open_agh_chemistry_pl: pin the four rights pages in a licence-evidence file

Adds data/open_agh_chemistry_pl/open_agh_chemistry_pl.license-evidence.json
(URL, retrieval time, EPUB and rights-page sha256, quoted CC BY-SA 4.0 line per
book, Wayback status, chain with V/I marks, not_checked) and a contract test
tying it to books.json, the registry entry and the parquet. No data change.
No Wayback snapshot of any rights page exists; recorded, not archived.

+## `open_agh_chemistry_pl`: rights pages pinned, no archive copy exists
+
+**Investigated:** 2026-10-06
+**Verdict:** no data change; 370 documents stay CC BY-SA 4.0. The licence evidence is now in
+`data/open_agh_chemistry_pl/open_agh_chemistry_pl.license-evidence.json`. Tracks the 2026-10
+rights audit action "archive the rights pages".
+
+### Verified
+
+- Re-fetched the four EPUBs (`/rpc/preview/handbooks/{29,1394,37,1893}/epub/light`) on
+  2026-10-05 23:38 UTC. EPUB and `OEBPS/main.xhtml` sha256 equal the values recorded on
+  2026-09-05, 4/4.
+- Each rights page says "Publikacja udostępniona jest na licencji Creative Commons Uznanie
+  Autorstwa - Na tych samych warunkach 4.0." and links the 4.0 deed. No NC marker, no "3.0".
+
+### Not established
+
+- No Wayback snapshot of any rights-bearing URL exists (CDX lookups, read-only; no Save Page
+  Now). The `/handbook/{id}` landing pages are archived, but they are a ~3 kB shell without
+  licence text. A later relabel of the rights pages cannot be ruled out; the bytes are pinned
+  by sha256 instead. A written confirmation from AGH would close the gap.
+- Whether AGH holds every module's rights (no contract seen).
+
+**Lesson:** an archive copy was the expected fallback for a licence page, and it did not
+exist. Pin the bytes when the source is first read.
