+name: Setup Rust toolchain (with retry)
+description: >
+  Install a Rust toolchain via dtolnay/rust-toolchain, retrying once after a
+  short pause on the transient rustup CDN failure (a corrupt channel manifest /
+  checksum mismatch on `channel-rust-<channel>.toml`) that rustup itself does
+  not retry — the same hardening already applied to setup-node / setup-go.

+Wickra ships its own data layer — a CSV candle reader, a tick-to-candle
+aggregator, and a timeframe resampler — so loading and reshaping market data
+needs **no third-party package** (`pandas`, `csv-parse`, manual bucketing,
+`pandas.resample`, …) in any of the ten languages. These run on the same Rust
+core as the indicators, so every binding reaches these speeds minus the FFI
+boundary characterised in section 3 (a `read` / `push` / `flush` call crosses the
+boundary once per batch, like `batch`, so bindings land close to the core).

+one-minute candles to five-minute bars ~0.2 ms. CSV parsing is the floor because
+it does the most per row (UTF-8 scan, field split, six `f64` parses, finiteness
+checks); aggregation and resampling are pure arithmetic over already-typed
+candles.
+
+The live and historical Binance feeds (`BinanceFeed`, `fetch_binance_klines`) are
+network-bound — their throughput is set by the exchange and the socket, not by
+Wickra — so they are not micro-benchmarked here; the relevant Wickra cost is the
+per-event parse, which is the same arithmetic measured above.

 ## [Unreleased]
 
+## [0.9.7] - 2026-06-21
+
+Maintenance release. The library API and every indicator are unchanged from
+`0.9.6`; this release carries an R package metadata fix and routine dependency
+and CI tooling updates.
+
+### Fixed
+- **R package: credit `kingchenc` as the package author and maintainer.** The R
+  `DESCRIPTION` was the only binding still listing "Wickra contributors" as the
+  sole `aut`/`cre` — an outlier introduced when the binding was added. It now
+  matches the Python, Node, and Rust core metadata, the package `.Rd` is
+  regenerated, and the binding `LICENSE` copyright holder is aligned with the
+  root `LICENSE-MIT`.
+
+### Changed
+- **Dependency and CI housekeeping.** Bump the C# test dependencies
+  (`Microsoft.NET.Test.Sdk`, `xunit`, `xunit.runner.visualstudio`), the GitHub
+  Actions used by CI (`setup-python`, `upload-artifact`, `codecov-action`,
+  `taiki-e/install-action`), and the Java benchmark's `org.wickra:wickra`
+  dependency. No runtime code changes.
+
+## [0.9.6] - 2026-06-18
+
+Documentation release for the R binding. The library API and every indicator
+are unchanged from `0.9.5`; only the R package's help pages change.
+
+### Fixed
+- **R package: document the data-layer exports and refresh the man pages.**
+  r-universe's `R CMD check` reported two warnings against the `0.9.3` data layer
+  it built for the first time in `0.9.5`: twelve undocumented exported objects
+  (`BinanceFeed`, `CandleReader`, `Resampler`, `TickAggregator`,
+  `fetch_binance_klines` and the `name` / `is_ready` / `warmup_period` / `push` /
+  `read` generics) and a codoc mismatch on `AwesomeOscillatorHistogram` (its help
+  page still listed `sma_period` after the argument was renamed to `lookback`).
+  The roxygen sources existed but the `man/*.Rd` had never been regenerated; they
+  are now complete, and a `push()` example that constructed a `TickAggregator`
+  without its required `gap_fill` argument is fixed. CI now runs `R CMD check` so
+  documentation drift fails the pull request instead of surfacing on r-universe.
+
+
+## [0.9.5] - 2026-06-17
+
+Maintenance release. The library API and every indicator are unchanged from
+`0.9.4`; the only change that ships to users is to the R package's build script.
+The rest of the release is CI / release-pipeline hardening (dependency caching,
+job timeouts, and network-install retries) that does not affect the artifacts.
+
+### Fixed
+- **R package: retry the C ABI download.** `configure` / `configure.win` fetch the
+  prebuilt `wickra-c-<triple>.tar.gz` from the matching GitHub release. A freshly
+  cut release can briefly return 404 while its assets propagate across the CDN
+  (and a transient network blip would also fail it), so the single-shot download
+  is now retried with a backoff (~2 min) before giving up. Fixes
+  `cannot open URL … 404 Not Found` on r-universe / source installs taken right
+  after a release.
