Same-repo continuation of #277 — the NVSkills CI service rejects fork PRs, so this branch was created at the exact head commit of #277 to run /nvskills-ci. Authorship and DCO of @jensjebens's work are preserved.

Content state (verified on #277):

  • Skill directory is byte-exact from physical-ai-skill-hub-dev @ 889761b, including skill.oms.sig and skill-card.md
  • All 101 signature-manifest entries hash-match (0 mismatched, 0 missing, no unsigned extras)
  • DSSE envelope signature valid (ECDSA-P384/SHA384); cert chain pinned to the NVIDIA agent-signing root/ICA
  • content-integrity, metadata byte-stability, and benchmarks checks green

Plan: run /nvskills-ci here, merge, then close #277.

Source-side fixes by Jens Jebens: reference dedup (compare-profiles, mesh-fragmentation), hardened usd_validation_executor.py (schema-validated stdin, pinned interpreter/worker path, allowlisted getattr), Tier-3 evals.json reshaped to canonical schema, anti-refusal wording, SPDX comment headers removed.

Clears the two remaining SkillSpector Tier-1 false positives in
usd_validation_executor.py via variable renames only (no functional
change):

- TT5 critical: the tainted-flow check conflated the parent's
  subprocess.run(input=...) payload with the child's stdin variable
  purely by the name `job` -> renamed to `request_payload`.
- P6 high: `return rules` was flagged as system-prompt leakage; it is
  registry-shape probing -> renamed to `registered`.

Reproduced and verified against skillspector 2.5.0 by Jens Jebens:
security-scan PASS, 0 critical/high.
