+# AGENTS.md — CoNexDat website
+
+Instructions for AI coding agents (Claude Code, Copilot, Codex, Cursor, ...) working in
+this repository. `CLAUDE.md` includes this file. Humans: see `CONTRIBUTING.md`.
+
+## What this project is
+
+The public website of CoNexDat, the Complex Networks and Data Communication Group at
+the School of Engineering of the University of Buenos Aires (FIUBA), directed by
+J. Ignacio Alvarez-Hamelin. It is a static Jekyll 4 site built on the academicpages
+template, trilingual (Spanish default, English, French) through jekyll-polyglot, with
+publications rendered from BibTeX by jekyll-scholar. GitHub Actions builds it and
+publishes `_site/` to the `gh-pages` branch, served at <https://conexdat.github.io>.
+It replaces the legacy site at `cnet.fi.uba.ar`, which is being retired.
+
+## Layout
+
+```
+_config.yml                 site, polyglot and scholar settings; cnet.highlighted_authors
+_config.dev.yml             local overrides (url: http://localhost:4000); required for previews
+_pages/<page>.md            Spanish page; <page>.en.md and <page>.fr.md are the translations
+_data/
+  members.yml               people, by category (current, external, former-inhouse, ...)
+  projects.yml              funded projects
+  research_areas.yml        research areas: home cards + /research/<slug>/ pages
+  highlights.yml            home-page project cards
+  publication_topics.yml    publication topics (labels), trilingual
+  theses.yml, navigation.yml, ui-text.yml
+_news/                      one file per news item and language (inline, no pages)
+_bibliography/conexdat.bib  THE publication list (other .bib files are unused sources)
+_layouts/bib_entry.html     how one publication renders (buttons, highlighting, topic chips)
+_includes/                  masthead (language switcher), people/projects/theses lists,
+                            publications-filter.html, research-area.html
+assets/js/publications.js   search / topic / person filter on /publications/
+_sass/_conexdat.scss        all site-specific styles (colors, cards, chips, dark mode)
+.github/workflows/          build.yml (PR check "Build site"), deploy.yml (push to main)
+```
+
+## Commands
+
+```bash
+export PATH="/usr/local/opt/ruby@3.3/bin:$PATH"   # macOS/Homebrew; Ruby 3.3 only
+bundle install
+bundle exec jekyll serve --livereload --config _config.yml,_config.dev.yml   # preview
+JEKYLL_ENV=production bundle exec jekyll build                              # what CI runs
+```
+
+Ruby 3.3 is required: the system Ruby is too old for Bundler 4, and Ruby 4 cannot
+compile the `sassc` native gem. A full build takes about 30 seconds. The repeated
+"Error reading file _layouts/single" warnings are a harmless polyglot quirk. To preview
+a finished build without Jekyll, serve `_site/` on **port 4000**; the dev config
+hard-codes that origin for CSS and assets.
+
+## Conventions
+
+- **American English everywhere** (mandatory) for English text: the `.en.md` pages, the
+  `en:` values in `_data/`, English news, this file, README, CONTRIBUTING, commit
+  messages, PR descriptions, and every code comment, identifier, CSS class and
+  JavaScript name (`color`, `gray`, `center`, `behavior`, `modeling`, `analyze`,
+  `visualize`, `normalize`, `organization`, `toward`, `inquiry`). Spanish and French
+  content stays in correct Spanish and French. Exceptions: proper names and published
+  paper titles in the bibliography are kept exactly as published.
+- **Three languages in lock-step.** Every content change updates Spanish, English and
+  French together: the three `.md` files of a page, or the `es:` / `en:` / `fr:` keys of
+  the same YAML entry. Never ship a page or entry in one language only.
+- **No e-mail addresses anywhere on the site** (group decision, September 2026). The
+  contact page points to the director and to <https://github.com/CoNexDat>. Do not add
+  `mailto:` links, and keep `author.email` in `_config.yml` empty.
+- **Do not link into `cnet.fi.uba.ar`.** Unknown paths there silently serve the legacy
+  home page, so a link can look alive and still be wrong. Pages that still exist there
+  and may be linked: `netscix23/`, `SnailVis/`, `PIT/…`, `PaD/`. Otherwise use the
+  project's new home (TiX: <https://github.com/TiX-measurements>, LaNet-vi:
+  <https://github.com/CoNexDat/LaNet-vi>, TMA2018: <https://netcores.fi.uba.ar/>) or a
+  Wayback Machine snapshot. Check with `grep -rn cnet.fi.uba.ar _data _pages _news`.
+- **Verify every new external link** with `curl -sIL` and read where it lands: a 200 on
+  a home page, a sign-in wall or a parked domain is a broken link.
+- **Publications**: add entries to `_bibliography/conexdat.bib` with a
+  `topics = {id1, id2}` field using ids from `_data/publication_topics.yml` (add a new
+  topic there, in three languages, only when no existing one fits). Two 1990s
+  instrumentation papers (`onditas96`, `Thermog95`) are deliberately untagged: no topic
+  fits them, and they only disappear while a topic filter is active. Prefer a bare DOI
+  (`10.xxxx/…`), `eprint` + `archiveprefix = {arXiv}` for preprints, and check the key is
+  not already present: the group's own exports contain duplicates.
+- Internal links are written without language prefix (`/projects/`); polyglot adds
+  `/en/` or `/fr/`. Do not hard-code `https://conexdat.github.io/...` in content.
+- Commit messages and PR descriptions in American English, imperative subject line.
+
+## Things that are easy to get wrong
+
+- **Language switcher.** Polyglot rewrites every `href="/…"` on EN and FR pages into the
+  current language, which breaks hand-written ES | EN | FR links. The masthead writes them
+  as `ferh="/en/…"`, which polyglot turns back into `href` untouched. Do not rename the
+  attribute. The `Build site` workflow greps the output for the expected hrefs.
+- **No `//` comments inside inline `<script>` blocks.** Production builds compress HTML
+  onto one line, so a `//` comment swallows the rest of the script. That silently broke
+  the previous language switcher. Use `/* … */` or move the code to `assets/js/`.
+- `assets/js/main.min.js` is a prebuilt file; `assets/js/_main.js` and `plugins/` are
+  excluded from the build, so editing them changes nothing.
+- `jekyll-sass-converter` is pinned to 2.x on purpose: the academicpages partials do not
+  compile under dart-sass (3.x). Dependabot is told to ignore that major version.
+- Jekyll-scholar exposes custom BibTeX fields (`topics`, `pdf`, `code`, ...) to
+  `_layouts/bib_entry.html`; the same template renders the short paper lists on research
+  area pages, so keep it free of page-specific assumptions.
+
+## Pull request workflow (required)
+
+`main` is protected by the "Protect main" ruleset: no direct pushes, no force-push or
+deletion, pull request required, and the `Build site` check must pass. Repository
+admins can bypass; do not use the bypass unless a maintainer explicitly asks for it in
+an emergency, and say so in the PR description.
+
+1. Branch from `main` (`feat/…`, `fix/…`, `content/…`, `docs/…`, `chore/…`), commit,
+   push, open the PR with `gh pr create`, and fill the PR template checklist honestly.
+2. Build locally before pushing. For visual changes, check ES, EN and FR in the browser,
+   in light and dark mode, and at phone width.
+3. Wait for `Build site`. If it is red, read the log (`gh run view <id> --log-failed`),
+   fix, push, and wait again. Never weaken the check to get green.
+4. Get a review before merging (see CLAUDE.md for how Claude Code sessions do this).
+5. Merge with `gh pr merge <n> --squash --delete-branch`. Merging deploys to production
+   within a few minutes; confirm the live page afterwards.

