-# Code style
-All code is done with 2 spaces for indentation.
+# ƿit (pit) Language Project
 
-For cell script and its integration files, objects are preferred over classes, and preferrably limited use of prototypes, make objects sendable between actors (.ce files).
+## Building
 
-## cell script format
-Cell script files end in .ce or .cm. Cell script is similar to Javascript but with some differences.
+Build (or rebuild after changes): `make`
+Install to system: `make install`
+Run `cell --help` to see all CLI flags.
 
-Variables are delcared with 'var'. Var behaves like let.
-Constants are declared with 'def'.
-!= and == are strict, there is no !== or ===.
-There is no undefined, only null.
-There are no classes, only objects and prototypes.
-Prefer backticks for string interpolation. Otherwise, convering non strings with the text() function is required.
-Everything should be lowercase.
+## Code Style
 
-There are no arraybuffers, only blobs, which work with bits. They must be stoned like stone(blob) before being read from.
+All code uses 2 spaces for indentation. K&R style for C and Javascript.
 
-## c format
-For cell script integration files, everything should be declared static that can be. Most don't have headers at all. Files in a package are not shared between packages.
+## ƿit Script Quick Reference
 
-There is no undefined, so JS_IsNull and JS_NULL should be used only.
+ƿit script files: `.ce` (actors) and `.cm` (modules). The syntax is similar to JavaScript with important differences listed below.
 
-## how module loading is done in cell script
-Within a package, a c file, if using the correct macros (CELL_USE_FUNCS etc), will be loaded as a module with its name; so png.c inside ac package is loaded as <package>/png, giving you access to its functions.
+### Key Differences from JavaScript
+
+- `var` (mutable) and `def` (constant) — no `let` or `const`
+- `==` and `!=` are strict (no `===` or `!==`)
+- No `undefined` — only `null`
+- No classes — only objects and prototypes (`meme()`, `proto()`, `isa()`)
+- No `switch`/`case` — use record dispatch (a record keyed by case, values are functions or results) instead of if/else chains
+- No `for...in`, `for...of`, spread (`...`), rest params, or default params
+- Functions have a maximum of 4 parameters — use a record for more
+- Variables must be declared at function body level only (not in if/while/for/blocks)
+- All variables must be initialized at declaration (`var x` alone is an error; use `var x = null`)
+- No `try`/`catch`/`throw` — use `disrupt`/`disruption`
+- No arraybuffers — only `blob` (works with bits; must `stone(blob)` before reading)
+- Identifiers can contain `?` and `!` (e.g., `nil?`, `set!`, `is?valid`)
+- Prefer backticks for string interpolation; otherwise use `text()` to convert non-strings
+- Everything should be lowercase
+
+### Intrinsic Functions (always available, no `use()` needed)
+
+The creator functions are **polymorphic** — behavior depends on argument types:
+
+- `array(number)` — create array of size N filled with null
+- `array(number, value_or_fn)` — create array with initial values
+- `array(array)` — copy array
+- `array(array, fn)` — map
+- `array(array, array)` — concatenate
+- `array(array, from, to)` — slice
+- `array(record)` — get keys as array of text
+- **`array(text)` — split text into individual characters** (e.g., `array("hello")` → `["h","e","l","l","o"]`)
+- `array(text, separator)` — split by separator
+- `array(text, length)` — split into chunks of length
+
+- `text(array, separator)` — join array into text
+- `text(number)` or `text(number, radix)` — number to text
+- `text(text, from, to)` — substring
+
+- `number(text)` or `number(text, radix)` — parse text to number
+- `number(logical)` — boolean to number
+
+- `record(record)` — copy
+- `record(record, another)` — merge
+- `record(array_of_keys)` — create record from keys
+
+Other key intrinsics: `length()`, `stone()`, `is_stone()`, `print()`, `filter()`, `find()`, `reduce()`, `sort()`, `reverse()`, `some()`, `every()`, `starts_with()`, `ends_with()`, `meme()`, `proto()`, `isa()`, `splat()`, `apply()`, `extract()`, `replace()`, `search()`, `format()`, `lower()`, `upper()`, `trim()`
+
+Sensory functions: `is_array()`, `is_text()`, `is_number()`, `is_object()`, `is_function()`, `is_null()`, `is_logical()`, `is_integer()`, `is_stone()`, etc.
+
+### Standard Library (loaded with `use()`)
+
+- `blob` — binary data (bits, not bytes)
+- `time` — time constants and conversions
+- `math` — trig, logarithms, roots (`math/radians`, `math/turns`)
+- `json` — JSON encoding/decoding
+- `random` — random number generation
+
+### Actor Model
+
+- `.ce` files are actors (independent execution units, don't return values)
+- `.cm` files are modules (return a value, cached and frozen)
+- Actors never share memory; communicate via `$send()` message passing
+- Actor intrinsics start with `$`: `$me`, `$stop()`, `$send()`, `$start()`, `$delay()`, `$receiver()`, `$clock()`, `$portal()`, `$contact()`, `$couple()`, `$unneeded()`, `$connection()`, `$time_limit()`
+
+### Requestors (async composition)
+
+`sequence()`, `parallel()`, `race()`, `fallback()` — compose asynchronous operations. See docs/requestors.md.
+
+### Error Handling
+
+```javascript
+var fn = function() {
+  disrupt  // bare keyword, no value
+} disruption {
+  // handle error; can re-raise with disrupt
+}
+```
+
+### Push/Pop Syntax
+
+```javascript
+var a = [1, 2]
+a[] = 3       // push: [1, 2, 3]
+var v = a[]   // pop: v is 3, a is [1, 2]
+```
+
+## C Integration
+
+- Declare everything `static` that can be
+- Most files don't have headers; files in a package are not shared between packages
+- No undefined in C API: use `JS_IsNull` and `JS_NULL` only
+- A C file with correct macros (`CELL_USE_FUNCS` etc) is loaded as a module by its name (e.g., `png.c` in a package → `use('<package>/png')`)
+- C symbol naming: `js_<pkg>_<file>_use` (e.g., `js_core_math_radians_use` for `core/math/radians`)
+- Core is the `core` package — its symbols follow the same `js_core_<name>_use` pattern as all other packages
+- Package directories should contain only source files (no `.mach`/`.mcode` alongside source)
+- Build cache files in `build/` are bare hashes (no extensions)
+
+### MANDATORY: GC Rooting for C Functions
+
+This project uses a **copying garbage collector**. ANY JS allocation (`JS_NewObject`, `JS_NewString`, `JS_NewArray`, `JS_NewInt32`, `JS_SetPropertyStr`, `js_new_blob_stoned_copy`, etc.) can trigger GC, which **invalidates all unrooted JSValue locals**. This is not theoretical — it causes real crashes.
+
+**Before writing or modifying ANY C function**, apply this checklist:
+
+1. Count the number of `JS_New*`, `JS_SetProperty*`, and `js_new_blob*` calls in the function
+2. If there are 2 or more, the function MUST use `JS_FRAME`/`JS_ROOT`/`JS_RETURN`
+3. Every JSValue that is held across an allocating call must be rooted
+
+**Pattern — object with properties:**
+```c
+JS_FRAME(js);
+JS_ROOT(obj, JS_NewObject(js));
+JS_SetPropertyStr(js, obj.val, "x", JS_NewInt32(js, 42));
+JS_SetPropertyStr(js, obj.val, "name", JS_NewString(js, "hello"));
+JS_RETURN(obj.val);
+```
+
+**Pattern — array with loop:**
+```c
+JS_FRAME(js);
+JS_ROOT(arr, JS_NewArray(js));
+for (int i = 0; i < count; i++) {
+  JS_ROOT(item, JS_NewObject(js));
+  JS_SetPropertyStr(js, item.val, "v", JS_NewInt32(js, i));
+  JS_SetPropertyNumber(js, arr.val, i, item.val);
+}
+JS_RETURN(arr.val);
+```
+
+**Rules:**
+- Access rooted values via `.val` (e.g., `obj.val`, not `obj`)
+- Error returns before `JS_FRAME` use plain `return`
+- Error returns after `JS_FRAME` must use `JS_RETURN_EX()` or `JS_RETURN_NULL()`
+- When calling a helper that itself returns a JSValue, that return value is safe to pass directly into `JS_SetPropertyStr` — no need to root temporaries that aren't stored in a local
+
+**Common mistake — UNSAFE (will crash under GC pressure):**
+```c
+JSValue obj = JS_NewObject(js);  // NOT rooted
+JS_SetPropertyStr(js, obj, "pixels", js_new_blob_stoned_copy(js, data, len));
+// ^^^ blob allocation can GC, invalidating obj
+return obj;  // obj may be a dangling pointer
+```
+
+See `docs/c-modules.md` for the full GC safety reference.
+
+## Project Layout
+
+- `source/` — C source for the cell runtime and CLI
+- `docs/` — master documentation (Markdown), reflected on the website
+- `website/` — Hugo site; theme at `website/themes/knr/`
+- `internal/` — internal ƿit scripts (engine.cm etc.)
+- `packages/` — core packages
+- `Makefile` — build system (`make` to rebuild, `make bootstrap` for first build)
+
+## Package Management (Shop CLI)
+
+When running locally with `./cell --dev`, these commands manage packages:
+
+```
+./cell --dev add <path>                    # add a package (local path or remote)
+./cell --dev remove <path>                 # remove a package (cleans lock, symlink, dylibs)
+./cell --dev build <path>                  # build C modules for a package
+./cell --dev test package <path>           # run tests for a package
+./cell --dev list                          # list installed packages
+```
+
+Local paths are symlinked into `.cell/packages/`. The build step compiles C files to content-addressed dylibs in `~/.cell/build/<hash>` and writes a per-package manifest so the runtime can find them. C files in `src/` are support files linked into module dylibs, not standalone modules.
+
+## Debugging Compiler Issues
+
+When investigating bugs in compiled output (wrong values, missing operations, incorrect comparisons), **start from the optimizer down, not the VM up**. The compiler inspection tools will usually identify the problem faster than adding C-level tracing:
+
+```
+./cell --dev streamline --types <file>    # show inferred slot types — look for wrong types
+./cell --dev ir_report --events <file>    # show every optimization applied and why
+./cell --dev ir_report --types <file>     # show type inference results per function
+./cell --dev mcode --pretty <file>        # show raw IR before optimization
+./cell --dev streamline --ir <file>       # show human-readable optimized IR
+```
+
+**Triage order:**
+1. `streamline --types` — are slot types correct? Wrong type inference causes wrong optimizations.
+2. `ir_report --events` — are type checks being incorrectly eliminated? Look for `known_type_eliminates_guard` on slots that shouldn't have known types.
+3. `mcode --pretty` — is the raw IR correct before optimization? If so, the bug is in streamline.
+4. Only dig into `source/mach.c` if the IR looks correct at all levels.
+
+See `docs/compiler-tools.md` for the full tool reference and `docs/spec/streamline.md` for pass details.
+
+## Testing
+
+After any C runtime changes, run all three test suites before considering the work done:
+
+```
+make                        # rebuild
+./cell --dev vm_suite       # VM-level tests (641 tests)
+./cell --dev test suite     # language-level tests (493 tests)
+./cell --dev fuzz           # fuzzer (100 iterations)
+```
+
+All three must pass with 0 failures.
+
+## Documentation
+
+The `docs/` folder is the single source of truth. The website at `website/` mounts it via Hugo. Key files:
+- `docs/language.md` — language syntax reference
+- `docs/functions.md` — all built-in intrinsic functions
+- `docs/actors.md` — actor model and actor intrinsics
+- `docs/requestors.md` — async requestor pattern
+- `docs/library/*.md` — intrinsic type reference (text, number, array, object) and standard library modules

+// boot_miscompile_bad.cm — Documents a boot compiler miscompilation bug.
+//
+// BUG SUMMARY:
+// The boot compiler's optimizer (likely compress_slots, eliminate_moves,
+// or infer_param_types) miscompiles a specific pattern when it appears
+// inside streamline.cm. The pattern: an array-loaded value used as a
+// dynamic index for another array store, inside a guarded block:
+//
+//   sv = instr[j]
+//   if (is_number(sv) && sv >= 0 && sv < nr_slots) {
+//     last_ref[sv] = i    // <-- miscompiled: sv reads wrong slot
+//   }
+//
+// The bug is CONTEXT-DEPENDENT on streamline.cm's exact function/closure
+// structure. A standalone module with the same pattern does NOT trigger it.
+// The boot optimizer's cross-function analysis (infer_param_types, type
+// propagation, etc.) makes different decisions in the full streamline.cm
+// context, leading to the miscompilation.
+//
+// SYMPTOMS:
+// - 'log' is not defined  (comparison error path fires on non-comparable values)
+// - array index must be a number  (store_dynamic with corrupted index)
+// - Error line has NO reference to 'log' — the reference comes from the
+//   error-reporting code path of the < operator
+// - Non-deterministic: different error messages on different runs
+// - NOT a GC bug: persists with --heap 4GB
+// - NOT slot overflow: function has only 85 raw slots
+//
+// TO REPRODUCE:
+// In streamline.cm, replace the build_slot_liveness function body with
+// this version (raw operand scanning instead of get_slot_refs):
+//
+//   var build_slot_liveness = function(instructions, nr_slots) {
+//     var last_ref = array(nr_slots, -1)
+//     var n = length(instructions)
+//     var i = 0
+//     var j = 0
+//     var limit = 0
+//     var sv = 0
+//     var instr = null
+//
+//     while (i < n) {
+//       instr = instructions[i]
+//       if (is_array(instr)) {
+//         j = 1
+//         limit = length(instr) - 2
+//         while (j < limit) {
+//           sv = instr[j]
+//           if (is_number(sv) && sv >= 0 && sv < nr_slots) {
+//             last_ref[sv] = i
+//           }
+//           j = j + 1
+//         }
+//       }
+//       i = i + 1
+//     }
+//     return last_ref
+//   }
+//
+// Then: rm -rf .cell/build && ./cell --dev vm_suite
+//
+// WORKAROUND:
+// Use get_slot_refs(instr) to iterate only over known slot-reference
+// positions. This produces different IR that the boot optimizer handles
+// correctly, and is also more semantically correct.
+//
+// FIXING:
+// To find the root cause, compare the boot-compiled bytecodes of
+// build_slot_liveness (in the full streamline.cm context) vs the
+// source-compiled bytecodes. Use disasm.ce with --optimized to see
+// what the source compiler produces. The boot-compiled bytecodes
+// would need a C-level MachCode dump to inspect.

+
+ƿit is an actor-based scripting language for building concurrent applications. It combines a familiar C-like syntax with the actor model of computation, optimized for low memory usage and simplicity.
+
+## Key Features
+
+- **Actor Model** — isolated memory, message passing, no shared state
+- **Immutability** — `stone()` makes values permanently frozen
+- **Prototype Inheritance** — objects without classes
+- **C Integration** — seamlessly extend with native code
+- **Cross-Platform** — deploy to desktop, web, and embedded
+
+## Quick Start
+
+```javascript
+// hello.ce - A simple actor
+print("Hello, ƿit!")
+$stop()
+```
+
+```bash
+pit hello
+```
+
+## Language
+
+- [**ƿit Language**](/docs/language/) — syntax, types, and operators
+- [**Actors and Modules**](/docs/actors/) — the execution model
+- [**Requestors**](/docs/requestors/) — asynchronous composition
+- [**Packages**](/docs/packages/) — code organization and sharing
+- [**Shop Architecture**](/docs/shop/) — module resolution, compilation, and caching
+
+## Reference
+
+- [**Built-in Functions**](/docs/functions/) — intrinsics reference
+- [text](/docs/library/text/) — text conversion and manipulation
+- [number](/docs/library/number/) — numeric conversion and operations
+- [array](/docs/library/array/) — array creation and manipulation
+- [object](/docs/library/object/) — object creation, prototypes, and serialization
+
+## Standard Library
+
+Modules loaded with `use()`:
+
+- [blob](/docs/library/blob/) — binary data
+- [time](/docs/library/time/) — time and dates
+- [math](/docs/library/math/) — trigonometry and math
+- [json](/docs/library/json/) — JSON encoding/decoding
+- [random](/docs/library/random/) — random numbers
+
+## Tools
+
+- [**Command Line**](/docs/cli/) — the `pit` tool
+- [**Semantic Index**](/docs/semantic-index/) — index and query symbols, references, and call sites
+- [**Testing**](/docs/testing/) — writing and running tests
+- [**Compiler Inspection**](/docs/compiler-tools/) — dump AST, mcode, and optimizer reports
+- [**Writing C Modules**](/docs/c-modules/) — native extensions
+
+## Architecture
+
+ƿit programs are organized into **packages**. Each package contains:
+
+- **Modules** (`.cm`) — return a value, cached and frozen
+- **Actors** (`.ce`) — run independently, communicate via messages
+- **C files** (`.c`) — compiled to native libraries
+
+Actors never share memory. They communicate by sending messages, which are automatically serialized. This makes concurrent programming safe and predictable.
+
+## Installation
+
+```bash
+# Clone and bootstrap
+git clone https://gitea.pockle.world/john/cell
+cd cell
+make bootstrap
+```
+
+The ƿit shop is stored at `~/.cell/`.
+
+## Development
+
+After making changes, recompile with:
+
+```bash
+make
+```
+
+Run `cell --help` to see all available CLI flags.

