The three settings of "Configuration surface" in SPEC.md that next did not read, for #112.
SWWAF_IPV6_GROUP_PREFIX (default 64, from 32 to 128): clientGroup becomes a method of the handler that reads it, so every place a client is grouped follows it: the rate and byte limits, bans, history, lookups, AbuseIPDB scores, the anomaly counters per client and client_group.
SWWAF_MAX_TRACKED_CLIENTS (default 20000, above zero): ratelimit.New takes the table size in place of the fixed maxClients; clients.json read at start keeps the most recently seen.
SWWAF_LOG_LEVEL (default info: debug, info, warn, error): requestlog.NewProcessLogger takes the level. Request lines go through requestlog.Write, not the logger, so nothing holds them back.
README.md documents each, and drops the first two from the fixed limits.
Not in the diff: after SWWAF_IPV6_GROUP_PREFIX changes, what was kept under an IPv6 client's old group (counts, history, GeoJS answer, AbuseIPDB score) is not used for its new one, while bans keep refusing their old netblocks, since the ban ledger already looks up every length it holds. No message is at debug yet, so debug writes what info does. Until the settings are read the logger is at error; the one message then is an invalid setting's error.
Judgement call: the range 32 to 128 is the one the issue gave as an example.

The three settings of "Configuration surface" in `SPEC.md` that `next` did not read, for https://git.eeqj.de/sneak/smallwebwaf/issues/112.
- `SWWAF_IPV6_GROUP_PREFIX` (default `64`, from 32 to 128): `clientGroup` becomes a method of the handler that reads it, so every place a client is grouped follows it: the rate and byte limits, bans, history, lookups, AbuseIPDB scores, the anomaly counters per client and `client_group`.
- `SWWAF_MAX_TRACKED_CLIENTS` (default `20000`, above zero): `ratelimit.New` takes the table size in place of the fixed `maxClients`; `clients.json` read at start keeps the most recently seen.
- `SWWAF_LOG_LEVEL` (default `info`: `debug`, `info`, `warn`, `error`): `requestlog.NewProcessLogger` takes the level. Request lines go through `requestlog.Write`, not the logger, so nothing holds them back.
- `README.md` documents each, and drops the first two from the fixed limits.

internal/smallwebwaf/smallwebwaf_test.go, TestLogLevelHoldsBackProcessLinesAndNoRequestLine with freeAddress: the test listens on a loopback port, closes it, and has smallwebwaf listen on it, so it fails whenever another process takes that port in between, the defect the review of #84 required removed. Acceptable: a test of the level that does not depend on a port staying free, with the judgement call about it gone from the commit and the PR body.
README.md, the opening paragraph of "Settings": "the effective settings are logged at start" is no longer true at SWWAF_LOG_LEVELwarn or error, which hold back the line written at start that carries them. Acceptable: the README says so, in that sentence or in the SWWAF_LOG_LEVEL entry.
Judgement call: the line with the settings held back at warn and error taken as intended, since "Configuration surface" in SPEC.md lists start-up messages among those SWWAF_LOG_LEVEL filters.
Judgement call accepted: after SWWAF_IPV6_GROUP_PREFIX changes, an IPv6 client starts afresh under its new group while old bans keep refusing their netblocks.
Judgement call accepted: debug writes what info does while no message is at debug.
Judgement call accepted: the logger at error until the settings are read, since the one message then is an invalid setting's error.
Judgement call accepted: the range 32 to 128.

The IPv6 group that is one client, the size of the table of clients and
the level of the process's own lines become settings. clientGroup reads
the group length from them, so limits, bans, history, lookups, AbuseIPDB
scores and per-client anomaly counters all follow it; ratelimit.New
takes the table size; the process logger takes the level once the
settings are read, and request lines, written apart from it, are never
held back.
Judgement call: SWWAF_IPV6_GROUP_PREFIX accepts 32 to 128, the issue's example range.

smallwebwaf now listens on port 0 in the level test, which waits for the warning written when a list cannot be fetched; freeAddress and waitUntilServing are gone, and the check that no request line is held back moved to TestLogLevelHoldsBackNoRequestLine in internal/proxy.
The opening of "Settings" in README.md now says that warn and error hold back the line with the effective settings.

Judgement call accepted: the level test waits for the warning from its own local list server no longer than the other tests in the file wait, and only checks which lines were held back once smallwebwaf has stopped.
