github.com/luxfi/coronad existed only as loose files: no .git, no history, no
remote. Invisible to any sweep that looks for a .git directory, and an rm -rf
would have destroyed it unrecoverably.
Includes two dependency repairs.
1. It did not build: "unknown revision v1.16.98" — the v1.16.x line was DELETED
from github.com/luxfi/geth. The requirement is baked into published modules
(crypto/constants/warp pin the dead tag, some also `exclude` the
alternative), so requiring crypto v1.20.2 / constants v1.6.2 / warp v1.24.1
is what escapes it.
2. Dropped two replace directives pointing at absolute paths on one disk:
replace github.com/luxfi/corona => /Users/z/work/lux/corona
replace github.com/luxfi/warp => /Users/z/work/lux/warp
Those would have made this module resolvable ONLY on this machine — CI or
any other checkout could never build it. They were also unnecessary: the
published versions the `require` lines already name (corona v0.10.4) build
and test clean without them.
Verified: go build ./... exits 0, go test ./... 1 ok / 0 fail.
The compiled coronad binary is ignored rather than committed.
NOTE: no remote — luxfi/coronad does not exist on GitHub. Still one copy.
