Summary

• Remove low-value copy, SEO metadata, and duplicate assertions while preserving behavior and correctness checks.
• Update testing guidance to prioritize expected behavior and critical correctness over coverage counts.
• Add change-aware PR test planning and keep full-suite verification for releases.
• Fix the installer CLI e2e script to ignore an inherited SUBSHELL_DATA_DIR when it creates an isolated fake home.

Verification

• Unit tests: 12,543 passed, 5 skipped.
• Script tests: 335 passed, 3 skipped.
• Build, type checks, lint, and Rust fmt/Clippy/tests passed.
• Playwright e2e after fixture fixes: 87 passed, 5 skipped, 0 failed.
• Compiled CLI integration, including installer and server/node update scenarios, passed on the clean CI runner.

CI follow-up fixes prepare website data before type checking, build the SPA before server tests, isolate server test files, and validate the update backup archive instead of obsolete console text. Workflow-planning tests: 18 passed. All checks passed on commit 5f15feb, including browser/CLI integration, all unit lanes, build/types/lint, Linux/macOS Rust, and CodeQL. Browser tests now identify their launched pane from its actual WebSocket connection to avoid workspace navigation and pane-order races.
