        Returns durable run summaries from the backing store, including runs
        persisted before the current server boot. Supports per-status filtering
        and sorting for both list and kanban renderings. Archived runs are
        hidden by default; pass `include_archived=true` (or `status=archived`)
        to include them. Runs in the `removing` bucket are hidden unless
        explicitly requested via `status=removing`.

      description: |
        Returns the set of file changes produced by a run as a list of before/after diffs.

        While the run's sandbox is reachable, diffs are resolved live against the sandbox working tree at the current HEAD. Degraded responses keep the same `data: FileDiff[]` shape. File contents are null on every entry; non-sensitive non-flagged entries include `unified_patch`, while sensitive / binary / symlink / submodule / truncated entries render through the same placeholder flags used by the live path.

        Responses are bounded by per-file (256 KiB / 20k lines), per-run aggregate (5 MiB), and per-request (200 files) caps. Files exceeding a cap are returned with `truncated: true` and empty `contents`. Sensitive paths (credentials, keys) are elided with `sensitive: true` and empty `contents`.

      description: |
        Uploads one or more artifacts for a stage. Intended for trusted internal callers.

        The server accepts both:

        - strict manifest-first `multipart/form-data` uploads documented by `ArtifactBatchUploadManifest`

        The generated Rust client currently exposes the octet-stream variant because the OpenAPI
        code generator in this repo does not support multiple request media types on one operation.

        Drives a single turn of the playground chat that builds a workflow

        the full current draft, and the response streams text deltas plus a
        single `write_workflow_file` tool call carrying the full new contents
        of `workflow.fabro` for the client to parse, diff against its local
        draft, and animate into the canvas.

        Responses are always SSE. Frames use `event: stream_event` with a
        JSON-serialized StreamEvent payload — see /api/v1/completions for the
        StreamEvent shape. The tool call arrives on a `tool_call_end` event
        with the tool name and parsed JSON arguments.

        Replaces `PaginationMeta` on the files endpoint — the naturally-bounded list does not use cursor pagination but exposes caps and a degraded-response path instead.

          description: Number of files dropped because the aggregate 5 MiB budget was exhausted. Zero or absent when no files were dropped for budget reasons.

          type: boolean

Entries flagged `sensitive` / `binary` / `symlink` / `submodule` / `truncated` render via the same placeholders used in the live path (the flags drive rendering; contents are null in degraded mode regardless). The data shape is otherwise identical to the live path.

        A single resolved prepare step. The runnable part preserves the
        script-vs-argv distinction via the `type` discriminator: a `script`
        is a raw shell snippet kept verbatim, while a `command` is an argv
        whose elements are shell-quoted and joined at the run boundary (after
        `{{ env.* }}` resolution) so an interpolated value cannot inject shell
        syntax. Optional per-step `env` is shared by both shapes.
