    "result": "## Preconditions\n\n1. Every emitted program is a single MLIR module whose top level consists only of `dataflow.thread` definitions and `func.func` host functions, with no other module-scope operations, attributes, or nesting.\n2. Every `dataflow.thread` definition is declared `private` and is named `@thread_N` where `N` is the zero-based index of the definition in module order.\n3. Every `dataflow.thread` definition carries the domain attribute `domain(#dataflow.thread_domain<dense>)` and no other domain kind.\n4. The entry block of every `dataflow.thread` begins with the argument `%buf: memref<8xi32>`, which is always present and is the first declared argument.\n5. Any additional entry-block payload arguments follow `%buf` in a comma-separated list, are named `%arg0`, `%arg1`, \u2026 in consecutive zero-based order, and each is annotated with exactly one of the element types `i32`, `f32`, or `index`.\n6. Every `dataflow.thread` definition declares a control argument in a separate clause written `ctrl (%thread_ctrl: none)`, of type `none`, placed after the payload argument list.\n7. A definition with a nonzero launch-domain rank declares a coordinate clause ` iv (...)` after the `ctrl` clause containing exactly one `index`-typed argument per domain dimension, named `%coord_0`, `%coord_1`, \u2026 in consecutive zero-based order and separated by `, `.\n8. A definition whose launch-domain rank is zero emits no `iv` clause at all, and its paired launch emits no `grid` clause; the presence of the coordinate clause and the presence of the grid clause are strictly linked.\n9. The body of every `dataflow.thread` begins with the SSA definition `%value = arith.constant 7 : i32`, so any operation consuming `%value` is dominated by its definition.\n10. If an `scf.forall` appears in a thread body, it is written in effect form: it has no `shared_outs` clause, produces no results, carries no mapping attribute, and has an implicit empty `in_parallel` terminator (no explicit terminator region is written).\n11. Any emitted `scf.forall` has exactly one induction variable `%lane` and a single-dimension upper bound given as a compile-time integer literal, with an implicit zero lower bound and unit step.\n12. The sole operation inside any `scf.forall` body is `memref.store %value, %buf[%lane] : memref<8xi32>`, storing the thread-body constant into the entry-block memref at the induction variable, and the store index range is bounded by the memref's static extent of 8.\n13. Every `dataflow.thread` body is terminated by a `dataflow.thread.yield`, either with no operands or with the single operand `%thread_ctrl : none` taken from the declared control argument.\n14. Each `dataflow.thread` definition is immediately followed at module scope by exactly one host function `func.func @host_N()` whose numeric suffix matches that definition, taking no arguments and returning no results.\n15. Each host function allocates its buffer with `%buf = memref.alloc() : memref<8xi32>`, whose type matches the first entry-block argument type of the callee.\n16. Each host function defines one SSA constant `%h0`, `%h1`, \u2026 per extra payload argument of its callee, in consecutive zero-based order, and the constant's type and literal form match the declared type of the payload argument at the same position (`arith.constant 3 : i32`, `arith.constant 1.000000e+00 : f32`, or `arith.constant 2 : index`).\n17. Each host function defines one `index` constant `%g0`, `%g1`, \u2026 per launch-domain dimension, in consecutive zero-based order, before the launch.\n18. Every host function contains exactly one `dataflow.thread.launch @thread_N(...)` whose callee symbol matches the preceding definition and whose operand list is `%buf` followed by `%h0 \u2026 %hK` in the same order and arity as the callee's declared arguments.\n19. The launch's explicit operand type list is `(memref<8xi32>` followed by the payload types in declaration order `) -> !dataflow.thread_token`, so the signature written at the launch agrees element-for-element with the callee's entry block, and the launch yields exactly one token result bound to `%token`.\n20. When the callee declares coordinates, the launch carries a `grid(...)` clause listing exactly the `%g0 \u2026 %gR-1` constants, one per coordinate argument, in order and separated by `, `, so grid arity equals coordinate arity.\n21. All constant definitions in a host function precede the launch that uses them, and the launch precedes the terminating `return`.\n22. Every host function ends with `return` and a closing brace, and contains no operation consuming `%token`.\n23. No emitted program uses the thread's coordinate arguments or payload arguments inside the thread body; the only value flowing into the body's operations is `%value` and `%buf`.\n\n## Sampling conventions\n\n1. The module contains between 1 and 3 `dataflow.thread` definitions inclusive, each paired with its host function, and definitions/host pairs are emitted interleaved (definition then its host function) rather than grouped.\n2. The number of extra payload arguments per thread is chosen independently per thread from 0 to 2 inclusive, so total entry-block arity ranges from 1 to 3.\n3. The launch-domain rank per thread is chosen independently from 0 to 2 inclusive, so a definition has zero, one, or two coordinate arguments; ranks of 3 or more are never emitted.\n4. Each extra payload type is drawn independently from exactly the three-element set `i32`, `f32`, `index`; no vector, memref, tensor, or other types appear in payload positions.\n5. The buffer type is fixed to `memref<8xi32>` in every definition and every host allocation; no other shape or element type is ever emitted.\n6. The thread-body constant is fixed to `arith.constant 7 : i32`, and the host-side constant literals are fixed per type (3 for `i32`, 1.000000e+00 for `f32`, 2 for `index`).\n7. The grid constants are always `arith.constant 4 : index`, identical for every dimension, so no non-uniform or non-constant grid sizes are exercised.\n8. The `scf.forall` upper bound is drawn from exactly `2`, `4`, or `8`; other extents, including extents exceeding the memref's static size, are never emitted.\n9. The `scf.forall` is optional: a thread body either contains exactly one such loop or contains none, and never contains two or more, nor any nested or sibling loops.\n10. The yield form is chosen between the operandless `dataflow.thread.yield` and the control-passing `dataflow.thread.yield %thread_ctrl : none`; no other operand sets are emitted.\n11. Names follow fixed schemes with zero-based consecutive numbering and no gaps: `@thread_N`/`@host_N` for symbols, `%argI` for payload arguments, `%coord_K` for coordinates, `%hB` for host payload constants, `%gG` for grid constants, plus the fixed names `%buf`, `%thread_ctrl`, `%value`, `%lane`, and `%token`.\n12. Indentation is fixed: module-scope operations at column zero, thread-body and host-body operations indented two spaces, and the `scf.forall` body indented four spaces.\n13. Separators are fixed: `, ` between coordinate declarations, grid operands, payload declarations, launch operands, and launch operand types, with no trailing separator before a closing parenthesis.\n14. The `dataflow.thread.launch` result is always bound to `%token` even though it is never consumed, rather than using a result-discarding form.\n15. Host functions are always named after and matched one-to-one with their callee, never sharing a host function across threads and never launching a thread more than once.\n16. The store inside the loop always writes the same `%value` to the same `%buf`, so no aliasing, multiple-buffer, or load-based access patterns are exercised.\n17. The skeleton is kept flat and finite: no control flow other than the optional single `scf.forall`, no calls other than the launch, no region-bearing ops besides `dataflow.thread`, `func.func`, and `scf.forall`.",
