Request log lines gain the fields "Request log" in SPEC.md lists whose features are built, described in README.md, for #79.
New settings SWWAF_INSTANCE_NAME (default: the host's name) and SWWAF_LOG_REQUEST_HEADERS. An entry of the latter that is not a header name, or is Host or Transfer-Encoding (Go's server takes both out of the request), stops the start.
request_id is a trusted proxy's X-Request-ID or a new random one, sent on to the app; an untrusted peer's is replaced. scheme believes X-Forwarded-Proto only from a trusted proxy.
Authorization, Cookie and Set-Cookie values are never logged; has_authorization and has_cookie say whether the first two were sent.
The health answer sets its own Content-Type, which Go's server would add after the log line.
Optional timings are pointers in requestlog.Line, so one under a microsecond is logged as zero.
ratelimit.Limiter.Count also returns the client's counts in each window.
requestlog.Line's fields follow SPEC.md's order.
Left for their features: asn, as_name, limit_percent, rule_ids, waf_rule_ids, waf_score, reputation, duration_waf.
Deviation: counts has request totals only; byte totals come with the byte limits.
Deviation: SWWAF_INSTANCE_NAME is on request lines only, not process lines or metrics.
Judgement call: the headers go under request_headers, a name SPEC.md does not give.
Judgement call: the issue's SWWAF_INSTANCE takes SPEC.md's name, SWWAF_INSTANCE_NAME.
Judgement call: request ids are 26 base32 characters from crypto/rand.Text; the standard library's uuid needs go 1.27.
Judgement call: header names are checked against RFC 9110's characters in a few lines, not with golang.org/x/net, which SPEC.md does not list.

Request log lines gain the fields "Request log" in `SPEC.md` lists whose features are built, described in `README.md`, for https://git.eeqj.de/sneak/smallwebwaf/issues/79.
- New settings `SWWAF_INSTANCE_NAME` (default: the host's name) and `SWWAF_LOG_REQUEST_HEADERS`. An entry of the latter that is not a header name, or is `Host` or `Transfer-Encoding` (Go's server takes both out of the request), stops the start.
- `request_id` is a trusted proxy's `X-Request-ID` or a new random one, sent on to the app; an untrusted peer's is replaced. `scheme` believes `X-Forwarded-Proto` only from a trusted proxy.
- `Authorization`, `Cookie` and `Set-Cookie` values are never logged; `has_authorization` and `has_cookie` say whether the first two were sent.
- The health answer sets its own `Content-Type`, which Go's server would add after the log line.
- Optional timings are pointers in `requestlog.Line`, so one under a microsecond is logged as zero.
- `ratelimit.Limiter.Count` also returns the client's counts in each window.
- `requestlog.Line`'s fields follow `SPEC.md`'s order.

Deviation: `SWWAF_INSTANCE_NAME` is on request lines only, not process lines or metrics.

README.md conflicts with current next: the status paragraph and the TODO list were both changed by the commit for #68. Acceptable: rebased onto next with both changes kept, and the TODO no longer naming the rest of the request log's fields.
internal/config/config.go, headerNames: SWWAF_LOG_REQUEST_HEADERS takes entries that are not header names, such as accept;origin, accept language or x-foo:. They can never match a request header, so the setting quietly logs nothing for them, where SPEC.md has invalid configuration stop the start. Acceptable: an entry that is not a valid header name stops the start with a message naming SWWAF_LOG_REQUEST_HEADERS, with such cases in TestInvalidValueStopsTheStart.
internal/proxy/proxy.go, the health answer: its log line has no response_content_type, although the client receives Content-Type: text/plain; charset=utf-8, which Go's server adds after the handler has run. README.md says the field gives the Content-Type of smallwebwaf's own answers. Acceptable: the health answer sets its Content-Type itself, and a test checks the health line's response_content_type.

internal/proxy/request.go, requestHeaders, and README.md, "Request log": host or transfer-encoding in SWWAF_LOG_REQUEST_HEADERS is never logged, because Go's server takes those two headers out of the request before smallwebwaf sees it. The setting quietly logs nothing for them, while the README says request_headers holds the request's headers that the setting names.

Each request log line now has the fields "Request log" in SPEC.md lists
whose features are built: instance (SWWAF_INSTANCE_NAME), scheme,
request_id (a trusted proxy's X-Request-ID or a new one, sent on to the
app), forwarded_for, client_group, content_type, content_length, the
headers SWWAF_LOG_REQUEST_HEADERS names, has_authorization, has_cookie,
websocket, response_content_type, cache_control, location, counts and
the timings. Authorization, Cookie and Set-Cookie values are never
logged. An entry of SWWAF_LOG_REQUEST_HEADERS that is not a header name,
or is Host or Transfer-Encoding, stops the start.
Deviation: counts has request totals only.
Deviation: SWWAF_INSTANCE_NAME is on request lines only.
Model: opus-5-5
Fixed: a request carrying only Authorization and one carrying only Cookie are now tested, and the test fails with the two fields swapped.
Fixed: only Host gets the hint about the field host, and both messages are tested.
Same kind, also fixed: the log line test now sends a body without Content-Length, so content_length and request_bytes no longer always match; the counts test now has different minute, hour and day values; and one failure message printed a timing's memory address instead of its value.
