## Thinking Path
> - Paperclip is the open source app that people use to manage AI agents
for work.
> - The runner E2E system verifies agent profiles across supported
execution environments.
> - Its generated report is the main surface for inspecting those
results and their visual evidence.
> - Expanded matcher content could change the matrix column widths and
make comparisons difficult.
> - Screenshots also required extra navigation, and the report did not
have current-result search and filters.
> - This pull request stabilizes the matrix layout and makes visual
evidence directly browsable.
> - The benefit is faster inspection of retained test evidence without
another paid matrix run.
## Linked Issues or Issue Description
**What happened?**
The runner E2E report changed matrix column widths when a matcher table
expanded. The report also made screenshot comparison and current-result
discovery slower than necessary.
**Expected behavior**
The matrix columns must remain stable. Each retained screenshot must
appear as a thumbnail. The gallery must support keyboard navigation and
show the relevant execution metadata. The report must support
client-side search and filters.
**Steps to reproduce**
1. Open a runner E2E matrix report that contains retained screenshots.
2. Expand the matcher details in a matrix cell.
3. Observe the matrix column movement in the old report.
**Paperclip version or commit**
`8430bd897`
**Deployment mode**
Generated static runner E2E report.
## What Changed
- Keep matrix and matcher table widths stable when details expand.
- Show retained screenshot thumbnails in each test card.
- Add a full-screen evidence gallery with mouse, keyboard, and swipe
navigation.
- Show agent, environment, runtime, status, duration, token, and matcher
data in the gallery header.
- Add client-side search and profile, environment, suite, and status
filters below the report section tabs.
- Keep the filters in normal document flow while the report tabs remain
sticky.
- Add report generator assertions for the new layout and controls.
- Add Playwright coverage for filtering, stable matcher expansion, and
filtered gallery navigation.
## Verification
- `pnpm test:e2e:runner:typecheck`
- `pnpm exec vitest run --config tests/runner-e2e/vitest.config.ts
tests/runner-e2e/report.test.ts`
- `PAPERCLIP_PLAYWRIGHT_CHANNEL=chrome pnpm exec playwright test
--config tests/e2e/playwright.config.ts
tests/e2e/runner-e2e-dashboard.spec.ts`
- `node --test ./scripts/__tests__/e2e-shard.test.mjs`
- `pnpm check:token-gates`
- `pnpm -r typecheck`
- `pnpm test:run`
- `pnpm build`
- Regenerated the report from GitHub Actions run `33963318820` without
rerunning the matrix.
- Verified 121 retained thumbnails across 66 results in a local browser.
- Verified that expanded matchers keep matrix widths at 260, 486, and
486 pixels in a 1280-pixel viewport.
- Verified search, filters, modal metadata, and arrow-key gallery
navigation.
## Risks
Low risk. This change only modifies the static runner E2E report
generator and its tests. It does not change runner execution or retained
evidence data.
> This work is focused report polish. It does not duplicate planned core
work in `ROADMAP.md`.
## Model Used
OpenAI Codex with `gpt-5.6-sol`. Codex desktop managed the context
window. The model used reasoning, filesystem tools, code execution,
GitHub CLI access, and in-app browser verification.
