Phase 0: Add _ctx_to_env() and render_to_sx_with_env() to shared/sx/helpers.py,
register_sx_layout() to shared/sx/layouts.py, and ~root-header/~root-mobile
wrapper defcomps to layout.sx. Convert built-in "root" layout to .sx.
Phases 1-3: Convert account (65→19 lines), federation (105→97 lines),
and orders (88→21 lines) to use register_sx_layout with .sx defcomps
that read ctx values as free variables from the evaluation environment.
No more Python building SX strings via SxExpr(await root_header_sx(ctx)).

(filter (feTurbulence ...)) inside (svg ...) has no keyword first arg,
so the keyword-only check dispatched it as a HO function. Now also
check SVG/MathML context (ns in client, _svg_context in server).

Hyphenated names like app-url are variables, not custom elements.
Only treat as custom element when first arg is a Keyword (tag call pattern).

- Fix filter/map dispatching as HO functions when used as SVG/HTML tags
(peek at first arg — Keyword means tag call, not function call)
- Add html: prefix escape hatch to force any name to render as an element
- Support custom elements (hyphenated names) per Web Components spec
- SVG/MathML namespace auto-detection: client threads ns param through
render chain; server uses _svg_context ContextVar so unknown tags
inside (svg ...) or (math ...) render as elements without enumeration

Soviet constructivist poster with paper texture filters, grid lines,

feComponentTransfer, feFuncR/G/B/A, feDisplacementMap, feComposite,
feFlood, feImage, feMorphology, feSpecularLighting, feDiffuseLighting,
fePointLight, feSpotLight, feDistantLight.

SX is a paradigm, not a language. Changed 7 instances where "language"
referred to SX itself: "one paradigm since 1958", "the paradigm is the
framework", "not a framework but a paradigm", "paradigms do not have
breaking changes", "the paradigm itself provides", "a paradigm that
does not require a migration guide", "distinct from the paradigm".

The (code :class "text-violet-700" ...) was embedded inside a string
child of (p), causing the SX parser to see text-violet-700 as a bare
symbol. Close the text string before the (code) element so it becomes
a proper child of the paragraph.

The em span variable was embedded inside an unclosed sx string,
causing the " before "italic" to close the outer string and

Implement missing SxEngine features:
- SSE (sx-sse, sx-sse-swap) with EventSource management and auto-cleanup
- Response headers: SX-Trigger, SX-Retarget, SX-Reswap, SX-Redirect,
SX-Refresh, SX-Location, SX-Replace-Url, SX-Trigger-After-Swap/Settle
- View Transitions API: transition:true swap modifier + global config
- every:<time> trigger for polling (setInterval)
- sx-replace-url (replaceState instead of pushState)
- sx-disabled-elt (disable elements during request)
- sx-prompt (window.prompt, value sent as SX-Prompt header)
- sx-params (filter form parameters: *, none, not x,y, x,y)
Adds docs (ATTR_DETAILS, BEHAVIOR_ATTRS, headers, events), demo
components in reference.sx, API endpoints (prompt-echo, sse-time),
and 27 new unit tests for engine logic.

Phase 7 of the zero-Python-rendering plan. All 100 rendering functions
move from events/sx/sx_components.py into events/sxc/pages/__init__.py.
Route handlers (15 files) import from sxc.pages instead.
load_service_components call moves into _load_events_page_files.

Add sx-preserve/sx-ignore (morph skip), sx-indicator (loading element),
sx-validate (form validation), sx-boost (progressive enhancement),

SX_UNIQUE_ATTRS with full ATTR_DETAILS docs and reference.sx demos.

Without call/cc you get callback pyramids, state machines, command
pattern undo stacks, Promise chains, and framework-specific hooks —
each a partial ad-hoc reinvention of continuations with its own edge
cases. The complexity doesn't disappear; it moves into user code.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Covers server-side (suspendable rendering, streaming, error boundaries),
client-side (linear async flows, wizard forms, cooperative scheduling,
undo), and implementation path from the existing TCO trampoline. Updates
TCO essay's continuations section to link to the new essay instead of
dismissing the idea. Fixes "What sx is not" to acknowledge macros + TCO.

