Follow one fact.

One email, start to finish: how Team0 checks it, keeps it true, and hands it to every agent you use, only where you allow.

Every AI agent you use only knows what you’ve told it.

Not your work, your people, or the meeting that moved an hour ago. Team0 gives every agent one shared understanding. To see how it works, follow Jordan’s email from the moment it lands to the moment an agent answers with it.

Email from Jordan

“Can we move the pilot review to Thursday?”

Tue 09:12 · this is only the ask

Your calendar

Fri 11:00 Thu 14:00

Tue 09:40 · Pilot review moved

Two signals about one meeting. The difference between them matters later.

Every input becomes a background job.

It lands in a queue, deduplicated, so nothing is processed twice. Six queues by urgency, worked on both servers.

Questions save nothing
A question is never a fact.
Agents’ reports are kept as heard
Until something confirms them.
Agent and API input is encrypted
And deduplicated on the way in.
Agent words erased at 7 days
What was learned from them stays.

Every claim is checked before it becomes a fact.

Who said it, about whom, and when. One writer turns claims into facts, so two jobs never race to save different versions of the truth.

  1. 1Extract: Typed claims plus the exact source line
  2. 2Resolve identity: The same person from any source
  3. 3Enrich records: Names, companies, logos
  4. 4People vs senders: A person, or an automated sender
  5. 5Link names: Only when certain
  6. 6Shape: Kind, about whom, when
  7. 7Write: Trust lane, provenance, history

Heard is not confirmed

Pilot review: Thursday 14:00

confirmed

Your calendar moved the meeting at Tue 09:40. That is the record, so the fact is confirmed. Jordan’s email stays attached as the reason it moved.

Inside every fact.

A fact is more than a sentence. It keeps where it came from, how far to trust it, and every value it ever had. Nothing is silently overwritten.

Three clocks on every fact

When it was said, when Team0 learned it, and the date it’s about. Drag through the week to see what Team0 knows at each moment.

Example: Jordan's email arrives Tue 09:12. Until Tue 09:41 the record is still Friday 11:00, and Jordan's ask is kept as heard. The calendar move was said at Tue 09:40 and learned at Tue 09:41; from then the fact is Thursday 14:00, confirmed, with Friday 11:00 kept in history. The date it is about is Thu 14:00.

What Team0 knows at Tue 10:00
Pilot review: Thursday 14:00Fri 11:00
confirmedThe calendar moved it. Friday is kept in history, not erased.

Twelve checks, on every save and every night.

A ring of truth checks keeps the understanding current. Thursday replaces Friday, and the history stays. Pick any check.

  • Stale heard items expire: Unconfirmed items fade out instead of hardening into facts.
  • Single values replaced: A newer value takes over. Thursday 14:00 replaces Friday 11:00.
  • Update check on save: Does this replace an older fact? Asked every time something is saved.
  • Plan changes: Judged right after saving, so a moved plan is never left in two places.
  • Contradictions caught: When two current values clash, Team0 notices.
  • Disagreements kept: Kept side by side, and your agent asks you which one holds.
  • Promises kept, settled: A promise is linked to whatever closed it.
  • Calendar moves settle asks: The calendar is the record. It settled Jordan’s ask.
  • Corrections propagate: Fix one fact and everything built on it updates.
  • Settlement fence: What is closed stays closed. Old echoes can’t reopen it.
  • Relationships, 2 vendors: A second model from a different vendor confirms each relationship.
  • Nightly truth check: Every night, facts are re-judged with full context.

Facts link into a picture, and it keeps itself current.

People, companies and moments link into storylines. Every night the whole picture is brought up to date, in every workspace.

Later, a different agent asks.

Codex never saw Jordan’s email or your calendar. It has never been told about the pilot review.

Codex asks Team0:

“When is the pilot review with Jordan?”

One read, shaped by the question.

Five kinds of request, one ranked read. Team0 works out what the question needs before it fetches anything, and says “no record” instead of guessing.

  • named
  • briefing
  • inbox
  • topic
  • continuation
  1. What it needs: Decides what to fetch
  2. Resolve names: Jordan is a known person, or the answer is “no record”
  3. Read plan: One question, one scope
  4. Scope: Owner, agent, or public; fails closed
  5. One ranked read: Words, typos, meaning, recency, importance
  6. Interpret: Current, settled, contested, or heard
Thu 14:00 · confirmed2 sourcespacket scoped to Codex

Every read and write passes one governed door.

Each agent sees only what you allow. Tap a step to see what it does.

  1. request: Codex asks a question.
  2. sign in: OAuth, or a key issued to that one agent.
  3. grant: The scope you gave this agent. It decides what Codex can see.
  4. limits: Deduplicated and rate limited.
  5. privacy: Agent input is encrypted on intake.
  6. receipt: What it asked and what it got, written down.
  7. packet: Only then does the answer leave, scoped to Codex.

Grant. The scope you gave this agent. It decides what Codex can see.

Codex

Codex gets “Thursday 14:00, confirmed.” What it learns can be saved back.

Stop saving, or stop all access, per agent, any time.

The answer carries its proof.

Not just a time. The agent can say where it came from, and that it was confirmed, not merely asked for.

Codex asks:

“When is the pilot review with Jordan?”

Team0

Team0 answers:

“Thursday at 14:00, confirmed by your calendar. Jordan asked for it by email.”

Every agent reads the same understanding.

And can write back to it. Each one sees only what you allow. Point at an agent to see how it connects.

Every turn

A plugin reads before each turn and saves after it.

MCP plus standing instructions. What they relay is kept as heard.

Codex reads Team0 before every turn and saves after it, so it starts each turn knowing the pilot review is Thursday.

What is kept, and for how long.

Raw words don’t stay. Learned facts stay, with their history; the raw words around them are erased by a daily job.

  • The read log’s content: 24 hours · its record stays 30 days
  • Agent conversation words: 7 days · what was learned stays

This is everything underneath.

The whole path on one page: sources, the write path, the World Model and its twelve checks, the read path, the governed door, and every agent.

  • One private schema per workspace.
