-## Abstract
+## Overview
 
-LogSight-AI is a local-first Python CLI that parses common log formats, summarizes error patterns, flags message-length outliers, and identifies elevated error-rate windows. Its production package does not transmit logs or require credentials. The detector is an explainable statistical heuristic—not a trained incident classifier, root-cause system, or measured accuracy claim.
+LogSight-AI is a local-first log analysis and anomaly-detection platform that is being extended from a deterministic CLI into a production-oriented observability stack. The original parser/analyzer remains dependency-light and explainable; enterprise integrations are optional and isolated behind adapters.
 
-## Formal detection logic
+## Enterprise architecture
 
-For $N$ parsed entries with message lengths $\ell_i$, the analyzer computes the population mean $\mu$ and population standard deviation $\sigma$. When $\sigma>0$, it flags a length outlier only when

-\]
+### Five production layers
 
-Separately, ERROR and CRITICAL entries are flagged by a direct rule. For each complete, non-overlapping window of $W$ entries, it reports an error-rate spike when
+1. **Ingestion & streaming** — bounded async streams plus an optional Kafka/Redpanda adapter. Deploy Vector or Fluent Bit at the edge for collection and metadata enrichment.
+2. **AI & anomaly detection** — deterministic template/frequency signals are available now. The adapter boundary supports Drain3, Sentence-Transformers/LogBERT, ONNX Runtime, and future learned detectors without replacing the core API.
+3. **Storage & search** — ClickHouse event storage and Qdrant vector storage adapters are included; Redis is reserved for caching, deduplication, and rate limiting.
+4. **Observability & MLOps** — OpenTelemetry span helpers and Prometheus-compatible `/metrics` are included. Model/data-drift tooling can be attached to the normalized event stream.
+5. **Delivery & alerting** — `WebhookNotifier` provides a minimal outbound contract for Slack, PagerDuty, Discord, or an internal incident gateway.
 
-\[
-r_j=\frac{e_j}{W}\geq\tau_r,\qquad W=100,\quad \tau_r=0.25\ \text{by default}.
-\]
+## New enterprise interfaces
 
-These definitions map directly to [logsight/analyzer.py](logsight/analyzer.py); zero-variance message lengths receive no z-score, and partial trailing windows are intentionally excluded. Read the complete [mathematical foundations](docs/MATHEMATICAL_FOUNDATIONS.md) and [complexity analysis](docs/COMPLEXITY_ANALYSIS.md).
+- `logsight.enterprise.EnrichedLog` — normalized event schema with service/source/host, trace ID, span ID, template, fingerprint, and attributes.
+- `logsight.enterprise.extract_template()` — dependency-free template baseline; replace with Drain3 for high-cardinality production parsing.
+- `logsight.enterprise.semantic_features()` — deterministic feature baseline; explicitly **not** represented as a learned embedding.
+- `logsight.streaming.InMemoryStream` — bounded local async stream for tests and development.
+- `logsight.streaming.KafkaStream` — optional Kafka/Redpanda producer using `aiokafka`.
+- `logsight.storage.ClickHouseStore` and `QdrantStore` — HTTP adapters for durable analytical and semantic storage.
+- `logsight.api` — optional FastAPI gateway with `/health`, `/metrics`, `/v1/logs`, `/v1/logs/batch`, and `/v1/logs/recent`.
+- `logsight.observability.span()` — no-op-safe OpenTelemetry instrumentation helper.

-| Mean throughput | 96.21 pipeline runs/s | Same 1,000-line local workload |
-| Detection threshold | z-score > 2.5 | Fixed default policy, not a calibrated significance level |
-| Spike threshold | error rate >= 0.25 in 100 entries | Fixed default policy, not a learned decision boundary |
+The base project still runs without external services. To launch the reference enterprise stack:
 
-The dated measurements are recorded in [benchmarks/benchmark_report.md](benchmarks/benchmark_report.md). CI generates and retains per-commit benchmark JSON; compare only like-for-like Python, hardware, workload, and warm-up configurations. No labeled incident dataset or precision/recall result is committed.
-
-## Research questions
+```bash
+docker compose -f docker-compose.enterprise.yml up --build
+```
 
