release: bump 0.8.8 -> 0.8.9 (#285 )

Maintenance release — supply-chain and CI housekeeping only. No library code or public API changes. ### Security - Triaged the pyo3 advisories RUSTSEC-2026-0176 / RUSTSEC-2026-0177 as not affecting Wickra (vulnerable APIs unreachable from the binding; fix blocked upstream by rust-numpy pinning pyo3 `^0.28`). Recorded in `deny.toml` and `osv-scanner.toml`. ### Changed - Java binding: `central-publishing-maven-plugin` 0.5.0 → 0.10.0. - CI GitHub Actions bumped to latest (checkout, setup-go, setup-java, codeql-action, taiki-e/install-action). - Added a Maven ecosystem to Dependabot. Version bumped across all manifests/lockfiles via `bump_version.py`; Cargo.lock refreshed. CHANGELOG `[0.8.9]` filled. Tag/publish to follow on explicit GO.
chore(supply-chain): osv-scanner suppressions, bump publishing plugin, track Maven in Dependabot (#272 )

+series through three indicators chosen by call-signature archetype — `SMA(20)`
+(1-in → 1-out), `ATR(14)` (multi-in → 1-out) and `MACD(12,26,9)` (1-in →
+multi-out). Two things fall out of the numbers:
+
+- **Batch converges.** A `batch` call crosses the boundary once and the Rust core
+  computes the whole series internally, so batch throughput is roughly the same
+  in every binding — close to the core speed.
+- **Streaming reveals the boundary.** A per-tick `update` crosses the boundary
+  once per value, so streaming throughput is where the bindings differ: the raw C
+  ABI and P/Invoke-style calls are nearly free, while managed or interpreted
+  per-call marshalling (cgo, FFM, the R/WASM boundary) costs more per tick.
+
+The Rust core ships the same benchmark with **no** FFI boundary
+(`examples/rust/.../throughput.rs`) — it is the ceiling each binding is measured
+against and the value the batch paths converge towards.
+
+`SMA(20)`, 200 000 bars, median of 3 runs, on the reference machine (Windows 11,
+AMD Ryzen 9 9950X):

+| Target               | streaming (Mupd/s) | batch (Mupd/s) |

+| Rust core (no FFI)   |                391 |            500 |

+| Node.js              |                 17 |             10 |
+| R                    |                0.1 |            193 |
+
+Streaming spans more than three orders of magnitude — the raw C ABI (383) is
+nearly the FFI-free Rust ceiling (391), while R's per-call interpreter overhead
+(0.1) makes streaming ~2000× slower than its own batch. Batch converges near the
+core speed for the zero-copy bindings (numpy, slices, typed arrays); the two
+outliers are Node — whose napi `batch` boxes every element into a JS `Array` —
+and R. These are machine-dependent and reflect FFI overhead, not algorithm
+speed.
+
+These are throughput numbers, not competitive numbers — the "Wickra is fast"
+claim lives in sections 1 and 2 (Rust core + the Python/Rust cross-library runs).
+
+Run any target's benchmark (build the C ABI library first where it links one):
+
+```bash
+cargo run -p wickra-examples --release --bin throughput           # Rust core baseline (no FFI)

