**The catalog generator destroys hand-written documentation on every run.** It
does `rmSync(dir, { recursive: true })` on both catalog folders before
regenerating, so any section a human added to a generated page is deleted the
next time anyone runs it. There is now a carry-forward pass that reads those
sections off the existing pages first and re-emits any heading the template does
not own. Note this prevents future loss only — the earlier regeneration in this
stack already removed what was there, and it is recoverable from git if wanted.
It was also clobbering `docs.json`: rebuilding the Catalog tab dropped its icon
and unlinked `catalog/index.mdx` from the sidebar entirely.
And 27 of 36 component pages told the reader to "see the comment header in the
file" when no such header exists. The generator reads the file now and only says
it when true.
On presentation: 1,365 table rows across 168 pages became 0. `## Details` was a
table whose rows were "Type: Block" and the duration; `## Files` was three
columns where most items have exactly one file. Both are one sentence now. The
preview leads the page instead of sitting under title, description, tags, a
warning and a credit — four of which Mintlify already renders from frontmatter.
**Two guides that showed nothing now show the thing.** Background removal plays a
real cutout with the matte magnified at the hair edge and at a shoulder a plant
overlapped, because those are where matting fails. HDR is the honest one: you
cannot show HDR brightness on an SDR page, so it shows the `ffprobe` verdict and
a measured round-trip — 4000 nits authored, 4012 back out — and says on screen
for all 26 seconds that it is not simulating anything.
Both films were checked before publishing: no black or frozen stretches, and read
at the real 590px docs column width rather than full size. Nav after regeneration:
307 pages, 0 dangling, 0 redirect collisions.
## Problem
The Catalog did not include the four prompt-matched Stronkter one-shot HyperFrames projects, and registry metadata only supported a plain author string, so there was no structured way to show creator attribution or the original generation prompt on generated catalog pages.
## What this fixes
- Adds four Catalog blocks matching the provided prompts, in order:
- `north-korea-locked-down`
- `apple-money-count`
- `nyc-paris-flight`
- `goonvpn-youtube-spot`
- Attributes each block to [Stronkter](https://x.com/Stronkter).
- Stores and renders the original source prompt for each generated catalog page.
- Adds a local realistic map plate for the North Korea block so rendering does not depend on live map tile requests.
- Extends registry item metadata/schema with `authorUrl` and `sourcePrompt`.
- Updates catalog page generation to read items from `registry/registry.json`, keeping generated docs aligned to the public registry manifest.
- Ignores normal browser media preload `net::ERR_ABORTED` request failures for media assets during `hyperframes validate`, while preserving failures for real missing assets.
## Root cause
The imported projects are Catalog-ready compositions, but the registry/docs pipeline did not have first-class source-prompt or linked-author fields to expose creator credit on generated MDX pages. The audio-backed compositions also surfaced a validation edge case: Chrome can report aborted media preload requests as `net::ERR_ABORTED` even when the audio file exists and playback is valid.
## Verification
### Local
- `bun run --filter @hyperframes/cli test src/commands/validate.test.ts`
- `bun run --filter @hyperframes/core test src/registry/types.test.ts`
- `bun run sync-schemas:check`
- `bunx oxlint packages/cli/src/commands/validate.ts packages/cli/src/commands/validate.test.ts packages/core/src/registry/types.ts packages/core/src/registry/types.test.ts scripts/generate-catalog-pages.ts`
- `bunx oxfmt --check ...` on changed source, registry, docs, and composition files
- `git diff --check`
- `bun packages/cli/src/cli.ts lint` and `validate` against temp installed projects for all four blocks
- Lefthook pre-commit: lint/format/typecheck on the initial commit, plus format on the amend
- Lefthook commit-msg: commitlint
### Browser
- Exercised all four blocks through HyperFrames preview routes with `agent-browser`.
- Captured playback screenshots and WebM recordings for:
- `north-korea-locked-down`
- `apple-money-count`
- `nyc-paris-flight`
- `goonvpn-youtube-spot`
## Notes
- The zip also contained unrelated project directories, but this PR intentionally includes only the four prompt-matched Catalog blocks requested here.
- The imported one-shot compositions may trigger the existing large-composition lint warning, but there are no lint errors and runtime validation passes.
