SPEC, DEV docs, and code comments still talked about the codebase as a rewrite-in-progress against an external prototype. With v1 shipped the framing reads oddly — it implies code is provisional when it's the production thing. Recast §18 as "the technical stack," strip "carryover from the prototype" comments across backend (api.py, chat.py, providers.py) and frontend (DiffView, PromptBar, SelectionTooltip, modelStyles), and rework SPEC §1 / §18 to introduce OHM up front rather than as a follow-on to a prototype reference. Also: - RUNBOOK: bump Python prereq to 3.11+ to match the production VM (was 3.13). - Remove IMPLEMENTATION-PROMPT.md — the original implementation brief is no longer load-bearing. - Add deploy/DEPLOY-NEW-SESSION-PROMPT.md as the durable deploy-handoff prompt for new sessions.