 ## [Unreleased]

+## [0.8.9] - 2026-06-12
+
+Maintenance release: supply-chain and CI housekeeping only. No library code or
+public API changes.
+
+### Security
+- Triaged the pyo3 advisories RUSTSEC-2026-0176 (out-of-bounds read in
+  `PyList`/`PyTuple` `nth`/`nth_back`) and RUSTSEC-2026-0177 (missing `Sync`
+  bound on `PyCFunction::new_closure`) as **not affecting Wickra**: neither
+  vulnerable API is reachable from the Python binding. Both are fixed in pyo3
+  0.29, but rust-numpy 0.28 pins pyo3 `^0.28`, so the upgrade is blocked
+  upstream; the advisories are recorded with their not-affected rationale in
+  `deny.toml` and `osv-scanner.toml` and will be cleared once rust-numpy 0.29
+  ships.
+
+### Changed
+- Java binding: bumped `central-publishing-maven-plugin` 0.5.0 → 0.10.0 (the
+  Maven Central publishing plugin used at release time).
+- Bumped the SHA-pinned GitHub Actions used in CI (`actions/checkout`,
+  `actions/setup-go`, `actions/setup-java`, `github/codeql-action`,
+  `taiki-e/install-action`) to their latest releases.
+- Added a Maven ecosystem to Dependabot so the Java binding's build plugins and
+  dependencies are tracked going forward.
+
+
+## [0.8.8] - 2026-06-11
+### Fixed
+- R binding: declare `Depends: R (>= 2.10)`, clearing the `R CMD check` warning
+  ("package needs dependence on R (>= 2.10)") that the bundled, lazy-loaded
+  `sample_ohlcv` dataset triggers on r-universe / CRAN.
+
+## [0.8.7] - 2026-06-11
+### Added
+- R binding: a *Getting started* vignette and a synthetic `sample_ohlcv` example
+  dataset, giving new users a runnable, self-contained walkthrough and populating
+  the R-universe Articles and Datasets tabs. The vignette's code is exercised in
+  CI so a broken example is caught before the published build.
+
+## [0.8.6] - 2026-06-11
+### Changed
+- Package registry metadata for better discoverability:
+  - R (R-universe): added the R-universe URL and `X-schema.org-keywords` to the
+    R `DESCRIPTION`, plus a package logo at `bindings/r/man/figures/logo.png`
+    (pkgdown convention).
+  - Python (PyPI): added a `Documentation` project URL.
+  - C# (NuGet): added a package icon via `PackageIcon`.
+
+## [0.8.5] - 2026-06-11
+### Fixed
+- The R binding's golden-fixture parity test now skips gracefully when the shared
+  `testdata/golden` fixtures are not bundled with the package — standalone
+  r-universe / CRAN builds package only `bindings/r`, so the repo-root fixtures
+  are unreachable there. The parity stays enforced by the repository CI, where
+  the fixtures are present.
+
+## [0.8.4] - 2026-06-11
+### Fixed
+- A single non-finite (NaN/inf) tick no longer poisons indicator state.
+  The 16 pairwise running-sum/buffer indicators fixed first (`Beta`,
+  `BetaNeutralSpread`, `Cointegration`, `HasbrouckInformationShare`,
+  `PearsonCorrelation`, `RollingCorrelation`, `RollingCovariance`,
+  `DistanceSsd`, `GrangerCausality`, `KendallTau`, `LeadLagCrossCorrelation`,
+  `OuHalfLife`, `SpearmanCorrelation`, `SpreadAr1Coefficient`, `SpreadHurst`,
+  `VarianceRatio`) were joined by 38 more scalar/pairwise indicators the new
+  property harness surfaced (the linear-regression family, rolling quantiles
+  and IQR, `Variance`/`StdDev`-derived stats, `Kurtosis`/`Skewness`, the
+  trailing stops, `KalmanHedgeRatio`, `SpreadBollingerBands`, and more). Every
+  `f64` / `(f64, f64)` indicator now rejects non-finite input and returns
+  `None`, matching the streaming-robustness guarantee — and the harness enforces
+  it going forward.
+
+### Added
+- Catalogue-wide property-based invariant harness
+  (`crates/wickra-core/tests/invariants.rs`) asserting `batch == streaming`,
+  `reset == fresh`, and non-finite-input rejection for every indicator and
+  bar-builder.
+
+### Changed
+- CI: every job now has a runtime cap and the historically flaky Node test step
+  auto-retries, so a wedged runner fails fast instead of hanging for hours.
+- Documentation accuracy fixes in `SECURITY.md`, `ARCHITECTURE.md`, and
