## Thinking Path
> - Paperclip orchestrates AI agents through a company-scoped control
plane.
> - The affected surface is the board UI for issue threads, issue lists,
routines, dialogs, navigation, and issue review indicators.
> - Closed PR #4692 bundled backend, schema, docs, workflow, and UI/QoL
work into one oversized change set.
> - Greptile could not keep reviewing that broad PR because it exceeded
the 100-file review limit and mixed unrelated concerns.
> - This pull request extracts the UI/QoL slice into a fresh branch
under the review limit while leaving workflow and lockfile churn out.
> - The benefit is a focused review path for the board UI performance
and workflow improvements without reopening the oversized PR.
## What Changed
- Added long issue-thread virtualization, scroll-container binding,
anchor preservation, latest-comment jump targeting, and related
regression/perf fixtures.
- Improved issue list scalability with scroll-based loading, server
offset parameters, and pagination-focused UI tests.
- Reduced new issue dialog typing churn and split dialog action
subscriptions so broad layout/nav surfaces avoid unnecessary renders.
- Added routine variables help and routine description mention options
for users, agents, and projects.
- Added productivity review badge/link UI and fixed the badge to use
Paperclip's company-prefixed router link.
- Kept the split PR below Greptile's review limit and excluded
`.github/workflows/pr.yml` and `pnpm-lock.yaml`.
## Verification
- `pnpm install --no-frozen-lockfile` in the clean worktree to install
`@tanstack/react-virtual` locally without committing lockfile churn.
- `pnpm --filter @paperclipai/ui exec vitest run --config
vitest.config.ts src/components/IssueChatThread.test.tsx
src/components/IssuesList.test.tsx
src/components/NewIssueDialog.test.tsx src/pages/Routines.test.tsx
src/pages/Issues.test.tsx` passed: 5 files, 83 tests.
- `pnpm --filter @paperclipai/ui typecheck` passed.
- `git diff --check origin/master..HEAD` passed.
- Split-scope checks: 53 changed files; no `.github/workflows/pr.yml`;
no `pnpm-lock.yaml`.
- Screenshots were not captured in this heartbeat; the changes are
primarily virtualization, routing, pagination, and editor behavior
covered by focused regression tests.
## Risks
- Moderate UI risk because issue-thread virtualization changes scroll
behavior on long conversations; regression tests cover anchor jumps,
latest-comment targeting, row metadata, and short-thread fallback.
- Moderate integration risk because the issue-list offset parameter and
productivity review field depend on matching API behavior.
- Dependency risk: the UI package adds `@tanstack/react-virtual` while
repository policy keeps `pnpm-lock.yaml` out of PRs, so CI must resolve
dependency changes through the repo's normal lockfile policy.
> 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, GPT-5 coding agent, tool-enabled local repository and
GitHub workflow. Exact runtime context window was not exposed by the
harness.
