Code Review
This pull request updates the CODEOWNERS file to reassign ownership, and the changes align well with the description. I've identified a potential issue regarding the order of rules, which could result in incorrect reviewer assignments for files within the .github directory. My feedback includes a specific suggestion to reorder the Infrastructure and Documentation sections to ensure the rules have the intended precedence. Apart from this, the changes are well-implemented.

There's a potential issue with the ordering of the Infrastructure and Documentation rules. In a CODEOWNERS file, the last matching rule takes precedence.
With the current order, if a Markdown file (e.g., PULL_REQUEST_TEMPLATE.md) is added or modified inside the .github/ directory, the *.md @Copilot rule will override the /.github/ @Claude rule. This would assign the documentation team (@Copilot) as the reviewer for a file that is part of the repository's infrastructure, which should likely be owned by the infrastructure team (@Claude).
To ensure that the infrastructure team retains ownership of all files within the .github directory, I recommend swapping the Infrastructure and Documentation blocks. This will give the infrastructure rules higher precedence.

Pull request overview
This pull request updates the .github/CODEOWNERS file to reassign code ownership from a single owner (@groupthinking) to multiple specialized owners based on file type and directory structure. The changes attempt to distribute review responsibilities across frontend, backend, infrastructure, and documentation domains. However, the PR introduces several critical issues with invalid GitHub usernames and ownership patterns for non-existent files/directories.
Changes:
- Reassigns default ownership from @groupthinking to @codex
- Distributes frontend files (.tsx, .jsx, .css, /frontend/) to @vercel
- Assigns infrastructure files (/.github/, *.yml, *.yaml, Dockerfile) to @claude
- Moves documentation ownership (*.md, /docs/) to @Copilot

The @copilot owner appears to be assigning documentation ownership to an AI system (GitHub Copilot) rather than a human reviewer or valid GitHub team. CODEOWNERS requires valid GitHub usernames or organization teams. If @copilot is intended to represent a team, it should use the organization team format (@org/copilot-team). If these are placeholder names intended for later replacement, they should be clearly marked as such or use valid fallback reviewers.

The default owner @codex on line 4 appears to be a generic/AI system name rather than a valid GitHub username or organization team. CODEOWNERS requires actual GitHub entities that can be assigned as reviewers. If @codex is meant to be a team, use the proper organization format (@org/codex). If this is a placeholder, it will cause GitHub to fail to assign reviewers when PRs are opened, leading to no automatic reviewer assignment for files not matching specific patterns.

The repository currently has no frontend files (.tsx, .jsx, .css) or a /frontend/ directory. Assigning ownership of these patterns to @vercel when they don't exist in the codebase may cause confusion and unnecessary reviewer assignments if such files are added in the future without proper context. Consider whether frontend ownership rules should be added only when frontend code is actually present.

The repository does not contain .go files or /backend/ and /api/ directories, yet ownership is assigned to @groupthinking for these patterns. This creates dead rules in the CODEOWNERS file. Consider removing ownership patterns for file types and directories that don't exist in the repository, or add a comment explaining these are reserved for future use.

Assigning @claude as the owner of infrastructure files (including /.github/) creates a self-referential loop: changes to the CODEOWNERS file itself would require @claude's review. This is problematic because @claude appears to be this AI reviewing system itself, not a human or valid GitHub team. CODEOWNERS requires valid GitHub usernames or team names (format: @org/team-name). Verify that @claude, @vercel, @Copilot, and @codex are actual valid GitHub users or organization teams that exist and can be assigned as reviewers.

The repository does not contain a /docs/ directory. The CODEOWNERS file assigns ownership of /docs/ to @Copilot, but this directory doesn't exist. Documentation exists as .md files in the root directory (README.md, ARCHITECTURE.md, etc.), which are covered by the *.md pattern on line 25. The /docs/ rule on line 26 is unnecessary and creates confusion about where documentation actually resides in this repository.

The ownership patterns show logical conflicts: the *.md pattern assigns @copilot as owner of all Markdown files, but /.github/ assigns @claude as owner of everything in the .github directory. Since .github/copilot-instructions.md exists, there's an ambiguity about who owns it. According to CODEOWNERS precedence rules, the last matching pattern wins, so @claude would own it despite being a documentation file. Consider reordering rules or using more specific patterns to ensure clear, non-conflicting ownership.

Bug: The ordering of rules in CODEOWNERS causes markdown files in the .github/ directory to be assigned to @Copilot instead of the intended infrastructure owner, @Claude.
Severity: MEDIUM
Suggested Fix
To ensure infrastructure documentation is owned by the correct team, move the /.github/ @Claude rule to a position after the *.md @Copilot rule. This will make the more specific directory rule take precedence for files within that directory, aligning with the "last match wins" principle.

Location: .github/CODEOWNERS#L25
Potential issue: In the `CODEOWNERS` file, the rule `*.md @Copilot` on line 25 overrides
the more specific `/.github/ @Claude` rule on line 19 for any markdown files within the
`.github/` directory. This is due to GitHub's "last matching pattern wins" logic. As a
result, infrastructure-related documentation, such as `.github/copilot-instructions.md`,
will be incorrectly assigned to the `@Copilot` team for review instead of the intended
infrastructure owner, `@Claude`. This contradicts the stated intent of the pull request,
which separates infrastructure and general documentation ownership.

Bug: Core TypeScript (.ts) files are not explicitly assigned an owner in CODEOWNERS, causing them to fall back to the default owner @codex instead of the intended team.
Severity: HIGH
Suggested Fix
Add a specific rule to the CODEOWNERS file to assign ownership of all TypeScript files to the correct team. For example, add a line like *.ts @groupthinking to ensure that changes to the core application code are reviewed by the intended developers.

Location: .github/CODEOWNERS#L7-L9
Potential issue: The `CODEOWNERS` file lacks an explicit rule for TypeScript (`.ts`)
files, which constitute the core application code. Consequently, all `.ts` files fall
back to the default owner, `* @codex`. This appears to be an unintentional change, as
the previous default owner was `@groupthinking`, and the pull request description
focuses on file types like `.tsx` and `.jsx` that do not exist in the repository. This
misconfiguration will route all pull requests for the main application logic to the
wrong team for review, disrupting the development workflow.
