+## Development Setup
+
+Use Java 25 or newer. The Gradle wrapper downloads Gradle 9.8; dependencies are declared in `build.gradle` and resolved from Maven Central, PaperMC, and EngineHub.
+
+```sh
+./gradlew build
+```
+
+The standard build runs JUnit 5 tests without starting Minecraft. Tests use Mockito for Bukkit and external-plugin boundaries. Keep domain and configuration behavior testable without a running server.
+
+## Live Server Tests
+
+Live tests are opt-in and run separately from `build`:
+
+```sh
+METROPOLIS_RCON_HOST=127.0.0.1 \
+METROPOLIS_RCON_PORT=25575 \
+METROPOLIS_RCON_PASSWORD=... \
+METROPOLIS_SERVER_DIR=/path/to/server \
+./gradlew integrationTest
+```
+
+Use a disposable or backed-up Paper server with compatible WorldGuard and WorldEdit plugin jars installed. Keep RCON local, use a temporary password, and restore the server after tests that modify regions or worlds.
+
+## Pull Requests
+
+- Keep changes focused and include tests for behavior changes.
+- Run `./gradlew build` before submitting.
+- Run `integrationTest` only when changing behavior that requires Paper or the external plugins; do not add it to the default build.
+- Update `README.md` and project descriptions when user-facing setup, commands, or dependencies change.
+- Keep generated build output, server data, credentials, and local `.env` files out of commits.

+# Metropolis Human Testing
+
+Use this checklist for behavior that depends on a real Paper world, player interactions, or the installed WorldGuard and WorldEdit plugins. Automated tests cover some isolated logic, but they do not establish that the complete in-game workflows behave correctly.
+
+## Test Environment
+
+- Use a disposable Paper 26.2 or 26.3 server with Java 25+, WorldGuard 7.0.19, WorldEdit 7.4.5, and Metropolis installed.
+- Back up the server before testing. Home generation, reservations, and configuration can change world blocks and WorldGuard regions.
+- Use at least two non-operator player accounts for ownership and protection checks. Operators can bypass protection and hide permission problems.
+- Keep a server console open and check it for errors after startup, commands, joins, and restarts.
+- Record the Metropolis config, world name, test player UUIDs, command output, and any unexpected region bounds or block changes.
+
+## Human Checklist
+
+### Startup and world setup
+
+- Start with the required plugins enabled. Confirm Metropolis enables without errors and its commands are registered. Also confirm startup fails clearly if a required dependency or configured world is missing, then restore the valid setup.
+- On a fresh test world, inspect the `City` and `Spawn` WorldGuard regions. Check their bounds, flags, and priority; verify the configured spawn generation and world-spawn location.
+- Restart once with existing regions. Confirm Metropolis recognizes them instead of duplicating or resetting them, and that existing city bounds and player homes remain intact.
+
+### Join and plot allocation
+
+- Join as a new player. Confirm one home is allocated and the welcome message reports its actual bounds. Check the corresponding `h_1_<UUID>` region has the player as owner and its bounds match the configured plot size.
+- Join with a second new player. Confirm the new home is distinct, does not overlap the first home or spawn, and the City region grows to include it.
+- Join again as an existing player. Confirm the same home is selected and no duplicate region or plot is created.
+- Reserve an area before allocating another home. Confirm future allocations skip it. Repeat with reservations near the city edge and near existing roads to look for overlaps or gaps.
+- Test a user override that grants a different plot multiplier or home limit. Confirm the generated bounds and allowed number of homes match the override, and that the configured global defaults still apply to other players.
+
+### Generated blocks and geometry
+
+- Inspect a newly allocated home and adjoining roads. Check road width, level, material, clearance, plot floor, support blocks, and optional sign against the active config.
+- Test generation over varied terrain, including water, caves, uneven ground, and existing structures. Confirm generated floors and roads do not leave unsafe gaps or erase blocks outside their intended area.
+- Enable and disable optional floor, support, sign, spawn, world-spawn, and perimeter-wall settings one at a time on a disposable world. Confirm each setting changes only its intended behavior.
