+# RALPH LOOP PROMPT — Memory Subsystem Evolution (MemGPT + Mem0 + Mem0g-light)
+
+> **How to run:**
+> ```
+> /ralph-loop "Implement the memory evolution exactly as specified in docs/PROMPT-memory-evolution.md. ALWAYS start each iteration by invoking the /caveman:caveman ultra skill at intensity 'full'. Output <promise>MEMORY EVOLUTION COMPLETE</promise> when all phases pass lint + tests." --max-iterations 40 --completion-promise "MEMORY EVOLUTION COMPLETE"
+> ```
+
+---
+
+## MANDATORY PER-ITERATION PREAMBLE
+
+**Every iteration MUST begin with these two actions, in order:**
+
+1. **Activate caveman mode.** Invoke the `caveman:caveman ultra` skill at intensity `full` before any other tool call. All prose you emit during the iteration must follow caveman rules (drop articles, fragments OK, no filler, no pleasantries). Code/commits/PRs stay normal per caveman plugin rules.
+2. **Read this file in full** (`docs/PROMPT-memory-evolution.md`) to re-anchor on the plan.
+
+If caveman already active from prior iteration, re-assert it anyway — ralph loop restarts cold each time.
+
+After preamble:
+
+3. Inspect repo state: check which tasks already done by reading target files / running grep.
+4. Pick next incomplete task in phase order (Phase 1 → 2 → 3 → 4 → 5). No skipping, no out-of-order.
+5. Implement task.
+6. Run relevant lint + tests for that phase before exit.
+7. When ALL phases complete AND lints + tests green → output `<promise>MEMORY EVOLUTION COMPLETE</promise>`.
+
+**DO NOT** implement multiple phases in one iteration unless they are tiny edits in the same file.
+
+---
+
+## LINT + TEST COMMANDS
+
+Run after each phase:
+- Backend lint: `cd api && ruff check . --fix`
+- Backend tests: `cd api && pytest -q`
+- Frontend lint: `cd adiuvAI && npx eslint . --fix`
+- Frontend typecheck: `cd adiuvAI && npx tsc --noEmit`
+
+---
+
+## SOURCE OF TRUTH
+
+Architectural rationale lives in [docs/memory-evolution-strategy.md](docs/memory-evolution-strategy.md). This file is the execution plan derived from it. If a conflict appears, the strategy doc wins on *why*, this doc wins on *how*.
+
+**Zero-trust invariant:** all user-content writes/reads go through per-user Fernet in [api/app/core/memory_middleware.py](api/app/core/memory_middleware.py). Backend never stores plaintext user content. Embeddings may leak text to OpenAI — already accepted trade-off, documented in privacy policy.
+
+**Tier gates** live in [api/app/billing/tier_manager.py](api/app/billing/tier_manager.py). New capabilities MUST be gated there, not ad-hoc in routes.
+
+---
+
+## WHAT THIS FEATURE DOES
+
+Five goals from the strategy doc, executed in order:
+
+1. **Activate real pgvector** on `associative` tier (replace keyword fallback). Pro+ only.
+2. **Mem0-style Extract/Update pipeline** post-`store_episode`. Batch for Free, realtime for Pro+.
+3. **`relational` tier (Mem0g-light)**: new table `memory_relations` — person/project/topic graph in Postgres.
+4. **Settings > Memory UI** in Electron renderer — view/edit `core` + `relational`, GDPR forget.
+5. **Proactive mining** (Power tier only, optional last): scheduled job promotes episodic patterns to `proactive`.
+
+**Architectural anchors already in place** (do NOT re-create):
+- `MemoryMiddleware.enrich_context` injects 4 tiers into orchestrator — extend, not replace.
+- `MemoryAssociative.embedding` column exists (JSON fallback); swap to `pgvector.Vector(1536)` in migration.
+- `get_llm("gpt-4o-mini", ...)` in [api/app/core/llm.py](api/app/core/llm.py) is canonical LLM factory.
+- Tier-gating helper: `TierManager.has_feature(user, feature)` — add new feature enums.
