`since` cursor kept per container in `state` (a container's first interval
seeds from a short tail). Demuxes the multiplexed stream, parses each line's

a truncation; the deferred lines come next interval). Folded into the sample as

- **`metadata` is sent on every POST**, not just on change. Server-side diff detects actual changes and only writes on change. Cost per POST is one dict — negligible. Benefit: server can cleanly detect agent restarts.
- **Raw bytes, not percentages, for memory and storage.** Percentages are derived server-side. Changing the "what counts as used" math doesn't require re-releasing the agent.
- **CPU is the one exception** — reported as a percentage because it's inherently a derivative (delta over time), not a snapshot. The agent must sample twice to compute it.
- **Container logs (m79) ride in the same push** as `docker_logs`: a list of `{container, stream, ts, line}` records — incremental since the previous interval. This pushes the *same direction* as metrics, so batched log history needs no inbound channel (only sub-second live-follow would). The server ingests them into `docker_logs`, enforces the global toggle + exclude list on ingest, and bounds storage with a per-container size+age ring. `docker_logs` is omitted when there's nothing new.
