The TUI message store caps at 100 entries for rendering performance; /export and /copy were reading from that store, producing truncated transcripts on compacted or long sessions. Fetch all messages from the server via a testable helper with no limit. Authored-By: OpenCode (anthropic/claude-sonnet-4-6)

Summary
The TUI
/exportand/copycommands read from an in-memory message store capped at 100 entries for rendering performance. On sessions with compaction or more than 100 messages, this silently truncates the transcript — pre-compaction messages are stored in the database but never fetched.The fix fetches all messages directly from the server for transcript generation, matching what the CLI
opencode exportcommand already does correctly.Root cause
packages/opencode/src/cli/cmd/tui/context/sync.tsxinitialises the store withlimit: 100(newest 100 messages only) and evicts the oldest message whenever the store exceeds 100 entries. Bothsession.copyandsession.exportread from this store viamessages().Fix
Replace
messages()(in-memory store) withawait sdk.client.session.messages({ sessionID })(server fetch, no limit) in both handlers. Includes a unit test covering the >100-message and pre-compaction cases.Closes anomalyco#16765
