+## 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:

 ## 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.

-- Ensure memory cannot be used to bypass safety.
+**Done (verified).**
 
-**Acceptance criteria**:
-- Memory-influenced suggestions still respect the mandatory confirmation rules.
-- Tests cover memory + safety interaction.
+- Extended `classify()` (backward-compatible `memory: dict | None` param) + added `_apply_memory_signals` helper.
+- Memory signals can append rationale / force `requires_confirmation=True` for matching "never" prefs.
+- Hard invariant preserved: memory **never** downgrades a non-SAFE level or clears confirmation (proven by test).
+- Wired the call in orchestrator (T03 already had memory in scope).
+- Live verification: destructive + "never_auto_run" memory → still requires confirmation; approved signals add friendly note only.

+
+### 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.
