Changelog — mini-app-core

All notable changes to the mini-app-core crate are documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

mini-app-core is the transport-agnostic DB / schema / store / materialize library extracted from the mini-app-mcp workspace. The companion mini-app-mcp crate (binary, MCP stdio transport) depends on this library via a strict one-way mcp → core dependency boundary — mini-app-core carries zero rmcp dependency.

[0.1.0] - 2026-06-14

Added

• Initial release. Library extracted from mini-app-mcp v0.10.0 via workspace split so that other consumers (Tauri desktop apps, in-process DB embedders, the upcoming persona-network primitive) can use the core CRUD layer without going through MCP stdio transport.
• Public modules: schema, error, config, store, filter, materialize, dump, backup, snapshot, registry.
• MiniAppError enum with structured error codes (codes::*) covering 26 failure modes (validation / not-found / schema / storage / config / table / batch / materialize / alias / ambiguous-id).
• Store — SQLite-backed row store with tokio::task::spawn_blocking for all blocking I/O, RFC 7396 shallow-merge update mode, and UUID prefix matching for get / update / delete.
• TableRegistry — atomic multi-table registry backed by arc-swap::ArcSwap for lock-free hot reload.
• materialize::do_materialize — row selection + field projection + multi-format filesystem output with SHA-256 integrity digest.
• backup / snapshot — SQLite online backup utilities with retention.
• ListFilter — serde-tagged enum (Eq / In / Or / And / Like) with schema-validated field filtering and recursive composition.

Notes

• impl From<MiniAppError> for rmcp::ErrorData is intentionally NOT provided by this crate (Rust orphan rule, RFC 1023). MCP wire conversion lives in the mini-app-mcp crate as a pub(crate) fn miniapp_error_to_mcp_error ACL adapter (Outline rust book §5-1-10 K-orphan-rule pattern).
