+# Claude Code slash commands for the mcp-server test suite
+
+Three AI-assisted workflows wrapping `mcp-server/run-tests.sh` and the meshtastic MCP tools. Each one has a twin in `.github/prompts/` for Copilot users.

+| `/repro <test> [n=5]` | Re-runs one test N times, diffs firmware logs between passes and failures | `.github/prompts/mcp-repro.prompt.md`    |
+
+## Why two surfaces
+
+The Claude Code commands and Copilot prompts cover the same three workflows but each speaks its host's idiom:
+
+- **Claude Code** (`/test`) uses `$ARGUMENTS` for pass-through, has direct access to Bash + all MCP tools registered in the user's settings, and runs in the terminal context.
+- **Copilot** (`/mcp-test`) runs in VS Code's agent mode; it has terminal + MCP access too but typically asks the operator to confirm inputs interactively.
+
+A contributor using either IDE gets equivalent assistance. Keep the two in sync when behavior changes — the diff of intent should be minimal.
+
+## House rules
+
+- **No destructive writes without explicit operator approval.** Skills that could reflash, factory-reset, or reboot a device must describe the action and stop — the operator authorizes.
+- **Interpret failures, don't just echo them.** The skill body should pull firmware log lines from `mcp-server/tests/report.html` (the `Meshtastic debug` section, attached by `tests/conftest.py::pytest_runtest_makereport`) and classify the failure.
+- **Keep MCP tool calls sequential per port.** SerialInterface holds an exclusive port lock; two parallel tool calls on the same port deadlock.
+- **Never speculate about root cause.** If the evidence doesn't support a classification, say "unknown" and list what you'd need to disambiguate.

+## Adding a new command
+
+1. Write the Claude Code version at `.claude/commands/<name>.md` with YAML frontmatter:
+
+   ```yaml
+   ---
+   description: one-line purpose (used for auto-invocation by the model)
+   argument-hint: [optional-hint]

+2. Write the Copilot equivalent at `.github/prompts/mcp-<name>.prompt.md` with:
+
+   ```yaml
+   ---
+   mode: agent
+   description: ...
+   ---
+   ```
+
+3. Add the row to the table above. Cross-link in both bodies.
+
+4. Smoke-test on Claude Code first (`/<name>` should appear in autocomplete), then in VS Code Copilot (`/mcp-<name>` in Chat).

+description: Produce a device health report using the meshtastic MCP tools (device_info, list_nodes, get_config, short serial log capture)
+argument-hint: [role=all|nrf52|esp32s3|<port>]
+---
+
+# `/diagnose` — device health report
+
+Call the meshtastic MCP tool bundle and format a structured health report for one or all detected devices. Zero guesswork for the operator.
+
+## What to do
+
+1. **Enumerate hardware.** Call `mcp__meshtastic__list_devices(include_unknown=True)`. For each entry where `likely_meshtastic=True`, capture `port`, `vid`, `pid`, `description`.
+
+2. **Filter by `$ARGUMENTS`**:
+   - No args, `all` → every likely-meshtastic device.
+   - `nrf52` → only devices with `vid == 0x239a`.
+   - `esp32s3` → only devices with `vid == 0x303a` or `vid == 0x10c4`.
+   - A `/dev/cu.*` path → only that one port.
+   - Anything else → treat as a substring match against the `port` string.
+
+3. **For each selected device, in sequence (NOT parallel — SerialInterface holds an exclusive port lock):**
+   - `mcp__meshtastic__device_info(port=<p>)` — captures `my_node_num`, `long_name`, `short_name`, `firmware_version`, `hw_model`, `region`, `num_nodes`, `primary_channel`.
+   - `mcp__meshtastic__list_nodes(port=<p>)` — count of peers, which ones have `publicKey` set, SNR/RSSI distribution.
+   - `mcp__meshtastic__get_config(section="lora", port=<p>)` — region, preset, channel_num, tx_power, hop_limit.
+   - Optionally, if the device seems unhappy (fails to connect, `num_nodes==1` when ≥2 are plugged in, missing firmware*version), open a short firmware log window: `mcp__meshtastic__serial_open(port=<p>, env=<inferred-env>)`, wait 3s, `serial_read(session_id=<s>, max_lines=100)`, `serial_close(session_id=<s>)`. The env should be inferred from the VID map in `mcp-server/run-tests.sh` (nrf52 → rak4631, esp32s3 → heltec-v3) unless `MESHTASTIC_MCP_ENV*<ROLE>` is set.
+
+4. **Hub health** (call once, not per-device): `mcp__meshtastic__uhubctl_list()` — enumerates every USB hub the host can see. Note which hubs advertise `ppps=true` and which hub hosts each Meshtastic device (cross-reference by VID). Flag it in the report if:
+   - No hub advertises PPPS → `tests/recovery/` can't run on this setup; hard-recovery via `uhubctl_cycle` isn't available.
+   - A Meshtastic device is on a non-PPPS hub → note it; operator may want to move the device to a PPPS hub to unlock auto-recovery.
+   - `uhubctl_list` raises `ConfigError: uhubctl not found` → just say `uhubctl not installed` in the report; don't treat as a fault.
+
+5. **Render per-device report** as:
+
+   ```text
+   [nrf52 @ /dev/cu.usbmodem1101]      fw=2.7.23.bce2825, hw=RAK4631
+     owner       : Meshtastic 40eb / 40eb
+     region/band : US, channel 88, LONG_FAST
+     tx_power    : 30 dBm, hop_limit=3
+     peers       : 1 (esp32s3 0x433c2428, pubkey ✓, SNR 6.0 / RSSI -24 dBm)
+     primary ch  : McpTest
+     hub         : 1-1.3 port 2 (PPPS, uhubctl-controllable)
+     firmware    : no panics in last 3s; NodeInfoModule emitted 2 broadcasts
+   ```
+
+   Keep it scannable. If a field is missing or abnormal (no pubkey for a known peer, region=UNSET, num_nodes inconsistent with the hub, device on non-PPPS hub), flag it inline with a short `⚠︎ <one-line reason>`.
+
+6. **Cross-device correlation** (only when >1 device is inspected):
+   - Do both sides see each other in `nodesByNum`? If one does and the other doesn't, that's asymmetric NodeInfo — flag it.
+   - Do the LoRa configs match? (region, channel_num, modem_preset should all agree; mismatch = no mesh)
+   - Do the primary channel NAMES match? Mismatch = different PSK = no decode.
+
+7. **Recorder slice (cheap, always available).** The mcp-server runs an autouse log recorder that's been collecting from every connected device. Pull two short slices to surface anything weird that's already happened:
+   - `mcp__meshtastic__logs_window(start="-2m", level="WARN|ERROR|CRIT", max_lines=20)` — recent firmware errors. If empty, say "no recent errors"; don't manufacture concern.
+   - `mcp__meshtastic__telemetry_timeline(window="1h", field="free_heap", max_points=60)` — heap trend. If `slope_per_min < -50`, flag it and recommend `/leakhunt window=6h` for a deeper read; otherwise just note the current free heap.
+   - If `recorder_status` shows `running:false` or `files.telemetry.last_ts` is null, note "recorder has no telemetry yet — enable `set_debug_log_api(True)` to populate" and skip this step gracefully.
+
+8. **Suggest next actions only for specific, recognisable failure modes**:
+   - Stale PKI pubkey one-way → "run `/test tests/mesh/test_direct_with_ack.py` — the retry + nodeinfo-ping heals this in the test path."
+   - Region mismatch → "re-bake one side via `./mcp-server/run-tests.sh --force-bake`."
+   - Device unreachable, reachable via DFU → `touch_1200bps(port=...)` + `pio_flash`. If not even DFU responds AND the device is on a PPPS hub, escalate to `uhubctl_cycle(role=..., confirm=True)`.
+   - CP2102-wedged-driver on macOS → see the note in `run-tests.sh`.
+   - Heap slope strongly negative → "run `/leakhunt window=6h` for a full timeline + classification."
+
+## What NOT to do
+
+- No writes. No `set_config`, no `reboot`, no `factory_reset`. This is a read-only diagnostic skill — if the operator wants to change state, they'll ask explicitly.
+- No `flash` / `erase_and_flash`. Those are separate escalations.
+- No holding SerialInterface across tool calls — open, query, close; next device. The port lock is exclusive.

+description: Hunt for memory leaks (and other slow degradations) by reading the persistent recorder's heap timeline + log slice over a window
+argument-hint: [window=1h] [field=free_heap] [variant=local]
+---
+
+<!-- markdownlint-disable MD029 -->
+
+# `/leakhunt` — read the recorder, classify a memory leak
+
+Use the always-on recorder (`mcp-server/.mtlog/`) to read a heap timeline plus the matching log slice and produce a one-page verdict: **steady / slow leak / fragmentation / OOM-imminent**. No firmware changes, no special build flags — the LocalStats telemetry packet that the firmware already broadcasts every ~60 s carries `heap_free_bytes` and `heap_total_bytes`.
+
+## Two signal paths — pick the right one
+
+| Path                  | Build flag       | Cadence        | Per-thread attribution | Cost                      |
+| --------------------- | ---------------- | -------------- | ---------------------- | ------------------------- |
+| LocalStats packet     | (default)        | ~60 s          | No                     | Free — always on          |
+| `[heap N]` log prefix | `-DDEBUG_HEAP=1` | every log line | Yes (Thread X leaked)  | Bigger flash + log volume |
+
+Both feed the same `telemetry_timeline(field="free_heap")` query — when DEBUG_HEAP is on, the recorder synthesizes telemetry rows from log prefixes (tagged `source: debug_heap`), so a single timeline call gets whichever signal is available. **For a slow leak diagnosis, the default path is plenty** (60 s cadence over 6 h = 360 points; linear regression over that nails sub-100-byte/min slopes). **DEBUG_HEAP is for attribution** — when the slope is real and you need to know which thread is leaking.
+
+## What to do
+
+1. **Parse `$ARGUMENTS`**: optional `window` (default `1h`, accepts `30m`/`6h`/`-3d`/etc.), optional `field` (default `free_heap`; alternates: `total_heap`, `battery_level`, anything in the LocalStats variant), optional `variant` (default `local`; alternates: `device`, `environment`, `power`, `airQuality`, `health`).
+
+2. **Verify the recorder is alive** — call `mcp__meshtastic__recorder_status`. Check:
+   - `running == True`
+   - `files.telemetry.lines > 0` (at least one telemetry packet recorded — if zero, the device hasn't broadcast LocalStats yet OR `set_debug_log_api` has never been on; tell the operator to run `mcp__meshtastic__set_debug_log_api(enabled=True)` and wait one device-update interval)
+   - `files.telemetry.last_ts` within the last 5 minutes (if older, the device is silent — log that, not "leak detected")
+
+3. **Detect whether DEBUG_HEAP is active** — `mcp__meshtastic__logs_window(start="-2m", grep=r"\\[heap \\d+\\]", max_lines=3)`. If any line matches, the firmware has the prefix → DEBUG_HEAP is on, expect higher-cadence data and `heap_event` rows. If zero matches over the last 2 minutes, you're on the LocalStats-only path.
+
+4. **Pull the timeline** — `mcp__meshtastic__telemetry_timeline(window=$window, variant=$variant, field=$field, max_points=200)`. Read:
+   - `samples` — how many raw points contributed
+   - `min`, `max` — total swing
+   - `slope_per_min` — units per minute (linear regression over the whole window)
+
+5. **Pull the log context for the same window** — `mcp__meshtastic__logs_window(start="-${window}", grep="Heap status|leaked heap|freed heap|out of memory|Alloc an err|panic|abort", max_lines=200)`. These are the strings the firmware emits when something memory-related happens (`DEBUG_HEAP` builds emit `"Heap status:"` and `"leaked heap"` lines; production builds emit `"Alloc an err"` on failure and `"out of memory"` on OOM).
+
+6. **Pull marker events** so we know if the operator labeled phases — `mcp__meshtastic__events_window(start="-${window}", kind="mark|connection_lost|connection_established")`. If a `connection_lost` overlaps a sharp drop, that's not a leak; that's a reboot.
+
+6a. **(DEBUG_HEAP only) Per-thread attribution** — `mcp__meshtastic__logs_window(start="-${window}", grep="leaked heap", max_lines=200)`. Each row has a structured `heap_event` field with `{kind, thread, before, after, delta}`. Aggregate by thread: sum the `delta` over the window per thread name. The thread with the largest cumulative negative delta is your suspect. Note the count too — a thread with 50× small leaks is different from 1× big leak.
+
+7. **Classify** based on what the data says, NOT on what you wish it said. Use these rules in order:
+   - **Insufficient data** (< 5 samples): say so. Suggest a longer window or longer wait. Stop.
+   - **Reboot mid-window**: if any `connection_lost` event is present AND `free_heap` jumped UP at that timestamp, the device rebooted. Note it; pre-reboot trend may be a leak but you only have part of the curve.
+   - **OOM-imminent**: any `Alloc an err=` or `out of memory` line in the log slice. This trumps everything; flag urgently.
+   - **Slow leak**: `slope_per_min < -50` AND `max - min > 1000` AND no reboot. The heap is monotonically (or near-monotonically) declining. Estimate time-to-zero: `min / -slope_per_min` minutes. Surface it.
+   - **Fragmentation suspect**: `slope_per_min` close to zero (|x| < 50) BUT min trends down across the window AND the log slice shows `Alloc an err` warnings WITHOUT total OOM. Means free total is OK but largest contiguous block is shrinking. Recommend a `DEBUG_HEAP` build to confirm.
+   - **Steady**: |slope_per_min| < 50, no error lines. Heap is fine.
+   - **Recovery curve**: slope is POSITIVE — heap recovered. Either a workload completed or GC fired. Note it; not a leak.
+
+8. **Report**:
+
+   ```text
+   /leakhunt window=6h field=free_heap variant=local
+   ────────────────────────────────────────────────────
+   recorder        : running, telem last_ts 8s ago

+   est. time-to-OOM: ~1,127 min (~18.8 h) at current slope
+   evidence        : (3 log line citations with uptimes)
+   ```
+
+   Then: **what to do next.**
+   - SLOW LEAK, **DEBUG_HEAP off** → recommend rebuilding with the flag and re-running this skill. Concrete one-liner the operator can copy:
+     ```text
+     mcp__meshtastic__build(env="<env>", build_flags={"DEBUG_HEAP": 1})
+     mcp__meshtastic__pio_flash(env="<env>", port="<port>", confirm=True)
+     ```
+     After flash, set debug_log_api back on and wait one window; re-run `/leakhunt`.
+   - SLOW LEAK, **DEBUG_HEAP on** → cite the top-leaking thread name from step 6a. Point at the corresponding source file (`grep -rn "ThreadName(\"<name>\")" src/`); the operator decides what to fix.
+   - FRAGMENTATION SUSPECT → propose pre-allocating any per-packet buffers; or rebuilding with `CONFIG_HEAP_TASK_TRACKING=y` on ESP32 to see who's holding the largest blocks.
+   - OOM-IMMINENT → flag for immediate attention; don't wait for the next telemetry interval.
+   - STEADY → say so; stop. Don't invent problems.
+
+## What NOT to do
+
+- Don't assume a leak from a single dip. LocalStats fires every ~60 s and the firmware naturally allocates+frees on each broadcast cycle; one packet sees the trough. Look at the slope, not the deltas.
+- Don't recommend code changes. This skill diagnoses; the operator decides what to fix.
+- Don't enable `set_debug_log_api` automatically — if it's off, telemetry isn't reaching pubsub anyway, and the recorder will be empty. Tell the operator to flip it on and wait, then re-run.
+- Don't run heavy workloads to "trigger the leak." The recorder is passive; we read what's there.
+
+## Companion: `mark_event` for stress runs
+
+If the operator wants to test under stimulus (e.g. blast 50 broadcasts and see what the heap does), they can frame the experiment with markers:
+
+```text
+mark_event("burst-start")
+… run the workload …
+mark_event("burst-end")
+/leakhunt window=15m
+```
+
+The markers land in both `events.jsonl` and `logs.jsonl`, so the report can show "free_heap dipped 8 KB during the burst window, recovered to baseline within 2 LocalStats cycles" → not a leak.

