Core System Architecture Part 150 — Anonymous Network Extension Developer Relations, Publisher Support, Documentation Governance, Compatibility Communication, Migration Guidance, Ecosystem Education & Privacy-Preserving Developer Success Architecture
SIAR — Secure, Local-First, Multi-Transport Communication Platform
Series: Core System Architecture
Part: 150
Status: Architecture specification
Primary language: Rust
Builds on: Core System Architecture Parts 65, 122–132, 147–149
Primary purpose: define SIAR's developer-relations and publisher-support architecture for documentation governance, compatibility communication, migration guidance, support workflows, developer education, reference implementations, change announcements, feedback intake, AI-assisted support, and privacy-preserving developer-success operations.
1. Purpose
A mature extension ecosystem needs more than APIs and package distribution.
Publishers and developers need:
clear documentation
migration guidance
compatibility information
support
examples
release communication
education
Without governance, developer-relations systems can become:
outdated docs
contradictory support answers
hidden partner favoritism
undocumented breaking changes
support escalation by revenue
developer surveillance
The governing principle is:
SIAR developer relations must make platform behavior understandable, predictable, versioned, and supportable while keeping support access fair, documentation authoritative, and developer telemetry privacy-minimized.

3. Core Separation
Keep distinct:
documentation
support
governance decision
certification
commercial account
developer telemetry
marketplace ranking
4. Non-Goals
Part 150 does not create:
pay-to-support priority that changes security rules
undocumented partner APIs
private compatibility truth
developer productivity surveillance
support access to user content by default
5. Developer Identity
#![allow(unused)] fn main() { pub struct DeveloperAccountId(pub [u8; 16]); }
6. Publisher Identity
Publisher identity remains distinct from developer account.
7. Hard Rule
Developer account activity does not become extension trust score.
8. Support Identity
#![allow(unused)] fn main() { pub struct DeveloperSupportCaseId(pub [u8; 16]); }
9. Support Case Type
#![allow(unused)] fn main() { pub enum DeveloperSupportCaseType { Documentation, SdkIntegration, Compatibility, Certification, Marketplace, BillingLicensing, IncidentFollowup, Migration, } }
10. Hard Rule
Support case class explicit.
11. Support Priority
Based on:
security severity
service impact
release blocker
contracted support tier
12. Hard Rule
Commercial tier may affect response-time SLA but cannot alter security/privacy/governance outcome.
13. Support State
#![allow(unused)] fn main() { pub enum DeveloperSupportCaseState { Open, Triage, WaitingForDeveloper, Investigating, Resolved, Closed, } }
14. Documentation Authority
Documentation must have source-of-truth ownership.
15. Documentation Source
#![allow(unused)] fn main() { pub enum DeveloperDocumentationSource { ApiSchema, ProtocolRegistry, PolicyRegistry, HandwrittenGuide, GeneratedReference, } }
16. Hard Rule
Generated reference is tied to exact schema/version.
17. Docs-as-Code
Recommended structure:
docs/
├── concepts/
├── guides/
├── api/
├── migration/
├── compatibility/
├── examples/
└── troubleshooting/
18. Hard Rule
Documentation changes reviewed like code.
19. Documentation Version
#![allow(unused)] fn main() { pub struct DocumentationVersion(pub u32); }
20. Hard Rule
Docs identify applicable host/SDK/protocol versions.
21. No Floating Documentation
Hard rule.
22. Documentation Metadata
#![allow(unused)] fn main() { pub struct DocumentationPageMetadata { pub version: DocumentationVersion, pub applies_to: VersionRange<Version>, pub last_verified_at: Timestamp, } }
23. Hard Rule
Stale/unverified docs visibly marked.
24. API Reference
Generated from stable IDL/schema.
25. Hard Rule
Code snippets compile in CI.
26. Example Projects
Reference apps are first-class.
27. Hard Rule
Examples use current security/privacy best practices.
28. No Legacy Unsafe Copy-Paste
Hard rule.
29. Example Certification
Examples tested against supported SDK.
30. Hard Rule
Broken example blocks documentation release where critical.
31. Migration Guide
#![allow(unused)] fn main() { pub struct ExtensionMigrationGuide { pub from: VersionRange<SdkVersion>, pub to: SdkVersion, pub breaking_changes: Vec<MigrationChange>, } }
32. Migration Change
#![allow(unused)] fn main() { pub struct MigrationChange { pub area: MigrationArea, pub required_action: String, } }
33. Migration Area
#![allow(unused)] fn main() { pub enum MigrationArea { Api, Protocol, Permission, DataSchema, Ui, BackgroundJobs, Packaging, Commerce, Licensing, } }
34. Hard Rule
Breaking changes have explicit remediation.
35. Compatibility Communication
Part 129 registry is source of truth.
36. Hard Rule
Marketing/support copy cannot contradict compatibility registry.
37. Compatibility Notice
#![allow(unused)] fn main() { pub struct CompatibilityNotice { pub extension_sdk: VersionRange<SdkVersion>, pub host: VersionRange<Version>, pub status: CompatibilityState, } }
38. Hard Rule
Unknown remains Unknown.
39. Deprecation Communication
Part 128 lifecycle data drives notice.
40. Hard Rule
Deprecation has:
announcement
replacement path
migration guide
support window
sunset date
where applicable.
41. No Surprise Breaking Change
Hard rule.
42. Change Announcement
#![allow(unused)] fn main() { pub enum DeveloperChangeClass { Informational, Additive, Deprecating, Breaking, SecurityCritical, } }
43. Hard Rule
Security-critical change can shorten notice but must still document required action.
44. Release Notes
Versioned and machine-linkable.
45. Hard Rule
Release notes separate:
new features
bug fixes
security changes
breaking changes
46. Security Advisory
Publisher-facing advisory may include:
affected SDK
required migration
deadline
fixed version
47. Hard Rule
No user-specific exposure disclosure in developer bulletin.
48. Migration Readiness Check
Developer tool can evaluate project manifest.
49. Hard Rule
Tool reports compatibility facts, not opaque success score.
50. Developer Portal Integration
Part 131.
51. Hard Rule
Portal surfaces version-pinned documentation.
52. CLI Integration
Part 132.
53. Hard Rule

