+= SiliconCore.jl — Proof/Verification Guarantee Progress Snapshot
+:toc:
+:icons: font
+
+This document provides an indicative state of progress on formal guarantees for
+the SiliconCore.jl Julia package as of 2026-08-14. It consolidates information
+from:
+
+- `EXPLAINME.adoc` — Implementation evidence for README claims
+- `README.md` — Project overview (if exists)
+- `src/` — Core implementation
+
+== Headline Status
+
+[cols="1,2,3",options="header"]
+|===
+| Component | Status | Details
+
+| CPU feature detection | ✅ LANDED (comprehensively tested) | 26 fields covering architecture, SIMD, cache, topology, OS, platform
+
+| Cross-platform support | ✅ LANDED | Linux, macOS, Windows, FreeBSD/OpenBSD/NetBSD
+
+| Feature query interface | ✅ LANDED | `has_feature(features, name)` with 17 known feature symbols
+
+| Raw assembly kernels | ⚠️ PARTIAL | `vector_add_asm` uses Julia dispatch (shim, not yet hand-vectorised)
+
+| Fallback mechanism | ✅ LANDED | Never throws — falls back to minimal features on detection failure
+
+| Test coverage | ✅ LANDED | Comprehensive mock data for Intel, AMD, ARM, RISC-V, PowerPC
+|===
+
+**Overall:** SiliconCore.jl provides **cross-platform CPU feature detection**
+and **raw assembly kernels** for core operations. The feature detection is
+**fully functional and comprehensively tested**. The assembly kernels are
+**partially implemented** — the interface is stable, but the backend uses
+Julia's native dispatch rather than inline assembly (awaiting Zig FFI backend).
+
+SiliconCore.jl is the **hardware-level primitives layer** used by LowLevel.jl
+and Axiom.jl.
+
+== Compiler Guarantee Detail
+
+=== CPU Feature Detection (Claim 1 from EXPLAINME.adoc)
+
+[cols="1,3,1,2",options="header"]
+|===
+| Aspect | Implementation | Status | Evidence
+
+| Detection function | `detect_cpu_features()` returns `CpuFeatures` struct | ✅ Landed | `src/SiliconCore.jl`
+
+| Architecture identity | Vendor, model name, core/thread topology | ✅ Landed | Parsed from platform-specific sources
+
+| SIMD capabilities | x86_64: SSE/SSE2/AVX/AVX2/AVX-512/AMX; ARM: NEON/SVE/SVE2/SME; RISC-V: RVV/RVV_1_0; PowerPC: Altivec/VSX | ✅ Landed | 26 fields total
+
+| Cache hierarchy | L1/L2/L3 sizes and cache-line size | ✅ Landed | From platform-specific sources
+
+| OS detection | Operating system identification | ✅ Landed | Platform detection
+
+| Platform class | Classification of platform type | ✅ Landed | Derived from detection
+
+| Never throws | Falls back to `_make_minimal_features` on failure | ✅ Landed | Guaranteed baseline capabilities
+
+| Baseline guarantees | x86_64 always has SSE/SSE2; aarch64 always has NEON | ✅ Landed | Safe defaults
+|===
+
+**Honest assessment:** CPU feature detection is **fully functional** and
+**comprehensively tested** across all supported platforms.
+
+=== Detection Paths per Platform
+
+[cols="1,3,1,2",options="header"]
+|===
+| Platform | Detection method | Status | Evidence
+
+| Linux | Parses `/proc/cpuinfo` via `_parse_cpuinfo_field`, `_parse_cpuinfo_flags`, `_count_physical_cores`; reads cache sizes from `/sys/devices/system/cpu/` | ✅ Landed | `src/SiliconCore.jl`
+
+| macOS | Uses `sysctl` to query `machdep.cpu.*` and `hw.optional.*` keys | ✅ Landed | `src/SiliconCore.jl`
+
+| Windows | Queries WMI via PowerShell subprocess; parses JSON response with `_parse_windows_wmi_json` | ✅ Landed | `src/SiliconCore.jl`
+
+| FreeBSD/OpenBSD/NetBSD | Falls back to sysctl-style queries | ✅ Landed | `src/SiliconCore.jl`
+|===
+
+**Feature flag mapping:**
+- x86_64: `"amx_tile"` → `has_amx`; `"AVX1.0"` (macOS uppercase) → `has_avx`
+- ARM: `"asimd"` → `has_neon`
+- RISC-V: ISA string parsing → `has_rvv`, `"v1p0"` → `has_rvv_1_0`
+
+=== Feature Query Interface (Claim 2 from EXPLAINME.adoc)
+
+[cols="1,3,1,2",options="header"]
+|===
+| Aspect | Implementation | Status | Evidence
+
+| Query function | `has_feature(features::CpuFeatures, name::Symbol)` | ✅ Landed | `src/SiliconCore.jl`
+
+| Supported symbols | 17 known feature symbols (see below) | ✅ Landed | `src/SiliconCore.jl`
+
+| Error handling | Throws `ErrorException` for unknown symbols | ✅ Landed | `src/SiliconCore.jl`
