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.
