Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR shares Lamport transaction state across stores for the same document. It is otherwise mergeable, but the lint configuration currently permits unrelated Map, Set, and WeakSet registries to bypass the intended guard, so the exception should be narrowed or explicitly accepted before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

official ESLint no-restricted-syntax selector esquery :not VariableDeclarator documentation
💡 Result:
In ESLint's no-restricted-syntax rule, the selector:not(VariableDeclarator) is a valid application of the esquery negation pseudo-class [1][2]. This selector matches any Abstract Syntax Tree (AST) node that is not a VariableDeclarator [1][3]. The:not pseudo-class functions similarly to CSS negation selectors, allowing you to filter out specific node types from a match [1][2]. For example, the official ESLint documentation uses a related pattern, IfStatement >:not(BlockStatement).consequent, to identify if statements whose consequent is not a block statement [1][4]. When using this in your ESLint configuration, you can apply it as follows: { "rules": { "no-restricted-syntax": [ "error", ":not(VariableDeclarator)" ] } } Note that applying:not(VariableDeclarator) broadly will attempt to restrict almost every node in your AST that is not a variable declarator, which will likely result in widespread errors across your codebase [1][5]. It is generally used in combination with other selectors to create precise exclusion logic [1].

Restrict the documentTransactionTails exception to new WeakMap().
The esquery :not filter excludes the entire VariableDeclarator, so Map, Set, and WeakSet declarations with this name bypass KA-13. Match the exception only for a direct new WeakMap() initializer.

Closes #125.
Shares the Lamport transaction tail across all stores wrapping the same Y.Doc, adds the two-instance concurrency regression, and amends ADR-021 plus the KA-13 guard for the narrowly named weak registry.
