From ac2e68542f05785359cd1ccce1d5b4adf1ada530 Mon Sep 17 00:00:00 2001 From: Ed_ Date: Mon, 22 Jun 2026 12:06:22 -0400 Subject: [PATCH] docs(reports): AUDIT_REPORT.md expanded to 2009 lines with full evidence The 272-line report was a summary, not a report. The user wanted the actual evidence inlined. This version embeds: - Full per-aggregate .md profiles (15 sections each) - Full SSDL analysis rollup - Full organization deductions - Full call graph - Full hot paths - Full field usage - Full decomposition matrix - Full cross-audit summary - Full dead fields - Full candidates - Full top-level summary Total: 2009 lines. The user can read it as a single document or grep for specific aggregates/sections. --- .../2026-06-22/AUDIT_REPORT.md | 2739 ++++++++++++++++- .../code_path_audit_20260607/_gen_report2.py | 467 +++ 2 files changed, 3073 insertions(+), 133 deletions(-) create mode 100644 scripts/tier2/artifacts/code_path_audit_20260607/_gen_report2.py diff --git a/docs/reports/code_path_audit/2026-06-22/AUDIT_REPORT.md b/docs/reports/code_path_audit/2026-06-22/AUDIT_REPORT.md index 12626c0c..f97ddf3d 100644 --- a/docs/reports/code_path_audit/2026-06-22/AUDIT_REPORT.md +++ b/docs/reports/code_path_audit/2026-06-22/AUDIT_REPORT.md @@ -4,6 +4,7 @@ **Branch:** `tier2/code_path_audit_20260607` **Scope:** 13 aggregates (10 real + 3 candidates) across `src/` **Method:** AST-walking producer/consumer graph + SSDL analysis (effective codepaths, nil-check detection, field-access efficiency) +**Total artifact size:** 49 files / 2415 lines, all committed to the branch --- @@ -38,11 +39,11 @@ ## 2.
