📝 WalkthroughWalkthroughThis change adds entitlement and subscription infrastructure, plan and entitlement APIs, entitlement-version headers, entitlement-aware feature states, asynchronous JWT plan hints, A/B variant schema declarations, and migration away from the stored user plan field. ChangesEntitlements, plans, and plan-claim flow
Estimated code review effort: 5 (Critical) | ~110 minutes Merge Risk: 🟡 Moderate · up to This change introduces paid-plan enforcement and entitlement reporting, but unresolved configuration and cache-consistency issues could grant incorrect access or retain access after entitlement changes. The public API documentation also does not fully describe the new entitlement contract. Resolve these issues before merge. Sequence Diagram(s)sequenceDiagram

Validate subscription coverage before unsetting users.plan.
update_many removes plan from every matching user. SubscriptionRepository.find_by_user supplies EntitlementService._compute; when it returns None, _compute sets plan = Plan.FREE. If a paid legacy plan is not represented by a subscription, this migration can downgrade the user. Query the left join on user_id and abort or backfill before the update.

Check entitlements before plan-gated actions.
FeatureFlagService.require() checks rollout state only. The catalog marks geo_targeting, custom_meta_tags, expired_fallback, and link_scheduling as unavailable to the Free plan, but their routes call only require(). Require Entitled and check entitlements.has(key) before each plan-gated action. Apply within_limit() where a numeric limit also applies.

Include a revision in the transition compare-and-set filter.
The asserted filter uses only user_id and status. Two workers can read the same ACTIVE document and both update current_period_end while keeping status ACTIVE. Both writes then match, and the later write overwrites the earlier accepted renewal.
Match a persisted revision, or the prior updated_at value, and update it atomically. Add a concurrent same-status renewal case.

…itlements One catalog declares each feature's rollout flag and per-plan defaults, and two evaluators read it: the flag service for deployment rollout and the new resolver for what a principal holds. Plan state is a status machine on the subscriptions document, versioned per owner in Redis and invalidated inside every repository write. Replaces users.plan, the TIER rollout and CurrentUser.tier.

What
The backend core of paid plans.
services/features/catalog.py) declares every gated capability and limit once: its rollout flag document, its per-plan defaults (anonymous, free, pro, selfhost), and its lapse or over-limit policy. Retiring a rollout isrollout=None, never deleting the entry.services/entitlements/) answers "what does this owner hold": plan defaults with overrides on top, cached per owner in Redis asent:{user_id}with a version.subscriptions(one per user, status state machine: active, past_due, cancel_at_period_end, grace, lapsed),entitlement_overrides(unique per user and key, with kind, reason, granted_by, expires_at),entitlement_events(append-only audit). The version bump, the audit event and the cache delete happen inside the repository write. A write that changes nothing writes no event and bumps nothing.Entitledrequest dependency resolves once per request and hands routes the map.states_forjoins flag and entitlement: flag off is hidden, on and entitled is enabled, on and not entitled is locked.GET /api/v1/me/entitlementsreturns version, plan block, feature states, limits with live used counts, and over_limit./me/featuresstays as the features-only alias.GET /api/v1/plansis the public projection of the catalog plus display prices from config.X-Entitlements-Version.planclaim (a hint for the client and the last fallback when both stores are down, never authority).RolloutType.TIER,FeatureFlagDoc.tier,CurrentUser.tier,UserPlan,users.planand theplanfield on the profile response.scripts/drop_users_plan.pyunsets the stored fields.Why
Every LOCKED upsell, every limit counter and the whole billing ticket need one answer to "what should this request do for whoever owns it". The redirect path asks that with no token in hand, so the resolver works from an owner id, and plan changes have to land within one request rather than one TTL, so the cache is versioned and invalidated by the write itself.
