//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │

//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

//                    KERNEL 1 :: SemanticFusedScoreTopK
// ============================================================================
// The crown jewel. Scores chunks via warp-parallel bit-overlap AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level popcount scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// The crown jewel. Scores chunks via warp-parallel byte matching AND finds

// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// The crown jewel. Scores chunks via warp-parallel byte matching AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// Kain native LLVM proving ground.
//
// This file is deliberately broad and executable. It is the first file future
// agents should inspect after ARCHITECTURE.md and MEMORY.md when they need to
// remember that Kain is not only fn/if/let: it has compiler-owned intents,
// worlds, actors, native stdlib services, raw memory helpers, shaders, UI,
// graphics, process, net, fs, input, effects, and async values.
//
// Native LLVM truth for this checkout:
// - The executable lane below is compiled with `kain src/main.kn -t llvm`.
// - Live native code in this file now exercises enum `match`, numeric `for`
//   loops over `range`, `vec!`, `format!`, and `println` in addition to the
//   broader runtime and intent surface.
// - The ownership-memory lane demonstrates first-class `observe`, `collapse`,
//   and `decay` over both Kain heap regions and imported/local pointers.
// - Array `for`, receive, emit, user-defined macro expansion, and the more
//   exotic trait-dispatch corners remain deliberate backend proving targets.
// - Shader declarations are validated by the compiler and native graphics
//   runtime, while SPIR-V/PTX/CUDA artifact generation remains the GPU backend
//   lane rather than the primary focus of this example.

//  METAL BENCHMARK PACK
//  No C ABI. No Python. No Rust. Just Kain + LLVM + inline metal.
//
//  Exercises every raw surface the language owns:
//    - Inline asm (`asm("pause")`, `asm("clflush ($0)", ptr)`)
//    - Raw memory ownership (`collapse`/`observe`/`decay`)
//    - CPU intrinsics (RDTSC, CPUID, prefetch, fences)
//    - Virtual memory management (vm_reserve/commit/protect/lock)
//    - Calling convention control (`@callconv("win64")`, `@callconv("vectorcall")`)
//    - Thread/CPU topology + affinity
//    - Shatter struct + ownership collapse
//    - Ephemeral local zero-init elision
//    - Converge fast lanes with inline asm paths
//    - Naked functions + section control
//    - Link-name extern declarations

//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)

//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array
//    buffer_view    — entangle buffer descriptor, read in zero-copy

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

// ============================================================================
// This pack is specialized for compiler diagnostics, not generic search.
// It keeps retrieval and diagnosis metadata together in one GPU path:
// - fused semantic score + top-k
// - lane-aware prefiltering
// - lane/code/repair consensus reduction
//
// Input corpus assumptions:
// - query/index embeddings are packed u8 vectors (dim=384 today)
// - each chunk has:
//     lane mask      (parse/type/borrow/effect/shader/world/import/... bits)
//     canonical code (hashed/packed diagnostic code id)
//     repair id      (hashed/packed fix strategy id)
// ============================================================================


// ============================================================================
// KERNEL 1 :: ErrorCorpusFusedDiagnoseTopK
// ============================================================================
// One launch does scoring and block-local top-k extraction while preserving
// diagnostic metadata for the selected winners.
//
// Block model:
// - 256 threads -> 8 warps
// - each warp scores one chunk stride lane
// - lane 0 in each warp publishes candidate tuple to storage scratch
// - warp 0 lane 0 merges candidates into block top-k

//                    KERNEL 1 :: SemanticFusedScoreTopK
// ============================================================================
// The crown jewel. Scores chunks via warp-parallel bit-overlap AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level popcount scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

//                    KERNEL 1 :: SemanticFusedScoreTopK
// ============================================================================
// The crown jewel. Scores chunks via warp-parallel byte matching AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// ============================================================================
// The crown jewel. Scores chunks via warp-parallel byte matching AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// Kain native LLVM proving ground.
//
// This file is deliberately broad and executable. It is the first file future
// agents should inspect after ARCHITECTURE.md and MEMORY.md when they need to
// remember that Kain is not only fn/if/let: it has compiler-owned intents,
// worlds, actors, native stdlib services, raw memory helpers, shaders, UI,
// graphics, process, net, fs, input, effects, and async values.
//
// Native LLVM truth for this checkout:
// - The executable lane below is compiled with `kain src/main.kn -t llvm`.
// - Live native code in this file now exercises enum `match`, numeric `for`
//   loops over `range`, `vec!`, `format!`, and `println` in addition to the
//   broader runtime and intent surface.
// - The ownership-memory lane demonstrates first-class `observe`, `collapse`,
//   and `decay` over both Kain heap regions and imported/local pointers.
// - Array `for`, receive, emit, user-defined macro expansion, and the more
//   exotic trait-dispatch corners remain deliberate backend proving targets.
// - Shader declarations are validated by the compiler and native graphics
//   runtime, while SPIR-V/PTX/CUDA artifact generation remains the GPU backend
//   lane rather than the primary focus of this example.

//  FUSION CHAIN — Kain Multi-Primitive Causal Chain Benchmark
// ============================================================================
//
//  This pack is the first benchmark to exercise deep causal chaining across
//  ALL of Kain's compiler-owned semantic primitives simultaneously:
//
//    world mutation
//      -> resonate fires (tripwire layer)
//         -> patch commits new state (mutation + journal layer)
//            -> entangle propagates to mirror (reactive sync layer)
//               -> pulse ticks observe mirror (realtime clock layer)
//                  -> actor receives ask() with live mirror value (concurrent layer)
//                     -> actor executes collapse/observe/decay (ownership layer)
//                        -> actor shatter-teleports payload (zero-copy layer)
//                           -> destination world receives result (world boundary)
//
//  NOTE: ask() accepts (actor_id, "MessageName", single_int_payload).
//  Multi-value payloads are packed into a single Int via bijective encoding
//  using modulus arithmetic. Actors decode the packed value internally.
//
//  Semantics exercised (all fused):
//    world, entangle, resonate, patch, law, converge, orchestrate,
//    actor, spawn, send, ask, pulse, shatter, teleport, collapse, observe, decay
//    + full std::intent telemetry across every layer
//
//  Cases:
//    0. fusion_resonate_actor_bridge    — resonate -> send -> actor acks
//    1. fusion_patch_entangle_ask       — patch -> entangle -> ask reads mirror
//    2. fusion_pulse_actor_teleport     — world tick -> actor teleports shard
//    3. fusion_full_causal_chain        — all 7 layers, one coherent scenario
//    4. fusion_resonate_reentrant_guard — resonate + actor + patch cycle, no deadlock
//    5. fusion_ownership_actor_bridge   — collapse/observe/decay inside actor handler
//    6. fusion_converge_actor_law       — actor uses converge fast lane + law check
//
//  Run focused:
//    $env:KAIN_BENCH_V2_FILTER="fusion_chain"
//    kain run X:\benchmark --target llvm --json

//
//  !! LANGUAGE SURFACE GAPS DISCOVERED DURING AUTHORING !!

//    continue return defer await in with as type struct enum trait impl pub
//    mod use self Self true false none and or

//  State: world entangle single_writer
//  Integrity: patch law
//  Dispatch: converge spec fast when target capability verify random
//  Stage Graph: orchestrate stage after deps residency transfer guarded by

//  No C ABI. No Python. No Rust. Just Kain + LLVM + inline metal.
//
//  Exercises every raw surface the language owns:
//    - Inline asm (`asm("pause")`, `asm("clflush ($0)", ptr)`)
//    - Raw memory ownership (`collapse`/`observe`/`decay`)
//    - CPU intrinsics (RDTSC, CPUID, prefetch, fences)
//    - Virtual memory management (vm_reserve/commit/protect/lock)
//    - Calling convention control (`@callconv("win64")`, `@callconv("vectorcall")`)
//    - Thread/CPU topology + affinity
//    - Shatter struct + ownership collapse
//    - Ephemeral local zero-init elision
//    - Converge fast lanes with inline asm paths
//    - Naked functions + section control
//    - Link-name extern declarations

//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)

//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

//  CORE_OS BENCHMARK PACK  —  Prove every std::os function talks to the real OS

//  inspect environment, check CPU topology, and bench the raw syscall path.

//  SEMANTIC OS: world/entangle/shatter accelerated path.
//  Instead of calling the kernel every iteration, we entangle OS values

// ============================================================================
//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)
//            ├── pi            math.pi
//            ├── sqrt_fn       math.sqrt reference
//            ├── floor_fn      math.floor reference
//            ├── sin_fn        math.sin reference
//            ├── cos_fn        math.cos reference
//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array
//    buffer_view    — entangle buffer descriptor, read in zero-copy
//
//  Run standalone:

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

// ============================================================================
// The crown jewel. Scores chunks via warp-parallel bit-overlap AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level popcount scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// The crown jewel. Scores chunks via warp-parallel byte matching AND finds

// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

//   - python_call_attr_raw(np, "linspace", ...)
//   - ~50 lines of raw bridge calls + info checking + conversion
//
// AFTER pykain (this file):
//   - import pykain as pykain
//   - pykain.tensor.grid(plan, seed)
//   - pykain.tensor.info(tensor)
//   - pykain.image.render(plan)
//   - pykain.validate.module("numpy")
//   - ~15 lines of clean, stable, backend-agnostic calls

//                    KERNEL 1 :: SemanticFusedScoreTopK
// ============================================================================
// The crown jewel. Scores chunks via warp-parallel byte matching AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// ============================================================================
// Kain native LLVM proving ground.
//
// This file is deliberately broad and executable. It is the first file future
// agents should inspect after ARCHITECTURE.md and MEMORY.md when they need to
// remember that Kain is not only fn/if/let: it has compiler-owned intents,
// worlds, actors, native stdlib services, raw memory helpers, shaders, UI,
// graphics, process, net, fs, input, effects, and async values.
//
// Native LLVM truth for this checkout:
// - The executable lane below is compiled with `kain src/main.kn -t llvm`.
// - Live native code in this file now exercises enum `match`, numeric `for`
//   loops over `range`, `vec!`, `format!`, and `println` in addition to the
//   broader runtime and intent surface.
// - The ownership-memory lane demonstrates first-class `observe`, `collapse`,
//   and `decay` over both Kain heap regions and imported/local pointers.
// - Array `for`, receive, emit, user-defined macro expansion, and the more
//   exotic trait-dispatch corners remain deliberate backend proving targets.
// - Shader declarations are validated by the compiler and native graphics
//   runtime, while SPIR-V/PTX/CUDA artifact generation remains the GPU backend
//   lane rather than the primary focus of this example.

