vecshift 1.1.0

New features

• classify_employment_status() gains an unemployment_duration_threshold parameter as a convenience shortcut to override rules$unemployment$duration_threshold without constructing a full custom rule set.

Robustness

• vecshift(), classify_employment_status(), and merge_consecutive_employment() now return correctly typed empty results when called on zero-row inputs instead of failing.
• Error messages from vecshift(), process_employment_pipeline(), merge_original_columns(), and merge_overlapping_values() now include remediation hints, the offending column class, and (where appropriate) the list of available columns.

Performance

• add_unemployment_periods() defers its internal copy() until ordering must be mutated, and uses .I-based indexing instead of .SD[1] / .SD[.N] to extract the first and last record per person.

Internal

• Extracted the repeated extra-column type detection block in merge_consecutive_employment.R into the internal helper .classify_extra_columns().

vecshift 1.0.5

Performance

• Optimized vecshift() core and merge_consecutive_employment() for ~25% faster processing
• Resolved all test failures in classify_employment_status and test suite

vecshift 1.0.4

Bug Fixes

• Fixed critical bug in add_external_events() that caused “storage mode of IDate is somehow no longer integer” errors when mixing Date and IDate objects. Added explicit IDate conversions in .prepare_events_data() and .create_synthetic_unemployment() helper functions to ensure consistent date type handling throughout the pipeline. (#PR)
