+A [Jersey gap pass](research/history-jersey-gap-2026-10-26.md) on 26 October
+2026 fills the longest modern gap in the history (1954 to 2018). Six entries
+from the enacted Jersey laws add the 1965 cultivation ban, the 1966 possession
+and supply order, the 1971 cannabinol listing, the 1978 law as it took full
+effect in 1980, and the 1998 and 2015 Parish Hall caution guidance. The 1954

+rebuilt in stages (100→97→70→12→14→16→19) instead of one drop at 1954, the
+2019 medical order now carries its access step, and the unchecked 2024

+# Jersey, 1955 to 1998: filling the 64-year gap
+
+Research checked on 26 October 2026. Read `DATA-MAINTENANCE.md` and
+`WRITING.md`, the Jersey profile and its eight history entries before editing.
+No book was used. Jersey had the longest modern gap in the history: no entry
+between the 1954 dangerous drugs law and the 2018 medical-prescribing vote.
+This pass adds six entries, gives the 2019 medical order the score step it was
+missing, verifies the one unchecked Jersey entry (the 2024 Centenier fines),
+re-dates and rewrites the 1954 entry, and writes two articles. Cameroon was
+left to another agent; nothing outside Jersey was touched.
+
+## Sources actually read
+
+Jersey Law refuses plain fetches (it returns a block page), so the enacted
+PDFs were read through Wayback copies of the same `jerseylaw.je` addresses,
+then extracted with `pdftotext`. What was read in full:
+
+- Dangerous Drugs (Jersey) Law, 1954 (L.5/1954): arrangement, Articles 1–4
+  (Part I: raw opium, coca leaves, Indian hemp and resin preparations;
+  import/export only under licence, through St Helier or the airport),
+  Article 3 (Committee power to control production, possession, sale and
+  distribution by order), Article 10 (extracts and tinctures of Indian hemp
+  in Part III), Article 14(2) (fine up to £1,000, ten years, or both, plus
+  forfeiture), Article 21 (repeal of the Loi passed 1 October 1923 and
+  confirmed 19 December 1923) and Article 22 (commencement by appointed day).
+- Dangerous Drugs (Jersey) Law, 1954 (Commencement) Act, 1954 (R&O 3503):
+  the law came into force on 1 January 1955; repeal of four named provisions
+  of the 1923 Loi waited until 1 January 1957.
+- Dangerous Drugs (Amendment) (Jersey) Law, 1965 (L.17/1965): Article 2
+  (Indian hemp becomes cannabis and cannabis resin), Article 7 (occupier
+  permitting premises for smoking or dealing) and Article 8 (knowing
+  cultivation except under licence). Sanctioned 18 September 1965,
+  registered 5 November 1965; the law has no separate commencement article,
+  so the entry is dated by year only.
+- Dangerous Drugs (General Provisions) (Jersey) Order, 1966 (R&O 4779):
+  Articles 1–4 (supply, procuring, advertising and possession of cannabis
+  other than extracts and tinctures, except as authorised or licensed;
+  general authority for practitioners, veterinary surgeons, authorised
+  sellers of poisons and hospital pharmacists), Article 12 (authorised
+  sellers may still make and dispense extracts and tinctures), and
+  Article 32 (made 18 April 1966, in force 1 May 1966).
+- Misuse of Drugs (Jersey) Law, 1978 (L.10/1978): Second Schedule Part II
+  (cannabis and cannabis resin, Class B), cannabinol in Class A, Fourth
+  Schedule penalties (Class B possession five years, supply and intent
+  fourteen) and Fifth Schedule repeals (1954, 1965, 1964 and 1972 laws).
+- Misuse of Drugs (Jersey) Law, 1978 (Appointed Day) (No. 2) Act, 1980
+  (R&O 6797): everything not already in force came into force on
+  1 May 1980. The endnotes of the consolidated law record the first
+  appointed day (Articles 2 and 30 and Schedule 1, 1 January 1979,
+  R&O 6603); only the 1980 date is used in the entry.
+- Crime (Public Order) (Jersey) Law 2024 (L.9/2024): Article 13(3) inserting
+  Article 28A into the 1978 law (Centenier level 1 fine for Class B/C
+  possession accepted by the person charged); adopted 7 February 2024,
+  registered 11 October, in force 18 October 2024.
+- Attorney General's Directive 1/2015 letter and Centenier Written Caution
+  Guidelines (gov.je, read through Wayback): the 2015 directive replaces
+  the 1998 guidance; the guidelines set cannabis at up to 15 g, Class B,
+  for a written caution.
