unverified: no trust signals recorded yet

A demand-sensing live-music discovery directory built on the Vertical Directory engine, fed by the Ticketmaster/Marquee feed, that captures visitor interest as a graph to decide which venue sites to build next.

Live Music Tonight

livemusictonight.com is a Vertical Directory (one host row routed by includes/vd-router.php → includes/vertical-directory.php). It is not a bespoke page — it reuses the VD engine. It started empty because vdFetchEvents() read the unpopulated dynamic_section_cache; it now sources real shows.

Data resolution (here-and-now first)

Live music is a NOW thing, so the homepage leads with location + Tonight and lets the visitor expand outward in time and space.

• Located (explicit ?lat&lng from the geolocate button, or approximate from

Cloudflare CF-IPLatitude/Longitude): live Ticketmaster geo feed via marqueeTmFetch() (gained latlong/radius/unit/endDateTime/sort), closest first. If nothing falls in the radius/window, an empty state nudges widening — it never silently dumps far-away national events on a located visitor.

• No location: stored marquee_events, then a live national fallback so the page is

never blank. This is the browse mode where search/filter belongs (future).

• Radius filter: 5 / 10 / 25 / 50 / 100 miles, default 5. Auto-requests precise

location on first load (remembers a denial via sessionStorage, no nagging).

Time windows (30-day horizon)

vdWindowEnd() hard-caps everything at +30 days (no stray next-year listings). Tonight is here-and-now; This Week / This Month are calendar-bounded; Next 7 Days / Next 30 Days roll forward from today regardless of the date. The nav exposes the rolling options via dropdowns on This Week / This Month.

The interest graph (the point)

Every Interested and Tickets click records a demand signal to lmt_interest (?ajax=lmt_interest, ip-hash rate-limited) keyed to venue identity + genre + area. This is OUR derived demand signal, not a mirror of Ticketmaster's catalog (ToS-clean). Admin → Marquee → "Live Music Demand" ranks venues by interest (interested×3 + ticket×5) and hands a venue to the build flow. So real demand decides which venue sites Prospector and the Cloud Factory build next — the flywheel applied to events.

Ecosystem ties

• Cross-ecosystem identity: the user avatar renders in the VD

header (magic-link sign-in), so Interested can tie to a real person.

• Photos: TM event images render as card thumbnails (music-note SVG placeholder otherwise).
• Icons follow the house rule — crafted inline SVGs, never emoji/clipart.
• Venue cross-link by ID: Marquee stamps Ticketmaster's tm_venue_id onto the

businesses row when it builds a venue site (marqueeStampVenueId), so _vdLinkVenues links a live event to its Doozer site deterministically (businesses.tm_venue_id = event.tm_venue_id) instead of fuzzy name matching. This is the durable handle a venue's own business site can use to point back at LMT or any vertical directory.

• Interested on business sites: each event on a venue's Doozer site (rendered by

renderBusinessEventsSection) carries an Interested button (internal bookmark via lmt_interest) beside Tickets and + Calendar — the network keeps the save instead of pushing people to an external calendar.

Marquee is venue discovery, not an event log

The Marquee admin (marqueeRecentVenues) surfaces ONE row per distinct venue (keyed by tm_venue_id, else name+city+state), NEW venues (no Doozer site) first, built ones marked. The product is finding businesses to build through the live event feed — not listing events. Build acts on a representative event; the rest of the venue's shows become its site's calendar.

• Future: an "add all to calendar" iCal feed on my.doozer.cloud for a user's saved events +

gatherings; clicking a show could spin up a Gathering on GoHe.re (gated on the gatherings surfaces); non-ticketed/community shows union into the same feed.