+description: Re-run a specific test N times in isolation to triage flakes, diff firmware logs between passes and failures
+argument-hint: <test-node-id> [count=5]
+---
+
+<!-- markdownlint-disable MD029 -->
+
+# `/repro` — flakiness triage for one test
+
+Re-run a single pytest node ID N times in isolation, track pass rate, and surface what's _different_ in the firmware logs between the passing attempts and the failing ones. Turns "it's flaky, I guess" into "it fails when X, passes when Y."
+
+## What to do
+
+1. **Parse `$ARGUMENTS`**: first token is the pytest node id (e.g. `tests/mesh/test_direct_with_ack.py::test_direct_with_ack_roundtrip[nrf52->esp32s3]`); second token is an integer count (default `5`, cap at `20`). If the first token doesn't look like a test path (no `::` and no `tests/` prefix), treat the whole `$ARGUMENTS` as a `-k` filter instead.
+
+2. **Sanity-check the hub first** (so we're not measuring "nothing plugged in" N times): call `mcp__meshtastic__list_devices`. If the test name contains `nrf52` or `esp32s3` and the matching VID isn't present, stop and report — re-running won't help.
+
+3. **Loop N times**. For each iteration:
+
+   ```bash
+   ./mcp-server/run-tests.sh <test-id> --tb=short -p no:cacheprovider
+   ```
+
+   Capture: exit code, duration, and (on failure) the `Meshtastic debug` firmware log section from `mcp-server/tests/report.html`. `-p no:cacheprovider` suppresses pytest's `.pytest_cache` writes so iterations don't influence each other.
+
+4. **Track a small structured tally**:
+
+   ```text
+   attempt 1: PASS (42s)
+   attempt 2: FAIL (128s)  ← firmware log 200-line tail captured
+   attempt 3: PASS (39s)
+   attempt 4: FAIL (121s)
+   attempt 5: PASS (41s)
+   --------------------------------------
+   pass rate: 3/5 (60%)   |   mean duration: 74s
+   ```
+
+5. **On mixed outcomes**: diff the firmware log tails between a representative passing attempt and a representative failing attempt. Focus on:
+   - Error-level lines only present in failures (`PKI_UNKNOWN_PUBKEY`, `Alloc an err=`, `Skip send`, `No suitable channel`)
+   - Timing around the assertion event — did a broadcast go out, was there an ACK, did NAK fire?
+   - Device state fields that changed (nodesByNum entries, region/preset, channel_num)
+
+   Surface the top 3 differences as a "passes when / fails when" table. Don't dump full logs — pull specific lines with uptime timestamps.
+
+5a. **Archive recorder slices per attempt** (no extra device interaction; the recorder runs autouse). Right after each attempt finishes, capture its `(start_ts, end_ts)` and call `mcp__meshtastic__recorder_export(start=<start>, end=<end>, dest_dir="mcp-server/tests/repro_artifacts/<safe-test-id>/attempt_<n>/")`. This drops a `logs.jsonl`, `telemetry.jsonl`, `packets.jsonl`, and `events.jsonl` snapshot scoped to the attempt window. Use these for cross-attempt diffs in step 5: `jq '.line' logs.jsonl` is faster than re-running the test, and the telemetry slice lets you compare heap behavior across attempts.
+
+6. **Classify the flake** into one of:
+   - **LoRa airtime collision** → pass rate improves with fewer concurrent transmitters; propose a `time.sleep` gap or retry bump in the test body.
+   - **PKI key staleness** → fails on first attempt, passes after self-heal; existing retry loop in `test_direct_with_ack.py` handles this.
+   - **NodeInfo cooldown** → `Skip send NodeInfo since we sent it <600s ago` in fail-only logs; needs `broadcast_nodeinfo_ping()` warmup.
+   - **Hardware-specific** (one direction fails, other passes; one device's firmware is older; driver wedged) → specific recovery pointer. For a device that's wedged past `touch_1200bps`, the next escalation is `uhubctl_cycle(role=..., confirm=True)` to hard-power-cycle its hub port (requires `uhubctl` installed).
+   - **Device went dark mid-run** → fails from some attempt onward, never recovers, firmware log stops arriving. Almost always hardware: a Guru crash + frozen CDC. Hard-power-cycle via `uhubctl_cycle(role=..., confirm=True)` before the next iteration; if that also fails, escalate to replug.
+   - **Genuinely unknown** → say so; don't invent a root cause.
+
+7. **Report back** with:
+   - Pass rate and mean duration.
+   - Classification + evidence (the specific log lines that support it).
+   - A suggested next step (re-run with specific args, open `/diagnose`, edit a specific test file, nothing).
+
+## Examples
+
+- `/repro tests/mesh/test_direct_with_ack.py::test_direct_with_ack_roundtrip[esp32s3->nrf52] 10` — runs 10 times, diffs firmware logs.
+- `/repro broadcast_delivers` — no `::`, no `tests/`, so interpreted as `-k broadcast_delivers`; runs every matching test the default 5 times.
+- `/repro tests/telemetry/test_device_telemetry_broadcast.py 3` — shorter run for a slow test.
+
+## Constraints
+
+- Don't exceed `count=20` per invocation — airtime and USB wear add up. If the user asks for 50, negotiate down.
+- Don't rebuild firmware as part of triage; flakes that only reproduce under different firmware belong in a separate session.
+- If the FIRST attempt fails AND the rest all pass, that's a classic "state leak from a prior test" → say so and suggest running with `--force-bake` or starting from a clean state rather than chasing the first failure.

+
+Run `mcp-server/run-tests.sh` and make sense of the output so the operator doesn't have to.
+
+## What to do
+
+1. **Invoke the wrapper.** From the firmware repo root, run:
+
+   ```bash
+   ./mcp-server/run-tests.sh $ARGUMENTS
+   ```
+
+   The wrapper auto-detects connected Meshtastic devices, maps each to its PlatformIO env, exports the required `MESHTASTIC_MCP_ENV_*` env vars, and invokes pytest. If the user passed no arguments, the wrapper supplies a sensible default set (`tests/ --html=tests/report.html --self-contained-html --junitxml=tests/junit.xml -v --tb=short`). A `--report-log=tests/reportlog.jsonl` arg is always appended (unless the operator passed their own). `--assume-baked` is deliberately NOT in the defaults — `test_00_bake.py` has its own skip-if-already-baked check and runs the ~8 s verification by default. Operators can opt into the fast path with `--assume-baked`, or force a reflash with `--force-bake`.
+
+2. **Read the pre-flight header.** First ~6 lines print the detected hub (role → port → env). If that line reads `detected hub : (none)`, the wrapper will narrow to `tests/unit` only — say so explicitly in your summary so the operator knows hardware tiers were skipped.

+3. **On pass**: one-line summary of the form `N passed, M skipped in <duration>`. Don't enumerate the test names — the user can read those. Do mention any SKIPPED tests and name the cause:
+   - `"role not present on hub"` → device unplugged; operator knows to reconnect.
+   - `"firmware not baked with USERPREFS_UI_TEST_LOG"` → tests/ui skipped because the macro isn't in firmware yet; suggest `--force-bake`.
+   - `"uhubctl not installed"` → tests/recovery + peer-offline skipped; suggest `brew install uhubctl` / `apt install uhubctl`.
+   - `"no PPPS-capable hubs detected"` → tests/recovery skipped because the hub doesn't support per-port power; the tier will never run on that setup.
+   - `"opencv-python-headless is not installed"` → tests/ui auto-deselected by run-tests.sh; suggest `pip install -e 'mcp-server/.[ui]'`.
+
+4. **On failure**: for every FAILED test, open `mcp-server/tests/report.html` and extract the `Meshtastic debug` section for that test. pytest-html embeds the firmware log stream + device state dump there; the 200-line firmware log tail is usually enough to explain the failure. Summarise: which test, one-line assertion message, the firmware log lines that matter (things like `PKI_UNKNOWN_PUBKEY`, `Skip send NodeInfo`, `Error=`, `Guru Meditation`, `assertion failed`). For UI-tier failures also glance at `mcp-server/tests/ui_captures/<session>/<test>/transcript.md` — it records each step's frame + OCR.
+
+5. **Classify the failure** as one of:
+   - **Transient/flake**: LoRa collision, timing-sensitive assertion, first-attempt NAK + successful retry pattern. Propose `/repro <test_node_id>` to confirm.
+   - **Environmental**: device unreachable, port busy, CP2102 driver wedged. Suggest the specific recovery in escalation order: (a) replug USB, (b) `touch_1200bps(port=...)` + `pio_flash` for nRF52 DFU, (c) `uhubctl_cycle(role="nrf52", confirm=True)` when a device is fully wedged past DFU (needs `uhubctl` installed — `baked_single`'s auto-recovery hook does this once automatically). Also check `git status userPrefs.jsonc`.
+   - **Regression**: same assertion fails repeatedly, firmware log shows a new/unusual error. Surface the diff between expected and observed, identify the module likely responsible.
+
+6. **Never run destructive recovery automatically.** If a failure looks like it needs a reflash, factory*reset, `uhubctl_cycle`, or USB replug, \_describe what to do* — don't execute. The operator decides.
+
+## Arguments handling
+
+- No args → wrapper's defaults (full suite).
+- `$ARGUMENTS` passed verbatim to the wrapper, which passes them to pytest.
+- Common operator invocations: `/test tests/mesh`, `/test tests/mesh/test_direct_with_ack.py::test_direct_with_ack_roundtrip`, `/test --force-bake`, `/test -k telemetry`.
+
+## Side-effects to mention in summary
+
+- The session fixture snapshots `userPrefs.jsonc` at session start and restores at teardown (plus on `atexit`). After a clean run, `git status userPrefs.jsonc` should be empty. If the wrapper's pre-flight printed a warning about a stale sidecar, call that out — means a prior session crashed.
+- `mcp-server/tests/report.html` and `junit.xml` are regenerated on every run; the HTML is self-contained (shareable).

+# Meshtastic Firmware - Copilot Instructions
+
+This document provides context and guidelines for AI assistants working with the Meshtastic firmware codebase.
+
+## Project Overview
+
+Meshtastic is an open-source LoRa mesh networking project for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware enables text messaging, location sharing, and telemetry over a decentralized mesh network. The project uses **C++17** as its language standard across all platforms.
+
+### Supported Hardware Platforms
+
+- **ESP32** (ESP32, ESP32-S3, ESP32-C3, ESP32-C6) - Most common platform
+- **nRF52** (nRF52840, nRF52833) - Low power Nordic chips
+- **RP2040/RP2350** - Raspberry Pi Pico variants
+- **STM32WL** - STM32 with integrated LoRa
+- **Linux/Portduino** - Native Linux builds (Raspberry Pi, etc.)
+- **macOS native** - Headless `meshtasticd` on Apple Silicon / x86_64; see `variants/native/portduino/platformio.ini` for Homebrew prereqs + CH341 LoRa setup
+
+### Supported Radio Chips
+
+- **SX1262/SX1268** - Sub-GHz LoRa (868/915 MHz regions)
+- **SX1280** - 2.4 GHz LoRa
+- **LR1110/LR1120/LR1121** - Wideband radios (sub-GHz and 2.4 GHz capable, but not simultaneously)
+- **RF95** - Legacy RFM95 modules
+- **LLCC68** - Low-cost LoRa
+
+### MQTT Integration
+
+MQTT provides a bridge between Meshtastic mesh networks and the internet, enabling nodes with network connectivity to share messages with remote meshes or external services.
+
+#### Key Components
+
+- **`src/mqtt/MQTT.cpp`** - Main MQTT client singleton, handles connection and message routing
+- **`src/mqtt/ServiceEnvelope.cpp`** - Protobuf wrapper for mesh packets sent over MQTT
+- **`moduleConfig.mqtt`** - MQTT module configuration
+
+#### MQTT Topic Structure
+
+Messages are published/subscribed using a hierarchical topic format:
+
+```
+{root}/{channel_id}/{gateway_id}
+```
+
+- `root` - Configurable prefix (default: `msh`)
+- `channel_id` - Channel name/identifier
+- `gateway_id` - Node ID of the publishing gateway
+
+#### Configuration Defaults (from `Default.h`)
+
+```cpp
+#define default_mqtt_address "mqtt.meshtastic.org"
+#define default_mqtt_username "meshdev"
+#define default_mqtt_password "large4cats"
+#define default_mqtt_root "msh"
+#define default_mqtt_encryption_enabled true
+#define default_mqtt_tls_enabled false
+```
+
+#### Key Concepts
+
+- **Uplink** - Mesh packets sent TO the MQTT broker (controlled by `uplink_enabled` per channel)
+- **Downlink** - MQTT messages received and injected INTO the mesh (controlled by `downlink_enabled` per channel)
+- **Encryption** - When `encryption_enabled` is true, only encrypted packets are sent; plaintext JSON is disabled
+- **ServiceEnvelope** - Protobuf wrapper containing packet + channel_id + gateway_id for routing
+- **JSON Support** - Optional JSON encoding for integration with external systems (disabled on nRF52 by default)
+
+#### PKI Messages
+
+PKI (Public Key Infrastructure) messages have special handling:
+
+- Accepted on a special "PKI" channel
+- Allow encrypted DMs between nodes that discovered each other on downlink-enabled channels
+
+## Encryption & Key Management
+
+Meshtastic packets on the air are typically encrypted one of two ways: the **per-channel symmetric** layer (AES-CTR with a shared PSK) for broadcasts and channel traffic, and the **per-peer PKI** layer (X25519 ECDH → AES-256-CCM) for direct messages and remote admin. A channel with a 0-byte PSK (or Ham mode, which wipes PSKs) transmits cleartext — see the size table below. Both are implemented in `src/mesh/CryptoEngine.cpp`; the send/receive dispatch lives in `src/mesh/Router.cpp`; admin authorization lives in `src/modules/AdminModule.cpp`.
+
+### High-level model
+
+- **Channels** are symmetric rooms: anyone with the PSK can read any message on the channel. Channel 0 is the "primary" channel and ships with the short-form default PSK on factory devices, forming the public mesh most users join. (The LoRa modem preset `LONG_FAST` lives on `config.lora.modem_preset` and is an independent field — don't conflate "channel 0 default PSK" with the modem preset name.)
+- **DMs** addressed to a single node require PKI so that other holders of the channel PSK can't read them. Outside Ham mode, Meshtastic does not fall back to channel-symmetric encryption when the destination public key is unknown.
+- **Remote admin** is a DM carrying an `AdminMessage`. The receiver only acts on it if the sender's public key is on its allowlist (`config.security.admin_key[0..2]`).
+- **Ham mode** (`owner.is_licensed=true`, where `owner` is the local `meshtastic_User` record) disables PKI entirely and sends cleartext — FCC Part 97 prohibits encryption on amateur bands.
+- **No ratchet, no session.** Every packet is encrypted from scratch — a stateless design that matches the high-loss, store-and-forward nature of LoRa.
+
+### Symmetric channel encryption (AES-CTR)
+
+`CryptoEngine::encryptPacket` / `decrypt` / `encryptAESCtr` in `src/mesh/CryptoEngine.cpp`.
+
+- **Cipher**: AES-CTR, AES-128 or AES-256 depending on key length. Same routine in both directions (CTR is a stream cipher, so encrypt == decrypt).
+- **Key**: `ChannelSettings.psk` bytes. Size semantics:
+  - **0 bytes** → no encryption, cleartext on the air
+  - **1 byte** → short-form index into the well-known `defaultpsk[]` in `src/mesh/Channels.h`. Index 0 = cleartext; 1 = defaultpsk unchanged; 2..255 = defaultpsk with its last byte incremented by (index − 1). This is what the CLI's `--ch-set psk default` produces.
+  - **16 bytes** → raw AES-128 key
+  - **32 bytes** → raw AES-256 key
+  - **2..15 bytes** → zero-padded to 16 and used as AES-128 (with a warn log); **17..31 bytes** → zero-padded to 32 and used as AES-256 (with a warn log). Defensive fallback for malformed PSK input, not something to rely on.
+- **Nonce (128 bit)**: `packet_id` (u64 LE) ‖ `from_node` (u32 LE) ‖ `block_counter` (u32, starts at 0). Built in `CryptoEngine::initNonce`.
