Split monolithic model file

Extract and refactor code into separate files

Splitting a god-object into extensions while preserving stored properties and passing tests.

• · Workflow config

• · Structured phase results

• · Swift compiler
• · File grep/search

• · 2 hard constraints (stored properties unchanged, promotion only when cross-file needed)
• · Must run on shared working tree (no branch switch)
• · Ground-truth facts must be gathered before workflow starts

• · Build fails after refactoring
• · Test suite fails
• · Search/grep matches produce incomplete context
• · Git state mismatch if branch switched mid-run
• · Over-promotion of private members breaks encapsulation
• · Parallel agents produce inconsistent output

• · Adversarial verification phase verifies each finding
• · Parallel agents with deduplication + synthesis
