Scenario 1b — a codemode round-trip: the script's duration is context
The agent loop in one exchange: the model answers with a codemode block; the worker (parsing is off in this project) extracts and requests the script; the capability host settles it; the worker renders the result back as developer context — INCLUDING HOW LONG IT TOOK — and that rendered result is what triggers the next turn. The duration matters to the model: it learns that listing PRs costs ~2s and can choose to batch, cache, or warn accordingly. Note which events are machinery (script-run-requested/settled — never model-visible; the worker derives the rendered duration from their two timestamps) vs the rendered consequence (@37). The send stamps show the same rhythm from the outside.