 Actors have access to special functions prefixed with `$`:
 
-### $me
+### $self
 
-Reference to the current actor.
+Reference to the current actor. This is a stone (immutable) actor object.
 
 ```javascript
-log.console($me)  // actor reference
+print($self)            // actor reference
+print(is_actor($self))  // true
+```
+
+### $overling
+
+Reference to the parent actor that started this actor. `null` for the root actor. Child actors are automatically coupled to their overling — if the parent dies, the child dies too.
+
+```javascript
+if ($overling != null) {
+  send($overling, {status: "ready"})
+}
 ```
 
 ### $stop()
 
-Stop the current actor.
+Stop the current actor. When called with an actor argument, stops that underling (child) instead.
 
 ```javascript
-$stop()
+$stop()          // stop self
+$stop(child)     // stop a child actor
 ```
 
-### $send(actor, message, callback)
-
-Send a message to another actor.
+**Important:** `$stop()` does not halt execution immediately. Code after the call continues running in the current turn — it only prevents the actor from receiving future messages. Structure your code so that nothing runs after `$stop()`, or use `return` to exit the current function first.
 
 ```javascript
-$send(other_actor, {type: "ping", data: 42}, function(reply) {
-  log.console("Got reply:", reply)
-})
-```
+// Wrong — code after $stop() still runs
+if (done) $stop()
+do_more_work()  // this still executes!
 
-Messages are automatically **splatted** — flattened to plain data without prototypes.
+// Right — return after $stop()
+if (done) { $stop(); return }
+do_more_work()
+```
 
 ### $start(callback, program)
 
-Start a new actor from a script.
+Start a new child actor from a script. The callback receives lifecycle events:
+
+- `{type: "greet", actor: <ref>}` — child started successfully
+- `{type: "stop"}` — child stopped cleanly
+- `{type: "disrupt", reason: ...}` — child crashed
 
 ```javascript
-$start(function(new_actor) {
-  log.console("Started:", new_actor)
+$start(function(event) {
+  if (event.type == 'greet') {
+    print("Child started:", event.actor)
+    send(event.actor, {task: "work"})
+  }
+  if (event.type == 'stop') {
+    print("Child stopped")
+  }
+  if (event.type == 'disrupt') {
+    print("Child crashed:", event.reason)
+  }
 }, "worker")
 ```
 
 ### $delay(callback, seconds)
 
-Schedule a callback after a delay.
+Schedule a callback after a delay. Returns a cancel function that can be called to prevent the callback from firing.
 
 ```javascript
-$delay(function() {
-  log.console("5 seconds later")
+var cancel = $delay(function() {
+  print("5 seconds later")
 }, 5)
+
+// To cancel before it fires:
+cancel()
 ```
 
 ### $clock(callback)
 
-Get called every frame/tick.
+Get called every frame/tick. The callback receives the current time as a number.
 
 ```javascript
-$clock(function(dt) {
-  // Called each tick with delta time
+$clock(function(t) {
+  // called each tick with current time
 })
 ```
 
 ### $receiver(callback)
 
-Set up a message receiver.
+Set up a message receiver. The callback is called with the incoming message whenever another actor sends a message to this actor.
+
+To reply to a message, call `send(message, reply_data)` — the message object contains routing information that directs the reply back to the sender.
 
 ```javascript
-$receiver(function(message, reply) {
-  // Handle incoming message
-  reply({status: "ok"})
+$receiver(function(message) {
+  // handle incoming message
+  send(message, {status: "ok"})
 })
 ```
 
 ### $portal(callback, port)
 
-Open a network port.
+Open a network port to receive connections from remote actors.
 
 ```javascript
 $portal(function(connection) {
-  // Handle new connection
+  // handle new connection
 }, 8080)
 ```
 
 ### $contact(callback, record)
 
-Connect to a remote address.
+Connect to a remote actor at a given address.
 
 ```javascript
 $contact(function(connection) {
-  // Connected
+  // connected
 }, {host: "example.com", port: 80})
 ```
 
 ### $time_limit(requestor, seconds)
 
-Wrap a requestor with a timeout.
+Wrap a requestor with a timeout. Returns a new requestor that will cancel the original and call its callback with a failure if the time limit is exceeded. See [Requestors](/docs/requestors/) for details.
 
 ```javascript
-$time_limit(my_requestor, 10)  // 10 second timeout
+var timed = $time_limit(my_requestor, 10)
+
+timed(function(result, reason) {
+  // reason will explain timeout if it fires
+}, initial_value)
 ```
 
+### $couple(actor)
+
+Couple the current actor to another actor. When the coupled actor dies, the current actor also dies. Coupling is automatic between a child actor and its overling (parent).
+
+```javascript
+$couple(other_actor)
+```
+
+### $unneeded(callback, seconds)
+
+Schedule the actor for removal after a specified time. The callback fires when the time elapses.
+
+```javascript
+$unneeded(function() {
+  // cleanup before removal
+}, 30)
+```
+
+### $connection(callback, actor, config)
+
+Get information about the connection to another actor. For local actors, returns `{type: "local"}`. For remote actors, returns connection details including latency, bandwidth, and activity.
+
+```javascript
+$connection(function(info) {
+  if (info.type == "local") {
+    print("same machine")
+  } else {
+    print(info.latency)
+  }
+}, other_actor, {})
+```
+
+## Runtime Functions
+
+These functions are available in actors without the `$` prefix:
+
+### send(actor, message, callback)
+
+Send a message to another actor. The message must be an object record.
+
+The optional callback receives the reply when the recipient responds.
+
+```javascript
+send(other_actor, {type: "ping"}, function(reply) {
+  print("Got reply:", reply)
+})
+```
+
+To reply to a received message, pass the message itself as the first argument — it contains routing information:
+
+```javascript
+$receiver(function(message) {
+  send(message, {result: 42})
+})
+```
+
+Messages are automatically flattened to plain data.
+
+### is_actor(value)
+
+Returns `true` if the value is an actor reference.
+
+```javascript
+if (is_actor(some_value)) {
+  send(some_value, {ping: true})
+}
+```
+
+### log
+
+Channel-based logging. Any `log.X(value)` writes to channel `"X"`. Three channels are conventional: `log.console(msg)`, `log.error(msg)`, `log.system(msg)` — but any name works.
+
+Channels are routed to configurable **sinks** (console or file) defined in `.cell/log.toml`. See [Logging](/docs/logging/) for the full guide.
+
+### use(path)
+
+Import a module. See [Module Resolution](#module-resolution) below.
+
+### args
+
+Array of command-line arguments passed to the actor.
+
+### sequence(), parallel(), race(), fallback()
+
+Requestor composition functions. See [Requestors](/docs/requestors/) for details.

-```

-}
-

-```
-
 ## Build Process
 
 C files are automatically compiled when you run:
 
 ```bash
-cell build
-cell update
+cell --dev build
 ```
 
-The resulting dynamic library is placed in `~/.cell/lib/`.
+Each C file is compiled into a per-file dynamic library at a content-addressed path in `~/.cell/build/<hash>`. A manifest is written for each package so the runtime can find dylibs without rerunning the build pipeline — see [Dylib Manifests](/docs/shop/#dylib-manifests).
+
+## Compilation Flags (cell.toml)
+
+Use the `[compilation]` section in `cell.toml` to pass compiler and linker flags:
+
+```toml
+[compilation]
+CFLAGS = "-Isrc -Ivendor/include"
+LDFLAGS = "-lz -lm"
+```
+
+### Include paths
+
+Relative `-I` paths are resolved from the package root:
+
+```toml
+CFLAGS = "-Isdk/public"
+```
+
+If your package is at `/path/to/mypkg`, this becomes `-I/path/to/mypkg/sdk/public`.
+
+Absolute paths are passed through unchanged.
+
+The build system also auto-discovers `include/` directories — if your package has an `include/` directory, it is automatically added to the include path. No need to add `-I$PACKAGE/include` in cell.toml.
+
+### Library paths
+
+Relative `-L` paths work the same way:
+
+```toml
+LDFLAGS = "-Lsdk/lib -lmylib"
+```
+
+### Target-specific flags
+
+Add sections named `[compilation.<target>]` for platform-specific flags:
+
+```toml
+[compilation]
+CFLAGS = "-Isdk/public"
+
+[compilation.macos_arm64]
+LDFLAGS = "-Lsdk/lib/osx -lmylib"
+
+[compilation.linux]
+LDFLAGS = "-Lsdk/lib/linux64 -lmylib"
+
+[compilation.windows]
+LDFLAGS = "-Lsdk/lib/win64 -lmylib64"
+```
+
+Available targets: `macos_arm64`, `macos_x86_64`, `linux`, `linux_arm64`, `windows`.
+
+### Sigils
+
+Use sigils in flags to refer to standard directories:
+
+- `$LOCAL` — absolute path to `.cell/local` (for prebuilt libraries)
+- `$PACKAGE` — absolute path to the package root
+
+```toml
+CFLAGS = "-I$PACKAGE/vendor/include"
+LDFLAGS = "-L$LOCAL -lmyprebuilt"
+```
+
+### Example: vendored SDK
+

+
+## Multi-File C Modules
+
+If your module wraps a C library, place the library's source files in a `src/` directory. Files in `src/` are compiled as support objects and linked into your module's dylib — they are not treated as standalone modules.
+
+```
+mypackage/
+  rtree.c       # module (exports js_mypackage_rtree_use)
+  src/
+    rtree.c      # support file (linked into rtree.dylib)
+    rtree.h      # header
+```
+
+The module file (`rtree.c`) includes the library header and uses `cell.h` as usual. The support files are plain C — they don't need any cell macros.
+
+## GC Safety
+
+ƿit uses a **Cheney copying garbage collector**. Any JS allocation — `JS_NewObject`, `JS_NewString`, `JS_NewInt32`, `JS_SetPropertyStr`, `js_new_blob_stoned_copy`, etc. — can trigger GC, which **moves** heap objects to new addresses. Bare C locals holding `JSValue` become **dangling pointers** after any allocating call. This is not a theoretical concern — it causes real crashes that are difficult to reproduce because they depend on heap pressure.
+
+### Checklist (apply to EVERY C function you write or modify)
+
+1. Count the `JS_New*`, `JS_SetProperty*`, and `js_new_blob*` calls in the function
+2. If there are **2 or more**, the function **MUST** use `JS_FRAME` / `JS_ROOT` / `JS_RETURN`
+3. Every `JSValue` held in a C local across an allocating call must be rooted
+
+### When you need rooting
+
+If a function creates **one** heap object and returns it immediately, no rooting is needed:
+
+```c
+JSC_CCALL(mymod_name,
+  ret = JS_NewString(js, "hello");
+)
+```
+
+If a function creates an object and then sets properties on it, you **must** root it — each `JS_SetPropertyStr` call is an allocating call that can trigger GC:
+
+```c
+// UNSAFE — will crash under GC pressure:
+JSValue obj = JS_NewObject(js);
+JS_SetPropertyStr(js, obj, "x", JS_NewInt32(js, 1));  // can GC → obj is stale
+JS_SetPropertyStr(js, obj, "y", JS_NewInt32(js, 2));  // obj may be garbage
+return obj;
+
+// SAFE:
+JS_FRAME(js);
+JS_ROOT(obj, JS_NewObject(js));
+JS_SetPropertyStr(js, obj.val, "x", JS_NewInt32(js, 1));
+JS_SetPropertyStr(js, obj.val, "y", JS_NewInt32(js, 2));
+JS_RETURN(obj.val);
+```
+
+### Patterns
+
+**Object with properties** — the most common pattern in this codebase:
+
+```c
+JS_FRAME(js);
+JS_ROOT(result, JS_NewObject(js));
+JS_SetPropertyStr(js, result.val, "width", JS_NewInt32(js, w));
+JS_SetPropertyStr(js, result.val, "height", JS_NewInt32(js, h));
+JS_SetPropertyStr(js, result.val, "pixels", js_new_blob_stoned_copy(js, data, len));
+JS_RETURN(result.val);
+```
+
+**Array with loop** — root the element variable *before* the loop, then reassign `.val` each iteration:
+
+```c
+JS_FRAME(js);
+JS_ROOT(arr, JS_NewArray(js));
+JS_ROOT(item, JS_NULL);
+for (int i = 0; i < count; i++) {
+  item.val = JS_NewObject(js);
+  JS_SetPropertyStr(js, item.val, "index", JS_NewInt32(js, i));
+  JS_SetPropertyStr(js, item.val, "data", js_new_blob_stoned_copy(js, ptr, sz));
+  JS_SetPropertyNumber(js, arr.val, i, item.val);
+}
+JS_RETURN(arr.val);
+```
+
+**WARNING — NEVER put `JS_ROOT` inside a loop.** `JS_ROOT` declares a `JSGCRef` local and calls `JS_PushGCRef(&name)`, which pushes its address onto a linked list. Inside a loop the compiler reuses the same stack address, so on iteration 2+ the list becomes self-referential (`ref->prev == ref`). When GC triggers it walks the chain and **hangs forever**. This bug is intermittent — it only manifests when GC happens to run during the loop — making it very hard to reproduce.
+
+**Nested objects** — root every object that persists across an allocating call:
+
+```c
+JS_FRAME(js);
+JS_ROOT(outer, JS_NewObject(js));
+JS_ROOT(inner, JS_NewArray(js));
+// ... populate inner ...
+JS_SetPropertyStr(js, outer.val, "items", inner.val);
+JS_RETURN(outer.val);
+```
+
+**Inside `JSC_CCALL`** — use `JS_RestoreFrame` and assign to `ret`:
+
+```c
+JSC_CCALL(mymod_make,
+  JS_FRAME(js);
+  JS_ROOT(obj, JS_NewObject(js));
+  JS_SetPropertyStr(js, obj.val, "x", number2js(js, 42));
+  JS_RestoreFrame(_js_ctx, _js_gc_frame, _js_local_frame);
+  ret = obj.val;
+)
+```
+
+### Macros
+
+| Macro | Purpose |
+|-------|---------|
+| `JS_FRAME(js)` | Save the GC frame. Required before any `JS_ROOT`. |
+| `JS_ROOT(name, init)` | Declare a `JSGCRef` and root its value. Access via `name.val`. |
+| `JS_LOCAL(name, init)` | Declare a rooted `JSValue` (GC updates it through its address). |
+| `JS_RETURN(val)` | Restore the frame and return a value. |
+| `JS_RETURN_NULL()` | Restore the frame and return `JS_NULL`. |
+| `JS_RETURN_EX()` | Restore the frame and return `JS_EXCEPTION`. |
+| `JS_RestoreFrame(...)` | Manual frame restore (for `JSC_CCALL` bodies that use `ret =`). |
+
+### Error return rules
+
+- Error returns **before** `JS_FRAME` can use plain `return JS_ThrowTypeError(...)` etc.
+- Error returns **after** `JS_FRAME` must use `JS_RETURN_EX()` or `JS_RETURN_NULL()` — never plain `return`, which would leak the GC frame.
+
+### Migrating from gc_mark
+
+The old mark-and-sweep GC had a `gc_mark` callback in `JSClassDef` for C structs that held JSValue fields. This no longer exists. The copying GC needs to know the **address** of every pointer to update it when objects move.
+
+If your C struct holds a JSValue that must survive across GC points, root it for the duration it's alive:
+
+```c
+typedef struct {
+  JSValue callback;
+  JSLocalRef callback_lr;
+} MyWidget;
+
+// When storing:
+widget->callback = value;
+widget->callback_lr.ptr = &widget->callback;
+JS_PushLocalRef(js, &widget->callback_lr);
+
+// When done (before freeing the struct):
+// The local ref is cleaned up when the frame is restored,
+// or manage it manually.
+```
+
+In practice, most C wrappers hold only opaque C pointers (like `SDL_Window*`) and never store JSValues in the struct — these need no migration.

+
+## Troubleshooting
+
+### Missing header / SDK not installed
+
+If a package wraps a third-party SDK that isn't installed on your system, the build will show:
+
+```
+module.c: fatal error: 'sdk/header.h' file not found (SDK not installed?)
+```
+
+Install the required SDK or skip that package. These warnings are harmless — other packages continue building normally.
+
+### CFLAGS not applied
+
+If your `cell.toml` has a `[compilation]` section but flags aren't being picked up, check:
+
+1. The TOML syntax is valid (strings must be quoted)
+2. The section header is exactly `[compilation]` (not `[compile]` etc.)
+3. Target-specific sections use valid target names: `macos_arm64`, `macos_x86_64`, `linux`, `linux_arm64`, `windows`
+
+### API changes from older versions
+
+If C modules fail with errors about function signatures:
+
+- `JS_IsArray` takes one argument (the value), not two — remove the context argument
+- Use `JS_GetPropertyNumber` / `JS_SetPropertyNumber` instead of `JS_GetPropertyUint32` / `JS_SetPropertyUint32`
+- Use `JS_NewString` instead of `JS_NewAtomString`
+- There is no `undefined` — use `JS_IsNull` and `JS_NULL` only

-# Cell Language
-
-Cell is a scripting language for actor-based programming. It combines a familiar syntax with a prototype-based object system and strict immutability semantics.
-
-## Basics
-
-### Variables and Constants
-
-```javascript
-var x = 10        // mutable variable (block-scoped like let)
-def PI = 3.14159  // constant (cannot be reassigned)
-```
-
-### Data Types
-
-Cell has six fundamental types:
-
-- **number** — DEC64 decimal floating point (no rounding errors)
-- **text** — Unicode strings
-- **logical** — `true` or `false`
-- **null** — the absence of a value (no `undefined`)
-- **array** — ordered, numerically-indexed sequences
-- **object** — key-value records with prototype inheritance
-- **blob** — binary data (bits, not bytes)
-- **function** — first-class callable values
-
-### Literals
-
-```javascript
-// Numbers
-42
-3.14
-1_000_000        // underscores for readability
-
-// Text
-"hello"
-'world'
-`template ${x}`  // string interpolation
-
-// Logical
-true
-false
-
-// Null
-null
-
-// Arrays
-[1, 2, 3]
-["a", "b", "c"]
-
-// Objects
-{name: "cell", version: 1}
-{x: 10, y: 20}
-```
-
-### Operators
-
-```javascript
-// Arithmetic
-+ - * / %
-**              // exponentiation
-
-// Comparison (always strict)
-==              // equals (like === in JS)
-!=              // not equals (like !== in JS)
-< > <= >=
-
-// Logical
-&& || !
-
-// Assignment
-= += -= *= /=
-```
-
-### Control Flow
-
-```javascript
-// Conditionals
-if (x > 0) {
-  log.console("positive")
-} else if (x < 0) {
-  log.console("negative")
-} else {
-  log.console("zero")
-}
-
-// Ternary
-var sign = x > 0 ? 1 : -1
-
-// Loops
-for (var i = 0; i < 10; i++) {
-  log.console(i)
-}
-
-for (var item of items) {
-  log.console(item)
-}
-
-for (var key in obj) {
-  log.console(key, obj[key])
-}
-
-while (condition) {
-  // body
-}
-
-// Control
-break
-continue
-return value
-throw "error message"
-```
-
-### Functions
-
-```javascript
-// Named function
-function add(a, b) {
-  return a + b
-}
-
-// Anonymous function
-var multiply = function(a, b) {
-  return a * b
-}
-
-// Arrow function
-var square = x => x * x
-var sum = (a, b) => a + b
-
-// Rest parameters
-function log_all(...args) {
-  for (var arg of args) log.console(arg)
-}
-
-// Default parameters
-function greet(name, greeting = "Hello") {
-  return `${greeting}, ${name}!`
-}
-```
-
-All closures capture `this` (like arrow functions in JavaScript).
-
-## Arrays
-
-Arrays are **distinct from objects**. They are ordered, numerically-indexed sequences. You cannot add arbitrary string keys to an array.
-
-```javascript
-var arr = [1, 2, 3]
-arr[0]              // 1
-arr[2] = 10         // [1, 2, 10]
-length(arr)         // 3
-
-// Array spread
-var more = [...arr, 4, 5]  // [1, 2, 10, 4, 5]
-```
-
-## Objects
-
-Objects are key-value records with prototype-based inheritance.
-
-```javascript
-var point = {x: 10, y: 20}
-point.x             // 10
-point["y"]          // 20
-
-// Object spread
-var point3d = {...point, z: 30}
-
-// Prototype inheritance
-var colored_point = {__proto__: point, color: "red"}
-colored_point.x     // 10 (inherited)
-```
-
-### Prototypes
-
-```javascript
-// Create object with prototype
-var child = meme(parent)
-
-// Get prototype
-var p = proto(child)
-
-// Check prototype chain
-isa(child, parent)  // true
-```
-
-## Immutability with Stone
-
-The `stone()` function makes values permanently immutable.
-
-```javascript
-var config = stone({
-  debug: true,
-  maxRetries: 3
-})
-
-config.debug = false  // Error! Stone objects cannot be modified
-```
-
-Stone is **deep** — all nested objects and arrays are also frozen. This cannot be reversed.
-
-```javascript
-stone.p(value)  // returns true if value is stone
-```
-
-## Built-in Functions
-
-### length(value)
-
-Returns the length of arrays (elements), text (codepoints), blobs (bits), or functions (arity).
-
-```javascript
-length([1, 2, 3])      // 3
-length("hello")        // 5
-length(function(a,b){}) // 2
-```
-
-### use(path)
-
-Import a module. Returns the cached, stone value.
-
-```javascript
-var math = use('math/radians')
-var json = use('json')
-```
-
-### isa(value, type)
-
-Check type or prototype chain.
-

-## Running Scripts
+## Package Commands
 
-Any `.ce` file in the Cell core can be run as a command:
+These commands operate on a package's `cell.toml`, source files, or build artifacts.
+
+### pit add
+
+Add a dependency to the current package. Installs the package to the shop, builds any C modules, and updates `cell.toml`.
 
