Phased Implementation & Rollout Checklist

• Approve the Master PRD and resolve all highlighted assumptions.
• Record the confirmed weekly recurring-generation contract: Free 1, Plus trial 1 total, Plus 2, Pro 5.
• Confirm 45 Free Explore minutes/week and one-week rollover cap.
• Record the confirmed Free one-time reset of 3 credits per 3 days; confirm paid monthly and file weekly rollover caps.
• Approve standard prices, discount reference price/duration, trial products, countries, and renewal terms.
• Approve grandfather cohort, plan, start/end, permanent-access policy, and exclusions.
• Approve nudge frequency caps and copy ownership.

Exit: signed monetization ADR/product contract.

• Merge/rebase backend billing, iOS billing, and admin grant branches onto active integration branches.
• Apply billing migrations in staging/dev through normal deployment, not hand-copy only.
• Set separate RevenueCat webhook secrets and keys for dev/prod.
• Verify bundle/build configurations cannot ship a dev API base URL to App Store.
• Make new billing access canonical and inventory every legacy tier consumer.
• Upload existing Beta build to TestFlight or cut a fresh build after branch integration.

Exit: all three apps build/deploy from reproducible branches and environments.

• Finalize products, service levels, localizations, pricing, 3-day trial, rescue products/offers, and win-back plan.
• Import products to RevenueCat; attach Plus/Pro entitlements.
• Create standard, 50%, and 65% offerings and paywalls.
• Create placement mapping and eligibility-aware paywall rules.
• Verify one App Store subscription group, Pro/Plus service levels, product-change paths, and the chosen native/RevenueCat management surface.
• Enable webhook lifecycle and paywall UI events.
• Verify one sandbox purchase reaches dev backend and unlocks access.

Exit: store catalog and RevenueCat dashboard are production-review ready.

• Add access phase/trial fields, plan versions, usage accounts/ledgers, offer state, exposure records, and grandfather batches.
• Implement recurring, one-time, Explore-seconds, and file-upload meters with rollover.
• Add reserve/finalize/release flows and structured denial responses.
• Enforce generation, scheduling, files, transcript, remix, speed policy, soundscape catalogs, Pro sources/export, and Explore playback.
• Run usage in observe-only mode and reconcile against real activity.
• Add alerts, sweeper/reconciliation, and entitlement mismatch dashboards.

Exit: API clients cannot exceed any approved plan rule.

• Update models/copy to approved Free/Plus/Pro plan definitions and trial profile.
• Wire all full-page and sheet placements to live navigation, including ContentDetailView.
• Add transcript, speed, soundscape, Explore-time, and file-size gates.
• Implement offer-stage coordinator and one-exit-offer-per-presentation flow.
• Implement pending-action resume and deduplicate simultaneous denials.
• Implement trial reminder and the separate iOS Subscription Management IPRD: Plan & Billing status, change/manage, restore, pending changes, and post-sheet refresh.
• Add jump-notification surfaces with server exposure commits/frequency caps.
• Complete accessibility, localization, analytics, screenshot harness, and UI tests.

Exit: TestFlight build passes every tier/placement/offer state.

• Merge current single-user grant console.
• Add backend-enforced billing roles and remove dependence on only shared admin secret.
• Add cohort builder, dry-run, approval, batch apply, progress, export, and campaign revoke.
• Run the approved legacy cohort dry run and get product/support approval.
• Apply grants before enabling production gates; verify samples and audit totals.
• Prepare support playbooks for restore, trial, offer, grant, refund, and entitlement mismatch.

Exit: eligible old users have verified access and operators can explain/manage it.

• StoreKit local matrix for all products, trials, offers, renewals, expiries, refunds, upgrades, downgrades, crossgrades, cancellations, restores, and transfers.
• RevenueCat sandbox and webhook replay/out-of-order/idempotency tests.
• Backend concurrency, rollover boundary, timezone, and failure-release tests.
• iOS device/locale/accessibility/offline/delayed-activation tests.
• Internal TestFlight → staff cohort → 5% → 25% → 100% server-flag ramp.
• Keep per-capability kill switches and the ability to suppress every paywall placement remotely.
• Monitor activation latency, mismatch rate, crashes, refunds, conversion, nudge opt-outs, and support tickets.

Exit: stable full rollout with rollback path exercised.

• Do not A/B trial length, price, and paywall design simultaneously.
• Experiment first on standard paywall design/copy, then trial, then rescue eligibility/duration.
• Use RevenueCat Experiments/Targeting only with identified users and current offerings.
• Judge by realized LTV and refund/retention, not initial conversion alone.
• Review the 65% stage after enough traffic; remove it if it trains users to dismiss or harms trust.
