The hook question, as posed, conflates two distinct Hardy-named threads that
need to be pulled apart before either can be answered. (1) The 1988 paper
that coined "the confused deputy problem" — already Tier-1 confirmed in this
vault as [[claim-hardy-1988-named-confused-deputy-compiler-billing|Norman
Hardy's own work]], hosted under his own name at cap-lore.com. (2) The
Tymshare/KeyKOS build-credit story — already partly captured
([[claim-ann-hardy-tymshare-os-miscredited-to-husband]],
[[claim-norman-hardy-tymnet-account-confirms-ann-hardy-wrote-os]]) for the
1960s SDS-940 operating system layer, where Ann Hardy's authorship is
Tier-1 confirmed and Norman Hardy's own writing independently corroborates it.

This capture finds no evidence that thread (1) is itself a misattribution —
Norman Hardy's authorship of the confused-deputy paper is uncontested
everywhere this session looked. What the record does show, newly, is that
thread (2) extends one layer further than the vault had captured: into
KeyKOS itself, where Ann Hardy has a documented, Tier-1 technical/authorial
credit that at least one major tertiary source (Wikipedia's KeyKOS article)
currently omits. The drift the topic asks about is real — it just lives one
level away from the confused-deputy paper's own byline, not on it.

## Claim: Norman Hardy's authorship of the 1988 "confused deputy" paper is uncontested in every source found — it is not itself a case of misattribution

A broad search of the capability-security literature, course readings, and
vendor/glossary pieces that cite or discuss "The Confused Deputy (or why
capabilities might have been invented)" turned up no source crediting the
term or the paper to anyone other than Norman Hardy. The paper is hosted
under his own byline at his own site and reproduced, with his name attached,
across numerous university course pages (MIT, Stanford, UT Austin,
University of Washington). This is a negative/absence finding — the search
cannot prove no counter-attribution exists anywhere, only that none surfaced
— but combined with the vault's existing Tier-1 confirmation of his own
hosted text, it supports treating thread (1) as settled and uncontested,
distinct from thread (2) below.

## Claim: Ann Hardy founded Key Logic and is a named co-author of KeyKOS's own architecture paper — a documented technical/authorial credit at the KeyKOS layer, distinct from the Tymshare-OS case

After McDonnell Douglas acquired Tymshare (1984–85), Ann Hardy founded Key
Logic, Inc., with funding from Gene Amdahl, to commercialize Tymshare's
in-house capability-based operating system GNOSIS under the new name KeyKOS.
Her own 2016 oral history describes GNOSIS/KeyKOS as something Tymshare
built entirely in-house, with no borrowed code: "Gnosis was ours. Tymshare's.
We ran it on our 370s for people who wanted straight CMS. And so we could
offer them very high levels of security," contrasting it with the licensed,
externally-derived SDS-940 operating system: "it was more ours than the 940
operating system was ours or, you know, it was just ours. We wrote it from
the ground up."

Separately and more directly: the primary technical paper describing the
system — "The KeyKOS® Nanokernel Architecture" (Proceedings of the USENIX
Workshop on Micro-Kernels and Other Kernel Architectures, Seattle, WA, April
1992, pp. 95–112) — lists seven authors in its byline, including both
Hardys: "Alan C. Bomberger / Norman Hardy / A. Peri Frantz / Charles R.
Landau / William S. Frantz / Jonathan S. Shapiro / Ann C. Hardy." Ann Hardy
is a named co-author of KeyKOS's own foundational architecture document —
Tier-1, primary, uncontested.

## Claim: Wikipedia's current KeyKOS article omits Ann Hardy from its "Developer" field — the drift documented in the vault's Tymshare-OS claim extends, uncorrected, to this tertiary source's account of KeyKOS

As archived this session, the English Wikipedia "KeyKOS" infobox lists:
"Developer	Tymshare (Norm Hardy, Bill Frantz, Charlie Landau) / McDonnell
Douglas / Key Logic." Ann Hardy — the founder of Key Logic (the company
listed) and a named co-author of the system's own architecture paper (claim
above) — does not appear in the developer credit at all, despite the
article naming three of her co-authors individually. Separately, Wikipedia's
own "Ann Hardy" biography article, archived the same session, describes her
founding "KeyLogic, which sold the timesharing hardware and software
developed at Tymshare, under a licensing arrangement" — a description that
itself never names GNOSIS, KeyKOS, capability-based security, or her
co-authorship of the architecture paper. Two Wikipedia articles describe the
same company and the same system; neither credits her technical role in it.
This is a directly-observed fact about what a specific, widely-read tertiary
source currently says (the page is read here as the primary artifact of its
own content, not as evidence of the underlying 1980s history) — it does not
establish why the omission exists, only that the correction visible in the
1992 primary paper and in CHM's oral-history-based retellings has not
propagated to this particular article as of this archive date.

