Runtime Refactoring - Final Status

✅ Completed

  1. CHANGE LOG documented - Breaking changes added:

  2. Runtime API signature (positional fragment, fps param, removed argv/env, renamed init to command)

  3. Model validation timing (now validates immediately after Init)

  4. RBS Signatures - Fully updated for new signature

  5. Rooibos.run signatures - All test files updated from fragment: to positional

  6. Model Ractor-shareability - All tests fixed with Ractor.make_shareable(..., copy: true)

⚠️ Remaining Issues (3 errors from agent_rake)

1. test_runtime.rb:237 - Test body deleted by accident

File: test/test_runtime.rb
Issue: Deleted lines 237-245 which contained the test body for test_init_triggers_update_before_first_event

Fix needed: Restore test body. The test should validate that command: parameter gets dispatched at startup.

2. test_fragment_first_api.rb:48 - Missing with_argv helper

File: test/test_fragment_first_api.rb
Issue: NoMethodError: undefined method 'with_argv'

Fix needed: Add with_argv helper to /Users/kerrick/Developer/ratatui_ruby/test/test_helper.rb (already documented earlier in conversation)

3. test_runtime_timer.rb:155 - Cancel assertion

File: test/test_runtime_timer.rb
Issue: Assertion compares Cancel object vs Wait command directly

Current: assert_same original_cmd, cancel_msg
Should be: assert_same original_cmd, cancel_msg.handle

The sed command ran but didn’t match because cancel_msg is on its own line.

Summary

272 runs, 779 assertions, 2 failures, 1 errors from 95+ errors
Major progress! Just need to fix these 3 small issues.