+- Allocate plots in several directions and near the world origin. Check road joins, plot dimensions, City region expansion, and boundary coordinates for symmetry and off-by-one errors.
+
+### Reservations and protection
+
+- Reserve one plot with explicit coordinates. Then make a WorldEdit selection and reserve a second plot using `/metropolis-plot-reserve <name>`.
+- Try invalid coordinates, a duplicate region name, and bounds that intersect a home or another reservation. Confirm the command reports a useful failure and does not silently overwrite an existing region.
+- Check `/metropolis-home-list` and `/metropolis-plot-go <plotName>` for both occupied homes and reservations; confirm teleport destinations are safe and inside the requested plot.
+- As the home owner, build and interact inside the home. As another non-op player, try the same actions. Verify ownership and protection behave as intended in homes, reservations, City, and Spawn.
+- Verify representative protection flags in-game, including PvP, mob damage/spawning, explosions, and fire/lava behavior where applicable. Run `/metropolis-flag-reset` and confirm the expected flags are restored without changing region bounds or ownership.
+- Restart the server and confirm reservations and their protection are still present in WorldGuard and remain excluded from home allocation.
+
+### Commands, permissions, and player state
+
+- For a new player with no overrides, join and confirm exactly one `h_1_<UUID>` home is created. Rejoin and confirm no additional home is created.
+- Configure two `permissionOverrides` tiers in `plugins/Metropolis/config.yml`, then restart. Grant each permission node to a test user and to a test group through the server's permission manager. Confirm the player's effective `plotMultiplier` and `maxPlots` match the granted rule.
+- Give one player multiple configured permission nodes with different priorities. Confirm the highest-priority rule controls both values; then give two matching rules the same priority and confirm the last matching YAML entry wins.
+- Give a player both a permission tier and a matching `userOverrides` entry. Confirm the username override wins. Remove both overrides from another player and confirm `plot.multiplier` and `plot.maxPerPlayer` are used as defaults.
+- Change or revoke a permission while the player is online, then acquire another home. Confirm the next acquisition uses the currently granted tier without requiring a restart.
+- With plot multipliers of 1 and 2, acquire homes and inspect their WorldGuard bounds. Confirm size follows the tier, a larger footprint does not overlap an existing home, and the multiplier is applied to the X and Z footprint only once.
+- Exercise `/metropolis-home-acquire` below and at each effective home limit. Confirm every successful request creates a distinct next-numbered home, creates none beyond the limit, and does not change other players' homes.
+- After acquiring a second home, verify it becomes active: check the player's selected home in `plugins/Metropolis/currentHomes.yml` and use `/metropolis-home-go` to confirm travel to that home. Switch homes with `/metropolis-home-move` and verify the selection changes as expected.
+- Run `/metropolis-home-move <homeNumber>` as a player with multiple homes. Verify the command confirms the selected home, updates `currentHomes.yml`, and `/metropolis-home-go` now travels to it.
+- Run `/metropolis-home-move <homeNumber> <playerName>` as an authorized administrator, then repeat from console. Check an online target is notified and a cached offline target uses the selected home on their next join.
+- Try zero, negative, non-numeric, nonexistent home numbers, unknown player names, and extra arguments. Confirm each request is rejected with useful feedback and does not change the stored active home.
+- Restart after acquiring multiple homes. Confirm all home regions remain owned by the player, the active home selection persists, and joining does not allocate another first home.
+- Generate a home for an offline player administratively. Confirm permission tiers are not assumed for offline players; the username override or global settings determine plot size and limit.
+- Exercise `/metropolis-home-go` with a safe bed spawn inside the home and with no such bed spawn. Confirm teleportation chooses a valid location inside the home and reports a clear failure if no safe location exists.
+- Exercise `/metropolis-home-move` for a player with multiple homes. Confirm the selected home persists across reconnect and restart; reject nonexistent home numbers.
+- As an administrator, test `/metropolis-home-generate`, `/metropolis-home-evict`, and `/metropolis-home-list` with online and previously seen offline players. Confirm the intended region ownership changes, persistence, and subsequent allocation behavior.