//  CORE_OS BENCHMARK PACK  —  Prove every std::os function talks to the real OS
// ============================================================================
//  This is not a toy. Every function here calls the actual Windows/Linux kernel.
//  We create files, list directories, map memory, protect pages, lock RAM,
//  inspect environment, check CPU topology, and bench the raw syscall path.
//
//  SEMANTIC OS: world/entangle/shatter accelerated path.
//  Instead of calling the kernel every iteration, we entangle OS values
//  into a world cache — the runtime propagates updates automatically.
//
//  Run standalone:
//    kain run benchmark/cases_v2/core_os.kn --target llvm
//
//  Run via v2 router (after wiring):
//    $env:KAIN_BENCH_V2_FILTER="core_os"

//  METAL BENCHMARK PACK
//  No C ABI. No Python. No Rust. Just Kain + LLVM + inline metal.
//
//  Exercises every raw surface the language owns:
//    - Inline asm (`asm("pause")`, `asm("clflush ($0)", ptr)`)
//    - Raw memory ownership (`collapse`/`observe`/`decay`)
//    - CPU intrinsics (RDTSC, CPUID, prefetch, fences)
//    - Virtual memory management (vm_reserve/commit/protect/lock)
//    - Calling convention control (`@callconv("win64")`, `@callconv("vectorcall")`)
//    - Thread/CPU topology + affinity
//    - Shatter struct + ownership collapse
//    - Ephemeral local zero-init elision
//    - Converge fast lanes with inline asm paths
//    - Naked functions + section control
//    - Link-name extern declarations
//
//  Run standalone:
//    kain run benchmark/cases_v2/metal.kn --target llvm
//
//  Run via v2 router:
//    $env:KAIN_BENCH_V2_FILTER="metal"
//    kain run X:\benchmark --target llvm --json

//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)
//            ├── pi            math.pi
//            ├── sqrt_fn       math.sqrt reference
//            ├── floor_fn      math.floor reference
//            ├── sin_fn        math.sin reference
//            ├── cos_fn        math.cos reference
//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array
//    buffer_view    — entangle buffer descriptor, read in zero-copy
//

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

//                    KERNEL 1 :: SemanticFusedScoreTopK
// ============================================================================
// The crown jewel. Scores chunks via warp-parallel bit-overlap AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level popcount scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

//                    KERNEL 1 :: SemanticFusedScoreTopK
// ============================================================================
// The crown jewel. Scores chunks via warp-parallel byte matching AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

//   - python_call_attr_raw(np, "linspace", ...)
//   - ~50 lines of raw bridge calls + info checking + conversion
//
// AFTER pykain (this file):
//   - import pykain as pykain
//   - pykain.tensor.grid(plan, seed)
//   - pykain.tensor.info(tensor)
//   - pykain.image.render(plan)

// The crown jewel. Scores chunks via warp-parallel byte matching AND finds

// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// ============================================================================
// Kain native LLVM proving ground.
//
// This file is deliberately broad and executable. It is the first file future
// agents should inspect after ARCHITECTURE.md and MEMORY.md when they need to
// remember that Kain is not only fn/if/let: it has compiler-owned intents,
// worlds, actors, native stdlib services, raw memory helpers, shaders, UI,
// graphics, process, net, fs, input, effects, and async values.
//
// Native LLVM truth for this checkout:
// - The executable lane below is compiled with `kain src/main.kn -t llvm`.
// - Live native code in this file now exercises enum `match`, numeric `for`
//   loops over `range`, `vec!`, `format!`, and `println` in addition to the
//   broader runtime and intent surface.
// - The ownership-memory lane demonstrates first-class `observe`, `collapse`,
//   and `decay` over both Kain heap regions and imported/local pointers.
// - Array `for`, receive, emit, user-defined macro expansion, and the more
//   exotic trait-dispatch corners remain deliberate backend proving targets.
// - Shader declarations are validated by the compiler and native graphics
//   runtime, while SPIR-V/PTX/CUDA artifact generation remains the GPU backend
//   lane rather than the primary focus of this example.

//  CORE_OS BENCHMARK PACK  —  Prove every std::os function talks to the real OS
// ============================================================================
//  This is not a toy. Every function here calls the actual Windows/Linux kernel.
//  We create files, list directories, map memory, protect pages, lock RAM,
//  inspect environment, check CPU topology, and bench the raw syscall path.
//
//  SEMANTIC OS: world/entangle/shatter accelerated path.
//  Instead of calling the kernel every iteration, we entangle OS values
//  into a world cache — the runtime propagates updates automatically.
//
//  Run standalone:
//    kain run benchmark/cases_v2/core_os.kn --target llvm
//
//  Run via v2 router (after wiring):
//    $env:KAIN_BENCH_V2_FILTER="core_os"
//    kain run X:\benchmark --target llvm --json

//  METAL BENCHMARK PACK
//  No C ABI. No Python. No Rust. Just Kain + LLVM + inline metal.
//
//  Exercises every raw surface the language owns:
//    - Inline asm (`asm("pause")`, `asm("clflush ($0)", ptr)`)
//    - Raw memory ownership (`collapse`/`observe`/`decay`)
//    - CPU intrinsics (RDTSC, CPUID, prefetch, fences)
//    - Virtual memory management (vm_reserve/commit/protect/lock)
//    - Calling convention control (`@callconv("win64")`, `@callconv("vectorcall")`)
//    - Thread/CPU topology + affinity
//    - Shatter struct + ownership collapse
//    - Ephemeral local zero-init elision
//    - Converge fast lanes with inline asm paths
//    - Naked functions + section control
//    - Link-name extern declarations
//
//  Run standalone:

//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)
//            ├── pi            math.pi
//            ├── sqrt_fn       math.sqrt reference
//            ├── floor_fn      math.floor reference
//            ├── sin_fn        math.sin reference
//            ├── cos_fn        math.cos reference
//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array
//    buffer_view    — entangle buffer descriptor, read in zero-copy

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

// - query/index embeddings are packed u8 vectors (dim=384 today)

// - each warp scores one chunk stride lane
// - lane 0 in each warp publishes candidate tuple to storage scratch

// ============================================================================
// The crown jewel. Scores chunks via warp-parallel bit-overlap AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level popcount scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// ============================================================================
// The crown jewel. Scores chunks via warp-parallel byte matching AND finds

// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

// ============================================================================
// Kain native LLVM proving ground.
//
// This file is deliberately broad and executable. It is the first file future
// agents should inspect after ARCHITECTURE.md and MEMORY.md when they need to
// remember that Kain is not only fn/if/let: it has compiler-owned intents,
// worlds, actors, native stdlib services, raw memory helpers, shaders, UI,
// graphics, process, net, fs, input, effects, and async values.
//
// Native LLVM truth for this checkout:
// - The executable lane below is compiled with `kain src/main.kn -t llvm`.
// - Live native code in this file now exercises enum `match`, numeric `for`
//   loops over `range`, `vec!`, `format!`, and `println` in addition to the
//   broader runtime and intent surface.
// - The ownership-memory lane demonstrates first-class `observe`, `collapse`,
//   and `decay` over both Kain heap regions and imported/local pointers.
// - Array `for`, receive, emit, user-defined macro expansion, and the more
//   exotic trait-dispatch corners remain deliberate backend proving targets.
// - Shader declarations are validated by the compiler and native graphics
//   runtime, while SPIR-V/PTX/CUDA artifact generation remains the GPU backend
//   lane rather than the primary focus of this example.

// resonate_py_effects — modular effects engine authored in Kain semantics.
//
// This file proves Kain's compiler-owned semantic stack (world, entangle, law,
// patch, converge, orchestrate, pulse, resonate) against real-time audio effect
// authoring. Every construct is chosen because it maps to a genuine DSP concern:
//
//   world / entangle   → effect state authority + mirror for introspection
//   law                → parameter bounds as compile-witnessed invariants
//   patch              → journaled effect parameter mutation
//   converge           → DSP fast lanes (LFO shape, mixing, waveshaping)
//   orchestrate        → effect chain as typed stage graph
//   pulse              → LFO timing / modulation generator
//   resonate           → reactive dispatch when effect params change
//   collapse/observe   → owned buffer regions for delay-line memory
//
// Python owns audio rendering; Kain owns effect computation, state, and policy.

// ============================================================================
// std::kain — Compiler service API
//
// This module exposes the Kain compiler as a service, allowing Kain-authored
// tooling (LSP, formatters, analyzers, linters) to use the compiler's parser,
// typechecker, indexing, and formatting capabilities through a clean Kain API.
//
// Architecture:
//   Kain types (this file) → builtin bridge (crates/service-bridge) → service-api (crates/service-api)
//
// The bridge layer is registered in the Kain runtime via register_stdlib_extension.
// Complex results are returned as Value::Struct from builtins and destructured here.

// ============================================================================
//                          std::os  —  The Mothership OS Module
// ============================================================================
//  Zig-flavored OS substrate meets Python ergonomics.
//  Uses the 'import os' mental model: one module, everything the OS gives you.
//
//  Architecture:
//    Layer 0 ─ raw @extern ABIs (fs, process, machine, platform, runtime, time)
//    Layer 1 ─ this module: Python-like unified facade
//    Layer 2 ─ std::os::path (os_path.kn) for path manipulation
//
//  Usage:
//    use std::os
//    let cwd = os_getcwd()
//    let files = os_listdir(".")
//    let home = os_getenv("HOME")
//    os_makedirs("a/b/c")
//
//  Zig inspiration per X:\reference\zigos:
//    - Platform-specific raw bindings → os.linux.zig / os.windows.zig pattern
//    - Sub-modules for syscall/DLL imports → kernel32.zig, ntdll.zig
//    - Cross-platform posix layer atop raw os → our wrappers here
//    - Higher stdlib (fs, process, net) consume os as substrate

//  LESSONS LEARNED (from compiler feedback):
//    1. JSX {} can only reference: prop names, method calls, literals, operators.
//       _self is NOT in scope inside JSX. Use getter methods instead.
//    2. JSX for loop variables do NOT bind in the loop body.
//       Pre-compute arrays in methods, render lists differently.
//    3. JSX {/* */} comments do NOT exist. Use // outside render body.
//    4. JSX if conditions can only use method calls returning Bool or simple
//       identifiers -- no >, <, == operators inline.
//    5. weak state is actor-only, not component.
//    6. Component names cannot shadow builtin types (Void).
//
//  This file pushes every boundary the compiler allows.

// ============================================================================
//
//  This harness exercises the fuzz world and semantic constructs.
//  Components live in JSX only  --  they are NOT structs, you cannot
//  `let x = ComponentName(prop=val)`. They are used as:
//    - <ComponentName prop={value} /> in JSX
//    - world surface: surface native_ui => ComponentName
//
//  So this file focuses on what it CAN do: seed the world, fire patches,
//  verify entangle propagation, check law invariants, collect telemetry.

// ============================================================================
// The crown jewel. Scores chunks via warp-parallel byte matching AND finds
// top-k in the SAME kernel launch. No PCIe roundtrip for scores. No second
// kernel dispatch.
//
// Architecture: 256 threads/block = 8 warps. Warps 1-7 score chunks in
// parallel using the classic warp-level byte scan. Warp 0 serves as the
// DEDICATED MERGE ENGINE — it does not score; it reads each warp's best
// candidate and maintains the block's top-k in the output buffer.
//
// Flow per scoring cycle:
//   1. Warps 1-7 each score one chunk (warp-level byte scan)
//   2. Lane 0 of each warp writes (score, chunk_idx) to a warp scratch slot
//   3. Warp 0 reads all 7 scratch slots, inserts winners into block top-k
//   4. Repeat until all block chunks are processed
//
// Output: block_topk_indices[block_id*top_k + i], block_topk_scores[...]
// Host merges block results (typically <500 total candidates).

//  table, then runs them with structured reporting. If a module has no
//  registered tests, it's silently skipped — the template always compiles.

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  Layer 0: Plain fn, struct. No world/actor/entangle/patch/law.
//
//  Architecture:
//    - Each category module exports `get_tests() -> Array<TestCase>`.

//
//  Module-level mutable state is not supported in Kain — we use explicit
//  accumulator functions instead.

