ArcaQ feature
§1 — What ArcaQ tracks for you
Six dimensions of habit intelligence — all computed on-premise.
Daily / Weekly / Monthly frequencies
Define habits at any cadence. ArcaQ aggregates streaks and completion rates.
Activity heatmap
A GitHub-style heatmap renders your last 90 days — every cell is a real triple in the graph.
Progress bars & streaks
Visual bars show weekly and monthly completion. Streaks are versioned graph assertions.
Categories & facets
Categorise habits and filter the graph view to see domain investment over time.
Sovereign storage
All data stored in Apache Jena Fuseki on-premise. No habit data ever leaves your infrastructure.
Linked knowledge
Tag each habit to related notes, projects or entities and see mastery connections.
§2 — Frequency baseline table
Default cadences shipped out-of-the-box. Customisable via OLM.
| Daily | Weekly | Monthly |
|---|---|---|
| Journal entry, meditation, exercise | Deep review, skill practice, team sync | Knowledge audit, goal review, retrospective |
§3 — RDF data model
Every habit event becomes a named triple in <arcaq:habits/>.
§4 — 90-day activity heatmap (demo)
Each cell = at least one completed habit that day — stored as an RDF assertion.
§5 — Nightly batch processing for all collaborators
An Airflow DAG (habits_daily_processor) runs every night at 01:00 UTC and automatically processes every collaborator's habits — no manual intervention required.
All-user discovery
SPARQL query on HABITS_GRAPH discovers every user who owns at least one habit — new collaborators are picked up automatically on their first day.
Streak computation
Current streak and longest streak are recalculated for daily, weekly and monthly habits and written back as arcaq:currentStreak / arcaq:longestStreak RDF properties.
Missed-day marking
Any habit without a log for the elapsed period (yesterday / last week / last month) receives an automatic doneBool=false entry so the heatmap shows real gaps, never blank cells.
Team Pulse digest
Aggregate counts (total habits, top streak, active habits) are pushed as arcaq:HabitDigest events to BRAIN_EVENTS_GRAPH — visible in Team Pulse without exposing individual habit details.
