Labels stay evidence labels. A consuming surface keeps Supported, Partially supported, and Unresolved — it must never relabel them earned / partial / held merely because the color value is shared. The three reused values are visual-role mappings (one exact: unresolved → held), not semantic aliases.

• weakened // a tonal derivative of partial: the same 30° hue family, lower saturation and lightness — a muted, darkened orange ("brown"). It reads as a degraded partial (the pathway remains viable but has lost credibility), clearly separated from neon partial and from red deflated. It is not a new wheel position and is not added to the Spectral State health ramp.

• not-yet-testable // off the chromatic arc entirely: a neutral lavender-gray for "evidence cannot exist yet at this stage" (distinct from unresolved, an open question being worked, and from a neutral field with no asserted state). Color alone is not sufficient. Its presentation contract is mandatory:

  neutral lavender-gray  +  dashed rail  +  hollow marker  +  visible label

Evidence State draws on the same neon wheel as Spectral State. The three reused values sit on it (earned 120°, partial 30°, held 180°); weakened is a tonal branch of the 30° orange; not-yet-testable is achromatic (off the wheel), like the neutral field. The sparse-signal discipline carries over: a node takes color only to say something.

The Spectral State health ramp is unchanged:

Spectral State ramp (unchanged)
  earned → structural → partial → deflated

Evidence State derivation
  partially-supported  → value of partial
  weakened             → muted 30° brown (tonal branch of partial, off the ramp)

• Tier 1 (identity-free): the --evidence-* role names — a stable vocabulary other ASK-family surfaces can reuse.
• Tier 2 (ASK design language): the two new per-theme values (weakened brown, not-yet-testable lavender-gray); the three reused values inherit Spectral State's Tier 2 by reference.
• No Tier 3. This profile carries no instance identity.

1. Load colors_and_type.css, then spectral-state.css, then evidence-state.css.
2. On a consuming element, set color from a single role token, e.g. fill: var(--evidence-supported) or color: var(--evidence-weakened).
3. For not-yet-testable, apply the full presentation contract (lavender-gray + dashed rail + hollow marker + visible label) — never color alone.
4. Keep the evidence labels visible; do not relabel reused roles by their Spectral State names.
5. In a document, the Review Semantics annotation composition shows an evidence role as a labeled dot and keeps the not-yet-testable contract whole. Evidence State's other presentations are unaffected.

/* example — consuming surface */
.node[data-evidence="supported"]           { color: var(--evidence-supported); }
.node[data-evidence="partially-supported"] { color: var(--evidence-partially-supported); }
.node[data-evidence="unresolved"]          { color: var(--evidence-unresolved); }
.node[data-evidence="weakened"]            { color: var(--evidence-weakened); }
.node[data-evidence="not-yet-testable"]    { color: var(--evidence-not-yet-testable);
                                             border-left: 2px dashed var(--evidence-not-yet-testable); }

• Upstream (this repo): the five role names, the two new per-theme values, the reuse-by-reference mapping, and the not-yet-testable presentation contract. General; family-reusable. Consumers inherit by reference and do not mint a divergent palette.
• Consumer-local (e.g. urban-observatory): which element carries which evidence state, evidence-depth qualifiers, change-state (revised / deferred) badges, source pointers, and the surface layout. Those are data and metadata, not part of this color profile. urban-observatory consumes Evidence State by reference as a domain-partner consumer; the surfaces stay separate sources of repo truth under one ASK source-of-intent.
