samples mode: call-workflow replay drops the workflow name #55176
Description
Summary
In samples mode, the dynamically generated call-workflow MCP tool now registers and replays, but the emitted canonical call_workflow message omits its workflow identity. The apply job rejects it with Workflow name is empty.
Follow-up to the call-workflow portion of #54811.
Evidence
Workflow sample:
samples:
- workflow_name: "test-copilot-call-worker"
inputs:
sentinel: "${{ github.event.inputs.sentinel }}"
At github/gh-aw commit eaca36f, the replay server registers test_copilot_call_worker with metadata workflow: test-copilot-call-worker. apply_samples calls it with the sentinel and reports success. The apply stage then finds one call_workflow message but fails:
Workflow name is empty, skipping
Message 1 (call_workflow) failed: Workflow name is empty
The dynamic handler needs to materialize its _call_workflow_name metadata into the canonical field consumed by the apply handler, while preserving the sample inputs.

This overlaps with #54811 but is a follow-up rather than an exact duplicate. #54811 reported that the dynamic
call_workflowtool was not registered (Tool not found). Ateaca36f7a97c, registration and sample replay now succeed, but the replayed message loses the configured workflow identity and the apply stage fails withWorkflow name is empty. Keeping this issue focused on that post-registration serialization defect.dsyme commentedon Aug 26, 2026
Reopening because the same post-registration defect reproduces on gh-aw main at commit 818e3a3 with --use-samples. Replay emits and ingestion validates
{"inputs":{"sentinel":"..."},"workflow_name":"test-copilot-call-worker","type":"call_workflow"}, but the apply job still reportsWorkflow name is empty.
