+# Agent Instructions for Monix
+
+This file contains mandatory rules for AI agents (Copilot, Claude, Cursor, etc.) working on this repository.
+**Any violation is a CI-breaking mistake!**
+
+---
+
+## Code rules
+
+- Never workaround the compiler, make an effort to solve errors in an idiomatic way:
+  - Avoid `asInstanceOf` downcasting, unless there's no other way (e.g., untagged union types in Scala 3).
+  - `@nowarn` annotations, or other ways for supressing warnings/errors, are not permitted without the user's consent.
+    - We fix warnings, we don't ignore them.
+- Use package imports, instead of fully qualified names.
+- Make an effort to write idiomatic, yet performant Scala code.

+## Version 3.5.0 (Mar 31, 2026)
+
+This release updates Monix 3.x support baselines for modern JVM and Scala toolchains.
+
+Breaking changes:
+
+- JDK `17` is now the minimum supported runtime and build target.
+- JDK `21` is now part of the validated support matrix.
+- Scala `2.12` support is dropped.
+- Scala `3` is upgraded to `3.8.2`.
+- Legacy `sun.misc.Unsafe`-based internals were removed in favor of JDK `VarHandle`-based implementations.
+
+This release was made possible by the work and feedback of:
+
+- Alexandru Nedelcu (@alexandru)

+/**
+  * 
+  * @define atomicGetDesc Get the current value persisted by this atomic
+  *  reference. 
+  * 
+  *  This is a "volatile read", with all visibility guarantees that come
+  *  from that.
+  * 
+  * @define atomicSetDesc Stores the given value in the atomic reference.
+  * 
+  *  This is a "volatile write", with all visibility guarantees that come
+  *  with it. For garbage-collecting purposes, but without the strong
+  *  visibility guarantees, you might want to use [[lazySet]].
+  * 
+  * @define atomicGetAndSetDesc Sets the given value and returns
+  *  the value visible just prior to the update.
+  * 
+  *  This is an atomic operation that's equivalent to:
+  *  {{{
+  *   import monix.execution.atomic._
+  * 
+   *   def getAndSet[A](ref: Atomic[A], update: A): A = {
+   *    val current = ref.get()
+   *    if (!ref.compareAndSet(current, update))
+   *      getAndSet(ref, update) // update failed, repeat!
+   *    else
+   *      current
+   *   }
+   *
+   *   val ref = Atomic(0)
+   *   val _ = getAndSet(ref, 1)
+   *  }}}
+  * 
+  *  NOTE — on top of the JVM this operation is a platform intrinsic,
+  *  meaning that it's more efficient than a `compareAndSet`-driven loop.
+  *  Therefore it isn't just a shortcut. If you can describe your logic
+  *  in terms of `getAndSet`, instead of `compareAndSet`, then you should,
+  *  but you'll also find this to be more challenging 😉
+  * 
+  * @define atomicGetAndSetParam the value that's going to be stored in 
+  *  the atomic reference once the transaction succeeds.
+  * 
+  * @define atomicGetAndSetReturn the old value that was visible in the
+  *  atomic reference, prior to the succeeding update.
+  * 
+  * @define atomicLazySetDesc Eventually sets to the given value.
+  * 
+  *  Equivalent with [[set]], but on top of the JVM this operation isn't a
+  *  volatile write, and thus has more relaxed visibility guarantees. For
+  *  nullifying values, in order to allow garbage collection, this method is
+  *  more efficient and should be prefered. But only if you know what you're
+  *  doing, otherwise just use normal [[set]].
+  * 
+  * @define compareAndSetDesc Does a compare-and-set operation on the 
+  *  current value. For more info, checkout the related
+  *  [[https://en.wikipedia.org/wiki/Compare-and-swap Compare-and-swap Wikipedia page]].
+  * 
+  *  It's an atomic, worry-free, but low-level operation. Use only if
+  *  you know what you're doing.
