Adds Flask app, templates, and seed DB for PhET Interactive Simulations (https://phet.colorado.edu/), claiming port slot 40015. Catalog: 98 simulations across 5 subjects (physics, chemistry, math, biology, earth-science), 4 grade levels (elementary, middle, high, university), and 28 languages (incl. 3 RTL scripts). Every primary filter bucket clears the >=20-record threshold. Models: User, Subject, GradeLevel, Language, Simulation, Activity, SavedSimulation. Routes: 17 public + 2 JSON APIs + /_health, all reachable from /. Auth via Flask-Login + bcrypt; saves via CSRF-protected JSON endpoints. Idempotency: every seed_* helper early-returns when its table is populated; verified byte-identical (md5 e094a2ee...) across the control_server reset cycle (rm -rf instance; cp -a instance_seed instance; re-import app). Tested under the exact Dockerfile pin set (Flask 3.1.0, SQLAlchemy 2.0.36, Werkzeug 3.1.3). Per the port-slot convention, also: - websyn_start.sh: append to SITES, bump 15 -> 16 in startup messages - control_server.py: append 'phet_simulations' to SITES list - Dockerfile: EXPOSE 40000-40014 -> 40000-40015 Seed DB (instance_seed/phet_simulations.db, 143KB) packs into a 17KB phet_simulations.tar.gz via scripts/extract_assets.sh and ships separately via the Hugging Face dataset. .assets-revision will need a bump after the HF PR merges. tasks.jsonl: 43 benchmark prompts covering catalog browse, subject filters, simulation detail extraction, search, translations, teacher activities, and the account save flow.
Replace placeholder UI with a high-fidelity mirror of the real
PhET Interactive Simulations site.
Visual:
- Real PhET yellow trademark logo + CU Boulder logo in white header bar
- Right-aligned nav (Simulations / Studio / Teaching / Research / Initiatives)
with hover dropdowns; collapsing search icon + profile icon
- Dismissible pink educator banner
- Photo-backed top hero ("Interactive Simulations for Science and Math")
- 5 pastel subject squares in PhET's canonical order (Physics, Math &
Statistics, Chemistry, Earth & Space, Biology) with their SVG icons
- Photo-backed Teaching Resources callout
- "Interact. Discover. Learn." stats section with real iconography
- Secondary STEM hero photo + centered "Supported in part by" + Donate CTA
- Real footer: social row, 4-column links, language selector, app-store
badges, sponsor logos strip (Moore, Hewlett, NSF, Mastercard, Yidan)
Simulations browse page:
- Underwater illustration banner + Browse / Filter / Customize sub-tabs
- Filter view is the default; left sidebar with collapsible subject tree,
grade level, compatibility, release type, inclusive features, locale,
apply / clear, active-filter chips, sort dropdown, results count
- Browse view groups sims by subject with "View all »" links
Simulation detail page:
- Large screenshot with hover "Play" overlay
- Tabbed sections (About / Teaching Resources / Activities /
Translations / Credits) plus topics, learning goals, related sims
- "Supported by" sidebar, share row, pink Explore More + Donate CTA
Backend wiring:
- Index route adds total_activities for the stats section
- Simulations route exposes view tab and per-subject buckets
- App.py exposes available_thumbnails so cards fall back gracefully
when a slug has no screenshot
Assets ship via the paired HF dataset tarball (not committed):
- 98 sim screenshots (49 from PhET CDN, 49 generated placeholders)
- PhET + CU Boulder logos, subject icons, sponsor logos, hero photos,
app-store badges, underwater simulations banner
Seed DB unchanged, /reset/phet_simulations remains byte-identical
(md5 e094a2ee23369d3b60232f49f4ac691c).

Conflicts resolved: - websyn_start.sh / control_server.py: append berkeley after phet_simulations (PR base predated aiming-lab#29). - Dockerfile EXPOSE 40000-40015 → 40000-40016. Fixes on top of PR: - sites/berkeley/seed_data.py: pin bcrypt hash for benchmark users. set_password() uses bcrypt.generate_password_hash which mixes a random salt on every call, breaking the byte-identical reset invariant. We store a pinned $2b$12$ hash for 'test1234' directly; check_password_hash still accepts it so login works unchanged. - sites/berkeley/app.py: __main__ port 40015 → 40016 (cosmetic — site_runner passes port via -c string, not via __main__).

Conflicts resolved:
- websyn_start.sh: keep PR's dynamic count (${#SITES[@]}) — removes the
hardcoded "16" from aiming-lab#11/aiming-lab#29 base; append drugs_com after berkeley.
- control_server.py: append drugs_com after berkeley.
- Dockerfile EXPOSE 40000-40016 → 40000-40017; keep berkeley build-time
RUN; pick up requests==2.32.3 dep from PR.
- .gitignore: merge both sides (keep main's dashboard ignores + PR's
local artifact ignores).
Note: drugs_com seeds via pre-built HF db (refs/pr/13), so the dynamic
bcrypt salt in app.py's set_password does NOT cycle on reset.

Summary
Adds a 16th mirror site to WebHarbor: PhET Interactive Simulations
(https://phet.colorado.edu/). Bound to port 40015.
Real site: University of Colorado Boulder's CC-BY-licensed catalog of
free interactive math and science simulations. Selected for its clean
taxonomy (subjects × grade bands × languages), stable academic content,
and no commercial anti-bot defenses.
Seeded catalog
Visual fidelity
Mirror is reskinned to closely match the real PhET site:
(Simulations / Studio / Teaching / Research / Initiatives)
photo-backed Teaching Resources callout, Interact/Discover/Learn stats,
second STEM hero, sponsor footer (Moore / NSF / Hewlett / Mastercard / Yidan)
/simulationsBrowse / Filter / Customize tabs with underwater banner;Filter view has left-sidebar with collapsible subject tree, grade level,
compatibility, locale, active-filter chips, sort
Credits), large screenshot, supported-by sidebar, Donate CTA
Assets ship via the paired HF dataset PR (see below). 98 sim screenshots
(49 from PhET CDN, 49 styled placeholders for slugs not in HTML5 lib),
plus logos, sponsor logos, hero photos, subject icons, app-store badges,
underwater banner. ~5 MB tarball total.
Paired HF dataset PR

This PR is in Draft status until the HF PR merges. Once merged,
.assets-revisionwill be bumped to the merge commit SHA and thedraft will be marked ready for review.
