 "summary_md": "This record modelled the `/.well-known/ai-catalog.json` well-known file as if it were a distinct, separately maintained artifact alongside the `ard` record. Reading the ARD v0.91 specification text directly [1] shows this is incorrect: ai-catalog.json is the *same lineage* as ARD -- it is explicitly named in the current spec as \"ARD's predecessor\" path, kept only as an optional legacy fallback that a conformant ARD consumer is not required to read. There is no independent governance, schema, or spec document for ai-catalog.json distinct from the ARD project; it is a prior version of the same well-known manifest concept, now superseded by /.well-known/ard.json.\n\nKeeping this as a separate map entry created a false impression of two competing discovery mechanisms. All content that was useful here (its role as the file most publishers currently serve, per our probe evidence) has been moved into the `ard` record's summary and dispute fields, where the version history and the adoption lag it represents can be read together. This record is marked `withdrawn` rather than deleted so the id remains resolvable and the merge history is auditable; readers of agenticweb.wiki should be pointed to `ard` instead.",
