# Session Log — 2026-05-13
|
||
|
||
**Participants:** Joshua Shay, Perplexity
|
||
**Focus:** Ingest layer governance design, sensorium multimodal architecture, build queue ordering, documentation audit
|
||

|
||
|
||
## Summary
|
||
|
||
This session produced the three most significant architectural decisions since the Cl(3,0) → Cl(4,1) migration: the design of the `core_ingest/` governance layer (ADR-0012), the design of the `sensorium/` multimodal protocol layer (ADR-0013), and the constraints governing the future `train/` learning loop (ADR-0014).
|
||

|
||
|
||
## 1. README and Identity Corrections
|
||
|
||
The README previously had no identity — no engineering pillars, no language philosophy. It also contained a product description for AssetOverflow that doesn't belong in a technical repository.
|
||
|
||
**Changes committed:**
|
||
- Added the Three Engineering Pillars section: Mechanical Sympathy, Semantic Rigor, Third Door
|
||
- Added the Three Core Languages section: English (default base), Hebrew and Koine Greek (depth languages), with the full John 1:1–2 theological grounding
|
||
- Removed the AssetOverflow org description
|
||
- Updated `docs/Whitepaper.md` to correctly name and separate the Three Engineering Pillars from the Architecture Invariants
|

||
## 2. `core_ingest/` — The Ingest Governance Layer
|
||
|
||
**Original design reviewed:** `CandidateGeometricPressure` envelope, `DeterminismClass` taxonomy, `IngestCompiler` three-gate validation, `ReviewLevel` governance, `SegmentManifold` index, Rust hot-path for SHA-256/canonical JSON/lemma normalization.
|
||
|
||
**Key decision — LLM extraction rejected:**
|
||
The original `core_ingest` design used an LLM as the extraction engine for large documents. This was rejected on two grounds:
|
||
|
||
1. An LLM is a D3 nondeterministic oracle feeding the only normalization site in the system. Every extracted packet would land in `ARCHITECT_REVIEW_REQUIRED` territory, defeating utility at scale.
|
||
2. An LLM interprets, not parses. Its semantic projection is silently embedded in the field state, violating Semantic Rigor. The field owns semantic interpretation.
|
||
|
||
**Replacement:** A deterministic `StructuralSegmenter` that carves at form boundaries (headings, paragraph breaks, verse markers, code blocks, LaTeX delimiters). For Hebrew and Koine Greek, this is D0 by construction — canonical verse boundaries are fixed for centuries.
|
||
|
||
**What was kept from the original design:** The `CandidateGeometricPressure` envelope, content addressing via `pressure_id` and `semantic_key`, the three-gate compiler, the `DeterminismClass` taxonomy, `ReviewLevel` governance embedded as a type invariant, and the `SegmentManifold` reconstruction index.
|
||
|
||
See ADR-0012.

|
||
## 3. `sensorium/` — The Multimodal Protocol Layer
|
||
|
||
**Source:** The `core_sensorium` package in `AssetOverflow/core-ai` was reviewed directly. Its `protocol.py` described the `ProjectionHead` as the "Logos-recovery boundary" — confirming the architectural intuition that all modality inputs ultimately reduce to the Logos native to the system.
|
||
|
||
**Key claim:** All inputs boil down to the Logos. A visual scene, a Hebrew word, an audio waveform are all the same thing inside the field: a point on the conformal manifold. There is no multimodal fusion problem because there is nothing to fuse. One space.
|
||
|
||
**Translation from `core-ai` to `core`:**
|
||
- Cl(3,0) `(2, 2)` complex multivector → Cl(4,1) `(32,)` f32 array
|
||
- `core_logos.grammar_seed` dependency → `vocab/` versor attractors (no cross-subsystem import)
|
||
- Protocol shape (`ModalityPack`, `ProjectionHead`, `SurfaceDecoder`, `ModalityVocabulary`) preserved
|
||
|
||
**Placement in pipeline:** `sensorium/` sits upstream of `core_ingest/`. `ingest/gate.py` is unchanged. Adding a modality requires one adapter file and a registry entry — no existing layer is touched.
|
||
|
||
See ADR-0013.

|
||
## 4. Build Queue
|
||
|
||
Ordered by dependency and architectural risk:
|
||
|
||
1. **`core_ingest/`** — upstream of everything; build now while the system is small. `StructuralSegmenter`, `CandidateGeometricPressure`, three-gate `IngestCompiler`, `ReviewLevel`, `SegmentManifold`.
|
||
2. **`sensorium/`** — `protocol.py`, `registry.py`, `adapters/text.py` (text adapter only, wiring existing vocab manifold into `ModalityPack[str]`). Vision/audio adapters deferred until bootstrap corpora exist.
|
||
3. **`train/`** — the largest remaining build item. Requires `core_ingest/` to be complete and producing `LearningArtifact` objects. Rotor update law, vocab expansion protocol, and Supervised Seeding Epoch (Hebrew + Koine Greek D0 corpus).
|
||
4. **Tests for all three** — `tests/test_core_ingest.py`, `tests/test_sensorium_mount.py`, `tests/test_train_artifact_path.py`.
|
||
|

|
||
|
||
## 5. Documentation Audit
|
||
|
||
Full audit of `docs/` performed:
|
||
|
||
- **`docs/Whitepaper.md`** — already fully updated from a prior session. Sections VII–IX (pipeline, ingest governance, sensorium) are current. No changes needed.
|
||
- **`docs/Yellowpaper.md`** — already fully updated. Sections VI–VII (sensorium spec, `core_ingest` spec) are current. No changes needed.
|
||
- **`docs/decisions/README.md`** — ADRs 0012–0014 and `SESSION-2026-05-13` were already listed in the index (scaffolded in a prior session). The actual files did not yet exist. Created in this session.
|
||
- **ADR-0002** — marked as Archived / superseded by ADR-0012 in the README index.
