- suspense render-dom form: shows fallback while resource loads, swaps
to body content when resource signal resolves
- resource async signal: wraps promise into signal with loading/data/error
dict, auto-transitions on resolve/reject via promise-then
- transition: defers signal writes to requestIdleCallback, sets pending
signal for UI feedback during expensive operations
- Added schedule-idle, promise-then platform functions
- All Phase 2 features now marked Done in status tables

- :class-map dict toggles classes reactively via classList.add/remove
- :style-map dict sets inline styles reactively via el.style[prop]
- ref/ref-get/ref-set! mutable boxes (non-reactive, like useRef)
- :ref attribute sets ref.current to DOM element after rendering
- portal render-dom form renders children into remote target element
- Portal content auto-removed on island disposal via register-in-scope
- Added #portal-root div to page shell template
- Added stop-propagation and dom-focus platform functions
- Demo islands for all three features on the demo page
- Updated status tables: all P0/P1 features marked Done

- Effect and computed auto-register disposers with island scope via
register-in-scope; dispose-islands-in called before every swap point
(orchestration.sx) to clean up intervals/subscriptions on navigation.
- Map + deref inside islands auto-upgrades to reactive-list for signal-
bound list rendering. Demo island with add/remove items.
- New :bind attribute for two-way signal-input binding (text, checkbox,
radio, textarea, select). bind-input in adapter-dom.sx handles both
signal→element (effect) and element→signal (event listener).
- Phase 2 plan page at /reactive-islands/phase2 covering input binding,
keyed reconciliation, reactive class/style, refs, portals, error
boundaries, suspense, and transitions.
- Updated status tables in overview and plan pages.
- Fixed stopwatch reset (fn body needs do wrapper for multiple exprs).

Three bugs prevented islands from working during SX wire navigation:
1. components_for_request() only bundled Component and Macro defs, not
Island defs — client never received defisland definitions during
navigation (components_for_page for initial HTML shell was correct).
2. hydrate-island used morph-children which can't transfer addEventListener
event handlers from freshly rendered DOM to existing nodes. Changed to
clear+append so reactive DOM with live signal subscriptions is inserted
directly.
3. asyncRenderToDom (client-side async page eval) checked _component but
not _island on ~-prefixed names — islands fell through to generic eval
which failed. Now delegates to renderDomIsland.
4. setInterval_/setTimeout_ passed SX Lambda objects directly to native
timers. JS coerced them to "[object Object]" and tried to eval as code,
causing "missing ] after element list". Added _wrapSxFn to convert SX
lambdas to JS functions before passing to timers.

- signals.sx: fix has? → has-key?, add def-store/use-store/clear-stores
(L3 named stores), emit-event/on-event/bridge-event (event bridge)
- boot.sx: add sx-hydrate-islands, hydrate-island, dispose-island
for client-side island hydration from SSR output
- bootstrap_js.py: add RENAMES, platform fns (domListen, eventDetail,
domGetData, jsonParse), public API exports for all new functions
- bootstrap_py.py: add RENAMES, server-side no-op stubs for DOM events
- Regenerate sx-ref.js (with boot adapter) and sx_ref.py
- Update reactive-islands status: hydration, stores, bridge all spec'd

- signals.sx: add def-store/use-store/clear-stores (L3 named stores)
and emit-event/on-event/bridge-event (lake→island DOM events)
- reactive-islands.sx: add event bridge, named stores, and plan pages
- Remove ~plan-reactive-islands-content from plans.sx
- Update nav-data.sx and docs.sx routing accordingly

test-signals.sx: 17 tests covering signal basics (create, deref, reset!,
swap!), computed (derive, update, chain), effects (run, re-run, dispose,
cleanup), batch (deferred deduped notifications), and defisland (create,
call, children).
types.py: Island dataclass mirroring Component but for reactive boundaries.
evaluator.py: sf_defisland special form, Island in call dispatch.
run.py: Signal platform primitives (make-signal, tracking context, etc)
and native effect/computed/batch implementations that bridge Lambda
calls across the Python↔SX boundary.
signals.sx: Updated batch to deduplicate subscribers across signals.

New spec file signals.sx defines the signal runtime: signal, computed,
effect, deref, reset!, swap!, batch, dispose, and island scope tracking.
eval.sx: defisland special form + island? type predicate in eval-call.
boundary.sx: signal primitive declarations (Tier 3).
render.sx: defisland in definition-form?.
adapter-dom.sx: render-dom-island with reactive context, reactive-text,
reactive-attr, reactive-fragment, reactive-list helpers.
adapter-html.sx: render-html-island for SSR with data-sx-island/state.
adapter-sx.sx: island? handling in wire format serialization.
special-forms.sx: defisland declaration with docs and example.
