e2e: crawl reset survives app navigation; dragoon docs carry the cut ledger

Two faces of the same verification round.

12-crawl returned to the homepage between links with a bare page.goto, and Plex
Web (signed out, so it renders its own sign-in iframe for its Plex-account flow)
keeps redirecting the top frame: Chromium cancelled our goto with
net::ERR_ABORTED, outside the try, so the whole crawl died — once as a 420 s
timeout in the deploy gate, once at 5.4 s on the same link. backHome() tolerates
that one error class and re-issues; any other error still propagates, and the
per-app verdict (guard settled, hostname, no authentik uidField, status < 500)
is unchanged. Plex was healthy throughout (container up 2 days, 32400 answering
HTTPS 401 / plain-HTTP empty reply), so this was app behaviour, not a fault —
recorded as gotcha 6 on the E2E page.

The 200,704 boot printed 5.5 GiB reserved and 74.1 GiB in all (not the ~5.4/~74
my arithmetic predicted), so every prose figure is re-keyed to the ledger, and
the runbook gains the second production-boot section: marker revision, pool
reservation, shape line, prompt-cache entry size, and the refusal contract at the
new ceiling (400 in 0.86 s naming 200704 and the 96,405-token overage, before any
prefill). Cost stated (two maximum-length conversations never coexist; the 180k
compaction target is unreachable inside a 155,648 window) and purchase stated
(1.7 GiB of page cache, 9.1 GiB against the 2026-10-06 shape).
