From e2e3f044e27b16945d5748ca5501d5fdfe5dc071 Mon Sep 17 00:00:00 2001 From: tzhouam Date: Thu, 10 Sep 2026 12:03:14 +0800 Subject: [PATCH 1/2] sdk(knowledge): reject rule IDs that already head a section on any catalog page Rule IDs are auditable tree-wide: Direct routing resolves a rule by exact ID, and since #136 widened the catalog an owner's topic pages share the owner's ID prefix. The curator only checked the target page, so the first auto batch on the widened catalog (#140) reused `DIFF-2y` (already in rules-checkpoint-loading.md) and `DIFF-4w` (rules-worker-observability.md), and the parked 09-08 batch reused four more. Searches and exact-ID routes then return two unrelated rules for one ID. validate_proposals now scans every catalog page in scope once, rejects a proposal whose ID heads a section on another page ("rule_id already exists on "), and rejects a second proposal in the same batch that reuses an earlier accepted ID on a different page. The same-page rejection reason is unchanged. The prompt contract states the tree-wide rule so the model picks a fresh ID instead of burning a repair round.
