[OVVO-Financial]

This PR records a direct R behavior fidelity check from
OVVO-Financial/NNS to OVVO-Financial/NNS-python.

R commit: 7dec0a0e39ec9e604b9e9c47c7ecf2d99673abf0
R version: 13.1
R src tree hash: bb79a1cb8c4bb838b2f715b0118f7413fa61f6c0
DESCRIPTION changed: false
Fresh cache requested: false

Reports:

• sync/last_r_api_inspection.md
• sync/last_r_api_plan.json
• sync/last_live_r_parity_report.md

Native code still enters Python only through NNS-core. But public
Python behavior must match live R NNS at the recorded R commit,
including wrappers, defaults, return shapes, and exported function
behavior.

If DESCRIPTION changed and fresh cache was not requested, run this
workflow manually with fresh_cache=true.
