Every BreadEvent now gets a unique id at construction (via
BreadEvent::new/with_timestamp, and the normalizer's struct-literal call
sites, which all now assign one explicitly). A new caused_by field is
populated only when a Lua bread.emit() call runs synchronously inside a
bread.on subscriber's handler: LuaEngine tracks the currently-dispatching
event's id (set/restored around each handle_event invocation, single-
threaded so a plain Mutex-guarded slot suffices) and bread.emit()'s Rust
binding reads it when constructing the outgoing event. This lets chains of
Lua modules that react to each other's events be reconstructed instead of
timestamp-guessed from a live `bread events` log.
Also:
- bread events --tree renders the caused_by chain as an indented,
live-streaming-friendly tree instead of a flat line-per-event stream.
- API_VERSION bumped 1.4.0 -> 1.5.0 (additive-only change).
- Documentation.md's event envelope, bread.emit, and debugging-tips
sections updated with Since: v1.5 markers.
- New end-to-end regression test spawning the real daemon with 3 chained
Lua handlers (A emits X on trigger, B emits Y on X, C emits Z on Y) and
asserting caused_by threads correctly through all three hops.
Security:
- Remove `bread modules install github:…`. Remote fetch pulled unreviewed
third-party Lua and ran it with full bread.exec() privileges in an
unsandboxed runtime. Module install is now local-only; parse_source
rejects github:/git: with an explicit message.
bread-sync extracted from the workspace (parked for its own project):
- Removed from workspace members (now excluded); see bread-sync/EXTRACTION.md
- Removed the entire `bread sync` CLI surface and now-unused deps
(bread-sync, reqwest, tar, flate2; tempfile demoted to dev-dependency)
- Removed the sync.status IPC method from breadd plus its integration tests
- Moved the generic `expand_path` helper into bread-shared (with unit tests)
CI now actually runs and gates quality:
- Trigger on master/dev (was `main` — CI had never run, not once)
- Added `cargo fmt --check` and `clippy -D warnings`; fixed 4 clippy warnings
- Dropped the macOS matrix entry (breadd is Linux-only: udev/rtnetlink);
added the libudev-dev system dependency the Linux build needs
Hardening / honesty:
- New ipc test: daemon survives repeated reloads and the event pipeline
resumes (the prior suite only had a single happy-path reload check)
- Docs scrubbed of sync across README/Documentation/Overview/DAEMON
- "production-ready" and "compositor-agnostic" claims reworded to match
reality rather than aspiration
Note: bread-sync/src/export.rs held pre-existing local WIP authored outside
this change set and is intentionally excluded from this commit.
