+# Rust API and C# migration guide
+
+`MetaCrate` is a native Rust implementation of the API and behavior cataloged
+from `LibreMetaverse`. The compatibility reference is the
+[pinned C# source](https://github.com/cinderblocks/libremetaverse/tree/2aa70bb68513b39795da5d13c88f31b86e85a3ba);
+it is never loaded, invoked, or shipped. Exact type/member mappings live in
+[`RUST-TYPES.tsv`](../api/RUST-TYPES.tsv) and
+[`RUST-MAPPING.tsv`](../api/RUST-MAPPING.tsv). Search those files by C#
+documentation ID when a familiar member has a non-obvious Rust name.
+
+## Choosing crates and features
+
+Most applications start with `libremetaverse` and add narrower crates only when
+they use those APIs directly.
+
+| Crate | Choose it for | Features or system boundary |
+| --- | --- | --- |
+| `libremetaverse` | Grid client, login, network, agents, inventory, assets, appearance, world, and social APIs | Default pure-Rust BC6H/BC7; optional `jpeg2000` and `vorbis` |
+| `libremetaverse-types` | UUIDs, vectors, matrices, colors, cancellation, compatibility collections, and boundary types | Pure Rust |
+| `libremetaverse-structured-data` | LLSD/OSD XML, JSON, binary, and notation | Pure Rust |
+| `libremetaverse-imaging` | Managed images, TGA/DDS, codec traits | Optional `jpeg2000` |
+| `libremetaverse-imaging-skia` | Common raster formats through Skia | Optional `skia`; native Skia build/cache |
+| `libremetaverse-prim-mesher` | Legacy prim and sculpt geometry | Pure Rust |
+| `libremetaverse-rendering-simple` | Deterministic reference geometry | Pure Rust |
+| `libremetaverse-rendering-mesh-foundry` | Prim, terrain, sculpt, and mesh-asset rendering | Pure Rust |
+| `libremetaverse-lsl-tools` | LSL lexing, parsing, diagnostics, and generation | Pure Rust |
+| `libremetaverse-rlv` | RLV commands, restrictions, locks, camera, and inventory policy | Pure Rust |
+| `libremetaverse-utilities` | Compatible utility helpers | Pure Rust |
+| `libremetaverse-voice-vivox` | Vivox XML control protocol | External Vivox service is explicit and never spawned |
+| `libremetaverse-voice-webrtc` | Native ICE/DTLS/SRTP/SCTP and Opus voice | System libopus; optional `real-audio` uses CPAL |
+| `libremetaverse-openjpeg` | Audited `OpenJPEG` adapter | System `OpenJPEG` 2.5.4 or newer |
+| `libremetaverse-opus` | Audited Opus encoder/decoder adapter | System libopus |
+
+Features are additive. Keep defaults unless you need a codec, and enable one
+native adapter at a time while diagnosing installation problems. The
+[release CI matrix](release-ci-matrix.md) records every validated combination.
+
+## Naming and overload migration
+
+C# `PascalCase` types remain recognizable while methods and properties use
+Rust `snake_case`. A property getter becomes `name()` and its setter becomes
+`set_name(value)`. Events become `subscribe_*` methods returning an owned
+subscription. Rust has no overloads, so the simplest form keeps the base name
+and additional forms receive parameter-derived suffixes. The mapping ledger is
+authoritative; do not guess a long suffix.
+
+```rust
+use libremetaverse::InventoryItem;
+use libremetaverse_types::UUID;
+
+let id = UUID::new_with_u_int64(42)?;
+let mut item = InventoryItem::new_with_uuid(id)?;
+item.base.set_name("Migrated item".into());
+assert_eq!(item.base.uuid(), id);
+assert_eq!(item.base.name(), "Migrated item");
+# Ok::<(), libremetaverse::Error>(())
+```
+
+C# `null` usually maps to `Option<T>`, `ref`/`out` may become a return value or
+an explicit mutable reference, and interface objects become `dyn Trait` behind
+`Arc` or `Box` according to the ledger's `ownership` column.
+
+## Ownership and disposal
+
+Managers cloned from a `GridClient` share native state. `GridClient` owns its
+cancellation root and cached services; event guards own registrations; session
+objects own tasks and sockets. Explicit shutdown is recommended because it can
+report errors, while `Drop` remains the final idempotent safety net.
