A verification harness around your AI agent. So memory compounds instead of corrupts.

Microsoft DELEGATE-52 (arxiv.org/abs/2604.15597, April 2026) measured what most operators already feel: frontier LLMs corrupt 25% of professional content over 20 edit interactions. Document size amplifies the failure 5×. The paper concludes the only reliable mitigation is a domain-specific verification harness around the model.

This is one.

Four moving parts.

Vault as ground truth. Markdown on disk. Decisions, patterns, context. The model reads from the vault, not from chat history.
Hooks as deterministic guards. Pre-write hooks block bad edits before they land. Em dashes in external prose. Frontmatter without required fields. Calendar events without timezone offsets. Raw git add -A on a 60K-file vault.
Bi-temporal rule lineage. Every codified rule carries two clocks: when it was written, and when it was last verified. The resolver detects conflicts. Drift detection scans high-edit files weekly for cumulative semantic shift. The closed loop promotes hardened patterns into procedural memory and demotes stale ones.
Session lifecycle. Each session start loads context. Each session end cascades decisions, insights, and to-dos to the right files. Nothing stays trapped in a chat transcript.

Free to install. Free to run. Your Claude subscription is the inference. No vector database, no fine-tune, no per-seat license.

The repo is shaped by an active vault: 10,000 markdown files, twelve years of journals, two writing projects, a startup to raise for, an AI consulting practice. The system was forced into shape by the work, not designed in a lab. It's used by the founder who built it; new installs land each week through the consulting practice.

If you carry context professionally (investor relationships, board decisions, team dynamics, contractor handoffs) plus the parts of a life that don't fit inside the company, this is for you.

A Monday after the system is installed

7:04 AM. You run /journal. The advisory panel (Naval, Brene Brown, Hormozi, Buffett, plus the custom voices you build) meets your draft and pushes back where your thinking is soft. You walk into the day with ten-minute clarity on something that would have taken an hour of spinning.

11:20 AM. A one-hour meeting ends. You drop the transcript in. The system files it, tags participants, extracts five action items, routes each one to the right owner by role, and drafts the follow-up message for you to review. Thirty-five minutes of post-meeting work compressed to two.

1:00 PM. Thirty minutes between blocks. You open the book draft. Claude reads the new scene against every previous chapter in the vault, flags a continuity break in chapter three, and scores the voice match against your own corpus. You fix the weak sentence in two minutes and close the tab.

3:00 PM. You write a one-liner for a contractor. A hook blocks the save: missing the four required fields (source, location, shape, channel). You rewrite the task in ninety seconds. She ships in one pass. You save a $500 week.

6:45 PM. A close friend texts about something the two of you talked through six months ago. You ask Claude. Three seconds later you have the thread, the date, what was unresolved, and what you promised. You reply from context, not from guesswork.

Sunday, 9:00 PM. The weekly ritual runs. Every open loop from the last fourteen days surfaces in a single view, across the whole life: the company, the book, the consulting, the people you care about. Decisions pending, promises outstanding, follow-ups due. You resolve three, deliberately defer two, and close the week with a clean runway into the next one.

Monday starts with context, not amnesia.

When your team joins

The personal version of this system already runs your half: your context, your decisions, your patterns. The leverage step is wiring your team into the same brain without giving them access to your personal vault.

Here is what that looks like:

Your personal vault contains everything: business, team, family, projects, writing, journals.
Inside it, a team folder syncs bidirectionally with a separate team vault that your co-founders, operators, or contractors share.
They get the team vault. You get the integrated view across all of it.
Your business decisions can pull insight from your personal patterns. Your team folder routes work to specific people by role. Your to-dos shuffle between personal and team without ever leaking either way.
On top of that, a marketplace of skills and MCP servers custom-built for your team's exact workflows, optimized to your stack, your voice, your decision logic.

The personal version of the repo handles your half. The team version handles theirs, plus the sync, plus the per-team customization.
