REAL-WORLD INTERPRETIVE
One-sentence brief
A current-state snapshot shows what the system believes now; an event history explains how it got there and which corrections must propagate.
REAL-WORLD INTERPRETIVE
SIMULATION LITERACY
Event Sourcing, Replay, and Branching
How append-only event history, snapshots, replay, and labeled branches can support reproducibility, correction, and counterfactual comparison.
LEVEL 1
ORIENTATION
Why this matters
REAL-WORLD INTERPRETIVE
Three key points
- Events record state change, actor, reason, version, and time.
- Snapshots improve performance but do not replace lineage.
- Counterfactual branches stay isolated from the observed or authoritative record.
LEVEL 2
WORKING BRIEF
Evidence, context, and limits
REAL-WORLD INTERPRETIVE
Event record
An event should describe the previous state, transition, new state, responsible rule or authority, timestamp, source references, and model version.
- Stable event identifier.
- Idempotent processing where practical.
- No sensitive personal detail beyond purpose.
REAL-WORLD INTERPRETIVE
Append-only history
Appending rather than overwriting preserves audit and correction history. Corrections can be represented as new events that supersede or reverse earlier state.
- Do not erase adverse results.
- Link reversal to original event.
- Protect integrity and access.
REAL-WORLD INTERPRETIVE
Snapshot
A snapshot accelerates loading by recording derived state at a point in time. It should include the event position and digest needed to verify reconstruction.
- Snapshot is derived, not primary evidence.
- Rebuild periodically.
- Detect drift.
REAL-WORLD INTERPRETIVE
Replay
Replay reconstructs state under the same rules and inputs. Reproducibility depends on deterministic order, versioned logic, and controlled randomness.
- Record seed or event outcomes.
- Pin dependencies.
- Compare replay digest.
REAL-WORLD INTERPRETIVE
Branch
A branch creates a counterfactual timeline from a known point. It should have its own identity, assumptions, and output store.
- Never merge fictional branch facts into observed history.
- Show divergence.
- Allow branch deletion without deleting the base record.
REAL-WORLD INTERPRETIVE
Rights, correction, and retention
Auditability should not become indefinite surveillance. Retention, access, correction, privacy, and deletion rules must be proportionate to purpose.
- Minimum necessary data.
- Independent review for consequential use.
- Correction reaches derivative records.

Limitations, game links, and review context
DISPUTED / MULTIPLE ACCOUNTS
Known limitations and gaps
- This is a non-operational educational transformation: it does not build or implement a game, executable simulator, forecasting service, emergency tool, or decision system.
- This page is an educational transformation of supplied research leads; it does not authenticate every citation, equation, product claim, or institutional attribution in those files.
- A scenario, model run, or map is not an observation, forecast, legal finding, public-health instruction, emergency warning, or proof of future behavior.
- No source code, nuclear-effects formula, casualty calculation, target-selection method, cyber-intrusion procedure, exploit chain, or instruction for bypassing safeguards is published.
- Geography, nationality, ethnicity, religion, language, migration, disability, health, poverty, or political identity are not inherent danger, compliance, intelligence, competence, or worth variables.
- Specialist scientific, public-health, accessibility, legal, regional, ethics, security, and lived-experience review remains pending; the page stays open to correction.
