404oopsandClaude Opus 5.5 ad87892cd2 fix(metering): reserve AI credit only when it fits, in one step
`reserveAiCredits` checked the balance and then took an unconditional
hold, so concurrent requests could all pass the check before any hold
was visible; two 16.2M µ¢ holds were admitted against a 20M µ¢ balance.

The hold store now takes a hold only if it fits beside the live holds,
in one Lua script on the actor's hold key. A per-user version, bumped
when usage is recorded and when a hold is released, lets the script
refuse a balance read that a settlement has since overtaken; the
service reads the balance again and retries, and skips the version
check on its last attempt rather than refuse an account whose balance
keeps moving. Both keys share the actor's hash tag, so the script runs
on Redis Cluster. The balance read for this check reads purchased
credit consistently.

`reserveCreditsIfAffordable` carries this through the service, and the
AI facade calls it once with the cost factor applied. `reserveCredits`
keeps its unconditional semantics. When the cache is unreachable, the
balance alone decides and nothing is held, as before.

Getting Started

💻 Local Development

git clone https://github.com/HeyPuter/puter
cd puter
npm install
npm start

To run this checkout with Docker, follow Building from source. Create a local docker-compose.override.yml to select the local build; keeping these settings out of docker-compose.yml avoids conflicts when pulling updates and keeps local configuration out of pull requests.