+
+
+## [0.9.4] - 2026-06-17
+
+Packaging fix for the `0.9.3` data layer. The library is identical to `0.9.3` on
+every platform that already published; the only additions are an opt-in
+`vendored-tls` build feature and the Linux Python wheels, which `0.9.3` could not
+build.
+
+### Fixed
+- **Linux Python wheels (`manylinux` / `musllinux`) now build.** The `live-binance`
+  data layer links `native-tls` -> `openssl-sys`, which needs OpenSSL at build
+  time. The `manylinux` wheel containers ship no OpenSSL headers and the
+  `musllinux` build cross-compiles against a musl sysroot that has no OpenSSL at
+  all, so the wheels failed to compile. The Linux wheels are now built with a new
+  opt-in `vendored-tls` feature that compiles OpenSSL from source and links it
+  statically (no system OpenSSL required, on either libc). The native macOS and
+  Windows wheels were unaffected (Security.framework / SChannel). As a result
+  `0.9.3` shipped to crates.io, Maven Central, NuGet, and npm but not to PyPI;
+  PyPI publishes starting with `0.9.4`.
+
+### Added
+- **`vendored-tls` feature** on `wickra-data` (and the Python binding): builds the
+  `live-binance` TLS stack against a statically compiled OpenSSL. Off by default;
+  used by the release wheels and exercised on every PR by a `manylinux` /
+  `musllinux` container build-smoke CI job.
+
+
+## [0.9.3] - 2026-06-17
+
+### Changed
+- **Python: zero third-party dependencies — NumPy is no longer required**
+  (breaking). `pip install wickra` now pulls nothing else. Batch inputs accept any
+  sequence or buffer of numbers (`array.array`, `memoryview`, a NumPy array, or a
+  plain `list`); single-output `batch(...)` now returns a stdlib `array.array('d')`
+  and multi-output indicators return a buffer-protocol `Matrix` (with `.shape`,
+  integer-row and `[i, j]` element access, `.tolist()`) instead of 1-D / 2-D NumPy
+  arrays. Both expose the buffer protocol, so `numpy.asarray(result)` still wraps a
+  1-D result zero-copy when NumPy is installed — it is now an optional extra
+  (`pip install wickra[numpy]`). Streaming `update(...)` is unchanged, and results
+  are numerically identical. Single-output `batch(...)` is slower than the previous
+  NumPy path — a stdlib `array.array` cannot take ownership of the Rust result, so
+  it is copied rather than moved — though absolute batch latency stays in the
+  low-millisecond range. The other nine languages were already dependency-free.
+
+### Removed
+- **Python: `numpy` runtime dependency** (see *Changed*). NumPy moves to the
+  optional `numpy`/`test`/`bench` extras.
+
+### Fixed
+- **Binance kline feed: add the missing `3d` and `1M` intervals.** The
+  `live-binance` `Interval` enum was missing three-day (`3d`) and one-month (`1M`)
+  candles, two of Binance's 16 supported kline intervals. Both are now selectable
+  and map to the correct wire-format strings.
+
+### Added
+- **Native historical Binance REST kline fetcher in 9 languages (data layer).**
+  `fetchBinanceKlines` (Node.js / Python `fetch_binance_klines` / Go
+  `FetchBinanceKlines` / C# `BinanceFeed.FetchKlines` / Java `BinanceFeed.fetchKlines`
+  / R `fetch_binance_klines`; C / C++ call `wickra_binance_fetch_klines`) downloads
+  historical OHLCV candles straight from Binance's public REST endpoint — no
+  third-party HTTP/JSON client (`jackson`, `jsonlite`, `urllib`, …) needed. Pass a
+  symbol, interval, and limit (`1..=1000`) plus optional millisecond start/end
+  bounds; it blocks until the response arrives and returns the parsed candles. It
+  is built on `ureq` with native-tls, sharing the live feed's TLS stack, and is
+  covered by mock-HTTP-server tests. The historical counterpart to the live
+  `BinanceFeed`; WASM is excluded (browsers use the host `fetch`). Ships with the
+  C ABI's default `live-binance` feature.
