-## Unreleased
-
-### Internal
-
-- Introduce a shared `DBCursor` Protocol (packages/special/types.py) and adopt it across special modules.
-- Add comprehensive type hints in core modules (special/, sqlcompleter, sqlexecute, key bindings, config, filepaths, lexer, completion_refresher).
-- Remove remaining `# mypy: ignore-errors` headers in special modules; reduce use of `Any`.
-- Tighten mypy configuration (target Python 3.9; disallow untyped/incomplete defs; no implicit Optional; warn on Any).
-- Remove references to “mycli” from comments and docs.
-- Minor refactors for clarity; ruff + mypy pass repo-wide.

-### Bug Fixes
-
-- Make `check_if_sqlitedotcommand` robust for non-string inputs.
