Module facade 

TasksFacade - the seam between the task MCP tools and workspace state. The production impl (ProdTasksFacade) resolves the caller’s project and drives the direct Workspace task methods; the mock records calls for tool tests.

Task-list mutations are direct Workspace methods (lock the tasks mutex + persist), NOT Command-bus dispatches - a task is workspace state, like the cron list beside it, not a session action.

Structs

ProdTasksFacade 🔒

Production facade over Weak<Workspace> (weak to avoid a cycle with the MCP server the workspace owns).

RemovedTaskTree 🔒

The tree a tasks__delete removed: the named task as it stood, and how many descendants went with it.

TaskDraft 🔒

A task as tasks__create states it: the fields the caller supplies, before the project, the id and the timestamps are stamped on.

TaskLinkDraft 🔒

One link as a caller states it: the kind is derived from the target’s shape when it is not given.

TaskPatch 🔒

The fields tasks__update may change. An absent field is left alone.

Enums

TasksError 🔒

Why a tasks__* call failed.

Traits

TasksFacade 🔒

The task tools’ view of the workspace. Sync - task-list mutations are direct state writes with no async handler to await.

Functions

missing_task_error 🔒

The refusal for a stated id that names nothing in the caller’s project: an id another project owns is named as such, so a caller cannot read “no such task” as proof the row was never there.

narrow_rows 🔒

The list’s narrowing, one definition for the real path and the mock: owner by label, parent by id, status by state, ready by the board’s own mark.

resolve_parent 🔒

The parent a write stores: the row a stated id names when it lands on one, the words as stated when it names nothing (a child may point at a row that is gone), and a refusal naming the rows when it names several.
