+- `code_map_architecture.json` - Autoloads, design patterns, system structure
+- `code_map_flows.json` - Signal chains, scene transitions, call graphs
+- `code_map_security.json` - Input validation, error handling patterns
+- `code_map_assets.json` - Asset dependencies, licensing information
+- `code_map_metadata.json` - Code quality metrics, test coverage, TODOs

+## Diagrams
+
+**Location**: `diagrams/` subdirectory (also copied to `docs/generated/diagrams/` for standalone viewing)
+
+**Contents**:
+- `*.mmd` - Mermaid source files (architecture, signal flows, scene hierarchy, dependencies)
+- `*.png` - Rendered PNG diagrams
+
+**Note**: Diagrams are automatically copied to `docs/generated/diagrams/` when generating documentation.
+
+## Format

+
+Guidance for Claude Code (claude.ai/code) when working with this repository.
+
+## Required Context Files
+
+Before doing anything else, get the following files in context:
+- **docs/ARCHITECTURE.md** - System design, autoloads, architectural patterns
+- **docs/CODE_OF_CONDUCT.md** - Coding standards, naming conventions, best practices
+- **project.godot** - Input actions and autoload definitions
+
+## Auto-Generated Machine-Readable Documentation
+
+**⚠️ IMPORTANT**: Before starting development, generate fresh code maps for current codebase context:
+
+```bash
+python tools/generate_code_map.py
+```
+
+This generates machine-readable JSON maps optimized for LLM consumption in `.llm/` directory (git-ignored).
+
+**When to use**:
+- At the start of every development session
+- After major refactoring or adding new files
+- When you need current codebase structure/API reference
+
+## Core Development Rules
+
+- **Use TDD methodology** for development
+- **Use static data types** in all GDScript code
+- **Keep documentation up to date** when making changes
+- **Always run tests**: `./tools/run_development.py --yaml --silent`

+## Code Maps (LLM Development Workflow)
+
+Machine-readable code intelligence for LLM-assisted development.
+
+### Quick Reference: Which Map to Load?
+
+| Task | Load This Map | Size | Contains |
+|------|---------------|------|----------|
+| Adding/modifying functions | `code_map_api.json` | ~47KB | Function signatures, parameters, return types |
+| System architecture work | `code_map_architecture.json` | ~32KB | Autoloads, design patterns, structure |
+| Signal/scene connections | `code_map_flows.json` | ~7KB | Signal chains, scene transitions |
+| Input validation/errors | `code_map_security.json` | ~12KB | Validation patterns, error handling |
+| Asset/resource management | `code_map_assets.json` | ~12KB | Dependencies, preloads, licensing |
+| Code metrics/statistics | `code_map_metadata.json` | ~300B | Stats, complexity metrics |
+
+### Generated Files (Git-Ignored)
+
+**Location**: `.llm/` directory (automatically excluded from git)
+
+**Format**: All JSON files are minified (no whitespace) for optimal LLM token efficiency.
+
+**Total size**: ~110KB if loading all maps (recommended: load only what you need)
+
+### Generating Code Maps
+
+```bash
+# Generate everything (default behavior - maps + diagrams + docs + metrics)
+python tools/generate_code_map.py
+
+# Generate only specific outputs
+python tools/generate_code_map.py --diagrams  # Diagrams only
+python tools/generate_code_map.py --docs      # Documentation only
+python tools/generate_code_map.py --metrics   # Metrics dashboard only
+
+# Explicitly generate all (same as no arguments)
+python tools/generate_code_map.py --all
+
+# Via development workflow tool
+python tools/run_development.py --codemap
+
+# Custom output location (single JSON file)
+python tools/generate_code_map.py --output custom_map.json
+
+# Skip PNG rendering (Mermaid source only)
+python tools/generate_code_map.py --diagrams --no-render
+```
+
+**New Features**:
+- **Diagrams**: Auto-generated diagrams (architecture, signal flows, scene hierarchy, dependencies) rendered to PNG using matplotlib
+- **Documentation**: Human-readable markdown docs with embedded diagrams (AUTOLOADS_API.md, SIGNALS_CATALOG.md, FUNCTION_INDEX.md, etc.)
