3cce3df5b0 Fix standalone OOB layout: delegate to shared layout for proper OOB swaps
The standalone OOB layout was returning nil, so SPA navigation
responses had no OOB swap structure. The header island wasn't
included in responses, so:
- Colour state was lost (island not morphed, signals reset)
- Copyright path wasn't updated (lake not in response)

Now delegates to ~shared:layout/oob-sx which wraps content in
proper OOB sections (filter, aside, menu, main-panel). The header
island with updated :path is included in the content, allowing
the morph to preserve island signals and update lakes.

318c818728 Lazy JIT compilation: lambdas compile to bytecode on first call
Replace AOT adapter compilation with lazy JIT — each named lambda is
compiled to VM bytecode on first call, cached in l_compiled field for
subsequent calls. Compilation failures fall back to CEK gracefully.

VM types (vm_code, vm_upvalue_cell, vm_closure) moved to sx_types.ml
mutual recursion block. Lambda and Component records gain mutable
l_compiled/c_compiled cache fields. jit_compile_lambda in sx_vm.ml
wraps body as (fn (params) body), invokes spec/compiler.sx via CEK,
extracts inner closure from OP_CLOSURE constant.

JIT hooks in both paths:
- vm_call: Lambda calls from compiled VM code
- continue_with_call: Lambda calls from CEK step loop (injected by
  bootstrap.py post-processing)

Pre-mark sentinel prevents re-entrancy (compile function itself was
hanging when JIT'd mid-compilation). VM execution errors caught and
fall back to CEK with sentinel marking.

Also: add kbd/samp/var to HTML_TAGS, rebuild sx-browser.js, add page
URL to sx-page-full-py timing log.

Performance: first page 28s (JIT compiles 17 functions), subsequent
pages 0.31s home / 0.71s wittgenstein (was 2.3s). All 1945 tests pass.

df461beec2 SxExpr aser wire format fix + Playwright test infrastructure + blob protocol
Aser serialization: aser-call/fragment now return SxExpr instead of String.
serialize/inspect passes SxExpr through unquoted, preventing the double-
escaping (\" → \\\" ) that broke client-side parsing when aser wire format
was output via raw! into <script> tags. Added make-sx-expr + sx-expr-source
primitives to OCaml and JS hosts.

Binary blob protocol: eval, aser, aser-slot, and sx-page-full now send SX
source as length-prefixed blobs instead of escaped strings. Eliminates pipe
desync from concurrent requests and removes all string-escape round-trips
between Python and OCaml.

Bridge safety: re-entrancy guard (_in_io_handler) raises immediately if an
IO handler tries to call the bridge, preventing silent deadlocks.

Fetch error logging: orchestration.sx error callback now logs method + URL
via log-warn. Platform catches (fetchAndRestore, fetchPreload, bindBoostForm)
also log errors instead of silently swallowing them.

Transpiler fixes: makeEnv, scopePeek, scopeEmit, makeSxExpr added as
platform function definitions + transpiler mappings — were referenced in
transpiled code but never defined as JS functions.

Playwright test infrastructure:
- nav() captures JS errors and fails fast with the actual error message
- Checks for [object Object] rendering artifacts
- New tests: delete-row interaction, full page refresh, back button,
  direct load with fresh context, code block content verification
- Default base URL changed to localhost:8013 (standalone dev server)
- docker-compose.dev-sx.yml: port 8013 exposed for local testing
- test-sx-build.sh: build + unit tests + Playwright smoke tests

Geography content: index page component written (sx/sx/geography/index.sx)
describing OCaml evaluator, wire formats, rendering pipeline, and topic
links. Wiring blocked by aser-expand-component children passing issue.

