+# ADR-0128 — `en_numerics_v1` Pack
+
+**Status:** Proposed (scope-only; sibling to ADR-0127)
+**Date:** 2026-05-23
+**Author:** CORE agents + reviewers
+**Depends on:**
+- ADR-0126 (candidate-graph parser + round-trip filter)
+- ADR-0127 (`en_units_v1` — units pack, cross-referenced for
+  shared symbol/affix table)
+**Supersedes:** none
+**Sibling:** ADR-0127. Both packs are jointly required for the
+units-aware candidate-graph parser to produce a fair empirical
+result on the GSM8K-math lane. Either pack failing ratification
+independently blocks the joint exit gate.
+
+---
+
+## Context
+
+ADR-0127 introduces `en_units_v1` (dimensions, units, conversions,
+containers, rate connectors). That pack handles the *physical /
+economic* substrate. It does NOT handle the *linguistic forms* a
+quantity can take in English math word problems:
+
+- Cardinal number words ("seventeen", "two hundred and fifty")
+- Ordinal words ("third", "twentieth")
+- Fractions as words ("two-thirds", "a quarter") and as symbols
+  (`½`, `¾`)
+- Multiplier words ("twice", "triple", "half")
+- Quantifiers ("all", "some", "each", "every", "many", "few")
+- Comparison anchors ("more", "fewer", "less", "additional")
+- Numeric format strings ("1,000", "1.5", "1/2", "75%")
+
+Today these are scattered:
+- `WORD_NUMBERS` table hard-coded in `generate/math_roundtrip.py`
+  (one through twelve only)
+- `_COMPARE_VERB` / comparison anchors hard-coded in
+  `generate/math_parser.py`
+- Fraction handling absent
+- Percentage handling absent
+- Multi-digit number-word parsing ("two hundred") absent
+
+The GSM8K train sample shows the cost: e.g., "Half of the kids
+are going to soccer camp" (refused — `half` not handled),
+"3/4 of its temperature" (refused — `3/4` not recognized as
+fractional form). These are unrecognized *quantity forms*, not
+unrecognized *units*; they sit on a different lexical axis from
+ADR-0127's substrate.
+
+A units pack without a numerics pack solves "5 feet + 8 inches"
+but still refuses "half a foot." Both packs are needed for the
+architecture to get a fair empirical reading on the train sample.
+
+---
+
+## Decision
+
+Add a `language_packs/data/en_numerics_v1/` ratified semantic pack
+that exhaustively encodes the English linguistic forms of
+quantities. Parser changes are minimal — most pack content
+replaces today's scattered hard-coded tables with ratified
+lookups.
+
+### Pack content (`en_numerics_v1`) — EXHAUSTIVE SCOPE
+
+Structure mirrors `en_arithmetic_v1` / `en_units_v1`:
+`lexicon.jsonl` + `manifest.json` + `glosses.jsonl` +
+`.mastery_report.json`.
+
+**Cardinal number words** (entry_id prefix `en-num-card-`):
+
+EXHAUSTIVE for grade-school range:
+
+- `zero` through `twenty` (21 entries)
+- Tens: `thirty`, `forty`, `fifty`, `sixty`, `seventy`, `eighty`,
+  `ninety` (7 entries)
+- Compound rule: `<tens-word>-<unit-word>` (e.g., "twenty-one",
+  "ninety-nine") — structural composition, not enumerated
+- `hundred`, `thousand`, `million`, `billion` (4 entries)
+- Compound rule: `<N> hundred [and <M>]`, `<N> thousand
+  [<conjunction> <M>]` — structural composition
+
+Each entry carries `surface`, `numeric_value` (int), `morphology`
+(`cardinal`).
+
+**Ordinal number words** (entry_id prefix `en-num-ord-`):
+
+EXHAUSTIVE for grade-school range (1st–31st covers most
+calendar / position references in word problems):
+
+- `first` through `tenth` (10 entries — irregular morphology)
+- Suffix rule: `<cardinal>th` for 11–31 (eleventh, twelfth,
+  thirteenth, …, thirty-first) — structural composition with
+  spelling-irregularity table (`fifth` not `fiveth`, `eighth` not
+  `eightth`, `twelfth` not `twelveth`, etc.)
+- `twentieth`, `thirtieth`, `hundredth`, `thousandth` (4 entries)
+
+Each entry carries `surface`, `position` (int), `morphology`
+(`ordinal`).
