# P4P Wiki > Machine-readable index of the P4P platform wiki, for AI agents built on or > integrated with the P4P platform (see /for-agents/ on this site for the full > convention). Each line links to one module or capability doc. Fetch the > linked page for details: YAML frontmatter (routes, permissions, entities, > related ADRs) followed by human-readable sections per page in that module. ## Overview - [What is P4P](/overview/what-is-p4p): The ecosystem platform vision — Organizations, Users, Products. - [Architectural tiers](/overview/architectural-tiers): The User / Organization / Platform tiers and how routes map to them. - [Glossary](/overview/glossary): Terms used consistently across this wiki and the codebase. ## Modules - [IAM](/modules/iam): Authentication (password, magic link, OTP, Google OAuth), organizations, roles & permissions, invitations, impersonation, audit log. - [Platform Administration](/modules/platform-admin): Platform-tier management of organizations, users, products, subscriptions, platform roles, and platform staff invitations. - [Staffing](/modules/staffing): P4P's internal PM tool — departments, employees, projects, tasks, task statuses, HR pool applicant pipeline, shared documents. Platform-tier, not organization-tier. - [Finance](/modules/finance): Owner ledger (records/reports/reconciliation), per-department books (leader-only), project finance slice, and per-task payout offers with payment confirmation. Platform-tier, own `platform:finance:*` permission scope separate from `staffing:*`.
