+# Bangladesh's 1990–2018 amendment gap
+
+Reviewed 26 October 2026. Reread DATA-MAINTENANCE.md's source, date and
+score-chain rules, WRITING.md and the earlier Bangladesh research note.
+BOOKS.md's local-source/citation rules had been read in the preceding batch;
+no book is used here. This pass follows the earlier note's specific open lead
+that the cultivation, use and treatment insertions belong to the 2000
+amendment rather than the original 1990 law.
+
+## Sources actually read
+
+Downloaded the [official historical consolidation of the 1990 Act](https://bdlaws.minlaw.gov.bd/act-print-736.html)
+with curl after web requests timed out. Parsed the Bengali HTML locally and
+read the substantive sections with their amendment footnotes:
+
+- Section 9(3), especially notes 16–18: authorised pharmaceutical use,
+  treatment and scientific research; cultivation added to the licensed
+  activities; a permit for applying/using and a pass for movement.
+- Section 13: prescribing controls, including director-general authorisation
+  for prescribing drugs in Classes A and B. No assertion of a functioning
+  cannabis patient-supply programme is made from these legal powers.
+- Section 15 and note 23: government counselling, treatment and rehabilitation
+  centres, licensed private centres, and power to designate government or
+  prison hospitals as treatment centres.
+- Sections 19(3A)–(3B) and note 32: separate use penalties by class and a court's
+  power, considering the offence's seriousness, to order treatment in addition
+  to or instead of the punishment. The old Act's classes are not inferred
+  from the later 2018 classification: the article states the generic class
+  bands without assigning herbal cannabis a class not established here.
+- Definition of controlled delivery, section 42A and note 45: written
+  government authorisation, suspected offending and an evidential purpose,
+  authorisations of no more than three months at a time, and the supervised
+  movement of suspicious consignments. The notes attribute these changes to
+  Act 39 of 2000.
+- Section 42B and note 46, inserted by Act 32 of 2002: fifteen working days
+  where someone is caught in the act, sixty in other cases, a reasoned
+  seven-working-day extension, written reporting and transfer to another
+  officer. The replacement officer has seven or thirty working days;
+  failures require reporting within twenty-four hours. The authority can
+  record incompetence/misconduct in the annual confidential report and
+  take action under service rules if it attributes delay to the officer.
+
+The amendment years are directly established by the official footnotes. The
+original 2000 and 2002 amending Gazette texts and their commencement clauses
+were not recovered. Events therefore retain **year-only legislative dates**;
+no exact day or claim to a particular commencement date is supplied. The
+published rules are checked against the actual substantive consolidated text,
+not copied from a search summary. This does not represent the consolidation
+as an unamended original 1990 text.
+
+Downloaded the actual [UNODC precursor-training manual's Section Four](https://www.unodc.org/pdf/india/publications/precursor_Training_Manual/07_sectionfour.pdf).
+A web request returned 404, but curl successfully retrieved the 56-page PDF.
+Its text layer is empty. Read-only PDFKit/Vision OCR located the Bangladesh
+passage, then the actual page image was rendered and visually inspected:
+**printed p. 88, PDF p. 32**. It expressly attributes introduction of
+controlled delivery to the 2000 amendment and explains its identification
+purpose. Only that passage is cited; the remaining manual is not claimed as
+read. The PDF creation date is not treated as a publication date, and an
+unverified publication year is omitted from its citation. Research files,
+selected extraction and the rendered page remain local in
+`tmp/history-bangladesh-amendments-2026-10-26/`.
+
+UN meeting-record search results were leads, but the actual records could not
+be opened in this pass and are not cited. Uganda's unrecovered original 1970
+narcotics provisions were also rechecked as a candidate gap; the already read
+post-repeal consolidation did not recover them, so no new claim was added.
+
+## Changes and score scope
+
+Two checked events and two articles cover the 2000 treatment/licensing and
+controlled-delivery amendment, then the 2002 investigation deadlines. The
+1990 event receives related links to them; its substantive account is preserved.
+Both new entries are classified `other` with explicit unscored explanations.
+The first combines treatment, licensed professional/research activities and
+an enforcement technique within continuing prohibition. The second changes
+investigation procedure and officer accountability. Neither supplies evidence
+of an established cannabis treatment-supply programme or a whole-segment change.
+
+Every existing before-vector and the current country file are preserved. This
+batch does not verify the inherited enforcement allocation, the 2018 score
+transition, the modern medical-access position or the 2026 digital offence.
+Those require their own joint review of the original laws and current profile.
+The new articles use the 1990 penalty table as background, distinguish the old
+Act from today's law, and do not invent arrest outcomes or promise release
+when an investigation misses a deadline.
+
+## Validation
+
+Strict comparison checks two additions, only related-link additions to the
+1990 record, all existing score vectors and the byte-identical country profile.
+The articles have 358 and 379 words, three and four headed sections, complete source use
+and valid numbered citations and history links. All 39 history tests and 16
+answer/profile tests pass. Production-build and rendered/browser results follow
+after verification. Concurrent source-archive staging and edits are preserved.
+
+Final checks: production build passed with **4,203 pages**. Rendered validation
+confirmed both articles, unique numbered-reference targets, internal history
+links, the 2000s page, both additions in the JSON export and the unchanged
+current score of 3. The in-app browser confirmed the country chart's new context
+entries, all 21 country-history entries, the filtered Bangladesh history listing
+and the treatment article's statutory and UNODC references. The temporary preview
+and generated site output are removed after verification; local research and logs
+are retained. The commit excludes concurrently staged source-archive changes.
+
+Concurrent Eswatini edits appeared during the final live-checkout comparison.
+A fresh candidate based on HEAD plus only this batch's three event blocks and
+maintenance paragraph is verified separately. An isolated Git index excludes
+those edits and preserves unrelated source-archive staging; the working tree's
+concurrent changes are retained.
