Challenge 2: What Path C's Extra Time Actually Bought -- Solution
Walkthrough

Path C didn't buy a better outcome on Criterion 3 specifically --
per Exercise 1, all three paths already reached the same full result
there. What the extra time in Path C actually bought, per this
chapter's own comparison table, was the best result on Criterion 2
(pacing): Descript's transcript-based editing let Dana review every
filler-word suggestion individually rather than accepting a bulk
removal, deliberately keeping one genuine pause right before the
Pydantic explanation so a first-time viewer gets a real beat to
absorb what's coming -- a level of pacing control neither Path A's
live, unreviewed zoom timing nor Path B's single review pass on the
cleaned script could match.

The extra time also bought a small but real polish improvement on the
one trickiest sentence: rewriting it slightly and re-voicing it with
Overdub in her own cloned voice, without needing to re-record the
entire take to fix one moment. Path C's own row in the comparison
table describes this as "highest polish ceiling" specifically because
of this combination -- full manual pacing control plus the ability to
surgically fix one weak moment -- not because it produced fundamentally
better legibility or a fundamentally different narration outcome than
the other two paths.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that the reader can identify precisely which
criterion benefited from the extra investment (pacing, plus a small
polish win) rather than assuming more time spent must mean a uniformly
better result across every criterion -- Criterion 3 was already fully
satisfied in all three paths, so the extra time in Path C bought
something specific and real, not a general quality upgrade.
