Generation offers active registered tools through positional system entries and
hands a tool-calling answer to parallel or sequential pi.tool tasks and a
pi.post-tools task that applies addTools/terminate and continues the run. Tool
tasks validate, run beforeTool/afterTool, record intent with the replay policy,
publish bounded, sanitized, adaptively throttled progress in pi.live.tools, and
write results with a rendered diagnostics block. Hook dispatch with conversation
and subtree scopes, prepareArguments, HarnessOptions.env, and read/bash/edit/write
tools in pi-durable/tools. The env shell now streams raw output and spills past
thresholds; its bounded capture and publisher are removed.
Port and extend the agent environment tests for NodeExecutionEnv, output
capture, adaptive publishing, and truncation, including exact-byte
truncation, flushing, line-reader cancellation, spill backpressure, and
Buffer-free UTF-8 counting.
Fix truncation reporting when bytes and lines are both exceeded, when only
bytes are exceeded at the line cap, and when small limits trim multi-byte
edge characters. Report the full size of oversized newline-terminated tail
lines. Resolve durable test imports from source so tests run unbuilt.
Set Pico tool output defaults to 50 KiB and 2,000 lines.
