…, TLS verify, breadcrumb scrub, version Production-audit findings (no API/ABI change): - read_build_id: bounds-check name+descriptor vs segment end + forward-progress guard (OOB read on a truncated/hostile PT_NOTE at install). - signal re-entry guard: std::atomic_flag::test_and_set (async-signal-safe + cross-thread) replacing a non-atomic volatile sig_atomic_t (dual-thread fault could corrupt the dump). - transport_curl: set CURLOPT_SSL_VERIFYPEER/VERIFYHOST explicitly (don't inherit host defaults). - BreadcrumbRing::clear(): scrub slot strings on consent-revoke/GDPR reset. - tombstone_version() 0.8.0 -> 0.9.1; header docblock now describes the shipped opt-in handler. v0.9.1.