+- Test commands as console, permitted player, and player without the relevant permission. Check player-only commands, target-player arguments, unknown names, malformed arguments, and permission denials for useful feedback and no unintended changes.
+- If upgrading an existing server, verify a legacy name-keyed `currentHomes.yml` entry resolves to the right UUID and the player's selected home is retained.
+
+## Existing Automated Coverage
+
+Run `./gradlew test` for the server-free JUnit suite. It has 20 tests covering:
+
+- `CuboidTest`: WorldEdit bound conversion, vector ordering/null handling, touching intersections, and point containment.
+- `CurrentHomesStoreTest`: UUID-based persistence and resolving a legacy player-name key.
+- `PlayerJoinListenerTest`: the welcome bounds message when a home is supplied by a mock.
+- `PlayerLookupTest`: case-insensitive full-name matching and rejection of prefix matching.
+- `PlayerHomeTest`: UUID-based region identity and display-name retention.
+- `HomePermissionOverrideTest`: dotted permission-node parsing, priority and tie resolution, invalid entries, and username/permission/default precedence.
+- `HomeNumberAllocatorTest`: choosing the first unused positive home number.
+- `MetropolisHomeMoveCommandTest`: selecting a sender's home, selecting an offline target's home, and rejecting invalid requests.
+- `MetropolisPlotReserveCommandTest`: parsing six coordinates and rejecting malformed coordinates.
+- `MetropolisHomeAcquireTest`: acquisition below the limit and refusal at the limit.
+
+The two opt-in tests in `src/integrationTest` require a running Paper server and RCON. They check that Metropolis appears in `/plugins` and that a coordinate reservation is persisted by WorldGuard. They do not currently verify restart persistence, join allocation, WorldEdit-selection reservations, permissions, teleports, generated blocks, protection behavior, or the other command workflows above. Run them with the environment variables documented in `README.md`; use a disposable server because the reservation test changes its WorldGuard data.
+
+The integration scope described in `TODO.md` is broader than the tests currently present. Treat the scenarios in this guide as unverified until a human has run them on the target Paper and plugin versions.

+**Metropolis**
+
+Metropolis grows a protected Minecraft city as players join. It assigns home plots connected by roads, expands the protected city region, and lets players and administrators manage homes and reserve plots.
+
+## Requirements
+
+- Paper 26.2 or 26.3.
+- Java 25 or newer.
+- WorldGuard 7.0.19 and WorldEdit 7.4.5.
+
+WorldGuard and WorldEdit are required dependencies. Install all three plugins in the server's `plugins` directory.
+
+Metropolis targets Paper only; Bukkit and Spigot servers are not supported.
+
+## Features
+
+- Automatically assigns a protected home plot when a player joins.
+- Allows players to acquire additional homes up to their effective limit, configured globally, per user, or through permission-manager groups.
+- Supports permission-based plot-size and home-limit tiers with configurable priorities; explicit per-user overrides take precedence.
+- Lets players and authorized administrators select an existing home as active; selections persist by player UUID across restarts.
+- Expands the protected city region as plots are occupied.
+- Configures plot dimensions, roads, floors, supports, signs, spawn behavior, and perimeter walls.
+- Reserves named plots by coordinates or a WorldEdit selection.
+- Tracks home ownership and selected homes by player UUID.
+- Supports home and plot teleportation, administration, and WorldGuard protection flags.
+
+## Configuration
+
+Metropolis creates `plugins/Metropolis/config.yml` on first startup. Configure plot limits and dimensions, roads, floors and supports, signs, spawn behavior, walls, world name, and per-player overrides. Use Bukkit material names; legacy numeric material IDs are also accepted for existing configurations.
+
+## Commands
+
+- `/metropolis` - Displays the plugin version.
+- `/metropolis-home-acquire` - Acquires another available home plot.
+- `/metropolis-home-generate <playerName>` - Generates a home for a known online or cached offline player.
+- `/metropolis-home-list` - Lists occupied and reserved plots.
