Three indicator pages get a short follow-up paragraph that surfaces an
internal implementation detail the audit findings made user-visible:
- `Indicator-LinearRegression.md` gains a "Complexity" section explaining
the O(1) update (precomputed `Σx`, `Σxx`; incrementally slid `Σy`,
`Σxy` via the closed-form sliding identity), and the existing
"Reset" bullet mentions the additional running accumulators. The same
story applies to `LinRegSlope` and `LinRegAngle` (the page now links
to both rather than repeating the derivation three times).
- `Indicator-Sma.md` and `Indicator-BollingerBands.md` mention the
periodic reseed (`16 · period` updates) that caps floating-point
drift on long-running streams. Amortised cost is still O(1) and the
user-facing behaviour on benign inputs is unchanged.
No behavioural claim, no API claim, no example changes — just narrative
catching up with the implementation.
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.