+
+---
+
+## PHASE 1 — pgvector on associative tier (Pro+ gated)
+
+### TASK 1.1: Alembic migration — switch `memory_associative.embedding` to `vector(1536)`
+
+**File:** `api/alembic/versions/XXX_associative_pgvector.py` (new)
+
+Contents:
+- `CREATE EXTENSION IF NOT EXISTS vector;` (idempotent).
+- `ALTER TABLE memory_associative ALTER COLUMN embedding TYPE vector(1536) USING embedding::text::vector;` — must handle existing JSON rows. If conversion risky, drop column and re-add: `DROP COLUMN embedding; ADD COLUMN embedding vector(1536);` (data loss acceptable — keyword fallback still works).
+- Create IVFFlat index: `CREATE INDEX memory_associative_embedding_idx ON memory_associative USING ivfflat (embedding vector_cosine_ops) WITH (lists = 100);`
+- `downgrade()` reverses: drop index, `ALTER TYPE ... TYPE jsonb`.
+
+Revision id: increment from latest in `api/alembic/versions/`. Check `004_add_memory_tables.py` for style.
+
+**Done signal:** Migration applies cleanly on a fresh DB: `alembic upgrade head` exits 0.
+
+---
+
+### TASK 1.2: Update `MemoryAssociative.embedding` SQLAlchemy column
+
+**File:** [api/app/models.py](api/app/models.py)
+
+Replace:
+```python
+embedding: Mapped[list | None] = mapped_column(JSON, nullable=True)
+```
+with:
+```python
+from pgvector.sqlalchemy import Vector
+...
+embedding: Mapped[list | None] = mapped_column(Vector(1536), nullable=True)
+```
+
+Add `pgvector>=0.2.5` to `api/requirements.txt` (or `pyproject.toml` — check which is authoritative).
+
+**Done signal:** `pgvector` import resolves, `pytest -q` still green on model import.
+
+---
+
+### TASK 1.3: Add `TierFeature.REAL_EMBEDDINGS` feature flag
+
+**File:** `api/app/billing/tier_manager.py`
+
+Add to the feature enum / matrix:
+- `REAL_EMBEDDINGS = "real_embeddings"` → granted for `pro`, `power`, `team`. Free = False.
+
+**Done signal:** `TierManager.has_feature(user, "real_embeddings")` returns correct bool per tier.
+
+---
+
+### TASK 1.4: Embedding helper
+
+**File:** `api/app/core/embeddings.py` (new)
+
+```python
+async def embed_text(text: str) -> list[float] | None:
+    """Call OpenAI text-embedding-3-small. Return None on failure (caller falls back to keyword)."""
+```
+
+Use `AsyncOpenAI` client (already a dep via LiteLLM). Truncate input to 8000 chars. On any exception log warning + return None — MUST not raise.
+
+**Done signal:** Unit test `test_embed_text_returns_1536_floats` passes with mocked client.
+
+---
+
+### TASK 1.5: Wire embeddings into `_load_associative` + `store_associative`
+
+**File:** [api/app/core/memory_middleware.py](api/app/core/memory_middleware.py)
+
+In `_load_associative`:
+1. Check user tier via `TierManager.has_feature(user, "real_embeddings")`.
+2. If True → `embed_text(message)` → if vector not None run:
+   ```sql
+   SELECT * FROM memory_associative
+   WHERE user_id = :uid
+   ORDER BY embedding <=> :qvec
+   LIMIT :k;
+   ```
+   Use SQLAlchemy `embedding.cosine_distance(qvec)` (pgvector).
+3. Fallback (False or None): keep current keyword-order path.
+
+Add new `store_associative(user_id, content)` method:
+- Encrypt content with user Fernet.
+- If tier has real_embeddings → compute embedding, store alongside.
+- Else → store with `embedding=NULL` (still useful for future upgrade).
+
+**Done signal:** Associative search returns semantically-closer results on a pro test user, keyword-ordered for free user.
+
+---
+
+### TASK 1.6: Phase 1 checks
+
+- `cd api && ruff check . --fix`
+- `cd api && pytest -q tests/test_memory_middleware.py` (create minimal test if absent).
+- Manual smoke: spin up docker compose, insert two associative memories via pro user, query → verify cosine ordering.
