- 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)
