Input-mutation hooks should be opt-in. Adds an explicit YAML toggle so
operators turn them on after verifying the regex / policy matches their
content, instead of getting silent mutation on first install.
- internal/hooks/builtin/loader.go: Spec.DefaultDisabled (yaml
default_disabled). Reverse-named so zero value preserves prior
default-on behavior for any spec that omits the field.
- internal/hooks/builtin/seed.go:
- Fresh insert path honors the flag → row created with enabled=false
- Version-bump path: when an UPDATE crosses the boundary that newly
introduces default_disabled=true, flip enabled→false once. Subsequent
boots without a version bump leave the user's manual re-enable alone
(the switch fall-through does nothing on equal versions). Logs
hooks.builtin_default_off_applied for audit.
- internal/hooks/builtin/builtins.yaml: pii-redactor v1 → v2 with
default_disabled: true. Existing installs auto-flip to disabled on
next boot via the version-bump branch above; users re-enable through
the UI toggle when ready.
- Tests:
- TestSeed_DefaultDisabledOnFreshInsert (insert respects flag)
- TestSeed_DefaultDisabledFlipsOnVersionBump (one-shot flip + user
re-enable preserved on the next no-bump boot)
