0002 — Researcher rulings on the engineer's five questions

2026-08-21. The researcher's answers, verbatim, then the design consequences extracted from each. Per §110 the native concepts are preserved; formalizations below are candidates adjacent to them, not translations replacing them.

1. Layer-2 encoding

"my default is that anything has multiple descriptions. words, shapes, images, vectors, math, sequence, time. what we really dont want to do is compress it all into the same LANGUAGE aka language. this has to hold many types"

Ruling: the dilemma (fixed vocabulary vs freeform relations) is dissolved by rejecting its premise — there is no single Layer-2 scheme. Consequence: representation.content is scheme-TYPED, and the store holds many types (graph, sequence, geometric, numeric, prose...) of the same artifact simultaneously. Prose is one type among several, never the canonical one (§74 hardened from warning to rule). Comparators are scheme-pair objects; the absence of a comparator between two schemes is a recorded fact, not a bug to fix. Experiment 0 changes: parses must span at least two genuinely different types, not two readings within one type.

2. Parser variance vs artifact variance

"read something once it may or may not land, think about it later and it might. doesnt mean you reread it, you retreaded the dents it made."

Ruling: my binary (artifact structure vs parser habit) is missing the third term. A parse is artifact × the dents it left × later traversal of those dents. Part of "parser variance" is the artifact's operative payload acting on the parser (§4, §39) — which is measurement of the artifact, not noise. Consequence: variance decomposition gets three terms — artifact main effect, parser main effect, artifact×parser interaction (the dents). Deferred experiment (recorded, not built): the retread protocol — a second pass over one's own earlier parse without the artifact present, vs a fresh reread; what develops from dents alone? (jane's reconstruct.py was this experiment run on a self.)

3. Weighting / GED costs

"the thing is going to have subjective opinions based on what its exposed to thats the point. disagree feed more, still disagree? maybe im wrong."

Ruling: weighting is not contamination to minimize — it is the instrument's taste, exposure-dependent, arguable-with, and permitted to outlast the researcher's disagreement. Consequence: weighting objects are versioned STATE with exposure provenance (what the instrument had been fed when this weighting held), updated by feeding, never by editing. Hand-set GED costs are only the day-zero prior. The dispute protocol is native: disagree → feed more → persistent disagreement is a result about researcher or instrument, and the record shows which corpus grew the taste. Held tension (deliberate, §104): instrument-with-taste vs §32 (self-conviction) and §30 (shared priors). Resolution is NOT neutrality — it is taste-with-provenance, confronted by critics and nulls like every other producer. Subjective ≠ unaccountable.

4. Nulls

"nulls should be a self-evident occurance you see a shape like another shape but its missing a piece. this is a thing to notice."

Ruling: nulls are primarily observed near-misses, not synthesized distributions. A mapping that almost works, minus a piece, is a first-class object — the missing piece is the datum. Consequence: every partial/failed correspondence is retained into the control population (§53 upgraded: negative results are not just product, they are the reference field against which interestingness is measured). Synthetic nulls (rewiring, permutation) become supplements for when the observed near-miss field is thin, not the foundation.

5. Retrieval

"retrievable in my head means what information passed through that left footprints."

Ruling: retrieval is trace-following, not lookup. What has passed through the system leaves footprints; retrieval traverses them. Consequence: the instrument gets (at least) two retrieval modes, deliberately different in kind — trace-based (footprint field, history-dependent, riverbed-shaped: this is delta/riverbed's machinery re-entering as a component under external observation) and fingerprint-based (WL/spectral, ahistorical). Their disagreement is data: what trace retrieval finds that fingerprints miss measures the instrument's history; the reverse measures structure the instrument hasn't lived through. The §64 basis worry resolves: the trace field is explicitly subjective state, never claimed as a neutral index.

The unification (engineer's observation, for the record)

Answers 2, 3 and 5 are one answer: dents, taste, footprints — the instrument's history of exposure is simultaneously its memory, its weighting, and its retrieval structure. That is riverbed's thesis ("weight = navigational salience given accumulated overlap") stated three times in three vocabularies, which is itself a small invariance-under- rephrasing datum about the researcher's model. The design accepts it: this instrument is not a neutral observer but a subject with auditable history — observer-dependence (§40) embraced at day one, accountable through provenance, perturbation, critics, and the near-miss field.