 ```bash
-cell version    # runs version.ce
-cell build      # runs build.ce
-cell test       # runs test.ce
+pit add gitea.pockle.world/john/prosperon         # remote, default alias
+pit add gitea.pockle.world/john/prosperon myalias  # remote, custom alias
+pit add /Users/john/work/mylib                     # local path (symlinked)
+pit add .                                          # current directory
+pit add ../sibling-package                         # relative path
+```
+
+For local paths, the package is symlinked into the shop rather than copied. Changes to the source directory are immediately visible.
+
+### pit build
+
+Build C modules for a package. Compiles each C file into a per-file dynamic library stored in the content-addressed build cache at `~/.cell/build/<hash>`. A per-package manifest is written so the runtime can find dylibs by package name. C files in `src/` directories are compiled as support objects and linked into the module dylibs. Files that previously failed to compile are skipped automatically (cached failure markers); they are retried when the source or compiler flags change.
+
+```bash
+pit build                         # build all packages
+pit build <package>               # build specific package
+pit build /Users/john/work/mylib  # build local package
+pit build .                       # build current directory
+pit build -t macos_arm64          # cross-compile for target
+pit build -b debug                # build type: release (default), debug, minsize
+pit build --list-targets          # list available targets
+pit build --force                 # force rebuild
+pit build --dry-run               # show what would be built
+pit build --verbose               # print resolved flags, commands, cache status
+```
+
+### pit test
+
+Run tests. See [Testing](/docs/testing/) for the full guide.
+
+```bash
+pit test                                   # run tests in current package
+pit test suite                             # run specific test file
+pit test all                               # run all tests in current package
+pit test package <name>                    # run tests in a named package
+pit test package /Users/john/work/mylib    # run tests for a local package
+pit test package all                       # run tests from all packages
+pit test suite --verify --diff             # with IR verification and differential testing
+```
+
+### pit ls
+
+List modules and actors in a package.
+
+```bash
+pit ls              # list files in current project
+pit ls <package>    # list files in specified package
+```
+
+### pit audit
+
+Test-compile all `.ce` and `.cm` scripts in package(s). Continues past failures and reports all errors at the end.
+
+```bash
+pit audit               # audit all installed packages
+pit audit <package>     # audit specific package
+pit audit .             # audit current directory
+```
+
+### pit resolve
+
+Print the fully resolved dependency closure for a package.
+
+```bash
+pit resolve              # resolve current package
+pit resolve <package>    # resolve specific package
+pit resolve --locked     # show lock state without links
+```
+
+### pit graph
+
+Emit a dependency graph.
+
+```bash
+pit graph                      # tree of current package
+pit graph --format dot         # graphviz dot output
+pit graph --format json        # json output
+pit graph --world              # graph all installed packages
+pit graph --locked             # show lock view without links
+```
+
+### pit verify
+

+pit verify --deep       # traverse full dependency closure
+pit verify --target <triple>
+```
+
+### pit pack
+
+Build a statically linked binary from a package and all its dependencies.
+
+```bash
+pit pack <package>              # build static binary (output: app)
+pit pack <package> -o myapp     # specify output name
+pit pack <package> -t <triple>  # cross-compile for target
+```
+
+### pit config
+
+Manage system and actor configuration values in `cell.toml`.
+
+```bash
+pit config list                          # list all config
+pit config get system.ar_timer           # get a value
+pit config set system.ar_timer 5.0       # set a value
+pit config actor <name> list             # list actor config
+pit config actor <name> get <key>        # get actor config
+pit config actor <name> set <key> <val>  # set actor config
+```
+
+### pit bench
+
+Run benchmarks with statistical analysis. Benchmark files are `.cm` modules in a package's `benches/` directory.
+
+```bash
+pit bench                          # run all benchmarks in current package
+pit bench all                      # same as above

