From 00797241b89d694b0c6c7c6aa4bcc264b261959b Mon Sep 17 00:00:00 2001 From: Abhinavexist Date: Thu, 23 Jul 2026 03:04:56 +0530 Subject: [PATCH 1/2] test: production-harden the suite (error contract, tasks, guard, schema, coverage gate) Mirrors interfaze-python PR #18's test hardening: dedicated errors/schema/tasks/guard suites, a shared real-asset fixture map, deeper inputs/chat/stream coverage (from_path, data-URL edge cases, control headers, tool-call streaming, malformed side-channels), and a v8 coverage gate (100% lines/statements/functions, 94%+ branches) wired into CI. ---