+
+**Done signal:** All three green.
+
+---
+
+## PHASE 2 — Mem0-style Extract/Update pipeline
+
+### TASK 2.1: Extraction prompt + schema
+
+**File:** `api/app/core/memory_extraction.py` (new)
+
+Define Pydantic models:
+```python
+class MemoryCandidate(BaseModel):
+    type: Literal["fact", "preference", "relation", "routine"]
+    content: str              # short canonical statement
+    target_tier: Literal["core", "associative", "relational", "proactive"]
+    subject: str | None = None     # only for relation
+    predicate: str | None = None   # only for relation
+    object: str | None = None      # only for relation
+    confidence: float = 0.7
+
+class ExtractionResult(BaseModel):
+    candidates: list[MemoryCandidate]
+```
+
+Prompt template (system): "You are a memory extractor for a personal AI secretary. Given the last turn + core memory + recent episodes, identify durable facts, preferences, routines, and person/project relations. Output JSON matching the schema. Skip small talk. Max 5 candidates per turn."
+
+Use `gpt-4o-mini`, `temperature=0`, `response_format={"type": "json_object"}`.
+
+**Done signal:** Calling `extract_candidates(last_turn, core, recent)` on a fixture returns a valid `ExtractionResult`.
+
+---
+
+### TASK 2.2: Update decision (ADD / UPDATE / DELETE / NOOP)
+
+**File:** `api/app/core/memory_extraction.py` (same file)
+
+```python
+async def decide_action(
+    candidate: MemoryCandidate,
+    existing: list[str],   # plaintext neighbours (top-3 by similarity in target tier)
+) -> Literal["ADD", "UPDATE", "DELETE", "NOOP"]:
+```
+
+Uses a second `gpt-4o-mini` call with small prompt: "Given candidate and existing memories, decide ADD / UPDATE / DELETE / NOOP. Return only the verb."
+
+Heuristic short-circuit: if `existing` empty → ADD without LLM (save cost).
+
+**Done signal:** Unit tests for all 4 branches pass with mocked LLM.
+
+---
+
+### TASK 2.3: Pipeline orchestrator
+
+**File:** `api/app/core/memory_extraction.py` (same file)
+
+```python
+async def run_extraction(
+    db: AsyncSession,
+    user_id: str,
+    last_user_msg: str,
+    last_assistant_msg: str,
+    session_id: str | None,
+) -> None:
+```
+
+Steps:
+1. Load small context: `core_memory` + last 5 episodes (via middleware helpers).
+2. `extract_candidates(...)`.
+3. For each candidate: similarity-search target tier → top-3 neighbours → `decide_action` → apply via `MemoryMiddleware.update_core` / `store_associative` / (new) `upsert_relation` / `store_proactive`.
+4. Log Langfuse trace with `trace_id`.
+5. MUST not raise — wrap in try/except, log warning.
+
+**Done signal:** Calling `run_extraction` on a fake "user said my CFO is Giulia" produces a relation candidate and a core candidate, and writes them.
+
+---
+
+### TASK 2.4: Tier-gated dispatch
+
+**File:** [api/app/core/memory_middleware.py](api/app/core/memory_middleware.py)
+
+After `store_episode` success, dispatch extraction:
+- Pro / Power / Team → schedule realtime task (`asyncio.create_task(run_extraction(...))` — fire-and-forget, exceptions swallowed).
+- Free → enqueue a daily-batch marker row (new table `extraction_queue(user_id, episode_id, created_at)`). A separate cron (Phase 5 stub OK) drains it.
+
+Add `TierFeature.REALTIME_EXTRACTION` to tier_manager (Free=False).
+
+**Done signal:** Pro user triggers realtime task (verified via log line); Free user gets queue row.
