From ebba63d71f677a8457d8e786b5d04c6b59d8134d Mon Sep 17 00:00:00 2001 From: jochen Date: Sun, 11 Oct 2026 12:06:18 +0200 Subject: [PATCH 1/2] mesh-knowledge: review every proposal in a judgement of its own, and serve no review verb (hq issue 425, ADR 0290 as updated) The mesh proves which machine called, not which agent on it (hq issue 365), so a review verb could not tell a reviewer from the author. Each version proposed is now judged by claude-code.claude_code_judge in a separate call that sees only the record, the records it links and the rules: approve accepts (or asks the operator for a needs-operator record), changes keeps it proposed with the findings for its author, and a judgement that cannot be had or read leaves it proposed, says so, and never counts as approval. --- modules/mesh-knowledge/README.md | 46 ++- .../cmd/mesh-knowledge/answers.go | 25 ++ .../cmd/mesh-knowledge/bus_test.go | 10 +- .../mesh-knowledge/cmd/mesh-knowledge/kb.go | 123 ++----- .../cmd/mesh-knowledge/kit_test.go | 54 +++- .../mesh-knowledge/cmd/mesh-knowledge/main.go | 62 ++-- .../cmd/mesh-knowledge/manifest_test.go | 2 +- .../cmd/mesh-knowledge/operator.go | 44 ++- .../cmd/mesh-knowledge/record.go | 24 +- .../cmd/mesh-knowledge/review.go | 302 +++++++++++++++++ .../cmd/mesh-knowledge/review_test.go | 303 +++++++++++++----- .../cmd/mesh-knowledge/wholeset_test.go | 13 +- .../cmd/mesh-knowledge/writers_test.go | 48 +-- modules/mesh-knowledge/module.json | 2 - 14 files changed, 743 insertions(+), 315 deletions(-) create mode 100644 modules/mesh-knowledge/cmd/mesh-knowledge/review.go diff --git a/modules/mesh-knowledge/README.md b/modules/mesh-knowledge/README.md index e1f0a255..d5f82b1f 100644 --- a/modules/mesh-knowledge/README.md +++ b/modules/mesh-knowledge/README.md @@ -8,8 +8,8 @@ it makes, with its own status and source.
