"""Prompt-bank extension: the diversity fix FINDINGS §7 item 0b calls a blocker.

96 prompts / 432 clips is what v5 trained on, and it is the stated reason the
rolling-K/V work improved world_p0 and failed to generalise to the other three
worlds. At effective batch 64 the old bank is nine iterations per epoch. This
module adds 904 prompts to reach 1000.

TWO RULES THIS FILE FOLLOWS, AND WHY.

1. **It never touches indices 0-95.** `prompts.py` keeps its original bank
   verbatim and `prompt_bank()` appends this module afterwards, so prompt 0 is
   still the talking head, 44 the owl, 60 the waterfall and 82 the court. Those
   four are `out/world_p{0,44,60,82}.pt` and every 1:1 comparison in FINDINGS;
   renumbering them would silently invalidate the entire before/after evaluation
   and the teacher clips already generated for them.

2. **Same composition discipline as the original.** Stable subject, continuous
   non-cut motion, one scene per prompt. No hard cuts, no crowds, no rapid scene
   changes -- a block-causal model with a sliding K/V window cannot represent
   them, so training on them teaches nothing it can keep. Roughly half remains
   human subjects for the interaction use case.

What is deliberately WIDER than the original bank, since narrowness was the
defect being fixed: many more trades, activities and interiors; the same kind of
subject under different times of day, weather and light; more variation in
framing distance, in how much of the frame the subject occupies, and in how fast
the motion is. Content type, lighting and setting vary as independently as a
hand-written list can manage, so the student does not learn that (say) a
workshop implies warm light.

# One in-place substitution in the ORIGINAL bank. Index 20 was
# "A child blowing bubbles in a garden" -- this bank is to contain no minors,
# and deleting the entry instead of replacing it would renumber prompts 21-95

# (court), which are referenced by index everywhere in FINDINGS and by
# `demo.py --prompt-idx`. Substituting the text keeps every index where it was.
#
# Consequence to act on: the six teacher clips already generated for prompt 20
# (`data/teacher/p0020_s0*.pt`) were made from the old text and must be deleted
# so `gen_teacher.py` regenerates them. Nothing else is affected.
