 # MSRG website
 
-[Live website](https://msrg.github.io/) · [Repository](https://github.com/MSRG/msrg.github.io)
+Live website: https://msrg.github.io/
 
-Members propose changes through **pull requests (PRs)**. A maintainer reviews
-and merges them into `main`, which automatically publishes the website.
+Once polished, we plan to make the site available at `www.msrg.org` and
+`msrg.utoronto.ca` while keeping it hosted on GitHub Pages.
+
+Members propose changes through **pull requests (PRs)**. Thomas reviews and merges
+them into `main`, triggering the website's build and deployment.
+
+Ask Thomas (`ttrenty`) on Discord for collaborator access to create branches here,
+or fork the repository and submit a PR from your fork.
 
 ## Setup
 
-Install [Pixi](https://pixi.sh/latest/installation/) and Git. Pixi installs the
-pinned Hugo extended and Python versions automatically on Windows, macOS
-(Intel/Apple Silicon), and Linux (x86-64/ARM64). If you do not have write access,
-fork the repository on GitHub and use your fork's clone URL below.
+Install [Pixi](https://pixi.sh/latest/installation/) and Git.
+
+Pixi installs the project's pinned Hugo and Python dependencies on first run.
+
+If using a fork, replace the clone URL below with your fork's URL.
 
 ```sh
 git clone https://github.com/MSRG/msrg.github.io.git
 cd msrg.github.io
-git switch -c update-my-profile
-pixi run editor
+git switch -c <your-name>/<change-type>/<short-description> # example: ttrenty/fix/homepage-add-news
 ```
 
-Open **http://127.0.0.1:1314** to edit. The tool starts the local website too;
-use its preview link to view your changes. **Ctrl+C** stops both servers.
-
 | Command | Purpose |
 | --- | --- |
-| `pixi run serve` | Preview the website. |
-| `pixi run editor` | Open the website editor and start its local preview. |
-| `pixi run check` | Run tests, build, and check links. |
+| `pixi run serve` | Preview the website at the URL printed in the terminal. |
+| `pixi run editor` | Start the website editor and its local preview. |
+| `pixi run check` | Run tests, build, and check internal links. |
 | `pixi run build` | Build the website into `public/`. |
 
-The environment stays in `.pixi/`; commit `pixi.toml` and `pixi.lock`, not `.pixi/`.
-
-Tests, builds, and link checks use [Pixi's task cache](https://pixi.prefix.dev/latest/workspace/advanced_tasks/#caching)
-to skip unchanged work. Source or dependency changes invalidate it; missing or
-modified `public/` files trigger a rebuild. Builds also refresh across day
-changes for automatic alumni transitions. To force a fresh check, run
-`pixi run clean-cache`, then `pixi run check`. Preview and editor always start.

