PhysEdit/PAWBench-A09-Ratio-Control-Data

PAWBench A-09 ratio-control candidate-video staging (Issue #298)

Collaborator-writable staging surface for the A-09 model-level ratio-control case study (PhysEdit#293, execution issue #298). This repo realizes the candidate_data location proposed by staging_locations.json in the #297 input package; it lives under the PhysEdit org (public) by operator decision of 2026-07-13 because the proposed Andrew613 repos were never created and private quota was unavailable.

What this repository contains

• candidate_videos/ — Seedance 2.0 first/last-frame candidate training videos for scene A-09, named by frozen sample_id. The formal denominator is exactly 200 rows (40 endpoint controls x 5 seed identities). Videos appear here as soon as they are generated, before any usability filtering, per the #298 upload-before-exclusion contract.
• manifests/candidate_ledger.jsonl — one terminal-status row per planned sample (schema: candidate_ledger.schema.json from the #297 package), updated at each phase boundary.
• receipts/ — phase receipts, launch authorization (with live price quote, provider schema deviations, and the fal-storage input-transport fallback), and the hash-bound fal staging map.
• review/ — canary visual-review contact sheet and motion strips.

What this repository is NOT

• These are candidate training-data videos, not PAWBench benchmark inputs, not accepted training data (acceptance is a separate reviewed gate), not model outputs under evaluation, and not evidence that any training approach achieves probabilistic alignment.
• No usability decision is implied by a video's presence here. The accepted bank and failure manifests are separate, later artifacts.
• No PAWEval result, checkpoint, metric, or paper-facing claim lives here.

Provenance

• Input authority: Andrew613/PAWBench-A09-LastFrames @ 800521f1cc6332cd834632a1ecdecb81b17937e4 (normalized A-09 first frame, 40 terminal-frame controls, frozen 200-row generation plan, frozen Seedance 2.0 request profile).
• Generator: fal.ai bytedance/seedance-2.0/image-to-video, standard tier, 720p, 5 s, aspect_ratio=auto, audio disabled, direction-neutral frozen prompt. The provider exposes no seed parameter; planned seed identities are sample identities (provider-returned seeds are recorded in the run sidecar).
• Runner: projects/pawbench/tools/a09_ratio_control/run_seedance_candidate_grid.py on branch task/pawbench/0298_seedance_bank of PhysEdit.
• Every video is hash-bound to its plan row (first-frame hash, endpoint hash, prompt hash, request-profile hash) in the candidate ledger; SHA256SUMS covers the uploaded files.

No credentials or secrets are stored here; receipts record credential environment variable names only.
