dc5da2f5ed sx-http: header island working, stepper partial, CSSX source included
Include cssx.sx source in component-defs for client CSSX runtime.
Island placeholders now contain SX call expression for client hydration.
escape_sx_string only escapes </script, not all </ sequences.
serialize_value: no (list) wrapper, matching Python serialize() exactly.

Homepage: header renders (<sx>, tagline, copyright), stepper shows
raw SX (cssx/tw not expanding client-side). Geography fully rendered
including island hydration.

31ae9b5110 sx-http: fix serialize_value + include all defines in component-defs
serialize_value: all lists emit (items...) not (list items...), matching
Python serialize() exactly. Empty lists emit (). This fixes let bindings,
fn params, and data structures for client-side parsing.

Component-defs now include named lambdas, macros, dicts, and other named
values from the env — client needs CSSX functions (cssx-process-token,
cssx-colour-props, cssx-spacing-props etc.) for island hydration.

Fixes: cssx-process-token, cssx-colour-props undefined errors.
Geography page: fully rendered with header island hydration working.
Homepage: nav renders, no error banners, stepper silent.

900de713c3 sx-http: fix serialize_value for client-side parsing + remove debug code
serialize_value: lists with symbol head emit (fn args...) not (list fn args).
This lets the client SX parser recognise special forms like let, when, cond
inside component-defs. Data lists (starting with non-symbols) keep the
(list ...) wrapper.

Fixes "Undefined symbol: let" WASM error that broke all island hydration.
Header island now reaches the JIT evaluator (fails on for-each VM error,
not parsing). Geography, SXTP, CEK pages fully rendered.

Removed debug logging (ssr-debug, debug dump, debug endpoint).

39eb217c15 sx-http: fix homepage (bare symbol → fn call) + auto-quote slugs + resilient SSR
Homepage fix: path_expr "home" was evaluated as a symbol lookup (returning
the Lambda) instead of a function call. Now wraps bare symbols in a list:
home → (home) → calls the page function → returns component call.

Slug routing: auto_quote converts unknown symbols to strings before eval.
(etc (plan sx-host)) → (etc (plan "sx-host")) — resolves nested slug URLs.

Resilient SSR: render_to_buf catches Eval_error per-element and continues
rendering. Partial SSR output preserved even when some elements fail.

WASM kernel rebuilt (define shorthand + island placeholder changes).

Remaining: WASM kernel "Undefined symbol: let" — pre-existing bug in
client-side component-defs parsing. (list let ...) triggers symbol lookup
instead of special form recognition. Affects island hydration on all pages.

303fc5c319 sx-http: fix </script escaping in serialize_value, inline component-defs
escape_sx_string now escapes </ as <\\/ inside SX string literals,
matching Python's serialize() behavior. This prevents the HTML parser
from matching </script> inside component-defs strings while keeping
the SX valid for the client parser.

Component-defs back to inline <script data-components> (reverts
external endpoint approach). init-sx triggers client render when
sx-root is empty.

Geography page: fully rendered with header, nav, content, styling.
Header island hydration warning (Undefined symbol: let) is a
pre-existing WASM kernel issue, not related to the HTTP server.

f1d08bbbe9 sx-http: island SSR → always placeholder, external component-defs endpoint
Islands now always emit <span data-sx-island="name"> placeholder
instead of attempting SSR. Island bodies contain client-only symbols
(signals, DOM refs) that cascade errors during native render.

Component-defs moved to /static/sx-components.sx endpoint instead of
inline <script> — avoids </script> escaping issues that broke the
client-side SX parser.

Remaining: client WASM kernel not loading components from external
endpoint (expects inline script tag). Need to configure client boot
to fetch from /static/sx-components.sx.

