IFB Comms Beltpack Channel Tree Lookup

Audit actual directed IFB/comms routing graph from explicit caller root with reachability and return-to-root feedback witness; not audio feedback stability, hardware wiring or a universal station tree.

Description

A directed communications graph describes routing reachability.

A directed communications graph describes routing reachability. Return-to-root paths differ from general reachable cycles.^[1]

Enter unique nonblank stations, a matching square binary matrix and an existing root. Return reachable/unreachable IDs in input order and root-feedback flag.

When to use IFB Comms Beltpack Channel Tree Lookup

Use IFB Comms Beltpack Channel Tree Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. The flag does not detect cycles that never return to the root. No hardware routing or acoustic feedback stability is verified.

Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.

How to use IFB Comms Beltpack Channel Tree Lookup and understand its results

Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.
Enter stationIds, directedAudioRouteFlags, callerRootStationId using the field table and calculation rules, then run the tool.
Read rootReachableStationIds, unreachableStationIds, rootHasFeedbackCycle. 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
stationIds	Station ids	list of string	Required
directedAudioRouteFlags	Directed audio route flags	list of list of number	Required
callerRootStationId	Caller root station id	string	Required

Enter unique nonblank stations, a matching square binary matrix and an existing root. Return reachable/unreachable IDs in input order and root-feedback flag.

breadth-first traversal from exact root ID; flag reachable edge back to root

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

Output field	Meaning	Value type
rootReachableStationIds	Root reachable station ids	list of string
unreachableStationIds	Unreachable station ids	list of string
rootHasFeedbackCycle	Root has feedback cycle	boolean

Limitations and assumptions

The flag does not detect cycles that never return to the root. No hardware routing or acoustic feedback stability is verified.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Matrices are limited to 128 rows and 128 entries per row. 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. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use Cue Light System Stations Wiring Loop Lookup: Cue-light station evidence can show known channel mismatches or missing observations. The two states need separate outputs. For a complementary task, use Kabuki Drop Solenoid Release Line Count Tool: Release-point inventories identify which points depend on each circuit. Recorded release evidence is separate from physical synchronization.
