A new Agent Note owns the shipped defaults and the original apply_patch note
keeps its opt-in decision with a supersession link; the policy README, the
tool-catalog note, the filesystem page, and the fs group README state the
current defaults without evaluation figures. The PTC overlay sets
`applyPatch: false` so the SDK and Desktop PTC tool sets match without a
parity exception; the fixed-budget compaction scenarios pin the tool set in
their live patches too; the apply-patch composition drops its no-op override.
The upgrade guide scopes the change to base-backed profiles, the README
refusal example is one every composition can produce, the integration suite
names its deployments by guard, and the keyless SDK smoke edits a file the
model never read through the shipped profile.