//  SPOOKYMAGIC.KN — SPOOKY CODEGEN BEHAVIORS
//
//  Models "spooky" codegen failures — Heisenbugs that only reproduce under
//  certain optimization levels, LLVM version-specific quirks, timing-dependent
//  IR emission failures, or gaps that produce subtly wrong output only when
//  specific compiler flags interact.
//
//  The 6 LLVM codegen gaps have varying degrees of "spookiness":
//
//    Gap 2 (py_getattr_raw):     Silent wrong data — worst kind (no crash)
//    Gap 3 (named destructure):  Only triggers on named-variant patterns
//    Gap 5 (return in match):    May be optimizer-level dependent
//    Gap 6 (break/continue PHI): Often O1/O2-only (O0 hides the bug)
//
//  IMPORTED BY: cause.kn, effect.kn
//  IMPORTS:      None (standalone — no circular dependencies)
//
//  PATTERN:
//    Use this file when:
//    - A codegen gap only reproduces at -O2 but not -O0
//    - Different LLVM versions produce different failure modes
//    - The emitted IR depends on function ordering or inlining decisions

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain codegen regression tests inside
//  an isolated subprocess, capturing stdout, stderr, and exit code for
//  deterministic inspection — essential for gaps that produce non-local
//  side effects (linker errors, LLVM crash dumps, or wrong data that doesn't
//  crash but corrupts subsequent output).
//
//  HOW IT WORKS:
//    1. Locates the codegen-edge-gaps binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  WHY ISOLATION MATTERS FOR CODEGEN GAPS:
//    - Gap 4 (ptr_to_int): linker errors crash the child, not the harness
//    - Gap 5 (return in match): LLVM assertion failures in child are captured
//    - Gap 6 (break/continue PHI): miscompilation at -O2 requires clean-room
//    - Gap 2/3 (silent wrong data): isolation prevents state leakage across tests
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  COMPONENT FUZZ -- A Plethora of Components Pushed to Breaking Point
// ============================================================================
//
//  LESSONS LEARNED (from compiler feedback):
//    1. JSX {} can only reference: prop names, method calls, literals, operators.
//       _self is NOT in scope inside JSX. Use getter methods instead.
//    2. JSX for loop variables do NOT bind in the loop body.
//       Pre-compute arrays in methods, render lists differently.
//    3. JSX {/* */} comments do NOT exist. Use // outside render body.
//    4. JSX if conditions can only use method calls returning Bool or simple
//       identifiers -- no >, <, == operators inline.
//    5. weak state is actor-only, not component.
//    6. Component names cannot shadow builtin types (Void).
//
//  This file pushes every boundary the compiler allows.

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  COMPONENT SURFACE PROOF — Regression test for Newsletter #2: Component Surface
// ============================================================================
//  COVERS:
//    - Newsletter #2: Component Surface — the `component` keyword reaches pixels
//    - Newsletter #3: Multi-Backend GPU Presenter — 18-slot vtable convergence
//    - Newsletter #4: Vulkan Rendering Pipeline — GPU backend routing
//    - component_surface.h: 18-slot KainComponentSurface trait
//    - native_ui_surface.c: native_ui surface backend
//    - component.rs: codegen vtable offsets 0-17
//    - window_proof/src/main.kn: the canonical 17-line proof
//    - window_proof/src/dashboard.kn: multi-component composition
//    - window_proof/src/world_read.kn: world state from component JSX
//
//  WHAT THIS PROVES:
//    1. Basic window proof — world + surface native_ui => Component works
//    2. World state reading from component JSX via WorldName.field
//    3. Multi-component composition (dashboard pattern) with 4+ components
//    4. Frame loop is emitted (surface_loop function in LLVM IR)
//    5. 18 vtable slots are all referenced in codegen
//    6. Component state persistence via state_get_i64 / state_set_i64
//
//  WHAT CHANGED (the regression surface):
//    - Codegen: compile_jsx rewrite (component.rs, 1150 lines)
//    - Codegen: vtable offsets 0-17 (was 0-14, added window_open + host_pump + session_attach_platform)
//    - C runtime: component_surface.c GPU backend routing via RENDERER_BACKEND env var
//    - C runtime: native_ui_surface.c auto-attaches winit host on session_create
//    - C runtime: native_ui_surface.c present now blits GDI framebuffer
//    - Merge: codegen calls through vtable instead of direct abi_ui_* functions
//    - Bug fix: state alloca PHI node (was uninitialized on frames 2+)
//    - Bug fix: state write-back loop (mutations were never persisted)
//    - Bug fix: sibling stable key indices (were all 0 due to reset inside loop)
//    - Bug fix: title attribute dropped by C backend (added to allowlist)
//
//  TELEMETRY GUARDS:
//    - patch_journal_count >= 0 (regression: world state mutation)
//    - entangle_propagation_count >= 0 (regression: world mirror sync)
//    - runtime_heap_validate() == 1 (regression: no memory corruption)
//    - component_surface_registry_count() >= 1 (regression: surface registered)
//    - native_ui_session_count() >= 0 (regression: session lifecycle)
//
//  KNOWN LIMITATIONS:
//    - GDI backend ignores element styles (background, color stored but not rendered)
//    - Component methods from {expr} produce runtime errors (_self not auto-passed)
//    - pulse runtime causes immediate process exit
//    - JSX if with operators (==, <, >) rejected by parser

//    - component_surface.c: resolve_gpu_backend() with getenv("RENDERER_BACKEND")
//    - vulkan_surface_shim.c: dlopen libkain-vulkan-abi.so pattern
//    - d3d12_surface_shim.c: LoadLibrary d3d12.dll pattern
//    - webgpu_surface_shim.c: dlopen libwgpu_native.so pattern
//    - HWND_GAP_RESOLUTION.md: GDI wins path when env var unset
//    - PHASE_0_ABI_RECONCILIATION.md: P0.1-P0.6 convergence
//    - IMPLEMENTATION_PLAN.md: Phase 0-6 layered architecture
//
//  WHAT THIS PROVES:
//    1. GDI path works when RENDERER_BACKEND is unset (default behavior)
//    2. RENDERER_BACKEND=vulkan routing is attempted (graceful degradation)
//    3. RENDERER_BACKEND=d3d12 routing is attempted
//    4. RENDERER_BACKEND=webgpu routing is attempted
//    5. Fallback to GDI when GPU unavailable
//    6. component_surface registry state is intact after GPU probe
//    7. 3 backend names are recognized by the registry
//
//  WHAT CHANGED (the regression surface):
//    - component_surface.c: +60 lines GPU backend routing
//    - vulkan_surface_shim.c: NEW — dlopen + capability probe + vtable fill
//    - d3d12_surface_shim.c: NEW — COM-based D3D12 backend shim
//    - webgpu_surface_shim.c: NEW — cross-platform WebGPU shim with WASM path
//    - stdlib_abi.c: +3 lines — auto-register native_ui surface
//    - HWND_GAP_RESOLUTION.md: Option D — GDI wins path for native_ui
//
//  KNOWN LIMITATIONS:
//    - Tests cannot verify actual Vulkan/D3D12/WebGPU backend without GPU hardware
//    - env var behavior tested indirectly via capability probes
//    - Actual swapchain creation requires physical GPU

//  STDLIB VULKAN PROOF — Regression test for Newsletter #4: std::vulkan Module
// ============================================================================
//  COVERS:
//    - Newsletter #4: Vulkan Rendering Pipeline — std::vulkan Kain module
//    - Newsletter #3: Stdlib wiring audit (73+ modules, 465+ @extern verified)
//    - stdlib/vulkan.kn: 170 lines, 9 public functions, 9 @extern declarations
//    - STDLIB_MAP.llm.md: 71 modules, 3644 public symbols, 4599 total
//    - STDLIB_EXTRA.md: C CONTRACT classification for vulkan module
//
//  WHAT THIS PROVES:
//    1. All 9 public functions are importable and typecheck
//    2. vulkan_available() returns valid result (0 or 1)
//    3. vulkan_set_uniform_time/resolution/mouse typecheck with Unsafe effect
//    4. vulkan_update_shader_uniforms composes the three setters
//    5. vulkan_read_spirv path resolution returns empty string when file absent
//    6. vulkan_last_error() and vulkan_present_count() wrappers work
//    7. All @extern symbols are linkable (don't produce "undefined symbol")
//
//  WHAT CHANGED (the regression surface):
//    - stdlib/vulkan.kn: NEW — 9 public functions, 5 raw @extern + 4 telemetry @extern
//    - Runtime: vulkan_abi.c new exported symbols (kain_vulkan_abi_load_shader,
//      kain_vulkan_abi_set_uniform)
//    - Component surface: GPU backend routing in component_surface.c
//    - Blade migration: 4 dead stubs deleted, chronosim bridge refactored
//
//  KNOWN LIMITATIONS:
//    - vulkan_load_shader requires a real Vulkan session (needs HWND + GPU driver)
//    - vulkan_read_spirv returns empty string when no .spv file exists
//    - Uniform set functions require Unsafe effect (manage raw memory)

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  VULKAN ABI PROOF — Regression test for Newsletter #3 & #4: Vulkan ABI Library
// ============================================================================
//  COVERS:
//    - Newsletter #3: Multi-Backend GPU Presenter — Vulkan ABI library architecture
//    - Newsletter #4: Vulkan Rendering Pipeline — 6 new rendering sections
//    - vulkan_abi.c: 3,520+ lines, sections 1-15 (dynamic loader, WSI surfaces,
//      device selection, swapchain, shader modules, graphics pipeline,
//      render pass, draw commands, descriptor sets, exported API)
//    - vulkan_abi.h: PFN typedefs, session state, exported symbols
//    - vulkan_loader_subset.h: 73 PFN prototypes (was 44, +29 for rendering pipeline)
//    - component_surface.c: GPU backend routing via RENDERER_BACKEND env var
//    - HWND_GAP_RESOLUTION.md: Architectural resolution for Vulkan window handle
//    - PHASE_0_ABI_RECONCILIATION.md: 3 ABI paths converged
//    - IMPLEMENTATION_PLAN.md: Phase 0-6 layered architecture
//
//  WHAT THIS PROVES:
//    1. DLL exports exist (kain_vulkan_abi_get_vtable, kain_vulkan_abi_load_shader,
//       kain_vulkan_abi_set_uniform)
//    2. 18-slot vtable is fillable with non-NULL function pointers
//    3. Capability probe (kain_vulkan_runtime_capability) returns 0/1 without crash
//    4. Graceful degradation when Vulkan not available (returns 0/false, not crash)
//    5. Vulkan telemetry globals (abi_vulkan_last_status, abi_vulkan_last_error)
//       are accessible and return valid data
//    6. Present counter and swapchain recreation counters are non-negative
//
//  WHAT CHANGED (the regression surface):
//    - vulkan_abi.c sections 10-15: +1,340 lines of rendering pipeline code
//    - vulkan_loader_subset.h: +29 PFN prototypes for rendering (vkCreateShaderModule
//      through vkGetBufferMemoryRequirements)
//    - vulkan_abi.h: +17 PFN typedefs, +10 session fields, +2 exported symbols
//    - component_surface.c: +60 lines GPU backend routing
//    - 3 GPU shims (vulkan/d3d12/webgpu) with dlopen patterns
//    - Blade migration: 4 dead stubs deleted (~428 lines), chronosim bridge
//      refactored (~300 lines smaller)
//
//  KNOWN LIMITATIONS:
//    - Vulkan window never Oracle-verified (no real GPU driver available in CI)
//    - Tests only verify ABI contract and graceful degradation
//    - Actual vkQueuePresentKHR path requires GPU hardware

//  RUNTIME LINKING TELEMETRY TESTS
//
//  Validates the Kain compiler's native C runtime linking pipeline:
//
//  ALREADY FIXED:
//    1. Consolidated link library lists into native_link::platform_link_libs()
//       — shell32, winhttp, advapi32, ws2_32, user32, gdi32, etc.
//    2. Fixed divergence between "kain run" and "kain build" code paths
//
//  NEEDS TESTS FOR REMAINING FIXES:
//    3. Wire "kain run" to use native_link::link_native_binary() instead of its
//       own inline clang invocation
//    4. Consolidate 5 different clang discovery implementations
//    5. Deprecate llvm_native_runtime_elision_decision() IR text scanner
//       (redundant with --gc-sections)
//
//  DESIGN PATTERN (per readme.md):
//    - Tests are registered in get_cause_tests() table
//    - Each test function returns 0 for pass, non-zero for fail
//    - use module imports symbols directly (no module prefix)
//    - Only use std::* imports (self-contained)

//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

// Kain native LLVM proving ground.
//
// This file is deliberately broad and executable. It is the first file future
// agents should inspect after ARCHITECTURE.md and MEMORY.md when they need to
// remember that Kain is not only fn/if/let: it has compiler-owned intents,
// worlds, actors, native stdlib services, raw memory helpers, shaders, UI,
// graphics, process, net, fs, input, effects, and async values.
//
// Native LLVM truth for this checkout:
// - The executable lane below is compiled with `kain src/main.kn -t llvm`.
// - Live native code in this file now exercises enum `match`, numeric `for`
//   loops over `range`, `vec!`, `format!`, and `println` in addition to the
//   broader runtime and intent surface.
// - The ownership-memory lane demonstrates first-class `observe`, `collapse`,
//   and `decay` over both Kain heap regions and imported/local pointers.
// - Array `for`, receive, emit, user-defined macro expansion, and the more
//   exotic trait-dispatch corners remain deliberate backend proving targets.
// - Shader declarations are validated by the compiler and native graphics
//   runtime, while SPIR-V/PTX/CUDA artifact generation remains the GPU backend
//   lane rather than the primary focus of this example.

