 # SC-F001 Firmware — CLAUDE.md
 
-## Overview
+See `README.md` for full project documentation (hardware, architecture, protocols, algorithms).
-
-The SC-F001 is a **solar-powered automated crop harvesting robot** built on the ESP32. It drives a carriage horizontally via a drive motor and lifts/lowers a cutting head via a jack motor, with an auxiliary "fluffer" motor always running during operation. The firmware handles motor sequencing, safety interlocks, remote control, data logging, and a WiFi web interface.
-
-**Primary operational cycle:** Idle → Move Start Delay → Jack Up → Drive → Jack Down → Idle
 
 ---
 
-## Hardware Platform
+## Workflow
 
-**MCU:** ESP32 (Xtensa dual-core), IDF framework
+- **Minimize shell commands.** Every Bash call requires user approval. Prefer Read/Edit/Write/Glob/Grep tools. Only use Bash when a shell command is genuinely needed (e.g., `idf.py build`, git operations).
+- **Webpage build step:** After editing `webpage.html`, run `webpage_compile.py` to regenerate `webpage_gzip.h` before building.
+- **Don't touch git.**
+---
 
-**GPIO Map:**
+## sdkconfig Management
-| GPIO | Function |
-|------|----------|
-| 13 | Button interrupt (active low, pull-up) — also EXT0 wakeup |
-| 14 | Jack position sensor / encoder |
-| 16 | Drive encoder |
-| 19 | Aux sensor 2 (reserved) |
-| 21/22 | I2C SDA/SCL (400kHz) → TCA9555 I/O expander |
-| 25 | 433MHz RF receiver (RMT input) |
-| 26 | Solar charger bulk enable (RTC GPIO, holds across deep sleep) |
-| 27 | Safety sensor (active low) |
-| 32/33 | External 32kHz RTC crystal |
-| 36 (VP) | ADC: drive current sense |
-| 39 (VN) | ADC: battery voltage |
-| 34 | ADC: jack current sense |
-| 35 | ADC: aux current sense |
 
-**TCA9555 (I2C at 0x20):**
+**Two files, different roles:**
-- Port 0 (input): 2 physical buttons + 2 additional inputs
+- `sdkconfig.defaults` — checked into git. Contains only intentional project overrides with comments explaining why. Applied by `idf.py reconfigure` on top of IDF defaults.
-- Port 1 (output): 3× H-bridge relay pairs (DRIVE, JACK, AUX) + LEDs
+- `sdkconfig` — generated/modified by `idf.py menuconfig` or `reconfigure`. Contains every resolved setting. Also checked in for reproducibility, but treat `sdkconfig.defaults` as the source of truth for project-specific choices.
 
-**Motor / Bridge Specs:**
+**Rules:**
-- `BRIDGE_DRIVE` — 100A max, ACS37220 sense chip (13.2 mV/A, inverted polarity)
+- When changing a setting, add it to `sdkconfig.defaults` with a comment, then also apply it to `sdkconfig` so the next build picks it up without requiring `idf.py reconfigure`.
-- `BRIDGE_JACK` — 30A max, ACS37042 sense chip (44 mV/A)
+- Never hand-edit `sdkconfig` without also updating `sdkconfig.defaults` for the same setting — otherwise the change will be lost on the next `reconfigure`.
-- `BRIDGE_AUX` — 30A max, ACS37042 sense chip (44 mV/A)
+- Keep `sdkconfig.defaults` small and well-commented. Don't dump the full config into it.
+
+**Current project-specific overrides (sdkconfig.defaults):**
+| Setting | Value | Why |
+|---------|-------|-----|
+| `CONFIG_ESP_TASK_WDT_PANIC` | y | WDT timeout → panic → reboot (feeds OTA rollback counter) |
+| `CONFIG_RTC_CLK_SRC_INT_RC` | y | Use internal 150kHz RC oscillator — no external 32kHz crystal. Avoids failed XTAL probe that corrupts RTC slow memory. |
+
+**Already correct at IDF defaults (verified, no override needed):**
+| Setting | Value | Status |
+|---------|-------|--------|
+| `CONFIG_FREERTOS_CHECK_STACKOVERFLOW_CANARY` | y | Stack overflow detection via canary (method 2) |
+| `CONFIG_ESP_SYSTEM_PANIC_PRINT_REBOOT` | y | Print backtrace then reboot on panic |
+| `CONFIG_BROWNOUT_DET_LVL_SEL_0` | y | ~2.43V brownout on ESP32 3.3V rail (appropriate — battery low-V is handled by `LOW_PROTECTION_V` in FSM) |
+| `CONFIG_PARTITION_TABLE_CUSTOM` | y | Custom partitions.csv with ota_0 + ota_1 |

+Only **mdns** is used. The TCA9555 is driven by a custom raw I2C driver in `i2c.c` (not the `esp-idf-lib/tca95x5` library). LittleFS is not used.