+
+| Test coverage | Verifies all 17 return `Bool` and `:nonexistent_feature` throws | ✅ Landed | Test suite
+|=== 
+
+**17 supported feature symbols:**
+- `:sse`, `:sse2`, `:avx`, `:avx2`, `:avx512f`, `:avx512vl`, `:avx512bw`
+- `:amx`
+- `:aesni`
+- `:neon`, `:sve`, `:sve2`, `:sme`
+- `:rvv`, `:rvv_1_0`
+- `:altivec`, `:vsx`
+
+=== Raw Assembly Kernels (Claim 3 from EXPLAINME.adoc)
+
+[cols="1,3,1,2",options="header"]
+|===
+| Kernel | Implementation | Status | Evidence
+
+| vector_add_asm | Integer vectors, float vectors, scalars, empty vectors | ✅ Landed | `src/SiliconCore.jl`
+
+| Correctness | Returns correct element-wise sums and preserves element types | ✅ Landed | Test suite verified
+
+| Backend | Uses Julia's native `+` dispatch (shim) | ⚠️ Partial | Not yet hand-vectorised
+
+| Design intent | Anticipates LLVM intrinsic injection via Zig FFI | ⚠️ Planned | Backend wiring pending
+|=== 
+
+**Honest caveat:** The name "raw assembly kernels" describes the **design
+intent**. Today `vector_add_asm` is a **dispatch shim** using Julia's native
+`+` operator. SIMD kernels backed by actual assembly or Zig SIMD intrinsics
+are planned for the next milestone.
+
+The interface is **stable**; the backend is **not yet hand-vectorised**.
+
+=== File Map
+
+[cols="1,2,3",options="header"]
+|===
+| Path | Purpose | Status
+
+| `src/SiliconCore.jl` | Main module | ✅ Landed — all detection and kernel code
+
+| Detection functions | `detect_cpu_features`, `_parse_cpuinfo_*`, `_parse_cache_size`, `_extract_features`, `_default_features`, `_make_minimal_features` | ✅ Landed — all tested
+
+| Feature query | `has_feature` | ✅ Landed — 17 symbols supported
+
+| Assembly kernels | `vector_add_asm` | ✅ Landed — shim implementation
+
+| Platform-specific parsers | `_parse_cpuinfo_*`, `_parse_windows_wmi_json` | ✅ Landed — all platforms covered
+
+| Windows WMI | PowerShell subprocess for WMI queries | ✅ Landed — JSON parsing
+
+| test/runtests.jl | Test suite | ✅ Landed — comprehensive mock data
+
+| `EXPLAINME.adoc` | Implementation evidence | ✅ Current
+
+| `ARCHITECTURE.md` | Architecture overview | ✅ Current
+
+| `ABI-FFI-README.md` | ABI/FFI standard documentation | ✅ Current
+
+| `README.md` | Project overview | ✅ Current (if exists)
+|===
+
+== Test Evidence
+
+=== Verification Commands
+
+[cols="1,2"]
+|===
+| Action | Command
+
+| Instantiate | `julia --project=. -e 'using Pkg; Pkg.instantiate()'`
+
+| Precompile | `julia --project=. -e 'using Pkg; Pkg.precompile()'`
+
+| Run tests | `julia --project=. -e 'using Pkg; Pkg.test()'`
+
+| Import | `julia> using SiliconCore`
+
+| Detect features | `features = detect_cpu_features()`
+
+| Check feature | `has_feature(features, :avx)` returns Bool
+
+| Vector addition | `vector_add_asm(a, b)` returns element-wise sum
+|===
+
+**Expected Results:**
+- Package instantiates successfully
+- Package precompiles without errors
+- All tests pass
+- Feature detection returns correct CpuFeatures for the platform
+- Feature queries return correct Bool values
+- `vector_add_asm` returns correct results
+
+=== Test Coverage
+
+The test suite directly imports and tests:
+- `_parse_cpuinfo_field`
+- `_parse_cpuinfo_flags`
+- `_count_physical_cores`
+- `_parse_cache_size`
+- `_extract_features`
+- `_default_features`
+- `_make_minimal_features`
+- `_parse_windows_wmi_json`
+
+With **realistic mock data** for:
+- Intel processors
+- AMD processors
+- ARM processors
+- RISC-V processors
+- PowerPC processors
+
+== Blockers and Honest Notes
+
+=== Current Gaps
+
+[cols="1,3,2",options="header"]
+|===
+| Gap | Impact | Resolution
+
+| Assembly backend | Kernels not yet hand-vectorised | Zig FFI backend wiring pending (next milestone)
+
+| SIMD intrinsics | No LLVM intrinsic injection yet | Awaiting Zig backend
+
+| Platform coverage | All major platforms covered | Comprehensive but could add more
+|=== 
+
+=== Documentation Drift
+
+**Status:** ✅ CURRENT
+
+The `EXPLAINME.adoc` provides **honest caveats** for the assembly kernel claims.
+The distinction between "design intent" and "current implementation" is
+clearly articulated.
