Absent is now OK (OWASP recommends leaving it unset or set to 0),
and filtering mode (bare 1 or 1; report=...) is Warn since selective
script rewriting can itself introduce XSS. 1; mode=block stays Info.
Detect CSP weaknesses individually (unsafe-inline, unsafe-eval, missing
default-src/script-src, permissive sources on script-src or its
default-src fallback) instead of a single catch-all "unsafe" code, and
honour CSP3 fetch-directive fallback via EffectiveSources/WildcardSource
helpers. Validate Permissions-Policy values: warn when a powerful
feature (camera, microphone, geolocation, payment, sensors, …) is
granted to all origins. Add a SameSite aggregate state on cookie audits
so callers get the global ratio alongside per-cookie diagnostics.
