Six tasks. Task 1 is deliberately large because the model change is atomic
under TypeScript: Post.standingRule -> Post.rules will not compile as a partial
change, so everything referencing it moves together, with the settings UI
getting only a read-only summary until Task 5.
Self-review closed two spec requirements that had no test: a version dated
before the fold start is legal but inert, and an archived post still resolves
its rules because it still folds.
