Minor issues

• The 'Why this is surprising' framing leans slightly toward novelty signaling; could be tightened to a more neutral observation about heterogeneous effects across modalities/endpoints.
• Receipt 2 excerpt is truncated mid-sentence in the source bundle, though this does not affect the memo's interpretation.

Reviewer note

The memo presents a clear, bounded research signal: cold-water immersion's effects appear modality- and endpoint-dependent rather than uniformly negative. Receipt 1 (2020) documents impaired training-load tolerance under heat-based training with CWI recovery; Receipt 2 (2018) shows CWI alongside sprint-interval cycling does not abolish fiber type-specific Na⁺,K⁺-ATPase isoform and FXYD1 adaptations in 19 recreationally active men. The two receipts are correctly grounded in the source bundle, with DOIs and excerpts matching the cited claims. The title ('modality boundary') aligns with the cross-context contrast between the two receipts. Limitations are well-handled: the memo explicitly notes the two studies differ on training modality, endpoint family, environmental conditions, and population dose, frames any moderator hypothesis as tentative, and provides a concrete falsifier (within-subject RCT holding modality and population constant). No clinical, policy, or broad consensus claims are made. Hedging language is appropriate and proportional to the evidence. The memo correctly identifies Receipt 2 as mechanistic context rather than direct replication of Receipt 1, preventing overclaim. Accept.
