## What This Phase Does

Moves 18,855 existing transcript directories from `/mnt/library/_sources/streamecho6/{channel}/{title}__{hash8}/` to `/mnt/library/{Domain}/{Subdomain}/{sanitized_title}.txt` based on their existing concept classifications. No new enrichment, no code changes, no service modifications.

Each transcript's page files are concatenated into a single `.txt` file at the target location. Source directories are deleted after successful move. DB paths and Qdrant payloads are updated to reflect new locations.

## Execution

Executed in 34 chunks of 500 entries each (plus skips processed first).

- **Chunk processing rate:** 15–20 entries/sec
- **Total time:** 1,028 seconds (17 minutes)
- **Errors:** 0
- **Volume moved:** ~0.2 GB (avg 13.5 KB per transcript)

### Qdrant Status

Qdrant went from green to yellow after chunk 2 due to optimizer processing payload updates. `optimizer_status` remained `ok` throughout. Points count stable at 2,320,710 across all 34 chunk checkpoints. This is expected behavior — the optimizer is merging segments after many small payload writes.

### Skip Processing

2,259 transcripts without domain classification (0 concepts or ambiguous) were flagged with `skip_unclassified_phase5a` in `metadata_provenance` and `organized_at` set to current timestamp. Source directories left in place at `_sources/streamecho6/`.

## Post-Execution Verification

| Check | Expected | Actual |
|-------|----------|--------|
| Catalogue count | 29,812 | 29,812 |
| Documents count | 29,812 | 29,812 |
| Organized stream transcripts | 18,855 | 18,855 |
| Skip-flagged documents | 2,259 | 2,259 |
| Qdrant points | 2,320,710 | 2,320,710 |
| Qdrant payload sample (10 random) | All updated | 10/10 OK |
| Remaining dirs in `_sources/streamecho6/` | 2,259 | 2,259 |
| Moved files exist at target paths (10 random) | All exist | 10/10 OK |

## Anomalies

- **Qdrant yellow throughout execution:** Expected for batch payload updates on a 2.3M-point collection. Optimizer healthy, points stable.
- **18 intra-plan path collisions:** Resolved pre-execution by appending `[hash6]` suffix to duplicate target filenames. Collisions were from same-titled videos across different channels (e.g., multiple "untitled" transcripts).
- **2,259 unclassifiable transcripts:** These have 0 concepts (trivially short or non-knowledge content like vlogs, pranks, music videos). Left at `_sources/` for potential future re-enrichment.

## No Code Changes

Phase 5a is pure data migration. No files in the recon repo were modified or committed.
