v4.3.1 - Checksum Stability Fix

This patch release fixes a regression introduced in v4.3.0 that caused checksum drift when upgrading from v4.2.0.

Bug Fix

Checksum drift after upgrade (#414): Fixed regression where upgrading from v4.2.0 to v4.3.0 caused:

• V-scripts showing "Script checksum has drifted" warnings
• R-scripts unexpectedly re-executing on first deploy

Root cause: The trailing comment fix in v4.3.0 modified script content before checksum computation.

Solution: Implemented two-phase rendering where checksums are computed on user content, and Snowflake-specific transformations are applied only at execution time.

Upgrade Path

| From | To | Impact | |------|-----|--------| | v4.2.0 | v4.3.1 | ✅ Seamless - no unexpected script execution | | v4.3.0 | v4.3.1 | R-scripts with trailing comments may execute once (reverting to original checksum) |