10037a0b04 sx-http: escape </script in defs, pages-sx registry, SSR fallback, redirect
- Escape </script sequences in component-defs (replace </ with <\/ before s/S)
- Build pages-sx registry from defpage definitions (51 routes for client router)
- SSR fallback: emit minimal layout HTML when full SSR fails
- Redirect / → /sx/
- Load sxc/ components for ~docs/page
- Block .wasm.assets/ build artifacts but allow .wasm runtime files

Geography page renders correctly with full styling and content.
Homepage still blank — client boot doesn't render from page-sx on
initial load (only on navigation). Needs homepage SSR to succeed,
which requires fixing the stepper island's <home symbol.

f905ff287c sx-http: static file serving + inline CSS + cache-bust hashes
OCaml HTTP server now serves /static/* files with MIME types, immutable
cache headers, and in-memory caching. Computes MD5 hashes for JS/WASM
files and injects them as ?v= cache-busting query params.

Inline CSS: reads tw.css + basics.css at startup, injects into
<style id="sx-css"> tag. Pages now render with full Tailwind styling.

Shell statics now include real file hashes:
  sx-js-hash, body-js-hash, wasm-hash — 12-char MD5 hex

Docker compose: mounts shared/static as /app/static for the container.

7108b01e37 sx-http: response cache — 323 req/s, 3ms TTFB, 47x throughput vs Quart
In-memory response cache populated during startup pre-warm. Cache misses
render on-demand and cache the result. All cached pages serve in 2-14ms.

Performance (cached, 2 worker domains, 2MB RSS):
  Homepage:  3-10ms TTFB (was 202ms Quart) — 20-60x faster
  Geography: 3-14ms TTFB (was 144ms Quart) — 10-48x faster
  Reactive:  2-5ms TTFB (was 187ms Quart) — 37-94x faster
  Throughput: 323 req/s at c=10 (was 6.8 Quart) — 47x higher
  Memory: 2MB (was 570MB Quart) — 285x less

Cache invalidation: not yet implemented (restart to refresh).
Future: file watcher or content-hash based invalidation.

abca040a5d sx-http: pre-warm pages on startup for JIT hot-start
Render 5 key pages during startup to trigger JIT compilation of page
functions, aser, render-to-html, and all component paths. Steady-state
performance after warmup:

  Homepage:  212-280ms (aser=136-173ms, ssr=44-90ms)
  Geography: 282-354ms (aser=215-273ms, ssr=44-61ms)
  Reactive:  356-522ms (aser=306-390ms, ssr=38-109ms)

SSR phase is fast (streaming renderer). Aser is the bottleneck —
response caching eliminates it for static pages.

1412648f6e sx-http: buffer-based streaming renderer, eliminates string allocation
New render_to_buf / render_to_html_streaming in sx_render.ml — writes
HTML directly to a Buffer.t instead of building intermediate strings.
Eliminates hundreds of string concatenations per page render.

Full parallel renderer: render_to_buf, render_element_buf,
render_component_buf, render_cond_buf, render_let_buf, render_map_buf,
render_for_each_buf — all buffer-native.

HTTP server SSR + shell now use streaming renderer.

3620a433c1 sx-http: log JIT fallbacks once per function, not silently or flooding
JIT runtime errors now log once per function name via _jit_warned
hashtable, then stay quiet for that function. No more silent swallowing
(which hid real errors) or per-call flooding (which spammed thousands
of lines and blocked the server).

VM-level fallbacks (inside JIT-compiled code calling other JIT code)
are silent — dedup happens at the hook level.

8e1870246d sx-http: OCaml 5 domain pool + per-request env safety
Domain pool with N workers (Domain.recommended_domain_count), mutex+
condition queue for request dispatch. Each domain has its own minor
heap — GC pauses don't block other requests.

expand-components? bound once at startup (always true in HTTP mode)
instead of per-request mutation. Shell rendering uses native

1d064a1914 sx-http: silent JIT fallback, load signals+engine, fix render-to-html
JIT runtime errors now silently fall back to CEK without disabling the
compiled bytecode or logging. This prevents render-to-html from being
permanently disabled when one page has an unresolved symbol (e.g. the
homepage stepper's <home).

Load spec/signals.sx and web/engine.sx for reactive primitives.
Skip test files and non-rendering directories (tests/, plans/, essays/).

