Greptile Summary

This PR adds the Yield+ infrastructure plumbing: a WsClient abstract base class with exponential-backoff reconnect and idle-disconnect logic, a wsApiUrl config entry, three new FunctionKey entries, K-line candle constants, time constants, Vault domain types, and the RelativePositionManager ABI. All findings are minor style/quality suggestions (P2) with no blocking issues.

Confidence Score: 5/5

Safe to merge — all findings are non-blocking P2 style suggestions.

No P0 or P1 issues found. The WebSocket implementation is logically sound (correct reconnect/idle-disconnect lifecycle, no timer leaks, rogue-reconnection guard). The two WsClient comments and the cent-type inconsistency in Vault types are quality improvements worth addressing but do not affect correctness or production reliability.

apps/evm/src/libs/webSocket/index.ts and apps/evm/src/types/index.ts have minor style findings worth a quick look.

Important Files Changed

Filename	Overview
apps/evm/src/libs/webSocket/index.ts	New WsClient abstract base with exponential-backoff reconnect and idle-disconnect logic; error handler discards error detail and openChannel may send duplicate subscribe messages.
apps/evm/src/types/index.ts	Adds Vault type hierarchy (BaseVault, VenusVault, PendleVault) and ApiOhlcInterval; cent-value types are inconsistent (number vs BigNumber) across the Vault interfaces.
apps/evm/src/config/index.ts	Adds wsApiUrl to Config interface, derived as wss://${apiHost}/ws — straightforward and consistent with existing config pattern.
apps/evm/src/constants/functionKey.ts	Adds three new FunctionKey entries (GET_RAW_YIELD_PLUS_POSITIONS, GET_TOKEN_PAIR_K_LINE_CANDLES, GET_FIXED_RATED_VAULTS) following existing naming conventions.
apps/evm/src/constants/klineCandles.ts	New file exporting INTERVAL (ApiOhlcInterval) and CHART_PERIOD for K-line chart configuration; naming and typing are consistent with project conventions.
apps/evm/src/setupTests.tsx	Adds wsApiUrl: 'fakeWsApiUrl' to the shared test config mock to satisfy the new Config shape; no issues.
apps/evm/src/config/apiUrls.ts	Unchanged API host mapping; WebSocket URL is derived in config/index.ts from the existing host.
apps/evm/src/constants/time.ts	Adds ONE_HOUR_MS and ONE_DAY_MS convenience constants; follows UPPER_SNAKE_CASE convention.
.claude/scripts/utils/image.ts	New utility that wraps macOS sips to downscale PNG images; correctly no-ops on non-macOS platforms.
.changeset/yield-plus-pr03-yieldplus-infra.md	Standard changeset entry for the Yield+ infra patch; no issues.
