docs: optimistic-accountability essay reflects entry 13 live (drill catch)

The header still called the essay a 'parked blog-post source' awaiting
entry 13, and two future tenses ('will carry') survived — the blog is
published and entry 13 is live. Caught by a fresh-pattern sweep after
the hand-picked patterns of the first documentation pass missed them.

 # Optimistic by construction: what the LTL holds, and what it shares with rollups
 
-Status: essay / parked blog-post source. Per the operator's decision,
-the blog version publishes only AFTER entry 13 is live (runbook B7),
-when the closing claim — "the log carries kernel-checked proofs of its
