The Vietnamese competitive-programming pipeline — anchored on the specialised-school informatics (chuyên Tin) track and culminating in consistent IOI medals — operates on a two-layer canon: the MOET-published Tài liệu giáo khoa chuyên Tin (three-volume series edited by Hồ Sĩ Đàm, last substantively revised in 2010–2011) and the communitymaintained VNOI wiki (wiki.vnoi.info), which functions as the de facto living syllabus. We are aware of no prior Vietnamese peerreviewed work that maps this canon against an international reference (search protocol in §1.4). This paper presents the first systematic crosswalk between the Vietnamese chuyên Tin canon and the current public IOI Syllabus 1, yielding a 68row coverage matrix coded on a four-tier depth scale across three Vietnamese corpora. Three structural findings follow: (i) an approximately 15-year refresh lag in the MOET textbook line against the post-2010 additions to the IOI canon; (ii) a dependency-ordering inversion in which the VN canon places dynamic programming and graph algorithms before Fenwick trees and segment trees, opposite to Laaksonen; (iii) a scaffolding gap where approximately 15 Syllabus topics reside on VNOI wiki only, without worked-example pedagogy or problem-progression curation. We characterise the VN pipeline as a gifted-teacherplus-gifted-wiki substrate without a maintained textbook bridge, and identify the editorial gap as the dominant constraint on a scaffolded Vietnamese-language contemporary canon.
