For `{#if}`, an optional `{:else}` branch is captured. - -**Static analysis**: `isStaticNode()` recursively checks if a node subtree contains no dynamic expressions — enabling hoisting optimizations. - -### 1.2 SSA IR (`ssa.ts`) - -The SSA pass converts the AST into a flat, ordered list of instructions. Each instruction is an atomic DOM operation: - -| Instruction | Description | -|-------------|-------------| -| `create(tag)` | `document.createElement(tag)` | -| `attr(key, value)` | `el.setAttribute(key, value)` or reactive `effect()` binding | -| `event(type, handler)` | `el.addEventListener(type, handler)` | -| `text(value)` | `document.createTextNode(value)` | -| `expr(expression)` | Creates text node + `effect()` binding to keep it updated | -| `append(parentId, childId)` | `parent.appendChild(child)` | -| `each(source, context)` | Loop with nested instructions as the loop body | -| `if(condition)` | Conditional with nested instructions | - -Each instruction gets a unique target ID (`v0`, `v1`, `v2`, ...).

Scrolling triggers computed signal chains that rebuild the visible cell set. - -2. **Fine-grained reactivity under load**: Each cell's class, background, and text are independent `effect()` subscriptions. When `gridData` changes, only cells with visible changes have their effects re-run — even though thousands of cells are updated in a single frame. - -3. **Batch coalescing prevents jank**: The RAF loop wraps all signal mutations in `batch()`, which uses `queueMicrotask` to coalesce all DOM writes into a single synchronous flush. - -4. **No VDOM overhead**: There is no tree diffing, no reconciliation pass, no VNode allocation. State → signal → effect → DOM is a direct path. - -5. **Sparse data efficiency**: Only ~3-8k cells out of 1M have non-zero values at any time. The `Map` storage is memory-efficient, and the template only iterates `visibleRows/Cols` (not all 1M). - ---- - -## 4.

BOTTLENECK ANALYSIS — RANKED BY IMPACT + +### BOTTLENECK #1: Excessive WASM↔JS Boundary Crossings [CRITICAL] +**Impact: 3-5x speedup on signal.set() hot path** + +**Location:** `signal.ts:162-178`, `arena.ts:132-152` + +**Problem:** `signal.set()` makes **6-8 individual WASM function calls** per invocation: +- `arenaReadTag(id)` — 1 WASM call to read a single byte +- `arenaWriteNum/Str/Bool/Obj` — 1+ WASM calls +- `core.signal_mark_dirty(id)` — 1 WASM call +- `core.batch_depth()` — 1 WASM call +- `core.signal_flush_immediate(id)` — 1 WASM call + internal subs_snapshot +- `getU32View()` — OK (cached) + +Each WASM↔JS boundary crossing costs ~200-500ns. With 6 crossings, that's 1.2-3μs of pure overhead per signal.set(). For a 500k object scene updating 60fps, that's 36M set() calls/frame budget of ~16ms. + +**Proposed Fix:** Create a **single WASM function `signal_set(id, tag, value_f64)`** that does tag check + write + mark dirty + check batch depth all in one call. Returns a packed u32: `(was_changed | (batch_depth << 1) | (effect_count << 16))`. This eliminates 5 of 6 boundary crossings. + +For string signals, create `signal_set_str(id, byte_ptr, byte_len)` that does the JS-side string comparison AND the WASM write in one call. + +**Estimated Gain:** 4-6x throughput on signal.set() (from ~250k/sec to ~1.5M/sec per core). + +**Trade-off:** Slightly larger WASM module. One more exported function. The packed return requires bit manipulation on the JS side. + +--- + +### BOTTLENECK #2: VNode Object Allocation on Every Patch [CRITICAL] +**Impact: Eliminates ~80% of GC pressure during re-rendering** + +**Location:** `vnode.ts:13-24`, `pool.ts:53-64` + +**Problem:** `createVNode()` creates a new object literal `{tag, props, children, key, el}` on every call. The `vnodePool` exists but is **never used by mount.ts or patch.ts**. Every V8 GC cycle during heavy patching pauses for 1-10ms while collecting thousands of VNode objects. + +The `VNode` interface has 5 properties = 5 hidden class transitions. V8 uses hidden classes + inline caches; these objects have different shapes depending on which fields are set. + +**Proposed Fix:** +1. **Flat VNode pool**: Replace object pool with pre-allocated typed arrays: + ``` + const _vnodeTags: (string | null)[] = new Array(8192); + const _vnodeProps: (VNodeProps | null)[] = new Array(8192); + const _vnodeChildren: ((VNode | string)[] | null)[] = new Array(8192); + const _vnodeKeys: (string | number | null)[] = new Array(8192); + const _vnodeEls: (Node | null)[] = new Array(8192); + const _vnodeFreeHead = 0; + ``` +2. **Actually wire vnodePool into mount() and patch()** — currently it's dead code. +3. **Eliminate VNode entirely for static subtrees** — the compiler already marks `isStatic: true`. Static subtrees should be created once and cloned via `cloneNode(true)` on every mount. + +**Estimated Gain:** 2-3x reduction in GC pauses. 30-50% reduction in memory allocation rate. + +--- + +### BOTTLENECK #3: arenaReadRaw Has 4 WASM Round-Trips [HIGH] +**Impact: 4x speedup on signal.get() in hot effects** + +**Location:** `arena.ts:143-152` + +**Problem:** `arenaReadRaw(id)` calls: +1. `arenaReadTag(id)` — 1 WASM call (reads tag byte) +2. `arenaReadNum(id)` OR `arenaReadStr(id)` OR `arenaReadBool(id)` OR `arenaReadObj(id)` — each 1+ WASM calls + +Total: 2 WASM calls minimum per signal.get(). Inside an effect that reads 10 signals, that's 20 WASM calls. + +**Proposed Fix:** +1. **Cache the tag alongside the signal ID in JS.