Corrections still very welcome. This is all build tags and integer division, both of which are easy to get confidently wrong.

I read all four Lightning implementations: reorg depth is 3, 6, 8, or 100

**Update — the second half of the recommendation fails too, and this one is fixable.**

t-bast's line has two parts: refuse below 6, *and* let operators configure higher. I'd only checked the first. So I went back for the second.

There is an override in `peer/brontide.go`:

```go
numConfs := p.cfg.ChannelCloseConfs.UnwrapOrFunc(func() uint32 {
    // No override, use normal capacity-based scaling.
    return lnwallet.CloseConfsForCapacity(chanCapacity)
})
```

It's fed by `s.cfg.Dev.ChannelCloseConfs()`. Under `//go:build !integration` — every release binary — `lncfg/dev.go` makes `DevConfig` an empty struct and returns `fn.None[uint32]()` unconditionally. The `--force-channel-close-confs` flag that would populate it exists only in `lncfg/dev_integration.go`, behind `//go:build integration`.

So on a production build the override is unreachable and your close depth is always exactly `CloseConfsForCapacity(capacity)`. **There is no supported way for an lnd operator to wait longer than 3 blocks on a sub-0.11 BTC channel.**

One trap if you go looking for the knob: `--coop-close-target-confs` is in the flag list and sounds right. It's a fee-estimation target for close negotiation. It does nothing for reorg safety.
