The Build-Review-Verify Loop

"I want to work in a build-review-iterate loop for this feature.
Start with the smallest reviewable slice that proves the approach.
Goal: [outcome]
Scope: [files, routes, components, or systems in scope]
Proof: [test, command, browser check, or manual check]
Stop condition: [when to stop]
Do not touch: [protected systems]

Before editing, give me a short plan and tell me whether this needs a stronger model, a subagent, MCP, browser control, or a bounded loop.
After you propose or implement that slice, stop and show me:
1. what you changed
2. what assumptions you made
3. what verification passed or failed
4. what could still go wrong
5. what the next iteration should focus on

Keep each iteration scoped to one to three concrete changes.
If we pass five iterations on one feature, tell me to step back and reassess instead of patching blindly."
