--focus "<prose>" narrows the day plan to repos whose STATE.md DECLARES a
matching topic marker. Measured on the real tree: 26 blocks to 6.
The filter alone was never the feature. --plan documents that it takes one
position (the order), hides nothing, and labels what it cannot rank rather
than dropping it, so a silent cutoff would break a property the format had
already written down. The same run prints the slugs the prose resolved to,
how many blocks it removed, the repos that MENTION a resolved slug with no
marker line - named, not counted - and how many STATE.md it searched. Each
surviving block carries the declaration it survived on.
Enumerated rather than counted because the decisive find behind this feature
was invisible to every string measurement until the held-back population was
listed. "nevner", never "dekker": this reports text found, and board.sh has
no grounds for a claim about relevance. The slug vocabulary comes from the
scanned STATE.md themselves, so the "no other file" invariant survives.
Emitted as key=value, not '#' comments: the consumer's parser runs in
paragraph mode and drops any block without tab=, so a comment would reach the
operator on the terminal path and vanish on the driver path - the one case
where the cutoff is applied unseen.
board-selftest 89 -> 113. The narrowing check is comparative, since every
presence-only assertion passes against a no-op filter.
