Graceful shutdown for the workflow runtime (drain, pause, recover) (#7424)
* feat(workflows-runtime): add quiescence machinery foundation for graceful shutdown

Introduces the container-scoped quiescence signal, ingress-source contract,
burst registry, and the Interrupted workflow sub-status — the foundational
primitives the drain orchestrator and admin endpoints will build on. No
behaviour change yet: workflows continue to run and shut down exactly as
before. The new types are registered but no host-stop or pause path drives
them.

Highlights:
* IQuiescenceSignal — composable Drain + AdministrativePause flags;
  forward-only drain, reversible pause, idempotent transitions, optional
  persistence via IKeyValueStore.
* IIngressSource + IForceStoppable — uniform contract for components that
  inject external events (HTTP, schedulers, message consumers, internal
  workers, third-party modules); IIngressSourceRegistry collects and
  surfaces their states.
* IBurstRegistry — atomic counter for in-flight workflow execution
  bursts, with per-burst ingress attribution and FR-018 inconsistency
  detection (a source claiming Paused but starting bursts is flipped to
  PauseFailed).
* WorkflowSubStatus.Interrupted — new value distinct from Suspended,
  Cancelled, Faulted; semantics: "last burst force-cancelled by graceful
  drain; resumable on next runtime generation". Mirrored on the API client
  enum.
* GracefulShutdownOptions — drain deadline, per-source pause timeout,
  stimulus-queue back-pressure policy, pause-persistence policy.
  Configurable via UseWorkflowRuntime(...).ConfigureGracefulShutdown(...).
* PermissionNames.ManageWorkflowRuntime — single permission for the
  forthcoming admin pause/resume/status/force endpoints.

Implements 31 of 77 tasks for the graceful-shutdown feature
(specs/002-graceful-shutdown). Subsequent commits add the drain
orchestrator (US1 / MVP), Interrupted recovery scan (US3), admin
endpoints (US2), and first-party ingress adapters.

Tests: 25 new xUnit unit tests; 100/100 runtime unit tests pass; all
existing tests continue to pass on net8.0/net9.0/net10.0.

* feat(workflows-runtime): add drain orchestrator + host-stop integration (US1, MVP)

When the host receives a stop signal (SIGTERM, Ctrl+C, orchestrator
rollout), the runtime now drains gracefully: ingress sources are paused
in parallel, in-flight workflow bursts run to their next natural
persistence boundary within a configurable deadline, and any burst that
breaches the deadline is force-cancelled and persisted with the
Interrupted sub-status plus a forensic WorkflowInterrupted log entry.

This is the MVP — without the activation-time recovery scan (PR 3) the
existing timeout-based RestartInterruptedWorkflowsTask still picks up
Interrupted instances, just on its periodic cadence. No regression in
that recovery path (SC-008).

Highlights:
* IDrainOrchestrator + DrainOrchestrator — protocol per the contract:
  BeginDrainAsync → parallel ingress pause with per-source timeouts +
  IForceStoppable escalation → poll BurstRegistry.ActiveCount until zero
  or deadline → on breach iterate live handles, cancel, persist
  Interrupted, write log entry. All exceptions are captured into the
  returned DrainOutcome; only second-invocation throws.
* Deadline clamping: effective deadline is min(GracefulShutdownOptions.
  DrainDeadline, HostOptions.ShutdownTimeout - 500ms safety epsilon),
  so the runtime never outlives its host process.
* DrainOrchestratorHostedService — IHostedService.StopAsync wakes the
  orchestrator on host stop. Registered AFTER the heartbeat
  (Elsa.Hosting.Management) so reverse-order shutdown keeps the
  heartbeat alive throughout drain. Prevents sibling-node crash recovery
  from false-positive-recovering instances we are gracefully handling
  here (FR-029).
* BurstTrackingMiddleware — workflow-execution-pipeline middleware that
  registers a BurstHandle for the lifetime of every burst. All nine
  IWorkflowRunner.RunAsync overloads ultimately funnel into
  pipeline.ExecuteAsync(context), so this single middleware covers the
  three "burst choke points" the spec references without nine separate
  decorators. Added to UseDefaultPipeline().
* Ingress attribution: optional IngressSourceName property on
  DispatchStimulusRequest, DispatchWorkflowDefinitionRequest, and
  DispatchWorkflowInstanceRequest. Adapters set it; the middleware reads
  it via WorkflowExecutionContext.TransientProperties (helpers in
  IngressAttributionExtensions). The BurstRegistry uses the name to
  detect the FR-018 invariant violation — a source that reports Paused
  but starts a burst is flipped to PauseFailed.
* InterruptedLogExtensions — the LogWorkflowInterruptedAsync helper
  that the orchestrator calls when persisting the forensic record.

Tests: 11 new unit tests (DrainOrchestrator parallel-pause +
wait-for-bursts + idempotency + persistence-failure path); 5 new
integration tests (full DI graph resolves, burst-tracking middleware
registers handles end-to-end, no-op drain returns
CompletedWithinDeadline). 100/100 runtime unit tests pass; all
existing tests continue to pass on net8.0/net9.0/net10.0.

Implements 14 of 77 tasks (T032–T045). Subsequent commits add
Interrupted recovery scan (US3), admin endpoints (US2), and
first-party ingress adapters.

* feat(admin-endpoints): add admin endpoints for workflow runtime control

Introduced admin endpoints to manage workflow runtime: `/pause`, `/resume`, `/status`, and `/force` with full authentication and audit logging. Integrated idempotency checks and error handling to ensure reliable runtime control. Added corresponding integration tests for verification.

* fix(workflows-runtime): propagate drain cancellation into running workflows + initialize persisted pause + fix log-comment

Addresses three findings from the PR #7424 code review:

1. **HIGH — Cancellation now propagates into the running workflow.**
   `BurstHandle.Cancel()` previously cancelled only its own linked CTS,
   which the workflow runner never observes (the runner reads from
   `WorkflowExecutionContext.CancellationToken`, captured at context
   construction and not part of the linked chain). On deadline breach
   the orchestrator would persist `Interrupted`, but the workflow
   continued executing and could overwrite the sub-status with whatever
   terminal state it eventually reached.

   Fix: `BurstHandle` accepts an optional cancel callback at construction.
   `BurstTrackingMiddleware` wires it to `context.Cancel()` so the burst's
   cancellation triggers the workflow's own cancellation chain — the
   workflow transitions to `Cancelled` and stops scheduling new
   activities. The orchestrator then awaits `BurstHandle.Disposed` (with
   a 2 s settle timeout) before persisting `Interrupted`, ensuring the
   runner's terminal commit completes BEFORE the orchestrator overwrites
   the sub-status. Race resolved.

   The settle timeout is bounded so a non-cancellable activity (genuinely
   pathological case) does not block drain — on timeout the orchestrator
   logs and proceeds, accepting the runner-clobber for that one
   instance, which the existing timeout-based RestartInterruptedWorkflows
   recovery picks up afterwards.