+- **Metrics**: Markdown dashboard with statistics charts and complexity analysis
+
+### When to Regenerate
+
+Regenerate code maps when:
+- **Starting an LLM-assisted development session** - Get fresh context
+- **After adding new files** - Include new code in maps
+- **After major refactoring** - Update structure information
+- **After changing autoloads** - Capture architectural changes
+- **When onboarding new developers** - Provide comprehensive context
+
+### LLM Development Workflow
+
+1. **Generate maps**: `python tools/generate_code_map.py`
+
+2. **Load relevant maps**: Choose based on your task
+
+   **For API/Function development**:
+   ```
+   Load: .llm/code_map_api.json (~47KB)
+   Contains: All function signatures, parameters, return types, docstrings
+   ```
+
+   **For architecture/system design**:
+   ```
+   Load: .llm/code_map_architecture.json (~32KB)
+   Contains: Autoloads, design patterns, system structure
+   ```
+
+   **For signal/scene work**:
+   ```
+   Load: .llm/code_map_flows.json (~7KB)
+   Contains: Signal chains, scene transitions, connections
+   ```
+
+   **For security/validation**:
+   ```
+   Load: .llm/code_map_security.json (~12KB)
+   Contains: Input validation patterns, error handling
+   ```
+
+   **For assets/resources**:
+   ```
+   Load: .llm/code_map_assets.json (~12KB)
+   Contains: Asset dependencies, preloads, licensing
+   ```
+
+   **For metrics/stats**:
+   ```
+   Load: .llm/code_map_metadata.json (~300B)
+   Contains: Code statistics, complexity metrics
+   ```
+
+3. **Use selectively**:
+   - Load only maps relevant to current task
+   - Reduces token usage and improves focus
+   - Can always add more context later
+   - Total size if loading all: ~110KB minified JSON
+
+## Essential Coding Patterns
+
+### Scene Management
+```gdscript
+# ✅ Correct - Use GameManager
+GameManager.start_game_with_mode("match3")
+
+# ❌ Wrong - Never call directly
+get_tree().change_scene_to_file("res://scenes/game/Game.tscn")
+```
+
+### Logging
+```gdscript
+# ✅ Correct - Use DebugManager with categories
+DebugManager.log_info("Scene loaded successfully", "GameManager")
+DebugManager.log_error("Failed to load resource", "AssetLoader")
+
+# ❌ Wrong - Never use plain print/push_error
+print("Scene loaded")  # No structure, no category
+push_error("Failed")   # Missing context
+```
+
+### Memory Management
+```gdscript
+# ✅ Correct - Use queue_free()
+for child in children_to_remove:
+    child.queue_free()
+await get_tree().process_frame  # Wait for cleanup
+
+# ❌ Wrong - Never use free()
+child.free()  # Immediate deletion causes crashes
+```
+
+### Input Validation
+```gdscript
+# ✅ Correct - Validate all inputs
+func set_volume(value: float) -> bool:
+    if value < 0.0 or value > 1.0:
+        DebugManager.log_error("Invalid volume: " + str(value), "Settings")
+        return false
+    # Process validated input
+
+# ❌ Wrong - No validation
+func set_volume(value: float):
+    volume = value  # Could be negative or > 1.0
+```

+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 2025  Vladimir @nett00n Budylnikov
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.

+# System Architecture
+
+High-level architecture guide for the Skelly project, explaining system design, architectural patterns, and design decisions.
+
+**Quick Links**:
+- **Coding Standards**: See [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md)
+- **Testing Protocols**: See [TESTING.md](TESTING.md)
+- **Component APIs**: See [UI_COMPONENTS.md](UI_COMPONENTS.md)
+
+## Overview
+
+Skelly uses a service-oriented architecture with **autoload managers** providing global services, **scene-based components** implementing gameplay, and **signal-based communication** for loose coupling.
