+# Senegal: closing the 1987, 1997 and 2007 triage items as reviewed
+
+Research checked on 26 October 2026. Read `DATA-MAINTENANCE.md` and
+`WRITING.md`, the Senegal profile and its timeline before editing. No book
+was used. This pass reviews the three open tightening entries against the
+primary French texts and records `unscored` reasons: all three move only
+trafficking-side or recodifying provisions while the cannabis personal-use
+bands stay in the light Article 109 range. No scores change. Cameroon and
+the other active country passes were left untouched.
+
+## Sources actually read
+
+- Law 97-18 of 1 December 1997 (Code des drogues, via the CILD site and
+  its Wayback PDF), in the operative parts: Article 8 prohibiting
+  cannabis cultivation; Articles 95–98 trafficking and facilitation
+  penalties at five to ten years; Article 109 (small-quantity purchase,
+  possession or cultivation for personal use: two months to one year plus
+  triple-value fine, covering high-risk plants including cannabis oil,
+  other cannabis-plant derivatives and lower-risk drugs, with exemption
+  for minors, first-timers and sworn undertakings); definitions tying
+  Tables I–IV to the UN conventions.
+- The CILD Code-des-drogues page (Wayback): the 2007 law revising
+  Articles 95–103 to ten to twenty years' forced labour (Article 99
+  personal-use supply at five to ten years; Article 100 Tableau III
+  personal-use supply at six months to two years); links to the 1997,
+  2007 and decree PDFs.
+- The DRI parliamentary file for Law 87-12 could not be re-read (the
+  cited dri.gouv.sn PDF returns an error page — link rot since the entry
+  was checked). The 1987 reason follows the checked entry's own text
+  (two-to-ten-year mandatory trafficking penalties expressly excluding
+  simple users) cross-checked against the 1997 Code's five-to-ten-year
+  trafficking bands.
+
+## What changed
+
+- `senegal-trafficking-amendment-adopted-1987`: `unscored` reason —
+  trafficking penalties expressly excluding simple users; cannabis user
+  bands unchanged.
+- `senegal-code-des-drogues-1997`: `unscored` reason — Code creation
+  with cannabis personal use in Article 109's light band; recodification,
+  no segment moves.
+- `senegal-trafficking-law-2007`: `unscored` reason — Articles 95–103
+  raised to ten-to-twenty-year forced labour; Article 109 untouched;
+  cannabis bands unchanged.
+- Triage now reports Senegal 1 scored, 0 open (was 3 open); open entries
+  overall fall 503→500. No article: a reasons-only pass with no scored
+  event.
+
+## Validation
+
+- `node scripts/data-status.cjs chain sn`: single 1916 step, 0 flagged.
+- `npm run history:test` and `npm run answers:test`: all pass.
+- Production build passes.
+- Concurrent agents' work in shared files is untouched; this commit stages
+  only the Senegal hunks and files.
