Module reference 

London Strategic Edge catalog records (GET /vault/catalog).

The catalog is the provider’s index of everything it publishes: 22,966 entries at the last measurement, spanning the price datasets that LseDataset models, the reference families (economics, bond yields, credit indices, …) that it deliberately does not, and options, which is a price dataset that has no LseDataset variant either — see LseCatalogEntry::price_dataset.

LseCatalogEntry is the record exactly as the vault serves it — a provider-shaped type in the same spirit as AlpacaStockSplit, not a provider-agnostic abstraction. Nothing here is wired into the engine: reference series are live == 0 across the board and reach a backtest, if at all, through an auxiliary event source rather than through price() or orders.

Classifying an entry

LseCatalogEntry::class separates price datasets from reference series using the provider’s own fields, and the rule is not a heuristic: across all 22,966 entries, a populated frequency and category identifies a reference series and an empty pair identifies a price dataset, with zero rows falling outside either bucket (15,537 reference / 7,429 price). A new dataset the provider adds tomorrow therefore classifies itself, with no list here to update.

⚠️ frequency is a label, not a cadence contract

It is kept as the provider’s own string rather than parsed into an enum, for two measured reasons. The vocabulary is dirty: ten distinct spellings including biannually and bi-annually, quarterly and quarter — so a closed enum built from the obvious six values would have silently mishandled seven rows. And the label does not predict observed spacing: weekly series range from 52 to 248 observations per year, and quarter yields roughly 1.5, not 4. Derive expected spacing from the observations themselves, never from this field.
