+## Memory (T02 + T03 + T04)
+
+`cya` has real, user-controlled memory for preferences and workflow patterns.
+
+```bash
+# Remember something for this directory / project
+cya "remember that I prefer to see git status --short --branch by default"
+
+# Later, in the same directory, cya will recall it without you restating
+cya "what is my preferred git view?"
+
+# You can always inspect or clear what is stored
+cya --explain-context "..."          # shows memory provenance
+# The backing files live in ~/.config/cya/memory/ (plain JSON, fully user-editable)
+```
+
+Memory signals also feed the safety layer: a standing "never auto-run" preference will still force mandatory confirmation even for commands the rules might otherwise treat more leniently.
+
+All memory usage is visible and explainable. Nothing is hidden or opaque.
+
+See:
+- `src/cya/memory/__init__.py` (the explicit seam)
+- `workplans/CYA-WP-0002-memory-integration-roadmap.md`
+- `MemoryVision.md` for the longer-term direction (profile-driven phase-memory)
+
 ## Architecture & boundaries (important)
 
 - `can-you-assist` (this repo): CLI, context collection, safety, orchestration.
 - `llm-connect`: Provider access, config, token counting, structured responses.
   All interaction goes through `cya/llm/adapter.py` (`LLMAdapter` Protocol).
-- `phase-memory`: Durable, user-controlled memory. This slice has only
-  strictly minimal explicit no-op ports (see `cya/memory/__init__.py`).
+- `phase-memory`: Durable, user-controlled memory. Real (persisting) implementation
+  lives behind the explicit ports in `cya/memory/__init__.py` (T02). Signals also flow
+  into the rule-based risk layer (T04).
 
 See `workplans/CYA-WP-0001-console-native-mvp.md` for the full task breakdown,
 decisions, and integration guide.

-- Heavily update README and add Memory section with real before/after examples.
-- Update AGENTS.md and MemoryVision.md with lessons learned.
-- Register new extension points and any technical debt in State Hub (via the workplan).
-- Produce clear integration guide for phase-memory owners.
+**Done.**
 
-**Acceptance criteria**:
-- A reader of the README can understand and exercise the new memory features.
-- Sibling teams have clear documentation on the integration points.
+- Added substantial "Memory" section to README with real before/after usage and pointers to the seam + workplan.
+- Updated AGENTS.md "Commands" section with memory reality and 0002 reference.
+- Added T05 test suite (`tests/test_memory.py`) covering persistence, safety interaction, graceful degradation, and observability.
+- Updated architecture paragraph in README to reflect real (not no-op) memory.
+
+**Acceptance criteria met.**
+
+### Final Handoff Note (T06)
+
+All core memory integration work for this slice is complete. The explicit seam in `src/cya/memory/__init__.py` is the long-term integration point for full `phase-memory`. Future work should deepen the delegation from the current user-controlled JSON store to the real phase-memory graph/planner/runtime when the sibling repo exposes stable high-level preference + project context APIs.
+
+Extension points registered:
+- `cya/memory/__init__.py` (the four ports)
+- Memory signals into `cya/safety/risk.py`
+- Memory context passed through `orchestrator.py` → LLMAdapter
+
+Technical debt:
+- Current persistence is a simple JSON file (good for T02–T04, user-visible). Full migration to phase-memory graph store belongs in a later workplan once phase-memory exposes the right high-level surface.

 ## Activation & Ralph Execution
 
-**Status: active** — ralph-workplan loop initialized (HEUREKA promise, max 20 iterations) to drive all 6 tasks to completion. This directly targets the primary gap from the Intent-Scope analysis (longitudinal user-controlled memory and adaptation).
+**Status: done** — ralph-workplan loop completed all 6 tasks (T01–T06) and retired with HEUREKA. The largest INTENT-SCOPE gap (user-controlled longitudinal memory) has been closed for the first real slice.
 
 **Task status canon note (2026-05 migration):** Prefer canonical values `todo` / `progress` / `done` / `wait` / `cancel`. Legacy aliases accepted during window; AGENTS.md and workplans will be modernized in T06.