+- Cannevi, *Cannabis Prohibition in Jersey* (read in full as text): the
+  1923 Loi's opium-and-cocaine focus, the Home Office letter of
+  30 January 1939 calling it "much out of date", the 1971 modification
+  order's schedule text, and the 1980 designation order. Cross-checked
+  against End Cannabis Prohibition Jersey, *Legal Status of Cannabis in
+  Jersey* v1.4 (11 December 2025, read in full), whose timeline agrees on
+  1954/55, 1965, 1966, 1971, 1978/80, 1998 and 2015.
+
+Search snippets were leads only. The 1971 order's own PDF (R&O 5492) is not
+in the Wayback Machine, so the 1971 entry rests on the two read secondary
+accounts that reproduce its schedule; it is a context entry.
+
+## What changed
+
+- `jersey-dangerous-drugs-law-1954` keeps its id but is now dated
+  1955-01-01, the commencement the old entry skipped in favour of the
+  sanction date (13 April 1954). Its old description claimed the law
+  "controlled the import, export, production and sale" of Indian hemp;
+  the text controls import and export directly and only empowers orders
+  for the rest. Rewritten, with the repeal of the 1923 Loi stated.
+- New scored steps: 1965 cultivation and premises offences, the
+  1 May 1966 possession and supply ban (the large drop), the 1998
+  Attorney General caution directive, and the 2019 medical order, which
+  previously had no `before` although it is the step behind today's
+  access score.
+- New context entries: the 1971 cannabinol listing, the 1978 law as it
+  took full effect on 1 May 1980 (mixed: possession maximum fell from ten
+  years to five while supply rose to fourteen, so `other` with an
+  `unscored` reason), and the 2015 caution guidelines (wider amount, same
+  handling, so `unscored`).
+- `jersey-centenier-drug-fines-2024` was the last unchecked Jersey entry.
+  The 2024 law was read; the entry is now `checked: true` with the
+  commencement date and a locator.
+- `jersey-local-medical-prescribing-2020` got an `unscored` reason (first
+  local clinic, not the legal step), clearing Jersey's score triage.
+
+## Score handling
+
+The old chain dropped 100 to 16 in one step at 1954 and credited the 1955
+position with today's access score. The rebuilt chain is:
+
+1955 100→97 (border licensing only) · 1965 97→70 (growing and smoking
+premises) · 1966 70→12 (possession and supply) · 1998 12→14 (Parish Hall
+caution) · 2019 14→16 (medical access 1→3) · 2024 16→19 (today).
+
+Access is 1, not 0, after 1966 because authorised sellers of poisons could
+still make and dispense cannabis extracts and tinctures. Today's profile
+scores did not change, so the profile file was not edited. `data-status
+chain je` reports no flagged step; `scores:triage je` reports no open
+entry. Silent decades fall from six (1960s–2000s except the 2010s) to
+none between the 1950s and the 2020s.
+
+## Articles
+
+- `articles/jersey-possession-ban-1966.md` (the 58-point drop).
+- `articles/jersey-dangerous-drugs-law-1954.md` (the first restriction).
+
+Both follow `WRITING.md`: 350–500 words, plain headings, per-source
+citations, links to the neighbouring entries and `/country/je/`. No
+picture: no openly licensed image shows the subject itself.
+
+## Still open
+
+- The 1923 Loi's text is not online (a government FOI answer says the same),
+  so its lack of a cannabis offence rests on Cannevi's research and the
+  1954 law's structure, not on the Loi itself.
+- The 1965 law's exact commencement day: the entry uses the year.
+- Parish Hall practice before 1998 (police annual reports quoted by
+  Cannevi were not opened) and the 2019 second-offence extension and 2022
+  consolidated guidance, which would extend the caution story.
+- Guernsey's first loi is dated 1931 by Cannevi and 1934 by the legal-status
+  paper; that disagreement was noted and not used anywhere.
+
+## Validation
+
+- Parsed-history comparison against the pre-edit snapshot
+  (`/tmp/je-base/changes-before.yaml`): exactly six entries added and four
+  Jersey entries changed (1954 rewrite, 2019 `before`, 2024
+  checked/citations, 2020 `unscored`); no other country's entries changed,
+  none removed. Total history 3,159 → 3,165 entries.
+- `node scripts/data-status.cjs chain je`: no flagged steps;
+  `npm run scores:triage -- je`: 0 open entries.
+- `npm run history:test`: 38 passed. `npm run answers:test`: 16 passed.
+- Production build passed (4,160 pages). The two new article pages and
+  `/country/je/` were spot-checked in `dist/`: titles, dates, score steps
+  and reference lists render.
+- Articles checked at 361 and 353 words, three headings each, every
+  citation mark naming a listed source.
+- The other agent's Cameroon commit (`dd17a4e`) landed during this pass;
+  its remaining uncommitted `source-archive.json` work was left untouched
+  and is not part of this commit.
