Update Knowhow
Use the archival contract with an existing knowhow destination. This alias can complete the task directly; it does not depend on being able to invoke another skill.
Preserve exact observed commands/configuration, relevant versions, provenance and verification. Separate symptoms, candidate causes, attempted fixes and verified resolution. An unresolved investigation may be saved as unresolved; a failed command does not prove a fix or justify changing the environment.
Update an existing entry when it covers the same problem. Carry forward the task's archival authorization, check the changed slice, and report paths and remaining uncertainty. Do not duplicate the record into a personal wiki or commit/publish it unless that destination/action was also requested.
