PSAR — the wiki page still claimed "Node streaming. Not exposed in the
Node binding." That was true for an early release but is no longer:
the Node binding has exposed `psar.update(high, low, close)` since the
B1 fix in todo-detailed.md, and the WASM binding now exposes the same
streaming surface (audit finding R3, this branch). The page lists all
three streaming + batch shapes and adds a paragraph on the new
`is_ready` convention (audit finding R6 — flips on the first non-None
SAR, not on the seed candle).
HistoricalVolatility — the "Non-positive prices" edge-case note still
described the old behaviour ("that return is treated as 0"). The new
behaviour skips the bad tick entirely (audit finding R13): the
indicator's state is left untouched, the previous valid value is
returned, and the next real tick re-anchors against the previous
*valid* price. Updated the note to describe the new behaviour and
explain why (silently treating bad ticks as "no movement" underreports
realised volatility).
The original taxonomy was four classical families plus a statistics group,
with the F1-F12 expansion slotted in as sub-categories. This regroups the
whole 71-indicator catalogue into eight top-level families, each with at
least five members:
Moving Averages (12), Momentum Oscillators (13), Trend & Directional (9),
Price Oscillators (5), Volatility & Bands (12), Trailing Stops (5),
Volume (9), Price Statistics (7).
- Wiki: docs/wiki/indicators/ reorganised into eight family folders; all 71
indicator pages moved with `git mv`. Every internal cross-link is
normalised to `../<family>/Indicator-X.md`, each page's `Family` field is
set to its new family, and two pre-existing `../Indicator-Chaining.md`
links (should have been `../../`) are corrected. A link check confirms
every relative wiki link resolves.
- Indicators-Overview.md fully rewritten around the eight families;
Home.md indicator reference and the README family table follow suit.
- Warmup-Periods.md gains the eight F13 indicators; CHANGELOG records the
46-indicator expansion (25 -> 71) and the eight-family taxonomy.
- Tests: Node indicators.test.js and Python test_new_indicators.py cover
all eight new indicators (Node 91/91, Python 117/117 green).
cargo fmt + clippy (core/wickra/data/wasm/node) clean; 508 core tests,
25 data tests and 74 doctests green.
