Calendar Commitment Guard

A scheduling guard that classifies each invitation and proposes accept, decline, delegate, or request agenda.

Authored HypothesisVerification and guardrailsMEDIUM confidenceIndie fit 9/10
Problem
Calendars accept meetings without judging context switching, preparation burden, or strategic value.
Why Jev
The core operation is a repeated typed decision over calendar and relationship state.
Architecture
Invite + calendar + user policy → decision probabilities → deterministic availability checks → suggestion.
Current alternative
Static scheduling rules or manual review.
Jev advantage
Semantic policy can run for every invitation without composing messages unless requested.
Unknowns
Sparse personal training signals and sensitive relationship context.
1–7 day MVP
Google Calendar read-only companion with a daily review feed.
Validation experiment
Compare suggestions with the user's actual decisions for 50 invitations.

Why this confidence: Clear indie MVP, with value depending on personalized accuracy.

This is an authored hypothesis derived from the research corpus. Nothing here demonstrates product demand, or that Jev performs well on this particular workload. Run the validation experiment before building past the MVP.

Limitations

  • Sparse personal training signals and sensitive relationship context.
  • This is a research hypothesis, not evidence of product demand or Jev performance in this workflow.

Supporting research

  • Probabilistic predicate + deterministic action PlausibleJev supplies fuzzy predicates while TypeScript, policies, and workflows execute constrained actions.
  • HA-Jev ObservedA Home Assistant custom integration exposing Jev evaluations as sensors and automation actions.
  • Routing, classification, verification, and workflow control are the dominant early mental models. PlausibleThose categories recur in the collected launch discussion and align with the documented output primitives.
  • Parallel decision matrix PlausibleOne state is evaluated against many named questions, replacing repeated prompt/parse cycles.
