Task: Populate the credit family

Table of Contents

This page documents a task in the Populate the ACME books with a realistic trade population — the remaining work story. It captures the goal, current status, acceptance, and any notes or results.

1. Goal

A provisioned tenant holds credit trades, and every credit code the planner draws states a reference entity the data can be joined to.

3. Acceptance

  • The synthetic service resolves reference entities from the DQ lei_entity dataset and states them as LEI.
  • Constructors state each routed credit code, with the trade type fixed by the constructor.
  • A credit config books the family against IG CDS EMEA, proved by a provisioning run.

4. Plan

(Implementation strategy. Written when work starts; key decisions are distilled into the parent story's * Decisions at close, but the plan itself stays — it is the historical record of what we did.)

5. Measurements

Every number this task claims about a tree, with the command that produced it and the commit it was measured at. A number without both is not a measurement, because a clean-up record describes a tree and trunk moves under a branch: a consumer count, a gate's component count and a suite's size all change with no code changing, and the reader of a bare number cannot tell which tree it came from. Where the raw output matters, put it in an evidence/ file beside the task and name that file in the Command column.

10. Result

The family exists: constructors for its six routed codes, a planner that draws five of them, a writer arm, and a read path from the synthetic service into the DQ lei_entity dataset. It does not book, and the reason is not this family.

The DQ read returns nothing for a party session. The 38,213 legal entities sit in the DQ lei_entity artefact under the system tenant, and a session acting as a party reads its own tenant, so the planner's refusal fires: "The tenant holds no legal entity, so no credit trade can state a reference entity. Publish the LEI dataset first."

Measured: every row of ores_dq_lei_entities_artefact_tbl carries tenant_id = ffffffff-ffff-ffff-ffff-ffffffffffff, and acme_corporation is 484a4153-d7b6-46cf-b382-884d86ce8225.

So legal entities are world data recorded as if they were one tenant's, which is the split already captured as world data versus party configuration. Until that split reaches this dataset, no family can reference a legal entity, and the credit config is deliberately not seeded: with it seeded the provisioning run fails at generate_trades, and a green run matters more than an empty family.

Captured: The LEI dataset is system-tenant only, so a party cannot read it.

11. What is proved

  • The constructors refuse a reference that is neither LEI nor Internal, and an LEI that is not twenty alphanumeric characters.
  • The planner refuses a scope with no legal entity, by name, instead of booking a credit trade with no reference.
  • The provisioning run is green with no credit config, and the suites pass: ores.synthetic.core.tests 1741 assertions in 79 test cases, ores.trading.api.tests 548 in 147.