//  RateLimiter uses a sliding-window algorithm. Each client key is tracked

//  runtime token list with add/revoke operations.
//
//  BACKPRESSURE (v0.2):
//    Under DDoS at 100K req/s, the RateLimiter's bounded mailbox (default 256)
//    saturates in microseconds. Callers should check actor_is_running(limiter_id)
//    before dispatching. If the rate limiter is unreachable, the router should
//    respond 503 immediately rather than queueing into a saturated mailbox.
//    This pushes rejection to the OS boundary (TCP connection refused / RST).

//  router.kn — HTTP Router Actor (v0.2)
//
//  Ladder: Layer 7 — Systems (actor)
//  Receives raw HTTP payloads, parses method/path/body, matches against
//  registered routes, dispatches to handler actors, and tracks telemetry.
//
//  BACKPRESSURE PATTERN (v0.2):
//    When dispatching to gateway actors (RateLimiter, AuthGate), the router
//    should check whether the target actor is reachable before forwarding.
//    The recommended pattern for v0.2+ implementations:
//
//      1. Use actor_is_running(gateway_id) to check liveness.
//      2. If the gateway is unreachable or actor_scheduler_queue_depth()
//         exceeds a threshold, respond with HTTP 503 immediately.
//      3. This pushes rejection to the OS boundary (TCP RST / connection
//         refused) rather than saturating the actor mailbox.
//
//  Dependencies:
//    types.kn  — RouteEntry, GreebleConfig, HttpRequest
//    state.kn  — ServerAuthority, ServerMirror, increment_requests

//  FUSION CHAIN — Kain Multi-Primitive Causal Chain Benchmark
// ============================================================================
//
//  This pack is the first benchmark to exercise deep causal chaining across
//  ALL of Kain's compiler-owned semantic primitives simultaneously:
//
//    world mutation
//      -> resonate fires (tripwire layer)
//         -> patch commits new state (mutation + journal layer)
//            -> entangle propagates to mirror (reactive sync layer)
//               -> pulse ticks observe mirror (realtime clock layer)
//                  -> actor receives ask() with live mirror value (concurrent layer)
//                     -> actor executes collapse/observe/decay (ownership layer)
//                        -> actor shatter-teleports payload (zero-copy layer)
//                           -> destination world receives result (world boundary)
//
//  NOTE: ask() accepts (actor_id, "MessageName", single_int_payload).
//  Multi-value payloads are packed into a single Int via bijective encoding
//  using modulus arithmetic. Actors decode the packed value internally.
//
//  Semantics exercised (all fused):
//    world, entangle, resonate, patch, law, converge, orchestrate,
//    actor, spawn, send, ask, pulse, shatter, teleport, collapse, observe, decay
//    + full std::intent telemetry across every layer
//
//  Cases:
//    0. fusion_resonate_actor_bridge    — resonate -> send -> actor acks
//    1. fusion_patch_entangle_ask       — patch -> entangle -> ask reads mirror
//    2. fusion_pulse_actor_teleport     — world tick -> actor teleports shard
//    3. fusion_full_causal_chain        — all 7 layers, one coherent scenario
//    4. fusion_resonate_reentrant_guard — resonate + actor + patch cycle, no deadlock
//    5. fusion_ownership_actor_bridge   — collapse/observe/decay inside actor handler
//    6. fusion_converge_actor_law       — actor uses converge fast lane + law check
//
//  Run focused:
//    $env:KAIN_BENCH_V2_FILTER="fusion_chain"
//    kain run X:\benchmark --target llvm --json

//    - Raw memory ownership (`collapse`/`observe`/`decay`)
//    - CPU intrinsics (RDTSC, CPUID, prefetch, fences)
//    - Virtual memory management (vm_reserve/commit/protect/lock)

//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)
//            ├── pi            math.pi
//            ├── sqrt_fn       math.sqrt reference
//            ├── floor_fn      math.floor reference
//            ├── sin_fn        math.sin reference
//            ├── cos_fn        math.cos reference
//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array
//    buffer_view    — entangle buffer descriptor, read in zero-copy

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

//  orchestrator.kn — MarkScript VM embedding for compiler orchestration
//  STREAM: CHARLIE
//  Consumed by: GOLF (as orchestration entry point)
//
//  This file embeds the markscript VM into the self-host compiler. It:
//    1. Creates and configures the markscript VM
//    2. Registers 9 compiler-specific IVT handlers (IDs 200-208)
//    3. Loads build config from markscript tables in build.md
//    4. Executes build pipelines defined in buildex.md
//    5. Provides CLI entry points for GOLF's cli.kn / main.kn
//
//  ALL handlers are STUBS — they return 0 (success) and print diagnostics.
//  GOLF wires them to real compiler functions in Wave 4.
//
//  Ladder rung: Layer 0 (fn) — plain orchestration module.
//  The heavy lifting is done by markscript (embedded VM).
//
//  Markscript API contract: EXACTLY 20 public functions from std::markscript.
//  No internal markscript calls, no direct VM field access.

// ═══════════════════════════════════════════════════════════════════
// Three-Layer Stdlib Pattern (Reference)
// ═══════════════════════════════════════════════════════════════════
//
// Layer 1: @extern fn abi_X(...)    — raw ABI declaration, emits LLVM declare
// Layer 2: pub fn native_X(...)     — thin wrapper, interpreter-interceptable
// Layer 3: pub fn X(...)            — versioned, documented public API
//
// Example:
//   @extern fn abi_runtime_init() -> Int
//   pub fn native_runtime_init() -> Int:
//       return abi_runtime_init()
//   pub fn runtime_init() -> Int:
//       return native_runtime_init()
//
// The `native_` layer exists because the interpreter cannot call @extern
// functions directly — it needs a Rust-native implementation. The native_X
// function acts as a dispatch point: the interpreter provides a native stub,
// while the LLVM codegen inlines through to the raw abi_X call.

//       state <field>: <Type> = <init_expr>
//       surface <kind> => <Component>
//

//   - State slots (name + type + initializer)
//   - At least one surface binding (native_ui, web, viewport3d, ue5)
//   - A struct-like type for dotted access (WorldName.field)
//   - Entangle coupling support (via knc_check_entangle)
//
// Phase 1 will add:
//   (A) State slot resolution: for each `state <name>: <Type> = <init>`:
//       - Resolve <Type> via resolve_type_in_env()
//       - Infer <init_expr> type via infer_expr_type()
//       - Call ensure_type_compatible() for init/decl match
//       - Register field name + type in env for WorldName.field access
//   (B) Surface validation: if surface_count == 0,
//       push diagnostic "world 'X' must declare at least one surface"
//   (C) World registration: struct type via declare_named_type()
//       and val binding for dotted access
//   (D) World metadata tracking: world_names, world_field_names,
//       world_field_types parallel arrays in TypeEnv

//   collapse/observe/decay — explicit raw pointer lifecycle (ownership state machine)
//   share/fanout — safe parallel write lanes

// Imports from types.kn, ast.kn for shared constants/structs.
// No local duplicates — all types resolved from the self-host workspace.

//   2. RegionPolicy table gates which operations are allowed per memory region
//   3. ActorContract types hold parsed actor definitions
//   4. check_actor()/check_collapse()/check_observe()/check_decay()

//   Q2: What's the relationship between component, render, std::ui, desktop?
//   Q3: What's the path from .kn file to pixel on screen?
//
// Ladder choices:
//   - component (Layer UI): reusable UI widget with typed props, state, methods, JSX render

//   - patch (Layer 2): journaled world mutation

// ── TEST 1: Standalone component -- no world, no surface ──────────────────
// A component is a FIRST-CLASS language declaration. It does NOT need a world
// to exist. However, without a world+surface OR a framework like Kaintana
// to host it, the component is a data declaration that produces a JSX tree
// when the compiler lowers it -- but has no runtime host to render pixels.

component HelloWidget():

        </stack>
    </panel>

// ── TEST 2: World + surface => component ───────────────────────────────────
// A world is the STATE AUTHORITY. The `surface native_ui => ComponentName`
// declaration tells the runtime: "Project this component as the native UI
// surface." This is the canonical world→UI wiring path.

// ─── Kaintana Screenshot Utility ─────────────────────────────────────────────
// Auto-snapshot the desktop UI to timestamped BMP files.
//
// Layer 0  — Pure utility (fn, struct).  No world / entangle / patch coupling.
//            The screenshot utility is a thin wrapper around the existing
//            kaintana_native_desktop_write_bmp / kaintana_desktop_host_write_screenshot_path
//            extern that renders the current GDI scene into a BMP file.
//
// Design notes:
//  • Screenshot captures the CURRENT frame that was already rendered via
//    kaintana_render_scene() — call AFTER kaintana_commit_frame() or
//    during the render phase.
//  • Filenames are unique per millisecond so no global counter is needed.
//  • Zero dependency on kaintana.kn — only imports types and the desktop adapter.
//  • Works with headless mode when the desktop bridge is probed.

//  RUN SMOKETEST — Markscript-Driven Three-kn Test Runner
//
//  Loads the 4 markscript .md test scripts, registers 25+ three-kn-specific
//  IVT handlers (IDs 200-240), executes each script through the MarkScript VM,
//  validates table data, and reports PASS/FAIL results.
//
//  Architecture:
//    import "three.kn" as three     ← three-kn capsule (276 KB, 19 modules)
//    use std::markscript            ← MarkScript VM embedding API
//    use lexer/parser/vm/bridge     ← markscript internals
//    Handler IDs: 200-240           ← three-kn bridge handlers
//    register_three_kn_handlers()    ← maps intent phrases → handler IDs
//    run_test_file(path)            ← load .md → compile → execute → validate
//    main()                         ← orchestrator
//
//  Verification:
//    cd X:/blades/markscript && kain check smoketest/run_smoketest.kn
//    cd X:/blades/markscript && kain run smoketest/run_smoketest.kn

//  MARKSCRIPT BRIDGE — Generic name-based IVT handler registry
//
//  Replaces the old 6-handler hardcoded dispatch with a name-based registry
//  that can map any Kain stdlib function to an intent phrase. The registry
//  is a compile-time const table — function-name-hash → function-ID.
//  The IVT (on the VM) maps intent-phrase-hash → function-ID. Dispatch
//  iterates over function-ID to call the correct Kain stdlib function.
//
//  Twelve built-in handlers (original 6 + 6 new stdlib bridges):
//    FN_FS_READ_TEXT=1      — read file "path"
//    FN_FS_WRITE_TEXT=2     — write file "path" "content"
//    FN_FS_EXISTS=3         — file exists "path"
//    FN_PROCESS_OUTPUT=4    — run "command"
//    FN_PROCESS_SPAWN=5     — spawn "command" (full process API)
//    FN_IMPORT_KAIN=6       — import kain "module"
//    FN_ASSERT=7            — assert value expected
//    FN_PRINTLN=8           — print value
//    FN_STR=9               — str(value) → string
//    FN_LEN=10              — len(string) → int
//    FN_PUSH=11             — push value to vm stack
//    FN_POP=12              — pop value from vm stack
//

//  cli.kn — MarkScript CLI argument parser and dispatcher
//
//  Design follows tree-kn's proven pattern:
//    get_user_args() → strips argv[0], returns clean Array<String>
//    parse_args()    → flag + subcommand parsing → MksConfig
//    usage()         → clap-like help text, exit codes, subcommands
//
//  Ladder: Layer 0 — plain fn with Pure effect. No world, no actor.
//  Just CLI hygiene that translates argv into a typed config struct.
//
//  Subcommands:
//    run <file>       Compile and execute (default)
//    check <file>     Compile-only, validate, no VM execution
//    disasm <file>    Disassemble bytecode dump
//    repl             Interactive REPL mode
//    eval <intent>    One-shot intent execution
//    init <name>      Scaffold a new markscript project
//    handlers         List registered IVT handlers
//    doc <file>       Render as clean documentation (strip VM output)
//
//  Exit codes:
//    0   — success
//    1   — usage/help shown
//    2   — file not found, parse error, runtime error
//    3   — unknown subcommand or flag

//  Usage:
//    mks run base.md prod.md    # prod overrides base
//    mks run base.md dev.md     # dev overrides base
//
//  Merge rules:
//    - Same-name tables: overlay rows APPEND to base (unless @replace)
//    - Same-name routines: overlay REPLACES base
//    - Same-name domains: MERGED (routines from both)
//    - @replace annotation: overlay table REPLACES base table entirely
//
//  Ladder rung: Layer 0 (fn) — table merging is a pure data operation.

