OathConnect 0.3.0-alpha.2 — Sepolia proof and relay quota repair

Development preview: safer provider error reporting, corrected relay quota accounting and the first confirmed restricted EVM transfer through the local relay.

• HTTP errors expose only the RPC method and numeric status; unread error bodies are cancelled. Uncertain submissions are never retried automatically.
• Capacity-rejected allocations now consume the project's global request budget. A reproduced case with 100 accepted allocations and 500 rejected ones now rejects request 601. Over-budget traffic still requires quota lookups; distributed load/cost qualification remains open.
• A fresh disposable account completed a one-wei Sepolia transfer in block 12028472 using the reusable EVM adapter, one approval/signature/submission and PublicNode. Two providers agree on the canonical receipt; the expected transfer log, gas and balance change were checked. See the dated evidence for finality scope. Earlier failed and uncertain attempts remain archived, with no resubmission.

Validation: 48 TypeScript tests, 16 Swift SDK host tests, one Swift fixture host test, three JavaScript fixture tests, dependency audits and Cloudflare dry run. Native source is unchanged from the successful generic iOS build at the previous milestone. No simulator or physical-device test. Separate internal reviews found no additional actionable issues in their stated scopes; these are not an independent external audit.

Four exact GitHub CI package archives, SHA256SUMS and RELEASE-EVIDENCE.json are attached. Install all four archives together; this is not an npm registry publication. Deployed-relay EVM tests, ERC-20 qualification, other networks, THORChain swaps and production approval remain open. Oath Wallet is untouched.
