1//! MCP tool surface for trusty-memory.
2//!
3//! Why: Concentrates the public tool contract in one file so changes are
4//! auditable and the MCP schema stays in sync with the implementation.
5//! What: Defines `MemoryMcpServer`, `tool_definitions()` (the MCP
6//! `tools/list` payload), and the in-process tool dispatcher wired to the
7//! real `PalaceRegistry` + retrieval / KG APIs.
8//! Test: `cargo test -p trusty-memory-mcp` validates the schema and dispatch.
9//!
10//! Tools exposed:
11//! - `memory_remember(palace, text, room?, tags?)` -> drawer_id
12//! - `memory_recall(palace, query, top_k?)`        -> Vec<Drawer> (L0+L1+L2)
13//! - `memory_recall_deep(palace, query, top_k?)`   -> Vec<Drawer> (L3 deep)
14//! - `memory_list(palace, room?, tag?, limit?)`    -> Vec<Drawer>
15//! - `memory_forget(palace, drawer_id)`            -> ()
16//! - `palace_create(name, description?)`           -> PalaceId
17//! - `palace_list()`                                -> Vec<PalaceId>
18//! - `palace_info(palace)`                          -> palace metadata + stats
19//! - `kg_assert(palace, subject, predicate, object, confidence?, provenance?)` -> ()
20//! - `kg_query(palace, subject)`                    -> Vec<Triple>

72/// Dispatch a tool call by name to its real handler.
73///
74/// Why: Centralises the name → handler mapping; every handler now performs a
75/// real read/write against the live `PalaceRegistry` instead of returning a
76/// stub. After issue #227 the body is a thin router — every tool's logic
77/// lives in its own `handle_*` function above so the dispatcher itself is
78/// auditable at a glance.
79/// What: Returns `Ok(Value)` on success, `Err` on unknown tool / bad args /
80/// underlying failure.
81/// Test: `dispatch_palace_create_persists`, `dispatch_remember_then_recall`,
82/// `dispatch_kg_assert_then_query`, `dispatch_unknown_tool_errors`.
