A view that shows a text state as it is (pure_module_text_state) now goes
out as the state's stored extents, as a document read does: the answer
holds the store mapping, charged to the budget, until it is sent and its
ticket released; a state with edits not yet stored is copied as before.
Documents and views share one loan path, and the extent array grows as
needed. A 1 MiB note read by 8 connections: 776-817 answers a second

The load generator learns GET /views/page.

run.py --suite app serves the scoreboard of scores.aup (22 lines of aup)
with pure-serve against the same scoreboard written by hand in axum and
drogon: POST /inputs/score?points=N with a name as the body, GET
/views/total and a page of 20 rows as JSON. Durable, the baselines append
each score to a log and fdatasync it before answering (replayed at
start); the load generator learns the three requests.

A C load generator, an axum service with the same document contract (in
memory, fdatasync, and crash-safe replacement), and a runner that pins the
servers and the load to separate CPUs. On the Pi 5, Pure uses about 40%
less memory, wins with a new connection per request and with eight durable
writers (3.2x the crash-safe axum), but loses 5x on keep-alive reads and
1.5x on 64 durable writers: no persistent connections, one thread, eight
connection slots and two fsyncs per commit. Note 075 records the numbers
and the targets.
