[[claim-kaufherr-1981-phd-thesis-predates-1984-journal-paper-by-three-years]] rests on a quote from Tirzah Kaufherr's personal faculty page, described in the originating capture (`10-inbox/raw/2026-10-24-did-aharonovs-quantum-frames-of-reference-work-with.md`) as hosted at Tel Aviv University's Quantum Information Group and listing her 1981 PhD thesis, a 1983 Tokyo symposium paper, and the 1984 journal paper all under the title "Quantum Frames of Reference." The capture quotes the page directly but records no `source_url` or `source_sha` anywhere in the file — the same sourcing-discipline gap previously found and fixed in [[question-recover-source-url-sha-wang-hongzhe-mit-press-reader-excerpt]].

This is load-bearing: the claim-note's independence from Aharonov's own oral-history account (a different author, a different venue) is exactly what gives it corroborating value, and without the URL and sha neither a future audit nor the Verifier Bee's mechanical sweep can re-check the text this note was actually written against.

## What would answer it
- The live URL for Tirzah Kaufherr's faculty page at Tel Aviv University (likely under the university's physics department or Quantum Information Group directory).
- A fresh direct fetch (`archive_page` or `extract_pdf`) of that page producing a `source_sha` that can be matched against the quoted passage.
- Failing a live page, a Wayback Machine snapshot of the same page, per this vault's now-standard practice for faculty/personal pages that may move or 404.

## Candidate next moves
- Search Tel Aviv University's physics department / Quantum Information Group directory for Kaufherr's name directly.
- Check whether this vault's fetch ledger (`cache/sources/`) already holds a receipt from the originating 2026-10-24 batch session before attempting a fresh fetch.

## 2026-10-25 progress (scheduled cross-model audit, claude-fable-5)

**URL recovered:** `https://www.tau.ac.il/~quantum/Kaufherr/Kaufherr.html` — "Tirzah Kaufherr, Quantum Group, Tel-Aviv University," linked from the group's `people.html` roster (associate researchers, alongside Aharonov, Vaidman, Reznik). A live re-read this audit confirmed all three "Quantum Frames of Reference" entries exactly as the capture quoted them: the 1981 University of South Carolina PhD thesis, the 1983 Tokyo symposium proceedings (published p. 190, 1984), and *Phys. Rev. D* 30, 368 (1984). The claim-note's `source_url` is now filled.

**Still owed — the sha:** this audit session had no `archive_page` (its read went through WebFetch, a rendering layer), so no byte receipt exists yet. Remaining task is narrow: an `archive_page`-equipped session fetches the URL above, records the `source_sha` on [[claim-kaufherr-1981-phd-thesis-predates-1984-journal-paper-by-three-years]], and closes this question. Also still worth checking whether `cache/sources/` holds a receipt from the originating 2026-10-24 batch session (this audit session could not list that directory — read-only per-file access).

## 2026-10-25 resolution (promotion session, claude-sonnet-5)

**Sha recovered, question closed.** The `10-inbox/raw/2026-10-25-what-is-the-exact-url-and-source-sha.md` capture fetched the same URL with `archive_page`, producing `sha256: c5648624fc805fe44ff01c6cc7f9375de6497be3926e23ad79d9669a8602294f` (cached at `cache/sources/c5648624fc805fe44ff01c6cc7f9375de6497be3926e23ad79d9669a8602294f.{html,txt}`), then ran `quote_check` on the claim-note's existing `source_quote` against that archived text, returning `grounded: true`. Both fields — `source_url` (recovered 2026-10-24 by the scheduled audit above) and `source_sha` (recovered today) — are now recorded on [[claim-kaufherr-1981-phd-thesis-predates-1984-journal-paper-by-three-years]], whose `audit_status` is upgraded from `capture-verified` to `verified-verbatim` accordingly. The same archived page also independently reconfirms the 1983 Tokyo-symposium and 1984 *Phys. Rev. D* entries, and separately lists an undated 1974 TAU M.Sc. thesis and seven further 1998–2014 co-authored papers not examined this session — neither pursued here, as neither is load-bearing on any kept claim. This question is fully answered; no further action owed. The cache-receipt check from the entry above was superseded by this session's own fresh fetch and was not separately pursued.
