Topics — What a work is about. Nucleation holds whatever reading the owner files here, whether or not an Anthology of the SOTA topic could also hold it; instruction for ML practice belongs to the anthology (ADR-048). The words are seeded from the clusters the reading-time triage of 2026-09-25 found, and grow by decision.
Information retrieval — finding what is relevant to a need — document and query representation, relevance and aboutness, ranking and feedback, and the geometric, probabilistic and logical models of retrieval.

| CASE-094 | The LEGO bin: a brick owned in one copy and buried among hundreds of similar ones may as well not be owned, a black brick among white ones needs no bin of its own, and every brick can be found by going through the whole collection | The owner’s own parable, told on 2026-07-02 and kept verbatim in Mathematics of Meaning, where the owner paired it with the EMT case this record holds as CASE-085. It is the second time that case’s pattern has turned up, so it gets a code. It adds three things the EMT case lacks: similarity to binmates as the cause of the failure, copy count and frequency of use as what decides whether a bin is worth making, and exhaustive search as the reason presence is never in doubt. Stipulated: the collection is real, and its facts are taken on the owner’s account. | Active |
| CASE-095 | Two builders sorting one collection: the brick that one bins as red and two-wide and the other as a curved connector has a bin that respects both, and what the builders cannot share is an arrangement, not a description | The example the owner’s LEGO monograph (Mathematics of Meaning, “The Lego Parable”) uses for contextuality, rebuilt. As descriptions the two sortings always share a joint refinement, the product bin, as MOM-CLM-137 shows, so they illustrate the non-contextual case of CLAIM-037 and CLAIM-131. As arrangements, with a fixed number of bins, they compete, and which wins depends on the queries made and on what stands out within a bin. Fictional: the builders and the collection are invented. | Active |
| CASE-132 | One complaint, two taxonomies: a report of an unsafe practice is correctly classified both by equipment and by workers’ obligations, the intake procedure needs one primary class, and the class chosen decides whether the report reaches a body that can change working conditions | A18’s CASE O in the exchange of 2026-10-22, from the owner’s request for cases on whether “some apparent conceptual disputes are really disputes about the allocation of limited representational resources” (U18). Two true classifications compete not for truth but for uptake. Not shown: when routing becomes an allocation of authority, which the case asks. | Active |
