In `@src/ansiblelint/rules/event_query.py`:
- Around line 134-195: The query validation in the event-query rule currently
accepts top-level tokens instead of validating the actual output object's facts
members. Update the validation around the device_type and canonical_facts checks
to parse and inspect their respective output locations, require
facts.device_type, and reject null or empty canonical_facts; preserve the
existing taxonomy and identifier validation for valid objects. Add a failing
fixture covering canonical_facts: null, an empty facts object, and a top-level
device_type.
- Around line 102-107: Update the loop handling module_key in the event-query
validation flow to guard non-string YAML mapping keys before calling startswith
or _FQCN_PATTERN.match. Report such keys as invalid FQCNs through the existing
validation path instead of raising AttributeError, while preserving the current
handling for string keys and private keys.

Hi @stevefulme1 . Can you please rebase the branch and push verified commits. Once done I should be able to approve it |
Adds a new rule (event-query) that validates extensions/audit/event_query.yml files used for AAP indirect node counting. These files define jq queries that extract managed node identity from Ansible module return data across collections (VMware, Microsoft AD, cloud providers, network devices, etc.). Checks: - Module keys use valid FQCN format (namespace.collection.module) - Each entry has a required 'query' field - Query output produces required fields (name, canonical_facts, facts) - facts.device_type uses values from a normalized taxonomy - canonical_facts defines at least one non-null unique identifier Includes documentation (event_query.md) with the full normalized device_type taxonomy and problematic/correct code examples, plus 5 test fixtures. Ref: AAP-47265 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Use != instead of not == (SIM201) - Use list.extend instead of append in loop (PERF401)
- Add 'esxi' and 'moid' to cspell dictionary (VMware terms used in event_query examples) - Whitelist EventQueryRule in vulture (false positive — class is loaded dynamically by ansible-lint's rule discovery)
Guard non-string YAML mapping keys before calling string methods to prevent AttributeError on integer/float keys. Scope device_type validation to the facts output block instead of accepting top-level tokens. Detect canonical_facts: null as empty. Add test fixtures for both scenarios.
- Add validation for scalar canonical_facts values (e.g., `.id`) that previously bypassed the object check silently - Fix facts-block regex using \b anchor so `facts:` no longer matches inside `canonical_facts:` - Add failing fixture for scalar canonical_facts

Bug: Test Assertion Order (Blocker — Will Fail in CI)
event_query.py:302–311 — The null-canonical-facts parametrized case expects:
["event-query[canonical-facts-empty]", "event-query[device-type-missing]"]But the code generates errors in this order (following the logic at lines 176–224):
device-type-missing— facts block found, nodevice_typeinsidecanonical-facts-empty—canonical_facts: nullmatched
The assertion loops by index (result.tag == expected[index]), so the reversed order will cause the test to fail. This is likely why the local test run was blocked — it would have surfaced immediately.
Bug: Nested-Brace Regex Breaks on Real jq Queries (High)
event_query.py:176:
re.search(r"\bfacts\s*:\s*\{([^}]*)\}", query, re.DOTALL)[^}] cannot handle nested braces. Any jq that nests objects inside facts — e.g.:
facts: {
device_type: "vm",
metadata: { platform: "aws" }
}will produce a truncated facts_content at the first }, causing a false device-type-missing violation on valid files.
Bug: Path Check Doesn't Enforce Segment Order (High)
event_query.py:90–92:
if "extensions" not in parts or "audit" not in parts:
return []This accepts audit/extensions/event_query.yml (wrong order) and extensions/unrelated/event_query.yml (non-adjacent). The spec requires extensions/audit/ as consecutive segments. Fix:
try:
ext_idx = parts.index("extensions")
if parts[ext_idx + 1] != "audit":
return []
except (ValueError, IndexError):
return []Wrong version_changed (Medium)
event_query.py:75 — version_changed = "25.0.0" but the project is currently at 26.8.1.dev5. Should be "26.9.0" (or the next planned release).
Code: Redundant Else Branches (Low)
event_query.py:195–208 — Both branches produce the exact same error:
elif "device_type" not in query:
results.append(...) # device-type-missing
else:
results.append(...) # also device-type-missing, same messageCollapse into a single else.
Code: Silent Case-Folding is Undocumented (Medium)
event_query.py:216:
normalized = device_type.lower().replace(" ", "_")
if normalized not in VALID_DEVICE_TYPES:"Virtual Machine" silently passes as valid virtual_machine. This is surprising — either require an exact match or document this leniency in the rule description and .md file.
Minor: No Line Numbers in Match Errors (Low)
All create_matcherror calls omit linenumber, so every finding anchors to line 1. For files with multiple module entries this makes it difficult to locate which entry triggered the violation.
- Fix test assertion order to match code execution order (blocker) - Replace [^}] regex with brace-counting helper for nested jq objects - Enforce consecutive extensions/audit/ path segments - Update version_changed to 26.9.0 - Remove silent case-folding for device_type (require exact match) - Collapse redundant else branches - Add nested-braces passing fixture - Document exact-match requirement in event_query.md
