Heya, I started using T3 code 2 days ago with the Openchud integration and I was quite surprised at it not working at all. I've forked T3 code to fix a lot of issues and I'm using the local build for now, but this change would make OpenCode adapter from currently unusable to slightly above usable.

What Changed

  • use/global/event from Opencood for runtime event ingestion and filter wrapped events by session directory
  • ignore malformed global event payloads before provider event projection
  • fall back to legacy /event subscription when global events are unavailable (a lot of chaps within the issue thread below downgraded to <=0.14.40, so this fix would make it work for older sessions too)

Why

Fixes #2644

UI Changes

  • [sí] I explained what changed and why
  • [oui oui] I included before/after screenshots for any UI changes

Note

Medium Risk
Changes OpenCode session event ingestion to prefer a new global event stream and adds fallback logic, which can affect turn completion and session lifecycle behavior if event formats or error detection differ across OpenCode versions.

Overview
Switches the OpenCode adapter’s event pump to prefer global.event (wrapped events) and projects provider runtime events only after filtering by session directory and validating the wrapped payload shape.

Adds compatibility fallback: if global.event is unavailable (e.g. 404 / TypeError), the adapter falls back to event.subscribe (now called with { directory }). Updates tests to cover global ingestion, directory filtering, malformed payload handling, and the fallback path.

Note

Fix hanging "waiting..." state in OpenCode adapter by preferring global.event stream over legacy event.subscribe

  • The event pump in OpenCodeAdapter.ts now first attempts to stream events from a global.event endpoint, filtering by context.directory to ignore events from other sessions and skipping malformed payloads.
  • Falls back to the legacy event.subscribe path (passing { directory } as a parameter) when global.event returns a 404 or a TypeError indicating the method is absent.
  • Both paths use a session-scoped AbortController that is cancelled on scope close.
  • Test coverage in OpenCodeAdapter.test.ts adds four new cases covering global events, directory filtering, malformed payload tolerance, and legacy fallback.

This PR might seem like a duplicate of #2673, and it kind of is, but 2673 removes the old event stream which would break and regress T3 code experience for users on Opencode versions that are lesser than <=0.14.40 (which relatively recent)

Approvability

Verdict: Needs human review

This PR modifies runtime event ingestion behavior by introducing a new global event API with fallback to legacy subscription. While well-tested with comprehensive coverage, changes to event processing pipelines that affect session state tracking warrant human review.

I'll hold off on updating the base branch as mr the O hates rebasing. If this is planned to be merged and the change looks good, do tag me and i'll update that asap

Assessed PR pingdotgg#2704 from pingdotgg/t3code which fixes OpenCode adapter
event ingestion for CLI versions >= 1.14.40.

The PR switches from legacy event.subscribe() to global.event endpoint,
adding directory filtering and payload validation. The root cause: newer
OpenCode versions wrap events in {directory, payload} envelopes, but
handleSubscribedEvent reads event.properties directly, silently
discarding all events. This causes the "working..." hang (pingdotgg#2644),
blank chat (pingdotgg#2652), and frozen sessions (pingdotgg#2691).

Verdict: Apply. Low merge risk — additive changes to OpenCodeAdapter.ts
with graceful fallback for SDKs < 1.4.7. All three issues share the
same root cause and are addressed.

Verified via git merge-tree: zero conflicts between upstream PR pingdotgg#2704
and fork HEAD. Both files diverge from merge base but changes land in
non-overlapping regions — fork's Crypto.randomUUIDv4 refactor and
buildEventBase rewrite don't touch the PR's new types, helpers, or
startEventPump regions.

…e (t3-29f.9)

Cherry-picked from upstream PR pingdotgg#2704 (bd4ac1a) by eersnington.

Fixes OpenCode event ingestion for CLI >= 1.14.40 where events are
wrapped in a { directory, payload } envelope via /global/event. The
legacy event.subscribe path returned raw events that the adapter's
handleSubscribedEvent couldn't unwrap, causing ALL events to be
silently discarded — sessions hung in "working..." indefinitely.

Changes:
- Prefer global.event endpoint with directory filtering to prevent
  cross-session event contamination
- Add parseOpenCodeSubscribedEvent() runtime validation to squelch
  malformed payloads instead of crashing the event pump
- Fall back to legacy event.subscribe({ directory }) when global.event
  is unavailable (404 or TypeError)
- Both paths use a session-scoped AbortController cancelled on scope close

Tests: 18/18 pass (4 new cases: global events, directory filtering,
malformed payload tolerance, legacy fallback).

Fixes issues pingdotgg#2644, pingdotgg#2652, pingdotgg#2691 (all share the same root cause).
