Study 000N: Prospective Envelope-State Markers
Study 000N asks a practical next-step question: can the archive identify support state before a run instead of only after burden outcomes are observed?
Study 000N now supports a settled archive-level answer. The archive supports a prospective marker hierarchy and not one universal fixed readiness threshold.
The strongest candidate markers are local running-share context and treadmill-neighbor density. Since the wider full-archive pass, the marker landscape has also broadened to include sleep architecture, daily wellness, hydration, late-window health status, fueling overlap, and hybrid support ecology. In the refined answer, resting-HR wellness state emerged as the strongest broad secondary refiner, while the other families remained partial, late-window, or mode-specific refiners.

Headline Finding
The archive supports prospective envelope-state reading, but it is hierarchical and mode-sensitive, not globally threshold-stable.
Running-share context and treadmill-neighbor density prospectively separate the October 2025 high-burden outside cluster from the mature April 2026 low-burden boundary state. They also separate the two short early positive-burden probes from the later mature supported state.
What they do not do is fully explain the early low-burden 10.2265 mile outside success route, which appears to belong to a different successful mode.
Why This Study Exists
The archive already supported adaptive-envelope behavior in Study 000I, strong support-factor candidates in Study 000H, state-conditional support architecture in Study 000J, and multiple successful low-burden modes in Study 000K.
What remained unresolved was whether the archive had any forward-usable envelope-state markers that could be read before a run instead of inferred only from the burden outcome afterward.
The later full-archive analytic pass and secondary hybrid-support work expanded that marker search beyond simple running-context measures. That refinement closed the core study question by showing a hierarchy: primary embedding markers first, resting-HR wellness next, then partial or mode-specific refiners like sleep, HRV, support ecology, hydration, and fueling.
Marker Family 1: Running-Share Context
Running-share context rose from 5.1299% in the October 2025 high-burden cluster to 91.0839% in the April 2026 low-burden boundary probe. That is a major prospective difference in local state.
Marker Family 2: Treadmill-Neighbor Density
Treadmill neighbors over 21 days rose from 1.75 in the October 2025 cluster to 32.0 in the April 2026 boundary run, making local stabilized-context continuity one of the strongest pre-run separators.
The Exception That Matters
The early low-burden 10.2265 mile outside run remained the key exception. It succeeded with only 28.2459% running-share context and 3 treadmill neighbors. That is exactly why the study does not support a single simple readiness cutoff.
The best full-program reading is that prospective state reading now works better than before, but it still has to be interpreted through a mode-sensitive framework and not one rigid universal score.
What Study 000N Adds
It Makes The Archive More Practical
The program is no longer limited to retrospective interpretation. It now has a first workable forward-reading layer with a usable marker hierarchy instead of a single forced readiness score.
It Protects Against Overclaiming
The study does not force one universal threshold where the data do not support one.
It Strengthens Multi-Mode Logic
The exception case confirms that the archive still contains more than one successful route to low-burden expression.
What Strengthened Study 000N Later
Full-Archive Family Expansion
A wider archive pass made the candidate marker pool much more explicit. Sleep architecture, wellness, hydration, health-status data, and fueling overlap all became credible state families, not generic background context, even though they did not displace the primary embedding pair.
Hybrid Support Ecology
Secondary Study SS001 showed that hybrid support ecology was not just noise. That matters here because support ecology is now a realistic mode-specific contributor to prospective envelope-state reading, especially when double-day structure is present.
Plain-Language Summary
This study asked whether the archive could tell, before a run happens, what kind of support state the system is in.
The answer is yes, partly. Recent running share and nearby treadmill density do a good job of separating clearly high-risk states from clearly supported states.
But they do not explain everything, because one early long outdoor success happened with only modest support markers. So the archive now supports a marker family, not one universal readiness line.

Author Experience
This page is part of a patient-led altered-mechanics research archive built from one documented case with long-term structural constraint, surgical history, and a multi-year wearable record.
Evidence Boundary
The data are wearable-derived and observational. Study 000N tests candidate pre-run markers for envelope state. It does not claim universal thresholds, joint-level biomechanics, or medical causation.

FAQ
What are prospective envelope-state markers?
They are measurements that can help identify support state before a run instead of only after burden outcomes are observed.
Which markers were strongest?
The strongest established candidates were local running-share context and treadmill-neighbor density, with resting-HR wellness as the strongest broad secondary refiner and broader state families like sleep, HRV, hydration, fueling, and support ecology acting as meaningful extensions of the marker search.
Why is the early long run so important?
It is the exception that prevents overclaiming. That run shows one successful route existed without dense support markers, which is why the archive supports a marker family and not one universal threshold and instead supports a hierarchy.
Is the main question behind Study 000N fully closed?
Yes, at the current archive level. The settled answer is that the system behaves like a hierarchical, mode-sensitive marker problem instead of a single-threshold readiness problem.
