STATUS: TODO
DEPENDS: I01
**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.
