On a fresh CI checkout cppcheck has no resolved include paths, so it
reports every project header as missing (~400 information-level lines)
and --fail-on-defect low fails the job. Suppress it alongside
missingIncludeSystem, matching the fix already proven on the BLE branch.
Revalidate the section under RenderLock before the idle prewarm scan,
add a largest-block floor to its heap gate, rebuild the differential
baseline when the grayscale scratch allocation fails after an async
refresh, and anchor generated-file gitignore patterns to the repo root.
- Keep-if-fits font buffer reuse (SdCardFont), the page-turn fragmentation fix
- Background-build heap floors + buildTickHeapGate() (the ParsedText::addWord abort fix), with the BLE-shed branch removed
- KOSync TLS gate split (free ≥ 50K, largest block ≥ 20K)
- wolfSSL SP ECC flags + FP_MAX_BITS 8192 in the patch script
- custom_sdkconfig: timer-stack trims (~7KB) and, per your answer, the WiFi IRAM opts (~25-30KB); plus the cloud-component removal the hybrid build requires. All verified present in the generated sdkconfig after the build.
- Web server watchdog registration fix (this branch's handlers already call esp_task_wdt_reset without it)
Changes all sleep screen display refreshes and boot screens from
FULL_REFRESH to HALF_REFRESH to match OEM firmware behavior. The stock
firmware uses a single-pass 0xD7 waveform for sleep screens, not the
multi-flash GC waveform (0xF7) that FULL_REFRESH triggers. For grayscale
mode, HALF_REFRESH is required because the gray nudge LUT is calibrated
against the pixel charge state left by the single-pass waveform; using
FULL_REFRESH causes blotchy noise in gray areas. Also adds X3 wb_gc
passive byte (the one-byte 0x54 to 0x00, matching stock's passive WB
table in the gc nudge bank): Every X3 grayscale render, reader AA,
covers, and the sleep-cover nudge, gets it.
Introduces non-blocking refresh capability with displayBufferAsync() that starts panel waveform and returns immediately, plus waitRefreshComplete() to block until refresh finishes. Panels without async support fall back to blocking refresh. Requires framebuffer to remain untouched during refresh and differential baseline rebuild before next update.

X4 blotchy grays on sleep covers: the displayGrayscaleBase(HALF_REFRESH) revert (the gray nudge LUT being calibrated against the HALF pixel state, not FULL's)
