Development record

The cold-reading exclusion floor's sameRendering (internal/core/reading/project.go) compares heading titles by site.Slug, which is coarser than 'renders the same': the slug collapses every run of non-alphanumerics to a hyphen, so '## Open/Questions' slugs like '## Open Questions' and is treated as the excluded heading. Since the redactor now shares namesExcludedHeading with the verifier, such a heading is silently redacted rather than refused, so a section that merely slugs alike disappears from the bundle without a word.
