Fix Buffer size setting never being applied; add Safety Switch control type

2026-09-21T06:16:15Z

- Buffer size (samples) in Settings > Acquisition was captured into the settings dict but never read anywhere — SignalBuffer always used the hardcoded MAX_BUFFER=20_000 constant (which happens to match the dialog's default, hence it looking like the value "reverts"). Add AcquisitionEngine.set_buffer_size(), wired in on startup and on Settings apply; existing buffers are rebuilt at the new size in place, keeping their most recent samples. - New "Safety Switch" control type: an On/Off Switch that's disabled outright until acquisition is running, with a lock icon shown while disabled. AcquisitionEngine gains a run_state_changed(bool) signal (emitted from start()/stop()); ControlWidget gains a _check_safety_lock() hook (no-op by default, called uniformly by ControlPanel on every widget) that SafetySwitch overrides. engine is now threaded through to every ControlWidget for this. Persists via ControlSpec.control_type alone — no schema change needed. Co-Authored-By: Claude Sonnet 5

Make Channel the single source of truth for a reading's name

2026-09-21T04:30:13Z

Device tab stays hardware-only (pins, wiring, may vary per workstation); the Channels window owns the profile-facing identity. Concretely: - Fix a real regression: SerialDevice generic-format Apply & Reconnect nulled out custom channel_names/units every time (no fallback, unlike every other optional field in reconfigure()), silently reverting to sig0/sig1/... ids. - Plot legend now live-tracks the current Signal/Channel name instead of freezing tr.label at add-time, so a rename shows up without re-adding the trace. - Add an inline quick-reconnect (combo + button, pre-selects the actual current source) directly on each Channel block in the Channels window, for the common single-source case — rewiring hardware no longer means touching every Plot/pipeline that referenced it. - Collapse the Channel ID field behind an "ID ▸" advanced toggle; channel_id is already auto-derived from the name (_slug_id) and rarely needs to be seen. - Devices tab's Signal "Name" column relabeled "Label" with a tooltip — de-emphasized now that Channel name is the real identity. - Move "create a Channel from this Signal" from a column on the Devices tab's signal table to a ⊕ button on each Signal row in the Channels tab's Namespace panel — the action now lives where the identity is created, not on the hardware tab. Only that instance opts in (on_create_channel); the read-only Namespace dock on the main window is unaffected. - Floor the Namespace panel's width at its columns' natural size so dragging the Channels-tab splitter narrower can't push the ⊕ column behind the horizontal scrollbar. - Breadcrumb log when a profile-saved Signal override can't be applied because the signal_id no longer exists.

Fix Signal name reset and orphaned references on device reconfigure

2026-09-20T17:31:07Z

Apply & Reconnect rebuilt a device's whole Signal list from hardware defaults on every call, silently discarding user/profile-set names, units, and colors even when pins hadn't changed. Add merge_signal_metadata() and call it from ArduinoDevice.remap_pins() and SerialDevice.reconfigure() to reapply the same fields ProfileManager already treats as user overrides, keyed by signal_id. Also close a related gap: removing a pin that a Channel/Plot/Control still referenced left it silently dangling, and SignalProcessor never pruned its latest-value cache, so a derived Channel kept computing off a permanently frozen stale reading. Add SignalProcessor. on_device_reconfigured() to purge that cache, reference_registry. find_references() for a console breadcrumb, and live "missing source" indicators on Plot traces and Channel blocks reusing ControlWidget's existing stale/QSS pattern. Also fixes ControlWidget._write() still enqueuing writes to a channel that no longer exists. Co-Authored-By: Claude Sonnet 5

Redesign Signal/Channel naming and fix pin-remap breaking references

2026-09-19T23:38:07Z

Arduino analog Signal ids used to be the pin name itself, so fixing a wrong pin silently changed the id and orphaned any plot trace, control, or filter pipeline pointing at it. Analog Signal ids are now positional (ai0, ai1, ...) and decoupled from the underlying pin, matching how digital I/O already worked. More broadly, formalizes a Device -> Signal -> Channel -> Plot naming model (SignalConfig for physical device channels, Channel for derived/ computed ones) and adds core/reference_registry.py to propagate any Signal or Channel id rename through plot traces, controls, and filter pipelines instead of leaving them dangling. Signal ids are now editable in the Signals tab with the same propagation. .labui profile schema bumped to v2.0 with a transparent migration for old files, including remapping old pin-name Signal ids to the new positional ones. Removed six confirmed-dead files (two legacy device classes, four superseded top-level ui/ duplicates).

