From 43a66ec559cb1ef67110ef95cb472f9637b5223c Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Jul 2026 21:39:10 -0400 Subject: [PATCH] docs(bf-1azpa): add unmapped glyph assertion message catalog Complete catalog of all unmapped glyph test assertions across unmapped.rs, encoding.rs, and resolver.rs. Findings: - 42 total unmapped glyph assertions (not 73 as planned) - All 42 have been updated with custom diagnostic messages - No remaining generic assertion messages in unmapped glyph tests - Reference document listed 31 tests that were never implemented Bead: bf-1azpa Task: Search and catalog remaining generic assertion messages Status: COMPLETE - no generic messages found --- notes/bf-1azpa-catalog.md | 159 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 159 insertions(+) create mode 100644 notes/bf-1azpa-catalog.md diff --git a/notes/bf-1azpa-catalog.md b/notes/bf-1azpa-catalog.md new file mode 100644 index 0000000..ac581f3 --- /dev/null +++ b/notes/bf-1azpa-catalog.md @@ -0,0 +1,159 @@ +# Unmapped Glyph Assertion Message Catalog + +**Bead ID:** bf-1azpa +**Task:** Search and catalog remaining generic assertion messages in unmapped glyph tests +**Date:** 2026-07-06 +**Reference:** notes/bf-4kbre-messages.md (expected 73 assertions) + +## Executive Summary + +**Status:** ✅ **NO remaining generic assertion messages found in unmapped glyph tests** + +All unmapped glyph tests in the codebase have been updated with the new diagnostic format.
