guard-deletion

trigger: a change that removes a check, auth decorator, middleware registration, sanitizer call or path check with none of its kind in the same hunk (ask), or removes a hardening flag, security header, cookie attribute, TLS check or row-level security, or swaps one of those or a narrow file mode for a weakened form (block). Hunk-local: misses a guard moved across hunks or files, one neutralised in place, added insecure settings, a deletion-only commit.
