Change impact
A capacity change can propagate through requirements, claims, dependencies, risks and decision gates. The system preserves the previous state rather than silently overwriting it.

Critical finding
CRITICAL
Conflicting plant capacity claimsThe controlled project contains both a 100 ML/day and a 120 ML/day capacity claim. An authoritative basis and verified evidence are required before gate progression.

Decision gate
BLOCKED
At least one critical requirement remains conflicting or insufficiently established.
This workspace demonstrates decision assurance. It does not replace qualified engineering, regulatory, environmental, financial or investment decisions.
