+
+# `/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

+   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.

+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.

+"""Forward selected recorder JSONL streams to Datadog.
+
+Reads `.mtlog/logs.jsonl` and `.mtlog/telemetry.jsonl`, ships logs to the
+Logs Intake API and telemetry numerics to the Metrics v2 series API.
+Resumes from `.mtlog/.dd-cursor.json` so a daemon restart doesn't
+duplicate rows already shipped from the current live files.
+
+This forwarder does not currently backfill rotated `.jsonl.gz` archives.
+If the recorder rotates before this process drains the live file, or the
+forwarder is down across a rotation, those older rows are skipped.
+
+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.

+     firmware-formatted line, e.g.
+         "INFO  | 12:34:56 12345 [Main] Booting"

+otherwise. Consumers who want level filtering on protobuf-mode hosts
+should grep the raw `line` field instead.

+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.

-//   name             - human-readable label shown in the theme picker.

-//                      uiconfig.screen_rgb_color and restored at boot.
-//                      This is a CONTRACT with saved configs on disk - once
-//                      assigned, never reuse or renumber, even if the theme is
-//                      deleted or the kThemes[] array is reordered.
-//   visible          - controls whether a theme appears in the picker menu.
-//                      Hidden themes can still be restored and applied if their
-//                      uniqueIdentifier is persisted.
-//
-// Display order in the menu is controlled by kThemes[] array order among
-// themes where visible == true, NOT by any numeric value above.
-//
-// To add a new theme:
-//   1. Add a unique constant in ThemeID below (next unused value).
-//   2. Add a kThemes[] entry at the desired menu position, with a unique
-//      uniqueIdentifier that has never been used by any prior theme.
-//   3. Set visible=true if it should appear in the picker.
-//
-// To retire a theme without breaking saved configs:
-//   - Preferred: keep the entry and set visible=false so existing saved
-//     uniqueIdentifier values still resolve to the same theme.
-//   - If you remove the entry, resolveThemeIndex() falls back to DefaultDark