Performance with JIT active (warm, single process, 2MB RSS):
- Aser (component expansion): 21-87ms — faster than Quart baseline
- SSR + shell: variable due to homepage <home fallback issue
- Geography total: ~500ms when JIT stays active

- Load spec/signals.sx + web/engine.sx for reactive primitives
- Recursive directory loading for subdirectory components (geography/, etc.)
- Re-bind native variadic assoc after stdlib.sx overwrites it
- Skip test files, plans/, essays/ directories during HTTP load
- Homepage aser: 21-38ms warm, Geography aser: 39-87ms warm

Remaining: render-to-html JIT gets disabled by <home symbol error on

0d5770729f sx-host step 3: HTTP server mode + define shorthand + SX highlighter
HTTP server (--http PORT): OCaml serves sx-docs directly, no Python.
Loads components at startup, routes /sx/ URLs, renders full pages with
shell. Geography page: 124ms TTFB (vs 144ms Quart). Single process.

define shorthand: (define (name args) body) desugars to
(define name (fn (args) body)) in the CEK step function.

SX highlighter (lib/highlight.sx): pure SX syntax highlighting with
Tailwind spans. Tokenizes SX/Lisp code — comments, strings, keywords,
components, specials, numbers, booleans. Replaces Python highlight.py.

Platform constructors: make-lambda, make-component, make-island,
make-macro, make-thunk, make-env + accessor functions bound for
evaluator.sx compatibility in HTTP mode.

Tests: 1116/1117 OCaml, 7/7 Playwright (main tree).

153f02c672 sx-host plan steps 1-2: defhelper + SX config + SXTP spec + nav tools
Step 1 — defhelper: SX-defined page data helpers replace Python helpers.
(defhelper name (params) body) in .sx files, using existing IO primitives
(query, action, service). Loaded into OCaml kernel as pure SX defines.

Step 2 — SX config: app-config.sx replaces app-config.yaml with (defconfig)
form. (env-get "VAR") resolves secrets from environment. Kebab-to-underscore
aliasing ensures backward compatibility with all 174 config consumers.

Also: SXTP protocol spec (applications/sxtp/spec.sx), docs article,
sx_nav move/delete modes, reactive-runtime moved to geography.

0cae1fbb6b Fix event-bridge + add client? primitive + header store foundation
- Event-bridge: rewrite island to use document-level addEventListener
  via effect + host-callback, bypassing broken container-ref + schedule-idle.
  Also use host-get for event-detail (WASM host handles).

- Add client? primitive: false on server (sx_primitives._is_client ref),
  true in browser (sx_browser.ml sets ref). Enables SSR-safe conditional
  logic for client-only features like def-store.

- Header island: use def-store for idx/shade signals when client? is true,
  falling back to plain signals on server. Foundation for SPA nav state
  preservation (store registry persistence still needs work).

- Remove unused client? K.eval override from sx-platform.js.

c923a34fa8 Fix WASM browser click handlers: 8 bugs, 50 new VM tests
The sx-get links were doing full page refreshes because click handlers
never attached. Root causes: VM frame management bug, missing primitives,
CEK/VM type dispatch mismatch, and silent error swallowing.

Fixes:
- VM frame exhaustion: frames <- [] now properly pops to rest_frames
- length primitive: add alias for len in OCaml primitives
- call_sx_fn: use sx_call directly instead of eval_expr (CEK checks
  for type "lambda" but VmClosure reports "function")
- Boot error surfacing: Sx.init() now has try/catch + failure summary
- Callback error surfacing: catch-all handler for non-Eval_error exceptions
- Silent JIT failures: log before CEK fallback instead of swallowing
- vm→env sync: loadModule now calls sync_vm_to_env()
- sx_build_bytecode MCP tool added for bytecode compilation

Tests: 50 new tests across test-vm.sx and test-vm-primitives.sx covering
nested VM calls, frame integrity, CEK bridge, primitive availability,
cross-module symbol resolution, and callback dispatch.

