Pre-build acceptance observation

• GREEN (prepassed): io-001-input-conformance (FEATURE-IO-001.md)

intent: The authoritative corpus cases covering input stream controls execute and pass. return code: 0 stdout: { "candidate": [ "/mnt/c/Users/barlo/projects/drydock/uat/jq/runs/20260822.044627/build/jq/jq" ], "corpus": "jq.test", "summary": { "pass": 1, "fail": 0, "error": 0, "skip": 0 }, "cases": [] }

• GREEN (prepassed): io-001-streams (FEATURE-IO-001.md)

intent: The selected corpus includes both single-next-input and remaining-input stream behavior. return code: 0 stdout: { "candidate": [ "/mnt/c/Users/barlo/projects/drydock/uat/jq/runs/20260822.044627/build/jq/jq" ], "corpus": "jq.test", "summary": { "pass": 1, "fail": 0, "error": 0, "skip": 0 }, "cases": [] }