** When `signal()` is called, store the tag in a parallel `Uint8Array`. Reads become `tag = _signalTags[id]; return tag === TAG_NUM ? f64View[id] : ...` +2. **For number signals (the common case ~80%):** `signal.get()` should be `return f64View[id]` — zero WASM calls. This is possible because the f64View is a direct typed view into WASM linear memory. The Zig `wf64` writes directly there, so JS reads are already seeing the latest value. +3. **For string signals:** Keep JS-side `_slotStringMap` cache (already exists). The only WASM call needed is on first read of a string that was written by Zig directly. + +**Estimated Gain:** For number signals: 10-20x faster (from 2 WASM calls to 0). Overall signal.get(): 4-8x faster. + +**Trade-off:** Requires tracking tag type in JS memory (8KB Uint8Array). Slight duplication of tag state between Zig and JS, but Zig is source of truth. + +--- + +### BOTTLENECK #4: Batch Dedup Bitmap is 32KB and Always Touched [MEDIUM] +**Impact: Eliminates 32KB write on every batch** + +**Location:** `signal.ts:65,286-302` + +**Problem:** `_batchSeen` is a `Uint32Array(8192)` = 32KB. On every batch, the code iterates `effCount` entries, checks `seen[eid]`, writes `1`, runs effect, then iterates again to write `0`. For a batch with 50 effects, this touches 50 entries in the bitmap — but the bitmap is 8192 entries. The real cost is the **two-pass cleanup** (once to dedup, once to clear). + +**Proposed Fix:** Replace with a **generation counter** approach: +```typescript +let _batchGen = 0; +const _batchSeenGen = new Uint32Array(8192); + +// In batch(): +_batchGen++; +for (let i = 0; i < effCount; i++) { + const eid = u32[SNAPSHOT_BUF_START + i]; + if (eid < 8192) { + if (_batchSeenGen[eid] !== _batchGen) { + _batchSeenGen[eid] = _batchGen; + _runEffect(eid); + } + } else { + _runEffect(eid); + } +} +// No cleanup pass needed! +``` + +**Estimated Gain:** Eliminates one full pass over the dedup buffer. 2-3x faster batch flush for small-to-medium batches. + +--- + +### BOTTLENECK #5: reconcile Creates New Arrays Every Frame [HIGH] +**Impact: Eliminates all reconcile-time allocations** + +**Location:** `reconcile.ts:19,65` + +**Problem:** +- `newItems: ReconcileItem[] = new Array(newCount)` — allocated every reconcile call +- `_insertOrderBuf` grows but never shrinks +- Each `ReconcileItem` is a `{key, nodes, data}` object allocation + +**Proposed Fix:** +1. Pre-allocate `_newItemsBuf` at module scope, reuse across calls: + ```typescript + let _newItemsBuf: ReconcileItem[] = new Array(1024); + let _newItemsLen = 0; + ``` +2. For `ReconcileItem`, use flat arrays like the VNode suggestion: + ``` + const _riKeys: (string | number)[] = []; + const _riNodes: (Node[])[] = []; + const _riData: unknown[] = []; + ``` +3. Clear `_newItemsBuf` after use by nulling references (prevent memory leaks). + +**Estimated Gain:** Eliminates all dynamic allocation during reconciliation. For 10k item lists: saves ~400KB of allocation per frame. + +--- + +### BOTTLENECK #6: WASM String Copy Byte-By-Byte [MEDIUM] +**Impact: 4-8x faster string allocation** + +**Location:** `wasm-glue.ts:224-227`, `dominator_core.zig:145-151` + +**Problem:** `writeStringToWasm()` in JS copies byte-by-byte: +```typescript +for (let i = 0; i < byteLen; i++) { + u8[(ptr + i) * 4] = bytes[i]; +} +``` +And Zig copies byte-by-byte into the arena: +```zig +while (i < byte_len) : (i += 1) { + const byte_val = ru8(byte_ptr + i); + // ... shift and mask per byte +} +``` +For a 100-character string, that's 100 byte-by-byte operations in JS AND 100 shift+mask operations in Zig. + +**Proposed Fix:** +1. **JS side:** Use `TypedArray.set()` for bulk copy: + ```typescript + const u8 = getU8View(); + // Write to a contiguous temporary region first + u8.set(bytes, ptr * 4); // Single memcpy + ``` +2. **Zig side:** Use `@memcpy` for the string copy loop, or better yet, accept a u32 slice directly: + ```zig + export fn arena_alloc_str_bulk(ptr: [*]const u8, byte_len: u32) u32 { + const id = _arena_size; + _arena_size += 1; + const word_base = DYNAMIC_START + (_string_bytes_used / 4); + // Bulk copy — WASM compilers optimize @memcpy to bulk_memory + @memcpy(heap_bytes[word_base*4..][0..byte_len], ptr[0..byte_len]); + // ... store metadata + } + ``` + +**Estimated Gain:** 4-8x faster string allocation. For short strings (< 32 chars), the benefit is smaller but still measurable. + +--- + +### BOTTLENECK #7: getCore() Null-Check in Hot Paths [MEDIUM] +**Impact: Eliminates branch + null check per WASM call** + +**Location:** `wasm-glue.ts:116-135`, used everywhere + +**Problem:** Every `getCore()` call checks `if (_core) return _core;`. On hot paths like `signal.set()`, `getCore()` is called 3-5 times. The branch predictor handles this well (always taken), but the null check still generates a conditional branch instruction. + +**Proposed Fix:** Replace with a direct field access pattern: +```typescript +let _core: CoreExports; +// After initialization, _core is guaranteed non-null +// Hot paths use _core directly, cold paths use getCore() +``` +In signal.ts, cache the core reference at module init time: +```typescript +let _core: CoreExports; +export function _setCore(c: CoreExports) { _core = c; } +// Then in hot path: +_core.signal_mark_dirty(id); // No null check +``` + +**Estimated Gain:** ~5-10% reduction in instruction count on hot paths. Minor but free. + +--- + +### BOTTLENECK #8: Event Delegation WeakMap Lookup Per Bubble Node [MEDIUM] +**Impact: 2-3x faster event bubbling for deep DOM trees** + +**Location:** `events.ts:56-57` + +**Problem:** During event bubbling, every node in the bubble path triggers: +```typescript +const nodeId = _nodeIds.get(_bubblePath[i]!); // WeakMap.get() — ~200ns +``` +For a DOM tree with average depth 10, that's 10 WeakMap lookups per event. WeakMap.get() is implemented as a hash table lookup with key hashing — much slower than array indexing. + +**Proposed Fix:** +1. **Add a `node.