Julien Voisin a08b0f4262 perf: enable uuid randomness pool and minor cleanups (#1652)
cmd/anubis: call uuid.EnableRandPool() at the top of main. The pool
batches crypto/rand reads internally, dramatically reducing per-call
syscall overhead for UUID generation. UUIDs are produced on every
issued challenge (NewV7, 3.7 times faster, down to zero allocation) and on
every challenge page render (NewString, 1.6 times faster, 1 fewer allocation).
The pool is non-cryptographic-key material, PoW challenge bytes and signing
keys still go directly to crypto/rand.

lib/anubis.go: three trivial optimizations in issueChallenge and
maybeReverseProxy, reducing the amount of allocations by 2%, which isn't much
but since the changes are trivial:

  - fmt.Sprintf("%x", randomData) -> hex.EncodeToString(randomData)
  - cache uuid.UUID.String() once instead of calling it three times
  - fmt.Sprintf("ogtags:allow:%s%s", ...) -> string concat

Julien Voisin 3dc962b301 perf(internal/gzip): pool *gzip.Writer per middleware instance (#1654)
gzip.NewWriterLevel allocates fresh deflate window and hash table
buffers (~1.18 MiB) on every request. This commit pools them in a closure-local
sync.Pool so each middleware instance reuses its writers.

The level is validated once at setup (NewWriterLevel against
io.Discard); pooled writers are reset to io.Discard on Put so the
pool doesn't pin response writers between requests.

Only call site is RenderIndex (lib/http.go), which serves the
challenge page, so this directly cuts the per-challenge allocation
footprint.

I benchmarked the change using the following benchmark,
put in the commit message instead of in a file since it's pretty much useless
outside of this particular change.

```
package internal

import (
	"io"
	"net/http"
	"net/http/httptest"
	"testing"
)

func BenchmarkGzipMiddleware(b *testing.B) {
	payload := make([]byte, 4096)
	for i := range payload {
		payload[i] = byte(i)
	}

	inner := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		w.Write(payload)
	})
	h := GzipMiddleware(1, inner)

	b.ReportAllocs()
	b.RunParallel(func(pb *testing.PB) {
		req := httptest.NewRequest(http.MethodGet, "/", nil)
		req.Header.Set("Accept-Encoding", "gzip")
		for pb.Next() {
			rec := httptest.NewRecorder()
			h.ServeHTTP(rec, req)
			io.Copy(io.Discard, rec.Body)
		}
	})
}
```

The results are pretty nice:

Benchmarks (Linux arm64, count=10, benchstat, vs origin/main):

  GzipMiddleware-8  sec/op     158.8µs ± 4%  ->   5.2µs ± 3%  -96.72% (p=0.000)
  GzipMiddleware-8  B/op       1180.6 KiB    ->   1.9 KiB     -99.84% (p=0.000)

Xe Iaso 926f3d1d0e fix: small security fixes (#1651)
This is based on private evaluation of a prerelease security product.
I cannot comment further other than I am impressed by its output.

This commit is a squash of several commits. The impactful commits
have details underneath markdown heading twos.

## fix(metrics): don't expose pprof by default

pprof[1] is the Go standard library profiling toolkit. It is invaluable
for diagnosing how Go programs perform in the wild. However it also is
able to expose secret data set with command line flags. This is not
ideal and should be mitigated by correctly configured firewall rules. We
don't live in a world where people correctly configure firewall rules,
so we have to fix things for people. Welcome to 2026.

Ref: AWOO-001

## fix(honeypot/naive): cap r9k delay to one second

Otherwise this can get unbounded, which can cause problems with lesser
HTTP proxies such as Apache.

Ref: AWOO-002

## fix(policy): mend an edge case with subrequest auth and query strings

This fixes an unlikely edge case where using subrequest auth and query
strings with path based filtering can cause reality to differ from
administrator intent. This effectively strips the query string from
subrequest auth checks. This deficiency should be fixed in the future.

Ref: AWOO-004

## fix(expressions): mend possible nil pointer deref edge case

If Anubis just started up, load averages may not be set in memory. This
can cause a nil pointer dereference which could fail requests with weird
errors until the async thread sets the load averages.

