- Home/Counter/Todos/About with hash navigation
- State persists across route changes
- Uses existing router infrastructure (no compiler changes)

- 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

Codegen: BinOp::Div now emits Math.trunc(l / r)
- Clock displays 0:1:30 instead of 0.016:1.5:30
- Affects both emit_expr and predicate_to_js
Lexer: removed duplicate 'in' keyword mapping
- InKw at line 312 is canonical, removed old In at line 338
Examples: added project-tracker.ds (each loops + cards)
Add compose-metrics.ds (Layer 1): receives counter+clock+stats,
derives uptime/events/status, re-streams on /peer/metrics. This app
is BOTH a receiver and a source.
Add compose-master.ds (Layer 2): receives chained metrics from
Layer 1 + mood direct from Layer 0. Demonstrates multi-layer
signal composition with independent stream mixing.
Verified: Uptime: 51s, Total Events: 9 flowing through the full
three-layer chain to the master dashboard.
The 'default' relay channel accumulated stale Source connections from
previous sessions, causing frame delivery issues to Receivers on
/stream/default. Moving counter to an explicit /peer/counter channel
(matching clock, stats, mood pattern) fixes the composition dashboard.
All 4 streams now show live data: Count: 3, Doubled: 6.
Add 3 new streaming apps with explicit output declarations:
- streaming-clock.ds: output hours, minutes, seconds (tick private)
- streaming-stats.ds: output total, average, max (sum private)
- streaming-mood.ds: output mood, energy, color (clicks private)
Add compose-dashboard.ds that receives all 4 streams via unique
relay channels (/stream/default, /stream/clock, /stream/stats,
/stream/mood) into a single dashboard view.
Each app demonstrates selective signal registration — only declared
outputs are streamed, internal state remains private.
Add 'output: field1, field2' syntax to stream declarations to control
which signals are exposed over the relay. Only listed signals are
registered in _signalRegistry (and thus streamed). Omitting output
streams all signals (backwards-compatible).
Also strips internal sync metadata (_pid, _v) from receiver state
so composition consumers only see clean signal values.
Parser: parse comma-separated idents after 'output:' key
AST: Vec<String> output field on StreamDecl
Codegen: conditional _registerSignal, delete _pid/_v on receive
Example: stream counter on 'ws://...' { mode: signal, output: count, doubled }
- Register derived signals in _signalRegistry so _streamSync includes them
- Auto-sync all signals (source + derived) after flush() recomputes effects
- Fix Object.assign identity check: create new object so signal setter detects changes
- Change _connectStream receiver path from /signal/main to /stream/default
- Initialize stream state with {} instead of null to prevent crashes
- Emit StreamFrom bindings directly without double-wrapping in signal()
Verified: static build shows Count: 9, Doubled: 18 on composition page.
HMR interference with WebSocket connections is a separate issue.
- _signalVersions: monotonic counter per signal, incremented on each local mutation
- Diffs include _v: {name: version} for version comparison
- _applyRemoteDiff only applies if remote version >= local version
- Prevents stale overwrites when both devices edit simultaneously
- onopen snapshot includes version map for late-joiner consistency
- bind: input handler now emits _streamDiff so typed text syncs
- Peers broadcast full state snapshot on WS open (late joiners sync)
- Removed dead _handleRemoteInput 0x31 case (old source/receiver model)
- Preserved scroll (0x50), pointer, and key handlers
- Added /peer/{name} route to relay: all clients are equal peers
- handle_peer: binary broadcast to all other peers, catchup for late joiners
- Simplified runtime: single /peer/ WS replaces dual source+receiver
- _peerId: random 8-char ID prevents self-echo from broadcast
- _pid in each diff JSON, filtered in _applyRemoteDiff
- Fix URL routing: /source/default and /stream/default paths
- _streamDiff sends via both source WS and receiver WS (INPUT flag)
- Source rebroadcasts 0x31 diffs from receivers to all other receivers
- Echo loop guard prevents infinite rebroadcast
Array access: Expr::Index in AST, [expr] postfix parsing, codegen for
reads (grid.value[i.value]) and writes (event handler assignments with
root signal extraction for stream diff broadcasting).
Timer: 'every N -> expr' declaration. Every keyword in lexer. EveryDecl
in AST. parse_every_decl in parser. setInterval codegen with DS.flush.
String interpolation: already committed separately.
Type checker: handles Expr::Index (infers array element type).
