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.

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)

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.

The .sx component files (home.sx, docs.sx, etc.) live in sxc/, but
the path was pointing to sxc/pages/ after the move from sx_components.py.

These are sx implementations of htmx attributes (boost, preload,
preserve, indicator, validate, ignore, optimistic), not unique to sx.

Consolidate 86 component rendering functions into sxc/pages/__init__.py,
update 37 import sites in routes.py, remove app.py side-effect imports,
and delete sx/sxc/sx_components.py.

Add sx-preserve/sx-ignore (morph skip), sx-indicator (loading element),
sx-validate (form validation), sx-boost (progressive enhancement),
sx-preload (hover prefetch with 30s cache), and sx-optimistic (instant
UI preview with rollback). Move all from HTMX_MISSING_ATTRS to
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.

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
lambdas, components, if/when/cond/case/let/begin. All callers in
html.py, resolver.py, handlers.py, pages.py, jinja_bridge.py, and
query_registry.py unwrap thunks at non-tail positions.
SX docs: update tagline to "s-expressions for the web", rewrite intro
to reflect that SX replaces most JavaScript need, fix "What sx is not"
to acknowledge macros and TCO exist.

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.

Python no longer generates s-expression strings. All SX rendering now
goes through render_to_sx() which builds AST from native Python values
and evaluates via async_eval_to_sx() — no SX string literals in Python.
- Add render_to_sx()/render_to_html() infrastructure in shared/sx/helpers.py
- Add (abort status msg) IO primitive in shared/sx/primitives_io.py
- Convert all 9 services: ~650 sx_call() invocations replaced
- Convert shared helpers (root_header_sx, full_page_sx, etc.) to async
- Fix likes service import bug (likes.models → models)

Defpages are now declared with absolute paths in .sx files and auto-mounted
directly on the Quart app, removing ~850 lines of blueprint mount_pages calls,
before_request hooks, and g.* wrapper boilerplate. A new page = one defpage
declaration, nothing else.
Infrastructure:
- async_eval awaits coroutine results from callable dispatch
- auto_mount_pages() mounts all registered defpages on the app
- g._defpage_ctx pattern passes helper data to layout context
Migrated: sx, account, orders, federation, cart, market, events, blog

Per-attribute documentation pages at /reference/attributes/<slug> with:
- Live interactive demos (demo components in reference.sx)
- S-expression source code display
- Server handler code shown as s-expressions (defhandlers in handlers/reference.sx)
- Wire response display via OOB swaps on demo interaction
- Linked attribute names in the reference table
Covers all 20 implemented attributes (sx-get/post/put/delete/patch,
sx-trigger/target/swap/swap-oob/select/confirm/push-url/sync/encoding/
headers/include/vals/media/disable/on:*, sx-retry, data-sx, data-sx-env).
Also adds sx-on:* to BEHAVIOR_ATTRS, updates REFERENCE_NAV to link
/reference/attributes, and makes /reference/ an index page.

Replace Python GET page handlers with declarative defpage definitions in .sx
files across all 8 apps (sx docs, orders, account, market, cart, federation,
events, blog). Each app now has sxc/pages/ with setup functions, layout
registrations, page helpers, and .sx defpage declarations.
Core infrastructure: add g I/O primitive, PageDef support for auth/layout/
data/content/filter/aside/menu slots, post_author auth level, and custom
layout registration. Remove ~1400 lines of render_*_page/render_*_oob
boilerplate. Update all endpoint references in routes, sx_components, and
templates to defpage_* naming.

- Add sx_content to _post_to_edit_dict so edit page receives existing content
- Add SX/Koenig editor tabs, sx-editor mount point, and SxEditor.mount init
- Only pass sx_content to writer_update when form field is present (prevents
accidental clearing when editing via Koenig-only path)
- Add csrf_exempt to example API POST/DELETE/PUT demo endpoints
- Add defpage infrastructure (pages.py, layouts.py) and sx docs page definitions
- Add defhandler definitions for example API handlers (examples.sx)

The ~value-options component wrapped options in a fragment that didn't
render correctly inside a <select> innerHTML swap. Return plain
(option) elements directly.

- Move .sx-fade-in and .sx-loading-btn CSS from inline (style) tags to
basics.css so they go through the on-demand CSS registry
- Pretty-print sx source in wire response display (not all on one line)
- Change sx logo from </> icon to (</>) text
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- All 6 examples show Component and Wire response as placeholders that
fill with actual content when the demo is triggered (via OOB swaps)
- Wire response shows full wire content including component definitions
(when not cached) and CSS style block
- Component display only includes defs the client doesn't already have,
matching real sx_response() behaviour
- Add "Clear component cache" button to reset localStorage + in-memory
component env so next interaction shows component download
- Rebuild tw.css with Tailwind v3.4.19 including sx content paths
- Optimize sx_response() CSS scanning to only scan sent comp_defs

highlight.py handles syntax coloring with Tailwind classes —
Prism classes were conflicting and are not needed.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Pass :code keyword to ~doc-code and ~example-source components
(highlighted content was positional but components use &key code)
- Rebuild tw.css (v3.4.19) with sx/sxc and sx/content in content paths
so highlight.py classes (text-violet-600, text-rose-600, etc.) are included
- Add bg-violet-{100-500} classes for the sx app's violet menu bar
- Add highlight.py custom syntax highlighter (sx, python, bash)
IMPORTANT: tw.css must contain bg-violet-{100-500} rules for the sx
app's menu bar. Do not rebuild tw.css without ensuring violet classes
are included (via safelist or content paths).

- OOB nav updates: AJAX navigation now swaps both menu bar levels
(main nav highlighting + sub-nav with current page) using the same
oob_header_sx/oob_page_sx pattern as blog/market/events
- Enable OAuth for sx and test apps (removed from _NO_OAUTH, added sx
to ALLOWED_CLIENTS, added app_urls for sx/test/orders)
- Fetch real cross-service fragments (cart-mini, auth-menu, nav-tree)
instead of hardcoding empty values
- Add :selected param to ~menu-row-sx for white text current-page label
- Fix duplicate element IDs: use menu-row-sx child_id/child mechanism
instead of manual header_child_sx wrappers
- Fix home page copy: "Server-rendered DOM over the wire (no HTML)"

The existing prism.css sets color:black on code elements. Dark
bg-stone-900 backgrounds made text invisible. Switched to bg-stone-50

New public-facing service documenting the s-expression rendering engine.
Modelled on four.htmx.org with violet theme, all content rendered via sx.
Sections: docs, reference, protocols, examples (live demos), essays
(including "sx sucks"). No database — purely static documentation.
Port 8012, Redis DB 10. CI and deploy.sh updated with app_dir() mapping
for sx_docs -> sx/ directory. Caddy reverse proxy entry added separately.
