that completed items remain as history.
- Line 119: Rename or merge the duplicate “P1 — Pre-v1.0 or Shortly After”
heading so the document contains only one unique P1 heading and avoids duplicate
Markdown anchors.
In `@docs/telemetry.md`:
- Line 29: Update the fenced code blocks for the metric example and span example
in the telemetry documentation to include language identifiers, using text for
metric output and csharp or text for the span example, so both fences satisfy
markdownlint MD040.
- Line 26: Make the telemetry counter tag contract consistent by either adding
strategy="retry" to the example metric and ensuring every counter includes the
strategy tag, or removing strategy from the counter-tag table if counters do not
emit it; keep the documented tags aligned with the actual counter emission.
- Line 37: Update the telemetry documentation describing strategy execution
spans to reflect the implementation: state that StartActivity is conditional,
exclude the synchronous HedgingStrategy.Execute path, name spans using
strategy.name, and document only tags actually emitted, removing claims about
attempt and duration_ms.
In `@README.md`:
- Line 409: Update the performance conclusion in the README to qualify
Resilion’s speed advantage as applying to the listed multi-strategy scenarios,
rather than claiming it is consistently faster overall. Ensure the statement
remains consistent with the empty-pipeline result showing Resilion slower than
Polly.Core.
In `@samples/Resilion.Samples/Samples/TypedRetrySample.cs`:
- Line 33: Update the retry handling around the typed retry delegate and retry
callback so every discarded HttpResponseMessage, including the 503 responses
from attempts 1 and 2, is disposed before the next retry; retain disposal of the
final result and avoid disposing a response that will be returned.
In `@src/Resilion/CircuitBreaker/CircuitBreakerStateMachine.cs`:
- Around line 281-289: Update GetEffectiveBreakDuration to validate the value
returned by _breakDurationGenerator and clamp zero or negative durations to a
positive duration before returning it; preserve the existing _breakDuration
fallback when no generator is configured.
- Around line 315-332: Update Isolate and Reset to create the appropriate
CircuitStateChangedEvent using a ResilienceContext while holding _lock, then
dispatch it outside the lock so manual transitions trigger the existing
OnOpened/OnClosed callbacks and CircuitBreakerStateChanges counter consistently
with TryReject and RecordOutcome.
In `@src/Resilion/Hedging/HedgingStrategy.cs`:
- Line 166: Update the validation in Execute around HedgingDelay to reject
non-sequential modes only when MaxHedgedAttempts is greater than 1, allowing
synchronous execution with the default delay when only the primary attempt can
run.
In `@src/Resilion/Internal/PipelineComponent.cs`:
- Around line 90-94: Update DisposeAsync at
src/Resilion/Internal/PipelineComponent.cs lines 90-94 and 195-199 so
_next.DisposeAsync() executes from a finally path even when
_strategy.DisposeAsync() throws; preserve exception propagation while ensuring
both pipeline components are disposed.
In `@src/Resilion/PipelineBuilder.cs`:
- Line 170: Update the empty-pipeline branches in PipelineBuilder.Build methods
at src/Resilion/PipelineBuilder.cs lines 170-170 and 293-293 to preserve Name:
construct named Pipeline and Pipeline<TResult> instances when Name is set, while
retaining the existing unnamed Empty instances when it is not.
In `@src/Resilion/PipelineOfT.cs`:
- Around line 63-65: Update ExecuteOutcomeAsync to assign context.PipelineName =
_name after its null checks and before calling _component.ExecuteAsync, matching
the context initialization used by the other pipeline execution path.
In `@tests/Resilion.Tests/Hedging/HedgingStrategyTests.cs`:
- Line 521: Update the primary attempt in the hedging test around the callback
returning “winner” so it waits for a signal from the losing callback before
completing, ensuring the losing attempt has started first. Use a bounded wait
for the signal to avoid hanging the test, while preserving the existing
elapsed-time and cleanup assertions.
In `@tests/Resilion.Tests/Retry/RetryStrategyTests.cs`:
- Around line 448-449: Update the retry test around the fakeTime.Advance call to
remove the fixed real-time delay and advance the fake clock in a bounded loop
until executeTask completes, preserving a timeout or assertion if completion
does not occur within the bound.

Nitpick comments:
In `@src/Resilion/CircuitBreaker/CircuitBreakerStateMachine.cs`:
- Line 107: Add an asynchronous rejection path alongside TryReject that exposes
the pending event, then update CircuitBreakerStrategy.ExecuteAsync and
CircuitBreakerTypedStrategy.ExecuteAsync to await FireEventAsync for that event
instead of invoking synchronous FireEvent. Preserve the existing synchronous
TryReject and FireEvent behavior for non-async callers.
In `@src/Resilion/CircuitBreaker/CircuitBreakerStrategyOptions.cs`:
- Around line 199-202: Rename the public BreakDurationGeneratorArgs.FailureCount
member to TripCount to reflect that it contains the circuit trip count, then
update CircuitBreakerStateMachine.GetEffectiveBreakDuration and all samples and
documentation that construct or access this argument to use the new name
consistently.
In `@src/Resilion/CircuitBreaker/CircuitBreakerTypedStrategy.cs`:
- Line 33: Add the same CircuitBreaker tracing activity used by
CircuitBreakerStrategy to the typed strategy around TryReject, tagging
strategy.name, pipeline.name, operation.key, and outcome on both execution paths
so typed pipelines emit equivalent breaker spans.

Inline comments:
In `@src/Resilion.Extensions/PublicAPI.Unshipped.txt`:
- Around line 6-11: Regenerate the public API baseline for
IPipelineProvider<TKey> using analyzer version 3.3.4. Remove the namespace
declaration, emit fully qualified API signatures with parameter names such as
key, configure, and pipeline, and preserve `#nullable` enable while retaining
other # lines as comments.
In `@src/Resilion/PublicAPI.Unshipped.txt`:
- Around line 88-89: Remove the Pipeline.Component.get and Pipeline.Name.get
entries from PublicAPI.Unshipped.txt to match their internal accessibility in
Pipeline and PipelineComponent; do not change visibility unless public exposure
is explicitly intended.
- Around line 82-84: Remove the invalid checked markers from the
Outcome<TResult> API baseline entries for equality and implicit conversion, and
from the ResiliencePropertyKey<TValue> equality entries. Regenerate the affected
declarations so they use the ordinary ==, !=, and implicit signatures without
checked.
- Around line 6-11: Regenerate the public API baselines from the compiled API so
extension method entries use fully qualified symbol names and include static,
this, and parameter names. Update both src/Resilion/PublicAPI.Unshipped.txt
(lines 6-11) and src/Resilion.RateLimiting/PublicAPI.Unshipped.txt (lines 6-17);
apply the generated analyzer format to every affected entry.
