DottaandClaude Opus 5.5 d10c6e0e8b fix(chat): hold a chat message at the agent's daily limit instead of dropping it (#20292)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent Chat sends each person's message to the conversation agent
through a durable outbox (`deliverConversationComments`). The outbox
keys each wake receipt as `conversation-comment:<commentId>`.
> - The outbox treats any receipt with that key as delivered. Queue
admission writes a `skipped` receipt when the agent reached its daily
run or cost limit.
> - So a chat message sent after the agent used its daily allowance was
consumed silently. No run started, the chat showed nothing, and nothing
resumed it.
> - A person's message must never be silently dropped. The daily limit
is an operator control, so the message must wait honestly, not bypass
the limit.
> - This pull request makes the outbox hold the message at the daily
limit, like it already does for a paused agent, and resume it when the
limit resets.
> - The benefit is that a chat message at the daily limit is saved,
shown with its reason, and sent automatically at 00:00 UTC.

## Linked Issues or Issue Description

No public issue exists. Inline bug report:

**What happened**

In a chat eval, the conversation agent (CEO) had `maxDailyRuns: 3`.
After three chat turns and a separate failed-model phase on another
agent, the person sent a fourth message. The comment was saved (POST
201), but no CEO run started. The conversation stayed `active` with no
`executionRunId`. The ownership reconciler later reported
`I7_visible_next_action`. The server log shows no wake error. Queue
admission had written a `skipped` receipt (`heartbeat.daily_run_limit`)
under the outbox key, so the outbox counted the message as delivered.

**Expected behavior**

A chat message that reaches the agent's daily limit is not consumed. It
stays saved, the chat shows why it waits, and it is sent automatically
when the limit resets. The daily limit still applies: the message does
not start a run early.

**Steps to reproduce**

1. Set a conversation agent's `runtimeConfig.heartbeat.maxDailyRuns` to
N.
2. Send N chat messages and let each turn finish.
3. Send one more chat message.
4. See that no run starts, the chat shows no waiting state, and the
message is never answered (a `skipped` wake receipt with reason
`heartbeat.daily_run_limit` exists for `conversation-comment:<id>`).

## What Changed

- `server/src/services/agent-conversations.ts`: add
`conversationDeliveryHold`, which applies the same daily run/cost limit
check as queue admission. The outbox returns `deferred` at the limit and
writes no receipt, so the message stays owed. It reports the next UTC
day start through a new optional `onDeferredDeadline` option.
- `server/src/services/recovery/service.ts`: stranded-work recovery
passes its `onDeferredDeadline` to the outbox, so the held message is
retried when the limit resets.
- `server/src/services/heartbeat/queue.ts`: if the limit is reached
while an outbox wake is in admission (a race), admission throws a 409
with `reason: heartbeat.daily_*` for `conversation-comment:` keys
instead of writing a `skipped` receipt. The outbox already maps a
matching 409 to `deferred`. Other wakes keep the current skip behavior.
- `server/src/routes/issues.ts` (`GET /issues/:id/queued-comments`):
when a chat has no queue receipt but has messages held by the daily
limit, return them as a `deferred` queue with `executionWait` (reason
and message). Edit, send and discard stay off because the outbox owns
delivery.
- `ui/src/components/task-chat/TaskChatQueuedMessages.tsx`: show the
`executionWait` message for such an outbox-held queue (no queue id and
no target run). Receipt-backed queues keep the current behavior and do
not duplicate the task status.
- Tests: three real-database tests in
`agent-conversation-delivery.test.ts` (hold and resume after the limit
resets, recovery deadline, and a limit reached during real
`heartbeatService.wakeup` admission) and one UI test.

## Verification

- `cd server && pnpm exec vitest run
src/__tests__/agent-conversation-delivery.test.ts`: 10 passed. Without
the source change, the three new tests fail (`expected 'delivered' to be
'deferred'`; the real queue path writes the skipped receipt).
- `cd server && pnpm exec vitest run
src/__tests__/issue-recovery-conversations.test.ts
src/__tests__/agent-conversations.test.ts
src/__tests__/heartbeat-undispatched-execution-wait.test.ts
src/services/heartbeat/queue.test.ts
src/__tests__/agent-chat-messages.test.ts`: 215 passed.
- `cd ui && pnpm exec vitest run
src/components/task-chat/TaskChatQueuedMessages.test.tsx`: 36 passed.
- `pnpm exec tsc --noEmit -p server/tsconfig.json`: clean. `node
scripts/check-token-gates.mjs`: clean.
- Manual: give a chat agent `maxDailyRuns: 1`, send two messages. The
second message shows in the queued messages bar with "<agent> reached
its daily run limit. Your message is saved and sends automatically when
the limit resets at 00:00 UTC."

## Risks

- Behavior change for chat only: a chat message at the daily limit now
waits in the outbox instead of being consumed. It is sent after 00:00
UTC. If an operator raises the limit, the message is sent on the next
recovery pass for that chat; the UI message does not promise an earlier
send.
- Saved state from the previous release: no persisted shape changes.
Messages that an earlier release already consumed with a `skipped`
receipt stay consumed. They are not replayed later, which avoids sending
old messages without notice.
- The queued-comments read adds one agent read and one daily-limit count
for a chat with no queue receipt. This is the same query that admission
runs.
- The recovery deadline is in-process; instance-sleep scheduling does
not get a new deadline from this change.

## Model Used

- Anthropic Claude Opus 5.5 (`claude-opus-5-5`), agentic coding with
tool use (shell, file edits, test runs).

@paperclipai/ui

Published static assets for the Paperclip board UI.

What gets published

The npm package contains the production build under dist/. It does not ship the UI source tree or workspace-only dependencies.

Storybook

Storybook config, stories, and fixtures live under ui/storybook/.

pnpm --filter @paperclipai/ui storybook
pnpm --filter @paperclipai/ui build-storybook

Typical use

Install the package, then serve or copy the built files from node_modules/@paperclipai/ui/dist.

Editor dependency identity

Keep the root and workspace overrides for @codemirror/state, @codemirror/view, and @lezer/common aligned. CodeMirror requires shared extension identity, while Lezer parsers and syntax highlighters require shared NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with tags is not iterable. src/lib/codemirror-single-instance.test.ts checks the installed dependency graph and highlights sample code through the editor's real language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
