PhysTwin fitted models: official author cases, photometric refinement

Project-produced photometric refinements of the supervised models the PhysTwin authors supplied, one folder per native source group, case and run, with every saved checkpoint and retained version.

What a run package contains

• native/: every saved checkpoint and state file of the run, byte for byte, with its run records and logs (CMA generations, candidates and strategy state; Adam snapshots, continuation state and per-update losses; or Deform360 boundary, optimizer, RNG and role records).
• evidence/: launch, parent-selection and qualification records that the run's records cite.
• run.json: stages, actual objectives, optimized and fixed parameters, configured versus completed budgets, labels with their scoring conditions, code revisions and dirty-state reports, capabilities and unknowns — each value names the native record it came from.
• checkpoints.tsv: one row per checkpoint file (stage, step, parent, labels, status, size, sha256).
• containers/: small native and evidence files packed by category into uncompressed tar containers of at most 1 GiB, bytes and logical paths unchanged (scaling plan §3.2, so a run stays within the Hub's file limits). containers/index.json lists each member's native path, offset, size and sha256 and the files kept individual; scripts/phystwin_publish.py fetch restores the native layout, by HTTP byte range for a single checkpoint.
• evidence/retained_versions/: older bytes of native records and state (earlier continuations, progress and selection versions, segment execution records and preserved delta bundles), each at its path in its original source, so no terminal name is overwritten.
• dependencies.json: model parents in this repository, dataset inputs to be pinned at a verified dataset revision, upstream archive members, and environment paths that are not package content.

Not claimed

• No model here was loaded, rendered, resumed or re-evaluated for this card.
• BEST and FINAL are the labels the fits recorded under their stated scoring conditions; packaging selects no preferred model. A completed budget does not certify optimizer integrity, fit quality or online readiness.
• The authors supplied no photometric model: each photometric stage is a project extension of their supervised model, whose tracking supervision is lineage, not this objective.
• Photometric continuation is not claimed (owner D21); extending a completed budget and full reproduction are not supported or claimed.