+  `THREAT_MODEL.md` (supported version, indicator count, WASM test coverage,
+  numerical-stability notes, and the C-ABI panic strategy).
+
+## [0.8.3] - 2026-06-10
+### Added
+- **Per-binding throughput benchmarks** — every target now ships a `throughput`
+  benchmark mirroring the Node `throughput.js`: streaming and batch
+  updates-per-second for `SMA(20)`, `ATR(14)` and `MACD(12,26,9)` over a
+  synthetic OHLCV series. New for Python (`bindings/python/benchmarks/`), C
+  (`bindings/c/benchmarks/`), C# (`bindings/csharp/benchmarks/`), Go
+  (`bindings/go/benchmarks/`), Java (`bindings/java/benchmarks/`), R
+  (`bindings/r/benchmarks/`), WebAssembly (`bindings/wasm/benchmarks/`) and the
+  Rust core baseline (`examples/rust/.../throughput.rs`, no FFI). They measure
+  each binding's FFI overhead — the same Rust core runs underneath all of them —
+  and are documented in [BENCHMARKS.md](BENCHMARKS.md) §3, not a cross-library
+  speed claim.
+- **C ABI archetype test** — `examples/c/archetypes.c` exercises one indicator
+  per FFI archetype (scalar, multi-output, bars, profile, array input) through
+  the C boundary, matching the Go/R/Java suites.
+
+## [0.8.2] - 2026-06-10
+### Fixed
+- **R binding builds for WebAssembly** — `bindings/r/configure` now builds the
+  C ABI from source for the `wasm32-unknown-emscripten` target (r-universe /
+  webR) using the build image's cargo + emscripten, instead of failing with
+  "unsupported OS Emscripten". rayon is dropped on wasm via
+  `--no-default-features`; the indicators are pure computation, so the serial
+  path is functionally identical.
+
+## [0.8.1] - 2026-06-10
+### Fixed
+- **`wickra-go` license** — the release-time Go module mirror now ships the dual
+  `LICENSE-MIT` and `LICENSE-APACHE` files, so pkg.go.dev detects a
+  redistributable license for `github.com/wickra-lib/wickra-go`. The previous
+  mirror shipped no license file.
+
+## [0.8.0] - 2026-06-09
+### Added
+- **Standalone `wickra-go` module** — the Go binding is now mirrored to a
+  dedicated `github.com/wickra-lib/wickra-go` repository on every release, with
+  the prebuilt C ABI libraries committed per platform under
+  `lib/<goos>_<goarch>/` and the C ABI header vendored alongside the source, so
+  `go get github.com/wickra-lib/wickra-go` builds with no extra steps. The
+  in-repo `bindings/go` module is unchanged for repo-clone workflows.
+
+### Changed
+- **Go binding (`bindings/go`) is self-contained** — the C ABI header is now
+  vendored inside the module (`bindings/go/include/wickra.h`) instead of being
+  referenced from the parent `bindings/c` directory, and the cgo link flags
+  resolve the prebuilt library per `GOOS`/`GOARCH` under `lib/<goos>_<goarch>/`.
+  This removes the dependency on a full repository checkout for building the
+  module.
+
+## [0.7.9] - 2026-06-09
+### Added
+- **Java binding (`bindings/java`)** — a Java binding reaching the C ABI hub
+  through the Java Foreign Function & Memory API (Panama, `java.lang.foreign`,
+  final in Java 22) rather than JNI or jextract, exposing all 514 indicators as
+  idiomatic `AutoCloseable` classes. The downcall handles, per-indicator
+  wrappers and output records are generated from `wickra.h`; the opaque handle is
+  a `MemorySegment` freed by a `java.lang.ref.Cleaner` action. Ships a full
+  example suite mirroring the C, C#, Go and R examples; published to Maven
+  Central as `org.wickra:wickra`.
+
+## [0.7.8] - 2026-06-09
+### Added
+- **R binding (`bindings/r`)** — an R package reaching the C ABI hub through R's
+  native `.Call` interface, exposing all 514 indicators as constructors that
+  return a `wickra_indicator` object with `update`/`batch`/`reset` methods. The
+  C glue and R wrappers are generated from `wickra.h`; the native handle is freed
+  by a registered finalizer. Ships a full example suite mirroring the C, C# and
+  Go examples; distributed for r-universe / source install.

