Don't spend a repair attempt on a fully self-fixed JSONB path check - #485
JsonbPathCheckAgent.execute incremented jsonb_path_repair_attempts unconditionally, including on the branch where try_self_apply_fixes resolved every mismatch and the function returns valid_sql with no reconstruction needed. Its own docstring says it "mirrors join_path_check.py's bounded counter," but join_path_check.py's equivalent early return (if not mismatches and not case_dirty:) happens beforejoin_path_repair_attempts is incremented, with an explicit comment: "Not counted against join_path_repair_attempts below: a fully self-applied fix isn't a reconstruction round spent." The jsonb sibling never carried that guard over.
Per this file's own comment, ~93% of historical firings are the fully self-fixable flattened-dotted-key shape — the common case silently burns down the attempt budget for free. Once jsonb_path_repair_attempts reaches _MAX_REPAIR_ATTEMPTS, the top-of-function guard (attempts >= _MAX_REPAIR_ATTEMPTS) skips the check entirely and returns valid_sql without ever probing — so a request that happens to hit two fully-self-fixed passes first can then let a real, unprobed JSONB key-path mismatch through as "valid" on a later pass, defeating the check's stated purpose (catching NULL-producing wrong-key JSONB access before execution).
Fix
Move the jsonb_path_repair_attempts increment to after the if not mismatches: return valid_sql early return, matching join_path_check.py's pattern exactly.
Verification
Reproduced the consequence with a standalone simulation of both the old and new guard/counter logic across 3 calls (two fully self-fixed, one with a real remaining mismatch): old logic exhausts the 2-attempt budget on the two free passes and then skips probing the real mismatch entirely; new logic reserves the budget, so the real mismatch still reaches the reconstruction path.
Summary by CodeRabbit
Bug Fixes
Successful JSONB path corrections now return valid SQL without increasing the repair-attempt count.
When a mismatch remains after correction, the repair attempt is counted and the issue continues through the repair process. This keeps the count focused on unresolved mismatches and ensures the reported SQL status reflects whether the correction resolved the issue.
JsonbPathCheckAgent.execute incremented jsonb_path_repair_attempts
unconditionally, including on the branch where try_self_apply_fixes
resolved every mismatch and the function returns valid_sql with no
reconstruction needed. Its own docstring says it "mirrors
join_path_check.py's bounded counter," but join_path_check.py's
equivalent early return (not mismatches and not case_dirty) happens
BEFORE join_path_repair_attempts is incremented, with an explicit
comment: "Not counted against join_path_repair_attempts below: a fully
self-applied fix isn't a reconstruction round spent." The jsonb sibling
never carried that guard over.
Per this file's own comment, ~93% of historical firings are the fully

reaches _MAX_REPAIR_ATTEMPTS, the top-of-function guard
(attempts >= _MAX_REPAIR_ATTEMPTS) skips the check entirely and returns
valid_sql without ever probing -- so a request that happens to hit two
fully-self-fixed passes first can then let a real, unprobed JSONB
key-path mismatch through as "valid" on a later pass, defeating the
check's stated purpose (catching NULL-producing wrong-key JSONB access
before execution).
Verified the consequence with a standalone simulation of both the old

entirely (SKIPPED_NO_PROBE); new logic reserves the budget, so the real
mismatch still reaches the reconstruction path.
Fix: move the jsonb_path_repair_attempts increment to after the
"if not mismatches: return valid_sql" early return, matching
join_path_check.py's pattern exactly.

Walkthrough
The JSONB path check agent now returns valid SQL without counting a repair attempt when self-applied fixes resolve all mismatches. If mismatches remain, it increments the counter before continuing repair. Tests cover both outcomes.

Summary
Check mismatches before counting repair attempts auto_ontology/retrieval/text_to_sql/agents/jsonb_path_check.py, auto_ontology/tests/test_jsonb_path_check_counter.py
The agent returns valid_sql when no mismatches remain after self-applied fixes. Otherwise, it increments jsonb_path_repair_attempts before proceeding. Tests verify both outcomes.

- Line 122: Add an agent-level regression test for the JSONB path repair counter
behavior: exercise two fully self-applied fixes followed by a remaining
mismatch, and assert the counter is preserved for the first two calls while the
third increments it and returns invalid_sql. Place the test under the
established test area and use the existing agent setup and repair interfaces.

Covers the behavior from d97ffc3: two calls where every mismatch is
fully self-applied leave jsonb_path_repair_attempts untouched, and a
call with a mismatch surviving the self-apply pass spends an attempt
and routes to reconstruction.
Mocks ProbeExecutor, resolve_connector_from_tables, and the two
db_probe.jsonb_path_check functions so the test exercises
JsonbPathCheckAgent.execute directly without a live database.

Per CodeRabbit review on PR NVIDIA#485: the previous two tests each started
from a fresh state instead of chaining a single three-call sequence,
so they didn't actually prove the counter survives across calls.
Replaced with one test that threads the returned path_state through
three agent.execute() calls: the first two self-apply fully (counter
untouched, valid_sql), the third leaves a mismatch after the self-apply
pass (counter spent, invalid_sql).
Also added type hints to the new helpers and test functions per the
repo's coding guideline requiring them on all signatures.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Replace the call_index coupling in fake_self_apply with an explicit sequence.
fake_self_apply infers the call number from find_mismatches.call_count. This ties the test to the call order of two mocks in the agent. If the agent calls find_jsonb_path_mismatches more than once per execute(), the first two calls can return the unfixed branch. The assertions then fail for a reason that does not relate to the counter. A side_effect list on a MagicMock for try_self_apply_fixes states the intent directly.

Per CodeRabbit review on PR NVIDIA#485: fake_self_apply inferred which
response to return from find_mismatches.call_count, coupling it to
find_jsonb_path_mismatches's own call count. A MagicMock with an
explicit side_effect list states the intended per-call sequence
directly and doesn't break if the agent's internal call order shifts.
Also dropped the now-unused List/Tuple imports.

find_mismatches and fake_self_apply use argument-insensitive side_effect lists. The test only asserts outcomes (decision and the counter). The test would still pass if JsonbPathCheckAgent.execute passed the wrong sql_code, dialect, or mismatches to these functions.
The risk is real here. After a self-applied fix, execute updates sql_code in path_state. The second and third calls should then receive different SQL than the first. The test does not check this.
Add call_args_list checks, or use assert_has_calls. For example, check that try_self_apply_fixes receives [mismatch] and the sql_code stored in path_state on each call.
Place these lines after the third execute call. Align the expected SQL values with the actual _get_sql_code behavior.