+```
+
+## Developer Commands
+
+Compiler pipeline tools, analysis, and testing. These are primarily useful for developing the ƿit compiler and runtime.
+
+### Compiler Pipeline
+
+Each of these commands runs the compilation pipeline up to a specific stage and prints the intermediate output. They take a source file as input.
+
+### pit tokenize
+
+Tokenize a source file and output the token stream as JSON.
+
+```bash
+pit tokenize <file.cm>
+```
+
+### pit parse
+
+Parse a source file and output the AST as JSON.
+
+```bash
+pit parse <file.cm>
+```
+
+### pit fold
+
+Run constant folding and semantic analysis on a source file and output the simplified AST as JSON.
+
+```bash
+pit fold <file.cm>
+```
+
+### pit mcode
+
+Compile a source file to mcode (machine-independent intermediate representation) and output as JSON.
+
+```bash
+pit mcode <file.cm>
+```
+
+### pit streamline
+
+Apply the full optimization pipeline to a source file and output optimized mcode as JSON.
+
+```bash
+pit streamline <file.cm>                # full optimized IR as JSON (default)
+pit streamline --stats <file.cm>        # summary stats per function
+pit streamline --ir <file.cm>           # human-readable IR
+pit streamline --check <file.cm>        # warnings only (e.g. high slot count)
+```
+
+Flags can be combined. `--stats` output includes function name, args, slots, instruction counts by category, and nops eliminated. `--check` warns when `nr_slots > 200` (approaching the 255 limit).
+
+### pit qbe
+
+Compile a source file to QBE intermediate language (for native code generation).
+
+```bash
+pit qbe <file.cm>
+```
+
+### pit compile
+
+Compile a source file to a native dynamic library.
+
+```bash
+pit compile <file.cm>    # outputs .dylib to ~/.cell/build/
+pit compile <file.ce>
+```
+
+### pit run_native
+
+Compile a module natively and compare execution against interpreted mode, showing timing differences.
+
+```bash
+pit run_native <module>              # compare interpreted vs native
+pit run_native <module> <test_arg>   # pass argument to module function
+```
+
+### pit run_aot
+
+Ahead-of-time compile and execute a program natively.
+
+```bash
+pit run_aot <program.ce>
+```
+
+### pit seed
+
+Regenerate the boot seed files in `boot/`. Seeds are pre-compiled mcode IR (JSON) that bootstrap the compilation pipeline on cold start. They only need regenerating when the pipeline source changes in a way the existing seeds can't compile, or before distribution.
+
+```bash
+pit seed                # regenerate all boot seeds
+pit seed --clean        # also clear the build cache after
+```
+
+The engine recompiles pipeline modules automatically when source changes (via content-addressed cache). Seeds are a fallback for cold start when no cache exists.
+
+### Analysis
+
+### pit explain
+
+Query the semantic index for symbol information at a specific source location or by name.
+
+```bash
+pit explain --span <file:line:col>       # find symbol at position
+pit explain --symbol <name> [files...]   # find symbol by name
+pit explain --help                       # show usage
+```
+
+### pit index
+
+Build a semantic index for a source file and output symbol information as JSON.
+
+```bash
+pit index <file.cm>                # output to stdout
+pit index <file.cm> -o index.json  # output to file
+pit index --help                   # show usage
+```
+
+### pit ir_report
+
+Optimizer flight recorder — capture detailed information about IR transformations during optimization.
+
+```bash
+pit ir_report <file.cm>                  # per-pass JSON summaries (default)
+pit ir_report <file.cm> --events         # include rewrite events
+pit ir_report <file.cm> --types          # include type deltas
+pit ir_report <file.cm> --ir-before=PASS # print IR before specific pass
+pit ir_report <file.cm> --ir-after=PASS  # print IR after specific pass
+pit ir_report <file.cm> --ir-all         # print IR before/after every pass
+pit ir_report <file.cm> --full           # all options combined
+```
+
+Output is NDJSON (newline-delimited JSON).
+
+### Testing
+
+### pit diff
+
+Differential testing — run tests with and without optimizations and compare results.
+
+```bash
+pit diff                # diff all test files in current package
+pit diff <suite>        # diff specific test file
+pit diff tests/<path>   # diff by path
+```
+
+### pit fuzz
+
+Random program fuzzer — generates random programs and checks for optimization correctness by comparing optimized vs unoptimized execution.
+
+```bash
+pit fuzz                       # 100 iterations with random seed
+pit fuzz <iterations>          # specific number of iterations
+pit fuzz --seed <N>            # start at specific seed
+pit fuzz <iterations> --seed <N>
+```
+
+Failures are saved to `tests/fuzz_failures/`.
+
+### pit vm_suite
+
+Run the VM stability test suite (641 tests covering arithmetic, strings, control flow, closures, objects, and more).
+
+```bash
+pit vm_suite
+```
+
+### pit syntax_suite
+
+Run the syntax feature test suite (covers all literal types, operators, control flow, functions, prototypes, and more).
+
+```bash
+pit syntax_suite
 ```

+description: "Tools for inspecting and debugging the compiler pipeline"
+weight: 50
+type: "docs"
+---
+
+ƿit includes a set of tools for inspecting the compiler pipeline at every stage. These are useful for debugging, testing optimizations, and understanding what the compiler does with your code.
+
+## Pipeline Overview
+
+The compiler runs in stages:
+
+```
+source → tokenize → parse → fold → mcode → streamline → output
+```
+
+Each stage has a corresponding CLI tool that lets you see its output.
+
+| Stage       | Tool                      | What it shows                          |
+|-------------|---------------------------|----------------------------------------|
+| tokenize    | `tokenize.ce`             | Token stream as JSON                   |
+| parse       | `parse.ce`                | Unfolded AST as JSON                   |

+
+## Quick Start
+
+```bash
+# see raw mcode IR (pretty-printed)
+cell mcode --pretty myfile.ce
+
+# source-interleaved disassembly
+cell disasm myfile.ce
+
+# see optimized IR with type annotations
+cell streamline --types myfile.ce
+
+# full optimizer report with events
+cell ir_report --full myfile.ce
+```
+
+## fold.ce
+
+Prints the folded AST as JSON. This is the output of the parser and constant folder, before mcode generation.
+
+```bash
+cell fold <file.ce|file.cm>
+```
+
+## mcode.ce
+
+Prints mcode IR. Default output is JSON; use `--pretty` for human-readable format with opcodes, operands, and program counter.
+
+```bash
+cell mcode <file.ce|file.cm>            # JSON (default)
+cell mcode --pretty <file.ce|file.cm>   # human-readable IR
+```
+
+## streamline.ce
+
+Runs the full pipeline (tokenize, parse, fold, mcode, streamline) and outputs the optimized IR as JSON. Useful for piping to `jq` or saving for comparison.
+
+```bash
+cell streamline <file.ce|file.cm>                # full JSON (default)
+cell streamline --stats <file.ce|file.cm>        # summary stats per function
+cell streamline --ir <file.ce|file.cm>           # human-readable IR
+cell streamline --check <file.ce|file.cm>        # warnings only
+cell streamline --types <file.ce|file.cm>        # IR with type annotations
+cell streamline --diagnose <file.ce|file.cm>     # compile-time diagnostics
+```
+
+| Flag | Description |
+|------|-------------|
+| (none) | Full optimized IR as JSON (backward compatible) |
+| `--stats` | Per-function summary: args, slots, instruction counts by category, nops eliminated |
+| `--ir` | Human-readable canonical IR (same format as `ir_report.ce`) |
+| `--check` | Warnings only (e.g. `nr_slots > 200` approaching 255 limit) |
+| `--types` | Optimized IR with inferred type annotations per slot |
+| `--diagnose` | Run compile-time diagnostics (type errors and warnings) |
+
+Flags can be combined.
+
+## disasm.ce
+
+Source-interleaved disassembly. Shows mcode or optimized IR with source lines interleaved, making it easy to see which instructions were generated from which source code.
+
+```bash
+cell disasm <file>                         # disassemble all functions (mcode)
+cell disasm --optimized <file>             # disassemble optimized IR (streamline)
+cell disasm --fn 87 <file>                 # show only function 87
+cell disasm --fn my_func <file>            # show only functions named "my_func"
+cell disasm --line 235 <file>              # show instructions generated from line 235
+```
+
+| Flag | Description |
+|------|-------------|
+| (none) | Raw mcode IR with source interleaving (default) |
+| `--optimized` | Use optimized IR (streamline) instead of raw mcode |
+| `--fn <N\|name>` | Filter to specific function by index or name substring |
+| `--line <N>` | Show only instructions generated from a specific source line |
+
+### Output Format
+
+Functions are shown with a header including argument count, slot count, and the source line where the function begins. Instructions are grouped by source line, with the source text shown before each group:
+
+```
+=== [87] <anonymous> (args=0, slots=12, closures=0) [line 234] ===
+
+  --- line 235: var result = compute(x, y) ---
+  0     access         2, "compute"                           :235

+```
+
+Each instruction line shows:
+- Program counter (left-aligned)
+- Opcode
+- Operands (comma-separated)
+- Source line number (`:N` suffix, right-aligned)
+
+Function creation instructions include a cross-reference annotation showing the target function's name:
+
+```
+  3     function       5, 12                                  :235  ; -> [12] helper_fn
+```
+
+## diff_ir.ce
+
+Compares mcode IR (before optimization) with streamline IR (after optimization), showing what the optimizer changed. Useful for understanding which instructions were eliminated, specialized, or rewritten.
+
+```bash
+cell diff_ir <file>                  # diff all functions
+cell diff_ir --fn <N|name> <file>    # diff only one function

+
+```
+=== [0] <anonymous> (args=1, slots=40) ===
+  17 eliminated, 51 rewritten
+
+  --- line 4: if (n <= 1) { ---
+  - 1     is_int         4, 1                          :4
+  + 1     is_int         3, 1                          :4  (specialized)
+  - 3     is_int         5, 2                          :4
+  + 3     _nop_tc_1                                         (eliminated)
+```
+
+Summary mode gives a quick overview:
+
+```
+  [0] <anonymous>:                       17 eliminated, 51 rewritten
+  [1] <anonymous>:                       65 eliminated, 181 rewritten
+  total: 86 eliminated, 250 rewritten across 4 functions
+```
+
+## xref.ce
+
+Cross-reference / call graph tool. Shows which functions create other functions (via `function` instructions), building a creation tree.
+
+```bash
+cell xref <file>                     # full creation tree
+cell xref --callers <N> <file>       # who creates function [N]?
+cell xref --callees <N> <file>       # what does [N] create/call?
+cell xref --dot <file>               # DOT graph for graphviz
+cell xref --optimized <file>         # use optimized IR
+```
+
+| Flag | Description |
+|------|-------------|
+| (none) | Indented creation tree from main |
+| `--callers <N>` | Show which functions create function [N] |
+| `--callees <N>` | Show what function [N] creates (use -1 for main) |

+demo_disasm.cm
+  [0] <anonymous>
+  [1] <anonymous>
+  [2] <anonymous>
+```
+
+Caller/callee query:
+
+```
+Callers of [0] <anonymous>:
+  demo_disasm.cm at line 3
+```
+
+DOT output can be piped to graphviz: `cell xref --dot file.cm | dot -Tpng -o xref.png`
+
+## cfg.ce
+
+Control flow graph tool. Identifies basic blocks from labels and jumps, computes edges, and detects loop back-edges.
+
+```bash
+cell cfg --fn <N|name> <file>        # text CFG for function
+cell cfg --dot --fn <N|name> <file>  # DOT output for graphviz
+cell cfg <file>                      # text CFG for all functions
+cell cfg --optimized <file>          # use optimized IR
+```
+
+| Flag | Description |
+|------|-------------|
+| `--fn <N\|name>` | Filter to specific function by index or name |
+| `--dot` | Output DOT format for graphviz |
+| `--optimized` | Use optimized IR instead of raw mcode |
+
+### Output Format

+=== [0] <anonymous> ===
+  B0 [pc 0-2, line 4]:
+    0     access         2, 1
+    1     is_int         4, 1
+    2     jump_false     4, "rel_ni_2"
+    -> B3 "rel_ni_2" (jump)
+    -> B1 (fallthrough)
+
+  B1 [pc 3-4, line 4]:
+    3     is_int         5, 2
+    4     jump_false     5, "rel_ni_2"
+    -> B3 "rel_ni_2" (jump)
+    -> B2 (fallthrough)
+```
+
+Each block shows its ID, PC range, source lines, instructions, and outgoing edges. Loop back-edges (target PC <= source PC) are annotated.
+
+## slots.ce
+
+Slot data flow analysis. Builds use-def chains for every slot in a function, showing where each slot is defined and used. Optionally captures type information from streamline.
+
+```bash
+cell slots --fn <N|name> <file>              # slot summary for function
+cell slots --slot <N> --fn <N|name> <file>   # trace slot N
+cell slots <file>                            # slot summary for all functions
+```
+
+| Flag | Description |
+|------|-------------|
+| `--fn <N\|name>` | Filter to specific function by index or name |
+| `--slot <N>` | Show chronological DEF/USE trace for a specific slot |
+
+### Output Format
+
+Summary shows each slot with its def count, use count, inferred type, and first definition. Dead slots (defined but never used) are flagged:
+
+```
+=== [0] <anonymous> (args=1, slots=40) ===
+  slot    defs    uses    type        first-def
+  s0      0       0       -           (this)
+  s1      0       10      -           (arg 0)
+  s2      1       6       -           pc 0: access
+  s10     1       0       -           pc 29: invoke  <- dead
+```
+
+Slot trace (`--slot N`) shows every DEF and USE in program order:
+
+```
+=== slot 3 in [0] <anonymous> ===
+  DEF  pc 5:     le_int         3, 1, 2                       :4
+  DEF  pc 11:    le_float       3, 1, 2                       :4
+  DEF  pc 17:    le_text        3, 1, 2                       :4
+  USE  pc 31:    jump_false     3, "if_else_0"                :4
+```
+
+## seed.ce
+
+Regenerates the boot seed files in `boot/`. These are pre-compiled mcode IR (JSON) files that bootstrap the compilation pipeline on cold start.
+
+```bash
+cell seed                # regenerate all boot seeds
+cell seed --clean        # also clear the build cache after
+```
+
+The script compiles each pipeline module (tokenize, parse, fold, mcode, streamline) and `internal/bootstrap.cm` through the current pipeline, encodes the output as JSON, and writes it to `boot/<name>.cm.mcode`.
+
+**When to regenerate seeds:**
+- Before a release or distribution
+- When the pipeline source changes in a way the existing seeds can't compile the new source (e.g. language-level changes)
+- Seeds do NOT need regenerating for normal development — the engine recompiles pipeline modules from source automatically via the content-addressed cache
+
+## ir_report.ce
+
+The optimizer flight recorder. Runs the full pipeline with structured logging and outputs machine-readable, diff-friendly JSON. This is the most detailed tool for understanding what the optimizer did and why.
+
+```bash
+cell ir_report [options] <file.ce|file.cm>
+```
+
+### Options
+
+| Flag | Description |
+|------|-------------|
+| `--summary` | Per-pass JSON summaries with instruction counts and timing (default) |
+| `--events` | Include rewrite events showing each optimization applied |
+| `--types` | Include type delta records showing inferred slot types |
+| `--ir-before=PASS` | Print canonical IR before a specific pass |
+| `--ir-after=PASS` | Print canonical IR after a specific pass |
+| `--ir-all` | Print canonical IR before and after all passes |
+| `--full` | Everything: summary + events + types + ir-all |
+
+With no flags, `--summary` is the default.
+
+### Output Format
+
+Output is line-delimited JSON. Each line is a self-contained JSON object with a `type` field:
+
+**`type: "pass"`** — Per-pass summary with categorized instruction counts before and after:
+
+```json
+{
+  "type": "pass",
+  "pass": "eliminate_type_checks",
+  "fn": "fib",
+  "ms": 0.12,
+  "changed": true,
+  "before": {"instr": 77, "nop": 0, "guard": 16, "branch": 28, ...},
+  "after":  {"instr": 77, "nop": 1, "guard": 15, "branch": 28, ...},
+  "changes": {"guards_removed": 1, "nops_added": 1}
+}
+```
+
+**`type: "event"`** — Individual rewrite event with before/after instructions and reasoning:
+
+```json
+{
+  "type": "event",
+  "pass": "eliminate_type_checks",
+  "rule": "incompatible_type_forces_jump",
+  "at": 3,
+  "before": [["is_int", 5, 2, 4, 9], ["jump_false", 5, "rel_ni_2", 4, 9]],
+  "after": ["_nop_tc_1", ["jump", "rel_ni_2", 4, 9]],
+  "why": {"slot": 2, "known_type": "float", "checked_type": "int"}
+}
+```
+
+**`type: "types"`** — Inferred type information for a function:
+
+```json
+{
+  "type": "types",
+  "fn": "fib",
+  "param_types": {},
+  "slot_types": {"25": "null"}
+}
+```
+
+**`type: "ir"`** — Canonical IR text for a function at a specific point:
+
+```json
+{
+  "type": "ir",
+  "when": "before",
+  "pass": "all",
+  "fn": "fib",
+  "text": "fn fib (args=1, slots=26)\n  @0    access          s2, 2\n  ..."
+}
+```
+
+### Rewrite Rules
+
+Each pass records events with named rules:
+
+**eliminate_type_checks:**
+- `known_type_eliminates_guard` — type already known, guard removed
+- `incompatible_type_forces_jump` — type conflicts, conditional jump becomes unconditional
+- `num_subsumes_int_float` — num check satisfied by int or float
+- `dynamic_to_field` — load_dynamic/store_dynamic narrowed to field access
+- `dynamic_to_index` — load_dynamic/store_dynamic narrowed to index access
+
+**simplify_algebra:**
+- `add_zero`, `sub_zero`, `mul_one`, `div_one` — identity operations become moves
+- `mul_zero` — multiplication by zero becomes constant
+- `self_eq`, `self_ne` — same-slot comparisons become constants
+
+**simplify_booleans:**
+- `not_jump_false_fusion` — not + jump_false fused into jump_true
+- `not_jump_true_fusion` — not + jump_true fused into jump_false
+- `double_not` — not + not collapsed to move
+
+**eliminate_moves:**
+- `self_move` — move to same slot becomes nop
+
+**eliminate_dead_jumps:**
+- `jump_to_next` — jump to immediately following label becomes nop
+
+### Canonical IR Format
+
+The `--ir-all`, `--ir-before`, and `--ir-after` flags produce a deterministic text representation of the IR:
+
+```
+fn fib (args=1, slots=26)
+  @0    access          s2, 2
+  @1    is_int          s4, s1                          ; [guard]
+  @2    jump_false      s4, "rel_ni_2"                  ; [branch]
+  @3    --- nop (tc) ---
+  @4    jump            "rel_ni_2"                      ; [branch]
+  @5    lt_int          s3, s1, s2
+  @6    jump            "rel_done_4"                    ; [branch]
+      rel_ni_2:
+  @8    is_num          s4, s1                          ; [guard]
+```
+
+Properties:
+- `@N` is the raw array index, stable across passes (passes replace, never insert or delete)
+- `sN` prefix distinguishes slot operands from literal values
+- String operands are quoted
+- Labels appear as indented headers with a colon
+- Category tags in brackets: `[guard]`, `[branch]`, `[load]`, `[store]`, `[call]`, `[arith]`, `[move]`, `[const]`
+- Nops shown as `--- nop (reason) ---` with reason codes: `tc` (type check), `bl` (boolean), `mv` (move), `dj` (dead jump), `ur` (unreachable)
+
+### Examples
+
+```bash
+# what passes changed something?
+cell ir_report --summary myfile.ce | jq 'select(.changed)'
+
+# list all rewrite rules that fired
+cell ir_report --events myfile.ce | jq 'select(.type == "event") | .rule'
