A side research pass turned up a far better source text for your Könchok Chidü (Könchok Chidü / dkon mchog spyi 'dus — "The Embodiment of the Three Jewels," Jatsön Nyingpo's terma cycle; terma = a teaching hidden by Guru Rinpoche for later revelation) study, made by a team worth knowing about and possibly supporting.
Rinchen Terdzö (rin chen gter mdzod, "Precious Treasury of Termas") is Jamgön Kongtrül Lodrö Thaye's 19th-century compilation of the core practice texts of the terma tradition — empowerments, practice manuals, and instructions — gathered from termas revealed across every lineage of Tibetan Buddhism that has this kind of hidden-teaching tradition. It's one of the "Five Great Treasuries" Kongtrül is famous for compiling, and it's treated as a foundational reference collection for that entire practice tradition, not just one teacher's writings.
Scope, in numbers: the modern Shechen edition (see section 3 for who made it) runs to 71 volumes plus 1 volume of illustrations (72 physical volumes) — a critical edition that collated older prints and rare manuscripts. It was finished and formally celebrated in 2018.
Your Könchok Chidü cycle is one cluster of texts inside this larger collection — it sits in volume 8 ("NYA") and part of volume 13 ("PA") of the digital edition.
A 1977 reprint of a single handwritten manuscript, run through Google-Vision OCR (optical character recognition — software guessing letters from a scanned image) in 2020.
Every character was typed by a person and proofread by a person — not scanned and guessed. BDRC's own record tags it "ContentMethod: Computer Input," their label for hand-entry as opposed to OCR.
curl -L "https://purl.bdrc.io/resource/UT1KG14_008_0019.txt" -o las-byang.txt — the full command list is in the research doc (see footer). For browsing rather than downloading, rtz.tsadra.org (the same edition, laid out as a readable wiki with a scanned-PDF view) is the friendlier way in — though it only works in a normal browser, not from a script.
The complete findings — every fetch command, the full BDRC ID map, and the OCR-tool verdict for your own scans — is saved as a standalone doc: TIBETAN-RESEARCH-FINDINGS-2026-07-03.md, in your Google Drive under KONCHOK-CHIDU-RESEARCH/ (synced) and copied to the mac-mini home folder.
