-## Uncertainty to Resolve (ATA-specific)
-- ...
+This file is the **single navigation hub** for all artifacts required to close **K06** for **ATA 91** (your domain for **Schemas and Canonical Data Models**).  
+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 91 is the canonical “schema engine room” for Space-T. This index is intentionally strict on schema identity, versioning, compatibility, and CI validation.

+
+---
+
+## 2) ATA 91 K06 Focus (what uncertainty we are closing)
+
+### Uncertainty to Resolve (ATA-specific)
+K06 within ATA 91 is the absence of a single governed SSOT for:
+- **Schema registry:** canonical IDs, owners, lifecycle status, and discovery metadata for all schemas.
+- **Canonical data models:** shared definitions for entities/fields/enums used cross-ATA.
+- **Versioning and compatibility:** strict rules for breaking changes, deprecations, and migration guidance.
+- **Validation and tooling:** schema validation, linting, and packaging (CI gates).
+- **Publication and consumption:** deterministic export packs and references that downstream ATAs can rely on.
+- **Trace semantics alignment:** schemas must integrate with traceability primitives (ATA 93) and DPP packs (ATA 94).
+
+### Primary consumers (typical)
+- All ATAs (as schema consumers), traceability tooling, DPP export tooling, sim/test governance nodes (100+), and agent automation.
+
+---
+
+## 3) Partitioned Uncertainty Resolution Pathway (P1–P8)

+
+---
+
+## 5) Control & Monitoring (NKU Values + TEKNIA Sharing Rules)
+
+### 5.1 NKU Control Model
+**Primary metric:** NKU Progress Score for K06/ATA91  
+**Source of truth:** [NKU ledger](06_EVIDENCE/91_00_TAB_LC06_SPACET_k06-ata-91-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/ATA91 | 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 + Schema Authority | At gate closure | Decisions + approvals | Required for closure |
+| Adoption tracking | Consumer owners | Biweekly | Consumers + adoption status | Prevent shadow schemas |
+
+### 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:
+- schema validity + registry completeness
+- uniqueness of schema IDs and versions
+- versioning/breaking-change compliance
+- TEKNIA gate for “approved” TEKTOK status (NV + dedup)
+
+---
+
+## 6) Practical Notes (common failure modes)
+- Do not accept “approved” schema changes without a decision record (P7) and evidence links (P6).
+- Schema registry completeness is non-negotiable; missing entries are immediate CI failures.
+- Breaking schema changes must ship with migration guidance and deprecation policy adherence.
