Core System Architecture Part 147 — Anonymous Network Extension Governance, Publisher Policy, Ecosystem Rules, Dispute Resolution, Appeals, Enforcement Consistency & Privacy-Preserving Marketplace Governance Architecture
SIAR — Secure, Local-First, Multi-Transport Communication Platform
Series: Core System Architecture
Part: 147
Status: Architecture specification
Primary language: Rust
Builds on: Core System Architecture Parts 53, 55–56, 69, 94–99, 104, 108, 119–126, 133–146
Primary purpose: define SIAR's extension ecosystem-governance architecture for publisher policy, marketplace rules, enforcement classes, appeals, dispute resolution, policy consistency, conflict-of-interest controls, sanctions, reinstatement, policy evolution, enterprise/private-marketplace overlays, and privacy-preserving governance.
1. Purpose
An extension ecosystem eventually needs more than technical controls.
It needs rules for:
publisher conduct
marketplace eligibility
acceptable extension behavior
security/privacy expectations
distribution restrictions
enforcement
appeals
reinstatement
Without explicit governance, the ecosystem risks:
arbitrary enforcement
publisher favoritism
opaque delisting
inconsistent sanctions
conflicted decision-makers
policy drift
surveillance-driven moderation
The governing principle is:
SIAR marketplace governance must be rule-based, scoped, evidence-backed, reviewable, appealable, and privacy-preserving, with consistent enforcement and no hidden behavioral ranking of publishers or users.

3. Core Separation
Keep distinct:
policy
rule
violation
incident
enforcement action
appeal
dispute
exception
reinstatement
4. Non-Goals
Part 147 does not create:
arbitrary publisher scoring
political/content ideology ranking
user-behavior surveillance
secret enforcement rules
one-person marketplace dictatorship

Non-critical policy changes may allow migration period.
81. Hard Rule
Transition period explicit.
82. Hard Security Rule
May take immediate effect.
83. Hard Rule
Immediate policy still needs signed version/communication.

When policy materially changes.
85. Hard Rule
Notification does not require tracking publisher behavior.
86. Policy Exception

96. Hard Rule
Precedent guides consistency, not automatic sentencing.
97. Consistency Check
Before severe action, compare analogous cases.
98. Hard Rule
Different outcome requires documented factual/policy distinction.
99. No Automated Sanction Scoring
Hard rule.
100. AI Assistance
May summarize:
case history
policy text
evidence links
101. Hard Rule
AI cannot issue final sanction, approve appeal, or infer intent without human-governed evidence.

106. Hard Rule
Marketplace freezes transfer-sensitive actions while unresolved if necessary.
107. No Destructive Transfer During Dispute
Hard rule.
108. Publisher Key / Identity Dispute
Handled separately from package functional review.
109. Hard Rule
Identity dispute does not automatically delete package data/install history.

126. Hard Rule
Decision rationale references rules/evidence.
127. No Secret Rationale
Hard rule, except security-sensitive evidence details may be redacted.
128. Publisher Due Process
For non-emergency actions, publisher should receive:
rule cited
evidence category
proposed action
response window
129. Hard Rule
Emergency containment can precede response opportunity when necessary.
130. Post-Emergency Review
Required.
131. Hard Rule
Emergency action does not bypass later governance review.
132. Response Window
Time-bounded.
133. Hard Rule
Critical security risk does not require waiting before containment.
134. Remediation Plan
Publisher can propose:
fixed package
permission reduction
dependency replacement
data cleanup
support change
135. Hard Rule
Remediation verified before sanction reduction.
136. Publisher Reinstatement

New package/version may be accepted.
140. Hard Rule
Historical revoked artifact remains revoked.
141. Publisher Transfer
Ownership transfer is high-risk governance event.
142. Hard Rule
Transfer cannot silently carry all trust state.
143. Transfer Review
Check:
new publisher identity
signing keys
support contact
policy acceptance
permission sensitivity
144. Hard Rule
Sensitive extensions may require user/admin notice after publisher change.

157. Private Marketplace Governance
Enterprise can define additional rules.
158. Hard Rule
Enterprise rules cannot weaken global security/privacy floor.
159. Enterprise Allowlist
May restrict available extensions.
160. Hard Rule
Allowlist does not bypass package verification/certification.
161. Private Publisher
Tenant-internal publisher may distribute privately.
162. Hard Rule
Private distribution still follows technical security guarantees.
163. Enterprise Appeals
Tenant may have separate internal process.
164. Hard Rule

appeal latency
policy exception count
reinstatement duration
181. Hard Rule
Process-quality metrics, not publisher/developer performance scoring.
182. Enforcement Latency SLO
Severe security actions may have response target.
183. Hard Rule
Faster is not always better for non-emergency due process.
184. Appeal SLO
Timely review.
185. Hard Rule

