What's in it
modules/02-converged-vs-multi-model— 3 proofs, 18 assertions:01-survey-challenge.sql— the Lu & Holubová (ACM CSUR 2019) Fig. 1 multi-model challenge answered in one standard SQL statement (SQL/PGQ GRAPH_TABLE + SQL/JSON JSON_TABLE), asserting the survey's published result set exactly, plus one-plan EXPLAIN evidence.02-one-enforcement-domain.js— the same CHECK constraint rejecting an illegal write through the MongoDB-compatible API and through SQL ($sql), one enforcement domain.03-read-after-write-search.sql— committed row findable by CONTAINS in the next statement (SYNC ON COMMIT), read-after-write across a commit boundary.Validation: module runs green in the lab validator (fresh-container build); the path-scoped CI workflow covers it on this PR.
Note: the article-2 blog link in the module map lands at publish (article not yet announced).
