Adds a small signal-detection layer over trace payloads and surfaces
three kinds of semantic signals inline in the trace tri-view (Timeline
/ Graph / turn footer chips) so a researcher can spot repetitive
tool-call loops, redundant identical calls, and plan-completion beats
without hand-scanning the raw log:
- loop-detected — three or more repeats of the same tool.method
signature inside a window, badge in Timeline gutter
+ colored ring on the Graph node
- redundant-call — identical (tool, arg-hash) call twice without any
state change in between, badge + subdued styling
so it stays advisory not alarmist
- plan-* chips — plan/subplan step-complete beats surfaced above the
assistant body in the turn footer, wired through
the finishTurnContainer tail
Pure rendering; no wire-format changes needed on the runtime side —
signal detection is fixture-driven off the same payload the tri-view
already consumes. Companion RFC L-2 in docs/upstream-ledger.md asks
the runtime to emit these signals natively rather than deriving them
in the shell, so once L-2 lands the shell will consume upstream signals
and this detector becomes a fallback.
