• fix(sentinel): treat the getLeaderSchedule error -32022, which Agave 4.4 returns for an identity with no slots in the epoch, as not scheduled, like the empty schedule earlier versions return. Against 4.4 RPC nodes, access requests with backup IDs failed on every poll and were never granted, and a primary with no slots failed instead of being rejected.
• migrate to Solana 3.0: workspace solana-* crates and solana-sdk move to the 3.0 line, solana-program-test to 3.0.12, and the doublezero SDK git-deps repin from client/v0.27.1 to the #3830 merge revision (malbeclabs/infra#1853)
• release artifact now builds as a static x86_64-unknown-linux-musl binary (malbeclabs/infra#1853)
• TLS for HTTP clients moves from openssl to rustls; trust roots are the bundled webpki Mozilla set plus the host OS certificate store, so OS-installed private CAs remain trusted (malbeclabs/infra#1853)
• chore(contributor-rewards): bump doublezero client to v0.27.1 (#388)
• fix(sentinel): adapt to SetAccessPassArgs API change after doublezero dep bump