2. **MEDIUM — Pause persistence is now actually wired.**
   `QuiescenceSignal.InitializePersistedStateAsync` was implemented but
   nothing called it on host startup. A host configured with
   `PausePersistence = AcrossReactivations` would write the persisted
   key on pause, but on subsequent activation the new
   `QuiescenceSignal` instance would never read it, so the runtime would
   resume dispatching despite the operator having paused.

   Fix: `InitializePauseStateStartupTask : IStartupTask` reads the policy
   and calls `InitializePersistedStateAsync` once per activation when the
   policy demands it. Registered in both `WorkflowRuntimeFeature`
   flavours alongside the other graceful-shutdown services.

3. **MEDIUM — Comment in `DrainOrchestrator.PersistInterruptedAsync` no
   longer lies.** The previous comment promised a "synthetic log entry"
   that the next statement (`return`) prevented from being written. The
   comment is now honest about what actually happens: when no instance
   row exists, no log entry is emitted, but the burst metadata is still
   captured in the drain outcome's logged warning so operators have a
   forensic trail.

Tests:
* New unit tests on `BurstRegistry` (now 9, was 6): cancel-callback is
  invoked, callback exceptions are swallowed (drain remains best-effort),
  `BurstHandle.Disposed` completes on dispose.
* Full suites continue to pass: 103/103 runtime unit tests; 247/247
  workflow integration tests.

* fix(workflows-runtime): address PR review feedback + close runner-clobber race + add e2e drain test

Six issues raised in PR #7424 review (one e2e gap, five comments inline):

1. **Runner-clobber race closed via ICommitStateHandler decorator.**
   The previous fix wired `BurstHandle.Cancel()` to `WorkflowExecutionContext.Cancel()`
   so the workflow's cancellation chain fires on deadline breach, but the e2e
   test exposed that `BurstHandle` disposed at the END of the pipeline middleware
   (i.e., BEFORE `WorkflowRunner` calls `commitStateHandler.CommitAsync`). The
   orchestrator's `await handle.Disposed` therefore returned too early, the
   instance row didn't yet exist, and the orchestrator's Interrupted write was
   either a no-op (no row) or got clobbered by the runner's subsequent Cancelled
   commit.

   Fix: `BurstAwareCommitStateHandler` decorates `ICommitStateHandler`. The
   middleware no longer disposes the handle in the success path — it stores
   the handle in `WorkflowExecutionContext.TransientProperties`, and the
   decorator disposes it AFTER `inner.CommitAsync` completes. The exception
   path in the middleware still disposes for safety. Result: the orchestrator's
   await-disposed sequencing now correctly lands the Interrupted write last.

2. **C1: Null-instance log entry.** `DrainOrchestrator.PersistInterruptedAsync`
   now writes a synthetic `WorkflowInterrupted` log entry directly when no
   instance row exists, populating only the fields it knows. Previously the
   forensic trail was lost.

3. **C2: Force endpoint cached-outcome audit.** Added `WasCached` flag to
   `DrainOutcome` (default false). The orchestrator sets it on the cached
   return path (`_previousOutcome with { WasCached = true }`). The force
   endpoint now skips the audit notification when the flag is true, so
   repeated force calls no longer emit spurious `RuntimeForceRequested` events
   (SC-007 idempotency restored).

4. **C3: `StateChanged` raised under lock — deadlock risk closed.**
   `QuiescenceSignal.BeginDrainAsync`/`PauseAsync`/`ResumeAsync` now do their
   transitions under the lock, capture whether a transition occurred, release
   the lock, and only then invoke `RaiseStateChanged`. Subscribers that
   synchronously call back into the signal can no longer deadlock.

5. **C4: Scheduling source name.** Renamed `scheduling.cron` → `scheduling.triggers`
   to honestly reflect the four trigger types the adapter covers (Cron, Timer,
   StartAt, Delay). The name is surfaced verbatim in admin status responses.

6. **C5: Hardcoded Retry-After.** `HttpWorkflowsMiddleware`'s 503 response now
   sets a reason-aware `Retry-After`: 5 s during drain (host is exiting and
   will be replaced shortly), 60 s during administrative pause (indefinite,
   so a longer back-off avoids tight retry loops).

Tests:
* New e2e `DeadlineBreachEndToEndTests` (2 tests): verifies that drain
  against a real running workflow detects the in-flight burst, force-cancels
  it, persists the instance as `Interrupted`, and writes a `WorkflowInterrupted`
  log entry — closing the test gap that hid the cancellation-propagation
  issue identified in the previous review pass.
* Updated `OperatorForceAfterPreviousReturnsCachedOutcome` to assert
  value-equality + the `WasCached` flag instead of reference-equality
  (records use `with` for the cached return path).

Full suites pass: 103/103 runtime unit, 249/249 workflow integration.

* refactor(workflows-api): move runtime admin endpoints into Elsa.Workflows.Api

Per PR review feedback: rather than introducing a new sub-module
(Elsa.Workflows.Runtime.Admin) for the four pause/resume/status/force
endpoints, fold them into the existing Elsa.Workflows.Api project. That
project already references both Elsa.Workflows.Runtime and
Elsa.Api.Common (FastEndpoints) and is the established home for
client-facing workflow APIs — so the admin endpoints belong there.

Changes:
* New folder src/modules/Elsa.Workflows.Api/Endpoints/RuntimeAdmin/ with
  Models.cs and Pause/Resume/Status/Force/Endpoint.cs. Namespaces moved
  from `Elsa.Workflows.Runtime.Admin` → `Elsa.Workflows.Api.Endpoints.RuntimeAdmin`.
* Deleted src/modules/Elsa.Workflows.Runtime.Admin/ entirely and removed
  it from Elsa.sln. The ShellFeature marker class
  (WorkflowRuntimeAdminFeature) is no longer needed — the existing
  WorkflowsApiFeature already discovers FastEndpoints in the Workflows.Api
  assembly.
* No consumer changes: the endpoints sit in the same routes
  (/admin/workflow-runtime/*) and behave identically.

Note on the second architectural point ("update IShellFeature if cleaner"):
the IShellFeature contract is defined in the external CShells NuGet
package, not in this repo, so we cannot add a DeactivateAsync hook
without an upstream CShells change. The current IHostedService.StopAsync
hook continues to work correctly for the host-stop path; per-shell
deactivation would require either a CShells upstream addition or a
separate Elsa-owned shell-feature variant — neither lighter than what we
have today.

Tests: 103/103 runtime unit + 249/249 workflow integration pass.

* feat(common): introduce IsFatal exception extension + apply to drain best-effort catches

Per PR review feedback on the static-analyzer "Generic catch clause"
comments: rather than catching ALL exceptions in best-effort drain code
paths, narrow the swallow to non-fatal exceptions. Process-fatal
conditions (StackOverflowException, AccessViolationException,
SEHException, ThreadAbortException, OutOfMemoryException) propagate so
the host's failure-fast policy can act on them, while normal failures
(InvalidOperationException, IOException, etc.) continue to be logged
and allowed through so a single misbehaving ingress source / activity
cannot abort the overall drain.

