Measured across all 136 hand-written pages, the twelve hardest to read were all
in prompting/. These ten were untouched — 29% to 40% of their sentences ran over
28 words, against a site median under 15%.
media-and-audio 39.7% -> 6.2% 15 semicolons -> 6
visual-specs 37.1% -> 19.0% 11 -> 9
weekly-updates 39.1% -> 0.0%
runtimes-and-3d 34.1% -> 17.5%
design-systems 34.0% -> 4.3%
recreating-references 33.3% -> 7.3% 16 -> 1
storyboards 31.9% -> 5.4%
variables-and-templating 30.3% -> 7.3%
generated-artwork 29.4% -> 9.1%
explainers 29.1% -> 3.3% 12 -> 1
Word counts barely move — 1752 to 1748, 1633 to 1617 — which is the point. The
facts and worked examples all survived; the sentences carrying them got shorter.
weekly-updates is an archive, so no date, version or fact changed there at all.
One anchor came back: capstone#the-full-prompt-verbatim, which these pages link
to and which an earlier commit had already moved to #the-prompt-word-for-word.
Repointed. Branch total: 0 broken pages, 0 broken anchors.
Thirty-two published videos were the raw render output. One 20-second catalog
preview was 60 MB at 25 Mbps — Blu-ray bitrate for a screen capture in a docs
page. Nothing autoplays, so no page shipped that silently, but a reader who
pressed play paid for it.
Re-encoded at 1280 wide, CRF 28, faststart, keeping audio where it existed.
Measured PSNR against the originals at ~38.5 dB, which is visually identical —
the first check I ran returned nothing and I mistook that for a pass, so this
number comes from a filter that actually worked.
Worth correcting one thing I said earlier: the catalog is not systemically
over-encoded. 190 videos, 0.36 GB, about 1.9 MB each. Six were over 10 MB. I
found two monsters and generalised from them.
Pages carrying more than 8 MB of video: 26 before, and the heaviest went from
140 MB to under 15 MB.
The durable fix is in generate-catalog-previews.ts, which had no delivery encode
at all — it published the render master directly. It has a web pass now, so the
next preview is born small instead of being cleaned up later.
The capstone and determinism rewrites renamed headings that other pages point at.
Eighteen prompting pages linked to capstone#the-full-prompt-verbatim, which is now
'The prompt, word for word', and the rewritten determinism page invented an anchor
on frame-adapters that was never there.
Moved the links rather than restoring the old headings — 'the full prompt,
verbatim' is exactly the register the rewrite was cleaning up.
Broken anchors site-wide: 0. mint broken-links does not check anchors, so none of
this would have failed CI.
Level 2 (anatomy, specification-dial, vocabulary, visual-specs, examples)
gets entry/exit bridges tying it into the Level 1 -> Level 3 arc, plus a
short note on the composition-structure mandate (0aaac7aa3 / PR #2599)
showing the framework enforces its own version of the prompt skeleton.
All existing prompts, renders, and tables are untouched.

Validates 16 more published prompts end-to-end (variants across every
video type, caption styles, overlays with proven alpha, code diff and
highlight, edit verbs against the real attribute map, a generated-avatar
talking-head through embedded-captions, a presented slideshow deck) and
fixes every prompt flaw the builds surfaced. Adds keyword-to-render
grids for the easing, camera, and marker vocabulary; two more worked
visual specs with renders; a measured before/after pair proving the
motion grammar (frozen frames vs all-alive, 211KB vs 2.5MB); before/
after render pairs on editing and generated-artwork pages; and proof
renders on the overview.

Five-way review of the section against docs.json, catalog pages, and
skills. Fixes: stale /hyperframes-media skill row (real name /media-use)
plus missing music-to-video and slideshow workflow rows; caption
identity misattributions (keynote/documentary are scene-embedded, stomp
carries no rail); prompts violating the guide's own ambient-idle rule;
grounded keying rationale (u2net_human_seg); broken forward references;
nested-backtick code spans; brand casing and frontmatter dash
consistency throughout.

Splits guides/prompting into a Prompt Guide nav group (overview + Fundamentals
+ Making it look good, 11 pages) with a redirect from the old URL. Applies
research-validated upgrades: beat content formula, before/after prompt rewrites
with engine rationale, single-variable iteration moves, absolute-target
calibration, camera/depth/pacing vocabulary, prerequisites gate.