 ## Install

+Use the published **`wickra-go`** module, which bundles the prebuilt C ABI
+library for every platform, so `go get` + `go build` works with no extra steps
+(a C compiler is still required, as the binding uses cgo):
+
 ```bash
-go get github.com/wickra-lib/wickra/bindings/go
+go get github.com/wickra-lib/wickra-go

+in via rpath; on Windows the DLL must be discoverable at run time (next to the
+executable or on `PATH`).

+
+**Streaming-first technical indicators for the JVM, on the Java Foreign Function
+& Memory API — prebuilt native library, no JNI, no system dependencies.**
+
+Wickra is a multi-language technical-analysis library with a Rust core and
+bindings for Python, Node.js and WebAssembly, plus a C ABI for C/C++, C#, Go, Java, R
+and any other C-capable language. Every indicator is an O(1) streaming state
+machine, so live trading bots and historical backtests share the exact same
+implementation. This package is the Java binding; it consumes the C ABI hub
+through the Panama FFM API (`java.lang.foreign`) and exposes all 514
+streaming-first indicators as idiomatic `AutoCloseable` classes.
+
+## Requirements
+
+- **Java 22 or later** (the FFM API is final since Java 22; no preview flag).
+- The FFM API is *restricted*: pass `--enable-native-access=ALL-UNNAMED` when you
+  run your application to silence the native-access warning.
+
+## Install
+
+Maven:
+
+```xml
+<dependency>
+  <groupId>org.wickra</groupId>
+  <artifactId>wickra</artifactId>
+  <version>0.8.9</version>
+</dependency>
+```
+
+Gradle:
+
+```kotlin
+implementation("org.wickra:wickra:0.8.9")
+```
+
+The native library ships prebuilt per platform (Linux, macOS, Windows — x64 and
+arm64) inside the jar and is extracted automatically on first use. There is
+nothing to compile.
+
+## Quick start
+
+```java
+import org.wickra.Ema;
+import org.wickra.Rsi;
+
+// Batch: run an indicator over a whole series (NaN at warmup positions).
+double[] prices = new double[1000];
+for (int i = 0; i < prices.length; i++) {
+    prices[i] = 100.0 + i * 0.1;
+}
+try (Ema ema = new Ema(20)) {
+    double[] values = ema.batch(prices);
+}
+
+// Streaming: the same indicator, fed tick by tick in O(1).
+try (Rsi rsi = new Rsi(14)) {
+    for (double price : liveFeed) {
+        double value = rsi.update(price); // NaN during warmup, no recomputation
+        if (Double.isFinite(value) && value > 70) {
+            System.out.println("overbought");
+        }
+    }
+}
+```
+
+`batch(prices)` and feeding the same prices through `update()` produce identical
+values — the equivalence is enforced by the test suite. Multi-output indicators
+(MACD, Bollinger, ADX, …) return a `record`, `null` while warming up. Each
+indicator owns a native handle freed by a `Cleaner`; `close()` releases it
+eagerly (use try-with-resources).
+
+## Benchmark
+
+`benchmarks/` reports streaming and batch updates-per-second for `SMA`, `ATR`
+and `MACD`. It measures this binding's FFI overhead, not a cross-library ratio
+(the same Rust core runs under every binding) — see the repository
+[BENCHMARKS.md](https://github.com/wickra-lib/wickra/blob/main/BENCHMARKS.md) §3.
+
+```bash
+cargo build -p wickra-c --release
+mvn -q install -DskipTests
+mvn -q -f benchmarks exec:exec -Dexec.mainClass=org.wickra.benchmarks.Throughput
+```
+
+## Documentation
+
+The full indicator catalogue, guides, quickstarts, and API reference live in
+the main repository and documentation site:
+
+- **Repository & full indicator list:** <https://github.com/wickra-lib/wickra>
+- **Docs** (quickstarts, cookbook, TA-Lib migration): <https://docs.wickra.org>
+- **Runnable examples:** [`examples/java/`](https://github.com/wickra-lib/wickra/tree/main/examples/java)
+
+Wickra ships native bindings for Python, Node.js, WebAssembly and Rust, plus a
+C ABI hub that any C-capable language (C, C++, Go, C#, Java, R) links against —
+all exposing the same indicators from the shared, `unsafe`-forbidden Rust core.
+
+## Disclaimer
+
+Wickra is an indicator toolkit, not a trading system. The values it computes
+are deterministic transforms of the input data — they are not financial advice
+and do not predict the market. Any use in a live trading context is at your own
+risk. The library is provided **as is**, without warranty of any kind.

+/**
+ * Throughput benchmark for the Wickra Java binding.
+ *
+ * <p>Measures how many indicator updates per second the binding sustains, both
+ * per-tick (streaming {@code update}) and bulk ({@code batch}), over a synthetic
+ * OHLCV series. It is the Java counterpart of the Node {@code throughput.js} and
+ * the Rust criterion benches: it benchmarks Wickra's own O(1) streaming engine
+ * across the Java FFM &lt;-&gt; C-ABI boundary (there is no comparable streaming
+ * TA library on Maven Central to compare against), so the headline number is raw
+ * per-binding throughput / FFI overhead, not a cross-library ratio.
+ *
+ * <p>Three indicators are timed, chosen by FFI call-signature archetype rather
+ * than algorithm: SMA (1-in -&gt; 1-out), ATR (multi-in -&gt; 1-out), and MACD
+ * (1-in -&gt; multi-out). Streaming is timed for all three; batch only for the
+ * single-output SMA and ATR (multi-output batch is not exposed uniformly).
+ *
+ * <p>Install the binding and build the C ABI library first, then run from the
+ * repo root:
+ *
