# Final Production-Readiness Report

- Date: 2026-02-21
- Environment: local runtime + Docker MongoDB/Redis + live OpenRouter model calls
- Model: `openrouter/openai/gpt-4o-mini`
- Benchmark artifacts:
  - `/Users/supreethravi/supreeth/mongoclaw/.tmp/final_benchmark/results.json`
  - `/Users/supreethravi/supreeth/mongoclaw/.tmp/final_benchmark/results_stdout.json`

## Scope
- Fresh live resilience benchmark pass with two scenarios:
  - `baseline` (high concurrent CRUD, moderate timeout/concurrency)
  - `burst` (higher concurrency, tighter timeout)
- Measured:
  - Throughput and enrichment coverage
  - Latency percentiles (from `_ai_metadata.latency_ms`)
  - Retries, replayed deliveries, version/hash conflicts, DLQ length
  - Quarantine/SLO counters and execution reason distributions

## Scenario Results
| Scenario | Ops | Errors | Remaining Docs | Enriched | Coverage | p50 ms | p95 ms | p99 ms | Retries | Timeouts | Version Conflicts | DLQ |
|---|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|---:|
| baseline | 360 | 0 | 184 | 9 | 4.89% | 2146 | 7172 | 7558 | 1 | 0 | 10 | 0 |
| burst | 720 | 0 | 376 | 27 | 7.18% | 1904 | 3646 | 3661 | 15 | 15 | 13 | 0 |

## Execution Outcome Snapshot

### baseline (`bench_baseline_agent_v2`)
- `completed`: 9
- `skipped`: 10 (`strict_version_conflict`)
- `failed`: 1 (`pipeline_error`)
- `quarantine_events`: 0

### burst (`bench_burst_agent_v2`)
- `completed`: 27
- `skipped`: 13 (`strict_version_conflict`)
- `failed`: 21 (`timeout`: 15, `pipeline_error`: 6)
- `quarantine_events`: 0

## What Passed
- Runtime stayed up during high concurrency and burst traffic.
- No CRUD-side application errors in the load generator (`errors=0` in both scenarios).
- Retry path, timeout handling, and replay semantics were exercised.
- DLQ stayed at 0 in this run (no hard terminal dead-lettering).
- New phase controls/metrics were active and observable (retry/version conflict/concurrency wait/SLO metrics).

## What Failed / Gaps Found
1. Coverage under strict mode is too low for production enrichment workloads.
- Main reason: `strict_version_conflict` under concurrent updates/deletes.
- Result: majority of surviving docs were not enriched in-window.

2. Prompt template fragility produced pipeline failures.
- Sample failure: `PromptRenderError` due undefined `document._id`.
- Under high-churn events, prompt assumptions must tolerate sparse/partial docs.

3. Burst profile produced meaningful timeout failures.
- `timeout` failures observed with tighter timeout + high concurrency.
- Indicates need for scenario-specific timeout/concurrency tuning per agent class.

## Readiness Verdict
- **Overall verdict: Conditional / Not yet production-ready for strict-mode high-churn enrichment.**
- **Ready components:** queueing, retries, isolation controls, observability plumbing.
- **Blocking behavior:** strict consistency conflicts can suppress most writes in bursty concurrent CRUD workloads.

## Recommended Production Actions (Priority)
1. Define per-use-case consistency defaults.
- Use `strict_post_commit` only where correctness must beat coverage.
- Use `eventual` for enrichment-heavy high-churn collections.

2. Add conflict-resolution strategy for strict mode.
- Option A: auto re-dispatch on `strict_version_conflict` with fresh snapshot.
- Option B: conflict queue with bounded replay policy.

3. Harden prompt templates for partial documents.
- Avoid hard assumptions like `document._id` existing in all matched events.
- Add null-safe template patterns and validation guards.

4. Calibrate timeout/concurrency by agent class.
- Keep external-call timeouts realistic (not ultra-tight), tune retries + concurrency caps from live p95/p99 data.

5. Add pass/fail SLO gates to CI benchmark.
- Minimum coverage target
- Max timeout-rate target
- Max strict-conflict-rate target
- Latency SLO percentile gates

## Phase Completion Summary
- Phase 1 to Phase 6 are implemented to **core** status.
- Remaining work is now mostly policy/tuning/distributed-control hardening rather than missing base mechanisms.
