The download page's module checklist showed every documented module, whatever version was selected. About 90 of the ~800 entries aren't in 11.43.0: mostly long-removed adapters (aol, districtm, spotx, ...), plus modules removed in 11.0. Selecting one only produced a build without it. This makes the checklist show only the modules in the selected Prebid.js version.

How it works

• When the version list loads, and whenever the selected version changes (including from an uploaded config), the page fetches that version's file list from jsDelivr (data.jsdelivr.com/v1/packages/npm/prebid.js@<version>?structure=flat). Module names are taken from modules/<name>.(js|ts) and modules/<name>/index.(js|ts). Checklist entries whose moduleCode isn't in the list are hidden.
• A status line above the bidder list says how many modules are shown, e.g. "Showing the 718 modules available in Prebid.js 11.43.0".
• Checked boxes are kept. A hidden module stays checked, so switching back to a version that has it restores it. Hidden modules are left out of the download and listed in the existing "removed from your download" alert, alongside the min_js_version check.
• Pending state: while the selected version's list is loading, the download button is disabled, so a build can't be generated with the previous version's filter applied.
• Fallback: if the listing can't be loaded, all modules are shown, as before, and the status line says so. Failed lookups aren't cached, so the next selection retries.
• Cost: published versions are immutable, so each listing is fetched at most once per page view and cached by the browser for a year (jsDelivr sends max-age=31536000). It's about 440 KB compressed per selected version.

Docs naming fixes

15 pages had a download moduleCode that didn't match any module file. Those modules were silently missing from builds, and with this change they'd be hidden. Their front matter is corrected:

• Analytics modulecode: browsi, byData, datawrkz, im, liveIntent, nexx360, AsteriobidPbm.
• Module module_code: dynamicAdBoostRtdProvider, humansecurityRtdProvider, humansecurityMalvDefenseRtdProvider, agenticAudienceRtdProvider.
• User ID useridmodule: adriverIdSystem, jixieIdSystem.
• Bidder pages SMB and synapsehx get a filename: override (smbBidAdapter, synapsehxBidAdapter); their biddercode is unchanged.

Touching those analytics pages also meant fixing their existing markdownlint errors (heading levels, one code fence language).

Testing

Tested in headless Chrome against the live download page, with this download.js swapped in, the status line injected, and the versions service mocked (it's currently down, see #6839). Requests to jsDelivr were real:

	Status line	rubiconBidAdapter	aolBidAdapter (removed long ago)	paapi (removed in 11.0)
11.43.0 selected	"Showing the 718 modules available in Prebid.js 11.43.0."	shown	hidden	hidden
10.29.2 selected	"Showing the 666 modules available in Prebid.js 10.29.2."	shown	hidden	shown
jsDelivr response delayed 3s	"Checking which modules…", download button disabled until it loads (initial load and version switch)
jsDelivr unreachable	"Couldn't check which modules are available…, so all modules are shown."	shown	shown	shown

This edits assets/js/download.js in different places from #6842, so the two shouldn't conflict.