+  * 
+  *  Sample: {{{
+  *   import monix.execution.atomic._
+  *   import scala.collection.immutable.Queue
+  * 
+   *   class ConcurrentQueue0[A](ref: Atomic[Queue[A]]) {
+  *     def enqueue(value: A): Unit = {
+  *       val current = ref.get()
+  *       val update = current.enqueue(value)
+  *       if (!ref.compareAndSet(current, update))
+  *         enqueue(value) // transaction failed, retry!
+  *     }
+  * 
+  *     def dequeue(): Option[A] = {
+  *       val current = ref.get()
+  *       if (current.isEmpty)
+  *         None
+  *       else {
+  *         val (elem, update) = current.dequeue
+  *         if (!ref.compareAndSet(current, update))
+  *           dequeue() // transaction failed, retry!
+  *         else
+  *           Some(elem)
+   *       }
+   *     }
+   *   }
+   *
+   *   val q0 = new ConcurrentQueue0[Int](Atomic(Queue.empty[Int]))
+   *   q0.enqueue(1)
+   *   val _ = q0.dequeue()
+   *  }}}
+  * 
+  * @define atomicBestPractices BEST PRACTICES: 
+  * 
+  *  (1) state stored in this atomic reference MUST BE immutable, or 
+  *  treated as such. Storing mutable data in an atomic reference
+  *  doesn't work — unless you understand Java's memory model, and if
+  *  you have to wonder, then you don't.
+  *
+  *  (2) in `compareAndSet`-driven loops, transformation/update functions
+  *  get repeated, so those update functions MUST BE pure. If you have
+  *  to trigger side-effects, then trigger them only AFTER the update
+  *  has succeeded, not before or during the update. Failure to do so
+  *  risks repeating those side-effects more than once. Working with
+  *  an atomic reference is very unlike working with plain locks /
+  *  / mutexes / `synchronize` blocks.
+  * 
+  *  (3) the operation is not based on Java's `Object#equals` or Scala's `==`.
+  *  For primitives, value equality is going to be used, but reference
+  *  equality is used for anything else, so ensure that the `expect` reference
+  *  is the same as the one received via `get()`.
+  * 
+  * @define atomicCASExpectParam is the value you expect to be persisted when
+  *  the operation happens.
+  * 
+  * @define atomicCASUpdateParam will be the new value, should the
+  *  (reference) equality check for `expect` succeeds.
+  * 
+  * @define atomicCASReturn either `true` in case the operation succeeded or
+  *  `false` otherwise. If this returns `false`, it means that another 
+  *  concurrent transaction won the race and updated the atomic reference 
+  *  first, so you probably need to repeat the transaction.
+  *
+  * @define atomicTransformExtractDesc Updates this atomic reference in a
+  *  transaction, modeled with  a `compareAndSet`-driven loop.
+  *  This "transformation" specifies a custom extractor.
+  * 
+  *  Sample: {{{
+  *    import monix.execution.atomic._
+  *    import scala.collection.immutable.Queue
+  *         
+   *    final class ConcurrentQueue1[A](state: Atomic[Queue[A]]) {
+  *      def enqueue(value: A): Unit = 
+  *        state.transform(_.enqueue(value))
+  *  
+  *      def dequeue(): Option[A] =
+  *        state.transformAndExtract { queue =>
+  *          if (queue.isEmpty)
+  *            (None, queue)
+  *          else {
+  *            val (a, update) = queue.dequeue
+  *            (Some(a), update)
+   *          }
+   *        }
+   *    }
+   *
+   *    val q1 = new ConcurrentQueue1[Int](Atomic(Queue.empty[Int]))
+   *    q1.enqueue(1)
+   *    val _ = q1.dequeue()
+   *  }}}
+  * 
+  *  @see [[getAndTransform]] and [[transformAndGet]].
+  *        
+  * @define atomicTransformBestPractices Best practices ...
