NULL ORIGIN CTF OBSERVATION MISSION REHEARSAL

Aircrew pre-flight for the 2-laptop + phone squad (Rob, CindyL789). A recorder operator logs delays and confusion; failure cards are injected; three numbers are measured (TTFA < 2 min, TTFS < 15 min, TTSS < 60 s); scores below 8 become fix items. The challenge is a vehicle — the workflow is what's being tested.

READ CHALLENGE→ USE COMPANION→ DEVELOP SOLUTION→ HUMAN REVIEWS→ HUMAN SUBMITS→ LOG OUTCOME

1. Environment Check

Extension icon active, sidebar opened, desk connected on localhost:8100. Recorder starts the mission clock.

2. Deck Switch

[⇄ Mode] toggles CTF Deck / Huntr Deck. Measure how long switching takes.

3. No-AI Send Gate

Companion stages the flag; the human must click Submit. Measure TTSS: fill → human submit.

Red-Team Question (ask each operator right after the run: "If NULL ORIGIN started now, what worries you most?")

Rehearsal Debrief Checklist

Check Item	Pass / Fail	Expected Behavior	Operator Notes
Sidebar Attached	⏳ Testing...	Sidebar renders on right margin with Athelgard owl avatar	Loaded via `http://localhost:8100/sidebar.zip`
Simli Face & Audio	⏳ Testing...	WebRTC session minting active with Athelgard avatar	Probing /api/simli-session...
CTF Deck Mode	⏳ Testing...	Displays Web, Crypto, Rev, Pwn, Forensics buttons	Click `[⇄ Mode]` if in Huntr deck
Flag Detection	⏳ Testing...	Scrapes `synt{...}` and suggests ROT13 decode	Simli audio coach suggests CyberChef / rot13
No-AI Send Gate	⏳ Testing...	Extension populates `#flag-input` but does NOT click Submit	Zero DQ risk on human-only platforms
Metrics Recorded	⏳ Testing...	TTFA / TTFS / TTSS populate and export with the friction log	Recorder presses START at H-00