__dominator_id` property** instead of WeakMap: + ```typescript + function _getNodeId(node: Node): number { + const existing = (node as any).__dominator_id; + if (existing !== undefined) return existing; + const id = _nextNodeId++; + (node as any).__dominator_id = id; + return id; + } + ``` + Direct property access is ~10ns vs WeakMap's ~200ns. +2. **Alternative: Use a global counter on the node.** The `setupDelegation` function already walks the tree — pre-assign IDs during tree walk. + +**Estimated Gain:** 10-20x faster per-node ID lookup. For deep trees: 2-3x overall event handling speedup. + +**Trade-off:** Adds a hidden property to DOM nodes. Non-enumerable, non-configurable. No memory leak because DOM nodes are GC'd anyway. + +--- + +### BOTTLENECK #9: _applyProps Creates Object.keys() Array [MEDIUM] +**Impact: Eliminates array allocation per prop application** + +**Location:** `mount.ts:38-78`, `patch.ts:40-49` + +**Problem:** `Object.keys(props)` creates a new array on every `_applyProps` call. For an element with 5 props, this allocates a 5-element array. During a full re-render of 1000 elements, that's 1000 array allocations. + +**Proposed Fix:** +1. **Cache keys in the VNode** — if the template is compiled, the keys are known at compile time. Store them as a pre-extracted array. +2. **For patch diffing**, iterate `newProps` using `for...in` instead of `Object.keys()`: + ```typescript + for (const key in props) { + if (!Object.prototype.hasOwnProperty.call(props, key)) continue; + // ... apply prop + } + ``` +3. **For the patch remove path** (line 42-49), iterate old keys and check against new. Already using `Object.keys()` there too. + +**Estimated Gain:** 30-50% reduction in allocation during prop application. + +--- + +### BOTTLENECK #10: patch.ts Remove Path Uses `key in newProps` [LOW] +**Impact: Minor but free** + +**Location:** `patch.ts:45` + +**Problem:** `key in newProps` performs prototype chain walk. Should use `Object.hasOwn()` or `newProps.hasOwnProperty(key)`. + +**Proposed Fix:** Replace with `newProps[key] !== undefined` or `Object.hasOwn(newProps, key)`. + +--- + +### BOTTLENECK #11: Compiler parse.ts Creates JSON.stringify/parse for Every Element [MEDIUM] +**Impact: 2x faster template compilation** + +**Location:** `parse.ts:127-138, 278-279` + +**Problem:** Every open tag token stores its data as `JSON.stringify({tag, attributes})`, and the parser does `JSON.parse(t.value)` to reconstruct it. For a template with 100 elements, that's 100 stringify+parse round-trips. + +**Proposed Fix:** Store token data as a structured object directly, not as a JSON string: +```typescript +interface OpenTagData { tag: string; attributes: Record; } +// Token stores: { type: 'open', data: { tag: 'div', attributes: {...} }, loc } +// Parser reads: const data = t.data; const node = { tag: data.tag, ... } +``` + +**Estimated Gain:** ~2x faster template compilation (compile-time only, doesn't affect runtime). + +--- + +### BOTTLENECK #12: Compiler optimize.ts Allocates New Arrays via filter/spread [LOW] +**Impact: Eliminates compile-time allocations** + +**Location:** `optimize.ts:12,21,94`, `reorder.ts:94-102` + +**Problem:** +- `_dce` uses `instrs.filter(...)` — creates new array +- `_dce` uses `{ ...ins, nested: _dce(ins.nested) }` — creates new objects per instruction +- `reorderInstructions` uses spread `[...creates, ...texts, ...]` — creates a new array + +**Proposed Fix:** Use in-place mutation: +```typescript +// Instead of filter + map: +let writeIdx = 0; +for (let i = 0; i < instrs.length; i++) { + if (_shouldKeep(instrs[i])) { + instrs[writeIdx++] = instrs[i]; + } +} +instrs.length = writeIdx; +``` + +**Estimated Gain:** ~50% reduction in compiler memory allocations. + +--- + +### BOTTLENECK #13: physics.ts Copies WASM Memory to SharedBuffer Per Frame [HIGH] +**Impact: Eliminates 4MB/frame copy for 500k particles** + +**Location:** `physics.ts:94-100` + +**Problem:** +```typescript +for (let i = 0; i < _count; i++) { + const wasmBase = i; + const wasmBaseY = _count + i; + const sharedBase = dataStart + i * FLOATS_PER; + _sharedData[sharedBase] = f32[wasmBase]; + _sharedData[sharedBase + 1] = f32[wasmBaseY]; +} +``` +For 500k particles, this is 500k individual float copies from WASM memory to SharedArrayBuffer. That's 500k × 2 = 1M float reads + 1M float writes. + +**Proposed Fix:** +1. **Write directly to shared buffer from WASM.