Summary

ALA-LC batch 3 (Cyrillic) — encodes the two systems of the batch whose source documents are present in the collection, transcribing the entire tables and their notes. Pure addition: two new .isc files, no existing file touched.

Systems encoded

Map	Source document	Pages	Notes
alalc-chu-Cyrl-Latn-2022	alalc-church-slavic.pdf (2022 version; earlier versions 2011, 1997)	p. 1-2 table, p. 2-3 notes	Full Church Slavonic alphabet: yuses, ksi, psi, fita, izhitsa, both uk forms, ot ligature; numeric-value column carried into metadata notes; document notes 1-4 (diacritics, abbreviations, numerals, dates) transcribed
alalc-rue-Cyrl-Latn-2013	alalc-rusyn.pdf (2013 version, no earlier versions)	p. 1-2 table, p. 2 prose + notes	Ukrainian-style gh/g distinction, iotated vowels with the I-macron + tie convention, yaty → i-circumflex, yery → y-circumflex; ligature rows zh/kh/ts per notes 1, 3, 4

Both romanization tables embed low-resolution raster images for their diacritic-bearing cells (iotated vowels, ot, ts, ks, ps, yery-macron, fita, izhitsa). Every such cell was verified at magnification from the extracted image rasters; the encoding follows what the images show: I-macron + tie (U+0361) + vowel for the iotated letters (Ī͡e, Ī͡u, Ī͡a, Ī͡ę, Ī͡ǫ), Ō͡T/ō͡t for the ot letter Ѿ/ѿ, and tied digraphs for ж/х/ц in Rusyn (z͡h, k͡h, t͡s) and Ц/Ѯ/Ѱ in Church Slavic (t͡s, k͡s, p͡s).

Ambiguous rows and source errata (flagged, not silently "fixed")

Church Slavic:

• The lower-case row for и prints the romanization as uppercase I in the source table. Encoded as i for case parity; flagged in the map notes.
• ћ is romanized ǵ (soft g in Serbian-printed Church Slavonic) — distinct from the Serbian table's đ; per the source row.
• Ѷ (izhitsa): the table's alternative rendering v̇ "if used without diacritical marks" cannot be resolved without reading context; only the vowel rendering ẏ is encoded.

Rusyn:

• The upper-case romanization cell for Я shows only ī — a defective cell in the source. Encoded as Ī͡A per the lower-case cell (ī͡a) and the pattern of the other iotated rows.
• The vernacular cells for the yo and o-circumflex rows print Latin codepoints (Ë U+00CB, Ô U+00D4). The map keys the Cyrillic inputs Ё/ё (U+0401/U+0451) and О + combining circumflex (U+0302).
• The lower-case row for ф prints romanization F; encoded as f.
• The hard-sign row prints ʹʹ (two primes); encoded as ʺ (U+02BA), matching the Church Slavic table.
• И has two rows (note 2): i for Vojvodinian publications, y for all other materials. The map encodes the general rule y; the regional variant is documented in notes (it depends on publication provenance, not text).

Tests carried

The source documents contain no example words beyond the tables, so every table row (upper and lower case) is carried as an embedded test — same convention as the existing bsi-chu map: 98 tests (chu) + 78 tests (rue).

Source not in collection (from the batch work order — NOT encoded)

• ALA-LC Bashkir — no alalc-bashkir.pdf in the collection
• ALA-LC Chuvash — no alalc-chuvash.pdf in the collection
• ALA-LC Udmurt — no alalc-udmurt.pdf in the collection
• ALA-LC Komi — no alalc-komi.pdf in the collection
• ALA-LC Yakut/Sakha — no alalc-yakut.pdf / alalc-sakha.pdf in the collection

Verification

All against a fresh interscript-ts main checkout (scripts/-side parser and runtime):

• Embedded tests through the TS runtime (parse + compile + transliterate): 176 passed, 0 failed

  npx -y tsx <driver>   # parseIsc + iscBundledStrategy + transliterate over every tests{} entry
  

• Full-corpus parse gate with the TS parser over the branch corpus: Parsed 406/406 .isc files (the maps/ CI-gate equivalent; the runtime's own scripts/parse-all-isc.ts expects a maps sibling checkout)
• Mixed-sequence sanity through the runtime: Ѿцъ → Ō͡Tt͡sʺ, Глаголица → Glagolit͡sa, ѥюꙗѨѬ → ī͡eī͡uī͡aĪ͡ĘĪ͡Ǫ, rue Русин → Rusyn, ґг → gh
• git status shows only the two new files (pure addition)

No merge — awaiting review.
