New language feature: (cyst [:key id] body...) creates a DOM container
with its own island scope that persists across parent reactive re-renders.
On first render, the body is evaluated in a fresh with-island-scope and
the resulting DOM is cached. On subsequent renders, the cached DOM node
is returned if still connected to the document.
This solves the fundamental problem of nesting reactive islands inside
other islands' render trees — the child island's DOM (with its event
handlers and signal subscriptions) survives when the parent re-renders.
Implementation: *memo-cache* dict keyed by cyst id. render-dom checks
isConnected before returning cached node. Each cyst gets its own
disposer list via with-island-scope.
Usage in sx-tools: defisland render preview now wrapped in (cyst :key
full-name ...). Real mouse clicks work — counter increments, temperature
converts, computed signals update. Verified on both local and live site.

- Removed auto-parse on source change (the (reset! parsed ...) at top
of letrec body). Only Parse button triggers parsing now.
- Split defcomp/defisland render: defcomp uses parameter substitution
with bindings signal, defisland uses live component call.
- Removed stopPropagation wrapper (didn't help).
Island previews are reactive — signals, computed, swap! all work.
Known: Playwright's click (which triggers focus change from textarea)
resets the island. Direct JS clicks and PointerEvent dispatches work
correctly. Real islands on demo pages work perfectly with mouse clicks.

The island preview refactoring replaced both defcomp and defisland
handling with sx-load-components + component call. This broke parameter
substitution for defcomp (which uses bindings signal for live preview).
Split the cond: defcomp uses the original subst approach (extract params,
read bindings, substitute symbols in body). defisland uses the live
preview via sx-load-components + native render-dom-island.

- render-html-island wraps body SSR in cek-try (graceful fallback to
empty container when island body has DOM/signal code)
- defcomp placeholder pattern: server renders safe placeholder div
with data-sx-island, browser hydrates the actual island
- cek-try primitive added to both server and browser OCaml kernels
- assert/assert= added to spec/harness.sx for standalone use
- Test source stored in <script type="text/sx-test" data-for="...">
with HTML entity decoding via host-call replaceAll
Temperature converter: 5 tests embedded in demo page. Test runner
hydrates and finds tests but body render is empty — needs debugging
of the specific construct that silently fails in render-to-dom.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

defisland expressions are now rendered as fully reactive live previews.
The component is registered via sx-load-components, then called through
the native render-dom-island adapter path — same code path as real
islands on the page.
Bare (deref sig) expressions are fully reactive — clicking buttons
updates signal values and DOM updates in real time. Compound expressions
like (str (deref c) "°C") render statically (cek-reactive-text only
tracks bare deref). Next: auto-wrap deref-containing expressions in
computed signals for full reactive expression support.
Also cleaned up stale effect and preview-el signal from earlier attempts.

defisland expressions in the render tab are now evaluated through
render-to-dom inside with-island-scope, producing real DOM with signal
bindings. The rendered output persists in a stable container managed by
an effect, outside the reactive render tree.
Known limitation: signal subscriptions don't fire on button clicks yet —
the reactive wiring needs investigation into how deferred (setTimeout)
execution contexts interact with CEK signal tracking. Static rendering
(initial values) works correctly.
Also: removed stale effect that attempted hydrate-island approach.

sx->hypersx transform converts parsed SX to a readable indentation-based
format: CSS selector shorthand (div.card#main), signal sugar (@count,
signal(), :=, <-), string interpolation ("Count: {@count}"), and
structural keywords (when, if, let, map, for).
Implemented as pure SX in web/lib/hypersx.sx, loaded in browser via
js_of_ocaml platform. Added as "hypersx" tab in the tree editor.

Register cond-scheme? as OCaml primitive — was defined in spec/evaluator.sx
but never exposed to the browser runtime, causing render.sx to crash with
"Undefined symbol: cond-scheme?" on every SX response. This broke URL
updates on navigation (handle-history never ran after the rendering error).
Tree editor render tab now extracts &key params from defcomp/defisland
definitions and shows input fields. Values substitute into the rendered
preview live as you type. Inputs live outside the reactive cond branch
so signal updates don't steal focus.
sx-tools page function accepts &key params (title, etc.) forwarded to
the overview component.

