/**
* P4 first-run scaffold — E2E (periodic tier, ~$0.02 each, deterministic).
*
* Exercises bin/gstack-first-task-detect END-TO-END through the real runner +
* hermetic env (path resolution, execution, git-in-cwd), not just the unit
* harness. Deterministic by construction: it asserts the binary's enum token
* from the Bash tool_result in the stream-json transcript (never the model's
* prose), so it pins the detector's integration contract without depending on
* non-deterministic model phrasing.
*
* Periodic (not gate): onboarding behavior is non-safety, and the scaffold
* marker is model-touched (best-effort). The deterministic bucket logic itself
* is fully covered by the unit test (test/preamble-first-task-scaffold.test.ts).
