Add focused integration coverage for real git branch freshness checks, degraded MCP startup reporting, policy routing, prompt misdelivery recovery, and telemetry JSONL roundtrips.
Constraint: Keep coverage isolated to new integration test files so existing in-progress workspace edits stay untouched
Rejected: Expand existing unit tests instead | user requested integration coverage across runtime and telemetry boundaries
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep these scenarios in integration tests because they depend on cross-module behavior and serialized output contracts
Tested: cargo test --workspace
Not-tested: Remote push hooks or CI-only environment differences
Add WorkerFailureKind::Provider variant and observe_completion() method
to classify degraded session completions as structured failures.
- Detects finish='unknown' + zero tokens as provider failure
- Detects finish='error' as provider failure
- Normal completions transition to Finished state
- 2 new tests verify classification behavior
This closes the gap where sessions complete but produce no output,
and the failure mode wasn't machine-readable for recovery policy.
ROADMAP P2.13 backlog item added.
