Add format_event_type() and calculate_duration() helpers to convert
raw timeline events into human-readable tables and metrics. RCA now
includes an Incident Timeline section and Incident Metrics (event
count, duration, time-to-root-cause). Postmortem replaces placeholder
timeline rows with real events, calculates impact duration, and
auto-populates What Went Well from evidence.
10 new Rust tests covering timeline rendering, duration calculation,
and event type formatting.
- Add migration 017_create_timeline_events with indexes
- Update TimelineEvent struct with issue_id, metadata, UTC string timestamps
- Add TimelineEvent::new() constructor with UUIDv7
- Add timeline_events field to IssueDetail
- Rewrite add_timeline_event to write to new table + audit_log (dual-write)
- Add get_timeline_events command for ordered retrieval
- Update get_issue to load timeline_events
- Update delete_issue to clean up timeline_events
- Register get_timeline_events in generate_handler
- Add migration tests for table, indexes, and cascade delete
- Fix flaky derive_aes_key test (env var race condition in parallel tests)
Rename custom API format handling from custom_rest to custom_rest with backward compatibility, add guided model selection with custom entry in provider settings, and rebrand app naming to Troubleshooting and RCA Assistant across UI, metadata, and docs.
Made-with: Cursor
Apply canonical rustfmt formatting in files touched by the clippy format-args cleanup so cargo fmt --check passes consistently in CI.
Made-with: Cursor
Inline format arguments across Rust modules to satisfy clippy -D warnings, and configure Cargo to prefer system OpenSSL so clippy builds do not fail on missing vendored Perl modules.
