Intro
Most QA still lives in screenshots and spreadsheets.
You click, you test, you describe what broke.
But the truth isn’t in words — it’s in state.
What the page really looked like before and after.
That’s where runtime snapshots change the game.
Before / After
Take one snapshot before your test run.
Take another right after.
Each one is a full runtime JSON — visibility, validation, attributes, inner state.
Drop them both into Slack.
Now your QA thread doesn’t tell a story — it shows one.
You see the change. You see the cause.
LLM context, naturally
Each snapshot doubles as a prompt context.
Snapshot + question = answer that actually understands your UI.
No hallucinations, no screenshots, no “please share repro steps.”
The runtime is the repro.
Why it matters
QA shouldn’t be about bureaucracy.
It’s about making sense of what happened.
Snapshots make that sense portable — for humans, for LLMs, for history.
E2LLM — contextualize.