-STATE_IDLE
-STATE_MOVE_START_DELAY      (1s)
-STATE_JACK_UP_START         (detect current spike → jack engaged)
-STATE_JACK_UP               (continue until timer/e-fuse)
-STATE_DRIVE_START_DELAY     (1s)
-STATE_DRIVE                 (encoder-based distance control)
-STATE_DRIVE_END_DELAY       (1s)
-STATE_JACK_DOWN             (reverse until e-fuse/sensor)
-→ back to STATE_IDLE
-
-STATE_UNDO_JACK_START       (emergency: reverse jack immediately)
-STATE_UNDO_JACK             (run until e-fuse/sensor)
-→ back to STATE_IDLE
-
-CAL_JACK_DELAY / CAL_JACK_MOVE          (jack calibration sequence)
-CAL_DRIVE_DELAY / CAL_DRIVE_MOVE        (drive calibration sequence)
-```
-
-**Guards before START:**
-- Remaining distance > 0 (leash protection)
-- Battery V ≥ `LOW_PROTECTION_V` (default 10V)
-- Safety sensor active (debounced stable)
-- All e-fuses not tripped
-
-**FSM Loop (20ms tick in `control_task()`):**
-1. `process_bridge_current()` — ADC → EMA → auto-zero → e-fuse
-2. `process_battery_voltage()` — ADC → EMA
-3. `sensors_check()` — drain ISR queue, update counters/debounce
-4. State machine transitions (timer + sensor + efuse checks)
-5. `driveRelays()` — write relay output from current state
-6. `send_fsm_log()` — 39-byte timestamped entry to flash
-
----
-
-## E-Fuse Algorithm (`power_mgmt.c`)
-
-Per bridge, each 20ms tick:
-1. Raw ADC → EMA filter (α = `ADC_ALPHA_ISENS`)
-2. Auto-zero: learn zero offset when motor is off + grace period expired
-3. Grace period: 250ms after relay closes (ignores startup inrush)
-4. **Instant trip:** I ≥ `EFUSE_KINST` × I_nom (default 2×)
-5. **Thermal trip:** heat accumulates as I²·Δt; dissipates at τ_cool rate
-6. **Auto-reset:** after `EFUSE_TCOOL` seconds of cooling (default 5s)
-
----
-
-## Safety Sensor Debouncing (Asymmetric)
-
-```
-LOW (safe):   1000ms make time  → slow to declare safe (SAFETY_MAKE_US)
-HIGH (break): 300ms break time  → fast to kill operation (SAFETY_BREAK_US)
-```
-
-Safety break → immediate `STATE_UNDO_JACK_START`.

+
+## Webpage (`main/webpage.html`)
+
+Single-file SPA. Compiled to a gzip binary embedded in firmware. All JS is inline.
+
+**Key globals:**
+- `const ge = (id) => document.getElementById(id)` — shorthand used everywhere
+- `let data = {}` — full `/get` JSON response, updated every poll cycle
+- `let paramTableCreated = false` — tracks whether the DANGER ZONE param table has been built yet
+- `let pollInterval` — handle for the 2-second `fetchStatus()` interval
+
+**Endpoints used by JS (all relative):**
+- `./get` — GET, returns full system status JSON; polled every 2 s by `fetchStatus()`
+- `./post` — POST `application/json`, handles commands + parameter updates
+- `./log` — GET/POST, binary log download
+- `./ota` — POST, firmware upload
+
+**POST body format** (`./post`):
+```json
+{ "cmd": "start", "parameters": { "KEY": value, ... }, "time": 1234567 }
+```
+All fields optional. `parameters` is a flat object of param key → value.
+
+**Input / parameter binding convention:**
+- Any `<input id="PARAM_<KEY>">` anywhere in the page is automatically updated by `updateParamTable()` on every poll (skipped if the input has class `changed` or is focused)
+- `onchange="markChanged(this)"` — adds class `changed` (green), enables `commit_btn` / `cancel_btn`
+- `commitParams()` (Save Changes button) collects all `.changed` inputs whose `id` starts with `PARAM_`, POSTs `{parameters: {...}}`, clears `changed` class
+- `cancel_btn` calls `location.reload()`
+
+**Sections (top to bottom):**
+1. Status display (voltage, state, distance, error flags) — auto-updated from `data`
+2. Schedule settings (`<details>`) — MOVE_START / MOVE_END / NUM_MOVES
+3. Remote Control (`<details open>`) — jog buttons + RF programming
+4. **WiFi Settings** (`<details>`) — WIFI_SSID, WIFI_PASS (STA mode disabled: NET_SSID/NET_PASS inputs commented out)
+5. **DANGER ZONE** (`<details>`) — calibration, version, OTA upload, log download, auto-generated parameter table, REBOOT/SLEEP
+
+**`updateParamTable()`:**
+- On first call: builds a `<table id="table">` row per parameter, sorted alphabetically, skipping `WIFI_PARAM_KEYS = {NET_SSID, NET_PASS, WIFI_SSID, WIFI_PASS}` (those live in the dedicated WiFi section)
+- On subsequent calls: updates existing input values (skips changed/focused inputs); if a new key appears, rebuilds
+
+**Modal helpers** (all return Promises):
+- `modalAlert(message, title?)` — OK only
+- `modalConfirm(message, title?)` — OK / Cancel → resolves `true`/`false`
+- `modalPrompt(message, title?, defaultValue?)` → resolves string or `null` on cancel
+
+**Adding a new dedicated UI section:**
+1. Add `<input id="PARAM_<KEY>" onchange="markChanged(this)"/>` in HTML
+2. Add key to `WIFI_PARAM_KEYS` (or equivalent filter set) in `updateParamTable()` so it isn't duplicated in the raw table
+3. Optionally add a dedicated apply function following `applyWifiSettings()` pattern

