Alpine.js adapter for @stainless-code/alpine-layers; plugin magics, x-layer-outlet, layerStack data, and JS hooks for typed layer stacks
Angular adapter for @stainless-code/angular-layers (signals + DI + imperative renderStack); use when wiring provideLayerClient, renderStack/useStackHandles, useLayerGroup, useMutationFlow, or createStackHook
UI-agnostic layer stack engine for @stainless-code/layers. Use for opening layers imperatively from anywhere, ordered named stacks, typed await or fire-and-forget calls, lifecycle control, blockers, validation, singleton updates, serial or nested layers, multi-stack orchestration, or building a library/framework adapter.
Lit adapter for @stainless-code/lit-layers; open UI from anywhere and manage ordered, named stacks with typed or fire-and-forget `open` via Reactive Controllers and custom elements
Preact adapter for @stainless-code/preact-layers — use for awaitable confirm flows, singleton toasts, nested drawers, stack subscriptions, and custom layer hosts
React adapter for @stainless-code/react-layers; open UI from anywhere and manage ordered, named stacks with typed or fire-and-forget `open`

A discipline for hard bugs. Skip phases only when explicitly justified.
When exploring, read docs/architecture.md (core/adapter seam + layer lifecycle) for module vocabulary before forming hypotheses.
Feedback loops (prefer in order):
bun test — co-located packages/*/src/**/*.test.ts at the core + adapter-binding seam (fastest; no DOM)bun run test:dom — packages/*/tests-dom/** for real-renderer reactivity, outlet/render surfaces, and ergonomic wrappers per adapterLayerClient / LayerStack and drive open / dismiss / scope / gcTime without any framework to reproduce phase / queue / cache paths without a real rendererdismiss/dismissAll ordering replayed through the isolated harnessThis is the skill. Spend disproportionate effort here. A tight pass/fail signal for this bug beats staring at code.
Done when you can name one command that is red-capable, deterministic, fast, and agent-runnable (bun test <file> or bun run test:dom -- <pattern>). No red-capable command → no Phase 2.
Run the loop; shrink to the smallest scenario that still goes red. Every remaining element must be load-bearing — one stack, one layer, one open/dismiss sequence, one selector.
Done when: minimal repro documented; non-load-bearing steps removed.
Generate 3–5 ranked, falsifiable hypotheses. Show the list to the user before testing. Bias toward the seams: snapshot referential-stability across notifyManager.batch, AbortController cancel-on-dismiss racing loadFn, scope-queue drain ordering on dismissAll, gcTime cache restore on re-open, selector identity causing useSyncExternalStore loops.
Done when: user has seen ranked list before any fix attempt.
One variable at a time. Tag debug logs [DEBUG-xxxx] for cleanup. Perf bugs (snapshot rebuild churn, scope-queue thrash, gcTime cache miss storms): measure first, then bisect.
Done when: one hypothesis confirmed or all falsified with evidence.
Regression test before the fix when a correct seam exists — co-locate under packages/*/src/ (bun test) or packages/<fw>/tests-dom/ (test:dom) per the test matrix in docs/architecture.md. If no seam exists to test through, document that as an architectural finding (a shallow module worth deepening behind a smaller interface) and track it in docs/roadmap.md.
Done when: loop is green; regression test added or gap documented.
Remove [DEBUG-...] logs, delete throwaway harnesses, state the winning hypothesis in the commit message. If prevention needs an architecture change, record specifics in docs/roadmap.md.
Done when: no debug sediment; commit message states root cause.