+
+**Key Architectural Principles**:
+- **Instance-based design**: No global static state for testability
+- **Signal-driven communication**: Loose coupling between systems
+- **Service layer pattern**: Autoloads as singleton services
+- **State machines**: Explicit state management for complex flows
+- **Defensive programming**: Input validation, error recovery, fallback mechanisms
+
+## Autoload System
+
+Autoloads provide singleton services accessible globally. Each has a specific responsibility.
+
+### GameManager
+**Responsibility**: Scene transitions and game state coordination
+
+**Key Features**:
+- Centralized scene loading with error handling
+- Race condition protection via `is_changing_scene` flag
+- Scene path constants for maintainability
+- Gameplay mode validation with whitelist
+- Never use `get_tree().change_scene_to_file()` directly
+
+**Usage**:
+```gdscript
+# ✅ Correct
+GameManager.start_game_with_mode("match3")
+
+# ❌ Wrong
+get_tree().change_scene_to_file("res://scenes/game/Game.tscn")
+```
+
+**Files**: `src/autoloads/GameManager.gd`
+
+### SaveManager
+**Responsibility**: Save/load game state with security and data integrity
+
+**Key Features**:
+- **Tamper Detection**: Deterministic checksums detect save file modification
+- **Race Condition Protection**: Save operation locking prevents concurrent conflicts
+- **Permissive Validation**: Auto-repair system fixes corrupted data
+- **Type Safety**: NaN/Infinity/bounds checking for numeric values
+- **Memory Protection**: File size limits prevent memory exhaustion
+- **Version Migration**: Backward-compatible save format upgrades
+- **Error Recovery**: Multi-layered backup and fallback systems
+
+**Security Model**:
+```gdscript
+# Checksum validates data integrity
+save_data["_checksum"] = _calculate_checksum(save_data)
+
+# Auto-repair fixes corrupted fields
+if not _validate_save_data(data):
+    data = _repair_save_data(data)
+
+# Race condition protection
+if _is_saving:
+    return  # Prevent concurrent saves
+```
+
+**Testing**: See [TESTING.md](TESTING.md#save-system-testing-protocols) for comprehensive test suites validating checksums, migration, and integration.
+
+**Files**: `src/autoloads/SaveManager.gd`
+
+### SettingsManager
+**Responsibility**: User settings persistence and validation
+
+**Key Features**:
+- Input validation with NaN/Infinity checks
+- Bounds checking for numeric values
+- Security hardening against invalid inputs
+- Default fallback values
+- Type coercion with validation
+
+**Files**: `src/autoloads/SettingsManager.gd`
+
+### DebugManager
+**Responsibility**: Unified logging and debug UI coordination
+
+**Key Features**:
+- Structured logging with log levels (TRACE, DEBUG, INFO, WARN, ERROR, FATAL)
+- Category-based log organization
+- Global debug UI toggle (F12 key)
+- Log level filtering for development/production
+- Replaces all `print()` and `push_error()` calls
+
+**Usage**: See [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md#logging-standards) for logging best practices.
+
+**Files**: `src/autoloads/DebugManager.gd`
+
+### AudioManager
+**Responsibility**: Music and sound effect playback
+
+**Key Features**:
+- Audio bus system (Music, SFX)
+- Volume control per bus
+- Loop configuration for music
+- UI click sounds
+
+**Files**: `src/autoloads/AudioManager.gd`
+
+### LocalizationManager
+**Responsibility**: Language switching and translation management
+
+**Key Features**:
+- Multi-language support (English, Russian)
+- Runtime language switching
+- Translation file management
+
+**Files**: `src/autoloads/LocalizationManager.gd`
+
+## Scene Management Pattern
+
+All scene transitions flow through **GameManager** to ensure consistent error handling and state management.
+
+### Scene Loading Flow
+
+```
+User Action
+    ↓
+GameManager.start_game_with_mode(mode)
+    ↓
+Validate mode (whitelist check)
+    ↓
+Check is_changing_scene flag
+    ↓
+Load PackedScene with validation
+    ↓
+change_scene_to_packed()
+    ↓
+Reset is_changing_scene flag
+```
+
+### Race Condition Prevention
+
+```gdscript
+var is_changing_scene: bool = false
+
+func start_game_with_mode(gameplay_mode: String) -> void:
+    # Prevent concurrent scene changes
+    if is_changing_scene:
+        DebugManager.log_warn("Scene change already in progress", "GameManager")
+        return
+
+    is_changing_scene = true
+    # ... scene loading logic ...