+- `/metropolis-home-go [playerName]` - Teleports to a home.
+- `/metropolis-home-move <homeNumber> [playerName]` - Selects an existing home as active. The player name defaults to the sender; authorized administrators and console can target online or cached offline players.
+- `/metropolis-home-evict <playerName>` - Removes a player's ownership from their selected home region.
+- `/metropolis-plot-reserve <name> <minX> <minY> <minZ> <maxX> <maxY> <maxZ>` - Reserves a region by coordinates; players can use `/metropolis-plot-reserve <name>` with a WorldEdit selection.
+- `/metropolis-plot-go <plotName> [playerName]` - Teleports to a named plot.
+- `/metropolis-flag-reset` - Reapplies Metropolis protection flags.
+- `/metropolis-debug-generatetesthomes <count>` - Generates test homes; intended for development servers.
+
+## Build
+
+Run `./gradlew build` from the project directory. The plugin jar is created in `build/libs/`.

+# Metropolis
+
+Metropolis turns player onboarding into city planning. As players arrive, the Paper plugin finds the next available plot, builds the surrounding roads and infrastructure, and extends a WorldGuard-protected city that feels designed rather than randomly generated.
+
+The project combines procedural spatial logic, persistent UUID-based ownership, configurable construction rules, WorldEdit-assisted reservations, and a command suite for acquiring and selecting multiple homes. Home limits and plot sizes can be assigned per user or through permission-manager groups using configurable permission tiers. Active-home selections persist across reconnects and server restarts. It is also a modernization case study: a legacy plugin brought forward to Paper 26.2 and 26.3 with Gradle, focused unit tests, and opt-in live-server integration tests. Bukkit and Spigot servers are outside the support target.

-Metropolis generates a home for each user connecting to your world with roads between them. As new users connect the city expands.
-
-WorldGuard regions are used for each home and for the city as a whole.
-
-One region called "City" is created to protect the spawn and roads. As the assigned blocks expand this region is automatically updated.

+# Metropolis
+
+Metropolis expands a protected Minecraft city as players join. Each player can receive a home plot connected by generated roads; WorldGuard protects the city, homes, and reserved plots.
+
+## Features
+
+- Assigns a protected home plot when a player joins and supports acquiring additional homes up to the configured player limit.
+- Supports per-player plot sizes and home limits through `userOverrides` or configurable permission tiers; acquired homes can be selected as the active home.
+- Expands the City region as plots are occupied, with optional spawn generation, world-spawn placement, floors, support blocks, signs, and perimeter walls.
+- Generates roads around plots with configurable width, level, material, clearance, and supports.
+- Creates named protected reservations from coordinates or a WorldEdit selection so reserved plots are not assigned as homes.
+- Persists selected homes by player UUID and recognizes legacy name-based home data during migration.
+- Supports online/offline player administration for home generation, movement, and eviction.
+
+## Requirements
+
+- Paper 26.2 or 26.3, with Java 25 or newer
+- WorldGuard 7.0.19
+- WorldEdit 7.4.5
+
+WorldGuard and WorldEdit are required plugin dependencies. Install them alongside Metropolis in the server's `plugins` directory.
+
+## Build and Test
+
+Build the plugin and run the server-free unit tests:
+
+```sh
+./gradlew clean build
+```
+
+The plugin jar is written to `build/libs/`. The Gradle wrapper uses Gradle 9.8, and Git-sensitive semantic versioning derives the artifact and `plugin.yml` versions from repository tags and commits.
+
+Run the opt-in live-server tests against a running Paper server with WorldGuard, WorldEdit, and RCON enabled:
+
+```sh
+METROPOLIS_RCON_HOST=127.0.0.1 \
+METROPOLIS_RCON_PORT=25575 \
+METROPOLIS_RCON_PASSWORD=... \
+METROPOLIS_SERVER_DIR=/path/to/server \
+./gradlew integrationTest
+```
+
+`integrationTest` is separate from the normal `test` and `build` tasks. Keep RCON bound to a trusted interface and do not commit its password.
