Append one or more rows to a mount-scoped table — on behalf of the operator (or an agent acting in the operator’s stead). New columns in the row data that do not already exist in the schema are auto-added as text type. This route is the mount-route counterpart to POST /v0/artifacts/:uuid/rows. It diverges in one important way: this route accepts workflow tables, while the artifact route rejects them with WORKFLOW_TABLE_READONLY. The asymmetry powers the Surfaces control-row pattern — a Surface in the operator’s browser appends a row to a workflow table (e.g. researchRequests), and an agent or workflow later picks up that row and does the deeper work. Auth: API key (agent) or user session (operator). Caller must own the mount or be a current team member. Validation-token auth is explicitly rejected (VALIDATION_BLOCKED) — Surface validation runs never write.

Errors

StatusCodeCause
400INVALID_BODYrows is missing, empty, or not an array
403MOUNT_ACCESS_DENIEDCaller is neither the mount owner nor a current team member
403VALIDATION_BLOCKEDAuth context is a Surface validation token (mutating SDK calls are blocked during validation)
404MOUNT_NOT_FOUNDNo mount with that id
404TABLE_NOT_MOUNTEDSlug does not match any materialized table on the mount
