# Reading planetary collisions in stardust

> EDITORIAL DRAFT — Public editorial drafts. Source inspection and claim standing describe the recorded evidence; they do not establish independent replication or scientific consensus.

A path from spectroscopy to the history of rocky worlds\.

## Claims

The reported sample comprised 21 extreme debris\-disc systems\, combining observations of 16 systems with Webb and five from archival Spitzer data\. [^1]

**Standing:** supported within scope. **Kind:** observation.
**Scope:** Reported sample and telescope allocation\; not all young planetary systems\.
**Limits:** Institutional release inspected\; underlying paper abstract\/metadata cross\-checked but full text and raw spectra remain uninspected\.
**Claim revision:** claim-debris-sample@2
**Review:** draft; method: separate agent scoped source cross check; independent review: not recorded. Scope: Independent editorial pass within the same agent team\; not independent scientific validation or replication\. Receipt: docs\/atlas\/source\-review\-2026\-10\-13\.md

- Evidence [^1] — supports; locator: Science release\: sample paragraph\, beginning with rarity and the 21\-disc sample. Inspection note: Relevant source sections re\-inspected by a separate editorial agent\; no scientific replication performed\.

The authors interpret silica\-rich debris as evidence consistent with energetic collisions between large planetary bodies\. [^1]

**Standing:** tentative. **Kind:** inference.
**Scope:** Authors\' interpretation of silica\-rich spectra in a selected sample\.
**Limits:** Planetary impacts and impactor sizes are inferred from spectra and physical models\. Collisions were not directly observed\; mineralogy\/age interpretation remains to be tested in larger samples\.
**Claim revision:** claim-debris-interpretation@2
**Review:** draft; method: separate agent scoped source cross check; independent review: not recorded. Scope: Independent editorial pass within the same agent team\; not independent scientific validation or replication\. Receipt: docs\/atlas\/source\-review\-2026\-10\-13\.md

- Evidence [^1] — supports; locator: Science release\: mineralogical categories and approximately one\-third silica\-rich fraction. Inspection note: Relevant source sections re\-inspected by a separate editorial agent\; no scientific replication performed\.

## Open question

Which additional observations would discriminate collision mechanisms\?

This is a research question, not an executed experiment.
