-Two seeds per task, 26 of each:
-
-- **`figures/convergence/`** — the root's running estimate after each continuation, with a
-  ±1 s.e. band. The band assumes independent draws; a tree's are not, since simulations
-  share prefixes, so it is honest about when an estimate has settled and optimistic as a
-  confidence interval.
-- **`figures/trees/`** — the whole search tree, each node filled by its subtree value on a
-  red→yellow→green ramp and ringed if it ended.
+Two seeds per task — 26 of each, as SVG under `figures/` and as PNG under `figures/png/`.
+
+### The root's value, as the evidence arrives
+
+The running estimate of `V(root)` after each of the 48 continuations, with a ±1 s.e. band.
+The band assumes independent draws; a tree's are not, since simulations share prefixes — so
+it is honest about when an estimate has settled and optimistic as a confidence interval.
+
+A task the policy is good at, and one it is not:

+
+The estimate is noisy for the first handful of continuations and settles by roughly twenty —
+which is what the budget of 48 was chosen against.
+
+### The search tree, valued
+
+Every node filled by its subtree value on a red→yellow→green ramp, sized by the endings
+behind that value, and ringed if it ended. The ring is the tier; the fill is the value.

+
+The shape is the point: progressive widening spends the budget near the root, so the tree is
+wide and shallow — 8 children at depth 1, 40 at depth 2 — and each of those runs out to the
+horizon as a spine of nodes that share one value until the ending that set it.
