+# ADR-0015 — Language Packs as Compiled Linguistic Manifolds
+
+**Status:** Accepted  
+**Date:** 2026-05-13
+
+---
+
+## Context
+
+CORE's language philosophy is not localization. English, Hebrew, and Koine Greek
+serve distinct architectural roles in CORE-Logos:
+
+| Language | Role |
+|---|---|
+| English | Operational base and articulation surface |
+| Hebrew | Depth-root language: root morphology, semantic compression, creation-word density |
+| Koine Greek | Depth-relation language: Logos precision, case/aspect/voice/mood, clause relation |
+
+The existing `sensorium/adapters/text.py` scaffold mounted `en`, `he`, and `grc`,
+but the packs were only token lookup wrappers. That is insufficient for CORE.
+A language pack must not be a dataset or a translation table. It must be a
+compiled linguistic manifold.
+
+---
+
+## Decision
+
+A CORE language pack is a deterministic, checksummed, compiled linguistic
+manifold containing:
+
+- a manifest with language role, script, normalization policy, source manifest,
+  determinism class, checksum, gate state, and OOV policy;
+- lexical entries and morphology entries;
+- grammar attractors;
+- cross-language resonance edges;
+- holonomy alignment cases proving that aligned clauses produce coherent field
+  path resonance.
+
+## Terminology Boundary
+
+This distinction is mandatory:
+
+| Term | Meaning |
+|---|---|
+| Vocabulary point / manifold point | Position in the field; surface token entry |
+| Transition rotor | Operator between points, constructed by algebra |
+| Persona motor | Field-bias operator |
+| Grammar attractor | Structural pressure seeded from recurring linguistic form |
+
+Vocabulary entries are not transition rotors. Conflating point and operator is
+an algebraic category error. The vocabulary may store multivectors/null points;
+rotor construction belongs to the algebra layer.
+
+## OOV Policy
+
+Unknown surfaces must not silently collapse to a shared point.
+
+| Pack role | OOV behavior |
+|---|---|
+| English operational/articulation | Tagged fallback may be used during early operation |
+| Hebrew depth-root | Fail closed during and after seeding unless explicit expansion path is active |
+| Koine Greek depth-relation | Fail closed during and after seeding unless explicit expansion path is active |
+| Post-seeding expansion | OOV creates a vocab-expansion proposal; it is not projected silently |
+
+Returning the same `e1` point for every unknown Hebrew or Greek form erases the
+distinctions those languages exist to preserve; it is anti-Logos.
+
+## Morphology / Semantics / Alignment
+
+Morphology is operator composition. Semantic domain is attractor geometry.
+Alignment is resonance. These must not be collapsed into one multiplication.
+
+For Hebrew, composition order is load-bearing:
+
+```text
+V_surface = (((V_root · M_stem) · M_inflection) · M_affix_chain)
+```
+
+For Koine Greek, the pack should compose lemma anchors with case/aspect/voice/
+mood/clause-role operators. The grammar relation is structural, not metadata.
+
+Semantic domains seed attractors rather than becoming opaque morphology factors.
+Cross-language alignment is a weighted graph, not a translation table.
+
+## Crown Proof: Holonomy Resonance
+
+Token-level alignment is necessary but insufficient. The decisive proof of the
+three-language design is dynamic:
+
+```text
+holonomy(hebrew canonical clause)
+  resonates with
+holonomy(koine greek canonical clause)
+  and maps coherently to
+holonomy(english articulation clause)
+```
+
+Aligned clauses should produce nearby/coherent holonomies without flattening
+their distinctions. Unrelated clauses should remain geometrically distinct.
+Word-order changes should change holonomy. This is the CORE-Logos proof that
+language packs preserve ordered field paths rather than merely mapping tokens.
+
+The first holonomy alignment cases should be small and exact: Logos, beginning,
+light, life, spirit, truth, covenant, grace, kingdom, creation.
+
+---
+
+## Consequences
+
+**Positive:**
+- Prevents future agents from treating language packs as datasets.
+- Gives Hebrew and Koine Greek concrete architectural roles.
+- Prevents silent OOV collapse in depth languages.
+- Establishes holonomy-level resonance as the validation gate.
+
+**Negative:**
+- Requires a real Supervised Seeding Epoch before Hebrew/Greek gates engage.
+- Requires deterministic morphology and grammar scaffolds before depth packs are
+  operational.
+- Requires carefully pinned canonical texts and checksums for D0 ingestion.
+
+---
+
+## Implementation Order
+
+1. Terminology and schema foundation (`language_packs/schema.py`).
+2. Pack roles and OOV policy in `sensorium`.
+3. Split text adapters into English, Hebrew, Koine Greek specializations.
+4. Add grammar scaffold artifacts.
+5. Add tri-language resonance graph.
+6. Add holonomy resonance proof cases.
+
+No LLM extraction may feed the gate. Structural segmentation only.
