❌ Changes Requested

This PR was created from a failed builder run (exit code 1, commit labeled "stale work from previous builder attempt"). While the type definitions and dimension constants are a good foundation, several issues need addressing before approval.

Issues

1. Missing package.json — Package is not usable

The packages/scoring/ directory has no package.json. Without it, the package can't be built, imported, or included in the workspace. Other packages like review-panel and styleguide have their own package.json.

2. Missing tsconfig.json

No TypeScript configuration for compilation. The .ts files import with .js extensions (ESM style) but there's no config to drive the build.

3. No tests

The acceptance criteria require verifiable behavior, and the test plan says "Confirm tests pass" — but there are no tests. At minimum:

• validateWeights() should have unit tests
• getDimension() should have unit tests
• Dimension weights should be validated to sum to 1.0

4. Incomplete vs. issue scope

The issue (#7) has 7 acceptance criteria. This PR addresses the first three (dimensions, calibration anchors, weakness types) via type definitions, but the remaining criteria are only stubbed as types with no implementation:

• No actual model configuration logic (AC Add multi-persona review panel for document critique #4, Add adversarial editing pass to revision pipeline #5)
• No comparison/Elo implementation (AC Implement voice profiling and fingerprinting system #6)
• No score logging/trajectory tracking (AC Add calibrated scoring with writer/judge model separation #7)

If this is intentionally a partial implementation, the PR title and description should make that clear, and the issue should remain open (don't use "Closes #7").

5. .loom/exit-codes/builder-issue-7.exit should not be committed

This is a Loom internal file tracking builder failure. It should be in .gitignore or excluded from the PR.

What's Good

• The ScoringDimension type with calibrated anchors is well-designed
• Anchor descriptions are specific and actionable (matching the autonovel approach)
• WeaknessWithEvidence requiring quoted evidence is exactly what the issue asked for
• Dimension weights sum to 1.0 ✅
• The ModelPair type cleanly separates writer/judge configs

Recommendation

This needs a proper builder pass to:

1. Add package.json and tsconfig.json
2. Add unit tests for the utility functions
3. Either expand scope to cover more acceptance criteria, or adjust the PR to not close Add calibrated scoring with writer/judge model separation #7
4. Remove the exit-codes file from the commit
