Open the full glossary- PATH and file pathsA path is a file's address. PATH is the list of folders the computer searches when you name a program.
- Vector databaseA database that searches by how close the meaning is: you give it a query vector and it returns the nearest few records, instead of matching exact wording.
- Full-text searchTraditional keyword search that ranks by whether terms appear, how often, and how rare they are; the classic algorithm is BM25. It does not understand meaning — it counts words.
- Semantic vs keyword searchThe core trade-off between two retrieval styles: keyword matches on whether wording is identical, semantic on whether meaning is close. The former is precise but rigid; the latter is flexible but can miss the point.
- Hybrid SearchHybrid Search combines semantic vectors and keyword signals and merges the results, balancing similar meaning with exact names.

Agentic Attack Tooling Research Series: A Guide to All Fourteen Parts
When attack tooling becomes AI-agent-driven, both sides of the conflict change. This is a fourteen-part deep research series: starting from a publicly attributed real-world incident, it unpacks architecture design, coordination mechanisms, and technical principles, then returns to a checklist defenders can use immediately plus isolated research practice.
When AI Learns to Pentest: The ARTEX Case and the Rise of Agentic Attack Tooling
In October 2026, an open-source AI pentesting tool called ARTEX was linked to attacks on South Korean financial institutions — and within 48 hours its developer pulled the source and went closed-source. This article reconstructs the timeline, unpacks its technical positioning, and answers the more important question: how should defenders respond when attack tooling is driven by AI agents?
The Double-Graph Architecture: Separating "What the Target Is" from "How Far We Have Tested"
Most automation systems track progress in a single state table — and end up with facts and reasoning contaminating each other: unverified guesses get treated as confirmed assets, and work proceeds on false premises. This article unpacks a rare design that splits the truth store from the per-task reasoning chain into two graphs joined by anchors — and why that pattern deserves attention from any long-running AI agent system.
Honeypots and Anti-Agent Traps: When the Prey Starts Setting Traps
Honeypots are a classic defensive tool, but once attackers became AI agents both sides changed: defenders now design traps aimed specifically at AI, and anyone using agents to read external content needs to know how to avoid them. This article unpacks four trap classes and how to defend against them.
Isolated Research Practice: How to Study an Offensive Tool Safely
Studying offensive tooling is a necessary part of security work, but "researching" and "using" must be separated by technical boundaries, not willpower. Using a real isolated deployment as the example, this article covers network isolation, port binding, resource limits, tool verification, and five red lines.

A Map of HK Equity Research Sources: HKEX Filings, Annual Reports, and Third-Party Data
When researching an HK-listed company, where does the information come from, which sources are trustworthy, and which can only serve as leads? This article divides HK equity research sources into five credibility tiers — statutory disclosures, company-produced information, third-party databases, market data sources, and news and research reports — and provides a 'question-to-source' mapping table.
Compliance Boundaries for Investment-Research AI: Disclaimers, Audit Trails and Traceability
When you put AI into an investment-research workflow, compliance is not one disclaimer line at the end of a report — it is a system-design problem: does the output constitute investment advice, are the data sources licensed, and can every conclusion be traced back to its inputs and prompt versions. This article gives a risk-dimension inventory, an audit-trail architecture, human-review checkpoint design, a question list to take to legal, and a route for strengthening internal policy.
Hallucination Risk in Finance: The Three Most Expensive Mistakes
The cost of AI hallucination in financial scenarios is severely underestimated. This article dissects the three most expensive mistakes — fabricating numbers, confusing periods and companies, and filling gaps with inference — explains what causes each one, and gives four implementable lines of defense: mandatory citation, separate statistics, low-confidence abstention, and human review.
How to Read an Error Message: Anatomy, Stack Traces, and Exit Codes
Error messages aren't meant to be read word by word — they have a fixed shape: a concluding line, a stack trace, a filename with a line number, and an exit code. This article teaches why you read a stack trace bottom-up, how to find the line that actually failed, six real-shaped examples, and when to paste the whole thing into a search engine, when to give it to an AI Agent, and when to do neither.
Shareholding Topology and Double-Count Prevention: Computing Shareholdings Under Group Structures
Under a group structure, directly adding up the shareholding percentages of different layers is the most common — and most fatal — calculation error. Using a fictional teaching structure, this article demonstrates the layer-by-layer dilution computation of economic interest, voting attribution along the control chain, and the simultaneous solving of cross and circular shareholdings, and gives a method for building the shareholding structure into a queryable graph plus a double-count-prevention checkpoint list.

Automating Comparable Company Analysis: Run an Entire Sector in One Pass
The difficulty in comparable company analysis is not the arithmetic of multiples but the basis: fiscal year, currency, one-off items, and EV composition can all let two companies' numbers contaminate each other. This article breaks down the criteria for selecting peers, six categories of basis-unification rules, and the traps in choosing multiples, and gives a five-stage automation pipeline design with executable code, from data extraction to outlier handling.
DCF Assumptions and Sensitivity Analysis: Make the Valuation Challengeable
The value of a DCF is not in computing one number but in whether the assumptions behind it can be examined, challenged, and recomputed. Using a hypothetical model for teaching, this article demonstrates the assumptions register, the three-stage cash-flow structure, the composition facets and trade-offs of WACC, the risks of the two terminal-value methods, the design of single-factor and two-factor sensitivity matrices, and how to present a valuation as a defensible range rather than a fragile single point.
