= Drupal 11.3 Technical Note: Heritage Project Custom Tweaks =

== Overview ==
This document outlines the custom module created for the Heritage Project to handle specific user experience (UX) and data integrity requirements that are not met by core Drupal 11.3 configuration.

== Features ==
# '''Status Message Link Removal:''' Replaces the linked node title in "Saved" messages with plain text for Historians, preventing them from leaving their View.
# '''Date Format Validation:''' Enforces a `dd/mm/yyyy` format on all text fields ending in `_day` and performs a calendar sanity check (e.g., blocking Feb 31st).

== Implementation: heritage_tweaks.module ==
This code is stored in `web/modules/custom/heritage_tweaks/heritage_tweaks.module`.