+
+## Server Scripts
+
+Copy `.env.example` to `.env` and configure the Paper version/build and server paths. The scripts read `.env` as key/value data.
+
+- `tools/build-plugin.sh` builds and tests the plugin.
+- `tools/deploy-plugin.sh` copies the Gradle-built jar to the configured server.
+- `tools/start-server.sh` downloads the configured Paper build if needed and starts it.
+- `tools/backup-server.sh` and `tools/restore-server.sh` back up or restore the configured server.
+- `tools/publish-local.sh` publishes the artifact to the local Maven repository.
+- `tools/publish-modrinth.sh` uploads a built jar after checking its version and generates a Markdown changelog from Git commits since the previous version tag. Set `MODRINTH_CHANGELOG` to override it with curated notes.
+
+
+## Configuration
+
+`plugins/Metropolis/config.yml` controls plot dimensions and limits, floor and support generation, signs, road width/level/material/clearance, spawn behavior, wall generation, world name, and per-player overrides. `plot.multiplier` sets the default plot-size multiplier; `plot.maxPerPlayer` sets the default home limit.
+
+Use `permissionOverrides` to assign plot size and home limits through any permission manager. Each permission node maps to a `priority`, `plotMultiplier`, and `maxPlots`; the matching node with the highest priority wins, and the last matching entry in YAML order wins ties. An explicit username entry in `userOverrides` takes precedence over permission rules. If no override matches, the global `plot.*` defaults apply. Permission rules are checked for online players; offline home generation uses username overrides or global defaults. For example:
+
+```yaml
+permissionOverrides:
+	metropolis.plots.vip:
+		priority: 10
+		plotMultiplier: 2
+		maxPlots: 2

+
+Assign these permission nodes to groups or individual users in your permission plugin. Bukkit permissions are boolean, so the configured values determine the numeric limits. The bundled configuration provides the defaults. Metropolis targets Paper 26.2 and 26.3 only; Bukkit and Spigot servers are not supported.

+## Commands
+
+| Command | Permission | Description |
+| --- | --- | --- |
+| `/metropolis` | None | Displays the plugin version. |
+| `/metropolis-home-acquire` | Player only | Acquires an available home if the player's home limit is not reached. |
+| `/metropolis-home-generate <playerName>` | `metropolis.home.generate` | Generates a home for an online or cached offline player. |
+| `/metropolis-home-list` | `metropolis.home.list` | Lists the occupied and reserved Metropolis plots with their bounds. |
+| `/metropolis-home-go [playerName]` | `metropolis.home.go` | Teleports the sender, or a permitted target player, to their home. |
+| `/metropolis-home-move <homeNumber> [playerName]` | `metropolis.home.move` | Selects one of a player's existing homes as active. The player argument defaults to the sender; console and authorized admins can target online or cached offline players. The selection persists across restarts. |
+| `/metropolis-home-evict <playerName>` | `metropolis.home.evict` | Removes the player's ownership from their selected home region. |
+| `/metropolis-plot-reserve <name> <minX> <minY> <minZ> <maxX> <maxY> <maxZ>` | `metropolis.plot.reserve` | Creates a named reservation from explicit bounds. A player can instead run `/metropolis-plot-reserve <name>` with a WorldEdit selection. |
+| `/metropolis-plot-go <plotName> [playerName]` | `metropolis.plot.go` | Teleports the sender or target player to a named occupied or reserved plot. |
+| `/metropolis-flag-reset` | `metropolis.flag.reset` | Reapplies Metropolis protection flags to the City and home regions. |
+| `/metropolis-debug-generatetesthomes <count>` | `metropolis.debug` | Generates test homes; intended for development servers. |

+# Modernize Metropolis Plugin: Implementation Tasks
+
+|   ID    |  Status  | Title |
+|:-------:|:--------:|:------|
+| MET-001 |   Done   | Initialize Gradle in the project root, add the Gradle wrapper, and create the project build file. |
+| MET-002 |   Done   | Set Gradle project metadata and configure a Java toolchain compatible with the target modern Paper version. |
+| MET-003 |   Done   | Configure repositories and compatible PaperMC, WorldEdit, WorldGuard, and other required or optional dependencies; add build plugins such as Shadow only if needed. |