Offline docs carry version/freshness metadata.
56. Documentation Bundle
#![allow(unused)] fn main() { pub struct OfflineDeveloperDocsBundle { pub version: DocumentationVersion, pub compatibility_snapshot: Digest, pub docs_digest: Digest, } }
57. Support Workflow
developer submits case
→ classify
→ collect minimal diagnostics
→ reproduce
→ answer/fix/docs update
→ close
58. Hard Rule
Support asks for minimum necessary information.
59. Reproduction Bundle
Use synthetic or redacted data.
60. Hard Rule
No production user content by default.

63. Hard Rule
Secrets stripped before upload.
64. Support Redaction
Automatic preflight scanner + schema constraints.
65. Hard Rule
Scanner is supplemental; structured data remains primary defense.
66. Support Access
Support staff role-scoped.
67. Hard Rule
Support role does not imply production/user-data access.
68. Escalation
#![allow(unused)] fn main() { pub enum DeveloperSupportEscalation { SdkEngineering, Security, Privacy, MarketplaceGovernance, BillingLicensing, } }
69. Hard Rule
Escalation routes case, not authority expansion.
70. Contracted Support
Enterprise publishers may receive faster response.
71. Hard Rule
Same platform/security rules apply.
72. No Hidden API Access
Hard rule.
73. Partner Programs
If introduced, benefits may include:

least authority
bounded IPC
local-first storage
privacy-safe telemetry
update-safe state
85. Hard Rule
Tutorials do not normalize shortcuts that production policy forbids.
86. Workshops / Office Hours
Optional.
87. Hard Rule
Attendance is not trust/certification evidence.
88. Certification Training
Explains process, but does not guarantee outcome.
89. Hard Rule
No “pay for training, get certified” coupling.
90. Knowledge Base
Versioned Q&A.
91. KB Article
#![allow(unused)] fn main() { pub struct DeveloperKnowledgeArticle { pub article_id: DeveloperKnowledgeArticleId, pub applies_to: VersionRange<SdkVersion>, pub provenance: DocumentationProvenance, } }
92. Hard Rule
KB answers link to authoritative source.
93. AI-Assisted Support

invent undocumented API
override policy
approve certification
decide governance appeal
96. Hard Rule
AI-generated code treated as untrusted until compiled/tested.
97. Support AI Data
Developer-submitted data may be used in case context under policy.
98. Hard Rule