+- **No AEAD**: channel packets carry no MAC, so the channel-hash byte is not an integrity or authenticity check. `Channels::getHash` is a 1-byte XOR-derived hint over the channel name bytes and PSK bytes that helps receivers pick a candidate channel/PSK for decryption. Because it is only a small hint and collisions are easy to find, it should be described purely as a PSK-selection aid, not as a security filter an attacker cannot bypass.
+- **Channel 0 is special in one way only**: it's the channel the Router attempts PKI decryption on before falling through to AES-CTR. Non-zero channels always go straight to AES-CTR.
+
+### PKI encryption for DMs (X25519 ECDH + AES-256-CCM)
+
+`CryptoEngine::encryptCurve25519` / `decryptCurve25519` in `src/mesh/CryptoEngine.cpp`.
+
+- **Keypair**: Curve25519 (aka X25519), 32-byte public + 32-byte private. Stored in `config.security.public_key` / `private_key`; the public half is mirrored into `owner.public_key` so it rides along in NodeInfo broadcasts and propagates through the mesh like any other identity field.
+- **Key generation** (`generateKeyPair`): stirs `HardwareRNG::fill()` (64 B from platform TRNG when available), the 16-byte `myNodeInfo.device_id`, and a call to `random()` into the rweather/Crypto library's software RNG, then `Curve25519::dh1`. `regeneratePublicKey` recomputes the public half from a known private (used when restoring from backup).
+- **Keygen entry points**: at boot, `NodeDB` calls `generateKeyPair` (or `regeneratePublicKey` when a stored private key is present and passes a low-entropy check) **directly** when `!owner.is_licensed` and `config.lora.region != UNSET`. `ensurePkiKeys` wraps the same logic for runtime/admin flows — it's the path `AdminModule::handleSetConfig` runs when first assigning a valid region or when security config is written; **do not assume it's the universal boot-time gate**, because the NodeDB path bypasses it.
+- **Handshake**: `Curve25519::dh2(local_private, remote_public) → 32-byte shared secret → SHA-256 → 32-byte AES-256 key`. Recomputed per packet. The SHA-256 step is effectively a KDF over the raw ECDH output.
+- **Cipher**: AES-256-CCM via `aes_ccm_ae` / `aes_ccm_ad` (`src/mesh/aes-ccm.cpp`). MAC length (the `M` parameter) is **8 bytes**. No AAD — the MAC covers ciphertext only.
+- **Nonce (13 bytes / 104 bit)**: `aes_ccm_ae`/`aes_ccm_ad` use a 13-byte CCM nonce (`L = 2` is hardcoded in `src/mesh/aes-ccm.cpp`), not a 16-byte nonce. For PKI packets, `CryptoEngine::initNonce(fromNode, packetNum, extraNonce)` starts from the usual packet-derived nonce material, then overwrites nonce bytes `4..7` with a fresh 32-bit `extraNonce = random()`. The effective nonce bytes are therefore: bytes `0..3` = `packet_id`, bytes `4..7` = transmitted `extraNonce`, bytes `8..11` = `from_node`, byte `12` = `0x00`. The receiver reconstructs the same 13-byte nonce from the packet metadata plus the appended `extraNonce`.
+- **Wire overhead**: 12 bytes appended to the ciphertext = 8-byte MAC ‖ 4-byte extraNonce. Defined as `MESHTASTIC_PKC_OVERHEAD = 12` in `src/mesh/RadioInterface.h`. Only the 4-byte `extraNonce` is sent; the rest of the 13-byte CCM nonce is reconstructed from packet fields as described above. The Router's send path checks this overhead against `MAX_LORA_PAYLOAD_LEN` before committing to PKI.
+- **Send selection** (`Router::send`): the sender enters the PKI path when **all** hold — we're the originator AND not Ham mode AND not Portduino simradio AND not on the `serial`/`gpio` channels (unless the packet is already marked `pki_encrypted`) AND `config.security.private_key.size == 32` AND destination is a single node (not broadcast) AND the portnum isn't infrastructure. `TRACEROUTE_APP`, `NODEINFO_APP`, `ROUTING_APP`, and `POSITION_APP` are routed through channel encryption even when DMed (these need to be readable by relaying peers). Once on the PKI path, if the destination's public key isn't in our NodeDB the send **fails** with `PKI_SEND_FAIL_PUBLIC_KEY` — it does not silently fall back to channel encryption. If the client explicitly set `pki_encrypted=true` and any condition blocks PKI, the send fails with `PKI_FAILED`.
+- **Receive selection** (`Router::perhapsDecode`): try PKI decrypt first when `channel == 0` AND `isToUs(p)` AND not broadcast AND both peers have public keys in NodeDB AND `rawSize > MESHTASTIC_PKC_OVERHEAD`. On success the packet gets `pki_encrypted=true` stamped and the sender's public key copied into `p->public_key` for downstream authorization.
+
+### Remote admin authorization
+
+Implemented in `src/modules/AdminModule.cpp` → `handleReceivedProtobuf`. The authorization check runs in this order:
+
+1. **Response messages** — if `messageIsResponse(r)` is true (the payload is a response to one of our earlier admin requests), it's accepted without any further check. The in-file comment flags this as a known-untightened gap: a stricter implementation would remember which `public_key` we last queried and reject responses that don't match.
+2. **Local admin** — `mp.from == 0` (phone app over BLE, serial CLI, internal module); never travels over the air. **Rejected** if `config.security.is_managed` is true, because managed devices expect admin to arrive over the air through an authorized remote path.
+3. **Legacy admin channel (deprecated)** — the packet arrived on a channel named literally `"admin"`. Gated by `config.security.admin_channel_enabled`; returns `NOT_AUTHORIZED` if the flag is false. Kept for backward compatibility; new deployments should use PKI admin.
+4. **PKI admin (preferred for remote)** — `mp.pki_encrypted == true` AND `mp.public_key` matches one of `config.security.admin_key[0..2]` (up to three authorized 32-byte Curve25519 public keys, typically copied from the admin node's own `user.public_key`).
+5. **Fallthrough** → `NOT_AUTHORIZED`.
+
+On top of authorization, any remote admin message that **mutates** state (not a request, not a response) also has to pass a session-key check (`checkPassKey`): the client must first pull a fresh 8-byte `session_passkey` via `get_admin_session_key_request`, then echo that passkey back in the mutating message. The device rotates the passkey after 150 s and rejects values older than 300 s — a narrow anti-replay window on top of the PKI layer.
+
+`config.security.is_managed = true` disables **local** admin writes (`mp.from == 0` is rejected). It does not by itself force every admin action through PKI — the legacy `"admin"` channel still authorizes remote admin when `config.security.admin_channel_enabled == true`. The AdminModule refuses to persist `is_managed=true` unless at least one `admin_key` is populated — a deliberate guard against operators locking themselves out.
+
+### Key-rotation hazards (actions that invalidate peers)
+
+- **`factory_reset_device`** (the "full" variant, calls `NodeDB::factoryReset(eraseBleBonds=true)`) → **wipes** the X25519 private key; a fresh keypair is generated on the next region-set. Every existing peer holds the old public key, so DMs to this node silently fail PKI decrypt until every peer re-exchanges NodeInfo.
+- **`factory_reset_config`** (the "partial" variant, calls `NodeDB::factoryReset()` with `eraseBleBonds=false`) → **preserves** the X25519 private key in `installDefaultConfig(preserveKey=true)`; the public key is zeroed and gets rebuilt from the preserved private key on the next boot via the NodeDB path's `regeneratePublicKey` call. Identity is preserved and the mesh does not need to re-exchange keys.
+- **`region=UNSET → valid region`** → `ensurePkiKeys` runs inside the same `handleSetConfig` path; missing keys get generated at that moment.
+- **Ham mode transitions** — entering Ham mode (`user.is_licensed=true`) runs `Channels::ensureLicensedOperation`, which **wipes every channel PSK** (all traffic becomes cleartext) and disables the legacy admin channel. The X25519 private key is preserved on the device but not used because `Router::send` skips PKI when `owner.is_licensed` is true. Leaving Ham mode re-enables PKI with the preserved keypair but does not restore the wiped channel PSKs — the operator has to re-set them.
+- **Channel 0 PSK change** → every peer must re-learn the channel hash; cached NodeInfo becomes temporarily unreachable until the next broadcast.
+- **`security.private_key` blanked via admin** → regenerates both halves (unless in Ham mode) and propagates the new public key via NodeInfo.
+

+`DEVICESTATE_CUR_VER = 25`, `DEVICESTATE_MIN_VER = 24`. The on-device NodeDB was split in v25 into a slim header table plus four optional satellite stores. Older v24 saves auto-migrate at boot. Old training-data instincts (`node->user.long_name`, `node->position.latitude_i`, `node->is_favorite`, `node->device_metrics.battery_level`) are wrong now — the fields aren't there. Read this section before touching anything that walks `nodeDB->meshNodes`.
+
+### Slim `NodeInfoLite`
+
+`UserLite` is flattened onto `NodeInfoLite` (no nested sub-message); `position` and `device_metrics` are removed entirely (tags reserved). MAC address is dropped. Long names are capped at 25 chars (`max_size:25` in `deviceonly.options`); `hw_model` and `role` are `int_size:8`. Encoded size dropped from ~166 B → ~105 B per node.
+
+Booleans are bit-packed into `NodeInfoLite.bitfield`. **Do not read or write the bits directly** — use the inline helpers in `src/mesh/NodeDB.h`:
+
+```cpp
+nodeInfoLiteHasUser(n)                  // bit 5 — user fields populated
+nodeInfoLiteIsFavorite(n)               // bit 3
+nodeInfoLiteIsIgnored(n)                // bit 4
+nodeInfoLiteIsMuted(n)                  // bit 1
+nodeInfoLiteIsLicensed(n)               // bit 6 — Ham mode peer
+nodeInfoLiteIsKeyManuallyVerified(n)    // bit 0
+nodeInfoLiteHasIsUnmessagable(n)        // bit 8 — "is_unmessagable was sent"
+nodeInfoLiteIsUnmessagable(n)           // bit 7
+// via_mqtt is bit 2 (mask exposed; predicate uses the mask directly)
+
+nodeInfoLiteSetBit(n, NODEINFO_BITFIELD_IS_FAVORITE_MASK, true);  // setter
+```
+
+### Satellite stores
+
+Four `std::unordered_map<NodeNum, …>` members on `NodeDB`, each gated by its own build flag:
+
+| Map               | Value type                      | Build flag                         |
+| ----------------- | ------------------------------- | ---------------------------------- |
+| `nodePositions`   | `meshtastic_PositionLite`       | `MESHTASTIC_EXCLUDE_POSITIONDB`    |
+| `nodeTelemetry`   | `meshtastic_DeviceMetrics`      | `MESHTASTIC_EXCLUDE_TELEMETRYDB`   |
+| `nodeEnvironment` | `meshtastic_EnvironmentMetrics` | `MESHTASTIC_EXCLUDE_ENVIRONMENTDB` |
+| `nodeStatus`      | `meshtastic_StatusMessage`      | `MESHTASTIC_EXCLUDE_STATUSDB`      |
+
+Defaults are ON (i.e., maps **excluded**) for STM32WL only — see `src/mesh/mesh-pb-constants.h`. On every other arch all four maps are present. When excluded, the map member is absent and the corresponding accessors return `false`.
+
+All four maps are guarded by **`mutable concurrency::Lock satelliteMutex`** — concurrent access from receive threads, the phone API state machine, and the renderer is the rule, not the exception.
+
+### Accessor convention
+
+**Never hand out pointers into the maps.** Use the copy-out accessors on `NodeDB`:
+
+```cpp
+bool copyNodePosition(NodeNum, meshtastic_PositionLite &out)       const;
+bool copyNodeTelemetry(NodeNum, meshtastic_DeviceMetrics &out)     const;
+bool copyNodeEnvironment(NodeNum, meshtastic_EnvironmentMetrics &out) const;
+bool copyNodeStatus(NodeNum, meshtastic_StatusMessage &out)        const;
+```
+
+Each takes the lock, copies the value if present, returns `false` if the entry is absent or the DB is excluded. Pass-by-out-param is deliberate — pointer-style accessors would invite UAF and lock-leak bugs across the renderer. The "has any X" convenience predicates (`hasValidPosition` etc.) are implemented in terms of these.
+
+Writers go through `setNodeStatus`, `updatePosition`, `updateTelemetry` (which dispatches on `which_variant` for device vs environment metrics) — these own the lock and the eviction hooks.
+
+### Eviction
+
+Every code path that drops a node from the header table must also evict the satellites. The single chokepoint is `eraseNodeSatellites(NodeNum)`; it's already called from `getOrCreateMeshNode`'s oldest-boring eviction, `demoteOldestHotNodesToWarm` (the over-cap warm-tier migration), `removeNodeByNum`, both branches of `resetNodes`, `cleanupMeshDB`, `addFromContact`'s ignored-branch, and `AdminModule`'s `set_ignored_node`. Add new eviction sites here, not by calling `.erase()` directly. (Note: `enforceSatelliteCaps`/`evictSatelliteOverCap` call `.erase()` directly on purpose — that's a satellite-only cap trim where the node _stays_ in the header, a different operation from this chokepoint.)
+
+### Warm tier (long-tail identity)
+
+On every arch except STM32WL and bare nRF52832 (`WARM_NODE_COUNT > 0`), a node evicted from the header table is not forgotten outright: `WarmNodeStore` (`src/mesh/WarmNodeStore.{h,cpp}`) keeps a 40 B `{num, last_heard, public_key}` record per evicted node — primarily so PKI DMs to/from a long-tail node keep decrypting without re-running a NodeInfo exchange (the rest of `NodeInfoLite` rebuilds from traffic in seconds).
+
+- **Write:** `getOrCreateMeshNode`'s eviction and `demoteOldestHotNodesToWarm` (the over-cap boot migration) call `warmStore.absorb(num, last_heard, key)` _before_ the node leaves the header.
+- **Read-back:** `getOrCreateMeshNode` calls `warmStore.take()` to rehydrate `last_heard` + key when a warm node is re-admitted; `copyPublicKey()` falls back to the warm tier so the PKI send path finds keys for evicted peers.
+- **Persistence:** nRF52840 uses a 12 KB raw-flash record-ring at `0xEA000` (below LittleFS; append + replay + compact-on-rotate, link-guarded by `nrf52840_s140_v7.ld` and `extra_scripts/nrf52_warm_region.py`). Everywhere else: a `/prefs/warm.dat` snapshot flushed by `saveIfDirty()` on the node-DB save cadence.
+- **Tunables** (`mesh-pb-constants.h`): `WARM_NODE_COUNT` (per-arch; `0` disables the tier) and `MAX_NUM_NODES` (hot cap — 120 on nRF52840/generic ESP32 to fit the 28 KB LittleFS; ESP32-S3 keeps its flash-scaled 100/200/250, portduino 250). Verbose migration/self-care tracing routes through `LOG_MIGRATION`, gated by `MESHTASTIC_NODEDB_MIGRATION_VERBOSE`.
+
+### Satellite caps
+
+Only the freshest `MAX_SATELLITE_NODES` nodes keep satellite payloads; the rest of the header table carries just the `NodeInfoLite`. The cap is **per-platform**: 40 on RAM-constrained parts (nRF52840, generic ESP32) since the four maps live in internal SRAM (not PSRAM, ~408 B/node across the four), and 250 on flash-rich hosts (ESP32-S3, portduino) so every hot node can carry rich data as before the cap existed. `enforceSatelliteCaps()` trims each map to the cap on load (returns whether it trimmed); `evictSatelliteOverCap()` trims before each insert. Eviction is by the owning node's hot `last_heard` (stalest first, demoted/absent nodes rank as `last_heard==0`); self is never trimmed.
+
+### On-boot self-care
+
+`NodeDB::nodeDBSelfCare()` runs once identity is established (the constructor after key (re)gen, and `reloadFromDisk()` — _not_ inside `loadFromDisk`, where `getNodeNum()` is still 0). It confirms self is present (warns if a non-empty DB is missing us — a foreign/over-cap file), pins self to index 0, demotes/trims only **non-self** overflow into the warm tier, then rewrites `nodes.proto` **once** and only if it healed something — and never while encrypted storage is locked (it would persist placeholder defaults). `loadFromDisk` deliberately leaves the loaded store untrimmed for this pass.
