A green check next to any KEZ that controls a proven account. Unlike
Twitter's "we say so," the badge means YOUR browser independently
verified ≥1 of the peer's published proofs against the channel.
Server:
• handles.proofs column (JSON array of claim subjects) + ALTER for
existing DBs. Returned in /v1/u/:handle and /v1/by-primary as
`proofs` — pure discovery; peers verify each themselves.
• PUT /v1/profile/:handle/proofs (authed X-KEZ-Auth, signed over
"PUT\n/v1/profile/<h>/proofs\n<ts>", distinct line from inbox/stream
so sigs can't cross-replay; 60s skew; max 64 subjects).
• All 20 existing http tests still pass.
Client:
• api.ts: HandleResponse.proofs + setProofs() (signs + PUTs).
• verify.ts: verifySubject(subject, primary) — runs the real channel
verifier given just subject+primary (no local envelope needed).
• conversations-store: cache verified + verified_checked_at per peer.
• Messages: on conversation open, fetch the peer's proof subjects and
verify them in the background (24h cache → snappy, rate-limit
friendly). VerifiedBadge in the conversation row + thread header.
• Identity: reverify now publishes your verified subjects to your
profile (so peers can discover them) + shows the badge on your own
card.
• VerifiedBadge.svelte: scalloped-seal check in verified-green
(distinct from the cyan brand accent).
Flow: you reverify your proofs on Identity → they publish to your
profile → when someone opens a chat with you, their client fetches +
verifies them → you get the check on their screen.
