+## 3. Per-binding throughput — the cost of the boundary
+
+The sections above compare Wickra against other libraries, which only exists for
+Python and Rust (there is no comparable streaming TA library for C, C++, C#, Go, Java,
+R or WASM to benchmark against). Every binding calls the **same** Rust
+core, so these per-binding benchmarks are **not** a speed claim and **not** a
+cross-library ratio — they document the raw cost of crossing each language's FFI
+boundary, in million updates per second (Mupd/s).
+
+Each binding ships a small `throughput` benchmark that feeds a synthetic OHLCV
+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.

+
+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).

+## [Unreleased]
+
+## [0.9.1] - 2026-06-14
+
+### Added
+- C ABI hub: every indicator now exposes `wickra_<ind>_warmup_period` and
+  `wickra_<ind>_is_ready`, closing the gap with the native bindings (which
+  already had them). The C-ABI languages surface them idiomatically: C# `int
+  WarmupPeriod()` / `bool IsReady()`, Go `WarmupPeriod()` / `IsReady()`, Java
+  `int warmupPeriod()` / `boolean isReady()`, and R `warmup_period()` /
+  `is_ready()` generics. The alt-chart bar builders are excluded by design (a
+  candle can complete 0..n bars, so they have no warmup).
+- Runnable rustdoc examples for 23 indicators that previously lacked one.
+- A Requirements reference documenting the minimum supported version per
+  language — a new page in the documentation site plus README, marketing-site
+  and organization-profile sections.
+
+### Changed
+- Raised the minimum Node.js version to 20 — Node 18 reached end-of-life. The
+  prebuilt N-API addon is now tested on the active LTS lines (22 and 24).
+- The Java binding now builds on the JDK 25 LTS in CI (JDK 22 reached
+  end-of-life); the published bytecode still targets Java 22, so the runtime
+  requirement is unchanged.
+- Standardised programming-language naming and ordering across all docs, READMEs,
+  the documentation site, marketing site, organization profile and GitHub
+  repository descriptions. Canonical list:
+  `Rust, Python, Node.js, WASM, C, C++, C#, Go, Java, R`. Uses C# (not .NET) as
+  the language label, lists C and C++ separately, prefers `Node.js` and `WASM` in
+  prose, and frames the C ABI as a hub (`C ABI hub → …`) rather than a
+  language-list entry. Documentation only — no code or public API changes.
+- Python binding: upgraded `pyo3` and `rust-numpy` from 0.28 to 0.29. No public
+  API changes; the full test suite passes unchanged.
+
+### Fixed
+- Corrected the internal casing of the `RelativeStrengthAB` binding wrappers,
+  which used `...Ab` (`WasmRelativeStrengthAb` in the WASM crate,
+  `RelativeStrengthAbNode` in the Node crate) while every other surface uses the
+  acronym `AB`. The published JS/WASM class name was already `RelativeStrengthAB`
+  (set via `js_name`/`js_class`), so the runtime API is unchanged; the only
+  visible change is the auto-generated TypeScript type alias, renamed
+  `RelativeStrengthAbNode` → `RelativeStrengthABNode` in `index.d.ts`.
+
+### Security
+- Resolved 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`) by upgrading to pyo3 0.29, which fixes
+  both. The upgrade was previously blocked upstream by rust-numpy 0.28 pinning
+  pyo3 `^0.28`; rust-numpy 0.29 lifts that pin. The not-affected exceptions are
+  removed from `deny.toml` and `osv-scanner.toml`.
+
+## [0.9.0] - 2026-06-13
+
+Maintenance release: Java build-dependency updates and CI/Dependabot
+housekeeping only. No library code or public API changes.
+
+### Changed
+- Java binding: upgraded the test framework to JUnit Jupiter 6.1.0 (from
+  5.10.2) and bumped the Maven build plugins — `maven-compiler-plugin`
+  3.13.0 → 3.15.0, `maven-surefire-plugin` 3.2.5 → 3.5.6, `maven-jar-plugin`
+  3.4.1 → 3.5.0, `maven-source-plugin` 3.3.1 → 3.4.0, `maven-javadoc-plugin`
+  3.7.0 → 3.12.0, and `maven-gpg-plugin` 3.2.4 → 3.2.8.
+- Java benchmarks and examples: bumped `maven-compiler-plugin` to 3.15.0 and
+  `exec-maven-plugin` to 3.6.3; examples bumped `jackson-databind` 2.17.1 →
+  2.22.0.
+- Grouped Dependabot updates per ecosystem into a single pull request and
+  extended tracking to the NuGet (C#) binding and the Node/Go examples.
+
+
+## [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.
+
