Visitors see frequencies, banks, nets, ISS passes and the log without logging in; every
write stays owner-only (actions check the owner, hooks refuse non-GET). The public payload
drops reminder switches, log notes and inactive nets, and the page no longer shows the
observer coordinates (only "Gouda"). Dutch/English toggle (?lang, cookie, Accept-Language,
NL fallback). Larger fonts, high-contrast labels and 44px+ controls for phones and tablets;
radio listed as public (no lock) and in the sitemap; banks CSV public.
Owner-only tracker for learning the Cargill Bioindustrial plant in Gouda:
schema plant (entries, links with confidence, pending refs), plant.apply_entries
bulk import, overview with clusters and flow diagram, kind tabs, glossary,
questions, detail pages and owner inline editing. Docs in docs/plant-tracker.md.
Schema math (parts, chapters, sections, activity), seeded with all 100 chapters
(Ch 0-94, appendix A-E), 647 sections, PDF pages, exercise counts and approximate
prereqs. Triggers stamp started_at/completed_at and log status/exercise/note/section
changes; math.apply_progress(jsonb) applies the JSON format bots send. Private by
default via MATH_PRIVATE in #lib/math (owner-only prefix + lock in every tracker list).
Overall + per-part progress, current chapter, prereq hints, quick status buttons,
exercises stepper, notes, optional section ticks, activity log, dependency chart.
Deploy preflight checks the math schema (4 tables, 100 chapters).
dataholders schema (orgs + identity) with migration and personal_app grants,
idempotent CSV import (upsert on name+login, never wipes, keeps site edits and
ticks), owner-only /trackers/data-holders with search, filters, pagination,
inline edit/add and a moving checklist per identifier
- scripts/house-scrape.ts: polite nightly scrape (honest UA, 6-10 s apart, stops a source on 403/challenge), ingest + price history + removals, ntfy alerts on a separate topic (max 5 + summary, first run seeds)
- address_key + duplicate_of: copies on another source link to one listing, manual wins
- /projects/house-tracker -> /trackers/houses (308), owner only (404 otherwise); filters for min m2, rooms, source, Gouda region default; notes, add-by-hand form, total rent, also-on links
- scripts/house-db.sh: run the house-listing CLI as the limited house_cli role
- deploy/systemd/house-scrape.{service,timer}
