Elamur Groupantsworld-report-aggregation
The groupant beside world/src/report.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.
Facts
Implementation material. A Mova code model describes this code at one source revision: partial models, finite checks and their stated scope. It is not a reviewed general exposition, and its labels are shown as written, never raised.
Components
| component | label | where |
|---|---|---|
| approximant | partial source model | forward |
| ast | partial | ../syntax.json |
| composition | partial source model | composition |
| cost | partial source model | cost |
| descriptant | partial source model | epoch-memory |
| invariant | partial source model | invariant |
| tests | partial source model | checks |
Obernants
The typed relations around the forward model: the behaviour complement (what the code never does), the reverse reconstruction (every input compatible with an output) and specialised views.

Model text
Automated scoring adapter and aggregate report slices.
forward
eval_tale obtains state answer, anchor fallback and baseline then scores; Agg sums supplied r_slm/r_anchor/r_base and separately sums state-source r_slm. report folds rows into fixed attribute order plus ordered maps for explicitness/story/first-space intent. sample ranks eligible identities by salted wrapping FNV/finalizer. read_verdicts skips malformed rows, overwrites duplicate keys; manual_md averages only matched recognized-type rows.
invariant
For Agg built from add, 0<=answered<=n; zero denominators use max(1). Only source determines answered membership; score fields are trusted and may be inconsistent with source. Manual scores are trusted rather than masked when Src::None. Unknown attributes contribute to all totals but lack a displayed attribute slice.
cost
N rows and total text bytes L: aggregation O(N log G + L), formatting linear in emitted bytes, sampling scans N once per seven attributes and sorts each slice O(N log N) overall with repeated key allocation. Manual lookup O(N log V), verdict decoding O(L + V log V). eval_tale cost includes external answer/baseline/scoring dependencies; no measured speed claim.
composition
eval_tale masks nonstate automated r_slm to zero, but public Row can contain other scores; Agg does not repeat that mask.
epoch-memory
2026-10-30: first source-bound modeling epoch. Synthetic native fixtures only; no held-out tales, live parsers or annotators. CSV lost a quoted empty final record; a zero-length known section prevented decomposition progress. The repaired scanner retains quoted-field presence and decomposition ignores empty candidates. Report observations preserve existing permissive score/label semantics rather than silently enforcing a new measurement policy. Native finite evidence does not establish unrestricted correctness.
checks
Run cargo test -p world --lib report::wave9_models -- --test-threads=1. See the root sidecar evidence.md for repeated debug/release checks and compiled controls. Partial syntax excludes macro expansion and type/name resolution. No executable percentage approximant is claimed.
behavior-complement
Subject: current bound source and this node's scope. Domain and observation: For default/add histories state count cannot exceed total count. No absence claim covers manually constructed inconsistent Agg or nonfinite scores.
Status: source-derived partial relation, supported only where named finite fixtures apply. Assume successful allocations, fixed dependencies and bounded native inputs; external filesystem/answer-generation effects remain unknown. The relation describes one terminating call, not all process traces.
reverse-reconstruction
Subject: current bound source and this node's scope. Domain and observation: Sums/counts forget row identity and ordering; fixed all-state half-unit pair sum yields fibers [1,2,3,2,1] in the finite oracle.
Status: source-derived partial relation, supported only where named finite fixtures apply. Assume successful allocations, fixed dependencies and bounded native inputs; external filesystem/answer-generation effects remain unknown. The relation describes one terminating call, not all process traces.
denominators
Subject: current bound source and this node's scope. Domain and observation: All-row and answered-only ratios have distinct denominators; empty ratios use one. Native 216-case integer oracle tests arithmetic before and after formatting.
Status: source-derived partial relation, supported only where named finite fixtures apply. Assume successful allocations, fixed dependencies and bounded native inputs; external filesystem/answer-generation effects remain unknown. The relation describes one terminating call, not all process traces.
slice-loss
Subject: current bound source and this node's scope. Domain and observation: report omits the ? bucket from the type table while retaining it in all and other maps. Intent key is first substring before ASCII space, possibly empty; it is not a parsed intent enum.
Status: source-derived partial relation, supported only where named finite fixtures apply. Assume successful allocations, fixed dependencies and bounded native inputs; external filesystem/answer-generation effects remain unknown. The relation describes one terminating call, not all process traces.
