+
+# `/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**:
+

+   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.

-## NodeDB Layout (v25)
-
-`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, `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.
-
-### Gradient sync (opt-in via special nonces)
-
-`client_capabilities` is **not** a thing in this branch. Phone clients opt into the new sync flow by sending one of two values in the `ToRadio.want_config_id`:
-
-- `SPECIAL_NONCE_GRADIENT_SYNC` (69422) — full config + thin NodeInfo + replay phases.
-- `SPECIAL_NONCE_GRADIENT_ONLY_NODES` (69423) — skip config segments, NodeInfo + replay only.
-
-`PhoneAPI::clientWantsGradientSync()` is the single switch. When true, `STATE_SEND_OTHER_NODEINFOS` is followed by:
-
-```text
-STATE_REPLAY_POSITIONS → STATE_REPLAY_TELEMETRY → STATE_REPLAY_ENVIRONMENT → STATE_REPLAY_STATUS
-```
-
-Each replay phase walks the corresponding satellite map and emits synthetic `MeshPacket`s on the matching portnum (`POSITION_APP`, `TELEMETRY_APP` for both device + environment variants, `STATUS_MESSAGE_APP`). Legacy clients (no special nonce) get the bundled-NodeInfo path with position/device_metrics joined back in by `ConvertToNodeInfo(lite, pos*, dm*)` — wire bytes are byte-identical to pre-v25 for them.
-
-`ConvertToNodeInfoThin(lite)` is the gradient-sync emitter (no position/telemetry).
-
-### 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.

 - **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.
 - **`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.

+
+Usage:
+    DD_API_KEY=... ./scripts/mtlog_to_datadog.py --tail
+    ./scripts/mtlog_to_datadog.py --once          # catch up + exit
+    ./scripts/mtlog_to_datadog.py --since 3600   # backfill last hour from start
+
+Default `DD_SITE` is `us5.datadoghq.com` — the team's Datadog instance.
+Override via `DD_SITE=...` env var or `--site` flag for one-offs.
+
+The forwarder is a separate process by design — a Datadog outage or
+auth failure must not backpressure the recorder. We exit non-zero on
+fatal config errors (missing API key) and keep retrying on transient
+network/HTTP errors.

+exceeds the requested end. The recorder writes monotonically, so a
+forward scan is cheap; we don't need an index.
+
+All time arguments accept:
+  - epoch seconds (int/float)
+  - relative strings: "-15m", "-2h", "-3d", "now"
+  - ISO-ish absolute strings: "2026-05-07T14:30:00" (naive timestamps are
+    treated as UTC)
+
+Tools that return data ALWAYS cap their output (max_lines / max_points
+/ max), and report whether more matched than was returned.

+"""Best-effort parsers for log lines and telemetry packets.
+
+Two flavors of log line cross our pubsub subscription:
+  1. Text-mode path (debug_log_api disabled): the meshtastic Python lib
+     accumulates bytes between protobuf frames and emits the full
+     firmware-formatted line, e.g.
+         "INFO  | 12:34:56 12345 [Main] Booting"
+     — level, HH:MM:SS, uptime seconds, thread bracket, then message.
+  2. LogRecord protobuf path (debug_log_api enabled): the lib calls
+     `_handleLogLine(record.message)` with ONLY the message body. The
+     level/source/time fields on the LogRecord are dropped before
+     pubsub fan-out. We get e.g. just "Booting".
+
+Both arrive on `meshtastic.log.line`. The parser tries to recover a
+level + thread when the prefix is present and falls back to level=None
+otherwise. Consumers who want level filtering on protobuf-mode hosts
+should grep the raw `line` field instead.
+
+Telemetry: `meshtastic.receive.telemetry` packets carry one of several
+metric variants in `packet["decoded"]["telemetry"]`. We flatten the
+chosen variant into a {field: value} dict so callers don't have to
+know the protobuf shape.

+"""Append-only JSONL writer with size-capped rotation.

+A `_RotatingJsonl` owns one live `.jsonl` file. Writes are line-delimited
+JSON objects (one row per call). When the live file exceeds `max_bytes`,
+it is closed, gzipped to `<name>.YYYYMMDD-HHMMSS-uuuuuu-NNNNN.jsonl.gz`,
+and the live file resets to empty. Old archives past `keep_archives` are
+unlinked oldest-first.
+
+Size check is amortized — `os.fstat` runs every `check_every` writes,
+not per-write, so the hot path stays at one `fh.write` + one `fh.flush`.
+
+Threading: every public method acquires `self._lock`. The recorder runs
+several pubsub handlers on whatever thread the meshtastic library
+dispatches from (varies by interface), and queries from MCP tool calls
+arrive on the FastMCP request thread, so this lock is not optional.
