Poisson summation — five bridges, one theorem

Instrument audit — Poisson summation

Verdict. Collision. Five separate "bridges" in the dictionary turned out to be one theorem. A genuine collision, found by counting — which is the trigger OPS now names: audit whatever the dictionary uses most and examines least.

Where the reasoning is. Run in the genesis chat (72cc6f92-e583-4b1c-82a5-591c1be06e23), the thread that produced algebra-geometry-dictionary.md; the five uses and the reduction to one theorem are enumerated there, not here. This file records that the audit was run and what it found. Filed retroactively 2026-09-13 from notes/DIGEST-genesis-chat.md.