//  MARKSCRIPT RUNTIME ENGINE DRIVER 1.0
//  CLI, disassembler, import resolution, execution pipeline, handler dispatch.
//
//  Entry point for the Markscript VM. Reads a .md file (or REPL input),
//  resolves @import directives, lexes, compiles to bytecode, and executes
//  through the stack VM. Supports the pause/resume handler dispatch pattern:
//    execute_bytecode → handler_id > 0 → dispatch → resume_execution → loop
//
//  Usage (see cli.kn for full subcommand reference):
//    mks run <file.md>           — compile & execute (default)
//    mks check <file.md>         — compile-only validation
//    mks disasm <file.md>        — show bytecode only
//    mks repl                    — interactive intent prompt
//    mks eval '<intent>'         — one-shot intent
//    mks init <name>             — scaffold project
//    mks handlers                — list IVT handlers
//    mks doc <file.md>           — render clean documentation
//    mks --help                  — show full usage

//  MARKSCRIPT UI BRIDGE — UI Event Binding Layer (DELTA)
//
//  Connects markscript intents to Kain UI events. Bridges the gap between
//  markscript's prose-based intent system and real widget event callbacks.
//
//  Architecture:
//    1. Create an MksUISession with a markscript VM and UI session
//    2. Load a .md spec file to extract widget tree, layout, presets, etc.
//    3. Create real Kain UI widgets from markscript table data
//    4. Bind widget events to markscript routine dispatches
//    5. When a UI event fires, push event data into VM, dispatch intent,
//       and run the markscript routine
//
//  Ladder rung: Layer 0 (fn) — plain module. Uses world/entangle only
//  if the session needs reactive state sync, but the initial implementation
//  is imperative.
//
//  Value semantics throughout.

//    Interpreter VM (execute_bytecode):
//      HALT (0) returns the accumulator register — which is only updated
//      by OP_POP_STACK (8).  All arithmetic ops write to the operand stack,
//      NOT the accumulator.

//      HALT (0) pops the top of the RBP-relative operand stack into RAX
//      and returns it.  This is the only way to extract a result.
//
//    For equivalence comparisons we therefore compare:
//      VM  → er.vm.stack[last].int_val  (top of operand stack)
//      JIT → call_jit() return value    (top of JIT operand stack at HALT)

//  KAINOS COMPAT — File Descriptor Table (per-ProcessCompatActor)
//
//  Each Linux process has an FD table mapping integer FDs to kernel objects.
//  FDs can be: file, socket, pipe, epoll, eventfd, timerfd, signalfd.
//  FD flags: O_CLOEXEC (close-on-exec), O_NONBLOCK.
//  Cloning for fork/clone with CLONE_FILES flag.
//
//  Uses a sentinel-based approach: free_slots[i] tracks whether entries[i]
//  is occupied, avoiding the need for Array<Option<T>> (which Kain typechecks
//  differently from Rust).

//  KAINOS COMPAT — WINE/Proton Bridge
//
//  WINE runs on top of PosixActor. This module provides:
//  - Windows PE loader stubs (map .text/.data/.rdata/.bss sections)
//  - ntdll → PosixActor syscall interface
//  - GPU passthrough: WINE→DXVK→Vulkan→Kain native GPU
//  - Window management: WINE windows → KAINOS compositor
//
//  Phase 4 component — stubbed for now. The architecture is documented
//  per kainos-compatibility-bridge.md: WINE builds on PosixActor, GPU
//  is fully native (no VM), windows integrate with the Kain compositor.
//
//  References: compat/ spec, kainos-compatibility-bridge.md

//  KAINOS KERNEL — Resonate Interrupt Subsystem (kernel/resonate.kn)
// ============================================================================
//  Stream: B | Layer 5: Temporal — Interrupt → actor message dispatch via resonate
//
//  In KAINOS, interrupts are NOT handled by traditional ISRs. Instead, each
//  IRQ line is mapped to a world state field. When the interrupt fires, the
//  IDT stub writes to the world field, the resonate tripwire detects the
//  change, and the handler dispatches an actor message to the appropriate
//  device actor.
//
//  This eliminates the entire class of top-half/bottom-half bugs:
//    - No interrupt handler runs in arbitrary context
//    - No shared state between interrupt and scheduler context
//    - Interrupts become messages in actor mailboxes
//    - Dampening absorbs interrupt storms
//
//  Architecture:
//    Hardware IRQ → IDT stub → irq_handler(vector)
//      → set DeviceWorld.irq_pending[irq] = true
//      → send EOI to APIC
//      → resonate DeviceWorld.irq_pending on change fires
//        → handler identifies IRQ source
//        → dispatches message to appropriate actor
//        → clears irq_pending
//
//  Dependencies: arch/x86_64/apic.kn, arch/x86_64/idt.kn, panic.kn, pulse.kn
//  Delivers to: all device actors (interrupt dispatch)

//  mm/heap.kn. No libc malloc/free needed.

//  Each extension is a .md file compiled via std::mks with JIT.

//    - A Metadata table with extension properties
//    - Command tables defining slash commands
//    - Tool tables defining available tools
//    - Blockquote intents handling command execution
//    - Fenced code blocks for markscript logic
//
//  Ladder:
//    Layer 0 — fn + struct for loading logic
//    Layer 7 — actor for managing loaded extensions (planned)
//
//  Integration with commands.kn:
//    load_extension() reads the .md tables and produces Extension structs.
//    The CommandRegistry actor in commands.kn registers the commands.
//    Dispatch routes back to the extension's VM for execution.

//  render loop (commented-out template for v0.1), differential frame
//  comparison (only writes changed lines to stdout), full-frame rendering
//  (on resize), and the status/footer line formatter.
//
//  Ladder:
//    Layer 5 (temporal) — `pulse tui_render_loop every 16ms` drives the
//      frame schedule. This is the canonical temporal beat: the compiler
//      owns timing, jitter, and missed-beat tracking.
//    Layer 0 — `fn` for pure computation (diffing, formatting, cursor
//      extraction). These are stateless transforms consumed by the pulse.
//
//  MarkScript: The pulse render loop is the markscript-equivalent of a
//  reactive display pipeline — markscript's `@every` decorator drives
//  markdown-to-bytecode rendering at a configurable interval. Here the
//  same pulse-driven reactive display pattern is expressed in native Kain,
//  with the compiler owning timing via `pulse` instead of a decorator.
//  std::mks config tables can supply runtime overrides for frame interval,

// resonate_py_effects — modular effects engine authored in Kain semantics.
//
// This file proves Kain's compiler-owned semantic stack (world, entangle, law,
// patch, converge, orchestrate, pulse, resonate) against real-time audio effect
// authoring. Every construct is chosen because it maps to a genuine DSP concern:
//
//   world / entangle   → effect state authority + mirror for introspection
//   law                → parameter bounds as compile-witnessed invariants
//   patch              → journaled effect parameter mutation
//   converge           → DSP fast lanes (LFO shape, mixing, waveshaping)
//   orchestrate        → effect chain as typed stage graph
//   pulse              → LFO timing / modulation generator
//   resonate           → reactive dispatch when effect params change
//   collapse/observe   → owned buffer regions for delay-line memory
//
// Python owns audio rendering; Kain owns effect computation, state, and policy.

// ============================================================================
// This file proves the pykain ergonomic win.
//
// BEFORE pykain (see 1_pygame_mcp.kn):
//   - import numpy as np, import torch as torch, import pygame as pygame
//   - import python_lab.bridge as py_lab
//   - from python_lab.bridge import tensor_signature, module_digest, ...
//   - use std::python, use std::interop
//   - python_call_attr_raw(py_lab, "make_numpy_grid", ...)
//   - python_call_attr_raw(np, "linspace", ...)
//   - ~50 lines of raw bridge calls + info checking + conversion
//
// AFTER pykain (this file):
//   - import pykain as pykain
//   - pykain.tensor.grid(plan, seed)
//   - pykain.tensor.info(tensor)
//   - pykain.image.render(plan)
//   - pykain.validate.module("numpy")
//   - ~15 lines of clean, stable, backend-agnostic calls
//
// The Kain side shrinks. The Python side absorbs all the normalization.
// Every new Kain+Python script starts from pykain, not from raw bridge calls.

// vkvg.kn — Kain facade over vkvg_bridge (Vulkan Vector Graphics)
//
// Pattern: src/bridge/clap_host.kn — wraps native C bridge for Kain consumption.
//
// vkvg (Vulkan Vector Graphics) is a Cairo-like 2D drawing library with Vulkan
// hardware acceleration. This facade wires it into reson8's UI rendering pipeline,
// replacing the std::ui "software" (GDI) backend with GPU-accelerated 2D vector art.
//
// The bridge expects an existing Vulkan context (use std::graphics / Vulkan ABI library).
//
// Usage:
//   let dev = vg_init(vk_instance, vk_phy, vk_dev, qfi, qi, 1)
//   let surf = vg_surface_new(WIN_W, WIN_H)
//   let ctx = vg_context_new(surf)
//   vg_set_rgba(ctx, 0.1, 0.1, 0.18, 1.0)
//   vg_rect(ctx, 0.0, 0.0, WIN_W, WIN_H)
//   vg_fill(ctx)

//  SECTION 1  —  BuildContext (read-only, injected by the compiler)
// ============================================================================
//  The `ctx` parameter is injected by the Kain compiler at build time.
//  You can read its fields but should NOT modify them.

//         .member("blades/tools")

// ============================================================================
//  SECTION 3  —  PACKAGE SPEC
// ============================================================================
//  Declare a named package with version and description.  Used alongside
//  blade() when you want to distinguish the package identity from the blade
//  definition.  For most projects, project() (Section 5) does both at once.

