Two root causes for stale "active" incidents on the dashboard:
1. TypeError bug in _prune_stale_world: last_occurrence / resolved_at
can be an ISO-8601 string (stability-agent via events.py) or a Unix
int (node-agent). The previous session's auto-resolve did plain
`time.time() - last_occ` which raises TypeError for strings,
silently preventing _save_world() from being called and leaving
incidents perpetually "active" on disk.
Fix: add _parse_ts(ts) -> float that handles int, float, and
ISO-8601 strings uniformly. All timestamp arithmetic now goes through
it; returns 0.0 on None / garbage to keep comparisons safe.
2. Orphaned active incidents: _resolve_incident clears service["incident_id"]
and marks the incident "resolved" in memory, but if incidents.json was
truncated mid-write (pre-atomic-write era), the observer loaded it at
next startup with status="active" and no service entry pointing to it.
No code ever touched these orphans again.
Fix: _prune_stale_world now runs two cleanup passes each cycle:
- Case 1 (healthy-linked): service.status=="healthy" AND incident_id
still set → resolve immediately (service cannot have active incident)
- Case 2 (orphaned): active incident with no service link AND
last_occurrence > 5 min ago → resolve (5-min guard for creation race)
Both cases are wrapped in try/except so a bug here never crashes the
observer loop or blocks _save_world.
Also fixes the 7-day stale-incident prune to use _parse_ts so
ISO-string resolved_at values are handled correctly.
3. Operator UI: current_incidents() now filters to status=="active" only.
Resolved incidents were previously included in the /incidents endpoint,
making the dashboard show a wall of historical records as if active.
Nocturnal job investigation: _cleanup_control_plane_fs in node-agent runs
every 60s on VPS (not midnight-specific); it reads observer_checkpoint.json
(now written atomically) and deletes old event files. No non-atomic writes
found. Midnight clustering was likely external (logrotate / OS flush);
the supervisor's resilient loader already handles such transient issues.

All JSON state writes (services.json, nodes.json, incidents.json,
deployments.json, runtime-summary.json, observer_checkpoint.json) now use
_atomic_write_json: write to a .tmp sibling, fsync, then os.replace.
This eliminates the truncated-write window that caused supervisors
reading mid-write files to see empty/partial JSON.
Also adds auto-resolution of phantom active incidents: if a service
reports status=healthy and its incident's last_occurrence is >30 min old,
the incident is resolved in _prune_stale_world. This clears false active
incidents accumulated from previous race-condition reads.

node-agent: use com.docker.compose.service label as canonical name
- Add _canonical_container_name() method: prefers compose label,
falls back to hash-prefix-stripped c.name
- Replace bare c.name usage in check_containers()
- Skip 'created'-state containers (Docker stale-state artifacts)
observer: prune hash-prefixed ghost keys in _prune_stale_world()
- Each reconcile cycle removes service keys matching <node>/<12hex>_<name>
- Acts as safety net for entries already in services.json + future slippage
control-plane/docker-compose.yml already has explicit container_name on
all four services — no change needed there.

service_healthy is a positive health confirmation — if the service had
an active incident (e.g. from earlier service_unhealthy events), that
incident should be resolved when the service is confirmed healthy.
Previously only service_recovered resolved incidents; service_healthy
set status=healthy but left incidents open, keeping status='degraded'.

- node_agent: emit service_healthy for all running managed containers so
observer populates services.json (previously empty → supervisor flooded
action queue with missing_service redeploys for healthy services)
- node_agent: VPS-only _check_control_plane_health() probes the HTTP
endpoint to emit service_healthy/unhealthy for the 'control-plane' logical
service (multi-container stack, container names don't match service name)
- node_agent: fix _cleanup_control_plane_fs() to read new node_checkpoints
format from observer checkpoint (was reading old last_processed_file key,
always found nothing, never cleaned up old events)
- observer: handle service_healthy event type → sets service status healthy
without resolving incidents (unlike service_recovered which also resolves)

The old mechanism tracked a single 'last_processed_file' and used sorted
filename order to find new events. Remote nodes ship events into
subdirectories (events/piha/, events/chelsty-infra/) that sort
alphabetically BEFORE the VPS directory (events/vps/). Once the
checkpoint pointed to a vps/ file, all piha/ and chelsty-infra/ events
were silently skipped forever.
New mechanism:
- node_checkpoints: {node_dir: last_processed_path}
- Each node directory has its own independent cursor
- New events = files whose path > that node's checkpoint
- Backward-compatible: old 'last_processed_file' is migrated by extracting
the node dir from the path on first load

Root cause of stale data:
- node_agent.py falls back to socket.gethostname() when NODE_NAME is unset.
Inside a Docker container this returns the 12-char container ID (e.g.
'be17cb6eb0f6'), not the host name. Observer ingested those events and
created ghost entries in world/nodes.json that never expired.
observer.py:
- _prune_stale_world(): removes node/service/incident entries for nodes absent
from topology inventory; called on every run_once() cycle (both new-events
and idle paths). Resolved incidents older than 7 days are also aged out.
- _save_world(): now writes node_count and service_count to runtime-summary.json
so the Dashboard's System Overview cards show real numbers instead of undefined.
operator_ui.py:
- current_nodes/services/deployments/incidents(): the observer stores world state
as keyed dicts; the frontend calls .map() which requires an array. All four
functions now convert the dict to a properly-shaped list. Each item has the
fields the Nodes, Services, Topology, Deployments, and Correlation views expect
(hostname, health, capabilities, desired_state, dependencies, etc.).
- current_incidents(): synthesises a human-readable 'message' field from node +
service + trigger_type (observer does not store one; dashboard showed undefined).
- current_events(): adds a 24 h time filter (EVENTS_MAX_AGE_HOURS env var,
default 24). Without this, every event file ever written was returned,
including events from ghost-node deploys.

- observer: store trigger_type on incidents for supervisor routing
- supervisor: route containers_not_running/mqtt_unreachable to container_restart instead of redeploy
- supervisor: fix node alias normalization via NODE_ALIAS_MAP
- supervisor: fix pending action dedup (scan by content not filename)
- executor: implement container_restart via SSH docker restart with retry
- control-plane override: configure NODE_ALIAS_MAP for production
