fix(API): treat CHIA_NETWORK as binary mainnet vs testnet in /diagnostics

TheLastCicada · TheLastCicada · commit 5275d276752f · 2026-05-12T14:40:53.000-07:00
CADT's CHIA_NETWORK config is a binary mainnet-vs-testnet flag, not an exact chia network name. Cross-referenced against every use in the codebase: - defaultConfig.js sets it to 'mainnet' - config-loader.js forces it to the literal string 'testnet' when USE_SIMULATOR=true, regardless of the actual underlying network - coin-management.js branches on '=== mainnet ? XCH : TXCH' - data-assertions.js accepts any chia network whose name contains CHIA_NETWORK as a substring The CI run on commit 286fcbb confirmed the previous strict-equality check gave the wrong answer in the real world: chia reported 'testneta', CADT config was 'testnet', diagnostics reported matches:false even though CADT itself treats them as a match. Normalize both sides to mainnet|testnet before comparing. This is both strictly more correct than the original substring rule (no testnet1/testnet10 false positive) and operationally aligned with how the rest of CADT interprets CHIA_NETWORK. The existing assertChiaNetworkMatchInConfiguration still uses the substring rule -- harmonising the assertion with this normalised comparison is a sensible follow-up but is left out of this PR to keep the scope tight.