Evaluator: add _Thunk + _trampoline for tail-call optimization in

query_registry.py unwrap thunks at non-tail positions.

A satirical essay in the style of The Communist Manifesto, recasting
the historic struggle between bourgeoisie and proletariat as the war
between HTML, JS, and CSS — with frameworks as petty-bourgeois lackeys
and s-expressions as the revolutionary force that abolishes the
language distinction itself.

Cover @keyframes (defkeyframes special form + built-in animations),
@container queries, dynamic atom construction (no server round-trip

Document the design for native s-expression style primitives

The service registry uses __getattr__, so .get() is interpreted

Move remaining 19 rendering functions from the 2487-line
sx_components.py to their direct callers:
- menu_items/routes.py: menu item form, page search, nav OOB
- post/admin/routes.py: calendar view, associated entries, nav OOB
- sxc/pages/__init__.py: editor panel, post data inspector, preview,
entries browser, settings form, edit page editor
- bp/blog/routes.py: inline new post page composition
Move load_service_components() call from sx_components module-level
to setup_blog_pages() so .sx files still load at startup.

The old sx_components.py used os.path.dirname(__file__) to resolve
the app root. When it was deleted, the replacement call in app.py
used the string "cart" which resolves to /app/cart/ (alembic only),
not /app/ where the sx/ directory lives. Use Path(__file__).parent.

The sentinel was written to shared/_reload_sentinel.py but shared/ is

Use dto_to_dict() from shared/contracts/dtos.py for dataclass
serialization instead of raw dataclasses.asdict(). This ensures
datetimes are converted to ISO format strings (not RFC 2822 from
jsonify), matching what dto_from_dict() expects on the receiving end.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The defquery conversion routes inter-service results through
_dto_to_dict which checked __dict__ (absent on slots dataclasses),
producing {"value": obj} instead of proper field dicts. This broke
TicketDTO deserialization in the cart app. Check __dataclass_fields__
first and use dataclasses.asdict() for correct serialization.

The inter-service data layer (fetch_data/call_action) was the least
structured part of the codebase — Python _handlers dicts with ad-hoc
param extraction scattered across 16 route files. This replaces them
with declarative .sx query/action definitions that make the entire
inter-service protocol self-describing and greppable.
Infrastructure:
- defquery/defaction special forms in the sx evaluator
- Query/action registry with load, lookup, and schema introspection
- Query executor using async_eval with I/O primitives
- Blueprint factories (create_data_blueprint/create_action_blueprint)
with sx-first dispatch and Python fallback
- /internal/schema endpoint on every service
- parse-datetime and split-ids primitives for type coercion
Service extractions:
- LikesService (toggle, is_liked, liked_slugs, liked_ids)
- PageConfigService (ensure, get_by_container, get_by_id, get_batch, update)
- RelationsService (wraps module-level functions)
- AccountDataService (user_by_email, newsletters)
- CartItemsService, MarketDataService (raw SQLAlchemy lookups)
50 of 54 handlers converted to sx, 4 Python fallbacks remain
(ghost-sync/push-member, clear-cart-for-order, create-order).
Net: -1,383 lines Python, +251 lines modified.

Convert 6 blog settings pages (settings-home, cache, snippets, menu-items,
tag-groups, tag-group-edit) from Python page helpers to .sx defpages with
(service "blog-page" ...) IO primitives. Create data-driven defcomps that
handle iteration via (map ...) instead of Python loops.
Post-related page helpers (editor, post-admin/data/preview/entries/settings/edit)
remain as Python helpers — they depend on _ensure_post_data and sx_components
rendering functions that need separate conversion.