+
+---
+
+### TASK 2.5: Phase 2 checks
+
+- `cd api && ruff check . --fix`
+- `cd api && pytest -q tests/test_memory_extraction.py`
+
+---
+
+## PHASE 3 — `relational` tier (Mem0g-light)
+
+### TASK 3.1: Alembic migration — `memory_relations` table
+
+**File:** `api/alembic/versions/XXX_memory_relations.py` (new)
+
+```sql
+CREATE TABLE memory_relations (
+  id UUID PRIMARY KEY,
+  user_id UUID NOT NULL REFERENCES users(id),
+  subject_label VARCHAR(128) NOT NULL,        -- canonical label (e.g. "Giulia")
+  subject_type VARCHAR(32) NOT NULL,          -- 'person' | 'company' | 'project' | 'topic'
+  predicate VARCHAR(64) NOT NULL,             -- 'works_at' | 'reports_to' | 'stakeholder_of' | 'last_contacted_on' | 'owes_followup' | custom
+  object_label VARCHAR(128) NOT NULL,
+  object_type VARCHAR(32) NOT NULL,
+  confidence FLOAT NOT NULL DEFAULT 0.7,
+  source_episode_id UUID NULL REFERENCES memory_episodic(id),
+  notes_encrypted BYTEA NULL,                 -- Fernet, optional per-user commentary
+  created_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+  updated_at TIMESTAMPTZ NOT NULL DEFAULT NOW(),
+  last_confirmed_at TIMESTAMPTZ NULL          -- used by TTL decay
+);
+CREATE INDEX memory_relations_user_subject_idx ON memory_relations(user_id, subject_label);
+CREATE INDEX memory_relations_user_predicate_idx ON memory_relations(user_id, predicate);
+```
+
+**Done signal:** `alembic upgrade head` clean.
+
+---
+
+### TASK 3.2: `MemoryRelation` ORM model
+
+**File:** [api/app/models.py](api/app/models.py)
+
+Mirror the table above. `subject_label` / `object_label` are **plaintext** (entity names — treated as identifiers, not content). `notes_encrypted` uses Fernet like other tiers.
+
+**Done signal:** Import of `MemoryRelation` resolves.
+
+---
+
+### TASK 3.3: Relational middleware methods
+
+**File:** [api/app/core/memory_middleware.py](api/app/core/memory_middleware.py)
+
+Add:
+- `async def upsert_relation(user_id, subject, subject_type, predicate, object_, object_type, *, confidence=0.7, source_episode_id=None, notes=None) -> None`
+- `async def query_relations(user_id, subject=None, predicate=None, object_=None, limit=20) -> list[MemoryRelation]`
+- Extend `enrich_context` return dict with key `relational_memory` — list of short strings `"{subject} --{predicate}--> {object}"` filtered by recent/confident (top 10).
+- Tier-gate: Free tier → skip (empty list). Pro = base (person/project predicates only). Power = all predicates incl. custom. Use new `TierFeature.RELATIONAL_MEMORY`.
+
+**Done signal:** Unit tests: upsert then query returns row; tier gating enforces limits.
+
+---
+
+### TASK 3.4: Orchestrator prompt injection
+
+**File:** `api/app/core/deep_agent.py`
+
+Where `core_memory` / `episodic` already injected into system prompt, add a new paragraph labelled **"Known people & projects:"** listing the `relational_memory` strings. Keep under 800 chars (truncate if longer).
+
+**Done signal:** Running a turn with seeded relations — agent uses the info (verified via Langfuse trace + test).
+
+---
+
+### TASK 3.5: Hook into extraction pipeline
+
+**File:** `api/app/core/memory_extraction.py`
+
+When `candidate.type == "relation"` → call `upsert_relation(...)` instead of `update_core` / `store_associative`.
+
+**Done signal:** End-to-end test: turn saying "Marco is the PM on Project Acme" produces a `person --stakeholder_of--> project` row.
+
+---
+
+### TASK 3.6: TTL + decay job
+
+**File:** `api/app/core/memory_extraction.py` (or new `memory_maintenance.py`)
+
+```python
+async def decay_relations(db, user_id) -> None:
+    # confidence *= 0.95 every 30 days since last_confirmed_at
+    # delete rows with confidence < 0.2
+```
+
+Wire into the same daily batch cron as Free extraction (Phase 5 introduces scheduler — OK to define function now and call it from a stub).
+
+**Done signal:** Function exists + has unit test on a seeded fixture.