** Make the Zig physics module write positions to a shared memory region instead of its own heap. Then the main thread reads directly — zero copy. +2. **If that's not possible:** Use `TypedArray.set()` with a subarray: + ```typescript + // SoA → interleaved copy with TypedArray bulk operations + const posX = new Float32Array(_wasmMemory.buffer, 0, _count); + const posY = new Float32Array(_wasmMemory.buffer, _count * 4, _count); + // Interleaved write in chunks of 1024 for cache locality + ``` +3. **Best: Change physics Zig to write interleaved (x,y) directly** so no SoA→AoS conversion is needed. + +**Estimated Gain:** For 500k particles: from ~2ms/frame to ~0.2ms/frame (10x). This is the single biggest win for the physics pipeline. + +--- + +### BOTTLENECK #14: physics.zig Has Branch in Inner Loop [LOW] +**Impact: ~10-15% faster physics step** + +**Location:** `physics.zig:150-186` + +**Problem:** `physics_step()` has a branch `if (is_forming)` inside the inner loop. The branch predictor handles this well (always taken or always not), but it prevents the compiler from fully unrolling/scheduling the two code paths. + +**Proposed Fix:** Split into two functions: +```zig +export fn physics_step_form() void { /* form path */ } +export fn physics_step_chaos() void { /* chaos path */ } +``` +JS calls the appropriate one based on mode. This eliminates the branch from the hot loop entirely and allows Zig's optimizer to fully vectorize each path independently. + +**Estimated Gain:** ~10-15% faster physics step (0.5-1ms saved per 500k particles). + +--- + +### BOTTLENECK #15: DOM Reorder Does Per-Node insertBefore [MEDIUM] +**Impact: 2-5x faster list reordering** + +**Location:** `reconcile.ts:97-119` + +**Problem:** For each item in the insert order, `parent.insertBefore(node, insertBefore)` is called individually. Even with the `parentNode !== parent || node.nextSibling !== insertBefore` optimization, this still triggers individual DOM mutations. The browser can't batch these into a single layout pass. + +**Proposed Fix:** +1. **Use Range API for batch move:** + ```typescript + const range = document.createRange(); + range.setStartBefore(anchor); + // Collect all nodes to move + // Single range.deleteContents() + range.insertNode(frag) + ``` +2. **Use `Array.move()` pattern** if available. +3. **For large lists, use innerHTML re-serialization** — faster than individual moves for >1000 items. + +**Estimated Gain:** For 1000-item list reorder: from ~5ms to ~1-2ms. + +--- + +### BOTTLENECK #16: Text Cache cloneNode is Unnecessary for Static Content [LOW] +**Impact: Minor allocation savings** + +**Location:** `vnode.ts:52,59,66` + +**Problem:** `createTextVNode` clones cached text nodes via `cloneNode(true)`. For static text, the same node could be reused by reference (text nodes are mutable — just update `textContent`). + +**Proposed Fix:** For text cache hits, return the cached node directly if it's not in the DOM. Or use a reference-counted approach. + +--- + +### BOTTLENECK #17: SSR _escapeHtml Uses Map Lookup Per Character [LOW] +**Impact: 2-3x faster SSR escaping** + +**Location:** `ssr.ts:18-38` + +**Problem:** `_escapeChars.get(code)` performs a Map lookup per character in the input. For a 10KB HTML string, that's 10K Map lookups. + +**Proposed Fix:** Use a 128-element array (lookup table) indexed by char code: +```typescript +const _escapeTable: (string | null)[] = new Array(128); +_escapeTable[38] = '&'; +_escapeTable[60] = '<'; +// etc. +// Then: const escaped = _escapeTable[code]; — O(1), no hashing +``` + +**Estimated Gain:** ~3x faster SSR string escaping for HTML-heavy content. + +--- + +### BOTTLENECK #18: router._splitSegments Allocates Array Per Call [LOW] +**Impact: Zero-allocation router matching** + +**Location:** `router.ts:63-78` + +**Problem:** `_splitSegments` allocates a `segments[]` array and pushes substrings on every navigation. + +**Proposed Fix:** Use an iterator that yields segment boundaries without allocating: +```typescript +function* _segmentIter(path: string) { + let start = -1; + for (let i = 0; i <= path.length; i++) { + if (i === path.length || path.charCodeAt(i) === 47) { + if (start >= 0) { + yield { start, end: i }; + start = -1; + } + } else { + if (start < 0) start = i; + } + } +} +// Trie matching uses string.substring() directly from the iterator +``` + +**Estimated Gain:** Zero allocations on navigation. 2-3x faster route matching. + +--- + +### BOTTLENECK #19: subs-flat.ts Calls getCore() Per Function [LOW] +**Impact: Minor but free** + +**Location:** `subs-flat.ts:11-44` + +**Problem:** Every `subsInit`, `subsAdd`, `subsRemove`, etc. calls `getCore()` independently. In `subsForEach`, it calls `getCore()` once for length, then once per iteration. + +**Proposed Fix:** Cache core reference at module level, or inline the WASM calls. + +--- + +### BOTTLENECK #20: ultra-scene-editor.ts Creates 1M+ Signals [HIGH] +**Impact: 50x fewer signal allocations for scene editor** + +**Location:** `ultra-scene-editor.ts:76-113` + +**Problem:** `createObjectSignals()` creates **18 signals per object** (posX/Y/Z, rotX/Y/Z, scaleX/Y/Z, colorR/G/B/A, visible, selected, velX/Y/Z, mass, radius, fixed). For 500k objects: **9 million signals**. Each signal allocation = WASM call + arena alloc + typed array init. + +**Proposed Fix:** +1. **Don't use individual signals for bulk data.** Use the SharedArrayBuffer directly for transforms/colors. The Zig physics module already writes to shared memory — the scene editor should read from it directly. +2. **Use a single "dirty" signal per object** instead of per-property signals. When any property changes, mark the object dirty. +3. **For batch updates** (e.g., "set all selected objects' position"), write directly to the SharedArrayBuffer — zero signals needed. + +**Estimated Gain:** From 9M signal allocations to ~500k "dirty" signals. 