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).

## When ICF has fewer than 1 Ki functions to segregate into equivalence classes,
|
|
## it uses a sequential algorithm to avoid the overhead of threading.
|
|
## At 1 Ki functions or more, when threading begins to pay-off, ICF employs its
|
|
## parallel segregation algorithm. Here we generate 4 Ki functions to exercise
|
|
## the parallel algorithm. There are 4 unique function bodies, each replicated
|
|
## 1 Ki times. The resulting folded program should retain one instance for each
|
|
## of the four unique functions.
|
|
|
|
## The symtab does not have a particular order. And even though we can expect
|
|
## some partial order, it is not possible to express that in FileCheck syntax.
|
|
## So just use -DAG
