WIRED

WIRED

Pixels implements the official WIRED behavior families using the Polaris-compatible layout codes transported by Nitro's existing action, trigger, and condition definition packets.

The immutable room generation contains 130 canonical behaviors:

• 22 triggers
• 43 effects
• 33 conditions
• 20 selectors
• 4 variable definitions
• 7 stack add-ons
• 1 highscore family

Selectors resolve only from warmed live-room state. Empty selector results are authoritative and never fall back to an effect's stored targets. Remote selectors are bounded to four levels, target results are deduplicated and stable, and each target family is limited by PIXELS_WIRED_MAX_SELECTION_RESOLUTION.

Variable assignments use four scopes: furniture, user, room, and reference. Rows are loaded once when the room runtime starts, read from the warmed cache, written durably through room_wired_variables, and released from memory when the room closes. Room deletion removes assignments through the database foreign key.

Signals are intra-room, derived inside one serialized execution trace, and discarded after the trace. PIXELS_WIRED_MAX_SIGNALS_PER_TICK prevents signal cycles from consuming an unbounded event budget.

Performance checks

Run the hot-path benchmarks with allocation reporting:

go test ./internal/realm/room/world/wired/runtime/tests \
  -run '^$' -bench 'Benchmark(NoCandidateDispatch|IndexedDispatch)$' -benchmem
go test ./internal/realm/room/world/wired/selection \
  -run '^$' -bench BenchmarkResolveArea -benchmem
go test ./internal/realm/room/world/wired/variable \
  -run '^$' -bench BenchmarkWarmedGet -benchmem

The no-candidate event path and warmed variable lookup are required to remain allocation free.
