docs/specs and docs/plans were retired (prior commit); the source/test
comments that cited them ("spec 0050 §4.1", "spec §Testing N", "per spec",
"the spec's ...") now point at nothing. Strip every such pointer while
preserving the technical substance, the design-ledger contract refs
(C1/C11/C20/C34/C12.1/...), and the Gitea issue refs (#41).
Comment/doc edits only across 20 files — no logic change; full workspace
suite green, clippy clean.
Hand-wires all seven new aura-std nodes (Resample, Delay, Gt, Session, EqConst
x2, And, Latch) + SimBroker into a raw-index FlatGraph over one synthetic
Frankfurt session, pinning the whole vocabulary composed end-to-end:
- held = [0,0,1,1,0] over the 5 bar emissions: flat, latched bar3-close (the
strict breakout landing on session bar 3) through bar4, exit at bar5-close;
- equity = [0,0,0,3,8] pips (SimBroker lagged-exposure integration, pip=1.0);
- a no-entry control (bar3 close == bar2 high) pins the strict-> semantic;
- two disjoint runs byte-identical (C1).
Both spec traps exercised (bar6 rollover closes bar5; bars 1-2 warm Delay[1]).
Phase-1 C9 deliverable; build-step 8 (capstone) of milestone 'Strategy node
vocabulary I'.

Ship the random half of the C12.1 param-sweep axis (grid landed in 0028).
A new `Space` trait (`points`/`param_specs`) generalizes `sweep`/`sweep_with_threads`
from `&GridSpace` to `&S: Space`; `GridSpace`'s trait impl forwards to its existing
inherent methods, so the grid path is behaviour-preserving (C1, every pre-existing
grid sweep test stays green). `RandomSpace` is the second `Space` producer: N seeded
uniform points over per-slot typed `ParamRange { lo, hi }` ranges (I64 inclusive
[lo,hi], F64 half-open [lo,hi)), validated in `new` against the param-space — a
non-numeric slot, a range-kind mismatch, and an empty range are the three new typed
`SweepError` variants, all caught before any run. Sampling reuses the existing
bit-stable `SplitMix64` (promoted to `pub(crate)`) as a code-path-disjoint instance
from the data-edge seed RNG — the #52/#71 World-II source-seam firewall: they share
only the `u64` type, never a path. The sweep-layer signature stays param-only
(`Fn(&[Cell]) -> RunReport`); no `Source`/stream type enters it.
Deviation from the spec's verbatim sampler, accepted as a correctness hardening:
the I64 draw guards the full-width span ([i64::MIN, i64::MAX] computes a span of
2^64 that wraps a u64 to 0) and uses `lo.wrapping_add(draw as i64)` instead of a
plain `+`. This avoids both the `% 0` divide-by-zero at the full domain and the
signed-overflow panic the literal form hits on wide ranges in debug builds, while
preserving uniform-over-[lo,hi] draws and determinism (an extra RED test,
random_points_full_range_i64_does_not_panic, pins it). Modulo bias for spans not
dividing 2^64 remains the spec's documented, accepted simplification (param search
needs no cryptographic uniformity).
Includes a public-API E2E suite (tests/random_sweep_e2e.rs) exercising the feature
exactly as a downstream researcher would — reproducibility at the report boundary,
seed-sensitivity, in-range draws, the typed NonNumericRange gate, a well-formed
empty (count==0) family, and Grid/Random interchangeability through `Space`.
Verified: cargo test --workspace green (incl. 17 new engine tests + 6 E2E);
cargo clippy --workspace --all-targets -- -D warnings clean.
