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.

Component names now reflect filesystem location using / as path separator
and : as namespace separator for shared components:
~sx-header → ~layouts/header
~layout-app-body → ~shared:layout/app-body
~blog-admin-dashboard → ~admin/dashboard
209 files, 4,941 replacements across all services.

All routes moved under /sx/ prefix:
- / redirects to /sx/
- /sx/ serves home page
- /sx/<path:expr> is the catch-all for SX expression URLs
- Bare /(...) and /~... redirect to /sx/(...) and /sx/~...
- All ~600 hrefs, sx-get attrs, defhandler paths, redirect
targets, and blueprint routes updated across 44 files
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Update ~sx-doc :path values in docs.sx from old-style paths to SX
expression URLs (fixes client-side rendered page nav resolution)
- Fix stale hrefs in content/pages.py code examples
- Fix tabs push-url in examples.sx
- Add self-defining-medium + sx-urls + sx-protocol to essay/plan cases

The <slug> route param doesn't match slashes, so
/language/specs/explore/<slug> needs its own defpage
instead of being handled inside specs-page.

The helper was trying to look up all-spec-items from get_component_env(),
but that only contains defcomp/defmacro — not regular defines. Now the
SX routing layer calls find-spec and passes filename/title/desc directly.
Also adds boundary declaration for spec-explorer-data.

- _spec_explorer_data() helper: parses spec files into sections, defines,
effects, params, source blocks, and Python translations via PyEmitter
- specs-explorer.sx: 10 defcomp components for explorer UI — cards with
effect badges, typed param lists, collapsible SX/Python translation panels
- Route at /language/specs/explore/<slug> via docs.sx
- "Explore" link on existing spec detail pages

New plan page at /etc/plans/spec-explorer describing the "fifth ring"
architecture: SX exploring itself through per-function cards showing
source, Python/JS/Z3 translations, platform deps, tests, proofs, and
usage examples.

Specs nav reorganized from flat list into 6 sections with children:
Core (5), Adapters (4), Browser (4), Reactive (1), Host Interface (3),
Extensions (4). Added missing spec items: adapter-async, signals,
boundary, forms, page-helpers, types. Architecture page updated to
match. New essay on ars, techne, and the self-making artifact chain.

New hierarchy: Geography (Reactive Islands, Hypermedia Lakes, Marshes,
Isomorphism), Language (Docs, Specs, Bootstrappers, Testing),
Applications (CSSX, Protocols), Etc (Essays, Philosophy, Plans).
All routes updated to match: /reactive/* → /geography/reactive/*,
/docs/* → /language/docs/*, /essays/* → /etc/essays/*, etc.
Updates nav-data.sx, all defpage routes, API endpoints, internal links
across 43 files. Enhanced find-nav-match for nested group resolution.
Also includes: page-helpers-demo sf-total fix (reduce instead of set!),
rebootstrapped sx-browser.js and sx_ref.py, defensive slice/rest guards.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add page-helpers-demo page with defisland ~demo-client-runner (pure SX,
zero JS files) showing spec functions running on both server and client
- Fix _aser_component children serialization: flatten list results from map
instead of serialize(list) which wraps in parens creating ((div ...) ...)
that re-parses as invalid function call. Fixed in adapter-async.sx spec
and async_eval_ref.py
- Switch _eval_slot to use async_eval_ref.py when SX_USE_REF=1 (was
hardcoded to async_eval.py)
- Add Island type support to async_eval_ref.py: import, SSR rendering,
aser dispatch, thread-first, defisland in _ASER_FORMS
- Add server affinity check: components with :affinity :server expand
even when _expand_components is False
- Add diagnostic _aser_stack context to EvalError messages
- New spec files: adapter-async.sx, page-helpers.sx, platform_js.py
- Bootstrappers: page-helpers module support, performance.now() timing
- 0-arity lambda event handler fix in adapter-dom.sx

- Rename /reactive-islands/ → /reactive/, /reference/ → /hypermedia/reference/,
/examples/ → /hypermedia/examples/ across all .sx and .py files
- Add 404 error page (not-found.sx) working on both server refresh and
client-side SX navigation via orchestration.sx error response handling
- Add trailing slash redirect (GET only, excludes /api/, /static/, /internal/)
- Remove blue sky-500 header bar from SX docs layout (conditional on header-rows)
- Fix 405 on API endpoints from trailing slash redirect hitting POST/PUT/DELETE
- Fix client-side 404: orchestration.sx now swaps error response content
instead of silently dropping it
- Add new plan files and home page component