+
+**Fraction words** (entry_id prefix `en-num-frac-`):
+
+- Named fractions: `half` (½), `third` (⅓), `quarter` (¼),
+  `fifth` (⅕), `sixth` (⅙), `seventh` (⅐), `eighth` (⅛),
+  `ninth` (⅑), `tenth` (⅒), `sixteenth` (¹/₁₆) — ~10 entries
+- Compound rule: `<cardinal>/<ordinal-as-denominator>` (e.g.,
+  "two-thirds", "three-quarters") — structural composition
+- Article-bound: `a half`, `a quarter`, `a third` resolve to
+  the same numeric value as the bare form
+- **Symbol cross-link** to `en_units_v1` symbol table for `½`,
+  `¼`, `¾`, `⅓`, `⅔`, `⅛`, `⅜`, `⅝`, `⅞`
+
+Each entry carries `surface`, `numerator` (int), `denominator`
+(int), `decimal_value` (float — `1/3 = 0.333…` etc.),
+`morphology` (`fraction`).
+
+**Multiplier words** (entry_id prefix `en-num-mult-`) — closed
+set:
+
+`double` (×2), `triple` (×3), `quadruple` (×4), `quintuple` (×5),
+`twice` (×2), `thrice` (×3), `half` (×0.5 — also a fraction
+word; both entries cross-reference). Plus structural rule
+`N times` for arbitrary integer multipliers.
+
+**Quantifiers** (entry_id prefix `en-num-quant-`) — closed set:
+
+`all`, `none`, `some`, `both`, `each`, `every`, `many`, `few`,
+`several`, `most`, `any`, `no`, `single`.
+
+Each declares its `semantic_type`: `total`, `empty`, `partial`,
+`paired`, `distributive`, `indefinite`. The parser uses this to
+decide whether the quantifier yields a determinate value
+(`both = 2`, `single = 1`) or is undeterminate and triggers
+refusal (`some`, `many`, `few` — refuse rather than guess; this
+preserves `wrong == 0`).
+
+**Comparison anchors** (entry_id prefix `en-num-compare-`):
+
+Migrated from `generate/math_roundtrip.py`'s hard-coded
+`COMPARE_ADDITIVE_ANCHORS` / `COMPARE_MULTIPLICATIVE_ANCHORS`.
+
+- Additive: `more`, `fewer`, `less`, `additional`, `extra`,
+  `missing`, `remaining`
+- Multiplicative: `twice`, `thrice`, `times`, `half`, `double`,
+  `triple`, `quadruple`, `third`, `quarter`
+
+Each cross-references its multiplier or fraction entry where
+applicable (avoiding duplicate truth).
+
+**Number formats** (entry_id prefix `en-num-format-`) —
+structural rules, not enumeration:
+
+- Digit groups: `1,000` (US thousand separator), `10,000`,
+  `1,000,000` — `(\d{1,3})(?:,\d{3})+` → strip commas, parse as int
+- Decimals: `1.5`, `3.14`, `0.25` — `\d+\.\d+` → parse as float
+- Slash-fractions: `1/2`, `3/4`, `7/8` — `(\d+)/(\d+)` →
+  parse as `Fraction`
+- Mixed numbers: `1 1/2`, `2 3/4` — `(\d+) (\d+)/(\d+)` →
+  `whole + numerator/denominator`
+- Percentages: `75%`, `1.5%` — `\d+(?:\.\d+)?%` → divide by 100
+- Negative numbers: `-3`, `-0.5` — leading minus (rarely in
+  grade-school but cheap to include)
+
+Each format rule declares its regex pattern, `parser_function`
+(by name), and `output_type` (`int`, `float`, `Fraction`).
+
+### Cross-references with `en_units_v1`
+
+- Fraction symbols `½`, `¼`, `¾`, etc. appear in both packs.
+  Single source of truth lives in `en_numerics_v1`;
+  `en_units_v1` symbol-affix table contains a *reference* entry
+  pointing to the numerics pack via `cross_pack_id`. Ratification
+  cross-pack consistency check (see ADR-0127 ratification
+  invariants and below) verifies the references resolve.
+- Percentage (`%`) cross-references between packs because it's
+  both a numeric format and a dimensionless modifier.
+- Multipliers (`double`, `twice`) cross-reference because they
+  also appear as comparison anchors in `en_units_v1`'s parser-
+  consumed register.
+
+### Ratification invariants (`en_numerics_v1`-specific)
+
+1. **Cardinal exhaustiveness** — every English cardinal 0..20,
+   every "tens" form, every magnitude word
+   (hundred/thousand/million) present.
+2. **Ordinal exhaustiveness** — every English ordinal 1st..31st
+   present (covers month days + most grade-school position
+   references).
+3. **Fraction exhaustiveness** — every named fraction 1/2 through
+   1/10 present + the irregular set (sixteenth, thirty-second).
+4. **Cross-pack consistency** — every fraction-symbol entry in
+   `en_units_v1` resolves to a fraction entry in
+   `en_numerics_v1`. Verified by joint pack-mount ratification.
