Owner

Replaces the placeholder-only repository state with the minimum deterministic SentinelAI backend foundation.

Changes:

  • real FastAPI health endpoint and health test
  • deterministic transaction risk engine
  • strict transaction decision API contract
  • high-confidence malicious destination blocking boundary
  • high-confidence malicious unlimited-spender blocking boundary
  • PostgreSQL reputation and decision telemetry schema
  • API and risk-engine regression tests
  • pytest/development dependencies
  • GitHub Actions CI
  • removes the accidental commit file that only described a proposed repository tree

Scope is intentionally narrow: no ML, no additional intelligence sources, no speculative infrastructure. Next boundary after this PR is wallet interception.

Review Change Stack

📝 Walkthrough

Summary

  • Added FastAPI /health and /v1/check-tx endpoints.
  • Added strict Pydantic request validation.
  • Added deterministic transaction risk evaluation.
  • Blocks high-confidence malicious destinations and spenders.
  • Warns for unknown or low-confidence risk and unlimited approvals.
  • Added PostgreSQL reputation and decision telemetry schema.
  • Added API, health, and risk-engine regression tests.
  • Added development dependencies and GitHub Actions CI.
  • Removed the accidental repository scaffold file.

The implementation excludes ML, additional intelligence sources, and speculative infrastructure. The next boundary is wallet interception.

Walkthrough

The change adds deterministic transaction-risk evaluation, a FastAPI health and transaction-check API, telemetry tables, endpoint and engine tests, pytest configuration, development dependencies, and GitHub Actions CI.

Changes

Risk evaluation and API foundation

Layer / File(s) Summary
Transaction risk policy
services/intelligence/sentinel_risk/engine.py, tests/test_risk_engine.py
The engine defines reputation and decision types, evaluates transaction risk, and tests malicious destinations, spenders, unknown destinations, and unlimited approvals.
Risk-check API contract and wiring
services/api/app/models.py, services/api/app/main.py, services/api/requirements.txt, tests/test_api.py, tests/test_health.py
The FastAPI app validates request models, exposes /health and /v1/check-tx, invokes the risk engine, and returns the policy version.
Decision telemetry schema
services/telemetry/schema.sql
The schema adds reputation and decision event tables with constraints and indexes.
Test discovery and CI execution
pyproject.toml, requirements-dev.txt, .github/workflows/ci.yml, commit
Pytest discovery, local imports, development dependencies, and Python 3.12 CI execution are configured. The directory-tree documentation file is removed.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to 2f798

This PR introduces a security-decision API, but the current implementation can allow medium-confidence malicious destinations, relies on caller-provided reputation data without an established integrity boundary, and may miss malicious unlimited approvals when the approval flag is omitted; its CI workflow also exposes a read-scoped checkout token to repository-controlled commands. Merge should wait until these risks are fixed or explicitly accepted by the appropriate owners.

Poem

A rabbit checks each address bright,

Malice stops beneath moonlight.
Unknown signs raise warnings clear,
Tests hop through the code with cheer.
CI runs softly through the night.

ECC Tools uses this to decide whether recommendations should stay at commit-history/setup guidance or expand into CI, security, harness, reference-set, AI-routing, and team backlog work.

Area Status Evidence / Next Step
Commit history Ready 18 commits sampled
CI/CD signals Ready .github/workflows/ci.yml
Security evidence Missing Add AgentShield, audit, SARIF, SBOM, or security review evidence so recommendations can cover security posture.
Harness configuration Missing Add Claude, Codex, OpenCode, Zed, dmux, MCP, plugin, or cross-harness config evidence for harness-agnostic recommendations.
Reference/eval evidence Missing Add fixtures, golden traces, reference sets, or evaluator benchmarks so deeper recommendations have regression evidence.
AI routing and cost controls Missing Add model-routing, budget, usage, or cost-control files before relying on AI-heavy automation recommendations.
Team handoff and project tracking Missing Add roadmap, runbook, project, Linear, or follow-up tracking docs so generated work can land in a team queue.
Reference Set Readiness (0/7, 0%)
Area Status Evidence / Next Step
Deep analyzer corpus Missing Add analyzer fixture, golden, benchmark, or reference-set files that can catch analyzer regressions.
RAG/evaluator comparison Missing Add retrieval or evaluator reference-set comparison fixtures with expected ranking behavior.
PR salvage/review corpus Missing Add stale-PR, review-thread, reopen-flow, or salvage reference cases for queue cleanup automation.
Discussion triage corpus Missing Add public discussion triage fixtures, golden cases, or reference sets for informational, answered, and no-response classifications.
Harness compatibility Missing Add cross-harness, adapter-compliance, or harness-audit evidence for Claude, Codex, OpenCode, Zed, dmux, and agent surfaces.
Security evidence Missing Attach security evidence such as SBOMs, SARIF, audit reports, or AgentShield evidence packs.
CI failure-mode evidence Missing Add captured CI failure logs, dry-run fixtures, or troubleshooting docs for common workflow failure modes.
Likely Future Issues (5)
Severity Signal Why it may show up
HIGH API contract changes may ship without integration coverage 5 API surface paths changed; 0 integration or e2e tests changed
MEDIUM API implementation changes may ship without contract artifact updates 5 API implementation paths changed; 0 API contract/spec files changed
HIGH Schema or model changes may ship without migration follow-up 1 schema/model paths changed; 0 migration files changed
MEDIUM CI workflow changes may ship without failure-mode evidence 1 CI/test-runner paths changed; 0 CI failure-mode evidence artifacts changed
MEDIUM Dependency or CI drift could surface after merge CI/workflow files changed; no lockfile changes detected
  • API contract changes may ship without integration coverage: The PR changes API or route-facing files but does not touch any obvious integration or end-to-end tests.
  • API implementation changes may ship without contract artifact updates: The PR changes API implementation files but does not touch any obvious OpenAPI, GraphQL, or contract/spec artifact.
  • Schema or model changes may ship without migration follow-up: The PR changes schema or model-facing files but does not include any obvious migration artifact.
  • CI workflow changes may ship without failure-mode evidence: The PR changes CI workflows or test-runner entrypoints without touching CI failure fixtures, captured logs, troubleshooting notes, or regression evidence.
  • Dependency or CI drift could surface after merge: Package or workflow changes landed without an accompanying lockfile update, which often turns into CI or release noise later.
