The constraints index calls the invariants page a placeholder pointer; the page calls itself the canonical register

The constraints index calls the invariants page a placeholder pointer; the page calls itself the canonical register

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/02-constraints/README.md:12 — "Navigational pointer to invariant-shaped rules scattered across the brief (placeholder)"
• End B: .abcd/development/brief/02-constraints/03-invariants.md:3 — "This file is the canonical home for the project's invariants"

The constraints README describes 03-invariants.md as a navigational pointer to invariant-shaped rules scattered across the brief, and marks it a placeholder. The page itself is marked LIVE and says it is the canonical home for the project's invariants, with the other locations as cross-references and not the register. A reader following the index is sent away from the authority.
