Strict collateral governance trades initial overhead for fewer escapes.
+------------------+----------------+----------------+----------------+
| Approach | Strength | Weakness | Best when |
+------------------+----------------+----------------+----------------+
| Strict | predictable | slower early | new program |
| Balanced | practical | needs rigor | stable teams |
| Aggressive | fast | escape risk | late schedule |
| Re-architect | durable | expensive | recurring failures |
+------------------+----------------+----------------+----------------+Pick the approach based on residual silicon risk, not only schedule pressure.

INTEGRATION EVIDENCE MATRIX — Abstract Models (LEF/DEF/Timing)
+-------------------+------------------------+--------------------------+-------------------------+
| Evidence | Tells you | Does not prove | Next action |
+-------------------+------------------------+--------------------------+-------------------------+
| Manifest diff | baseline changed | root cause itself | isolate first delta |
| Domain trace | where behavior diverged| ownership accountability | map to contract owner |
| Signoff dashboard | closure posture | reproducibility quality | verify source artifacts |
| Bring-up logs | software-visible symptom| physical/timing cause | correlate with HW trace |
| Waiver register | accepted residual risk | technical closure | review expiry criteria |

Correlate issue to owner boundary
Ask: what baseline, owner, and artifact prove this topic is truly closed?
State baseline manifest and owner with every closure metric.
Run cross-domain regression after every top-level fix.
Comparing results across different manifests.
Unowned issues slipping through review cycles.
Waiving risks without expiry and validation plan.
Top-level integration relies on abstract views (timing, physical, power) that must remain aligned with evolving implementation details.
Metric: abstract-model mismatch defects, floorplan integration churn
