 ## Architecture Decisions

- **Immutable state as primary model:** GameContext (api) holds board, history, player state — immutable, passed through the system. Each move creates a new GameContext, enabling undo/redo without side effects.
- **Observer pattern for UI decoupling:** GameEngine publishes move/state events; CommandInvoker queues moves; UI listens to events, not polling. GameEngine never imports UI code.
- **RuleSet trait encapsulates rules:** Move generation, check, castling, en passant all in RuleSet impl. GameEngine calls rules as a black box; rules don't know about the rest of core.
- **Polyglot hash must follow spec index layout:** piece keys use interleaved mapping `(pieceType * 2 + colorBit)` with black=0/white=1, castling keys are `768..771`, en-passant file keys are `772..779` and are XORed only if side-to-move has a pawn that can capture en passant, side-to-move key is `780` for white.
- **Alpha-beta uses sequential PV search by default:** parallel split was disabled because fixed-window futures removed pruning effectiveness; correctness and pruning quality take priority over speculative parallelism.
- **Search hash is updated incrementally per move:** bot search now updates Zobrist keys from parent hash with move deltas instead of recomputing piece scans at every node.

+# This Dockerfile is used in order to build a container that runs the Quarkus application in JVM mode
+#
+# Before building the container image run:
+#
+# ./gradlew build
+#
+# Then, build the image with:
+#
+# docker build -f src/main/docker/Dockerfile.jvm -t quarkus/backcore-jvm .
+#
+# Then run the container using:
+#
+# docker run -i --rm -p 8080:8080 quarkus/backcore-jvm
+#
+# If you want to include the debug port into your docker image
+# you will have to expose the debug port (default 5005 being the default) like this :  EXPOSE 8080 5005.
+# Additionally you will have to set -e JAVA_DEBUG=true and -e JAVA_DEBUG_PORT=*:5005
+# when running the container
+#
+# Then run the container using :
+#
+# docker run -i --rm -p 8080:8080 quarkus/backcore-jvm
+#
+# This image uses the `run-java.sh` script to run the application.
+# This scripts computes the command line to execute your Java application, and
+# includes memory/GC tuning.
+# You can configure the behavior using the following environment properties:
+# - JAVA_OPTS: JVM options passed to the `java` command (example: "-verbose:class") - Be aware that this will override
+# the default JVM options, use `JAVA_OPTS_APPEND` to append options
+# - JAVA_OPTS_APPEND: User specified Java options to be appended to generated options
+#   in JAVA_OPTS (example: "-Dsome.property=foo")
+# - JAVA_MAX_MEM_RATIO: Is used when no `-Xmx` option is given in JAVA_OPTS. This is
+#   used to calculate a default maximal heap memory based on a containers restriction.
+#   If used in a container without any memory constraints for the container then this
+#   option has no effect. If there is a memory constraint then `-Xmx` is set to a ratio
+#   of the container available memory as set here. The default is `50` which means 50%
+#   of the available memory is used as an upper boundary. You can skip this mechanism by
+#   setting this value to `0` in which case no `-Xmx` option is added.
+# - JAVA_INITIAL_MEM_RATIO: Is used when no `-Xms` option is given in JAVA_OPTS. This
+#   is used to calculate a default initial heap memory based on the maximum heap memory.
+#   If used in a container without any memory constraints for the container then this
+#   option has no effect. If there is a memory constraint then `-Xms` is set to a ratio
+#   of the `-Xmx` memory as set here. The default is `25` which means 25% of the `-Xmx`
+#   is used as the initial heap size. You can skip this mechanism by setting this value
+#   to `0` in which case no `-Xms` option is added (example: "25")
+# - JAVA_MAX_INITIAL_MEM: Is used when no `-Xms` option is given in JAVA_OPTS.
+#   This is used to calculate the maximum value of the initial heap memory. If used in
+#   a container without any memory constraints for the container then this option has
+#   no effect. If there is a memory constraint then `-Xms` is limited to the value set
+#   here. The default is 4096MB which means the calculated value of `-Xms` never will
+#   be greater than 4096MB. The value of this variable is expressed in MB (example: "4096")
+# - JAVA_DIAGNOSTICS: Set this to get some diagnostics information to standard output
+#   when things are happening. This option, if set to true, will set
+#  `-XX:+UnlockDiagnosticVMOptions`. Disabled by default (example: "true").
+# - JAVA_DEBUG: If set remote debugging will be switched on. Disabled by default (example:
+#    true").
+# - JAVA_DEBUG_PORT: Port used for remote debugging. Defaults to 5005 (example: "8787").
+# - CONTAINER_CORE_LIMIT: A calculated core limit as described in
+#   https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt. (example: "2")
+# - CONTAINER_MAX_MEMORY: Memory limit given to the container (example: "1024").
+# - GC_MIN_HEAP_FREE_RATIO: Minimum percentage of heap free after GC to avoid expansion.
+#   (example: "20")
+# - GC_MAX_HEAP_FREE_RATIO: Maximum percentage of heap free after GC to avoid shrinking.
+#   (example: "40")
+# - GC_TIME_RATIO: Specifies the ratio of the time spent outside the garbage collection.
+#   (example: "4")
+# - GC_ADAPTIVE_SIZE_POLICY_WEIGHT: The weighting given to the current GC time versus
+#   previous GC times. (example: "90")
+# - GC_METASPACE_SIZE: The initial metaspace size. (example: "20")
+# - GC_MAX_METASPACE_SIZE: The maximum metaspace size. (example: "100")
+# - GC_CONTAINER_OPTIONS: Specify Java GC to use. The value of this variable should
+#   contain the necessary JRE command-line options to specify the required GC, which
+#   will override the default of `-XX:+UseParallelGC` (example: -XX:+UseG1GC).
+# - HTTPS_PROXY: The location of the https proxy. (example: "myuser@127.0.0.1:8080")

