Enum SessionSource

Which tool produced a session log.

This is read-provenance: a fact recovered when a log is loaded (stored in SessionMeta::source, filled in by auto-detection in detect_source), describing which tool originally wrote the file on disk. It answers “where did this session come from?” — e.g. for inspect/convert display in the CLI.

It is deliberately distinct from SessionFormat, even though the two enums’ variant lists currently coincide: SessionFormat selects a serialization codec (what to parse/export as), while SessionSource records history (what wrote the file). The pair is intentionally kept separate rather than merged — a session loaded from one tool’s log can still be exported in the other tool’s format, and the two concepts could diverge further (e.g. a format that is readable but not attributable, or multiple versioned formats sharing one source).

Variants

ClaudeCode

A ~/.claude/projects/.../<id>.jsonl transcript.

Codex

A ~/.codex/sessions/.../rollout-*.jsonl file.

OpenCode

An OpenCode session — multi-file JSON tree(s) or SQLite opencode*.db (docs/interop/opencode-pi-spec.md §1.2). Detection and loading are wave B; this variant exists now so SessionSource/SessionFormat stay 1:1 per the frozen interop spec (§0).

Pi

A ~/.pi/agent/sessions/--<enc-cwd>--/<iso>_<sessionId>.jsonl transcript (docs/interop/opencode-pi-spec.md §1.1) — line-oriented JSONL like Claude Code/Codex, so it shares their byte-lossless native round-trip property.

Grok

A Grok session transcript stored as ~/.grok/sessions/<percent-encoded-cwd>/<session-id>/chat_history.jsonl.

Gemini

A Gemini CLI transcript stored under ~/.gemini/tmp/<project>/chats/session-*.jsonl.

Goose

A Goose session exported through _goose/unstable/session/export, or reconstructed from Goose’s sessions/sessions.db native store.

Native

P5-3 safety-hardening fix (Fable-5 review, LOW “translation-fidelity cosmetic”): a session that was never imported from ANY foreign tool’s log at all — authored directly by supercode’s own agent loop, with no foreign-tool prefix (Session.raw starts empty). Currently only crate::agent::Agent’s persist_subagent_transcript (P5-3, natively-spawned spawn_subagent children) uses this — before this variant existed, that call site built its blank Session via Session::from_claude_code_str("") purely as an “empty parser to get a blank skeleton” trick, which left meta.source == SessionSource::ClaudeCode even though nothing Claude-Code-shaped was ever involved, mislabeling a native supercode spawn as an imported CC session on disk (and in any inspect/convert reading it back). Never produced by auto-detection (detect_source) or any from_<tool>_str loader — only by code that explicitly constructs a SessionMeta with this source, so no existing imported-session path can ever observe this variant appearing where it didn’t before.