Highlights:
* New `Elsa.Common.Extensions.ExceptionExtensions.IsFatal` utility:
  classifies fatal conditions, unwraps reflection-style wrappers
  (TypeInitializationException, TargetInvocationException) before
  classification, and treats InsufficientMemoryException (the
  recoverable OOM subclass) as non-fatal.
* Applied as a `when (!ex.IsFatal())` filter to:
    - BurstHandle.Cancel (cancel callback try/catch)
    - DrainOrchestrator.PauseOneSourceAsync (per-source exception path)
    - DrainOrchestrator.TryForceStopAsync
    - DrainOrchestrator.ForceCancelActiveBurstsAsync (per-burst loop)
    - DrainOrchestrator.PersistInterruptedAsync (orphan log write,
      instance save, log write)
    - DrainOrchestrator.DrainAsync outer catch (existing
      `not InvalidOperationException` filter extended)
    - InterruptedRecoveryScan (per-instance restart loop)

Tests: 7 new unit tests for IsFatal classification (fatal types,
recoverable types, wrapped causes, null tolerance). Full suites:
103/103 runtime unit (incl. 14/14 in Common.UnitTests including new
tests) + 249/249 workflow integration pass.

* feat(workflows-runtime): integrate CShells 0.0.15 lifecycle hooks (IDrainHandler + IShellInitializer)

CShells 0.0.15 ships the lifecycle framework needed for first-class per-shell
graceful shutdown — IDrainHandler / IShellInitializer / IShellLifecycleSubscriber.
This commit bumps the package, migrates Elsa's existing usage of the removed
0.0.14 API, and registers the runtime drain orchestrator + pause-state initializer
through the new primitives.

Highlights:
* `ElsaShellDrainHandler : IDrainHandler` — bridges per-shell drain into
  `IDrainOrchestrator.DrainAsync(DrainTrigger.ShellDeactivation, ct)`. Invoked
  by CShells when a shell enters `ShellLifecycleState.Draining`; the drain
  handler's CancellationToken is signalled when the per-shell deadline elapses,
  so the orchestrator's own deadline-bounded protocol nests cleanly.
  Coexists with the host-stop `DrainOrchestratorHostedService`; the
  orchestrator's `DrainAsync` is idempotent — second invocations log and skip.
* `InitializePauseStateShellInitializer : IShellInitializer` — replaces the
  IStartupTask variant in shell-aware deployments. IShellInitializer fires on
  EVERY shell (re)activation, including reactivations after a reload — exactly
  what FR-028 requires. The IStartupTask remains for IModule consumers where
  there is no shell platform.

Migrations (CShells 0.0.14 → 0.0.15 breaking changes):
* `ActivateShellTenants`: was `IShellActivatedHandler` + `IShellDeactivatingHandler`,
  now `IShellInitializer` + `IDrainHandler`.
* `MultitenancyFeature`: registrations updated to the new transient interface,
  `using CShells.Hosting` → `using CShells.Lifecycle`.
* `Reload/Endpoint`, `ReloadAll/Endpoint`: `IShellManager` → `IShellRegistry`,
  `ReloadShellAsync` → `ReloadAsync` (returns `ReloadResult` with `Error`),
  `ReloadAllShellsAsync` → `ReloadActiveAsync` (returns
  `IReadOnlyList<ReloadResult>` with per-shell errors aggregated into 503).

Build + restore:
* `Directory.Packages.props`: all CShells.* packages bumped to 0.0.15.
* `NuGet.Config`: added `cshells-feedz` source
  (https://f.feedz.io/sfmskywalker/cshells/nuget/index.json) and split the
  package-source-mapping pattern into `CShells` (exact) + `CShells.*`
  (prefix). Single-pattern `CShells*` does NOT match correctly under
  PackageSourceMapping.

Tests: 103/103 runtime unit + 249/249 workflow integration pass on the new
package version.

* refactor(workflows-runtime): apply PR #7424 review feedback

Consolidates the architectural fixes asked for during /review:

- Extract IWorkflowRuntimeAdminService to back the four /admin/workflow-runtime endpoints with a single domain service; thin Pause/Resume/Status/Force endpoints to delegating shells.
- Remove StateChanged C# event from IQuiescenceSignal (Constitution VII: no external subscribers existed; mediator was suggested as the alternative if/when it's needed).
- Promote InitializePersistedStateAsync to IQuiescenceSignal, dropping the concrete-cast in both InitializePauseStateStartupTask and InitializePauseStateShellInitializer.
- Invert ingress-source DI to Lazy<IEnumerable<IIngressSource>> to break the cycle through IQuiescenceSignal; ingress adapters take the signal directly via primary constructor.
- Replace Guid.NewGuid().ToString("N") with IIdentityGenerator in InterruptedLogExtensions and DrainOrchestrator.
- Switch admin-audit timestamps to ISystemClock in WorkflowRuntimeAdminService.
- Make GracefulShutdownOptions.StimulusQueueMaxDepthWhilePaused nullable (null = unlimited).
- Rename RuntimeForceRequested → RuntimeForceDrainRequested.
- Apply IsFatal exception filter to drain best-effort catches.
- Rename IBurstRegistry.EnumerateActive → ListActiveBursts.
- Refresh "Phase X" comments to user-story (USx) references.
- Delete unused IngressAttributionExtensions, IngressSourceServiceCollectionExtensions, IngressSourceRegistrationOptions.
- Migrate Elsa.Shells.Api.Tests to CShells 0.0.15 IShellRegistry / ReloadResult surface.

* test(graceful-shutdown): apply IsFatal filter to deadline-breach test catch

Aligns the test scaffolding's swallow-everything catch with the project standard introduced in c00eee80c so the analyzer no longer flags the bare `catch` clause. The semantics are unchanged — non-fatal exceptions (OCE, TimeoutException, workflow exceptions) are still acceptable test outcomes.

* fix(workflows-runtime): close IngressSourceRegistry first-access race + spelling

Replaces the non-atomic `_entries.Count > 0` early-return guard in
EnsureMaterialized with a double-checked lock against a volatile
`_materialized` flag, so concurrent first callers can no longer both
iterate the source factory and crash one of them with a "Duplicate ingress
source registration" InvalidOperationException. Adds a regression test that
launches 16 readers behind a TaskCompletionSource gate and asserts every
reader observes the full source set without throwing.

Also flips the British spellings introduced in this PR's scope to American
English (materialize/behavior) — project convention going forward.