+
+### Sync flow: thin NodeInfo + post-COMPLETE_ID replay (no opt-in)
+
+There is no capability flag and no special "gradient" nonce. The **default** sync flow is:
+
+1. Config / module-config / channel / metadata segments (same as before).
+2. `STATE_SEND_OWN_NODEINFO` — **our own** NodeInfo, still bundled with our position and device_metrics (because the replay snapshot excludes our own NodeNum). Emitted via `ConvertToNodeInfo(lite)`.
+3. `STATE_SEND_OTHER_NODEINFOS` — every other peer's NodeInfo, **always thin** (no `position`, no `device_metrics`). Emitted via `ConvertToNodeInfoThin(lite)`.
+4. `STATE_SEND_FILEMANIFEST` → `STATE_SEND_COMPLETE_ID` — the phone sees `config_complete_id` and treats sync as done.
+5. `STATE_SEND_PACKETS` — live mesh packets, with a trailing replay drain interleaved. The replay drain walks four cached satellite stores in order (positions → telemetry → environment → status) and emits each cached entry as an ordinary `MeshPacket` on the matching portnum (`POSITION_APP`, `TELEMETRY_APP` device + environment variants, `NODE_STATUS_APP`). These are indistinguishable on the wire from live mesh traffic, so clients need no special handling — any code that already updates UI on `POSITION_APP` etc. works.
+
+`PhoneAPI::sendConfigComplete()` arms `replayPhase = REPLAY_PHASE_POSITIONS` for default/full sync and `SPECIAL_NONCE_ONLY_NODES`, while `SPECIAL_NONCE_ONLY_CONFIG` skips replay. The drain runs inside `STATE_SEND_PACKETS` via `popReplayPacket()`, lower priority than live traffic. When all four phases drain, `replayPhase` flips back to `REPLAY_PHASE_IDLE` and the snapshot vectors get `shrink_to_fit`ed.
+
+STM32WL and any other build with all four `MESHTASTIC_EXCLUDE_*DB` flags set produces zero replay packets — `popReplayPacket` advances through each phase in microseconds without emitting anything.
+
+Special nonces that still mean something:
+
+- `SPECIAL_NONCE_ONLY_CONFIG` (69420) — skip node sync entirely, just config.
+- `SPECIAL_NONCE_ONLY_NODES` (69421) — skip config segments, jump straight to `STATE_SEND_OWN_NODEINFO`. Still gets the post-COMPLETE_ID replay drain.
+
+There are no other reserved nonces; everything else is a fresh random `want_config_id` from the client.
+
+### v24 → v25 migration
+
+The legacy migration code lives in **`src/mesh/NodeDBLegacyMigration.cpp`**, not in `NodeDB.cpp`. It owns the `meshtastic_NodeDatabase_Legacy` callback and `NodeDB::migrateLegacyNodeDatabase()`. The legacy proto descriptor is `protobufs/meshtastic/deviceonly_legacy.proto` (only included by the migration TU). The boot path peeks the file's leading version tag, runs the migration if `version < 25`, then re-saves in v25 layout. The legacy descriptor is scheduled for removal once `DEVICESTATE_MIN_VER` is bumped.
+
+### Read-site rules of thumb
+
+- Never `node->position.X` / `node->device_metrics.X` — those fields no longer exist. Pull from the satellite map via `copyNodePosition` / `copyNodeTelemetry`.
+- Never `node->user.long_name` — `long_name`, `short_name`, `public_key`, `hw_model`, `role`, `macaddr` (gone), `is_licensed`, `is_unmessagable` are flat on `NodeInfoLite`.
+- Never `node->is_favorite` / `node->is_ignored` / `node->via_mqtt` / `node->is_key_manually_verified` — use the bitfield helpers.
+- Never assume `nodeDB->getMeshNode(num)->position.time` — call `copyNodePosition` and check the return.
+- Don't lock `satelliteMutex` yourself in renderer code; the copy-out accessors already do.
+
+Unit tests for the conversion layer live in `test/test_type_conversions/test_main.cpp` (Unity) — bitfield round-trips, `long_name` truncation, thin-vs-full conversions. Add cases there when extending the schema.

+
+## Coding Conventions
+
+### Formatting & the trunk toolchain
+
+`trunk fmt` is the project formatter (`trunk_check` CI rejects unformatted code). For Claude Code users, `.claude/settings.json` ships a PostToolUse hook that runs `trunk fmt --force` on every file the agent writes or edits. The hook is pure sh/grep/sed — no python or jq required — but trunk itself must be able to run:
+
+- Trunk's launcher (`~/.cache/trunk/launcher/trunk`, or `trunk` on PATH) downloads the CLI version pinned in `.trunk/trunk.yaml` on first use and again whenever that pin is bumped. **The launcher needs `curl` or `wget`**; without one it fails with "Cannot download… please install curl or wget", and the hook surfaces that as a warning on every write.
+- No curl/wget available (e.g. a minimal WSL image)? Bootstrap by hand with any Python (PlatformIO bundles one at `~/.platformio/penv/bin/python`): download `https://trunk.io/releases/<ver>/trunk-<ver>-linux-x86_64.tar.gz` and place the `trunk` binary at `~/.cache/trunk/cli/<ver>-linux-x86_64/trunk` (chmod +x), where `<ver>` is the `cli.version` from `.trunk/trunk.yaml`.
+- The hook fails loudly by design (visible warning, non-blocking). Silent no-op formatting hooks hide real breakage — don't re-add `2>/dev/null || true` around the whole thing.
+- More generally: don't assume a stock Linux userland in hooks or helper scripts — minimal WSL/container images may lack `python3`, `curl`, `wget`, and `jq`. Prefer plain sh + coreutils, or PlatformIO's bundled Python for anything heavier.
+
+### General Style
+
+- Follow existing code style - run `trunk fmt` before commits
+- Prefer `LOG_DEBUG`, `LOG_INFO`, `LOG_WARN`, `LOG_ERROR` for logging
+- Use `assert()` for invariants that should never fail
+- C++17 features are available (`std::optional`, structured bindings, `if constexpr`, etc.)
+- **Keep code comments minimal — one or two lines, max.** Comment only when the _why_ isn't obvious from the code; never restate what the next line does. No multi-paragraph block comments explaining straightforward changes. The diff and commit message carry the rationale; the code carries the behavior.
+- **Use `Throttle` for time-based rate limiting, not raw `millis()` math.** `src/mesh/Throttle.h` provides `Throttle::isWithinTimespanMs(lastMs, intervalMs)` (returns true while inside the cooldown) and `Throttle::execute(&lastMs, intervalMs, func)` (function-pointer form that updates the timestamp on fire). Use these for any "did N ms pass since X" check — raw `millis() > lastMs + N` is rollover-unsafe (breaks after ~49.7 days) and inconsistent with the rest of the codebase. The helpers compute `now - lastMs` with unsigned subtraction, which wraps correctly.
+
+### Naming Conventions
+
+- Classes: `PascalCase` (e.g., `PositionModule`, `NodeDB`)
+- Functions/Methods: `camelCase` (e.g., `sendOurPosition`, `getNodeNum`)
+- Constants/Defines: `UPPER_SNAKE_CASE` (e.g., `MAX_INTERVAL`, `ONE_DAY`)
+- Member variables: `camelCase` (e.g., `lastGpsSend`, `nodeDB`)
+- Config defines: `USERPREFS_*` for user-configurable options
+
+### Key Patterns
+
+#### Module System
+
+Modules use a three-tier class hierarchy:
+
+1. **`MeshModule`** - Base class. Implement `wantPacket()` and `handleReceived()`. Returns `ProcessMessage::STOP` or `ProcessMessage::CONTINUE`.
+2. **`SinglePortModule`** - Handles a single portnum. Simplified `wantPacket()` that checks `decoded.portnum`.
+3. **`ProtobufModule<T>`** - Template for protobuf-based modules. Handles encoding/decoding automatically.
+
+Most modules also inherit from **`OSThread`** for periodic tasks (the "mixin" pattern):
+
+```cpp
+class MyModule : public ProtobufModule<meshtastic_MyMessage>, private concurrency::OSThread
+{
+  public:
+    MyModule();
+
+  protected:
+    virtual bool handleReceivedProtobuf(const meshtastic_MeshPacket &mp, meshtastic_MyMessage *msg) override;
+    virtual meshtastic_MeshPacket *allocReply() override;       // Generate response packets
+    virtual int32_t runOnce() override;                         // Periodic task (returns next interval in ms)
+    virtual bool alterReceivedProtobuf(meshtastic_MeshPacket &mp, meshtastic_MyMessage *msg); // Modify in-flight
+    virtual bool wantUIFrame();                                 // Request a UI display frame
+};
+```
+
+Modules are registered in `src/modules/Modules.cpp` guarded by `MESHTASTIC_EXCLUDE_*` flags.
+
+#### Observer/Observable Pattern
+
+Event-driven communication between subsystems uses `src/Observer.h`:
+
+```cpp
+// Observable emits events
+Observable<const meshtastic::Status *> newStatus;
+newStatus.notifyObservers(&status);
+
+// Observer receives events via callback
+CallbackObserver<MyClass, const meshtastic::Status *> statusObserver =
+    CallbackObserver<MyClass, const meshtastic::Status *>(this, &MyClass::handleStatusUpdate);
+```
+
+#### Configuration Access
+
+- `config.*` - Device configuration (LoRa, position, power, etc.)
+- `moduleConfig.*` - Module-specific configuration
+- `channels.*` - Channel configuration and management
+- `owner` - Device owner info
+- `myNodeInfo` - Local node info
+
+#### Default Values
+
+Use the `Default` class helpers in `src/mesh/Default.h`:
+
+- `Default::getConfiguredOrDefaultMs(configured, default)` - Returns ms, using default if configured is 0
+- `Default::getConfiguredOrDefault(configured, default)` - Generic configured/default getter
+- `Default::getConfiguredOrMinimumValue(configured, min)` - Enforces minimum values
+- `Default::getConfiguredOrDefaultMsScaled(configured, default, numNodes)` - Scales based on network size
+
+#### Thread Safety
+
+- Use `concurrency::Lock` and `concurrency::LockGuard` for mutex protection
+- Radio SPI access uses `SPILock`
+- Prefer `OSThread` for background tasks
+
+### Hardware Detection
+
+`src/detect/ScanI2C` automatically enumerates 80+ I2C device types at boot including displays, sensors, RTCs, keyboards, PMUs, and touch controllers. This drives automatic initialization of the correct drivers.
+
+### Graphics/UI System
+
+Multiple display driver families in `src/graphics/`:
+
+- **OLED**: SSD1306, SH1106, ST7567
+- **TFT**: TFTDisplay (LovyanGFX-based)
+- **E-Ink**: EInkDisplay2, EInkDynamicDisplay, EInkParallelDisplay
+
+**InkHUD** (`src/graphics/niche/InkHUD/`) is an event-driven e-ink UI framework:
+
+- Applet-based architecture — modular display tiles
+- Read-only, static display optimized for minimal refreshes and low power
+- Configured per-variant via `nicheGraphics.h`
+- Separate PlatformIO config: `src/graphics/niche/InkHUD/PlatformioConfig.ini`
+
+### Input System
+
+`src/input/InputBroker` is the centralized input event dispatcher. Supports multiple input sources: buttons, keyboards (BBQ10, Cardputer, TCA8418), touch screens, rotary encoders, and matrix keyboards.
+
+### Power Management
+
+`src/PowerFSM.*` implements a finite state machine with states: `stateON`, `statePOWER`, `stateSERIAL`, `stateDARK`. Key events: `EVENT_PRESS`, `EVENT_WAKE_TIMER`, `EVENT_LOW_BATTERY`, `EVENT_RECEIVED_MSG`, `EVENT_SHUTDOWN`. Conditionally excluded with `MESHTASTIC_EXCLUDE_POWER_FSM` (falls back to `FakeFsm`).
+
+### Motion Sensors
+
+`src/motion/AccelerometerThread` provides background motion monitoring with automatic screen wake and double-tap button press detection. Supports 10+ accelerometer/gyroscope chips (BMA423, BMI270, MPU6050, LIS3DH, LSM6DS3, STK8XXX, QMA6100P, ICM20948, BMX160).
+
+### Telemetry Sensor Library
+
+`src/modules/Telemetry/Sensor/` contains 50+ I2C sensor drivers organized by category:
+
+- **Power monitoring**: INA219/226/260/3221, MAX17048
+- **Environmental**: BME280/680, SCD4X (CO₂), SEN5X (particulate)
+- **Humidity/Temperature**: SHT3X/4X, AHT10, MCP9808, MLX90614
+- **Light**: BH1750, TSL2561/2591, VEML7700, LTR390UV, OPT3001
+- **Air quality**: PMSA003I, SFA30
+- **Specialized**: CGRadSens (radiation), NAU7802 (weight scale)
+
+### API/Networking
+
+`src/mesh/api/` provides a template-based `ServerAPI` for client communication over WiFi (`WiFiServerAPI`) and Ethernet (`ethServerAPI`). Default port: **4403**. HTTP server in `src/mesh/http/`. JSON serialization in `src/serialization/MeshPacketSerializer`.
+
+### Hardware Variants
+
+Each hardware variant has:
+
+- `variant.h` - Pin definitions and hardware capabilities
+- `platformio.ini` - Build configuration
+- Optional: `pins_arduino.h`, `rfswitch.h`, `nicheGraphics.h` (for InkHUD variants)
+
+Key defines in variant.h:
+
+```cpp
+#define USE_SX1262          // Radio chip selection
+#define HAS_GPS 1           // Hardware capabilities
+#define HAS_SCREEN 1        // Display present
+#define LORA_CS 36          // Pin assignments
+#define SX126X_DIO1 14      // Radio-specific pins
+```
+
+### Protobuf Messages
+
+- Defined in `protobufs/meshtastic/*.proto` (~32 proto files)
+- Generated code in `src/mesh/generated/meshtastic/`
+- Regenerate with `bin/regen-protos.sh`
+- Message types prefixed with `meshtastic_`
+- Nanopb `.options` files control field sizes and encoding
+

+- **Required CLI basics**: `bash`, `git`, `find`, `grep`, `sed`, `awk`, `xargs`
+- **Strongly recommended**: `rg` (ripgrep) for fast file/text search, `jq` for JSON processing
+- **Build/test tools**: `python3`, `pip`, virtualenv (`python3 -m venv`), `platformio` (`pio`)
+- **Containerized native testing**: `docker` (fallback for non-Linux hosts; macOS can also build natively via `pio run -e native-macos`)
+
+Fallback expectations for agents:
+
+- If `rg` is unavailable, use `find` + `grep` instead of failing.
+- For native tests on hosts without Linux deps, prefer `./bin/test-native-docker.sh`.
+- The simulator helper script is `./bin/test-simulator.sh`.
