Editing Module talk:InfoboxImage (section)

===Feedback===
A couple of things to note:
* <code><nowiki>mw.loadData</nowiki></code> already caches the data load once per module load (see [https://www.mediawiki.org/wiki/Extension:Scribunto/Lua_reference_manual#mw.loadData]), so there's no need for the new code at sandbox lines 23-26.
* Remember that Lua parsing/interpreting time is significant. Thus when you have a long list of data (as in [[Module:InfoboxImage/data]]), it's innately O(n), because the parser has to touch every element anyway.

Because of these, my preference is to perform mw.loadData locally within each function. This performs lazy evaluation of loadData -- it's not loaded until its needed. For this module, the lazy load occurs 100% of the time, so it isn't critical at this time. But if someone changes the code in the future, lazy loading could be helpful. If you always load the module at lines 23-26, then you'll always incur the Lua parsing overhead for the data.

The conversion of [[Module:InfoboxImage/data]] to use a hash table directly is nice, although won't help performance.  Because the time is dominated by Lua parsing, the conversion of the list to a hash (which only happens once one module load) will not be noticable.

Also: please don't remove comments from the code. They're helpful for future developers.

:Thank you for the excellent feedback, [[User:Hike395|hike395]]. You make a very sharp point regarding the Scribunto environment mechanics and the overhead of Lua parsing time versus execution loops. I have fully updated the sandboxes to incorporate your suggestions, balancing the structural improvements with the engine's best practices:
:* '''Lazy Loading Implemented:''' I removed the module-level eager loading of the data submodule. The call to <code>mw.loadData('Module:InfoboxImage/data/sandbox')</code> has been moved locally inside <code>trackingCat</code> and <code>i.IsPlaceholder</code>. This ensures that the data layer is only processed when actually needed, preventing unnecessary overhead if the module's scope changes in the future.
:* '''Comments and Assertions Restored:''' All documentation comments and essential logical descriptions have been added back to ensure readability and maintainability for future developers.
:* '''Hash Table & Bug Fix Retained:''' The data submodule structure remains as a direct lookup hash table (which, as you noted, provides a cleaner and more native design even if parsing time dominates), and the critical fix for the bypassed alt-text validation keyword filter is intact.

:The [[Module:InfoboxImage/sandbox]] and [[Module:InfoboxImage/data/sandbox]] are now fully aligned with both performance optimization and proper lazy-evaluation architecture. If there are no further objections, I will proceed with the official Edit Request.
