feat: *= /= operators + 6 new array methods
...
New assignment operators (full pipeline: lexer → parser → analyzer → codegen):
- *= (MulAssign): count *= 2
- /= (DivAssign): count /= 2
New array methods in event handler (all flush signal + stream diff):
- .clear() → items = []
- .insert(i, v) → splice at index
- .sort() → immutable sort
- .reverse() → immutable reverse
- .filter(fn) → filter in place
- .map(fn) → map in place
New example: language-features.ds (65KB)
- Tests all assignment ops (+=, -=, *=, /=)
- Tests array methods (push, pop, sort, reverse, clear)
- Tests match expressions
- Tests comparison operators
- Tests derived signals (let doubled = count * 2)
- Browser-verified: zero console errors
All 11 examples pass.

feat: when/else conditional branching
...
- AST: When(cond, body) -> When(cond, body, Option<else_body>)
- Parser: optional 'else -> expr' after when body
- Codegen: reactive DOM swap with anchor comments
- Signal graph + type checker updated for 3-arg When
- Component prop signal wrapping: .value compatible accessors
- Added examples/when-else-demo.ds

feat(compiler): complete bitstream integration — all 9 changes
...
- AST: StreamDecl, StreamMode, Declaration::Stream, StreamFrom struct variant
- Lexer: Pixel, Delta, Signals keywords
- Parser: parse_stream_decl with mode block, fixed TokenKind::On match
- Signal graph: streamable flag, SignalManifest, Declaration::Stream detection
- Checker: StreamFrom { source, .. } pattern
- Codegen: DS._initStream(), DS._connectStream(), DS._streamDiff() hooks
- Runtime JS: full streaming layer with binary protocol encoding
- Layout: to_bytes/from_bytes on LayoutRect
82 tests pass (5 new: 3 parser stream + 2 analyzer streamable)

feat(compiler): full bitstream integration across 7 pipeline stages
...
AST: StreamDecl, StreamMode, Expr::StreamFrom { source, mode }
Lexer: Pixel, Delta, Signals keywords
Parser: parse_stream_decl() with mode parsing, StreamFrom expression
Signal Graph: streamable flag on SignalNode, auto-detect stream decls
Type Checker: StreamFrom returns Type::Stream
Codegen: emit_stream_init phase, StreamFrom → DS.streamConnect(),
streaming runtime JS (WebSocket relay, binary protocol, signal frames,
remote input handler, auto-reconnect)
CLI: 'dreamstack stream' command — compile+serve with streaming enabled,
auto-inject stream declaration for the first view
All 77 workspace tests pass, 0 failures.

feat: physics language integration — scene container with Rapier2D WASM
...
- Add scene container to AST, lexer, parser, analyzer, and codegen
- Add circle/rect/line as UI elements for physics body declaration
- Compile scene {} to canvas + async WASM init + Rapier2D PhysicsWorld
- Reactive gravity via DS.effect() — bodies wake on gravity change
- Mouse drag interaction with impulse-based body movement
- Compile-time hex color parsing for body colors
- Fix is_signal_ref matching numeric literals (700.value bug)
- Fix body variable uniqueness (next_node_id per body)
- Fix gravity signal detection (check AST Ident before emit_expr)
- Add physics.ds example with 5 bodies + 4 gravity control buttons
- Update DREAMSTACK.md and IMPLEMENTATION_PLAN.md with Phase 10-11
- 39 tests pass across all crates, 22KB output

feat: DreamStack compiler foundation — Phase 0/1
...
Complete compiler pipeline from .ds source to reactive browser apps:
- ds-parser: lexer (string interpolation, operators, keywords) + recursive
descent parser with operator precedence + full AST types
- ds-analyzer: signal graph extraction (source/derived classification),
topological sort for glitch-free propagation, DOM binding analysis
- ds-codegen: JavaScript emitter with embedded reactive runtime (~3KB
signal/derived/effect system) and dark-theme CSS design system
- ds-cli: build (compile to HTML+JS), dev (live server), check (analyze)
Verified working: source signals, derived signals, event handlers,
conditional rendering (when), 12 unit tests passing, 6.8KB output.
