## Why
A completed Phase 2 agent run does not guarantee that its required outputs were
created correctly. Treating a clean workspace as success can also preserve a
state where those outputs are missing.
## What changed
- Require `MEMORY.md` to be a file and `memory_summary.md` to start with `v1`
before marking consolidation successful.
- Fail completed runs with invalid artifacts without resetting the workspace
baseline, allowing the job to be retried.
- Run consolidation for a clean workspace when its required artifacts are
invalid instead of taking the no-change success path.
## Testing
Added coverage for rejecting an invalid summary and retrying a clean workspace
whose consolidation artifacts are missing.
