## Thinking Path

> - Paperclip helps operators supervise agent work through tasks and
task threads.
> - The redesigned task thread shows the current work and its state.
> - A blocked task did not show the dependency that prevented progress.
> - Operators had to leave the thread to find the direct and final
blockers.
> - This pull request adds compact blocker links at the top and bottom
of the task thread.
> - The benefit is that operators can identify and open the relevant
tasks without adding a large notice to the thread.

## Linked Issues or Issue Description

**What existing behavior does this improve?**

The redesigned task thread did not show which task directly blocked the
current task or which task ultimately blocked its dependency chain.

**Subsystem affected**

`server/`, `packages/shared/`, and `ui/` task-blocker presentation.

**Current behavior**

A blocked task can open in the redesigned thread without a visible
dependency link at the top or bottom of the conversation.

**Proposed behavior**

Show one compact amber row for the direct blocker. Show a second row for
the selected final blocker when one exists. Render the rows at both ends
of the thread.

**Reason and benefit**

Operators can see the reason for the blocked state and open the relevant
task from the conversation. The compact rows preserve thread density.

**Breaking changes**

None. The new blocker-attention fields are optional. Existing clients
remain compatible.

## What Changed

- Added a compact task-chat component for direct and selected final
blocker links.
- Added the blocker rows to the top and bottom of populated and empty
task threads.
- Added link-ready blocker-attention details so an intermediate selected
task stays on its correct direct chain.
- Included blocker-link changes in the thread content key so pinned
threads follow a newly added bottom row.
- Added component, scrolling, server contract, and Storybook coverage
for the new states.

## Verification

- `pnpm exec vitest run ui/src/components/TaskChatThread.test.tsx
server/src/__tests__/issue-blocker-attention.test.ts` (38 tests passed)
- `pnpm --filter @paperclipai/shared typecheck`
- `pnpm --filter @paperclipai/server typecheck`
- `pnpm --filter @paperclipai/ui typecheck`
- `pnpm check:token-gates`

## Risks

- Low risk. The rows only render while the task status is `blocked` and
an unresolved blocker is available.
- Long titles are truncated to keep each blocker on one line. The full
task label remains available in the link title.
- Older server payloads keep the original leaf-selection behavior
because the new sampled details are optional.

> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected — check the roadmap
first. See `CONTRIBUTING.md`.

## Model Used

- OpenAI Codex with GPT-5. The run used tool-enabled reasoning and code
execution. The context-window size was not exposed to the run.
