 # ISO gaps
 
-ISO 9:1995 non-Russian Cyrillic — per-letter coverage check vs registry
-(scripts exist: maps/tools + docs/coverage diffs). ISO 259 Hebrew letter
-table (pointed input = Track B companion). ISO 7098 pinyin (large
-syllabary — the din chinese approach). ISO 15919 Indic remainder —
-enumerate the script set vs the 4 existing pli/san/hin? maps and encode
-the missing scripts.
+SOURCES STATUS (2026-11-03): only ISO-9-1995.pdf is in
+interscript-private-references/iso/. ISO 259, ISO 7098 and ISO 15919
+PDFs are NOT in the library — encoding them without the normative
+tables would violate the no-fabrication law. OWNER-GATED: acquire the
+three PDFs (or bless well-known secondary sources per table).

+- ISO 9:1995 non-Russian — ACTIONABLE (source present). Table 3 (118
+  non-Slavic characters, one sequence in Cyrillic alphabetic order) is
+  a scanned table; transcription in progress (map planned as
+  iso-mul-Cyrl-Latn-9-1995-t3 following the -t1/-t2 suffix convention).
+  Coverage check vs the registry happens on the transcribed pairs (the
+  Russian tables 1-2 are covered by iso-rus-Cyrl-Latn-9-1995).
+- ISO 259 Hebrew letter table (pointed input = Track B companion) —
+  BLOCKED on the source PDF.
+- ISO 7098 pinyin (large syllabary — encode with the DIN 32708 kana
+  approach) — BLOCKED on the source PDF.
+- ISO 15919 Indic remainder — the corpus has 18 iso-*-15919 maps
+  (asm ben guj hin inc kan mal mar nep ori pan pli x4 pra san tam tel).
+  The 15919 script set also covers Sinhala, Lao, Khmer, Tibetan and
+  per-script vowel extensions — BLOCKED on the source PDF; enumerate
+  precisely once acquired.

 Obtain current ICAO 9303 + UNGEGN romanization documents; diff each vs
 the registry's icao-*/un-* maps; encode genuine gaps, note reissues.
 The registry has icao-{rus,bel,bul,mkd,srp,ukr}-9303 + icao-mul-2015.

+SOURCE STATUS (2026-11-03): neither the current ICAO 9303 part
+documents nor the current UNGEGN romanization files are in
+interscript-private-references/. OWNER-GATED acquisition (the

+per-language in the registry per the #168 analysis). Once acquired:
+diff per language column vs the registry maps; encode genuine gaps;
+note reissues as notes, never silently overwrite.