+
+```rust
+use libremetaverse::{ClientLifecycleState, GridClient};
+
+let client = GridClient::new()?;
+assert_eq!(client.lifecycle_state(), ClientLifecycleState::Active);
+client.dispose_with_method()?;
+client.dispose_with_method()?; // idempotent
+assert_eq!(client.lifecycle_state(), ClientLifecycleState::Disposed);
+# Ok::<(), libremetaverse::Error>(())
+```
+
+The runnable version is
+[`offline_client.rs`](../crates/libremetaverse/examples/offline_client.rs).
+Never hold a manager lock while calling user code or awaiting I/O. Services
+registered through `GridClient::builder()` must join every owned task before
+their `shutdown` method returns.
+
+## Async work and cancellation
+
+Async APIs borrow no hidden runtime. Call them from the application executor and
+pass `CancellationToken` explicitly where the C# API accepted one. Cloning a
+token is cheap and observes the same cancellation source. Cancellation is a
+typed `Error::Cancelled`, not a successful empty response.
+
+```rust
+use libremetaverse_types::compat::CancellationTokenSource;
+
+# #[tokio::main(flavor = "current_thread")]
+# async fn main() -> Result<(), libremetaverse::Error> {
+let source = CancellationTokenSource::new();
+let token = source.token();
+source.cancel();
+token.cancelled().await;
+assert!(matches!(
+    token.throw_if_cancellation_requested(),
+    Err(libremetaverse::Error::Cancelled)
+));
+# Ok(())
+# }
+```
+
+The same code is available as
+[`cancellation.rs`](../crates/libremetaverse/examples/cancellation.rs).
+Timeouts belong at the caller or documented operation boundary; cancellation
+must still drain and join the underlying resource owner.
+
+## Errors
+
+Fallible compatibility APIs return the shared `libremetaverse::Error`; native
+composition APIs may expose a narrower error such as `ClientCoreError` or
+`WebRtcError`. Match variants for control flow and use display text only for
+operators. Errors and `Debug` output redact credentials, capability URLs, and
+session secrets.
+
+```rust
+use libremetaverse::http::DownloadRequest;
+use libremetaverse_types::compat::Uri;
+
+let result = DownloadRequest::new(Uri("file:///not-http".into()), None, None);
+assert!(matches!(result, Err(libremetaverse::Error::Argument)));
+```
+
+Do not translate C# exception swallowing into `unwrap_or_default()`. Preserve
+the mapped error contract and handle cancellation separately from protocol,
+I/O, authentication, and validation failures.
+
+## Events and subscriptions
+
+An `EventHandler<T>` is an `Arc` callback. Keep the returned `Subscription` for
+exactly as long as notifications are wanted; dropping it unregisters the
+callback. Dispatch clones the handler list and releases internal locks before
+calling user code. Manager event dispatch isolates subscriber panics so one
+consumer cannot stop later consumers.
+
+```rust
+use libremetaverse::{GridClient, Inventory, InventoryFolder};
+use libremetaverse_types::UUID;
+use std::sync::Arc;
+use std::sync::atomic::{AtomicUsize, Ordering};
+
+let client = Arc::new(GridClient::new()?);
+let inventory = Inventory::new_with_grid_client_uuid(Arc::clone(&client), UUID::zero())?;
+let calls = Arc::new(AtomicUsize::new(0));
+let observed = Arc::clone(&calls);
+let subscription = inventory.subscribe_inventory_object_added(Arc::new(move |_| {
+    observed.fetch_add(1, Ordering::AcqRel);
+}));
+let folder = InventoryFolder::new(UUID::new_with_u_int64(7)?)?;
+inventory.update_node_for(&folder)?;
+assert_eq!(calls.load(Ordering::Acquire), 1);
+drop(subscription);
+client.dispose_with_method()?;
+# Ok::<(), libremetaverse::Error>(())
+```
+
+## Threading and callbacks
+
+Public shared managers use `Arc`, atomics, mutexes, channels, and cancellation
+tokens rather than a CLR synchronization context. A type being cloneable does
+not make a callback re-entrant: keep handlers short, move expensive work to a
+bounded queue, and never block an async runtime thread waiting for itself.
+Download, inventory, client, and voice diagnostics expose owned task/queue
+counts for shutdown checks. The [concurrency audit](concurrency-hardening.md)
+defines the exact baseline and soak thresholds.