Structured channels:
docs feedback
SDK feature request
compatibility issue
bug report
policy clarification
100. Feedback Identity
#![allow(unused)] fn main() { pub struct DeveloperFeedbackId(pub [u8; 16]); }
101. Hard Rule
Feedback does not become developer reputation score.
102. Feature Request
Can be public/private.
103. Hard Rule
Votes/popularity do not override security/privacy architecture.
104. Roadmap Communication
Can publish:
planned
in progress
preview
GA
deferred
105. Hard Rule
Roadmap is not contractual guarantee unless explicitly stated.
106. Compatibility Calendar
Useful for upcoming changes.
107. Hard Rule
Calendar uses versioned lifecycle data.
108. Breaking Change Budget
Platform governance may limit frequent breaking changes.
109. Hard Rule
No arbitrary KPI score; use concrete change counts/windows.
110. Migration Window
Defined by lifecycle policy.
111. Hard Rule
High-risk security deprecation can shorten window.
112. Developer Notification Preferences
#![allow(unused)] fn main() { pub struct DeveloperCommunicationPreferences { pub security: bool, pub compatibility: bool, pub deprecation: bool, pub product_news: bool, } }
113. Hard Rule
Security-critical notices may bypass marketing opt-out when contract/platform policy requires, but remain narrowly scoped.
114. Marketing Separation
Product marketing is separate from operational communication.
115. Hard Rule
Support/compatibility channel cannot be used as hidden marketing channel.
116. Communication Channel

support “difficulty” score by person
127. Hard Rule
Developer-relations telemetry is ecosystem friction data, not workforce analytics.
128. Documentation Analytics
Aggregate:
page view count
search no-result rate
outdated-page exits
129. Hard Rule
No cross-site/user behavioral profiling.
130. Privacy-Safe Search Analytics
Hash/cluster queries only where safe or keep local aggregation.
131. Hard Rule
Never retain secrets pasted into docs search.
132. Error Catalog
Stable error codes.
133. Hard Rule
Every public SDK error should map to versioned docs where feasible.
134. Error Documentation
#![allow(unused)] fn main() { pub struct DeveloperErrorDoc { pub code: StableErrorCode, pub meaning: String, pub remediation: Vec<String>, pub versions: VersionRange<SdkVersion>, } }
135. Hard Rule
Error message avoids leaking private system internals.
136. Migration Tooling

Requires migration plan.
153. Hard Rule
No accepted breaking RFC without compatibility/lifecycle analysis.
154. Documentation Governance
Need ownership.
155. Documentation Owner

158. Docs Review
Technical + security/privacy where relevant.
159. Hard Rule
Permission/security docs changes require domain review.
160. Generated Documentation
Prefer source-linked generation.
161. Hard Rule
Generated docs preserve schema/version provenance.
162. Documentation Drift Detection
CI compares schema/API changes to docs coverage.
163. Hard Rule
Breaking API change without docs/migration entry blocks release where policy requires.
164. Compatibility Drift Detection
Registry vs portal docs automated checks.
165. Hard Rule
Portal cannot claim unsupported version.
166. Knowledge Expiry
Docs can have review-by date.
167. Hard Rule
Expired review does not delete docs; marks them needing verification.
168. Archived Docs
Available for old supported versions.
169. Hard Rule
Archived page clearly marked.
170. Search
Search results prioritize matching version.
171. Hard Rule

209. Hard Rule
Breaking stable API requires governed exception/lifecycle process.
210. Supportability Classification
#![allow(unused)] fn main() { pub enum DeveloperSupportability { Supported, BestEffort, Unsupported, } }
211. Hard Rule
Unsupported integration path clearly labeled.
212. No Shadow Support Contract
Hard rule.
213. Migration Assistance

