Linear / Jira / Plane class
Project management stack
Strengths
- - Backlog structure
- - Workflow controls
Limits
- - Weak signal capture
- - No native outcome verification
Resource comparison
Project tools, calendar tools, meeting recorders, knowledge workspaces, and engineering copilots each solve a slice. ContractSpec starts by governing the handoff between them, then expands only after the first lane is stable.
Current shipped scope: Meeting-to-Execution, certified bridges, reviewed drafts, guarded handoff, checks, and trust controls across web, API, and MCP.

|---|
ContractSpec starts narrow on purpose. The bigger replacement thesis is credible only because the first lane is governed.
Shipping
Start with Meeting-to-Execution, certified bridges, reviewed drafts, guarded handoff, and scheduled checks.
Next
Add adjacent inputs, handoffs, companion surfaces, and exports only after the first reviewed lane is stable and legible.
Trust
Broader automation stays bounded by review queues, approvals, lineage, rollback, audit trail, and policy checkpoints.
Vision
The broader operations OS remains future-facing. The public product claim expands only after the current lane is proven.