Tests: 1080/1080 JS, 952/952 OCaml, 66/66 Playwright

373a4f0134 Fix pipe desync: send_ok_raw escapes newlines, expand-components? in env
- send_ok_raw: when SX wire format contains newlines (string literals),
  fall back to (ok "...escaped...") instead of (ok-raw ...) to keep
  the pipe single-line. Prevents multi-line responses from desyncing
  subsequent requests.
- expand-components? flag set in kernel env (not just VM adapter globals)
  so aser-list's env-has? check finds it during component expansion.
- SX_STANDALONE: restore no_oauth but generate CSRF via session cookie
  so mutation handlers (DELETE etc.) still work without account service.
- Shell statics injection: only inject small values (hashes, URLs) as
  kernel vars. Large blobs (CSS, component_defs) use placeholder tokens.

ae0e87fbf8 VM aser-slot → sx-page-full: single-call page render, 0.55s warm
Compiler fixes:
- Upvalue re-lookup returns own position (uv-index), not parent slot
- Spec: cek-call uses (make-env) not (dict) — OCaml Dict≠Env
- Bootstrap post-processes transpiler Dict→Env for cek_call

VM runtime fixes:
- compile_adapter evaluates constant defines (SPECIAL_FORM_NAMES etc.)
  via execute_module instead of wrapping as NativeFn closures
- Native primitives: map-indexed, some, every?
- Nil-safe HO forms: map/filter/for-each/some/every? accept nil as empty
- expand-components? set in kernel env (not just VM globals)
- unwrap_env diagnostic: reports actual type received

sx-page-full command:
- Single OCaml call: aser-slot body + render-to-html shell
- Eliminates two pipe round-trips (was: aser-slot→Python→shell render)
- Shell statics (component_defs, CSS, pages_sx) cached in Python,
  injected into kernel once, referenced by symbol in per-request command
- Large blobs use placeholder tokens — Python splices post-render,
  pipe transfers ~51KB instead of 2MB

Performance (warm):
- Server total: 0.55s (was ~2s)
- aser-slot VM: 0.3s, shell render: 0.01s, pipe: 0.06s
- kwargs computation: 0.000s (cached)

SX_STANDALONE mode for sx_docs dev (skips fragment fetches).

8707f21ca2 Single-pass aser_slot for HTMX path + kernel eval timing + stable hash
Eliminated double-aser for HTMX requests: build OOB wrapper AST
(~shared:layout/oob-sx :content wrapped_ast) and aser_slot in ONE
pass — same pattern as the full-page path. Halves aser_slot calls.

Added kernel-side timing to stderr:
  [aser-slot] eval=3.6s io_flush=0.0s batched=3 result=22235 chars

Results show batch IO works (io_flush=0.0s for 3 highlight calls)
and the bottleneck is pure CEK evaluation time, not IO.

Performance after single-pass fix:
  Home: 0.7s eval (was 2.2s total)
  Reactive: 3.6s eval (was 6.8s total)
  Language: 1.1s eval (was 18.9s total — double-aser eliminated)

d3b3b4b720 Fix pipe desync: async drain on _send, robust Playwright tests
Root cause: OcamlBridge._send() used write() without drain().
asyncio.StreamWriter buffers writes — without drain(), multiple
commands accumulate and flush as a batch. The kernel processes
them sequentially, sending responses, but Python only reads one
response per command → pipe desync → "unexpected response" errors.

Fix: _send() is now async, calls drain() after every write.
All 14 callers updated to await.

Playwright tests rewritten:
- test_home_has_header: verifies #logo-opacity visible (was only
  checking for "sx" text — never caught missing header)
- test_home_has_nav_children: Geography link must be visible
- test_home_has_main_panel: #main-panel must have child elements
- TestDirectPageLoad: fresh browser.new_context() per test to
  avoid stale component hash in localStorage
- _setup_error_capture + _check_no_fatal_errors helpers

_render_to_sx uses aser_slot (not aser) — layout wrappers contain
re-parsed content that needs full expansion capability.

f819fda587 aser_slot migration: single-pass expansion, pipe desync fix, _render_to_sx
Three fixes completing the aser_slot migration:

1. Single-pass full-page rendering: eval_sx_url builds layout+content
   AST and aser_slots it in ONE call — avoids double-aser where
   re-parsed content hits "Undefined symbol: title/deref" errors.

