Module error 

Error types for lazy DataContext sources.

Each source’s real error variants land with its owning epic (e.g. UsageError is real under the lsm-y6m epic; GitError lands with lsm-8jl). Sources still in stub form return the NotImplemented variant so the plugin runtime can expose a uniform error surface to scripts.

NotImplemented is temporary. When an epic lands real variants for a given error enum, the NotImplemented variant is removed in the same commit. Because each enum is #[non_exhaustive], adding new variants is non-breaking; removing NotImplemented is a breaking change for any external code that matches on it. v0.1 treats that window as acceptable — no external consumers exist yet, and the stub’s whole purpose is to signal “not wired up.”

Enums

ClaudeJsonError

Errors from reading ~/.claude.json.

GitError

Errors from gix repo inspection. CorruptRepo covers gix::open failures; WalkFailed covers HEAD / revwalk failures once the repo is open. Inner causes are stringified at the construction boundary so the enum stays Clone + PartialEq + Eq — the Arc<Result<...>> memoization boundary requires it. See docs/specs/git-segments.md §Change log (v0.1.1) for the full rationale.

SessionError

Errors from the live sessions directory.

SettingsError

Errors from reading ~/.claude/settings.json + overlays.

UsageError

Errors from the OAuth /api/oauth/usage endpoint plus the cache stack, credential, and JSONL-fallback layers that feed it. Rendered to the user via the segment error table in docs/specs/rate-limit-segments.md.
