Continues #1863. Three of the four commits are @Saarlandpower's and
@SaarMesh-Bot's, authorship unchanged. The fourth is mine and is
explained below.
## Why a rebase was needed
#1863 was stacked on #1824, and #1841 merged instead. Both carried the
same pathTrust base from different commits, which is why the two
conflicted while each reported MERGEABLE against master. Cherry-picking
#1863's own three commits onto master applied cleanly with no conflicts,
which confirms its actual work was always independent of that duplicated
base.
## The fourth commit, and a correction to something I got wrong
The three commits do not build on master:
```
cmd/ingestor/main.go:455:23: cfg.GetPathTrust undefined (type *Config has no field or method GetPathTrust)
```
**#1824 added the pathTrust config and helper to both
`cmd/server/config.go` and `cmd/ingestor/config.go`. #1841 carried only
the server half** — one of its own commits is titled "remove ingestor
side". I then closed#1824 as superseded by #1841, which is true for the
server side and wrong for the ingestor side. Master has no pathTrust
code in `cmd/ingestor/config.go` at all.
The fourth commit restores that half, unchanged from `beae2c1c`: the
`packetpath` import, the `PathTrust` field, the `PathTrustConfig` alias,
`GetPathTrust`, and `cmd/ingestor/config_test.go` verbatim (28 lines
covering the default, an explicit value, and a nil `*Config` receiver).
That code is @Bjorkan's and @SaarMesh-Bot's from #1824, not mine; I only
put it back.
## Verification
- All three original commits cherry-picked onto `b3a306b8` with **no
conflicts**
- `cmd/ingestor` builds, and its `PathTrust|Neighbor|Config` tests pass
- `cmd/server` `Neighbor|PathTrust|AnonReq|Edge` tests pass
## Interaction with #1929#1929 moves `DefaultMinHashBytesForMapping` from 2 to 1. With that in,
this PR's ingestor gate is a no-op by default and only takes effect when
an operator sets `minHashBytesForMapping` to 2 or 3, which is the opt-in
shape #1784 asks for. The two are complementary; merge order between
them does not matter.
@Saarlandpower @SaarMesh-Bot — your work, your credit. Say the word and
I will close this and hand the rebase back, or push it to the #1863
branch if you would rather that stayed the vehicle.
