Four steps for the browser route, the server route for anyone who would rather their key lived in an environment variable, base URLs for LM Studio, Ollama, llama.cpp and vLLM, and a table of what the errors mean. **License** puts the terms in the file rather than only on this site, so a copy that has been passed around can still say what it is: Apache 2.0 code, CC BY 4.0 data, MIT and CC BY for the two upstream corpora, public domain for the decisions, plus a citation to copy. Both are on [/nexus](https://acqagent.ai/nexus#whats-new) in a new section, with screenshots. The full bundle is [marked coming soon](https://acqagent.ai/nexus#full-bundle) rather than linked, because it is being rebuilt against v2.1. Until the new one lands, the setup steps clone the [repository](https://github.com/acqagent/GAO-Bid-Protest-Nexus) and build the vector index locally, which is the one thing the repository does not carry. ## 2026-09-19 — Nexus v2.1 The hosted [dashboard](https://acqagent.ai/nexus/dashboard) is now v2.1, built with a dedicated web flag rather than the plain static build. The practical difference is the two model-backed tabs. They are both present now, and they behave differently from each other. **Dynamic Search** shows its tab but states that it is not part of a hosted copy: the vector index over the full decision text is far too large to ship inside a web page and needs a server behind it. It still works in the [downloadable bundles](https://acqagent.ai/nexus). **Analysis** does run here, against any OpenAI-compatible endpoint you point it at, with your key kept in your own browser and the decision text or PDF supplied by you. Because the build knows it is hosted, it no longer probes a backend that is not there, so the site stops logging a 404 on every pageview. The homepage gained screenshots of both tabs, and all the screenshots now link to this page rather than dropping straight into the dashboard. ## 2026-09-19 — Nexus v2.0, in the browser The [GAO Bid Protest Nexus](https://acqagent.ai/nexus/dashboard) now opens straight in a browser at [/nexus/dashboard](https://acqagent.ai/nexus/dashboard). No download, no Python, no server. The corpus grew from 5,986 decisions to **33,136**, and the facets from four to eight: ground, outcome, procurement authority, protest posture, decade, PDF source, text source and digest. Two features are not in this build. Dynamic Search over the complete decision text and the AI analysis and comparison tabs both need a local server, so they stay in the [downloadable bundles](https://acqagent.ai/nexus), which still cover the smaller 5,986-decision corpus. The build is candid about what it cannot yet tell you, and the page says the same: 82% of ground assignments are model-assigned rather than reviewed, half the corpus has no recorded outcome so sustain rates cover a subset, and 27,239 decisions link to a gao.gov landing page rather than straight to the PDF. Accuracy and every feature are under active improvement. Licensing changed with the release. From v1.0 forward the code is Apache 2.0 and the data — taxonomy, per-decision coding, metadata, vector index — is CC BY 4.0. Earlier releases stay available under CC BY 4.0 in full. ## 2026-09-15 — A page for contributing Added [/contribute](https://acqagent.ai/contribute). The Contribute link in the navigation used to drop straight onto the GitHub organization, which is a poor answer to "how do I help?" — it shows repositories without saying which take contributions or what is actually useful. The page names the four that do (`skills`, `GAO-Bid-Protest-Nexus`, `mcps`, `agents`), ranks the kinds of contribution by how rare they are rather than how hard, and walks through opening a pull request. Corrections can be emailed in instead, for anyone without a GitHub account. The Contribute card is back on the homepage, pointing at the page rather than off-site. ## 2026-09-15 — The Nexus gets its own page The [GAO Bid Protest Nexus](https://acqagent.ai/nexus) moved off the examples page to [/nexus](https://acqagent.ai/nexus), with the downloads, the screenshots and the setup walkthrough all in one place. The examples page keeps the FAR Part 52 P&C Tracker and points at the new page. The homepage was rearranged around it: the Nexus now leads with a preview of the dashboard, followed by the category cards — Nexus, MCPs, Skills, Examples and Resources. MCP servers are marked coming soon. The Contribute card is gone, since the section it sat in is the invitation; the link stays in the navigation. ## 2026-09-13 — Nexus decision analysis The [GAO Bid Protest Nexus](https://acqagent.ai/nexus) gained a fifth tab. Analysis reduces a decision to its key elements — parties, solicitation, authority and posture, the grounds raised and GAO's ruling on each — or reads a selection of up to twelve against each other as a side-by-side comparison. It runs on any OpenAI-compatible endpoint, including a model on your own machine, and everything it does is also available headless from a terminal. Both bundles were rebuilt. PDF links now resolve directly for 5,921 of the 5,986 decisions instead of going through a gao.gov landing page, and the full bundle's server feeds Analysis straight from the search index, so summarizing a decision fetches nothing. ## 2026-09-08 — GAO Bid Protest Nexus Published the [GAO Bid Protest Nexus](https://acqagent.ai/nexus): 5,986 GAO bid protest decisions coded against 33 protest grounds, as an interactive dashboard. The basic bundle is a single self-contained HTML file that runs offline with no server; the full bundle adds a hybrid search backend over the complete decision text. Per-ground sustain rates ship with 95% confidence intervals against the 12.2% corpus base rate, because most of the apparent spread between grounds is sampling noise. ## 2026-07-29 — FAR Clause Checker v3 Shipped v3 of the [FAR Clause Checker](https://acqagent.ai/skills/far-clause-checker) and corrected the install instructions. The skill validates FAR 52.2xx and HHSAR 352.2xx clause lists against the acquisition.gov Smart Matrix and the JUL 2026 HHSAR Deviations matrix, then writes a standalone .docx compliance report.
