kompress-v4 — Override Internalized (legacy)
The model that proved must-keep overrides can be internalized through self-labeling. Override delta collapsed to 0.000 — the model learned to keep critical tokens without explicit regex rules. Former production model. Now superseded by kompress-v8 (+0.012 heretic).
