Decompose the deal. Classify every component. Cite every conclusion.
Paste the transaction summary. The tool breaks the U.S. business into its constituent technologies, classifies each against the CCL and the USML, screens the counterparties against eleven restricted-party lists, and produces a filing-trigger memorandum — with the verbatim regulation behind every claim.
Apex Acquirer Ltd. (CN, PE fund) is acquiring 51% of Helios Microwave Corp., a Delaware-headquartered designer of GaN-on-SiC RF power amplifiers used in radar and SATCOM modules. Helios sells into DoD primes (Raytheon, Northrop) and commercial 5G OEMs. The deal includes the wafer-process IP, firmware libraries, and a customer dataset of recorded radar signatures.

The hero shows the four components decomposed from one transaction. Here is the pipeline that produced a single one of them — the same pipeline runs for every component, in parallel.
Designed in-house at Helios Microwave Corp. (Delaware). Fabricated at TSMC Taiwan on a GaN-on-SiC process. Used in radar and SATCOM modules. Sold to DoD primes (Raytheon, Northrop) and commercial 5G OEMs.

“monolithic microwave integrated circuit power amplifier rated for operation at frequencies exceeding 31.8 GHz”
Nine-category enum
Hardware, software, algorithms, data, firmware, cryptographic modules, FPGA configurations, services, and IP — each component is split by kind, then classified separately.
EAR Order of Review walk
When a component doesn't match a Category-3-through-9 entry, the classifier walks the EAR Order of Review (15 CFR § 738) deterministically to EAR99 or USML referral.
Threshold language verbatim
No paraphrases. The verbatim controlling text — “rated for operation at frequencies exceeding 31.8 GHz” — is what the run footnotes cite.
Restricted-party screening that runs on every analyze, before classification.
600 ms debounced. Blocking-severity hits — OFAC SDN, BIS Entity List, DoD § 1260H — gate the run before any tokens are billed.

Covered investment
Deterministic § 800.210 / .211 walk through control rights, governance rights, and covered-investment rights. No LLM in the gating logic.
TID determination
Critical-technology match against indexed § 800.215, critical-infrastructure LLM-judged against Appendix A, SPD against § 800.241 thresholds.
Shot-clock math
Subpart F deadline arithmetic anchored to the binding-agreement date — declaration, review, investigation, Presidential decision.

I. Covered transaction determination
The proposed transaction is a COVERED CONTROL TRANSACTION within the meaning of 31 CFR § 800.210 because Acquirer X, a FOREIGN PERSON organized under the laws of the People’s Republic of China, will acquire 51% of the voting interests of Target Y, a U.S. BUSINESS engaged in the design and manufacture of advanced semiconductor packaging.1
Target Y is a TID U.S. BUSINESS under § 800.248 by virtue of its production of CRITICAL TECHNOLOGIES controlled under 15 CFR Part 774, Category 3A — specifically 3A001.a.7 (microwave monolithic integrated circuits).2