The render tab now correctly renders HTML tag expressions as live DOM
(div, h2, p, ul, etc. with Tailwind classes). Non-HTML expressions
(defcomp, define, etc.) are shown as serialized SX text.
Previous version tried eval-expr which errored silently in the browser.

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.

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.

Two bugs caused code blocks to render empty across the site:
1. ~docs/code component had parameter named `code` which collided with
the HTML <code> tag name. Renamed to `src` and updated all 57
callers. Added font-mono class for explicit monospace.
2. Batched IO dispatch in ocaml_bridge.py only skipped one leading
number (batch ID) but the format has two (epoch + ID):
(io-request EPOCH ID "name" args...). Changed to skip all leading
numbers so the string name is correctly found. This fixes highlight
and other batchable helpers returning empty results.

Two paren bugs in home-stepper.sx caused the home page to render blank:
1. Line 222 had one extra ) that prematurely closed the letrec bindings
list — rebuild-preview and do-back became body expressions instead
of bindings, making them undefined in scope.
2. Lines 241-308 were outside the let/letrec scope entirely — the outer
let closed at line 240, so freeze-scope, cookie restore, source
parsing, and the entire div rendering tree had no access to signals
or letrec functions.
Also hardens defisland to wrap multi-expression bodies in (begin ...),
matching the Python-side fix from 9f0c541. Both spec/evaluator.sx and
the OCaml transpiled sx_ref.ml are updated.
Adds SX Tools essay under Applications — the revised plan for structural
tree reading/editing tools for .sx files, motivated by this exact bug.

When the VM called a JIT-compiled lambda, it passed vm.globals
(the caller's global env) instead of cl.vm_env_ref (the closure's
captured env that was merged at compile time). Closure-captured
variables like code-tokens from island let/letrec scopes were
invisible at runtime, causing "Undefined symbol" errors that
cascaded to disable render-to-html globally.
Fix: call_closure uses cl.vm_env_ref at both call sites (cached
bytecode and fresh compilation).

Server-rendered dashboard showing live data from sx-pub API:
- Server status (DB, IPFS, actor, domain)
- Actor identity card with public key
- Collections grid with paths
- Published documents with CIDs and sizes

New endpoints:
- POST /pub/anchor — batch unanchored Publish activities into Merkle tree,
pin tree to IPFS, submit root to OpenTimestamps, store OTS proof on IPFS
- GET /pub/verify/<cid> — verify a CID's Merkle proof against anchored tree
Uses existing shared/utils/anchoring.py infrastructure:
- build_merkle_tree (SHA256, deterministic sort)
- get_merkle_proof / verify_merkle_proof (inclusion proofs)
- submit_to_opentimestamps (3 calendar servers with fallback)
Tested: anchored 1 activity, Merkle tree + OTS proof pinned to IPFS,
verification returns :verified true with full proof chain.

- POST /pub/inbox — receive Follow/Accept/Publish from remote servers
- POST /pub/follow — follow a remote sx-pub server
- GET /pub/followers — list accepted followers
- GET /pub/following — list who we follow
Federation mechanics:
- HTTP Signature generation (RSA-SHA256) for signed outgoing requests
- HTTP Signature verification for incoming requests
- Auto-accept Follow → store follower → send Accept back
- Accept handling → update following state
- Publish mirroring → pin remote CID to local IPFS
- deliver_to_followers → fan out signed activities to all follower inboxes
- Publish now records activity in outbox for federation delivery

Three issues in the stepper island's client-side rendering:
1. do-step used eval-expr with empty env for ~cssx/tw spreads — component
not found, result leaked as [object Object]. Fixed: call ~cssx/tw
directly (in scope from island env) with trampoline.
2. steps-to-preview excluded spreads — SSR preview had no styling.
Fixed: include spreads in the tree so both SSR and client render
with CSSX classes.
3. build-children used named let (let loop ...) which produces
unresolved Thunks in render mode due to the named-let compiler
desugaring interacting with the render/eval boundary. Fixed:
rewrote as plain recursive function bc-loop avoiding named let.

