"""Airgap layer for OncoDSL.

Sits between the data layer (real gene symbols) and the engine (opaque IDs).
The GP engine sees only an `anonymise()`d view of the expression matrix so the
search can't lean on known gene-name priors — the MSI signature, if it emerges,
must be rediscovered from the data.

Public API:
- `anonymise(matrix)` — rename columns to opaque IDs g00001…; write the
  symbol<->ID map to `data/processed/_sealed_gene_map.json` on first call.
- `reveal(feature_ids)` — translate opaque IDs back. THE ONLY function allowed
  to open the sealed map. Must not be imported by the engine.
