| 1 | //! `EventMsg`-out API in `crates/protocol` (issue #5261, Phase A1 of the |
| 2 | //! core/protocol extraction spec). |
| 3 | //! |
| 4 | //! Mirrors `crates/tui/src/core/events::Event` variant-by-variant as a |
| 5 | //! serializable protocol. The TUI's `rx_event` / `Event` channel, the |
| 6 | //! app-server's SSE stream, and the CLI's `stream-json` output all speak this |
| 7 | //! one type so headless and TUI observe byte-identical event shapes for the |
| 8 | //! same `Op`. |
| 9 | //! |
| 10 | //! Parity is compile-enforced from the engine side: |
| 11 | //! `crates/tui/src/core/protocol_parity.rs` matches every engine `Event` |
| 12 | //! variant exhaustively into an `EventMsg` (`protocol_covers_engine_events`). |
| 13 | //! Adding an engine variant without a twin here fails to compile. |
| 14 | //! |
| 15 | //! Payload fidelity rules for this phase: |
| 16 | //! |
| 17 | //! - Scalars, ids, lifecycle enums, route/billing receipts, tool outcomes, |
| 18 | //! MCP snapshots, approvals, and gate decisions are typed here. |
| 19 | //! - Deep domain payloads whose canonical serde type still lives above this |
| 20 | //! crate (goal snapshots, sub-agent results, coordination projections, |
| 21 | //! mailbox messages, transcript messages, tool catalogs, tool inspection |
| 22 | //! snapshots, workflow UI events) cross as `serde_json::Value` produced by |
| 23 | //! that type's own `Serialize`. They are typed in later phases; the variant |
| 24 | //! and its field names are already stable. |
| 25 | //! - Engine-only handles (`oneshot`/`Notify`, `Arc<HookExecutor>`) never |
| 26 | //! cross. A variant that carried one is projected without it. |