95% reduction in allocation time. 10x faster scene initialization. + +--- + +### BOTTLENECK #21: dom-pool.ts Not Wired Into Core [MEDIUM] +**Impact: Eliminates createElement calls for pooled elements** + +**Location:** `dom-pool.ts` — fully implemented but `batchCreate` and `batchSetAttrs` are never called by mount/patch. + +**Problem:** The DomPool class pre-allocates DOM elements and recycles them. `batchCreate` creates elements in a DocumentFragment for zero-reflow batch append. But **neither is used by the core mount/patch/reconcile pipeline**. + +**Proposed Fix:** Wire DomPool into `mount.ts`: +```typescript +// In mount(): +const el = domPool.acquire(); // O(1), zero allocation +// ... set props +``` +And into `reconcile.ts` for CMD_CREATE operations. + +**Estimated Gain:** Eliminates `document.createElement()` calls in steady state. For 1000-element re-renders: saves ~1000 createElement + associated GC pressure. + +--- + +### BOTTLENECK #22: WASM Memory is Fixed at 4MB [HIGH] +**Impact: Enables larger datasets without crash** + +**Location:** `wasm-glue.ts:106,178` + +**Problem:** `new WebAssembly.Memory({ initial: 1024, maximum: 1024 })` = 1024 pages × 64KB = 64MB. But `RECONCILE_BASE` is hardcoded at `DYNAMIC_START + 262144`. The heap is `[1048576]u32` = 4MB in Zig. If signal count > ~4096, or string data exceeds the dynamic region, the WASM module silently corrupts memory. + +**Proposed Fix:** +1. Make memory growable: `maximum: 256` (16MB) or use `WebAssembly.Memory({ initial: 256, maximum: 1024 })`. +2. Add bounds checks in Zig for all writes. +3. Make `RECONCILE_BASE` computed from `heap_base()` rather than hardcoded. + +**Estimated Gain:** Prevents silent memory corruption. Enables scaling to >100k signals. + +--- + +### BOTTLENECK #23: Effect Re-Run Clears All Deps Even If Unchanged [MEDIUM] +**Impact: 2-3x fewer subscriber operations for stable effects** + +**Location:** `dominator_core.zig:326-339, 476` + +**Problem:** `effect_begin(id)` calls `clearEffectDeps(id)`, which iterates ALL dependencies and calls `subs_remove()` on each. Then during re-execution, the effect re-subscribes to the same signals. For a stable effect that reads 10 signals, this is 10 subs_remove + 10 subs_add = 20 WASM operations. + +**Proposed Fix:** +1. **Generation-based deps:** Instead of clearing deps, increment a generation counter. During re-execution, record which signals were touched with the current generation. After execution, compare with previous generation — only remove subscriptions for signals NOT touched. +2. **Snapshot-swap:** Take a snapshot of current deps, clear them, re-run, compare new deps with snapshot, only add/remove the diff. + +**Estimated Gain:** For stable effects (reading same signals): from 20 WASM ops to ~2-3 (just the diff). For large dependency graphs: 5-10x fewer operations. + +--- + +### BOTTLENECK #24: Hash Table for Reconciliation Uses Linear Probing [LOW] +**Impact: Better worst-case for hash collisions** + +**Location:** `dominator_core.zig:530-565` + +**Problem:** The hash table uses linear probing with no tombstone handling. If keys hash to the same bucket, probe sequence degrades. For pathological key distributions (e.g., all keys hash to same bucket), performance degrades to O(n²). + +**Proposed Fix:** Use Robin Hood hashing or switch to quadratic probing. For the WASM context, Robin Hood is ideal because it improves worst-case lookup from O(n) to O(log n). + +**Estimated Gain:** Negligible for random keys, significant for pathological cases. + +--- + +### BOTTLENECK #25: No SIMD in Physics Inner Loop [HIGH] +**Impact: 2-4x faster physics for 500k particles** + +**Location:** `physics.zig:143-192` + +**Problem:** The physics step processes one particle at a time. WASM SIMD (128-bit vectors) can process 4x f32 operations simultaneously. The loop body is simple enough for auto-vectorization: +``` +x += vx; y += vy; vx *= damping; vy *= damping; +``` +But the scattered memory access pattern (SoA with stride `_count`) defeats auto-vectorization. + +**Proposed Fix:** +1. **Process 4 particles at a time:** + ```zig + var i: u32 = 0; + while (i + 4 <= _count) : (i += 4) { + const x_vec = [4]f32{ getPosX(i), getPosX(i+1), getPosX(i+2), getPosX(i+3) }; + const vx_vec = [4]f32{ getVelX(i), getVelX(i+1), getVelX(i+2), getVelX(i+3) }; + // ... SIMD operations + } + ``` +2. **Use `@import("std").simd`** for explicit SIMD intrinsics. +3. **Build with `-OReleaseFast -target wasm32-simd`** to enable WASM SIMD in the build. + +**Estimated Gain:** 2-4x faster physics step. For 500k particles: from ~4ms to ~1-2ms. + +--- + +### BOTTLENECK #26: css-batch.ts applyFullFromBuffer Creates Array Per Frame [LOW] +**Impact: Eliminates per-frame allocation** + +**Location:** `css-batch.ts:103-107` + +**Problem:** `applyFullFromBuffer` allocates `new Array(101)` for the alpha LUT on every call. + +**Proposed Fix:** Hoist to module scope: +```typescript +const _alphaStrs: string[] = new Array(101); +for (let i = 0; i <= 100; i++) { + _alphaStrs[i] = (i / 100).toFixed(2); +} +``` + +**Estimated Gain:** Eliminates 101-element array allocation per frame. + +--- + +### BOTTLENECK #27: codegen.ts Uses String Concatenation in Hot Loop [LOW] +**Impact: 2x faster code generation** + +**Location:** `codegen.ts:103-126` + +**Problem:** Building the output string via `parts.push()` then `parts.join('')` is actually fine (push is amortized O(1)). But the individual `parts.push(`${indent}const ${target} = document.createElement(...)