V-Belt Result Interpretation

V-Belt uses seven ordered classes.

Class	Meaning
`DROP_IN_FIT`	Identity-verified direct replacement.
`CORE_FIT_CONDITIONAL`	Same-section or explicitly compatible substitution requiring engineering review.
`CLOSE_MATCH_STRICT`	Same belt code and close length, but not drop-in.
`CLOSE_MATCH_CONDITIONAL`	Cross-construction close match requiring sign-off.
`CLOSE_MATCH_CROSS_FAMILY`	Cross-family close suggestion; never direct fit.
`UPGRADE_SUGGESTION`	Advisory performance upgrade.
`REJECTED`	Out of scope, ambiguous, unsafe, or failed gates.

Important tags:

Tag	Meaning
`NON_STANDARD_8VX_QUARANTINED`	8VX is quarantined from normal fit classes.
`CANONICAL_LENGTH_INCONSISTENT`	Canonical length evidence conflicts.
`ANTISTATIC_CAPABILITY_UNVERIFIED`	Antistatic capability is unknown.
`REQUIRES_ANTISTATIC_NOT_MET`	Required antistatic capability is not met.
`ARAMID_COMPATIBILITY_REQUIRED`	Aramid compatibility is required and not met.
`DRIVE_LOAD_TIER_UNDERSPEC`	Candidate is underspecified for drive demand.
`DRIVE_REQUIRES_ARAMID`	Drive requirements imply aramid is needed.
`DRIVE_REQUIREMENT_BLOCK`	Drive requirement blocks candidate.
`SECTION_COMPATIBILITY_DECLARED`	Same-section compatibility is explicitly declared.
`WRAPPED_COGGED_SUBSTITUTION`	Wrapped/cogged substitution path.
`CROSS_FAMILY_BRIDGE_DECLARED`	Cross-family bridge is explicitly declared.
`CLOSE_MATCH_LP_TOLERANCE`	Length is within close-match tolerance.
`CLOSE_MATCH_SECTION_GROUP`	Close match within section group.
`CLOSE_MATCH_CROSS_FAMILY`	Close match across family.
`COGGED_UPGRADE_SUGGESTION`	Cogged upgrade suggestion.
`CROSS_FAMILY_BLOCKED`	Cross-family substitution blocked.
