Ran a two-agent parallel workflow to refine the four T-403 children against
the actual code, appending a sharpened scope / acceptance-criteria / files /
dependencies / open-questions block to each:
- T-404 (ctrl+w window family), T-405 (tab cycle + gt/gT),
T-406 (normal-mode list/scroll nav), T-407 (ex `:` overlay).
Both agents independently surfaced the shared structural blocker — no global
multi-chord SequenceMatcher exists today (the global key path is single-chord;
only the editor has a matcher) — and a recommended sequencing, now recorded as
a coordination note on the parent T-403 (build the matcher once; T-406 first).
Also files T-419 under the UI tracker (T-276): keep the workflow run card's
agent rows + usage visible while collapsed.