+
+# diff IR before and after optimization
+cell ir_report --ir-all myfile.ce | jq -r 'select(.type == "ir") | .text'
+
+# full report for analysis
+cell ir_report --full myfile.ce > report.json
+```
+
+## ir_stats.cm
+
+A utility module used by `ir_report.ce` and available for custom tooling. Not a standalone tool.
+
+```javascript
+var ir_stats = use("ir_stats")
+
+ir_stats.detailed_stats(func)                    // categorized instruction counts
+ir_stats.ir_fingerprint(func)                    // djb2 hash of instruction array
+ir_stats.canonical_ir(func, name, opts)          // deterministic text representation
+ir_stats.type_snapshot(slot_types)               // frozen copy of type map
+ir_stats.type_delta(before_types, after_types)   // compute type changes
+ir_stats.category_tag(op)                        // classify an opcode
+```
+
+### Instruction Categories
+
+`detailed_stats` classifies each instruction into one of these categories:
+
+| Category | Opcodes |
+|----------|---------|
+| load     | `load_field`, `load_index`, `load_dynamic`, `get`, `access` (non-constant) |
+| store    | `store_field`, `store_index`, `store_dynamic`, `set_var`, `put`, `push` |
+| branch   | `jump`, `jump_true`, `jump_false`, `jump_not_null` |
+| call     | `invoke`, `goinvoke` |
+| guard    | `is_int`, `is_text`, `is_num`, `is_bool`, `is_null`, `is_array`, `is_func`, `is_record`, `is_stone` |
+| arith    | `add_int`, `sub_int`, ..., `add_float`, ..., `concat`, `neg_int`, `neg_float`, bitwise ops |
+| move     | `move` |
+| const    | `int`, `true`, `false`, `null`, `access` (with constant value) |
+| label    | string entries that are not nops |
+| nop      | strings starting with `_nop_` |
+| other    | everything else (`frame`, `setarg`, `array`, `record`, `function`, `return`, etc.) |

-
-- **Modules** (`.cm`) — return a value, cached and frozen
-- **Actors** (`.ce`) — run independently, communicate via messages
-- **C files** (`.c`) — compiled to native libraries
-
-Actors never share memory. They communicate by sending messages, which are automatically serialized. This makes concurrent programming safe and predictable.

+title: "Kim Encoding"
+description: "Compact character and count encoding"
+weight: 80
+type: "docs"
+---
+
+Kim is a character and count encoding designed by Douglas Crockford. It encodes Unicode characters and variable-length integers using continuation bytes. Kim is simpler and more compact than UTF-8 for most text.
+
+## Continuation Bytes
+
+The fundamental idea in Kim is the continuation byte:
+
+```
+C  D  D  D  D  D  D  D
+```
+
+- **C** — continue bit. If 1, read another byte. If 0, this is the last byte.
+- **D** (7 bits) — data bits.
+
+To decode: shift the accumulator left by 7 bits, add the 7 data bits. If the continue bit is 1, repeat with the next byte. If 0, the value is complete.
+
+To encode: take the value, emit 7 bits at a time from most significant to least significant, setting the continue bit on all bytes except the last.
+
+## Character Encoding
+
+Kim encodes Unicode codepoints directly as continuation byte sequences:
+
+| Range | Bytes | Characters |
+|-------|-------|------------|
+| U+0000 to U+007F | 1 | ASCII |
+| U+0080 to U+3FFF | 2 | First quarter of BMP |
+| U+4000 to U+10FFFF | 3 | All other Unicode |
+
+Unlike UTF-8, there is no need for surrogate pairs or escapement. Every Unicode character, including emoji and characters from extended planes, is encoded in at most 3 bytes.
+
+### Examples
+
+```
+'A'       (U+0041)  →  41
+'é'       (U+00E9)  →  81 69
+'💩'      (U+1F4A9)  →  87 E9 29
+```
+
+## Count Encoding
+
+Kim is also used for encoding counts (lengths, sizes). The same continuation byte format represents non-negative integers of arbitrary size:
+
+| Range | Bytes |
+|-------|-------|
+| 0 to 127 | 1 |
+| 128 to 16383 | 2 |
+| 16384 to 2097151 | 3 |
+
+## Comparison with UTF-8
+
+| Property | Kim | UTF-8 |
+|----------|-----|-------|
+| ASCII | 1 byte | 1 byte |
+| BMP (first quarter) | 2 bytes | 2-3 bytes |
+| Full Unicode | 3 bytes | 3-4 bytes |
+| Self-synchronizing | No | Yes |
+| Sortable | No | Yes |
+| Simpler to implement | Yes | No |
+| Byte count for counts | Variable (7 bits/byte) | Not applicable |
+
+Kim trades self-synchronization (the ability to find character boundaries from any position) for simplicity and compactness. In practice, Kim text is accessed sequentially, so self-synchronization is not needed.
+
+## Usage in ƿit
+
+Kim is used internally by blobs and by the Nota message format.
+
+### In Blobs
+
+The `blob.write_text` and `blob.read_text` functions use Kim to encode text into binary data:
+
+```javascript
+var blob = use('blob')
+var b = blob.make()
+blob.write_text(b, "hello")  // Kim-encoded length + characters
+stone(b)
+var text = blob.read_text(b, 0)  // "hello"
+```
+
+### In Nota
+
+Nota uses Kim for two purposes:
+
+1. **Counts** — array lengths, text lengths, blob sizes, record pair counts
+2. **Characters** — text content within Nota messages
+
+The preamble byte of each Nota value incorporates the first few bits of a Kim-encoded count, with the continue bit indicating whether more bytes follow.
+
+See [Nota Format](#nota) for the full specification.

+title: "ƿit Language"
+description: "Syntax, types, operators, and built-in functions"
+weight: 10
+type: "docs"
+---
+
+ƿit is a scripting language for actor-based programming. It combines a familiar syntax with a prototype-based object system and strict immutability semantics.
+
+## Basics
+
+### Variables and Constants
+
+Variables are declared with `var`, constants with `def`. All declarations must be initialized and must appear at the function body level — not inside `if`, `while`, `for`, or `do` blocks.
+
+```javascript
+var x = 10
+var name = "pit"
+var empty = null
+
+def PI = 3.14159   // constant, cannot be reassigned
+
+var a = 1, b = 2, c = 3  // multiple declarations
+```
+
+### Data Types
+
+ƿit has eight fundamental types:
+
+- **number** — DEC64 decimal floating point (no rounding errors)
+- **text** — Unicode strings
+- **logical** — `true` or `false`
+- **null** — the absence of a value (no `undefined`)
+- **array** — ordered, numerically-indexed sequences
+- **object** — key-value records with prototype inheritance
+- **blob** — binary data (bits, not bytes)
+- **function** — first-class callable values
+
+### Literals
+
+```javascript
+// Numbers
+42
+3.14
+-5
+0
+1e3           // scientific notation (1000)
+
+// Text
+"hello"
+`template ${x}`   // string interpolation
+`${1 + 2}`        // expression interpolation
+
+// Logical
+true
+false
+
+// Null
+null
+
+// Arrays
+[1, 2, 3]
+[]
+
+// Objects
+{a: 1, b: "two"}
+{}
+
+// Regex
+/\d+/
+/hello/i          // with flags
+```
+
+## Operators
+
+### Arithmetic
+
+```javascript
+2 + 3      // 5
+5 - 3      // 2
+3 * 4      // 12
+12 / 4     // 3
+10 % 3     // 1
+2 ** 3     // 8 (exponentiation)
+```
+
+### Comparison
+
+All comparisons are strict — there is no type coercion.
+
+```javascript
+5 == 5     // true
+5 != 6     // true
+3 < 5      // true
+5 > 3      // true
+3 <= 3     // true
+5 >= 5     // true
+```
+
+### Logical
+
+```javascript
+true && true     // true
+true && false    // false
+false || true    // true
+false || false   // false
+!true            // false
+!false           // true
+```
+
+Logical operators short-circuit:
+
+```javascript
+var called = false
+var fn = function() { called = true; return true }
+var r = false && fn()   // fn() not called
+r = true || fn()        // fn() not called
+```
+
+### Bitwise
+
+```javascript
+5 & 3       // 1   (AND)
+5 | 3       // 7   (OR)
+5 ^ 3       // 6   (XOR)
+~0          // -1  (NOT)
+1 << 3      // 8   (left shift)
+8 >> 3      // 1   (right shift)
+-1 >>> 1    // 2147483647 (unsigned right shift)
+```
+
+### Unary
+
+```javascript
++5          // 5
+-5          // -5
+-(-5)       // 5
+```
+
+### Increment and Decrement
+
+```javascript
+var x = 5
+x++         // returns 5, x becomes 6 (postfix)
+++x         // returns 7, x becomes 7 (prefix)
+x--         // returns 7, x becomes 6 (postfix)
+--x         // returns 5, x becomes 5 (prefix)
+```
+
+### Compound Assignment
+
+```javascript
+var x = 10
+x += 3      // 13
+x -= 3      // 10
+x *= 2      // 20
+x /= 4     // 5
+x %= 3      // 2
+```
+
+### Ternary
+
+```javascript
+var a = true ? 1 : 2       // 1
+var b = false ? 1 : 2      // 2
+var c = true ? (false ? 1 : 2) : 3  // 2 (nested)
+```
+
+### Comma
+
+The comma operator evaluates all expressions and returns the last.
+
+```javascript
+var x = (1, 2, 3)  // 3
+```
+
+### In
+
+Test whether a key exists in an object.
+
+```javascript
+var o = {a: 1}
+"a" in o    // true
+"b" in o    // false
+```
+
+### Delete
+
+Remove a key from an object.
+
+```javascript
+var o = {a: 1, b: 2}
+delete o.a
+"a" in o    // false
+o.b         // 2
+```
+
+## Property Access
+
+### Dot and Bracket
+
+```javascript
+var o = {x: 10}
+o.x           // 10 (dot read)
+o.x = 20      // dot write
+o["x"]        // 20 (bracket read)
+var key = "x"
+o[key]        // 20 (computed bracket)
+o["y"] = 30   // bracket write
+```
+
+### Object as Key
+
+Objects can be used as keys in other objects.
+
+```javascript
+var k = {}
+var o = {}
+o[k] = 42
+o[k]          // 42
+o[{}]         // null (different object)
+k in o        // true
+delete o[k]
+k in o        // false
+```
+
+### Chained Access
+
+```javascript
+var d = {a: {b: [1, {c: 99}]}}
+d.a.b[1].c    // 99
+```
+
+## Arrays
+
+Arrays are **distinct from objects**. They are ordered, numerically-indexed sequences.
+
+```javascript
+var arr = [1, 2, 3]
+arr[0]              // 1
+arr[2] = 10         // [1, 2, 10]
+length(arr)         // 3
+```
+
+### Push and Pop
+
+```javascript
+var a = [1, 2]
+a[] = 3             // push: [1, 2, 3]
+length(a)           // 3
+var v = a[]         // pop: v is 3, a is [1, 2]
+length(a)           // 2
+```
+
+## Objects
+
+Objects are key-value records with prototype-based inheritance.
+
+```javascript
+var point = {x: 10, y: 20}
+point.x             // 10
+point["y"]          // 20
+```
+
+### Prototypes
+
+```javascript
+// Create object with prototype
+var parent = {x: 10}
+var child = meme(parent)
+child.x             // 10 (inherited)
+proto(child)        // parent
+
+// Override does not mutate parent
+child.x = 20
+parent.x            // 10
+```
+
+### Mixins
+
+```javascript
+var p = {a: 1}
+var m1 = {b: 2}
+var m2 = {c: 3}
+var child = meme(p, [m1, m2])
+child.a             // 1 (from prototype)
+child.b             // 2 (from mixin)
+child.c             // 3 (from mixin)
+```
+
+## Control Flow
+
+### If / Else
+
+```javascript
+var x = 0
+if (true) x = 1
+if (false) x = 2 else x = 3
+if (false) x = 4
+else if (true) x = 5
+else x = 6
+```
+
+### While
+
+```javascript
+var i = 0
+while (i < 5) i++
+
+// break
+i = 0
+while (true) {
+  if (i >= 3) break
+  i++
+}
+
+// continue
+var sum = 0
+i = 0
+while (i < 5) {
+  i++
+  if (i % 2 == 0) continue
+  sum += i
+}
+```
+
+### For
+
+Variables cannot be declared in the for initializer. Declare them at the function body level.
+
+```javascript
+var sum = 0
+var i = 0
+for (i = 0; i < 5; i++) sum += i
+
+// break
+sum = 0
+i = 0
+for (i = 0; i < 10; i++) {
+  if (i == 5) break
+  sum += i
+}
+
+// continue
+sum = 0
+i = 0
+for (i = 0; i < 5; i++) {
+  if (i % 2 == 0) continue
+  sum += i
+}
+
+// nested
+sum = 0
+var j = 0
+for (i = 0; i < 3; i++) {
+  for (j = 0; j < 3; j++) {
+    sum++
+  }
+}
+```
+
+## Functions
+
+### Function Expressions
+
+```javascript
+var add = function(a, b) { return a + b }
+add(2, 3)           // 5
+```
+
+### Arrow Functions
+
+```javascript
+var double = x => x * 2
+double(5)           // 10
+
+var sum = (a, b) => a + b
+sum(2, 3)           // 5
+
+var block = x => {
+  var y = x * 2
+  return y + 1
+}
+block(5)            // 11
+```
+
+### Return
+
+A function with no `return` returns `null`. An early `return` exits immediately.
+
+```javascript
+var fn = function() { var x = 1 }
+fn()                // null
+
+var fn2 = function() { return 1; return 2 }
+fn2()               // 1
+```
+
+### Arguments
+
+Functions can have at most **4 parameters**. Use a record to pass more values.
+
+Extra arguments are ignored. Missing arguments are `null`.
+
+```javascript
+var fn = function(a, b) { return a + b }
+fn(1, 2, 3)        // 3 (extra arg ignored)
+
+var fn2 = function(a, b) { return a }
+fn2(1)              // 1 (b is null)
+
+// More than 4 parameters — use a record
+var draw = function(shape, opts) {
+  // opts.x, opts.y, opts.color, ...
+}
+```
+
+### Immediately Invoked Function Expression
+
+```javascript
+var r = (function(x) { return x * 2 })(21)  // 42
+```
+
+### Closures
+
+Functions capture variables from their enclosing scope.
+
+```javascript
+var make = function(x) {
+  return function(y) { return x + y }
+}
+var add5 = make(5)
+add5(3)             // 8
+```
+
+Captured variables can be mutated:
+
+```javascript
+var counter = function() {
+  var n = 0
+  return function() { n = n + 1; return n }
+}
+var c = counter()
+c()                 // 1
+c()                 // 2
+```
+
+### Recursion
+
+```javascript
+var fact = function(n) {
+  if (n <= 1) return 1
+  return n * fact(n - 1)
+}
+fact(5)             // 120
+```
+
+### This Binding
+
+When a function is called as a method, `this` refers to the object.
+
+```javascript
+var obj = {
+  val: 10,
+  get: function() { return this.val }
+}
+obj.get()           // 10
+```
+
+### Currying
+
+```javascript
+var f = function(a) {
+  return function(b) {
+    return function(c) { return a + b + c }
+  }
+}
+f(1)(2)(3)          // 6
+```
+
+## Identifiers
+
+Identifiers can contain `?` and `!` characters, both as suffixes and mid-name.
+
+```javascript
+var nil? = (x) => x == null
+nil?(null)          // true
+nil?(42)            // false
+
+var set! = (x) => x + 1
+set!(5)             // 6
+
+var is?valid = (x) => x > 0
+is?valid(3)         // true
+
+var do!stuff = () => 42
+do!stuff()          // 42
+```
+
+The `?` in an identifier is not confused with the ternary operator:
+
+```javascript
+var nil? = (x) => x == null
+var a = nil?(null) ? "yes" : "no"   // "yes"
+```
+
+## Type Checking
+
+### Type Functions
+
+```javascript
+is_number(42)           // true
+is_text("hi")           // true
+is_logical(true)        // true
+is_object({})           // true (records only)
+is_array([])            // true
+is_function(function(){})  // true
+is_null(null)           // true
+is_object([])           // false (arrays are not records)
+is_object("hello")      // false (text is not a record)
+is_array({})            // false (records are not arrays)
+```
+
+### Truthiness
+
+Falsy values: `false`, `0`, `""`, `null`. Everything else is truthy.
+
+```javascript
+if (0) ...              // not entered
+if ("") ...             // not entered
+if (null) ...           // not entered
+if (1) ...              // entered
+if ("hi") ...           // entered
+if ({}) ...             // entered
+if ([]) ...             // entered
+```
+
+## Immutability with Stone
+
+The `stone()` function makes values permanently immutable.
+
+```javascript
+var o = {x: 1}
+is_stone(o)             // false
+stone(o)
+is_stone(o)             // true
+o.x = 2                 // disrupts!
+```
+
+Stone is **deep** — all nested objects and arrays are also frozen. This cannot be reversed.
+
+## Function Proxy
+
+A function with two parameters (`name`, `args`) acts as a proxy when properties are accessed on it. Any method call on the function dispatches through the proxy.
+
+```javascript
+var proxy = function(name, args) {
+  return `${name}:${length(args)}`
+}
+proxy.hello()           // "hello:0"
+proxy.add(1, 2)         // "add:2"
+proxy["method"]()       // "method:0"
+var m = "dynamic"
+proxy[m]()              // "dynamic:0"
+```
+
+For non-proxy functions, property access disrupts:
+
+```javascript
+var fn = function() { return 1 }
+fn.foo                  // disrupts
+fn.foo = 1              // disrupts
+```
+
+## Regex
+
+Regex literals are written with forward slashes, with optional flags.
+
+```javascript
+var r = /\d+/
+var result = extract("abc123", r)
+result[0]               // "123"
+
+var ri = /hello/i
+var result2 = extract("Hello", ri)
+result2[0]              // "Hello"
+```
+
+## Error Handling
+
+ƿit uses `disrupt` and `disruption` for error handling. A `disrupt` signals that something went wrong. The `disruption` block attached to a function catches it.
+
+```javascript
+var safe_divide = function(a, b) {
+  if (b == 0) disrupt
+  return a / b
+} disruption {
+  log.error("something went wrong")
+}
+```
+
+`disrupt` is a bare keyword — it does not carry a value. The `disruption` block knows that something went wrong, but not what.
+
+### Re-raising
+
+A `disruption` block can re-raise by calling `disrupt` again:
+
+```javascript
+var outer = function() {
+  var inner = function() { disrupt } disruption { disrupt }
+  inner()
+} disruption {
+  // caught here after re-raise
+}
+outer()
+```
+
+### Testing for Disruption
+
+```javascript
+var should_disrupt = function(fn) {
+  var caught = false
+  var wrapper = function() {
+    fn()
+  } disruption {
+    caught = true
+  }
+  wrapper()
+  return caught
+}
+```
+
+If an actor has an unhandled disruption, it crashes.
+
+## Self-Referencing Structures
+
+Objects can reference themselves:
+
+```javascript
+var o = {name: "root"}
+o.self = o
+o.self.self.name        // "root"
+```
+
+## Variable Shadowing
+
+Inner functions can shadow outer variables:
+
+```javascript
+var x = 10
+var fn = function() {
+  var x = 20
+  return x
+}
+fn()                    // 20
+x                       // 10
+```

+title: "Logging"
+description: "Configurable channel-based logging with sinks"
+weight: 25
+type: "docs"
+---
+
+Logging in ƿit is channel-based. Any `log.X(value)` call writes to channel `"X"`. Channels are routed to **sinks** — named destinations that format and deliver log output to the console or to files.
+
+## Channels
+
+Three channels are conventional:
+
+| Channel | Usage |
+|---------|-------|
+| `log.console(msg)` | General output |
+| `log.error(msg)` | Errors and warnings |
+| `log.system(msg)` | Internal system messages |
+
+Any name works. `log.debug(msg)` creates channel `"debug"`, `log.perf(msg)` creates `"perf"`, and so on.
+
+```javascript
+log.console("server started on port 8080")
+log.error("connection refused")
+log.debug({query: "SELECT *", rows: 42})
+```
+
+Non-text values are JSON-encoded automatically.
+
+## Default Behavior
+
+With no configuration, a default sink routes `console`, `error`, and `system` to the terminal in pretty format. The `error` channel includes a stack trace by default:
+
+```
+[a3f12] [console] server started on port 8080
+[a3f12] [error] connection refused
+    at handle_request (server.ce:42:3)
+    at main (main.ce:5:1)
+```
+
+The format is `[actor_id] [channel] message`. Error stack traces are always on unless you explicitly configure a sink without them.
+
+## Configuration
+
+Logging is configured in `.cell/log.toml`. Each `[sink.NAME]` section defines a sink.
+
+```toml
+[sink.terminal]
+type = "console"
+format = "bare"
+channels = ["console"]
+
+[sink.errors]
+type = "file"
+path = ".cell/logs/errors.jsonl"
+channels = ["error"]
+
+[sink.everything]
+type = "file"
+path = ".cell/logs/all.jsonl"
+channels = ["*"]
+exclude = ["console"]
+```
+
+### Sink fields
+
+| Field | Values | Description |
+|-------|--------|-------------|
+| `type` | `"console"`, `"file"` | Where output goes |
+| `format` | `"pretty"`, `"bare"`, `"json"` | How output is formatted |
+| `channels` | array of names, or `["*"]` | Which channels this sink receives. Quote `'*'` on the CLI to prevent shell glob expansion. |
