…reattach, root-TUI CLI OpenCode chats echoed every outbound prompt back as agent output because user-message parts streamed through the same event as assistant content; text/reasoning/file emission now requires a known assistant message role. Session reattach only falls through to a fresh session on a confirmed 404 — transient errors used to silently reset live threads onto empty sessions. System prompts ride the prompt body's first-class system field; the old synthetic+ignored part injection never reached the model at all. Tracked OpenCode CLI launches always start the full root TUI (run --interactive's bare split-footer read as a broken plain terminal), replay resume uses root --mini with --replay-limit, and the resume-target backfill matches directories through realpath-resolved platform keys so /var vs /private/var stops stranding sessions. Placeholder titles no longer adopt. Pinned opencode-ai/@opencode-ai/sdk at 1.18.21.

- Around line 23524-23525: Reorder the OpenCode chat flow so openCodeEventStream
and its event subscription are established before promptAsync dispatches the
prompt. Preserve the existing role-map handling in the event subscriber,
ensuring message.updated events can register assistant and user IDs before
subsequent text, reasoning, and file events are processed.

status before accepting a 404 or NotFoundError match. Ensure a wrapper named
NotFoundError containing a nested non-404 status is rejected, while preserving
true results for genuinely 404-only chains, and add a regression test in the

…4 check, working replay gate
Review findings from Codex + CodeRabbit, all verified against code:
- Subscribe to the live-only SSE stream BEFORE dispatching the prompt; a
prompt that won the race lost its assistant message.updated role
announcement and the new gate would have dropped the whole message.
- isOpenCodeNotFoundError now runs a two-pass bounded walk so a nested
non-404 status vetoes a shallow NotFoundError name (no session reset on
{ name: NotFoundError, cause: { status: 503 } }).
- The mini-replay support probe used \\b--flag\\b, which can never match
because '-' is a non-word character; anchor on whitespace edges instead.
Replay resume was permanently dormant. Pinned with realistic help output.

Note
Medium Risk
Touches OpenCode session re-attach, prompt delivery, and transcript rendering — a misclassified 404 or role gate can lose context or hide assistant output. CLI launch/resume argv also changes, so Work terminals depend on the new 1.18.21 flag surface.
Overview
Bumps OpenCode to 1.18.21 and fixes several silent-wrong behaviors in chat and tracked CLI.
Chat runtime: ADE system prompts now go on the prompt body's first-class
systemfield. The old synthetic/ignoredtext part never reached the model. Stream rendering keys message roles frommessage.updatedand only emits text/reasoning/file parts for assistant messages, so user prompt echoes no longer appear as agent bubbles. Placeholder titles (New session - <ISO>,Child session) are ignored so auto-titling can still run.Session continuity: Re-attach recreates a session only on a confirmed 404/
NotFoundError. Transport/timeout/non-404 failures now surface instead of starting an empty thread.Tracked CLI: Fresh launches always use the root TUI (
opencode --prompt …) — norun --interactiveand no--variant(fast/reasoning stay chat-only). Replay resume is--mini --replay-limit(explicit--replayis an upstream error). Resume-target matching uses realpath +pathKeyso macOS/tmpvs/private/tmpno longer drops lane resume IDs.Reviewed by Cursor Bugbot for commit 728af0c. Configure here.
