-- ...
+This file is the **single navigation hub** for all artifacts required to close **K06** for **ATA 46** (Technology domain).  
+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.
+> Note: ATA 46 label/title may differ in your Space-T internal register. This index treats ATA 46 as a technology node focused on **information systems / data distribution / data services**, where SSOT, stable schemas, and identifier governance are critical. Update the ATA title in your master register if needed—this index remains valid.

+
+## 2) ATA 46 K06 Focus (what uncertainty we are closing)
+
+### Uncertainty to Resolve (ATA-specific)
+K06 within ATA 46 is the absence of a single governed SSOT for:
+- **Service identity:** canonical IDs for data services, APIs, endpoints, contracts, datasets, and routing rules.
+- **Semantic correctness:** stable schemas for service payloads, metadata, units, frames, validity, timing, QoS.
+- **Distribution rules:** canonical topic/routing/labeling rules, data retention policies, and access controls (as metadata).
+- **Publication and consumption:** machine-consumable exports for downstream ATAs/tools (integration, ops monitoring, sim/test).
+- **Enforcement:** CI gates preventing drift (duplicate IDs, unversioned schemas, undocumented breaking changes).
+
+### Primary consumers (typical)
+- Avionics/IMA runtime, communications/telemetry routing, ops dashboards, health monitoring, sim/test harnesses, traceability/DPP exports.
+
+---
+
+## 3) Partitioned Uncertainty Resolution Pathway (P1–P8)
+
+Each partition corresponds to a dedicated folder. **Do not credit closure** unless the partition’s “Done” definition is satisfied.

+
+## 5) Control & Monitoring (NKU Values + TEKNIA Sharing Rules)
+
+### 5.1 NKU Control Model
+**Primary metric:** NKU Progress Score for K06/ATA46  
+**Source of truth:** [NKU ledger](06_EVIDENCE/46_00_TAB_LC06_SPACET_k06-ata-46-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/ATA46 | 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 | Data Platform owners + OPS + SIM/TEST | Biweekly | Consumers + adoption status | Avoid “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 Enforcement
+CI should validate NKU ledger integrity and block false closure and “approved” TEKTOKs without NV+dedup compliance.
+
+---
+
+## 6) Practical Notes (common failure modes)
+- Do not accept “released service catalogs” without schema validation (P3) and CI enforcement (P5).
+- Do not credit NKU closure without decision minutes (P7) and an evidence pack (P6).
+- Treat routing/labeling semantics and QoS/timing metadata as priority risks; they break interoperability silently.
