Code Review

This pull request introduces significant repository hygiene, governance, and architectural updates to OmniRoute, notably integrating maximhq/bifrost as a Tier-1 router layer (ADR-031), adding an Electrobun-based desktop application spike, and standardizing CI/CD, pre-commit/pre-push hooks, and project tracking. Review feedback identifies a critical path resolution bug in the ADR quality lint script (.githooks/adr-quality-lint.py) that causes it to silently skip execution, along with style guide violations regarding the placement of CODEOWNERS and .gitleaks-push.sh in the project root. Additionally, a compatibility improvement is suggested for the pre-commit hook fallback path to handle environments where bun is not installed.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

There is a path resolution bug here. Since this script is located in .githooks/adr-quality-lint.py, resolving .parent.parent.parent goes three levels up, which points to the directory above the repository root. This causes adr_dir to point to a non-existent path, making the linter silently skip execution by returning 0 on line 21. It should only go two levels up to reach the repository root.

Suggested change

	root = Path(__file__).resolve().parent.parent.parent
	adr_dir = root / "docs/adr"
	root = Path(__file__).resolve().parent.parent
	adr_dir = root / "docs/adr"

The fallback checks use bun directly, which will fail if bun is not installed on the developer's machine. Since this is a fallback path when lefthook is not installed, we should ensure it is compatible with environments that only have node installed, or check for bun's existence first.

if command -v bun >/dev/null 2>&1; then
  bun scripts/check/check-docs-sync.mjs
  bun scripts/check/check-t11-any-budget.mjs
else
  node scripts/check/check-docs-sync.mjs
  node scripts/check/check-t11-any-budget.mjs
