1. 1. Project Setup

   Build Credit Trail, a simulator and operational view for application usage credits.
   Use Next.js and TypeScript for a small web workspace.
   Use Supabase Auth as the only login and Supabase for owned account records.
   Start with fictional usage units and simulated requests; do not accept real money.
   Create an account list, a request simulator and an account timeline.
   Tables:
   - credit_accounts(id, owner_id, display_name, unit_name)
   - credit_entries(id, account_id, request_key, entry_kind, units, reason, created_at)
   - request_reservations(id, account_id, request_key, units, state)
   Enforce ownership on the server and show reserved and available units separately.
   Do not build: billing, payment collection, external model calls, production migrations or enterprise permissions.
   Done when: an owner can create a fictional account and inspect a simulated request's credit history.

2. 2. Core Feature

   Implement reserve, settle and release transitions in Credit Trail.
   Give each simulated request a stable key and an explicit usage unit.
   Make repeated transitions return the original outcome without adding postings.
   Use database transactions for related reservation and ledger changes.
   Show corrections as new entries with a reason and reference.
   Add fictional success, failure, retry and cancellation examples to the simulator.
   Done when: each scenario has an explainable final balance and replaying a transition changes nothing.

3. 3. Landing Page

   Create a landing page for Credit Trail aimed at indie AI app developers.
   Explain the proposed request lifecycle and support-readable account timeline.
   Show a fictional request moving from reservation to success or release.
   Describe the prototype's scope and the production integration work still needed.
   Store pilot enquiries in a waitlist table using the existing database.
   Use one call to action: request an integration pilot.
   Done when: a developer understands the proposed workflow and can submit a pilot enquiry.

4. 4. Branding Package

   Use a design or image tool to create a branding package for Credit Trail.
   Design a simple wordmark and a symbol based on a readable sequence of ledger entries.
   Use neutral surfaces with mint, amber and muted red state accents.
   Give every state a text label so meaning does not depend on color.
   Include light and dark wordmarks and an application icon.
   Avoid bank, investment or guaranteed-return imagery.
   Done when: the exported assets work on the account timeline and at small icon sizes.