2. Pipe desync fix: _inject_helpers_locked runs INSIDE the aser_slot
   lock acquisition (not as a separate lock). Prevents interleaved
   commands from other coroutines between injection and aser-slot.

3. _render_to_sx uses aser_slot (not aser): layout wrappers like
   oob_page_sx contain re-parsed content from earlier aser_slot
   calls. Regular aser fails on symbols that were bound during
   the earlier expansion. aser_slot handles them correctly.

HTMX path: aser_slot the content, then oob_page_sx wraps it.
Full page path: build (~shared:layout/app-body :content wrapped_ast),
aser_slot in one pass, pass directly to sx_page.

New Playwright tests: test_navigate_geography_to_reactive,
test_direct_load_reactive_page.

109ca7c70b Fix aser server-affinity expansion: keyword values, OOB wrapper, page helpers
Three bugs in aser-expand-component (adapter-sx.sx):
- Keyword values were eval'd (eval-expr can't handle <>, HTML tags);
  now asered, matching the aser's rendering capabilities
- Missing default nil binding for unset &key params (caused
  "Undefined symbol" errors for optional params like header-rows)
- aserCall string-quoted keyword values that were already serialized
  SX — now inlines values starting with "(" directly

Server-affinity annotations for layout/nav shells:
- ~shared:layout/app-body, ~shared:layout/oob-sx — page structure
- ~layouts/nav-sibling-row, ~layouts/nav-children — server-side data
- ~layouts/doc already had :affinity :server
- ~cssx/flush marked :affinity :client (browser-only state)

Navigation fix: restore oob_page_sx wrapper for HTMX responses
so #main-panel section exists for sx-select/sx-swap targeting.

OCaml bridge: lazy page helper injection into kernel via IO proxy
(define name (fn (...) (helper "name" ...))) — enables aser_slot
to evaluate highlight/component-source etc. via coroutine bridge.

Playwright tests: added pageerror listener to test_no_console_errors,
new test_navigate_from_home_to_geography for HTMX nav regression.

171c18d3be Aser server-affinity component expansion + readline buffer fix
adapter-sx.sx: aser-expand-component expands :affinity :server components
inline during SX wire format serialization. Binds keyword args via
eval-expr, children via aser (handles HTML tags), then asers the body.

ocaml_bridge.py: 10MB readline buffer for large spec responses.
nav-data.sx: evaluator.sx filename fix.

Page rendering stays on Python _eval_slot for now — full OCaml rendering
needs the page shell IO (headers, CSRF, CSS) migrated to OCaml IO bridge.

8373c6cf16 SX spec introspection: the spec examines itself via sx-parse
spec-introspect.sx: pure SX functions that read, parse, and analyze
spec files. No Python. The spec IS data — a macro transforms it into
explorer UI components.

- spec-explore: reads spec file via IO, parses with sx-parse, extracts
  sections/defines/effects/params, produces explorer data dict
- spec-form-name/kind/effects/params/source: individual extractors
- spec-group-sections: groups defines into sections
- spec-compute-stats: aggregate effect/define counts

OCaml kernel fixes:
- nth handles strings (character indexing for parser)
- ident-start?, ident-char?, char-numeric?, parse-number: platform
  primitives needed by spec/parser.sx when loaded at runtime
- _find_spec_file: searches spec/, web/, shared/sx/ref/ for spec files

83/84 Playwright tests pass. The 1 failure is client-side re-rendering
of the spec explorer (the client evaluates defpage content which calls
find-spec — unavailable on the client).

71c2003a60 OCaml evaluator for page dispatch + handler aser, 83/83 Playwright tests
Major architectural change: page function dispatch and handler execution
now go through the OCaml kernel instead of the Python bootstrapped evaluator.

