F2 code quality review - APPROVE

What was tested

• Historical npm run check && npm test in the ulw-loop component after original feature fixes.
• Reviewer-fix npm run check and full npm test after independent-review blocker fixes.
• Pure LOC audit on every changed TypeScript file using awk '!/^[[:space:]]*$/ && !/^[[:space:]]*\/\//' <file> | wc -l.
• Forbidden construct audit over the diff for as any, as unknown, @ts-ignore, non-null assertions, default exports, and enums.
• Given/when/then discipline audit in new/changed tests.

Gate output

• npm run check: passed (tsc --noEmit, biome check ., tsc -p tsconfig.build.json).
• Historical npm test: passed (40 files, 412 tests).
• Reviewer-fix npm test: passed (40 files, 418 tests).

Pure LOC audit

All changed TypeScript files are <=250 pure LOC; steering.ts is 203, under its stricter 240 budget.

Forbidden construct audit

No matches in the diff for as any, as unknown, @ts-ignore, non-null assertions, default exports, or enums.

Test style audit

New/changed tests contain given/when/then naming or comments. Counts after reviewer fixes include checkpoint-continuation 3, cli-checkpoint-continuation 2, cli-steering-batch 3, cli-validation-batch 2, steering-batch 5, validation-batch-checkpoint 6, validation-batch 6.

LSP diagnostics note

The LSP tool rejects paths outside the request cwd (/Users/yeongyu/local-workspaces/omo), and this task worktree is /Users/yeongyu/local-workspaces/omo-wt/ulw-loop-batch-efficiency-v2. I attempted diagnostics and received LSP file path must be inside request cwd. TypeScript diagnostics were covered by tsc --noEmit in npm run check and npm run typecheck during focused fixes.
