# Future — ideas & improvements backlog

Non-blocking ideas: things that work today but could be better, plus feature ideas. Actual bugs
(broken/incorrect behavior) live in `ClaudeReport.md`, not here.

## QA

Improvement & feature ideas surfaced while QA-testing as a consumer (each works today — none are defects).

- **Consistent brand glyphs across game cards + waiting/notification surfaces.** _(Blocked: needs the
  generated G-set art — image generation is the user's step per `ClaudeBrandingReview.md`.)_ Game cards
  (Play hub), the WaitingForPartner screen, and notifications mix Material icons with brand art. A small
  custom glyph set (the C-heart-keyhole mark, paired/sealed card, daily card, capsule, date-card,
  quiet-hours moon) used consistently would strengthen identity. Generate the G-set, drop the assets in,
  then wire them in. *Prompted by:* Pass H branding review.

- **Notify the free partner when the couple gains premium.** When one partner subscribes, the other's app unlocks
  (couple-shared premium) but they get **no notification** — they only find out next time they open a gated feature. A
  `subscription_entitlement_changed` push ("You both have Premium now ✨") would close the loop. *Prompted by:* Pass E
  (R8): the type isn't implemented; couple-shared unlock is silent for the non-subscriber.
- **Minor proactive-notification gaps (low priority).** No push when a partner *joins* your active game
  (`partner_joined_game`) or *ends/abandons* one (`game_ended`/`game_abandoned`) — the other partner sees it
  in-session / on WaitingForPartner, so nothing's broken, just less proactive. *Prompted by:* Pass E (R8) inventory —
  these speculative types aren't implemented.

### Security hardening (defense-in-depth — not vulnerabilities; rules already hold)

- **Enforce App Check on Firestore (currently OFF).** Round 7 raw-API test: an authenticated request with **no App
  Check token** (raw Firestore REST) returned `200` for a member — so rules are the *sole* gate. Rules correctly deny
  non-members/cross-couple (all `403`), so this is not a live hole, but enabling App Check enforcement on Firestore
  would block non-app clients entirely (defense-in-depth). *Prompted by:* R7 D3 raw-API angle.
- **Tighten the `users/{uid}` update rule to a field allowlist.** The rule only blocks changing `hasPremium`; a user
  can write arbitrary *other* fields to their own doc (e.g. a cosmetic `plan`/junk). No gate reads those (premium gates
  on the server-only `users/{uid}/entitlements/premium` subcollection + `category.access`), so it grants nothing — but
  restricting updates to a known field set is cleaner. *Prompted by:* R7 D3 (`plan` field writable, unused by gating).

<!--
Completed (2026-06-25) and removed from the backlog:
- Inclusive sex/gender options in onboarding (Female/Male/Non-binary/Prefer not to say) + honest copy
  (Desire Sync is already gender-neutral, so no tailoring fallback was needed).
- Turn-aware Home "waiting to play" copy ("Your turn to play.").
- Partner-action/results pushes exempt from the weekly promotional rate-limit ceiling.
- Suppress the redundant results / "partner finished" push when the recipient is already on that
  game's screen (new ActiveGameSessionMonitor mirroring ActiveThreadMonitor).
- Friendlier paywall error state: retry-with-backoff, offline-aware message, Continue hidden until plans load.
- Wire iOS illustrations into Android empty states — already wired (history, invite, daily-question,
  together-empty, partner-activation all show their illustration).
- Rotating privacy messages on sign-up + forgot-password (login already had it).
