Technical Specification: Isomorphic Binding Architecture

#webdev #programming #ai #polyglot

Core Philosophy: "All Bindings Are Drivers" 

SQUARE (Perfect Binding):
┌────────────┐
│            │  All 4 sides equal
│   Binding  │  = Symmetric process
│            │  = Bidirectional FFI
└────────────┘

RECTANGLE (Driver):
┌──────────────────┐
│                  │  2 pairs of equal sides
│     Driver       │  = Asymmetric interface
│                  │  = Request/Response pairs
└──────────────────┘

Isomorphic Transform Rules

For your example {x: 20.5, y: 70}:

// Canonical Intermediate Representation (CIR)
typedef struct {
    enum { FLOAT64, INT64, STRING, NESTED } type;
    union {
        double f64;
        int64_t i64;
        char* str;
        void* nested;
    } value;
} CIR_Value;

typedef struct {
    char* key;
    CIR_Value value;
} CIR_Field;

typedef struct {
    CIR_Field* fields;
    size_t field_count;
} CIR_Object;

Language-Specific Mappings

Language Native Type CIR Transform Driver Format
Python {"x": 20.5, "y": 70} CIR_Object Binary protocol
Go struct{X float64; Y int} CIR_Object Binary protocol
COBOL 01 POINT. 05 X PIC 9(2)V9. 05 Y PIC 9(2). CIR_Object Binary protocol
Java class Point{Float x; Integer y;} CIR_Object Binary protocol

Zero-Trust Protocol

Each binding registers with cryptographically-seeded GUID:

typedef struct {
    uint8_t seed[32];  // Cryptographic seed
    uint64_t session;  // Session identifier
    uint32_t sequence; // Message sequence
    uint16_t checksum; // Data integrity
} PolyCall_Header;

Build Orchestration

The unified Makefile ensures all bindings compile to the same ABI:

POLYCALL_ABI = -fPIC -shared -Wl,-soname,lib$@.so.1
CANONICAL_IR = -DUSE_CANONICAL_IR=1

%.so: %.c
    $(CC) $(CFLAGS) $(POLYCALL_ABI) $(CANONICAL_IR) $< -o $@

State Machine Mapping

Every cross-language call follows this state progression:

  1. Parse → Language-specific AST
  2. Transform → Canonical IR (lossless)
  3. Validate → Type coercion matrix
  4. Marshal → Binary protocol
  5. Route → DRIVER daemon
  6. Unmarshal → Target language
  7. Execute → Native invocation
  8. Return → Reverse transform

This ensures the "square perfect" binding where input/output maintain structural equivalence across all supported languages.

The key insight: by treating all bindings as drivers with paired interfaces (rectangle), we achieve the perfect square of bidirectional communication without data loss.
