Keep hard-won project reasoning discoverable.
engineering knowledge
Captures non-obvious reasoning from one verified solved problem as a validated, discoverable repository learning.
When to use it
Use when verified work produced non-obvious reasoning that the final implementation and existing documentation do not preserve.
Give it a project containing verified solved work; by default it works interactively and writes or updates one durable learning when the work qualifies.
