+# Taiwan: the 1973 treatment amendment and the 1992 rewrite
+
+Research checked on 26 October 2026. Read `DATA-MAINTENANCE.md` and
+`WRITING.md`, the Taiwan profile and its nine history entries before editing.
+No book was used. This pass fills the 1970s and 1990s of the 1955–1998 gap
+with two dated entries and one article. Cameroon and the other active
+country passes were left untouched.
+
+## Sources actually read
+
+- Wikisource 戡亂時期肅清煙毒條例 (民國44年): the 1955 original, in full —
+  Article 4's one-month self-report window, Articles 5/7/9/10/14 penalty
+  structure (cannabis sale death-or-life, use 1–3 years, possession
+  6 months–2 years), martial-law purpose.
+- Wikisource 戡亂時期肅清煙毒條例 (民國62年): the 1973 revision, in full —
+  legislated 12 June, promulgated 21 June 1973, amending Articles 4 and 9.
+  Article 4 reopened treatment-before-discovery without the one-month limit;
+  Article 9's use ranges are textually identical to 1955 apart from
+  rewording, including treatment-first, the two-thirds aggravator and the
+  third-offence death penalty.
+- Wikisource 肅清煙毒條例 (1992 revision): the current-page text, in full —
+  legislated 3 July, promulgated 27 July 1992, renaming to the Narcotics
+  Elimination Act. Purpose de-martial-lawed; Article 4 treatment exits
+  widened (designated centres, non-addict surrender); death penalties
+  softened to death-or-life in Articles 5, 9 and 14; fines redenominated in
+  New Taiwan dollars; cannabis use and possession ranges unchanged;
+  observation detention and sentence credit added.
+- MOJ legislative history (English): the amendment list confirming the
+  1973 Articles 4/9 amendment, the 1992 renaming and amended articles, and
+  the 1998 full revision. Used only as an index, not for content.
+
+## What changed
+
+- New `taiwan-voluntary-treatment-1973` (1973-06-21, easing, unscored):
+  the reopened treatment exemption; penalties unchanged so no segment
+  moves. Fills the 1970s.
+- New `taiwan-narcotics-revision-1992` (1992-07-27, `other`, unscored):
+  the de-martial-lawed rewrite with wider treatment exits and softened
+  death penalties; cannabis ranges unchanged so no segment moves. Fills
+  the 1990s.
+- `taiwan-narcotics-act-rewritten-1998`: related link to the 1992 entry.
+  No scores touched — both new entries are scoreless context, and the
+  timeline's single scored step (1955 100→2) is unchanged, so the profile
+  file was not edited.
+
+## Article
+
+- `articles/taiwan-narcotics-revision-1992.md` (369 words, four headings):
+  the purpose rewrite, treatment exits, softened deaths, sentence-credit
+  mechanics, and the bridge to 1998. Links to `/country/tw/`.
+
+## Still open
+
+- The exact promulgation-day gazette citations for 1973 and 1992 (dates
+  rest on the statutes' own legislative/promulgation lines, which is
+  standard for this file).
+- Whether the 蔴煙 reading bears on the 1955 scores; out of scope here.
+
+## Validation
+
+- Parsed-history comparison of the working tree against HEAD: exactly two
+  entries added and one entry revised (related link); no other country's
+  entries changed, none removed.
+- `node scripts/data-status.cjs chain tw`: single scored step, no flags.
+  `npm run scores:triage -- tw`: no open items from this pass (both new
+  entries carry `unscored` reasons; the 2009 entry was already reviewed).
+- `npm run history:test`: 39 passed. `npm run answers:test`: 27 passed.
+  `npm run scores:triage -- tw`: 1 scored, 0 open.
+- Production build passed (4,222 pages). Both new history pages render.
+  Article: 369 words, four headings.
+- Concurrent agents' work in shared files is untouched; this commit stages
+  only the Taiwan hunks and files.