+
+## Security boundaries
+
+The released graph contains no CLR host, .NET assembly loader, subprocess RPC,
+or foreign `LibreMetaverse` bridge. HTTP uses rustls. Untrusted LLSD, archive,
+image, packet, event, and signaling inputs have explicit size/depth limits.
+Secrets belong in operation arguments or environment variables, never in
+diagnostics, evidence, filenames, command lines, or committed fixtures.
+
+Offline/fake modes are real deterministic executions, not skipped live tests.
+Live login and every mutating smoke action require their own opt-in and literal
+confirmation. See the [live-grid boundary](live-grid-smoke.md).
+
+## Native prerequisites
+
+The default client build needs no image-codec system library. Optional native
+features require:
+
+- `OpenJPEG` 2.5.4 or newer for `jpeg2000`;
+- the rust-skia prerequisites/cache for `skia`;
+- system libopus for WebRTC voice and the `libremetaverse-opus` adapter;
+- ALSA development headers on Linux, `CoreAudio` on macOS, or WASAPI on Windows
+  when `real-audio` enables CPAL;
+- the Vorbis encoder build prerequisites for `vorbis`.
+
+Discovery uses `pkg-config` on Unix/macOS and `vcpkg` on Windows MSVC where
+applicable. The adapters remain cross-platform; Gitea workflows intentionally
+run only on `ubuntu-latest`.
+
+## Live `OpenSim` setup
+
+Use a dedicated `OpenSim` account and put credentials in the workspace `.env` or
+the process environment. The login URL is used directly; no Second Life host is
+substituted.
+
+```text
+GRID_USER=First Last
+GRID_PASSWORD=...
+GRID_LOGIN_URL=https://your-opensim.example/login
+```
+
+Start with the credential-safe audit and fake smoke, then opt into live login:
+
+```sh
+cargo run -p libremetaverse-programs --bin live-grid-smoke -- --audit-only
+cargo run -p libremetaverse-programs --bin live-grid-smoke -- --fake
+cargo run -p libremetaverse-programs --bin live-grid-smoke -- \
+  --allow-live-login --confirm-live-login LOGIN
+```
+
+Chat, movement, and reversible inventory each require additional confirmations
+documented in the [`OpenSim` live-grid guide](live-grid-smoke.md). A test that
+needs live credentials must fail clearly when they are absent; it must not
+silently skip.
+
+## Programs and operational tools
+
+All pinned upstream programs have native Rust targets and deterministic offline
+tests. Their arguments, exit statuses, fake/live boundaries, and focused test
+commands are linked from the [program operations manual](../programs/README.md):
+
+- [`osd-inspector`](../programs/README.md#osdinspector)
+- [`simple-bot`](../programs/README.md#simplebot)
+- [`packet-dump`](../programs/README.md#packetdump)
+- [`prim-inspector`](../programs/README.md#priminspector)
+- [`inventory-explorer`](../programs/README.md#inventoryexplorer)
+- [`irc-gateway`](../programs/README.md#ircgateway)
+- [`test-client`](../programs/README.md#testclient)
+- [`vivox-test`](../programs/README.md#vivoxtest)
+- [`webrtc-test`](../programs/README.md#webrtctest)
+
+For services, run the client under an external supervisor, propagate shutdown
+cancellation, bound queues/files, collect sanitized evidence, and call logout
+before disposal. The tool never invents persistence or retry policy on behalf of
+the application.
+
+## Documentation validation
+
+The complete documentation gate is:
+
+```sh
+cargo run --locked -p metacrate-ci-matrix -- documentation-audit \
+  --evidence /tmp/metacrate-documentation.json
+RUSTDOCFLAGS="-D warnings" cargo doc --workspace --no-deps --locked -j 1
+cargo test --locked -p libremetaverse --doc -j 1
+cargo test --locked -p libremetaverse --examples -j 1
+cargo run --locked -p libremetaverse --example offline_client
+cargo run --locked -p libremetaverse --example cancellation
+```
+
+The generated [coverage report](../api/DOCUMENTATION-COVERAGE.md) proves that
+every mapped member/type retains its exact C# concept ID and mapping context,
+all public crates have root docs, all local Markdown links resolve, all programs
+are linked, and every Rust fence in this guide is compiled as a doctest.
