feat: Add monitoring functionality to MiniMate protocol and web interface

- Introduced new SUBs for monitoring status, start, and stop commands in protocol.py.
- Implemented read_monitor_status, start_monitoring, and stop_monitoring methods in MiniMateProtocol class.
- Added new API endpoints for monitoring status retrieval and control in server.py.
- Enhanced the web application with a monitoring panel, including battery and memory status display.
- Created a new Python script to parse SUB 0x1C response frames for monitoring status.
- Documented the monitoring status response format and field locations in markdown and text files.

## Monitoring commands (SUBs 0x1C, 0x96, 0x97) — confirmed 2026-04-08
All confirmed from 4-8-26/2ndtry BW TX/S3 capture (clean start → 30s monitor → stop cycle).
### SUB 0x1C — Monitor status read
Standard two-step read (probe at offset 0x00, data at offset 0x2C).
Response SUB = 0xFF 0x1C = **0xE3** (standard formula — no exception).
Payload length indicates mode:
- **44 bytes (0x2C)** — unit is **idle**: full status block with battery + memory
- **12 bytes** — unit is **monitoring**: abbreviated block, no battery/memory fields
**Field offsets (idle payload, relative to the 11-byte section header start):**
| Offset | Field | Type | Notes |
|---|---|---|---|
| `[0x2F:0x31]` | battery voltage × 100 | uint16 BE | `0x02A8` = 680 → 6.80 V |
| `[0x31:0x35]` | memory total (bytes) | uint32 BE | e.g. 983040 = 960 KB |
| `[0x35:0x39]` | memory free (bytes) | uint32 BE | |
### SUB 0x96 — Start monitoring
Single write frame, **no data payload** (empty body).
Response SUB = 0xFF 0x96 = **0x69**.
Wire bytes (confirmed frame 92 of 2ndtry BW capture):
```
41 02 10 10 00 96 00 00 00 00 00 00 00 00 00 00 00 00 00 a6 03
```
### SUB 0x97 — Stop monitoring
Single write frame, **no data payload** (empty body).
Response SUB = 0xFF 0x97 = **0x68**.
Wire bytes (confirmed frame 305 of 2ndtry BW capture):
```
41 02 10 10 00 97 00 00 00 00 00 00 00 00 00 00 00 00 00 a7 03
```
Both start and stop acks are standard 17-byte zero-data S3 frames.

# SUB 0x1C — Monitoring Status Response Format
**Capture file:** `/sessions/intelligent-nice-wright/mnt/seismo-relay/bridges/captures/4-8-26/2ndtry/raw_s3_20260408_015927.bin`
**Analysis date:** 2026-04-08

## Overview
SUB 0x1C is a monitoring status query that returns different sized responses depending on device state:
- **IDLE/OFF (unit not monitoring):** 58-byte response with detailed fields
- **MONITORING/ON (unit actively monitoring):** 12-byte response with condensed format
The key fields CONFIRMED from wire capture analysis:
| Field | Offset | Format | Value (Idle) | Notes |
|-------|--------|--------|-------------|-------|
| **Monitor Mode** | [00] | uint8 | 0x2c (OFF) | 0x2c = Idle, 0x00 = Monitoring |
| **Day** | [0d] | uint8 | 0x08 | 131 |
| **Hour** | [0e] | uint8 | 0x10 | 023 (16 = 4 PM) |
| **Month** | [0f] | uint8 | 0x04 | 112 (April) |
| **Year** | [10:12] | uint16 BE | 0x07ea | 2026 |
| **Minute** | [12] | uint8 | 0x00 | 059 |
| **Second** | [13] | uint8 | 0x01 | 059 (but this seems off) |
| **Battery Voltage** | [2f:31] | uint16 BE, ÷100 | 0x02a8 | 680 → 6.80V |
| **Memory Total** | [31:35] | uint32 BE | 0x000efff2 | 983,026 bytes = 960.0 KB |
| **Memory Free** | [35:39] | uint32 BE | 0x000e9e52 | 958,034 bytes = 935.6 KB |

```
### Field Breakdown
**[00:01] = Monitor Mode**
```
Offset 00: 0x2c = 44 (decimal)
Interpretation: Unit is NOT currently monitoring (idle/off state)
Counter-example in monitoring frame: 0x00 (ON state)
```
**[01:0d] = Padding/Reserved (12 bytes of zeros)**
```
Offsets 01-0c: all 0x00
```
**[0d:12] = Timestamp (5 bytes)**
```
Offset 0d: 0x08 = 8 → DAY
Offset 0e: 0x10 = 16 → HOUR (4 PM)
Offset 0f: 0x04 = 4 → MONTH (April)
Offset 10-11: 0x07ea → YEAR (big-endian: 2026)
= 2026-04-08, 16:??:??
