+
+First public release under MIT.
+
+- `replan()` returns one of four decisions: `proceed`, `pivot`, `stop` or
+  `hold`.
+- A plan with no recorded assumptions returns `hold`, never `proceed`.
+- An assumption with `observed: null` is NOT ASSESSED and blocks.
+- A broken assumption whose fallback has no `floor` makes the decision
+  `stop`.
+- Non-numeric values are never ordered lexically; `equals` works on any
+  value.
+- `toReport()` and `formatReplan()` produce an evidence-record report.