96d0d29f10 Add capability-based evaluation context primitives
Four new primitives for capability-aware evaluation:
- with-capabilities: restrict capabilities for a body (sets global cap stack)
- current-capabilities: query current capability set
- has-capability?: check if a specific capability is available
- require-capability!: assert a capability, error if missing

Uses a global OCaml ref (cap_stack) for cross-CEK-boundary visibility.
Note: with-capabilities error propagation from CEK sub-evaluations
needs deeper integration — the primitives themselves work correctly.

  nav-applications, nav-etc, nav-tools, nav-tree
- Add Tools top-level nav category with SX Tools and Services pages
- New services-tools.sx page documenting the rose-ash-services MCP server

JS build fixes (fixes 5 Playwright failures):
- Wire web/web-signals.sx into JS build (stores, events, resources)
- Add cek-try primitive to JS platform (island hydration error handling)
- Merge PRIMITIVES into getRenderEnv (island env was missing primitives)
- Rename web/signals.sx → web/web-signals.sx to avoid spec/ collision

New MCP tools:
- sx_trace: step-through CEK evaluation showing lookups, calls, returns
- sx_deps: dependency analysis — free symbols + cross-file resolution
- sx_build_manifest: show build contents for JS and OCaml targets
- sx_harness_eval extended: multi-file loading + setup expressions

Deep path bug fix:
- Native OCaml list-replace and navigate bypass CEK callback chain
- Fixes sx_replace_node and sx_read_subtree corruption on paths 6+ deep

b53a0fabea Inline test runner: 5/5 temperature converter tests passing
Fixed three fundamental issues:
1. cek-try arg passing: handler was called with raw string instead of
   (List [String msg]), causing "lambda expects 1 args, got N" errors
2. Silent island hydration failures: hydrate-island now wraps body
   render in cek-try, displaying red error box with stack trace instead
   of empty div. No more silent failures.
3. swap! thunk leak: apply result wasn't trampolined, storing thunks
   as signal values instead of evaluated results

Also fixed: assert= uses = instead of equal? for value comparison,
assert-signal-value uses deref instead of signal-value, HTML entity
decoding in script tag test source via host-call replaceAll.

Temperature converter demo page now shows live test results:
  ✓ initial celsius is 20
  ✓ computed fahrenheit = celsius * 1.8 + 32
  ✓ +5 increments celsius
  ✓ fahrenheit updates on celsius change
  ✓ multiple clicks accumulate

1116/1116 OCaml tests pass.

5754a9ff9f Add inline test runner for temperature converter demo
Temperature converter tests (6 tests): initial value, computed
fahrenheit derivation, +5/-5 click handlers, reactive propagation,
multiple click accumulation.

New components:
- sx/sx/reactive-islands/test-runner.sx — reusable defisland that
  parses test source, runs defsuite/deftest forms via cek-eval, and
  displays pass/fail results with re-run button
- sx/sx/reactive-islands/test-temperature.sx — standalone test file

Added cek-try primitive to both browser (sx_browser.ml) and server
(sx_server.ml) for safe test execution with error catching.

Browser bundle now includes harness files (harness.sx,
harness-reactive.sx, harness-web.sx) for inline test execution.

Known: SSR renders test runner body instead of placeholder, causing
arity error on complex str expressions. Needs island SSR handling fix.

fea44f9fcc Add reactive runtime demos + sx-web federation plan
7 interactive island demos for the reactive runtime layers:
- L0 Ref (timer + DOM handle), L1 Foreign (canvas via host-call),
  L2 Machine (traffic light), L3 Commands (undo/redo),
  L4 Loop (bouncing ball), L5 Keyed Lists, L6 App Shell

Fix OCaml build: add (wrapped false) to lib/dune, remove Sx. qualifiers.
Fix JS build: include dom-lib + browser-lib in adapter compilation.

New plan: sx-web federated component web — browser nodes via WebTransport,
server nodes via IPFS, in-browser authoring, AI composition layer.

b104663481 Split signals: core spec (spec/signals.sx) + web extensions (web/signals.sx)
Core reactive primitives (signal, deref, reset!, swap!, computed, effect,
batch, notify-subscribers, dispose-computed, with-island-scope,
register-in-scope) moved to spec/signals.sx — pure SX, zero platform
dependencies. Usable by any host: web, CLI, embedded, server, harness.

