Prompt

Open a new isolated worktree in the local Tractor repository and draft a fix for BroadcastReceiver reporting that a lagged one-slot consumer dropped zero values when one value had actually been displaced.

Response summary

Corrected the off-by-one lag count while preserving cursor recovery and added deterministic narrow- and wider-window regressions for exact loss reporting.

Files changed

• tractor/trionics/_broadcast.py - exact broadcast overrun count.
• tests/test_task_broadcasting.py - lag count and recovery regression.

Human edits
