# ICWDS C6-E3 Final Selective Joint Alignment

Formal path: `spectrum -> 10D semantics -> exact 30B v2 -> Direct -> residual LDM -> calibrated Gate -> Model`.

- Planned final training stage.
- Source C6-E2 SHA-256: `915d765c312eea705b8c696837eb07044605a0c97190538a016c672f9bcbbc3a`
- Spectrum AE and CNN segmentation backbone remain frozen.
- Late front semantics, exact-packet codec, conditioner and residual LDM are jointly aligned.
- The C6-E1 gate is frozen for epochs 1–2 and lightly recalibrated in epoch 3.
- After a passing training-freeze decision, the only remaining step is C6-F, a non-training final benchmark and archive audit.
