Function obfuscate_code 

pub fn obfuscate_code(base: &ErrorCode) -> ErrorCode

Apply obfuscation to an error code using current session salt.

Creates a new ErrorCode with:

• Same namespace (e.g., “CFG”)
• Same category (e.g., Configuration)
• Offset numeric code (e.g., 100 → 103)

The offset wraps within the namespace’s range to avoid collisions.

Example

use palisade_errors::{obfuscation, definitions};

// Base: E-CFG-100
obfuscation::init_session_salt(3);
let obfuscated = obfuscation::obfuscate_code(&definitions::CFG_PARSE_FAILED);
// Result: E-CFG-103

obfuscation::init_session_salt(7);
let obfuscated = obfuscation::obfuscate_code(&definitions::CFG_PARSE_FAILED);
// Result: E-CFG-107

Namespace Safety

The obfuscation ensures codes stay within their namespace:

• CFG (100-199): offsets wrap within 100-199
• IO (800-899): offsets wrap within 800-899
• etc.
