The only gathered source discusses idempotency keys in payment systems and does not address non-custodial browser session keys or any of the related security tradeoffs. Therefore, none of the sub-claims can be supported.
Sub-claim "Non-custodial browser session keys reduce the risk of large-…": 0% covered — No gathered content addresses non-custodial session keys, central server credential theft, or user-side secure storage.
Sub-claim "Using short-lived session keys limits the window of opportun…": 0% covered — No gathered content discusses short-lived session keys, attack windows, or re-authentication tradeoffs.
Sub-claim "Browser-based storage of session keys is susceptible to cros…": 0% covered — No gathered content addresses XSS risks or network transmission of long-term secrets in relation to browser session keys.
Sub-claim "Non-custodial session keys eliminate the need for a trusted …": 0% covered — No gathered content discusses trusted third parties, key loss, or recovery mechanisms for non-custodial session keys.
All gathered sources are irrelevant to the sub-claims about non-custodial browser session keys, and the skipped sources also do not appear to address this topic. Therefore, purchasing additional sources would not improve coverage.

Evidence ledger — quotes verified before rewards
Non-custodial browser session keys reduce the risk of large-scale credential theft from central servers, but shift the burden of secure key storage to the user.
0%No reward-qualifying evidence
Using short-lived session keys limits the window of opportunity for an attacker who compromises a session, but requires frequent re-authentication that may inconvenience users.
0%No reward-qualifying evidence
Browser-based storage of session keys is susceptible to cross-site scripting (XSS) attacks, but avoids transmitting long-term secrets over the network.
0%No reward-qualifying evidence
Non-custodial session keys eliminate the need for a trusted third party to hold secrets, but if a user loses their key, they lose access without any recovery mechanism.
