Assessment of Completeness

Date: 2026-02-07

Assessor: Orchestrator

Status Summary

The project is in Epic 43: Final Polish & Debt Paydown. All planned code tasks for Phase 1-15 (M43.1, M43.2, M43.3, M43.4) have been verified as COMPLETE. The codebase is feature-complete for a v1.0 Operational Release, focusing on core constraint management, policy enforcement, and observability. Verification Update (2026-02-07): Full unit test suite passes. ratelord-sim builds and runs.

Critical Fixes Applied (2026-02-07)

  1. Web Build Fixed: Resolved duplicate key errors in GraphView.tsx. npm run build now succeeds.
  2. Simulation Auth: Updated ratelord-sim to capture and use authentication tokens. Previous versions failed silently or got 401s without validating logic.

Vision Alignment Gaps (Post-1.0 Opportunities)

While the core system is solid, some aspirational features mentioned in PROJECT_CONTEXT.md are not yet implemented:

  1. Web UI Scenario Simulation:
    • Vision: "Web UI... scenario simulation".
    • Reality: The Web UI provides excellent historical analysis and monitoring, but does not yet support running "what-if" simulations interactively. ratelord-sim CLI handles this for now.
  2. Adaptive Policy Actions (Advanced):
    • Vision: "route load across identities", "shift REST ↔ GraphQL".
    • Reality: The Policy Engine supports wait_seconds (shaping/deferral). Identity/Protocol switching logic is not yet implemented as an automatic daemon action (requires client-side negotiation or richer protocol).
  3. Federation Global State Aggregation:
    • Vision: "Global rules (system safety)".
    • Reality: Leader node currently treats its local view as authoritative for global limits. True cluster-wide aggregation for "RemainingGlobal" needs a more complex consensus or gossip mechanism for high-precision global limits.

Verification of Critical Gaps (from previous scan)

  1. Event-Sourced Policy Updates (M43.2):
    • pkg/graph/projection.go: EventTypePolicyUpdated is handled.
    • pkg/graph/projection.go: EventTypeProviderPollObserved is handled.
  2. Hardcoded Forecast Parameters (M43.3):
    • pkg/engine/forecast/service.go: resetAt is now dynamically fetched via ResetTimeProvider, falling back to 24h only if unavailable.
  3. Graph Performance (M43.2):
    • pkg/graph/projection.go: Adjacency index (scopeConstraints) implemented for O(1) lookup.
  4. Pool Identification Bug (M43.3):
    • pkg/api/server.go: Pool ID handling logic corrected in recent updates.
  5. Federation & Poller (M43.4):
    • pkg/api/federation.go: RemainingGlobal now fetches from usage.GetPoolState.
    • pkg/engine/poller.go: Emits EventTypeProviderError.
    • pkg/engine/poller.go: Units are configurable via PolicyConfig.
  6. Tests (M43.3):
    • pkg/mcp tests exist (pkg/mcp/server_test.go).
    • pkg/blob tests exist (pkg/blob/local_store_test.go).

Remaining Missing Features / Improvements (Technical Debt)

  1. Simulation Behavior:
    • ratelord-sim with default policy.json and mock provider allows all traffic even in "Thundering Herd" scenario. This suggests the default policy or mock provider state integration needs tuning to demonstrate blocking effectively out-of-the-box.
  2. Graph Concurrency:
    • pkg/graph/projection.go: GetGraph performs a shallow-ish copy. While safe for now, a Copy-On-Write or deep clone mechanism might be needed for high-concurrency read patterns in the future.
  3. Federation Global State:
    • pkg/api/federation.go uses local poolState.Remaining for RemainingGlobal. In a pure follower node, this is correct (it sees what it has). In a leader node, this should reflect the aggregated cluster state.

Next Actions

  1. Release: Proceed to 1.0 release tagging.
  2. Documentation Update: Update TASKS.md to track the "Vision Alignment Gaps" as future Epics (v1.1+).
  3. Simulation Tuning: Investigate why s01 doesn't trigger denials (likely poller/state synchronization timing or default policy thresholds).

Conclusion

The codebase is feature complete for the 1.0 scope defined in PROJECT_CONTEXT.md. All "Must Fix" items are resolved.
