Collections Compass: inspectable generated data

Coffeebeans · Team Members: Ayush Pattanayak and Pranshu Porwal

We built Collections Compass for the CIBC Collections Hackathon. This repository contains our current generated publications and quality evidence, kept outside GitHub because of their size. Every person, account, call and source document in the supplied Maple Bank release is synthetic. These are educational prototype artifacts, not CIBC customer data or operating systems.

Start here

Open the dataset viewer for verified_accounts to inspect 1,494,930 account-snapshot rows with verified ownership, original source keys, product/currency separation and lineage. Switch to identity_links to inspect unresolved and conflicting matches. We preserve uncertainty rather than treating every candidate as an owner.

Output	Rows	Meaning
Verified accounts	1,494,930	Owned account snapshots; balances remain separate by product and currency
Identity links	1,844,500	Verified, review-required, unresolved and conflicting links
CRM aliases	1,020,000	Source CRM IDs and conservatively resolved client IDs
Payment evidence	12,397	Selected promise-matched/reversal evidence from the supplied transaction release

The viewer calls each exported table a train split for browsing compatibility. These are inspection tables, not a model-training claim. The 1,015,228 resolved alias IDs are not a claim of perfectly matching all one million synthetic people.

What we generated

curated/ contains the exact three databases published by our build: Client 360, analytics and matched payments. Their JSON pointers preserve accepted versions and SHA-256 fingerprints. inventory.json records all tables, row counts, schemas and the corresponding code commit.

The C360 publication has 1,494,930 verified account links. We exclude 349,570 other account-snapshot rows from automatic owned totals: 43,720 need review, 293,772 are unresolved and 12,078 conflict. Those are account-snapshot rows, not distinct customer counts. Agreement scores are field-agreement measures, not calibrated probabilities.

Payment evidence comes from scanning all 12,401,924 supplied transaction rows across 220 partitions. Completeness applies to matching and reversals within the sampled release, not the complete bank ledger. Current analytics includes outcome fields for retrospective questions; those fields are not decision-feature inputs.

Inspect with DuckDB

Download a current database from curated/, then open it read-only:

import duckdb

db = duckdb.connect("curated/c360-20261003T072538295000Z.duckdb", read_only=True)
print(db.execute("SELECT status, count(*) FROM identity_links GROUP BY status").fetchall())
print(db.execute("SELECT system, product_type, currency, count(*) FROM accounts GROUP BY ALL").fetchall())

The application expects these database files and pointer JSONs together in its ignored data/curated/ directory. Other flows still need the organiser's released policy/transcript files. This artifact repository is not a standalone hosted application.

Evidence and limitations

contracts/c360.json extends DC-COLL-001. evidence/data-quality.md states affected-record counts and handling. The sample JSON contains actual released-client application snapshots. The final engineering run passed 1,044 checks; the 50-row benchmark was generated with no manual answer edits. Format validation does not establish factual grading. The semantic-review receipt separately records five independently reproduced numeric extras and known reference limitations.

The business snapshot is 28 September 2026. Prototype ingestion time does not reconstruct historical bank knowledge. A deposit balance is not repayment capacity. Hardship and other protective information cannot be used to prioritise recovery. No recovery uplift or preparation-time improvement has been measured.

Source: the organiser-supplied, fully synthetic Maple Bank Collections release. Our derived outputs preserve that provenance; this upload does not grant additional rights in the supplied source material. Raw release archives, obsolete publications, local review history, provider caches, credentials and audio are excluded.