+
+Uses **PlatformIO** with custom scripts:
+
+- `bin/platformio-pre.py` - Pre-build script
+- `bin/platformio-custom.py` - Custom build logic, manifest generation
+
+Build commands:
+
+```bash
+pio run -e tbeam              # Build specific target
+pio run -e tbeam -t upload    # Build and upload
+pio run -e native             # Build native/Linux version
+pio run -e native-macos       # Build headless macOS meshtasticd (Homebrew prereqs in variants/native/portduino/platformio.ini)
+```
+
+### Build Manifest
+
+`bin/platformio-custom.py` emits a build manifest with metadata:
+
+- `hasMui`, `hasInkHud` - UI capability flags (overridable via `custom_meshtastic_has_mui`, `custom_meshtastic_has_ink_hud`)
+- Architecture normalization (e.g., `esp32s3` → `esp32-s3` for API compatibility)
+
+## Common Tasks
+
+### Adding a New Module
+
+1. Create `src/modules/MyModule.cpp` and `.h`
+2. Inherit from appropriate base class (`MeshModule`, `SinglePortModule`, or `ProtobufModule<T>`)
+3. Mix in `concurrency::OSThread` if periodic work is needed
+4. Register in `src/modules/Modules.cpp` guarded by `#if !MESHTASTIC_EXCLUDE_MYMODULE`
+5. Add protobuf messages if needed in `protobufs/meshtastic/`
+6. Add test suite in `test/test_mymodule/` if applicable
+
+### Adding a New Hardware Variant
+
+1. Create directory under `variants/<arch>/<name>/`
+2. Add `variant.h` with pin definitions and hardware capability defines
+3. Add `platformio.ini` with build config — use `extends` to reference common base (e.g., `esp32s3_base`)
+4. Set `custom_meshtastic_support_level = 1` (PR builds) or `2` (merge builds)
+5. For e-ink displays, add `nicheGraphics.h` for InkHUD configuration
+
+### Adding a New Telemetry Sensor
+
+1. Create driver in `src/modules/Telemetry/Sensor/` following existing sensor pattern
+2. Register I2C address in `src/detect/ScanI2C` for auto-detection
+3. Integrate with the appropriate telemetry module (Environment, Health, Power, AirQuality)
+4. Add proto fields in `protobufs/meshtastic/telemetry.proto` if new data types are needed
+
+### Modifying Configuration Defaults
+
+- Check `src/mesh/Default.h` for default value defines
+- Check `src/mesh/NodeDB.cpp` for initialization logic
+- Consider `isDefaultChannel()` checks for public channel restrictions
+
+## Important Considerations
+
+### Traffic Management
+
+The mesh network has limited bandwidth. When modifying broadcast intervals:
+
+- Respect minimum intervals on default/public channels
+- Use `Default::getConfiguredOrMinimumValue()` to enforce minimums
+- Consider `numOnlineNodes` scaling for congestion control
+
+### Power Management
+
+Many devices are battery-powered:
+
+- Use `IF_ROUTER(routerVal, normalVal)` for role-based defaults
+- Check `config.power.is_power_saving` for power-saving modes
+- Implement proper `sleep()` methods in radio interfaces
+
+### Channel Security
+
+- `channels.isDefaultChannel(index)` - Check if using default/public settings
+- Default channels get stricter rate limits to prevent abuse
+- Private channels may have relaxed limits
+
+## GitHub Actions CI/CD
+
+The project uses GitHub Actions extensively for CI/CD. Key workflows are in `.github/workflows/`:
+
+### Core CI Workflows
+
+- **`main_matrix.yml`** - Main CI pipeline, runs on push to `master`/`develop` and PRs
+  - Uses `bin/generate_ci_matrix.py` to dynamically generate build targets
+  - Builds all supported hardware variants
+  - PRs build a subset (`--level pr`) for faster feedback
+
+- **`trunk_check.yml`** - Code quality checks on PRs
+  - Runs Trunk.io for linting and formatting
+  - Must pass before merge
+
+- **`tests.yml`** - End-to-end and hardware tests
+  - Runs daily on schedule
+  - Includes native tests and hardware-in-the-loop testing
+
+- **`test_native.yml`** - Native platform unit tests
+  - Runs `pio test -e native`
+
+### Release Workflows
+
+- **`release_channels.yml`** - Triggered on GitHub release publish
+  - Builds Docker images
+  - Packages for PPA (Ubuntu), OBS (openSUSE), and COPR (Fedora)
+  - Handles Alpha/Beta/Stable release channels
+
+- **`nightly.yml`** - Nightly builds from develop branch
+
+- **`docker_build.yml`** / **`docker_manifest.yml`** - Docker image builds
+
+### Build Matrix Generation
+
+The CI uses `bin/generate_ci_matrix.py` to dynamically select which targets to build:
+
+```bash
+# Generate full build matrix
+./bin/generate_ci_matrix.py all
+
+# Generate PR-level matrix (subset for faster builds)
+./bin/generate_ci_matrix.py all --level pr
+```
+
+Variants can specify their support level in `platformio.ini`:
+
+- `custom_meshtastic_support_level = 1` - Actively supported, built on every PR
+- `custom_meshtastic_support_level = 2` - Supported, built on merge to main branches
+- `board_level = extra` - Extra builds, only on full releases
+
+### Running Workflows Locally
+
+Most workflows can be triggered manually via `workflow_dispatch` for testing.
+
+## Testing
+
+### Native unit tests (C++)
+
+Unit tests in `test/` directory with 17 test suites:
+
+- `test_admin_radio/` - LoRa region/config validation and AdminModule dispatch
+- `test_atak/` - ATAK integration
+- `test_crypto/` - Cryptography
+- `test_default/` - Default configuration
+- `test_http_content_handler/` - HTTP handling
+- `test_mac_from_string/` - MAC address parsing
+- `test_mesh_module/` - Module framework
+- `test_meshpacket_serializer/` - Packet serialization
+- `test_mqtt/` - MQTT integration
+- `test_packet_history/` - Packet history tracking
+- `test_position_precision/` - Position precision helpers
+- `test_radio/` - Radio interface
+- `test_serial/` - Serial communication
+- `test_traffic_management/` - Traffic management
+- `test_transmit_history/` - Retransmission tracking
+- `test_type_conversions/` - NodeDB v25 type conversion (bitfield round-trips, NodeInfoLite)
+- `test_utf8/` - UTF-8 utilities
+
+Run command (preferred — avoids pipe-buffering and the Ubuntu externally-managed-environment error):
+
+```bash
+~/.platformio/penv/bin/python -m platformio test -e native -f test_your_suite > /tmp/test_out.txt 2>&1
+grep -E 'error:|PASS|FAIL|succeeded|failed' /tmp/test_out.txt
+tail -15 /tmp/test_out.txt
+```
+
+Do **not** use `pio test … | tail -N` — it discards build errors and shows stale cached results. Do **not** use `pio test … | grep` — line-buffering makes the terminal appear hung until the process exits. Redirect to a file first, then grep.
+
+Simulation testing: `bin/test-simulator.sh`
+
+Quick entry point for new test modules: `test/README.md` (native unit-test authoring guide, skeleton, pitfalls, and setup checklist).
+
+### Hardware-in-the-loop tests (`mcp-server/tests/`)
+
+Separate pytest suite that exercises real USB-connected Meshtastic devices. See the **MCP Server & Hardware Test Harness** section below for invocation, tier layout, and agent usage rules.
+
+## MCP Server & Hardware Test Harness
+
+The `mcp-server/` directory houses a firmware-aware [MCP](https://modelcontextprotocol.io/) server plus a pytest-based integration suite. AI agents that speak MCP get a well-defined tool surface for flashing, configuring, and inspecting physical Meshtastic devices — use it instead of hand-rolling `pio` or `meshtastic --port` calls where possible. `mcp-server/README.md` is the operator-facing setup doc; this section is the agent-facing usage contract.
+
+The repo registers the server via `.mcp.json` at the repo root — Claude Code picks it up automatically once `mcp-server/.venv/` is built (`cd mcp-server && python3 -m venv .venv && .venv/bin/pip install -e '.[test]'`).
+
+### When to use which surface
+
+| Goal                                              | Tool                                                                                                             |
+| ------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- |
+| Find a connected device                           | `mcp__meshtastic__list_devices`                                                                                  |
+| Read a live node's config/state                   | `mcp__meshtastic__device_info`, `list_nodes`, `get_config`                                                       |
+| Mutate a device (owner, region, channels, reboot) | `set_owner`, `set_config`, `set_channel_url`, `reboot`, `shutdown`, `factory_reset` — all require `confirm=True` |
+| Flash firmware to a variant                       | `pio_flash` (any arch) or `erase_and_flash` (ESP32 factory install)                                              |
+| Stream serial logs while debugging                | `serial_open` → `serial_read` loop → `serial_close`                                                              |
+| Administer `userPrefs.jsonc` build-time constants | `userprefs_get`, `userprefs_set`, `userprefs_reset`, `userprefs_manifest`                                        |
+| Run the regression suite                          | `./mcp-server/run-tests.sh` (or `/test` slash command)                                                           |
+| Diagnose a specific device                        | `/diagnose [role]` slash command (read-only)                                                                     |
+| Triage a flaky test                               | `/repro <node-id> [count]` slash command                                                                         |
+
+**One MCP call per port at a time.** `SerialInterface` holds an exclusive OS-level lock on the serial port for its lifetime. If a `serial_*` session is open on `/dev/cu.usbmodem101`, calling `device_info` on the same port will fail fast pointing at the active session. Sequence calls: open → read/mutate → close, then next device. Never parallelize tool calls on the same port.
+
+### MCP tool surface (43 tools)
+
+Grouped by purpose. Full argument shapes in `mcp-server/README.md`; a few high-value signatures are called out here.
+
+- **Discovery & metadata**: `list_devices`, `list_boards`, `get_board`
+- **Build & flash**: `build`, `clean`, `pio_flash`, `erase_and_flash` (ESP32 only), `update_flash` (ESP32 OTA), `touch_1200bps`
+- **Serial sessions** (long-running, 10k-line ring buffer): `serial_open`, `serial_read`, `serial_list`, `serial_close`
+- **Device reads**: `device_info`, `list_nodes`
+- **Device writes**: `set_owner`, `get_config`, `set_config`, `get_channel_url`, `set_channel_url`, `send_text`, `send_input_event` (inject a button/key press via the firmware's InputBroker), `set_debug_log_api`; destructive/power-state writes require `confirm=True`: `reboot`, `shutdown`, `factory_reset`
+- **userPrefs admin** (build-time constants, not runtime config): `userprefs_get`, `userprefs_set`, `userprefs_reset`, `userprefs_manifest`, `userprefs_testing_profile`
+- **Vendor escape hatches**: `esptool_chip_info`, `esptool_erase_flash`, `esptool_raw`, `nrfutil_dfu`, `nrfutil_raw`, `picotool_info`, `picotool_load`, `picotool_raw`
+- **USB power control** (via `uhubctl`, per-port PPPS toggle): `uhubctl_list` (read-only), `uhubctl_power(action='on'|'off', confirm=True)`, `uhubctl_cycle(delay_s, confirm=True)`. Target by raw `(location, port)` or by `role` (`"nrf52"`, `"esp32s3"`); role lookup checks `MESHTASTIC_UHUBCTL_LOCATION_<ROLE>` + `_PORT_<ROLE>` env vars first, falls back to VID auto-detection.
+- **Observability** (UI tier + operator ad-hoc): `capture_screen(role, ocr=True)` — grabs a USB-webcam frame of the device OLED and optionally OCRs it. Requires `mcp-server[ui]` extras (`opencv-python-headless`, `easyocr`) and `MESHTASTIC_UI_CAMERA_DEVICE_<ROLE>` env var; falls through to a 1×1 black PNG `NullBackend` when unconfigured.
+
+`confirm=True` is a tool-level gate on top of whatever permission prompt your MCP host shows. **Don't bypass it** by asking the host to auto-approve — it exists specifically because MCP hosts sometimes remember "always allow this tool" and that's dangerous for `factory_reset`, `erase_and_flash`, `uhubctl_power(action='off')`, and `uhubctl_cycle`.
+
+**TCP / native-host nodes.** Setting `MESHTASTIC_MCP_TCP_HOST=<host[:port]>` makes `list_devices` surface a `meshtasticd` daemon (e.g. the `native-macos` build) as a synthetic `tcp://host:port` entry, and `connect()` routes through `meshtastic.tcp_interface.TCPInterface` instead of `SerialInterface`. Every read/write/admin tool that flows through `connect()` works against the daemon transparently. USB-only tools (`pio_flash`, `erase_and_flash`, `update_flash`, `touch_1200bps`, `serial_open`, `esptool_*`, `nrfutil_*`, `picotool_*`) raise a clear `ConnectionError` when handed a `tcp://` port; `pio_flash` against a `native*` env raises a `FlashError` (no upload step — use `build` and run the binary directly). The pytest harness still assumes USB-attached devices per role; TCP-aware fixtures are deferred. See `mcp-server/README.md` § "TCP / native-host nodes".
+
+### Hardware test suite (`mcp-server/run-tests.sh`)
+
+The wrapper auto-detects connected devices (VID → role map: `0x239A` → `nrf52`, `0x303A`/`0x10C4` → `esp32s3`), maps each role to a PlatformIO env (`nrf52` → `rak4631`, `esp32s3` → `heltec-v3`, overridable via `MESHTASTIC_MCP_ENV_<ROLE>`), then invokes pytest. Zero pre-flight config needed from the operator.
+
+Suite tiers (collected + run in this order via `pytest_collection_modifyitems`):
+
+1. `tests/unit/` — pure Python (boards parse, pio wrapper, userPrefs parse, testing profile, uhubctl parser). No hardware.
+2. `tests/test_00_bake.py` — flashes each detected device with current `userPrefs.jsonc` merged with the session's test profile. Has its own skip-if-already-baked check comparing region + primary channel to the session profile; skips cheaply on warm devices.
+3. `tests/mesh/` — multi-device mesh: bidirectional send, broadcast delivery, direct-with-ACK, mesh formation within 60s. Parametrized `[nrf52->esp32s3]` and `[esp32s3->nrf52]`. Includes `test_peer_offline_recovery` which uses uhubctl to physically power off one peer mid-conversation (requires uhubctl; skips without).
+4. `tests/telemetry/` — `DEVICE_METRICS_APP` broadcast timing.
+5. `tests/monitor/` — boot-log panic check.
+6. `tests/recovery/` — `uhubctl` power-cycle round-trip + NVS persistence across hard reset. Requires `uhubctl` installed and a PPPS-capable hub; entire tier auto-skips otherwise.
+7. `tests/ui/` — input-broker-driven screen navigation with camera + OCR evidence.
+8. `tests/fleet/` — PSK seed session isolation.
+9. `tests/admin/` — channel URL roundtrip, owner persistence across reboot.
+10. `tests/provisioning/` — region + modem + slot bake, admin key presence, `UNSET` region blocks TX, userPrefs survive factory reset.
+
+Invocation patterns:
+
+```bash
+./mcp-server/run-tests.sh                                        # full suite (auto-bake-if-needed)
+./mcp-server/run-tests.sh --force-bake                           # reflash before testing
+./mcp-server/run-tests.sh --assume-baked                         # skip bake (caller vouches for device state)
+./mcp-server/run-tests.sh tests/mesh                             # one tier
+./mcp-server/run-tests.sh tests/mesh/test_direct_with_ack.py     # one file
+./mcp-server/run-tests.sh -k telemetry                           # name filter
+```
+
+**No hardware detected?** The wrapper auto-narrows to `tests/unit/` only and prints `detected hub : (none)` in the pre-flight header. Agents interpreting the output should call this out explicitly — a 52-test green run without hardware is qualitatively different from a 12-unit-test green run.
+
+**Artifacts every run produces:**
+
+- `mcp-server/tests/report.html` — self-contained pytest-html. Each test gets a `Meshtastic debug` section with the tail of firmware log + device state dump. **Open this first** on failures; it's the canonical evidence source.
+- `mcp-server/tests/junit.xml` — CI-parseable.
+- `mcp-server/tests/reportlog.jsonl` — pytest-reportlog stream (`$report_type` keyed JSONL). Consumed by the live TUI.
+- `mcp-server/tests/fwlog.jsonl` — firmware log mirror from the `meshtastic.log.line` pubsub topic. Populated by the `_firmware_log_stream` autouse session fixture.
+
+### Live TUI (`meshtastic-mcp-test-tui`)
+
+A Textual-based live view that wraps `run-tests.sh`. Tails reportlog for per-test state, streams firmware logs, polls device state at startup + post-run (gated out of the active run because `hub_devices` holds exclusive port locks). Key bindings:
+
+| Key | Action                                                                                                       |
+| --- | ------------------------------------------------------------------------------------------------------------ |
+| `r` | re-run focused test (leaf → that node id; internal node → directory or `-k`)                                 |
+| `f` | filter tree by substring                                                                                     |
+| `d` | failure detail modal (pulls `longrepr` + captured stdout from the reportlog)                                 |
+| `g` | export reproducer bundle (tar.gz with README, test_report.json, time-filtered fwlog, devices.json, env.json) |
+| `l` | toggle firmware log pane                                                                                     |
+| `x` | tool coverage modal                                                                                          |
+| `c` | cross-run history sparkline                                                                                  |
+| `q` | quit (SIGINT → SIGTERM → SIGKILL escalation, 5-s windows each)                                               |
+
+Launch:
+
+```bash
+cd mcp-server
+.venv/bin/meshtastic-mcp-test-tui                 # full suite
+.venv/bin/meshtastic-mcp-test-tui tests/mesh      # args pass through to pytest
+```
+
+The plain CLI stays primary; the TUI is for operators who want a live dashboard. Both consume the same `run-tests.sh`.
