-## Uncertainty to Resolve (ATA-specific)
-- ...
+This file is the **single navigation hub** for all artifacts required to close **K06** for **ATA 93** (your domain for **Traceability Graph and Evidence Link Semantics**).  
+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 93 is where K06 becomes operational: if trace edges are ambiguous or broken, K06 cannot be closed program-wide.

+
+---
+
+## 2) ATA 93 K06 Focus (what uncertainty we are closing)
+
+### Uncertainty to Resolve (ATA-specific)
+K06 within ATA 93 is the absence of a single governed SSOT for:
+- **Trace node identity:** canonical IDs for artifacts, requirements, hazards, tests, datasets, models, decisions.
+- **Trace edge semantics:** standardized edge types (e.g., *derives*, *verifies*, *mitigates*, *implements*, *depends-on*, *evidenced-by*).
+- **Evidence link rules:** how links point to files, commits, releases, signed packs; staleness detection rules.
+- **Graph integrity:** prevention of orphan nodes, broken edges, cycles (where prohibited), and duplicate identities.
+- **Publication:** deterministic export of trace graphs for audits, reviews, and DPP packs.
+- **Enforcement:** CI gates that block merges when trace integrity breaks.
+
+### Primary consumers (typical)
+- Configuration management, safety/certification evidence, DPP exports, CI validation, sim/test evidence nodes (100+), 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/ATA93  
+**Source of truth:** [NKU ledger](06_EVIDENCE/93_00_TAB_LC06_SPACET_k06-ata-93-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/ATA93 | NKU ledger + evidence links | No score uplift without links |
+| CI gate compliance | CM + Tooling | Per PR | CI gates + logs | Enforcement mechanism |
+| Graph integrity | Trace Authority + Tooling | Per PR + weekly sweep | CI outputs + integrity reports | Orphans/broken edges are blockers |
+| Evidence freshness | SE + V&V | Weekly / per gate | Evidence links register | Detect staleness |
+| Decision capture | CM WG + Trace Authority | At gate closure | Decisions + approvals | Required for closure |
+| Adoption tracking | Consumer owners | Biweekly | Consumers + adoption status | Prevent shadow traces |
+
+### 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:
+- trace graph schema compliance
+- link target validity (path/commit/tag/signed pack) and required metadata
+- graph integrity constraints (no broken edges/orphans)
+- TEKNIA gate for “approved” TEKTOK status (NV + dedup)
+
+---
+
+## 6) Practical Notes (common failure modes)
+- If a consumer cannot ingest the trace export deterministically, K06 cannot be considered closed.
+- Prefer signed export packs as evidence targets for released states; raw file paths drift.
+- Avoid ambiguous edge types; if a new edge type is needed, register it (P2) and define semantics (P3) before use.
