+# Phase 6c: Code Cleanup
+
+## Objective
+
+Remove dead code paths left over from the refactor. Investigation first,
+deletion second — only remove what's confirmed dead.
+
+## Investigation Findings
+
+### Expected dead code vs reality
+
+| Item | Expected status | Actual status |
+|------|----------------|---------------|
+| `scanner_loop` | Dead function in recon.py | **Already removed** in Phase 5c-1 |
+| `peertube_scanner_loop` | Dead function in recon.py | **Already removed** in Phase 5c-1 |
+| `crawler_scheduler_loop` | Dead function in recon.py | **Already removed** in Phase 5c-1 |
+| `organizer_loop` | Dead function in recon.py | **Already removed** in Phase 5c-1 |
+| Extract worker thread | Vestigial in cmd_service() | **Confirmed dead** — 0 items queued, silent 24h+ |
+| `lib/crawler.py` | Legacy module | **Confirmed dead** — only used by CLI subcommand |
+| `lib/web_scraper.py` | Legacy module | **ALIVE** — `chunk_text()` used by transcript_processor |
+| `lib/new_pipeline.py` | Legacy module | **ALIVE** — active Stream B library management tool (1,637 lines, created Apr 13) |
+| `lib/peertube_scraper.py` | Legacy module | **ALIVE** — only mechanism for transcript ingestion |
+| `lib/extractor.py` | Dead module | **ALIVE** — used by `cmd_run` CLI for batch processing |
+
+### Additional findings
+
+- **24 `.bak` files** found across `/opt/recon/` (untracked, manual pre-edit safety backups from Feb-Apr 2026). All originals preserved in git history.
+- **File ownership**: All 21 `.py` files + `recon.py` correctly owned by zvx. No corrections needed.
+- **No TODO/DEPRECATED comments** found in any lib/ file.
+- **All imports in recon.py** confirmed used (no dead imports at module level).
+- **PeerTube transcript ingestion** has no automatic mechanism since Phase 5c-1 removed `peertube_scanner_loop`. Ingestion is manual only (CLI or dashboard API endpoint).
+
+## What Was Removed
+
+### recon.py edits (-89 lines, +3 lines)
+
+1. **Extract worker thread** removed from `cmd_service()`:
+   - `from lib.extractor import run_extraction` import
+   - `extract_workers` variable
+   - `'extract': 0` from totals dict
+   - Extract `threading.Thread(target=stage_loop, ...)` from thread list
+   - Extract workers from startup log message
+
+2. **`cmd_crawl` function** deleted (65 lines) — CLI handler for `recon crawl`
+
+3. **Crawl argparse subparser** deleted (15 lines) — `recon crawl` subcommand registration
+
+4. **Docstring** updated to remove `crawl` from subcommand list
+
+### Files deleted
+
+| File | Lines | Reason |
+|------|-------|--------|
+| `lib/crawler.py` | 432 | Only referenced by deleted `cmd_crawl` CLI subcommand |
+
+### .bak files deleted (24 files, untracked)
+
+| File | Size |
+|------|------|
+| `recon.py.bak-pre-streamb` | 48K |
+| `recon.py.bak-pre-ux` | 35K |
+| `recon.py.bak-pre-crawler` | 35K |
+| `recon.py.bak.202602171647` | 33K |
+| `config.yaml.bak-pre-crawler` | 4K |
+| `config.yaml.bak-pre-streamb` | 13K |
+| `lib/api.py.bak` + 5 more api.py backups | 498K total |
+| `lib/embedder.py.bak` | 15K |
+| `lib/enricher.py.bak` | 17K |
+| `lib/extractor.py.bak` | 18K |

+| `static/js/dashboard.js.bak` | 11K |
+| `static/js/peertube.js.bak.20260223` | 5K |
+| `templates/search.html.bak` | 2K |
+| `templates/knowledge/dashboard.html.bak` | 3K |
+
+## What Was Kept (and why)
+
+| Module | Lines | Why kept |
+|--------|-------|----------|
+| `lib/web_scraper.py` | 324 | `transcript_processor.py` imports `chunk_text()` |
+| `lib/new_pipeline.py` | 1,637 | Active Stream B library management CLI (created Apr 13) |
+| `lib/peertube_scraper.py` | 580 | Only way to ingest PeerTube transcripts |
+| `lib/extractor.py` | 601 | Used by `cmd_run` CLI for batch PDF processing |
+
+## Verification
+
+| Check | Result |
+|-------|--------|
+| Compile (recon.py) | OK |
+| Import (recon module) | OK |
+| Import (dispatcher, filing, processors) | OK |
+| cmd_service assertions | extract worker absent, dispatch_loop present, filing_worker_loop present |
+| Zero crawler references in .py files | Confirmed |
+| Service restart | Clean, active |
+| Thread count | 13 tasks (was 14 — extract removed) |
+| Threads started | enrich, embed, dispatcher, filing, progress, dashboard, metrics |
+| Extract thread | Absent (confirmed by logs: no `[extract] Stage started`) |
+| Errors (60s window) | 0 |
+| DB rows | catalogue=29,812, documents=29,812 (unchanged) |
+| Dashboard | Responsive |
+| Hopper | Empty |