Ref: AWOO-005

## fix(lib): mend case where domainless redirects could allow cross-domain redirects

Ref: AWOO-009

## fix(expressions): validate randInt bounds before rand.IntN

Non-positive or platform-overflowing arguments to the CEL randInt
helper used to reach rand.IntN unchecked, surfacing a CEL evaluator
error during request processing when policies passed
attacker-influenced values (e.g. contentLength). Reject non-positive
bounds and detect int narrowing explicitly, returning a typed CEL
error in both cases.

Xe Iaso b57508afcd fix(honeypot/naive): apply robot9001 style delays (#1632)
Currently the honeypotting feature has no limits or delays anywhere and
uses that to feed an internal greylist of IP networks. This can cause
issues such as in #1613 where Claude's crawler seemed to pick up on it
and egress data at over one megabit per second until the administrator
noticed and blocked the address range.

This takes a different approach by inspiration of how the classic #xkcd
IRC bot Robot9000 works. The first time a given IPv4 /24 or IPv6 /48
visits a honepot page, Anubis sleeps for 1 millisecond. The second it
sleeps for two milliseconds. The third is four milliseconds and so on.
The goal of this is to make the scraping inherently self-limiting such
that the scrapers go off in their own corner where they won't really
hurt anyone.

Let's see if this works out according to keikaku.

Xe Iaso 276b537776 fix(policy): correctly wire subrequest mode through CEL/path checkers (#1630)
* fix(policy): correctly wire subrequest mode through CEL/path checkers

Previously Anubis only checked for the X-Original-Url when using
subrequest mode. This header is used by the example nginx config to pass
the request path through from the original client request to Anubis in
order to do path-based filtering.

According to facts and circumstances, Traefik hardcodes its own
headers[1]:

```text
httpdebug-1  | GET /.within.website/x/cmd/anubis/api/check
httpdebug-1  | X-Forwarded-Method: GET
httpdebug-1  | X-Forwarded-Proto: http
httpdebug-1  | X-Forwarded-Server: b9a5d299c929
httpdebug-1  | X-Forwarded-Port: 8080
httpdebug-1  | X-Forwarded-Uri: /
httpdebug-1  | X-Real-Ip: 172.18.0.1
httpdebug-1  | Accept-Encoding: gzip
httpdebug-1  | User-Agent: curl/8.20.0
httpdebug-1  | Accept: */*
httpdebug-1  | X-Forwarded-For: 172.18.0.1
httpdebug-1  | X-Forwarded-Host: localhost:8080
```

As a result, this means that path-based filtering did not work.

This commit fixes this issue by amending how path based checking logic
works:

* For CEL based checks, this pipes through the `subrequestMode` flag from
  main and alters the behaviour if either `X-Original-Url` or
  `X-Forwarded-Url` are found. These values are currently hardcoded for
  convenience but probably need to be made configurable in the policy
  file at a future date.
* For path-based checks, this uses the existing `subrequestMode` flag
  from main and adds `X-Forwarded-Url` to the list of headers it checks.

A smoke test was added to make sure that traefik in this mode continues
to work. Thank you https://github.com/flifloo for filing a detailed
issue with the relevant configuration fragments. Those configuration
fragments formed the core of this smoke test.

- Fix an obscure case where Anubis in subrequest mode could allow redirects to invalid domains with strange instructions.
- Fix `path_regex` and CEL `path` rules not matching when using Traefik `forwardAuth` middleware. Anubis now checks `X-Forwarded-Uri` (Traefik) in addition to `X-Original-URI` (nginx) when resolving the request path in subrequest mode ([#1628](https://github.com/TecharoHQ/anubis/issues/1628)).

### Debug routes
Anubis' metrics server supports [pprof](https://pkg.go.dev/runtime/pprof), the Go standard library tool for profiling Go applications. This is very useful for debugging how Anubis works in the wild with regards to CPU, multicore, and RAM usage. pprof is very powerful and can expose command line arguments as part of the debugging setup (inside Google, everything is done with command line flags).
Prior versions of Anubis exposed pprof endpoints on all TCP bindhosts by default. This means that machines with incorrectly configured firewalls can expose command line arguments to the public internet in the right conditions.
In order to enable pprof profiling endpoints on the Metrics server, set the `debug` flag under the `metrics` block:
```yaml
metrics:
bind: ":9090"
network: "tcp"
debug: true
```
To err on the side of caution, this defaults to disabled. If this defaults migration breaks your configuration, please let us know in a ticket.
### TLS
