# Plan: Additional rules 71–80 (ROADMAP)

**Source:** [ROADMAP.md — Additional rules](../../ROADMAP.md#additional-rules).  
**Note:** The Additional rules table currently has 69 rows (1–69; row 69 = avoid_unstable_final_fields, removed). So “remaining” rules = 58 (rows 11–68). Plans 11–20 through 61–70 therefore cover all 58 remaining rules. This file (71–80) is **reserved for future expansion**: if more rules are added to the ROADMAP table, use this plan for the next batch of 10, reusing the structure of [plan_additional_rules_11_through_20.md](plan_additional_rules_11_through_20.md) (Summary, Target file, Approach, Acceptance criteria, Quick fix, Checklist).