192. Governance Quorum
#![allow(unused)] fn main() { pub struct GovernanceQuorumPolicy { pub required_roles: BTreeSet<GovernanceAuthorityRole>, pub minimum_approvals: u8, } }
193. Hard Rule
Quorum cannot be lowered during dispute for convenience.
194. Emergency Quorum
May be narrower for temporary containment.
195. Hard Rule
Permanent sanction still requires ordinary review path afterward.
196. Policy Signing
Governance policies signed.
197. Hard Rule
Clients reject unsigned governance policy.
198. Policy Anti-Rollback
Monotonic epoch/version.
199. Hard Rule
Old permissive policy cannot replace newer restrictive rule set silently.
200. Policy Distribution
Part 61/99 patterns.
201. Hard Rule
Offline clients retain last valid restrictive policy.
202. Policy Staleness
For new installs, stale policy may block high-risk operation.
203. Hard Rule
No permissive fail-open.
204. Governance API
#![allow(unused)] fn main() { pub trait ExtensionGovernanceService { fn effective_policy( &self, scope: ExtensionGovernanceScope, ) -> Result<ExtensionGovernancePolicySnapshot, ExtensionGovernanceError>; } }
205. Enforcement Service
#![allow(unused)] fn main() { pub trait ExtensionEnforcementService { fn propose( &self, violation: ExtensionGovernanceViolation, ) -> Result<ExtensionEnforcementActionId, ExtensionGovernanceError>; fn activate( &self, action: ExtensionEnforcementActionId, ) -> Result<(), ExtensionGovernanceError>; } }
206. Appeal Service
#![allow(unused)] fn main() { pub trait ExtensionAppealService { fn submit( &self, appeal: ExtensionAppeal, ) -> Result<ExtensionAppealId, ExtensionGovernanceError>; fn decide( &self, appeal: ExtensionAppealId, decision: ExtensionAppealDecision, ) -> Result<(), ExtensionGovernanceError>; } }

#![allow(unused)] fn main() { pub trait GovernanceConsistencyService { fn analogous_cases( &self, violation: ExtensionGovernanceViolationId, ) -> Result<Vec<GovernancePrecedent>, ExtensionGovernanceError>; } }
209. Error Taxonomy
#![allow(unused)] fn main() { pub enum ExtensionGovernanceError { PolicyUnknown, RuleUnknown, SubjectUnknown, EvidenceInsufficient, ConflictOfInterest, UnauthorizedDecision, QuorumNotMet, ExceptionNotAllowed, AppealNotAdmissible, ReinstatementNotReady, PolicyStale, RevokedSubject, Internal, } }
210. Policy Storage
Separate:
policy documents
rule registry
precedent records
decision records
appeals
exceptions
reinstatement records
211. Hard Rule
No user behavior data in governance store.
212. Evidence References
Governance store references incident/assurance evidence; does not duplicate private blobs unnecessarily.
213. Hard Rule
Evidence access remains source-policy controlled.
214. Retention
Governance decisions retained long-term for precedent/accountability.
215. Hard Rule
Sensitive raw evidence may have shorter retention than decision metadata.
216. Public vs Internal Record
Separate.
217. Hard Rule
Public transparency does not leak restricted evidence.
218. Testing
Need extension-governance testkit.
Required scenarios:
warning
package suspension
publisher suspension
appeal
reinstatement
conflict-of-interest recusal
219. Evidence Test
Severe sanction rejected if evidence standard unmet.
220. Scope Test
Package-level evidence cannot automatically sanction unrelated publisher packages.
221. Exception Test
Non-waivable rule rejects exception.
222. Appeal Independence Test
Original severe-action approver cannot be sole appeals reviewer.
223. Quorum Test
High-impact decision fails if quorum not met.
224. Consistency Test
Analogous case divergence requires documented rationale.
225. Retroactivity Test
New non-critical rule does not punish already-ended permitted behavior.
226. Transfer Test
Publisher ownership transfer triggers trust re-evaluation.
227. Enterprise Test
Tenant policy cannot override global package revocation.
228. Privacy Test
Governance record has no user behavior fields.
229. Fuzzing
Fuzz:
policy documents
appeal records
exception records
enforcement scopes
decision records
230. Property Tests
Properties:
lower policy can never weaken hard platform invariant
publisher sanction can never implicitly revoke unrelated package without scoped action
appeal can never mutate original decision record
revoked package can never become allowed through lower marketplace policy
231. Formal Verification Targets
Strong candidates:
policy precedence
enforcement lifecycle
appeal/reinstatement transitions
quorum/SoD rules
232. Kani Candidate
scope/precedence/exception invariants.
233. TLA+ Candidate
rule → violation → enforcement → appeal → uphold/modify/vacate → reinstate
234. Loom Candidate
Concurrent:
enforcement activation
appeal stay
emergency disable
policy refresh
235. Performance
Governance is control-plane work.
236. Hard Rule
No governance evaluation on message send/runtime hot path except cached enforcement state.
237. Enforcement Cache
Signed local snapshot.
238. Hard Rule
Revocation/suspension updates invalidate cache promptly.
239. Policy Compilation
Human-readable governance policy:
Markdown explanation
RON typed metadata
Postcard compiled policy
240. Hard Rule
Compiled policy digest binds human source/version.
241. Policy Review Workflow
draft
review
security/privacy check
approve
sign
publish
242. Hard Rule
No direct production mutation.
243. Governance Workspace
Recommended repository structure:
governance/
├── policies/
├── rules/
├── precedents/
├── appeals/
├── transparency/
└── schemas/
244. Hard Rule
Sensitive evidence remains outside public repository.