`)` calls create template literals per instruction. For 1000 instructions, that's 1000 template literal allocations. + +**Proposed Fix:** Pre-compute common prefixes and use string concatenation: +```typescript +parts.push(indent); parts.push('const '); parts.push(target); +parts.push(' = document.createElement("'); parts.push(tag); parts.push('");\n'); +``` +Or better: write to a single growing string with a position counter (avoids array entirely). + +--- + +### BOTTLENECK #28: reconcile Key/Node ID Maps Grow Unboundedly [MEDIUM] +**Impact: Prevents memory leak in long-running apps** + +**Location:** `reconcile.ts:131-157` + +**Problem:** `_nodeToId` (WeakMap) and `_keyToId` (Map) and `_idToNode` (Map) grow forever. Keys that are removed from the list still have entries in `_keyToId`. Nodes that are removed from the DOM still have entries in `_idToNode`. + +**Proposed Fix:** Add periodic cleanup: +```typescript +// After reconcile, remove entries for nodes not in the current tree +for (const [id, node] of _idToNode) { + if (!node.parentNode) _idToNode.delete(id); +} +``` +Or use WeakRef + FinalizationRegistry for automatic cleanup. + +--- + +### BOTTLENECK #29: signal.subscribe() Unsubscribe Doesn't Actually Remove [HIGH] +**Impact: Prevents memory leak and stale callback execution** + +**Location:** `signal.ts:229-236` + +**Problem:** The unsubscribe function does: +```typescript +return () => { + const curLen = _manualSubLens[id]; + const curOffset = _manualSubOffsets[id]; + const idx = curLen - 1; + _manualSubFns[curOffset + idx] = undefined as any; + _manualSubLens[id] = curLen - 1; +}; +``` +This always removes the **last** subscriber, not the one that called unsubscribe. If signal A has subscribers [fn1, fn2, fn3] and fn2 unsubscribes, it removes fn3 instead. + +**Proposed Fix:** Track the subscriber's index in the closure: +```typescript +s.subscribe = (fn: Subscriber) => { + // ... allocate slot + const subIdx = _manualSubDataLen; // or wherever it was placed + return () => { + // Find and remove this specific subscriber + const offset = _manualSubOffsets[id]; + const len = _manualSubLens[id]; + for (let i = 0; i < len; i++) { + if (_manualSubFns[offset + i] === fn) { + // Swap with last + _manualSubFns[offset + i] = _manualSubFns[offset + len - 1]; + _manualSubLens[id] = len - 1; + break; + } + } + }; +}; +``` + +**Estimated Gain:** Correctness fix. Prevents memory leak and stale callback execution. + +--- + +### BOTTLENECK #30: flushSync Doesn't Respect Dedup [MEDIUM] +**Impact: Prevents double effect execution** + +**Location:** `signal.ts:305-314` + +**Problem:** `flushSync()` calls `_runEffect` for each dirty effect ID without dedup. If the same effect is dirty from multiple signals, it runs multiple times. + +**Proposed Fix:** Add dedup bitmap check like `batch()` does. + +--- + +### BOTTLENECK #31: No Prefetch for Sequential Signal Access [LOW] +**Impact: 10-20% faster signal reads in effects** + +**Location:** `signal.ts:150-156` + +**Problem:** When an effect reads signals sequentially (e.g., `const x = signal1(); const y = signal2();`), each `arenaReadRaw` triggers a separate WASM call. The CPU can't prefetch across WASM boundaries. + +**Proposed Fix:** For compiled templates, batch-read signals: +```typescript +// Instead of: +const x = signal1.get(); +const y = signal2.get(); +const z = signal3.get(); + +// Do: +const [x, y, z] = batchRead([signal1._id, signal2._id, signal3._id]); +// Single WASM call that reads 3 values +``` + +--- + +### BOTTLENECK #32: No Memory Barrier Between Worker and Main Thread [MEDIUM] +**Impact: Prevents stale reads on weakly-ordered CPUs** + +**Location:** `worker/physics.ts:82-86` + +**Problem:** `Atomics.load` is used for reading shared header, but the particle data in SharedArrayBuffer is read without any memory fence. On ARM (mobile) or weakly-ordered x86, the main thread might read stale position data. + +**Proposed Fix:** Add `Atomics.load` for the frame counter before reading particle data: +```typescript +// Read frame counter to ensure data is fresh +const frame = Atomics.load(sharedHeader, 2); +// Now read particle data — CPU will see the latest write +``` + +--- + +### BOTTLENECK #33: DomPool.release() Sets dataset.r and dataset.c to undefined [LOW] +**Impact: Prevents DOM attribute leak** + +**Location:** `dom-pool.ts:58-61` + +**Problem:** Setting `el.dataset.r = undefined` actually sets the attribute to `"undefined"` (string). Should use `delete el.dataset.r`. + +**Proposed Fix:** Use `delete` operator. + +--- + +### BOTTLENECK #34: No Arena Compaction [MEDIUM] +**Impact: Prevents arena overflow for long-running apps** + +**Location:** `dominator_core.zig:205-213` + +**Problem:** `arena_reset()` zeros the entire arena and resets all counters. But there's no partial compaction — if 50% of signals are disposed, the arena still holds their data. + +**Proposed Fix:** Implement a generational arena with sweep: +```zig +// Mark-and-sweep for disposed effects +// Compact live signal values to the beginning of the arena +// Update all subscriber offset/length arrays +``` + +--- + +### BOTTLENECK #35: No Batch Coalescing for Nested Batches [LOW] +**Impact: Prevents redundant flushes** + +**Location:** `signal.ts:277-303` + +**Problem:** Nested `batch()` calls correctly increment/decrement `_batch_depth` in Zig. But the JS-side `batch()` function calls `core.batch_end()` and checks the return. For nested batches, the inner `batch_end()` returns 0 (correct), but the outer `batch_end()` returns the effect list (also correct). This is fine — no bug here. However, `computed()` wraps its effect in `batch()`: +```typescript +effect(() => { batch(() => { s.set(fn()); }); }); +``` +This means every computed update creates + ends a batch inside an effect. The extra batch_begin/batch_end calls are unnecessary overhead. + +**Proposed Fix:** Use `signal_mark_dirty` directly inside computed effects, bypassing the batch layer. + +--- + +## 4.

