The structural risk-regime axis worked end to end but was invisible on the
public surface (refs #216): the --unwired probe swept only required slots
(risk is #[serde(default)]), no vocabulary block described RiskRegime, and
the validate summary counted axes/windows but no regimes or cells.
- open_slots_campaign gains its one optional-slot probe: a risk-less (or
empty/non-array) document lists
'open slot: risk (optional, list of stop regimes { vol: { length, k } };
absent = one default regime)'; a bound list closes the slot. Never a
required flip — content-id parity of risk-less documents is load-bearing.
- CAMPAIGN_SECTIONS gains std::risk (SlotKind::Regimes, required: false) so
--vocabulary lists it and --block std::risk describes the regime shape.
- The intrinsic validate summary now reports the realized matrix, mirroring
the exec cross-product exactly (strategies x instruments x windows x
regimes; empty risk = one default cell, marked '(default)'). Points stay
a grid property, deliberately not a cell factor.
Sanctioned migrations (recorded on #216): the two unit pins encoding the old
invisibility — open_slots_report_partial_documents_by_path now pins exactly
one open slot on the complete risk-less fixture (doubling as the probe's
unit pin; fixture bytes unchanged), and the presentation-hint test migrates
from full-vector equality to locating its entry (its purpose is the hint
text, not the vector length).
Verified: cargo test -p aura-research (29/0), -p aura-cli --test
research_docs (60/0), clippy -D warnings clean.
