 - 2026-06-16: Converted retiring `list_unique/list_sort/list_some/list_every/list_find` free functions to `StringList` methods, updated callers and method docs; full host gate passed: `Summary: 353 passed, 0 failed, 0 skipped`.
 - 2026-06-16: Added live examples across types, string, regex, time, markup, noise, uri, and session area pages; full host gate passed: `Summary: 353 passed, 0 failed, 0 skipped`.
 - 2026-06-16: Added `:example` blocks to all remaining doc pages, removed full PHP/JS Related Concepts filler, removed duplicate content code fences except resource-bound pages; full host gate passed: `Summary: 353 passed, 0 failed, 0 skipped`.
+- 2026-07-20: Marked the finished plan historical so it no longer presents completed work or one-off execution rules as current instructions.