-1. What precision, recall, and alert burden do error-level, z-score, and error-rate rules produce on a versioned labeled corpus?
-2. How do non-overlapping, overlapping, and time-based windows trade detection delay against false alerts?
-3. How stable are fixed thresholds across formats, services, and message-length distributions?
-4. How do parsing and analysis latency scale with line count, line length, and unique-message cardinality?
+Services exposed locally:
 
-The [academic audit](docs/ACADEMIC_AUDIT.md) documents the repository's direct algorithmic strengths, evidence boundaries, and next experiments.
+| Service | Port | Purpose |
+|---|---:|---|
+| LogSight API | 8000 | Async ingestion/API gateway |
+| Redpanda | 9092 | Streaming buffer |
+| ClickHouse | 8123 | Log analytics/storage |
+| Qdrant | 6333 | Vector similarity search |
+| Redis | 6379 | Cache/dedup/rate limiting foundation |

-## Architecture
+Install optional Python integrations with:
 
-```mermaid
-flowchart LR
-    A["File or stdin"] --> B["Format parser"]
-    B --> C["Typed LogEntry records"]
-    C --> D["Statistics and anomaly analysis"]
-    D --> E["Rich CLI report"]
+```bash
+pip install -e ".[api,kafka,observability,ai,parsing]"
 ```
 
-Supported formats include ISO-8601 application logs, syslog, nginx access logs, and generic level-prefixed lines. Detection is an explainable statistical heuristic; it is not a trained model and no accuracy claim is made without a labeled evaluation corpus.
-
-## Evidence-backed reasoning
+The optional integrations are deliberately separated so a developer can use the original local-first CLI without downloading heavyweight ML or infrastructure clients.
 
-The optional `--explain` flag turns existing detector output into concise, user-facing evidence statements. Each statement identifies its direct or statistical basis: parsed error level, message-length z-score with its configured threshold, or observed error count/rate in a complete analysis window. Each statement also reports a deterministic support level: `single-signal` for one detector signal and `corroborated` when the same entry meets both error-level and statistical criteria. LogSight does not infer an incident root cause, use an LLM, send logs externally, or report a model-confidence score.
+## Current detection contract
 
-```bash
-logsight analyze application.log --window 200 --spike-threshold 0.20 --explain
-cat application.log | logsight stdin --explain
-```
+The original analyzer uses explainable statistical heuristics: message-length z-score outliers, direct ERROR/CRITICAL rules, and elevated error-rate windows. These are not presented as calibrated incident probabilities. The enterprise layer preserves that evidence-first behavior while adding normalized event context and pluggable AI interfaces.
 
 ## Quick start
 
 ```bash
 python -m venv .venv
-source .venv/bin/activate  # Windows: .venv\Scripts\activate
+source .venv/bin/activate  # Windows: .venv\\Scripts\\activate
 pip install -e .
 logsight health
-logsight analyze application.log
-cat application.log | logsight stdin
+logsight analyze application.log --explain
 ```
 
-Useful controls:
-
-```bash
-logsight analyze application.log --threshold 3.0 --window 200 --spike-threshold 0.20
-```
-
-## Verified metrics
-
-Measured locally on 2026-07-17; CI artifacts are the canonical per-commit record.
-
-| Metric | Value |
-|---|---:|
-| Automated tests | 50 passing |
-| Core package coverage | 95.26% |
-| Benchmark input | 1,000 lines |
-| Median pipeline latency | 10.315 ms |
-| Mean throughput | 96.21 runs/sec |
-| Approximate line throughput | 96,213 lines/sec |
-| Security findings | Pending CI security job |
-| Docker image size | Pending CI build |
-
-Results vary by hardware and Python version. See [Benchmark Guide](docs/BENCHMARKING.md) and [Benchmark Report](benchmarks/benchmark_report.md).
-
 ## Engineering controls
 
-Every pull request runs formatting, linting, strict type checking, unit/integration/CLI tests, a 90% coverage gate, package and container validation, Bandit, dependency audit, SBOM generation, CodeQL, and a reproducible microbenchmark. Checks fail closed.
+Pull requests retain the existing formatting, linting, strict typing, unit/integration/CLI tests, coverage gate, package/container validation, Bandit, dependency audit, SBOM, CodeQL, and reproducible benchmark controls. Enterprise changes should include contract tests for adapters and load tests before production rollout.
+
