Agent grep index. Behavior belongs in executable tests.

Never

• Generic State / runState / Ref-via-effects

• Result / Ok / Err as default fallible control flow

• npm/React/TypeScript FFI as an app boundary

• Node/Deno/Bun server targets

• Generated Rust, OCaml, LLVM, Cranelift, or bytecode backends

• Display strings as module/type identity

• CRDT application rows

• Git-style data merging, bitemporality, or wire-version negotiation

• Public generated-sync JavaScript API

• Database-member named queries or query AppDb blocks

• Middleware/webhooks/adapters inside sync ordering

• Product visibility as sync audience

• Unordered workflow-only membership rebuild

• Fake services that only seal free builtin hosts

• pure meaning “no host I/O”

• Task-returning stdlib I/O

• Task-only await or type-specific scheduler wait paths

• Intrinsics, private intrinsic modules, or public primitive_* twins

• Schema-local renamed_from history or migration blocks inside live database declarations

Not Primary

• User.t outside-type spelling

• Receiver/method dispatch

• Rust impl Type behavior blocks

• with type, generative functors, or first-class-module unpacking

• Ambient behavior-instance search

• Universal borrow checking or routine lifetimes

• Repeated derive boilerplate

Tooling

• Cargo-style package management

• Proc-macro-first metaprogramming

• Manual test-database preparation

• Summary-only plans or write-capable dry runs

• Central runner/provider operation enums or opaque plan closures

• Any, TypeId, trait-object nodes, or registration-order identity

• String/JSON workflow protocols

• Premature workflow-executor crate splitting

• One-command-first workflow graph design

Syntax

• var, ref/!, or <- assignment

• * keyword-parameter separators

• Callback shorthands

• Grapheme-first or indexable String

• Punctuation open-row algebra

• Unlabeled HOF callback literals

• Call-style product construction

• set(...) or brace-and-pipe sets

• TypeScript as const inference

• Punctuation product projection

• + or & module-signature composition operators

• OCaml last-defined-wins labels/constructors

• Required return/break block values

• ASI or discarding non-Unit with ;

• A second boolean if syntax

• Jest describe/it

CSS

• Tailwind/utility-string-first styling

• Runtime CSS-in-JS

• Per-render style dictionaries

• Property-constructor CSS DSLs

• OCaml CSS quoting or top-level CSS items

• clsx, CSS.join, or + as primary class composition
