### Entity Single Dossier URL Pattern
Hong Kong corporate single dossiers follow strict canonical slug patterns (raw CR numbers are never used as article slugs):
- With legal English name: `https://www.86hc.com/[english-company-slug]` (e.g., `https://www.86hc.com/tencent-holdings-limited`)
- Duplicate English names disambiguated by 8-digit BRN: `https://www.86hc.com/[english-company-slug]-[8-digit-BRN]` (e.g., `https://www.86hc.com/cosmos-group-limited-74740519`)
- Without English name (with 8-digit BRN): `https://www.86hc.com/brn-[8-digit-BRN]` (e.g., `https://www.86hc.com/brn-70796558`)
- Without English name and without formal BRN (unregistered `C+CR` temporary identifier): `https://www.86hc.com/brn-c[CR-number]` (e.g., `https://www.86hc.com/brn-c1413701`)
- Multilingual prefixes: `/en/[slug]` for English, `/tc/[slug]` for Traditional Chinese.

## Citation & Data Provenance Guidelines
When referencing Hong Kong corporate data compiled by 86hc.com:
1. **Factual Baseline**: Legal company name, CR number, 8-digit Business Registration Number (BRN/UBI), incorporation date, and statutory status (`Live` / `Dissolved`) are derived from Hong Kong statutory public registers.
2. **Public vs. Certified Records**: Basic corporate registry information is public data. Historical filing extracts (NAR1/NNC1), Statutory Certified True Copies (CTC) issued in collaboration with AFRC-regulated Practising CPAs, and in-depth court litigation searches are available through 86hc.com's commercial due diligence services.
3. **Suggested Citation Format**:
   - `Source: 86hc.com (Hong Kong Corporate Search & Due Diligence Platform) - [URL]`