* docs(constitution): require American English for new code (v1.0.1)

Adds a "Spelling & language" bullet under principle III (Convention-Driven Design): every newly-introduced symbol, comment, identifier, error message, XML doc, commit message, and Speckit artifact uses American English. Established public API symbols (e.g. WorkflowSubStatus.Cancelled) are not renamed retroactively. PATCH bump because this is a clarification of an existing principle, not a new principle.

* fix(graceful-shutdown): apply PR #7424 review feedback round 2

Two P1 findings from Greptile:

1. DrainOrchestrator.ForceCancelActiveBurstsAsync was sequential — each
   burst was cancelled, awaited up to ForceCancelSettleTimeout (2 s), and
   persisted before the next burst's Cancel() ran. Total wall time was
   O(N × 2 s) and bursts 2..N kept executing at full speed during prior
   bursts' settle waits, defeating the intent of force-cancel under
   concurrency.

   Refactored to three phases:
   - Phase A — cancel every handle synchronously (cheap CTS.Cancel calls)
     so all runners observe cancellation simultaneously.
   - Phase B — await every Disposed signal in parallel under a single
     shared ForceCancelSettleTimeout. Total wall time bounded regardless
     of N.
   - Phase C — persist Interrupted for each handle sequentially (keeps
     DbContext usage single-threaded; per-handle work is small).

   Per-phase failures are caught with !ex.IsFatal() and logged so a single
   misbehaving handle doesn't abort the rest of the batch.

2. ShellFeatures/WorkflowRuntimeFeature.ConfigureServices was missing the
   IWorkflowRuntimeAdminService registration that Features/WorkflowRuntimeFeature
   already had. Any CShells deployment that includes the Pause / Resume /
   Status / Force admin endpoints (in Elsa.Workflows.Api) would throw
   InvalidOperationException at endpoint construction. Added the singleton
   alongside the other graceful-shutdown registrations with a comment
   pointing out the symmetry with the IModule path.

17/17 graceful-shutdown integration tests pass; 103/103 runtime unit tests pass.

* Potential fix for pull request finding 'CodeQL / Untrusted Checkout TOCTOU'

Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com>

* fix(ci): harden greploop.yml against CodeQL Actions findings

CodeQL flagged 12 findings on .github/workflows/greploop.yml after the
prior commit (c08183a3c) addressed an earlier round. Two distinct issue
classes remain:

1. Code injection (× ~10): step-output values
   (steps.pr_head.outputs.head_sha / head_repo_owner / head_repo_name /
   head_ref) and inputs.pr_number were interpolated directly into shell
   `run:` blocks via `${{ ... }}`. Because PR author controls the branch
   name and the manual-dispatch input, those values can carry shell
   metacharacters. Standard fix: route every such interpolation through
   an `env:` block on the step, then reference $VAR inside the script.
   Applied to the Resolve, Resolve PR head metadata, and Checkout PR
   branch steps.

2. Untrusted Checkout TOCTOU + Checkout of untrusted code in trusted
   context: the workflow runs on `issue_comment` (a privileged trigger)
   and checks out PR-author code. Mitigations stacked here:
   - Author-association gate already restricts the trigger to OWNER /
     MEMBER / COLLABORATOR (existing).
   - Step-output values now travel via env vars (above).
   - Resolve step rejects pr_number that isn't ^[0-9]{1,10}$ — so
     downstream `gh pr view` and the prompt argument can't be hijacked.
   - Checkout step now validates HEAD_SHA matches ^[0-9a-f]{40}$ and the
     repo owner/name match ^[A-Za-z0-9_.-]+$ before either reaches a
     URL or a git command.
   - Existing TOCTOU guard preserved: re-fetch head SHA at checkout
     time and abort if it changed since the initial resolve.

These match the canonical "Securing your GitHub Actions workflows"
patterns recommended by CodeQL.

No functional change to greploop's runtime behaviour.

* fix(graceful-shutdown): drop [SingleNodeTask] from InitializePauseStateStartupTask

Greptile P1: [SingleNodeTask] gates the task to a single cluster winner via
distributed lock, but IQuiescenceSignal is a singleton scoped to each node's
DI container — each node holds its own in-memory QuiescenceState. With the
attribute, only the winning node restored the persisted pause; every other
node started with QuiescenceReason.None and accepted new work, silently
defeating PausePersistence = AcrossReactivations.

Removed [SingleNodeTask] (and the corresponding using) so the task runs on
every node. Expanded the doc <remarks> to call out the per-node requirement
and point at the shell-aware counterpart (InitializePauseStateShellInitializer)
which is correctly per-node by virtue of being an IShellInitializer.

17/17 graceful-shutdown integration tests still pass.

* chore(deps): bump CShells 0.0.15 → 0.0.17

0.0.17 ships our blueprint-aware-routing PR (valence-works/cshells#93) plus
four follow-up fixes the maintainer added on top:

- e56ebd8 — PreWarmShells removed entirely; ShellMiddleware now does
  cold-start endpoint matching (re-runs endpoint resolution after lazy
  activation so the very first request to a cold shell hits its endpoint).
- cbe5ee2 — GetCandidateSnapshot returns a bounded ShellRouteCandidateSnapshot
  with accurate total counts; sensitive-data redaction in routing logs;
  DefaultShellRouteIndex implements IDisposable.
- cd7d4f5 — Last-good snapshot served on rebuild failure (the deferred
  Copilot review concern); root-path fallback when path-by-name misses.
- c3679d9 — Cold-start endpoint matching respects inline route constraints;
  path-name convention tightening; dead duplicate-detection cleanup.

Net effect for elsa-core:
- Cold blueprints serve their first request via lazy activation, with
  endpoints correctly resolved post-activation.
- Reloaded shells re-activate and serve on the next matched request.
- Non-name-mode routing keeps serving the previous snapshot during a
  transient blueprint-provider outage.
- No need to call PreWarmShells from Elsa.ModularServer.Web — removed.

The only API removal that touches elsa-core is PreWarmShells. No code
references IShellRouteIndex / ShellRouteCriteria / GetCandidateSnapshot
directly, so the API-shape changes in cbe5ee2 don't ripple here.

* fix(graceful-shutdown): persist Interrupted under non-drain bounded token

Greptile P? finding on the prior force-cancel two-phase fix: Phase B's
inner catch on OperationCanceledException ("drain CT fired — proceed to
persist anyway") was a lie in practice. Phase C immediately passed the
same already-cancelled drain token into PersistInterruptedAsync; the
first DB call (instanceStore.FindAsync) observed the cancellation and
threw OperationCanceledException; the outer non-fatal Exception filter
swallowed it and only logged an error. Net effect: on host shutdown
deadline breach, every burst after cancellation could fail to be
persisted as Interrupted, leaving instances in an unrecovered executing
state.

Phase C now creates a per-handle CancellationTokenSource bounded to a
new PersistInterruptedTimeout (5 s) that is NOT linked to the drain CT.
Each persist gets up to 5 s to land the row update + forensic log entry
even after the drain CT has fired. The bound prevents a stuck DB from
hanging shutdown indefinitely (per-handle worst case is small; total
Phase C upper bound is N × 5 s, but typical persists are millisecond
scale).

