-"""Log channel storage for `InMemorySaver` (transcript log prototype).

-The reference implementation of the log storage design: entries stored once,
-keyed in path order; one step row per committing channel version; segments
-for linear runs, with parent pointers between them. Reads are range reads
-over a segment chain, and lifecycle is reachability from the checkpoints that
-remain.
-
-Rows, per `(thread_id, checkpoint_ns, channel)`:
-
- segment: `seg -> (parent_seg | None, fork_pos)`
- step: `version -> StepRow(seg, start, count, batch)`, unique on `(seg, start)`
- entry: `seg -> {(start, batch, task_path, task_id, idx, j): json_text}`
-
-`batch` names the execution that wrote a step's entries: the checkpoint the
-step started from for entries that came through `put_writes`, the committing
-checkpoint for entries a `LogStep` carried inline.

+### `langgraph deploy metrics`
+
+Fetch deployment monitoring time series as JSON through the LangSmith control plane.
+Use `langgraph deploy list` to find the deployment ID. Authentication uses the same
+API key and workspace configuration as the other deployment commands.
+
+```bash
+langgraph deploy metrics DEPLOYMENT_ID \
+  --start-time 2026-10-28T00:00:00Z \
+  --end-time 2026-10-28T01:00:00Z \
+  --metrics cpu_usage,memory_usage,worker_count
+```
+
+Omit `--metrics` to fetch all available metrics. Time bounds default to the start of
+the current hour through now, and the backend picks the resolution from the time
+range. Output contains
+charts and their time-series data, not traces. This command never prompts; for an
+organization-scoped key, set `LANGSMITH_TENANT_ID` to the workspace ID.
+
+### `langgraph deploy scale`
+
+Change a deployment's compute tier, dedicated Postgres tier, or both. Omitted
+settings remain unchanged. The backend enforces deployment permissions, supported
+tiers, and platform restrictions.
+
+```bash
+langgraph deploy scale DEPLOYMENT_ID \
+  --compute-tier DEDICATED_M --database-tier DEDICATED_L
+```
+
+Compute tiers are `SERVERLESS_S`, `SERVERLESS_M`, `SERVERLESS_L`, `DEDICATED_S`,
+`DEDICATED_M`, and `DEDICATED_L`. Database tiers are available only for dedicated
+deployments: `DEDICATED_S`, `DEDICATED_M`, and `DEDICATED_L`. Availability depends
+on the deployment's platform and enabled features.
+
+Scaling prompts for confirmation because it creates a revision, may interrupt
+service, and may change billing. Pass `--yes` to confirm without prompting, with
+credentials and workspace configured for non-interactive use. The command reports
+that scaling was requested; it does not wait for the revision to become healthy.
+Arbitrary worker replica overrides are not supported by this command.
+
 ## Configuration

 The CLI uses a `langgraph.json` configuration file with these key settings:

-these entries". Its entries are not stored in checkpoints. A checkpoint's
-value for the channel is a marker (`LogStep`) for the step that produced its
-version, and the entries live in the saver's log storage, read with
-`BaseCheckpointSaver.read_log`.
-
-Two channel types share that storage:
-
- `Log` holds JSON values. Anything that isn't JSON is rejected.
- `MessagesLog` holds LangChain messages, stored as canonical JSON. Edit ops
-  (`RemoveMessage`, `Overwrite`, re-adding an existing id) are rejected; a
-  graph that needs a different model context builds it as a projection.
-
-A thread whose field held a plain list before it became a log channel (for
-example `Annotated[list, add_messages]` changed to `MessagesLog()`) keeps
-working: the stored list becomes the log's first entries, the "seed". The
-seed is committed with the first checkpoint saved after the change, and
-checkpoints from before the change still read as the list they stored.

 # Changelog

-## 0.4.12

-### Removed
-
- **`PrioritySettings.fairness_weight`** — removed. The server stores only
-  `priority` and `fairness_group` on the thread; it ignores a
-  `fairness_weight` and logs a warning. Remove it from your callback.
-
-### Changed
-
- **`PrioritySettings.priority`** — now says -5 runs first and 5 runs last,
-  matching how the server orders runs. 0.4.9 to 0.4.11 said the reverse, and
-  their example gave premium users 3, which runs them after everyone at the
-  default 0. Check any callback written from those docs.