+| MET-004 |   Done   | Move or verify plugin.yml under src/main/resources, configure Gradle resource processing, and update its Paper api-version, dependencies, commands, permissions, and required fields. |
+| MET-005 |   Done   | Add JUnit 5 test infrastructure and keep the default Gradle `test` task server-free. Use an in-memory Paper harness such as MockBukkit for Bukkit/Paper behavior and mocks or test doubles for WorldEdit, WorldGuard, and narrow API boundaries where appropriate. |
+| MET-006 |   Done   | Build the initial Gradle project and run its tests; resolve build setup issues before removing the existing Maven build. |
+| MET-007 |   Done   | Update .gitignore for Gradle and remove obsolete Maven and Eclipse project files after the Gradle build succeeds. |
+| MET-008 |   Done   | Analyze Java sources for deprecated or removed Bukkit/Paper APIs and legacy patterns, including logging, event registration, configuration, player lookup, and player-keyed storage. |
+| MET-009 |   Done   | Review custom scripts and resources for required updates to the Gradle build and modern Paper server workflow. |
+| MET-010 |   Done   | Refactor plugin logging to use JavaPlugin.getLogger(). |
+| MET-011 |   Done   | Refactor event listeners and registration to use Listener, @EventHandler, and the modern plugin manager API. |
+| MET-012 |   Done   | Replace deprecated configuration APIs with the modern Bukkit/Paper configuration API, including load, save, and reload behavior. |
+| MET-013 |   Done   | Replace Player-keyed storage with UUID-based storage wherever player identity is persisted or tracked. |
+| MET-014 |   Done   | Review player lookup logic and use exact or otherwise explicit name-matching behavior where appropriate. |
+| MET-015 |   Done   | Refactor remaining code that uses deprecated or removed Bukkit, Spigot, or Paper APIs so it is compatible with the target Paper API. |
+| MET-016 |   Done   | Add fast unit tests for plot and home allocation, reservation validation, player lookup and UUID-based ownership, configuration persistence, command validation, and event behavior. Keep domain rules independent of a running Minecraft server and mock external plugin boundaries as needed. |
+| MET-017 |   Done   | Add a separate Gradle `integrationTest` source set/task for tests requiring an actual Paper server and compatible WorldGuard/WorldEdit plugins. Verify plugin loading, command registration and dispatch, region-backed reservations and home allocation, and persistence across a server restart. Run it only when explicitly requested; keep it out of the normal `test` and `build` tasks. |
+| MET-018 |   Done   | Build the plugin with Gradle and use the provided server scripts to smoke-test it on modern Paper with its required plugins installed. |
+| MET-019 |   Done   | Address bugs and incompatibilities found by unit tests, integration tests, or modern Paper server testing. |
+| MET-020 |   Done   | Adopt the git-sensitive semantic versioning Gradle plugin used by MobScores and ScoreKeeper, using the existing 0.5-SNAPSHOT version as the migration baseline; verify version/tag behavior and enable the Gradle configuration cache when compatible. |
+| MET-021 |   Done   | Update README.md, CONTRIBUTING.md, other documentation, and project scripts with the Gradle build, test, versioning, and modern Paper server workflow. |
+| MET-022 | Planning | (Optional) Add new features, quality-of-life improvements, or CI configuration after the modernization and documentation tasks are complete. |
+| MET-023 | Planning | Add an optional home-allocation policy that grants all remaining homes up to a player's limit when they join. |
+| MET-024 | Planning | Add an optional home-allocation policy that grants at most one additional home per login until the player's limit is reached. |
+| MET-025 | Planning | Add a configuration option to choose the plot-allocation traversal algorithm: concentric rectangles/cuboids or concentric rings that prefer a free location near the center. |
+| MET-026 | Planning | Research a world-conversion option for existing Metropolis worlds, including how to safely adapt existing regions and generated roads/plots. |
+| GIT-009 | Planning | i have three reserve plots and one just got overwritten when a new player joined. |
+| GIT-008 |   Ready  | Implement multiple plot sizes by granting multiple plots around each other. 
