# Domain Coverage
|
||
|
||
> Where each core principle applies across the domains. The complement to `principles-matrix.md`: the matrix maps domain → core; this maps core → domains.
|
||
|
||
## Core Principle Coverage
|
||
|
||
| Core Principle | Domains that derive from it | Count |
|
||
|----------------|---------------------------|-------|
|
||
| C1 Correctness | All 19 (v0.1: 11; v0.2: infrastructure-as-code, kubernetes; v0.3: gitops-operators, ai-ml, i18n, compliance; v0.4: edge, messaging) | Universal |
|
||
| C2 Clarity | v0.1: uiux, api, data, testing, observability, errors, documentation, devops; v0.2: infrastructure-as-code, kubernetes; v0.3: gitops-operators, ai-ml, i18n, compliance; v0.4: messaging | 16 |
|
||
| C3 Simplicity | v0.1: security, data, testing, performance, documentation, concurrency, devops; v0.2: infrastructure-as-code; v0.3: gitops-operators, i18n, compliance; v0.4: edge | 12 |
|
||
| C4 Locality | v0.1: testing, concurrency; v0.2: infrastructure-as-code, kubernetes; v0.3: gitops-operators, i18n; v0.4: edge, messaging | 8 |
|
||
| C5 Reversibility | v0.1: api, data, uiux, concurrency, devops; v0.2: infrastructure-as-code, kubernetes; v0.3: gitops-operators, ai-ml, i18n, compliance; v0.4: edge, messaging | 13 |
|
||
| C6 Composability | v0.1: api, security, observability, errors, documentation, concurrency; v0.2: infrastructure-as-code, kubernetes; v0.3: gitops-operators, ai-ml, i18n, compliance; v0.4: edge, messaging | 14 |
|
||
| C7 Observability | v0.1: api, data, testing, performance, observability, errors, devops; v0.2: infrastructure-as-code, kubernetes; v0.3: gitops-operators, ai-ml, i18n, compliance; v0.4: edge, messaging | 15 |
|
||
| C8 Economy | v0.1: security, testing, performance, observability, concurrency; v0.2: kubernetes; v0.3: gitops-operators, i18n, compliance; v0.4: edge, messaging | 11 |
|
||
|
||
## Interpretation
|
||
|
||
- **C1 Correctness** is universal — every domain derives from it. This confirms C1 as the floor.
|
||
- **C4 Locality** is the narrowest (2 domains: testing independence, concurrency boundaries). Locality is inherently domain-specific; not a gap.
|
||
- **C2 Clarity** and **C7 Observability** are the next-most-derived, confirming they are cross-cutting concerns.
|
||
- **C6 Composability** appears in 6 domains — it is most relevant where parts combine (api, errors, observability, documentation, concurrency) and least relevant where the unit is monolithic.

## Gaps and Notes
|
||
|
||
- No domain derives from only one C-rule. The minimum is 4 (UI/UX: C1, C2, C3, C5, C7 — actually 5). Every domain is multi-rooted.
|
||
- **Concurrency**, **Infrastructure as Code**, and **Kubernetes** are tied for the broadest derivation among v0.1/v0.2 platform domains (7 C-rules each) — these domains touch the most core concerns.
|
||
- **GitOps + Operators** and **i18n** are tied for the single broadest-derivation domain overall (8 C-rules each: C1–C8). GitOps adds C4 (pull-credential locality) alongside its source-of-truth/reconciliation/least-privilege derivation; i18n touches correctness, clarity, simplicity, locality, reversibility, composability, observability, and economy (expansion accommodation). This is consistent with both domains' cross-cutting nature.
|
||
- **UI/UX** and **API** are the most user-facing; they emphasize C2 (Clarity) heavily.
|
||
- **Security** is the only domain with explicit non-tradeable declarations; this promotes 8 of its rules to C1-equivalent per `core/conflict-resolution.md` §6.
|
||
- **v0.2 expansion:** C4 (Locality) grew from 2 to 4 domains (added infrastructure-as-code state locality, kubernetes namespace blast-radius). C6 (Composability) grew from 6 to 8. The two new domains are broad-derivation domains (7 C-rules each), consistent with Concurrency's breadth.
|
||
- **v0.3 expansion:** C3 (Simplicity) grew from 7 to 11 (added gitops-operators declarative simplicity, i18n flexible layout, compliance structural redaction). C4 (Locality) grew from 4 to 6 (added gitops-operators pull-credential locality, i18n resource/text-direction locality). C5 (Reversibility) grew from 7 to 11 (added all four v0.3 domains — gitops history, ai-ml reproducibility, i18n translation versioning, compliance append-only/retention). C6 (Composability) grew from 8 to 12. C7 (Observability) grew from 9 to 13 (added all four v0.3 domains — reconciliation, drift detection, format correctness, posture). C2 (Clarity) grew from 10 to 14. The v0.3 expansion broadens every non-universal C-rule's coverage, confirming the four new domains are cross-cutting and well-rooted.
|
||
- **v0.4 expansion:** C2 (Clarity) grew from 14 to 16 (added messaging P1/P2/P4 — contract clarity). C4 (Locality) grew from 6 to 8 (added edge P1/P8 geographic locality, messaging P7 partition locality). C5 (Reversibility) grew from 11 to 13 (added edge P2/P4/P7/P10 reconciliation + degradation, messaging P5/P8/P9 replay + evolution). C6 (Composability) grew from 12 to 14 (added edge P8 fleet composition, messaging P7/P9 partition + version composition). C7 (Observability) grew from 13 to 15 (added edge P10 partition-survivable telemetry, messaging P8/P10 durable-log + lag). C8 (Economy) grew from 9 to 11 (added edge P3/P9 constrained resources + trust, messaging P6 bounded backpressure). C3 (Simplicity) grew from 11 to 12 (added edge P6 explicit invalidation simplicity). Both v0.4 domains are broad-derivation (7 C-rules each), consistent with the v0.2/v0.3 precedent.
|
||
- **Languages Coverage (v0.4, D-066):** The 16 language-derived docs (4 languages × 4 docs) apply existing domain P-rules; they introduce no new matrix rows (D-063, D-066). The sub-table above is the verifiable aggregate — every derived doc traces to ≥1 domain P-rule (no orphans). Languages are an application lens, not a principle source. |
