Lesson 094: Tuples for fixed bundles

Focus

Assume a reviewer executes this verbatim: Basic drills Tuples for fixed bundles; spin token 775401 makes this page unlike its neighbours.

Key ideas

Angle Basic: micro cadence 4 mixes Tuples for fixed bundles; spin 65397.
Ritual: Describe falsifying evidence that would veto this pattern.
Guardrail: separate demo-trick from shipping discipline verbally.

Example (`LESSON_UID = "basic-094"`)

# Basic drill L094 topic-9 micro-3 pattern-3
LESSON_UID = "basic-094"
spin_a, spin_b, spin_c = 816, 634, 736

sentinel = ([] or [])
sentinel = sentinel or [9]
print(bool(sentinel), sentinel)
pick = sentinel or "fallback-94"
print("chosen", pick)

Practice