+## GPIO Map (lines 13–28) — Wrong for active board (V5)
+
+The table documents the **V4 pinout**. On V5 the sensor and ADC GPIOs are completely different:
+
+| README says | V4 pin | Actual V5 | Source |
+|---|---|---|---|
+| GPIO14 = Drive encoder | ISENS2 | **GPIO14 = JACK position sensor** | `sensors.c:26` |
+| GPIO16 = Jack position sensor | ISENS3 | **GPIO16 = not used** (V5 uses GPIO14 for JACK) | `sensors.c:26` |
+| GPIO19 = Aux sensor 2 (reserved) | BATTERY | **GPIO19 = DRIVE encoder** | `sensors.c:26` |
+| GPIO23 = *missing* | — | **GPIO23 = AUX2** (unused, J3 unreliable) | `sensors.c:26` |
+| GPIO34 = ADC: jack current sense | ISENS2 | **GPIO34 = V_ISENS_MAIN** (shared ACS) | `power_mgmt.c:49` |
+| GPIO35 = ADC: aux current sense | ISENS3 | **GPIO35 = battery voltage** (ADC1_CH7) | `power_mgmt.c:51` |
+| GPIO36/VP = ADC: drive current sense | ISENS1 | **GPIO36 = V_VOC** (OC threshold diag) | `power_mgmt.c:50` |
+| GPIO39/VN = ADC: battery voltage | BATTERY | **GPIO39 = FAULT** (digital input, ACS37220) | `power_mgmt.c:52` |
+
+The `sensors.h` enum comments (lines 19–22) are also stale — they list V4 pins but the V5 pins are assigned at runtime in `sensors.c:26`.
+
+---
+
+## TCA9555 description (line 32) — Wrong
+
+> Port 1 (output): 3× H-bridge relay pairs (DRIVE, JACK, AUX) + LEDs
+
+LEDs are on **Port 0** (P05–P07), not Port 1. See `i2c_set_led1()` at `i2c.c:98` writing to `TCA_REG_OUTPUT0`.
+
+---
+
+## ACS chip statement (line 47) — Unqualified
+
+> All power goes through a ACS37220 sense chip (13.2 mV/A)
+
+True for V5 (single shared ACS37220). On V4, JACK and AUX use **ACS37042 (44 mV/A)** — `power_mgmt.c:457-458`.
+
+---
+
+## Software Architecture diagram (lines 53–66) — Missing steps
+
+The init sequence omits:
+- Factory-reset detection loop (`main.c:174-227`)
+- `rtc_restore_time()` after `storage_init()` (`main.c:232`)
+- `adc_post()` after `log_init()` (`main.c:236`)
+- `storage_post()` (`main.c:237`)
+- OTA rollback counter check (`main.c:241-278`)
+- `send_bat_log()` at boot (`main.c:282`)
+
+---
+
+## Main loop description (lines 68–73) — Major omissions
+
+Missing from the described main loop:
+- **Soft-idle polling path** (`main.c:340-363`) — handles wake-on-button, wake-on-alarm, solar FSM, and shutdown timer during sleep. This is ~25% of the main loop body.
+- Button hold-to-reboot logic (`main.c:388-397`)
+- Triple-tap detection (`main.c:411-431`)
+- Alarm-triggered `FSM_CMD_START` (`main.c:496-499`)
+- Periodic `send_bat_log()` every 120s in IDLE (`main.c:450-452`)
+- `esp_task_wdt_reset()` at end of each tick (`main.c:503`)
+
+---
+
+## FreeRTOS Tasks table (lines 76–84) — Wrong priorities, missing task
+
+| Task | README says | Actual priority | Source |
+|---|---|---|---|
+| UART task | "default" | **12** | `uart_comms.c:294` |
+| RF 433 task | "default" | **5** | `rf_433.c:223` |
+| BT HID task | "default" | **4** | `bt_hid.c:583` |
+
+Missing task: **log_writer** (priority 5, created by `log_init()` at `storage.c:1069-1076`).
+
+---
+
+## Key Files — `hard_ui.c` doesn't exist
+
+`hard_ui.c` listed at line 107 — no such file in `main/`. Either stale or was removed.
+
+---
+
+## FSM state diagram (lines 113–129) — Missing state
+
+`STATE_DRIVE_FLUFF_START` is omitted. Actual sequence:
+
+```
+START_DELAY → JACK_UP_START → JACK_UP → DRIVE_START_DELAY → DRIVE_FLUFF_START → DRIVE → DRIVE_END_DELAY → JACK_DOWN
+```
+
