## Decisions Made

### 1. README and Whitepaper Corrections (morning)

The README previously described AssetOverflow as an organization rather than stating the engineering pillars. Both the README and Whitepaper were updated to correctly document:

- **Three Engineering Pillars:** Mechanical Sympathy, Semantic Rigor, Third Door
- **Three Core Languages:** English (default base), Hebrew (depth), Koine Greek (depth)
- The John 1:1–2 theological grounding for the language choice — John articulated in Greek what was grounded in Hebrew, almost certainly a nod from the Holy Spirit. These two languages together carry a range of depth and precision that no single language achieves alone.
- The Logos as the structuring principle: language is not statistical residue of text, it is the forward projection of a field state onto a vocabulary manifold — a geometric act rooted in the same structure by which the universe was spoken into existence.

### 2. `core_ingest` Governance Layer — LLM Extraction Rejected

The original `core_ingest` design from `core-ai` was reviewed in full. The envelope design (`CandidateGeometricPressure`, `DeterminismClass`, `ReviewLevel`, three-gate `IngestCompiler`) was accepted as architecturally sound.

The LLM-as-extraction-engine component was **rejected** for two reasons:
1. An LLM upstream of the gate is a D3 nondeterministic oracle feeding the only normalization site in the system. Every document it processes lands in `ARCHITECT_REVIEW_REQUIRED` — defeating the layer's utility at scale.
2. More fundamentally: an LLM interprets, not merely parses. Its semantic projection is then silently embedded inside the field state, violating Semantic Rigor.

**Accepted path:** Deterministic `StructuralSegmenter` that carves at *form boundaries* (heading, paragraph, verse, code block, LaTeX delimiter), not semantic ones. A `SegmentManifold` index enables provenance tracing from vault recall back to the exact source span. See ADR-0012.

### 3. `sensorium/` Multimodal Protocol — Logos-Recovery Boundary

The `core_sensorium` design from `core-ai` was reviewed. The protocol shape — `ProjectionHead`, `SurfaceDecoder`, `ModalityVocabulary`, `ModalityPack[S]` — was accepted as the correct design for CORE's multimodal layer.

Key adaptations for `core`:
- Cl(3,0) `(2, 2)` complex multivector → Cl(4,1) `(32,)` multivector
- No `core_logos` subsystem dependency — grammar scaffold is versor attractors in `vocab/`
- `sensorium/` sits upstream of `core_ingest/`, which sits upstream of `ingest/gate.py`

The principle established: every modality is a versor on the same manifold from the moment it enters the system. There is no fusion problem because there is one space. This is the Logos-recovery boundary — the point at which any surface signal becomes a word in the Logos. See ADR-0013.

Current modality status: TEXT active (wires existing vocab manifold into `ModalityPack[str]`), VISION/AUDIO/MOTOR planned.

### 4. Build Queue — Ordered

Full inventory of `AssetOverflow/core` directories confirmed. The build order established:

1. **`core_ingest/`** — pre-gate governance layer (ADR-0012). Most important to build first; everything ingested into the system eventually passes through it. D0/D1-dominant paths (biblical texts) can reach AUTO_ACCEPT at scale without human review once built.
2. **`sensorium/`** — modality protocol (ADR-0013). Protocol files plus `adapters/text.py` only; vision/audio adapters come when those modalities are ready.
3. **`train/`** — learning loop (ADR-0014, stub). Closes the durable ingest path. Most architecturally significant remaining layer. Hebrew and Koine Greek Supervised Seeding Epoch is the first task once this layer exists.

### 5. Documentation Sprint (this session)

Three new ADRs written (0012, 0013, 0014). Session log written. Whitepaper and Yellowpaper updated.