+    is_changing_scene = false
+```
+
+**Why This Matters**: Multiple rapid button clicks or input events could trigger concurrent scene loads, causing crashes or undefined state.
+
+## Modular Gameplay System
+
+Game modes are implemented as separate gameplay modules in `scenes/game/gameplays/`.
+
+### Gameplay Architecture
+
+```
+Game.tscn (Main scene)
+    ↓
+    ├─> Match3Gameplay.tscn (Match-3 mode)
+    ├─> ClickomaniaGameplay.tscn (Clickomania mode)
+    └─> [Future gameplay modes]
+```
+
+**Pattern**: Each gameplay mode:
+- Extends Control or Node2D
+- Emits `score_changed` signal
+- Implements `_ready()` for initialization
+- Handles input independently
+- Includes optional debug menu
+
+**Files**: `scenes/game/gameplays/`
+
+## Design Patterns Used
+
+### Instance-Based Architecture
+
+**Problem**: Static variables prevent testing and create hidden dependencies.
+
+**Solution**: Instance-based architecture with explicit dependencies.
+
+```gdscript
+# ❌ Bad: Static global state
+static var current_gem_pool = [0, 1, 2, 3, 4]
+
+# ✅ Good: Instance-based
+var active_gem_types: Array = []
+
+func set_active_gem_types(gem_indices: Array) -> void:
+    active_gem_types = gem_indices.duplicate()
+```
+
+**Benefits**:
+- Each instance isolated for testing
+- No hidden global state
+- Explicit dependencies
+- Thread-safe by default
+
+### Signal-Based Communication
+
+**Pattern**: Use signals for loose coupling between systems.
+
+```gdscript
+# Component emits signal
+signal score_changed(new_score: int)
+
+# Parent connects to signal
+gameplay.score_changed.connect(_on_score_changed)
+```
+
+**Benefits**:
+- Loose coupling
+- Easy to test components in isolation
+- Clear event flow
+- Flexible subscription model
+
+### Service Layer Pattern
+
+Autoloads act as singleton services providing global functionality.
+
+**Pattern**:
+- Autoloads expose public API methods
+- Components call autoload methods
+- Autoloads emit signals for state changes
+- Never nest autoload calls deeply
+
+### State Machine Pattern
+
+Complex workflows use explicit state machines.
+
+**Example**: Match-3 tile swapping
+```
+WAITING → SELECTING → SWAPPING → PROCESSING → WAITING
+```
+
+**Benefits**:
+- Clear state transitions
+- Easy to debug
+- Prevents invalid state combinations
+- Self-documenting code
+
+## Critical Architecture Decisions
+
+### Memory Management: queue_free() Over free()
+
+**Decision**: Always use `queue_free()` instead of `free()` for node cleanup.
+
+**Rationale**:
+- `free()` causes immediate deletion (crashes if referenced)
+- `queue_free()` waits until safe deletion point
+- Prevents use-after-free bugs
+
+**Implementation**:
+```gdscript
+# ✅ Correct
+for child in children_to_remove:
+    child.queue_free()
+await get_tree().process_frame  # Wait for cleanup
+
+# ❌ Dangerous
+for child in children_to_remove:
+    child.free()  # Can crash
+```
+
+**Impact**: Eliminated multiple potential crash points. See [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md#memory-management-standards) for standards.
+
+### Race Condition Prevention: State Flags
+
+**Decision**: Use state flags to prevent concurrent operations.
+
+**Rationale**:
+- Async operations can overlap without protection
+- Multiple rapid inputs can trigger race conditions
+- State flags provide simple, effective protection
+
+**Implementation**: Used in GameManager (scene loading), SaveManager (save operations), and gameplay systems (tile swapping).
