Closes the two findings left open from the pre-launch review.
Node redundancy (it was node reachability, not chain health)
RPC_ENDPOINTS accepts any number of daemons in preference order; PRIMARY /
FALLBACK still work and are appended. The list is deduplicated, which exposes
that the stock config pointed both at the SAME host — what looked like
redundancy was one node.
One logical call now walks every endpoint before failing, instead of needing
three consecutive failures to try exactly one alternate. Each node still has
to pass the chain-identity check before it may answer, so failover cannot
silently serve another chain's data. `failoverActive` is no longer a one-way
latch: the preferred node is re-tested every RPC_PREFERRED_RETRY_MS, so
recovery no longer requires a restart. healthCheck probes every node.
Graceful failure
Entries are refused while no node is reachable. A run is measured in blocks
and its entry block comes from the last successful poll, so a game admitted
during an outage was anchored to an already-past block and killed as a timeout
on the first recovered poll — the player lost a run, and in paid mode an
entry, to our infrastructure. The gate sits in _runAdmission, ahead of any
credit spend, and says so to the player.
Wallet: refused, not failed over
Two wallet-rpc processes over one wallet file can build transactions from the
same outputs and corrupt the cache. A standby wallet is a custody decision for
the operator, not something this code may take on its own — daemons are
read-only and interchangeable, wallets are neither. So a wallet outage
declines paid intake cleanly and leaves credits and free play working.
Auth limiter evicts instead of refusing
The bounded key map 429'd any NEW ip once full, turning a memory cap into a
DoS primitive: a distributed source could hold it at capacity and lock every
first-time caller out of Smirk login. It now reclaims expired entries and, if
still full, evicts the oldest live windows. Same memory ceiling, still a
working limiter.
129 suites / 1026 tests pass.
