# RustProxy documentation index

This is the canonical index for the current project documentation. The authenticated administration documentation page at `/docs` embeds these Markdown files in its **Reader** tab and keeps OpenAPI/Swagger in a separate **API** tab.

## Historical or version-labelled context

Version-labelled `V*.md` files are retained as historical implementation/audit records. Their version number describes the audited milestone. The current release implementation note is [V0.26.5_IMPLEMENTATION.md](V0.26.5_IMPLEMENTATION.md); [V0.26.4_IMPLEMENTATION.md](V0.26.4_IMPLEMENTATION.md) is retained as the prior administration/backend-lifecycle milestone, [V0.26.3_IMPLEMENTATION.md](V0.26.3_IMPLEMENTATION.md) as the prior appearance/UI milestone, [V0.26.2_IMPLEMENTATION.md](V0.26.2_IMPLEMENTATION.md) as the prior Logs/UI milestone and [V0.26.1_IMPLEMENTATION.md](V0.26.1_IMPLEMENTATION.md) as the prior protocol-attribution milestone. The latest retained audit is [V0.25.5_AUDIT.md](V0.25.5_AUDIT.md); older audit files remain historical evidence.

Older context documents such as [INTEGRATIONS_040](INTEGRATIONS_040.md), [MANAGEMENT](MANAGEMENT.md), [SECURITY_AUDIT](SECURITY_AUDIT.md), [ACME_RFC2136](ACME_RFC2136.md) and older version audits remain available for traceability but should not override the current functional/technical documents above.

The pre-cleanup developer-level changelog is retained as [CHANGELOG_TECHNICAL_ARCHIVE](CHANGELOG_TECHNICAL_ARCHIVE.md) when low-level historical detail is needed. The root `CHANGELOG.md` remains the operator-facing release record.
Completed roadmap history is retained separately as [ROADMAP_HISTORY](ROADMAP_HISTORY.md); the root `ROADMAP.md` contains only the active 0.25 milestone, release gate and future direction.

## Maintenance rules

- Put user/operator-visible release changes in `CHANGELOG.md`.
- Put future release scope in `ROADMAP.md` and unresolved work in `docs/TODO.md`.
- Keep detailed implementation evidence in technical documents or version audits, not in CHANGELOG.
- When functionality changes, update the functional document, this index, Reader coverage and cross-links in the same change.
- Remove obsolete or duplicated documents when they no longer provide historical or technical value; retain useful audits with an explicit historical label.
