opencode-codes 1.18.5

# Captured wire fixtures

Real HTTP/SSE payloads captured live from an **opencode 1.18.5** server
(`GET /doc` reported `1.18.5`) running unauthenticated at
`http://127.0.0.1:41999`. They are the type-level drift tripwire consumed by
`tests/deserialization_tests.rs`: every file must deserialize losslessly into
the generated `opencode_codes::protocol_generated::types` and re-serialize to a
subset of its original wire JSON.

Do not hand-edit these files. To refresh them, re-run the captures below against
a live server and re-run the deserialization suite.

## Provenance

Captured 2026-07-26 by driving the six hand-wrapped endpoints with `curl`. The
server had a working mock provider (`providerID: "opencode"`, model
`big-pickle`), so assistant turns carry real reasoning/text/step parts rather
than a provider error. Session/message/permission ids are from that live run.

## Contents

### `rest/` — REST request/response bodies

| File | Endpoint | Type it deserializes into |
|------|----------|---------------------------|
| `session_create.json` | `POST /session` (200) | `Session` |
| `session_status_empty.json` | `GET /session/status` (200, idle) | `BTreeMap<String, SessionStatus>` |
| `session_status_busy.json` | `GET /session/status` (200, mid-prompt) | `BTreeMap<String, SessionStatus>` |
| `messages_empty.json` | `GET /session/{id}/message` (200, fresh session) | `Vec<MessageWithParts>` |
| `messages_after_prompt.json` | `GET /session/{id}/message` (200, after a prompt) | `Vec<MessageWithParts>` |
| `abort_response.json` | `POST /session/{id}/abort` (200) | `bool` |

`POST /session/{id}/prompt_async` is not represented by a response body: it
answers **HTTP 204 No Content**. Its effect is observed in
`messages_after_prompt.json` and the event stream.

### `events/` — `GET /event` Server-Sent Events

`event_stream.jsonl` is one captured SSE `data:` payload per line (the frames
observed while a prompt was submitted on a second session). Each line
deserializes into the internally-tagged `Event` enum. Per-type pretty-printed
samples (`type_*.json`) are the first occurrence of each distinct event type,
kept for readable inspection. Types exercised: `server.connected`,
`session.updated`, `message.updated`, `message.part.updated`,
`message.part.delta`, `session.status`, `session.diff`, `session.idle`.

### `errors/` — error responses

| File | How produced | Type |
|------|--------------|------|
| `session_not_found.json` | any per-session call with an unknown session id (404) | `NotFoundError` |

sleep 4
curl -s "$BASE/session/$SID/message" > rest/messages_after_prompt.json
curl -s -X POST "$BASE/session/$SID/abort" > rest/abort_response.json   # -> true