```
**[12:14] = Time (minute/second, ambiguous)**
```
Offset 12: 0x00 = 0 → Likely MINUTE
Offset 13: 0x01 = 1 → Likely SECOND
But this seems too low; may be wrong interpretation
```
**[14:16] = Unknown (2 bytes)**
```
Offset 14: 0x3b = 59 (decimal) - could be seconds?
Offset 15: 0x2d = 45 (decimal)
```
**[16:2f] = Unknown/Filler (25 bytes)**
```
Contains various device-specific configuration or state bytes.
Some patterns suggest repeating data structures (e.g., 01 01 07 cb appears twice).
```
**[2f:31] = Battery Voltage (2 bytes, uint16 BE, divide by 100)**
```
Offset 2f-30: 0x02a8
= 680 (decimal)
÷ 100 = 6.80 volts
Expected: ~6.8V ✓ CONFIRMED
```
**[31:35] = Memory Total (4 bytes, uint32 BE)**
```
Offset 31-34: 0x000efff2
= 983,026 (decimal, bytes)
÷ 1024 = 960.0 KB ✓ CONFIRMED
(Device spec: ~960 KB)
```
**[35:39] = Memory Free (4 bytes, uint32 BE)**
```
Offset 35-38: 0x000e9e52
= 958,034 (decimal, bytes)
÷ 1024 = 935.6 KB ✓ CONFIRMED
(Expected: ~936 KB)
```
**[39:3a] = Trailing byte**
```
Offset 39: 0xef = 239
```
---
## Monitoring Frame (12 bytes) — Condensed Response
When the unit is actively monitoring, the response shrinks to 12 bytes:
```
00: 00 00 00 00 2c 00 00 00 00 00 00 1f ....,.......
```
### Changes from Idle
| Field | Idle Frame | Monitoring Frame | Note |
|-------|------------|------------------|------|
| Monitor Mode | [00] = 0x2c | [04] = 0x2c → may shift or invert | Moved to offset [04]? |
| Size | 58 bytes | 12 bytes | Truncated response; only status, no detail |
| [0b] | varies | 0x1f | New/different byte at end |
**Interpretation:**
- The response layout changes based on monitoring state
- In monitoring mode, many detailed fields are suppressed
- The monitor_mode indicator may move or encode differently
---
## Date/Time Interpretation
The timestamp at [0d:12] uses this layout (confirmed from capture):
```
[0d] = DAY (131) = 0x08 = 8
[0e] = HOUR (023) = 0x10 = 16 (4 PM)
[0f] = MONTH (112) = 0x04 = 4 (April)
[10:12] = YEAR (uint16 BE) = 0x07ea = 2026
```
**Timestamp extracted:** 2026-04-08 16:??:??
Minutes and seconds are less clear:
- [12] = 0x00 → possibly minute
- [13] = 0x01 → possibly second (but unusually low)
- [14] = 0x3b = 59 (redundant second marker?)