OCaml integration:
- Page dispatch: bridge.eval() evaluates SX URL expressions (geography, marshes, etc.)
- Handler aser: bridge.aser() serializes handler responses as SX wire format
- _ensure_components loads all .sx files into OCaml kernel (spec, web adapter, handlers)
- defhandler/defpage registered as no-op special forms so handler files load
- helper IO primitive dispatches to Python page helpers + IO handlers
- ok-raw response format for SX wire format (no double-escaping)
- Natural list serialization in eval (no (list ...) wrapper)
- Clean pipe: _read_until_ok always sends io-response on error

SX adapter (aser):
- scope-emit!/scope-peek aliases to avoid CEK special form conflict
- aser-fragment/aser-call: strings starting with "(" pass through unserialized
- Registered cond-scheme?, is-else-clause?, primitive?, get-primitive in kernel
- random-int, parse-int as kernel primitives; json-encode, into via IO bridge

Handler migration:
- All IO calls converted to (helper "name" args...) pattern
- request-arg, request-form, state-get, state-set!, now, component-source etc.
- Fixed bare (effect ...) in island bodies leaking disposer functions as text
- Fixed lower-case → lower, ~search-results → ~examples/search-results

Reactive islands:
- sx-hydrate-islands called after client-side navigation swap
- force-dispose-islands-in for outerHTML swaps (clears hydration markers)
- clear-processed! platform primitive for re-hydration

Content restructuring:
- Design, event bridge, named stores, phase 2 consolidated into reactive overview
- Marshes split into overview + 5 example sub-pages
- Nav links use sx-get/sx-target for client-side navigation

Playwright test suite (sx/tests/test_demos.py):
- 83 tests covering hypermedia demos, reactive islands, marshes, spec explorer
- Server-side rendering, handler interactions, island hydration, navigation

core with zero web, rendering, or type-system knowledge. 2531 → 2313 lines.

- Add extensible special form registry (*custom-special-forms* + register-special-form!)
- Add render dispatch hooks (*render-check* / *render-fn*) replacing hardcoded render-active?/is-render-expr?/render-expr
- Extract freeze scopes → spec/freeze.sx (library, not core)
- Extract content addressing → spec/content.sx (library, not core)
- Move sf-deftype/sf-defeffect → spec/types.sx (self-registering)
- Move sf-defstyle → web/forms.sx (self-registering with all web forms)
- Move web tests (defpage, streaming) → web/tests/test-forms.sx
- Add is-else-clause? helper (replaces 5 inline patterns)
- Make escape-html/escape-attr library functions in render.sx (pure SX, not platform-provided)
- Add foundations plan: Step 3.5 (data representations), Step 3.7 (verified components), OCaml for Step 4d
- Update all three bootstrappers (JS 957/957, Python 744/744, OCaml 952/952)

Evaluator: data-first higher-order forms — ho-swap-args auto-detects

17 new tests in test-cek-advanced.sx.

Fix plan pages: add mother-language, isolated-evaluator, rust-wasm-host
to page-functions.sx plan() — were in defpage but missing from URL router.

Aser error handling: pages.py now catches EvalError separately, renders
visible error banner instead of silently sending empty content. All
except blocks include traceback in logs.

Scope primitives: register collect!/collected/clear-collected!/emitted/
emit!/context in shared/sx/primitives.py so hand-written _aser can

Bugs found and documented:
- case in render context returns DOM object (CEK dispatches case
  before HTML adapter sees it — use cond instead for render)

provide/context and scope/emit!/emitted now use CEK continuation
frames instead of an imperative global stack. Scope state is part

- ScopeAccFrame: holds name + mutable emitted list

New CEK special forms:
- context: walks kont for nearest ProvideFrame, returns value
- emit!: walks kont for nearest ScopeAccFrame, appends to emitted
- emitted: walks kont for nearest ScopeAccFrame, returns list

Kont walkers: kont-find-provide, kont-find-scope-acc

719da7914e Multi-shot delimited continuations: 868/870 passing
All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 9m5s
Continuations are now multi-shot — k can be invoked multiple times.
Each invocation runs the captured frames via nested cek-run and
returns the result to the caller's continuation.

