An MCQ-based stream. One-liner questions with 4 options, then one-liner explanations of why each is right or wrong. Every wrong answer is plausible to a hasty reader — that's what makes it work.

What it does
Sift takes a syllabus and turns it into a stream of multiple-choice questions. Each question forces a choice; each choice forces a justification. The reader doesn't just recognize the right answer — they understand why the three wrong ones feel almost right, which is where real understanding lives.
To sift is to separate the fine from the coarse. The mode separates what you know from what you merely recognize.
When to use it
You've learned a subject once (maybe via Thread) and need to lock it in.
You're preparing for an exam, interview, or certification.
You want to expose your own blind spots — the wrong answers you almost picked.
You're reviewing material you've seen before but don't fully own.
The structure
Each question is 4 options. Exactly one is right. Each option gets a one-line explanation. Between every 4 questions, a checkpoint with 2 short-answer recall questions — answers deferred.
─── EXAMPLE · Q1 ───
🧩 CONTEXT
We just learned a system is a pattern of interaction, not its parts.
❓ Q1: A clock is on the table. You take it apart and lay the gears
on the table. The clock is now…?
A) Destroyed — the parts no longer work
B) ✅ A collection — the parts are intact, the pattern is gone
C) Still a clock — the system exists independent of arrangement
D) A different system — the gears now interact with the table
✅ Why B is RIGHT: A collection has the parts without the pattern of
interaction; that's exactly what remains.
❌ Why A is WRONG: "Destroyed" implies the parts are gone. They aren't.
❌ Why C is WRONG: The system is the pattern. No pattern, no system.
❌ Why D is WRONG: The gears on a table aren't interacting with the
table in any meaningful pattern.
🔗 TETHER: This matters because in Phase 4 we'll see that some
systems can be "moved" — the same pattern in different parts.
─── EXAMPLE · Q2 ───
❓ Q2: Two cities have the same traffic system — same rules, same
signals, same patterns of flow. Is it one system or two?
A) One — they're identical
B) ✅ Two — they share a pattern but exist independently
C) Neither — a system needs physical parts, not just rules
D) One — a pattern is a system
✅ Why B is RIGHT: They share the pattern, not the parts.
Each city is its own system with its own parts.
❌ Why A is WRONG: Identity of pattern doesn't mean identity of system.
❌ Why C is WRONG: "Rules" can function as the parts of an abstract system.
❌ Why D is WRONG: A pattern can be instantiated in many systems
(or zero).
📍 CHECKPOINT
1. In one sentence, what makes a system a system?
2. Why is a pile of gears not a clock?
