• Check grammar, formatting, and style

Summary

The change replaces an inaccurate sentence (which implied fingerprinting feeds into quarantine decisions) with corrected copy clarifying that fingerprinting is used for triage/surfacing differences, and quarantining is a separate mechanism. This matches the PR description: "Fingerprinting is not currently a quarantining input."

Findings

✅ Factual fix is correct and the previous wording (quarantine decisions "based on the actual failure pattern" + "if it fails in a new way, CI fails normally") is appropriately removed since that behavior isn't accurate.

✅ Sentence count reduces from 4 → 3, which tightens the paragraph without losing meaning.

✅ No typos, formatting, or markdown issues.

Minor style nit (non-blocking) — welcome.md:31

We quarantine flaky tests so that if a quarantined test fails, CI passes.

The "so that … if … then" construction is slightly clunky and repeats "quarantine"/"quarantined". A tighter alternative:

We quarantine flaky tests, so their failures don't fail CI.

or

When a test is quarantined, its failures no longer fail CI.

Up to the author — the current wording is clear enough.