+Cal states listed as `CAL_JACK_DELAY` but actual enum names are `STATE_CALIBRATE_JACK_DELAY`, `STATE_CALIBRATE_JACK_MOVE`, `STATE_CALIBRATE_DRIVE_DELAY`, `STATE_CALIBRATE_DRIVE_MOVE`.
+
+---
+
+## FSM Loop — wrong log size (lines 137–143)
+
+> send_fsm_log() — 39-byte timestamped entry
+
+`LOGSIZE = 25` at `control_fsm.c:179`. The actual 25-byte layout is:
+
+```
+[0:8]   ts_ms (u64)
+[8:12]  bat_V (f32)
+[12:16] current_A (f32)   — combined, not per-bridge
+[16:18] counter (i16)
+[18:19] sensors (u8)
+[19:23] heat (f32)        — max across bridges
+[23:25] i2c_out (u16)
+```
+
+---
+
+
+
+---
+
+## `/log` HTTP endpoint (line 184) — Wrong method
+
+> `/log` — GET
+
+Registered as `HTTP_ANY` (`webserver.c:870`). Handles both GET and POST (`webserver.c:150-153`).
+
+---
+
+## UART `POST:` example (line 189) — Wrong syntax
+
+> POST: {json}
+
+The UART handler (`uart_comms.c`) receives raw JSON strings, not HTTP-style method prefixes.
+
+---
+
+## Flash partitions (lines 212–220) — Wrong offsets and sizes
+
+| Partition | README | Actual (`partitions.csv`) |
+|---|---|---|
+| post_test | offset 0x310000, 4K | offset **0x3F0000**, 4K |
+| params | offset 0x311000, **16K** | offset **0x3F1000**, **32K** |
+| log | offset 0x315000, **~4.9MB** | offset **0x400000**, **4096K** |
+
+Missing from table: NVS (0x9000, 16K), otadata (0xD000), phy_init (0xF000), **ota_0 (0x10000, 1984K)**, **ota_1 (0x200000, 1984K)**.
+
+---
+
+## Log entry format (lines 222–234) — Describes old 39-byte format
+
+The 39-byte layout with separate per-bridge currents and heats doesn't match `send_fsm_log()` which uses 25 bytes (combined current, single max heat, adds `i2c_out`).
+
+---
+
+## Parameter count — Off by one
+
+> 48-param NVM table (`storage.c/h` description, line 97)
+
+`storage.h:72-121` defines **49** parameters (check `NUM_PARAMS` from the enum).
+
+---
+
+## Key Parameters list (lines 236–242) — Missing 30+ params
+
+Missing: `ADC_ALPHA_BATTERY`, `ADC_ALPHA_ISENS`, `ADC_ALPHA_IAZ`, `ADC_DB_IAZ`, `JACK_I_UP`, `JACK_I_DOWN`, `V_SENS_K`, `V_SENS_OFFSET`, `EFUSE_INRUSH_US`, `EFUSE_TAUCOOL`, `FLUFF_PREDRIVE_MS`, `CHG_LOW_V`, `CHG_LOW_S`, `CHG_BULK_S`, `RF_PULSE_LENGTH`, `LOW_PROTECTION_S`, `BUILD_VERSION`, `BOOT_TIME`, `JACK_IS_DOWN`, `WIFI_CHANNEL`, `NET_SSID`, `NET_PASS`.
+
+---
+
+## Deep sleep claim (line 248) — Incorrect
+
+> deep sleep is disabled (soft idle instead)
+
+`hibernate_enter()` at `rtc.c:184` calls `esp_deep_sleep_start()`. Deep sleep is used for hibernate mode (triggered by explicit web/UART command). Soft idle is the inactivity-triggered default, but deep sleep is not disabled.
+
+---
+
+## Factory reset GPIO reference (lines 270, 280, 354) — Wrong pin
+
+> Hold GPIO13 button / power cycle with GPIO13 held
+
+GPIO13 is the **NCA9535 INT line**, not a button. The actual button state is read via I2C (`i2c_button_held_raw(0)` at `main.c:176`). The user holds the physical button on the I2C expander, not GPIO13.
+
+---
+
+## Battery voltage GPIO (line 326) — Wrong for V5
+
+> Battery voltage: GPIO39
+
+On V5, battery voltage is on **GPIO35** (ADC1_CH7). GPIO39 is the **FAULT digital input** (`power_mgmt.c:51-52`). This correctly describes V4 only.
+
+---
+
+## "fluffer motor always running" (line 3) — Overstated
+
+> auxiliary "fluffer" motor always running during operation
+
+The fluffer (AUX) only runs during `STATE_DRIVE_FLUFF_START` and `STATE_DRIVE`. It does not run during jack-up, jack-down, or delay states (`control_fsm.c:716-776`).