+
+### Slash commands (Claude Code + Copilot)
+
+Three AI-assisted workflows wrap the test harness. Claude Code operators get `/test`, `/diagnose`, `/repro`; Copilot operators get `/mcp-test`, `/mcp-diagnose`, `/mcp-repro`. Bodies:
+
+- `.claude/commands/{test,diagnose,repro}.md`
+- `.github/prompts/mcp-{test,diagnose,repro}.prompt.md`
+
+`.claude/commands/README.md` is the index.
+
+House rules for agents running these prompts:
+
+- **Interpret failures, don't just echo them.** Pull firmware log tails from `report.html` and classify each failure as transient / environmental / regression. Use the exact format in `.claude/commands/test.md`.
+- **No destructive writes without operator approval.** Any skill that could reflash, factory-reset, or reboot a device must describe the action and stop. The operator authorizes.
+- **Sequential MCP calls per port.** See above.
+- **"Unknown" is a valid classification.** If evidence doesn't support a root cause, say so and list what would disambiguate. Do not invent.
+
+### Key fixtures (test authors + agents debugging)
+
+`mcp-server/tests/conftest.py` provides:
+
+- **`_session_userprefs`** (autouse session) — snapshots `userPrefs.jsonc` at session start, merges the session test profile via `userprefs.merge_active(test_profile)`, restores at teardown. Four layers of safety: pytest teardown + `atexit` + sidecar file (`userPrefs.jsonc.mcp-session-bak`) + startup self-heal in `run-tests.sh`. **Do not edit `userPrefs.jsonc` from inside a test.**
+- **`_firmware_log_stream`** (autouse session) — subscribes to `meshtastic.log.line` pubsub on every connected `SerialInterface` and mirrors lines to `tests/fwlog.jsonl`. Drives the TUI firmware-log pane.
+- **`_debug_log_buffer`** (autouse per-test) — captures last 200 firmware log lines + device state for attachment to the pytest-html `Meshtastic debug` section on failure.
+- **`hub_devices`** (session) — `dict[role, SerialInterface]` with session-long exclusive port locks. Reason the TUI's device poller is gated to startup + post-run only.
+- **`baked_mesh`** — parametrized mesh-pair fixture; depends on `test_00_bake`. `pytest_generate_tests` in `conftest.py` auto-generates `[nrf52->esp32s3]` and `[esp32s3->nrf52]` variants.
+- **`test_profile`** — session-scoped dict: region, primary channel, admin key, PSK seed. Derived from `MESHTASTIC_MCP_SEED` (defaults to `mcp-<user>-<host>`).
+
+### Firmware integration points tied to the test harness
+
+Two firmware changes exist specifically so the test harness works reliably. **Keep these in mind when touching related code.**
+
+- **`src/mesh/StreamAPI.cpp` + `StreamAPI.h`** — `emitLogRecord` uses a dedicated `fromRadioScratchLog` + `txBufLog` pair and a `concurrency::Lock streamLock`. Before this fix, `debug_log_api_enabled=true` would tear `FromRadio` protobufs on the serial transport because `emitTxBuffer` and `emitLogRecord` shared a single scratch buffer. The conftest enables the log stream session-wide; without this fix the device would corrupt its own FromRadio replies mid-session.
+- **`src/mesh/PhoneAPI.cpp`** — `ToRadio` `Heartbeat(nonce=1)` triggers `nodeInfoModule->sendOurNodeInfo(NODENUM_BROADCAST, true, 0, true)` for serial clients, mirroring the pre-existing behavior for TCP/UDP clients in `PacketAPI.cpp`. The mesh tests rely on this to force a NodeInfo broadcast right after connect so the peer discovers them before the test's first assertion.
+
+If you're modifying `StreamAPI`, `PhoneAPI`, `NodeInfoModule`, or `userPrefs` flow, run `./mcp-server/run-tests.sh` at minimum before asking for review.

+### Never do these without asking
+
+- `factory_reset` — wipes node identity; regenerates PKI keypair. Mesh peers will reject old DMs until re-exchange. Legitimate only when the operator explicitly wants it.
+- `erase_and_flash` — full chip erase; destroys all on-device state.
+- `esptool_erase_flash` / `esptool_raw` write/erase — bypasses pio's safety chain.
+- `set_config` on `lora.region` — changes regulatory domain; requires physical-location context the operator has and the agent doesn't.
+- `reboot` / `shutdown` mid-test — breaks fixture invariants.
+- `push -f`, `rebase -i`, `reset --hard`, or any history-rewriting git operation.
+- Clicking computer-use tools on web links in Mail/Messages/PDFs — open URLs via the claude-in-chrome MCP so the extension's link-safety checks apply.

+description: Device health report via the meshtastic MCP tools (Copilot equivalent of the Claude Code /diagnose slash command)
+---
+
+# `/mcp-diagnose` — device health report
+
+Equivalent of `.claude/commands/diagnose.md`. Use when the operator asks to "check the devices", "what's the mesh looking like", "is nrf52 alive", etc.
+
+This prompt assumes the meshtastic MCP server is registered with your VS Code Copilot agent. If it isn't, fall back to running `./mcp-server/run-tests.sh tests/unit` plus a short `device_info` script via the terminal.
+
+## What to do
+
+1. **Enumerate hardware** via the `list_devices` MCP tool (with `include_unknown=True`). For each entry where `likely_meshtastic=True`, capture `port`, `vid`, `pid`, `description`.
+
+2. **Apply the operator's filter** (if any):
+   - No filter → every likely-meshtastic device.
+   - `nrf52` → `vid == 0x239a`
+   - `esp32s3` → `vid == 0x303a` or `vid == 0x10c4`
+   - A `/dev/cu.*` path → only that port.
+   - Anything else → substring match on port.
+
+3. **For each selected device, in sequence (don't parallelize — SerialInterface holds an exclusive port lock):**
+   - `device_info(port=<p>)` → `my_node_num`, `long_name`, `short_name`, `firmware_version`, `hw_model`, `region`, `num_nodes`, `primary_channel`
+   - `list_nodes(port=<p>)` → peer count, which peers have `publicKey`, SNR/RSSI distribution
+   - `get_config(section="lora", port=<p>)` → region, preset, channel_num, tx_power, hop_limit
+   - If anything looks off (can't connect, `num_nodes` wrong, missing `firmware_version`), open a short firmware-log window: `serial_open(port=<p>, env=<inferred>)`, wait 3 seconds, `serial_read(session_id, max_lines=100)`, `serial_close(session_id)`. Infer env from VID (0x239a → `rak4631`, 0x303a/0x10c4 → `heltec-v3`) unless an `MESHTASTIC_MCP_ENV_<ROLE>` env var overrides it.
+
+4. **Hub health** (call once, not per-device): `uhubctl_list()` — enumerates every USB hub the host sees. Cross-reference each Meshtastic device's VID to find which hub + port it's on. Flag in the report if:
+   - No hub advertises `ppps=true` → `tests/recovery/` can't run; hard-recovery via `uhubctl_cycle` isn't available.
+   - A Meshtastic device is on a non-PPPS hub → note it; moving to a PPPS hub unlocks auto-recovery.
+   - `uhubctl_list` raises `ConfigError: uhubctl not found` → report as "uhubctl not installed"; don't treat as a device fault.
+
+5. **Render per-device report** as a compact block:
+
+   ```text
+   [nrf52 @ /dev/cu.usbmodem1101]      fw=2.7.23.bce2825, hw=RAK4631
+     owner       : Meshtastic 40eb / 40eb
+     region/band : US, channel 88, LONG_FAST
+     tx_power    : 30 dBm, hop_limit=3
+     peers       : 1 (esp32s3 0x433c2428, pubkey ✓, SNR 6.0 / RSSI -24 dBm)
+     primary ch  : McpTest
+     hub         : 1-1.3 port 2 (PPPS, uhubctl-controllable)
+     firmware    : no panics in last 3s
+   ```
+
+   Flag abnormalities inline with `⚠︎ <short reason>` — missing pubkey on a known peer, region UNSET, mismatched channel name, device on non-PPPS hub, etc.
+
+6. **Cross-device correlation** (when >1 device selected):
+   - Do both see each other in `nodesByNum`?
+   - Do `region`, `channel_num`, `modem_preset` match across devices?
+   - Do the primary channel names match? (Different name → different PSK → no decode.)
+
+7. **Suggest next steps only for recognizable failure modes**, never speculatively:
+   - Stale PKI one-way → "`/mcp-test tests/mesh/test_direct_with_ack.py` — the test's retry+nodeinfo-ping heals this."
+   - Region mismatch → "re-bake one side via `./mcp-server/run-tests.sh --force-bake`."
+   - Device unreachable, DFU reachable → `touch_1200bps(port=...)` + `pio_flash`. If not even DFU responds and the device is on a PPPS hub, escalate to `uhubctl_cycle(role=..., confirm=True)`.
+   - CP2102-wedged-driver on macOS → see `run-tests.sh` notes.
+
+## Hard constraints
+
+- **Read-only.** No `set_config`, no `reboot`, no `factory_reset`, no `flash`. If the operator wants mutation, they'll escalate explicitly.
+- **Open/query/close per device.** Never hold multiple SerialInterfaces to the same port. The port lock is exclusive.
+- **Don't infer env beyond the VID map** — if the operator has an unusual board, ask them which env to use rather than guessing.

+description: Re-run a specific test N times to triage flakes; diff firmware logs between passes and failures (Copilot equivalent of the Claude Code /repro slash command)
+---
+
+# `/mcp-repro` — flakiness triage for one test
+
+Equivalent of `.claude/commands/repro.md`. Use when the operator says "that one test is flaky — dig in", "repro the direct_with_ack failure", "why does X sometimes fail?".
+
+## What to do
+
+1. **Parse the operator's input** into two pieces:
+   - **Test identifier** — either a pytest node id (has `::` or starts with `tests/`) or a `-k`-style filter (plain substring like `direct_with_ack`).
+   - **Count** — integer, default `5`, cap at `20`. If the operator asks for 50, negotiate down and explain (airtime + USB wear).
+
+2. **Sanity-check the hub** via the `list_devices` MCP tool. If the test name references `nrf52` or `esp32s3` and the matching VID isn't present, stop and report — re-running won't help.
+
+3. **Loop** N times. Each iteration:
+
+   ```bash
+   ./mcp-server/run-tests.sh <test-id> --tb=short -p no:cacheprovider
+   ```
+
+   `-p no:cacheprovider` keeps pytest from caching anything between iterations. Capture: exit code, duration, and (on failure) the `Meshtastic debug` firmware-log section from `mcp-server/tests/report.html`.
+
+4. **Tally** results as you go:
+
+   ```text
+   attempt 1: PASS (42s)
+   attempt 2: FAIL (128s)    ← fw log captured
+   attempt 3: PASS (39s)
+   attempt 4: FAIL (121s)
+   attempt 5: PASS (41s)
+   --------------------------------------------------
+   pass rate: 3/5 (60%)  |  mean duration: 74s
+   ```
+
+5. **On mixed outcomes, diff the firmware logs** between one representative pass and one representative fail. Focus on:
+   - Error-level lines present only in failures (`PKI_UNKNOWN_PUBKEY`, `Alloc an err=`, `Skip send`, `No suitable channel`, `NAK`)
+   - Timing around the assertion point (broadcast sent? ACK received? retry fired?)
+   - Device-state fields that changed between attempts
+
+   Surface the top 3 differences as a compact "passes when / fails when" table with uptime timestamps. Don't dump full logs.
+
+6. **Classify** the flake into one of:
+   - **LoRa airtime collision** — pass rate improves with fewer concurrent transmitters. Suggest a `time.sleep` gap or retry bump in the test body.
+   - **PKI key staleness** — first attempt fails, subsequent ones pass; existing retry-loop pattern in `test_direct_with_ack.py` is the fix.
+   - **NodeInfo cooldown** — `Skip send NodeInfo since we sent it <600s ago` in fail-only logs; needs a `broadcast_nodeinfo_ping()` warmup.
+   - **Hardware-specific** — one direction consistently fails, firmware versions differ, CP2102 driver wedged, etc. For a device wedged past `touch_1200bps`, recommend `uhubctl_cycle(role=..., confirm=True)` to hard-power-cycle its hub port (requires `uhubctl` installed).
+   - **Device went dark mid-run** — fails from some iteration onward and never recovers; firmware log stops arriving. Almost always a Guru crash with frozen CDC. Recommend `uhubctl_cycle` before the next iteration; escalate to replug if that also fails.
+   - **Unknown** — say so. Don't invent a root cause.
+
+7. **Report back** with:
+   - Pass rate + mean duration.
+   - Classification + the specific log evidence for it.
+   - A concrete next step (tighter assertion, more retries, open `/mcp-diagnose`, file a bug, nothing).
+
+## Examples
+
+- `tests/mesh/test_direct_with_ack.py::test_direct_with_ack_roundtrip[esp32s3->nrf52] 10` — 10 runs of that parametrized case.
+- `broadcast_delivers` — no `::`, no `tests/`; treat as `-k broadcast_delivers`; runs every match 5 times.
+- `tests/telemetry/test_device_telemetry_broadcast.py 3` — shorter count for a slow test.
+
+## Notes
+
+- If the FIRST attempt fails and the rest pass, that's a state-leak signature — suggest starting from `--force-bake` or a clean device state rather than chasing the first-failure firmware logs.
+- If ALL N fail, this isn't a flake — it's a regression. Say so, stop iterating, escalate to `/mcp-test` for full-suite context.
+- Don't rebuild firmware during triage. Flakes that only reproduce under different firmware belong in a separate session with a plan.

+description: Run the mcp-server test suite and interpret results (Copilot equivalent of the Claude Code /test slash command)
+---
+
+# `/mcp-test` — mcp-server test runner with interpretation
+
+Equivalent of the Claude Code `/test` slash command in `.claude/commands/test.md`. Use this when the operator asks you to "run the tests", "check the mcp test suite", "run the mesh tests", etc.
+
+## What to do
+
+1. **Invoke the wrapper** from the firmware repo root:
+
+   ```bash
+   ./mcp-server/run-tests.sh [pytest-args]
+   ```
+
+   If the operator specified a subset (e.g. "just the mesh tests"), pass it through as `tests/mesh` or a pytest `-k filter`. If they said nothing, use the wrapper's defaults (full suite with pytest-html report).
+
+   The wrapper auto-detects connected Meshtastic devices, maps each to its PlatformIO env, exports the required env vars, and invokes pytest. Zero pre-flight config needed from the operator.
+
+2. **Read the pre-flight header** (first few lines of wrapper output). The `detected hub :` line lists role → port → env mappings. If it reads `(none)`, the wrapper narrowed to `tests/unit` only — call that out explicitly so the operator knows hardware tiers were skipped.
+
+3. **On pass**: one-line summary like `N passed, M skipped in <duration>`. Don't enumerate test names. DO mention any non-placeholder SKIPs and name the cause:
+   - `"role not present on hub"` → device unplugged; operator should reconnect.
+   - `"firmware not baked with USERPREFS_UI_TEST_LOG"` → tests/ui skipped; the UI-log compile macro isn't in the baked firmware. Suggest `--force-bake`.
+   - `"uhubctl not installed"` → tests/recovery + `test_peer_offline_recovery` skipped. Suggest `brew install uhubctl` / `apt install uhubctl`.
+   - `"no PPPS-capable hubs detected"` → tests/recovery skipped because the attached hub doesn't support per-port power switching; won't run on that setup.
+   - `"opencv-python-headless is not installed"` → tests/ui auto-deselected by `run-tests.sh`. Suggest `pip install -e 'mcp-server/.[ui]'`.
