Crafts
A craft is the fundamental unit of work in ATC. Each craft represents a single discrete change to the codebase, tied one-to-one with a git branch.
Aviation Analogy
In aviation, an aircraft carries cargo from one airport to another along a planned route. In ATC, a craft carries a code change from creation to merge, following a flight plan of ordered milestones.
Properties
| Property | Type | Description |
|---|---|---|
| Callsign | string | Unique, immutable identifier for the craft |
| Branch | string | The git branch associated with this craft (1:1) |
| Cargo | string | Description of the change and its scope |
| Category | CraftCategory | Type of change — determines pilot eligibility |
| Captain | Pilot | The pilot-in-command; exactly one per craft |
| First Officers | Pilot[] | Zero or more certified co-pilots |
| Jumpseaters | Pilot[] | Zero or more observers (no code modification) |
| Flight Plan | Vector[] | Ordered sequence of milestones to complete |
| Black Box | BlackBoxEntry[] | Append-only event log |
| Controls | ControlState | Who can currently modify code |
| Status | CraftStatus | Current lifecycle state |
Rules
- RULE-CRAFT-1: Every craft must have a unique callsign that never changes after creation.
- RULE-CRAFT-2: Every craft is associated with exactly one git branch. One branch, one craft.
- RULE-CRAFT-3: Every craft must have a cargo description assigned at creation — you can't fly without knowing what you're carrying.
- RULE-CRAFT-4: Every craft must have a category assigned at creation, which determines which pilots are certified to fly it.
- RULE-CRAFT-5: Every craft must have exactly one captain at all times. No craft flies without a pilot-in-command.
Example
Craft:
Callsign: fix-rate-limiter
Branch: fix/rate-limiter-bypass
Cargo: "Fix rate limiter bypass when X-Forwarded-For header contains multiple IPs"
Category: Backend Engineering
Captain: agent-bravo
First Officers: [agent-charlie]
Jumpseaters: [agent-delta]
Status: InFlight
