Financial statements over time
Financial statements change. Companies amend filings, restate prior periods, and reclassify historical results. Most data systems overwrite history and silently drift.
Arche models financial truth differently: every statement is treated as a versioned assertion, preserving what was known at the time while making change explicit.
Traditional pipelines assume there is a single “correct” statement. When restatements arrive, prior values are overwritten. Downstream systems lose the ability to reproduce analyses, explain discrepancies or answer audit questions.
- Deterministic as-of snapshots. Query financials as of a moment in time. Preserve versions. Reproduce results even after later filings modify prior periods.
- Explicit restatement deltas. Compare versions directly: what changed, by how much and whether the impact is material, without inference or manual diffing.
- Traceable provenance. Inspect lineage from filing → facts → rules → versioned assertions, so discrepancies are explainable under scrutiny.
The failure mode isn’t “dirty data.” It’s a data model that treats time and provenance as an afterthought. Arche makes both first-class, so change is modeled not erased.