+6. `send_fsm_log()` — timestamped entry to flash
+

+
+## E-Fuse Algorithm (`power_mgmt.c`)
+
+Per bridge, each 20ms tick:
+1. Raw ADC → EMA filter (α = `ADC_ALPHA_ISENS`)
+2. Auto-zero: learn zero offset when motor is off + grace period expired
+3. Grace period: 250ms after relay closes (ignores startup inrush)
+4. **Instant trip:** I ≥ `EFUSE_KINST` × I_nom (default 2×)
+5. **Thermal trip:** heat accumulates as I²·Δt; dissipates at τ_cool rate
+6. **Auto-reset:** after `EFUSE_TCOOL` seconds of cooling (default 5s)

+
+## RTC & Timekeeping
+
+**Time source:** `esp_timer` (40 MHz APB crystal, ~20 ppm accuracy). The external 32.768 kHz crystal on GPIO32/33 is present on the PCB but **not used** — deep sleep is not used normally (soft idle instead), so RTC slow clock accuracy is irrelevant. The RTC slow clock uses the default internal RC oscillator.
+
+**`rtc_xtal_init()` in `rtc.c`:** Configures the button GPIO (GPIO13); no crystal bootstrap or sleep wakeup sources.
+
+**Time persistence across resets:** `rtc_save_time()` writes the current unix timestamp to NVS (namespace `"hw"`, key `"rtc_time"`). On boot, `rtc_restore_time()` tries `RTC_DATA_ATTR` first, then falls back to NVS. This ensures time survives software resets even when the bootloader reloads RTC slow memory. The saved time will be stale by the reboot duration (~2s), which is acceptable.
+
+**Diagnosing time issues:** Run `RTCDEBUG` over UART. Reports current time, sync time, elapsed since sync, next alarm, uptime, and soft idle state.
+
+---
+
+## Button & LED Behavior
+
+Single physical button (button 0 via TCA9555 I2C expander) controls all interactions. All logic lives in the main loop (50ms tick) in `main.c`.
+
+### Button Actions by State
+
+**IDLE — Triple-tap to start:**
+- 3 taps within a 2-second window triggers `FSM_CMD_START`
+- Start fires immediately on the 3rd tap
+- LED feedback: 1 tap → LED 1, 2 taps → LED 1+2, 3 taps → LED 1+2+3 (then start)
+- LEDs persist until next tap or window expiry; counter resets on expiry
+
+**IDLE / CALIBRATE — 3-second hold to reboot:**
+- Saves RTC time to NVS, then calls `esp_restart()`
+- LED progression: off (0–750ms) → LED 1 (750–1500ms) → LED 1+2 (1500–2250ms) → LED 1+2+3 (2250–3000ms) → flash all (6× at 150ms) → reboot
+
+**Moving states** — any tap sends `FSM_CMD_UNDO`
+
+**UNDO state (UNDO_JACK_START)** — any tap sends `FSM_CMD_STOP` (emergency stop)
+
+**Calibration states** — tap advances through calibration steps (unchanged)
+
+**Factory reset** — power cycle with GPIO13 held for 10 seconds. Resets all params and erases log/post_test partitions. Preserves NVS (board_rev, BT pairing, RTC time). Only triggers on `ESP_RST_POWERON` or `ESP_RST_EXT`.
+
+### LED Status Indicators
+
+**Physical LED layout** — the three LEDs are wired to TCA9555 port-0 pins
+P05, P06, P07. Read bottom → top when checking error codes:
+
+| TCA pin | Bit | Physical position | Called |
+|---------|-----|-------------------|--------|
+| P05     | 0   | bottom            | LED1 |
+| P06     | 1   | middle            | LED2 |
+| P07     | 2   | top               | LED3 |
+
+A pattern written as `001` (LSB first) means **only the bottom LED is lit**,
+`100` means **only the top LED is lit**, and `111` means all three.
+
+| State             | Pattern                                      | Timing                                    |