WHAT'S ALREADY EXCELLENT + +1. **Zig WASM for core reactivity** — Arena allocation, dirty tracking, and reconciliation in WASM is the right call. WASM JIT can optimize these hot loops better than V8 for pure computation. +2. **Flat event delegation** — Single root listener with charCode dispatch avoids per-element listener overhead. +3. **SharedArrayBuffer worker bridge** — Zero-copy main↔worker communication is textbook HPC. +4. **WebGPU instanced rendering** — Correct approach for 500k+ objects. +5. **Compiler pipeline** — SSA form, DCE, constant folding, effect hoisting — this is a real compiler, not a toy. +6. **O(n+m) reconciliation** — Hash map in WASM for keyed list diffing is optimal. +7. **Pre-allocated dirty buffers** — Avoiding allocation in the dirty tracking hot path is correct. +8. **Batch dedup bitmap** — O(1) dedup check is the right algorithm. +9. **SoA physics layout** — Structure of Arrays in Zig is exactly right for SIMD. +10. **Pool pattern** — Ring buffer with bitmask wrap is lock-free and cache-friendly. + +--- + +*This report represents analysis of every line in `packages/core/src/` — 43 files, ~8,100 lines.

It uses `Float64Array`, `Uint8Array`, and parallel tag arrays to store numeric, string, boolean, and object values without boxing, reducing garbage collection overhead and improving performance for reactive data. +* **`batch.ts`**: A utility file that re-exports the `batch` and `flushSync` functions from `./signal.ts`. Its primary purpose is to provide a convenient way to import and use the batching mechanism for reactive updates. +* **`css-batch.ts`**: Contains optimized utilities for batched application of styles to the DOM. It leverages techniques like string concatenation for `cssText` assignments, CSS custom properties (`--x`, `--y`) for GPU-composited transforms, and `SharedArrayBuffer` for bulk updates, aiming for maximum DOM throughput. +* **`dom-pool.ts`**: Provides a `DomPool` class for pre-allocating and recycling DOM elements. This mechanism reduces the overhead of `document.createElement()` calls and minimizes garbage collection, especially in scenarios with frequent element creation/destruction (e.g., particle systems). It also includes functions for batch creating elements into a `DocumentFragment` and batch setting attributes. +* **`events.ts`**: Implements a delegated evstem. It attaches a single event listener to the root element for a predefined set of event types. Events then bubble up, and handlers are dispatched efficiently based on `nodeId`s, optimizing event handling and reducing memory footprint by avoiding numerous individual event listeners. +* **`index.ts`**: The main public entry point for the `@dominator/core` package. It exports various modules and interfaces, including the reactive engine (`signal`, `effect`, `computed`), DOM manipulation utilities (`mount`, `patch`, `DomPool`), routing (`createRouter`), server-side rendering (`renderToString`), and compiler-related utilities. It also defines `DominatorApp` and `createApp` for initializing applications. +* **`mount.ts`**: Contains the core `mount` function responsible for the initial rendering of a Virtual Node (VNode) tree into actual DOM elements. It recursively processes VNodes, creates corresponding DOM elements, applies properties (attributes and event listeners), and appends children, optimizing for initial DOM creation. +* **`patch.ts`**: Implements the `patch` algorithm for efficient DOM updates. It compares an `oldVNode` tree with a `newVNode` tree and performs only the necessary DOM mutations (creating, updating, moving, or deleting elements and text nodes) to synchronize the DOM with the new VNode tree. Includes `patchChildren` for list reconciliation. +* **`pool.ts`**: Provides a generic `Pool` class for object pooling, a common optimization technique to reduce memory allocations and garbage collection pressure. It specifically exports `vnodePool`, an instance of `Pool` tailored for recycling `VNode` objects used in the virtual DOM. +* **`reconcile.ts`**: Implements a reconciliation algorithm for efficiently updating lists of DOM nodes (e.g., when rendering dynamic lists of items). It uses a keyed approach to track existing elements, minimizing DOM operations by reusing and reordering nodes rather than recreating them. +* **`router.ts`**: Implements a client-side routing solution. It uses a `signal` to track the current path and a trie data structure for efficient route matching. The `createRouter` function sets up the router to dynamically render components based on the current URL path and provides a `navigate` function for programmatic navigation. +* **`signal.ts`**: The heart of the Dominator reactive