comparative-timing-overview-1.0.0 is a deterministic comparison layer over four separately governed chronology modules. It performs no astronomical recalculation and does not alter any source period.

Required inputs

• one active annual profection
• one active monthly profection
• three active Fortune releasing periods
• three active Spirit releasing periods
• one active Decennials major period
• one active Decennials subperiod
• one explicit UTC inspection instant

Containment and identity

Every lane must contain the inspection instant using a lower-inclusive and upper-exclusive interval. The output retains system, level, period, lord, start, end, family, and stable lane key. Exactly ten lanes are required; incomplete or mismatched input is rejected rather than supplemented.

Repeated-lord detection

The module groups identical traditional lords across all ten active lanes and returns only planets with more than one occurrence. Each occurrence retains its stable lane key, system, and level. No weight, score, ordering, or priority is added.

Regression boundaries

• A lane ending exactly at the inspection instant is not active.
• Fortune and Spirit lanes retain separate family identities even when their sign or lord repeats.
• Annual and monthly profections retain superior and subordinate labels.
• Decennials retains major and subordinate labels and its external apheta policy.
• The comparison emits no merged chronology or synthetic period boundary.
