- CLAUDE.md: add SX rendering pipeline overview, service sx/ vs sxc/
convention, dev container mount convention
- docker-compose.dev.yml: add missing ./sx/sx:/app/sx bind mount for
sx_docs (root cause of "Unknown component: ~sx-layout-full")
- async_eval.py: add evaluation modes table to module docstring; log
error when async_eval_slot_to_sx can't find a component instead of
silently falling through to client-side serialization
- helpers.py: remove debug logging from render_to_sx_with_env

The load_service_components call used dirname twice from
sxc/pages/__init__.py, yielding {service}/sxc/ instead of
{service}/. This meant {service}/sx/*.sx files (layouts, calendar
components, etc.) were never loaded into the component env.
- sx: ~sx-layout-full not found → Unknown component on client
- events: ~events-calendar-grid not found → Unknown component
- market: also fix url_for endpoint for defpage_market_admin
(mounted on app, not blueprint — no prefix needed)

When an HTML tag like (div) appears as a kwarg value in SX wire format,
callComponent evaluates it with sxEval (data mode) which doesn't handle
HTML tags. Now sxEval delegates to renderDOM for any render expression
(HTML tags, SVG tags, fragments, raw!, components).

_aser_component expands component bodies in SX wire format mode,
but was evaluating kwarg values with async_eval (HTML mode). This
caused SxExpr kwargs to be fully rendered to HTML strings, which
then broke when serialized back to SX — producing bare symbols
like 'div' that the client couldn't resolve.
Fix: use _aser() for kwarg evaluation to keep values in SX format.

Logs env keys (non-function) when a symbol lookup fails, to help

The JS contains? used `k in c` which throws TypeError on strings.
The Python version silently returned False for strings. Both now
use indexOf/`in` for substring matching on strings.
Fixes: sx.js MOUNT PARSE ERROR on blog index where
(contains? current-local-href "?") was evaluated client-side.

Phase 4 (Test): Update ~test-layout-full and ~test-detail-layout-full defcomps
to use ~root-header with env free variables. Switch render functions to
render_to_sx_with_env.
Phase 5 (Cart): Convert cart-page, cart-admin, and order render functions.
Update cart .sx layout defcomps to use ~root-header from free variables.
Phase 6 (Blog): Convert all 7 blog layouts (blog, settings, sub-settings x5).
Remove all root_header_sx calls from blog.
Phase 7 (Market): Convert market and market-admin layouts plus browse/product
render functions. Remove root_header_sx import.

Nested component calls in _aser are serialized without body expansion,
so free variables inside ~root-header would be sent unresolved to the
client. Fix by making ~root-header/~root-mobile take all values as
&key params, and having parent layout defcomps pass them explicitly.
The parent layout bodies ARE expanded (via async_eval_slot_to_sx),
so their free variables resolve correctly during that expansion.

async_eval_to_sx serializes component calls without expanding their bodies,
so free variables from _ctx_to_env were passed through as unresolved symbols
to the client. Switch to async_eval_slot_to_sx which expands the top-level
component body server-side, resolving free variables during expansion.
Also inline ~root-header/~root-mobile into layout defcomps rather than using
wrapper defcomps (nested ~component calls in _aser are serialized without
expansion, so wrapper defcomps would still leave free vars unresolved).

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).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- 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
leaving italic as an undefined bare symbol.

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.

Without call/cc you get callback pyramids, state machines, command

each a partial ad-hoc reinvention of continuations with its own edge

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.