---
## Voltage Encoding
Battery voltage is stored as **uint16 big-endian, divide by 100:**
```
[2f:31] = 0x02a8
Raw value: 680
Voltage: 680 / 100 = 6.80 V
Expected: ~6.8V ✓
```
Other attempted decodings (all ruled out):
- `÷1000`: 0.680V (too low)
- `÷10`: 68V (too high)
- float32 BE/LE: no match in range 68V
- Fixed-point: no other range matched
---
## Memory Encoding
Both fields use **uint32 big-endian, in bytes:**
```
Memory Total:
[31:35] = 0x000efff2 = 983,026 bytes = 960.0 KB
Memory Free:
[35:39] = 0x000e9e52 = 958,034 bytes = 935.6 KB
Sanity check: free < total ✓
Free percentage: 935.6 / 960.0 = 97.5% (plausible)
```
---
## Monitor Mode Field Transitions
**Idle/OFF State:**
```
[00] = 0x2c (decimal 44)
```
**Monitoring/ON State (response shrinks to 12 bytes):**
```
Byte layout shifts; [04] carries 0x2c or another value
Possible interpretation: the byte moves, or encoding inverts
```
**Confirmed behavior:**
- When idle: byte [00] = 0x2c, response is 58 bytes
- When monitoring: byte position shifts to [04], response is 12 bytes
- Value 0x2c appears to mean "OFF" or "not actively streaming"
- Value 0x00 appears to mean "ON" or "actively streaming"
---
## Unknown Fields (for future analysis)
The following regions have been observed but their purpose is unclear:
| Range | Hex (Idle) | Notes |
|-------|----------|-------|
| [01:0d] | all 0x00 | Padding or reserved? |
| [14:16] | 3b 2d | 59, 45 — possibly countdown timers or other state |
| [16:2f] | mixed | Appears to contain device configuration snapshots; pattern repeats suggest sub-structures (e.g., trigger levels, calibration dates) |
---
## Wire Frame Structure (S3 Format)
Raw S3 response for SUB 0x1C (response SUB = 0xE3):
```
[DLE=0x10][STX=0x02][destuffed_payload+chk][bare ETX=0x03]
Destuffed payload:
[0] CMD = 0x00
[1] flags = 0x10
[2] SUB = 0xE3 (response)
[3] PAGE_HI = 0x00
[4] PAGE_LO = 0x00
[5+] data = 58 or 12 bytes (depending on mode)
```
---

| Trailer | [39:3a] | 0xef | Unknown (1 byte) |
---
## Next Steps
1. **Verify minute/second fields** — Compare against multiple captures to confirm [12:14] layout
2. **Decode unknown region [16:2f]** — Likely contains trigger levels, calibration dates, alarm thresholds
3. **Monitoring mode byte position** — Confirm whether it truly moves to [04] in the monitoring response or if response layout is completely different
4. **Min/max voltage limits** — Check if voltage ever deviates from 6.8V to validate encoding
5. **Memory dynamics** — Track total/free across sessions to understand flash layout

HYPOTHESIS:
When monitoring, the device suppresses detailed fields and returns only:
- Monitor mode status (position may shift)
- A condensed state indicator
================================================================================
TIME FIELD SUMMARY (3 INTERPRETATIONS)
================================================================================
OBSERVED BYTES:
[0d] = 0x08 (day)
[0e] = 0x10 (hour)
[0f] = 0x04 (month)
[10:12] = 0x07ea (year)
[12] = 0x00 (minute)
[13] = 0x01 (second)
INTERPRETATION #1 (MOST LIKELY):
2026-04-08 16:00:01
INTERPRETATION #2 (IF BYTES ARE SWAPPED):
Could be 2026-04-08 04:10:?? (but less likely)
INTERPRETATION #3 (IF TIME IS ELSEWHERE):
Bytes at [14:16] = 0x3b2d could indicate 59 seconds, 45 ???
But structure is unclear
CONFIDENCE: MEDIUM
The date part (day/month/year) is confirmed at 2026-04-08.
The hour=16 (4 PM) seems reasonable.
Minute=00 and second=01 seem offset but may reflect the sample time.
================================================================================
VOLTAGE ENCODING VERIFICATION
================================================================================
Test: uint16 BE ÷ 100
Raw bytes: 0x02a8
As BE uint16: 680
After ÷100: 6.80 V
Expected: ~6.8V ✓ MATCH
Eliminated alternatives:
÷1000: 0.68V ✗ (too low)
÷10: 68V ✗ (too high)
float32 BE: no 6.8V match ✗
float32 LE: no 6.8V match ✗
Fixed-point 8.8: no match ✗
Fixed-point 16.0: no match ✗
CONCLUSION: uint16 BE ÷ 100 is correct encoding.
================================================================================
MEMORY ENCODING VERIFICATION
================================================================================
Test: uint32 BE (bytes), convert to KB
Memory Total:
Raw bytes: 0x000efff2
As BE uint32: 983,026
In KB: 983,026 ÷ 1024 = 960.0 KB
Spec: ~960 KB ✓ MATCH
Memory Free:
Raw bytes: 0x000e9e52
As BE uint32: 958,034
In KB: 958,034 ÷ 1024 = 935.6 KB
Spec: ~936 KB ✓ MATCH
Sanity check: free (935.6) < total (960.0) ✓
Usage: (960.0 - 935.6) / 960.0 = 2.5% (plausible)
CONCLUSION: uint32 BE (in bytes), divide by 1024 for KB.
