Bundles & Review

Reproducible bundles

Export comparison results as .scbundle archives (ComparisonBundle v1.0.0). Bundles are self-contained and cryptographically verified.

Bundle contents

File	Purpose
manifest.json	Bundle metadata, app version, comparison labels, alignment mode, privacy disclosure
repro/repro.json	Input fingerprints, preset hash, determinism seed, environment info
findings/deltas.json	Canonical deltas with confidence scores, anchors, trigger types, and debug info
findings/why.json	Human-readable explanations, guardrails, parameter chips, confidence breakdowns
findings/summary.md	Auto-generated Markdown summary
insights/insights.json	(optional) Insight feed events for the Review Mode insights tray

Bundles exported with the Audit profile may also include a repro/audit.json payload with full reproducibility audit data.

Bundle profiles

Bundles can be exported in three profiles:

• Share — standard export for team sharing
• Review — optimized for read-only review
• Audit — includes extended reproducibility and audit data

Integrity

Every file in the bundle is hashed with SHA-256. A bundle-level hash (computed over all individual file hashes) enables tamper detection. If any file has been modified since export, the integrity check fails and Review Mode will flag the discrepancy.

Privacy

The manifest includes a privacy disclosure block that records:

• Whether raw run data is included
• Whether any PII is present
• What redactions were applied (none, labels only, paths removed)

This lets recipients understand what data the bundle contains before opening it.

Review mode

Open any .scbundle without recomputing:

• Results are cryptographically verified against the embedded hashes
• Frozen deltas are displayed exactly as they were at export time
• A review-mode banner makes it clear results are verified, not re-derived
• The insights tray shows frozen insight events from the bundle
• Both parties see identical results when sharing bundles

Review mode is read-only — you cannot modify the bundle contents from within the app.

Reproducibility status

Each bundle tracks its reproducibility status:

• Reproducible — inputs and configuration match; results can be recreated
• Modified — something changed (inputs, preset, seed, or delta spec)
• Nondeterministic — results may vary between runs

The specific reason flags (inputs changed, preset changed, seed changed, delta spec changed) are recorded so you can trace exactly what diverged.

Export workflow

1. Complete a comparison in the Compare tab
2. Click Export Bundle in the bundle export panel
3. Choose a profile (Share, Review, or Audit)
4. Choose a location for the .scbundle file
5. Share the file with your team
6. Recipients open it in ScalarScope — Review mode activates automatically
