nx_clm_lib.nx -- F996: CONTRACT LIFECYCLE -- obligation tracking + auto-renewal-trap detection. The expensive, silent contract failure is the EVERGREEN AUTO-RENEWAL TRAP: a contract renews for another (often costly) term unless you give written notice N days before expiry. Miss that window by a day and you are locked in. Legal teams miss it constantly because nothing computes the deadline and nothing flags the day it passes. This organ does both, and it is FAIL-CLOSED: a contract whose expiry or notice period is unknown is flagged FOR REVIEW, never silently reported safe -- because "no action needed" on a contract you could not evaluate is exactly how you get trapped. Dates are integer DAY-NUMBERS (deterministic, no float). Converting a YYYYMMDD to a day-number is the docketing engine's job (nx_docket); this takes day-numbers so the lifecycle math is exact and testable. SCALE ENVELOPE (declared): clm_overdue scans the obligation index for a contract's key-prefix (the proven per-key scan). DRY: composes nx_matter_lib (reg_*/mt_*/canon_encode). license_tier: ORIGINAL LIB.
