## Thinking Path
> - Paperclip's board UI and bundled skills are the operator layer for
configuring agents, routines, issue workflows, and local troubleshooting
loops.
> - The prior rollup mixed this operator polish with database backups,
backend reliability, thread scale, and cost/workflow primitives.
> - This pull request isolates the remaining board QoL, settings,
issue-detail integration, adapter config cleanup, and skills smoke
tooling.
> - It includes some integration-level overlap with the thread and
workflow slices so this branch can run from `origin/master` while still
preserving the full original work.
> - Preferred merge order is the narrower primitives first, then this
integration PR last.
> - The benefit is that reviewers can inspect the user-facing
board/settings/skills layer separately from backend infrastructure
changes.
## What Changed
- Added board/settings polish for agents, routines, company settings,
project workspace detail, and issue detail controls.
- Added agent/routine UI regression tests and New Issue dialog coverage.
- Integrated issue-detail activity/cost/interaction surfaces and leaf
work pause/resume controls.
- Cleaned bundled adapter UI config defaults and onboarding copy.
- Added terminal-bench loop and work-stoppage diagnosis skills plus a
smoke test script.
- Updated attachment type handling and Paperclip skill/API guidance.
## Verification
- `pnpm install --frozen-lockfile`
- `pnpm exec vitest run ui/src/pages/Agents.test.tsx
ui/src/pages/Routines.test.tsx ui/src/components/NewIssueDialog.test.tsx
ui/src/pages/IssueDetail.test.tsx
server/src/__tests__/costs-service.test.ts
server/src/__tests__/issue-thread-interaction-routes.test.ts
server/src/__tests__/issue-thread-interactions-service.test.ts`
- Result: 7 test files passed, 54 tests passed.
- `pnpm run smoke:terminal-bench-loop-skill`
- Result: JSON output included `"ok": true` and `"cleanup": true`.
- UI screenshots not included because verification is focused
component/page coverage for the changed board surfaces.
## Risks
- This is the integration-heavy PR in the split and intentionally
overlaps some component/API primitives with the issue-thread and
workflow PRs so it can run from `origin/master`.
- Preferred merge order: #4859, #4860, #4861, #4862, then this PR last.
If earlier branches merge first, this PR may need a straightforward
conflict refresh in shared UI files.
- The terminal-bench smoke script creates temporary mock issues and
relies on cleanup; the verified run returned `cleanup: true`.

## Model Used
- OpenAI Codex, GPT-5.5, code execution and GitHub CLI tool use, medium
reasoning effort.

## Thinking Path
> - Paperclip is the control plane for autonomous AI companies, so
backend task ownership, recovery, review visibility, and company-scoped
limits need to stay enforceable without UI-only coupling.
> - Closed PR #4692 bundled those backend changes with UI workflow,
docs, skills, workflow, and lockfile churn.
> - PAP-2694 asks for a clean backend/control-plane slice from that
closed branch.
> - This branch starts from current `master` and mines only the `cli`,
`packages/db`, `packages/shared`, and `server` contracts/tests needed
for the backend behavior.
> - It explicitly excludes UI workflow/performance work,
`.github/workflows/pr.yml`, `pnpm-lock.yaml`, docs, skills,
package-script, adapter UI build-config, and perf fixture script
changes; the only UI files are fixture/test updates required by the
tightened shared `Company` contract.
> - The benefit is a smaller reviewable PR that preserves the
control-plane fixes while staying under Greptile s 100-file review
limit.
## What Changed
- Added company-scoped attachment-size limits through DB
schema/migrations, shared company portability contracts, CLI
import/export coverage, and server attachment upload enforcement.
- Added productivity review service/API behavior for no-comment streak,
long-active, and high-churn review issues, including request-depth
clamping and issue summary exposure.
- Hardened issue ownership and recovery/control-plane paths: peer-agent
mutation denial, issue tree pause/resume behavior, stranded recovery
origins, and related activity/test coverage.
- Preserved related backend contract updates for routine timestamp
variables and managed agent instruction bundles because they live in
shared/server contracts from the source branch.
- Addressed Greptile feedback by making `Company.attachmentMaxBytes`
non-optional, simplifying review request-depth clamping, fixing the
migration final newline, and enforcing the process-level attachment cap
as the final ceiling for uploads.
- Added minimal company fixtures needed for repo-wide typecheck/build
and kept the PR to 66 changed files with forbidden/non-slice paths
excluded.

## Risks
- Includes migrations `0073_shiny_salo.sql` and
`0074_striped_genesis.sql`; merge ordering matters if another PR adds
migrations first.
- This is intentionally backend-only apart from fixture/test updates
forced by shared type correctness; UI affordances from PR #4692 are not
present here and should land in separate UI slices.
- The worktree install emitted plugin SDK bin-link warnings for unbuilt
plugin packages, but the targeted tests and package typechecks completed
successfully.

Add PAPERCLIP_ALLOWED_ATTACHMENT_TYPES env var to configure allowed
MIME types for issue attachments and asset uploads. Supports exact
types (application/pdf) and wildcard patterns (image/*, text/*).
Falls back to the existing image-only defaults when the env var is
unset, preserving backward compatibility.
- Extract shared module `attachment-types.ts` with `isAllowedContentType()`
and `matchesContentType()` (pure, testable)
- Update `routes/issues.ts` and `routes/assets.ts` to use shared module
- Add unit tests for parsing and wildcard matching
Closes#487