+
+### Error Recovery: Fallback Mechanisms
+
+**Decision**: Provide fallback behavior for all critical failures.
+
+**Rationale**:
+- Games should degrade gracefully, not crash
+- User experience > strict validation
+- Log errors but continue operation
+
+**Examples**:
+- Settings file corrupted? Load defaults
+- Scene load failed? Return to main menu
+- Audio file missing? Continue without sound
+
+### Input Validation: Whitelist Approach
+
+**Decision**: Validate all user inputs against known-good values.
+
+**Rationale**:
+- Security hardening
+- Prevent invalid state
+- Clear error messages
+- Self-documenting code
+
+**Implementation**: Used in SettingsManager (volume, language), GameManager (gameplay modes), Match3Gameplay (grid movements).
+
+## System Interactions
+
+### Typical Game Flow
+
+```
+Main Menu
+    ↓
+    [GameManager.start_game_with_mode("match3")]
+    ↓
+Game Scene Loads
+    ↓
+Match3Gameplay initializes
+    ↓
+    ├─> SettingsManager (load difficulty)
+    ├─> AudioManager (play background music)
+    └─> DebugManager (setup debug UI)
+    ↓
+Gameplay Loop
+    ↓
+    ├─> Input handling
+    ├─> Score updates (emit score_changed signal)
+    ├─> SaveManager (autosave high score)
+    └─> DebugManager (log important events)
+```
+
+### Signal Flow Example: Score Change
+
+```
+Match3Gameplay detects match
+    ↓
+    [emit score_changed(new_score)]
+    ↓
+Game.gd receives signal
+    ↓
+Updates score display UI
+    ↓
+SaveManager.save_high_score(score)
+```
+
+### Debug System Integration
+
+```
+User presses F12
+    ↓
+DebugManager.toggle_debug_ui()
+    ↓
+    [emit debug_ui_toggled(visible)]
+    ↓
+All debug menus receive signal
+    ↓
+Show/hide debug panels
+```
+
+## Quality Improvements
+
+The project implements high-quality code standards from the start:
+
+**Key Quality Features**:
+- **Memory Safety**: Uses `queue_free()` pattern for safe node cleanup
+- **Error Handling**: Comprehensive error handling with fallbacks
+- **Race Condition Protection**: State flag protection for async operations
+- **Instance-Based Architecture**: No global static state for testability
+- **Code Reuse**: Base class architecture (DebugMenuBase) for common functionality
+- **Input Validation**: Complete validation coverage for all user inputs
+
+These standards are enforced through the [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md#code-quality-checklist) quality checklist.
+
+## Best Practices
+
+### Extending the Architecture
+
+When adding new features:
+
+1. **New autoload?**
+   - Only if truly global and used by many systems
+   - Consider dependency injection instead
+   - Keep autoloads focused on single responsibility
+
+2. **New gameplay mode?**
+   - Create in `scenes/game/gameplays/`
+   - Extend appropriate base class
+   - Emit `score_changed` signal
+   - Add to GameManager mode whitelist
+
+3. **New UI component?**
+   - Create in `scenes/ui/components/`
+   - Follow [UI_COMPONENTS.md](UI_COMPONENTS.md) patterns
+   - Support keyboard/gamepad navigation
+   - Emit signals for state changes
+
+### Architecture Review Checklist
+
+Before committing architectural changes:
+
+- [ ] No new global static state introduced
+- [ ] All autoload access justified and documented
+- [ ] Signal-based communication used appropriately
+- [ ] Error handling with fallbacks implemented
+- [ ] Input validation in place
+- [ ] Memory management uses `queue_free()`

-- **Checksum validation**: Test `test_checksum_issue.gd` to verify deterministic checksums
-- **Migration compatibility**: Run `TestMigrationCompatibility.gd` for version upgrades
-
-### Common Implementation Patterns
-- **Scene transitions**: Use `GameManager.start_game_with_mode()` with built-in validation
-- **Debug integration**: Connect to `DebugManager` signals and initialize debug state
-- **Logging**: Use `DebugManager.log_*()` functions with appropriate levels and categories
-- **Gameplay modes**: Implement in `scenes/game/gameplays/` directory following modular pattern
-- **Scoring system**: Connect `score_changed` signal from gameplay to main game scene
-- **Save/Load operations**: Use `SaveManager` with security and validation