+5. **Quantifier semantic-type completeness** — every quantifier
+   lemma carries a `semantic_type` from the closed set
+   `{total, empty, partial, paired, distributive, indefinite}`.
+6. **Format regex test corpus** — each format rule has a
+   minimum of 10 positive + 10 negative test strings in
+   `tests/test_adr_0128_numeric_formats.py`. Format ambiguity
+   (e.g., `1.000` could be `1` or `1000`) is *refused* per
+   `wrong == 0`, not guessed.
+
+### Parser integration
+
+1. **`generate/math_roundtrip.py`** — replace hard-coded
+   `WORD_NUMBERS` and `COMPARE_*_ANCHORS` tables with calls into
+   `en_numerics_v1` loader. Behavior preserved (current entries
+   are a subset); future extensions land in the pack, not the
+   source.
+
+2. **`generate/math_candidate_parser.py`** — new value-token
+   normalization helper `normalize_value_token(token) -> Quantity
+   | Fraction | None` that consults `en_numerics_v1` format
+   rules. Handles "two-thirds" → `Fraction(2,3)`, `75%` → `0.75`,
+   `1,500` → `1500`, etc.
+
+3. **Round-trip filter (`roundtrip_admissible`)** — the existing
+   `_value_grounds` helper is extended to ground word-forms via
+   the numerics pack loader (current hard-coded `WORD_NUMBERS`
+   capped at "twelve" widens to the full cardinal table).
+
+4. **Quantifier-driven refusal** — when a candidate's value-token
+   resolves to an `indefinite` quantifier (`some`, `many`, `few`),
+   the parser emits NO candidate for that sentence. Empty list →
+   refusal at decision rule. Preserves `wrong == 0`.
+
+### What ADR-0128 explicitly does NOT do
+
+- Does NOT replace `en_units_v1`. The packs are siblings.
+- Does NOT introduce new operation kinds. ADR-0126 + 0122 cover
+  the operation grammar; this pack supplies value-token forms.
+- Does NOT model number-system alternates (Roman numerals,
+  Chinese numerals, etc.) — out of scope for English math
+  problems.
+- Does NOT model implicit numbers ("a dozen" / "a few") as
+  determinate values — `a dozen = 12` is encoded via the
+  container's `default_size` (ADR-0127's container entry, not
+  here); `a few` is `indefinite` and triggers refusal.
+- Does NOT add new exit gates. Joint exit criterion with
+  ADR-0127 (re-run train sample with both packs mounted).
+

+
+## Invariants preserved / added
+
+| Invariant | Preserved or added | How |
+|-----------|--------------------|-----|
+| `wrong == 0` | Preserved | Indefinite quantifiers trigger refusal; format ambiguity triggers refusal |
+| `trace_hash` byte-equality | Preserved | Pack lookup is deterministic |
+| Pack-binding (ADR-0114a #10) | Reinforced | Value-token resolution cites `en-num-*` entry_ids in `SolutionTrace.provenance` |
+| Round-trip admissibility | Strengthened | Word-form numbers ground via pack lookup, not regex enumeration |
+| Replay equivalence | Preserved | Same pack version → same lookup result |
+| `versor_condition(F) < 1e-6` | Untouched | No runtime field changes |
+| Manifest checksum SHA-256 of bytes-on-disk | Required | Mastery report self-seals |
+
+## Exit criterion
+
+**Joint with ADR-0127** — both packs ratified, both mounted,
+re-run train sample:
+
+```
+correct >= 10 / 50  on evals/gsm8k_math/train_sample/v1/cases.jsonl
+wrong  == 0
+```
+
+**If passed:** run sealed holdout once, freeze in ADR-0127/0128
+joint results.
+
+**If missed:** **Path-B trigger** — full deterministic design
+(candidate-graph + units + numerics) failed to move GSM8K.
+Demote benchmark, re-target math expert promotion.
+
+---
+
+## Alternatives considered
+
+### A. Fold numerics into `en_units_v1` as one big pack.
+Rejected per ADR-0127 discussion: domain-distinct lexicons,
+risk-isolation, future i18n composability.
+
+### B. Keep hard-coded tables in `math_roundtrip.py` / `math_parser.py`.
+Rejected — violates pack-binding (ADR-0114a #10); future
+language packs (Spanish, German) would have to duplicate the
+hard-coded tables; ratification is impossible.
+
+### C. Use a third-party number-parsing library (`word2number`,
+`num2words`, etc.). Rejected — same opacity / non-auditability
+critique as ADR-0127 alt B.
+
+### D. Ship only cardinals + fractions; defer quantifiers /
+ordinals / formats. Rejected — quantifiers (`half`, `some`) are
+*specifically* what the GSM8K train sample refuses on. Partial
+pack delivers partial empirical signal — same trap ADR-0127
+addresses re: scope mismatch.