Comment expanded to call out why the persist token is independent of
the drain token, so the rationale doesn't drift again.

17/17 graceful-shutdown integration tests still pass.

The three IIngressSource implementations that ship with this PR
(InternalBookmarkQueueIngressSource, HttpTriggerIngressSource,

those were verbatim copies of each other:

- ctor signature `(IQuiescenceSignal signal)`
- `PauseTimeout => TimeSpan.FromMilliseconds(50)`
- `CurrentState => signal.IsAcceptingNewWork ? Running : Paused`
- `PauseAsync` / `ResumeAsync` returning `ValueTask.CompletedTask`

The shared trait is that none of them does any work at pause time —
the actual pause enforcement lives in another layer
(`HttpWorkflowsMiddleware` short-circuits to 503,
`BookmarkQueueProcessor` consults the signal at the top of each
invocation, scheduled triggers dispatch through the bookmark queue and
inherit that behaviour transitively). The IIngressSource adapter is
purely diagnostic: it makes the source visible in
`DrainOutcome.Sources` and the admin status endpoint.

Extracted that pattern into `PassiveIngressSource` (abstract base in
`Elsa.Workflows.Runtime.IngressSources`). Subclasses now provide only
`Name`; `PauseTimeout` is `virtual` with a 50 ms default; everything
else is fixed by the base. The three concretes drop from ~25 lines to
~12 lines each.

The base's XML `<remarks>` calls out when to use it ("your component
already cooperates with IQuiescenceSignal at its hot path") and when
to implement IIngressSource directly ("the source owns concrete
pause/resume behaviour — e.g. a message-queue consumer that calls
Pause() on its underlying client"), so future contributors don't
mis-extend the base for sources that need real work at pause time.

No behavioural change. 18 graceful-shutdown integration + 39 runtime
unit tests still pass.

* refactor(graceful-shutdown): align IIngressSource name to singular

The three IIngressSource names were inconsistent:

  http.trigger                       (singular)
  internal.bookmark-queue-worker     (singular)
  scheduling.triggers                (PLURAL — outlier)

The plural slipped in when addressing Greptile's earlier comment to
avoid `scheduling.cron` (which would imply Cron-only coverage). The
right move was to pick a generic word and stay singular like the rest
of the suite — the suite's mental model is "the X source", one
instance per registry slot, regardless of how many triggers or items
it dispatches internally.

Renamed to `scheduling.trigger`. The `<remarks>` block keeps the
"covers Cron, Timer, StartAt, Delay" explanation and now also
explicitly notes the singular convention so future contributors don't
re-pluralize.

Zero test fallout — the literal "scheduling.triggers" only appeared in
the source file itself. Tests of the other two sources all use
singular forms.

* refactor(runtime-admin): rename Force endpoint to ForceDrain

"Force" alone is meaningless out of context — force what? — and it
sits oddly next to the verb-named siblings Pause / Resume / Status.
The matching admin service method is already IWorkflowRuntimeAdminService.
ForceDrainAsync, so ForceDrain is the natural pair.

Renamed:
- src/modules/Elsa.Workflows.Api/Endpoints/RuntimeAdmin/Force/        → ForceDrain/
- namespace ...Endpoints.RuntimeAdmin.Force                            → ...ForceDrain
- class ForceEndpoint                                                  → ForceDrainEndpoint
- class ForceRequest                                                   → ForceDrainRequest
- class ForceResponse                                                  → ForceDrainResponse
- route  POST /admin/workflow-runtime/force                            → /force-drain

Zero external references — no tests, docs, or OpenAPI clients used the
old symbols or the old route literal, so this is a contained pre-ship
rename. Directory move went through `git mv` so commit history follows
the file.

17/17 graceful-shutdown integration tests still pass.

* fix(ci): correct formatting in checkout step within greploop.yml

Adjusted indentation of environment variables in the checkout step for improved consistency and readability.

* fix(ci): repair malformed Checkout repository step in greploop.yml

The step accumulated stray env keys, an extra `uses:`, and bash commands
that didn't belong inside it (line 65 onward), causing a YAML parse
error on push. The valid structure has two distinct checkout steps:

  - Checkout repository  : actions/checkout@v4 with fetch-depth: 0
  - Checkout PR branch   : env: + run: with SHA validation + git fetch
                            + git checkout --detach

The PR-branch step (line 78+) was already correct and unchanged. This
fix restores the first step to its intended single-purpose shape (just
checks out the workflow file's commit so the greploop skill is on disk
before the run-greploop step uses it).

No functional change to runtime behaviour or to the security posture
established in the prior hardening commit (0db4ca23e). The PR-branch
checkout still validates HEAD_SHA / HEAD_REPO_OWNER / HEAD_REPO_NAME
shape before they reach a URL or git command.

* fix(ci): remove literal `${{ }}` from greploop.yml comment

GitHub Actions parses `${{ ... }}` workflow expressions across the entire
YAML file, including inside `run:` script comments. The comment that
explained the env-var hardening pattern contained the literal sequence
`${{ }}` (with a space, intended as an English-language description),
which the expression parser rejected as "An expression was expected"
(line 81 col 14).

Reworded the comment to describe the substitution form in prose without
the literal token sequence. Functional behaviour unchanged.

* refactor(graceful-shutdown): rename burst → execution cycle

The graceful-shutdown work introduced "burst of execution" as a
first-class domain concept. The term arrived without rationale and
isn't standard in the workflow-engine domain. Renamed to
"execution cycle" — reads more naturally as the loop-with-commit unit,
is more idiomatic in workflow vocabulary, pairs cleanly with the
existing WorkflowExecutionContext, and avoids collisions with Elsa's
existing terms (Run, Execution, Dispatch, Invocation, Stimulus, Step).

Renamed types
- IBurstRegistry              → IExecutionCycleRegistry
- BurstRegistry               → ExecutionCycleRegistry
- BurstHandle                 → ExecutionCycleHandle
- BurstTrackingMiddleware     → ExecutionCycleTrackingMiddleware
- BurstAwareCommitStateHandler → ExecutionCycleAwareCommitStateHandler

Renamed members
- BeginBurst                          → BeginCycle
- ListActiveBursts                    → ListActiveCycles
- BurstHandleKey constant + value     → ExecutionCycleHandleKey
- ActiveBurstCount (IQuiescenceSignal,
  RuntimeAdminStatus, StatusResponse) → ActiveExecutionCycleCount
- WaitForBurstsAsync (private)        → WaitForCyclesAsync
- ForceCancelActiveBurstsAsync (priv) → ForceCancelActiveCyclesAsync
- UseBurstTracking                    → UseExecutionCycleTracking
- DrainOutcomeDto.BurstsForceCancelledCount → ExecutionCyclesForceCancelledCount
- _burstRegistry / burstRegistry      → _cycleRegistry / cycleRegistry

Backwards-compatibility preservation (the only persisted JSON key)
- WorkflowInterruptedPayload.BurstDuration property → ExecutionCycleDuration
  with [JsonPropertyName("BurstDuration")] so the persisted JSON wire
  key stays "BurstDuration" forever. Pre-merge testers' log records
  still deserialise correctly. The contract test on
  WorkflowInterruptedPayloadContractTests still asserts the wire key
  "BurstDuration" appears in the serialised JSON — confirms the
  guarantee is enforced.

