Pattern Nexus Evolution Lab
Live survival simulations with saved runs, presets, and replay pages.
Evolution simulation lab

Build survival simulations where agents have to search, miss, adapt, reproduce, and sometimes collapse.

Safe zones move, populations begin outside safety, and each generation has to solve the map again instead of spawning already protected.

Browser mode shows the live hunt. Server mode is for heavier saved runs, presets, and shareable result pages.

Run notes

Browser mode

Best for watching live behavior and tuning movement pressure in real time.

Server mode

Best for heavier saved runs, replay pages, exports, and comparing different parameter sets.

Preset save

Use the save preset button after naming the run. The preset stores the current control panel settings only.

Live view

Safe zones drift slower, generations run longer, and agents have to search their way back into safety.

Publishing notes

Cleaner public labels

Preset cards and run summaries now use readable labels instead of raw snake_case values.

Admin hidden by default

The admin link only appears when an admin session is active, so the public page stays clean.

Canvas rendering tightened

The simulation view now centers the world correctly, uses safe padding, and resizes more reliably.
