Riggs 1890 Verifier Loop

Spec and executable checker for the next Dakota1890 experiment: grammar rules compiled into executable checks, used as the RL environment that filters and labels synthetic data, growing the training surface to the ceiling of what is in the book — without ever promoting an unattested form to gold.

File	What it is
`SPEC.md`	The experiment spec: what already exists in lexgym, the delta, rule schema, admission test, arms, measures, compute shape
`checker.py`	Executable rule checker v0 (in-repo as `lexgym/rules.py`): alphabet, syllable shape, attestation, n/ŋ variants, stem-relation buckets. Runs as an audit against the published gold
`triage_unexplained_v0.parquet`	Checker v0's triage list (5,869 rows): unexplained, shape-violating and n/ŋ-variant inflected forms with entry ids, pages and source images

Live demo: HarleyCooper/riggs1890-rule-checker — paste a form, get the verdict.

Checker v0 audit results (2026-11-13, corrected)

Run against the published gold (HarleyCooper/riggs1890-lexicon-graph, config dakota_entries): 16,980 entries, 5,583 with inflected forms, 7,864 inflected-form instances, 0 alphabet violations (the extraction is fully pre-canonicalized).

Correction (2026-11-13, later): the first published run mislabeled the stem relation, naming it by string position instead of morphology — a form starting with the headword has material appended after the stem, which is a suffix (ahi → ahi-pi), and a form ending with the headword has material prepended before the stem, which is a prefix (ahi → wa-ahi). Codex review of Dakota1890 PR #166 caught it; the labels below, the parquet, and lexgym/rules.py are corrected. A shape-violation verdict was also added.

Verdict	Instances
attested-headword (form is itself a headword)	231
n/ŋ variant of an attested form	39
shape violation (unparsable hyphenated/accented form — extraction artifacts, e.g. `dimi-nishing`)	62
licensed-pending (prefix/suffix/contained relative to the family headword)	1,764
unexplained	5,768

Relation distribution over the 7,532 non-attested, non-violating instances — this is the Milestone 2 affix-inventory signal:

Relation	Count
prefix (material before the stem, e.g. `wa-`)	1,225
other (stem not contiguous in the form)	5,600
contained (infix)	483
suffix (material after the stem, e.g. `-pi`)	56
no-stem	168

Reading of the numbers: simple contiguity matching explains only ~23% of non-attested forms. The insertion probe in Dakota1890 (tools/verifier_loop/insertion_probe.py, 12 Nov 2026) does better: 17 edits learned from train families only — inserts wa (2,474×), ma, uŋ, ya, plus substitutions y→md (805×), ki→we — explain 73.6% of held-out-family forms (81.0% ignoring diacritics), against the spec's 60% coverage gate. And the same 17 edits build a median of 93 candidate forms per held-out headword: a rule can license a form but cannot choose it, so attestation must pick. The probe also found a probable extraction bug: 98 forms whose accented initial e was read as ć by the é→ć variant mapping in lexgym/orthography.py (written for headwords, applied to inflected forms) — not yet page-checked.

The three labels

attested — in the book, passes alphabet + shape. Gold, always.
licensed — rejected by no admitted rule, not attested. Training only in the licensed arm; never gold without a speaker or a second source.
rejected — breaks an admitted rule or the alphabet. Excluded; feeds back to the generator.

Relationship to existing artifacts

Extends HarleyCoops/Dakota1890 (lexgym/) — does not replace it. The reverse task (en_to_dak), two-witness gold, family splits and the lookup tool already exist there; the merged checker lives at lexgym/rules.py.
Labels against HarleyCooper/riggs1890-lexicon-graph.
The unverified control arm is priced against the Stoney-RL setup (HarleyCoops/Stoney-RL), where the model wrote the answers and the reward placeholder returned 0.0.
The question-surface contract ("vary the question, never the answer") is HarleyCoops/Cree1865's, already validated in its anchored-expansion run.