// ============================================================================
//  SECTION 4  —  BLADE SPEC
// ============================================================================
//  A blade is a buildable unit: entry point, source roots, module roots,
//  build targets, and inter-blade dependencies.
//
//     let blade_spec = blade("my-blade")

// ============================================================================
//  SECTION 5  —  PROJECT SPEC  (shorthand for package + blade)
// ============================================================================
//  project() creates both a PackageSpec and a BladeSpec at once when you
//  call build_graph().project(app).  This is the MOST COMMON pattern.
//
//     let app = project("my-project")
//         // ── Identity ──

// ============================================================================
//  SECTION 7  —  RUN DEFAULTS
// ============================================================================
//  Settings for `kain run` execution, including watch mode paths.
//
//     let run = run_defaults()
//         .entry("src/main.kn")                 // Default entry for run

//         .watch("KAIN.toml")

// ============================================================================
//  SECTION 8  —  SOURCE SETS
// ============================================================================
//  Named collections of source files.  Used to group inputs for tasks
//  without repeating file lists.  Supports globs, explicit files, and
//  exclude patterns.
//
//     // ── Simple glob source set ──
//     let all_sources = source_set("all-sources")

//
//     // ── Source set including non-Kain files ──

//         .file("config.json")
//         .file("build.kn")

// ============================================================================
//  SECTION 9  —  PLATFORM PACKAGES
// ============================================================================
//  External platform/SDK dependencies like Vulkan, CUDA, Win32, etc.
//  These are resolved at build setup time, not at runtime.
//
//     let vk = platform_package("vulkan")

// ============================================================================
//  SECTION 10  —  CHECK TASKS (typecheck only, no codegen)
// ============================================================================
//  build_check() / check_task() — typecheck one or more files.  Fastest

// ============================================================================
//  SECTION 22  —  ADVANCED / UNDOCUMENTED FEATURES
// ============================================================================
//  These features are supported by the Rust build evaluator (crates/build/)
//  but NOT exposed in the std::build public API (stdlib/build.kn).
//
//  Use them at your own risk: they WILL work during `kain build`/`kain run`
//  but may produce type errors in `kain check` since the stdlib structs
//  don't have the matching impl methods.
//
//  ─── build_defaults() hidden methods (Rust evaluator supports these) ───
//    .entry_module("ModuleName")        Entry module (source module name, not path)
//    .source_root("src")                 Default source root
//    .source_order(["a.kn", "b.kn"])     Explicit source file order for compilation
//    .module_search_path("path")          Additional module search paths (repeatable)
//    .module_search_paths("path")
//
//  ─── run_defaults() hidden method ───
//    .blade("blade-name")               Run a specific blade's entry
//    .env("KEY", "value")               Environment variables for the run process
//    .cwd("$root")                      Working directory for the run process
//
//  ─── Task kind aliases not wrapped by std::build factories ───
//    These only work via build_task_of_kind(id, kind) or explicit tasks
//    in KAIN.toml:
//
//    build_task_of_kind("cargo-build", "cargo")
//        .command("cargo").arg("build")
//        .cwd("$root/my-rust-crate")

//
//    build_task_of_kind("bun-build", "bun")
//        .entry("scripts/build.ts")
//        .cwd("$root")
//
//  ─── Task dependency scoping ───
//    Cross-blade dependencies use "blade-name:task-id" syntax:
//      .requires("other-blade:check-llvm")
//      .depends_on("core-lib:build-lib")
//
//    This is how you reference a task that belongs to a different blade's
//    build graph.  The first part is the blade name, the second is the
//    task ID as declared in that blade's build.kn.

//  cli.kn — CLI argument parser and dispatcher for Kain starter projects
//
//  Design follows markscript's proven pattern:
//    get_user_args()  → portable argv wrapper (strips executable path)
//    parse_args()     → flag + subcommand parsing → CliConfig
//    usage()          → clap-like help text, exit codes, subcommands
//
//  Ladder: Layer 0 — plain fn with Pure effect. No world, no actor.
//  Just CLI hygiene that translates argv into a typed config struct.
//
//  Subcommands:
//    run <file>       Execute the default pipeline (default when <file> given)
//    check <file>     Validate and verify (compile-only)
//    help             Show this help message
//    version          Show version
//    exec <expr>      Execute a one-shot expression
//
//  Exit codes:
//    0   — success
//    1   — help or version shown (not an error)
//    2   — error — file not found, parse failure, runtime
//    3   — unknown subcommand or flag

//  VM.KN — ISOLATED PROCESS EXECUTION WRAPPER
//
//  Invoked via the --vm CLI flag. Runs Kain tests inside an isolated
//  subprocess, capturing stdout, stderr, and exit code for deterministic
//  inspection — even for black-box / Heisenbug errors.
//
//  HOW IT WORKS:
//    1. Locates the debug-template binary on disk
//    2. Spawns it as a child process with the same test name but without --vm
//    3. Captures stdout + stderr
//    4. Waits for exit and reports results
//
//  ADVANCED: For deeper isolation, import markscript's bytecode VM.
//    The markscript VM (X:\blades\markscript\src\vm.kn) provides a stack-based
//    bytecode executor with full IVT dispatch, typed arithmetic, and handler
//    chaining. To use it:
//      1. Copy markscript/src/vm.kn, types.kn, error.kn into this template
//      2. Compile your test logic to Markscript bytecode
//      3. Execute through execute_bytecode() for complete determinism

//  PYGAME TEMPLATE — Entry Point
// ============================================================================
//  Wires the semantic stack: probe -> seed -> bridge -> run -> validate.
//
//  PHASES:
//    1. Probe      - check pygame module is available
//    2. Pre-Sim    - warm up actors, exercise converge/orchestrate/pulse
//    3. Bridge     - register python_actor_callback, bind to __main__
//    4. Launch     - python_exec the Pygame bootstrap (BLOCKS)
//    5. Validate   - check world state, mirror propagation, telemetry deltas
//
//  ADDING STUFF:
//    - New actors?  Drop them in actors.kn and spawn in Phase 2.
//    - New scene?   Edit sprite_data in bridge.kn's inline Python.
//    - New state?   Add to world.kn: fields, entangles, laws, patches.
//    - New UI?      Drop a component in world.kn or ui.kn, compose in GameHUD.
//    - New pipeline? Add converge/orchestrate/pulse to pipeline.kn.

//  VULKAN TEMPLATE — Flyby Camera (Pure Math)
//  Ladder rung: Layer 0 (fn, struct) — pure math, no input dependencies.
//
//  The caller (main.kn) polls keyboard/mouse via Win32, computes movement
//  and look deltas, then passes them to the camera as pure parameters.
//
//  Camera orientation is stored as yaw+pitch angles (FPS-style).
//  Movement:
//    Input:  move_forward_dt (positive=forward, negative=back)
//            move_right_dt   (positive=right, negative=left)
//            move_up_dt      (positive=up, negative=down)
//            look_dx         (mouse horizontal delta, radians)
//            look_dy         (mouse vertical delta, radians)
//  Matrices:
//    view        = mat4_look_at(position, position + forward, world_up)
//    projection  = mat4_perspective(fov, aspect, near, far)
//    mvp         = projection * view

//  FUSION CHAIN — Kain Multi-Primitive Causal Chain Benchmark
// ============================================================================
//
//  This pack is the first benchmark to exercise deep causal chaining across
//  ALL of Kain's compiler-owned semantic primitives simultaneously:
//
//    world mutation
//      -> resonate fires (tripwire layer)
//         -> patch commits new state (mutation + journal layer)
//            -> entangle propagates to mirror (reactive sync layer)
//               -> pulse ticks observe mirror (realtime clock layer)
//                  -> actor receives ask() with live mirror value (concurrent layer)
//                     -> actor executes collapse/observe/decay (ownership layer)
//                        -> actor shatter-teleports payload (zero-copy layer)
//                           -> destination world receives result (world boundary)
//
//  NOTE: ask() accepts (actor_id, "MessageName", single_int_payload).
//  Multi-value payloads are packed into a single Int via bijective encoding
//  using modulus arithmetic. Actors decode the packed value internally.
//
//  Semantics exercised (all fused):
//    world, entangle, resonate, patch, law, converge, orchestrate,
//    actor, spawn, send, ask, pulse, shatter, teleport, collapse, observe, decay
//    + full std::intent telemetry across every layer
//
//  Cases:
//    0. fusion_resonate_actor_bridge    — resonate -> send -> actor acks
//    1. fusion_patch_entangle_ask       — patch -> entangle -> ask reads mirror
//    2. fusion_pulse_actor_teleport     — world tick -> actor teleports shard
//    3. fusion_full_causal_chain        — all 7 layers, one coherent scenario
//    4. fusion_resonate_reentrant_guard — resonate + actor + patch cycle, no deadlock
//    5. fusion_ownership_actor_bridge   — collapse/observe/decay inside actor handler
//    6. fusion_converge_actor_law       — actor uses converge fast lane + law check
//
//  Run focused:
//    $env:KAIN_BENCH_V2_FILTER="fusion_chain"
//    kain run X:\benchmark --target llvm --json

//  PYTHON SEMANTIC — World/Entangle accelerated Python interop
// ============================================================================
//  Rewrites the v1 PyO3/benchmark lanes with Kain's semantic caching.
//  The v1 benchmarks cross the Python bridge for every call — even when
//  calling the SAME function with the SAME arguments, or reading the SAME
//  module attribute that never changes.
//
//  The fix: entangle EVERYTHING permanent into a world cache.
//    - Module attribute lookups (__name__, tau, pi, sep) — one bridge hit ever
//    - Function references (math.sqrt, json.dumps, os.path.join) — one hit ever
//    - Constant call results (math.tau, sys.getdefaultencoding()) — one hit ever
//    - Numpy buffer views — entangle the shared memory descriptor, not the data
//
//  Architecture:
//    WorldPythonAuthority  ← seeded once from real Python
//            │
//            ├── tau           math.tau (constant)

//            ├── floor_fn      math.floor reference
//            ├── sin_fn        math.sin reference
//            ├── cos_fn        math.cos reference
//            └── buffer_view   shared numpy array descriptor
//            │
//    WorldPythonMirror  ← entangled reads = zero bridge crossings
//
//  Benchmarks:
//    hotloop_raw    — original v1 style: bridge crossing per iteration
//    hotloop_cache  — entangled cache: read once, iterate free
//    batch_sqrt     — precompute 4096 sqrts into entangled array
//    buffer_view    — entangle buffer descriptor, read in zero-copy

// ============================================================================
//  SEMANTIC PYTHON CACHE — World/Entangle accelerated Python interop
// ============================================================================
//  The problem: existing benchmark cases cross the Python bridge every
//  iteration to read values that NEVER change (module __name__,
//  sys.getdefaultencoding(), json.dumps([1,2,3]), os.sep, etc.).
//
//  The fix: entangle those constant results into a Kain world cache.
//  Once seeded, reads from the mirror are zero-copy field accesses
//  instead of Python bridge crossings.
//
//  This is exactly the same pattern as the semantic OS cache but
//  targets the Python bridge tax instead of the kernel call tax.

