# 2026-05-08 — Icarus V2 Rebuild Day

## Key Decision: The Map
After a comprehensive architecture grill, Matt and I aligned on:

**The Vision:** Icarus as a **standalone sovereign appliance** — an M4 Mac Mini running a bespoke daemon, no OpenClaw dependency, no Cloudflare, no cloud model for core loop. Three capabilities: inbox→calendar, ambient coordination (Telegram shadow), knowledge retrieval (ChromaDB RAG).

**Three Director Verdicts:**
1. **Access** → Tailscale Funnel (not Cloudflare/domain). Dashboard = admin console, Telegram = product UI.
2. **Infrastructure** → Bespoke daemon (not OpenClaw). APScheduler + direct Telegram API calls. Kill the 8 OpenClaw cron dependencies.
3. **Config** → Template YAML (not hard-coded). Ship `template.yaml`, Hoffmann profile lives in `hoffmann.yaml`, engine reads dynamically.

**Archived legacy Icarus (22K lines, 84 files)** → `~/archive/icarus-legacy-20260508/`
**Created new Icarus V2 at** `~/icarus/` — 1,478 lines, 8 modules.

## Built Today
- `icarus/config/loader.py` — YAML-based family config loader with inference rules
- `icarus/tripwire.py` — V2.1 regex tripwire, 21-test validation, 0.35 threshold
- `icarus/extractor.py` — Local LLM extraction (Ollama, adaptive model selection)
- `icarus/event_graph.py` — Canonical family state store (SQLite, events + extractions tables)
- `icarus/brain/__init__.py` — ChromaDB knowledge retrieval (single source of truth)
- `icarus/daemon.py` — Bespoke daemon with IMAP poller, Telegram long-poll, internal scheduler
- `icarus/config/families/template.yaml` — Template for new families
- `setup.py` + `pyproject.toml` — Package structure

**Gaming PC stays wired in** as M4 facsimile. If architecture hits a wall because dev != target, pivot noted.

```

## Remaining Work (in priority order)
1. Wire the HoffDesk IMAP proxy callback to new Icarus modules (replace dead `_on_email_received`)
2. Create optional FastAPI mounts in HoffDesk for Icarus dashboard endpoints
3. Migrate the 8 OpenClaw cron jobs to daemon's APScheduler
5. Test end-to-end: email → IMAP → tripwire → extraction → event graph
6. Write `install.sh` for the appliance one-command install

## Tripwire Calibration (v2.1)
- 21 test messages: 16 positive + 5 negative
- Fire threshold: 0.35 (down from 0.4 v2)
- Name mention boost: +0.08 when family member name + other signal
- Key fix: `name_mention` pattern needed `re.IGNORECASE`, `hour_only` pattern added for bare hour references
- All 21 pass

## Cron Separation (afternoon session)

**Shadow TTL Purge** and **Thoth Shadow Ingest** — dropped from scope. TTL purge was born of old data paranoia (ChromaDB is Icarus-native now, no shared infra concerns). Thoth is a candidate for the experiments workspace, not a cron.

### Midas & Daedalus Crons — Migrated to system crontab
**Decision:** Market AM/PM briefs (Midas) and Bluesky crosspost (Daedalus) belong to their respective workflows, not OpenClaw's cron system. System crontab is more reliable for simple Python script execution (no 5-minute agent timeout, no DNS dependency on ollama.com).

**Changes made:**
- Disabled 3 OpenClaw crons: `market:am-brief`, `market:pm-brief`, `blog:bluesky-crosspost`
- Added system crontab entries with correct script paths
- Fixed bug: AM brief was calling `daily_briefing.py --am` (flag not supported); now calls `premarket_briefing.py`
- PM brief DNS error (ollama.com resolution failure) was a transient issue, not code

### Experiments Directory
Created `~/icarus/experiments/` for shadow-mode parallel testing:
- `README.md` — rules and how-to
- `thoth/adapter.py` — Thoth extractor shell, same interface as production
- `llm-swaps/README.md` — LLM comparison testing guide
- Wired into daemon via env vars: `ICARUS_EXPERIMENT`, `ICARUS_EXPERIMENT_NAME`, `ICARUS_EXPERIMENT_LOG`, `ICARUS_EXPERIMENT_PROMOTE`
- Experiment runs alongside production, logs comparisons to `experiments/<name>/eval_results/`
- Auto-promote defaults to **off**
