Signals

Ordered by severity, then signals introduced in this release. Hidden characters are shown as ⟨U+…⟩.

info ~~warn~~ → info by review dynamic-execution ci_tools/retry.sh:6:5

command name is a variable (`$@`) not set in this file — the caller or environment decides what runs (ast pass, confidence 0.70)
```
for i in `seq 1 $n_retries`; do
    "$@" && exit 0
    sleep $sleep_time
done
```
likely benign LLM, confidence 0.90 A bash CI helper that retries a caller-provided command a set number of times with a sleep between attempts.
Reasoning
This is a standard retry wrapper: it loops a fixed number of times, runs the passed-in command with "$@", exits on success and sleeps between attempts. Running an argument-supplied command is the entire purpose of such a helper, and nothing in the snippet is encoded, hidden, or fetched from elsewhere. The dynamic-execution flag only reflects that the command is caller-supplied, which is expected for a CI retry script.
info dynamic-execution ci_tools/run_tz_master_env.sh:88:1

command name is a variable (`$CITOOLS_DIR`) that this file sets only to plain text (ast pass, confidence 0.40)
```
ZONEFILE_METADATA_NAME=zonefile_metadata_master.json
${CITOOLS_DIR}/make_zonefile_metadata.py \
    $TARBALL_NAME \
    $VERSION \
```
