Before starting the paper trading phase, SPA underwent a thorough internal architecture review covering every layer of the system: data ingestion, strategy execution, risk gating, state persistence, and operational infrastructure.
Audit Coverage
All read-only adapters verified. Zero cross-domain imports from execution/. DeFiLlama feed with TTL-300s cache validated.
Deterministic gate confirmed. No LLM calls, no override paths. Snapshot archived in spa_core/risk/versions/.
29 criteria verified. gate locks functional. gap_monitor integration confirmed.
com.spa.daily_cycle and com.spa.httpserver active. com.spa.autopush NOT installed — fix pending (mp009_fix_launchd.command).
All state files use tmp + os.replace pattern. No direct open(..., "w") on JSON state files.
PAT stored in macOS Keychain only. Zero tokens in files post-incident remediation.
execution/ not importable from read-only code. LLM_FORBIDDEN enforced for risk/execution/monitoring.
Key Findings
The architecture is sound for paper trading. The primary blocker for GoLiveChecker is
not a design issue but an operational one: com.spa.autopush daemon
is not installed, which blocks the autopush_installed.
The domain isolation between spa_core/adapters/ (read-only)
and spa_core/execution/ is correctly enforced.
No cross-contamination was found in 800+ test files.
RiskPolicy v1.0 has zero discretionary override paths. The kill switch at 5% drawdown and the per-protocol caps (40% T1, 20% T2) are hard-coded and untouchable during the paper trading period.
