@inhuman.tools/plugin-tasks

Session notebook on the behavior surface, plus a project owner for promotion.

Module	Owner	Methods
behavior/session.scm	session	incomplete, create, page, start, drop, after, stamp, validate
behavior/project.scm	project	accept, accepted, complete
behavior/tools.scm	model ABI	task__create, task__start, task__drop, task__after, task__validate
behavior/foreground.scm	foreground bot	round-end recitation

create keeps the exam text only when it inspects the tree and names tasks/write-completion-verdict. validate proposes limbo and stamp proposes verdict. Both actions are host-sealed, so a plugin call cannot freeze the exam. Acceptance on the project owner is not completion. Rolling the session back does not retract that acceptance.

Recitation is the foreground hook's self/notify. An open page is activating, a pending-only notebook is ambient, and an empty notebook is silent.

The kernel installs this package as a default plugin, not as a builtin. behavior/tools.scm is loaded when the plugin is enabled. There is no JS tool or trajectory projection.