-- **Settings**: Use `SettingsManager` with input validation, NaN/Infinity checks, and security hardening
-- **Audio**: Use `AudioManager` for music and sound effects
-- **Localization**: Use `LocalizationManager` for language switching
-- **UI Components**: Extend `DebugMenuBase` for debug menus to avoid code duplication
-- **Value Selection**: Use `ValueStepper` component for discrete option selection (language, resolution, difficulty)
-- **Memory Management**: Use `queue_free()` and await frame completion for safe cleanup
-- **Input Validation**: Validate user inputs with type checking and bounds validation
-
-### Logging Best Practices
-```gdscript
-# Good logging
-DebugManager.log_info("Scene transition completed", "GameManager")
-DebugManager.log_warn("Settings file not found, using defaults", "Settings")
-DebugManager.log_error("Failed to load audio resource: " + audio_path, "AudioManager")
-
-# Avoid
-print("debug")  # Use structured logging instead
-push_error("error")  # Use DebugManager.log_error() with category
-```
-
-### Asset Management Workflow
-```yaml
-# ✅ Required assets/sources.yaml entry format
-audio:
-  music:
-    "background_music.ogg":
-      source: "https://freesound.org/people/artist/sounds/123456/"
-      license: "CC BY 4.0"
-      attribution: "Background Music by Artist Name"
-      modifications: "Converted to OGG, adjusted volume"
-      usage: "Main menu and gameplay background music"
-
-# ✅ Proper commit workflow
-# 1. Add asset to appropriate assets/ subdirectory
-# 2. Update assets/sources.yaml with complete metadata
-# 3. git add both files together
-# 4. Commit with descriptive message including attribution

+### Memory Management Standards
+
+**Critical Rules**:
+1. **Always use `queue_free()`** instead of `free()` for node cleanup
+2. **Wait for frame completion** after queueing nodes for removal
+3. **Clear references before cleanup** to prevent access to freed memory
+4. **Connect signals properly** for dynamically created nodes
+
+```gdscript
+# ✅ Correct memory management
+for child in children_to_remove:
+    child.queue_free()
+await get_tree().process_frame  # Wait for cleanup
+
+# ❌ Dangerous pattern (causes crashes)
+for child in children_to_remove:
+    child.free()  # Immediate deletion can crash
+```
+
+**Why This Matters**: Using `free()` causes immediate deletion which can crash if the node is still referenced elsewhere. `queue_free()` waits until it's safe to delete.
+
+**See Also**: [ARCHITECTURE.md](ARCHITECTURE.md#memory-management-queue_free-over-free) for architectural rationale.
+
+### Input Validation Standards
+
+All user inputs must be validated before processing.
+
+**Validation Requirements**:
+1. **Type checking**: Verify input types before processing
+2. **Bounds checking**: Validate numeric ranges and array indices
+3. **Null checking**: Handle null and empty inputs gracefully
+4. **Whitelist validation**: Validate against known good values
+
+```gdscript
+# ✅ Proper input validation
+func set_volume(value: float, setting_key: String) -> bool:
+    # Whitelist validation
+    if not setting_key in ["master_volume", "music_volume", "sfx_volume"]:
+        DebugManager.log_error("Invalid volume setting key: " + str(setting_key), "Settings")
+        return false
+
+    # Bounds checking
+    var clamped_value = clamp(value, 0.0, 1.0)
+    if clamped_value != value:
+        DebugManager.log_warn("Volume value clamped from %f to %f" % [value, clamped_value], "Settings")
+
+    SettingsManager.set_setting(setting_key, clamped_value)
+    return true
+
+# ✅ Grid movement validation
+func _move_cursor(direction: Vector2i) -> void:
+    # Bounds checking
+    if abs(direction.x) > 1 or abs(direction.y) > 1:
+        DebugManager.log_error("Invalid cursor direction: " + str(direction), "Match3")
+        return
+
+    # Null/empty checking
+    if not grid or grid.is_empty():
+        DebugManager.log_error("Grid not initialized", "Match3")
+        return
+
+    # Process validated input
+    var new_pos = cursor_pos + direction
+    # ... continue with validated data
+```
+
+**See Also**: [ARCHITECTURE.md](ARCHITECTURE.md#input-validation-whitelist-approach) for architectural decision rationale.

