CC 2.1.258: two fixes, zero surfaces

Lane adopt-cc-258, 2026-09-02. Two bullets, both fixes. Each verdict below carries the command that proved it; the full audit is docs/audits/cc-adoption-2.1.258-triage-2026-09-02.md.

What the CHANGELOG shows around 2.1.258

2.1.2522.1.2532.1.2542.1.255 (regression)2.1.2562.1.2572.1.258 (fix)

Dashed boxes have no CHANGELOG entry. The 2.1.258 bullet is the only place 2.1.255 is named upstream (grep -n '2\.1\.25[3-6]' CHANGELOG.md: one hit), so the macOS 12 break shipped in a build with no notes.

Not exercised here: the host is macOS 26.6.2, so the Monterey launch path was not run. The noop verdict rests on ork having no OS-version surface, not on observing the fix.
