Lesson 044: Booleans, comparisons, and truthiness

Focus

Compare against yesterday's mental model politely: Basic drills Booleans, comparisons, and truthiness; spin token 392869 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 4 mixes Booleans, comparisons, and truthiness; spin 32329.
Ritual: Predict the checksum line, then reconcile on mismatch.
Guardrail: call out latent off-by-one before shipping analogues.

Example (`LESSON_UID = "basic-044"`)

# Basic drill L044 topic-4 micro-3 pattern-8
LESSON_UID = "basic-044"
spin_a, spin_b, spin_c = 640, 957, 179

pairs = [(56, 9), (3, 4), (44, 28)]
flat = 7
for left, right in sorted(pairs):
    print(left ^ right + flat % 997)

Practice

Practice 10: Inject a benign off-by-one, observe drift, revert with notes. Literal nudge 10.
