To resubmit, address

1. Sharpen the bounded signal: explicitly state whether the claim is (a) CWI has context-dependent effects depending on training modality/environment, or (b) something more specific. Drop the 'modality boundary' framing unless the receipts can be shown to share a common training-modality axis (currently they differ on modality, environment, and endpoint).
2. In the alpha-sentence, make clear what is established vs. what is speculative. Receipt 1's negative effect on training-load tolerance is the only direct finding; Receipt 2's role is currently descriptive. State whether Receipt 2 confirms, qualifies, or is orthogonal to Receipt 1.
3. Add a concrete falsifier tied to the actual claim: e.g., a third study showing CWI does not impair training load in non-heat contexts, or showing K+ transport adaptations are blunted by CWI with a performance correlate.

Major issues

• The two receipts examine fundamentally different endpoints (session-RPE training load in heat-based training vs. fiber type-specific K+ transport protein abundance in sprint-interval cycling), and the memo does not adequately explain why these constitute a coherent 'modality boundary' signal rather than a mismatched pair. The 'Why this is surprising' section itself concedes the receipts do not directly overturn the uniform recovery/adaptation expectation, undermining the bounded research signal.
• The title/topic promises a 'modality boundary' but the memo does not provide a falsifiable claim about what the boundary actually is or where it lies. Receipt 1 is about heat-based training context, not a training modality per se, while Receipt 2 is about sprint-interval cycling with a molecular endpoint. The cross-modality framing conflates training modality with environmental context and endpoint type.

Minor issues

• The alpha-sentence could more precisely state what the bounded signal is rather than describing what each receipt examines.
• The phrase 'homogeneous signal' is not used, but the memo's framing implies the receipts form a coherent pair when the caveats section correctly identifies they are heterogeneous — this internal tension weakens the signal.
• Receipt 1's sample size is flagged as unverifiable, yet no concrete statement is made about what population/size would strengthen the signal.

Reviewer note

The memo identifies two real receipts on cold-water immersion with different endpoints (training-load tolerance in heat-based training; fiber type-specific K+ transport protein adaptations to sprint-interval cycling). The source_grounding is strong — both citations are real, recent, and directly relevant to the topic. However, the 'modality boundary' framing is not fully supported by the cross-axis heterogeneity the memo itself documents. The alpha-sentence is appropriately hedged and limitations are specific and material. The main weakness is that the bounded research signal is not clearly articulated: the memo oscillates between claiming a context-dependent trade-off and acknowledging the receipts do not directly link. This is salvageable with a tighter framing that either (a) narrows the claim to Receipt 1's heat-based training-load finding and treats Receipt 2 as orthogonal, or (b) reframes the memo as a heterogeneous cross-context signal rather than a modality boundary. Revise is warranted because the manuscript is honest about limits and the sources are solid, but the central signal needs clearer articulation.
