# The given invariant survives in the museum; the instituted one was never collected — the split names the gap, not why it happened **Artwork**: **Artist**: Arnaud Quercy **Asset**: IDS-RNI0238 **Serial**: NAN-RDG000191 The boundary sits between describing the split and explaining it: the given/instituted distinction correctly names what survives and what doesn't, but stops exactly where the article's actual argument begins — institutional and racial selection determines which codices get archived at all, and that causal question is outside what P3a's mechanism can address. ## Context ⓘ **Thin page** — the source itself is thin (teaser, notice, paywalled preamble). Distinct from truncation: nothing was cut by the pipeline. ### What the source says [@source] The article argues that Black American natural-pigment traditions — indigo dyeing, Malian mudcloth, and George Washington Carver's paints made from peanut oil, Alabama clay, and vegetables — are absent from institutional craft archives despite their scale and historical importance. Carver's 71 surviving paintings are housed at Tuskegee, but his identity as artist and pigment-maker is consistently overshadowed by his fame as an agricultural scientist. The author, unable to find any archive devoted to Black American natural color-making, treats this absence itself as evidence of what institutions chose to value and preserve. ### Where the lens grips P3a's given/instituted split lands cleanly on the case: Carver's paintings — the material fact, dimensions, pigments, surfaces — are the given invariant, intact in the Tuskegee archive and 'received as constraint' by any visitor. What the article says is missing is the instituted invariant: the craft logic, the lineage connecting his pigment recipes to broader Black dyeing traditions, the 'why these materials' — never disclosed or stabilized as a codex by any archive. P10's claim that 'the wave outlives the emitter if the material survives' also gets a literal instance here: the paintings persist; the informing tradition, per the article, largely did not. ### Where it breaks The article's own explanation for the instituted invariant's failure to persist is not a generic risk of 'codex instability' but a specific, named cause: archives that systematically valued Carver's science over his art, and that never devoted collection effort to Black vernacular pigment-making at all — 'why do we celebrate finished works while overlooking the craft traditions — and people — that produced their color?' P3a models robustness as a property intrinsic to the codex's own stability; it has no vocabulary for an archive actively declining to collect, or for a racialized hierarchy that ranks 'science' above 'craft.' The lens can name that the instituted invariant is missing; it is silent on why it was never given the chance to be disclosed. ### Propositional grid [@p31] > **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**