Three bugs broke island SSR rendering of the home stepper widget:
1. Inline VM opcodes (OP_ADD..OP_DEC) broke JIT-compiled functions.
The compiler emitted single-byte opcodes for first/rest/len/= etc.
that produced wrong results in complex recursive code (sx-parse
returned nil, split-tag produced 1 step instead of 16). Reverted
compiler to use CALL_PRIM for all primitives. VM opcode handlers
kept for future use.
2. Named let (let loop ((x init)) body) had no compiler support —
silently produced broken bytecode. Added desugaring to letrec.
3. URL-encoded cookie values not decoded server-side. Client set-cookie
uses encodeURIComponent but Werkzeug doesn't decode cookie values.
Added unquote() in bridge cookie injection.
Also: call-lambda used eval_expr which copies Dict values (signals),
breaking mutations through aser lambda calls. Switched to cek_call.
Also: stepper preview now includes ~cssx/tw spreads for SSR styling.

Removes the 5993-line bootstrapped Python evaluator (sx_ref.py) and all
code that depended on it exclusively. Both bootstrappers (JS + OCaml)
now use a new synchronous OCaml bridge (ocaml_sync.py) to run the
transpiler. JS build produces identical output; OCaml bootstrap produces
byte-identical sx_ref.ml.
Key changes:
- New shared/sx/ocaml_sync.py: sync subprocess bridge to sx_server.exe
- hosts/javascript/bootstrap.py: serialize defines → temp file → OCaml eval
- hosts/ocaml/bootstrap.py: same pattern for OCaml transpiler
- shared/sx/{html,async_eval,resolver,jinja_bridge,handlers,pages,deps,helpers}:
stub or remove sx_ref imports; runtime uses OCaml bridge (SX_USE_OCAML=1)
- sx/sxc/pages: parse defpage/defhandler from AST instead of Python eval
- hosts/ocaml/lib/sx_primitives.ml: append handles non-list 2nd arg per spec
- Deleted: sx_ref.py, async_eval_ref.py, 6 Python test runners, misc ref/ files
Test results: JS 1078/1078, OCaml 1114/1114.

dom.sx and browser.sx are library source (not transpiled into the bundle),

steps-to-preview is a pure recursive descent function inside the island's
letrec that builds an SX expression tree from steps[0..target-1].
The preview lake uses it to show partial text (e.g. "the joy of " at step 9).
Still WIP: stepper island doesn't SSR because DOM-only code (effect,
dom-query, dom-create-element) runs in the island body and fails on server.
Need to guard client-only code so SSR can render the pure parts
(code view, counter, preview).

get-cookie / set-cookie primitives on both server and client:
- JS: reads/writes document.cookie
- OCaml: get-cookie reads from _request_cookies hashtable,
set-cookie is no-op (server sets cookies via HTTP headers)
- Python bridge: _inject_request_cookies_locked() sends
(set-request-cookies {:name "val"}) to kernel before page render
Stepper island (home-stepper.sx):
- Persistence switched from localStorage to cookie (sx-home-stepper)
- freeze-scope/thaw-from-sx mechanism preserved, just different storage
- Server reads cookie → thaw restores step-idx → SSR renders correct step
- Code highlighting: removed imperative code-spans/build-code-dom/
update-code-highlight; replaced with live DOM query that survives morphs
- Removed code-view lake wrapper (now plain reactive DOM)

The OOB layout delegates to ~shared:layout/oob-sx which needs to
produce sx-swap-oob elements. Without server affinity, the aser
serializes the component call for client-side rendering (matching
production behaviour where the client renders the OOB structure).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.

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.

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.
