`GET /api/tasks/{id}/runner-line` — the member-safe runner match line for a task (#708 M4). Composes the pin-aware dispatch state; returns `NotFound` for a task outside the caller's active workspace.

Task id

Slim runner match line (count + group boolean; no fleet identity)

Media typeapplication/json

The member-safe runner match line (#708 M4). Deliberately SLIM: the count of eligible runners, whether a worker-group constraint applies, and the derived state word. No runner id/name/host/token ever appears here — this is the exact wire a plain member receives.

object
in_group
required

True when a worker-group required-label set applies to this project/task (RUNG 1b), so the FE can render “… in group ”. The label VALUES are not exposed here — only that a group constraint is in force.

boolean
match_count
required

How many registered runners are eligible to run this work right now (online, undrained, fresh heartbeat, grant admits the workspace + labels, advertises the required labels). 0 in the local/waiting states.

integer format: int64
state
required

matched | local | waiting — the composed row’s headline state.

The canonical JSON body of every error response — the single source of truth the frontend binds to. Every AppError serializes as this exact shape, and the generated OpenAPI component ApiErrorBody (with its ErrorCode enum) is what the frontend error schema is generated from, so there is no hand-written error schema on either end.
