What it says

No type in cairn_atproto holds an access or refresh token: the session state has DIDs, handles, service URLs, request ids and the app's calls; SessionInfo has no token field and its decoder never reads accessJwt or refreshJwt (SessionInfo.ofJson_replaceTokens). Tokens go from the host's capture to the Keychain and back as a request's secret header (Cairn's Request.http). By construction; checked by this package's make fake-fuzz (atproto.no-token), which runs the session against the fake PDS and its host and searches every Lean value for the fake's token markers.

Evidence

assumedStated, not proved. The proofs rely on it.
fuzzedNot shown yet: the trusted-base fuzzer's check atproto.no-token held. A CI step will publish it (#95).
