+# PyAutoMemory — Agent Guidance
+
+PyAutoMemory is the **Memory organ** of the PyAuto organism: long-term
+knowledge — *what the science says*. Literature wikis, concepts, entities,
+bibliographies. (The organs and boundaries are defined once in
+`PyAutoBrain/ORGANISM.md`.)
+
+## The read contract
+
+Memory is **pull-only, on demand** — no agent queries it automatically. Consult
+it when the work is scientific or a plan names a domain (lensing, SMBH,
+CTI/Euclid, inference methods, galaxy evolution); skip it entirely for
+packaging, tooling, and workflow tasks.
+
+When you do read:
+
+1. **Index first.** Start at [`index.md`](index.md), then the relevant
+   sub-wiki's own `index.md` (`lensing_wiki/`, `smbh_wiki/`, `cti_wiki/`,
+   `methods_wiki/`, `galaxies_wiki/`).
+2. **Then at most 2–3 pages.** Read only the concept/entity/source pages the
+   index points you to. **Never bulk-load a sub-wiki.**
+3. **Do not couple to the internal layout** — reach pages through the indexes,
+   not hard-coded paths.
+
+## What does NOT live here
+
+- **Operational history** — what the organism *did* (prior tasks, decisions,
+  failed approaches) lives in **PyAutoMind** (`complete.md`, GitHub issues),
+  not here. Memory = what the science says; Mind = what the organism did.
+- **Workflow state, health, execution** — Mind / Heart / Build respectively.
+
+## This repo is personal
+
+PyAutoMemory contains personal research material. **Never reference or copy
+PyAutoMemory content into public or user-facing repos** (libraries,
+workspaces, tutorials, assistants).

 ## The organism
 
-PyAutoMemory is one organ of the PyAuto organism; each repo has one job:
-
-| Organ | Repo | Role |
-|-------|------|------|
-| **Mind** | PyAutoMind | Decides *what* should be done — intent, goals, future work. |
-| **Brain** | PyAutoBrain | Figures out *how* — reasoning, planning, orchestration. |
-| **Hands** | PyAutoBuild | Builds and releases the software. |
-| **Heart** | PyAutoHeart | Determines whether the organism is healthy. |
-| **Memory** | **PyAutoMemory** (this repo) | Stores what the organism has learned — long-term knowledge. |
+PyAutoMemory is the Memory organ of the PyAuto organism — it stores what the
+organism has learned. The organs and their boundaries are defined once in
+`PyAutoBrain/ORGANISM.md`; how agents should read this repo is defined in
+[`AGENTS.md`](AGENTS.md).
