brainblast v0.7.2 — Deployment Intelligence

Deployment Intelligence — a new brainblast deploy-plan [dir] command that answers the two questions every Anchor builder works out by hand before anchor deploy: how much SOL do I need? and what's the exact ordered transaction sequence?

How much SOL do I need?

From the compiled .so under target/deploy/, modeled on the on-chain BPF upgradeable loader:

Item	Formula	Recoverable?
Program account	rent(36)	❌ until program closed
Program data (2× upgrade headroom)	rent(45 + 2·len)	❌ until program closed
Buffer (transient)	rent(37 + len)	✅ refunded at deploy
Init PDAs (treasury, config, …)	rent(space) each	depends on close logic
Transaction fees	base fee × (buffer + writes + deploy + inits)	❌ spent

Reports a wallet funding figure (safe upper bound) and the steady-state lockup.

Exact transaction sequence

Create buffer → write program chunks → deploy → one initialize step per #[derive(Accounts)] struct, each annotated with the rent it locks/refunds and its fee.

Notable

• Anchor init parsing (tree-sitter-rust) extracts space, seeds, and payer per init / init_if_needed account.
• Non-literal space (e.g. 8 + State::INIT_SPACE) is flagged and excluded from totals rather than guessed.
• --program-len BYTES models an uncompiled build; --max-len-mult N overrides the 2× headroom; --json emits the full plan for an agent.
• New /brainblast-deploy-plan slash command. 20 new tests (368 total green).

Also refreshed stale version + bundled-rule-count references (now 16 bundled rules incl. the 3 Anchor program-security checks).