+| `exclude` | array of names | Channels to skip (useful with `"*"`) |
+| `stack` | array of channel names | Channels that capture a stack trace |
+| `path` | file path | Output file (file sinks only) |
+
+### Formats
+
+**pretty** — human-readable, one line per message. Includes actor ID, channel, source location, and message.
+
+```
+[a3f12] [console] main.ce:5 server started
+```
+
+**bare** — minimal. Actor ID and message only.
+
+```
+[a3f12] server started
+```
+
+**json** — structured JSONL (one JSON object per line). Used for file sinks and machine consumption.
+
+```json
+{"actor_id":"a3f12...","timestamp":1702656000.5,"channel":"console","event":"server started","source":{"file":"main.ce","line":5,"col":3,"fn":"init"}}
+```
+
+## Log Records
+
+Every log call produces a record:
+
+```javascript
+{
+  actor_id: "a3f12...",       // full actor GUID
+  timestamp: 1702656000.5,    // seconds since epoch
+  channel: "console",         // channel name
+  event: "the message",       // value passed to log
+  source: {
+    file: "main.ce",
+    line: 5,
+    col: 3,
+    fn: "init"
+  }
+}
+```
+
+File sinks write one JSON-encoded record per line. Console sinks format the record according to their format setting.
+
+## Stack Traces
+
+The `error` channel captures stack traces by default. To enable stack traces for other channels, add a `stack` field to a sink — an array of channel names that should include a call stack.
+
+Via the CLI:
+
+```bash
+pit log add terminal console --channels=console,error,debug --stack=error,debug
+```
+
+Or in `log.toml`:
+
+```toml
+[sink.terminal]
+type = "console"
+format = "bare"
+channels = ["console", "error", "debug"]
+stack = ["error", "debug"]
+```
+
+Only channels listed in `stack` get stack traces. Other channels on the same sink print without one:
+
+```
+[a3f12] server started
+[a3f12] connection failed
+    at handle_request (server.ce:42:3)
+    at process (router.ce:18:5)
+    at main (main.ce:5:1)
+```
+
+With JSON format, a `stack` array is added to the record for channels that have stack capture enabled:
+
+```json
+{"actor_id":"a3f12...","channel":"error","event":"connection failed","source":{"file":"server.ce","line":42,"col":3,"fn":"handle_request"},"stack":[{"fn":"handle_request","file":"server.ce","line":42,"col":3},{"fn":"process","file":"router.ce","line":18,"col":5},{"fn":"main","file":"main.ce","line":5,"col":1}]}
+```
+
+Channels without `stack` configuration produce no stack field. Capturing stacks adds overhead — enable it for debugging, not production.
+
+## CLI
+
+The `pit log` command manages sinks and reads log files. See [CLI — pit log](/docs/cli/#pit-log) for the full reference.
+
+```bash
+pit log list                                           # show sinks
+pit log add terminal console --format=bare --channels=console
+pit log add dump file .cell/logs/dump.jsonl '--channels=*' --exclude=console
+pit log add debug console --channels=error,debug --stack=error,debug
+pit log remove terminal
+pit log read dump --lines=20 --channel=error
+pit log tail dump
+```
+
+## Examples
+
+### Development setup
+
+Route console output to the terminal with minimal formatting. Send everything else to a structured log file for debugging.
+
+```toml
+[sink.terminal]
+type = "console"
+format = "bare"
+channels = ["console"]
+
+[sink.debug]
+type = "file"
+path = ".cell/logs/debug.jsonl"
+channels = ["*"]
+exclude = ["console"]
+```
+
+```javascript
+log.console("listening on :8080")   // -> terminal: [a3f12] listening on :8080
+log.error("bad request")            // -> debug.jsonl only
+log.debug({latency: 0.042})         // -> debug.jsonl only
+```
+
+### Separate error log
+
+Keep a dedicated error log alongside a full dump.
+
+```toml

-# Cell actor scripting language
-
-Cell is a Misty [https://mistysystem.com](https://mistysystem.com) implementation.
-
-## Memory
-Values are 32 bit for 32 bit builds and 64 bit for 64 bit builds.
-
-### 32 bit value
-
-LSB = 0
-payload is a 31 bit signed int
-
-LSB = 01
-payload is a 30 bit pointer
-
-LSB = 11
-next 3 bits = special tag. 27 bits of payload.
-
-### 64 bit value
-LSB = 0
-payload is a 32 bit signed int, using high 32 bits
-
-LSB = 01
-payload is a 61 bit pointer
-
-LSB = 101
-Short float: a 61 bit double, with 3 less exponent bits
-
-LSB = 11
-Special tag: next 3 bits. 5 bits total. 59 bits of payload. 8 total special tags.
-
-Special tags:
-1: Bool. Payload is 0 or 1.
-2: null. payload is 0.
-3: exception.
-4: string.
-  Immediate string. Next 3 low bits = length in bytes. Rest is string data. This allows for strings up to 7 ascii letters. Encoded in utf8.
-
-## Numbers and math
-Cell can be compiled with different levels of exactness for numeracy. Any number which cannot be represented exactly becomes "null". Any numeric operation which includes "null" results in "null".
-
-Using short floats in a 64 bit system means you have doubles in the range of +- 10^38, not the full range of double. If you create a number out of that range, it's null.
-
-You can also compile a 64 bit system with full precision doubles, but this will use more memory and may be slower.
-
-You can also compile a 64 bit system with 32 bit floats, stored as a 32 bit int is. Again, out of the 32 bit float range = null.
-
-You can compile without floating point support at all; 32 bit ints are then used for fixed point calculations.
-
-Or, you can compile using Dec64, which is a 64 bit decimal floating point format, for exact precision.
-
-## Objects
-Objects are heap allocated, referenced by a pointer value. They are all preceded by an object header, the length of a word on the system.
-  
-### 64 bit build
-56 bits capacity
-1 bit memory reclamation flag: note that this obj has already been moved
-2 bit reserved (per object)
-1 bit stone: note that this obj is immutable
-3 bit type: note the type of the object
-1 bit: fwd: note that this obj is a forward linkage
-
-Last bit ..1:
-The forward type indicates that the object (an array, blob, pretext, or record) has grown beyond its capacity and is now residing at a new address. The remaining 63 bits contain the address of the enlarged object. Forward linkages are cleaned up by the memory reclaimer.
-
-Type 7: C light C object
-
-Header
-Pointer
-
-Capacity is an ID of a registered C type.
-Pointer is a pointer to the opaque C object.
-
-Type 0: Array
-Header
-Length
-Element[]
-
-Capacity is number of elements the array can hold. Length is number of elements in use. Number of words used by an array is capacity + 2.
-
-Type 1: blob
-Header
-Length
-Bit[]
-Capacity is number of bits the blob can hold. Length is number of bits in use. Bits follow, from [0] to [capacity - 1], with [0] bit in the most significant position of word 2, and [63] in the least significant position of word 2. The last word is zero filled, if necessary.
-
-Number of words used is (capacity + 63) // 64 + 2
-
-Type 2: Text
-Text has two forms, depending on if it is stone or not, which changes the meaning of its length word.
-
-Header
-Length(pretext) or Hash(text)
-Character[0] and character[1]
-
-Capacity of pretex is the number of characters it can hold. During stoning and reclamation, capacity is set to the length.
-
-The capacity of a text is its length.
-
-The length of a pretext is the number of characters it contains; it is not greater than the capacity.
-
-Hash of a text is used for organizing records. If the hash is zero, it's not been computed yet. All texts in the immutable memory have hashes.
-
-A text object contains UTF32 characters, packed two per word. If the number of characters is odd, the least significant half of the last word is zero filled.
-
-The number of words used by a text is (capacity + 1) // 2 + 2
-
-Type 3: Record
-
-A record is an array of fields represented as key/value pairs. Fields are located by hashes of texts, using open addressing with linear probing and lazy deletion. The load factor is less than 0.5.
-
-Header
-Prototype
-Length
-Key[0]
-Value[0]
-Key[1]
-Value[1]
-...
-
-The capacity is the number of fields the record can hold. It is a power of two minus one. It is at least twice the length.
-
-The length is the number of fields that the record currently contains.
-
-A field candidate number is identified by and(key.hash, capacity). In case of hash collision, advance to the next field. If this goes past the end, continue with field 1. Field 0 is reserved.
-
-The "exception" special tag is used to mark deleted entries in the object map.
-
-The number of words used by a record is (capacity + 1) * 2.
-
-Prototypes are searched for for properties if one cannot be found on the record itself. Prototypes can have prototypes.
-
-#### key[0] and value[0]
-These are reserved for internal use, and skipped over during key probing.
-
-The first 32 bits of key are used as a 32 bit integer key, if this object has ever been used as a key itself.
-
-The last 32 bits are used as an opaque C class key. C types can be registered with the system, and each are assigned a monotonically increasing number. In the case that this object has a C type, then the bottom 32 bits of key[0] are not 0. If that is the case, then a pointer to its C object is stored in value[0].
-
-#### Valid keys & Hashing
-Keys are stored directly in object maps. There are three possibilities for a vaild key: an object text, an object record, or an immediate text.
-
-In the case of an immediate text, the hash is computed on the fly using the fash64_hash_one function, before being used to look up the key in the object map. Direct value comparison is used to confirm the key.
-
-For object texts (texts longer than 7 ascii chars), the hash is stored in the text object itself. When an object text is used as a key, a stone version is created and interned. Any program static texts reference this stoned, interned text. When looking up a heap text as a key, it is first discovered if it's in the interned table. If it's not, the key is not in the object (since all keys are interned). If it is, the interned version is returned to check against the object map. The hash of the interned text is used to look up the key in the object map, and then direct pointer comparison is used to confirm the key.
-
-For record keys, these are unique; once a record is used as a key, it gets assigned a monotonically increasing 32 bit integer, stored in key[0]. When checking it in an object map, the integer is used directly as the key. If key[0] is 0, the record has not been used as a key yet. If it's not 0, fash64_hash_one is used to compute a hash of its ID, and then direct value pointer comparison is used to confirm.
-
-### Text interning
-Texts that cannot fit in an immediate, and which are used as an object key, create a stoned and interned version (the pointer which is used as the key). Any text literals are also stoned and interned.
-
-The interning table is an open addressed hash, with a load of 0.8, using a robin hood value. Probing is done using the text hash, confirmation is done using length, and then memcmp of the text.
-
-When the GC run, a new interned text table is created. Each text literal, and each text used as a key, is added to the new table, as the live objects are copied. This keeps the interning table from becoming a graveyard. Interned values are never deleted until a GC.
-
-Type 4: Function
-
-Header
-Code
-Outer
-A function object has zero capacity and is always stone.
-
-Code is a pointer to the code object that the function executes.
-
-Outer is a pointer to the frame that created this function object.
-
-Size is 3 words.
-
-Type 5: Frame
-
-Header
-Function
-Caller
-Return address
-
-The activation frame is created when a function is invoked to hold its linkages and state.
-
-The capacity is the number of slots, including the inputs, variables, temporaries, and the four words of overhead. A frame, unlike the other types, is never stone.
-
-The function is the address of the function object being called.
-
-The caller is the address of the frame that is invoking the function.
-
-The return address is the address of the instruction in the code that should be executed upon return.
-
-Next come the input arguments, if any.
-
-Then the variables closed over by the inner functions.
-
-Then the variables that are not closed over, followed by the temporaries.
-
-When a function returns, the caller is set to zero. This is a signal to the memory reclaimer that the frame can be reduced.
-
-Type 6: Code
-
-Header
-Arity
-Size
-Closure size
-Entry point
-Disruption point
-
-A code object exists in the actor's immutable memory. A code object never exists in mutable memory.
-
-A code object has a zero capacity and is always stone.
-
-The arity is the maximum number of inputs.
-
-The size is the capacity of an activation frame that will execute this code.
-
-The closure size is a reduced capacity for returned frames that survive memory reclamation.
-
-The entry point is the address at which to begin execution.
-
-The disruption point is the address of the disruption clause.
-
-### opaque C objects
-Records can have opaque C data attached to them.
-
-A C class can register a GC clean up, and a GC trace function. The trace function is called when the record is encountered in the live object graph; and it should mark any values it wants to keep alive in that function.
-
-The system maintains an array of live opaque C objects. When such an object is encountered, it marks it as live in the array. When the GC completes, it iterates this array and calls the GC clean up function for each C object in the array with alive=0. Alive is then cleared for the next GC cycle.
-
-## 32 bit build
-~3 bit type
-1 bit stone
-1 bit memory reclamation flag
-27 bit capacity
-
-Key differences here are
-
-blob max capacity is 2**27 bits = 2**24 bytes = 16 MB [this likely needs addressed]
-
-fwd is type ...0, and the pointer is 31 bits
-other types are
-111 array
-101 object
-011 blob
-001 
-
-## Memory
-Cell uses a single block of memory that it doles out as needed to the actors in its system.
-
-Actors are given a block of memory in standard sizes using a doubling buddy memory manager. An actor is given an immutable data section on birth, as well as a mutable data section. When its mutable data becomes full, it requests a new one. Actors utilize their mutable memory with a simple bump allocation. If there is not sufficient memory available, the actor suspends and its status changes to exhausted.
-
-The smallest block size is determined per platform, but it can be as small as 4KB on 64 bit systems.
-
-The actor is then given a new block of memory of the same size, and it runs a garbage collector to reclaim memory. It uses the cheney copying algorithm. If a disappointing amount of memory was reclaimed, it is noted, and the actor is given a larger block of memory on the next request.

+description: "Network Object Transfer Arrangement"
+weight: 85
+type: "docs"
+---
+
+Nota is a binary message format developed for use in the Procession Protocol. It provides a compact, JSON-like encoding that supports blobs, text, arrays, records, numbers, and symbols. Nota is an internal module: `use('internal/nota')`.
+
+Nota stands for Network Object Transfer Arrangement.
+
+## Design Philosophy
+
+JSON had three design rules: minimal, textual, and subset of JavaScript. The textual and JavaScript rules are no longer necessary. Nota maintains JSON's philosophy of being at the intersection of most programming languages and most data types, but departs by using counts instead of brackets and binary encoding instead of text.
+
+Nota uses Kim continuation bytes for counts and character encoding. See [Kim Encoding](#kim) for details.
+
+## Type Summary
+
+| Bits | Type |
+|------|------|
+| `000` | Blob |
+| `001` | Text |
+| `010` | Array |
+| `011` | Record |
+| `100` | Floating Point (positive exponent) |
+| `101` | Floating Point (negative exponent) |
+| `110` | Integer (zero exponent) |
+| `111` | Symbol |
+
+## Preambles
+
+Every Nota value starts with a preamble byte that is a Kim value with the three most significant bits used for type information.
+
+Most types provide 3 or 4 data bits in the preamble. If the Kim encoding of the data fits in those bits, it is incorporated directly and the continue bit is off. Otherwise the continue bit is on and the continuation follows.
+
+## Blob
+
+```
+C  0  0  0  D  D  D  D
+```
+
+- **C** — continue the number of bits
+- **DDDD** — the number of bits
+
+A blob is a string of bits. The data produces the number of bits. The number of bytes that follow: `floor((number_of_bits + 7) / 8)`. The final byte is padded with 0 if necessary.
+
+Example: A blob containing 25 bits `1111000011100011001000001`:
+
+```
+80 19 F0 E3 20 80
+```
+
+## Text
+
+```
+C  0  0  1  D  D  D  D
+```
+
+- **C** — continue the number of characters
+- **DDDD** — the number of characters
+
+The data produces the number of characters. Kim-encoded characters follow. ASCII characters are 1 byte, first quarter BMP characters are 2 bytes, all other Unicode characters are 3 bytes. Unlike JSON, there is never a need for escapement.
+
+Examples:
+
+```
+""          →  10
+"cat"       →  13 63 61 74
+```
+
+## Array
+
+```
+C  0  1  0  D  D  D  D
+```
+
+- **C** — continue the number of elements
+- **DDDD** — the number of elements
+
+An array is an ordered sequence of values. Following the preamble are the elements, each beginning with its own preamble. Nesting is encouraged.
+
+## Record
+
+```
+C  0  1  1  D  D  D  D
+```
+
+- **C** — continue the number of pairs
+- **DDDD** — the number of pairs
+
+A record is an unordered collection of key/value pairs. Keys must be text and must be unique within the record. Values can be any Nota type.
+
+## Floating Point
+
+```
+C  1  0  E  S  D  D  D
+```
+
+- **C** — continue the exponent
+- **E** — sign of the exponent
+- **S** — sign of the coefficient
+- **DDD** — three bits of the exponent
+
+Nota floating point represents numbers as `coefficient * 10^exponent`. The coefficient must be an integer. The preamble may contain the first three bits of the exponent, followed by the continuation of the exponent (if any), followed by the coefficient.
+
+Use the integer type when the exponent is zero.
+
+Examples:
+
+```
+-1.01                →  5A 65
+98.6                 →  51 87 5A
+-0.5772156649        →  D8 0A 95 C0 B0 BD 69
+-10000000000000      →  C8 0D 01
+```
+
+## Integer
+
+```
+C  1  1  0  S  D  D  D
+```
+
+- **C** — continue the integer
+- **S** — sign
+- **DDD** — three bits of the integer
+
+Integers in the range -7 to 7 fit in a single byte. Integers in the range -1023 to 1023 fit in two bytes. Integers in the range -131071 to 131071 fit in three bytes.
+
+Examples:
+
+```
+0      →  60
+2023   →  E0 8F 67
+-1     →  69
+```
+
+## Symbol
+
+```
+0  1  1  1  D  D  D  D
+```
+
+- **DDDD** — the symbol
+
+There are currently five symbols:
+
+```
+null     →  70
+false    →  72
+true     →  73
+private  →  78
+system   →  79
+```
+
+The private prefix must be followed by a record containing a private process address. The system prefix must be followed by a record containing a system message. All other symbols are reserved.

+title: "Requestors"
+description: "Asynchronous work with requestors"
+weight: 25
+type: "docs"
+---
+
+Requestors are functions that encapsulate asynchronous work. They provide a structured way to compose callbacks, manage cancellation, and coordinate concurrent operations between actors.
+
+## What is a Requestor
+
+A requestor is a function with this signature:
+
+```javascript
+var my_requestor = function(callback, value) {
+  // Do async work, then call callback with result
+  // Return a cancel function
+}
+```
+
