Agent Bridge v0.3.0

Agent Bridge 0.3.0

Changed

• Replaced the mail backend with an in-house SQLite WAL engine and six scoped
  MCP tools. The installed package has no third-party runtime dependencies.
• Bound identity to the MCP connection, removing credentials and repeated
  project/agent arguments from model context.
• Made conflicting reservation batches atomic: conflicts grant no paths.
• Added idempotent sends, bounded inbox/body pagination, and explicit byte limits.
• Capped checkpoint notices at 1,536 UTF-8 bytes and suppressed unchanged notices.
• Added injected-byte counters without claiming tokenizer or billing savings.
• Added read-only legacy migration into a separate database and Linux pidfd
  process identity checks. Stop 0.2 services and sessions before upgrading.
• Shortened the README and separated architecture and operational documentation.

Added

• Concurrency, authentication, migration, retry and context-budget tests using
  an independent MCP client and temporary local state.
• Static type and documentation-policy gates, secret scanning, pinned CI actions,
  contributor and security policies, issue/PR templates, and the MIT license.
• A repeatable local benchmark for storage latency and protocol size.

Compatibility

• Linux with pidfd support is required; macOS is not supported by this version.
• Native sessions must be relaunched after upgrading. No live session is replaced
  automatically. Existing mail, worktrees and the original database are preserved.
• Public directory submissions remain separate from repository releases.
