Corrections keep their history and provenance. * **Wiki pages** turn related facts and notes into readable Markdown. Facts are the evidence. Pages are the useful view. Memory ## Facts Good facts include preferences, decisions, relationships, reusable procedures, and significant events. Temporary chatter and guesses do not belong here. Arden can create, amend, supersede, expire, or retract a fact. It never needs to erase history to correct one. ## Wiki pages The Memory view has two ways to browse the same pages: * **Files** shows their managed paths and directory structure. * **Notebook** shows page titles and a reading-oriented view. Open a page to edit it, inspect links and cited records, or restore an earlier revision. Agents use paths such as `topics/reinforcement-learning.md`; internal page IDs and revision hashes stay inside the backend. Each directory can have a `README.md` that explains what belongs there and how agents should use it. It is guidance, not a generated file listing. Arden loads a small resident context from root pages such as `README.md`, `directives.md`, `me.md`, and `profile.md` when they exist. It retrieves other pages when they are relevant. Interactive agents can create, edit, move, and archive ordinary pages through the normal approval flow. Scheduled automations can write only below `automations/` unless you grant a different supported workflow. ## Maintenance Memory Maintenance reviews facts. Memory Synthesis updates fact-backed pages. Wiki Maintenance keeps page structure, links, titles, and metadata healthy. Every change is versioned and reversible.