-func set_active_gem_types(gem_indices: Array) -> void:
-    if not gem_indices or gem_indices.is_empty():
-        DebugManager.log_error("Empty gem indices array", "Tile")
-        return
-    active_gem_types = gem_indices.duplicate()
-
-# ❌ Static global state (now eliminated)
-static var current_gem_pool = [0, 1, 2, 3, 4]
-static func set_active_gem_pool(gem_indices: Array) -> void:
-    current_gem_pool = gem_indices.duplicate()
-```
-
-**Files Improved:**

+
+## Development Workflows
+
+### Adding a New Feature
+
+1. **Generate code maps** for LLM context:
+   ```bash
+   python tools/generate_code_map.py
+   ```
+
+2. **Review architecture** to understand system design:
+   - Read [ARCHITECTURE.md](ARCHITECTURE.md) for relevant system
+   - Understand autoload responsibilities
+   - Review existing patterns
+
+3. **Follow coding standards**:
+   - Use [naming conventions](CODE_OF_CONDUCT.md#naming-convention-quick-reference)
+   - Follow [core patterns](CODE_OF_CONDUCT.md#project-specific-guidelines)
+   - Implement [input validation](CODE_OF_CONDUCT.md#input-validation-standards)
+   - Use [proper memory management](CODE_OF_CONDUCT.md#memory-management-standards)
+
+4. **Write tests** for new functionality:

+   - Follow [test structure guidelines](TESTING.md#adding-new-tests)
+   - Run tests to verify functionality
+
+5. **Check quality checklist** before committing:
+   - Review [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md#code-quality-checklist)
+   - Verify all checkboxes are satisfied
+   - Run tests one more time
+
+### Debugging Issues
+
+1. **Toggle debug UI** with F12 in-game:
+   - View system state in debug panels
+   - Check current values and configurations
+   - Use debug controls for testing
+
+2. **Check logs** using structured logging:
+   ```gdscript
+   DebugManager.log_debug("Detailed debug info", "MyComponent")
+   DebugManager.log_info("Important event occurred", "MyComponent")
+   DebugManager.log_warn("Unexpected situation", "MyComponent")
+   DebugManager.log_error("Something failed", "MyComponent")
+   ```
+
+3. **Verify state** in debug panels:
+   - Match-3: Check gem pool, grid state, match detection
+   - Settings: Verify volume, language, difficulty values
+   - Save: Check save data integrity
+
+4. **Run relevant test scripts**:
+   ```bash
+   # Test specific system
+   godot --headless --script tests/TestMatch3Gameplay.gd
+   godot --headless --script tests/TestSettingsManager.gd
+   ```
+
+5. **Use Godot debugger**:
+   - Set breakpoints in code
+   - Inspect variables during execution
+   - Step through code execution
+   - Use remote inspector for live debugging
+
+### Modifying Core Systems
+
+1. **Understand current design**:
+   - Read [ARCHITECTURE.md](ARCHITECTURE.md) for system architecture
+   - Review autoload responsibilities
+   - Understand signal flows and dependencies
+
+2. **Run existing tests first**:
+   ```bash
+   # Save system testing
+   godot --headless --script tests/test_checksum_issue.gd
+   godot --headless --script tests/TestMigrationCompatibility.gd
+
+   # Settings testing
+   godot --headless --script tests/TestSettingsManager.gd
+
+   # Game manager testing
+   godot --headless --script tests/TestGameManager.gd
+   ```
+
+3. **Make changes following standards**:
+   - Follow [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md) patterns
+   - Maintain backward compatibility where possible
+   - Add input validation and error handling
+   - Use proper memory management
+
+4. **Run tests again** to verify no regressions:
+   ```bash
+   # Run all relevant test suites
+   python tools/run_development.py --test
+   ```
+
+5. **Update documentation** if architecture changes:
+   - Update [ARCHITECTURE.md](ARCHITECTURE.md) if design patterns change
+   - Update [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md) if new patterns emerge
+   - Update [TESTING.md](TESTING.md) if new test protocols needed
+

+```
+
+See [TESTING.md](TESTING.md) for complete testing protocols.
