# TenantPilot Documentation Index > **Status:** Active > **Last reviewed:** 2026-04-30 > **Use for:** Navigating current documentation sources and understanding how to maintain them with low overhead > **Do not use for:** Assuming any document is implementation truth without repo verification ## Current Source of Truth - `docs/product/roadmap.md` - current product roadmap and prioritization context - `docs/product/spec-candidates.md` - active spec candidate queue - `docs/product/principles.md` - product and architecture principles - `docs/strategy/product-vision.md` - long-term product vision - `docs/strategy/domain-coverage.md` - domain and coverage strategy ## Product Operations - `docs/product/discoveries.md` - `docs/product/implementation-ledger.md` - `docs/product/prompts/` - `docs/product/standards/` ## Technical Research - `docs/research/` ## UI Standards - `docs/ui/` ## Audits - `docs/audits/` ## Security And Access References - `docs/PERMISSIONS.md` - `docs/security/` ## Historical Or Superseded Material - `docs/audits/archive/` - audit-derived candidate documents that are marked `Historical`, `Superseded`, or `Needs Review` ## Lightweight Maintenance Model - Keep only the current source-of-truth documents actively maintained. - Update a document when the underlying roadmap, policy, or decision actually changes. - Mark older material with status headers instead of rewriting it to feel current. - Prefer archive or superseded markers over deletion. - Verify implementation claims against repo code, specs, and tests. ## Rules For Agents - Treat docs as guidance, not implementation truth. - Verify implementation claims against repo code. - Specs are not automatically implemented. - Tests are not automatically executed. - Historical audits may be outdated. - Prefer current roadmap and spec-candidates for prioritization.
