A lesson as stored: the conscience’s Challenge plus provenance and consolidation state. Append-only: a merge writes a new version with the same id; readers keep the latest.

Fields

id: String

origin_ms: i64

repo: String

question: String

situations: Vec<String>

consequence: String

support: u32

episodes: Vec<String>

history: Vec<Value>

version: u32

engineers: Vec<String>

Engineers whose corrections this lesson was learned from, first contributor first.

joined: BTreeMap<String, i64>

When each later engineer joined (ms of their first episode merged in): trust.rs counts a lesson’s outcomes for an engineer only from then on. The first contributor is absent.

area: String

Kind of concern (trust.rs AREAS), set by the generalising model call; “other” if absent.

supersedes: Vec<String>

Existing lessons this one replaces or contradicts; the conscience asks this one instead.

source: String

“queen” for a queen answer (queen.rs), “import” for team knowledge read from a directory (assimilate_dir.rs), kept across merges; empty for learned lessons.

scope: Vec<String>

Where the lesson applies, as names (systems, repos, services: “Orion”, “harbor_orion”). Empty: wherever it matches. A scoped lesson is asked only when the drone’s context names one of them (conscience.rs in_scope), so a team rule for one system never reaches another.

overrides: String

The outside rule or idiom this lesson replaces, and why (“upstream petri-net-design seeds a budget with a reset arc; Orion drains instead because …”). Lessons replace lessons via supersedes; this names what is not a lesson (a vendored skill, upstream docs). Rendered with the question: an override that does not name what it replaces loses to it (seen in an earlier eval).

origin: String

Source location of an imported lesson (path:line in the source repo); empty for learned ones.

facets: Vec<String>

Alternative phrasings of the lesson for search (facets.rs): the concept without names, the symptom, the action, the consequence, German, the identifiers as aliases. Each is its own BM25 document (conscience.rs rank); never shown to a drone. Empty for lessons learned before facets existed.

reach: String

Who should hear the lesson (reach.rs): empty for the team, repo for its repo only, personal for a tombstone withdrawn to an engineer’s private collective.
