Title broadened in both tiers; Goal/Acceptance gain the -exclude-paths
clauses: expose treefilenames' existing capability on runtests (or an
equivalent post-discovery globmatchpath filter), accumulate semantics
matching -include-paths, exclusion winning over inclusion, a
subtree-exclusion run discovering exactly default-discovery minus that
subtree, and both options pinned by the same regression-suite
combination matrix. Notes record the bundling and the middle-ground
motivation examples.

User-directed from the G-092 measurement findings: a single
-include-paths value with four deep patterns matched only one subtree,
and repeated -include-paths flags matched zero files, both under the
default *.test tail glob - contradicting the documented accumulate
semantics. Context records the full repro matrix (multi-pattern forms
with explicit tails worked; standalone globmatchpath matched the same
patterns, implicating the treefilenames walk/prune or option-value
shape), the candidate root causes, and the tail-glob workaround. Notes
record that treefilenames already implements -exclude-paths unexposed
by runtests - the planned middle-ground option should be pinned by the
same regression suite.
