The file had drifted four indexes behind c2-server, so the 2026-08-23 deploy offered to delete four live indexes and then added ASC copies of two that already existed as DESC. Reconciled against gcloud's actual list. Adds the two backend indexes that were live but undeclared and are genuinely in use -- calls(status, ended_at) for recorrelation_sweep's ended-call scan and calls(system_id, ended_at) for vocabulary_learner. Deleting either would have broken a background loop with no frontend symptom. Declares every index ASCENDING. Firestore scans an index in either direction, so org_id+started_at ASC already serves the orderBy(started_at, 'desc') that every frontend hook actually asks for; a matched ASC/DESC pair is one index of pure write amplification on every call document. The three duplicates now left undeclared are named in the file header so the next deploy's interactive delete prompt has a documented answer instead of a guess. Refs server-26#33.