Web extensions (marsh scopes, stores, event bridge, resource) remain in
web/signals.sx, which now depends on spec/signals.sx.

Updated all load paths:
- hosts/ocaml/bin/sx_server.ml — loads spec/signals.sx before web/signals.sx
- hosts/ocaml/bin/run_tests.ml — loads both in order
- hosts/ocaml/browser/bundle.sh + sx-platform.js — loads core-signals.sx first
- shared/sx/ocaml_bridge.py — loads spec/signals.sx before web extensions

1116/1116 OCaml tests pass. Browser reactive island preview works.

b1690a92c4 Add SX test harness: mock IO platform for testing components
spec/harness.sx — spec-level test harness with:
- Mock platform (30+ default IO mocks: fetch, query, DOM, storage, etc.)
- Session management (make-harness, harness-reset!, harness-set!/get)
- IO interception (make-interceptor, install-interceptors)
- IO log queries (io-calls, io-call-count, io-call-nth, io-call-args)
- IO assertions (assert-io-called, assert-no-io, assert-io-count, etc.)

15 harness tests passing on both OCaml (1116/1116) and JS (15/15).
Loaded automatically by both test runners.

MCP tool: sx_harness_eval — evaluate SX with mock IO, returns result + IO trace.

The harness is extensible: new platforms just add entries to the platform dict.
Components can ship with deftest forms that verify IO behavior against mocks.
Tests are independent objects that can be published separately (by CID).

76ce0c3ecb Add 15 new MCP tools to sx-tree: project-wide search, smart editing, dev workflow
New comprehension tools:
- sx_find_across: search pattern across all .sx files in a directory
- sx_comp_list: list all definitions (defcomp/defisland/defmacro/defpage/define)
- sx_comp_usage: find all uses of a component across files
- sx_diff: structural diff between two .sx files (ADDED/REMOVED/CHANGED)
- sx_eval: REPL — evaluate SX expressions in the MCP server env

Smart read_tree enhancements:
- Auto-summarise large files (>200 lines)
- focus param: expand only matching subtrees, collapse rest
- max_depth/max_lines/offset for depth limiting and pagination

Smart editing tools:
- sx_rename_symbol: rename all occurrences of a symbol in a file
- sx_replace_by_pattern: find+replace first/all pattern matches
- sx_insert_near: insert before/after a pattern match (top-level)
- sx_rename_across: rename symbol across all .sx files (with dry_run)
- sx_write_file: create .sx files with parse validation

Development tools:
- sx_pretty_print: reformat .sx files with indentation (also used by all edit tools)
- sx_build: build JS bundle or OCaml binary
- sx_test: run test suites with structured pass/fail results
- sx_format_check: lint for empty bindings, missing bodies, duplicate params
- sx_macroexpand: evaluate expressions with a file's macro definitions loaded

Also: updated hook to block Write on .sx files, added custom explore agent.

3559ce44f2 Add named path navigation: "defisland > let > letrec" resolves to index path
Named paths let you navigate by structure name instead of opaque indices.
Both formats work in all MCP tools:
  - Index: "(0 3 2)"
  - Named: "defisland > let > letrec"

The server detects ">" in the path string and calls resolve-named-path
(SX function) which walks the tree matching child names at each level.

New SX functions: resolve-named-path, split-path-string, find-child-by-name.
MCP server: added trim/split primitives, resolve_path dispatcher.

63babc0d2d Add render tab to tree editor, switch MCP paths to SX format
Tree editor island now has 4 tabs: tree, context, validate, render.
The render tab evaluates SX source as live HTML — type a (div (h2 "Hello"))
and see it rendered immediately.

MCP server paths changed from JSON arrays [0,2,1] to SX strings "(0 2 1)".
Fixes serialization issues and is more natural for an SX tool. The
json_to_path function now parses SX via sx-parse.

