+# Whole-Machine Fragment Sweep: 2026-07-14
+
+## Scope
+
+Bounded read-only scan of `Documents`, `WorkBuddy`, `.workbuddy`, `Downloads`,
+`Desktop`, and Codex attachments. Search depth followed the command set in
+`pre_work_error_ledger.md`.
+
+## Runtime Truth
+
+- Primary source/runtime repo: `/Users/wuyongnaren/Documents/印度占星`.
+- Active branch at scan time: `codex/release-hygiene-ci`.
+- `.workbuddy/skills/jyotish-vedic-astrology` is an unversioned historical
+  distribution mirror. It is never a runtime source or merge source.
+
+## Divergent Repository
+
+- `/Users/wuyongnaren/WorkBuddy/2026-07-05-19-03-49/yinduzhanxing` is a Git
+  checkout of the same remote, on `main` at `8b53983`.
+- It is not a clean fast-forward copy of the active source branch. Symmetric
+  comparison against active source commit `c5404ec` found 432 source-only and
+  390 WorkBuddy-only commits, with merge base `a5bbba2`.
+- No files were copied, merged, deleted, or treated as authoritative.
+
+## Classified Artifacts
+
+- Desktop and Obsidian contain personal reports and research notes. They are
+  private reference material, excluded from public release and source imports.
+- Main repo contains benchmark outputs, raw local smoke artifacts, and clean
+  release trial material. They remain subject to existing privacy scan and
+  `.gitignore` boundaries.
+- Existing local planning, benchmark, and real-case drafts in the active repo
+  remain uncommitted and were not changed by this sweep.
+
+## Required Guard
+
+1. Before adapter, oracle, release, or entrypoint work, read this sweep plus
+   the two earlier sweep records.
+2. Do not merge or copy from the WorkBuddy checkout without an explicit,
+   commit-by-commit review and a separate branch.
+3. Do not publish private desktop/Obsidian reports or use them as test fixtures.