// ============================================================================
// component_composition.kn — DEEP COMPONENT NESTING (6 LEVELS)
// ============================================================================
//
// WHAT THIS PROVES:
//   1. Deep component nesting works: root → sidebar + content → section →
//      group → card → label + value. 6 levels of JSX composition.
//   2. All data flows from world state → top-level fns → JSX {expr}.
//   3. Components at different tree levels all read the same world.
//   4. The uppercase/lowercase tag dispatch: <ComponentName /> calls components,
//      <text /> / <stack /> / <panel /> are native elements.
//
// COMPOSITION TREE (6 levels):
//   LEVEL 0: PipelineDashboard  ← world surface
//   LEVEL 1: PipelineSidebar + PipelineContent
//   LEVEL 2: PipelineSection (inside PipelineContent)
//   LEVEL 3: StageGroup (inside PipelineSection)
//   LEVEL 4: StageCard (inside StageGroup)
//   LEVEL 5: StageLabel + StageValue + StageBar (inside StageCard)
//
// DOMAIN: CI/CD Pipeline Monitor — tracks build, test, and deploy stages.
//   Different from nested_dashboard.kn (server monitoring) to prove
//   the composition pattern is domain-agnostic.
//
// RULES FOLLOWED:
//   ✅ Top-level fns with explicit args (NOT component methods from JSX)
//   ✅ World state via WorldName.field
//   ✅ No pulse, no operators in JSX if
//   ✅ Self-contained with fn main()
// ============================================================================

// multi_surface.kn — DUAL-SURFACE WORLD (native_ui + web) WITH ONE COMPONENT
// ============================================================================
//
// WHAT THIS PROVES:
//   1. A single world can project the SAME component to multiple surface kinds.
//      The component author never knows or cares which backend renders it.
//
//   2. Surface-agnostic rendering: the same 18-slot KainComponentSurface vtable
//      works for `native_ui` (Win32 GDI or Vulkan GPU) and `web` (WASM browser).
//      The compiler emits the SAME vtable calls regardless of surface kind.
//
//   3. World state is shared across all surfaces. Mutate `MultiWorld.counter` and
//      both the native_ui AND web component views see the update.
//
// ARCHITECTURE:
//   MultiWorld
//     ├── surface native_ui => MultiDashboard
//     │     → kain_component_surface_resolve("native_ui")
//     │     → RENDERER_BACKEND routing (vulkan/d3d12/webgpu/gdi)
//     │     → frame loop A: MultiDashboard_render → GDI framebuffer or GPU swapchain
//     │
//     └── surface web => MultiDashboard
//           → kain_component_surface_resolve("web")
//           → WASM/JS canvas rendering (planned — web surface backend)
//           → frame loop B: MultiDashboard_render → HTML canvas
//
//   The SAME component render function (MultiDashboard_render) is called from
//   BOTH frame loops. The component's JSX tree is emitted through whichever
//   vtable the current surface backend provides.
//
// STATUS:
//   native_ui: ✅ Working (Win32 GDI, Oracle-verified)
//   web:       🔜 Planned (WASM target, web_surface backend)

// WHAT THIS PROVES:
//   1. The Vulkan ABI library exposes `kain_vulkan_abi_load_shader(hex)` and
//      `kain_vulkan_abi_set_uniform(binding, data, size)` for uniform updates.
//      This file is the Kain-side scaffold that matches that contract.
//
//   2. The uniform signature (time @0, resolution @1, mouse @2) matches the
//      shaders in blades/shaderlib/ (ocean.kn, blackhole.kn). The descriptor
//      set layout in the Vulkan ABI library has 3 uniform buffer bindings:
//        - Binding 0: Float (time)
//        - Binding 1: Vec2 (resolution)
//        - Binding 2: Vec2 (mouse)
//
//   3. The `surface vulkan => ShaderFragment` proposal from NEWSLETTER-4 would
//      auto-generate a frame loop that calls load_shader + set_uniform instead
//      of a component render function. Until that's implemented, this file shows
//      the COMPONENT-SIDE scaffold — a world with surface native_ui that displays
//      the shader uniforms as text, proving the data contract is correct.
//
// ARCHITECTURE (when surface vulkan => ShaderFragment is implemented):
//   Compiler emits for `surface vulkan => OceanFragment`:
//     1. Compile ocean.kn → SPIR-V hex at build time
//     2. surface = kain_component_surface_resolve("native_ui")
//          → RENDERER_BACKEND=vulkan routes to GPU shim
//     3. session_create + session_attach_platform
//     4. kain_vulkan_abi_load_shader(session, spirv_hex)
//          → vkCreateShaderModule(fragment SPIR-V)
//          → vkCreateGraphicsPipeline(embedded VS + fragment)
//          → vkCreateRenderPass + vkCreateFramebuffer per swapchain image
//          → vkCreateDescriptorSetLayout(time/resolution/mouse)
//          → vkAllocateDescriptorSets + vkUpdateDescriptorSets
//     5. LOOP:
//          set_uniform(0, &time, 4)      // Float
//          set_uniform(1, &resolution, 8) // Vec2
//          set_uniform(2, &mouse, 8)      // Vec2
//          begin_frame → vkCmdDraw(3) → end_frame → present
//
// HOW TO RUN (current component scaffold, renders uniforms as text):
//   kain build src/shader_host.kn --target llvm && .kain/out/shader_host.exe
//
// HOW TO RUN (future 〰 when surface vulkan => ShaderFragment lands):
//   $env:RENDERER_BACKEND = "vulkan"
//   kain build src/shader_host.kn --target llvm && .kain/out/shader_host.exe
//   # The ocean.kn shader renders through the GPU fullscreen triangle

//   - Binding 1: VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER at VK_SHADER_STAGE_FRAGMENT_BIT
//   - Binding 2: VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER at VK_SHADER_STAGE_FRAGMENT_BIT
// The 4th uniform (StorageBuffer<Float> @3) is a padding trick — it forces
// descriptor-based binding instead of push constants. See NEWSLETTER-1 §5.

// ============================================================================
// ============================================================================
// theme_demo.kn — THEME SYSTEM IN USE (Login Shell + App Dashboard)
// ============================================================================
//
// WHAT THIS PROVES:
//   1. Theme values (colors, spacing, fonts, radii) stored as world state
//      flow through EVERY component in the tree — not just a showcase.
//   2. Multiple independent components (LoginScreen, AppHeader, ProfileCard,
//      StatusBadge, ActionButton, MetricsRow) all read the SAME ThemeWorld.
//   3. Changing one world field updates ALL components simultaneously.
//   4. Themes are NOT just display values — they're the DESIGN SYSTEM that
//      every component references for layout and typography decisions.
//
// DIFFERENCE FROM theme_showcase.kn:
//   theme_showcase.kn DISPLAYS theme values (palette, spacing scale, etc.)
//   theme_demo.kn USES theme values (login form, app header, profile cards)
//   This proves themes are practical infrastructure, not just a style guide.
//
// THEME WORLD FIELDS:
//   5 semantic colors (primary, surface, text, muted, accent)
//   4 spacing tokens (xs, sm, md, lg)
//   4 font sizes (sm, md, lg, xl)
//   2 semantic colors (success, danger)
//   Total: 15 theme fields driving 8 components
//
// RULES FOLLOWED:
//   ✅ Top-level fns with explicit args (NOT component methods from JSX)
//   ✅ World state via ThemeWorld.field
//   ✅ No pulse, no operators in JSX if
//   ✅ Self-contained with fn main()

// THEME WORLD — the single source of truth for all styling

// WHY world: Theme values must be readable from every component in the tree.
// World is the compiler-owned state container that all components can access
// via ThemeWorld.field in JSX {expr}. Change one field here and every
// component that reads it updates on the next frame.
//
// WHY 15 fields: A real design system has colors, spacing, typography, and
// semantic tokens. This is a minimal but complete set.

//
// WHAT THIS PROVES:
//   1. Every `world` + `surface native_ui => Component` program is ALREADY
//      Vulkan-ready. Set RENDERER_BACKEND=vulkan and the component surface
//      registry routes `native_ui` to the libkain-vulkan-abi.so vtable.
//      Zero source changes. Same 18 vtable slots, different backend.
//
//   2. World state can be read from JSX {expr} via `WorldName.field`.
//
//   3. Top-level formatting functions (NOT component methods) can be called
//      from JSX {expr} — this is the proven working pattern.
//
// ARCHITECTURE (what happens at runtime):
//   RENDERER_BACKEND=vulkan:
//     kain_component_surface_resolve("native_ui")

//       → 18-slot KainComponentSurface vtable filled

//     LOOP:
//       begin_frame → vkAcquireNextImageKHR → vkCmdBeginRenderPass
//       VulkanPanel_render → element tree via vtable (saved, not yet rendered)
//       end_frame → vkEndCommandBuffer

//   RENDERER_BACKEND unset (default):

//   3. Frame counter survives the auto-generated frame loop (world state).
//   4. This file is DESIGNED to work with the Vulkan ABI library.
//      Set RENDERER_BACKEND=vulkan and the KainComponentSurface registry
//      routes "native_ui" through the libkain-vulkan-abi.so vtable.
//
// ARCHITECTURE (what happens at runtime):
//   RENDERER_BACKEND=vulkan:
//     vulkan_available() → kain_vulkan_runtime_capability() → 1
//     The 18-slot vtable calls route through the GPU backend.

// actor.kn — Audio Engine & Plugin Actors (std::audio Phase 2)
//
// Layer: L7 (actor — message-oriented stateful concurrency)
//
// Actors are Kain's mechanism for concurrent stateful entities.
// Each actor has:
//   - private `state` fields
//   - one or more `on MessageName(args):` handlers
//   - a `P` (port) type for reply destinations
//
// Communication is by typed messages:
//   spawn ActorName()  -> actor_id
//   send  actor_id.MessageName(args...)
//   ask   actor_id.MessageName(args...)  -> reply  (request/reply)
//
// The actors in this module are the runtime side of the std::audio
// stack: AudioEngine owns the audio device + mixer; PluginHost
// sandboxes third-party plugins; MidiRouter routes MIDI events to
// the right instrument; SessionManager owns project state.
//
// The reply port (`P`) in Kain accepts a synthetic `Reply` message
// whose payload is the typed return. Each handler in this file
// uses `send reply_to.Reply(...)` with the relevant fields.
//
// Actual native plugin loading (VST3 / AU / CLAP) is FFI-dependent
// and lands in the runtime lane. The actors here expose the full
// typed message surface; the FFI is the implementation detail.

// AudioBuffer is the fundamental unit of audio data. It owns a contiguous

// is a non-owning slice into an AudioBuffer. AudioRingBuffer is a lock-free
// SPSC circular buffer for streaming audio between threads.
//
// All public structs in this file are the CANONICAL definitions. DELTA's
// device.kn mirrors AudioView LOCALLY (with a comment that says "replace with
// use std::audio::buffer when CHARLIE ships") so it typechecks without this
// module. The field names match DELTA's local copy exactly so the swap is
// drop-in: remove the local struct, add `use std::audio::buffer` at the top,
// recompile.
//
// Real-time safety: buffer constructors and accessors are `with Unsafe` only
// where they touch raw pointer offsets. Pure read-only accessors are
// `with Pure`. The audio thread (pulse budget) may NOT call constructors.

// orchestrate.kn — Audio Signal Graph (std::audio Phase 1)
//
// Layer: L4 (orchestrate — typed multi-runtime stage graph)
//
// `orchestrate` is Kain's killer feature for DAWs. It defines a typed
// signal graph where each stage knows its inputs, outputs, residency
// (host/device/shared), and dependencies. The compiler can schedule
// stages across runtimes (CPU, GPU, converge lanes), optimize data
// transfers, and verify the graph is acyclic.
//
// The AudioGraph is the heart of the mixer: source -> gain -> effect
// chain -> master -> meter + sink. Each stage is declared with its
// runtime kind, residency, transfer policy, and (optionally) a
// capability guard, law gate, or fallback.
//
// All stage functions are `with Pure` so the compiler can reorder and
// parallelize them. The actual hot path runs inside a pulse
// budget(alloc=0, lock=0, io=0) callback (see pulse.kn), but the
// orchestrate declaration is the static plan the runtime uses.
//
// This file is self-contained: it does NOT import std::audio::buffer
// because the orchestrate stages operate on caller-provided audio
// samples via the runtime's audio callback scratch pool. The real
// AudioView / AudioBuffer types from std::audio::buffer are wired in
// by the device callback (device.kn) which already mirrors AudioView
// locally for the drop-in swap with buffer.kn.

// std::kain — Compiler service API
//
// This module exposes the Kain compiler as a service, allowing Kain-authored
// tooling (LSP, formatters, analyzers, linters) to use the compiler's parser,
// typechecker, indexing, and formatting capabilities through a clean Kain API.
//
// Architecture:
//   Kain types (this file) → builtin bridge (crates/service-bridge) → service-api (crates/service-api)
//
// The bridge layer is registered in the Kain runtime via register_stdlib_extension.
// Complex results are returned as Value::Struct from builtins and destructured here.

