Adds optimistic-demo-data, action:add-demo-item, offline-demo-data
to boundary spec. Adds orchestration test spec to in-app test runner
with mocked platform functions.

Add page-render-plan to deps.sx: given page source + env + IO names,
computes a dict mapping each needed component to "server" or "client",
with server/client lists and IO dep collection. 5 new spec tests.
Integration:
- PageDef.render_plan field caches the plan at registration
- compute_page_render_plans() called from auto_mount_pages()
- Client page registry includes :render-plan per page
- Affinity demo page shows per-page render plans

The entire parallel CSS system (StyleValue type, style dictionary,
keyword atom resolver, content-addressed class generation, runtime
CSS injection, localStorage caching) was built but never adopted —
the codebase already uses :class strings with defcomp components
for all styling. Remove ~3,000 lines of unused infrastructure.
Deleted:
- cssx.sx spec module (317 lines)
- style_dict.py (782 lines) and style_resolver.py (254 lines)
- StyleValue type, defkeyframes special form, build-keyframes platform fn
- Style dict JSON delivery (<script type="text/sx-styles">), cookies, localStorage
- css/merge-styles primitives, inject-style-value, fnv1a-hash platform interface
Simplified:
- defstyle now binds any value (string, function) — no StyleValue type needed
- render-attrs no longer special-cases :style StyleValue → class conversion
- Boot sequence skips style dict init step
Preserved:
- tw.css parsing + CSS class delivery (SX-Css headers, <style id="sx-css">)
- All component infrastructure (defcomp, caching, bundling, deps)
- defstyle as a binding form for reusable class strings

Add :affinity :client/:server/:auto annotations to defcomp, with
render-target function combining affinity + IO analysis. Includes
spec (eval.sx, deps.sx), tests, Python evaluator, and demo page.
Fix critical bug: Python SX parser _ESCAPE_MAP was missing \r and \0,
causing bootstrapped JS parser to treat 'r' as whitespace — breaking
all client-side SX parsing. Also add \0 to JS string emitter and
fix serializer round-tripping for \r and \0.
Reserved word escaping: bootstrappers now auto-append _ to identifiers
colliding with JS/Python reserved words (e.g. default → default_,
final → final_), so the spec never needs to avoid host language keywords.

Server streams HTML shell with ~suspense placeholders immediately,
then sends resolution <script> chunks as async IO completes. Browser
renders loading skeletons instantly, replacing them with real content
as data arrives via __sxResolve().
- defpage :stream true opts pages into streaming response
- ~suspense component renders fallback with data-suspense attr
- resolve-suspense in boot.sx (spec) + bootstrapped to sx-browser.js
- __sxPending queue handles resolution before sx-browser.js loads
- execute_page_streaming() async generator with concurrent IO tasks
- Streaming demo page at /isomorphism/streaming with 1.5s simulated delay

read-spec-file is a server-only page helper. When the client router
tried to evaluate :content, it couldn't find the function. Move all
file reads into the :data expression (evaluated server-side) so
:content only references data bindings.

New /testing/ section with 6 pages: overview (all specs), evaluator,
parser, router, renderer, and runners. Each page runs tests server-side
(Python) and offers a browser "Run tests" button (JS). Modular browser
runner (sxRunModularTests) loads framework + per-spec sources from DOM.

Python evaluator runs test.sx at page load, results shown alongside
the browser runner. Both hosts prove the same 81 tests from the same
spec file — server on render, client on click.

Spec layer (orchestration.sx):
- try-client-route now handles :data pages instead of falling back to server
- New abstract primitive resolve-page-data(name, params, callback) — platform
decides transport (HTTP, IPC, cache, etc)
- Extracted swap-rendered-content and resolve-route-target helpers
Platform layer (bootstrap_js.py):
- resolvePageData() browser implementation: fetches /sx/data/<name>, parses
SX response, calls callback. Other hosts provide their own transport.
Server layer (pages.py):
- evaluate_page_data() evaluates :data expr, serializes result as SX
- auto_mount_page_data() mounts /sx/data/ endpoint with per-page auth
- _build_pages_sx now computes component deps for all pages (not just pure)
Test page at /isomorphism/data-test exercises the full pipeline.

Three levels of ../ overshot from /app/sxc/pages/ to /. Use same
two-level pattern with /app/shared fallback as _read_spec_file.

Click a page row to expand its component bundle tree. Each component
shows pure/IO badge, IO refs, dep count. Click a component to expand
its full defcomp SX source. Uses <details>/<summary> for zero-JS
expand/collapse.

