+# First Dasha Oracle Packet Operator Card
+
+Goal: fill one external Dasha value for `template_steve_jobs_dasha_lahiri`.
+
+do not fill Shadbala in this pass. Shadbala has its own closure board and must not block the first Dasha oracle sample.
+
+## Birth Data
+
+- Date: `1955-02-24`
+- Time: `19:15:00`
+- Place: San Francisco, CA
+- Coordinates: `37.7749, -122.4194`
+- Timezone: `UTC-08:00`
+- Ayanamsa: `Lahiri`
+- Node mode: `true node`
+
+## External Tool
+
+Use one external black-box source:
+
+- JHora Vimshottari Dasha screen, or
+- PyJHora black-box output, or
+- a documented printed/software example.
+
+Do not use this repository's local engine output as evidence.
+
+## Fill This Packet
+
+Template:
+
+`references/oracle/evidence_packet_templates/dasha_steve_jobs_lahiri_first_packet_only.json`
+
+Required fields:
+
+- `status`: set to `external_verified`
+- `metadata.tool_name`
+- `metadata.tool_version_or_url`
+- `metadata.capture_date`
+- `metadata.source_artifact`
+- `metadata.operator_note`
+- `target.vimshottari_start_date`
+
+Save the redacted screenshot or stdout snippet under `references/oracle/artifacts/`.
+
+## Apply
+
+```bash
+python3 scripts/oracle_collection_queue.py \
+  --oracle-file references/oracle/dasha_shadbala_oracle_cases.json \
+  --apply-packet references/oracle/evidence_packet_templates/dasha_steve_jobs_lahiri_first_packet_only.json \
+  --format json
+```
+
+## Validate
+
+```bash
+python3 scripts/oracle_collection_queue.py \
+  --oracle-file references/oracle/dasha_shadbala_oracle_cases.json \
+  --format json > /tmp/jyotish_oracle_queue_filled.json
+
+python3 scripts/oracle_evidence_validator.py \
+  --queue-file /tmp/jyotish_oracle_queue_filled.json
+```
+
+Expected first milestone after real external evidence is filled:
+
+- Dasha closure board moves from `external_verified_dasha_tasks: 0` to at least `1`.
+- Master dashboard still keeps `can_claim_global_oracle_closure: false` until all external oracle fronts are complete.
