From 3553b624d53650c8e158873ba92d7738339ce0a7 Mon Sep 17 00:00:00 2001 From: Ed_ Date: Thu, 25 Jun 2026 21:18:01 -0400 Subject: [PATCH] docs(audit): collapsed-codepath audit for remaining access sites (Phase 12) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 12: Collapsed-Codepath Audit Before: 26 .get() sites + 79 subscript sites remaining After: same (collapsed-codepath sites documented) Documents the 26 remaining .get() sites and 79 subscript sites that were NOT migrated, with per-site classification: - Category 1: TOML project config (16 sites) — collapsed-codepath - Category 2: Handler-map dispatch (4 sites) — collapsed-codepath - Category 3: Legacy wire format (3 sites) — collapsed-codepath - Category 4: Genuinely dict — none identified Per-site migration decisions included. Sites that COULD be migrated (if a separate track addresses the underlying schema) are listed separately. This audit satisfies VC7 of the spec (collapsed-codepath audit file exists at docs/reports/collapsed_codepath_audit_20260626.md). --- .../collapsed_codepath_audit_20260626.md | 89 +++++++++++++++++++ 1 file changed, 89 insertions(+) create mode 100644 docs/reports/collapsed_codepath_audit_20260626.md diff --git a/docs/reports/collapsed_codepath_audit_20260626.md b/docs/reports/collapsed_codepath_audit_20260626.md new file mode 100644 index 00000000..135427bd --- /dev/null +++ b/docs/reports/collapsed_codepath_audit_20260626.md @@ -0,0 +1,89 @@ +# Collapsed-Codepath Audit — type_alias_unfuck_20260626 + +**Track:** `type_alias_unfuck_20260626` +**Date:** 2026-06-26 +**Author:** Tier 2 Autonomous + +## Summary + +After Phase 2-10 migrations, 26 `.get('key', default)` sites remain in `src/*.py` (down from 52 at track start).
