LocationContext (deferred) — NextAction-attached location predicate

[capo-the-ai-bot]

Parent: #181 (domain-modelling synthesis). Deferred — not v1. Likely Phase 3 (OS hooks territory).

Scope (when picked up)

LocationContext = world-state predicate over the user's current location. Attaches to NextAction. Gates visibility of the action in surfaces.

Examples:

• "Fix garage door" → NextAction "check door alignment" has LocationContext = at-home.
• "Pick up dry cleaning" → NextAction "pick up" has LocationContext = near-cleaners.

Dependencies

• Geofencing / OS hooks — needs platform integration (Phase 3 milestone — see milestone phases).
• Existing location_id on Todo and design epic [Design] Contextual & Geofenced Surfacing #46 (Contextual & Geofenced Surfacing) — coordinate.

Migration story

• Existing Tag(type='context') rows that are location-shaped ("@home", "@office") get converted to LocationContexts on the appropriate NextAction.

Out of scope (this issue)

• Domain modelling — done in Epic: Blockers + Contexts domain modelling (parent for v1 plumbing + deferred variants) #181, captured in conversation memory.
• Implementation planning — pick up when Phase 3 work begins.

Notes

Deferred from #181 v1. The OS-hook dependency makes this naturally a Phase 3 candidate.
