+description: Parse one eRob robot joint module model and generate internal similar-model candidates from the packaged v3.1 recommendation rule source. This skill does not query inventory, ERP, production, purchasing, lead-time, or customer commitment data.
+---
+
+# Joint Module Model Recommendation
+
+## Purpose
+
+Generate internal similar-model candidates for one eRob joint module model.
+
+## Rule Source
+
+Use the packaged local rule file:
+
+```text
+capabilities/am516-delivery-prediction/rules/eRob关节模组相似型号推荐规则_v3.1.md
+```
+
+If the rule file is missing, stop.
+
+## Boundary
+
+- Output is internal candidate only.
+- Do not query API, ERP, inventory, purchasing, production, or lead-time data.
+- Do not write "can directly replace", "committed", or "can deliver".
+- The original model is the baseline.
+- Candidates require customer confirmation and AR516 or authorized human review.
+
+## Input
+
+Accept one model only.
+
+Example:
+
+```text
+eRob90H100I-FHM-18CT[V6]
+```
+
+## Core Constraints
+
+Strong constraints must stay unchanged:
+
+- outer diameter;
+- gear ratio;
+- installation;
+- communication;
+- output shaft.
+
+Allowed upgrades:
+
+- brake `F -> B`;
+- encoder upgrade only, never downgrade;
+- sensor `N -> T`;
+- standard grease to low-temperature grease;
+- DZ and LF brand may be candidates.
+
+## Full Candidate Generation
+
+- Keep outer diameter, structure, gear ratio, installation, communication, output shaft, and version unchanged.
+- Generate the full Cartesian set across every allowed value for brake, encoder, sensor, grease, and DZ/LF brand.
+- Encoder options are directional: `S -> M/HS/HM`, `M -> HS/HM`, `HS -> HM`, and `HM` has no further automatic upgrade.
+- Include the original model separately as the baseline and deduplicate all generated models.
+- Never generate a brake, encoder, sensor, or grease downgrade.
+- Query every generated candidate through the controlled delivery-prediction script.
+- Show candidates with usable lead-time summaries in full; summarize missing or unsupported models under `不可用候选`.
+
+## Output
+
+Use a vertical list with:
+
+- model;
+- candidate type;
+- difference;
+- recommendation reason;
+- customer confirmation item;
+- human review item.
+
+Format the difference field as `字段 原值→新值`. Join multiple changes with the Chinese semicolon `；`, for example:
+
+```text
+差异项：编码器 HS→HM；品牌 DZ→LF
+```