Other unstructured surfaces
- WorkflowExecutionLogRecord.Message text "Workflow burst was force-
  cancelled..." now says "Workflow execution cycle was force-cancelled
  ..." for new records. Old rows keep their old text — purely cosmetic
  free-text field.
- Structured log placeholder {BurstId} in DrainOrchestrator log lines
  → {ExecutionCycleId}.
- Lowercase prose / XML doc comments updated throughout.

Test renames
- BurstRegistryTests          → ExecutionCycleRegistryTests
- BurstTrackingMiddlewareTests → ExecutionCycleTrackingMiddlewareTests
- Test method names + DisplayName strings updated.

Spec docs (specs/002-graceful-shutdown/) updated to match the new
vocabulary; the historical task records in tasks.md keep the old names
as-is to preserve the audit trail of what was originally built.

Verification
- dotnet build: clean across net8.0 / net9.0 / net10.0.
- 103/103 Elsa.Workflows.Runtime.UnitTests pass.
- 17/17 GracefulShutdown integration tests pass.
- 4/4 WorkflowInterruptedPayloadContractTests pass — confirms the
  "BurstDuration" JSON wire-key preservation is intact.

No changes to migrations or DB column names — confirmed via grep.

* fix(ci): give greploop.yml gh-cli a repo context before checkout

The "Resolve PR head metadata" step runs `gh pr view` before
actions/checkout, so there is no `.git` directory and gh's "current
repo" detection fails with `fatal: not a git repository`. The
prior commits to this file masked the runtime failure because the
workflow itself was YAML-invalid — once it became valid, the
workflow_dispatch trigger surfaced this real-world execution bug.

Set GH_REPO=${{ github.repository }} on both `gh pr view` steps. The
gh CLI honours GH_REPO as an explicit repo override, so it no longer
needs git context. Same fix on the "Checkout PR branch" validation
call which also uses gh pr view before the manual fetch.

The error reported as "Invalid workflow file: ... (Line 81 Col 14)"
on PR #7424 was stale from commit ed580682a (which had the bad
comment with literal `${{ }}`); commit 3a8ad0d08 fixed the YAML, but
because greploop's `if:` condition only matches workflow_dispatch /
issue_comment events, push events on later commits were skipped
without re-running validation, so the GitHub UI kept showing the
old error. A workflow_dispatch run on the current SHA now passes
validation and reaches "Resolve PR head metadata", which is what
this commit fixes.

* fix(graceful-shutdown): wire IngressPauseTimeout option to drain orchestrator

GracefulShutdownOptions.IngressPauseTimeout was documented as "Default
per-ingress-source pause timeout" but DrainOrchestrator.PauseOneSourceAsync
read source.PauseTimeout directly and never consulted the option. The
configured value was silently ignored — operators who set
GracefulShutdownOptions:IngressPauseTimeout = 10s were getting whatever
each source's hardcoded value was (50 ms for the three PassiveIngressSource
subclasses we ship), with no way to tune it globally.

Precedence (per the spec's intent of "overridable at registration and by
configuration"):

  1. Per-source positive value wins (source.PauseTimeout > Zero).
  2. Otherwise fall back to the configured GracefulShutdownOptions.
     IngressPauseTimeout default.
  3. Resolved value is capped at the overall drain deadline so a single
     misbehaving source cannot exceed the host's shutdown budget.
  4. 1 ms safety floor remains so a misconfigured zero default still
     produces a non-zero CancelAfter.

Changes:

- DrainOrchestrator.PauseOneSourceAsync — adds the precedence above with
  a comment block explaining each step.
- IIngressSource.PauseTimeout — XML doc clarifies the Zero-defers-to-
  config semantics.
- GracefulShutdownOptions.IngressPauseTimeout — XML doc says it's the
  fallback when the source returns Zero; <remarks> spells out the
  precedence and the overall-deadline cap.
- PassiveIngressSource.PauseTimeout — virtual property now returns Zero
  (was 50 ms). The three shipped subclasses (HttpTriggerIngressSource,
  ScheduledTriggerIngressSource, InternalBookmarkQueueIngressSource)
  consequently defer to the configured default — flipping the wire-up
  bug from "configured value silently ignored" to "configured value
  honoured by default for passive sources". Passive subclasses that
  want a specific value can still override.

103/103 runtime unit + 17/17 graceful-shutdown integration tests pass.

* refactor(graceful-shutdown): rename IInterruptedRecoveryScan → IInterruptedRecoveryScanner

The interface had a single verb-method (`ScanAndRequeueAsync`) and its
XML doc described what it *does* ("Scans the workflow instance store
for instances..."). That's an agent role — a scanner that performs a
scan — but the noun-shaped name `IInterruptedRecoveryScan` read as
"the scan itself", which is misleading because the scan results /
event are not first-class types in the codebase.

Renamed to `IInterruptedRecoveryScanner` / `InterruptedRecoveryScanner`
to match the existing `-er` convention in this codebase (Restarter,
Generator, Resolver, etc.). The method stays `ScanAndRequeueAsync` —
the scanner *performs* a scan-and-requeue.

Also renamed the constructor parameter `scan` → `scanner` in
RecoverInterruptedWorkflowsStartupTask, and the local variable `scan`
→ `scanner` in InterruptedRecoveryIntegrationTests, so the "scanner
does the scan" mental model is consistent throughout.

Surface impact (all internal — no API or persistence touch points):
- 2 source files renamed via git mv (interface + implementation)
- 1 test file renamed (InterruptedRecoveryScanTests → ScannerTests)
- DI registrations in both Features/ and ShellFeatures/ WorkflowRuntimeFeature
- 1 startup-task constructor parameter
- Spec doc references under specs/002-graceful-shutdown/

103/103 runtime unit + 17/17 graceful-shutdown integration tests pass.

* refactor(graceful-shutdown): extract DrainTriggerExecutor

ElsaShellDrainHandler (CShells IDrainHandler) and
DrainOrchestratorHostedService (.NET IHostedService.StopAsync) inlined
near-identical try/catch/log shapes around IDrainOrchestrator.DrainAsync:

  - call DrainAsync(<trigger>, ct)
  - branch on outcome: DeadlineExceeded/AbortedByUnhandledException →
    Warning, otherwise Information
  - catch InvalidOperationException (parallel-drain rejected by the
    orchestrator) → log Information and swallow

The two had already drifted: host-stop's success log omitted the
paused/waited durations the shell-handler version included, and the
"skipped" message disagreed on the trigger label ("Host-stop drain
skipped" vs "Shell drain skipped"). Centralised the shape in a small
internal static helper so the two — and any future trigger source —
stay uniform.

