## P.3 Protocol Cross-References

The protocol defined here carries the data formats from Phase 1 and the API
operations from Phase 2 across trust boundaries. Phase 4 describes how the
protocol composes with adjacent infrastructure.

### P.3.1 Transport Bindings

| Binding | Default Port | Use |
|---------|-------------:|-----|
| HTTP/2 + TLS 1.3 | 443 | Public, request-response |
| HTTP/3 (QUIC) | 443 | Mobile, lossy networks |
| gRPC | 443 | Service-to-service |
| MQTT 5.0 | 8883 | Constrained / IoT devices |
| AMQP 0-9-1 | 5671 | Backplane / event streams |

### P.3.2 Message Envelope

Every protocol message carries a small envelope independent of payload:

```
+----------------+------------------+--------------------+
| message_id     | UUIDv4           | RFC 4122           |
| trace_id       | 16-byte hex      | W3C Trace Context  |
| span_id        | 8-byte hex       | W3C Trace Context  |
| origin_node    | DNS name or NIN  | RFC 1035           |
| issued_at      | RFC 3339         | UTC required       |
| ttl_seconds    | uint32           | 0 = no expiry      |
| content_type   | media type       | RFC 6838           |
| body           | opaque bytes     | per content_type   |
+----------------+------------------+--------------------+
```

### P.3.3 Reliability Model

The protocol provides at-least-once delivery by default. Receivers
deduplicate by `message_id`. Exactly-once semantics are achieved when both
peers participate in the idempotency contract from Phase 2 §P.2.3.

### P.3.4 Backpressure

Senders MUST honour HTTP `Retry-After`, gRPC `RESOURCE_EXHAUSTED`, or MQTT
flow-control packets. The recommended back-off is full jitter exponential with
cap 30 s and cumulative cap 5 min.

## Appendix · Common WIA Standard Provisions

> The following provisions apply to every WIA standard and are kept in sync
> across the WIA-Standards corpus. Standard-specific deviations, where they
> exist, are listed in the standard's normative body.

### A. Conformance & Compliance

#### A.1 Conformance Levels

WIA-Standards defines four conformance levels:

| Level | Required | Description |
|-------|----------|-------------|
| L1 — Format | Phase 1 | Implementation produces and consumes the canonical data format losslessly |
| L2 — Interface | Phase 1 + 2 | Implementation exposes the API surface with required behaviour |
| L3 — Protocol | Phase 1 + 2 + 3 | Implementation interoperates over at least one normative transport binding |
| L4 — Integration | All Phases | Implementation passes the conformance test suite end-to-end in a production-shaped deployment |

Conformance claims MUST cite the level and the version of the standard
against which the claim is made (e.g. "L3 conformant against v1.0").

#### A.2 Compliance Verification

The conformance test suite is published alongside this standard at
`/cli/conformance/` and `/api/conformance/`. Implementations claiming
L2 or higher MUST publish their test report. Independent re-tests are
encouraged; the WIA Working Group accepts third-party verification reports
under the policy in §E.

### B. Security Considerations

#### B.1 Threat Model

Implementers SHOULD apply STRIDE analysis covering: spoofing of identity,
tampering with messages or stored state, repudiation of operations,
information disclosure, denial of service, and elevation of privilege.

| Threat | Default Control | Where Strengthened |
|--------|-----------------|--------------------|
| Spoofing | Mutual TLS or signed tokens | Phase 3 §P.3 |
| Tampering | TLS in transit, AEAD at rest | Phase 1 §P.1 |
| Repudiation | Append-only audit log with notarization | Phase 4 §P.4 |
| Disclosure | Field-level encryption for PII / secrets | Phase 1 §P.1 |
| DoS | Rate limit per principal & global circuit breaker | Phase 2 §P.2 |
| EoP | Least-privilege RBAC + scoped tokens | Phase 2 §P.2 |

#### B.2 Cryptographic Suites

Mandatory: TLS 1.3 with AEAD ciphers (AES-128-GCM, AES-256-GCM,
CHACHA20-POLY1305). Forbidden: TLS 1.0, TLS 1.1, RC4, MD5, SHA-1 for
signatures, RSA below 2048 bits, ECDSA on curves smaller than P-256.

Post-quantum migration: implementations SHOULD adopt hybrid key
exchange combining a classical primitive with ML-KEM (FIPS 203) once a
profile is published; signature migration to ML-DSA (FIPS 204) is
expected within the L4 conformance window of v2.0.

#### B.3 Audit Requirements

L3 and L4 implementations MUST log: (a) every authentication decision,
(b) every authorization decision, (c) every state-changing operation,
(d) every export of data outside its sovereignty boundary. Logs are
write-once for at least 1 year and 90 days indexed for incident search.

### C. Versioning & Lifecycle

Versions follow Semantic Versioning 2.0.0 (MAJOR.MINOR.PATCH).

| Phase | Duration | Conformance Status |
|-------|---------:|-------------------|
| Draft | until ratification | Non-binding |
| Active | indefinite | Binding for new deployments |
| Maintenance | 24 months from successor's Active date | Binding for existing deployments |
| Retired | indefinite | Non-binding; conformance claims rescinded |

Deprecation MUST be announced at least one minor version before a feature
is removed in a major version.

### D. Internationalization & Accessibility

Implementations SHOULD support locale negotiation via the
`Accept-Language` header (RFC 4647). Date, time, number, and currency
formatting follow CLDR. User-facing surfaces MUST satisfy WCAG 2.1 AA at
minimum and SHOULD progress towards WCAG 2.2 AA. Right-to-left scripts
(Arabic, Hebrew, Persian, Urdu) and East-Asian wide characters MUST be
laid out correctly without line-breaking heuristics that split graphemes.

### E. Governance & IP Policy

This standard is maintained by the WIA Working Group under the WIA
governance charter. Editorial changes are merged via pull request. Normative
changes require working-group consensus and a 30-day public review.
Contributions are accepted under the Apache License 2.0 with explicit
patent grant. Members participate under the WIA Patent Policy,
which requires royalty-free licensing of any essential claim necessary
to implement a normative requirement.

### F. Normative References

The following references are normative; implementations MUST satisfy
the cited clauses:

- ISO/IEC 27001:2022 — Information security management systems
- ISO/IEC 27017:2015 — Cloud-services security controls
- ISO/IEC 27701:2019 — Privacy information management