Client-rendered islands were re-hydrated by boot.sx because
renderDomIsland didn't mark them as processed. Hydration read
empty data-sx-state, overwriting kwargs (e.g. path) with NIL.
Fix: mark-processed! in adapter-dom.sx so boot skips them.
New plan: marshes — where reactivity and hypermedia interpenetrate.
Three patterns: server writes to signals, reactive marsh zones with
transforms, and signal-bound hypermedia interpretation.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Islands survive hypermedia swaps: morph-node skips hydrated
data-sx-island elements when the same island exists in new content.
dispose-islands-in skips hydrated islands to prevent premature cleanup.
- @client directive: .sx files marked ;; @client send define forms to browser
- CSSX client-side: cssxgroup renamed (no hyphen) to avoid isRenderExpr
matching it as a custom element — was producing [object HTMLElement]
- Island wrappers: div→span to avoid block-in-inline HTML parse breakage
- ~sx-header is now a defisland with inline reactive colour cycling
- bootstrap_js.py defaults output to shared/static/scripts/sx-browser.js
- Deleted stale sx-ref.js (sx-browser.js is the canonical browser build)
- Hegelian Synthesis essay: dialectic of hypertext and reactivity
- component-source helper handles Island types for docs pretty-printing

Documents the self-hosting process for js.sx including the G0 bug
where Python's `if fn_expr` treated 0/False/"" as falsy, emitting
NIL instead of the correct value. Adds live verification page,
translation differences table, and nav entry.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Update plan page with completion status and results
- Add ~bootstrapper-self-hosting-content component with live G0/G1 verification
- Add _self_hosting_data() helper: loads py.sx, runs it, diffs against G0
- Add "Self-Hosting (py.sx)" to bootstrappers nav and index table
- Wire /bootstrappers/self-hosting route

js.sx — SX-to-JavaScript translator + ahead-of-time component compiler.
Two modes: spec bootstrapper (replacing bootstrap_js.py) and component
compiler (server-evaluated SX trees → standalone JS DOM construction).

Plan for py.sx — an SX-to-Python translator written in SX that
replaces bootstrap_py.py. Covers translation rules, statement vs
expression modes, mutation/cell variables, five implementation
phases, fixed-point verification, and implications for multi-host
bootstrapping.

Lambda multi-body fix: sf-lambda used (nth args 1), dropping all but the first
body expression. Fixed to collect all body expressions and wrap in (begin ...).
This was foundational — every multi-expression lambda in every island silently
dropped expressions after the first.
Reactive islands: fix dom-parent marker timing (first effect run before marker
is in DOM), fix :key eager evaluation, fix error boundary scope isolation,
fix resource/suspense reactive cond tracking, fix inc not available as JS var.
New essay: "React is Hypermedia" — argues that reactive islands are hypermedia
controls whose behavior is specified in SX, not a departure from hypermedia.

- 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).

New top-level Philosophy section in sx-docs. Moved SX Manifesto and Strange
Loops from Essays, added three new essays: SX and Wittgenstein (language games,
limits of language, fly-bottles), SX and Dennett (real patterns, multiple drafts,
intentional stance), and S-Existentialism (existence precedes essence, bad faith,
the absurd). Updated all cross-references and navigation.

- 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
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- New nav entry in ~sx-main-nav (layouts.sx)
- Nav items: Overview, Demo, Plan link (nav-data.sx)
- Overview page: architecture quadrant, four levels, signal primitives,
island lifecycle, implementation status table with done/todo
- Demo page: annotated code examples for signal+computed+effect, batch,
cleanup, computed chains, defisland, test suite
- defpage routes: /reactive-islands/ and /reactive-islands/<slug>

New essay arguing SX eliminates the entire conventional web toolchain
(bundlers, transpilers, package managers, CSS tools, dev servers, linters,
type checkers, framework CLIs) and that agentic AI replaces the code editor
itself. Links Carson Gross's "Yes, and..." essay with a Zen Buddhism framing
of the write→read→describe progression.

Moved on-demand CSS delivery protocol from docs/css into /cssx/delivery,
framed as one strategy among several. Removed the CSSX Components plan
(now redundant with the top-level /cssx/ section).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New top-level section in sx-docs: /cssx/ with 6 pages:
- Overview: the idea, what changed, advantages
- Patterns: class mapping, data-driven, style functions, responsive, emitting CSS
- Async CSS: components that fetch/cache CSS before rendering via ~suspense
- Live Styles: SSE/WS examples for real-time style updates (noted as future)
- Comparisons: vs styled-components, CSS Modules, Tailwind, Vanilla Extract
- Philosophy: proof by deletion, the right abstraction level
Also:
- Remove CSSX from specs nav (spec file deleted)
- Fix renderer spec prose (no longer mentions StyleValue)
- Update On-Demand CSS essay summary
- Mark CSSX Components plan as done

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.

Replace the existing CSSX plan with a component-based approach where styling
is handled by regular defcomp components that apply classes, respond to data,
and compose naturally — eliminating opaque hash-based class names.

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

Pipeline definitions as .sx files evaluated by a minimal Python runner.
CI primitives (shell-run, docker-build, git-diff-files) are boundary-declared
IO, only available to the runner. Steps are defcomp components composable
by nesting. Fixes pre-existing unclosed parens in isomorphic roadmap section.