+- **callback** — called when the work completes: `callback(value, reason)`
+  - On success: `callback(result)` or `callback(result, null)`
+  - On failure: `callback(null, reason)` where reason explains the failure
+- **value** — input passed from the previous step (or the initial caller)
+- **return** — a cancel function, or null if cancellation is not supported
+
+The cancel function, when called, should abort the in-progress work.
+
+## Writing a Requestor
+
+```javascript
+var fetch_data = function(callback, url) {
+  $contact(function(connection) {
+    send(connection, {get: url}, function(response) {
+      callback(response)
+    })
+  }, {host: url, port: 80})
+  return function() {
+    // clean up if needed
+  }
+}
+```
+
+A requestor that always succeeds immediately:
+
+```javascript
+var constant = function(callback, value) {
+  callback(42)
+}
+```
+
+A requestor that always fails:
+
+```javascript
+var broken = function(callback, value) {
+  callback(null, "something went wrong")
+}
+```
+
+## Composing Requestors
+
+ƿit provides four built-in functions for composing requestors into pipelines.
+
+### sequence(requestor_array)
+
+Run requestors one after another. Each result becomes the input to the next. The final result is passed to the callback.
+
+```javascript
+var pipeline = sequence([
+  fetch_user,
+  validate_permissions,
+  load_profile
+])
+
+pipeline(function(profile, reason) {
+  if (reason) {
+    print(reason)
+  } else {
+    print(profile.name)
+  }
+}, user_id)
+```
+
+If any step fails, the remaining steps are skipped and the failure propagates.
+
+### parallel(requestor_array, throttle, need)
+
+Start all requestors concurrently. Results are collected into an array matching the input order.
+
+```javascript
+var both = parallel([
+  fetch_profile,
+  fetch_settings
+])
+
+both(function(results, reason) {
+  var profile = results[0]
+  var settings = results[1]
+}, user_id)
+```
+
+- **throttle** — limit how many requestors run at once (null for no limit)
+- **need** — minimum number of successes required (default: all)
+
+### race(requestor_array, throttle, need)
+
+Like `parallel`, but returns as soon as the needed number of results arrive. Unfinished requestors are cancelled.
+
+```javascript
+var fastest = race([
+  fetch_from_cache,
+  fetch_from_network,
+  fetch_from_backup
+])
+
+fastest(function(results) {
+  // results[0] is whichever responded first
+}, request)
+```
+
+Default need is 1. Useful for redundant operations where only one result matters.
+
+### fallback(requestor_array)
+
+Try each requestor in order. If one fails, try the next. Return the first success.
+
+```javascript
+var resilient = fallback([
+  fetch_from_primary,
+  fetch_from_secondary,
+  use_cached_value
+])
+
+resilient(function(data, reason) {
+  if (reason) {
+    print("all sources failed")
+  }
+}, key)
+```
+
+## Timeouts
+
+Wrap any requestor with `$time_limit` to add a timeout:
+
+```javascript
+var timed = $time_limit(fetch_data, 5)  // 5 second timeout
+
+timed(function(result, reason) {
+  // reason will explain timeout if it fires
+}, url)
+```
+
+If the requestor does not complete within the time limit, it is cancelled and the callback receives a failure.
+
+## Requestors and Actors
+
+Requestors are particularly useful with actor messaging. Since `send` is callback-based, it fits naturally:
+
+```javascript
+var ask_worker = function(callback, task) {
+  send(worker, task, function(reply) {
+    callback(reply)
+  })
+}
+
+var pipeline = sequence([
+  ask_worker,
+  process_result,
+  store_result
+])
+
+pipeline(function(stored) {
+  print("done")
+  $stop()
+}, {type: "compute", data: [1, 2, 3]})
+```

+title: "Semantic Index"
+description: "Index and query symbols, references, and call sites in source files"
+weight: 55
+type: "docs"
+---
+
+ƿit includes a semantic indexer that extracts symbols, references, call sites, and imports from source files. The index powers the LSP (find references, rename) and is available as a CLI tool for scripting and debugging.
+
+## Overview
+
+The indexer walks the parsed AST without modifying it. It produces a JSON structure that maps every declaration, every reference to that declaration, and every call site in a file.
+
+```
+source → tokenize → parse → fold → index
+                                      ↓
+                              symbols, references,
+                              call sites, imports,
+                              exports, reverse refs
+```
+
+Two CLI commands expose this:
+
+| Command | Purpose |
+|---------|---------|
+| `pit index <file>` | Produce the full semantic index as JSON |
+| `pit explain` | Query the index for a specific symbol or position |
+
+## pit index
+
+Index a source file and print the result as JSON.
+
+```bash
+pit index <file.ce|file.cm>
+pit index <file> -o output.json
+```
+
+### Output
+
+The index contains these sections:
+
+| Section | Description |
+|---------|-------------|
+| `imports` | All `use()` calls with local name, module path, resolved filesystem path, and span |
+| `symbols` | Every declaration: vars, defs, functions, params |
+| `references` | Every use of a name, classified as read, write, or call |
+| `call_sites` | Every function call with callee, args count, and enclosing function |
+| `exports` | For `.cm` modules, the keys of the top-level `return` record |
+| `reverse_refs` | Inverted index: name to list of reference spans |
+
+### Example
+
+Given a file `graph.ce` with functions `make_node`, `connect`, and `build_graph`:
+
+```bash
+pit index graph.ce
+```
+
+```json
+{
+  "version": 1,
+  "path": "graph.ce",
+  "is_actor": true,
+  "imports": [
+    {"local_name": "json", "module_path": "json", "resolved_path": ".cell/packages/core/json.cm", "span": {"from_row": 2, "from_col": 0, "to_row": 2, "to_col": 22}}
+  ],
+  "symbols": [
+    {
+      "symbol_id": "graph.ce:make_node:fn",
+      "name": "make_node",
+      "kind": "fn",
+      "params": ["name", "kind"],
+      "doc_comment": "// A node in the graph.",
+      "decl_span": {"from_row": 6, "from_col": 0, "to_row": 8, "to_col": 1},
+      "scope_fn_nr": 0
+    }
+  ],
+  "references": [
+    {"node_id": 20, "name": "make_node", "ref_kind": "call", "span": {"from_row": 17, "from_col": 13, "to_row": 17, "to_col": 22}}
+  ],
+  "call_sites": [
+    {"node_id": 20, "callee": "make_node", "args_count": 2, "span": {"from_row": 17, "from_col": 22, "to_row": 17, "to_col": 40}}
+  ],
+  "exports": [],
+  "reverse_refs": {
+    "make_node": [
+      {"node_id": 20, "ref_kind": "call", "span": {"from_row": 17, "from_col": 13, "to_row": 17, "to_col": 22}}
+    ]
+  }
+}
+```
+
+### Symbol Kinds
+
+| Kind | Description |
+|------|-------------|
+| `fn` | Function (var or def with function value) |
+| `var` | Mutable variable |
+| `def` | Constant |
+| `param` | Function parameter |
+
+Each symbol has a `symbol_id` in the format `filename:name:kind` and a `decl_span` with `from_row`, `from_col`, `to_row`, `to_col` (0-based).
+
+### Reference Kinds
+
+| Kind | Description |
+|------|-------------|
+| `read` | Value is read |
+| `write` | Value is assigned |
+| `call` | Used as a function call target |
+
+### Module Exports
+
+For `.cm` files, the indexer detects the top-level `return` statement. If it returns a record literal, each key becomes an export linked to its symbol:
+
+```javascript
+// math_utils.cm
+var add = function(a, b) { return a + b }
+var sub = function(a, b) { return a - b }
+return {add: add, sub: sub}
+```
+
+```bash
+pit index math_utils.cm
+```
+
+The `exports` section will contain:
+
+```json
+[
+  {"name": "add", "symbol_id": "math_utils.cm:add:fn"},
+  {"name": "sub", "symbol_id": "math_utils.cm:sub:fn"}
+]
+```
+
+## pit explain
+
+Query the semantic index for a specific symbol or cursor position. This is the targeted query interface — instead of dumping the full index, it answers a specific question.
+
+```bash
+pit explain --span <file>:<line>:<col>
+pit explain --symbol <name> <file>...
+```
+
+### --span: What is at this position?
+
+Point at a line and column (0-based) to find out what symbol or reference is there.
+
+```bash
+pit explain --span demo.ce:6:4
+```
+
+If the position lands on a declaration, that symbol is returned along with all its references and call sites. If it lands on a reference, the indexer traces back to the declaration and returns the same information.
+
+The result includes:
+
+| Field | Description |
+|-------|-------------|
+| `symbol` | The resolved declaration (name, kind, params, doc comment, span) |
+| `reference` | The reference at the cursor, if the cursor was on a reference |
+| `references` | All references to this symbol across the file |
+| `call_sites` | All call sites for this symbol |
+| `imports` | The file's imports (for context) |
+
+```json
+{
+  "symbol": {
+    "name": "build_graph",
+    "symbol_id": "demo.ce:build_graph:fn",
+    "kind": "fn",
+    "params": [],
+    "doc_comment": "// Build a sample graph and return it."
+  },
+  "references": [
+    {"node_id": 71, "ref_kind": "call", "span": {"from_row": 39, "from_col": 12, "to_row": 39, "to_col": 23}}
+  ],
+  "call_sites": []
+}
+```
+
+### --symbol: Find a symbol by name
+
+Look up a symbol by name. Pass one file for a focused result, or multiple files (including shell globs) to search across them all:
+
+```bash
+pit explain --symbol connect demo.ce
+pit explain --symbol connect *.ce *.cm
+```
+
+```json
+{
+  "symbols": [
+    {
+      "name": "connect",
+      "symbol_id": "demo.ce:connect:fn",
+      "kind": "fn",
+      "params": ["from", "to", "label"],
+      "doc_comment": "// Connect two nodes with a labeled edge."
+    }
+  ],
+  "references": [
+    {"node_id": 29, "ref_kind": "call", "span": {"from_row": 21, "from_col": 2, "to_row": 21, "to_col": 9}},
+    {"node_id": 33, "ref_kind": "call", "span": {"from_row": 22, "from_col": 2, "to_row": 22, "to_col": 9}},
+    {"node_id": 37, "ref_kind": "call", "span": {"from_row": 23, "from_col": 2, "to_row": 23, "to_col": 9}}
+  ],
+  "call_sites": [
+    {"callee": "connect", "args_count": 3, "span": {"from_row": 21, "from_col": 9, "to_row": 21, "to_col": 29}},
+    {"callee": "connect", "args_count": 3, "span": {"from_row": 22, "from_col": 9, "to_row": 22, "to_col": 31}},
+    {"callee": "connect", "args_count": 3, "span": {"from_row": 23, "from_col": 9, "to_row": 23, "to_col": 29}}
+  ]
+}
+```
+
+This tells you: `connect` is a function taking `(from, to, label)`, declared on line 11, and called 3 times inside `build_graph`.
+
+## Programmatic Use
+
+The index and explain modules can be used directly from ƿit scripts:
+
+### Via shop (recommended)
+
+```javascript
+var shop = use('internal/shop')
+var idx = shop.index_file(path)
+```
+
+`shop.index_file` runs the full pipeline (tokenize, parse, index, resolve imports) and caches the result.
+
+### index.cm (direct)
+
+If you already have a parsed AST and tokens, use `index_ast` directly:
+
+```javascript
+var index_mod = use('index')
+var idx = index_mod.index_ast(ast, tokens, filename)
+```
+
+### explain.cm
+
+```javascript
+var explain_mod = use('explain')
+var expl = explain_mod.make(idx)
+
+// What is at line 10, column 5?
+var result = expl.at_span(10, 5)
+
+// Find all symbols named "connect"
+var result = expl.by_symbol("connect")
+
+// Get callers and callees of a symbol
+var chain = expl.call_chain("demo.ce:connect:fn", 2)
+```
+
+For cross-file queries:
+
+```javascript
+var result = explain_mod.explain_across([idx1, idx2, idx3], "connect")
+```
+
+## LSP Integration
+
+The semantic index powers these LSP features:
+
+| Feature | LSP Method | Description |
+|---------|------------|-------------|
+| Find References | `textDocument/references` | All references to the symbol under the cursor |
+| Rename | `textDocument/rename` | Rename a symbol and all its references |
+| Prepare Rename | `textDocument/prepareRename` | Validate that the cursor is on a renameable symbol |
+| Go to Definition | `textDocument/definition` | Jump to a symbol's declaration (index-backed with AST fallback) |
+
+These work automatically in any editor with ƿit LSP support. The index is rebuilt on every file change.
+
+## LLM / AI Assistance
+
+The semantic index is designed to give LLMs the context they need to read and edit ƿit code accurately. ƿit is not in any training set, so an LLM cannot rely on memorized patterns — it needs structured information about names, scopes, and call relationships. The commands below are the recommended way to provide that.
+
+### Understand a file before editing
+
+Before modifying a file, index it to see its structure:
+
+```bash
+pit index file.ce
+```
+
+This gives the LLM every declaration, every reference, every call site, and the import list with resolved paths. Key things to extract:
+
+- **`symbols`** — what functions exist, their parameters, and their doc comments. This is enough to understand the file's API without reading every line.
+- **`imports`** with `resolved_path` — which modules are used, and where they live on disk. The LLM can follow these paths to read dependency source when it needs to understand a called function. Imports without a `resolved_path` are C built-ins (like `json`) with no script source to read.
+- **`exports`** — for `.cm` modules, what the public API is. This tells the LLM what names other files can access.
+
+### Investigate a specific symbol
+
+When the LLM needs to rename, refactor, or understand a specific function:
+
+```bash
+pit explain --symbol update analysis.cm
+```
+
+This returns the declaration (with doc comment and parameter list), every reference, and every call site. The LLM can use this to:
+
+- **Rename safely** — the references list has exact spans for every use of the name.
+- **Understand callers** — `call_sites` shows where and how the function is called, including argument counts.
+- **Read the doc comment** — often enough to understand intent without reading the function body.
+
+### Investigate a cursor position
+
+When the LLM is looking at a specific line and column (e.g., from an error message or a user selection):
+
+```bash
+pit explain --span file.ce:17:4
+```
+
+This resolves whatever is at that position — declaration or reference — back to the underlying symbol, then returns all references and call sites. Useful for "what is this name?" queries.
+
+### Search across files
+
+To find a symbol across multiple files, pass them all:
+
+```bash
+pit explain --symbol connect *.ce *.cm
+pit explain --symbol send server.ce client.ce protocol.cm
+```
+
+This indexes each file and searches across all of them. The result merges all matching declarations, references, and call sites. Use this when the LLM needs to understand cross-file usage before making a change that touches multiple files.
+
+### Import resolution
+
+Every import in the index includes the original `module_path` (the string passed to `use()`). For script modules, it also includes `resolved_path` — the filesystem path the module resolves to. This lets the LLM follow dependency chains:
+
+```json
+{"local_name": "fd", "module_path": "fd", "resolved_path": ".cell/packages/core/fd.cm"}
+{"local_name": "json", "module_path": "json"}
+```
+
+An import without `resolved_path` is a C built-in — no script source to read.
+
+### Recommended workflow
+
+1. **Start with `pit index`** on the file to edit. Scan imports and symbols for an overview.
+2. **Use `pit explain --symbol`** to drill into any function the LLM needs to understand or modify. The doc comment and parameter list are usually sufficient.
+3. **Follow `resolved_path`** on imports when the LLM needs to understand a dependency — index or read the resolved file.
+4. **Before renaming**, use `pit explain --symbol` (or `--span`) to get all reference spans, then apply edits to each span.
+5. **For cross-file changes**, pass all affected files to `pit explain --symbol` to see the full picture before editing.

+title: "Shop Architecture"
+description: "How the shop resolves, compiles, caches, and loads modules"
+weight: 35
+type: "docs"
+---
+
+The shop is the module resolution and loading engine behind `use()`. It handles finding modules, compiling them, caching the results, and loading C extensions. The shop lives in `internal/shop.cm`.
+
+## Startup Pipeline
+
+When `pit` runs a program, startup takes one of two paths:
+
+### Fast path (warm cache)
+
+```
+C runtime → engine.cm (from cache) → shop.cm → user program
+```
+
+The C runtime hashes the source of `internal/engine.cm` with BLAKE2 and looks up the hash in the content-addressed cache (`~/.cell/build/<hash>`). On a cache hit, engine.cm loads directly — no bootstrap involved.
+
+### Cold path (first run or cache cleared)
+
+```
+C runtime → bootstrap.cm → (seeds cache) → engine.cm (from cache) → shop.cm → user program
+```
+
+On a cache miss, the C runtime loads `boot/bootstrap.cm.mcode` (a pre-compiled seed). Bootstrap compiles engine.cm and the pipeline modules (tokenize, parse, fold, mcode, streamline) from source and caches the results. The C runtime then retries the engine cache lookup, which now succeeds.
+
+### Engine
+
+**engine.cm** is self-sufficient. It loads its own compilation pipeline from the content-addressed cache, with fallback to the pre-compiled seeds in `boot/`. It defines `analyze()` (source to AST), `compile_to_blob()` (AST to binary blob), and `use_core()` for loading core modules. It creates the actor runtime and loads shop.cm via `use_core('internal/shop')`.
+
+### Shop
+
+**shop.cm** receives its dependencies through the module environment — `analyze`, `run_ast_fn`, `use_cache`, `shop_path`, `runtime_env`, `content_hash`, `cache_path`, and others. It defines `Shop.use()`, which is the function behind every `use()` call in user code.
+
+### Cache invalidation
+
+All caching is content-addressed by BLAKE2 hash of the source. When any source file changes, its hash changes and the old cache entry is simply never looked up again. No manual invalidation is needed. To force a full rebuild, delete `~/.cell/build/`.
+
+## Module Resolution
+
+When `use('path')` is called from a package context, the shop resolves the module through a multi-layer search. Both the `.cm` script file and C symbol are resolved independently, and the one with the narrowest scope wins.
+
+### Resolution Order
+
+For a call like `use('sprite')` from package `myapp`:
+
+1. **Own package** — `~/.cell/packages/myapp/sprite.cm` and C symbol `js_myapp_sprite_use`
+2. **Aliased dependencies** — if `myapp/cell.toml` has `renderer = "gitea.pockle.world/john/renderer"`, checks `renderer/sprite.cm` and its C symbols
+3. **Core** — built-in core modules and internal C symbols
+
+For calls without a package context (from core modules), only core is searched.
+
+### Private Modules
+
+Paths starting with `internal/` are private to their package:
+
+```javascript
+use('internal/helpers')  // OK from within the same package
+// Cannot be accessed from other packages
+```
+
+### Explicit Package Imports
+
+Paths containing a dot in the first component are treated as explicit package references:
+
+```javascript
+use('gitea.pockle.world/john/renderer/sprite')
+// Resolves directly to the renderer package's sprite.cm
+```
+
+## Compilation and Caching
+
+Every module goes through a content-addressed caching pipeline. Cache keys are based on the inputs that affect the output artifact, so changing any relevant input automatically invalidates the cache.
+
+### Cache Hierarchy
+
+When loading a module, the shop checks (in order):
+
+1. **In-memory cache** — `use_cache[key]`, checked first on every `use()` call
+2. **Build-cache dylib** — content-addressed `.dylib` in `~/.cell/build/<hash>`, found via manifest (see [Dylib Manifests](#dylib-manifests))
