SQL currently evaluates resource/scope transport markers as log rows. A WHERE clause can delete those markers and strip metadata from surviving OTLP logs; projection can also alter the envelopes. This remains reproducible after the FTS merge.

Skip non-normal log events before applying SQL row processing. Existing group normalization removes envelopes whose logs were all dropped.

For two resource groups containing IDs 1–4, SELECT * FROM STREAM WHERE id = 1; retains ID 1 with its original resource/scope metadata, removes the now-empty second group, and reports one logical output record. The fix is independent of processor fusion in #12505.

Rebased onto master 05048e35d. Validation:

• Unmodified post-FTS master fails four metadata-preservation cases; its two empty-batch cases pass.
• This branch's six integration cases pass normally and under strict Valgrind: keep all groups, partial/whole-group drops, and empty batch, in input/output contexts with filesystem storage and two-route fan-out.
• Tests compare resources/scopes, schema URLs, body, timestamps, severity, trace/span IDs, flags, attributes and logical counters.
• All six Memcheck processes report zero errors and zero definite/indirect/possible leaked bytes.
• flb-it-processor_sql passes; full rebased PR range passes prefix lint.

From the repository root, with FLUENT_BIT_BINARY pointing at this branch's build:

python -m pytest tests/integration/scenarios/processor_sql -q
VALGRIND=1 VALGRIND_STRICT=1 python -m pytest tests/integration/scenarios/processor_sql -q
ctest --test-dir build -R '^flb-it-processor_sql$' --output-on-failure

No public configuration, packaging or bundled-library changes. Target: master.
