/claim #71

Summary

• Expands src/literest/index.test.ts with focused coverage for LiteREST primary-key discovery, request parsing, CRUD validation/error branches, and select-query filter construction.
• Covers PostgreSQL/MySQL primary-key metadata queries, SQLite primary-key filtering, empty REST paths, empty POST/PUT bodies, PATCH without updatable fields, PUT/PATCH/DELETE operation failures, no-primary-key DELETE, and IN/LIKE filter construction with sanitized default ordering.
• Test-only and intentionally non-overlapping with the active CSV, JSON, dump import, RLS, cache, allowlist, operation, worker, handler, Durable Object, and plugin coverage PRs. No production behavior changes.

Coverage

• Before this slice, local focused coverage for src/literest/index.ts was 81.94% statements, 66.92% branches, 90.32% functions, 82.67% lines.
• After this slice, src/literest/index.ts reports 97.68% statements, 83.46% branches, 100% functions, 98.01% lines.

Validation

• pnpm exec vitest run src/literest/index.test.ts - passed, 38 tests.
• pnpm exec vitest run src/literest/index.test.ts --coverage.enabled true --coverage.include src/literest/index.ts --coverage.reporter text --coverage.reportsDirectory coverage-literest-after --coverage.thresholds.lines 0 --coverage.thresholds.branches 0 --coverage.thresholds.functions 0 --coverage.thresholds.statements 0 - passed; coverage listed above.
• pnpm exec prettier --check src/literest/index.test.ts - passed.
• pnpm run build - passed.
• git diff --check - passed.
• pnpm exec vitest run - LiteREST suite passed; current repo baseline still has 4 existing unrelated src/rls/index.test.ts failures.
• pnpm exec tsc --noEmit --pretty false - no LiteREST test errors; current repo baseline has existing unrelated type errors in plugins/cdc, src/cache/index.test.ts, src/do.test.ts, and src/operation.ts.

No UI demo video is included because this is backend/unit-test-only coverage with no visible UI or runtime behavior change.