+|-------------------|----------------------------------------------|-------------------------------------------|
+| Idle              | LED1 blink                                   | 0.5Hz (1s on / 1s off)                    |
+| Error             | Rapid all-blink → error code hold            | 5Hz for 1s, then code for 2s (3s cycle)   |
+| Moving / delays   | Waterfall 001→011→111→110→100→000            | ~1 cycle/s (167ms per step)               |
+| Calibrating       | All LEDs flash                               | 1Hz (500ms on / 500ms off)                |
+| Undo              | All LEDs solid on                            | Continuous                                |
+| Booting           | LED1 solid                                   | Until init complete                       |
+
+**Error code bits (during 2s hold phase):**
+
+| LED Pattern (bottom→top) | Meaning                                                |
+|--------------------------|--------------------------------------------------------|
+| 001 — only bottom (P05) lit | Efuse tripped (any bridge) or low battery           |
+| 010 — only middle (P06) lit | RTC/clock not set                                   |
+| 100 — only top (P07) lit    | Safety sensor break or leash limit hit              |
+| 111 — all three lit         | Unknown FSM error (fallback)                        |
+
+Error codes are also shown on the web interface status field with individual flag names.
+
+### Implementation Details
+
+- Tap detection uses **release edge** (`i2c_get_button_released()`) with `btn_held < 1000ms` guard (long presses don't count as taps)
+- 2-second tap window starts on first tap, fixed duration (not reset by subsequent taps)
+- All button state sampled once per tick: `btn_pressed`, `btn_tripped`, `btn_released`, `btn_held`
+
+---
+
+## Power Management
+
+- **Battery voltage:** GPIO35, thru divider → `V = raw × V_SENS_K + V_SENS_OFFSET` (defaults: K=0.00766̄, offset=0.4)
+- **Solar charger:** GPIO26 (RTC hold) — FLOAT/BULK FSM, bulk for 20s when V < 5V for 5s
+- **Inactivity shutdown:** 180s → **soft idle** (WiFi/BT off, LEDs off — not deep sleep). Button press exits soft idle.
+- **RTC_DATA_ATTR:** Sync timestamps, alarm times, charge state — survive software resets (panics, WDT)
+
+---
+
+## Error Codes (`sc_err.h`)
+
+```c
+SC_ERR_EFUSE_TRIP_1  = 0x201  // Drive overcurrent/overheat
+SC_ERR_EFUSE_TRIP_2  = 0x202  // Jack
+SC_ERR_EFUSE_TRIP_3  = 0x203  // Aux
+SC_ERR_SAFETY_TRIP   = 0x210  // Safety sensor break
+SC_ERR_LEASH_HIT     = 0x211  // Distance limit reached
+SC_ERR_RTC_NOT_SET   = 0x220  // Clock not synchronized
+SC_ERR_LOW_BATTERY   = 0x230  // Voltage below threshold
+```
+
+---
+
+## Build System
+
+- **Framework:** ESP-IDF (>=5.0)
+- **Component deps** (`main/idf_component.yml`): `espressif/mdns ~1.9.1`
+- **IDF requires:** `driver`, `esp_http_server`, `esp_netif`, `lwip`, `json`, `esp_timer`, `esp_adc`, `app_update`, `esp_wifi`, `nvs_flash`, `mdns`, `bt`, `esp_hid`
+- **Webpage:** `webpage.html` → `webpage_compile.py` → `webpage_gzip.h` (embedded gzip binary). **Must re-run `webpage_compile.py` after any HTML edit before building.**
+- **Version:** `version.h.in` filled by CMake from git tags → `FIRMWARE_VERSION`, `BUILD_DATE`

