Interactive repair lab

Don’t take my word.
Run the fix.

Three intentional bugs. Real checks in your browser. See the break, inspect the repair, then export the evidence.

Repair your own sanitized HTML/CSS locally, or run the three synthetic checks below. Results begin pending.

CASE 01 / DOM WEIGHT

The page that renders everything.

The broken catalog mounts every item. The repair keeps all 6,000 searchable, while only a bounded page reaches the DOM.

LIVE EVIDENCE

02 / METHOD

Evidence, not theatre.

01

Same fixture

Before and fixed views use the same deterministic synthetic content and search rules.

02

Browser observed

DOM work uses performance.now() and animation frames. Layout checks read rendered dimensions. Click checks operate the form.

03

Honest limits

These are local fixture measurements, not Lighthouse or Web Vitals. Device load and browser conditions affect timing.
