ClashGO v0.4.0-beta

Changed

• Frame-hot-path template matching is single-scale by default
  (internal/vision/vision.go) — MatchTemplate no longer blindly
  escalates every call to a 5-step multi-scale search (0.8–1.2). That
  escalation cost 5 Resize allocations + 5 cgo matches per call on the
  per-frame path. Callers that genuinely need density-scale tolerance
  call MatchMultiScale explicitly (named templates hit the scaled
  template cache). Expected effect: per-frame template matching cgo work
  drops from 5×N to N matches (N = templates checked).
• Pooled result Mats on the classifier and loot-OCR paths
  (internal/game/templates.go, internal/game/loot.go) — the result
  Mat for MatchTemplate results now comes from the shared vision Mat
  pool (vision.GetMat/PutMat) instead of gocv.NewMat() + Close()
  per template per frame. Zero result-Mat heap allocation on the
  classifier tick and loot OCR hot paths.
• Persistent ADB shell pipe is now enabled by default
  (internal/config/config.go) — UseShellPipe: true. Removes the
  ~100–300ms app_process JVM spin-up per tap during attack cycles
  (measured 30–80ms/command on USB, more on WiFi ADB). Automatic
  fallback to the legacy one-shot transport is verified
  (routeTap → markPipeBroken → legacy tap path), and pipe start
  failure logs a warning and degrades gracefully.

Fixed

• --once CLI runs now exit cleanly (cli.go, internal/bot/bot.go)
  — main() previously blocked forever on ctx.Done() after the bot
  finished its final attack, so a --once run hung with the process
  alive after the session summary printed. Bot.Done() exposes a
  channel that closes on graceful attack-cap shutdown, and main()
  selects on it.
• Boot survives a wedged wm size (internal/bot/bootorchestrator.go)
  — when the wm size shell call fails (BlueStacks returning
  "ADB: closed" while SurfaceFlinger still serves frames), the boot
  orchestrator now falls back to the live screencap's 12-byte header
  for authoritative pixel dimensions instead of aborting the whole
  boot and leaving the Start button dead.

Verified

• Full end-to-end live run on BlueStacks Air (860×732): boot → calibrate
  → attack search → loot OCR → EDrag Rush attack (100% deploy, 3 stars,
  2.1M elixir) → graceful shutdown, exit code 0.
