SEC EDGAR Supply Chain & Counterparty Mapper — Cited supplier, customer & foundry maps straight from SEC filings.

Map who a public company says it depends on and who depends on it: disclosed suppliers, major customers at or above the 10% threshold, foundry and compute partners, Exhibit 21 subsidiaries, Inline-XBRL concentration risk (CR-01 to CR-04), year-over-year 10-K counterparty changes, and Schedule 13D/13G equity stakes (EQ-01). Every edge carries a verbatim quote of 300 characters or fewer, the accession number and a direct SEC Archive URL.

Architecture, Data Sources & Execution Capabilities

Typed, cited relationship edges: supplier, customer, foundry_compute, strategic_partner, subsidiary and equity_stake, each with a verbatim quote of <=300 characters, the accession number and the direct sec.gov Archive URL. No quote, no edge.
Inline-XBRL Disclosed Concentration Scorer (CR-01 to CR-04): reads us-gaap:ConcentrationRiskPercentage facts (major-customer and product axes) for customer, top-customer, sole-source supplier and receivables concentration. Exhibit 21 subsidiaries are separated so they are never counted as customers or suppliers.
YoY 10-K Counterparty Diff: ADDED, REMOVED and PCT_CHANGED counterparties between the two latest annual reports, with both accession numbers.
Schedule 13D/13G Equity Stakes (EQ-01): 5% or greater positions between registrants, with filer, percentage, filing date and accession number. Multi-company runs and presets such as --preset nvidia-physical-ai map a whole ecosystem in one pass.
Hardened stdlib fetch: HTTPS-only sec.gov allow-list, DNS pinning, no redirects, SEC-compliant User-Agent, at most 5 requests per second, and request and byte caps. Python 3.10+ standard library only; --json / --markdown output.

Verbatim Sample Output (`sec_supply_chain_mapper.py --preset nvidia-physical-ai`)

Sample disclosure: this is a representative sample, not a customer report. Percentages, quotes and accession numbers (shown as 000###) are illustrative placeholders and were not retrieved from EDGAR for this page; counterparties marked fictional do not exist. Your own report will cite real filings and differ in content and length.

SCOPE_NOTE: Primary SEC EDGAR filings only. Relationships are reported only where a filing quote supports them; private contracts, undisclosed counterparties and non-filing sources are out of scope. Concentration scores summarise disclosed percentages and are not a credit, investment or valuation opinion. No buy, sell or hold ratings.

What This Bot Does Not Do (Mandatory Refusal Boundaries)

Never states a supplier, customer or partner relationship unless a filing quote supports it; anonymous 'Customer A' disclosures are never matched to a guessed company.
Never outputs stock buy, sell or hold ratings, valuation multiples, forecasts or price targets, and never presents a concentration score as a credit or investment opinion.
Never fetches non-SEC hosts, follows redirects, or exceeds SEC EDGAR rate limits; refuses private-IP and non-HTTPS targets.
Always prepends a SCOPE_NOTE: private contracts, undisclosed counterparties and non-filing sources are outside primary filings.

Turn-1 `/workspace` Onboarding & Non-Custodial Licensing

One-time $29 license with up to 3 workspace-reset rebinds, also included in the Institutional EDGAR Intelligence Pack ($89) with the Company & Competitor Deep-Dive Analyst and the SEC & Patent Watchdog Digest. On Turn 1 the sec-supply-chain-mapper-setup skill installs the read-only license helper, provisions /workspace/.wattcoin_env (0600) and binds your wcl_... license. The license code is never printed in chat.

One wcl_... key, two runtimes. Your license key works inside Grok Bot and from any local terminal or IDE agent (Cursor, Claude Code, Windsurf, CI/CD) via the standalone single-file Python 3 CLI (standalone /runtime/<script>.py CLI) — Python 3.10+ standard library only, zero pip install dependencies, with --json / --markdown output.

Frequently Asked Questions — SEC EDGAR Supply Chain & Counterparty Mapper

How does the SEC EDGAR Supply Chain Mapper extract verified customers, suppliers, and foundry partners without hallucinating?

It never infers a relationship. The mapper reads primary SEC EDGAR filings only (10-K, 10-Q, 8-K, Exhibit 21, Schedule 13D/13G) and emits an edge only when a sentence in the filing text names the counterparty and the relationship. Every edge is typed (supplier, customer, foundry_compute, strategic_partner, subsidiary or equity_stake) and carries a verbatim quote of at most 300 characters plus the accession number and a direct sec.gov Archive URL. If a filing says 'Customer A' without a name, it is reported as an anonymous customer with its disclosed percentage, never matched to a guessed company. Output ends with an audit_sha256 so a run can be reproduced and compared.

How does the Inline-XBRL Disclosed Concentration Scorer (CR-01 to CR-04) and Exhibit 21 subsidiary separation work?

The scorer reads Inline-XBRL facts from the filing itself (for example us-gaap:ConcentrationRiskPercentage with the srt:MajorCustomersAxis and srt:ProductOrServiceAxis dimensions) instead of scraping prose. CR-01 flags a single customer at or above the 10% disclosure threshold, CR-02 flags the top disclosed customers combined, CR-03 flags sole-source or single-source supplier disclosures, and CR-04 flags receivables concentration. Exhibit 21 is parsed separately, so legal subsidiaries are labelled subsidiary and are never counted as customers, suppliers or partners.

What do the YoY 10-K Counterparty Diff and Schedule 13D/13G Equity Stake (EQ-01) checks detect?

The YoY diff compares the counterparty set and disclosed percentages between the two most recent 10-Ks and labels each change ADDED, REMOVED or PCT_CHANGED, so a new major customer, a dropped supplier or a shift in revenue share is visible with both accession numbers. EQ-01 reads Schedule 13D and 13G filings to report equity stakes of 5% or more between the target and another registrant, with the filer, the percentage, the filing date and the accession number. A stake is reported as a fact from the filing; it is not interpreted as control or a commercial relationship.

What SSRF, rate-limit, and refusal guardrails does sec_supply_chain_mapper.py enforce?

The CLI is HTTPS-only and allow-lists sec.gov hosts (data.sec.gov, www.sec.gov, efts.sec.gov), resolves and pins DNS before connecting, and refuses redirects, private or link-local addresses and any non-allow-listed URL, which blocks SSRF. It identifies itself with a compliant SEC User-Agent and stays at or below 5 requests per second with a hard request and byte cap per run. It never outputs buy, sell or hold ratings, price targets or forecasts, never states that a relationship exists unless a filing quote supports it, and prepends a SCOPE_NOTE that private contracts and undisclosed counterparties are outside primary filings.
