| DeLoRA | yes | normalized additive adapter with learned scalar |
| IA3 | yes | output gate initialized to ones |
| DoRA | yes, fp only | reads dense `weight` for column-norm; quantized DoRA fails loudly |
| SSVD / OFT / HRA / ROAD | no | planned after the hook-only invariant is clear |
| HRA | yes | output-side Householder reflection with identity gate; works on bnb |
| SSVD / OFT / ROAD | no | planned |
| S-steer / AntiPaSTO | no | should use data-calibrated `group_init`, not plain LoRA tests |