Fix: continue-with-call runs ONLY the captured delimited frames
(not rest-kont), so the continuation terminates and returns rather
than escaping to the outer program.

Fixed 4 continuation tests:
- shift with multiple invokes: (list (k 10) (k 20)) → (11 21)
- k returned from reset: continuation callable after escaping
- invoke k multiple times: same k reusable
- k in data structure: store in list, retrieve, invoke

Remaining 2 failures: scope/provide across shift boundaries.
These need scope state tracked in frames (not imperative push/pop).

c6a662c980 Phase 4: Eliminate nested CEK from HO form handlers
Higher-order forms (map, filter, reduce, some, every?, for-each,
map-indexed) now evaluate their arguments via CEK frames instead
of nested trampoline(eval-expr(...)) calls.

Added HoSetupFrame — staged evaluation of HO form arguments.
When all args are evaluated, ho-setup-dispatch sets up the
iteration frame. This keeps a single linear CEK continuation
chain instead of spawning nested CEK instances.

14 nested eval-expr calls eliminated (39 → 25 remaining).
The remaining 25 are in delegate functions (sf-letrec, sf-scope,
parse-keyword-args, qq-expand, etc.) called infrequently.

b3a7df45e6 Deep concurrent CEK spec in foundations plan
Some checks failed
Build and Deploy / build-and-deploy (push) Has been cancelled
Steps 1-3 marked done. Step 4 (Concurrent CEK) fully specced:

4.1 Spawn — freeze thunk, run on worker, resolve signal
4.2 Channels — buffered, unbuffered, broadcast, select
4.3 Fork/Join — spawn N, collect results as signals
4.4 Scheduler — round-robin, priority, work-stealing, DAG-ordered
4.5 Content-addressed concurrency — memoize, distribute, verify
4.6 Host mapping — JS/Python/Haskell/Rust primitives table
4.7 Roadmap — 9 phases from Web Worker spawn to linear channels

Step 5 (Linear Effects) outlined: affine channels, linear scopes,
session types, resource handles.

f7debec7c6 Content-addressed computation: freeze → hash → CID → thaw
Some checks failed
Build and Deploy / build-and-deploy (push) Has been cancelled
Hash frozen SX to a content identifier (djb2 → hex). Same state
always produces the same CID. Store by CID, retrieve by CID.

- content-hash: djb2 hash of SX text → hex string
- content-put/get: in-memory content store
- freeze-to-cid: freeze scope → store → return CID
- thaw-from-cid: look up CID → thaw signals
- char-code-at / to-hex primitives for both platforms
- Live demo: counter + name widget, content-address button,
  CID display, restore from CID input, CID history

cb4f4b85e5 Named freeze scopes for serializable reactive state
All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 3m20s
Replace raw CEK state serialization with named freeze scopes.
A freeze scope collects signals registered within it. On freeze,
signal values are serialized to SX. On thaw, values are restored.

- freeze-scope: scoped effect delimiter for signal collection
- freeze-signal: register a signal with a name in the current scope
- cek-freeze-scope / cek-thaw-scope: freeze/thaw by scope name
- freeze-to-sx / thaw-from-sx: full SX text round-trip
- cek-freeze-all / cek-thaw-all: batch operations

Also: register boolean?, symbol?, keyword? predicates in both
Python and JS platforms with proper var aliases.

Demo: counter + name input with Freeze/Thaw buttons.
Frozen SX: {:name "demo" :signals {:count 5 :name "world"}}

When a tag's open step is evaluated, both its opening and closing
brackets go big+bold together. Previously close ) had the close
step index so it stayed faint until much later.

