alfabank.ru itself is unreachable from this environment, so addresses
came from the official regulator registry instead (cbr.ru/finorg/foinfo,
"Alfa-Bank subdivisions") — 981 addresses across 509 cities, one per
region sampled into benchmark-bank-context.txt (60 lines) as the
office-address trap the spec calls out explicitly.
Running them surfaced two real precision bugs, not just more test
data:
- ORGANISATION_NEARBY's veto window (80 chars) was too narrow for
official addresses that include a region name before the city —
"Отделение ... Республика Бурятия, г. Северобайкальск, ..." puts
the house number 80+ chars from the anchor. Widened to 150.
- The two dictionary-only FIO rules (surname + capitalized word,
no role word) had no address-context veto at all: "Великие Луки"
matched as the given name "Лука" plus a stray word, "Богдана
Хмельницкого" as a person because streets named after people are
syntactically identical to actual names. Added the same
ORGANISATION_NEARBY veto the address rules already use.
False-positive rate on the 60-address sample: 40.5% before, 0% after.
