COMBDLC FOR BUZZ*

*Independent. Open source. The good kind of unofficial.

Independent open-source DLC for Buzz

Your workspace is buzzing. Keep what it learns.

Comb gives Buzz a permission-aware path from signed channel conversations to ratified project memory—with receipts for every claim. Huddles, branches, workflows, and broader company intelligence are the roadmap.

The idea / 01

Buzz captures the work. Comb keeps the meaning.

Buzz already gives people and agents one shared, signed history. Comb turns that history into living project memory: decisions, disagreements, storylines, gaps, owners, and next moves—each connected to the events that made it true.

The proof / 02

Ask why. Get the whole why.

A decision is only useful if you can inspect its evidence, dissent, blind spots, and what changed afterward.

The mechanism / 03

From room noise to organizational memory.

Comb does not declare truth from a summary. It proposes an understanding, shows its sources and blind spots, and lets people decide what becomes part of the project’s memory.

  1. 01Talk
  2. 02Find the claims
  3. 03Check the evidence
  4. 04Ratify
  5. 05Remember
  6. 06Act
01

Receipts, not vibes.

Every claim opens to the exact event, transcript span, workflow run, patch, or artifact that supports it.

02

Truth has a timestamp.

Ask what the project believes now—or what the team knew when a decision was made.

03

Memory respects the room.

The compatibility proof keeps evidence channel-local and invalidates dependent memory after source deletion. Broader permission-loss propagation is next.

04

The company can see itself.

The larger vision is to surface living storylines, disagreements, communication gaps, stalled commitments, and the next moves worth making.

The company can see itself / 04

It notices who missed the memo.

Comb connects the ratified decision to the work still moving on old information, then asks before it acts.

Communication gapIllustrative data
17h

Design is planning against the July 31 launch. Engineering ratified August 7.

  • Current design plan references the superseded July 31 decision.
  • No member of Design viewed or reacted to the ratification thread.
  • Design’s next scheduled milestone depends on the old date.
Proposed action

Post the ratified decision and changed dependencies to #design-atlas.

Requires human approval

Built for Buzz / 05

Native to the room. Not another tab.

Comb is being built to read Buzz’s signed event stream, follow Buzz identities and room membership, and return proposed knowledge where people and agents can inspect, challenge, ratify, and use it.

Scoped compatibility proof passed against Buzz main at acfbb1b on July 22, 2026. This validates the demo contract. It does not mean these semantics are upstreamed into Buzz.

Ship the destination. Upstream the primitives.

Comb is being developed independently against Buzz’s public repository. Nothing on this page is part of Buzz until Block’s maintainers review and merge it.

Status language is rendered from the project’s source-of-truth manifest. The scoped demo is tested. The event semantics are not upstreamed. “RFC open” is not “PR open.”

Comb came from a bigger question.

What if the whole workplace remembered?

Comb was developed while building STRIDE—an open operating system for how humans and agents talk, decide, make, and remember together. Comb brings that intelligence architecture to Buzz.
