Establish research snapshot 2026.08.12

[DearKarl]

Summary

• establish the 2026.08.12 research snapshot and project-wide CalVer convention
• rewrite README and contributor guidance around Canonical Table, Explicit, and LoRA research tracks
• publish the Explicit topology interface and method note
• rename the Python package and project-authored schemas and identifiers
• remove internal coordination contracts and sealed internal evidence from the current public tree

Rationale

The repository now presents a research-oriented collaboration surface with consistent artifact naming and without business targets or internal execution terminology.

Validation

• 18 data-free tests pass on Python 3.12
• JSON Schema parses successfully
• Python sources and tests compile successfully
• staged-tree scan found no internal contract names, project-owned legacy version identifiers, credentials, or restricted artifact hashes
