PhysTwin fitted models: DAIRLab lab sessions

Complete project-produced PhysTwin-style spring-mass fits of DAIRLab/phystwin_dataset lab sessions, one folder per recorded session and fit run, with every saved checkpoint.

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.
• 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; clean-destination use is a separate validated step (plan PR4).
• BEST and FINAL are the labels the fits recorded under their stated scoring conditions; packaging selects no preferred model.
• Interrupted-run recovery is qualified by each run's recorded execution identity and inputs; extending a completed run's horizon and full reproduction are not supported or claimed.
• Historical clamp-at-use stiffness runs are not reinterpreted as projected-update runs.
