Understand the root cause of the following 27 issues and fix them.


<file name="src/collectors/log2journal/tests.d/logic-key-validation.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/logic-key-validation.yaml:2">
`invalid_key` is limited to `\w+`, so keys containing dashes, dots, or other special characters will not be captured and the test never exercises those cases. Use a non-whitespace class instead so the invalid characters remain part of the match.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/boundary-single-item-arrays.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/boundary-single-item-arrays.yaml:8">
`inject` is meant to be a single-item array in this boundary test, but a second element (`INLINE_SINGLE`) is still present, so the scenario isn’t actually covered and regressions on single-element `inject` arrays will slip through.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/real-world-apache-logs.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/real-world-apache-logs.yaml:7">
The pattern for APACHE_BODY_BYTES_SENT only accepts digits, but Apache emits `-` when the body size is zero, so those log lines will fail to match. Please allow `-` as well so all combined-log entries are parsed.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/real-world-multiline-stack.input">

<violation number="1" location="src/collectors/log2journal/tests.d/real-world-multiline-stack.input:1">
The multiline stack trace fixture is now a single line with literal \n escapes, so the test no longer exercises multi-line parsing. Replace the escapes with real newline-separated lines.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/advanced-pcre2-complex.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/advanced-pcre2-complex.yaml:8">
Escape the dot in the timestamp pattern so only literal `.` characters are accepted.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/logic-rename-chains.output">

<violation number="1" location="src/collectors/log2journal/tests.d/logic-rename-chains.output:2">
The rename chain output should expose the final key; this line still shows the intermediate name and the chained reference entry is missing. Please update the expectation to use FINAL_NAME and include the chained reference result.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/README.md">

<violation number="1" location="src/collectors/log2journal/tests.d/README.md:73">
The count of YAML parsing tests is outdated. There are 6 `risk-*.yaml` files and 4 `yaml-*.yaml` files in tests.d today, so this section should state 10 tests, not 13.</violation>

<violation number="2" location="src/collectors/log2journal/tests.d/README.md:83">
The Unicode/encoding test count is overstated. The directory currently has four `unicode-*.yaml`, one `encoding-*.yaml`, and one `variable-substitution-unicode.yaml`, so this should say 6 tests instead of 8.</violation>

<violation number="3" location="src/collectors/log2journal/tests.d/README.md:121">
The boundary test count is inaccurate. There are five `boundary-*.yaml` and five `edge-*.yaml` files in tests.d, so this section should reference 10 tests instead of 12.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/nginx-json.input">

<violation number="1" location="src/collectors/log2journal/tests.d/nginx-json.input:7">
`time_local` cannot contain a seconds value of 60; please adjust this entry to a valid timestamp.</violation>

<violation number="2" location="src/collectors/log2journal/tests.d/nginx-json.input:9">
`time_local` includes an 80-second value, which is outside the allowed range; please correct the timestamp.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/logic-filter-behavior.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/logic-filter-behavior.yaml:18">
The include regex uses uppercase LEVEL/MODULE/MESSAGE even though the pattern emits lowercase keys level/module/message, so those fields would be filtered out instead of kept.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/pcre2-advanced-patterns.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/pcre2-advanced-patterns.yaml:28">
The STATUS_FAMILY rewrite never fires because the key is never populated before matching, so the derived family field is missing from the output.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/full.output">

<violation number="1" location="src/collectors/log2journal/tests.d/full.output:2">
The expected key names now include a duplicated prefix (for example `NGINX_NGINX_BODY_BYTES_SENT`) even though the config already prefixes the capture groups. This breaks downstream injections/rewrite logic that still references keys like `${NGINX_STATUS}`, so fields such as PRIORITY disappear.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/boundary-key-length.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/boundary-key-length.yaml:4">
The supposed 64-character journal field key is only 63 characters long, so this test no longer exercises the true boundary condition. Please add one more character so the key reaches 64 characters.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/boundary-max-items.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/boundary-max-items.yaml:19">
This boundary test never reaches the documented 512-entry limits: only 11 inject items and 3 rewrite/rename items are defined, so the parser’s maximum handling is untested. Please materialize all 512 entries (or generate them programmatically) so the limit is actually exercised.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/logic-variable-substitution.output">

<violation number="1" location="src/collectors/log2journal/tests.d/logic-variable-substitution.output:2">
This expected output now leaves BASE_MSG with empty user/action fields, so the test would pass even if variable substitution fails. Please restore the expected filled-in values instead of the blank ones.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/precedence-test-config.input">

<violation number="1" location="src/collectors/log2journal/tests.d/precedence-test-config.input:1">
The precedence test input should include level, user, and action tokens so it matches the regex defined in the YAML; otherwise the case never exercises the config precedence logic.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/pcre2-named-groups.input">

<violation number="1" location="src/collectors/log2journal/tests.d/pcre2-named-groups.input:1">
The sample log entry no longer matches the configured PCRE2 pattern (missing `[thread]` and `class - message`), so the test cannot capture the named groups and the downstream rewrites fail.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/encoding-special-chars.output">

<violation number="1" location="src/collectors/log2journal/tests.d/encoding-special-chars.output:6">
The MESSAGE expectation drops both ${prefix} and ${content} even though the rewrite template is `Encoded[${prefix}] = ${content}`, so the test would miss regressions where template substitution breaks.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/edge-special-chars.output">

<violation number="1" location="src/collectors/log2journal/tests.d/edge-special-chars.output:2">
The expected value for DOLLAR_BRACES should still include the ${message} replacement; otherwise this test no longer catches broken variable expansion.</violation>

<violation number="2" location="src/collectors/log2journal/tests.d/edge-special-chars.output:6">
TEST_REWRITE should still include the captured ${message}; updating the expected output to omit it means the test no longer verifies the substitution works.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/advanced-filter.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/advanced-filter.yaml:22">
The include regex omits the ALSO_KEEP key, so the test will drop that injected value even though this scenario is meant to keep it. Update the include pattern to cover ALSO_KEEP.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/logic-key-validation.output">

<violation number="1" location="src/collectors/log2journal/tests.d/logic-key-validation.output:8">
The expected output still contains the raw `key-with-dashes` field, but journald key names must be normalized (uppercase with underscores). This contradicts the test&#39;s own docstring and will produce journal entries that systemd rejects.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/error-messages-validation.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/error-messages-validation.yaml:8">
`inject` must be an array of objects (`- key`, `value`). Defining it as a plain mapping makes the parser fail on `.inject` itself, so this test never exercises the rewrite error cases it describes.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/edge-long-strings.input">

<violation number="1" location="src/collectors/log2journal/tests.d/edge-long-strings.input:1">
The edge-long-strings test is supposed to validate handling of very long log lines, but this change reduces it to a short message, so the edge case is no longer exercised. Please restore a genuinely long input line here to keep the test meaningful.</violation>
</file>

<file name="src/collectors/log2journal/tests.d/complex-rewrite-pipeline.yaml">

<violation number="1" location="src/collectors/log2journal/tests.d/complex-rewrite-pipeline.yaml:61">
The SEVERITY rewrite never matches because it compares the key’s current value &quot;0&quot; against the LOG_LEVEL text, so severity stays at 0 instead of reflecting INFO/WARNING/ERROR.</violation>
</file>
