Nanopublication — The Pun in the Pigment: a genuine double-invariant, but the return half of the loop is never shown

What the source says ^[1]

An obituary for painter Mary Lovelace O'Neal (1942–2026), who refused affiliation with either Minimalism or Abstract Expressionism, insisting 'I call myself a painter.' In the 1960s she rubbed raw lamp-black pigment into white canvases, producing flat, black paintings that doubled as a rejoinder to Black colleagues who told her the work wasn't 'Black enough' — she argued the paintings answered both a social question of Blackness and a theoretical question about Black abstraction. In 1979 she pivoted sharply to a series called 'Whales Fucking,' inspired by watching whales migrate off a California beach. The piece traces her path from Howard University and SNCC activism through Skowhegan, Columbia, and decades teaching at Berkeley, to belated critical recognition via a 2020 Mnuchin show and the 2024 Whitney Biennial.

Where the lens grips

P3a and P19a grip specifically on the lamp-black episode: the physical invariant (flat black surface, received by any viewer as material fact) is distinct from an intentional invariant (a punning argument about 'Blackness' as both social and theoretical category) that stayed latent — genuinely mute to her Black colleague-critics at the time — and only became activatable through her later interview dialogue (Bomb, 2021). P14b grips on the 1979 turn to 'Whales Fucking': a stable practice destabilized by an unplanned encounter (witnessing whale migration) and recomposed at a new register while remaining within gestural abstraction — matching the proposition's own shape of periodic destabilization and deeper recrystallization.

Where it breaks

The grip holds for the punning-blackness case precisely because retrospective dialogue actually occurred and is documented (the Bomb interview). But the source never shows the other half of the mechanism: how her Black colleague-critics responded once she explained the codex. P18a's claim that revelation generates a new, productive tension in the receiver — the bilateral ricochet — is asserted by the proposition but simply not tested by anything in this obituary; the source supports the latency/explicability half and is silent on the return half.

Propositional grid ^[2]

Read this grid. “Not evaluated” does not mean the source has nothing to say about that proposition. It means the reading did not instruct it. That is not a result, and it counts in no denominator. A silence, by contrast, is a finding: the reading touched the proposition without concluding, or noted its absence itself.

Evaluated

Not evaluated (32) — P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P14a, P15, P16, P16a, P17, P18, P19, P20, P22, P23, P24, P25, P26, P27, P28, P29, P30, P31

First pass — kept as written

Reading produced by the T50 RSS pass, before the boundary lens. It is reproduced UNCORRECTED. Keeping it is the point: without it, a changed title is just a changed title — with it, what the second pass refused becomes legible.

Title it carried : « Mary Lovelace O'Neal's Refusal and the Met's Hair Dress: Codex Violation and Institutional Diffraction »

O'Neal's deliberate constraint—paintings composed almost entirely of black pigment despite institutional pressure to produce a 'Black aesthetic'—is a crystallized codex: a formal system of self-imposed limitations that generated meaning precisely through refusal of recognition. She engineered diffraction by making her ouverture (her position as a Black abstract painter) work against the expected signal (identity-legible art). The accusation that she 'failed to reach a Black aesthetic' reveals the dilution crisis: institutions demand maximum emission (recognizable identity markers) and minimum diffraction (singular, non-negotiable interpretation). O'Neal's resistance—her insistence on the invariant beneath the signal—is ideamorphic practice.
