The TS port passed the event ENVELOPE (data) instead of the model-visible
message (data.message) for assistant/message and tool/result — every such
node was priced at a flat 4 tokens (role framing only), so tool-heavy and
assistant-rich sessions were massively undercounted in the Current
composition. This is why the overview (20.4k) disagreed with the real
usage. Mirrors dsh's deriveEventMessage exactly now; empty-content
assistant messages price 0; tools total uses dsh's whole-array price; the
overview additionally shows the last provider-reported actual prompt
alongside the estimate.