+
+---
+
+### TASK 3.7: Phase 3 checks
+
+- `cd api && ruff check . --fix`
+- `cd api && pytest -q tests/test_memory_relations.py`
+
+---
+
+## PHASE 4 — Settings > Memory UI (Electron renderer)
+
+### TASK 4.1: Backend endpoints for UI
+
+**File:** `api/app/api/routes/auth.py` (memory sub-section) or new `api/app/api/routes/memory.py`
+
+Routes (all `@require_auth`, return user-scoped data only):
+- `GET /auth/me/memory/core` → `dict[str, str]` (plaintext, decrypted).
+- `GET /auth/me/memory/relational` → `list[RelationOut]` (subject/pred/obj/confidence/last_confirmed_at).
+- `PATCH /auth/me/memory/relational/{id}` → edit label/confidence; body validates predicate ∈ allowed set.
+- `DELETE /auth/me/memory/relational/{id}` → hard delete (GDPR Art. 17).
+- `DELETE /auth/me/memory/core/{key}` → remove a core k/v.
+- `POST /auth/me/memory/forget-all` → wipe all 4 tiers for user; audit log entry. Requires `X-Confirm: true` header — reject 400 otherwise. Do NOT delete the User row.
+
+**Done signal:** OpenAPI schema shows all 6 routes; pytest green.
+
+---
+
+### TASK 4.2: tRPC + auth-manager wrappers
+
+**File:** [adiuvAI/src/main/auth/auth-manager.ts](adiuvAI/src/main/auth/auth-manager.ts) + [adiuvAI/src/main/router/index.ts](adiuvAI/src/main/router/index.ts)
+
+Add auth-manager methods (6) wrapping each HTTP endpoint. Add tRPC procedures in a new `memoryRouter` merged into app router.
+
+**Done signal:** `trpc.memory.listRelational.useQuery()` resolves from renderer.
+
+---
+
+### TASK 4.3: `MemorySection` settings page
+
+**File:** `adiuvAI/src/renderer/components/settings/MemorySection.tsx` (new)
+
+Sections in order:
+1. **Core preferences** — table of k/v from `trpc.memory.getCore`. Each row: key, value, edit pencil (inline input), trash icon (`deleteCore`). Add-row form at bottom.
+2. **People & relationships** — table of relations. Columns: subject, predicate (select), object, confidence (progress bar), last confirmed (formatted via `formatRow`). Pencil → edit in drawer. Trash → `deleteRelation`.
+3. **Danger zone** — red Card with "Forget everything" button. Confirm dialog (typed "forget" to enable) → calls `forgetAll` with `X-Confirm: true`.
+
+Wire into `SECTIONS` in [adiuvAI/src/renderer/components/settings/types.ts](adiuvAI/src/renderer/components/settings/types.ts) as `{ id: 'memory', label: 'Memory', icon: Brain }`. Use `Brain` from `lucide-react`.
+
+**Free tier gating:** if `profile.tier === 'free'` → relational table hidden with upgrade CTA instead. Use `usePlatform()` + profile tier check.
+
+**Done signal:** `/settings` → Memory tab renders all three sections, edits/deletes round-trip to backend.
+
+---
+
+### TASK 4.4: i18n keys
+
+Add translation keys to all 5 JSON files under namespace `settings.memory.*`:
+- `corePreferences`, `peopleRelationships`, `dangerZone`, `forgetEverything`, `forgetConfirm`, `addEntry`, `noEntries`, `upgradeToSeePeople`.
+
+Keep `common.*` reuse for `save`/`cancel`/`delete`/`edit` (already present).
+
+**Done signal:** All 5 locale files include the new keys.
+
+---
+
+### TASK 4.5: Phase 4 checks
+
+- `cd adiuvAI && npx eslint . --fix`
+- `cd adiuvAI && npx tsc --noEmit`
+- Manual: run `npm run start`, log in, open Settings > Memory, edit a core key, verify persisted via `GET /auth/me` memory echo.
+
+---
+
+## PHASE 5 — Proactive mining (Power tier only)
+
+### TASK 5.1: Scheduler skeleton
+
+**File:** `api/app/core/memory_maintenance.py`
+
+Two entrypoints, callable from a cron runner (APScheduler already a dep — if not, add):
+- `drain_extraction_queue()` — processes `extraction_queue` rows (Phase 2.4) for Free tier users, batched.
