+Institut Louis Malardé now have separate research entries, checked against an
+official retrospective account. The recorded 1925-estimate-to-2023 gap falls from
+98 to 53 calendar years. Earlier restrictions and precise commencement remain
+unresolved; no score or profile change. The original preamble supplies new 1924,

+# French Polynesia: the 1978 framework and research exceptions
+
+Research date: 26 October 2026. Read `docs/DATA-MAINTENANCE.md`, `docs/WRITING.md`
+and the local-book research guidance before this pass.
+
+## Gap and changes
+
+The largest interval in the existing post-1800 French Polynesia timeline ran from
+its unresolved 1925 first-restriction estimate to the January 2023 medical-law entry:
+98 calendar years. Adding the 1978 adoption reduces that recorded interval to 53
+calendar years, with a further 44-year interval to the 2022 research permission.
+These are distances between recorded events, not proof of uninterrupted legal regimes.
+
+Added three checked, unscored events and one 396-word article:
+
+- `french-polynesia-cannabis-prohibition-adopted-1978`: 18 August adoption;
+- `french-polynesia-research-possession-permission-2022`: 30 March authorisation;
+- `french-polynesia-research-cultivation-permission-2023`: 9 March authorisation.
+
+The research events are culture/science context entries. They give one institute
+specific permissions and establish no ordinary patient or adult access. The first
+restriction estimate, country profile and all scores remain unchanged.
+
+## Primary text recovered and read
+
+The pharmacists' professional council links to Lexpol's record for deliberation
+78-137. That index incorrectly displays 13 August; the gazette and Lexpol's own
+record establish 18 August. Lexpol failed in the web reader but downloaded directly.
+
+- Record: https://lexpol.cloud.pf/LexpolAfficheTexte.php?texte=201417
+- Original gazette: https://lexpol.cloud.pf/document.php?document=189651&deb=861&fin=870
+- JOPF 28, 15 September 1978, pp.861–870 (ten PDF pages).
+- Read preamble, executable order, articles 1, 17–18, 21–24, 41–43, 65–67;
+  visually checked printed pp.861, 863, 866 and 870 against the scan.
+
+Article 18 prohibits import/export, production, commerce, use and possession of
+Indian hemp and preparations; its botanical definition refers to female flowering
+and fruiting tops. Its research exception requires a government-council order on
+the public-health director's proposal. Article 42 in the original medical chapter
+already prohibits THC isomers and derivatives, with a research exception. This
+claim is therefore not inferred backwards from the 2024 consolidation. Article 66
+requires destruction of cannabis seized over an article-18 offence.
+
+The date is explicitly **adoption**, not asserted commencement: 18 August adoption,
+4 September executable order, 15 September publication. Lexpol's earliest available
+consolidated version is dated 15 September. Neither an adoption nor an executable
+order alone proves when each prohibition first became enforceable against a person.
+No new score step is inferred from this sequence.
+
+## Later official accounts
+
+- Assembly health-committee report, distributed 28 October 2022:
+  https://www.assemblee.pf/travaux/downloadTexte/1555822
+  Read report pp.2–4, especially the account of existing restrictions, absence of
+  therapeutic/hemp exceptions and reasons for a replacement framework.
+- Competition Authority opinion 2024-AO-01, 31 January 2024:
+  https://autorite-concurrence.pf/wp-content/uploads/2024/02/Avis-n2024-AO-01-du-31-janvier-2024-Cannasbis-V.Def_.pdf
+  Read printed pp.4–5, paragraphs 15–27 and footnotes; visually checked p.5.
+  Footnote 10 identifies presidential orders 248 PR (30 March 2022, possession)
+  and 196 PR (9 March 2023, possession and cultivation). Paragraphs 25–27 describe
+  police samples, imported varieties, controlled containers and later results.
+  The source is a retrospective official account; no exact date is assigned to
+  sample handovers, planting or findings. The description attributes results to
+  January 2024 rather than treating them as achieved on the authorisation date.
+
+## Other documents checked and limits
+
+Downloaded and extracted UN E/NL.1987/21–23 (five pages), circulated 5 April 1989:
+https://digitallibrary.un.org/record/75150/files/e-nl-1987-21-23-f.pdf
+The preambles on pp.2–3 corroborate the 4 September 1978 executable order. Their
+operative changes concern other drugs, so no cannabis event was added for 1986.
+
+Also recovered the original order 953 S of 15 December 1978 and its medical
+schedule: https://lexpol.cloud.pf/document.php?document=189683&deb=489&fin=493
+Lexpol record: https://lexpol.cloud.pf/LexpolAfficheTexte.php?texte=197722
+The scan is JOPF 21 NS of **8 June 1979**, pp.489–493, with cannabis/resin on
+p.491 and THC later in the tables. Read the order and relevant schedule passages.
+Its signature/executable date and later publication differ; no effective-date
+claim or separate cannabis scheduling step was inferred.
+
+An attempted Institut Louis Malardé 2022 annual-report PDF URL returned HTML,
+so its indexed snippet supplies no checked claim or public citation here.
+
+## Remaining larger-gap leads
+
+The 1978 preamble names the **4 January 1924** decree regulating poisonous
+substances in the French Establishments in Oceania, a 19 April 1926 pharmacy
+decree, a 9 November 1937 substances decree, the 1954/1955 extension of health
+legislation (local promulgation 30 September 1955), and the 1970 drug law (local
+promulgation order 407 AA, 5 February 1971). These are primary-text leads, not
+proof that the 1924 decree was the first cannabis restriction. Recover their
+original schedules, amendments and local publication before replacing the estimate.
+The 1924 and 1937 instruments are the best next leads for the remaining 53-year gap.
+
+## Validation
+
+History scope tests: 40 passed. French Polynesia score-chain audit: zero flags,
+unchanged 100 → 11 estimated first step. Full isolated Astro build and generated
+page/citation checks are recorded in the batch's ignored temporary directory.
