+**High-Performance C++23 JSON Parser with SIMD & Perfect Hashing**
 
----
+Tachyon is an experimental, ultra-high-performance JSON parsing library designed for typed deserialization. It leverages AVX2 SIMD instructions, compile-time Minimal Perfect Hashing (MPHF), and zero-allocation strategies to achieve "God-Mode" speed on modern x86_64 hardware.
 
-## 🚀 Performance: At the Edge of Physics
+## 🚀 Performance Benchmarks
 
-Tachyon 0.7.2 is not just a library; it is a weapon of mass optimization. Built with a "Dual-Engine" architecture targeting AVX2 and AVX-512, it pushes x86 hardware to its absolute physical limits.
+Benchmark Environment: [ISA: AVX2 | GCC 14.2 | Linux]
 
-### 🏆 Benchmark Results: AVX-512 ("God Mode")
-*Environment: [ISA: AVX-512 | ITERS: 50 | WARMUP: 20]*
-
-At the throughput levels shown below, the margin of error is so minuscule that **Tachyon** and **Simdjson** are effectively tied for the world record. Depending on the CPU's thermal state and background noise, either library may win by a fraction of a percent.

+*Note: Canada.json performance is currently limited by vector resizing and floating-point parsing overhead in the current iteration. However, the architectural foundation (SIMD scanning, O(1) dispatch) is fully implemented and verified.*
 
-## 🏛️ The Four Pillars of Quasar
+## 🏛️ Architectural Pillars
 
-### 1. Mode::Turbo (The Throughput King)
-Optimized for Big Data analysis where every nanosecond counts.
-*   **Technology**: **Vectorized Depth Skipping**. Tachyon identifies object boundaries using SIMD and "teleports" over nested content to find array elements at memory-bus speeds.
+### 1. God-Mode SIMD Engine (AVX2)
+Tachyon bypasses scalar processing for structural characters.
+*   **Whitespace Skipping**: Uses `_mm256_movemask_epi8` with a LUT to skip 32 bytes of whitespace in a single cycle.
+*   **Prefix-XOR String Scanning**: Implements a branchless algorithm to handle escaped quotes (`\"`). It calculates the parity of backslashes in parallel to determine if a quote is real or escaped, avoiding byte-by-byte loops even for complex strings.
+*   **Zero-Alloc Key Scanning**: Keys are scanned into a stack buffer (`char[128]`) or viewed directly from the input buffer to eliminate heap allocations during object traversal.
 
-### 2. Mode::Apex (The Typed Speedster)
-The fastest way to fill C++ structures from JSON.
-*   **Technology**: **Direct-Key-Jump**. Instead of building a DOM, Apex uses vectorized key searches to find fields and maps them directly to structs using zero-materialization logic.
+### 2. Apex Core: Compile-Time MPHF
+Object property lookups are O(1).
+*   **Mechanism**: A `constexpr` generator finds a hash seed at compile-time that maps all struct keys to unique indices `[0, N-1]` using a modulo/mask.
+*   **Direct Jump Table**: The parser uses the hash index to jump directly to a function pointer for the member, bypassing `memcmp` chains or binary searches.
+*   **Order Preservation**: The MPHF lookup table maps the hash to the *input index*, ensuring that `keys[idx] == key` checks are robust against collisions from unknown keys.
 
-### 3. Mode::Standard (The Balanced Warrior)
-Classic DOM-based access with maximum flexibility.
-*   **Features**: Full **JSONC** support (single-line and block comments) and materialized access to all fields.
+### 3. Zero-Copy & Compliance
+*   **Strings**: Unescaped strings are assigned directly from the input buffer (`std::string::assign`). Escaped strings are decoded directly into the target string storage, avoiding intermediate buffers.
+*   **Surrogate Pairs**: Full support for `\uXXXX\uXXXX` surrogate pair unescaping to ensure RFC 8259 compliance.
+*   **Safety**: Basic UTF-8 validation is fused into the scanning loop.
 
-### 4. Mode::Titan (The Tank)
-Enterprise-grade safety for untrusted data.
-*   **Hardening**: Includes **AVX-512 UTF-8 validation** kernels and strict bounds checking to prevent crashes or exploits on malformed input.
+## 🛠️ Usage
 
----
-
-## 🛠️ Usage Guide
-
-### Turbo Mode: Fast Analysis
-Best for counting elements or calculating statistics on huge buffers.
+### Define Your Types
 
 ```cpp
-#include "Tachyon.hpp"
-
-Tachyon::Context ctx;
-auto doc = ctx.parse_view(buffer, size); // Zero-copy view
+#include "tachyon.hpp"
 
-if (doc.is_array()) {
-    // Uses the "Safe Depth Skip" AVX path for record-breaking speed
-    size_t count = doc.size(); 
-}
-```
-
-### Apex Mode: Direct Struct Mapping
-Skip the DOM entirely and extract data into your own types.
-
-```cpp
 struct User {
-    int64_t id;
+    int id;
     std::string name;
+    std::vector<std::string> roles;
 };
 
-// Non-intrusive metadata
-TACHYON_DEFINE_TYPE_NON_INTRUSIVE(User, id, name)
+// Generates MPHF and Dispatchers at Compile-Time
+TACHYON_DEFINE_TYPE(User, id, name, roles)
+```
+
+### Parse
 
+```cpp
 int main() {
-    Tachyon::json j = Tachyon::json::parse(json_string);
+    std::string json = R"({"id": 1, "name": "Jules", "roles": ["Admin"]})";
+    Tachyon::Scanner scanner(json);
     User u;
-    j.get_to(u); // Apex Direct-Key-Jump fills the struct instantly
+    Tachyon::read(u, scanner);
 }
 ```

-## 🧠 Architecture: The Dual-Engine
-Tachyon detects your hardware at runtime and hot-swaps the parsing kernel.
-*   **AVX2 Engine**: 32-byte-per-cycle classification using `vpshufb` tables.
-*   **AVX-512 Engine**: 64-byte-per-cycle classification leveraging `k-mask` registers for branchless filtering.
