+# Issue #582 Verification — Parent-Epic Orchestration Slice
+
+**Date:** 2026-04-14
+**Status:** ✅ Verified on `main`
+**Refs:** #582, #789, #795
+
+## Summary
+
+The parent-epic orchestration slice for the Know Thy Father multimodal pipeline is **already implemented on `main`**. This document records the verification evidence.
+
+## What Exists
+
+### Core Orchestrator
+- **File:** `scripts/know_thy_father/epic_pipeline.py`
+- **Function:** Builds and executes a 5-phase pipeline plan; reports status snapshots
+- **Phases:**
+  1. Media Indexing (`scripts/know_thy_father/index_media.py`)
+  2. Multimodal Analysis (`scripts/twitter_archive/analyze_media.py`)
+  3. Holographic Synthesis (`scripts/know_thy_father/synthesize_kernels.py`)
+  4. Cross-Reference Audit (`scripts/know_thy_father/crossref_audit.py`)
+  5. Processing Log (`twitter-archive/know-thy-father/tracker.py`)
+
+### Supporting Scripts (All Present)
+| Script | Purpose |
+|--------|---------|
+| `scripts/know_thy_father/index_media.py` | Phase 1 — scan tweets, emit media manifest |
+| `scripts/twitter_archive/analyze_media.py` | Phase 2 — batch multimodal analysis |
+| `scripts/know_thy_father/synthesize_kernels.py` | Phase 3 — kernels → Father's Ledger |
+| `scripts/know_thy_father/crossref_audit.py` | Phase 4 — cross-reference against SOUL.md |
+| `twitter-archive/know-thy-father/tracker.py` | Phase 5 — processing log / status report |
+
+### Test Coverage
+- `tests/test_know_thy_father_pipeline.py` — orchestrator structure
+- `tests/test_know_thy_father_index.py` — Phase 1 logic
+- `tests/test_know_thy_father_synthesis.py` — Phase 3 logic
+- `tests/test_know_thy_father_crossref.py` — Phase 4 logic
+- `tests/twitter_archive/test_ktf_tracker.py` — Phase 5 tracker
+- `tests/twitter_archive/test_analyze_media.py` — Phase 2 analysis
+
+## Why `Refs #582`, Not `Closes #582`
+
+The repo-side operational slice is complete, but the parent epic (#582) also encompasses:
+- Full archive consumption (not yet finished)
+- Downstream memory integration (pending)
+
+Therefore #582 remains open; this evidence trail closes the verification sub-issues (#789, #795).
+
