-WS()

-Defines the WebSocket message handler for the current `.ws.uce` page.
-
-The same page may expose both `RENDER()` and `WS()`. `RENDER()` serves the initial HTTP response, while `WS()` is called whenever a complete WebSocket message arrives for that page.
-
-UCE reassembles fragmented messages before calling `WS()`. Text and binary frames are both delivered. Use `ws_opcode()` and `ws_is_binary()` to distinguish them.
-
-The `call` parameter passed into `WS()` contains:
-
-- `message`
-- `connection_id`
-- `scope`
-- `opcode`
-- `document_uri`

+RENDER(Request& context)
+

+Defines the main HTTP render handler for the current `.uce` page.
+
+When a page is requested over HTTP, the runtime loads the target file and calls its `RENDER(Request& context)` function.
+
+Pages may also export additional named render handlers with `RENDER:NAME(Request& context)`.
+
+Named render handlers are not used for the page's direct HTTP entrypoint. They are intended for component-style sub-rendering through helpers such as `component("components/card:BODY", props, context)` or `render_component("components/card:BODY", props, context)`.
+
+The default page entrypoint is always the plain `RENDER(Request& context)` handler.
+
+The request environment is passed explicitly through `context`, including params, cookies, post data, session state, headers, uploaded files, and the current `context.call` tree.
+
+For a normal direct page request, `context.call` starts empty.
+
+If the page is invoked from another UCE file via `render_file(file_name, context)`, the callee receives that same `context`.
+
+Pages intended to serve WebSocket traffic may expose both `RENDER(Request& context)` and `WS(Request& context)`. In that case `RENDER(Request& context)` serves the initial HTTP response and `WS(Request& context)` handles subsequent WebSocket messages.

+UCE source preprocessing
+
+:desc
+UCE runs a small custom source-to-source preprocessor before Clang sees a `.uce` or `.ws.uce` file.
+
+The implementation lives in `src/lib/compiler.cpp`. It does not try to parse all of C++. Instead, it performs a narrow character-wise rewrite that understands UCE literal blocks, inline code islands, `#load`, and `EXPORT` harvesting, then writes a generated `.cpp` file and compiles that file into a shared object.
+
+:Syntax
+- `<> ... </>` enters literal-output mode.
+- Inside a literal block, `<? ... ?>` emits raw C++.
+- Inside a literal block, `<?= expression ?>` emits `print(html_escape(expression));`.
+- Inside a literal block, `<?: expression ?>` emits `print(expression);` without HTML escaping.
+- `#load "other.uce"` injects another UCE unit at compile time.
+- `RENDER(Request& context)` and `WS(Request& context)` are normal C++ macros from `src/lib/compiler.h`.
+- `EXPORT` is also a normal C++ macro, but the custom pass additionally records exported declarations for metadata.
+
+:Pipeline
+- The generated file starts by including `COMPILER_SYS_PATH/src/lib/uce_lib.h`.
+- It then inlines the configured setup template from `SETUP_TEMPLATE` (by default `scripts/setup.h.template`), which defines `set_current_request(Request*)`.
+- It inserts `#line 1` before page code so compiler diagnostics point back to the original `.uce` file.
+- Each literal block is rewritten into one or more `print(R"( ... )");` calls.
+- `<? ... ?>` temporarily breaks out of literal printing, emits the enclosed C++ unchanged, then resumes literal output.
+- `<?= ... ?>` becomes `print(html_escape(...));`. The runtime currently provides `html_escape()` overloads for `String`, `u64`, and `f64`.
+- `<?: ... ?>` becomes `print(...);` and is intended for trusted markup or already-escaped content.
+- `#load "file.uce"` is replaced with a generated C++ `#include` that points at the loaded unit's preprocessed `.cpp` file under `BIN_DIRECTORY`.
+- Lines beginning with `EXPORT` are scanned so their declarations can be written to a sibling `.exports.txt` file.
+- The final generated source is written to `BIN_DIRECTORY + src_path + "/" + source_file + ".cpp"`.
+- `scripts/compile` then compiles that generated `.cpp` into `source_file + ".so"` with `clang++ -shared -std=c++20 ...`.
+
+:GeneratedFiles
+- Source file: `/some/path/page.uce`
+- Generated C++: `BIN_DIRECTORY/some/path/page.uce.cpp`
+- Shared object: `BIN_DIRECTORY/some/path/page.uce.so`
+- Export list: `BIN_DIRECTORY/some/path/page.uce.exports.txt`
+
+:Example
+Example 1: literal output with escaped data
+`RENDER(Request& context)`
+`{`
+`    &lt;&gt;&lt;h1&gt;&lt;?= context.params["DOCUMENT_URI"] ?&gt;&lt;/h1&gt;&lt;/&gt;`
+`}`
+
+Roughly becomes:
+`print(R"(&lt;h1&gt;)");`
+`print(html_escape(context.params["DOCUMENT_URI"]));`
+`print(R"(&lt;/h1&gt;)");`
+
+Example 1b: literal output with trusted unescaped markup
+`RENDER(Request& context)`
+`{`
+`    &lt;&gt;&lt;div class="panel"&gt;&lt;?: component("components/card", context.call, context) ?&gt;&lt;/div&gt;&lt;/&gt;`
+`}`
+
+Roughly becomes:
+`print(R"(&lt;div class="panel"&gt;)");`
+`print(component("components/card", context.call, context));`
+`print(R"(&lt;/div&gt;)");`
+
+Example 2: compile-time composition
+`#load "partials/nav.uce"`
+`RENDER(Request& context)`
+`{`
+`    &lt;&gt;&lt;body&gt;...&lt;/body&gt;&lt;/&gt;`
+`}`
+
+The loaded file is resolved relative to the current source file unless the path is already absolute.
+
+:Rules
+- Literal mode starts only on the exact token `<>`.
+- Literal mode ends only on the exact token `</>`.
+- `#load` is recognized only when the current line starts with `#load ` at column 1.
+- `EXPORT` harvesting likewise only triggers when the current line starts with `EXPORT` at column 1 and is followed by whitespace.
+- Relative `#load` paths are expanded against the including unit's source directory.
+- `render_file()` and `call_file()` are runtime APIs; `#load` is a compile-time include/composition feature.
+
+:Limitations
+- This pass is character-wise, not a full parser.
+- Outside literal blocks it only tracks double-quoted C++ strings while deciding whether `<>` should open literal mode.
+- It does not understand comments, raw string literals, templates, or general C++ token structure.
+- Inside literal blocks it tracks single and double quotes while scanning a `<? ... ?>` island so quoted `?>` text does not close the island early.
+- Literal blocks are not nested.
+- Because literal output is emitted as a C++ raw string literal `R"( ... )"`, literal content must not contain the exact terminator sequence `)"` or the generated C++ will break.
+- `#load` depends on the target unit's generated `.cpp` existing and being compilable. If the target cannot be preprocessed or compiled correctly, the including file will fail to compile as well.
+
+:Debugging
+- When a page is compiled, inspect the generated file under `BIN_DIRECTORY` first. That file shows the exact C++ produced by the UCE preprocessor.
+- Compiler errors usually point back to the `.uce` source because the preprocessor inserts `#line 1`, but the generated `.cpp` is still the best place to inspect expansion problems.
+- If a `#load` include looks wrong, check the current file's directory, the configured `BIN_DIRECTORY`, and whether the loaded page already produced its own generated `.cpp`.

