Parse OSCQuery JSON tree into parameter map

[joaodotwork]

Description

Fetch and parse the OSCQuery JSON tree from VDMX's HTTP endpoint into a structured parameter map for the bridge to use.

Tasks

• Fetch OSCQuery root JSON via HTTP (urllib or requests)
• Recursively parse CONTENTS tree into flat parameter list
• Extract per-parameter: address, TYPE, RANGE (min/max), VALUE, ACCESS
• Filter to writable float parameters (ACCESS includes write, TYPE is "f")
• Build parameter map: {name: {address, type, min, max, value}}
• Support periodic refresh to pick up new parameters

Acceptance Criteria

• Produces a complete parameter map from VDMX's OSCQuery tree
• Handles nested Control Surface structures
• Correctly parses normalized 0.0–1.0 ranges and custom ISF shader ranges

• ACCESS: 1 = read-only, 2 = write-only, 3 = read-write
