The 5-10s RPCs that broke calling were not cold-start — they were
per-RPC sequential rqlite reads, each forwarded to a raft leader that
geography-blind election had placed on a 256ms-distant node.
Lever A (serverless): cache function metadata + env vars in-process
(5s TTL, invalidated on deploy/enable/disable/delete) and stop the hot
invoke path re-fetching the function for the authorization check —
removes ~820ms of leader-routed pre-flight reads from every op.
Lever B (namespace): a locality-aware leadership reconciler hands raft
leadership off a geographically-isolated namespace leader to the nearest
co-located voter, via rqlite's transfer-leadership API. All nodes stay
voters — membership, quorum and fault tolerance are unchanged. Cuts the
per-hop cost from ~274ms to ~20ms when a distant node had become leader.
- Introduce `BatchQueryConsistency` with `ReadConsistencyNone` to allow
local SQLite reads, bypassing leader round-trips for performance.
- Add `function_invoke_async` host function to support non-blocking
fire-and-forget function execution.
- Integrate PubSubDispatcher to enable libp2p subscription for trigger patterns
- Add BatchQuery to rqlite client to reduce round-trips for multi-query operations
- Implement lifecycle management for dispatcher and add safety limits for batch queries
- Change RQLite consistency level from `none` to `weak` to ensure reads
route to the leader and prevent stale data reads (fixes#235)
- Add `normalizeColumnKey` to allow snake_case SQL columns to map to
CamelCase Go struct fields automatically (fixes#65)
- Add comprehensive unit tests for DSN generation and column mapping
- Add `contract.go` to manage and validate embedded SQL migrations
- Introduce `AssertSchema` to verify database version at startup
- Include `SchemaMismatchError` with actionable recovery instructions
- Add comprehensive unit tests for version parsing and validation
- Add migrations for per-namespace publish sequences and persistent WebSocket function settings
- Integrate PersistentWSManager and WSBridge into the gateway dependency graph
- Upgrade serverless engine to use a multi-tier rate limiter
- Update JWT claims to support custom application-defined fields
- Replace CLI-based rootwallet calls with agent-based communication
- Update production provisioner to support sudo-based service management
- Add API key-to-wallet resolution for gateway operator handlers
