Store an independent snapshot of the deposit outpoints selected for a
static loop-in. This keeps recovered swaps tied to the original funding
outputs even if the deposit records later reflect replacement or
confirmation changes.
Avoid recovering an empty database outpoint string as a synthetic
outpoint entry, and cover recovery of the stored snapshot separately
from the current deposit metadata.
Teach the liquidity manager to include persisted static loop-ins
in budget accounting, in-flight limits, and peer traffic backoff.
This adds the static fee model used for conservative accounting
and passes storage errors through the relevant planner helpers.
The daemon wiring now exposes static loop-ins to liquidity so the
manager can see the same ongoing swaps that the static-address
subsystem persists, while easy autoloop keeps working with the new
fallible traffic lookup path.
The Parameters struct describes the keys, expiry and pkScript that
define the static address script, so its natural home is the script
package. Moving it there lets staticutil drop its dependency on the
address package and lets callers reuse a single type alongside
script.StaticAddress and script.NewStaticAddress.
No behavior change.
Closes#1056
createHtlcTx always places the HTLC output at index 0 and the change
output (if any) at index 1. Previously, createHtlcSweepTx attempted to
dynamically find the HTLC index but then unconditionally read
TxOut[0].Value, ignoring the computed index.
Replace the dynamic search with a const htlcInputIndex=0 and a fail-fast
check that errors if the layout invariant is ever violated. Add a test
that verifies the sweep value is derived from the HTLC output, not the
change output.
In this commit we add a new function SelectDeposits
to the loop-in manager. It coin-selects deposits that
meet an arbitrary swap amount provided by the client.
We have to ensure that the server creates the correct
change outputs for the htlc- and sweepless sweep
transactions.
