# CAIN-A75-015 Context Integrity Review

**Verdict:** VERIFIED

> Checks a context-compaction record: source binding, compression ratio, verbatim retention of every must-retain item, no critical drop, no invented item and claim honesty. It does not judge summary quality.

| Record | Verdict | Ratio | Retained | Dropped | Failed checks |
|---|---|---|---|---|---|
| 0 | PRESERVED | 0.2 | 3 | ['F-background'] |  |

## What this proves and what it does not
- Proves: the compaction record is bound to its source, the summary is smaller within the declared ratio, every must-retain item is present with the same content hash, nothing critical was dropped, and no retained item was invented.
- Does not prove: that the summary preserves meaning, that the must-retain list was complete, or that the agent's next decision uses the retained context correctly.