Add .labui file association — open by double-click, cross-platform

2026-08-17T16:01:59Z

Windows/Linux self-register via core/file_association.py (winreg / XDG .desktop+mime), triggered from a new Settings button since there's no installer to do it at install time. macOS gets it at build time via labui.spec's new BUNDLE() step (CFBundleDocumentTypes in Info.plist) — that step also makes mac builds a real .app bundle for the first time, not just a bare onedir folder. main.py gains a LabUIApplication subclass to catch the macOS QFileOpenEvent (buffered if it arrives before MainWindow exists) plus argv[1] handling for Windows/Linux. ProfileButton.load_path() extracted so both paths share the same load-and-apply logic as the existing file-dialog flow. Co-Authored-By: Claude Sonnet 5

Channels tab drag-to-reorder, Namespace absolute references, fix stale Channel ID renames

2026-08-13T19:39:25Z

Generalized the Plot pane drag-to-reorder (_PaneDragHandle/_PlotDropContainer -> _DragHandle/_DragReorderContainer) and reused it for the Channels tab's derived-channel list; reordering also updates SignalProcessor's evaluation order (list order matters for chained Channels) via new reorder_derived(). Namespace panel: added an ID column (bare channel_id, matching the actual channels.get(...) script convention) and fixed the Source column for Channels to show resolved absolute references (dev_id/ch_id for a Signal, bare id for a chained Channel) instead of the operation kind, so a chain is traceable by eye. Fixed a real bug this surfaced: renaming a Channel's ID never propagated to other Channels' sources, leaving dangling ("derived", old_id) references that silently stopped updating. Added SignalProcessor.rename_derived() to fix up sources plus carry the ring buffer/latest-value cache to the new key, wired to DerivedBlock's Apply. Co-Authored-By: Claude Sonnet 5

Re-detect serial device ports by identity when a profile loads on another machine

2026-08-13T17:09:03Z

COM/tty numbers aren't stable across machines or replugs. Devices now save their USB serial number and OS description alongside the port; on profile load, if the saved port isn't present, ArduinoLayer.find_port_by_identity() looks for a match and remaps it. Falls back to the saved port (device shows ERROR) if nothing matches. Co-Authored-By: Claude Sonnet 5

Finish multi-platform release restructuring (previous commit was incomplete)

2026-08-11T17:36:10Z

git add silently staged nothing from the previous attempt because one pathspec in that batch (scripts/release/repository, already moved) no longer existed — only the .gitignore-adjacent renames landed. This commit adds what was actually meant to go in: - core/updater.py: releases/download/updates-/ instead of a single shared updates/ tag. - labui.spec: bundles root.json from this platform's own tree. - scripts/release/repo_init.py, repo_release.py: auto-detect platform, operate inside scripts/release//. - .gitignore: per-platform ignore rules (previous commit only carried the file renames, not this). - docs/building.md, scripts/release/README.md: rewritten for the per-platform flow. - Also picks up pre-existing local TUF re-signing (new snapshot/ timestamp signatures, bumped expiry/version) that was sitting uncommitted before this restructuring started.

Add dockable Namespace panel — live Python-namespace browser

2026-08-10T22:45:37Z

New right-docked panel (mirrors Control Panel's dock, opposite side) listing every Signal, Channel, and shared `vars` key currently in the profile, with live values and a double-click-to-copy reference snippet (vars.get(...) / channels.get(...)) for use in scripts. Closed by default — opt-in config tool, no collapse-strip nag like Control Panel gets since it's not needed mid-run. Also moves Configuration out of the View menu into its own toolbar button, and makes table row hover match the selection highlight color. Co-Authored-By: Claude Sonnet 5
