A non-empty value sets/replaces the run's `run_name`; an empty string clears it, restoring the unnamed (run_id-only) state. Names are trimmed and capped at 120 characters. The name is persisted on the execution record and returned by execution GET/LIST responses (`run_name`, omitted entirely while unnamed), so run selectors and execution-history views can show 'July tuning baseline' instead of `run_a8e2709532...`. Sibling of PATCH `.../executions/{run_id}/labels`: each display field gets its own strict single-purpose PATCH rather than a general execution PATCH, because execution results themselves are immutable. Example body: `{"run_name": "July tuning baseline"}` (or `{"run_name": ""}` to clear). ## OpenAPI ````yaml patch /v1/clusters/{cluster_id}/executions/{run_id}/name openapi: 3.1.0 info: title: Mixpeek API description: >- This is the Mixpeek API, providing access to various endpoints for data processing and retrieval. termsOfService: https://mixpeek.com/terms contact: name: Mixpeek Support url: https://mixpeek.com/contact email: info@mixpeek.com version: '0.82' servers: - url: https://api.mixpeek.com description: Production security: - BearerAuth: [] paths: /v1/clusters/{cluster_id}/executions/{run_id}/name: patch: tags: - Cluster Executions summary: Name an Execution Run description: |- Set (or clear) a human-friendly name on a single execution run — no re-run required.