+3. **Cached bytecode** — content-addressed in `~/.cell/build/<hash>` (no extension)
+4. **Internal symbols** — statically linked into the `cell` binary (fat builds)
+5. **Source compilation** — full pipeline: analyze, mcode, streamline, serialize
+
+Dylib resolution wins over internal symbols, so a built dylib can hot-patch a fat binary. Results from compilation are cached back to the content-addressed store for future loads.
+
+Each loading method (except the in-memory cache) can be individually enabled or disabled via `shop.toml` policy flags — see [Shop Configuration](#shop-configuration) below.
+
+### Content-Addressed Store
+
+The build cache at `~/.cell/build/` stores all compiled artifacts named by the BLAKE2 hash of their inputs:
+
+```
+~/.cell/build/
+├── a1b2c3d4...          # cached bytecode blob, object file, dylib, or manifest (no extension)
+└── ...
+```
+
+Every artifact type uses a unique salt appended to the content before hashing, so collisions between different artifact types are impossible:
+
+| Salt | Artifact |
+|------|----------|
+| `obj` | compiled C object file |
+| `dylib` | linked dynamic library |
+| `native` | native-compiled .cm dylib |
+| `mach` | mach bytecode blob |
+| `mcode` | mcode IR (JSON) |
+| `deps` | cached `cc -MM` dependency list |
+| `fail` | cached compilation failure marker |
+| `manifest` | package dylib manifest (JSON) |
+
+This scheme provides automatic cache invalidation: when source changes, its hash changes, and the old cache entry is simply never looked up again.
+
+### Failure Caching
+
+When a C file fails to compile (missing SDK headers, syntax errors, etc.), the build system writes a failure marker to the cache using the `fail` salt. On subsequent builds, the failure marker is found and the file is skipped immediately — no time wasted retrying files that can't compile. The failure marker is keyed on the same content as the compilation (command string + source content), so if the source changes or compiler flags change, the failure is automatically invalidated and compilation is retried.
+
+### Dylib Manifests
+
+Dylibs live at content-addressed paths (`~/.cell/build/<hash>`) that can only be computed by running the full build pipeline. To allow the runtime to find pre-built dylibs without invoking the build module, `cell build` writes a **manifest** for each package. The manifest is a JSON file mapping each C module to its `{file, symbol, dylib}` entry. The manifest path is itself content-addressed (BLAKE2 hash of the package name + `manifest` salt), so the runtime can compute it from the package name alone.
+
+At runtime, when `use()` needs a C module from another package, the shop reads the manifest to find the dylib path. This means `cell build` must be run before C modules from packages can be loaded.
+
+For native `.cm` dylibs, the cache content includes source, target, native mode marker, and sanitize flags, then uses the `native` salt. Changing any of those inputs produces a new cache path automatically.
+
+### Core Module Caching
+
+Core modules loaded via `use_core()` in engine.cm follow the same content-addressed pattern. On first use, a module is compiled from source and cached by the BLAKE2 hash of its source content. Subsequent loads with unchanged source hit the cache directly.
+
+User scripts (`.ce` files) are also cached. The first run compiles and caches; subsequent runs with unchanged source load from cache.
+
+## C Extension Resolution
+
+C extensions are resolved alongside script modules. A C module is identified by a symbol name derived from the package and file name:
+
+```
+package: gitea.pockle.world/john/prosperon
+file:    sprite.c
+symbol:  js_gitea_pockle_world_john_prosperon_sprite_use
+```
+
+### C Resolution Sources
+
+1. **Build-cache dylibs** — content-addressed dylibs in `~/.cell/build/<hash>`, found via per-package manifests written by `cell build`
+2. **Internal symbols** — statically linked into the `cell` binary (fat builds)
+
+Dylibs are checked first at each resolution scope, so a built dylib always wins over a statically linked symbol. This enables hot-patching fat binaries.
+
+### Name Collisions
+
+Having both a `.cm` script and a `.c` file with the same stem at the same scope is a **build error**. For example, `render.cm` and `render.c` in the same directory will fail. Use distinct names — e.g., `render.c` for the C implementation and `render_utils.cm` for the script wrapper.
+
+## Environment Injection
+
+When a module is loaded, the shop builds an `env` object that becomes the module's set of free variables. This includes:
+
+- **Runtime functions** — `logical`, `some`, `every`, `starts_with`, `ends_with`, `is_actor`, `log`, `send`, `fallback`, `parallel`, `race`, `sequence`
+- **Capability injections** — actor intrinsics like `$self`, `$delay`, `$start`, `$receiver`, `$fd`, etc.
+- **`use` function** — scoped to the module's package context
+
+The set of injected capabilities is controlled by `script_inject_for()`, which can be tuned per package or file.
+
+## Shop Configuration
+
+The shop reads an optional `shop.toml` file from the shop root (`~/.cell/shop.toml`). This file controls which loading methods are permitted through policy flags.
+
+### Policy Flags
+
+All flags default to `true`. Set a flag to `false` to disable that loading method.
+
+```toml
+[policy]
+allow_dylib = true     # per-file .dylib loading (requires dlopen)
+allow_static = true    # statically linked C symbols (fat builds)
+allow_mach = true      # pre-compiled .mach bytecode (lib/ and build cache)
+allow_compile = true   # on-the-fly source compilation
+```
+
+### Example Configurations
+
+**Production lockdown** — only use pre-compiled artifacts, never compile from source:
+
+```toml
+[policy]
+allow_compile = false
+```
+
+**Pure-script mode** — bytecode only, no native code:
+
+```toml
+[policy]
+allow_dylib = false
+allow_static = false
+```
+
+**No dlopen platforms** — static linking and bytecode only:
+
+```toml
+[policy]
+allow_dylib = false
+```
+
+If `shop.toml` is missing or has no `[policy]` section, all methods are enabled (default behavior).
+
+## Shop Directory Layout

+```

+title: "C Runtime for Native Code"
+description: "Minimum C runtime surface for QBE-generated native code"
+---
+
+## Overview
+
+QBE-generated native code calls into a C runtime for anything that touches the heap, dispatches dynamically, or requires GC awareness. The design principle: **native code handles control flow and integer math directly; everything else is a runtime call.**
+
+This document defines the runtime boundary — what must be in C, what QBE handles inline, and how to organize the C code to serve both the mcode interpreter and native code cleanly.
+
+## The Boundary
+
+### What native code does inline (no C calls)
+
+These operations compile to straight QBE instructions with no runtime involvement:
+
+- **Integer arithmetic**: `add`, `sub`, `mul` on NaN-boxed ints (shift right 1, operate, shift left 1)
+- **Integer comparisons**: extract int with shift, compare, produce tagged bool
+- **Control flow**: jumps, branches, labels, function entry/exit
+- **Slot access**: load/store to frame slots via `%fp` + offset
+- **NaN-box tagging**: integer tagging (`n << 1`), bool constants (`0x03`/`0x23`), null (`0x07`)
+- **Type tests**: `JS_IsInt` (LSB check), `JS_IsNumber`, `JS_IsText`, `JS_IsNull` — these are bit tests on the value, no heap access needed
+
+### What requires a C call
+
+Anything that:
+1. **Allocates** (arrays, records, strings, frames, function objects)
+2. **Touches the heap** (property get/set, array indexing, closure access)
+3. **Dispatches on type at runtime** (dynamic load/store, polymorphic arithmetic)
+4. **Calls user functions** (frame setup, argument passing, invocation)
+5. **Does string operations** (concatenation, comparison, conversion)
+
+## Runtime Functions
+
+### Tier 1: Essential (must exist for any program to run)
+
+These are called by virtually every QBE program.
+
+#### Intrinsic Lookup
+
+```c
+// Look up a built-in function by name. Called once per intrinsic per callsite.
+JSValue cell_rt_get_intrinsic(JSContext *ctx, const char *name);
+```
+
+Maps name → C function pointer wrapped in JSValue. This is the primary entry point for all built-in functions (`print`, `text`, `length`, `is_array`, etc). The native code never calls intrinsics directly — it always goes through `get_intrinsic` → `frame` → `invoke`.
+
+#### Function Calls
+
+```c
+// Allocate a call frame with space for nr_args arguments.
+JSValue cell_rt_frame(JSContext *ctx, JSValue fn, int nr_args);
+
+// Set argument idx in the frame.
+void cell_rt_setarg(JSValue frame, int idx, JSValue val);
+
+// Execute the function. Returns the result.
+JSValue cell_rt_invoke(JSContext *ctx, JSValue frame);
+```
+
+This is the universal calling convention. Every function call — user functions, intrinsics, methods — goes through frame/setarg/invoke. The frame allocates a `JSFrameRegister` on the GC heap, setarg fills slots, invoke dispatches.
+
+**Tail call variants:**
+
+```c
+JSValue cell_rt_goframe(JSContext *ctx, JSValue fn, int nr_args);
+void    cell_rt_goinvoke(JSContext *ctx, JSValue frame);
+```
+
+Same as frame/invoke but reuse the caller's stack position.
+
+### Tier 2: Property Access (needed by any program using records or arrays)
+
+```c
+// Record field by constant name.
+JSValue cell_rt_load_field(JSContext *ctx, JSValue obj, const char *name);
+void    cell_rt_store_field(JSContext *ctx, JSValue obj, JSValue val, const char *name);
+
+// Array element by integer index.
+JSValue cell_rt_load_index(JSContext *ctx, JSValue obj, JSValue idx);
+void    cell_rt_store_index(JSContext *ctx, JSValue obj, JSValue idx, JSValue val);
+
+// Dynamic — type of key unknown at compile time.
+JSValue cell_rt_load_dynamic(JSContext *ctx, JSValue obj, JSValue key);
+void    cell_rt_store_dynamic(JSContext *ctx, JSValue obj, JSValue key, JSValue val);
+```
+
+The typed variants (`load_field`/`load_index`) skip the key-type dispatch that `load_dynamic` must do. When parse and fold provide type information, QBE emit selects the typed variant and the streamline optimizer can narrow dynamic → typed.
+
+**Implementation**: These are thin wrappers around existing `JS_GetPropertyStr`/`JS_GetPropertyNumber`/`JS_GetProperty` and their `Set` counterparts.
+
+### Tier 3: Closures (needed by programs with nested functions)
+
+```c
+// Walk depth levels up the frame chain, read slot.
+JSValue cell_rt_get_closure(JSContext *ctx, JSValue fp, int depth, int slot);
+
+// Walk depth levels up, write slot.
+void    cell_rt_put_closure(JSContext *ctx, JSValue fp, JSValue val, int depth, int slot);
+```
+
+Closure variables live in outer frames. `depth` is how many `caller` links to follow; `slot` is the register index in that frame.
+
+### Tier 4: Object Construction (needed by programs creating arrays/records/functions)
+
+```c
+// Create a function object from a compiled function index.
+// The native code loader must maintain a function table.
+JSValue cell_rt_make_function(JSContext *ctx, int fn_id);
+```
+
+Array and record literals are currently compiled as intrinsic calls (`array(...)`, direct `{...}` construction) which go through the frame/invoke path. A future optimization could add:
+
+```c
+// Fast paths (optional, not yet needed)
+JSValue cell_rt_new_array(JSContext *ctx, int len);
+JSValue cell_rt_new_record(JSContext *ctx);
+```
+
+### Tier 5: Collection Operations
+
+```c
+// a[] = val (push) and var v = a[] (pop)
+void    cell_rt_push(JSContext *ctx, JSValue arr, JSValue val);
+JSValue cell_rt_pop(JSContext *ctx, JSValue arr);
+```
+
+### Tier 6: Error Handling
+
+```c
+// Trigger disruption. Jumps to the disrupt handler or unwinds.
+void cell_rt_disrupt(JSContext *ctx);
+```
+
+### Tier 7: Miscellaneous
+
+```c
+JSValue cell_rt_delete(JSContext *ctx, JSValue obj, JSValue key);
+JSValue cell_rt_typeof(JSContext *ctx, JSValue val);
+```
+
+### Tier 8: String and Float Helpers (called from QBE inline code, not from qbe_emit)
+
+These are called from the QBE IL that `qbe.cm` generates inline for arithmetic and comparison operations. They're not `cell_rt_` prefixed — they're lower-level:
+
+```c
+// Float arithmetic (when operands aren't both ints)
+JSValue qbe_float_add(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_float_sub(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_float_mul(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_float_div(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_float_mod(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_float_pow(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_float_neg(JSContext *ctx, JSValue v);
+JSValue qbe_float_inc(JSContext *ctx, JSValue v);
+JSValue qbe_float_dec(JSContext *ctx, JSValue v);
+
+// Float comparison (returns C int 0/1 for QBE branching)
+int qbe_float_cmp(JSContext *ctx, int op, JSValue a, JSValue b);
+
+// Bitwise ops on non-int values (convert to int32 first)
+JSValue qbe_bnot(JSContext *ctx, JSValue v);
+JSValue qbe_bitwise_and(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_bitwise_or(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_bitwise_xor(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_shift_shl(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_shift_sar(JSContext *ctx, JSValue a, JSValue b);
+JSValue qbe_shift_shr(JSContext *ctx, JSValue a, JSValue b);
+
+// String operations
+JSValue JS_ConcatString(JSContext *ctx, JSValue a, JSValue b);
+int     js_string_compare_value(JSContext *ctx, JSValue a, JSValue b, int eq_only);
+JSValue JS_NewString(JSContext *ctx, const char *str);
+JSValue __JS_NewFloat64(JSContext *ctx, double d);
+int     JS_ToBool(JSContext *ctx, JSValue v);
+
+// String/number type tests (inline-able but currently calls)
+int     JS_IsText(JSValue v);
+int     JS_IsNumber(JSValue v);
+
+// Tolerant equality (== on mixed types)
+JSValue cell_rt_eq_tol(JSContext *ctx, JSValue a, JSValue b);
+JSValue cell_rt_ne_tol(JSContext *ctx, JSValue a, JSValue b);
+
+// Text ordering comparisons
+JSValue cell_rt_lt_text(JSContext *ctx, JSValue a, JSValue b);
+JSValue cell_rt_le_text(JSContext *ctx, JSValue a, JSValue b);
+JSValue cell_rt_gt_text(JSContext *ctx, JSValue a, JSValue b);
+JSValue cell_rt_ge_text(JSContext *ctx, JSValue a, JSValue b);
+```
+
+## What Exists vs What Needs Writing
+
+### Already exists (in qbe_helpers.c)
+
+All `qbe_float_*`, `qbe_bnot`, `qbe_bitwise_*`, `qbe_shift_*`, `qbe_to_bool` — these are implemented and working.
+
+### Already exists (in runtime.c / quickjs.c) but not yet wrapped
+
+The underlying operations exist but aren't exposed with the `cell_rt_` names:
+
+| Runtime function | Underlying implementation |
+|---|---|
+| `cell_rt_load_field` | `JS_GetPropertyStr(ctx, obj, name)` |
+| `cell_rt_load_index` | `JS_GetPropertyNumber(ctx, obj, JS_VALUE_GET_INT(idx))` |
+| `cell_rt_load_dynamic` | `JS_GetProperty(ctx, obj, key)` |
+| `cell_rt_store_field` | `JS_SetPropertyStr(ctx, obj, name, val)` |
+| `cell_rt_store_index` | `JS_SetPropertyNumber(ctx, obj, JS_VALUE_GET_INT(idx), val)` |
+| `cell_rt_store_dynamic` | `JS_SetProperty(ctx, obj, key, val)` |
+| `cell_rt_delete` | `JS_DeleteProperty(ctx, obj, key)` |
+| `cell_rt_push` | `JS_ArrayPush(ctx, &arr, val)` |
+| `cell_rt_pop` | `JS_ArrayPop(ctx, arr)` |
+| `cell_rt_typeof` | type tag switch → `JS_NewString` |
+| `cell_rt_disrupt` | `JS_Throw(ctx, ...)` |
+| `cell_rt_eq_tol` / `cell_rt_ne_tol` | comparison logic in mcode.c `eq_tol`/`ne_tol` handler |
+| `cell_rt_lt_text` etc. | `js_string_compare_value` + wrap result |
+
+### Needs new code
+
+| Runtime function | What's needed |
+|---|---|
+| `cell_rt_get_intrinsic` | Look up intrinsic by name string, return JSValue function. Currently scattered across `js_cell_intrinsic_get` and the mcode handler. Needs a clean single entry point. |
+| `cell_rt_frame` | Allocate `JSFrameRegister`, set function slot, set argc. Exists in mcode.c `frame` handler but not as a callable function. |
+| `cell_rt_setarg` | Write to frame slot. Trivial: `frame->slots[idx + 1] = val` (slot 0 is `this`). |
+| `cell_rt_invoke` | Call the function in the frame. Needs to dispatch: native C function vs mach bytecode vs mcode. This is the critical piece — it must handle all function types. |
+| `cell_rt_goframe` / `cell_rt_goinvoke` | Tail call variants. Similar to frame/invoke but reuse caller frame. |
+| `cell_rt_make_function` | Create function object from index. Needs a function table (populated by the native loader). |
+| `cell_rt_get_closure` / `cell_rt_put_closure` | Walk frame chain. Exists inline in mcode.c `get`/`put` handlers. |
+
+## Recommended C File Organization
+
+```
+source/
+  cell_runtime.c    — NEW: all cell_rt_* functions (the native code API)
+  qbe_helpers.c     — existing: float/bitwise/shift helpers for inline QBE
+  runtime.c         — existing: JS_GetProperty, JS_SetProperty, etc.
+  quickjs.c         — existing: core VM, GC, value representation
+  mcode.c           — existing: mcode interpreter (can delegate to cell_runtime.c)
+```
+
+**`cell_runtime.c`** is the single file that defines the native code contract. It should:
+
+1. Include `quickjs-internal.h` for access to value representation and heap types
+2. Export all `cell_rt_*` functions with C linkage (no `static`)
+3. Keep each function thin — delegate to existing `JS_*` functions where possible
+4. Handle GC safety: after any allocation (frame, string, array), callers' frames may have moved
+
+### Implementation Priority
+
+**Phase 1** — Get "hello world" running natively:
+- `cell_rt_get_intrinsic` (to find `print` and `text`)
+- `cell_rt_frame`, `cell_rt_setarg`, `cell_rt_invoke` (to call them)
+- A loader that takes QBE output → assembles → links → calls `cell_main`
+
+**Phase 2** — Variables and arithmetic:
+- All property access (`load_field`, `load_index`, `store_*`, `load_dynamic`)
+- `cell_rt_make_function`, `cell_rt_get_closure`, `cell_rt_put_closure`
+
+**Phase 3** — Full language:
+- `cell_rt_push`, `cell_rt_pop`, `cell_rt_delete`, `cell_rt_typeof`
+- `cell_rt_disrupt`
+- `cell_rt_goframe`, `cell_rt_goinvoke`
+- Text comparison wrappers (`cell_rt_lt_text`, etc.)
+- Tolerant equality (`cell_rt_eq_tol`, `cell_rt_ne_tol`)
+
+## Calling Convention
+
+All `cell_rt_*` functions follow the same pattern:
+
+- First argument is always `JSContext *ctx`
+- Values are passed/returned as `JSValue` (64-bit, by value)
+- Frame pointers are `JSValue` (tagged pointer to `JSFrameRegister`)
+- String names are `const char *` (pointer to data section label)
+- Integer constants (slot indices, arg counts) are `int` / `long`
+
+Native code maintains `%ctx` (JSContext) and `%fp` (current frame pointer) as persistent values across the function body. All slot reads/writes go through `%fp` + offset.
+
+## What Should NOT Be in the C Runtime
+
+These are handled entirely by QBE-generated code:
+
+- **Integer arithmetic and comparisons** — bit operations on NaN-boxed values
+- **Control flow** — branches, loops, labels, jumps
+- **Boolean logic** — `and`/`or`/`not` on tagged values
+- **Constant loading** — integer constants are immediate, strings are data labels
+- **Type guard branches** — the `is_int`/`is_text`/`is_null` checks are inline bit tests; the branch to the float or text path is just a QBE `jnz`
+
+The `qbe.cm` macros already handle all of this. The arithmetic path looks like:
+
+```
+check both ints? → yes → inline int add → done
+                 → no  → call qbe_float_add (or JS_ConcatString for text)
+```
+
+The C runtime is only called on the slow paths (float, text, dynamic dispatch). The fast path (integer arithmetic, comparisons, branching) is fully native.