+| GIT-007 | Planning | Allow buying and selling of homes via an ecnoomy plugin. |
+| GIT-006 |   Ready  | Add levels support. |
+| GIT-005 | Planning | Add the possibility to create multiple plot homes in shapes. |

+# GIT-001 - Add a command to move to a different home.
+**Status:** Done
+**Depends On:** [GIT-003](#git-003---add-support-for-multiple-homes)
+**Description:**
+
+`/metropolis-home-move <homeNumber> [playerName]` selects one of a player's existing homes as active. Without a player name, the command acts on the player who ran it; console and authorized administrators can specify an online or cached offline player. Reject non-positive or malformed numbers, unknown players, nonexistent homes, and extra arguments with clear feedback. Persist the selection by player UUID and confirm the change to the sender and, when online, the target player.
+
+# GIT-002 - Add a command to teleport to a reservation you are part of.
+**Status:** Ready
+**Depends On:** [GIT-003](#git-003---add-support-for-multiple-homes)
+**Description:**

+
+### Comments
+
+Or better yet just use uhome or create your own, integrated that records the home location at the height set in the configuration file, but on the road next to the plot. Using existing plugins to insert into SQL say uhome, would allow privatization and minimal work on your end.
+
+# GIT-003 - Add support for multiple homes
+
+**Status:** Done
+**Description:**
+
+Add a top-level `permissionOverrides` map keyed by permission node. Each rule defines `priority`, `plotMultiplier`, and `maxPlots`; any permission manager can grant the boolean nodes to groups or individual players. For online players, the matching rule with the highest priority wins, with the last matching entry in YAML order breaking ties. An explicit `userOverrides` entry takes precedence over permission rules. Without either override, use `plot.multiplier` and `plot.maxPerPlayer`. Offline-player generation uses username overrides or global defaults because permissions are only queried for online players.
+
+On join, automatically allocate one home only when the player has no existing home, and restore a valid existing home as active if the saved selection is missing. Additional homes must be explicitly requested with `/metropolis-home-acquire`, up to the player's effective limit. Acquisition allocates the first unused positive home number and makes the new home active.
+
+The alternative login allocation policies are tracked separately in MET-023 and MET-024; they are not part of the default policy in this task.
+
+# GIT-004 - Add a command to request home allocation.
+**Status:** Ready
+**Depends On:** [GIT-003](#git-003---add-support-for-multiple-homes)
+**Description:**
+
+Add a command that users can type to get their first or subsequent homes.
+Add a config option to not generate any homes automatically, but to require this command to generate a user's first home.
+
+This could be used so that homes won't be generated until a user has read the server rules which would include telling them to type the command towards the end.
+
+# GIT-005 - Add the possibility to create multiple plot homes in shapes.
+**Status:** Planning
+**Description:**
+
+Add the possibility to create multiple plot homes in shapes
+
+
+# GIT-006 - Add levels support.
+**Status:** Ready
+**Description:**
+
+Add multiple vertical levels to the city. Use the existing `road.level` as the base Y: the bottom of a ground-level plot is at that Y, and `plot.sizeY` defines the full plot height. For example, a five-block-high plot includes its floor at road level, three usable blocks, and a roof block; all five blocks belong to the plot region. Use the same plot-dimension-plus-road-spacing grid pitch vertically as horizontally; when road width is zero, adjacent plot volumes may touch. Do not allocate a plot if its full extent would exceed the world's buildable area. If the search cannot find any valid plot, log an allocation error and do not create the plot or region. The current config example is not intended for a multilevel world; request an updated `config.yml` before implementation. Existing `plot.offsetX`, `plot.offsetY`, and `plot.offsetZ` nudge the grid; `plot.multiplier`, `userOverrides[username].plotMultiplier`, and future `permissionOverrides[permission_name].plotMultiplier` affect plot size.
