Dares loop

Maintained reference for the dares feature: a couple sends each other challenges, each state change notifies the other partner, and the pair keeps a shared count of what they have finished together.

The asynchronous shape is the point. Every transition below is a push notification to whichever partner is not holding the app.

Actor rules are enforced server-side, not by hiding buttons:

Transition	Who	Legal from
accept / decline	recipient	pending
submit	recipient	active
complete	sender	active, submitted
cancel	sender	pending, active, submitted

The recipient performs the dare, so the recipient reports it done (submitted) and the sender confirms (completed). An illegal transition returns 409 invalid_transition; acting on someone else's dare returns 403 not_permitted; a dare outside your couple returns 404, never a hint that it exists.

Entitlement

Premium is couple-shared — either partner's subscription unlocks both, matching the answers domain.

Tier	Can do
Anyone, always	Receive, accept, decline, submit, complete, cancel
Free sender	Free packs, FREE_WEEKLY_SEND_LIMIT sends per rolling 7 days
Premium	All packs, unlimited sends, custom dares

Receiving is never gated. A paywall between a partner and the dare they were just notified about would break the loop the feature exists to create. The quota is counted per sender over a rolling window, and counts every send — cancelling does not refund it.

Content safety

dare_packs and dares carry content_status (unreviewed / allowed / archived), matching the legacy catalogue contract. The catalogue, the pack detail endpoint, and the send path each independently require allowed, so a stale client cannot send unreviewed content. New content defaults to unreviewed and is therefore invisible until an administrator reviews it.

Push copy is deliberately generic — "Your partner sent you a dare", never the dare text. Store compliance forbids question, dare, response, or message text in a notification preview, and dares.integration.test.ts asserts no payload leaks it.

History durability

sent_dares snapshots dare_text_snapshot and dare_intensity_snapshot at send time. Editing, archiving, or deleting a catalogue dare never rewrites what a couple was actually dared. This also fixes a latent defect: dare_id is ON DELETE SET NULL, and the old sent_dares_dare_or_custom_check made deleting any dare that had been sent fail with a check violation.

Notifications

queue_dare_operations (trigger on sent_dares) writes one operations_outbox row per transition with dedupe key dare:<id>:<event>:<recipient>, gated on notification_preferences.dares_enabled. Delivery, retry, and Expo ticket handling are the existing worker's job — see apps/api/src/domains/operations/README.md.

expired notifies both partners; every other transition notifies the one partner who did not cause it.

Expiry

The worker's produce pass expires any dare whose expires_at has passed while still pending, active, or submitted, reported as daresExpired in ProducerSummary. Pending is included deliberately: an invitation the recipient never opened would otherwise stay open forever.

Durations offered to the client are fixed presets (1, 6, 12, 24, 72, 168 hours, or none) and validated server-side.

HTTP contract

Method	Path	Notes
GET	/v1/dares/packs	Catalogue plus the caller's entitlement
GET	/v1/dares/packs/:packId/dares	402 when the pack is premium and the couple is not
GET	/v1/dares?filter=active|history	Couple-scoped; direction is relative to the caller
GET	/v1/dares/stats	Shared scoreboard
GET	/v1/dares/durations	Preset list the send sheet renders
POST	/v1/dares	dare_id or custom_dare_text, never both
POST	/v1/dares/:dareId/respond	{ action: "accept" | "decline" }
POST	/v1/dares/:dareId/submit	Recipient reports done
POST	/v1/dares/:dareId/complete	Sender confirms
POST	/v1/dares/:dareId/cancel	Sender withdraws

The actor always comes from the bearer identity; ownership fields in a request body are rejected.

Mobile

Reached from the home screen's DaresTile, which badges pending incoming dares. The screen has Active / Send / History tabs, polls on a 5s interval (there is no realtime channel), and opens the paywall both proactively and in reaction to a 402 — a client whose entitlement went stale still lands on the paywall rather than an error.

Tests

• apps/api/test/dares.integration.test.ts — real PostgreSQL: entitlement, quota, transitions, couple isolation, notification fan-out, no-text-in-push, snapshot durability
• apps/api/test/dares.routes.test.ts — HTTP contract and error mapping
• apps/mobile/src/__tests__/hooks/useDares.test.ts — loading, actions, paywall routing

Not in this version

Per-dare chat. dare_messages exists and is wired into the schema, but a second inbox split from the main match chat was cut in favour of status transitions plus the sender's note. Photo proof, random-dare, and streaks remain unbuilt.
