Why

PUT /v1/admin/runs/{id}/paused answers 409 route and stored contract version differ for every v2 run, because ChallengeStore.set_paused starts with self._run(...), which rejects v2 manifests. On production this means the non-live v2 runs cannot be paused through the admin API (a direct SQL update was ruled out), so /public/v1/runs keeps listing them as running although they cannot be served.

What

For a v2 run, set_paused now makes a display-only flip running <-> paused: no v1 config, beacon or round-0 branch is touched. It refuses a run that is not in the expected source state (409), notably a created run, so un-pausing can never start a run that has not opened a round. open_round_v2 still sets running.

Evidence

test_admin_pause_flips_only_an_opened_v2_run_without_touching_its_state fails on the base with 409 route and stored contract version differ and passes with the change (re-run here: 1 passed vs 1 failed). The session ran the surrounding suites: 182 passed (test_service_network_v2.py, test_rounds.py, test_contract.py) plus test_multirun.py; ruff and mypy clean.

Risk / rollback

v2 only; v1 behaviour unchanged. The status of a v2 run is only read by the public view. Rollback: revert the merge commit. After rollout: PUT .../paused {"paused": true} for the stale runs, {"paused": false} to undo.

Summary by CodeRabbit

• Bug Fixes
  • Updated pause and resume behavior for version 2 runs to allow only valid transitions between running and paused states.
  • Prevented pausing or resuming runs that have not yet started.
  • Ensured pausing and resuming version 2 runs changes only their status without altering associated run data.

Review notes (Lens, 0 blocking / 0 important)

• paused on a v2 run is a display label only: no reader of runs.status blocks rounds, grants or audits for v2 (_run_v2 reads only the manifest; configure and aggregate go through _run() and still 409 on v2). open_round_v2 sets running again.
• Idempotent: running->paused, paused->paused, paused->running and running->running all return 200. 409 only for created, completed, stopped or unknown status.
• Expected side effect: the public view maps paused to stopped (public_api/views.py:217), so a paused v2 run is listed as stopped with an endedAt on /public/v1/runs. This is what lets the list show a single running run.
• Mutations checked: removing the manifest_version == 2 test makes 8 v1 tests in test_rounds.py fail; removing the created guard fails the new test.

📝 Walkthrough

Manifest-v2 runs now allow pause and resume only between running and paused. Other current statuses return a 409 error. Legacy runs retain their existing behavior.

Changes: Manifest-v2 run pause handling

Layer / File(s)	Summary
Validate and test v2 pause transitions src/hypertrain/challenge/store.py, tests/challenge/test_service_network_v2.py	The store permits running↔paused status changes and rejects other current statuses with a 409 error. The integration test verifies the status responses and confirms the manifest and envelope remain unchanged.

Change: Bug fix

Merge Risk: 🔵 Low · up to c4976

Pause and resume appear mergeable with bounded risk, but the new test should exercise an opened v2 round so it protects that state against regressions.

4449-4470: 🎯 Functional Correctness | 🔵 Trivial | 🏗️ Heavy lift

Open the v2 round through its supported lifecycle before pausing.

The fixture creates the v2 run but does not open a round. The test only sets runs.status to running, then compares manifest and envelope. It does not exercise POST /v2/runs/{id}/admin/rounds, or inspect round-0 records and beacon_pins_v2.

A pause implementation that changes opened-round state or beacon data can pass this test. Submit a valid RoundOpenV2 through the supported route first, then snapshot and compare the v2 round and beacon state across pause and resume. The existing v1 lifecycle test does not cover this v2 route.
