v0.3.0

Added

• Domain scaling — modules can be grouped into domains/<domain>/ with GATEWAY.yaml boundary enforcement (Check 24)
• Multi-agent coordination — claims system (anma claim/release/claims), git hooks (post-merge, pre-commit)
• Incremental sync — hash-based change detection skips unchanged TESTS.yaml (8.8x speedup at 200 modules)
• Accurate token counting — tiktoken support with len//4 fallback via tools/tokenizer.py
• tools/discover.py — module and domain discovery across flat and domain layouts
• tools/claims.py — lightweight module ownership coordination
• --domain flag on new_module.py and import_contracts.py
• --regenerate-only and --force flags on sync_all.py
• sync command in anma.py CLI
• Retrofit support — init_project.py and sync_all.py create missing project files
• Scaling benchmark (tools/benchmark/bench_scaling.py) — 39 tests across 3 features
• Architectural quality comparison tool (tools/benchmark/compare_quality.py)

Fixed

• 17 bugs found via dynamic workflow bug hunt (command injection, YAML corruption, silent drops)
• 3 security findings (path traversal validation, domain kebab-case check, claims YAML injection)
• smoke_test.py — SCAFFOLD_ROOT split, missing tools, stale module names, dependency-order removal
• init_project.py — missing main() function (pre-existing anma init crash)
• check_principles.py — domain modules silently skipped by P1-P7 checks

Changed

• License changed from BSL 1.1 to Apache 2.0
• Linter check count: 22 → 24
• Test count: 91 → 218 (189 linter + 29 regression)
• CONVENTIONS.yaml bumped to v3 with domain_scaling section
• CLAUDE.md instructs agents to always use domain layout
• Performance: eliminated subprocess spawns in sync_all (3.1x overall, 11.9x sync)
