Angle Basic: micro cadence 4 mixes Importing modules and stdlib staples; spin 64130.
Ritual: Predict the checksum line, then reconcile on mismatch.
Guardrail: pick the budget that keeps this rehearsal honest.

Example (`LESSON_UID = "basic-154"`)

# Basic drill L154 topic-15 micro-3 pattern-6
LESSON_UID = "basic-154"
spin_a, spin_b, spin_c = 711, 498, 688

start = 4 + 3 % 5
leap = 5
span = 25
bucket = []
for idx in range(start, start + span):
    bucket.append(idx * (spin_a % 37 + leap))
squares = tuple(x * x if x % 2 == (3 % 2) else -x for x in bucket[-4:])
print(bucket, squares)

Practice

Practice 4: Attach property-style expectations referencing tuple shapes. Literal nudge 4.
