From f58840b8a6e62490bc22d476c00d356ada54c5ac Mon Sep 17 00:00:00 2001 From: jochen Date: Sat, 10 Oct 2026 17:11:54 +0200 Subject: [PATCH 1/2] mesh-issues: check every new issue for a duplicate; claude-code: one judgement with no tools (hq ADR 0278) The operator asked for duplicate issues to be consolidated as they are opened. The tracker consumes its own opened event and asks the agent on its node, through claude-code's new claude_code_judge, whether an older issue not resolved asks the same question; it closes only the newer issue of a certain duplicate, keeping its report on the older one, and fails loudly when it cannot judge. groom runs the same judgement over the backlog as a dry run, applied on confirm. --- modules/claude-code/README.md | 10 + modules/claude-code/cmd/claude-code/judge.go | 246 ++++++ .../claude-code/cmd/claude-code/judge_test.go | 168 ++++ modules/claude-code/cmd/claude-code/main.go | 1 + modules/claude-code/module.json | 3 +- modules/mesh-issues/README.md | 31 + modules/mesh-issues/cmd/mesh-issues/groom.go | 758 ++++++++++++++++++ .../mesh-issues/cmd/mesh-issues/groom_test.go | 443 ++++++++++ modules/mesh-issues/cmd/mesh-issues/main.go | 48 +- .../cmd/mesh-issues/manifest_test.go | 15 +- .../cmd/mesh-issues/memory_test.go | 2 +- .../mesh-issues/cmd/mesh-issues/tracker.go | 24 +- modules/mesh-issues/module.json | 17 +- 13 files changed, 1750 insertions(+), 16 deletions(-) create mode 100644 modules/claude-code/cmd/claude-code/judge.go create mode 100644 modules/claude-code/cmd/claude-code/judge_test.go create mode 100644 modules/mesh-issues/cmd/mesh-issues/groom.go create mode 100644 modules/mesh-issues/cmd/mesh-issues/groom_test.go diff --git a/modules/claude-code/README.md b/modules/claude-code/README.md index 65171d55..9ac99a29 100644 --- a/modules/claude-code/README.md +++ b/modules/claude-code/README.md @@ -192,6 +192,16 @@ what a session obeys as surely as placing one.

A judgement that fails — no answer, a late one, an answer outside the shape, an +issue not offered — leaves one note saying why, and the event is not taken: the bus offers it again, and after +its fifth delivery the controller raises `max-deliveries` on the module's consumer and keeps the event for a +person to deliver again. + +`groom` runs the same judgement over every issue not resolved and not yet checked, oldest first, against the +older ones not resolved and not found a duplicate in the same pass. It writes only the pass, in the state +`grooming` (the last pass, one key), and applies that pass's findings on `confirm` — never a fresh judgement. +A finding whose issues have moved on is skipped and said. It adds no "none" note to the backlog. + ## The import of hq's issues (slice 3) `issue-tracker.import` reads every `04-ISSUES/NNN-slug/00-report.md` of hq **through the records module @@ -127,6 +155,9 @@ verb takes an argument naming a caller, and none can be given one. ## Settings +`duplicate-check` (`on`; `off` stops the check on new issues) and `judge-model` (`sonnet`; `haiku` or `opus`) +steer the duplicate check. + ``` { "first-number": 365, diff --git a/modules/mesh-issues/cmd/mesh-issues/groom.go b/modules/mesh-issues/cmd/mesh-issues/groom.go new file mode 100644 index 00000000..4dd64a28 --- /dev/null +++ b/modules/mesh-issues/cmd/mesh-issues/groom.go @@ -0,0 +1,758 @@ +package main + +// The duplicate check (novox/hq ADR 0278, to-be 53 §9): when an issue is opened, the tracker asks the agent on +// its node whether an older issue that is not resolved already asks the same question, and acts only on a +// clear duplicate — the newer issue is closed wontfix as "duplicate of N", its report kept as a note on the +// older one, which never moves. `groom` runs the same judgement over the backlog, as a dry run kept in the +// state `grooming`, and applies that pass's findings on confirm. + +import ( + "crypto/rand" + "encoding/hex" + "encoding/json" + "errors" + "fmt" + "regexp" + "sort" + "strconv" + "strings" + "sync" + "time" + + stdio "git.novox.be/novox/mesh-sdk/go" +) + +// GroomBy is who acted, recorded on every note, link and move the duplicate check makes: not a caller of a +// verb, and not a name anybody can type (ADR 0278 §2). +const GroomBy = "duplicate-check" + +// GroomingState is the state that keeps the backlog's pass (ADR 0278 §6). +const GroomingState = "grooming" + +// passKey is the one key of `grooming`: the last pass. +const passKey = "pass" + +// The verdicts a judgement answers. +const ( + VerdictDuplicate = "duplicate" + VerdictRelated = "related" + VerdictNone = "none" +) + +// Bounds of the judgement's two questions (ADR 0278 §1). +const ( + // MostShortlist is how many issues the first question may name. + MostShortlist = 5 + // MostReportAsked is how much of one report the second question carries. + MostReportAsked = 8 << 10 + // MostTitlesAsked is how much of the question the candidates' titles may fill: under the judgement's + // 64 KiB, beside the new issue's report. + MostTitlesAsked = 48 << 10 +) + +// DefaultJudgeModel is the model asked when the setting names none. +const DefaultJudgeModel = "sonnet" + +// Judgement asks one question of the agent and answers the structured answer, and which model on which node +// answered it.
