- Add getBlastRadius(): never-throwing orchestration that fans out to
searchDeliveredMessages + getHeldMessages + getThreatEvents (D-01,
unconditional fan-out) and merges into normalized matched/delivered/
held/rejected/clicked counts + perRecipient status array
- Config gate (BLAST-02): returns status:'unavailable' reason:'not_configured'
synchronously when Mimecast is unconfigured, never constructs the client
- Redis-backed 5-min cache (D-04) via redis-client.ts, short-circuits before
any MimecastClient call on hit
- clicked derived best-effort from getThreatEvents() analysis[] (D-02);
documents the /api/ttp/url/get-logs limitation in code
- Documents D-05 known limitation: single global getMimecastClient() only,
not per-company mimecast_tenants
- Unrecognized delivered-message status strings treated conservatively as
non-rejected (A3 unconfirmed enum), raw values logged at debug level
- Add lib/services/mimecast-blast-radius.test.ts covering config gate,
cache-hit short-circuit, fan-out merge, never-throw-on-error, and
unknown-recipient classification
- Log pre-existing unrelated itglue-search.test.ts failures to
deferred-items.md (out of scope for this plan)
