Implement explicit Base FL2VA and Ref2VA profiles, sigma node and native workflow contracts; add Diffusers and ComfyUI-native parity runners, golden evidence, CI jobs, compatibility contracts, and package/release updates.
Progress: tracked index and reviewed .secrets.baseline reconciled across 56 public paths; performance matrix regenerated; local Diffusers and native ComfyUI H3 parity PASS; wheel audit PASS (102 files, zero mandatory runtime dependencies). Linux full gate passed pre-pytest stages and reached 2603 passed, 3 skipped, 2 failed.
Blockers: the remaining pytest failures are stale native-Windows receipt/matrix fingerprints; this WSL environment cannot execute powershell.exe, cmd.exe, wsl.exe, or PE32+ Windows Python. Hosted Actions evidence is unavailable because GH_TOKEN is invalid. Canonical pinned H1/H2 was not launched because reference/ComfyUI requires comfy-aimdo==0.4.11 while the selected executable environment has 0.4.10.
Handoff: regenerate tests/compatibility/fixtures/windows_py313_v1.json natively, regenerate/check the derived compatibility matrix, rerun the Linux full gate, publish the candidate through authenticated hosted CI, then run scripts/run_comfyui_e2e.py --minimax-h3-only against ComfyUI 14b05228 with comfy-aimdo==0.4.11. Keep M6-05 IN_PROGRESS until all gates pass. Detailed local-only records remain in ignored .planning/ and reference/; no weights or credentials are included.
