# OpenCode: what to test tonight

Every OpenCode turn now runs through the serve (`serve-runner.ts`). The `opencode run` subprocess is
deleted, so this is not a comparison against a fallback — it is the only path.

I have driven each item in **Should already work** end to end through the real chat socket, with a
script rather than a browser. Nothing below has been used by a person in a real conversation, and the
things in **Unproven** are unproven because probes cannot answer them.

---

## Before you start

```bash
cd ~/projects/officer-suite/platform
pm2 logs officer-opencode --lines 40      # the sidecar's own account of what happened
```

On boot you should see three lines: `serve healthy on port …`, `connected the opencode credential to the
api surface`, and the sidecar registering. **If the credential line is missing or says it could not
connect, stop** — paid models will silently do nothing, which is the failure that cost most of an
afternoon (`docs/opencode-fork-decision.md`).

Rolling back is `git revert` of `a3dbda7` (Phase D) and a restart. There is no config flag any more.

Alpha is unaffected until you pull.

## Should already work — confirm, do not investigate

Each verified by me end to end. If one fails, that is new information and worth stopping on.

- [ ] **A plain turn.** Ask for something short. Text arrives.
- [ ] **Streaming.** Ask for something long — "count slowly to 50". Text should appear **progressively**,
      not in one block at the end. This is the headline change; the old path could not do it.
- [ ] **A tool call.** "Run `echo hi` with bash." A tool row appears with the command as its arguments,
      then its output.
- [ ] **Cost.** The turn ends with a token count attached.
- [ ] **An image.** Drop a screenshot in and ask what it shows. It must actually be described — the
      failure mode is a confident answer about nothing, which is what B4 was.
- [ ] **Stop.** Press stop mid-turn. The turn ends **and the conversation stays usable** — send another
      message straight after and it should answer. Previously stop destroyed the session.
- [ ] **Mid-turn injection.** While a turn runs, send another message. It should join the RUNNING turn
      rather than starting a new one or superseding it.

## Unproven — this is the actual testing

- [ ] **Resume from history.** Open an older OpenCode conversation from the list and continue it. This
      exercises `resumeSessionId`, which I never tested against the serve. **Most likely thing to be
      broken.**
- [ ] **An idle session, an hour later.** Send a message to a conversation you have not touched for a
      while. Warm sessions are new here — the subprocess had nothing to go stale.
- [ ] **A sidecar restart mid-turn.** `pm2 restart officer-opencode` while a turn is generating. Expect
      the transcript to say the turn stopped. **The turn itself keeps running inside the serve** — that
      is intended, not a bug, but nobody has watched what it looks like from the browser.
- [ ] **An officer restart mid-turn.** Different from the above: officer is the relay, the sidecar keeps
      committing to `chat_session_events`. On reload the transcript should be intact. This is the one I
      would least like to be wrong about.
- [ ] **Two conversations at once.** The live event stream is GLOBAL — one socket carries every session
      and `serve-runner` filters on `sessionID`. If that filter is wrong, output from one conversation
      appears in another. Two panels side by side is the test.
- [ ] **The Live panel.** A running OpenCode turn should appear, named, and disappear when it ends.
- [ ] **A long turn.** Ten-plus minutes. The old path had watchdogs (inactivity, hard cap) that are gone
      with it; the serve has its own ideas about timeouts and I have not found their edges.
- [ ] **A failing tool.** Ask it to run a command that does not exist. The error should land in the
      transcript as a failed tool, not as a dead turn.

## Known gaps, so you do not report them as bugs

- **No durable replay.** `serve-runner` reads the live stream only. Events are still committed to
  `chat_session_events` as they arrive, so the transcript survives — but recovering a turn *this sidecar
  process never saw* would need the `?after=` cursor, and that is not built.
- **Notifications/thinking/background tasks.** Not implemented on this harness. Thinking is deliberately
  out of scope for both harnesses.
- **`messageCount` shows nothing** for OpenCode rows. The UI renders an `OpenCode` badge instead; not a
  gap (`docs/opencode-parity.md`).

## What is useful to tell me

For anything that misbehaves: what you did, what appeared, and the last twenty lines of
`pm2 logs officer-opencode`. The sidecar logs its own errors, and a silent failure with clean logs is a
different diagnosis from a loud one.

If a turn produces **nothing at all** — no text, no error, no spinner ending — check the credential line
from boot first. That specific silence has one cause and I have chased it twice.
