test-cek-reactive.sx: 9 tests across 4 suites — deref pass-through,
signal without reactive-reset, reactive-reset shift with continuation
capture, scope disposal cleanup. run_cek_reactive_tests.py: new runner
loading signals+frames+cek. Both test runners override sx_ref.eval_expr
back to tree-walk so interpreted .sx uses tree-walk internally.
Plan page added to sx-docs.

frames.sx: ReactiveResetFrame + DerefFrame constructors,
kont-capture-to-reactive-reset, has-reactive-reset-frame?.
cek.sx: deref as CEK special form, step-sf-deref pushes DerefFrame,
reactive-shift-deref captures continuation as signal subscriber,
ReactiveResetFrame in step-continue calls update-fn on re-render.
adapter-dom.sx: cek-reactive-text/cek-reactive-attr using cek-run
with ReactiveResetFrame for implicit DOM bindings.

SPEC_MODULES + SPEC_MODULE_ORDER for frames/cek in platform_js.py,
PLATFORM_CEK_JS + CEK_FIXUPS_JS constants, auto-inclusion in
run_js_sx.py, 70+ RENAMES in js.sx. Python: CEK always-include in
bootstrap_py.py, eval_expr/trampoline overridden to cek_run in
platform_py.py with _tree_walk_* preserved for test runners.

Replace _Signal class (Python) and SxSignal constructor (JS) with plain
dicts keyed by "__signal". Nine platform accessor functions become ~20
lines of pure SX in signals.sx. type-of returns "dict" for signals;
signal? is now a structural predicate (dict? + has-key?).
Net: -168 lines platform, +120 lines SX. Zero platform primitives for
reactivity — signals compile to any host via the bootstrappers.

Reactive tracking (deref/computed/effect dep discovery) and island lifecycle
now use the general scoped effects system instead of parallel infrastructure.
Two scope names: "sx-reactive" for tracking context, "sx-island-scope" for
island disposable collection. Eliminates ~98 net lines: _TrackingContext class,
7 tracking context platform functions (Python + JS), *island-scope* global,
and corresponding RENAME_MAP entries. All 20 signal tests pass (17 original +
3 new scope integration tests), plus CEK/continuation/type tests clean.

- Add `scope` special form to eval.sx: (scope name body...) or
(scope name :value v body...) — general dynamic scope primitive
- `provide` becomes sugar: (provide name value body...) calls scope
- Rename provide-push!/provide-pop! to scope-push!/scope-pop! throughout
all adapters (async, dom, html, sx) and platform implementations
- Update boundary.sx: Tier 5 now "Scoped effects" with scope-push!/
scope-pop! as primary, provide-push!/provide-pop! as aliases
- Add scope form handling to async adapter and aser wire format
- Update sx-browser.js, sx_ref.py (bootstrapped output)
- Add scopes.sx docs page, update provide/spreads/demo docs
- Update nav-data, page-functions, docs page definitions

Rename to .sx.future — the file uses #z3 reader macros that aren't
implemented yet, causing a ParseError that blocks ALL component loading
and breaks the provide docs page.

Lead with provide/emit! from the first sentence. make-spread/spread?/spread-attrs
are now presented as user-facing API on top of the provide/emit! substrate,
not as independent primitives. Restructured sections, removed redundant
"deeper primitive" content that duplicated the new section I.

- New geography article (provide.sx): four primitives, demos, nested scoping,
adapter comparison, spec explorer links
- Updated spreads article section VI: provide/emit! is now implemented, not planned
- Fixed foundations.sx: ~docs/code-block → ~docs/code (undefined component
was causing the page to silently fail to render)
- Added nav entry and defpage route for provide/emit! article

CI was doing git reset --hard on /root/rose-ash (the dev directory),
flipping the checked-out branch and causing empty diffs when merging.
Now builds in /root/rose-ash-ci and uses push event SHAs for diffing.
Also adds --resolve-image always to stack deploys.

Spreads now emit their attrs into the nearest element's provide scope
instead of requiring per-child spread? checks at every intermediate
layer. emit! is tolerant (no-op when no provider), so spreads in
non-element contexts silently vanish.
- adapter-html: element/lake/marsh wrap children in provide, collect
emitted; removed 14 spread filters from fragment, forms, components
- adapter-sx: aser wraps result to catch spread values from fn calls;
aser-call uses provide with attr-parts/child-parts ordering
- adapter-async: same pattern for both render and aser paths
- adapter-dom: added emit! in spread dispatch + provide in element
rendering; kept spread? checks for reactive/island and DOM safety
- platform: emit! returns NIL when no provider instead of erroring
- 3 new aser tests: stored spread, nested element, silent drop

Spread values from make-spread were crashing the wire format serializer:
- serialize() had no "spread" case, fell through to (str val) producing
Python repr "<shared.sx.ref.sx_ref._Spread...>" which was treated as
an undefined symbol
- aser-call/async-aser-call didn't handle spread children — now merges
spread attrs as keyword args into the parent element
- aser-fragment/async-aser-fragment didn't filter spreads — now filters
them (fragments have no parent element to merge into)
- serialize() now handles spread type: (make-spread {:key "val"})
Added 3 aser-spreads tests. All 562 tests pass.

