Cycle-close tidy for the generic portable sweep member-key + bool-param demo
strategy (spec/plan 0059, reference issue #105, implementations 27f850d + 0b73a75).
Architect drift review (range 1d6fafb..HEAD): clean — no drift, no debt.
- C1 (determinism): varying_axes + member_key are pure functions of the grid
point, no schedule state; the engine carries no trace state (consistent with
the #104 design + the C22/#101 ledger note).
- C7/C8/C9: LongOnly is a clean one-in/one-out f64 node, None until warmed (C8
filter), the first bool *param* through the already-ratified Cell::bool()
path; momentum is an ordinary composite of existing nodes; brokers stay
downstream (C10). C18/C21/C22 upheld.
- The engine accessor exposes the binder's OWN axis-cardinality knowledge (it
holds the value-lists), not a presentation concern — formatting stays in the
CLI. The hand-rolled fnv1a64 mirrors the ledger-blessed SplitMix64 precedent
(harness.rs): tiny, dependency-free, bit-stable-on-purpose (std DefaultHasher
is unstable across releases; on-disk-name stability is the per-case C16
reason). LongOnly is a genuine universal aura-std block (long-only is
asset-agnostic). The ledger amendment matches the code.
Regression: the project declares no dedicated regression command; the gate is
the architect review plus the full suite, verified green at 0b73a75 (cargo test
--workspace, clippy --all-targets -D warnings).
Spec docs/specs/0059 and plan docs/plans/0059 retired (git rm) per the ephemeral
active-cycle artefact lifecycle; the durable rationale (the portable member-key
convention) lives in the ledger amendment (docs/design/INDEX.md C22/#101 note)
landed in 0b73a75.
