Code Review
This is an impressive pull request that significantly moves the project towards production readiness. The introduction of a CI/CD pipeline, pre-commit hooks, and extensive documentation for contributing, operations, and architecture is a huge step forward. The new modules for observability, security, performance, and feature flagging are well-designed and crucial for a production system. My review focuses on a few areas for improvement to further enhance the robustness and security of these new additions.

There was a problem hiding this comment.
There's a potential division-by-zero error here if $baseline_error_rate is 0. The bc command will fail, and due to 2>/dev/null || echo "0", the error_multiplier will be incorrectly set to 0. This would mask a transition from a zero-error state to a non-zero error state. You should handle the case where the baseline is zero explicitly to correctly flag any new errors.

The fallback for generating random bytes uses Math.random(), which is not cryptographically secure and should not be used for generating secrets. For a Node.js environment, you should use the built-in crypto module as a secure fallback. Please add import { randomBytes as nodeRandomBytes } from 'crypto'; at the top of the file to support the suggested change.
const randomBytes =
typeof crypto !== 'undefined' && crypto.getRandomValues
? crypto.getRandomValues(new Uint8Array(length))
: nodeRandomBytes(length);| ``` | ||

This project structure diagram is very helpful, but it seems to be missing the new top-level directories introduced in this PR, such as features, observability, performance, and security. Please update the diagram to reflect the new, more modular structure.

The script attempts to write a rollback report to /var/log/. This directory is often restricted to the root user and may not be writable by the user running the script, which could cause this step to fail. Consider making the log directory configurable via an environment variable or writing to a local logs directory within the project instead for better portability.

There was a problem hiding this comment.
The Prometheus exporter writes histogram samples as ${metric.name}{${label}} ${value} for every entry in the Map (src/observability/metrics.ts L132‑135). Because Histogram.updateBuckets stores buckets as labels like le="100", plus sum and count, the exporter emits metrics such as agent_task_duration_ms{sum} 123 and agent_task_duration_ms{le="100"} 5. Prometheus expects histogram series to be exposed as separate metrics with _bucket, _sum, and _count suffixes (e.g. agent_task_duration_ms_bucket{le="100"}), so the current output is rejected by Prometheus and the “Prometheus-compatible” metrics endpoint cannot be scraped. Please emit bucket counts under metric_name_bucket, the cumulative sum under metric_name_sum, and the sample count under metric_name_count (with the proper {le="…"} label for buckets).

Review complete for PR #36. No blocking issues were identified; the CI/CD pipeline, observability stack, and production runbooks look consistent with the current implementation and exported metrics.
