The bottom-right card no longer lists model-visible messages; it answers
what the agent DID to the user's files up to the picked step. Tool-result
nodes (live + archive) join the conversation snapshot for call arguments
and fold into one row per file with per-purpose counts (read/written/
searched), estimated line deltas from edit/write arguments, multimodal
and directory form glyphs, and failure dots. Header chips double as
purpose/form filters next to a path search box; a row expands into the
file's operation log, and each operation reveals the exact tool result
in the Context browser. The card scrubs live with the trend chart pick
(exclusive next-request bound); ops whose paths aged out of retention
are honestly counted in a footnote.
