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).
Vault files stay the source of truth (bind-mounted read-write at /notes):
atomic writes chowned to the vault owner, hash-checked saves (409 on a
newer file), deletes to .trash. notes.* is a full-text/link index kept
current by a recursive watcher plus a 60s rescan; live updates over the
owner-only /ws/notes channel (paths and hashes only). Wikilinks, embeds,
backlinks, tags, callouts, image paste. Owner-only everywhere (404).
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
TrackerIcon + #lib/tracker-icons: one gradient rounded tile and a few stroke paths per
tracker (tasks, money, books, cars, music, health, groceries, houses, energy, games, skins,
pets, lists), distinct colours, readable in light and dark. No icon library. Test checks
every tracker has a unique tile and tasks/money/books stay first.
