Log payloads must not carry artifact chunks, host paths, raw credentials, direct sockets, or unbounded inline data.
+Current Run output uses `POST /api/v1/run/logs/relay`. The route validates the active Run session and stream binding, updates only bounded stream metadata such as latest sequence/session identity, and immediately fans entries out to live subscribers. It does not persist log bodies, does not create a resend backlog, does not require platform sequence acknowledgements for progress, and does not block lifecycle/control/job work on delivery success.
 
-Run-assigned Platform jobs use `job.<jobId>.<streamKey>` log stream IDs. Autonomous lifecycle bootstrap is Run-owned machine execution rather than a Platform job, so its durable process logs use `run.<runEndpointId>.<serverInstanceId>.<streamKey>`. Platform may auto-create those streams only after validating the active Run session and the server-to-Run binding. For retry compatibility, legacy spooled `job.autonomous-*.<streamKey>` batches are accepted as Run-owned autonomous streams without creating or completing a Platform job.
+Server terminal streaming uses `GET /api/v1/server-instances/{id}/logs/events`; SCUM companion streaming uses `POST /api/v1/game-client-bridge/companion/logs/events` with the component session token in the typed JSON body. Both emit only the current supervised process session and do not replay retained platform log bodies. Platform is the live relay only. The game plugin/companion owns game-log storage, semantic analysis, and console-page fan-out behavior.
 
-Log ingest is durable and independently retried. Artifact/file transfer backlog must not prevent log batch acknowledgement, duplicate acknowledgement, cursor state updates, or spool cleanup.
+`POST /api/v1/run/logs/batches` and `POST /api/v1/log-streams/query` remain compatibility/internal maintenance contracts for older durable-ingest flows.

Log payloads must not carry artifact chunks, host paths, raw credentials, direct sockets, or unbounded inline data.
 
-The platform stores log stream metadata through `repo.Store` and stores log bodies through the configured `LogBodyStore`. The default `file` backend persists platform metadata to `PLATFORM_METADATA_PATH` and appends log entries to segmented JSONL files under `PLATFORM_LOG_DIR`; the `memory` backend is only for tests and disposable local development. MySQL/Postgres are appropriate for platform metadata, stream state, retention policy, indexes, and operational records, but should not be the primary row-per-log-line store for hundreds or thousands of servers. Production log bodies should move behind the same boundary to append/query backends such as ClickHouse, Loki, OpenSearch/Elasticsearch, or object-storage segments with compact indexes.
+The platform stores log stream metadata through `repo.Store`. Game-specific durable log bodies and derived semantic records belong to the owning game plugin; for SCUM that storage uses plugin-owned SQL tables and stores raw world coordinates without map projection or coordinate conversion.

 ## Server File Manager Transfer

 Browser uploads are first staged as server-instance artifacts. Platform then queues a `files.write` job whose `inputRef` is `artifact://<id>` and whose execution input names the dedicated `run-file-transfer` channel. Run pulls those bytes through `POST /api/v1/run/files/input-chunk` while proving the active endpoint session plus job attempt and lease. The chunk route is fenced to the active file-write job, validates artifact ownership/checksum, and returns bounded byte ranges only.