Support cannot mark failed certification as passed.
217. Governance Assistance
Support can explain policy text.
218. Hard Rule

Exceptions cannot alter security/privacy/governance substance.
226. Audit
High-value events:
breaking-change publication
security bulletin
support privileged-access request
docs compatibility correction
227. Hard Rule
Audit does not record routine docs reading by developer.
228. Transparency
Publish:
SDK lifecycle
breaking changes
support scope
certification process
appeal links
229. Hard Rule
No vague hidden process.
230. Developer Relations Metrics
Safe aggregate:
support case volume by category
median response time
docs stale-page count
migration blocker classes
231. Forbidden:
developer ranking
publisher “difficulty” score
individual productivity
private code profiling
232. Hard Rule
Metrics improve ecosystem friction, not judge people.
233. Support API
#![allow(unused)] fn main() { pub trait DeveloperSupportService { fn create_case( &self, publisher: PublisherId, kind: DeveloperSupportCaseType, ) -> Result<DeveloperSupportCaseId, DeveloperRelationsError>; } }

238. Testing
Need developer-relations testkit.
Required scenarios:
versioned docs
breaking change
support case
migration guide
AI support
security bulletin
239. Docs Version Test
Old SDK query returns matching archived docs, not latest silently.
240. Breaking Change Test
Breaking API release blocked without migration doc.
241. Compatibility Test
Portal/docs cannot claim Supported where registry says Unknown.
242. Support Privacy Test
Redacted support bundle contains no secret/private payload.
243. Commercial Fairness Test
Paid support tier changes response SLA only, not policy outcome.
244. AI Test
AI cannot invent unavailable API or certify extension.
245. Incident Test
Security bulletin contains no user identity.
246. Analytics Test
Docs telemetry cannot produce developer-level productivity profile.
247. Fuzzing
Fuzz:
docs metadata
compatibility notices
migration reports
support attachment manifests
248. Property Tests
Properties:
documentation version can never claim compatibility outside authoritative registry
support tier can never bypass mandatory security/privacy review
developer telemetry can never include developer productivity fields
AI support output can never mutate certification/governance state
249. Formal Verification Targets
Strong candidates:
compatibility communication precedence
support escalation authority
docs lifecycle
breaking-change release gate
250. Kani Candidate
version/support-policy invariants.
251. TLA+ Candidate
platform change → docs/migration notice → publisher update → compatibility verification
252. Loom Candidate
Concurrent:
SDK release

portal cache refresh
253. Performance
Docs/support are control-plane services.
254. Hard Rule
No docs/support lookup in runtime hot path.
255. Offline Cache
Docs bundle cached locally.
256. Hard Rule
Cache freshness visible.
257. Search Index
Version-aware.
258. Hard Rule
No private project code indexed without explicit action.
259. Storage Domains
Separate:
documentation
support cases
compatibility notices
migration guides
education content
developer preferences
260. Hard Rule
No user messaging/contact data.
261. Secrets
Support attachments and auth credentials stored separately/securely.
262. Hard Rule
No plaintext project secret in docs/support DB.
263. Partitioning
By:
publisher
project
SDK version
documentation domain
support case
264. Hard Rule
No developer-behavior analytics partition.

