## Summary
Adds browser DOM repair suggestions inside `services/computer-use-mcp`.
Known browser DOM action failures now get structured, advisory-only
repair suggestions for selector misses, hidden elements, timeouts,
detached frames, and stale elements. The registration path uses the
suggestions for `browser_dom_click` and `browser_dom_wait_for_element`
thrown-error responses.
## Boundary
- Only touches `services/computer-use-mcp`.
- Does not touch app, renderer, overlay, extension assets, desktop v3
files, or root project governance files.
- Does not import preview changes that delete current upstream
Chrome/desktop files.
- Does not include local AI config, screenshots, tokens, account
identifiers, or raw environment dumps.
## Validation
Sanitized evidence is committed in
`services/computer-use-mcp/validation/browser-repair-contract.md`.
Ran:
- `pnpm install --ignore-scripts --frozen-lockfile`
- `pnpm -F @proj-airi/computer-use-mcp exec vitest run
src/browser-dom/browser-repair-contract.test.ts
src/server/register-tools-pty-approval.test.ts --config
./vitest.config.ts`
- `pnpm exec moeru-lint --fix
services/computer-use-mcp/validation/browser-repair-contract.md
services/computer-use-mcp/src/browser-dom/browser-repair-contract.ts
services/computer-use-mcp/src/browser-dom/browser-repair-contract.test.ts
services/computer-use-mcp/src/server/register-tools.ts
services/computer-use-mcp/src/server/register-tools-pty-approval.test.ts`
- `git diff --check`
`pnpm -F @proj-airi/computer-use-mcp typecheck` is currently blocked by
existing baseline errors in `chrome-session-manager` and
`desktop-grounding`, outside this patch. The validation note lists the
error classes without local paths or raw logs.
