cli-json-daily, spend-flow and cli-emitters spawn the real CLI per test
and blow the 5s default under full parallel suite load while passing in
isolation - the flake set #948 documented on unmodified main, observed
again locally (cli-json-daily) and in CI (cli-emitters on a green PR).
Same file-level remedy the CLI menubar suite already uses; the default
stays 5s for everything else.
The TUI comparison picker silently ignored --model-a/--model-b (only the
--format json path used them), and both paths required the canonical model
id verbatim with no way to pass the display name the picker itself shows
(e.g. "Opus 4.8" for claude-opus-4-8).
Adds findModelStat, a shared lookup that matches the canonical id first and
falls back to getShortModelName's existing canonical -> display mapping
(case-insensitive) rather than a new alias table. Both the JSON path and
renderCompare/CompareView now use it; renderCompare resolves --model-a/
--model-b up front and seeds CompareView's picked-models state so results
load immediately instead of showing the picker. Also validates "both or
neither" for the TUI (default) format, matching the JSON path.
Fixesgetagentseal/codeburn#767 (item 1).
The #782 titles threading added title to the sessions JSON row shape but
missed this emitter test's key list; caught by the first full-suite run
since the merge.
