C29 compile/unit seam, task 3 of the self-description plan: every
aura-std NodeSchema literal threads its one-line doc. Four texts were
corrected against the actual eval/finalize semantics rather than taken
from the plan table verbatim: Delay is a lag-N register (not one-step),
GatedRecorder flushes an ungated final row at finalize, Latch is a
level-sensitive set/reset register (captures no input), SeriesReducer
emits its single summary row at finalize (not per cycle).
Gate: cargo build -p aura-std --lib clean; full std test run follows at
the all-crates gate once strategy/backtest/engine thread their sites
(the earlier per-crate test gate was unsatisfiable in isolation --
std's dev-deps pull crates whose sites belong to later tasks).
refs #316
Five new rostered node types (count-pin 23 -> 28, both the in-crate
shape test and the cross-boundary CLI vocabulary e2e): Const is unary
with an f64 'value' param — the clock input drives it, its value is
ignored, since a zero-input node never evaluates in the total-push
engine — mirroring EqConst's constant-as-param pattern; Div is binary
IEEE-754 (x/0 -> signed inf, 0/0 -> NaN, unit-tested, no error
channel); Abs unary mirroring Sqrt; Max/Min binary pairwise, distinct
from the windowed RollingMax/RollingMin.
Acceptance proof: the committed executable spec composes an RSI-class
gain/loss-split-and-ratio signal purely from blueprint data through
std_vocabulary and runs it to hand-computed RS values — the r_meanrev
constant-folding workaround is no longer forced.
Verified: headline test green, aura-std 163/0, full workspace suite
green (independent mini-verify), clippy -D warnings clean.
