Eight profiles on a common schema, each marking what was checked against a source this session and what is background recollection. Three are marked unverified in full — Machinations, the play substrates, most of RBG — and say so rather than reading as evaluations. Written straight after three review rounds whose entire yield was claims outrunning what had been checked, so the confidence rule is the first thing in the README. The survey changed the plan, which is what a survey is for. Track C was described in Positioning as open ground. It is not: Browne published 57 criteria for game quality, and Ai Ai already computes designer-facing measures — drama, lead changes, branching factor, completion, duration — from played games. The track becomes adopt, credit and find the gap. The gap looks real: those measures presume a leader, and SHARED GROUND has none — Modes.csv gives its tiebreak as "Not applicable". Track B probably adopts rather than builds. OpenSpiel implements CFR, best-response and exploitability over games that are simultaneous-move, imperfect-information and co-operative, which is all four of GROUND's awkward properties. "Does ATTACK ever pay" is a best-response question, and we spent three review rounds refining a two-policy sweep for it. The first Track B task is now one question — is exploitability meaningful for a co-operative game with a shared threshold — not a build. The cost of not surveying earlier is therefore measurable, and is recorded rather than glossed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
3.1 KiB
Simulators — profiles of systems adjacent to clay-borg
Persisted research, not a link dump. Each profile answers the same questions in the same order so the systems can be compared, and each carries what we actually checked.
Written for ../specs/Positioning.md §1 and
§4 — the field we sit in, and the three tracks. Track A (a second game)
and Track B (game theory as the lens on dynamics) both depend on knowing
what already exists.
The confidence rule
Every claim in a profile carries its source, and a claim from background knowledge is marked
unverified.
This directory was written immediately after three adversarial review
rounds whose entire yield was claims that outran what had been checked
(../reviews/). A profile that quietly mixes a fetched fact
with a half-remembered one is the same failure in a new place — and here
it would be worse, because these profiles are meant to inform whether we
build something or adopt it.

What this survey has already changed
Ai Ai and Browne's criteria are the finding. Track C was written in
Positioning.md as though "assimilate knowledge about why games work"
were open ground. It is not: Browne published 57 criteria for game
quality, and Ai Ai already computes designer-facing measures — drama,
lead changes, branching factor, completion, duration — from played games.
That does not close Track C. It moves it from invent to adopt, credit, and find the gap, which is a much better position and a much smaller claim than the one we were about to make.
