# PAct OT Official-Init Pipeline QA

Date: 2026-05-21

This page publishes the official-initialized PAct pipeline QA run for the current
PAct x SceneTransporter route.

Key result:
- exported samples: 3
- QA passed: 3
- pass rate: 1.000
- minimum required pass rate: 0.750

What is packaged:
- Stage 1 uses the corrected official-initialized baseline checkpoint from the
  full OT ablation matrix.
- Stage 2 uses the spatial-diagnostics checkpoint, which preserves the vanilla
  PAct architecture and can be loaded by `PAct/infer_imgs.py`.
- The generated cache is
  `/data/250010098/PAct-Transporter/model_cache/pact_ot_official_stage1base_stage2diag_20260521`.

Boundary:
- OT-router checkpoints and the Stage2 spatial-adapter checkpoint are not
  directly loadable by the unmodified PAct inference pipeline yet because they
  contain wrapper or adapter parameters. They require the same runtime patching
  used in the trainer.
