Qualify wait states in the coordination graph (CUST-WP-0074-T04)

Task nodes carry wait_kind (external | human | both | unqualified, null
unless wait): the hub field wins, otherwise derived from needs_human and
dependency edges (task-level depends_on, or a workplan dependency row whose
target the task cites). Workplan nodes carry blocked_kind (human | external
| none, null unless blocked). Task-level depends_on becomes a task ->
workplan/task depends_on edge; depends_on edges carry edge_kind commitment
(cyan #0891b2), human gates are marked on the node (humanGate, rose
#be123c). A needs_human=true query / "Needs human" toggle / --needs-human
flag keeps only blocked_kind=human workplans and their human-wait tasks;
the parameter survives in the shareable URL and mode switch like
include_residuals. Fabric stays a read of State Hub.

+## Qualified waits (CUST-WP-0074)
+
+Open task nodes carry `wait_kind` (`external` | `human` | `both` |
+`unqualified`, null unless `status: wait`). The hub's `wait_kind` field wins
+when present; otherwise `needs_human: true` → `human`, a dependency edge
+(task-level `depends_on`, or a workplan dependency row whose target the task
+cites) → `external`, both → `both`, neither → `unqualified`. Workplan nodes
+carry `blocked_kind` (`human` when any wait task is a human gate, else
+`external`, else `none`; null unless `status: blocked`).
+
+Task-level `depends_on` becomes a task → workplan/task `depends_on` edge
+(`edgeSource: task`). All `depends_on` edges carry `edge_kind: commitment`
+(cyan `#0891b2`); citation edges carry `edge_kind: citation`. Human gates have
+no edge target, so the marker is on the node: `humanGate: true`, rose
+`#be123c` (`WAIT_KIND_COLORS` in `coordination_graph.py`).
+
+The **Needs human** checkbox / `needs_human=true` query (CLI `--needs-human`)
+keeps only `blocked_kind: human` workplans and their human-wait tasks — the
+operator's queue. It survives in the shareable URL like `include_residuals`.
