole shut: augmented skills must fit their own budget,
every augmentation placeholder must declare a worst case, and the end-to-
end resolver must deliver the full phase without drops or truncation.
