# Documentation index

This index separates current operational documentation from historical/version-labelled material. A version in an older document title describes the milestone that introduced or last audited that topic; it is not the current RustProxy release identity.

## Current operational entry points

- [INSTALL.md](INSTALL.md) - installation and managed updates.
- [SETTINGS.md](SETTINGS.md) - listeners, response defaults and administration settings.
- [API.md](API.md) and [API_ACCESS.md](API_ACCESS.md) - administration API and access controls.
- [VHOSTS.md](VHOSTS.md), [VHOST_ACCESS.md](VHOST_ACCESS.md), [CUSTOM_LOCATIONS.md](CUSTOM_LOCATIONS.md) - HTTP routing and access behavior.
- [DOCKER_DISCOVERY.md](DOCKER_DISCOVERY.md) - Docker discovery agent and generated vhosts.
- [CACHE.md](CACHE.md) and [CACHE_DIAGNOSTICS.md](CACHE_DIAGNOSTICS.md) - cache semantics and diagnostics.
- [PROMETHEUS.md](PROMETHEUS.md), [HTTP3.md](HTTP3.md), [STREAMS.md](STREAMS.md) - monitoring and transport features.
- [SECURITY.md](SECURITY.md) - current security model and limitations.
- [TEST_REPORT.md](TEST_REPORT.md) - release verification status and explicit environment limitations.
- [0.24.5 specification audit](V0.24.5_AUDIT.md) - HTTP/3 empty-request-body normalization for HTTP/1.1 upstreams and DELETE regression matrix.
- [0.24.4 specification audit](V0.24.4_AUDIT.md) - process-local Linux THP mitigation and memory-retention verification matrix.
- [0.24.3 specification audit](V0.24.3_AUDIT.md) - memory-retention, H3 settings placement and dynamic diagnostics source-vs-spec matrix.
- [0.24.1 specification audit](V0.24.1_AUDIT.md) - current shared-statistics/runtime-metadata/Settings navigation source-vs-spec matrix.
- [0.24.0 specification audit](V0.24.0_AUDIT.md) - historical H2 graceful-shutdown/system-statistics source-vs-spec matrix.
- [0.23.3 specification audit](V0.23.3_AUDIT.md) - historical legacy WebSocket compatibility source-vs-spec matrix.
- [0.23.2 specification audit](V0.23.2_AUDIT.md) - adjustable live-chart history and HTTPS local-CLI/live-log source-vs-spec matrix.
- [0.23.1 specification audit](V0.23.1_AUDIT.md) - historical initial Cache/Transform live-chart source-vs-spec matrix.
- [0.23.0 specification audit](V0.23.0_AUDIT.md) - historical certificate API/live-logs/cache-UX source-vs-spec matrix.
- [Interactive live logs](LIVE_LOGS.md) - `rust-proxy --livelogs`, structured filters, detail view, bounded stream/gap semantics.
- [0.22.3 specification audit](V0.22.3_AUDIT.md) - historical h2c Upgrade/external-certificate audit.
- [0.22.2 specification audit](V0.22.2_AUDIT.md) - historical retry/H2/concurrency source-vs-spec matrix.
- [0.22.1 specification audit](V0.22.1_AUDIT.md) - historical UI/RFC8441/h2c/tunnel source-vs-spec matrix.
- [0.21.0 specification audit](V0.21.0_AUDIT.md) - historical 0.21 source-vs-spec matrix.

## Historical or version-labelled context

These files are retained because they document migrations, original feature contracts or past audits, but their version labels and conclusions must not be treated as a fresh 0.24.1 audit:

| File | Historical marker | Use |
|---|---|---|
| `INTEGRATIONS_040.md` | 0.4.0 | Original integration/forwarding milestone. |
| `MANAGEMENT.md` | updated for 0.4.0 | Early vhost-management behavior and terminology. |
| `SECURITY_AUDIT.md` | 0.7.1 | Historical limited administration-exposure audit; not a current security certification. |
| `MIGRATION.md` | 0.7.3 -> 0.8.0 | Version-specific deployment migration notes. |
| `ACME_RFC2136.md` | 0.5.0 | Original RFC2136 integration notes; current renewal behavior is also documented in `RENEWAL.md`. |
| `TRANSPORT.md` | early transport contract | Background contract; current HTTP/3-specific behavior is in `HTTP3.md`. |

## Screenshots

See [screenshots/README.md](screenshots/README.md). Only two explicitly labelled legacy simulated references remain; stale simulated UI captures were removed in 0.19.1.