+
+4. **On failure**: open `mcp-server/tests/report.html` (pytest-html output, self-contained) and extract the `Meshtastic debug` section for each failed test. That section includes a firmware log stream (last 200 lines) and device state dump. For each failure, summarise:
+   - test name
+   - one-line assertion message
+   - the specific firmware log lines that explain why (look for `PKI_UNKNOWN_PUBKEY`, `Skip send NodeInfo`, `Error=`, `Guru Meditation`, `assertion failed`, `No suitable channel`)
+   - for UI-tier failures also check `mcp-server/tests/ui_captures/<session>/<test>/transcript.md` (per-step frame + OCR)
+
+5. **Classify each failure** as one of:
+   - **Transient flake** — LoRa collision, first-attempt NAK with self-heal pattern, timing-sensitive assertion. Suggest `/mcp-repro <test-id>` to confirm.
+   - **Environmental** — device unreachable, port busy, CP2102 driver wedged on macOS. Suggest recovery in escalation order: (a) replug USB, (b) `touch_1200bps` + `pio_flash` for nRF52 DFU, (c) `uhubctl_cycle(role=..., confirm=True)` for a device wedged past DFU (needs `uhubctl` installed; `baked_single` does this once automatically when available). Also check `git status userPrefs.jsonc`.
+   - **Regression** — same assertion fails repeatedly on re-runs, firmware log shows novel errors. Identify the firmware module likely responsible.
+
+6. **Do NOT run destructive recovery automatically**. If a failure looks like it needs a reflash, factory*reset, `uhubctl_cycle`, or replug — \_describe the steps* and let the operator decide. Never burn airtime or flash cycles without approval.
+
+## Arguments convention
+
+Operators generally invoke this prompt either with no arguments (full suite) or with a specific subset. Examples:
+
+- `tests/mesh` — one tier
+- `tests/mesh/test_direct_with_ack.py::test_direct_with_ack_roundtrip` — one test
+- `--force-bake` — reflash devices first
+- `-k telemetry` — name-filter
+
+## Side-effects to confirm in your summary
+
+- `userPrefs.jsonc` should be clean after a successful run. The session fixture in `mcp-server/tests/conftest.py` (`_session_userprefs`) snapshots and restores. Check `git status --porcelain userPrefs.jsonc` and report if it's non-empty.
+- `mcp-server/tests/report.html` and `junit.xml` regenerate on every run.
+- The wrapper prints a warning if a `.mcp-session-bak` sidecar was left over from a crashed prior session and auto-restores from it — mention that if it happened.

+# New Meshtastic Module
+
+Guide for developing a new Meshtastic firmware module.
+
+## Module Hierarchy
+
+Choose the appropriate base class:
+
+1. **`MeshModule`** — Raw base class. Override `wantPacket()` and `handleReceived()`. Returns `ProcessMessage::STOP` or `ProcessMessage::CONTINUE`.
+2. **`SinglePortModule`** — Handles a single `meshtastic_PortNum`. Constructor takes `(name, portNum)`. Simplified `wantPacket()` checking `decoded.portnum`. Use `allocDataPacket()` to create outgoing packets.
+3. **`ProtobufModule<T>`** — Template for protobuf-encoded modules. Constructor takes `(name, portNum, fields)`. Override `handleReceivedProtobuf()`. Use `allocDataProtobuf(payload)` to create outgoing packets.
+
+Most modules also mix in `concurrency::OSThread` for periodic background tasks.
+
+## Implementation Pattern
+
+```cpp
+// src/modules/MyModule.h
+#pragma once
+#include "ProtobufModule.h"
+#include "concurrency/OSThread.h"
+
+class MyModule : public ProtobufModule<meshtastic_MyMessage>, private concurrency::OSThread
+{
+  public:
+    MyModule();
+
+  protected:
+    // Process incoming protobuf packet. Return true to stop further processing.
+    virtual bool handleReceivedProtobuf(const meshtastic_MeshPacket &mp, meshtastic_MyMessage *msg) override;
+
+    // Generate response packet (optional)
+    virtual meshtastic_MeshPacket *allocReply() override;
+
+    // Periodic task — return next run interval in ms, or disable()
+    virtual int32_t runOnce() override;
+
+    // Modify packet in-flight before delivery (optional)
+    virtual bool alterReceivedProtobuf(meshtastic_MeshPacket &mp, meshtastic_MyMessage *msg);
+
+    // Request a UI display frame (optional)
+    virtual bool wantUIFrame();
+};
+```
+
+## Registration
+
+Register in `src/modules/Modules.cpp` inside `setupModules()`:
+
+```cpp
+#if !MESHTASTIC_EXCLUDE_MYMODULE
+    new MyModule();
+#endif
+```
+
+If other code needs to reference the module instance:
+
+```cpp
+#if !MESHTASTIC_EXCLUDE_MYMODULE
+    myModule = new MyModule();
+#endif
+```
+
+And declare the global in the header:
+
+```cpp
+extern MyModule *myModule;
+```
+
+Some modules also conditionally instantiate based on `moduleConfig`:
+
+```cpp
+#if !MESHTASTIC_EXCLUDE_MYMODULE
+    if (moduleConfig.has_my_module && moduleConfig.my_module.enabled) {
+        new MyModule();
+    }
+#endif
+```
+
+## Conditional Compilation
+
+Add a `MESHTASTIC_EXCLUDE_MYMODULE` guard. This allows the module to be excluded from constrained builds. The flag name must follow the pattern: `MESHTASTIC_EXCLUDE_` + uppercase module name.
+
+## Protobuf Messages (if needed)
+
+1. Define messages in `protobufs/meshtastic/` (e.g., `mymodule.proto`)
+2. Add a `.options` file for nanopb field size constraints
+3. Regenerate with `bin/regen-protos.sh`
+4. Generated code appears in `src/mesh/generated/meshtastic/`
+5. Assign a `meshtastic_PortNum` if the module uses a new port number
+
+## Timing and Defaults
+
+Use `Default` class helpers for configurable intervals:
+
+```cpp
+int32_t MyModule::runOnce()
+{
+    uint32_t interval = Default::getConfiguredOrDefaultMs(moduleConfig.my_module.update_interval,
+                                                          default_my_module_interval);
+    // ... do work ...
+    return interval;
+}
+```
+
+On public/default channels, enforce minimums with `Default::getConfiguredOrMinimumValue()`.
+
+## Observer Pattern
+
+Subscribe to system events:
+
+```cpp
+CallbackObserver<MyModule, const meshtastic::Status *> statusObserver =
+    CallbackObserver<MyModule, const meshtastic::Status *>(this, &MyModule::handleStatusUpdate);
+```
+
+## Testing
+
+Add test suite in `test/test_mymodule/`:
+
+```text
+test/
+└── test_mymodule/
+    └── test_main.cpp
+```
+
+Run with: `pio test -e native`

+# New Telemetry Sensor
+
+Guide for adding a new I2C telemetry sensor driver to Meshtastic firmware.
+
+## Overview
+
+Telemetry sensors live in `src/modules/Telemetry/Sensor/`. There are 50+ existing drivers organized by measurement type. Each sensor integrates with one of the telemetry modules:
+
+- **EnvironmentTelemetryModule** — Temperature, humidity, pressure, gas, light
+- **AirQualityTelemetryModule** — Particulate matter, VOCs
+- **PowerTelemetryModule** — Voltage, current, power monitoring
+- **HealthTelemetryModule** — Heart rate, SpO2, body temperature
+
+## Sensor Driver Pattern
+
+Each sensor has a `.h` and `.cpp` file pair following this pattern:
+
+```cpp
+// src/modules/Telemetry/Sensor/MySensor.h
+#pragma once
+#include "TelemetrySensor.h"
+#include <MySensorLibrary.h>  // Arduino/PlatformIO library
+
+class MySensor : virtual public TelemetrySensor
+{
+  private:
+    MySensorLibrary sensor;
+
+  public:
+    MySensor() : TelemetrySensor(meshtastic_TelemetrySensorType_MY_SENSOR, "MySensor") {}
+
+    // Initialize sensor hardware. Return true on success.
+    virtual void setup() override;
+
+    // Read sensor data into the telemetry protobuf. Return true on success.
+    virtual bool getMetrics(meshtastic_Telemetry *measurement) override;
+};
+```
+
+```cpp
+// src/modules/Telemetry/Sensor/MySensor.cpp
+#include "MySensor.h"
+#include "TelemetrySensor.h"
+
+void MySensor::setup()
+{
+    sensor.begin();
+    // Configure sensor parameters...
+}
+
+bool MySensor::getMetrics(meshtastic_Telemetry *measurement)
+{
+    // Read from hardware
+    float value = sensor.readValue();
+
+    // Populate the appropriate protobuf variant
+    measurement->variant.environment_metrics.temperature = value;
+    // ... other fields ...
+
+    return true;
+}
+```
+
+## I2C Address Registration
+
+Register the sensor's I2C address(es) in `src/detect/ScanI2C` so it's auto-detected at boot:
+
+1. Add a `DeviceType` enum entry in `src/detect/ScanI2C.h`
+2. Add the I2C address mapping in `src/detect/ScanI2CTwoWire.cpp`
+
+The scan runs at boot and populates a device map that telemetry modules use to decide which sensors to initialize.
+
+## Protobuf Fields
+
+If the sensor provides data not covered by existing telemetry fields:
+
+1. Add fields to the appropriate message in `protobufs/meshtastic/telemetry.proto`:
+   - `EnvironmentMetrics` — Environmental measurements
+   - `AirQualityMetrics` — Air quality data
+   - `PowerMetrics` — Power/energy data
+   - `HealthMetrics` — Health/biometric data
+2. Add a `.options` constraint if needed (field sizes for nanopb)
+3. Regenerate: `bin/regen-protos.sh`
+
+## Sensor Type Enum
+
+Add the sensor to `meshtastic_TelemetrySensorType` enum in `protobufs/meshtastic/telemetry.proto`:
+
+```protobuf
+enum TelemetrySensorType {
+    // ... existing entries ...
+    MY_SENSOR = XX;
+}
+```
+
+## Integration with Telemetry Module
+
+Wire the sensor into the appropriate telemetry module. For environment sensors, this is typically in `src/modules/Telemetry/EnvironmentTelemetry.cpp`:
+
+1. Include the sensor header
+2. Add initialization in `setupSensor()` guarded by detection results
+3. Call `getMetrics()` in the measurement collection path
+
+Example pattern from existing sensors:
+
+```cpp
+#include "Sensor/MySensor.h"
+
+MySensor mySensor;
+
+// In setup:
+if (nodeTelemetrySensorsMap[meshtastic_TelemetrySensorType_MY_SENSOR].first > 0) {
+    mySensor.setup();
+}
+
+// In measurement collection:
+if (nodeTelemetrySensorsMap[meshtastic_TelemetrySensorType_MY_SENSOR].first > 0) {
+    mySensor.getMetrics(&measurement);
+}
+```
+
+## Library Dependencies
+
+If the sensor needs an external library, add it to the `lib_deps` in the relevant base platformio.ini configs:
+
+```ini
+lib_deps =
+    ${env.lib_deps}
+    mysensorlibrary@^1.0.0
+```
+
+Or use a conditional dependency if it's platform-specific.
+
+## Unit Conversions
+
+If the sensor reports values in non-standard units, use `src/modules/Telemetry/UnitConversions.h` for conversion helpers (e.g., Celsius ↔ Fahrenheit, hPa ↔ inHg).
+
+## Checklist
+
+- [ ] Create `src/modules/Telemetry/Sensor/MySensor.h` and `.cpp`
+- [ ] Inherit from `TelemetrySensor` base class
+- [ ] Implement `setup()` and `getMetrics()` methods
+- [ ] Add `meshtastic_TelemetrySensorType` enum entry in `telemetry.proto`
+- [ ] Add I2C address to `src/detect/ScanI2C` for auto-detection
+- [ ] Add protobuf fields in `telemetry.proto` if new data types needed
+- [ ] Regenerate protos: `bin/regen-protos.sh`
+- [ ] Wire into the appropriate telemetry module (Environment/AirQuality/Power/Health)
+- [ ] Add library dependency if external library required
+- [ ] Test on hardware or native build

+### Common Base Configs
+
+- `esp32_base` / `esp32-common.ini` — ESP32
+- `esp32s3_base` — ESP32-S3
+- `esp32c3_base` — ESP32-C3
+- `esp32c6_base` — ESP32-C6
+- `nrf52840_base` / `nrf52.ini` — nRF52840
+- `rp2040_base` — RP2040/RP2350
+
+### Support Levels
+
+- `custom_meshtastic_support_level = 1` — Built on every PR (actively supported)
+- `custom_meshtastic_support_level = 2` — Built only on merge to main branches
+- `board_level = extra` — Only built on full releases
+
+## Build Manifest Metadata
+
+`bin/platformio-custom.py` emits UI capability flags in the build manifest:
+
+- `custom_meshtastic_has_mui = true/false` — Override MUI detection
+- `custom_meshtastic_has_ink_hud = true/false` — Override InkHUD detection
+- Architecture names are normalized (e.g., `esp32s3` → `esp32-s3`)
+
+## InkHUD E-Ink Variants
+
+For e-ink display variants using the InkHUD framework, add `nicheGraphics.h`:
+
+```cpp
+// nicheGraphics.h — InkHUD configuration for this variant
+#define INKHUD                     // Enable InkHUD
+// Configure display, applets, and refresh behavior per device
+```
+
+InkHUD has its own PlatformIO config: `src/graphics/niche/InkHUD/PlatformioConfig.ini`
+
+## I2C Device Detection
+
+If the variant has I2C devices, ensure `src/detect/ScanI2C` will detect them. The auto-detection system handles 80+ device types including displays, sensors, RTCs, keyboards, PMUs, and touch controllers at boot.
+
+## Custom Board Definitions
+
+If the PlatformIO board doesn't exist, create a custom board JSON in `boards/`:
+
+```json
+{
+  "build": {
+    "arduino": { "ldscript": "esp32s3_out.ld" },
+    "core": "esp32",
+    "f_cpu": "240000000L",
+    "f_flash": "80000000L",
+    "flash_mode": "qio",
+    "mcu": "esp32s3",
+    "variant": "esp32s3"
+  },
+  "connectivity": ["wifi", "bluetooth"],
+  "frameworks": ["arduino", "espidf"],
+  "name": "My Custom Board",
+  "upload": {
+    "flash_size": "8MB",
+    "maximum_ram_size": 327680,
+    "maximum_size": 8388608
+  },
+  "url": "https://example.com",
+  "vendor": "MyVendor"
+}
+```
+

+
+            If you have ideas for features, note that we often debate big ideas
+            in the [discussions tab](https://github.com/meshtastic/firmware/discussions/categories/ideas)
+            first. This tracker tends to be for ideas that have community
+            consensus and a clear implementation.
+
+            We're very active [on discord](https://discord.com/invite/meshtastic),
+            especially the \#firmware and \#alphanauts-testing channels. If you'll
+            be around for a while, we'd love to see you there!

+
+            IMPORTANT: Distinguish between:
+            - Device/firmware bugs (crashes, reboots, lockups, radio/GPS/display/power issues) - these need device logs
+            - Build/release/packaging issues (missing files, CI failures, download problems) - these do NOT need device logs
+            - Documentation or website issues - these do NOT need device logs
+
+            If this is a device/firmware bug, request device logs and explain how to get them:
+
+            Web Flasher logs:
+            - Go to https://flasher.meshtastic.org
+            - Connect the device via USB and click Connect
+            - Open the device console/log output, reproduce the problem, then copy/download and attach/paste the logs
+
+            Meshtastic CLI logs:
+            - Run: meshtastic --port <serial-port> --noproto
+            - Reproduce the problem, then copy/paste the terminal output
+
+            Also request key context if missing: device model/variant, firmware version, region, steps to reproduce, expected vs actual.
+
+            Respond ONLY with valid JSON (no markdown, no code fences):
+            {"complete": true, "comment": "", "label": "none"}
+            OR
+            {"complete": false, "comment": "Your helpful comment", "label": "needs-logs"}
+
+            Use "needs-logs" ONLY if this is a device/firmware bug AND no logs are attached.
+            Use "needs-info" if basic info like firmware version or steps to reproduce are missing.
+            Use "none" if the issue is complete, is a feature request, or is a build/CI/packaging issue.

+# Agent instructions
+
+This repository is the [Meshtastic](https://meshtastic.org) firmware — a C++17 embedded codebase targeting ESP32 / nRF52 / RP2040 / STM32WL / Linux-Portduino LoRa mesh radios — plus a Python MCP server in `mcp-server/` that AI agents use to flash, configure, and test connected devices.
