From bfa8f397790c66f2c1a10d3f426a6cab5d6d0d35 Mon Sep 17 00:00:00 2001 From: opencode Date: Tue, 16 Jun 2026 21:57:12 +0200 Subject: [PATCH] feat(verifier): polyglot check detection (issue #154) What ships: - cmd/sin-code/internal/orchestrator/detect.go: new file - 4 ecosystem detectors: go.mod, package.json, Cargo.toml, pyproject.toml - DetectChecks(workspace) walks 1 level deep so monorepos with nested ecosystems are covered - matched map dedupes by name+marker - Falls back to DefaultGoChecks for empty workspaces - 8 race-clean unit tests in detect_test.go Acceptance criteria (from #154): - [x] DetectChecks picks build/test/lint based on marker files. - [x] Multiple ecosystems in a monorepo are additively combined. - [x] Fallback to DefaultGoChecks for Go-only repos with no markers preserves current behavior. - [x] No new deps (stdlib only). Hard mandates honored: - M2: stdlib only. - M3: detect is a one-shot helper; the verify-gate semantics are unchanged (operator can still override checks per-task). - M7: 8/8 tests pass under go test -race -count=1.
