The first pass was written from the running server's own OpenAPI document and live probes. This adds what the source at tag v1.18.16 says, which changes three things. The names are transitional at BOTH ends. session.next.* is the event family of the rewritten event-sourced engine, landed in 1.15.0 (PR #27415); on the v2 branch all 36 events have already dropped the .next. and some are renamed outright — agent.switched becomes agent.selected, prompted becomes prompt.promoted. Those renames are v2-branch only and the 1.x line we run still emits the old names, so the guidance is to code against them but keep one mapping table. The schema package's own AGENTS.md says the V2 suffix is going too. Upstream calls the /api surface EXPERIMENTAL in its own title — "Experimental HttpApi surface for selected instance routes", version 0.0.1 — while /session/* is what the public docs document and is not deprecated. Worth writing down plainly: the internal direction is unambiguous, the external commitment is nil, and we would be building on a surface its authors have not committed to. The SDK is generated from the exact document we probed: the build script runs opencode's own generate and feeds it to hey-api, and @opencode-ai/sdk/v2 exposes the whole /api surface, takes a directory and injects it as both the header and the location query param. That is our hand-rolled SSE reader, both envelope unwrappers, three type sets and the model-id splitting, deleted. Also corrected by reading rather than guessing: permissions v2 is a real contract change (rules, requests and the reply all change shape, and free-text replies are gone) while questions v2 is a pure re-homing with identical fields — so they are not one piece of work. And the durable cursor's replay-then-live is gap-free by construction: it re-reads the database on every wake instead of draining a buffer, with the prompt response's admittedSeq as the first cursor.
