- Platform::contentOverflow returns int (0 = fits) via max(), drops the
nullable-int + ternary pattern; HasSocialHttpClient and the validation
rule updated to compare against 0 instead of null.
- Drop the hardcoded 63206-char limit to 10000 across all entry points
(Platform enum, MCP CreatePostTool/UpdatePostTool, FacebookRules, all
three FormRequests). Facebook's API accepts up to 63206 but nobody
writes 63k-char posts and emoji-heavy content risks overflowing the
TEXT column's 65535-byte ceiling.
- Compiled i18n JSON regenerated with the content_exceeds_platform key.