Extend the spec with IO scanning functions (scan-io-refs, transitive-io-refs,
compute-all-io-refs, component-pure?) that detect IO primitive references in
component ASTs. Components are classified as pure (no IO deps, safe for client
rendering) or IO-dependent (must expand server-side).
The partial evaluator (_aser) now uses per-component IO metadata instead of
the global _expand_components toggle: IO-dependent components expand server-
side, pure components serialize for client. Layout slot context still expands
all components for backwards compat.
Spec: 5 new functions + 2 platform interface additions in deps.sx
Host: io_refs field + is_pure property on Component, compute_all_io_refs()
Bootstrap: both sx_ref.py and sx-ref.js updated with IO functions
Bundle analyzer: shows pure/IO classification per page

Demonstrates Phase 1 dep analysis in action: computes per-page component
bundles for all sx-docs pages using the deps.sx transitive closure
algorithm, showing needed vs total components with visual progress bars.
- New page at /plans/bundle-analyzer with Python data helper
- New components: ~bundle-analyzer-content, ~analyzer-stat, ~analyzer-row
- Linked from Phase 1 section and Plans nav
- Added sx/sx/ to tailwind content paths

Parses special-forms.sx spec into categorized form cards with syntax,
description, tail-position info, and highlighted examples. Follows the
same pattern as the Primitives page: Python helper returns structured
data, .sx components render it.

Add boundary.sx declaring all 34 I/O primitives, 32 page helpers, and 9
allowed boundary types. Runtime validation in boundary.py checks every
registration against the spec — undeclared primitives/helpers crash at
startup with SX_BOUNDARY_STRICT=1 (now set in both dev and prod).
Key changes:
- Move 5 I/O-in-disguise primitives (app-url, asset-url, config,
jinja-global, relations-from) from primitives.py to primitives_io.py
- Remove duplicate url-for/route-prefix from primitives.py (already in IO)
- Fix parse-datetime to return ISO string instead of raw datetime
- Add datetime→isoformat conversion in _convert_result at the edge
- Wrap page helper return values with boundary type validation
- Replace all SxExpr(f"...") patterns with sx_call() or _sx_fragment()
- Add assert declaration to primitives.sx

- New Bootstrappers top-level section with overview index and JS bootstrapper
page that runs bootstrap_js.py and displays both source and generated output
with live script injection (full page load, not SX navigation)
- Essays section: index page with linked cards and summaries, sx-sucks moved
to end of nav, removed "grand tradition" line
- Specs: English prose descriptions alongside all canonical .sx specs, added
Boot/CSSX/Browser spec files to architecture page
- Layout: menu bar nav items wrap instead of overflow, baseline alignment
between label and nav options
- Homepage: added copyright line

Spec file registry (slugs, filenames, titles, descriptions) now lives in
nav-data.sx as SX data definitions. Python helper reduced to pure file I/O
(read-spec-file). Architecture page updated with engine/orchestration split
and dependency graph.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add Architecture intro page explaining the spec's two-layer design
(core language + selectable adapters) with dependency graph
- Split specs into Core (parser, eval, primitives, render) and
Adapters (DOM, HTML, SX wire, SxEngine) overview pages
- Add individual detail pages for all adapter and engine specs
- Update nav with Architecture landing, Core, Adapters, and all
individual spec file links

- Fix highlight() returning SxExpr so syntax-highlighted code renders
as DOM elements instead of leaking SX source text into the page
- Add Specs section that reads and displays canonical SX spec files
from shared/sx/ref/ with syntax highlighting
- Add "The Reflexive Web" essay on SX becoming a complete LISP with
AI as native participant
- Change logo from (<x>) to (<sx>) everywhere
- Unify all backgrounds to bg-stone-100, center code blocks
- Skip component/style cookie cache in dev mode so .sx edits are
visible immediately on refresh without clearing localStorage

Nav data, section nav, example content, reference table builders, and
all slug dispatch now live in .sx files. Python helpers reduced to
data-only returns (highlight, primitives-data, reference-data,
attr-detail-data). Deleted essays.py and utils.py entirely.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Events: route imports now point to specific sub-modules (entries,
tickets, slots) instead of all going through renders.py. Merged
layouts into helpers.py. __init__.py now 20 lines.
SX Docs: moved dispatchers from helpers.py into essays.py, cleaned
up __init__.py to 24 lines.
