Forward Compatibility Over Backward Compatibility

Kind: algorithm

Record: algorithms:no-backward-compat

Canonical: Algorithms

Closure: Dependencies in load order

Replace accreted legacy input shapes with one forward-compatible envelope that carries extensions, so evolution compounds instead of branching.

Listed in Algorithm contracts, after Constraints Over Shortcuts and before Fail-Fast Over Fallback.
