From c1b1ff7c961a2ce71049a6b3af684c5e2eb71a78 Mon Sep 17 00:00:00 2001
From: Esteban Carisimo <32495768+estcarisimo@users.noreply.github.com>
Date: Mon, 28 Sep 2026 19:13:47 -0500
Subject: [PATCH 1/5] Add publication topics, AGENTS.md, and American English;
 drop the contact e-mail

Publication topics (as on estcarisimo.github.io, but trilingual):
- New _data/publication_topics.yml with 18 topics (complex networks, k-core
  decomposition, visualization, community detection, graph theory, Internet
  measurement, Internet topology, IXPs, Latin America, traffic & latency,
  routing & protocols, IETF standards, wireless & multi-robot networks,
  media & opinion, human mobility & behavior, biological & physical systems,
  optical networks & security, engineering education), labels in ES/EN/FR.
- 87 of 89 entries in conexdat.bib tagged with `topics = {...}`; the two
  untagged ones are 1990s instrumentation papers that fit no topic.
- The filter bar gets a labeled Topics row next to the People row; topic,
  person and free-text filters combine, and deep links like
  /publications/#topic=latam&q=Carisimo work. Every entry shows its topic
  chips; on research-area pages they link to the filtered publications page
  in the current language.
- Selected chips now meet contrast (navy/white in light mode, celeste/deep
  navy in dark mode; the old white-on-celeste was 2.4:1).

Contact: no e-mail anywhere (group decision). The contact page points to the
director and the CoNexDat GitHub organization; the Scholar link, which is not
a contact channel, is gone. The dead electronica.fi.uba.ar subdomain (no DNS)
is replaced by the department page on fi.uba.ar, and faculty links use HTTPS.

Conventions:
- AGENTS.md (with CLAUDE.md including it), following the other CoNexDat
  repositories: layout, Ruby 3.3 commands, American English, three-language
  lock-step, no e-mail, no links into cnet.fi.uba.ar, the polyglot and
  inline-script pitfalls, and the PR workflow.
- American English across English content, comments and names (modeling,
  behavior, visualize, analyze, utilization, toward, gray, normalize, ...).
  Paper titles and proper names are kept as published.
- PR template and CONTRIBUTING gain the language, e-mail and topics rules.
- Repository docs (AGENTS, CLAUDE, CONTRIBUTING, CODE_OF_CONDUCT, SECURITY)
  and _scripts/ are excluded from the build; they were being published at
  the site root.
- Dependabot ignores jekyll-sass-converter 3.x (dart-sass breaks the theme).
- CI now also checks topic markup, the absence of mailto: links, and that
  repository docs are not published.

+# 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/

+  highlights.yml            home-page project cards
+  publication_topics.yml    publication topics (labels), trilingual
+  theses.yml, navigation.yml, ui-text.yml

+```
+
+## 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). 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.

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.

At a difference with most studies of opinion on social media, we do not choose the topics a priori, they naturally emerge from the community structure of the semantic network instead.

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 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.}

Subject: [PATCH 2/5] Publications filter: address review findings

- Leave plain anchors alone: a hash without topic= or q= (e.g. an entry
  anchor like #AHDBV2005) no longer resets the filters and strips the hash.
- Malformed percent-escapes in the hash (#q=100%) no longer throw; the raw
  text is used as the query.
- Modifier and middle clicks on topic chips fall through to the browser, so a
  topic can be opened in a new tab.
- Topic and people chips expose their state with aria-pressed.
- Clearing the filters keeps any query string in the URL.
- normalize_venues.py docstring: "Homogenize".

Subject: [PATCH 4/5] Publications filter: topic chips in the bar are real
 buttons

The bar's topic chips were links with role="button", which Space does not
activate. They are now <button type="button"> elements with aria-pressed;
the chips on each entry stay links so they also work from research-area
pages. Deep links to an unknown topic (#topic=nonexistent) are ignored
instead of hiding every entry.

Subject: [PATCH 5/5] Validate topic ids exactly; check them in CI; document
 untagged papers

- publications.js: a deep-linked topic is kept only if it is exactly one of
  the known ids from the bar (a quote in the hash could previously pass the
  check and hide every entry).
- CI: new step fails the build when a `topics` field in conexdat.bib uses an
  id missing from _data/publication_topics.yml.
- AGENTS.md: the two 1990s instrumentation papers are untagged on purpose.
