Assessment

Why?

Strongest counted support: Stone-plus-spat-on-shell reefs had the highest structural complexity and the greatest abundance of fish exceeding 30 centimeters. weight 2.000000 evidence

Suppressed as dependent: The quoted passage directly supports greater structural complexity and larger fish for stone-plus-spat-on-shell reefs, but omits the six-to-ten-year interval and high-cover clause.

Review gaps: qualifiers reviewed, opposing search done, independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Leans supported.

• Independent coverage reports higher structural complexity and larger fish on stone-plus-spat-on-shell restored reefs.

  Secondary coverage corroborates the restoration-method comparison and fish-size result; it also preserves the important qualifier that total fish numbers were lower.

• The quoted passage directly supports greater structural complexity and larger fish for stone-plus-spat-on-shell reefs, but omits the six-to-ten-year interval and high-cover clause.

  Supports the habitat and fish-size comparison; the stated restoration interval and high oyster cover are not in this packet excerpt.

Evidence against

None.

Qualifications

• The comparison is a Maryland Harris Creek, six-to-ten-year post-restoration survey whose treatment effects vary by habitat and nekton endpoint rather than improving every fish metric.

  From Oyster reef habitat characteristics and nekton communities vary with restoration method in a large-scale project Read 2026-09-29 Relevance DIRECT Steps 0 Counted

  Adds site/area, follow-up interval, treatment categories, size threshold, method, and endpoint-specific nulls/tradeoffs.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
