Simplicio Runtime v3.9.0

[3.9.0] - 2026-09-20

Desktop: deferred

Added

• MCP core catalogue (29 tools) with codegen, brain, plan, doctor, decide, prompt, deliver, diff, and execution_report. Default profile is core.
• Bounded Map-before-task plus background map preflight after daemon auto-spawn.
• Host-native Read/Write/Edit blocked on MCP profile core/full; Simplicio owns file I/O. Third-party MCP/plugins stay allowed.

Changed

• Retired public CLI verticals, messaging bots, and sk-/st- prefixes return unknown_command / via_exec.
• CI pins rustc 1.94.1; validate --repo smoke uses a tiny fixture with a 90s timeout.

Fixed

• sha2 0.11 / rand 0.10 / rusqlite compile so cargo build --bin simplicio links.
• Map cancel/budget (SIMPLICIO_MAP_BUDGET_MS), fail-closed cache, nonblocking flock, skip hashing too-large files.
• Doctor clears stale daemon.sock; simplicio update re-runs mcp register and hook sync.
• Cargo.lock records simplicio-agent-plane 3.9.0 so cargo --locked matches the workspace.

Fixed

• simplicio doctor clears a stale daemon.sock / daemon.pid pair when the recorded process is dead (#5766).
• simplicio update re-runs mcp register and hook sync after apply, with --no-mcp-sync / --no-hooks-sync opt-out (#5772).
