Lightcone Ledger

01 / The problem

What had to change

Flight release depends on aircraft, crew, route, authority, procedures, and current conditions. Separate tools make the reason behind a decision hard to preserve.

02 / The constraints

What the system had to respect

• The same records and rules must produce the same checks.
• A person must keep authority over the release decision.
• The evidence must remain reviewable after the flight.

03 / The build

What I made

• A connected record for planning, release, flight, review, and proof.
• Deterministic checks that cite the applicable rule or procedure.
• Change history, human approvals, and scoped evidence access.
