Elamur Groupantsworld-report-formatting
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
TSV and Markdown presentation.
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
rows_tsv/tale_md share cell for content; tale_md displays anchor only for none source, while TSV may display an anchor for either source.
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: Under delimiter-free metadata and CR-free content, rows_tsv emits sixteen columns and one line per row. This bound is invalid for unrestricted story/attribute/ex metadata.
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: Displayed text cannot recover whether spaces arose from tabs, newlines or original spaces; rounded two/three decimal scores have interval fibers, not unique real values.
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.
source-display
Subject: current bound source and this node's scope. Domain and observation: tale_md chooses state text with note versus not-in-state reason; only none source gets visible anchor fallback. Tests compare the none branch and numeric precision.
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.
empty-format
Subject: current bound source and this node's scope. Domain and observation: Empty TSV retains only its fixed header; empty tale_md retains title and table header. These outputs do not imply any evaluated question.
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.
