From 9f73708ea7e1e57dbea7691efcf36635cf2d0dc6 Mon Sep 17 00:00:00 2001 From: SIN CI Date: Tue, 16 Jun 2026 20:13:43 +0200 Subject: [PATCH] test(coverage): 100% for assets, apiweb, commands, dataset, dispatch, dox, eval, ghbridge, goalcontract, health, hooks, llm, logger - Adds package-level hooks where needed for error-path testing. - Extends tests to cover every statement in the 13 packages. All 13 packages verified at 100.0% statement coverage. --- cmd/sin-code/internal/apiweb/api.go | 32 +- cmd/sin-code/internal/apiweb/coverage_test.go | 373 +++++++++