engine. It defines and implements `signal` (observable state), `effect` (side-effecting reactions), `computed` (derived state), `batch` (grouping updates), and `flushSync` (forcing synchronous updates). It uses a data-oriented design with flat typed arrays and an arena allocator for highly performant reactivity. +* **`ssr.ts`**: Provides Server-Side Rendering (SSR) functionality. The `renderToString` function takes a list of `SSRInstruction`s (representing DOM operations) and converts them into a static HTML string. It includes basic HTML escaping to prevent XSS vulnerabilities. +* **`subs-flat.ts`**: Implements a highly optimized, flat, and bit-packed storage mechanism for signal subscriber lists (effect IDs). It uses `Uint32Array` and `Uint8Array` to store subscriber data in contiguous memory blocks, avoiding small object allocations and improving cache locality for the reactive graph. +* **`vnode.ts`**: Defines the `VNode` (Virtual Node) interface, which represents a lightweight description of a DOM element or component. It provides `createVNode` for creating element VNodes and `createTextVNode` for text nodes, including a text node cache to optimize for frequently used static text. + +## Compiler Subdirectory (`packages/core/src/compiler/`) + +* **`codegen.ts`**: The code generation phase of the Dominator compiler. It takes a list of Static Single Assignment (SSA) instructions and transforms them into executable JavaScript code. This includes generating DOM creation, attribute setting, event listener attachment, text updates, and control flow logic (`each`, `if`) using the reactive `effect` primitive. It also includes `validateExpression` to prevent unsafe code. +* **`hoist.ts`**: A compiler optimization pass focused on "effect hoisting." It identifies and merges adjacent dynamic attribute or expression instructions that target the same DOM element. By grouping these into a single `effect()` block, it reduces the number of effect function calls and improves runtime performance. +* **`optimize.ts`**: Contains a suite of compiler optimization passes. These include: + * **Dead Code Elimination (`_dce`)**: Removes redundant or unnecessary instructions (e.g., empty text nodes, attributes with undefined values). + * **Static Folding (`_foldStatic`)**: Evaluates constant expressions at compile time, replacing dynamic expressions with their static results (e.g., arithmetic operations, string literals). + * **Static Text Merging (`_mergeStaticText`)**: Combines consecutive static text nodes into a single text node, reducing the number of DOM nodes. +* **`parse.ts`**: Implements the lexer (tokenizer) and parser for the Dominator templating language. It tokenizes the input source into a stream of tokens (tags, text, expressions, block delimiters) and then parses these tokens to construct an Abstract Syntax Tree (AST), representing the hierarchical structure of the template. +* **`reorder.ts`**: A compiler pass that reorders the generated SSA instructions. It groups instructions by type (create, text, static attributes, events, append, dynamic expressions, blocks) to improve cache locality during DOM operations and optimize rendering performance. +* **`ssa.ts`**: Converts the Abstract Syntax Tree (AST) into Static Single Assignment (SSA) form. This pass flattens the hierarchical AST into a linear list of `Instruction` objects, where each instruction represents a distinct operation on the DOM or the reactive system. Each DOM element or text node is assigned a unique identifier (e.g., `v0`, `v1`). +* **`vite-plugin.ts`**: Provides a Vite plugin (`dominatorPlugin`) to integrate the Dominator compiler seamlessly into a Vite build pipeline. It hooks into Vite's `transform` phase for files ending with `.dnr`, applying the full compilation pipeline: parsing, SSA conversion, optimization, reordering, hoisting, and code generation. + +## Worker Subdirectory (`packages/core/src/worker/`) + +* **`physics.ts`**: Implements the core 2D particle physics simulation logic. It is designed to run entirely within a Web Worker. It uses a Structure of Arrays (SoA) memory layout with `Float32Array` for efficient, SIMD-friendly access to particle positions, velocities, and targets. It handles particle movement, mouse repulsion, target snapping, and an explosion effect, communicating with the main thread via a `SharedArrayBuffer` for zero-copy data transfer. +* **`scheduler.ts`**: Defines the shared memory layout and the communication protocol between the main thread and the Web Worker using `SharedArrayBuffer` and `Atomics`. It specifies the structure of the shared buffer, including command flags, particle count, frame numbers, mouse coordinates, and mode settings. It provides helper functions (`setHeaderCommand`, `waitCommand`, `signalReady`, etc.) for atomic operations, enabling efficient inter-thread communication. +* **`worker-entry.ts`**: The main entry point for the Web Worker. It receives an `init` message from the main thread containing a `SharedArrayBuffer` and particle count. It then initializes the `physics` engine, sets up the shared memory views, signals its readiness to the main thread, and enters a continuous 60fps physics simulation loop. It also handles messages for updating particle targets or triggering effects like explosions. diff --git a/dominator_core.o b/dominator_core.o new file mode 100644 index 0000000..116ecbf Binary files
