These gaps are why the critical path is broker verification, not availability. Each row is something public sources genuinely do not publish.
gapGenerator backup — published at ZERO of 87 candidates (landlord work-letter / tenant-capex negotiation everywhere)
gapHVAC lab exhaust / make-up air modifiability — published at ZERO listings (TI scope, not spec-sheet items)
gap24/7 building access — published at ZERO listings
gapOvernight / carrier restrictions — published at ZERO listings
gapFloor plans — not available online for any shortlisted property
gapRate transparency — withheld/contact for pricing on majority of EC-core candidates (16203 Park Row, 16155 Park Row, 1304 Langham Creek, 16223, 16820 Barker Springs)
gapPower amperage/phase unpublished on every EC-core candidate except 7310 West Rd (480V/3ph/400A) and 15720-15740 Park Row (480V 3-phase)
