v0.6.4

Fixed

• Copilot token usage now records (was always 0). Copilot writes its token totals only in
  the trailing session.shutdown events line, ~1s after agentStop — usage was sampled before
  it landed. read_usage now polls the transcript for a short grace, driven by a new per-profile
  usage_grace_s (8s for copilot, 0 elsewhere = read once).
• Copilot multi-turn reviews no longer stall. agentStop fires per response turn, so a
  parallel-subagent review ends several turns and tripped the global stop_without_result_nudges
  default of 1. New per-adapter floor (5 for copilot), overridable per stage via [adapter.review].

Added

• [adapter] usage_grace_s / stop_without_result_nudges (base + per-stage
  [adapter.dev|review|triage]), editable in the settings TUI. Unset = inherit the CLI profile's
  shipped default.

Changed

• Copilot docs. Pin a capable model — the free GPT-5 mini default silently skips steps in
  multi-step dev/review — and it's the Copilot CLI binary that's supported, not the VS Code
  extension.
