One-time renormalization pass under the .gitattributes added in the
previous commit. Every tracked text file now uses LF. No semantic
changes — verified via git diff --cached --ignore-all-space showing
zero real differences. Future diffs will only show real content
changes.
This commit will appear huge in git log --stat but represents zero
behavior change. Use git log --follow --ignore-all-space or
git blame -w when archaeologically tracing through this commit.
Adds inline pipeline stages between the bus and the severity router:
- Inhibitor: suppresses lower-or-equal severity events when a key
in event.inhibit_keys is already active. TTL configurable, default
30 minutes.
- Grouper: coalesces events sharing group_key within a time window
(default 60s). Most recent event wins. tick() and flush_all()
drive emission; no background timers in Phase 2.2.
- build_pipeline now wires: bus -> inhibitor -> grouper -> severity_router
Phase 2.1 dispatcher tests continue to pass unchanged.
