Wzorzec mechaniczny: sekcje deploy/verify/install/testy wycinane do
kb/runbooks/<serwis>-*.md, reszta zostaje dokumentem type: service.
Wzajemne `links` w obie strony. Tresc sekcji nietknieta — przenoszone
doslownie, dodany wylacznie naglowek H1 nowego runbooka.
kb-query, paperless-worker, planner-agent, ha-diag-agent, ollama-piha,
narty27, home-assistant, ha-mcp, job-gmail-header-backfill, job-mail-body-ingest.
Weryfikacja: dla kazdego pliku multizbior niepustych linii
(main + runbook) == oryginal z HEAD. Zero zgubionych, zero dodanych.
Recon szacowal 13 splitow service+runbook; faktycznie 2-typowych jest 10,
pozostale 5 (paperless, nextcloud, gokapi, fleet-prometheus, deploy-runner)
sa 3-typowe i ida osobno jako splity wielotypowe.

Own minimal MCP server exposing the live state of the HA instances in
services/home-assistant/instances.yaml to Claude Code over stdio — the
phase-2 "MCP read-only" gate in services/home-assistant/DESIGN.md.
Operator decision 2026-07-30: build our own rather than adopt hass-mcp,
so the tools reuse scripts/ha/lib/{ha_api,ha_ws}.py (one token-handling
story for the whole HA toolchain) and can answer from the repo and from
instances.yaml, which a generic server cannot.
Seven tools, all read-only, default instance `ken`: list_entities,
get_state, get_areas, find_entities_by_description, read_automation,
list_automations, instance_status.
Read-only by construction, not by policy: REST goes through ha_api.Client
(get/get_raw_text only — no POST method exists), WebSocket commands are
checked against a three-entry *_list allowlist before being sent, and
read_automation reads services/home-assistant/config/<instance>/ rather
than /api/config. Tests assert all three, including a grep guard that
fails if requests.post/call_service ever appears in the package. The
write path stays repo + scripts/ha/deploy.sh.
Details that follow from how this instance actually behaves:
- unavailable is never silent — every entity view carries unavailable +
unavailable_since, every list a count. The 2026-07-23 audit traced ~15
silently dead automations to conditions sitting on dead sensors.
- chelsty-ha (status: offline in instances.yaml) is answered from the
file, never dialed — no 5s timeout for a known-offline LTE site.
- areas come from the WS registries (entity area_id > device area_id) with
a storage-export fallback; area_source/area_note say which was used and
what the offline export cannot resolve.
- PL->EN fuzzy matching, since the house is Polish and the entity_ids are
transliterated English: "czujnik temperatury salon" ->
sensor.thsalon_temperature, each hit explaining why it matched.
- 5s timeouts and errors returned as {"error": ...} inside a normal tool
result — a missing token or an unreachable instance never crashes the
server or hangs the agent.
Registered for Claude Code in the repo-root .mcp.json (new file) as `ha`,
via services/ha-mcp/run.sh (prefers the venv, falls back to system
python3). The mcp SDK lives in services/ha-mcp/.venv — rationale for venv
over --break-system-packages is in the README.
Tests: 42 offline (no network, no HA, no token) + a live read-only smoke
against ken — HA 2026.7.2, 1647 entities, 377 unavailable, 115
automations, 13 areas.
