Keep the HTTP session alive between weather polls (TODO #1). Re-creating the client each time forced a fresh TLS handshake inside the window where the UI is frozen. Measured on hardware: the fetch went from ~1.3s to ~80ms, so the pause is no longer long enough to matter once thermostat controls exist. The timeout drops from 30s to 10s once a session is warm, since only a cold handshake needs the longer budget. Any transport error or non-200 tears the session down so a half-open connection cannot poison every later poll. The response buffer is now reset per request rather than on HTTP_EVENT_ON_CONNECTED -- a kept-alive connection does not re-fire that event, so the buffer would have accumulated across polls. Indicate stale readings (TODO #2). After two consecutive failures the temperature dims and the status line shows the age. Age comes from tick counts, not weather_data_t.last_update: there is no SNTP client here, so time(NULL) starts at the epoch and any age derived from it is meaningless. Gate the touch readout behind UI_DEBUG_TOUCH, default off (TODO #3). Kept the note about LVGL not bubbling events to parents -- it documents a real trap. Delete main/utils (TODO #4); it had no callers outside itself. Also refreshed project_structure.txt, which was additionally missing i2c_bus and backlight. Lay out two 4MB OTA slots (TODO #5) while no devices are fielded, and document in the README that an OTA download cannot run while the panel is scanning -- the flash write faults the bounce-buffer ISR. Log the truncation warning once per response instead of once per chunk, and record the weather task's stack high-water mark (TODO #6): ~2400 bytes spare of 6144.

# Partition table for ESP32-S3-WROOM-1-N16R8 (16MB flash, 8MB octal PSRAM)
|
|
# as fitted to the CrowPanel 7" Advance.
|
|
#
|
|
# Two 4MB OTA slots. The app is ~1.1MB, so this is generous -- but the layout
|
|
# is fixed once devices are in the field, and re-partitioning later means
|
|
# reflashing each one over USB. Laying the slots out now costs nothing.
|
|
#
|
|
# NOTE: writing an OTA image is a flash write, and the panel's bounce-buffer
|
|
# refill ISR reads PSRAM, which shares the cache with flash on the S3. An OTA
|
|
# download while the panel is scanning WILL fault that ISR ("Cache disabled but
|
|
# cached memory region accessed"). Any OTA implementation must stop the panel
|
|
# for the download+write, or reboot into a dedicated updater mode first. See
|
|
# README "Memory notes".
|
|
#
|
|
# The former 12MB SPIFFS partition was dropped -- nothing mounted it. ~7.9MB
|
|
# is left unallocated for a filesystem or a third slot if either is ever
|
|
# needed; adding a partition to free space is safe, moving one is not.
