+# Research pass: Seychelles 1949 amending-ordinance article
+
+Research checked on 26 October 2026. The fully-cited Seychelles 1949
+entry gains a short properly-sourced article from the amending ordinance
+text itself (E/NL.1953/52, 3 pp., read in full). No entries, scores,
+profiles or timelines changed.
+
+## What was verified (all sources actually read)
+
+- UN E/NL.1953/52 (25 May 1953, via Digital Library file endpoint):
+  Seychelles Ordinance No. 35 of 1948, passed 29 December 1948,
+  published in Gazette No. 3 of 10 January 1949. Read: s. 15 amendments
+  to principal Ordinance No. 26 of 1935 — new paragraphs (j) desomorphine,
+  (k) pethidine, (l) non-external-use Indian-hemp extract/tincture
+  preparations, (m) amidone, (n) metopon; trimmed codeine/dionine
+  exceptions in (h)/(i); morphine-ester and ecgonine additions.
+- New `articles/seychelles-cannabis-extract-preparations-1949.md` (~250w
+  body, 4 sections, single law source). The entry
+  `seychelles-cannabis-extract-preparations-1949` is untouched: its
+  per-sentence citations already cover the same facts.
+
+Claim boundaries: the article's "same formula Britain was circulating to
+its colonies" is grounded in the identical non-external-use wording read
+in the Barbados 1951, St Vincent 1947 and Cyprus 1948 filings this
+session — cited to the Seychelles text itself, which carries the
+identical formula. No penalty/enforcement claims (the ordinance makes
+none).
+
+## Verification and files
+
+- No changes.yaml edit in this batch (article only); YAML untouched.
+- `npm run build`, `npm run history:test`, `npm run answers:test` green;

+  citation marks checked.
+- Commit limited to own work: the new article and this note, via
+  pathspec. Foreign staged/worktree files excluded and preserved.
