Coverage badge claims 100% but CI gate enforces only 95%

[sophiecarreras]

Summary

The README badge and DEVELOPMENT.md both claim 100% test coverage, but the actual CI threshold is 95% statements / 85% branches. This is an active credibility gap — a contributor reading the docs gets a false signal about the project's quality bar.

Evidence

• README badge: static string coverage-100%25-brightgreen
• DEVELOPMENT.md: "100% statements/branches/functions/lines across 156 tests, zero v8 ignore annotations"
• Actual CI gate (vitest.config.ts / coverage thresholds): ≥95% statements, ≥85% branches

Acceptance criteria

• Either raise the CI gate to 100% (and keep the badge), or update the badge and DEVELOPMENT.md to reflect the actual enforced threshold
