Solution

The fractal unit of completed work

Definition

Mechanism

A recursive Work unit that contains an output Artifact, provenance identifying its creator and creation time, and a reference to its originating Task. Composite solutions also record a component Tree of the sub-solutions used to generate them; omission of that tree denotes a leaf. It is the verifiable output container validated against the task's acceptance criteria.

Preconditions

  1. Artifact generated
  2. Task ID is valid

Postconditions

  1. Solution sealed and ready for transport

Invariants

  1. Immutability: Once finalized, Artifact and Provenance cannot be modified.
  2. Provenance attributes the Solution to its Creator and the time of creation.
  3. Where the Creator is untrusted, attribution is cryptographically signed.

Risks

Failure modes

  1. Orphaned {{artifact}}

    Solution does not reference a valid Task ID.

  2. Broken Lineage

    a composite Solution references a sub-solution whose verification fails (Chain of custody broken).

  3. Schema Violation

    Artifact data does not match acceptance criteria type.
