 "abstract": "A prospect scale broadband magnetotelluric survey over the Hillside iron oxide copper gold deposit on eastern Yorke Peninsula, South Australia, recorded by Adelaide University between 21 March and 7 July 2012 in two field phases, 45 stations in March and 28 in July. Seventy-two of the 73 soundings are served here and one is withheld. They cover about 2 km east to west by 3 km north to south, and include a 15 station profile, HSSL01 to HSSL15, along a seismic line. Each site logged Ex, Ey, Hx and Hy at 1000 Hz on an Earth Data PR6-24 with LEMI-120 induction coils on dipoles of 34 to 51 m; Hz was recorded everywhere but not processed, so no file carries a tipper. Transfer functions were computed with BIRRP 5.1 against a remote site and are served as the delivered splice of the remote referenced short period and decimated long period results, 46 periods from 0.0064 to 218.4 s.",

  "changes_summary": "Nothing inside any file is changed. All 72 served EDIs are byte identical to the harvested files, proved by sha256 against the read-only harvest and recorded per file in provenance/served-files.json. Not even a filename is AusMT's: each served file keeps the name the harvest gives it, which is already the file's own DATAID. One of the 73 soundings the harvest holds for this survey, HS055b, is WITHHELD rather than altered: the engine's sign gate refuses it, and under owner ruling 2026-09-19 (the YMB057 precedent), applied here by precedent, such a station leaves the served set with a note. Its delivered file is kept byte identical at provenance/as-delivered/HS055b.edi and the evidence and the ruling are recorded in provenance/served-files.json. An omission is not an edit: no number, no header and no byte of any file is changed by it.",
