v0.99.72

• Happy Hare selector manual controls — the AMS sidebar and slot context menu now expose Happy Hare's selector operations directly: Select gate (MMU_SELECT), Check this gate / Check gates (all) (MMU_CHECK_GATE), discrete servo positions (MMU_SERVO POS=), a selector jog, and a runtime gear-sync toggle ("Sync during printing"). The sidebar reset button is relabeled per backend ("Home" on Happy Hare), the selector/hub box is clickable with a gear affordance, and a new capability-gated selector context menu shows only the operations the backend supports. Selector actions report feedback through the AMS status display, including a brief "Recovering" status while Happy Hare's recover runs.

• Richer crash diagnostics for blank aborts (#987) — the crash handler now captures the std::terminate reason and abort_msg_state for otherwise-blank SIGABRTs, plus recent ERROR log lines and an lv_assert breadcrumb, and the g-code viewer breadcrumbs its streaming render range. resolve-backtrace.sh gains a --bundle mode with call-spine extraction.

• Presets can seed device-level touch calibration — a preset's top-level input block (e.g. a known-good touch matrix) now deep-merges into settings before the wizard runs, without clobbering values the user already set.

• Temperature graph no longer freezes touch on low-power displays (#979) — the per-column gradient is rendered once into an offscreen buffer and blitted on unchanged redraws, eliminating the ~2–3s touch stall seen on the K2 Plus from repainting it every frame.

• Snapmaker ACE Pro unload retracts correctly (#974) — unload routes through AUTO_FEEDING UNLOAD=1, symmetric with load, instead of the low-level inner-filament primitive that left filament un-retracted.

• PID/MPC calibration survives slow-cooling beds (#988) — the timeout is raised to 20 minutes and the collector keeps listening past the RPC timeout, so large/slow beds finish instead of timing out mid-tune.

• Theme falls back to default colors for missing or empty keys (#989) — incomplete custom themes no longer render with broken/blank colors.

• Print-select no longer logs an LVGL warning for files without a thumbnail (#990).

• Button contrast recompute guarded against widget address reuse (#924) — a deferred contrast pass can no longer apply to a different button that reused the same address.

• G-code viewer joins its ghost-render worker before mutating shared state (#987) — closes a race on the color/exclude state during ghost rendering.

• LVGL patch set updated — backported LV_CHECK_ARG argument guards (global via lv_assert.h), fbdev arg-guard parity, and a drag-scoped slider patch.
