#24 perform aegis contracts audit readiness review fix

[onakijames-droid]

CLOSE #24 Pull Request Description: Audit Readiness Review

Description

Performed a full audit readiness review of the Aegis RWA Contracts (onakijames-droid/aegis-contracts) prior to submitting the codebase for formal third-party security audits.

Specifically, this change:

1. Created a comprehensive audit readiness document at docs/audit-readiness.md evaluating KYC enforcement, admin controls, minting limits, transfer restrictions, storage layout, events, errors, pause behavior, SDK compatibility, and dashboard readiness.
2. Formally documented 4 high-risk security blockers ([BLK-01] to [BLK-04]), 5 unresolved design decisions & architectural limitations ([DEC-01] to [DEC-05]), 11 missing security/boundary test cases (TST-01 to TST-11), and 4 SDK & off-chain dashboard risks ([SDK-01] to [SDK-04]).
3. Explicitly stated technical limitations, legal assumptions, and incomplete work (such as the event-only yield distribution mock, lack of KYC revocation/freeze, and absence of an emergency pause).
4. Updated README.md to add a dedicated Audit Readiness section linking directly to docs/audit-readiness.md.

Completion Table

Acceptance Criterion	Status	Implementation Evidence	Test Evidence	Documentation Impact
AC 1: Audit readiness review is added	Complete	Created docs/audit-readiness.md covering all 10 requested areas (KYC enforcement, admin controls, minting limits, transfer restrictions, storage layout, events, errors, pause behavior, SDK compatibility, and dashboard readiness).	Verifiable via document inspection (docs/audit-readiness.md). No-test justification: documentation deliverable.	Created docs/audit-readiness.md (v1.0 comprehensive report).
AC 2: High-risk areas are identified	Complete	Section 2 of docs/audit-readiness.md details 4 critical/high-risk blockers: [BLK-01] Missing KYC Revocation / Frozen Asset Handling, [BLK-02] Absence of Emergency Pause, [BLK-03] Missing Token Burn & Clawback, and [BLK-04] Single-Step Admin Ownership & Lack of RBAC.	Identified vulnerabilities and gaps against existing contract logic in src/lib.rs, src/compliance.rs, and src/asset.rs.	Documented in Section 2 (docs/audit-readiness.md).
AC 3: Missing test coverage is listed	Complete	Section 4 of docs/audit-readiness.md lists 11 missing security unit test cases (TST-01 to TST-11), including negative tests for unauthorized minting/whitelisting, unwhitelisted transfers, overflow/underflow checks, self-transfers, and strict auth boundaries without mock_all_auths().	Audited src/test.rs (9 existing tests) and identified specific coverage gaps for failure paths and privileged auth assertions.	Documented in Section 4 (docs/audit-readiness.md).
AC 4: Unresolved design decisions are listed	Complete	Section 3 of docs/audit-readiness.md lists 5 core design decisions and explicit limitations ([DEC-01] to [DEC-05]): Yield Distribution Scalability (distribute_yield mock), Transfer Fee Deduction Mechanics, Batch Whitelisting Gas Efficiency, Storage TTL & Rent-Exemption Archival Strategy, and Legal/Regulatory Assumptions.	Identified all // TODO: markers and architectural trade-offs in src/asset.rs, src/compliance.rs, and docs/architecture.md.	Documented in Section 3 (docs/audit-readiness.md).
AC 5: SDK and dashboard risks are included	Complete	Section 5 of docs/audit-readiness.md lists 4 cross-repo/SDK risks ([SDK-01] to [SDK-04]): Absence of public Soroban RPC WebSocket subscriptions (HTTP 429 polling risks), Ledger Reorg Event Deduplication in event-store.js, XDR Schema Drift between #[contractevent] and scval.js, and SEP-41 explorer compatibility.	Audited .github/monitoring/ Node service, WebSocket client, event store, and ScVal XDR decoder.	Documented in Section 5 (docs/audit-readiness.md).
AC 6: README links to the review	Complete	Added ## Audit Readiness section to README.md with a direct markdown link to docs/audit-readiness.md.	Verified markdown formatting and navigation link in README.md.	Updated README.md (inserted section prior to ## Contributing).

Detailed Traceability Mapping

Acceptance Criteria	Implementation	Storage & State Changes	Events Emitted	Test Coverage	Security/Safety Controls
AC 1: Audit readiness review is added	docs/audit-readiness.md created with full review methodology across src/ and .github/monitoring/.	N/A (Documentation audit review)	N/A	N/A (Documentation audit review)	Evaluates and documents all required security controls across 10 functional domains.
AC 2: High-risk areas are identified	docs/audit-readiness.md Section 2 ([BLK-01] to [BLK-04]).	Recommends new storage flags: DataKey::Paused and blacklist/freeze states in compliance.rs.	Recommends adding events for KYC removal, freeze, pause/unpause, burn, and clawback.	Recommends negative test cases for every blocker identified.	Identifies absence of circuit breakers, KYC revocation, burn/clawback, and multi-role RBAC.
AC 3: Missing test coverage is listed	docs/audit-readiness.md Section 4 (TST-01 to TST-11).	N/A	N/A	Maps 11 missing test cases to src/test.rs to validate failure paths and strict auth boundaries (mock_auths).	Establishes test requirements for authorization, overflow/underflow, self-transfer invariant, and circuit breaker enforcement.
AC 4: Unresolved design decisions are listed	docs/audit-readiness.md Section 3 ([DEC-01] to [DEC-05]).	Identifies storage scaling risks in distribute_yield and TTL extension requirements for persistent storage.	Details how yield snapshot vs. pull-based dividend accounting affects event emission.	Recommends tests for fee rounding and TTL extension behavior.	Explicitly defines legal and technical assumptions (off-chain identity verification and off-chain physical asset custody).
AC 5: SDK and dashboard risks are included	docs/audit-readiness.md Section 5 ([SDK-01] to [SDK-04]).	Analyzes off-chain database deduplication (event-store.js) under ledger reorgs.	Evaluates aegis namespaced event topics (src/events.rs) against JavaScript ScVal decoding (scval.js).	Highlights need for automated CI contract-to-SDK compatibility tests on schema changes.	Recommends RPC rate-limit backoff, idempotency keys, and strict XDR schema validation in the monitoring tier.
AC 6: README links to the review	README.md (## Audit Readiness section added).	N/A	N/A	N/A	Ensures visibility of audit readiness status and known limitations for auditors and contributors.