169097097c Imperative code view: spans built once, classes updated on each step
All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 27s
Code view uses a lake with imperative DOM spans. Each token has its
base syntax colour class stored. On each step, update-code-highlight
iterates all spans and sets class based on step-idx: evaluated tokens
go bold, current step gets violet bg, future stays normal.

No reactive re-rendering of the code view — direct DOM class updates.

Cache the style element reference in _cssx-style-el so flush-cssx-to-dom

41f4772ba7 Strip legacy CSS from SX app: no Prism, Ghost, FontAwesome extras
All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 5m10s
Add css_extras parameter to create_base_app. Legacy apps (blog, market
etc) get the default extras (basics.css, cards.css, blog-content.css,
prism.css, FontAwesome). SX app passes css_extras=[] — it uses CSSX
for styling and custom highlighting, not Prism/FA/Ghost.

Reduces <style id="sx-css"> from ~100KB+ of irrelevant CSS to ~5KB
of Tailwind resets + only the utility rules the page actually uses.

A defisland that lets users type an SX expression, step through CEK
evaluation one transition at a time, and see C/E/K registers update
live. Demonstrates that cek-step is pure data->data.

- cek.sx geography: add ~geography/cek/demo-stepper island with
  source input, step/run/reset buttons, state display, step history
- platform_js.py: register CEK stepping primitives (make-cek-state,
  cek-step, cek-terminal?, cek-value, make-env, sx-serialize) so
  island code can access them

Plato's allegory of the cave applied to web development: HTML/CSS/JS as
shadows on the wall, s-expressions as Forms, the bootstrapper as
demiurge, anamnesis as the wire format's efficiency, the divided line
as SX's rendering hierarchy, and the Form of the Good as the principle
that representation and thing represented should be identical.

The depth axis is done — CEK (Layer 0) through patterns (Layer 4) are
all specced, bootstrapped, and tested. Rewrite the plan to reflect
reality and reframe the next steps as validation (serialization,
stepping debugger, content-addressed computation) before building
superstructure (concurrent CEK, linear effects).

init-client.sx contains browser-only code (dom-listen, collect! cssx).
It was in sx/sx/ which load_sx_dir scans and evaluates server-side,
causing "Undefined symbol: dom-listen". Move to sx/init-client.sx
which is outside the component load path.

919998be1c Move SX app CSS and init behavior from Python to init.sx
Styles (indicator, jiggle animation) and nav aria-selected behavior
were inline Python strings in sx/app.py. Now they live in sx/sx/init.sx
as proper SX source — styles via collect! "cssx", nav via dom-listen.

The shell's inline_css is empty; CSSX handles style injection on boot.

455e48df07 Replace invoke with cek-call in reactive island primitives
All signal operations (computed, effect, batch, etc.) now dispatch
function calls through cek-call, which routes SX lambdas via cek-run
and native callables via apply. This replaces the invoke shim.

Key changes:
- cek.sx: add cek-call (defined before reactive-shift-deref), replace
  invoke in subscriber disposal and ReactiveResetFrame handler
- signals.sx: replace all 11 invoke calls with cek-call
- js.sx: fix octal escape in js-quote-string (char-from-code 0)
- platform_js.py: fix JS append to match Python (list concat semantics),
  add Continuation type guard in PLATFORM_CEK_JS, add scheduleIdle
  safety check, module ordering (cek before signals)
- platform_py.py: fix ident-char regex (remove [ ] from valid chars),
  module ordering (cek before signals)
- run_js_sx.py: emit PLATFORM_CEK_JS before transpiled spec files
- page-functions.sx: add cek and provide page functions for SX URLs

Add reactive runtime plan to sx-docs: 7 feature layers (ref, foreign
FFI, state machines, commands with undo/redo, render loops, keyed
lists, client-first app shell) — zero new platform primitives.