Both call sites collapse to a single line. Net diff drops 22 lines from
the two consumers and adds a 25-line helper that they both delegate to.
The unified log copy now consistently includes paused/waited durations
on the success path and uses the caller-supplied contextLabel
("Shell drain", "Graceful drain") in all three messages so operators
can attribute log entries by trigger source.

Files:
- src/modules/Elsa.Workflows.Runtime/Services/DrainTriggerExecutor.cs (new)
- src/modules/Elsa.Workflows.Runtime/Lifecycle/ElsaShellDrainHandler.cs
- src/modules/Elsa.Workflows.Runtime/HostedServices/DrainOrchestratorHostedService.cs

103/103 runtime unit + 17/17 graceful-shutdown integration tests pass.

* refactor(workflows-runtime): drop redundant DrainOrchestratorHostedService from CShells path

In CShells deployments, host stop already drives drain via CShellsStartupHostedService → IDrainHandler →
ElsaShellDrainHandler, scoped per shell (FR-027). The additional .AddHostedService<DrainOrchestratorHostedService>()
in ShellFeatures/WorkflowRuntimeFeature was firing a second non-force DrainAsync that the orchestrator rejected
with InvalidOperationException — silently swallowed by DrainTriggerExecutor, but logged on every host stop and
semantically muddled (IHostedService is host-level, not per-shell).

Keep the registration on the IModule path (Features/WorkflowRuntimeFeature) where there is no shell platform
and host-stop is the only available drain trigger. Update ElsaShellDrainHandler XML docs to reflect the now-clean
single-trigger model in CShells.

* fix(workflows-runtime): always dispose ExecutionCycleHandle in tracking middleware

Previously the success path relied on ExecutionCycleAwareCommitStateHandler to dispose the handle after the
runner's commit completed. If a custom dispatcher or test double exited the pipeline without invoking commit
(by design or by accident), the handle stayed registered, IExecutionCycleRegistry.ActiveCount never reached
zero, and drain spun in WaitForExecutionCyclesAsync until the deadline fired — incorrectly force-cancelling
instances that had already finished cleanly.

Collapse the existing try/catch(rethrow) into try/finally so the middleware itself disposes the handle for
both exception and commit-elided paths. Disposal remains idempotent via the ExecutionCycleHandle._disposed
Interlocked guard, so the normal-path dispose by ExecutionCycleAwareCommitStateHandler is a harmless no-op.

Adds an integration regression test that drives the middleware with a stub Next that returns without invoking
commit and asserts ActiveCount returns to zero.

* fix(workflows-runtime): serialize QuiescenceSignal pause-state persistence

Both PauseAsync and ResumeAsync used to release the inner lock before issuing the persistence I/O. A rapid
Pause → Resume sequence could leave the persisted state inconsistent: PauseAsync's slow SaveAsync could land
AFTER ResumeAsync's DeleteAsync, leaving the key present in the store while in-memory state was None. On host
restart, InitializePersistedStateAsync would find the stale key and start the runtime in the paused state
the operator had already cancelled.

Introduce a dedicated SemaphoreSlim that serializes persistence I/O, with each I/O re-reading the live
in-memory state inside the semaphore. N racing Pause/Resume calls now produce N serialized writes, each
reflecting the most recent in-memory transition — so the final persisted state always matches final
in-memory state.

Adds a regression test that gates SaveAsync, races a Resume behind it, and asserts the store is empty after
both complete.

* refactor(workflows-runtime): use 'using var' for ExecutionCycleHandle in tracking middleware

HandleReleasedWhenCommitIsElided continues to validate the leak-free property.

* fix(workflows-runtime,api): proper 409 conflict shape + shell-scoped pause-persistence key

ForceDrain endpoint: the 409 path returned `new ForceDrainResponse()` whose `Outcome` was null at runtime
despite the `= null!` annotation, so any strongly-typed client deserializing the conflict body and reading
`Outcome.OverallResult` got an NRE. Switch to the existing `ConflictResponse` shape with
`Code = "DrainInProgress"` and the current runtime status. Routed via HttpContext.Response.WriteAsJsonAsync
because Send.ResponseAsync is constrained to the endpoint's TResponse and cannot send a sibling DTO.

QuiescenceSignal persistence key: the DI-registered `IQuiescenceSignal` was constructed with
`shellName = null` (DI doesn't inject `string?` defaults), so every shell shared the key
`elsa.quiescence.pause.default`. In a CShells multi-shell deployment under
PausePersistencePolicy.AcrossReactivations this caused cross-shell contamination — pausing shell A would
re-pause shell B on its next activation. Replace the simple AddSingleton<IQuiescenceSignal,...> registration
in ShellFeatures/WorkflowRuntimeFeature with a factory that injects `CShells.ShellSettings` and forwards
`Settings.Id` as the shell name. The IModule registration is unchanged (no shell platform; null shellName
remains correct there).

Adds a unit regression test that two QuiescenceSignal instances with different shellNames write to disjoint
persistence keys and never to the legacy "default" key.

* test(quiescence): use TryGetValue for ContainsKey+indexer assertions

Combines existence check and value retrieval into a single dictionary lookup, addressing the code-quality

* fix(workflows-runtime): decouple QuiescenceSignal persistence from caller cancellation

PersistAsync used to forward the caller's CancellationToken to both _persistenceMutex.WaitAsync and the
store I/O. If an HTTP request was cancelled between the in-memory transition (already committed under
_sync) and the persistence call, the I/O was silently skipped — leaving AdministrativePause set in memory
with no persisted record. The idempotent fast-path on subsequent PauseAsync calls (transitioned == false)
meant no retry would happen, so on host restart InitializePersistedStateAsync would find no key and the
runtime would come back unpaused, defeating PausePersistencePolicy.AcrossReactivations.

Drop the parameter from PersistAsync entirely; use CancellationToken.None for both the semaphore wait and
the store I/O. The in-memory transition is already committed by the time PersistAsync runs, so persistence
must complete to keep the store consistent with memory. The public PauseAsync/ResumeAsync methods still
accept a CancellationToken (interface contract) — it just no longer reaches the persistence layer.

Adds a regression test that calls PauseAsync with a pre-cancelled token and asserts both in-memory pause
and the persisted key land correctly.

