SRT Kit Weight Budget Calculator

Sum unique actual SRTgear inventory items, unknowns retained; duplicate IDsrejected, physical nonoverlap/completeness externally verified. No total-length accuracy or gear operational safety.

Description

An SRT kit mass inventory sums independently recorded gear items.

An SRT kit mass inventory sums independently recorded gear items.^[1]

Unknown item masses remain unresolved rather than being silently treated as a complete zero contribution.

When to use SRT Kit Weight Budget Calculator

Use this tool to obtain knownTotal, knownIds, unknownIds from the supplied records using the stated calculation. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.

How to use SRT Kit Weight Budget Calculator and understand its results

Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
Enter actualGearItemIds, actualGearMassesKg, itemEvidenceKnownFlags, using the field meanings and rules below, then run the tool.
Read knownTotal with knownIds and unknownIds. A known total does not complete an inventory whose records remain unknown.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
actualGearItemIds	Actual gear item ids	list of string	Required
actualGearMassesKg	Actual gear masses kg	list of number	Required
itemEvidenceKnownFlags	Item evidence known flags; binary 1 means the matched observation is known, 0 means unknown	list of number	Required

Supply nonempty aligned unique nonblank record IDs, nonnegative recorded contributions and binary known flags. Sum known contributions only and partition IDs into known and unknown lists in input order. An entirely unknown ledger returns zero known total alongside unknown IDs, not a complete zero exposure.

knownTotal=Σ(contribution_i where known_i=1)

Use the matching field units and the exact boundary, ordering and reference rules above.

Output field	Meaning	Value type
result	Qualified observed calculation or explicit reference	object
result.knownTotal	Sum of contributions marked known; this is not the total of unresolved contributions.	number
result.knownIds	Record identifiers whose contributions were marked known, in supplied order.	list
result.unknownIds	Record identifiers whose contributions remain unknown, in supplied order.	list

Limitations and assumptions

The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. String lists allow at most 128 entries of at most 128 UTF-16 units each; blank and duplicate rules are stated above. Extremely large composite outputs are rejected.