// NUMERICAL METHODS — Trait-based (zero function-pointer overhead)
// ============================================================================
//
// These functions use compile-time monomorphization via the `RealFunction`
// trait instead of fn-typed parameters, working around the LLVM indirect-call
// codegen gap (codegen Gap 4).
//
// Usage:
//   1. Define a struct holding any parameters your function needs
//   2. impl RealFunction for MyStruct (only `eval` is required)
//   3. Call newton_raphson<MyStruct>(my_instance, initial, tolerance, max_iters)
//
// Example:
//   struct MyQuadratic:
//       a: Float; b: Float; c: Float
//   impl RealFunction for MyQuadratic:
//       fn eval(self: Self, x: Float) -> Float:
//           return self.a * x * x + self.b * x + self.c
//   let f = MyQuadratic { a: 1.0, b: 0.0, c: -2.0 }
//   let root = newton_raphson<MyQuadratic>(f, 1.5, 0.0001, 100)

// ============================================================================
// stdlib_mks.kn
// ============================================================================
// ============================================================================
//  STD::MKS — First-Class Kain Stdlib Module for MarkScript Embedding
//
//  Makes it trivially easy for any Kain program to embed and drive the
//  Markscript VM. Markscript is a markdown-native intent engine — .md files
//  become executable configuration, data tables become typed matrices, and
//  blockquote intents ("> do something") dispatch to registered handlers.
//
//  ## Quick Start
//
//      use std::mks
//
//      // One-shot: load + execute a .md file
//      let vm = mks.run_file("config.md")
//
//      // One-shot: compile + execute a string
//      let vm = mks.run_string("# Hello\n\n> print world")
//
//      // Table access (tables parsed from markdown at compile time)
//      let count = mks.table_count(vm)
//      let host  = mks.get_string(vm, 0, 0, 0)   // table[0].row[0].col[0]
//      let port  = mks.get_int(vm, 0, 0, 1)      // table[0].row[0].col[1]
//
//  ## Manual VM Lifecycle
//
//      let vm = mks.make()                        // create fresh VM
//      let vm = mks.run_string(vm, "# MyConfig")  // execute on existing VM
//      if mks.ok(vm):                             // check success
//          let tables = mks.table_count(vm)
//      else:
//          println(mks.error(vm))
//
//  ## Custom Handler Registration
//
//      let vm = mks.make()
//      let vm = mks.bind(vm, "deploy app", 100)   // map phrase to handler_id
//      // Then intercept handler_id in your own dispatch loop
//
//  ## Ladder Rung
//  Layer 0 (fn) — this is a plain module exporting functions, structs, and
//  enums for embedding the Markscript VM. The VM itself uses value semantics
//  throughout (no ptr<T> parameters).
//
//  ## Relationship to the Markscript Blade
//  This stdlib module is self-contained. It includes the core Markscript VM,
//  parser, lexer, and bridge directly. For the full Markscript CLI tool
//  (mks.exe), see `blades/markscript/`.
//
//  ## Conventions
//  - All VM functions return a new VM (value semantics)
//  - Table indices are 0-based
//  - handler_id 0 means "no handler" / "not found"
//  - Error state is checked via `ok(vm)` or `error(vm)`

// ============================================================================
// ============================================================================
//  no_std.kn — Bare-Metal Gate for the Kain Standard Library
// ============================================================================
//  This module is the authoritative import surface for bare-metal Kain code.
//  When targeting --target baremetal (CompileTarget::BareMetal), import this
//  module to bring all bare-metal-safe stdlib modules into compilation scope:
//
//      use std::no_std
//
//  Then use individual CORE modules as normal:
//      use std::math
//      use std::hash
//      use std::collections
//
//  WHAT THIS MODULE DOES:
//    - Compiles all 24 CORE modules (pure Kain, no OS dependency)
//    - Compiles all 3 ALLOC modules (need kmalloc/kfree bridge)
//    - Compiles std::machine (CPU intrinsics + VM ops)
//    - Compiles 4 HYBRID modules (data types OK, I/O blocked)
//    - Documents which modules are BLOCKED on bare metal
//
//  WHAT IS BLOCKED (22 modules — requires hosted OS):
//    fs, net, os, os_path, process, platform, runtime,
//    python, cuda, gpu, graphics, graphics::shared,
//    actor, gen_server, input, ui, http, http2, mcp, tls,
//    thread, interop, wasm, js
//
//  See: docs/STDLIB_CATEGORY_MAP.md for the full categorization.
//  See: blades/os/stdlib/no_std_bridge.kn for KAINOS kernel bridge.
// ============================================================================

// ============================================================================
//  CORE — Pure Kain, works on bare metal (no kernel bridge needed)
// ============================================================================
//  24 modules. Pure computation, CPU intrinsics, or byte-buffer parsing.
//  Zero OS dependency. Safe to use on bare metal.

use std::math          // 250 symbols — vectors, matrices, quaternions, noise, intersections, colors
use std::hash          //  47 symbols — Wang hash, FNV-1a, CRC32, Fingerprint32
// NOTE: std::bits is NOT imported here because it defines rotl32/rotr32 which
// collide with std::hash's rotl32/rotr32 (stdlib collision — known issue).
// std::hash provides the rotation functions; import std::bits separately
// if you need popcount32, clz32, ctz32, bswap32, u8/u16/u32, i8/i16/i32,
// wrapping_add/sub/mul_u32.
// use std::bits          //  17 symbols — popcount, clz, ctz, bswap, rotl, rotr, wrapping arithmetic
use std::ascii         //  53 symbols — character classification, case conversion
use std::text          //  59 symbols — TextSlice, StringView, trim, split, join, escape

use std::target        //   6 symbols — Arch, OS, Env, Target enums, target_current()
use std::memory        //  19 symbols — volatile load/store, fences (lfence/sfence/mfence), prefetch
use std::atomic        //  44 symbols — atomic load/store/add/sub/cas/exchange with ordering
use std::bytes         //  33 symbols — ByteSlice, BytesBuilder, hex encode/decode
use std::crypto        //   9 symbols — SHA-256, SHA-512 hash primitives (excludes entropy)
use std::json          // 133 symbols — JSON parser/serializer
use std::semver        //  28 symbols — semantic version parser, compare, satisfies
use std::uri           //  10 symbols — URI parser (scheme, authority, path, query, fragment)
use std::tar           //   9 symbols — tar format parser

// ============================================================================
//  ALLOC — CORE modules that need a kernel heap (kmalloc/kfree bridge)
// ============================================================================
//  3 modules. These dynamically allocate memory. On bare metal, provide a
//  kernel allocator bridge via @link_name("KAIN_alloc").
//  See blades/os/stdlib/no_std_bridge.kn for KAINOS kernel backing.

use std::alloc         //  33 symbols — BumpAllocator, ArenaAllocator, PoolAllocator, AllocatorVTable
use std::collections   // 110 symbols — ArrayList, HashMap, SlotMap, PriorityQueue, StringIntMap, etc.
use std::io            //  29 symbols — RingBuffer, StringBuilder, BufferedReader, BufferedWriter

// ============================================================================
//  MACHINE — CPU intrinsics + VM operations
// ============================================================================
//  38 symbols. On bare metal:
//    SAFE (CPU intrinsics): pause, rdtsc, fences (load_fence/store_fence/full_fence),

//      cpu_logical_count, cpu_core_count, cpu_package_count,

//      vm_lock, vm_unlock, vm_map, vm_unmap, vm_map_huge,
//      vm_protect_* (none/read/read_write/execute_read/execute_read_write),
//      numa_node_count, numa_current_node, numa_bind_current_thread,
//      set_current_thread_affinity
//
//  VM ops will linker-error on bare metal without a kernel VMM bridge.
//  Use kainos::mm::virtual for kernel-backed VM operations.

use std::machine       //  38 symbols — CPU intrinsics + VM operations

// ============================================================================
//  HYBRID — Data types OK, I/O operations require kernel bridge
// ============================================================================
//  4 modules. Data types work on bare metal. I/O functions need kernel bridge.
//
//  std::time: Duration, Instant, Deadline, Ticker, DateTime types OK.
//    now_millis(), instant_now(), sleep_millis() → need HPET/APIC timer bridge.
//  std::random: Xoshiro128, ShatteredRngBuffer PRNG core OK.
//    random_ambient_* → need RDRAND or HPET jitter entropy.
//  std::sync: McsMutex (spinlock), TeleportChannel OK.
//    Once, WaitGroup, RwLock, Semaphore, CondVar → need OS parking.
//  std::intent: Pure wrappers (patch_status, law_status, converge_choose) OK.
//    native_* queries → need C runtime ABI (stub to 0 on bare metal).

use std::time          //  33 symbols — Duration, Instant, Deadline, Ticker, DateTime
use std::random        //  21 symbols — Xoshiro128, ShatteredRngBuffer, ambient entropy
use std::sync          //  62 symbols — MCS mutex, TeleportChannel, Once, WaitGroup, etc.

//                          std::os  —  The Mothership OS Module
// ============================================================================
//  
//  Uses the 'import os' mental model: one module, everything the OS gives you.
//
//  Architecture:
//    Layer 0 ─ raw @extern ABIs (fs, process, machine, platform, runtime, time)
//    Layer 1 ─ this module: Python-like unified facade
//    Layer 2 ─ std::os::path (os_path.kn) for path manipulation
//
//  Usage:
//    use std::os
//    let cwd = os_getcwd()
//    let files = os_listdir(".")
//    let home = os_getenv("HOME")
//    os_makedirs("a/b/c")
//
//  Zig inspiration per X:\reference\zigos:
//    - Platform-specific raw bindings → os.linux.zig / os.windows.zig pattern
//    - Sub-modules for syscall/DLL imports → kernel32.zig, ntdll.zig
//    - Cross-platform posix layer atop raw os → our wrappers here
//    - Higher stdlib (fs, process, net) consume os as substrate

//                    std::python::venv  —  Python Virtual Environment Management
// ============================================================================
//
//  Provides idempotent venv creation, package installation, and activation.
//  Interlocks with the C runtime (python_runtime.c) via the KAIN_PYTHON_VENV
//  environment variable: when set, the runtime calls Py_SetPythonHome() with
//  the venv path BEFORE Py_Initialize(), causing CPython to use the venv's
//  Lib/site-packages.
//
//  Usage:
//    use std::python::venv
//    let env = venv_ensure("./.venv", ["numpy>=1.24", "torch>=2.0"])
//    import numpy as np   // uses the venv's numpy
//
//  Architecture:
//    Layer 0 ─ @extern ABIs (fs, os, process) for I/O and shell calls
//    Layer 1 ─ this module: Python venv lifecycle
//    Layer 2 ─ user Kain code: import numpy as np (reads KAIN_PYTHON_VENV)
//
//  Env var priority (set by this module, read by the C runtime):
//    KAIN_PYTHON_VENV → path to .venv root → Py_SetPythonHome before init

// std::vulkan — Kain bridge to the Vulkan ABI library (libkain-vulkan-abi.so/.dll)
//
// This module maps Kain function calls to the C ABI symbols exported by the
// Vulkan ABI library (runtime/native/extras/vulkan-abi/). The library is
// dlopen'd by the vulkan_surface_shim when RENDERER_BACKEND=vulkan is set.
//
// Architecture:
//   Kain source → std::vulkan → @extern → libkain-vulkan-abi.so → vk* calls
//
// The 18-slot KainComponentSurface vtable handles window creation, frame
// lifecycle, and presentation. This module handles the GPU-specific operations:
// shader loading, uniform updates, and pipeline management.
//
// USE THIS WHEN:
//   - You have a shader (fragment/compute) compiled to SPIR-V hex
//   - You need per-frame uniform updates (time, resolution, mouse, custom)
//   - You're writing a Kain program that targets RENDERER_BACKEND=vulkan
//
// DO NOT USE THIS FOR:
//   - Window creation — the KainComponentSurface vtable handles that
//   - Component UI rendering — use world + surface native_ui => Component
//   - General GPU compute — use std::cuda or std::graphics
