## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - The board UI is the main daily navigation surface for agents,
projects, and their related resources.
> - Operators need a lightweight way to keep frequently used agents and
projects close without changing company-wide ordering or ownership.
> - Resource memberships already model per-user relationships to
projects and agents, so they are the right place to store user-specific
starred state.
> - This pull request extends that membership contract with a starred
timestamp and exposes star controls in list/detail views.
> - The sidebar then uses those starred memberships to show compact,
user-specific shortcuts.
> - The benefit is faster navigation without introducing a separate
favorites system or leaking preferences across users.

Feature request:
## Problem or motivation
Users cannot pin frequently used agents or projects into the main
sidebar. Returning to important resources requires scanning full
project/agent lists or navigating through detail pages, which adds
friction to repeated daily workflows.
## Proposed solution
Store a per-user `starred_at` timestamp on agent and project
memberships, expose API actions to set or clear that state, add star
toggle controls to list/detail pages, and render starred projects and
agents as compact sidebar shortcuts.
## Alternatives considered
A separate favorites table would work, but it would duplicate membership
scoping and require another resource relationship model. Keeping starred
state on memberships preserves existing company/user boundaries and
avoids a second source of truth.
## Roadmap alignment
Checked `ROADMAP.md`; no overlapping planned core work for starred
resource/sidebar navigation was found.
## Additional context
The affected subsystems are `packages/db`, `packages/shared`, `server/`,
and `ui/`. The migration is idempotent with `IF NOT EXISTS` guards so
environments that saw an earlier local migration name can still apply
the final ordered migration safely.
## What Changed
- Added idempotent migration `0133_resource_membership_stars` for
`starred_at` columns and lookup indexes on agent/project memberships.
- Extended shared resource membership types and validators with starred
metadata and actions.
- Updated server resource membership services/routes to read and mutate
starred resource state.
- Added reusable star toggle UI and resource membership hook support for
starred state.
- Added starred projects and agents sidebar rendering, plus star
controls on list and detail pages.
- Added focused shared, server, and UI coverage for starred membership
behavior and sidebar rendering.
## Verification
- Rebased and force-with-lease pushed current PR head
`a086fc965391c9e50a51b5b83b5b44a797b2a6f4` onto current
`paperclipai/paperclip:master`; `gh pr view` reports `MERGEABLE` with no
merge conflicts. GitHub checks are green for this fresh head.
- `pnpm exec vitest run packages/shared/src/resource-memberships.test.ts

- Greptile re-review is 5/5; the remaining screenshot thread was
resolved as non-blocking because this task explicitly requested no
screenshots/images in the PR.
- `pnpm exec vitest run

mobile pending-spinner fix.

- `pnpm --filter @paperclipai/db typecheck && pnpm --filter

typecheck && pnpm --filter @paperclipai/ui typecheck` passed
db/shared/server, then failed in pre-existing UI code outside this PR:
`src/pages/CompanyEnvironments.tsx` missing `@xterm/*` type declarations
and `previous` possibly null.
- Checked that the PR diff does not include `pnpm-lock.yaml` or
`.github/workflows` changes.
- Checked `ROADMAP.md` and found no overlapping planned core work for
starred resource/sidebar navigation.
- Searched existing GitHub PRs for duplicate starred-resource/sidebar
work and found none.
## Risks
- Migration touches membership tables. The SQL uses `IF NOT EXISTS` for
columns and indexes so environments that saw an earlier local migration
name can still apply this safely.
- Sidebar ordering and visibility changes could affect users who rely on
the previous flat sidebar layout.
- Starred state is per-user membership metadata; code paths must
continue preserving company/user scoping around memberships.
