Learn battles and research topic routes
Learn lessons can now play as battles, with lesson enemies, boss progress, campaign maps, and completion ticks.
New
- Learn lessons can now play as battles, with lesson enemies, boss progress, campaign maps, and completion ticks.
Changed
- Research moved into the blog topic model so technical notes share the same archive and topic navigation as product writing.
Fixed
- Checker worker-pool hardening made special-judge runs safer against timeouts and runaway checkers.
Why it matters
- Practice works better when progress, pressure, and replayable evidence all point at the same skill loop.
