# Marta, Tartaria and 1923: source notes
Reviewed and published October 18, 2026.

## Evidence classification
Unverified historical narrative; related telling explicitly described as dramatized or constructed storytelling. Genuine Tartary map terminology is not evidence for the alleged witness or citywide energy system.

## Capture and provenance
The supplied Facebook share resolved to Reel 2005443576824449, Thepoddaddy. Full video, thumbnail, public caption and metadata preserved privately. Complete audio transcribed locally with faster-whisper; automated place-name spellings were cross-checked with related written descriptions. Full video is not republished: an opening 84-second excerpt identifies the claims under review and the article links to the complete original.
Contact sheets were generated; automated visual analysis failed with a provider parameter error. No claim is made that images are authentic, AI-generated, or that all visible paperwork was inspected. Captured audio and caption supply the claim identification.

Tartaria Vault YouTube _ri128W4t14: direct yt-dlp metadata verifies title, channel, 2026-09-04 upload date and the explicit description disclaimer. The same distinctive story appears in Facebook narration; an exact visual/audio source match and original authorship were not established. The disclaimer is attributed only to the related YouTube publication, also repeated on ALIVE528. Hyacinth Research embeds the same YouTube ID. These are narrative-provenance sources, not historical corroboration.

## Primary-record limits
Exact English clinic/story searches and German Hirtenweg/Klinik/Zurich/1919 variants did not establish a contemporary clinic file or authenticated Marta identity. Search engines returned unrelated and repeated modern material. No complete Swiss archive audit or private medical-record access was performed; absence from search results does not prove a clinic/person never existed. We did not establish a repository/call number/scan/chain of custody for the claimed four-page record, Dr. K report, death certificate or city-investigation findings.

## Historical/scientific anchors
Library of Congress blog article read directly; its editorial entry was separated from reader comments. Catalogue entry for 1757 map supports existence of historical map, not the technical story. A separate LOC JSON/image attempt was blocked; no map image is republished.
University of Zurich distinguishes bynames from hereditary surnames and supplies medieval documentary examples. Do not imply universal naming rules.
Guinness record is a verified-age comparator, not proof of a hard lifespan ceiling.
University of Washington confirms street raising during Seattle rebuilding; not a universal explanation for all underground spaces.
Reading confirms atmospheric-electricity measurements, not ancient power generation. No energy-output estimates or fabricated experiments supplied.

## Key claim locations (approximate automated transcript timings)
00:00–01:35: Marta, alleged clinic, 147-year age, 1923 death and four-page file.
01:46–01:57: supposed recent-invention surname claim.
02:34–06:43: warm roads/walls, light towers and the flow.
06:49–07:14: Tatar/Turkic vocabulary and Tartary geography.
09:38–12:04: underground city claims, copper tower and atmospheric electricity speculation.
12:04–13:18: old-map discussion, including ordinary cartographic explanations.
14:20–15:32: allegedly withheld remainder and Dr. K.
16:43–17:23: alleged April 14, 1923 death and final notation.
The video itself acknowledges several speculative steps. The article preserves those caveats.