+
+## Claude Code way of working
+
+Every PR is reviewed by a **fresh-context reviewer subagent** before merging:
+
+1. Push the branch, open the PR, and wait for the `Build site` check.
+2. Spawn a **new** reviewer with the Agent tool: `model: "sonnet"`,
+   `isolation: "worktree"`, and a self-contained prompt with the repository, the PR
+   number, `gh pr diff <n>`, the conventions in AGENTS.md, the checks to run (the
+   production build with Ruby 3.3, link checks with `curl -sIL` on every added URL, a
+   British-spelling scan of English text), "read-only, do not modify the repository",
+   and the required output: findings ranked by severity with `file:line`, a concrete
+   failing scenario and a suggested fix, ending with exactly `VERDICT: APPROVE` or
+   `VERDICT: CHANGES REQUESTED`.
+3. Verify each finding before acting on it. Fix it (commit and push) or record in a PR
+   comment why it does not apply.
+4. After any change, spawn **another fresh** reviewer for the new state; never continue
+   the previous reviewer session.
+5. Merge only when the check is green on the latest push **and** the latest reviewer
+   says `VERDICT: APPROVE`. Post a PR comment summarizing the review rounds, then merge
+   with `gh pr merge <n> --squash --delete-branch` and confirm the live site.
+
+The site belongs to the group director, J. Ignacio Alvarez-Hamelin, and is maintained by
+Esteban Carisimo. Feedback from the director usually arrives as a list in Spanish; treat
+each item as a separate, verifiable fix.

The advantage of the proposed strategy lies in expressing framework rigidity, which is inherently global, as a set of local properties. Also, we show that a framework's normalized rigidity eigenvalue degrades as the graph's diameter increases. Thus, the rigidity eigenvalue associated to each subframework arise naturally as a local rigidity metric. A decentralized subframework-based controller for maintaining rigidity using only range measurements is developed, which is also aimed to minimize the network's communication load.

But, while successfully applied in several areas, the concept lacks of a general and precise notion. Facts like the hierarchical structure and heterogeneity of complex networks make it difficult to unify the idea of community and its evaluation. The global functional known as modularity is probably the most used technique in this area. Nevertheless, its limits have been deeply studied. Local techniques as the ones by Lancichinetti et al. and Palla et al. arose as an answer to the resolution limit and degeneracies that modularity has. Here we start from the algorithm by Lancichinetti et al. and propose a unique growth process for a fitness function that, while being local, finds a community partition that covers the whole network, updating the scale parameter dynamically. We test the quality of our results by using a set of benchmarks of heterogeneous graphs. We discuss alternative measures for evaluating the community structure and, in the light of them, infer possible explanations for the better performance of local methods compared to global ones in these cases.}

The global functional known as modularity is probably the most used technique in this area. Nevertheless, its limits have been deeply studied. Local techniques as the ones by Lancichinetti et al. and Palla et al. arose as an answer to the resolution limit and degeneracies that modularity has. Here we start from the algorithm by Lancichinetti et al. and propose a unique growth process for a fitness function that, while being local, finds a community partition that covers the whole network, updating the scale parameter dynamically. We test the quality of our results by using a set of benchmarks of heterogeneous graphs. We discuss alternative measures for evaluating the community structure and, in the light of them, infer possible explanations for the better performance of local methods compared to global ones in these cases.},

We aim at establishing the role of such proximity in the emergence of a nested pattern of contacts. We conclude that although phylogenetic proximity is compatible with nestedness it can not be claimed to determine it. We find that nestedness can instead be attributed to a general rule by which species tend to behave as generalists holding contacts with counterparts that already have a large number of contacts. A nested ecosystem generated by this rule, shows high phylogenetic diversity. This is to say, the counterparts of species having similar degrees are not phylogenetic neighbours.}
