Development record

The product thinker asked how a memory page larger than the recall's per-turn budget (about 64 KB) could come about, and why one would be needed. Pages are written by abcd library ingest, which fetches up to 10 MiB of a source, distils it into pages through a model, and writes them, and by hand; nothing holds a page to the recall's budget, and the store reads pages up to 4 MiB. So a long paper or web page can become one oversized page that the recall then sets aside, as PR #982 builds it. No such page is needed: the limit belongs where the page is made, not where it is read.