+- **Dawn (Mengli) Duan:** confirm current degree and completion details.
+- **Jacob, Krit, and Dawn:** clarify whether the recent welcome refers to a
+  new group affiliation or degree programme before changing existing start dates.
+  Luke's September 2026 start is already confirmed.
+- **Diego Romero and Said Carbot Cruz Trejo:** confirm group start dates and
+  whether they belong under Visiting Researchers. Their undergraduate roles
+  are sourced; home institutions alone do not establish a visiting appointment.
+- **Fei Pan:** confirm graduation and completion date. Alumni placement follows
+  the maintainer's former-student correction; no completion date is established.
+
+Keep unknown dates empty. An expected graduation date does not establish that
+someone has graduated. Alumni still need member-confirmed affiliation dates
+and missing profile links.
+
+### Alumni public-source review (2026-09-09)
+
+- Non-UofT addresses were removed during this earlier review. Members may now
+  provide a university or work address from any domain. Leave unknown addresses
+  empty rather than guessing replacements.
+
+- Added verified public profile links and seven sourced end years to the member
+  records. Date-source URLs are comments alongside the data; no new start dates
+  were collected. Public pages continue to show only end years.
+- **Alex Cheung, Chen Chen, Chunyang Ye, Guoli Li, Jian Li, Lixia Chen,
+  Mingwen Chen, Reza Sherafat Kazemzadeh, and Songlin Hu:** LinkedIn identity
+  matches remain uncertain. Do not attach a same-name result without matching
+  the MSRG affiliation or research history.
+- Remaining blank end dates need confirmation. Several TUM alumni biographies
+  still describe ongoing doctoral studies, so their wording cannot establish
+  completion dates. A later job, publication date, or degree at another
+  institution does not establish when someone left MSRG.
+- **Anton Sugolov:** his later Toronto master's degree does not establish the
+  end of his earlier MSRG undergraduate affiliation. Keep that date unknown.
+
+LinkedIn sign-in only returns the consenting member's own basic identity; it
+does not grant alumni-search or education-history access. This review used
+public sources without signing in or interacting with anyone's account.
+
+## Missing portraits
+
+Jenny Moore needs a portrait and personal profile links. Her undergraduate
+internship (May 2025–April 2026) and alumni status are confirmed; the supplied
+LinkedIn link points to MSRG's company page rather than her member profile.
+
+Nairui Tian, Amir Koutahi, Jiakai Wei, Maxuan Wang, Rev Liu, Chenkai Zhang, and Said Carbot
+Cruz Trejo still need verified photos. Alumni also have missing portraits.
+
+Amir's homepage has no portrait. No reliable photo was found for Jiakai,
+Maxuan, or Rev. LinkedIn blocked retrieval for Chenkai and Said; Said's other
+public profiles show default avatars. Keep the initials fallback until a
+verified or member-supplied portrait is available; do not substitute banners,
+identicons, or other people's photos.
+
+## Research topics to confirm
+
+- **Shiquan Zhang:** current emphasis on zero-knowledge proofs and quantum work.
+- **Yunhao Mao:** whether blockchain remains a current focus.
+- **Dawn (Mengli) Duan and Ben Cheng:** current MSRG research assignments and
+  specialties retained from earlier sources.
+- **Jiakai Wei, Rev Liu, Yifeng (Jason) He, Luke (Zixin) Li, and Maxuan Wang:**
+  specific group research topics remain unconfirmed.
+- **Diego Romero and Said Carbot Cruz Trejo:** confirm MSRG research themes;
+  their self-described interests do not establish a group project assignment.
+
+## Missing archives and bibliography
+
+- Recover verified download locations for `MW16.rar`, `middleare 20008.zip`
+  (legacy spelling), `p2ptopss_workload_2009.tgz`, and
+  `DatasetOfResourceDiscovery.zip`. Keep the site's unavailable-archive notices
+  and contact links until the files are recovered.
+- Obtain an authoritative group BibTeX/database export to check bibliography
+  completeness. The current archive contains the public legacy list and a
+  selection of newer papers. Preserve existing URLs when replacing preprints
+  with published versions.
+
+## Website verification and administration
+
+- Complete physical iOS/Android and manual accessibility checks, including
+  keyboard, screen readers, browser zoom, and portrait/landscape layouts.
+- Before any custom-domain cutover, inventory historical URLs and dataset
+  paths, configure Pages/DNS, update `baseURL`, and verify redirects. The existing
+  MSRG domain remains separate from the GitHub Pages deployment.

+# Thomas's personal site
+
+This is a standalone site: edit `index.html`, `assets/style.css`, and
+`assets/scene.js` directly. Hugo copies it to `/~thomas-trenty/` without templates
+or an extra build step. The photo is shared with Thomas's member card.
+
+The decorative scene uses a locally bundled Three.js 0.186.0 (MIT; license in
+`assets/vendor/THREE-LICENSE.txt`). It falls back to an SVG without JavaScript or
+WebGL, respects reduced motion, and stops animating when offscreen or hidden.
+
+To update the vendor bundle, install a pinned Three.js release and esbuild in a
+temporary folder, then bundle Three's `build/three.module.js` with
+`--bundle --minify --format=esm --legal-comments=inline` into
+`assets/vendor/three.js`. Copy that release's license too. None of this is needed
+to edit or publish the page normally.