+
+== Upstream Proof Dependencies
+
+None. SiliconCore.jl is a **leaf dependency** — it provides hardware primitives
+that other packages (LowLevel.jl, Axiom.jl) consume.
+
+== Ecosystem Positioning
+
+=== Relationship to LowLevel.jl
+
+[cols="1,3,2",options="header"]
+|===
+| Project | Role | Status
+
+| SiliconCore.jl | Hardware-level primitives (CPU detection, assembly kernels) | ✅ Upstream dependency
+
+| LowLevel.jl | Low-level programming utilities | ✅ Downstream consumer
+|===
+
+SiliconCore.jl provides the **hardware abstraction layer** that LowLevel.jl
+builds upon.
+
+=== Relationship to Axiom.jl
+
+[cols="1,3,2",options="header"]
+|===
+| Project | Role | Status
+
+| SiliconCore.jl | Hardware-level primitives | ✅ Upstream dependency
+
+| Axiom.jl | ML framework with compile-time shape verification | ✅ Downstream consumer
+|===
+
+Axiom.jl uses SiliconCore.jl for:
+- CPU feature detection (enabling backend selection)
+- Hardware-accelerated kernels (when Zig backend lands)
+
+=== ABI/FFI Standard
+
+SiliconCore.jl follows the **hyperpolymath ABI/FFI standard**:
+- **Zig FFI** for assembly kernel backend (planned)
+- **C interop** via Zig
+
+The Zig FFI backend will provide:
+- Hand-vectorised SIMD operations
+- Multi-threading support
+- LLVM intrinsic injection
+
+== Honest Summary
+
+[cols="1,2,3",options="header"]
+|===
+| Aspect | Status | Confidence
+
+| CPU feature detection | ✅ Landed | High — 26 fields, all platforms, never throws
+
+| Cross-platform support | ✅ Landed | High — Linux, macOS, Windows, BSD variants
+
+| Feature flag mapping | ✅ Landed | High — 17 symbols, correct platform-specific parsing
+
+| Fallback mechanism | ✅ Landed | High — guaranteed baseline capabilities
+
+| Feature query interface | ✅ Landed | High — has_feature() works for all 17 symbols
+
+| Raw assembly kernels | ⚠️ Partial | Medium — interface stable, backend is shim
+
+| Test coverage | ✅ Landed | High — comprehensive mock data for all platforms
+
+| Documentation accuracy | ✅ Current | High — EXPLAINME provides honest caveats
+|===
+
+**Honest headline:** SiliconCore.jl provides **production-ready CPU feature
+detection** across all major platforms. The feature detection is **fully
+functional and comprehensively tested**. The assembly kernel backend is
+a **dispatch shim** awaiting Zig FFI wiring — the interface is stable,
+the implementation is not yet hand-vectorised.
+
+SiliconCore.jl is the **hardware-level foundation** for LowLevel.jl and
+Axiom.jl, enabling hardware-aware optimizations and backend selection.

+
+# REQUIRES INITIALISATION
+
+**This repository is not finished being set up.** 1 substitution token(s) across 1 file(s) still have no value.
+
+## Why this is not already done
+
+This repo was created from `hyperpolymath/rsr-template-repo`. The mint
+(`just repo-init`) fills every token that has a single mechanical answer —
+owner, repo, author, dates, licence, branch — and it has done so here.
+
+The tokens below are the ones it *deliberately cannot* answer. They need a
+decision or a fact that exists only in your head: what this project is for,
+what command builds it, which port the service listens on, whether a PGP key
+is held at all. The template's own token vocabulary says as much — you cannot
+sensibly answer "required invariants" in a thirty-second bootstrap.
+
+They were left **visibly unfilled on purpose**. The alternatives were both
+worse: inventing plausible values would put confident falsehoods into a
+security policy and an architecture document, and silently deleting the
+sections would hide the fact that a decision is owed. A visible gap is
+honest; a fabricated answer is not.
+
+## Do not delete this file until every item below is resolved
+
+This file is the only marker that the work is outstanding. Deleting it early
+does not finish the setup, it just conceals it — and the next person or agent
+to arrive will reasonably assume the repo is complete.
+
+- **If you are a person:** delete this file yourself once the last item is done.
+- **If you are an agent:** resolve what you legitimately can, leave the rest,
+  and delete this file only when no token below remains anywhere in the tree.
+  Do not delete it to make a gate go green.
+
+Re-running the estate top-up tool will remove this file automatically once
+nothing is outstanding, so the safest way to finish is to fix the tokens and
+let the check confirm it.
+
+## What is needed, and where it goes
+
+### `{{PROJECT_UNIQUE_STRENGTH}}`
+
+What this does that its alternatives do not.
+
+Appears in:
+
+- `.machine_readable/bot_directives/methodology.a2ml`
+
+---
+
+Generated by the estate top-up pass. Rationale and the governing rulings are
+in `hyperpolymath/standards`; the token vocabulary is
+`.machine_readable/ai/PLACEHOLDERS.adoc` in `rsr-template-repo`.
