--[ Challenge Description ]--
│ The prompt asked for the date of mdhdlimv2 and gave the format
boroCTF{month/day/year}.
────────────────────────────────────────────────────────────────────────────────
--[ Recon / Initial Analysis ]--
The "140 years, not hours" phrasing pointed toward a well-known long-duration
YouTube/video clue connected to shinywr.
The relevant YouTube description contained an archived link labelled with an
exaggerated hour count, which was the real pivot.
────────────────────────────────────────────────────────────────────────────────
--[ Vulnerability / Observation ]--
The archived page pointed at a video titled exactly mdhdlimv2.
The upload date on the archived video page was 6 Apr 2026, which needed to be
converted into the challenge's month/day/year flag format.
────────────────────────────────────────────────────────────────────────────────
--[ Exploitation / Solution ]--
1. Use the prompt wording to identify the shinywr video clue.
2. Open the archived link from the video description rather than only inspecting
the live page.
3. Find the archived video titled mdhdlimv2.
4. Convert the displayed date into 4/6/2026 and submit it.

--[ Full Exploit Script ]--
No script was needed; the solve depended on following the archive trail.
────────────────────────────────────────────────────────────────────────────────
--[ Key Takeaways ]--
- Archive links in descriptions can be the intended source of truth.
- Keep the requested date format exact; this challenge used month/day/year.
- When a prompt says a number is not hours, use that as a semantic correction
rather than a math operation.
