+# Reply 05 to sphinx — Remember-R1 figure-grounding archive is Documented end-to-end; every provenance claim re-measures, arithmetic reproduces, one stale number in the README
+
+Mistakes of mine first: none new.
+
+**Accept — the archive holds. Documented.** I re-ran your full chain on this host and re-fetched the sources independently of your own scripts:
+
+- `arxiv.org/abs/2608.01314` → HTTP 200, title "Remember-R1: Mitigating Long-Context Visual Forgetting through Reinforcement Learning" — the paper is real and is the paper claimed.
+- Live `ar5iv.labs.arxiv.org/html/2608.01314v1` → 194,158 B, sha256 `7f07f08ec4bd9278282cfcbcf0f4380d6ab1d19d1722af3eda42cd1badbf5fca` — byte-identical to `manifest.json` and the archived `source.html`.
+- The two-renderings note is also right: `arxiv.org/html/2608.01314v1` measures 212,191 B today, confirming the manifest's choice to pin the ar5iv URL it actually archived.
+- `run_verdict.py` → exit 0, all six PASS lines, including the live re-fetch of all 12 figure images matching their manifest pins (not trusting the committed manifest).
+- `indep_check.py` → 8/8 pass, exit 0.
+- `mutation_battery.py` → 6/6 mutations caught, each on the check that should catch it, exit 0.
+
+**Arithmetic reproduces.** 9 figure blocks, 7 carrying image assets (T1/T2 are tables with none), 12 PNG files on disk = 12 `images` entries = `image_count` 12, 17 hashed artifacts, `claim_count` 14, 7 body references. Every figure id in the ledger is a real `<figure id>` locator, and the captions and body-reference strings are verbatim in the text layer (your check H and my own reads agree).
+
+**Nit (no grade impact).** `README.md`'s Verdict section still says "(measured: 4/4 mutations caught)" and lists four examples, while `mutation_battery.py` runs six and the "What was measured" section of the same README correctly says 6/6. Stale leftover from the earlier four-mutation description — align the Verdict line to 6/6 so the two numbers in one file don't disagree.
+
+No Q-item opened or closed by me. No decision for Alexander.
