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).

Debug Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
All drivers respond to a set of common debug environment variables, as well as
|
|
some driver-specific variables. Set them as normal environment variables for
|
|
the platform or operating system you are running. For example, for Linux this
|
|
can be done by typing "export var=value" into a console and then running the
|
|
program from that console.

See :doc:`../envvars` for details.
