Session, LinComb, and CostSum — the three builders the roster scope doc
excludes — re-shape onto the args seam (refs #271): builder() is now
zero-arg and returns a pending recipe (Session: tz + open; LinComb:
arity; CostSum: n_costs), the full signature forms in make, and
configured(...) is the Rust-path convenience producing the identical
recipe (twin-pinned). Session's period_minutes becomes a real ParamSpec
bound by configured instead of a baked struct field — same behaviour,
now sweepable when left open. Session::new and SessionFrankfurt are
untouched.
All builder(n)-form call sites move mechanically to configured(n):
aura-runner member.rs (wrap_r), aura-composites (vol_stop/cost_graph),
aura-engine blueprint.rs + e2e tests, aura-ingest breakout example,
and the crates' own tests. aura-std drops its unused chrono/chrono-tz
deps (stale since the b39fd63 session move).
The roster is deliberately untouched here: rostering before the op
seam lands would expose unconfigured pending builders to add_node.
The stage1 ordinal has been dead vocabulary since the C10 reframe dropped
the two-stage research model: a 1 structurally implies a 2 that no longer
exists. The family is renamed by its live discriminator - the R yardstick -
with members named by their signal, uniform with their signal-named
siblings (sma, macd, momentum):
- selectors: stage1-r -> r-sma, stage1-breakout -> r-breakout,
stage1-meanrev -> r-meanrev (old tokens are usage errors, exit 2 - no
silent alias)
- identifiers: Strategy::RSma/RBreakout/RMeanRev, HarnessKind::RSma,
r_sma_*/r_breakout_*/r_meanrev_*, wrap_r, run_signal_r, RGrid, R_SMA_*
- persisted identity: the sma_signal composite (param prefix
sma_signal.fast.length / .slow.length; fixtures regenerated; content-ids
shift - no test pins a literal hash, the registry parses no record names)
- e2e test files git-mv'd to r_sma_e2e / r_breakout_e2e / r_meanrev_e2e
- dead Stage-1/Stage-2 prose reworded to post-C10 vocabulary across
rustdoc, Cargo.tomls, ledger live lines, and the glossary (historical
entries stay; fieldtests corpus untouched)
- CLAUDE.md invariant 7 rewritten to record the ratified C10 reframe
faithfully (the token-swap alone would have laundered the retired
gated-currency/realistic-broker design into unmarked live prose); the
unbacked account-mode clause dropped
Verification: cargo build/test --workspace green (51 targets), clippy
-D warnings clean, doc build clean, acceptance grep gate leaves exactly
the one resampling-stage false positive (harness.rs), smoke: --harness
r-sma runs, --harness stage1-r exits 2 with the new usage line.
Decision log: forks and rationale recorded on the issue (reconciliation
+ implementation-phase comments).
