Context

Found by /os-aidd-lint:mine-blindspots (f7c52e1) on 2026-07-26 — causal bucket (a): "rule exists, logic gap" — tier-1 cop bug, not new rule.

Summary

Both ListItems and StepBlocks regexes admit only digits or bullet symbols (-, *, +, \d+.). Lettered markers (a., b., d.) match neither regex, so lettered sub-items are invisible from their FIRST line — not merely their continuations (distinct from issue #2). This is a structural gap affecting two files.

Root cause

Code: plugins/os-aidd-lint/lib/aidd_lint/list_items.rb:7 and plugins/os-aidd-lint/lib/aidd_lint/step_blocks.rb:9

ListItems MARKER requires [-*+]|\d+\.
StepBlocks TOP_LEVEL_MARKER requires \A\d+\.\s+

Neither admits letters. Lettered markers like a., b., d. match neither and are completely invisible.

Observed missed instances

os-status/skills/fix/SKILL.md lines 52-60 (the "d." sub-step)
Downstream trailing-prohibition misses at lines 59-60 and 65 that follow from this root cause

Fix direction

Admit lettered markers in both regexes. This is one fix spanning two files.