The plans were routed in page-functions.sx (GraphSX URL eval) but
missing from the defpage case in docs.sx (server-side slug route).

- Add \uXXXX unicode escape support to parser.py and parser.sx spec
- Add char-from-code primitive (Python chr(), JS String.fromCharCode())
- Fix variadic infix operators in both bootstrappers (js.sx, py.sx) —
(+ a b c d) was silently dropping terms, now left-folds correctly
- Rebootstrap sx_ref.py and sx-browser.js with all fixes
- Fix 3 pre-existing map-dict test failures in shared/sx/tests/run.py
- Add live demos alongside examples in spreads essay (side-by-side layout)
- Add scoped-effects plan: algebraic effects as unified foundation for
spread/collect/island/lake/signal/context
- Add foundations plan: CEK machine, the computational floor, three-axis
model (depth/topology/linearity), Curry-Howard correspondence
- Route both plans in page-functions.sx and nav-data.sx

SX parser doesn't process \u escapes — they render as literal text.
Use actual UTF-8 characters (→, —, £, ⬡) directly in source.

(code "...") is an HTML tag — works in render context but not inside
(list ...) which fully evaluates args. Use plain strings in table rows.

Without this, /sx/(geography.(spreads)) 404s because spreads isn't
defined as a page function to return the content component.

Documents the three orthogonal primitives (spread, collect!, reactive-spread),
their operation across server/client/morph boundaries, CSSX as use case,
semantic style variables, and the planned provide/context/emit! unification.

When a spread value (e.g. from ~cssx/tw) appears inside an island with
signal-dependent tokens, reactive-spread tracks deps and updates the
element's class/attrs when signals change. Old classes are surgically
removed, new ones appended, and freshly collected CSS rules are flushed
to the live stylesheet. Multiple reactive spreads on one element are safe.

adapter-dom.sx: if/when/cond reactive paths now check whether
initial-result is a spread. If so, return it directly — spreads
aren't DOM nodes and can't be appended to fragments. This lets
any spread-returning component (like ~cssx/tw) work inside islands
without the spread being silently dropped.
cssx.sx: revert make-spread workaround — the root cause is now
fixed in the adapter. ~cssx/tw can use a natural top-level if.

Component params are bound from kwargs only in render-dom-component.
Positional args go to children, so (~ cssx/tw "...") binds tokens=nil.
The :tokens keyword is required: (~cssx/tw :tokens "...").

layouts.sx: change all (~ cssx/tw :tokens "...") to (~cssx/tw "...")
matching the documented positional calling convention.
Move (~cssx/flush) after children so page content rules are also
collected before the server-side <style data-cssx> flush.

deps.sx: scan island bodies for component deps (was only scanning
"component" and "macro", missing "island" type). This ensures
~cssx/tw and its dependencies are sent to the client for islands.
cssx.sx: move if inside make-spread arg so it's evaluated by
eval-expr (no reactive wrapping) instead of render-to-dom which
applies reactive-if inside island scope, converting the spread
into a fragment and losing the class attrs.
Added island dep tests at 3 levels: test-deps.sx (spec),
test_deps.py (Python), test_parity.py (ref vs fallback).
sx-browser.js: temporary debug logging at spread detection points.

Islands render independently on the client, so ~cssx/tw calls
collect!("cssx", rule) but no ~cssx/flush runs. Add flush-cssx-to-dom
in boot.sx that injects collected rules into a persistent <style>
element in <head>.
Called at all lifecycle points: boot-init, sx-mount, resolve-suspense,
post-swap (navigation morph), and swap-rendered-content (client routes).

The previous fix only guarded domAppend/domInsertAfter, but many
platform JS functions (asyncRenderChildren, asyncRenderElement,
asyncRenderMap, render, sxRenderWithEnv) call appendChild directly.
Add _spread guards to all direct appendChild sites. For async element
rendering, merge spread attrs onto parent (class/style join, others
overwrite) matching the sync adapter behavior.

Spread values (from ~cssx/tw etc.) are attribute dicts, not DOM nodes.
When they appear in non-element contexts (fragments, islands, lakes,
reactive branches), they must not be passed to appendChild/insertBefore.
Add _spread guard to platform domAppend and domInsertAfter — fixes
TypeError: Node.appendChild: Argument 1 does not implement interface Node.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Spread values returned by components like ~cssx/tw are not DOM nodes
and cannot be passed to appendChild. Filter them in fragment, let,
begin/do, component children, and data list rendering paths — matching
the HTML adapter's existing spread filtering.
