tiltmeter — development disclosure

This project is developed with substantial AI assistance (Anthropic Claude),
under human direction and review. Methodology decisions are recorded in
docs/decisions/ with their rationale and sources regardless of who or what
drafted them; the auditability guarantees in METHODOLOGY.md are enforced by
CI, not by trust in any author, human or otherwise.

Consistent with the project's disclosure policy, AI use is declared here in
the repository rather than in individual commit messages.
