Overview, and pointers to the canonical treatments

Overview: This companion does not restate Part I. The formal, canonical treatments of the recurring meta-topics live in the academic body and are referenced here once, so that a reviewer is never asked to read the same material twice.

This companion does not restate Part I. The formal, canonical treatments of the recurring meta-topics live in the academic body and are referenced here once, so that a reviewer is never asked to read the same material twice:

• One-line summary, and what is locked / derived / graded / not claimed. One SI anchor (632.99 nm ≡ mₑ by Compton) plus jamming geometry yields the constant family; the one-page map is §W.1 and Part 0.
• Provenance — where every number comes from: §W.6.
• The π-and-2 decoder (why π recurs): §5.0.
• Anticipated objections (A1–A8, B1–B2), resolved or flagged: §1.9.
• Falsification criteria / pseudoscience demarcation: §1.10.

What follows below is the material Part I does not contain: the convergence trail (v6–v8), the epistemic audit log (v25–v40), the 5-line reproducibility check, the common misreadings, and the meta-lessons for future reviewers.
