- Around line 42098-42099: Update openCodeFailureMessage to redact sensitive
spans from upstream error details before returning them, ensuring notification
and Feed error fields receive only sanitized text. If redaction leaves no safe
detail, return the existing safe product-level fallback.
- Line 36654: Make session state the source of truth for stop deduplication:
track the admitted user-message identity and clear `lastStopKind` only when a
distinct turn starts. Update the user-message handling and `resetTurnFromEvent`
so repeated updates or busy status for the same turn preserve the recorded stop;
verify a repeated update followed by idle does not emit a second stop.
Review comments at @cmux-tui/crates/cmux-tui-core/src/agent_hooks.rs:
- Line 302: Update the event mapping around `sessionexecutionsucceeded` and
`sessionexecutioninterrupted` to inspect the structured interruption reason and
avoid emitting `agent.turn.completed` for shutdown interruptions, while
preserving completion behavior for other interruptions. Add a regression test
verifying a shutdown interruption does not complete the turn.
Review comments at @Resources/opencode-plugin.js:
- Around line 748-750: Update the stop-outcome logic in
Resources/opencode-plugin.js at lines 748–750 to settle one authoritative
terminal outcome per turn before dispatch, preventing a later failure from
reclassifying an already-published success. Apply the same settlement rule in
Resources/opencode-tui-plugin.js at lines 239–244 before dispatching the hook,
and cover the idle-then-error ordering in lifecycle tests.

Released OpenCode (1.x and the dev channel) loads cmux through each
plugin's default server(ctx) entry inside the TUI process. Those entries
returned {}, so no lifecycle event reached cmux. Subscribe when the TUI
process server context is present, once per process.

Resolve the TUI bridge against #20441: keep its queued session-start retry and route stop settlement through a per-session turn ledger, so a turn publishes one terminal stop and only a new turn identity reopens it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A turn now settles on its first terminal event and is reopened only by a turn identity the session has not seen (a new user message or prompt). Repeated message updates and busy status no longer clear the recorded stop, and a failure after a published idle stop is dropped instead of producing a second notification. Applies to the Feed bridge and the session plugin source. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
OpenCode error text reaches notifications and Feed error fields. Redact credentials, bearer tokens, JWTs and emails first, keep paths and model names readable, and fall back to product copy when nothing safe remains. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
On OpenCode 1.x the TUI process argv is [opencode, /$bunfs/root/src/index.js], and the sanitizer only dropped the V2 TUI worker entry, so restore replayed the Bun virtual path as a project directory. Drop any Bun virtual entry. Also stop reusing an inherited launch capture that describes another agent, which recorded e.g. a Claude command for an OpenCode session started from a Claude shell.

No workflow names tests/test_opencode_server_entry.py, so the registry guard rejected its linux-guard lane. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The process-global guards blocked a reinitialized plugin scope from subscribing again. Key the owner on the plugin ctx, which every loader in one scope shares, and replace the previous feed when it changes. The regression harness now waits on a session.deleted sentinel instead of a fixed delay and keeps its socket in the temporary directory. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A queued prompt's admission and user message arrive while the previous turn is still running, so keying turns on first-seen message IDs dropped the stop for the queued turn. Open a turn only on a run signal (session creation, busy status, a promoted prompt or an execution start) in all three bridges; a repeated message update after a stop still cannot reopen the turn. The TUI bridge tracks turn starts before its ownership check so a turn that starts in a hidden tab keeps its stop. Also: - Do not publish a stop for an execution interrupted by shutdown, which OpenCode resumes, matching cmux-tui. - Redact credentials in the Feed plugin's own failure text, which reaches Feed without passing through the CLI. - Drop inherited subrouter and routed-account launch keys when recapturing OpenCode's own launch.

Drive a prompt that is admitted during a running turn and promoted after its stop, a repeated user-message update after a stop, a late failure, and a shutdown interruption through the session plugin and the Feed bridge. Wait for a session-end sentinel before counting so a late extra stop is caught. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
An OpenCode started from another OpenCode inherited the parent's opencode launch capture and recorded the parent's resume command. Always capture this process's launch; no cmux wrapper exports one. OpenCode never disposes a replaced plugin scope's hooks, so the session bridge now ignores events once a new scope owns the process. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A raw session.error, session.execution.failed or session.next.step.failed stop made the notification an error but reached Feed as a successful Stop. Both paths now use one predicate. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

OpenCode publishes session.error for a user interrupt (MessageAbortedError) and a recoverable context overflow (ContextOverflowError), then goes idle. These turned an Esc into a red error notification. The bridges now let the idle stop decide the outcome. OpenCode keeps one plugin scope per directory and disposes a scope's hooks on teardown, so dedupe only within one ctx instead of evicting the other live scope.

The main cause: released OpenCode (1.19.0 on npm
latest, and the current dev channel) loads cmux through each plugin's defaultserver(ctx)entry, inside the TUI process. Since #18659 those entries returned{}. Per-TUI delivery was moved to a./tuiexport that 1.x only loads fromtui.json, which cmux never writes, and that export callsctx.data.listen, an API 1.x does not provide. A real OpenCode 1.19 turn sent zero socket frames and zero hook calls to cmux. The server entries now subscribe when they receive the TUI-process server context (client,serverUrl,directory). OpenCode loadscmux-feed.js,cmux-session.js, andplugins/cmux/index.js. Their ownership is keyed on the pluginctx, which every loader in one scope shares, so the three entries deliver one start and one stop per turn between them. A reinitialized scope, which gets a newctx, subscribes again. Calls without that context (old V2 snapshots' shared service) stay inert.OpenCode hooks were reaching cmux, but current lifecycle events were folded incorrectly and plugin installation could target the wrong config directory. Non-archived
session.updatedevents reopened sessions, idle forms emitted duplicate stops, andsession.error/session.next.step.failedwere ignored or classified as successful stops. The app then lost the failed turn's sidebar and unread/error state.This updates both OpenCode bridges for current event shapes. Each turn now produces one start and one completion, duplicate idle/status events are coalesced, permission and question events keep their existing routing, and execution failures preserve an error stop and message. The installer follows OpenCode's
OPENCODE_CONFIG_HOME/XDG_CONFIG_HOMEresolution, fixing the config-path mismatch from #15657.The regression coverage drives the generated plugin and V2 TUI bridge through duplicate updates, both idle shapes, completion, nested
session.error, and failure-first ordering. It also verifies XDG installation and Swift Feedis_errorpropagation. The cmux-tui core tests cover current completion and failure event classification.Related upstream work:
