⚠️ Ambiguous steer failures duplicate instructions
When session.prompt commits but its response is lost, steerWithOptions queues the same instruction as refused. The fallback uses a new provider identity, so OpenCode executes it twice.

🟡 Child provider marks stay stale
When session refresh first resolves a child, resolveSpawnedChatProvider leaves the transcript memo props unchanged. The memoized list skips rendering, so its provider mark stays on the parent until another transcript change.
Learn more
The callback reads current sessions only when a transcript render invokes it. Its identity never changes, so a sessions-only refresh does not invalidate the memoized AgentChatMessageList. This commonly occurs when a spawned child is absent from the initial list and appears in the next refresh.
Example: A Claude parent first renders child child-9 before that child is listed, so the card falls back to Claude. The refresh adds child-9 with provider codex, but the card remains Claude until a new chat event arrives.
Recommended fix: Derive a memoized child-session provider map from sessions and pass a resolver whose identity changes when that map changes, or pass a provider-version primitive that invalidates the transcript memo.

Preserve partial deltas for one reasoning item.
When a hidden context_usage row separates two deltas for the same reasoning item, collapse leaves two rows. Visible-row filtering makes them adjacent here. mergeReasoningTextFragments then trims the deltas and inserts ---, so "Hello " and "world" render as separate Markdown blocks instead of "Hello world". Merge repeated (itemId, summaryIndex) fragments with mergeReasoningFragment before applying list-level deduplication for distinct reasoning items. Add a test with a hidden snapshot between same-item deltas.

Do not use text containment as proof of a reasoning replay.
Valid deltas and separate provider blocks can repeat or contain the same text. The current logic removes that text without event-level evidence. For example, two "ha" deltas become one "ha".

Problem
The OpenCode harness was second-class in ADE: full-auto still raised approval cards for paths outside the worktree, a message typed mid-turn could not fold into the running turn, and an OpenCode tool returning a screenshot rendered as "Image generated" with the raw base64 data URI printed as its name. Separately, a turn's reasoning could render as two
Thoughtrows or one doubled paragraph.Cause
OpenCode had no inline active-turn steer path and no in-flight steer ownership, so a queued row could race the turn tail and a mid-turn message waited for the whole turn. Every OpenCode
filepart was labeled a generation regardless of who owned it, so a tool-returned image claimed to have been made by the model. Full-auto never statedexternal_directory, leaving OpenCode's default "ask" in force on a mode whose promise is no prompts.Change and boundary
session.promptdelivery: "steer"input with a server-brandedmsg_admission id (a bare UUID 400s and would silently degrade every inline steer to the queue). Staged promotion, idle queue drain, and in-flight row protection are shared with Codex/Cursor; the turn-boundary drain guard now covers every runtime that tracksdispatchingSteerIds. The v2 prompt carries text and file parts only, so a per-message reasoning/execution/interaction override cannot ride it — those rows stage for the turn boundary instead, mirroring Cursor's refusal.external_directory: "allow"(a{pattern:"*"}rule appended after OpenCode's built-ins), which grants unrestricted external read/write — the point of full auto. The comment anddocs/features/chat/README.mdstate that blast radius accurately.filepart is model output (codex_image_generation); a tool attachment is a view (codex_image_view) unless the tool is a recognized image-generation tool. The view line previewsdata:URIs inline only (the renderer CSP pinsimg-src, so a remote preview would paint an empty box), never prints base64 as a name, and keepsopenfor remote/local sources.

Note
Medium Risk
Changes touch live-turn message delivery, queue/dispatch lifecycle, and permission rules for OpenCode sessions—areas where races or mis-routing could drop or duplicate user messages, though coverage is extensive in agentChatService tests.
Overview
OpenCode now supports inline active-turn steering via the v2
session.promptpath withdelivery: "steer"and brandedmsg_admission ids, plus staged promotion, in-flight dispatch protection, queue fallback when delivery is refused, and the same per-message override staging rules as Cursor. The shared dispatch table, CLI help, and TUI/steer sendpalette treat OpenCode like Codex (inline + queue, no interrupt).Full-auto OpenCode sets
external_directory: "allow"so reads outside the worktree no longer raise approval cards; other permission modes still omit that key.Image presentation splits OpenCode assistant
fileparts (generation) from tool attachments (view), adds sharedisDataUri/isRemoteOrDataUrihelpers, avoids printing base64 as titles in TUI/desktop, and previews data-URI views inline where CSP allows.Claude reasoning is deduped when stream indices disagree with SDK snapshots; transcript grouping merges same-turn thought rows with duplicate-aware fragment merging and drops hidden
context_usagerows before grouping so anchors and Thought rows stay aligned.UI polish: subagent spawn/result cards show the owning runtime provider mark; Codex local-path detection uses the shared remote/data predicate.