+
+## Troubleshooting
+
+### When Stuck
+
+1. **Check system design**: Read [ARCHITECTURE.md](ARCHITECTURE.md) for understanding
+2. **Review coding patterns**: Check [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md) for examples
+3. **Use debug system**: Press F12 to inspect current state
+4. **Search existing code**: Look for similar patterns in the codebase
+5. **Test understanding**: Create small experiments to verify assumptions
+
+### Common Issues
+
+#### Scene Loading Fails
+**Problem**: Scene transitions not working or crashes during scene change
+
+**Solution**:
+- Check if using `GameManager.start_game_with_mode()` (correct)
+- Never use `get_tree().change_scene_to_file()` directly
+- Verify scene paths are correct constants in GameManager
+- Check for race conditions (multiple rapid scene changes)
+
+**Example**:
+```gdscript
+# ✅ Correct
+GameManager.start_game_with_mode("match3")
+
+# ❌ Wrong
+get_tree().change_scene_to_file("res://scenes/game/Game.tscn")
+```
+
+#### Logs Not Appearing
+**Problem**: Debug messages not showing in console
+
+**Solution**:
+- Use `DebugManager.log_*()` functions instead of `print()`
+- Include category for log organization
+- Check log level filtering (TRACE/DEBUG require debug mode)
+- Verify DebugManager is configured as autoload
+
+**Example**:
+```gdscript
+# ✅ Correct
+DebugManager.log_info("Scene loaded", "GameManager")
+DebugManager.log_error("Failed to load resource", "AssetLoader")
+
+# ❌ Wrong
+print("Scene loaded")  # Use structured logging
+push_error("Failed")   # Missing context and category
+```
+
+#### Memory Crashes
+**Problem**: Crashes related to freed nodes or memory access
+
+**Solution**:
+- Always use `queue_free()` instead of `free()`
+- Wait for frame completion after queueing nodes
+- Clear references before cleanup
+- Check for access to freed objects
+
+**Example**:
+```gdscript
+# ✅ Correct
+for child in children_to_remove:
+    child.queue_free()
+await get_tree().process_frame  # Wait for cleanup

+```
+
+#### Tests Failing
+**Problem**: Test scripts fail or hang
+
+**Solution**:
+- Run tests in sequence (avoid parallel execution)
+- Check autoload configuration in project.godot
+- Remove existing save files before testing SaveManager
+- Verify test file permissions
+- Check test timeout (should complete within seconds)
+
+#### Input Not Working
+**Problem**: Keyboard/gamepad input not responding
+
+**Solution**:
+- Verify input actions defined in project.godot
+- Check input map configuration
+- Ensure scene has input focus
+- Test with both keyboard and gamepad
+- Check for input event consumption by UI elements
+
+## Best Practices
+
+### Before Committing
+
+1. **Run all relevant tests**:
+   ```bash
+   python tools/run_development.py --test
+   ```
+
+2. **Check quality checklist**: [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md#code-quality-checklist)
+
+3. **Verify no regressions**: Test existing functionality
+
+4. **Update documentation**: If patterns or architecture changed
+
+5. **Review changes**: Use `git diff` to review all modifications
+
+### Code Review
+
+- Focus on code clarity and maintainability
+- Check adherence to project patterns
+- Verify input validation and error handling
+- Ensure memory management is safe
+- Test the changes yourself before approving
+
+### Performance Considerations
+
+- Profile critical code paths
+- Use object pooling for frequently created nodes
+- Optimize expensive calculations
+- Cache node references with `@onready`
+- Avoid searching nodes repeatedly in `_process()`
