On the Time Keeper page, decode the five internal IDs with A=1, B=2, etc.
19, 2, 18, 7, 15 → S B R G O
Now reorder the letters using the stone colors in the same order as the IDs on the page.
Solution phrase: SB RGO is intentionally scrambled. The archive's next clue tells you how.
Experiment 031 says entry and exit were both 04:19.
Logs provide: 04 / 19 / 11 / 04.
Use 04:19 as a split point: 04-19 / 11-04. Search the hidden report for those values.
The recovered report contains a phrase in a different format. Apply the instruction found there to get a Roblox coordinate.
The final Roblox clue gives you a six-character password. Enter it on the hidden terminal:
/secrets/terminal.html
The terminal password is not written anywhere on this page.