276. Security, Privacy & Correctness Invariants
Mandatory:
1. Documentation, support, compatibility communication, certification, marketplace governance, commerce, licensing, developer education, developer telemetry, and runtime authority are distinct domains and cannot be used as hidden substitutes for one another.
2. Developer documentation is versioned, source-linked, compatibility-aware, and reviewed; generated API references bind exact schemas, examples compile/test in CI, and stale/archived docs are clearly marked rather than silently presented as current.
3. Compatibility status comes from the authoritative compatibility registry; portals, support agents, AI assistants, marketing content, and developer relations staff can never override Unknown/Unsupported state by assertion.
4. Breaking/deprecating changes include explicit release notes, migration guidance, replacement path, support window, and lifecycle metadata where applicable; emergency security changes may shorten notice but cannot omit required remediation instructions.
5. Support workflows collect only minimal technical data, use redacted/synthetic reproducers by default, never require production user content, and do not grant support personnel ambient access to user data, extension secrets, or runtime authority.
6. Commercial support tiers may alter response-time/service levels but can never change security/privacy requirements, certification outcomes, marketplace enforcement, compatibility truth, incident handling, or access to hidden privileged APIs.
7. Partner programs, office hours, training, preview access, and education improve developer capability but cannot substitute for qualification/certification, create pay-to-trust pathways, or grant unpublished production behavior.
8. AI-assisted developer support remains source/version grounded and advisory; it cannot invent undocumented APIs, mutate governance/certification state, waive policy, approve releases, or treat AI-generated code as trusted without compilation/testing.
9. Developer-relations telemetry measures ecosystem friction—stale docs, support categories, search failures, migration blockers—without developer productivity scoring, private code profiling, workforce analytics, user-level tracking, or cross-site behavioral advertising.
10. Support/compatibility/security communications are separated from marketing, critical notices are authenticatable, publisher preferences are respected except narrowly scoped mandatory operational/security communication, and notice delivery does not require behavioral tracking.
11. Knowledge-base reuse, support-case-derived documentation, analytics, and incident communications remove publisher/user-sensitive identifiers and never expose private tenant/user information beyond authorized support scope.
12. Developer relations integrates with SDKs, docs portals, CLI tooling, compatibility registry, lifecycle governance, updates, testing/certification, marketplace governance, incidents, commerce, licensing, and policy distribution without creating a side channel around SIAR's security, privacy, anonymity, local-first, or tenant-isolation guarantees.
277. Initial Production Scope
Implement first:
versioned docs-as-code
generated API references
version-aware docs search
CI-tested code examples
migration guides
deprecation/breaking-change notices
compatibility notices sourced from registry
offline signed docs bundle
developer support case lifecycle
minimal/redacted support attachments
support escalation
security bulletin channel
developer communication preferences
learning paths/reference architectures
SDK error catalog
CLI migration assessment
AI docs assistant with source/version grounding
docs drift detection
aggregate developer-relations metrics
devrel testkit
Then add:
public RFC workflow
advanced automated migration assistant
localized critical docs
compatibility calendar
structured publisher office-hours tooling
privacy-preserving docs-search analytics
formal docs/compatibility consistency proofs
278. Definition of Done
Part 150 is complete when:
- docs are versioned and authoritative;
- compatibility communication cannot contradict registry truth;
- breaking changes include migration guidance;
- examples compile/test;
- support collects minimal/redacted data;
- paid support cannot buy policy exceptions;
- education/partner status cannot bypass certification;
- AI support is source/version grounded and non-authoritative;
- developer telemetry measures ecosystem friction, not productivity;
- critical communication is separated from marketing;
- offline docs and archived-version support exist;
- docs/support/compatibility/privacy/AI/fuzz/formal tests are specified.

PUBLISHER ADOPTION
Developer-success safety model:
versioned authoritative docs
+
compatibility truth
+
migration guidance
+
minimal-data support
+
education
+
signed communication
+
source-grounded AI
+
privacy-safe ecosystem metrics
not:
undocumented changes, VIP APIs, revenue-based policy exceptions, support agents with production data access, and developer surveillance disguised as success analytics
280. Final Principle
Developer relations is trustworthy when a publisher can answer what changed, which version is supported, how to migrate, where the authoritative documentation lives, how to get help, and which support/education mechanisms cannot alter platform trust rules.
The correct model is:
document exact versions
+
communicate compatibility truth
+
announce changes early
+
provide migration guidance
+
support with minimum data
+
teach secure patterns
+
ground AI assistance in authoritative sources
+
measure ecosystem friction instead of people
+
never turn developer success into favoritism or surveillance
This architecture gives SIAR a privacy-preserving developer-success foundation for documentation governance, compatibility communication, migration assistance, publisher support, education, AI-assisted help, lifecycle notices, and ecosystem learning while preserving the anonymity, local-first, least-authority, marketplace-governance, commerce, licensing, certification, incident-response, and anti-surveillance guarantees established across Parts 34–149.
