helm: Run 23 landing evidence -- readback at eec3ff3 over the raw COMMIT path, three rows served = disk = git (record 20820 / 8d67248f, WORK-QUEUE.md 962664 / 972efe4a, check-in 18265 / 45223797), artifact out/R23-READBACK.json 1229 B / sha256 9846ea9050802ca24d67a869e4facae7c750ee6a0bdbe3c8a9b07bd808372c18. The check-in's own row defers to the artifact because appending this block changes its digest; the artifact's revision field dates each row. Live state unchanged (snapshot 14039 / aa842b0f / mtime_ns 1791479579475780303; held pin 120 / 5b6d7071 / 1791478687099553071; ctime unmoved this run), deployed /root/.helm/bin/ untouched with HELM_COLLECTOR count 0 so Q40 stands, sandbox census 0 in the q55 tree, nothing deployed, decisions/ and inbox/ untouched, no another-party file edited, no secret printed.

+**This file's own row defers to the artifact above** — appending this block changes this file's digest, so
+the row for *this* commit is the next revision's readback and the chain stops here by design (Run 22's
+landing-fill shape, with the regress named instead of chased). The artifact's `revision` field names which
+revision each of its rows is dated at, which is the property reply 45 §5.1 asked for.
