Platform service logs (internal)

Engineering one-pager for HEAT platform log surfaces and the Cluster Manager collector.

Surfaces

Service	Mechanism	Endpoint
core-api	HEAT.Common `HEATLogger` in-memory ledger	`GET /_logs/coreapi`, `GET /_logs/coreapi/pretty`
heat-auth	Same	`GET /_logs/auth`, `GET /_logs/auth/pretty`
heat-v2-api	Serilog console only	No ledger; Cluster Manager uses `kubectl logs deployment/heat-v2-api`

Ledgers default to 1000 entries per pod (HEATLogger.cs). Entries go to ledger + stdout; auditor ingest is explicit (HeatAuditorClient.cs), not automatic.

Cluster Manager

Collector: serviceLogCollector.ts
Routes: GET /api/environment/service-logs, GET /api/environment/service-logs/:serviceId (admin)
Wired in app.ts via startServiceLogCollector()
Advisories read getServiceLogSnapshots() from AdvisoryContext
