DottaandClaude Opus 5.5 4e519bd428 fix(chat): send writes with an empty responseText and point card declines to resolve-from-comment (#21050)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Chat agents call the Paperclip API through `call_api` and find
routes with `search_api`
> - #21035 added a pre-send refusal for writes that carry
`responseText`, and new summaries for the question cancel and withdraw
routes
> - Full chat cohort 5 (OpenCode with DeepSeek v4.1 flash) showed that
both changes went too far
> - The refusal blocked a valid write that had an empty `responseText`,
and the summaries hid the route that records a person's decline
> - This pull request narrows the refusal and corrects the guidance text
> - The benefit is that valid writes go through on the first try, and
agents settle a declined card instead of leaving it pending

## Linked Issues or Issue Description

Refs #21035, #21002

**What happened?**
- inbox-search.restore-archive: DeepSeek sent `responseText: {}` with a
valid body on `POST /api/issues/{id}/inbox-archive`. The refusal from
#21035 rejected 24 POSTs in 3 minutes. The model did not drop the key,
and the run was cancelled at the 240s window. In cohort 4 the same POSTs
went through on the first try.
- questions-and-approvals.reject-and-revise: the person said "Do not
publish it; just make a draft I can review." The CEO quoted the cancel
summary ("an agent withdraws its own pending card with POST
.../withdraw"), saw that the person created the publish card, and left
the card pending. The plan decision did not settle. In cohorts 3 and 4
the CEO declined the card with `resolve-from-comment` (resolver policy
`anyone`).

**Expected behavior**
- A write with an empty or default `responseText` is sent once. A write
whose `responseText` sets a window is still refused before it is sent.
- The guidance says that withdraw is only for the agent's own obsolete
card, and that a person's explicit decline or answer goes through
`resolve-from-comment` when the card's resolver policy allows.

**Steps to reproduce**
Run the two chat cases above with OpenCode and DeepSeek v4.1 flash on
master.

## What Changed

- `call_api` (`assertRunnerApiDispatchable`): the check reads the raw
`responseText` value. `{}` or `{ offsetBytes: 0 }` on a write is dropped
and the write is sent. A `responseText` with `limitBytes` or a later
offset is still refused. `saveResponse: false` on a write was already
accepted; a test now covers it.
- OpenAPI: the cancel and withdraw summaries say that withdraw is only
for the agent's own obsolete card, and that a decline or answer on the
person's explicit instruction uses `POST .../resolve-from-comment` when
the resolver policy allows. The `resolve-from-comment` summary says it
also records a decline of a card the person created.
- `AGENT_CHAT_DIRECTIVE`: a person's explicit decline in chat answers a
pending confirmation with reject, whoever created the card. Withdraw
never records the person's decision.
- `doc/runner-api-tools.md`: describes the narrowed refusal.

## Verification

- `server/src/services/native-runtime/runner-api.test.ts`: new test
sends `POST /api/issues/{id}/inbox-archive` with a valid body and
`responseText: {}`, `{ offsetBytes: 0 }`, `saveResponse: false`, or
both. The request is sent exactly once. Red before the fix (3 of 4 cases
refused), green after. The refusal test for a `responseText` with
`limitBytes` stays.
- `server/src/__tests__/openapi-routes.test.ts`: new test for the
cancel, withdraw and resolve-from-comment summaries. Red before, green
after.
- `server/src/__tests__/agent-conversations.test.ts`: new directive test
for the decline rule. Red before, green after.
- Also passed: `runner-api.integration.test.ts`,
`native-case-tools.integration.test.ts`, server `tsc --noEmit`. SDK
public input pins: `--check` reports no change.
- Paid run (OpenCode + DeepSeek v4.1 flash) on this branch for
inbox-search.restore-archive, questions-and-approvals.reject-and-revise,
gateways-profiles.rotate-token and budgets-costs.repair-cost-recording:
4 of 4 cells passed on 3f20fb2bcc (run 43177772183); details in a PR
comment.

## Risks

- A write with a populated `responseText` is still refused, as in
#21035. Only the empty and default shapes change. A dropped empty
`responseText` changes nothing, because the server already removed it
from writes before sending.
- The directive grows by two sentences, which adds a small number of
prompt tokens per chat turn.

## Model Used

- Anthropic Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with
tool use, shell execution and code editing.
