rifty-goal

name	rifty-goal
description	Drive one rifty goal (epic) through its lifecycle — fit an outcome or legacy epic into a goal directory, pick up the next slice, re-chart the map after a merge, or close the finished goal. Invoke on a whole-epic hand-off, "fit/write up epic X", after a slice PR merges inside a goal, or when a goal's map is empty.

Owns transitions of ONE goal directory docs/backlog/epics/<slug>/ — shape: docs/backlog/README.md §Shape, template epics/TEMPLATE.md. Plan, don't build: every mode ends where implementation begins and resumes after merge. Review (rifty-review), the user interview (rifty-refine), unplanned defects (rifty-fix), and intake (rifty-to-backlog) are other actors — hand off, never inline their work.

Detect the mode from state; run exactly one mode per invocation:

State	Mode
No goal dir — a hand-off naming an outcome, or a legacy single-file epic	FIT
Ready goal with an open frontier (unblocked, unpicked children)	PICKUP
A slice of this goal just landed (Final+GREEN on the goal branch, or merge), or new facts arrived	RECHART
Map ## Items empty and invariants provable (fog lines disposition inside CLOSE)	CLOSE

Standing rules: a ready goal.md never changes (amend = CLOSE + fresh FIT); ledger.md only grows; map.md is yours to edit — but it is an index, not a store: one line + link, content lives on items and the ledger.
