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).

// The MSP430 is a 16-bit microcontroller RISC architecture. The instruction set
|
|
// has only 27 core instructions orthogonally augmented with a variety
|
|
// of addressing modes for source and destination operands. Entire address space
|
|
// of MSP430 is 64KB (the extended MSP430X architecture is not considered here).
|
|
// A typical MSP430 MCU has several kilobytes of RAM and ROM, plenty
|
|
// of peripherals and is generally optimized for a low power consumption.
