sessions: OpenCode v2's sessions are read (Kumo31: opencode v2的session改写到新表里了) — OpenCode 2 (v2.0.x, checked against v2.0.18's source) keeps sessions in the same opencode.db but in tables of its own (packages/core/src/session/sql.ts): session_v2 (the session row as before — directory, parent_id, a title that may now be null, time_created/updated, model {id, providerID, variant}, session totals) and session_message (id, session_id, type, seq, time_created/updated, data), not "sessionmessage". A message's kind is its type column (user, assistant, synthetic, system, compaction, idle, …); a user message's data is its prompt {text, files, …} with no part rows; an assistant's has model {id, providerID, variant}, content (text/reasoning/tool), cost, tokens {input, output, reasoning, cache {read, write}} and time {created, completed} (packages/schema/src/session-message.ts, token-usage.ts), counted as before: input without the cache, output without the reasoning (core/src/session/usage.ts). A compaction carries its own tokens, counted on its model, else the one last replied with. On first start OpenCode 2 copies every old session over (core/src/database/v1-migration.bun.ts), leaving session/message/part unwritten and recording kv migration.v1-v2 {"phase":"completed"}; so with session_v2 present only it is read once that is recorded (or no old table is left, as for the pre-split v2 databases it renamed in place), and while the copy is under way an old session not yet in session_v2 is read from the old tables — never both, so nothing counts twice and a session deleted in v2 doesn't come back. Resume stays opencode --session <ses…> (cli/src/commands/commands.ts). Tested with a v2 fixture made in the test from SQL beside stale old tables; the old-table and JSON-file tests still pass.