## Claim: Ann Hardy's own oral history attributes GNOSIS's original (c. 1970) design team to Dale Jordan and Norman Hardy, not herself — a complication, in her own words, of a clean "she built it, he got credit" narrative at the KeyKOS/GNOSIS layer specifically

Asked directly about GNOSIS's origin, Ann Hardy's own account names a
different team than the one her later co-authorship (claim 2 above) might
suggest: "And so by 1970 there was a small team of people. Dale Jordan. I
think it was Dale. Maybe Bill Weiher and Norm. I know it was Dale and Norm.
Somebody else. Were put, designed, this operating system called Gnosis.
Which is a capability-based system, and if you want to know details, you
really need to talk to, interview, Norm." This is Ann Hardy's own testimony
deferring the original design credit to Norman Hardy and Dale Jordan, and
explicitly declining to claim it for herself — a materially different
posture than her account of the SDS-940 rewrite, where she describes sole,
unambiguous authorship. The two layers of the Hardy/Tymshare story are not
symmetric: at the OS layer the vault's existing claim is that she built it
alone and was miscredited; at the GNOSIS/KeyKOS layer, by her own words, the
original design was a small team she names as led by others, with her
documented credit (claim 2) arriving later, as a listed co-author of the
system's architecture and as the executive who founded the company that
commercialized it.

## Further leads

- The CHM blog "If Discrimination, Then Branch: Ann Hardy's Contributions to Computing" (David C. Brock, March 25, 2019, Core magazine / computerhistory.org) states her two oral-history sessions were interviewed "on February 20, 2018" and "July 22, 2018" — directly contradicting the oral-history PDF's own header, which reads "Recorded July 22, 2016." Unresolved date discrepancy between CHM's own blog and CHM's own transcript header; not load-bearing to any claim above, so not routed to 50-questions/, but worth flagging for a session that needs the exact interview date.
- Charlotte Helander — a Tymshare employee Ann Hardy credits (same oral history, Session 2) with introducing a formal pre-coding design-and-documentation discipline that sharply cut bug rates — an uncaptured process-history thread, not pursued here.
- Dale Jordan — named by Ann Hardy as a (the?) lead designer of GNOSIS alongside Norman Hardy — appears in neither Wikipedia KeyKOS/GNOSIS article; worth checking CHM's catalog or Norman Hardy's own cap-lore.com writing for an independent account of his role.
- cap-lore.com/CapTheory/KK/ (Norman Hardy's own KeyKOS site, referenced by Wikipedia as "Roots of KeyKOS") was not independently fetched this session — a likely richer primary source on the GNOSIS→KeyKOS lineage and who did what, not yet read.
- Charles Babbage Institute oral history of Ann Hardy (OH 458, interviewed by Jeffrey R. Yost, 3 April 2012, hosted at conservancy.umn.edu) was not read this session — a second independent primary transcript that may speak to the KeyKOS/Key Logic years specifically (the existing vault notes read it for the Tymshare/Tymnet years only).

## Entity candidates

- Norman Hardy — person — the figure the whole attribution-drift question is measured against at both layers (OS authorship and, per claim 4, original GNOSIS design credit); already referenced throughout the vault's existing claim-notes but has no entity page yet.
- Dale Jordan — person — named by Ann Hardy herself as a lead designer of GNOSIS alongside Norman Hardy; absent from both Wikipedia's KeyKOS and GNOSIS articles entirely — a second, un-flagged under-credited figure in the same story.
- Ann Hardy — person — the capture's subject; referenced heavily in the existing vault but has no entity page yet.
- Key Logic, Inc. — concept/org — the company Ann Hardy founded (funded by Gene Amdahl) to commercialize GNOSIS as KeyKOS; distinct from Tymshare and from Key Logic's eventual closure in the early 1990s.
- KeyKOS / GNOSIS — concept — the capability-based operating system itself, predecessor to EROS/CapROS/Coyotos; the technical object both Hardys' credit disputes are about.
- Gene Amdahl — person — funded Key Logic's founding, per CHM's catalog description; a one-line mention not otherwise explored.
- Jonathan S. Shapiro — person — co-author of the 1992 KeyKOS nanokernel paper alongside both Hardys; later the architect of KeyKOS's own successor system EROS — a continuity figure between this story and later capability-OS work.