+- `mine_proactive_patterns(user_id)` — for Power tier users only. Reads last 30 days episodic, runs a single `gpt-4o-mini` call: "Identify recurring temporal/behavioral patterns". Writes results to `memory_proactive` with `confidence`. Applies decay (conf *= 0.9 per 7 days since last sighting).
+
+Register jobs in `app/main.py` startup (only if `settings.SCHEDULER_ENABLED=True`, default True; false in tests).
+
+**Done signal:** `pytest -q` green (scheduler disabled). Manual: setting `SCHEDULER_ENABLED=True` + dev run logs "memory cron tick" every 1h.
+
+---
+
+### TASK 5.2: Surfacing proactive hints
+
+**File:** `api/app/core/deep_agent.py` + `adiuvAI/src/renderer/components/home/DailyBrief.tsx` (if exists)
+
+Backend already injects `proactive_hints` into prompt (middleware). Confirm still works after changes; add unit test with seeded proactive row → assert string present in final system prompt.
+
+On renderer, if daily brief component exists, show proactive hints as chips under "I noticed…" header. If not, skip — not a regression.
+
+**Done signal:** System prompt includes proactive line when row exists + confidence ≥ threshold.
+
+---
+
+### TASK 5.3: Tier gate
+
+Add `TierFeature.PROACTIVE_MINING` to tier_manager — Power + Team only.
+
+**Done signal:** Free/Pro user → no cron row for them; Power user → mining runs.
+
+---
+
+### TASK 5.4: Phase 5 checks
+
+- `cd api && ruff check . --fix`
+- `cd api && pytest -q`
+
+---
+
+## PHASE 6 — Completion
+
+### TASK 6.1: Verify all files exist / modified
+
+New files:
+- [ ] `api/alembic/versions/*_associative_pgvector.py`
+- [ ] `api/alembic/versions/*_memory_relations.py`
+- [ ] `api/app/core/embeddings.py`
+- [ ] `api/app/core/memory_extraction.py`
+- [ ] `api/app/core/memory_maintenance.py`
+- [ ] `api/app/api/routes/memory.py` (or new routes appended in `auth.py`)
+- [ ] `adiuvAI/src/renderer/components/settings/MemorySection.tsx`
+
+Modified files:

+### TASK 6.2: Full gauntlet
+
+Run all four commands, expect exit 0:
+```bash
+cd api && ruff check . --fix
+cd api && pytest -q
+cd adiuvAI && npx eslint . --fix
+cd adiuvAI && npx tsc --noEmit
+```
+
+### TASK 6.3: Output completion promise
+
+If gauntlet green and file checklist complete:
+
+```
+<promise>MEMORY EVOLUTION COMPLETE</promise>

+## DO NOT
+
+- Skip the per-iteration caveman preamble — it is part of the contract of this loop.
+- Break zero-trust: never log / return plaintext user content in error paths. Relation `subject_label`/`object_label` ARE treated as identifiers — log OK. `notes_encrypted` never logged.
+- Introduce A-Mem-style retroactive memory rewrites. Explicitly out of scope (strategy doc §3.3).
+- Introduce AutoGPT-style reflective loops. Out of scope.
+- Store format prefs or device-specific UI data in core memory — that's electron-store territory (see PROMPT-onboarding.md for precedent).
+- Use Neo4j or any external graph DB — plain Postgres table is the spec.
+- Call OpenAI embeddings for Free-tier users.
+- Ship proactive mining (Phase 5) before Phase 3 (relational) is green — order matters.
+- Delete user rows in `forget-all` — only memory rows.
+- Let extraction pipeline or LLM normalization raise into the request path — always try/except, log, swallow.

+## CAVEMAN MODE REMINDER
+
+This document's plan is executed **under caveman:caveman ultra**. Every iteration: activate the skill first, then work. Terse prose in all user-facing text emitted during the loop. Code + commit messages + migration SQL stay normal per caveman plugin boundaries.
+
+If caveman plugin unavailable for any reason, STOP the iteration and report instead of proceeding in default mode — the loop contract requires it.