-		- the remaining_distance needs to be unaffected
-		- the equivalent of a try-catch block on the whole program
-		- this should also make a log
-- [ ] Logtool: python tool that shows logs
-		- needs to support both opening a log.bin and streaming from http://ip-address-or-hostname/log
-		- needs to have a CLI table output

+# Logtool Plan
+
+Python tool for viewing SC-F001 flash logs. Supports CLI table output, matplotlib GUI, and both file and HTTP sources.
+
+---
+
+## On-disk Entry Format
+
+Each entry in flash:
+```
+[len u8] [payload (len-1 bytes)] [type u8]
+```
+Total bytes per entry = `len + 1`.
+
+`log_write_blocking` does `len++` before writing, so `len` stored on disk = `payload_size + 1`, and `len - 1 = payload_size`. The write is correct and writes all payload bytes.
+
+Padding bytes (0x00 = sector padding, 0xFF = erased flash) cause the reader to skip to the next sector boundary.
+
+### Entry Types
+
+| Type  | Name     | Payload (bytes) | Stored len | Total on disk |
+|-------|----------|-----------------|------------|---------------|
+| 0–12  | FSM log  | 39              | 40         | 41            |
+| 100   | BAT log  | 12              | 13         | 14            |
+| 101   | CRASH    | 9               | 10         | 11            |
+
+All values **little-endian** (named `be_*` in source but no byte-swap — the names are misleading legacy).
+
+### FSM payload layout (39 bytes)
+```
+[0:8]   ts_ms      u64  — ms since epoch (local-as-UTC, no timezone)
+[8:12]  bat_V      f32  — battery voltage
+[12:16] drive_A    f32  — drive bridge raw current
+[16:20] jack_A     f32  — jack bridge raw current
+[20:24] aux_A      f32  — aux bridge raw current
+[24:26] counter    i16  — drive encoder counter (SENSOR_DRIVE)
+[26]    sensors    u8   — bits[3:0]=stable state, bits[7:4]=raw state
+                          bit position: SAFETY=0, JACK=1, DRIVE=2, AUX2=3
+[27:31] drive_heat f32  — e-fuse thermal accumulator, drive bridge
+[31:35] jack_heat  f32  — e-fuse thermal accumulator, jack bridge
+[35:39] aux_heat   f32  — e-fuse thermal accumulator, aux bridge
+```
+
+### BAT payload layout (12 bytes)
+```
+[0:8]  ts_ms  u64
+[8:12] bat_V  f32
+```
+
+### CRASH payload layout (9 bytes)
+```
+[0:8] ts_ms        u64
+[8]   reset_reason u8  — esp_reset_reason_t value
+```
+
+### FSM state names (from control_fsm.h — single source of truth)
+```
+0  = STATE_IDLE
+1  = STATE_MOVE_START_DELAY
+2  = STATE_JACK_UP_START
+3  = STATE_JACK_UP
+4  = STATE_DRIVE_START_DELAY
+5  = STATE_DRIVE
+6  = STATE_DRIVE_END_DELAY
+7  = STATE_JACK_DOWN
+8  = STATE_UNDO_JACK_START
+9  = STATE_CALIBRATE_JACK_DELAY
+10 = STATE_CALIBRATE_JACK_MOVE
+11 = STATE_CALIBRATE_DRIVE_DELAY
+12 = STATE_CALIBRATE_DRIVE_MOVE
+```
+
+---
+
+## HTTP /log Response Format
+
+```
+[4B json_len BE] [json_len bytes JSON] [4B tail_offset BE] [4B head_offset BE] [raw binary]
+```
+The raw binary is already linearized (tail→head wraparound handled server-side). Parse it sequentially as a stream of entries.
+
+**Streaming**: GET once to get the full log + current head, then POST with the current head as the tail to get only new entries. Repeat on a timer.
+
+---
+
+## File Format Auto-detection
+
+When opening a `.bin` file:
+1. Read first 4 bytes as BE uint32 → `candidate_json_len`
+2. If `candidate_json_len < 8192` AND byte at offset 4 is `{` → HTTP response format (parse header then binary)
+3. Otherwise → raw flash binary (skip header, parse binary directly from offset 0)
+
+---
+
+## Timestamps
+
+All timestamps are `ms since epoch` in **local-as-UTC** encoding: the device stores the user's local time directly as a Unix timestamp (no timezone offset). Display as-is using `datetime.utcfromtimestamp(ts_ms / 1000)` — no conversion needed.
+
+---

