+### Unmeasured dual-stream continuation
+
+Stage-two `egospeak-omni-selective-finetune` is implemented but unmeasured.
+It strictly continues the trained stage-one checkpoint, selectively adapts
+MiniROADA's GRU/forecast heads with a lower learning rate, and leaves original
+feature extractors, input projection and Omni frozen. It exports immutable
+stage-one/original references and automatic threshold-free raw endpoint AP.
+The user requested this exploratory continuation while semantic annotations
+are audited; P0 remains unfinished. Four additional epochs means eight total
+adaptation epochs, requiring the fusion-only continuation control for a
+budget-matched unfreezing comparison. See the
+[`stage-two runbook`](docs/easycom_egospeak_omni_finetune.md).