+  *  
+  *  (1) This method will loop until the transaction succeeds in replacing
+  *  the current value. If the atomic reference is contended by multiple
+  *  actors trying to update the underlying value, then the transaction
+  *  gets repeated until it succeeds. Therefore the given function 
+  *  MUST BE pure (i.e. MUST NOT do any I/O).
+  *  
+  *  (2) State stored in this atomic reference must be an immutable
+  *  data-structure, or at least an effectively mutable one. If you
+  *  mutate the state stored in this atomic reference, working with it
+  *  is useless, as it cannot provide any transactional or visibility
+  *  guarantees. The only updates that you should allow are the updates
+  *  managed via this atomic reference.
+  *         
+  * @define atomicTransformExtractParamF is a function that receives the 
+  *  current value as input and
+  *  returns a tuple, representing (1) what the transaction yields 
+  *  after it succeeds and (2) what the update is. Note that this
+  *  function mirrors `S => (A, S)`, which is the signature of the
+  *  "state monad" 😉
+  * 
+  * @define atomicTransformExtractReturn whatever was extracted by your 
+  *  function, once the operation succeeds.
+  * 
+  * @define atomicTransformAndGetDesc Updates this atomic reference in a
+  *  transaction, modeled with  a `compareAndSet`-driven loop.
+  *  Returns the updated value.
+  * 
+  *  Sample: 
+  *  {{{
+  *    import monix.execution.atomic._
+  *         
+   *    final class CountDown0(state: AtomicLong) {
+  *      def next(): Boolean = {
+  *        val n = state.transformAndGet(n => math.max(n - 1, 0))
+   *        n > 0
+   *      }
+   *    }
+   *
+   *    val c0 = new CountDown0(Atomic(10L))
+   *    val _ = c0.next()
+   *  }}}
+  * 
+  *  @see [[getAndTransform]] and [[transformAndExtract]].
+  * 
+  * @define atomicTransformParam is a function that receives the current 
+  *  value as input and returns the `update` which is the new value that 
+  *  should be persisted. WARN — function could be called multiple times 
+  *  and should be pure!
+  * 
+  * @define atomicTransformAndGetReturn returns the updated value, once
+  *  the transaction succeeds.
+  *
+  * @define atomicGetAndTransformDesc Updates this atomic reference in a
+  *  transaction, modeled with a `compareAndSet`-driven loop.
+  *  Returns the value visible prior to the update.
+  * 
+  *  Sample: 
+  *  {{{
+  *    import monix.execution.atomic._
+  *         
+   *    final class CountDown1(state: AtomicLong, n: Int) {
+  *      def next(): Boolean = {
+  *        val i = state.getAndTransform(i => math.min(n, i + 1))
+   *        i < n
+   *      }
+   *    }
+   *
+   *    val c1 = new CountDown1(Atomic(0L), 10)
+   *    val _ = c1.next()
+   *  }}}
+  * 
+  *  @see [[transformAndGet]] and [[transformAndExtract]].
+  * 
+  * @define atomicGetAndTransformReturn the old value, that was visible
+  *  just prior to when the update happened.
+  * 
+  * @define atomicTransformDesc Updates this atomic reference in a 
+  *  transaction, modeled with a `compareAndSet`-driven loop.
+  * 
+  *  Similar with [[getAndTransform]], [[transformAndGet]], or 
+  *  [[transformAndExtract]], except this version doesn't return anything.
+  *  To use whenever we only care about the side-effect.
+  * 
+  *  Sample: 
+  *  {{{
+  *    import monix.execution.atomic._
+  *         
+   *    final class Counter(state: AtomicLong) {
+   *      def mark(i: Int = 1): Unit = state.transform(_ + i)
+   *      def get(): Long = state.get()   
+   *    }
+   *
+   *    val counter = new Counter(Atomic(0L))
+   *    counter.mark(1)
