The side panel.

For the rest of this thread, end every action you take with a one-line "Verify:" pointer telling me which side panel tab shows the evidence and what I should see there. Examples:

- Verify: Files → src/app.ts shows the new function highlighted.
- Verify: Terminal → test run with 14 passed, 0 failed.
- Verify: Browser → reload shows the new header layout.

If an action produces no panel-visible evidence, say "Verify: none — take my word for it" so the gaps are visible too. Start now by doing a trivial demonstration: list this folder and point me to where I can see the command output.

Using the Files tab as our shared map:

1. List every file you've created or modified in this thread, with full paths and a one-line reason for each.
2. Name the five files in this project you'd read first if you were onboarding a new developer, and why those five.
3. Point out anything in the tree that surprised you when you first read this project — generated folders, naming oddities, things that look misplaced.

I'll follow along in the Files tab. Where a file you mention is one you changed, tell me so I can open it and look at exactly what's different.

(Ask this in the side chat while a task runs in the main thread.)

Without changing anything about what you're doing in the main thread:

1. Explain the approach you're currently taking and the main alternative you considered but rejected.
2. What's the riskiest assumption in the current plan?
3. If this approach fails, what would the failure look like, and what's plan B?

Answer as commentary, not as new instructions — the main thread's plan stays exactly as it is unless I say otherwise over there.

Before I review your changes, review them yourself — as a skeptical senior engineer who did not write this code.

1. Walk the full diff. For each file: what changed and why it's safe.
2. Hunt specifically for: unintended changes (things in the diff that don't serve the task), broken assumptions (code that works only if something else is true), missing pieces (the task says done, but an edge is unhandled), and anything that touches files outside the task's scope.
3. Rate your confidence per file: high / medium / look-at-this.
4. Hand me a review order: which files deserve my human eyes first and what to look for in each.

Then wait. Do not consider the changes accepted until I've walked the Review tab myself.

For all command execution in this thread, use announce-then-run:

Before each command, one line: `command` — why I'm running it — what success looks like.
After it finishes, one line: ✓ matched expectation, or ✗ unexpected, with what differed and what you'll do about it.

If a command fails twice, stop and bring it to me instead of trying a third variation silently. Start with the project's test suite (find the right command from the repo's config), and let me watch the pattern in the Terminal tab.

The page in your browser panel doesn't look right to me and I suspect stale state. Run the un-lying protocol:

1. Tell me what URL/file is loaded and when it was last rebuilt or reloaded.
2. Force reload. Did anything visibly change? Say what.
3. If it still looks wrong, walk me through the order of operations: clear cache, then clear cookies, then reload again — and explain what each step rules out.
4. If the page still misbehaves, check the dev server: is it running, did the last build succeed, is the browser even pointed at the right port?
5. Conclude: was it stale state, a build problem, or an actual bug — and what's the fix?

I'll paste a screenshot from the browser panel if you need to see what I see.
