Onus v0.3.0

• Sharper reports and onus_check:
  • Untyped values are compared key by key (Schema.struct({...}), z.object({...}), object literals), and union types member by member.
  • Changes Onus cannot compare are one low-confidence row instead of a "may have changed" row each.
  • Production code that uses an API of an already-used package for the first time is reported with the pinned version.
  • Breaking contract rows name the implementations and test doubles not updated.
  • Changes in components of more than 300 files name their module folders.
• onus_check for agents: it returns a checklist of what to verify before finishing, and states what it does not verify, so a clean result is evidence, not approval.
• The map for coding agents (experimental): onus mcp serves the map of a worktree as MCP tools (onus_status, onus_find, onus_symbol, onus_dependents, onus_dependencies, onus_tests_for, onus_owners, onus_component, onus_file, onus_check), and onus query asks the same questions from a shell. Every agent and worktree of a repository shares one map server, which follows file changes and re-parses only changed files, sharing per-file facts across worktrees (ADR 0007). An evaluation found no measurable gain from the navigation tools for agents implementing features, so they are marked experimental and Phase 2 focuses on onus_check.
• onus find ranks symbols by how many query words match (name, then fields and parameters, then path), finds the types that declare a field, and always lists matching files, instead of returning nothing unless every word was in one name.
• Mapping a large monorepo is about 25% faster (4.6 s to 3.5 s on Twenty's 31,000 files) with byte-identical maps: public methods are found without a quadratic scan, components are matched with one glob set, packs compile once per process, the file walk is parallel and module resolution is cached.
• The Homebrew tap is updated by a reusable Homebrew tap workflow that the release calls. Run it by hand to re-sync the tap, or as a dry run to check that HOMEBREW_TAP_TOKEN can still push. Release notes include the brew install line.
