YQL-20804: Fix Decimal type conversion

2026-07-15T11:10:17Z

#### `YQL-20804`: Fix Decimal type conversion ✎ - Enhanced type annotation system to properly handle Decimal type conversions by introducing a new `EDecimalConversionMode` configuration option that allows controlling how common types are computed for Decimal values - Modified core type annotation functions to accept and utilize a `TTypeAnnotationContext` parameter, ensuring consistent type resolution across join operations and type conversions - Updated join-related functions and peephole optimizations to pass type context information, fixing issues with Decimal type compatibility during join key processing - Added comprehensive unit tests to verify Decimal type conversion behavior and ensure proper casting between different Decimal precisions and scales - Extended type annotation infrastructure to support both strict and lenient Decimal conversion modes, improving error handling and type inference for edge cases Autodescription by Yandex Code Assistant commit_hash:f4ec01ad79cb2f3219b529118380747828075e6b

YQL-21307: Suppress invalid application on PartialTypeCheck

2026-06-30T12:41:42Z

Added the `ExpandApplyUniversal` pass for partial type annotation. A binding can be resolved to a lambda during a full typecheck, but during a partial typecheck, a module resolver is limited and can return a universal value. A series of the `ExpandApply` applications can lead to some arguments being discarded, e.g. `(Apply (lambda '(a b) a) X Y)` discards `Y` during a full typecheck, but not partial, so arguments at `(Apply (InstanceOf (UniversalType)) X Y)` are type checked, and so partial type check had a greater recall. commit_hash:7573df489129be47aa66d74d0f4b96086166c3ba

YQL-21321 deep error check for EnsurePersistable

2026-06-16T18:49:43Z

#### Deep error checking for EnsurePersistable ✎ - Replaced shallow error checking with comprehensive error detection in `EnsurePersistable` functions to ensure all type annotation errors are properly identified - Introduced new `HasAnyError` function that performs thorough error traversal to catch nested or indirect type errors - Updated test cases to verify error handling behavior and ensure proper error reporting for incompatible types in SQL operations - Enhanced type annotation validation to provide more reliable persistence checks for expression nodes Autodescription by Yandex Code Assistant commit_hash:019e5924e7d6bdfea7fa46be3da3615b17727b76