+### File layout
+```
+logtool/
+├── PLAN.md         ← this file
+├── logtool.py      ← main entry point (CLI + dispatch)
+├── parser.py       ← binary framing + struct unpack; reads state names from control_fsm.h
+├── source.py       ← file reader and HTTP fetcher (GET full, POST incremental)

+└── gui_view.py     ← matplotlib time-series charts
+```
+
+### `parser.py`
+- `load_fsm_states(fsm_h_path) -> dict[int, str]` — parses `control_fsm.h` to extract the `fsm_state_t` enum. Falls back to hardcoded dict if file not found.
+- `parse_entries(data: bytes) -> list[dict]` — iterates raw binary, skips padding (0x00/0xFF), unpacks each entry by type
+- `parse_response(blob: bytes) -> (dict, int, int, list[dict])` — parses full HTTP/file blob: json metadata, tail, head, entries
+
+### `source.py`
+- `read_file(path: str) -> bytes`
+- `fetch_full(url: str) -> bytes` — HTTP GET /log
+- `fetch_incremental(url: str, tail: int) -> (bytes, int)` — POST /log with tail as body, returns raw binary + new head
+- `stream(url: str, callback, interval_s=2.0)` — poll loop: GET once for full log, then POST repeatedly; calls `callback(new_entries, new_head)` each iteration
+
+### `cli_view.py`
+- `print_table(entries: list[dict], fsm_states: dict)` — tabulate output
+  - Columns: `time`, `type`, `state`, `bat_V`, `drive_A`, `jack_A`, `aux_A`, `counter`, `sensors_stable`, `sensors_raw`
+  - BAT/CRASH rows show only relevant columns; FSM-only columns shown as `—`
+  - CRASH rows prefixed with `***`
+- `print_summary(entries)` — time range, count by type, min/max battery
+
+### `gui_view.py`
+- `show_plots(entries: list[dict])` — matplotlib figure with subplots:
+  1. Battery voltage over time
+  2. Currents (drive, jack, aux) over time
+  3. FSM state over time (step/stairs plot)
+  4. Thermal accumulators (drive_heat, jack_heat, aux_heat)
+  - CRASH events: vertical red dashed lines across all subplots
+- `live_plot(url: str, interval_s=2.0)` — `FuncAnimation` + streaming source, updates all axes
+
+### `logtool.py` (CLI)

+## Resolved Questions
+
+1. **Entry size**: No bug. `len++` in `log_write_blocking` makes `len-1 = LOGSIZE = 39`, writing all payload bytes correctly.
+2. **Streaming**: GET for initial full fetch, then POST with current head as tail for incremental polling.
+3. **File format**: Auto-detect via 4-byte json_len + `{` check.
+4. **Timestamps**: local-as-UTC, display with `datetime.utcfromtimestamp()`, no conversion.
+5. **FSM state names**: Parse from `control_fsm.h` at startup (`--fw` flag or default `../main`). Fallback to hardcoded dict.
+6. **tabulate**: Acceptable dependency.

+# Logtool Debug Notes — 16 MAR 2026
+
+## Problem
+`storage-16MAR2026-1728.bin` not parsing correctly.
+
+## Root Cause (SOLVED)
+Two issues in `parser.py`:
+
+### 1. Unrecognized file format
+The file format is `[4B tail BE][4B head BE][raw log data]` — no JSON header.
+- `head - tail == file_size - 8` (the raw log data is exactly the flash region from tail to head)
+- The old HTTP format was: `[4B json_len BE][json][4B tail BE][4B head BE][raw log data]`
+- The parser's autodetect only recognized the old HTTP format (and required json_len < 8192)
+- **Fix:** Added detection for bare tail+head format in `autodetect_and_parse()`
+
+### 2. Type-first vs type-last detection failure
+The log entries use **type-first** format: `[len][type][payload]`
+But `_try_detect_type_first()` returned False because:
+- First entry had type=0x00 at both positions (ambiguous)
+- Timestamp was near-zero (RTC not yet set), so timestamp sanity check failed
+- Function gave up after only 1 entry (`break` at end of loop)
+- **Fix:** Loop over multiple entries (up to 200), added voltage sanity check (0.5-60V)
+
+## Verification
+- 54,831 entries parsed successfully
+- FSM states: IDLE (51169), JACK_UP (1078), DRIVE (994), etc.
+- Voltages: 3.3V–13.3V (reasonable for 3S LiPo system)
+- Timestamps: Jan 13 – Feb 6, 2026 (after RTC set)
+- Old HTTP-format .bin files still parse correctly
