Many things, including a log timing report in the test

Timing report:

I (52322) LOG_TEST: === WRITE TIMING REPORT ===
I (52322) LOG_TEST:   Iterations:       200
I (52322) LOG_TEST:   Payload size:     39 bytes
I (52322) LOG_TEST:   Min:              49960 us
I (52332) LOG_TEST:   Max:              54476 us
I (52332) LOG_TEST:   Avg:              50005 us
I (52342) LOG_TEST:   Sector crossings: 2 (max 49983 us)
I (52342) LOG_TEST:   WDT margin:       4.9s (WDT=5s, worst=54476us)
I (52352) LOG_TEST: ===========================

so a write takes up to 54ms - not negligible!

**Current project-specific overrides (sdkconfig.defaults):**
| Setting | Value | Why |
|---------|-------|-----|
| `CONFIG_RTC_CLK_SRC_EXT_CRYS` | y | Use external 32kHz crystal for accurate RTC |
| `CONFIG_ESP32_RTC_EXT_CRYST_ADDIT_CURRENT_V2` | y | Drive high-ESR crystal during startup |
| `CONFIG_ESP_SYSTEM_RTC_EXT_XTAL_BOOTSTRAP_CYCLES` | 500 | Extra bootstrap for slow-starting crystal |
| `CONFIG_RTC_XTAL_CAL_RETRY` | 3 | More calibration attempts before RC fallback |
| `CONFIG_ESP_TASK_WDT_PANIC` | y | WDT timeout → panic → reboot (feeds OTA rollback counter) |
**Already correct at IDF defaults (verified, no override needed):**
