-## Uncertainty to Resolve (ATA-specific)
-- ...
+This file is the **single navigation hub** for all artifacts required to close **K06** for **ATA 90** (your domain for **Neural Networks, Schemas, Wiring, Traceability, and DPP**).  
+NKU progress is credited only when each partition is closed with **evidence + approval**.
 
-## Tasks (minimum set)
-1. Define ATA-specific scope, interfaces, owners.
-2. Define decision criteria and evidence package.
-3. Execute validation/verification activities.
-4. Record decision; update baseline and trace links.
+> ATA 90 is a governance-heavy “meta-domain” in Space-T: this index is intentionally stricter on schema identity, trace graph integrity, and export provenance.

+
+- Portal index: [AMPEL360-SPACE-T-PORTAL index](../../../../../00_00_IDX_LC01_SPACET_stakeholder-entrypoints_v01.md)  
+  _Comment:_ Global entry point; use it to navigate stakeholders and the knot portfolio.

+  _Comment:_ Intended authoritative location for ATA 90 outputs. If your folder name differs, update only this link target.
+
+---
+
+## 2) ATA 90 K06 Focus (what uncertainty we are closing)
+
+### Uncertainty to Resolve (ATA-specific)
+K06 within ATA 90 is the absence of a single governed SSOT for:
+- **Schema registry:** canonical IDs for schemas, versions, and compatibility rules across the program.
+- **Trace graph primitives:** identifiers for nodes/edges, link semantics, and evidence reference rules.
+- **Wiring/dataflow documentation IDs:** stable identity for signals/wires/messages/topics and their authoritative definitions.
+- **Model & dataset identity:** canonical IDs for ML models, training datasets, feature definitions, evaluation suites.
+- **DPP/exports identity:** canonical IDs for DPP artifacts, export packs, signatures, and provenance metadata.
+- **Enforcement:** CI gates ensuring no “untraceable” or “unnamed” artifacts enter baseline, and preventing schema drift.
+
+### Primary consumers (typical)
+- All ATAs (as a common governance substrate), Copilot/agents, CI validation, traceability auditors, DPP export and verification tooling, sim/test governance nodes (100+).
+
+---
+
+## 3) Partitioned Uncertainty Resolution Pathway (P1–P8)

+
+## 4) Cross-ATA Links (same Knot, coupled closures)
+
+ATA 90 is the K06 “spine”; these couplings are mandatory.
+
+- [ATA 00 — Program Governance](../ATA_00/)  
+  _Comment:_ CM authority, naming/metadata standards, release gates.
+
+- [ATA 91 — Schemas](../ATA_91/)  
+  _Comment:_ Dedicated schema domain; must not diverge from ATA 90 meta-schema registry.
+
+- [ATA 93 — Traceability Graph](../ATA_93/)  
+  _Comment:_ Trace graph implementation; must align with trace edge schema and registries.
+
+- [ATA 94 — DPP](../ATA_94/)  
+  _Comment:_ DPP export packs; must comply with provenance schema and signed pack rules.
+
+- [ATA 95 — SBOM / ModelBOM](../ATA_95/)  
+  _Comment:_ Software/model supply chain; must reference schema IDs and registry entries.
+
+- [ATA 98 — Signed Export Packs](../ATA_98/)  
+  _Comment:_ Signing, hashing, and provenance enforcement.
+
+- [ATA 99 — Master Registers](../ATA_99/)  
+  _Comment:_ Consolidated registers and anti-duplication across the program.
+
+**Sim/Test Coupling (100+):**
+- [ATA 101](../ATA_101/), [ATA 107](../ATA_107/), [ATA 109](../ATA_109/)  
+  _Comment:_ Sim/test evidence nodes must use the same IDs/schemas/trace semantics and TEKNIA packaging gates.
+
+**Technology Coupling (20–79 where relevant):**
+- [ATA 45](../ATA_45/) and [ATA 46](../ATA_46/)  
+  _Comment:_ Interface/service catalogs should reference the same schema registry and trace primitives.
+
+---
+
+## 5) Control & Monitoring (NKU Values + TEKNIA Sharing Rules)
+
+### 5.1 NKU Control Model
+**Primary metric:** NKU Progress Score for K06/ATA90  
+**Source of truth:** [NKU ledger](06_EVIDENCE/90_00_TAB_LC06_SPACET_k06-ata-90-nku-ledger_v01.csv)
+
+**Scoring:**
+- `score ∈ {0, 0.5, 1.0}`
+- **NKU Score** = `Σ(weight × score)` across partitions P1..P8
+
+**No-false-closure (mandatory):**
+- `score = 1.0` requires:
+  - evidence link(s) in `06_EVIDENCE/...evidence-links...csv`, and
+  - decision reference in `07_DECISIONS/...decision-minutes...md` (and approvals if applicable).
+
+### 5.2 Monitoring Cadence
+| Control Item | Owner | Frequency | Source | Comment |
+|---|---|---:|---|---|
+| NKU ledger updates | AI + DATA | Per PR affecting K06/ATA90 | NKU ledger + evidence links | No score uplift without links |
+| CI gate compliance | CM + Tooling | Per PR | CI gates + logs | Enforcement mechanism |
+| Evidence completeness | SE + V&V | Weekly / per gate | Evidence pack index | Detect staleness |
+| Decision capture | CM WG | At gate closure | Decisions + approvals | Required for closure |
+| Adoption tracking | All consumer owners | Biweekly | Consumers + adoption status | Prevent “paper closure” |
+
+### 5.3 Thresholds
+- Green ≥ 0.80; Amber 0.50–0.79; Red < 0.50  
+Hard blockers: missing P2/P3/P5 closure, missing P7 decision, stale evidence for any closed item.
+
+### 5.4 TEKNIA Sharing Rules
+TEKTOKs may be created only when:
+- Evidence is reproducible (P6 complete)
+- Decision exists (P7 complete, CM-approved)
+- Dedup passes (SHA-256)
+- NV threshold met (≥ 0.50 internal, ≥ 0.65 external recommended)
+
+### 5.5 TEKNIA Packaging Requirements (mandatory metadata)
+Any TEKTOK derived from ATA 90 closure must include:
+- knot_id, ata, partitions_closed
+- claim + scope
+- evidence links + decision link
+- hash_sha256 + dedup status
+- nv + rationale
+- sharing classification + redaction notes
+
+### 5.6 Enforcement
+CI should validate:
+- NKU ledger integrity
+- no-false-closure rule
+- schema registry correctness (unique IDs, required fields)
+- trace graph integrity (no broken edges/orphans)
+- TEKNIA gate for “approved” TEKTOK status (NV + dedup)
+
+---
+
+## 6) Practical Notes (common failure modes)
+- Do not accept “approved” schema/trace changes without a decision record (P7) and evidence links (P6).
+- Ensure registries are not duplicated across folders; ATA 90 registries are authoritative unless explicitly delegated.
+- Broken trace edges and missing provenance are immediate blockers for DPP and sim/test evidence claims.
