User submits task:
  "In repo acme/retry-service, migrate RetryPolicy config from v1 to v2.
   Only modify config and related tests. Create a draft PR if verification passes."

System:
  1. validates user permission
  2. normalizes task contract
  3. checks repo policy
  4. schedules run
  5. creates sandbox
  6. clones repo at pinned SHA
  7. builds repo map
  8. prepares context
  9. plans migration
  10. edits files through file tools
  11. runs verifier
  12. repairs if needed
  13. runs policy checks
  14. runs LLM judge
  15. creates branch
  16. creates draft PR
  17. stores trace/artifacts
  18. emits final verdict

## Summary
Migrates RetryPolicy config from v1 to v2.

## Why
The v1 config format is deprecated by the migration task.

## Changes
- Updated `config/retry-policy.yaml`
- Updated RetryPolicy config loading test
- Removed remaining v1 config reference in test fixture

## Verification
- `mvn -q -DskipTests compile` ✅
- `mvn -q test` ✅
- `secret_scan_delta` ✅
- `diff_boundary` ✅

## Agent Evidence
- Task: `task_01jz...`
- Run: `run_01jz...`
- Base SHA: `abc123`
- Autonomy: draft PR
- Verifier profile: `java-maven-standard`
- Judge verdict: pass

## Review Notes
This PR is agent-generated and should be reviewed by the owning team before merge.

Given a task submission
When a run is created
Then the run enters QUEUED
And every state transition is persisted
And invalid transitions are rejected
And audit events are written

QUEUED -> VERIFYING must fail

If worker crashes after leasing a run
Then lease eventually expires
And another worker can resume or fail safely

update agent_run
set lease_owner = :worker,
    lease_expires_at = now() + interval '5 minutes',
    state = 'LEASED'
where id = (
  select id
  from agent_run
  where state = 'QUEUED'
  order by created_at
  for update skip locked
  limit 1
)
returning *;

Given repo acme/retry-service at main
When ingestion runs
Then it records exact base SHA
And all later diff/PR operations use that base

/workspace/
  repo/
  artifacts/
  tmp/
  policy/

A model may request file.apply_patch,
but only the runtime can apply it,
and only after path guard and policy decision pass.

The same agent loop can run with provider A or provider B
without changing domain state machine or tool runtime.

interface LlmClient {
    ModelResponse complete(ModelRequest request);
}

For a task touching RetryPolicy,
context contains relevant config/code/test slices,
not the entire repository.

When compile fails,
agent receives structured diagnostics with file/line/error cluster,
not only raw Maven log.

If diff modifies .github/workflows/build.yml for a config migration task,
policy blocks PR creation even if verifier passes.

If the same run retries after PR creation timeout,
it does not create duplicate PRs.

agent-pr:{task_id}:{run_id}:{base_sha}

Given a bad PR,
operator can open run trace and answer:
what task, what context, what tools, what diff, what verifier, what judge, what policy.