+
+`options["allow_html"]`

+When true, raw HTML blocks and inline tags may pass through as `raw_html` nodes instead of being escaped as plain text.
+
+`options["components"]`
+Declares renderer extension points using normal UCE components.
+
+Exact directive hooks:
+`options["components"][":::warning"] = "components/markdown/warning"`
+This hook is selected for `:::warning ... :::` blocks.
+
+Generic node hooks:
+`options["components"]["node.code_block"] = "components/markdown/code_block"`
+`options["components"]["node.table"] = "components/markdown/table"`
+`options["components"]["node.link"] = "components/markdown/link"`
+`options["components"]["node.directive"] = "components/markdown/directive"`
+
+If both an exact directive hook and a generic `node.directive` hook exist, the exact directive hook wins.
+
+:ComponentProps
+When a markdown hook component is called, its props arrive in `context.call`.
+
+Useful fields include:
+`context.call["hook"]` : matched hook key such as `:::warning` or `node.code_block`
+`context.call["target"]` : resolved component target name
+`context.call["default_html"]` : renderer output without the hook
+`context.call["children_html"]` : already-rendered child HTML
+`context.call["node"]` : full AST node
+`context.call["type"]` : node type
+`context.call["name"]` : directive name when applicable
+`context.call["argument"]` : directive remainder after the name
+`context.call["text"]` : source text for nodes such as `code_block`
+`context.call["lang"]` : fenced code language
+`context.call["href"]` / `context.call["src"]` / `context.call["title"]`
+`context.call["options"]` : full markdown options tree
+
+This lets a component either replace the HTML completely or wrap `default_html` / `children_html`.
+
+:DirectiveSchema
+Directive blocks use this form:
+`:::warning title="Heads up"`
+`Body markdown here`
+`:::`
+
+The parser stores:
+`node["name"] = "warning"`
+`node["argument"] = ...` for bare trailing text
+`node["attrs"] = ...` for parsed `key=value` pairs such as `title="Heads up"`
+
+This makes directive components a good fit for alerts, callouts, cards, embeds, and any richer page-level markdown extension.
