Named contractors — who was named, by whom, and denied (computed registry).

Honest 'detective work': catalog the NAMING + its provenance, do NOT assert custody. TIER 1 (documented role in REAL work): Bigelow Aerospace/BAASS held the ONLY documented UAP contract ($22M AAWSAP/DIA 2008-10) and delivered 38 DIRDs + Skinwalker fieldwork -- PAPERS, not craft; Lockheed Skunk Works ran documented black aerospace (U-2/SR-71/F-117); Battelle authored Blue Book Special Report 14 (the Roswell 'memory metal' link is disputed lore); EG&G/Bechtel/Honeywell are documented Area-51/NTS/Sandia support; Global Marine built the Glomar Explorer for Project AZORIAN (a terrestrial recovery). TIER 2 (named in allegations, denied/untested): the 2026 Burlison congressional interrogatories formally NAMED and probed MITRE, Aerospace Corp, Lockheed, Northrop Grumman, Raytheon/RTX, Boeing, General Dynamics, SAIC/Leidos, Battelle, Booz Allen, BAE and Bigelow for UAP records (documented that they were named; the custody hypothesis is untested; MITRE moved to comply); the Lockheed 'may have housed materials' pointer is Harry Reid's SECONDHAND claim with no corporate confirmation; Peraton (Picatinny theory) and the TTSA metamaterials acquisition are alleged. VERDICT: the one company with a real UAP contract produced papers; every custody naming is secondhand, a hypothesis, or a records demand (a probe, not a finding); AARO located the named entities and found the named programs 'do not exist; are misidentified authentic, highly sensitive national security programs; or resolve to a disestablished program', and the named companies denied it. So: we can name who has been NAMED and tier each -- we cannot name a company that verifiably holds non-human craft, because no evidence supports it. Sibling to the crash-retrieval provenance, apparatus-map, and secrecy analyses.
