 SQLite FTS5 storage, Tree-sitter symbols and references, hybrid ranking, graph
 impact analysis, token-budgeted retrieval packets, optional local embeddings,
 hooks/watch support, multi-CLI installation, MCP server support, and a tested
 GitHub-only `pipx` install path.
 
-The `1.4.0` release hardens the MCP contract (a `schema_version` + `tool`

+The `1.5.0` release turns the dependency graph into a navigable map: every edge
+carries a `confidence` audit trail (`extracted`/`inferred`/`ambiguous`, surfaced
+in `refs`/`impact`); a new zero-dependency analytics pass computes modules
+(communities), god nodes, and surprising cross-module links, exposed via the
+`architecture` command/MCP tool; `path` traces the shortest dependency chain

+graph is coloured by module and sized by connectivity, with `--format
