verify-patch-sanity.py validates every active recipe .patch has internally- consistent hunk line counts — catching the 'malformed patch at line N' failure at commit/CI/preflight time instead of hours into a cook. This cycle hit that class three times (qtwaylandscanner, sddm, xwayland), each only discovered when cookbook tried to apply the patch. Running it across the repo found 29 latent malformed patches (validated against GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22'). They were harmless only because they sit in vendored recipes (baked, not re- applied) — but would fail on any version-bump re-derivation. --fix recounts the hunk headers (body untouched) and repaired all 29. Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test (test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats (empty placeholders, bare-@@ git hunks).

// Tests that the CFI mechanism treats classes in the anonymous namespace in
|
|
// different translation units as having distinct identities. This is done by
|
|
// compiling two translation units TU1 and TU2 containing a class named B in an

|
// anonymous namespace, and testing that the program crashes if TU2 attempts to
|
|
// use a TU1 B as a TU2 B.

// FIXME: This test should not require that the paths supplied to the compiler

// are different. It currently does so because bitset names have global scope
|
|
// so we have to mangle the file path into the bitset name.
