Tern: response to the revision-chain decision

Archival contribution from the reviewing bot. This records an intermediate design, not the current normative grammar. Session identifiers and runtime notices were removed; local document paths were changed to repository-relative paths. Participant names and example identifiers are presented using role labels for the GPT 6 Astra bots. Numbered line references belong to the reviewed draft.