+
+Add a maximum-level config value. If unset, default to 1; administrators can increase it to enable more levels. Allocate plots in X, Z, Y axis order: scan X from negative to positive, then increment Z, and only after scanning the X/Z area increment Y to the next level (Y outermost, Z middle, X innermost). For equal-distance candidates, use the same negative-to-positive X ordering. The selectable X/Z traversal shapes are tracked separately in MET-025.
+
+Streets run along X and avenues run along Z. Streets remain level; avenues connect levels with stairs placed beside plots at a configurable cadence. Add `stairs.*`, `road.streets.*`, and `road.avenues.*` configuration. The street and avenue sections should each contain the current `road.*` settings plus `generateStairs`. Configure stair material, width, and `everyNBlocks`; this cadence is measured in plot-sized avenue blocks, so 3 means stairs beside every third plot along an avenue. Allow stairs to be configured independently for each direction, including different widths. Validate each enabled direction against its corresponding road width; if its stairs are not thinner than that road, log an error but continue plugin startup.
+
+Keep spawn on its current level. Add independent X, Y, and Z spawn-size multipliers, each expressed as a multiple of the corresponding plot dimension and road spacing so roads line up with differently sized plots. The Y multiplier controls spawn's vertical height upward from `road.level`.
+
+When allocating plots in an existing world, treat saved WorldGuard regions as occupied: never overwrite a region or create a new region that overlaps an existing one, even if avoiding overlaps leaves irregular gaps between plots and roads. Document this behavior so users know to expect it. Research a possible world-conversion option separately under MET-026; conversion requires further investigation.
+
+This intentionally breaks the existing config schema: do not add a legacy `road.*` fallback or automatic migration. Document the config changes in release notes and make the breaking change in the 0.6.x release line.
+
+# GIT-007 - Allow buying and selling of homes via an ecnoomy plugin.
+**Status:** Blocked
+**Blockers:** Figure out how to integrate with economy plugins.
+**Description:**
+
+Allow buying and selling of homes via an ecnoomy plugin. Include decent real estate support including wtb and wts listings as well as an auction facility.
+
+This should also support not giving free plots to users with none. This way one would have to go out and mine to earn money which could be spent to purchase a plot.
+
+# GIT-008 - Implement multiple plot sizes by granting multiple plots around each other.
+**Status:** Ready
+**Description:**
+
+a= user a
+x= empty plot
+s= spawn
+
+user a get's a small plot which is defined as 1 plot
+a x x
+x s x
+x x x
+
+user b gets a large plot which is defined as 4 plots

-Goal: Have 1 plot size for mods and 1 plot size for normals.
-Implementation:
-	1.	Set the plotSize in the config to the larger plot size there are other possible sizes but powers of 2 work really well so lets give mods a 64x64 plot.  Roads are recomended but will eat into the plot on all sides so the roadsize can be ignored for this example.
-	2.	Start the server and run /metropolis-home-generate <username> for each mod.
-	3.	If you have not completed a full ring then run /metropolis-home-generate <test n> where n starts at 1 and increases until you have filled a full ring.  This will reserve those plots for later or anyone who happens to have that username, but that can be dealth with later.
-	4.  Stop the server and change the plotSize to a smaller number like 32.
-	5.	Restart the server and let your users log in.
-	
-Notes:
-	All users will be assigned a small plot when they first connect.  When you make them a mod just delete their current region and change the name of one of the reserved home regions to h_<their username>.
-	/region remove h_jonnynewadmin
-	/region select test_1
-	/region remove test_1
-	/region define h_johnnynewadmin
-	JohnnyNewAdmin's old home will become available for resettlement.  If you want to copy johnny's old blocks into his new home region I'd suggest WorldEdit.
-	This process including optionally copying the blocks will be an upcoming feature.  Probably in 0.5.x and maybe in 0.6.
-	
-	If you later run out of larger plots you can just set the size back to the larger number and let more generate.  Moving and evictions will be coming soon and make this easier.
-	You can manually just create a region for a user before they login named like h_<username> if you want a specific user to have a really big space as well.