+# This Dockerfile is used in order to build a container that runs the Quarkus application in JVM mode
+#
+# Before building the container image run:
+#
+# ./gradlew build
+#
+# Then, build the image with:
+#
+# docker build -f src/main/docker/Dockerfile.jvm -t quarkus/backcore-jvm .
+#
+# Then run the container using:
+#
+# docker run -i --rm -p 8080:8080 quarkus/backcore-jvm
+#
+# If you want to include the debug port into your docker image
+# you will have to expose the debug port (default 5005 being the default) like this :  EXPOSE 8080 5005.
+# Additionally you will have to set -e JAVA_DEBUG=true and -e JAVA_DEBUG_PORT=*:5005
+# when running the container
+#
+# Then run the container using :
+#
+# docker run -i --rm -p 8080:8080 quarkus/backcore-jvm
+#
+# This image uses the `run-java.sh` script to run the application.
+# This scripts computes the command line to execute your Java application, and
+# includes memory/GC tuning.
+# You can configure the behavior using the following environment properties:
+# - JAVA_OPTS: JVM options passed to the `java` command (example: "-verbose:class") - Be aware that this will override
+# the default JVM options, use `JAVA_OPTS_APPEND` to append options
+# - JAVA_OPTS_APPEND: User specified Java options to be appended to generated options
+#   in JAVA_OPTS (example: "-Dsome.property=foo")
+# - JAVA_MAX_MEM_RATIO: Is used when no `-Xmx` option is given in JAVA_OPTS. This is
+#   used to calculate a default maximal heap memory based on a containers restriction.
+#   If used in a container without any memory constraints for the container then this
+#   option has no effect. If there is a memory constraint then `-Xmx` is set to a ratio
+#   of the container available memory as set here. The default is `50` which means 50%
+#   of the available memory is used as an upper boundary. You can skip this mechanism by
+#   setting this value to `0` in which case no `-Xmx` option is added.
+# - JAVA_INITIAL_MEM_RATIO: Is used when no `-Xms` option is given in JAVA_OPTS. This
+#   is used to calculate a default initial heap memory based on the maximum heap memory.
+#   If used in a container without any memory constraints for the container then this
+#   option has no effect. If there is a memory constraint then `-Xms` is set to a ratio
+#   of the `-Xmx` memory as set here. The default is `25` which means 25% of the `-Xmx`
+#   is used as the initial heap size. You can skip this mechanism by setting this value
+#   to `0` in which case no `-Xms` option is added (example: "25")
+# - JAVA_MAX_INITIAL_MEM: Is used when no `-Xms` option is given in JAVA_OPTS.
+#   This is used to calculate the maximum value of the initial heap memory. If used in
+#   a container without any memory constraints for the container then this option has
+#   no effect. If there is a memory constraint then `-Xms` is limited to the value set
+#   here. The default is 4096MB which means the calculated value of `-Xms` never will
+#   be greater than 4096MB. The value of this variable is expressed in MB (example: "4096")
+# - JAVA_DIAGNOSTICS: Set this to get some diagnostics information to standard output
+#   when things are happening. This option, if set to true, will set
+#  `-XX:+UnlockDiagnosticVMOptions`. Disabled by default (example: "true").
+# - JAVA_DEBUG: If set remote debugging will be switched on. Disabled by default (example:
+#    true").
+# - JAVA_DEBUG_PORT: Port used for remote debugging. Defaults to 5005 (example: "8787").
+# - CONTAINER_CORE_LIMIT: A calculated core limit as described in
+#   https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt. (example: "2")
+# - CONTAINER_MAX_MEMORY: Memory limit given to the container (example: "1024").
+# - GC_MIN_HEAP_FREE_RATIO: Minimum percentage of heap free after GC to avoid expansion.
+#   (example: "20")
+# - GC_MAX_HEAP_FREE_RATIO: Maximum percentage of heap free after GC to avoid shrinking.
+#   (example: "40")
+# - GC_TIME_RATIO: Specifies the ratio of the time spent outside the garbage collection.
+#   (example: "4")
+# - GC_ADAPTIVE_SIZE_POLICY_WEIGHT: The weighting given to the current GC time versus
+#   previous GC times. (example: "90")
+# - GC_METASPACE_SIZE: The initial metaspace size. (example: "20")
+# - GC_MAX_METASPACE_SIZE: The maximum metaspace size. (example: "100")
+# - GC_CONTAINER_OPTIONS: Specify Java GC to use. The value of this variable should
+#   contain the necessary JRE command-line options to specify the required GC, which
+#   will override the default of `-XX:+UseParallelGC` (example: -XX:+UseG1GC).
+# - HTTPS_PROXY: The location of the https proxy. (example: "myuser@127.0.0.1:8080")
+# - HTTP_PROXY: The location of the http proxy. (example: "myuser@127.0.0.1:8080")
