In `@airbyte_cdk/sources/declarative/models/declarative_component_schema.py`:
- Around line 101-106: Add a non-negative constraint to the
jitter_range_in_seconds model by updating its Field to include a minimum (e.g.,
ge=0) and add a Pydantic field validator named like
validate_jitter_range_in_seconds that accepts templated strings but rejects
numeric values < 0; this will ensure literal negative numbers
(jitter_range_in_seconds) fail model validation early while still allowing
template strings. Also apply the same change to the other occurrence mentioned
(the similar jitter_range_in_seconds field at the later block).
In `@unit_tests/sources/declarative/parsers/test_model_to_component_factory.py`:
- Around line 1757-1812: The test test_create_requester_with_backoff_jitter
currently asserts jitter_range_in_seconds.eval(...) == 15 for both literal and
interpolated cases which masks wiring bugs; change the YAML literal case to use
a distinct literal value (e.g. backoff_time_in_seconds: 60 and
jitter_range_in_seconds: 7) and keep the interpolated case using "{{
config['backoff_jitter'] }}" then when calling factory.create_component pass
config={"backoff_jitter": 15} and assert the literal case yields 7 while the
interpolated case yields 15 by checking
backoff_strategy.jitter_range_in_seconds.eval(...) accordingly; reference the
test name (test_create_requester_with_backoff_jitter), the backoff_strategy_yaml
parameter, factory.create_component, and jitter_range_in_seconds to locate where
to change the values and assertions.
In
`@unit_tests/sources/declarative/requesters/error_handlers/backoff_strategies/test_constant_backoff.py`:
- Around line 65-88: In test_constant_backoff_with_jitter_bounds, after
collecting backoff_times from ConstantBackoffStrategy.backoff_time, add an
assertion that when jitter_range_in_seconds (jitter_range) is non-zero the
results vary (e.g., assert len(set(backoff_times)) > 1) to ensure jitter is
applied, and conversely when jitter_range is zero assert len(set(backoff_times))
== 1 to ensure deterministic output; reference the test function name, the
backoff_times list and ConstantBackoffStrategy.backoff_time to locate where to
insert the checks.
In
`@unit_tests/sources/declarative/requesters/error_handlers/backoff_strategies/test_exponential_backoff.py`:
- Around line 47-70: The test currently only checks bounds but not that jitter
actually varies; update test_exponential_backoff_with_jitter_bounds to verify
variability by either (A) asserting that the 2000 sampled backoff_times are not
all identical (e.g., assert len(set(backoff_times)) > 1) so jitter changes
values, or (B) monkeypatch/patch random.uniform used by
ExponentialBackoffStrategy.backoff_time and assert it was called (or return
different values) to exercise jitter; reference
ExponentialBackoffStrategy.backoff_time and random.uniform when adding the
variation check or monkeypatch.

107-112:⚠️ Potential issue | 🟡 Minor | ⚡ Quick winPast review concern about non-negative constraint still applies, wdyt?
The earlier review correctly noted that
jitter_range_in_secondslacks a non-negative constraint. Addingge=0to both fields (here and in the source YAML) would catch literal negative values at schema validation time—before they reach the runtimeValueErrorcheck. Template strings like"{{ config['jitter'] }}"would still pass through, which is the intended behavior.For consistency,
AsyncRetriever.failed_retry_wait_time_in_seconds(line 3092) already usesge=1.📋 Suggested fix
In the source YAML (airbyte_cdk/sources/declarative/declarative_component_schema.yaml), add a minimum constraint to the
jitter_range_in_secondsproperty definitions for bothConstantBackoffStrategyandExponentialBackoffStrategy, then regenerate this model file. For example:jitter_range_in_seconds: type: - number - string minimum: 0 # ... rest of definitionAfter regeneration, the Pydantic Field should include
ge=0.Also applies to: 521-526

Apologies for the comment noise. I will stop posting PR status updates unless there is a concrete CI failure analysis/fix that reviewers need. |

I’m moving CI investigation updates back to the Devin session to avoid further PR noise. I’ll only comment here again if there is a concrete failure analysis or fix reviewers need. |

3 primary comments:
- remove string interpolation. should just be defined by connector dev w/ value in the manifest, unless there is an argument for interpolated values that I'm unaware of
- move the jitter value validation eval to the model to component factory
- and I'm concerned about cases where configured jitter could result in backoff times of 0, which defeats the purpose of having a backoff time. See my recommendation in the constant back off strategy file, but look up what would be considered best practice

494-500: ⚡ Quick winConsider clarifying the jitter behavior or adjusting the naming.
The current implementation applies asymmetric jitter that only increases the backoff time by
[0, jitter_range_in_seconds * 2]. Traditional jitter implementations are typically symmetric (e.g.,backoff ± jitter), which helps prevent thundering herd while keeping the average backoff time close to the configured value.The name "jitter_range_in_seconds" might lead users to expect that the total variation range is
jitter_range_in_seconds, but it's actuallyjitter_range_in_seconds * 2(only in the positive direction).A few options to consider:
- Rename to something like
max_jitter_in_secondsto clarify it's the maximum addition- Update the description to emphasize this is asymmetric jitter that only increases backoff
- Consider changing to symmetric jitter:
random.uniform(max(0, backoff_time - jitter_range), backoff_time + jitter_range)The same applies to ExponentialBackoffStrategy (lines 2044-2050).

- Line 2069: The test
test_given_unmigrated_config_when_migrating_then_config_is_migrated currently
uses migration_mocks["open"].assert_any_call("/fake/config/path", "w"); tighten
this to migration_mocks["open"].assert_called_once_with("/fake/config/path",
"w") because ManifestDeclarativeSource writes config_path only once in
_migrate_and_transform_config (invoked during __init__) and other related mocks
(emit_message, json_dump) are already asserted to be called once; if your
changes actually cause multiple opens, replace assert_any_call with
assert_called_once_with and if keeping assert_any_call is required add a short
inline comment explaining why multiple open() calls are expected (e.g.,
additional reads/writes from new logic) and reference ManifestDeclarativeSource
and _migrate_and_transform_config in the comment.

a range but is used asymmetrically (only adds up to jitter_range_in_seconds * 2

behavior and the actual applied range (i.e., backoff_time_in_seconds ..
backoff_time_in_seconds + jitter_range_in_seconds * 2), and apply the same
clarification to the ExponentialBackoffStrategy entry; alternatively, if you
prefer symmetric jitter, rename the field to max_jitter_in_seconds (or
min_max_jitter) and update both the schema descriptions and any corresponding
implementation that uses jitter_range_in_seconds so the behavior and name match
(either implement symmetric sampling backoff ± jitter_range or change docs/name
