sologger-idl-decoder

Decodes what Anchor programs emit — Program data: events and custom program error codes — into structured form, driven purely by the program's IDL JSON.

• Supports both the legacy (pre-0.30) and the 0.30+ Anchor IDL spec, including the differing discriminator layouts (explicit discriminator arrays vs sha256("event:<Name>")[..8]).
• Parses the IDL with serde instead of depending on anchor-lang, keeping the dependency tree small and WASM-friendly.
• Enriches LogContext records from sologger-log-context in place: data_logs become decoded_events, and error_code resolves to error_name via the IDL's errors array.

let mut registry = IdlRegistry::new();
registry.insert_json("CPMMoo8L3F4NbTegBCKVNunggL7H1ZpdTHKxQB5qKP1C", idl_json)?;

// log_contexts from LogContext::parse_logs / the transformer crates
registry.enrich_all(&mut log_contexts);

Used by the sologger binary (via the idls map in sologger-config.json) and by sologger-log-transformer-wasm for the browser UI.