6d0e512f19 Add interactive tree editor island (Phase 4) + MCP server fixes
Phase 4: defisland ~sx-tools/tree-editor — interactive tree viewer
embedded in the SX Tools page. Features:
- Textarea with :bind for SX source input
- Parse button to re-parse on demand
- Tree view: annotated tree with path labels, clickable nodes
- Context view: enclosing chain from root to selected node
- Validate view: structural integrity checks (catches missing body etc.)

MCP server fixes: added ident-start?, ident-char?, make-keyword,
escape-string, sx-expr-source — needed by parser.sx when loaded
into the MCP evaluator.

Also: .mcp.json for Claude Code MCP server config, CLAUDE.md protocol
for structural .sx file editing.

934604c2bd Add SX tree tools: comprehension, editing, and MCP server
Phase 1-3 of the SX Tools plan — structural reading, editing, and
MCP server for .sx files.

lib/tree-tools.sx — Pure SX functions for tree comprehension and editing:
  Comprehension: annotate-tree, summarise, read-subtree, get-context,
    find-all, get-siblings, validate, navigate
  Editing: replace-node, insert-child, delete-node, wrap-node, tree-set
  Helpers: list-replace, list-insert, list-remove, replace-placeholder

lib/tests/test-tree-tools.sx — 107 tests covering all functions.

hosts/ocaml/bin/mcp_tree.ml — MCP server (stdio JSON-RPC) exposing
  11 tools. Loads tree-tools.sx into the OCaml evaluator, parses .sx
  files with the native parser, calls SX functions for tree operations.

The MCP server can be configured in Claude Code's settings.json as:
  "mcpServers": { "sx-tree": { "command": "path/to/mcp_tree.exe" } }

1429 tests passing (1322 existing + 107 new tree-tools).

43cf590541 Expand JIT closure tests: nested, mutual recursion, set!, island, deep
22 JIT closure scoping tests covering:
- Basic closure var in map callback + context switch
- Signal + letrec + map (stepper pattern)
- Nested closures (inner lambda sees outer let var)
- Mutual recursion in letrec (is-even/is-odd)
- set! mutation of closure var after JIT compilation
- defisland with signal + letrec + map
- Deep nesting (for-each inside map inside letrec inside let)

All test the critical invariant: JIT-compiled lambdas must use
their closure's vm_env_ref, not the caller's globals.

57e7ce9fe4 Add JIT closure scoping tests
Tests the exact pattern that broke the home stepper: a component
with letrec bindings referenced inside a map callback. The JIT
compiles the callback with closure vars merged into vm_env_ref.
Subsequent renders must use that env, not the caller's globals.

7 tests covering:
- letrec closure var in map callback (fmt function)
- Render, unrelated render, re-render (env not polluted)
- Signal + letrec + map (the stepper pattern)

759309c5c4 Fix create-text-node on server: return string instead of nil
Server-side create-text-node was returning Nil, causing imperative
text nodes (stopwatch "Start"/"0.0s", imperative counter "0") to
render as empty in SSR HTML. Now returns the text as a String value,
which render-to-html handles via escape-html.

f3f70cc00b Move stdlib out of spec — clean spec/library boundary
spec/ now contains only the language definition (5 files):
  evaluator.sx, parser.sx, primitives.sx, render.sx, special-forms.sx

lib/ contains code written IN the language (8 files):
  stdlib.sx, types.sx, freeze.sx, content.sx,
  bytecode.sx, compiler.sx, vm.sx, callcc.sx

Test files follow source: spec/tests/ for core language tests,
lib/tests/ for library tests (continuations, freeze, types, vm).

Updated all consumers:
- JS/Python/OCaml bootstrappers: added lib/ to source search paths
- OCaml bridge: spec_dir for parser/render, lib_dir for compiler/freeze
- JS test runner: scans spec/tests/ (always) + lib/tests/ (--full)
- OCaml test runner: scans spec/tests/, lib tests via explicit request
- Docker dev mounts: added ./lib:/app/lib:ro

Tests: 1041 JS standard, 1322 JS full, 1101 OCaml — all pass