256. Security, Privacy & Correctness Invariants
Mandatory:
1. Governance policy, rule, violation, incident, enforcement action, appeal, dispute, exception, reinstatement, and marketplace trust state are distinct typed records with explicit scope and immutable history.
2. Enforcement is evidence-backed, rule-cited, and no broader than the demonstrated risk where safe; a package-level violation cannot silently sanction unrelated publisher packages, tenants, users, or extensions without separate scoped authority.
3. Publisher popularity, revenue, advertising spend, app-store ranking, user engagement, or commercial relationship can never grant policy advantage, bypass technical/security rules, determine appeal outcome, or substitute for evidence.
4. Security/privacy hard invariants are non-waivable and dominate marketplace/enterprise/publisher policy; tenant/private marketplaces may restrict further but can never weaken platform revocation, sandbox, cryptographic, privacy, or data-isolation guarantees.
5. Emergency containment may act before ordinary process when necessary, but remains signed, scoped, auditable, and subject to later governance review; temporary emergency authority cannot silently become permanent governance power.
6. Severe enforcement uses separation of duties, conflict-of-interest recusal, and quorum where applicable; an investigator, original decision-maker, conflicted competitor, or revenue owner cannot unilaterally control major sanction and final appeal.
7. Appeals preserve original decision history, cite explicit grounds/evidence, receive independent review for major sanctions, and may narrow/vacate/remand decisions without deleting the historical record or auto-restoring revoked artifacts.
8. Publisher/package reinstatement requires verified remediation, fresh security/privacy/certification evidence, current valid signing identity, and resolved incidents; historical revoked package artifacts remain revoked even after publisher reinstatement.
9. Policy changes are signed, versioned, anti-rollback protected, and normally prospective; ordinary enforcement cannot rely on hidden unpublished rules or retroactively punish completed behavior that was permitted when performed.
10. Marketplace discovery, trust signals, policy enforcement, appeals, user reviews, and transparency reporting are separated from invasive behavioral profiling; no governance process may require user activity timelines, private content, sensitive inferred traits, or publisher/user scoring.
11. Governance metrics and transparency records measure process outcomes—decision latency, appeals, policy changes, enforcement classes—without becoming publisher scoreboards, developer productivity analytics, workforce surveillance, or user-level tracking.
12. Extension governance integrates with marketplace distribution, runtime enforcement, permissions, data governance, state sync, dependencies, updates, certification, observability, incident response, publisher identity, enterprise policy, audit, and evidence archives without creating a side channel around SIAR's security, privacy, anonymity, local-first, or tenant-isolation guarantees.
257. Initial Production Scope
Implement first:
typed governance policy/rule registry
publisher/package governance states

258. Definition of Done
Part 147 is complete when:
- governance policy/rules are versioned and signed;
- publisher/package state is distinct;
- violations are evidence-backed and scoped;
- enforcement is graduated;
- severe sanctions require SoD/quorum where appropriate;
- appeals preserve history and receive independent review;
- conflicts of interest require recusal;
- policy exceptions are bounded/non-waivable where required;
- reinstatement requires verified remediation;
- enterprise/private policy cannot weaken platform floor;
- governance records contain no user-behavior surveillance data;
- policy/scope/appeal/quorum/privacy/fuzz/formal tests are specified.

REINSTATEMENT
Marketplace-governance safety model:
published rules
+
scoped evidence
+
graduated enforcement
+
separation of duties
+
appeals
+
precedent consistency
+
anti-rollback policy
+
privacy-safe transparency
not:
opaque rules, ad-hoc sanctions, pay-to-play exceptions, popularity-based enforcement, and user surveillance used as marketplace governance
260. Final Principle
Extension governance is trustworthy when publishers and users can understand which rule applies, what evidence supports an action, who had authority to decide it, how the decision can be appealed, and what must happen for reinstatement.
The correct model is:
publish clear rules
+
apply them to concrete evidence
+
scope enforcement narrowly
+
separate investigators from appeal authority
+
handle conflicts of interest
+
preserve decision history
+
allow structured appeals
+
verify remediation before reinstatement
+
never turn marketplace governance into commercial favoritism or surveillance
This architecture gives SIAR a privacy-preserving marketplace-governance foundation for publisher policy, ecosystem rules, enforcement, disputes, appeals, consistency, policy exceptions, reinstatement, enterprise overlays, and transparency while preserving the anonymity, local-first, least-authority, marketplace, runtime, permission, data-governance, update, certification, observability, incident-response, and anti-surveillance guarantees established across Parts 34–146.
