The skill had mtb-xco-demands.md but road/TT demands were only diffused
through the general docs — an asymmetry given the balanced MTB+road scope.
Add two dedicated, self-contained demand profiles (kept separate because
mass-start racing and TT differ as much as XCO differs from marathon MTB):
- references/road-racing-demands.md: stochastic power profile (Vogt 2007,
Ebert 2005/2006, Sanders/van Erp 2021), drafting economics (Blocken 2018),
fatigued finishing sprint (Menaspà 2013/2015, Etxebarria 2019), durability
as a success determinant (van Erp/Sanders/Lamberts 2021); power governs, HR
unreliable (intermittent) — mirrors the MTB doc.
- references/tt-demands.md: aero drag dominance + CdA as the top lever
(Crouch 2017, Martin 1998, García-López 2008), critical power as predictor
(Smith 1999), even-vs-variable pacing (Swain 1997, Atkinson 2007), long-TT
durability (Maunder 2021); HR more usable than MTB but still secondary.
All new quantitative claims carry verified PMIDs/DOIs (verified via PubMed/
CrossRef); citations.md gains Road-racing and Time-trial sections. Honesty
flags: Blocken 2018 and Martin 1998 have no PMID (DOI only); the '~90% aero'
soundbite (Kyle & Burke 1984) is unverifiable and marked approximate;
criterium-specific literature flagged as a gap; no unverified HR-reliability
citation added (TT HR defers to data-confounds.md).
Router (SKILL.md) and README layout updated with both docs.
