+# Azerbaijan: the 1974 possession step
+
+Research checked on 26 October 2026. Read `DATA-MAINTENANCE.md` and
+`WRITING.md`, the Azerbaijan profile and its timeline before editing. No
+book was used. This pass adds the scored 1974 Soviet possession step on
+the Baltic convention. The 2001 reform already has a peer article, which
+this pass leaves untouched (checked first this time). Cameroon and the
+other active country passes were left untouched.
+
+## Sources actually read
+
+- Wikipedia, Drug policy of the Soviet Union, in full: the 1974 decree
+  criminalised possession without intent to sell (up to three years) and
+  raised production and trafficking to ten to fifteen years.
+- The Meganorm reprint of the 22 June 1987 edict No. 7226-XI, in Russian
+  (edict header; amended Article 6 on first small-quantity possession).
+- The English translation of Azerbaijan's 2000 Code of Administrative
+  Offences (WHO extranet PDF): Article 68-1 personal-use
+  production/purchase/storage/transport/use (fine of 300–400 manats or 15
+  days' arrest; voluntary surrender exempts) and Article 123-1
+  sowing/growing/gathering in personal-needs amounts (fine of 10–15
+  manats).
+- Wikipedia, Cannabis in Azerbaijan, lede: illicit cultivation in the
+  south; medieval medical-text references (background only).
+
+Deliberately not done: no new article (the peer's 2001 piece covers the
+checked entry in depth, including the current Article 208 and criminal
+Article 237); no changes to any checked entry. The 1974 step's `after`
+state is forced by the checked 2001 `before` ({1,0,2,1,1,0}): unlike the
+Baltic inserts, cultivation moves 1→0 here, attributed to the edict's
+ten-to-fifteen-year production range. AzSSR-code text remains open
+archival work.
+
+## What changed
+
+- New `azerbaijan-soviet-possession-crime-1974` (1974, tightening,
+  scored, `before` {3,1,3,1,3,0}): union possession criminalisation with
+  the production-range clause, 20→9.
+- Final chain: 1934 100→20, 1974 20→9, 2001 9→14. Today's profile scores
+  are unchanged, so the profile file was not edited.
+
+## Validation
+
+- `node scripts/data-status.cjs chain az`: three steps, 0 flagged.
+  `npm run scores:triage -- az`: 3 scored, 0 open.
+- `npm run history:test` and `npm run answers:test`: all pass.
+- Production build passes; the new history page renders.
+- Concurrent agents' work in shared files is untouched; this commit stages
+  only the Azerbaijan hunks and files.
