Wire the box-side build->dispatch->verify run identity so the verifier gate
can bind to the CI run the dispatcher triggered:
- task_model: add run_id / ci_correlation_tag / dispatched_at to TaskRecord +
PipelineState (+ dict round-trip).
- dispatcher: RunLocator seam + DispatchResult; dispatch_apply_verify stamps a
dispatched-at watermark, fires, then resolves the run via the workflow
run-name (gh run list; the per-task_id concurrency group makes it
unambiguous). Fails closed to run_id=None.
- dispatch_invoker: persist run_id/dispatched_at/ci_correlation_tag into state.
- workflow: additive run-name surfacing inputs.task_id as the correlation key
(flagged for the C1 /sh-security-review + GPT-4.1 cross-review re-run).
- docs: P3-PHASE0-DESIGN.md records the async-resume design decision.
Part of Phase 0 (feat/agent-team-p3-box-integration). No behavior change on the
default path: P3 wiring is still opt-in/inert.
