## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - People open tasks from their personal workspace and send replies to
agents.
> - Cold task opens should load recent conversation before older
history.
> - Classic settings could expand history before the Coordinator
preference arrived.
> - Coordinator lists also read full tasks, and response startup used
the previous assignee.
> - This pull request restores compact reads and keeps the selected
responder visible through runtime discovery.
> - People can read and reply without waiting for unrelated history or
losing response feedback.
## Linked Issues or Issue Description
Related: #17593, #17751, #17756, #17885, #17983, and #18092.
**What happened?**
A cold task could select Classic full history while its personal
workspace preference was pending. The full-history choice stayed cached
after Coordinator became active. Coordinator Tasks used full task reads.
Needs attention fetched one enriched task per pending task.
Sending to a newly selected agent could show no responder, show the
previous assignee, or clear feedback when assignment changed. Legacy
runtime discovery then replaced the startup identity with a generic
activity line.
**Expected behavior**
Wait for the workspace preference before selecting Classic history. Show
the task instruction and recent conversation with **More messages** for
older content. Read collection indexes and fetch diagnostics for visible
rows. Keep the selected responder mounted from Send through saved input
and runtime startup.
**Steps to reproduce**
1. Enable Classic task UI and Coordinator. Delay the personal workspace
preference on a cold task open.
2. Open Coordinator Tasks or its Needs attention view with many pending
tasks.
3. Open a task assigned to a person. Select another agent in the
composer and send a message.
4. Let the message save before runtime reads return. Then allow a legacy
run to appear.
## What Changed
- Wait for task interface settings before persisting Classic history
expansion.
- Use lightweight indexes for Coordinator Tasks. Resolve pending task
IDs in batches of at most 100. Keep search and participant filters on
the server. Enrich at most 50 visible rows through the existing hook
without replacing list membership or order.
- Preserve an error when a pending task cannot load, instead of showing
a false all-clear.
- Register board cards for row enrichment. Observe newly mounted cards
after column expansion or pagination, and track visibility by element so
hidden list rows cannot clear visible board cards with the same task ID.
- Track the recipient of each submitted message through reassignment. A
later draft's recipient does not change the response already starting.
- Share a stable response header across startup, native runtime, and
legacy runtime rendering. Keep the existing transcript renderers.
- Add regression tests, production-browser checks, design guidance, and
feature-map notes.
## Verification
- Red/green: delayed Coordinator preference started a full comments read
before the fix. It now retains compact history and still expands on
request.
- Red/green: sends from human or other-agent assignment showed no
identity or the wrong identity. Both now retain the selected responder
through assignment, acknowledgement, later draft selection, and
native/legacy startup.
- In a 105-task Needs attention fixture, the previous code made 105
enriched detail requests. The fixed code makes two bounded index
requests.
- All 659 final affected tests pass across task detail, thread, runner
turn, history window, Inbox, board, row enrichment, and Coordinator
collection suites.
- Review follow-up: the production board lost its next-step badge before
card registration. The regression now passes, along with column
pagination. The focused 82-test enrichment run and 371-test
header/thread run also pass.
- All 12 compact-startup browser checks pass against the production UI
and an isolated PostgreSQL container. They cover delayed preferences,
list navigation, saved-card geometry, document/comment anchors, history
expansion, draft retention, retry, and actual legacy process startup.
The final deterministic process case recorded 118 frames with zero
missing or replaced responder identities. It does not call a model
provider.
- Full workspace build and typecheck pass. Final UI build and typecheck
pass after the shared-header change. Token gates, map checks, module
boundaries, and diff checks pass.
- The full UI rerun before the board review follow-up passed all 10,034
tests across 844 files. The 659 affected tests pass after that
follow-up. The first full UI run passed 10,030 tests and timed out in
one unchanged IssuesList large-tree test. Its two variants pass in an
isolated rerun and in the full rerun. Those later passes establish
recovery; the earlier timeout's cause remains unproven.
- The full `pnpm test:run` attempt was stopped after repeated embedded
PostgreSQL initialization failures in server fixtures. No complete local
server-suite pass is claimed. Browser verification recovered with a
disposable container database.
- A later avatar browser rerun reused the previous same-title task and
its cancelled run through the existing 48-hour title deduplication. That
fixture never reached fresh runtime startup. The test now uses a unique
title and checks its initial assignment/status; a full 12-case rerun and
a second avatar run on the same instance pass. The failed trace is
retained locally.
- Final commit `7a18372da3` has 55 successful checks, two intentionally
skipped Storybook checks, and one neutral Paperclip Review. All required
verification gates are green. Greptile is 5/5 with no actionable
findings or open review threads. The advisory Paperclip review paused
without a complete assessment; no passing Paperclip assessment is
claimed.
- These checks establish bounded reads and stable rendering. No reliable
staging latency benchmark or staging deployment is claimed.
## Risks
- Collection projections omit task bodies. Detail navigation must retain
its normal core/full task reads. Search remains server-side.
- Startup feedback must end on rejection, unavailable agents, terminal
outcomes, or a visible run. Existing cases cover those transitions.
- The shared header changes the legacy live-turn layout to retain
identity beside its existing status line.
- No migration, mutation permission, provider protocol, or execution
authority change.
## Model Used
OpenAI Codex, GPT-6 family. The exact serving deployment ID and
context-window size are not exposed in this session. The model used
reasoning, code editing, shell tools, automated Chromium checks, and
manual browser inspection.