+- **Native live Binance kline feed in 9 languages (data layer).** `BinanceFeed`
+  streams live OHLCV candles straight from Binance's public WebSocket — no
+  third-party WebSocket client (`ws`, `websockets`, `gorilla/websocket`, …) in any
+  binding. Construct it with comma-separated symbols + an interval, then poll
+  `next(timeout)` for the next event (or `null`/`None` on timeout); the connection
+  reconnects transparently. Exposed natively (Node.js / Python — a blocking poll
+  that drives the tested async stream on a tokio runtime) and over the C ABI as Go
+  `Next()`, C# `Next()`, Java `next()`, and the R `binance_next()`; C / C++ call
+  `wickra_binance_connect` / `_next` / `_close` / `_free` directly. The connect →
+  read → reconnect pipeline is covered by the existing mock-WS-server tests. WASM
+  is excluded (a browser has no raw sockets; use the host `WebSocket`). The C ABI
+  ships the feed by default (`live-binance` feature); the wasm build drops it.
+- **CSV candle reading in all 10 languages (data layer).** The `CandleReader`
+  parses a `timestamp,open,high,low,close,volume` CSV buffer (a leading UTF-8 BOM
+  and field whitespace are tolerated) into candles: construct it from a CSV string
+  and call `read()` for every candle in file order. Exposed natively (Node.js /
+  WASM `read(): Candle[]`, Python `read() -> list[tuple]`) and over the C ABI as Go
+  `Read() []Candle`, C# `Candle[] Read()`, Java `Candle[] read()`, and the R
+  `read()` S3 generic (an `n×6` matrix); C / C++ call `wickra_candle_reader_new` /
+  `_count` / `_read` directly. A cross-language golden
+  (`testdata/golden/data_csv*.csv`) pins the parsed candles identically across
+  every binding. This makes CSV backtest loading dependency-free in every binding.
+- **Candle resampling in all 10 languages (data layer).** The `Resampler`
+  aggregates candles into a higher timeframe (e.g. 1m → 5m): `update(open, high,
+  low, close, volume, timestamp)` returns the completed higher-timeframe candle on
+  a bucket boundary (else `null`/`None`/`NA`), and `flush()` emits the final,
+  still-open candle. Exposed natively (Node.js / WASM / Python) and over the C ABI
+  (Go / C# / Java return `(Candle, bool)` / `Candle?` / `Candle`; R via `update()`
+  and a `flush()` S3 method; C / C++ directly). A cross-language golden
+  (`testdata/golden/data_resampled.csv`) pins the resampled stream identically.
+- **Tick-to-candle aggregation in all 10 languages (data layer).** The
+  `TickAggregator` — roll trade ticks up into fixed-timeframe OHLCV candles, with
+  optional gap filling — is now exposed natively (Node.js / WASM `push(price,
+  size, ts): Candle[]`, Python `push(...) -> list[tuple]`) and over the C ABI as
+  Go `Push() []Candle`, C# `Candle[] Push()`, Java `Candle[] push()`, and the R
+  `push()` generic (an `n×6` matrix); C / C++ call the C ABI directly. The C ABI
+  uses a lossless two-step `wickra_tick_aggregator_push` / `_drain` so a single
+  push that gap-fills across many empty buckets never overflows a fixed buffer. A
+  new cross-language golden (`testdata/golden/data_*.csv`) pins the candle stream
+  identically across every binding. This is the first feature of a data layer that
+  makes the non-Rust bindings dependency-free for tick aggregation.
+- **`name()` on every indicator in all 10 languages.** The canonical
+  `Indicator::name()` / `BarBuilder::name()` accessor is now exposed through every
+  binding — Node.js `name()`, WASM `name()`, Python `name()`, and the C ABI
+  `wickra_<ind>_name()` surfaced as Go `Name()`, C# `Name()`, Java `name()`, and
+  the R `name()` S3 generic (C/C++ call the C ABI directly). The returned string
+  is the core canonical name, which may differ from the registered class name
+  (e.g. `ChaikinMoneyFlow` reports `"CMF"`, `Donchian` reports
+  `"DonchianChannels"`). A new cross-language golden (`testdata/golden/names.json`)
+  pins this name for all 514 indicators identically across every binding.
