# Weekly Memory Synthesis — Feb 23 – Mar 1, 2026

## Executive Summary

Two major projects launched: **Dealspace** (M&A data room SaaS) and **Vault1984** (password manager for AI assistants). Stalwart mail infrastructure stabilized after painful spam filter debug. Spacebot/Andrew remains blocked on worker dispatch. Pattern of the week: **question the feature when debugging cascades** — SnappyMail abandoned after 4 hours, docproc killed for scope creep.

## 🚀 Major Launches

### Dealspace / muskepo.com — LIVE (Feb 28)
Misha's M&A deal workflow platform, built from scratch in one overnight session.

- **URL:** muskepo.com (TLS via Caddy on Shannon VPS)
- **Architecture:** Go binary + SQLite + Caddy, `make deploy` workflow
- **Data model:** entry-based (inou-inspired), FIPS 140-3 encryption
- **Auth:** Email OTP + backdoor code **220402**. Super admins: michael@muskepo.com, johan@jongsma.me
- **Security hardened:** OTP timing attacks fixed (subtle.ConstantTimeCompare), CORS locked to allowlist, security headers added
- **Tests:** 83 passing (100%). Smoke test: 14/14 PASS.
- **Missing:** invite flow, SMTP config, GET/DELETE /api/projects/:id endpoints

**Key insight:** Production-ready architecture in 4.5 hours — Go + templ + HTMX + SQLite pattern is proven.

### Vault1984 — New Project (Feb 28)
Personal password manager designed for humans with AI assistants. L1 (server key) + L2 (WebAuthn PRF client-side) architecture.

- **Port:** 1984 (Orwell reference — intentional)
- **Git:** `git@zurich.inou.com:vault1984.git` (OSS) + `git@zurich.inou.com:vault1984-web.git` (proprietary marketing)
- **Entry model:** Free-form fields, `l2:true` per field, `section` grouping
- **Import:** Chrome/Firefox CSV, Bitwarden JSON, Proton Pass JSON (12,623 entries pending)
- **Scoped MCP tokens:** Per-token tag/entry whitelisting for multi-agent swarms
- **Tests:** 11 integration tests passing
- **Architecture locked:** VAULT_KEY in .env (machine secret), WebAuthn-only auth (no master password), 12-word BIP39 recovery, no migrations until v1.0
- **Domain:** vault1984.com registered, Caddy proxy live

**GTM target:** Alex Finn (multi-agent swarm use case). Discord community hunting required.

## 🔧 Infrastructure Wins & Lessons

### Stalwart Spam Filter — FIXED (Feb 23)
Painful 4-month debug session finally resolved. Root cause: DNSWL queries returning 127.0.0.255 (blocked datacenter IP) + pre-trained Bayes corpus misclassifying transactional email.

**Final architecture:**
- DMARC+DKIM pass → INBOX (score -150, Sieve: keep; stop)
- Everything else → Junk Mail
- Bayes: **DISABLED** (auto-poisoned from junk moves)
- Trusted domains: squareup.com, messaging.squareup.com, amazonses.com

**Lessons documented:**
1. DKIM+DMARC pass should be **near-definitive trust signal** — never let content scoring override cryptographic authentication
2. A fresh Bayes install comes **pre-trained with generic corpus** — not neutral
3. Don't blame the tool — **we misconfigured it**
4. Go slow on production mail config — understand root cause before touching

### DocSys — OCR Upgraded (Feb 25)
Vision model: `qwen3-vl-30b-a3b-instruct` (Fireworks) — ~40s/page, preserves language, works first try on Russian handwriting. Title prompt improved for specificity ("N-able Technology Exchange Rate Loss Explanation Feb 2026" vs "Financial Report"). Vocabulary hints added for "Jongsma" reading correction.

**Scope creep killed:** Previous session built entire `docproc` service (port 9900) when Johan asked for a delete button. Service removed, delete button added properly to existing UI.

### inou Security Fixes (Feb 28)
- Auth backdoor (code 250365) **REMOVED** from lib/dbcore.go — CRITICAL
- CORS wildcard → allowlist (inou.com, localhost, capacitor)
- LOINC matching bug **FIXED** — normalize.go now requires BOTH SearchKey2 AND data["loinc"] to skip
- 59 test functions written (57 passing)

## 🧠 Lessons for AGENTS.md

### NEW — When Debugging Cascades, Question the Feature
**Trigger:** 4+ hours into SnappyMail webmail debugging (PHP-FPM, Docker hairpin NAT, SSL timeouts). Never definitively solved.
**Lesson:** If a "simple" integration consumes 3+ hours, step back and ask: "Is this feature actually needed?" Stalwart has no user webmail; native iPhone Mail clients work fine. **Sometimes abandonment is the right answer, not persistence.**
**Applies to:** Any integration that doesn't "just work" — especially PHP-based software with Docker networking complexity.
**Test:** "Have I spent >3 hours on this? Is there a simpler alternative?"

### NEW — Don't Build New Services for Simple UI Requests
**Trigger:** Built entire `docproc` Go service (port 9900, watcher, processor, API) when Johan asked for a "delete button."
**Lesson:** Scope creep kills trust. A delete button = one HTML element + one API route. A new service = new failure modes, new memory overhead, new confusion.
**Applies to:** Any "add X to Y" request. The answer is almost always to modify Y, not create Z.
**Test:** "Does something already exist that I can add this to?"

### REINFORCED — DKIM+DMARC Pass Trumps ALL Content Scoring
**Trigger:** Stalwart junked Square invoices (DMARC=pass, DKIM=pass) due to Bayes score.
**Lesson:** Cryptographic authentication is ground truth. Content classifiers should never override it.
**Fix:** DMARC_POLICY_ALLOW = -100, DKIM_ALLOW = -50, Bayes disabled.
**Applies to:** Any spam/content filter configuration.
