FAQ
Questions, answered.
The short version: no account, no saved profile, five faults per challenge, and a deterministic score at the end.
Do I need an account?
No. The current release is guest-only. You can start any challenge without signing in.
Is my progress saved?
No. A guest result is shown once after submission and is not added to saved history or progress. Guest attempt rows are deleted after grading.
What happens to the reports I write?
They are graded against the hidden answer key and then deleted with the guest attempt. Abandoned guest attempts are targeted for deletion after 24 hours. Do not type real personal data into a report.
How is scoring calculated?
Each challenge has five active faults worth 100 points each. A report must identify the correct component and at least one of category or severity. Matching is weighted 40/35/25, and an unmatched report costs 25 points. A challenge is passed at 70%.
How long does a challenge take?
Most challenges have a 20–25 minute timebox. The timer is server-owned and starts when you start the attempt.
Can I retake a challenge?
Yes. Guest attempts do not resume, so starting again creates a fresh attempt with a fresh timer.
Are the sandboxes real products?
No. They are fictional products built for practice. The checkout is a simulator and no real money or payment data is involved.
Do you offer certificates, leaderboards, teams, or saved history?
Not in the current release. It is a guest-only practice lab. Those features may be added later.
Which browsers and devices are supported?
The app is responsive and works in current desktop and mobile browsers. There is no formal browser-support matrix; if something breaks, use the Contact page.
How do I report a bug in Faultline or an accessibility issue?
Use the Contact page. Include the page URL, browser/device, what you expected, what happened, and the approximate time.
How do I exercise my privacy rights?
Use the help address on the Contact page. Guest attempts are not linked to an identity, so include the attempt identifier and approximate time if you have them.
Why are accounts off?
The first production release is guest-only so the practice lab is usable without collecting account data. Accounts, saved history, and deletion/export flows will be added together if they return.
