-- Channel-2 auto-responder (`src/commands`): event-driven — `CommandService.onRx()` is called by `MeshService` for every decoded rx text (right after the notify gate) and dispatches exact, case-sensitive `#command` matches on `COMMAND_CHANNEL` (env, default 2) through a single-registration-point registry (handlers registered in the constructor via `register(name, fn)`; handler gets `{ text, from?, id? }`, returns a reply string — or an array of lines, sent as one message per line through the same routing — or void = no reply). First command: `#ping` → replies `#pong!`. Replies go through `MeshService.respond(id, reply)`: auto-routed (rx → DM back to the original sender unless the original was a broadcast; tx → its destination), riding the original record's channel with `replyId = id` so the recipient app renders it as a threaded quote — `COMMAND_CHANNEL` is only the trigger/listen gate. Only when the trigger has no packet id does it fall back to legacy sendText routing on `COMMAND_CHANNEL`. A failing handler/respond only logs a warn.

Methods: `listModels()` → `data[].id`; `chat(messages, { maxTokens?, temperature? })` → `choices[0].message.content` (non-2xx throws with status + body snippet); `summarize(text)` = chat() with system prompt "Summarize the following text concisely." Env: `LLM_API_BASE`, `LLM_MODEL` (default `qwen3.8-27b`), `LLM_TIMEOUT_MS` (default 180000, via `AbortSignal.timeout`).

 # Changelog
 
+## v0.21.5 — 2026-09-26 10:26
+
+- Multi-line command replies are now spaced apart: `CommandService.onRx` waits `MESH_MULTI_SEND_DELAY_MS` (new env, default **5000** = 5 s, read at construction) between consecutive lines of an array reply — no delay before the first line. Production incident: `#rss get lublin` sent its items back-to-back within the same second and 3 of 4 were dropped in RF (the owner saw only the last one); each packet now gets time to land.
+- Tests: 172 → 173 — a 3-line reply with an overridden short delay asserts all lines are sent, the first goes out immediately (no pre-delay), and each subsequent line lands ≥ the configured gap after the previous one; existing specs pin `MESH_MULTI_SEND_DELAY_MS=0` in `beforeEach` so they stay fast.
+
 ## v0.21.4 — 2026-09-26 09:51
 
 - `LLM_TIMEOUT_MS` default raised from 60000 (60 s) to **180000** (3 min): production incident — `#rss get lublin` at 9:41 AM failed with "The operation was aborted due to timeout" because the local OpenAI-compatible server (qwen3.8-27b, uncontrollable reasoning tokens) was slow/busy on that call; the same endpoint answers a trivial prompt in ~1 s when idle, so this is latency variance, not a dead endpoint. Still env-overridable (`LLM_TIMEOUT_MS`), only the fallback changed.
