Folio Deadline Section Pagination Order Lookup

Order observed section production deadlines while auditing actual folio interval collisions, preserving stable deadline ties; not automatic newspaper pagination or a universal section order.

Description

Section deadlines and folio collisions are separate production concerns.

Section deadlines and folio collisions are separate production concerns. Deadline sorting should preserve ties and original-index collision witnesses.^[1]

Enter aligned nonempty unique section IDs, whole-second UTC deadlines1900–2199, first folios1–1,000,000 and page counts 1–100000. Return stable deadline order/folios and original zero-based overlapping index pairs.

When to use Folio Deadline Section Pagination Order Lookup

Use Folio Deadline Section Pagination Order Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. Touching interval ends do not overlap; more than 128 witnesses fails. No automatic pagination or preferred section order is supplied.

Prepare the actual editorial, source, layout, timing or audience records requested. Supply explicit house-policy limits and preserve missing evidence.

How to use Folio Deadline Section Pagination Order Lookup and understand its results

Prepare the actual editorial, source, layout, timing or audience records requested. Supply explicit house-policy limits and preserve missing evidence.
Enter sectionIds, sectionDeadlineUtc, sectionFirstFolio, sectionPageCounts using the field table and calculation rules, then run the tool.
Read deadlineOrderedSectionIds, deadlineOrderedFirstFolios, overlappingFolioSectionIndexPairs. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
sectionIds	Section ids	list of string	Required
sectionDeadlineUtc	Section deadline utc	list of string	Required
sectionFirstFolio	Section first folio	list of number	Required
sectionPageCounts	Section page counts	list of number	Required

folio interval=[first,first+count); overlap if intervals intersect

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
deadlineOrderedSectionIds	Deadline ordered section ids	list of string
deadlineOrderedFirstFolios	Deadline ordered first folios	list of number
overlappingFolioSectionIndexPairs	Overlapping folio section index pairs	list of list of number

Limitations and assumptions

Touching interval ends do not overlap; more than 128 witnesses fails. No automatic pagination or preferred section order is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Rundown Backtime from Air Calculator: Backtiming derives a contiguous rundown from its fixed hard-out. Midnight crossings require complete UTC dates. For a complementary task, use Pull Quote Frequency per Page Guideline Lookup: Pull-quote placement records can be counted against known pages. Unknown page references should remain visible.
