A platform or emulator record whose value designates a collection
file carries its sha1 and is filed under the file's other hashes, so
a SHA1 paste finds the setups listing it by MD5. The data page shows
every manifest field, writes URL templates as code, states the EmuDeck
rule, the browser lookup and the empty lists. systems.json gives every
id holding files a page, Files to source splits at 100 rows with an
upload link per file, and MiSTer and BizHawk get no empty core table.
Platform pages link each reader's source line at its pinned revision, name the collection file that serves each entry, show launcher records with their lines, name systems with the id beside them and the list they were read from in words. The largest system lists move to pages of their own so a platform page stays under 500 KB.
Gaps: plain numbers with a bar, a badge only for missing required firmware, Files to source as a heading. Cross-reference: counts per platform, one page per platform, one row per upstream project. Exports: gaps listed once, status, category and the serving file in the CSVs and SQLite, the commit in each API envelope, the provenance Wanted list as CSV. Catalog dates in words on the provenance page.
