+# Triage: Ivory Coast 1988 and Grenada 1979 closed as reviewed
+
+Research checked on 26 October 2026. Read `DATA-MAINTENANCE.md` (triage and
+timeline rules), both entries with their profiles and timelines before
+editing. No web search was needed: both decisions rest on the entries'
+already-checked sources and the current profiles. Two open triage items
+closed with `unscored` reasons; no scores, profiles or timelines changed.
+
+## What changed
+
+- `ivory-coast-drug-law-1988` (1988-07-22, tightening): `unscored` —
+  Law 88-686 was the punitive regime the scored 2022 law replaced (the
+  profile contrasts the one-to-five-year mandatory terms with the new
+  one-to-three-month treatment option); no independent segment movement.
+- `grenada-clampdown-1979` (1979, tightening): `unscored` — enforcement
+  campaign under the existing prohibition; no legal change and no segment
+  movement.
+
+Triage now reports CI and GD at 0 open (CI: 1916 100→9, 2022 9→11;
+GD: 1925 estimate 100→11, 2026 11→39).
+
+## Validation and tree note
+
+- Chains `ci` and `gd`: unchanged, 0 flagged steps.
+- `npm run history:test`: 40 pass, 0 fail. `npm run answers:test`: 40
+  pass, 0 fail. Production build: 4,364 pages, complete.
+- Commit stages only the two `unscored` hunks plus this note, via patch
+  filtering. Foreign work in the shared tree is excluded and preserved.
