Systematic workflow for finding, downloading, and indexing engineering literature by domain. Covers the full lifecycle: discovery via standards ledger and doc index, web search for open-access PDFs, download script generation, PDF validation, catalogue YAML creation, and handoff to the 7-phase document-index-pipeline for indexing. Use when populating a new engineering domain with reference literature or when a WRK item requires domain-specific standards and textbooks.

Legacy Standards Storage
The og_standards corpus lives at /mnt/ace/docs/_standards/ organized by org:
ABS, API, ASTM, BSI, DNV, ISO, MIL, NEMA, Norsok, OnePetro, Unknown.
Inventory DB: /mnt/ace/O&G-Standards/_inventory.db (SQLite, 6.8 GB).
Step-by-Step Procedure
Step 0 — Verify Domain Directory Exists
DOMAIN="geotechnical"# ← set your domain
LIT_DIR="/mnt/ace-data/digitalmodel/docs/domains/${DOMAIN}/literature"mkdir -p "${LIT_DIR}"ls -la "${LIT_DIR}"
If the domain is new, create standard subdirectories:
uv run --no-project python scripts/data/document-index/query-ledger.py \
--domain ${DOMAIN} --verbose
Record each standard's status: gap, done, wrk_captured, reference.
Standards with gap or wrk_captured are download candidates.
Step 2 — Query the Document Index
Search the 1M+ record index for existing documents in this domain:
uv run --no-project python -c "
import json
from collections import Counter
matches = []
with open('data/document-index/index.jsonl') as f:
for line in f:
rec = json.loads(line)
path_lower = rec.get('path', '').lower()
summary_lower = (rec.get('summary') or '').lower()
if '${DOMAIN}' in path_lower or '${DOMAIN}' in summary_lower:
matches.append(rec)
print(f'Found {len(matches)} documents')
by_source = Counter(r['source'] for r in matches)
for s, c in by_source.most_common():
print(f' {s}: {c}')
"
Prioritize og_standards and ace_standards sources — these are already local.
Step 3 — Cross-Reference Capability Map
Check what calculations exist vs. gaps in the target repo:
uv run --no-project python -c "
import yaml
with open('specs/capability-map/digitalmodel.yaml') as f:
data = yaml.safe_load(f)
for m in data['modules']:
if '${DOMAIN}' in m['module'].lower():
print(f\"Module: {m['module']} ({m.get('standards_count', '?')} standards)\")
for s in m.get('standards', [])[:30]:
print(f\" {s['status']:15s} {s['org']:8s} {s['id'][:70]}\")
"
Step 4 — Web Search for Open-Access Literature
Search for freely available PDFs across these source tiers:
Save script to: /mnt/ace-data/digitalmodel/docs/domains/${DOMAIN}/literature/download-literature.sh
Key script patterns:
Always source scripts/lib/download-helpers.sh for the download and log functions
Use set -uo pipefail (NOT set -e) — download failures should log, not abort
Guard fallible downloads with || true or || log "NOTE: ..."
Use descriptive filenames: Author-Year-Short-Title.pdf
The download function auto-skips existing files (resume-safe)
Always run --dry-run first to preview
Step 6 — Execute Downloads and Validate
# Dry run first
bash download-literature.sh --dry-run
# Execute
bash download-literature.sh
# Validate all PDFs are real PDFs (not HTML/WAF responses)
find "${LIT_DIR}" -name "*.pdf" -exec file {} \; | grep -v "PDF document"
Any file that shows "HTML document" or "ASCII text" instead of "PDF document"
is a WAF response. Move it to a _failed/ directory and add to pending_manual.
Save to specs/capability-map/research-briefs/${DOMAIN}.yaml:
uv run --no-project python scripts/data/research-literature/research-domain.py \
--category ${DOMAIN} --repo digitalmodel
Or produce manually following the template in the research-literature skill's
references/templates.md.
Step 9 — Trigger Document Index Pipeline
Hand off to the document-index-pipeline for indexing newly downloaded literature:
# Phase A — re-index to pick up new files
uv run --no-project python scripts/data/document-index/phase-a-index.py
# If full pipeline takes >5 min, queue it instead:echo"uv run --no-project python scripts/data/document-index/phase-a-index.py" \
> .Codex/work-queue/assets/${WRK_ID}/index-regen-queued.txt
The pipeline phases that follow:
Phase A: scan filesystem → index.jsonl
Phase B: LLM extraction + classification
Phase C: domain classification
Phase E: backpopulate index
See document-index-pipeline skill for full phase details.
Step 10 — Archive Dark Intelligence
For university coursework, worked examples, and methodology extractions:
mkdir -p knowledge/dark-intelligence/${DOMAIN}/
Save worked examples (problem statements + known answers) here for TDD test
generation. These are private resources — see dark-intelligence-workflow skill.
Pitfalls and Warnings
Download Pitfalls
WAF responses saved as PDF — Always validate with file *.pdf. Sites like
eagle.org (ABS) return HTML through Cloudflare WAF. The download helper saves
whatever it gets — you must check.
set -e kills download scripts — Use set -uo pipefail without -e.
The download function returns 1 on failure; with -e the script aborts on
the first 404. Guard individual downloads with || true.
Archive.org borrow-only — Some books show a download button but return 403.
Check the item page for "Borrow" vs "Download" before scripting.
Duplicate downloads across domains — Check if a standard already exists in
/mnt/ace/docs/_standards/ or another domain's literature before downloading.
Use the og_standards SQLite to search:
sqlite3 /mnt/ace/O&G-Standards/_inventory.db \
"SELECT path FROM documents WHERE path LIKE '%keyword%' LIMIT 20"
Large file timeouts — The download helper uses wget --timeout=60.
For large textbooks (>50 MB), increase timeout or download manually.
Indexing Pitfalls
pdfplumber hangs on NTFS/NFS — For batch PDF processing, use pdftotext
via subprocess, NOT pdfplumber. See WRK-1277 warning in document-index-pipeline.
Phase A must run before Phase B — New files won't be extracted/classified
until Phase A adds them to index.jsonl.
Budget awareness for Phase B — LLM extraction costs ~$0.002/doc (Haiku).
Large domain additions (100+ docs) should be batched and budget-tracked.
Catalogue Pitfalls
Every attempted resource must appear — Never silently skip a failed download.
It goes in pending_manual: with a reason (WAF, paywall, borrow-only, 404).
Validate local_path in YAML — Every local_path in the catalogue YAML
must point to an actually existing file. Script this check:
uv run --no-project python -c "
import yaml
from pathlib import Path
data = yaml.safe_load(open('knowledge/seeds/${DOMAIN}-resources.yaml'))
for section in ['textbooks', 'standards']:
for item in data.get(section, []):
p = Path(item.get('local_path', ''))
status = 'OK' if p.exists() else 'MISSING'
print(f' {status}: {p}')
"

Standards ledger queried — gap standards identified
Document index searched — existing docs catalogued
