desk notes
Verified 2026-10-16. Active repository, 0 stars/0 forks, no tagged release. README now explicitly distinguishes shipped behavior from gaps: agent-issued live reads pass through guard(), but hand-written SQL has no service/CLI path into the fence, reviewer-owned live reads bypass it, and persistent diagnostic runs are not yet built. Repository reports 138 QA cases in the Oct. 16 documentation commit.
