Module path 

Source
Expand description

Conversion path solver — find the optimal (source, operation, output) path.

Given a source format, an operation category, and an output format, the solver finds the cheapest conversion chain that satisfies quality constraints.

The algorithm:

  1. Get the operation’s OpRequirement
  2. Generate candidate working formats
  3. For each candidate: compute source→working cost + suitability + working→output cost
  4. Filter by quality threshold
  5. Pick lowest total cost among qualifying paths
