Collects what this session exposed into one actionable document: the five bugs fixed in 0.8.6 and the guard protecting each, the places the model is incomplete, the smaller defects, and the delivery and dev-loop problems. Every item states the issue, the evidence, the change and a test that fails before it. Where a cause is not proven -- the dev server not picking up packages/ui edits -- the item says so and makes diagnosis step one rather than asserting a fix. Two standing conventions are written down at the top because the rest is written against them: a component owns its markup, behaviour and styles in its own .wrn file, and ui.css carries global styles only; and a test that still passes with the fix removed is measuring nothing, which is how the 0.8.5 focus trap shipped with no coverage.
