Purpose: records an interpretation/decision while keeping facts in RailWarden. Schema: schemas/contracts/supervisor-action.schema.json. Required: schema_version, task_id, action, rationale; tool call and result are optional. Valid/invalid examples: examples.json#/supervisor-action.
Hermes produces actions such as retry, handoff, model swap, or ask-user; RailWarden executes only allowed mechanics and records the result. Versioning/migration: provisional. A generic supervisor contract is not yet promised. Maturity: experimental.
