InstrumentDetailView no longer wraps with .padding(8). Each config
view declares its own padding. Form views pad all four sides;
editor views (Tracer hook editor, Custom Instrument source) leave
the trailing edge flush so the scrollbar reaches the window edge.
- Store source files as named CustomInstrumentFile rows per def
- Render sidebar with disclosure groups
- Drive editor via Monaco project models with activePath
- Validate Add/Rename/Delete dialogs and submit on Enter
- Fork installed hook packs into editable custom instruments
- Reload instances on def change; clear stale compat reasons live
- Focus editor on selection (native + Monaco)
EngineRegistry caches one Engine per working-project URL.
MainWindowView.init does a pure lookup, so SwiftUI's
view-tree re-evaluations cannot open extra ProjectStores
that race the live one's BEGIN IMMEDIATE and crash via
try!.
UI-state persistence (collapse flag, sidebar selection,
session detail section, etc.) lives on Engine for GTK to
adopt. SQLite has a 5s busy timeout. Engine open failures
surface as an error view.
TargetPicker is host @State injected via environment.
Global instrument-UI defaults register at app startup;
per-engine instrument and local-notifier hookups live in
Engine extensions.
Engine owns the widget state cache, applies inbound updates from
the agent, persists session-scoped widgets, and broadcasts to
collaborating peers (action invocations route to the host).
Renderers in both UIs read the cache and the unified update
stream, with a Clear button that propagates to peers.
Agent SDK adds ctx.widget(id) with push/upsertItem/removeItem/
clear, plus a typed onAction handler. create() now takes a
restored snapshot seeded from persisted state and the join
snapshot.
Per-def .d.ts narrows the widget map, restored shape, and action
union to the exact ids declared in the editor.
Hookpack manifest mirrors CustomInstrumentDef: rich features,
TypeScript entry, optional file-based icon. Folder name is the
pack id.
HookPackConfig holds FeatureState per feature, producing the
same agent-JSON shape as custom instruments. Hookpack sources
compile through the shared TypeScript pipeline.
Import sits next to "New Custom Instrument..."; Export on the
custom-instrument context menu. Both UIs.
Render top-level boolean features as inline checkbox-style
toggles. Object fields use a SwiftUI Grid with a shared
right-aligned label column. Editors cap at sensible widths
(320 for string/regex, 200 for combo, 140 for numbers) and
push the rest of the row to a trailing spacer.
