0:00The dumpA refund button behind a flag, an unwritten README, a legal email, a rename morning, two days next week, a dentist visit that must stay private.
0:08What is trueShipped means merged, not enabled. The three test checks are not done. The rename did not change the product.
0:16Three betsRun the three refund checks. Send one legal ping. Everything else waits. The README is on the drop list for this week.
0:24The scrapThe dentist stays out of the shareable review and is listed only under private, as the author marked it.
No daily video for this drop yet. The in and out lines above are the preview.
0:00The evidenceSupport ticket prompt. Wanted JSON for the on-call engineer. Got four friendly paragraphs and no severity.
0:08Bug 1: rules that fight'Be concise' vs 'cover everything the customer said'. The model picks 'everything' and writes four paragraphs.
0:16Bug 2 and 3'Always be friendly!!' outranks the format, so it writes to the customer. 'Output JSON' has no schema and no example.
0:24Fixed promptReader named, friendliness rule cut, JSON schema with one filled example, and a 'no prose outside the JSON' line. Each change tied to a bug.

0:00The diff that 'works'A Next.js DELETE handler reads an id from JSON, concatenates it into SQL, and returns a live-looking secret key in the response.
0:08What it should catchA secret in source. SQL built with string concatenation. No check that this caller owns the note. The key echoed back to the client.
0:16Severity, then the fixHigh: move the key to an environment variable and rotate it. High: parameterize the query. High: derive the user from the session and filter the delete by owner.
0:24What it will not doIt will not hand you a working exploit. The sample key is fake. The output is the safer handler, not a payload.
