+### Tests
+- **C-70 test adds** (#195): the share-**proportionality law** (the method's defining
+  forecast-proportion property, previously pinned only by the frozen-oracle fixtures); an mmap
+  **read-only pin** (`writeable is False`, in-place write raises); the reconcile
+  missing-`(time, priogrid_gid)`-mapping-entry raise.
+
+### Documentation
+- **C-70 docs refresh** (#196): `CLAUDE.md` rewritten for the released three-package reality;
+  README banner → v1.8.0 + chronicle; ADR-013 as-built amendment (`feature_names`); CIC accuracy
+  fixes (§5 artifact names → `values.npy`, PredictionFrame §6 real dtype behavior, index §6
+  NaN-via-dtype, Reconcile §10 pinning files); CICs/ADRs README framing refreshed; and a
+  **recurrence guard** — `validate_docs.sh` now checks the README banner's MAJOR.MINOR against
+  `pyproject.toml`.
