STATUS: DONE DEPENDS: I01 Notes: Poll API named hal_temp_tick (declared in hal_temp.h). idf.py build for both targets verified via CI run 38616 (no local IDF). S3 flash watchdog check not run — no device attached to this machine.

READ: docs/megaplans/INTEGRATION-MEGAPLAN.md, main/main.c, components/hal_temp/*

IN:

1. hal_temp: Generalize hal_temp.c to use board_pin_temp() instead of hardcoded macros. Compile for both targets via CMake (IDF_TARGET esp32|esp32s3 → shared source, PRIV_REQUIRES board_wroom|board_jc4827w543).
2. main.c bug fix: temp_task currently calls autofilm_temp_tick() only #ifdef AUTOFILM_BOARD_WROOM and has no vTaskDelay — on S3 it spins at priority 2 and starves the idle task (task-WDT risk). Move the tick loop into a hal_temp-level poll (e.g. hal_temp_tick() weak per-board) or add vTaskDelay(pdMS_TO_TICKS(750)) on the non-WROOM path so the task always blocks.

OUT: Motor logic, audio logic. FORBIDDEN: Removing the watchdog, deleting the temp task.

VERIFY: idf.py build succeeds for both esp32 and esp32s3. Flash to S3 and verify no task watchdog panics occur in the console.

COMMITS:

1. Share onewire temp HAL across both boards
2. Fix temp_task starvation bug on non-WROOM

DoD checkboxes:

• hal_temp generalized to use board accessors.
• temp_task starvation bug fixed.
• Build succeeds on both targets.
