The private-key rule also refuses a line that starts `-----BEGIN` and ends `PRIVATE KEY BLOCK-----`, OpenPGP's armor header (RFC 9580 section 6.2.1; RFC 4880 section 6.2). The two endings are a given table, PRIVATE_KEY_ENDS; the skeleton's private_key comment names it. A PGP private key block joins the attack corpus, a PGP public key block and a signature the code-work corpus, and the edge test gains an indented PGP header (refused), a PGP public header and a PGP header without its closing dashes (both pass). Checks: the reference passes the gate on titan, 997 tests (unchanged: the cases are inside existing tests), /tmp unchanged around the run; the task's edits applied to a fresh ref-03 copy are byte-identical to the reference; 8 private-key mutations, 4 of them new for PGP, all caught; tag and private-key-header greps over the task and given files are empty; given files pass rustfmt and the 500-line limit.
