📝 Walkthrough

Walkthrough

Adds _strip_ident_quotes() to unescape SQL double-quoted identifiers and updates _resolve_live_table() to resolve sql_table values against the introspected live tables map using multiple candidate names (qualified, bare, and unquoted variants). Unit tests cover both helpers. Package version is bumped to 0.7.5.

Changes

Schema drift: quoted identifier resolution

Layer / File(s)	Summary
_strip_ident_quotes and _resolve_live_table implementation slayer/engine/schema_drift.py	Adds _strip_ident_quotes(ident) to remove surrounding double quotes and unescape "" sequences. Extends _resolve_live_table() to build a candidate list of full qualified, bare table, and both unquoted variants before checking the live tables introspection map.
Unit tests for both helpers tests/test_validate_models.py	Imports both internal helpers for direct testing. TestStripIdentQuotes covers bare names, quoted identifiers, escaped inner quotes, unbalanced quotes, and whitespace. TestResolveLiveTable covers bare lookup, schema-qualified fallback, quoted parts, and the None path.
Version bump pyproject.toml	Updates project version from 0.7.4 to 0.7.5.

Poem

🐇 A quote here, a quote there,
Double "" floating in the air,
The schema lookup peeks inside,
Strips the wrapper, checks each side —
No table hides from this bunny's eye! 🔍
