훑어서 세, 절대 기억으로 세지 마

# 1. BY SYMBOL - finds every site that imports the shared component.
#    Right answer once the convention has one name. Blind to any
#    copy that was renamed on the way in, which is what hand-copied
#    conventions always are.
grep -rl "KitPippaSidekick" <each repo's source root>

# 2. BY CONCEPT NAME, case-insensitive, on FILENAMES. This is the
#    one that found the fourth adopter: it had been renamed to the
#    app's own vocabulary, so no symbol search could reach it.
find . -iname '*sidekick*' -not -path '*/node_modules/*'

# 3. BY AN UNUSUAL IMPLEMENTATION LINE. A distinctive constant, CSS
#    variable, or storage key survives renaming, because renaming a
#    file is easy and renaming its guts is not.
#    (-e marks each pattern: a pattern starting with "--" would
#    otherwise be read as an option and the search would never run.)
grep -rn -e "--sk-offset-right" -e "sidekick.width" . \

# The check that closes the loop: every hit from ANY instrument must
# appear in the ledger, and every ledger row must have a hit.
#
#   comm -3 <(sweep_results | sort) <(ledger_rows | sort)
#
# Empty output means the document and the filesystem agree. Anything
# printed is either an unlisted adopter or a ledger row describing
# something that no longer exists - and both are worth knowing.
