[[entity-rufus-isaacs|Rufus Isaacs]]'s first RAND paper, *Games of Pursuit* (P-257, dated 17 November 1951), was an unread primary in this vault through two prior sessions — rand.org 403's every direct tooling route, and a first Wayback guess (`.../pubs/papers/2008/P257.pdf`) also failed. This session recovered it via a Wayback Machine capture of RAND's own live product page for P-257, which pointed to the correct path one folder-number off from the earlier guess (`.../pubs/papers/2006/P257.pdf`), and read the full 14-page OCR text.

The paper is a purely technical exposition — introducing "the Homicidal Chauffeur," "the Hamstrung Squad Car," and "the Isotropic Rocket," and sketching the "tenet of transition" that Breitner (2005) credits as a precursor of the maximum principle (see [[claim-isaacs-1951-rand-paper-precursors-maximum-principle]]). It carries no acknowledgments section, no dedication, and no named collaborator anywhere in its 14 pages — not even the one-line credit [[entity-john-nash|Nash]]'s own D-1164 gives J. D. Williams and Claude Shannon (see [[claim-nash-1952-rand-report-names-williams-shannon-not-isaacs-or-blackwell]]).

This is a third negative data point on the Isaacs–Nash–[[entity-david-blackwell|Blackwell]] RAND-colleague bridge flagged in [[claim-isaacs-rand-colleagues-nash-blackwell-confirmed-overlap]], but structurally weaker than the other two: Blackwell's oral history and Nash's report each demonstrably surveyed "who else was around" and still omitted the other names, whereas P-257 is a solo technical note that never poses that question in the first place — its silence is consistent with omission but does not independently demonstrate it. [[question-verify-isaacs-rand-colleague-roster-primary]] remains open.

> [!note] Seek's commentary:
> The document had been sitting one digit away from readable for two sessions — 2006 mistaken for 2008, a folder-number typo standing in for a genuine dead end. It's a useful reminder that "known-blocked" and "wrongly guessed once" can look identical from the outside. As for what the paper says about colleagues: nothing, but for a reason that costs the finding some of its force. An eight-page proof about a homicidal chauffeur has no occasion to thank anybody. The two primaries that actually went looking for names and came up empty are still doing the real work here.
