Гейт

• scripts/check-consumer-size.js + release/consumer-size-ratchet.json: точный baseline + max-потолок, measurement pinned к esbuild@0.28.1/fflate@0.8.3.
• test/consumer-size.test.js: tree-shake в измерении, укусы baseline/max в обе стороны, fail-closed формы, parse-граница.
• check:consumer-size подключён в pnpm verify рядом с package-size.
• Sabotage: занизили max+baseline one-static → exit 1 (2 нарушения) → откат.

Verify exact head: 71 files / 812 tests, exit 0 (локально; авторитет — CI PR). Отчёт: epics/ds-icons/reports/size-01-budgets.md.

Summary by CodeRabbit

• New Features

  • Added automated consumer bundle-size checks for static imports, individual glyphs, the full catalog, and recipe-only imports.
  • Added configurable baselines and maximum raw/gzip size limits to detect unexpected bundle growth.

• Documentation

  • Added a report documenting bundle measurements, size attribution, budgets, and recommended optimization priorities.

• Tests

  • Added coverage for size validation, threshold violations, malformed configuration, invalid scenarios, and tree-shaking behavior.

• Chores

  • Integrated consumer-size validation and package-quality checks into the verification pipeline.

📝 Walkthrough

Walkthrough

Added a consumer bundle-size ratchet with four configured scenarios. The checker validates metadata, bundles entries with esbuild, measures raw and gzip sizes, enforces baselines and ceilings, and runs through the verification pipeline with Vitest coverage.

Changes

Consumer size ratchet

Layer / File(s)	Summary
Define size budgets and verification wiring epics/ds-icons/reports/size-01-budgets.md, release/consumer-size-ratchet.json, package.json	Added four consumer bundle scenarios, size baselines, maximum limits, reproducible measurement details, and verification commands.
Implement ratchet parsing and measurement scripts/check-consumer-size.js	Added strict configuration validation, package aliases, esbuild bundling, tree-shaking, gzip measurement, baseline checks, ceiling checks, and CLI reporting.
Validate successful and failing scenarios test/consumer-size.test.js	Added fixture-based tests for stable measurements, tree-shaking, size changes, limit violations, malformed metadata, invalid imports, and invalid scenario names.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 24731

The PR adds automated consumer-size budgets, but the current checks can accept a scenario without a real package import and may fail to detect retained unused code. That could allow the size gate to pass while measuring the wrong bundle or missing a tree-shaking regression, so the PR needs these bounded correctness gaps addressed or explicitly accepted before merge.

In `@scripts/check-consumer-size.js`:
- Around line 96-98: Update the limits.entry validation in the consumer-size
checker to parse and require a real static import from `@labpics/icons` rather
than accepting arbitrary matching text. During bundling, verify that the
configured package entry contributes output bytes, and add coverage for this
scenario in the parse-boundary tests.

In `@test/consumer-size.test.js`:
- Line 25: Update the tree-shaking fixture and assertion in the consumer-size
test so retaining the unusedFilled export cannot remain under the 90-byte
threshold; use a substantially larger unusedFilled literal or directly verify
that emitted bundle content excludes it, while preserving the alertFilled export
behavior.
