# 2026-04-26 — Icarus Phase 5 Real World Sprint

**Session Duration:** ~12 hours continuous  
**Collaborators:** Matt (Director), Wadsworth 📋, Socrates 🧠, Daedalus 🎨  
**Status:** Phase 5 Week 1 In Progress

---

## 🎯 Major Deliveries

### Phase 5a: Data Abstraction (Socrates)

| Component | Status | Location |
|-----------|--------|----------|
| `hoffmann.yaml` | ✅ Complete | `icarus/config/families/hoffmann.yaml` |
| `family_loader.py` | ✅ Complete | `icarus/core/family_loader.py` |
| Briefing generator refactor | ✅ Complete | Uses YAML, not hardcoded |

**Decision:** Single-tenant modularity. Family context loaded from YAML, not hardcoded strings.

### Phase 5b: Memory System Port (Socrates — In Progress)

| Component | Status | Notes |
|-----------|--------|-------|
| Spec delivered | ✅ | `icarus-phase-5b-memory-port.md` (11,448 bytes) |
| `router.py` | 🔄 In Progress | Adapted from costco_route |
| `memory/engine.py` | 🔄 In Progress | ChromaDB learning |
| `validation/sanity.py` | 🔄 In Progress | Hallucination prevention |
| `memory/replay.py` | 🔄 In Progress | SQLite spooler integration |

**Constraint:** Copy, Decouple, Sever. Zero imports from costco_route. Icarus is sovereign.

### Phase 5c: System State View (Daedalus — Complete)

| Component | Status | Location |
|-----------|--------|----------|
| Handoff doc | ✅ | `SYSTEM-STATE-HANDOFF.md` |
| Template | ✅ | `system-state.html.j2` |
| Styles | ✅ | `system-state.css` |
| API endpoint | ⏳ Pending | Socrates to wire `/system/state` |

**Features:** Read-only dashboard, HTMX polling, confidence bars, recent decisions.

## 🔄 Costco Route Assessment

**Analyzed:** Router, memory engine, validation logic, recipe extraction  
**Decision:** Option A — Direct port, not shared library  
**Rationale:** Director veto on Premature Abstraction. Icarus must be sovereign.

**Port strategy:**
- `router.py` → family member routing (zones → members)
- `item_memory.py` → assignment learning (items → documents)
- `pipeline.py` validation → sanity checks

## 📚 Documentation Updated

| Document | Purpose |
|----------|---------|
| `icarus-phase-5-real-world-sprint.md` | Sprint plan, 3 components |
| `icarus-phase-5b-memory-port.md` | Port spec (Option A) |
| `SYSTEM-STATE-HANDOFF.md` | Daedalus → Socrates handoff |
| `hoffmann.yaml` | Family config (names, grades, inference rules) |

---

## 🎯 Success Criteria Tracking

| Criterion | Status |
|-----------|--------|
| YAML drives family inference | ✅ Complete |
| System State view shows rules + routing | 🔄 75% (template done, API pending) |
| Memory learning loop | 🔄 In Progress |
| Zero multi-tenant code | ✅ Enforced (single-tenant modularity) |
| SQLite spooler integration | 🔄 In Progress |

---

## 📅 Next Actions

1. **Socrates** completes memory port (router, engine, validation, replay)
2. **Socrates** wires `/system/state` API endpoint for Daedalus template
3. **Wadsworth** validates integration, zero cross-domain dependencies
4. **Matt** begins UAT on Week 1 Day 5 (tomorrow or next session)
