brainblast v0.7.4 — Live On-Chain Intelligence

Answers, from live RPC, two questions Solana devs otherwise work out by hand on Solscan.

Is the upgrade authority a multisig? (extends trust-graph)

The RPC probe already resolved the authority address but could only mark it unknown. It now reads the authority account's owner program to classify it:

Owner program	Verdict
System Program	⚠️ single-key (one key can replace the program)
Squads	🔐 multisig
SPL Governance (Realms)	🏛 dao
anything else	❓ unknown — owner recorded, never a false single-key

The renderer shows the classifying owner and an at-a-glance Trust line per program: authority · verified build · audited.

Is the oracle fresh? (brainblast oracle <account>)

A provider-agnostic freshness gate — instead of parsing each oracle's binary layout, it measures the universal signal: the slot of the most recent transaction touching the account vs. the current slot.

• Reports FRESH / STALE / NO_HISTORY with slots/seconds behind.
• --max-staleness-slots N / --max-staleness-seconds N (default 150 slots ≈ 60s).
• Exit 1 on STALE or NO_HISTORY — drop it in front of any pricing path. --json for agents.

Works for Pyth, Switchboard, Chainlink, or any account whose freshness means "written recently."

Also

• Classification fails safe: a wrong/missing owner id degrades to unknown, never a false single-key.
• New /brainblast-oracle slash command; programmatic exports (classifyUpgradeAuthority, checkOracleFreshness, …). 20 new tests (407 total green).
