feat(goals): derive the Goal artifact lifecycle projection

 historical progress does not establish that current direction materials were read.
 
+Status also exposes a separate `run_history.goals[].artifact_lifecycle` readout
+and Markdown summary: observed phase, evidence milestones, guards and next steps.
+It consumes the current Goal's session-runtime work observation before display
+trimming. Outstanding required work keeps the phase `qualifying` even when
+Todos are complete and historical progress is reached. An absent work observation
+does not invent a work requirement. This v0 readout **never recommends a terminal
+transition**: `closing` stays a verification step with the machine-readable
+`next_transitions[].reason_codes` value `acceptance_unverified`, both when sources
+are missing and when all bounded sources were observed. Consumers use that code,
+not English `precondition` text. A Goal already recorded as terminal still displays
+`lifecycle_phase: closed` with no next transitions. Adding acceptance-driven
+terminal advice requires a separate contract change and producer-side validation.
+This readout grants no execution or completion authority; the Dashboard card
+above keeps its separate acceptance-observation contract.
+
+Work observation coverage follows the supplied projection, not `adapter.kind`:
+
+| Source delivered to status | Work observation coverage |
+| --- | --- |
+| Session-runtime adapter, or another adapter emitting the same session-runtime projection | Available only with `session_runtime_readonly_projection_v0`, a matching Goal id, and work facts |
+| Adapter without that projection, or a projection with a mismatched schema/Goal id | Unavailable; this readout does not query quota or other lane owners |
+
+Without that source a Goal may read `closing` from Todo/history even when a lane
+outside the observation still requires work. Neither `closing` nor absence of
+`work_lane_selected` proves all work is complete; the lane and completion owners
+retain their decisions.

+
+缺少该来源时，即使观察范围外仍有必须执行的工作，Todo/历史也可能让 Goal 显示 `closing`。