+
+## [0.9.2] - 2026-06-15
+
+### Added
+- **Cross-language golden parity for all 514 indicators across all 10 languages.**
+  A new `gen_golden` reference emits a deterministic OHLCV input series plus the
+  Rust output of every one of the 514 indicators to `testdata/golden/`. Each
+  binding now replays that shared input and is checked **bit-for-bit against the
+  Rust reference**, covering every archetype (scalar, multi-output, pairwise,
+  derivatives-tick, cross-section, order-book, trade, profile, alt-chart bars,
+  footprint):
+  - Python, Node.js, Java and R via reflection-driven runners.
+  - Go, C# and C/C++ via generated dispatch (`golden_all_test.go`,
+    `GoldenAllTests.g.cs`, `examples/c/golden_test.c` compiled as both C and C++).
+  - WASM via a `node --test` runner over the nodejs-target build.
+- CI now runs the WASM golden suite; the C/C++ golden tests run as `ctest`
+  targets in the existing C-ABI job, and the Python/Node/Go/C#/Java/R suites pick
+  up their golden runners automatically.
+- **README:** a "verified across 10 languages" badge (linking to the FAQ that
+  explains the cross-language golden parity) and a per-binding throughput table so
+  readers can pick a binding by its streaming FFI cost.
+
+### Fixed
+- **Java binding marshalled C ABI `bool` parameters incorrectly.** The
+  cross-section state flags (`newHigh`, `newLow`, `aboveMa`, `onBuySignal`) were
+  allocated as `JAVA_DOUBLE` arrays and passed to `const bool*` parameters, so the
+  native side read the low byte of each 8-byte double and saw every flag as
+  `false` (affecting e.g. `NewHighsNewLows`, `HighLowIndex`, `BullishPercentIndex`,
+  `PercentAboveMa`). They are now packed into a real `bool` buffer. `MacdExt`'s
+  `MaType` arguments are now passed as `byte` to match the `uint8_t` downcall.
+- **R binding marshalled C ABI `bool` flags incorrectly.** `(bool *)REAL(x)`
+  reinterpreted the 8-byte doubles as 1-byte bools across the 15 cross-section
+  update wrappers, reading every flag as `false`; the flags are now converted into
+  a real C `bool` buffer.
+- C# binding: added the `#nullable enable` directive the generated
+  `Indicators.g.cs` requires, clearing four `CS8669` warnings.
+
+### Changed
+- Renamed the `live_trading` examples to `live_binance` across the Python, Node.js,
+  WASM and C examples — they poll Binance market data, they do not place trades.
+- **Breaking — de-duplicated four indicators that computed identically to another
+  one.** Each is now its own distinct, correctly-defined indicator (the catalogue
+  stays at the same count):
+  - `AverageDrawdown` now reports the mean of the maximum depths of the distinct
+    drawdown episodes in the window (previously the per-bar mean under-water
+    fraction, which equalled `PainIndex`).
+  - `IntradayIntensity` now reports the raw per-bar Bostian intensity
+    `volume * (2*close − high − low) / (high − low)` (previously a cumulative line
+    that equalled the A/D Line `Adl`; its normalized form is `Cmf`).
+  - `AwesomeOscillatorHistogram` now reports the AO momentum
+    `AO[t] − AO[t−lookback]`; its third parameter is the momentum `lookback`
+    (default 1) instead of an SMA period (the old `AO − SMA(AO, n)` equalled
+    `AcceleratorOscillator`).
+  - `AdOscillator` is now the Williams **A/D Oscillator** (`WAD − SMA(WAD, 13)`),
+    distinct from the cumulative Williams A/D line `Wad`. Its native (Python /
+    Node.js / WASM) alias is renamed **`WilliamsAD` → `ADOSC`**.

+### Pick your language with eyes open — per-binding throughput

+Every binding calls the **same** Rust core, so this is **not** a speed claim — it
+is the raw cost of crossing each language's FFI boundary (`SMA(20)`, 200 000 bars,
+Ryzen 9 9950X, million updates/sec). **Batch stays high for most bindings;
+streaming is where the boundary shows** — so if you stream tick-by-tick, the table
+tells you which binding keeps up and which to avoid for hot loops.