+
+## Primary instruction file
+
+**Read `.github/copilot-instructions.md` first.** That file is the canonical agent-facing document for this repo. It covers project layout, coding conventions (naming, module framework, Observer pattern, thread safety), the build system, CI/CD, the native C++ test suite, and — most importantly for automation work — the **MCP Server & Hardware Test Harness** section. Read it top-to-bottom before starting any non-trivial change.
+
+This file (`AGENTS.md`) is a short pointer + quick reference for agents that don't read `.github/copilot-instructions.md` by default.

+## MCP server (device + test automation)
+
+The `mcp-server/` package exposes ~32 MCP tools for device discovery, building, flashing, serial monitoring, and live-node administration. Tools are grouped as:
+
+- **Discovery**: `list_devices`, `list_boards`, `get_board`
+- **Build & flash**: `build`, `clean`, `pio_flash`, `erase_and_flash` (ESP32 factory), `update_flash` (ESP32 OTA), `touch_1200bps`
+- **Serial sessions**: `serial_open`, `serial_read`, `serial_list`, `serial_close`
+- **Device reads**: `device_info`, `list_nodes`
+- **Device writes** (require `confirm=True`): `set_owner`, `get_config`, `set_config`, `get_channel_url`, `set_channel_url`, `send_text`, `reboot`, `shutdown`, `factory_reset`, `set_debug_log_api`
+- **userPrefs admin**: `userprefs_get`, `userprefs_set`, `userprefs_reset`, `userprefs_manifest`, `userprefs_testing_profile`
+- **Vendor escape hatches**: `esptool_*`, `nrfutil_*`, `picotool_*`
+
+Setup: `cd mcp-server && python3 -m venv .venv && .venv/bin/pip install -e '.[test]'`. The repo registers the server via `.mcp.json` — Claude Code picks it up automatically.

+See `mcp-server/README.md` for argument shapes and the **MCP Server & Hardware Test Harness** section of `.github/copilot-instructions.md` for agent usage rules (tool surface, fixture contract, firmware integration points, recovery playbooks).
+
+## Slash commands (AI-assisted workflows)
+
+Three test-and-diagnose workflows exist as slash commands:
+
+- **`/test` (Claude Code) / `/mcp-test` (Copilot)** — run the hardware test suite and interpret failures
+- **`/diagnose` / `/mcp-diagnose`** — read-only device health report
+- **`/repro` / `/mcp-repro`** — flakiness triage: re-run one test N times, diff firmware logs between passes and failures
+
+Bodies live in `.claude/commands/` and `.github/prompts/` respectively. `.claude/commands/README.md` is the index.
+
+## Encryption at a glance
+
+Two layers, both in `src/mesh/CryptoEngine.cpp`:
+
+- **Channel (symmetric)** — **AES-CTR** with a channel-wide PSK (AES-128 or AES-256). Nonce = packet_id ‖ from_node ‖ block_counter. No AEAD; integrity is soft (channel-hash filter). The well-known default PSK lives in `src/mesh/Channels.h`; a 1-byte PSK is a short-form index into it.
+- **Per-peer PKI** — **X25519 ECDH** (Curve25519, 32-byte keys) → SHA-256 → **AES-256-CCM** with an 8-byte MAC. Fresh 32-bit `extraNonce` per packet, sent in the clear alongside the MAC. 12-byte wire overhead (`MESHTASTIC_PKC_OVERHEAD`). Used for DMs. Also used for remote admin (`src/modules/AdminModule.cpp`), where AdminMessage authorization is gated by `config.security.admin_key[0..2]`. Disabled entirely in Ham mode (`user.is_licensed=true`).
+
+Key rotation to never trigger casually: only the **full** factory reset (`factory_reset_device`, `eraseBleBonds=true`) wipes `security.private_key` and regenerates the keypair — every peer holds the old public key, so DMs silently fail PKI decrypt until NodeInfo re-exchanges. The **partial** config reset (`factory_reset_config`) preserves the private key and doesn't invalidate peer relationships. Explicitly blanking `security.private_key` via admin also triggers regen. See the **Encryption & Key Management** section of `.github/copilot-instructions.md` for the full spec (nonce layout, send/receive selection logic including infrastructure-portnum exceptions, admin-key + session-passkey authorization, `is_managed` scope, key-rotation hazards).
+
+## House rules
+
+- **No destructive device operations without operator approval.** `factory_reset`, `erase_and_flash`, `reboot`, `shutdown`, history-rewriting git ops — describe the action and stop. Operator authorizes.
+- **One MCP call per serial port at a time.** The port lock is exclusive; concurrent calls deadlock. Sequence: open → read/mutate → close, then next device.
+- **`userPrefs.jsonc` is session state during tests.** The `_session_userprefs` fixture snapshots + restores it; never edit it from inside a test.
+- **Don't speculate about firmware root causes.** When evidence doesn't support a classification, say "unknown" and list what would disambiguate.
+- **Run `trunk fmt` before proposing a commit.** The `trunk_check` CI gate will reject unformatted code. Claude Code runs it automatically via the PostToolUse hook in `.claude/settings.json`; trunk's launcher needs `curl` or `wget` to bootstrap its pinned CLI — see **Formatting & the trunk toolchain** in `.github/copilot-instructions.md` for the no-curl bootstrap procedure.
+- **`confirm=True` on destructive MCP tools is a real gate, not a formality.** Don't bypass it via auto-approve settings.
+- **Keep code comments minimal — one or two lines, max.** Comment only when the _why_ isn't obvious from the code; never restate what the next line does. No multi-paragraph block comments explaining straightforward changes. The diff and commit message carry the rationale; the code carries the behavior.
+- **Use `Throttle` for time-based rate limiting, not raw `millis()` math.** `src/mesh/Throttle.h` provides `Throttle::isWithinTimespanMs(lastMs, intervalMs)` (returns true while inside the cooldown) and `Throttle::execute(&lastMs, intervalMs, func)` (function-pointer form that updates the timestamp on fire). Use these for any "did N ms pass since X" check — raw `millis() > lastMs + N` is rollover-unsafe (breaks after ~49.7 days) and inconsistent with the rest of the codebase. The helpers compute `now - lastMs` with unsigned subtraction, which wraps correctly.
+
+## Typical agent workflows
+
+### Flashing a device
+
+1. `list_devices` → find the port + likely VID
+2. `list_boards` → confirm the env, or use the known default for the hardware
+3. `pio_flash(env=..., port=..., confirm=True)` for any arch, or `erase_and_flash(env=..., port=..., confirm=True)` for an ESP32 factory install
+
+### Inspecting live node state
+
+1. `device_info(port=...)` — short summary (node num, firmware version, region, peer count)
+2. `list_nodes(port=...)` — full peer table (SNR, RSSI, pubkey presence, last_heard)
+3. `get_config(section="lora", port=...)` — LoRa settings for cross-device comparison
+
+Sequence these; don't parallelize on the same port.
+
+### Testing a firmware change
+
+1. Build locally: `pio run -e <env>`
+2. Flash the test device: `pio_flash(env=..., port=..., confirm=True)`
+3. Run the suite: `./mcp-server/run-tests.sh tests/<tier>` or `/test tests/<tier>`
+4. On failure, open `mcp-server/tests/report.html` → `Meshtastic debug` section for the firmware log tail + device state dump
+5. Iterate
+
+### Debugging a flaky test
+
+1. `/repro <test-node-id> [count]` — re-runs the test N times, diffs firmware logs between passes and failures
+2. If the first attempt always fails and the rest pass, that's a state-leak pattern → suggest `--force-bake` or a clean device state, don't chase the first failure
+3. If all N fail, this isn't a flake — it's a regression. Stop iterating and escalate to `/test` for full-suite context.

+
+## Recovery one-liners
+
+- **`userPrefs.jsonc` dirty after a test run?** Re-run `./mcp-server/run-tests.sh` once (pre-flight self-heals from the sidecar). If still dirty: `git checkout userPrefs.jsonc`.
+- **nRF52 not responding?** `mcp__meshtastic__touch_1200bps(port=...)` drops it into the DFU bootloader, then `pio_flash` re-installs.
+- **Device fully wedged (no DFU)?** `mcp__meshtastic__uhubctl_cycle(role="nrf52", confirm=True)` hard-power-cycles it via USB hub PPPS. Needs `uhubctl` installed (`brew install uhubctl` / `apt install uhubctl`); on Linux without udev rules, permission errors fail fast, so use `sudo uhubctl` yourself or configure udev access.
+- **Port busy?** `lsof <port>` to find the holder. Usually a stale `pio device monitor` or zombie `meshtastic_mcp` process. Kill it.
+- **Multiple MCP servers running?** `ps aux | grep meshtastic_mcp` — zombies hold ports. Kill all but the one your host spawned.
+- **macOS: `LIBUSB_ERROR_BUSY` on a CH341 LoRa adapter?** A third-party WCH `CH34xVCPDriver` is claiming interface 0. Find the bundle ID with `ioreg -p IOUSB -l -w 0 | grep -B2 -A30 0x5512`, then `sudo kmutil unload -b <bundleID>`. Apple's bundled CH34x kext targets the CH340 UART (PID 0x7523), not the SPI bridge — it's never the culprit.

+| ------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `MESHTASTIC_MCP_ENV_<ROLE>`          | Override PlatformIO env for a role (e.g. `MESHTASTIC_MCP_ENV_NRF52=rak4631-dap`). Default map: `nrf52→rak4631`, `esp32s3→heltec-v3`.                                                                       |
+| `MESHTASTIC_MCP_SEED`                | PSK seed for the session test profile. Defaults to `mcp-<user>-<host>`.                                                                                                                                    |
+| `MESHTASTIC_MCP_FLASH_LOG`           | File path to tee pio/esptool/nrfutil/picotool output. `run-tests.sh` sets this to `tests/flash.log` so the TUI can stream live flash progress.                                                             |
+| `MESHTASTIC_MCP_TCP_HOST`            | `host` or `host:port` of a `meshtasticd` daemon (e.g. the `native-macos` build). Surfaces it in `list_devices` as `tcp://host:port` so `connect()`-based tools target it transparently. Default port 4403. |
+| `MESHTASTIC_UHUBCTL_BIN`             | Absolute path to `uhubctl` binary. Default: PATH lookup.                                                                                                                                                   |
+| `MESHTASTIC_UHUBCTL_LOCATION_<ROLE>` | Pin a role to a specific uhubctl hub location (e.g. `1-1.3`). Wins over VID auto-detection — use when multiple devices share a VID.                                                                        |
+| `MESHTASTIC_UHUBCTL_PORT_<ROLE>`     | Pin a role to a specific hub port number. Required alongside `LOCATION_<ROLE>`.                                                                                                                            |
+| `MESHTASTIC_UI_CAMERA_BACKEND`       | Camera backend for UI tier + `capture_screen` tool: `opencv` / `ffmpeg` / `null` / `auto` (default).                                                                                                       |
+| `MESHTASTIC_UI_CAMERA_DEVICE`        | Generic camera device (index or path). Used by the UI tier when no per-role var is set.                                                                                                                    |
+| `MESHTASTIC_UI_CAMERA_DEVICE_<ROLE>` | Per-role camera pinning (e.g. `MESHTASTIC_UI_CAMERA_DEVICE_ESP32S3=0` for the OLED-bearing heltec-v3).                                                                                                     |
+| `MESHTASTIC_UI_OCR_BACKEND`          | OCR engine selection: `easyocr` / `pytesseract` / `null` / `auto` (default).                                                                                                                               |
+| `MESHTASTIC_UI_TUI_CAMERA`           | Set to `1` to mount the live camera-feed panel in `meshtastic-mcp-test-tui`.                                                                                                                               |

 ## Reporting a Vulnerability

 We support the private reporting of potential security vulnerabilities. Please go to the Security tab to file a report with a description of the potential vulnerability and reproduction scripts (preferred) or steps, and our developers will review.
+
+Before filing, please read the Security Model below. Behavior whose only precondition is local API access to a node, or possession of a channel's pre-shared key, is intended by design and is not considered a vulnerability.
+
+## Security Model
+
+Meshtastic is an off-grid mesh protocol that runs on constrained microcontrollers within a 256 byte LoRa packet limit. These constraints shape its security design and rule out the heavier schemes used by IP-based protocols. This section summarizes what the firmware protects, the assumptions it rests on, and its known limits. Fuller write-ups are in the documentation:
+
+- Encryption overview: https://meshtastic.org/docs/overview/encryption/
+- Technical reference: https://meshtastic.org/docs/development/reference/encryption-technical/
+- Known limitations and future work: https://meshtastic.org/docs/about/overview/encryption/limitations/
+
+### Cryptographic mechanisms
+
+- Channels are encrypted with a pre-shared key (PSK) using AES256-CTR. Channel traffic is encrypted but not authenticated, so anyone holding the PSK can read channel messages and can send messages as any node on that channel.
+- Direct messages and admin messages use public key cryptography (x25519 key exchange with AES-CCM), providing confidentiality, authentication, and integrity between nodes on 2.5.0 or newer that have exchanged keys.
+- Admin sessions use short-lived session IDs to limit replay of control messages.
+
+### Local trust boundary
+
+A client connected to a node over Bluetooth, USB serial, WiFi, or Ethernet has full local API access. From that connection it can read decrypted traffic, send messages as the node, change configuration (subject to managed mode), and read the node's private key for backup. This is intended behavior. The firmware trusts the local link the same way a phone or laptop trusts a directly attached device, and anything within reach of that connection (a shared LAN, a USB cable to an untrusted host, a paired phone) should be treated as part of the node itself.
+
+### Node identity (Trust On First Use)
+
+There is no central authority to sign node keys. The first public key a node hears for a given node number is the one it binds to that node number, a Trust On First Use (TOFU) model that is a hard requirement of a decentralized mesh. Clients and firmware reduce the impact of this by keeping favorited nodes from rolling out of the node database and by flagging public-key changes in the client UI.
+
+Firmware 2.8.X adds XEdDSA packet signing to further secure node identity claims and the authenticity of subsequent messages. It reuses each node's existing x25519 key pair to produce signatures, so a receiver can verify that a packet came from the holder of the bound key. Once a node has been seen signing, unsigned packets claiming that identity can be rejected.
+
+### Known limitations
+
+- No perfect forward secrecy. Traffic captured today can be decrypted later if a key is compromised, for example through a lost node or a mishandled channel key.
+- Channel messages are not authenticated, as noted above. Although as of 2.8, channel messages will be xedDSA signed as a means of verification that is non-breaking.
+- Setting WiFi credentials, or performing any other local administration, on an ESP32 over an untrusted network exposes that traffic, including the credentials, to the network. Provision and administer nodes over a trusted channel instead: Bluetooth, USB serial, or remote admin over the mesh. There is no current roadmap item to secure local administration over untrusted WiFi, though it may be addressed in a future release.

+# meshtasticd configuration files
+
+This directory contains YAML configuration files for meshtasticd. Each file describes a specific hardware configuration, including the LoRa module and pin assignments. These configurations are used by meshtasticd to correctly interface with the hardware.
+
+## Metadata structure
+
+Each configuration file includes a `Meta` section that provides information about the configuration.
+This configuration is consumed by configuration-selection tools.
+
+```yaml
+Meta:
+  name: MeshAdv-Pi E22-900M30S # A unique identifier for this configuration.
+  support: community # community, official, or deprecated; determined by Meshtastic Leads.
+  compatible: # A list of compatible products or platforms.
+    - raspberry-pi
+```
+`name`: A unique identifier for the configuration, typically reflecting the hardware it supports.
+
+`support`: Indicates the level of support for this configuration. It can be one of the following:
+
+- `community`: Supported by the Meshtastic community. Meshtastic Members may not possess, or have not tested this configuration.
+- `official`: Fully supported by Meshtastic. Meshtastic Members have tested and verified this configuration.
+- `deprecated`: No longer recommended for deployment by Meshtastic.
+
+`compatible`: A list of compatible products or platforms that can use this configuration.
+This will vary depending on the intended use case / platform.
+Multiple compatible entries can be included. E.g. Armbian `BOARD` value or OpenWrt `TARGET` value.
+These tags can be consumed by different configuration-selection tools, filtering based upon their platform/etc.