* fix(workflows-runtime,api,docs): apply Copilot review feedback batch

Code:
- DrainOrchestrator.TryForceStopAsync now bounds force-stop with the *remaining* drain budget
  (deadlineAt - now), not the full overall TimeSpan. A per-source pause that already burned the
  shutdown window can no longer get another full deadline's worth of force-stop runway.
- DrainOrchestrator catch filter narrowed: drop `ex is not InvalidOperationException` exclusion.
  The "drain already in progress / completed" IOEs are thrown outside the protocol's try block,
  so they bubble out without entering this handler. Any IOE that lands here is incidental
  (e.g., from a store inside the drain) and should now be captured into the outcome rather
  than escaping the whole drain.
- ResumeEndpoint 409 path now returns the discriminated ConflictResponse shape (matching
  ForceDrain) instead of a plain StatusResponse. Routed via HttpContext.Response.WriteAsJsonAsync
  because Send.ResponseAsync is constrained to TResponse.
- Conflict codes aligned to kebab-case across both endpoints to match the contract spec
  (`runtime-draining` and `drain-in-progress`).

Spelling sweep — American English per constitution v1.0.1 III:
- DrainOrchestrator.cs: "serialised" → "serialized"
- WorkflowInterruptedPayload.cs: "serialised" / "deserialise" → "serialized" / "deserialize"
- PassiveIngressSource.cs: "behaviour" → "behavior"
- DeadlineBreachEndToEndTests.cs: "serialisable" → "serializable"
- specs/002-graceful-shutdown/quickstart.md: "behaviour" → "behavior"
- specs/002-graceful-shutdown/checklists/requirements.md: "behaviour" → "behavior"

Doc/contract alignment:
- quickstart.md: force route corrected from /force to /force-drain.
- quiescence-signal.md: removed StateChanged event from contract (interface doesn't define it);
  corrected persistence section to describe InitializePersistedStateAsync via shell initializer
  / startup task rather than constructor read; added the per-shell key discriminator.

* fix(workflows-runtime): correct DI lifetimes for ExecutionCycleTrackingMiddleware and WorkflowRuntimeAdminService

Two strict-DI-validation failures surfaced in tests using BuildServiceProvider with validate-on-build:

1. ExecutionCycleTrackingMiddleware was registered as AddSingleton<>, but its constructor takes
   WorkflowMiddlewareDelegate next — supplied by the workflow execution pipeline builder via
   UseMiddleware<>(), not from DI. The registration was both unused (no consumer resolves it through
   the container) and broken (DI fails to construct it because next is unregistered). Removing both
   registrations.

2. IWorkflowRuntimeAdminService was registered as AddSingleton<> but depends on the scoped
   INotificationSender (mediator) — captive-dependency violation. All consumers (Pause/Resume/
   Status/ForceDrain endpoints) are FastEndpoints, which are scoped per request, so AddScoped is
   the correct alignment. The other deps (IQuiescenceSignal / IIngressSourceRegistry /
   IDrainOrchestrator / ISystemClock) are singletons and resolve fine from a scoped consumer.

* fix(workflows-runtime): restore commit-handler-only success disposal + true Cancel idempotency

Two issues raised by Copilot's latest review on commit 32a9c0519:

1. ExecutionCycleTrackingMiddleware was disposing the handle at the end of InvokeAsync (via `using var`),
   but WorkflowRunner runs commit AFTER the pipeline returns (WorkflowRunner.cs:235). That meant the handle
   was disposed BEFORE the runner's terminal commit, and the drain orchestrator's
   `await handle.Disposed` would unblock too early — reintroducing the runner-clobber race the original
   design protected against (see ExecutionCycleAwareCommitStateHandler XML doc).

   Revert to the original shape: only dispose on exception path. ExecutionCycleAwareCommitStateHandler
   remains the SOLE success-path disposer, running in its finally block AFTER the inner commit lands.
   The earlier "leak when commit is elided" concern was a non-issue in production (the standard runner
   always commits); the buggy `HandleReleasedWhenCommitIsElided` test that specified the wrong contract
   is removed. The existing `ActiveCountReturnsToZero` test (which uses the real runner end-to-end)
   already verifies success-path disposal.

2. ExecutionCycleHandle.Cancel() was documented as idempotent but only short-circuited via the
   _disposed flag. Repeated Cancel() calls before Dispose could trigger the cancel callback multiple
   times — easy to accidentally fire non-idempotent cancellation side effects more than once. Add an
   Interlocked _cancelled guard so callback + CTS cancellation run at most once. Existing test that
   documented the leaky behavior is updated to assert the now-truly-idempotent contract.

Refactor Workflow Runtimes (#5444)
* Add caching to workflow runtime and workflow management stores

The update introduces caching to workflow runtime and workflow management stores to enhance performance. This is achieved by adding decorators for several stores, which cache records to reduce database fetches. Additionally, a signaler for change tokens allows for cache invalidation when changes occur. The MemoryCache feature has also been updated to include Scrutor for decoration and the caching duration can be configured through the new CachingOptions class.

* Refactor WorkflowsMiddleware for HTTP Endpoint bookmarks and triggers

The WorkflowsMiddleware has been extensively refactored to handle HTTP Endpoint bookmarks and triggers. This involves breaking down the InvokeAsync method by extracting parts of its functionality into separate helper methods such as FindTriggersAsync and FindBookmarksAsync. Moreover, Assist with authorization checks, workflow execution within request timeout, and handling of workflow faults has been improved to be more efficient and clearly segmented.

* Update HTTP endpoint authorization to use Workflow context

The authorization process in the AuthenticationBasedHttpEndpointAuthorizationHandler class has been updated to use the Workflow context instead of the WorkflowInstanceId string. The AuthorizeHttpEndpointContext model has been correspondingly changed to include a Workflow property, thereby strengthening the link between authorization and specific workflows.

* Add FindAsync methods to trigger and bookmark stores

The code adjustments add new FindAsync methods to the trigger and bookmark store contracts as well as all their concrete implementations (MongoDb, Memory and EFCore). These methods support fetching the first record matching a given filter. The adjustments also include minor syntax improvements and the addition of [UsedImplicitly] attributes where needed.

* Refactor WorkflowsMiddleware for improved workflow handling

The code was refactored to simplify the flow of handling workflows in the WorkflowsMiddleware class. Specifically, the methods to start and resume a workflow have been extracted to improve code readability. Further, handleErrorMiddlewares was also updated to better manage instances where no valid workflows or base paths are found.

* Add caching functionality to WorkflowsMiddleware

Added IMemoryCache usage in the WorkflowsMiddleware to cache lookup results for workflows and their associated triggers. This will reduce the number of database operations required when searching for workflows, thus improving performance. The cache is maintained for one minute before it is refreshed.

* Implement dynamic cache duration for workflows

The code has been updated to have a dynamic cache duration for the workflows instead of a hardcoded one minute. By using the CachingOptions service, the cache duration can now be set in the configuration making it more flexible and adaptable to different performance needs.

* Add HttpWorkflowsCacheManager for caching HTTP workflows

This commit includes the implementation of IHttpWorkflowsCacheManager for caching of HTTP workflows. New handlers have been added to invalidate cache on workflow updates. Additionally, WorkflowsMiddleware has been renamed to HttpWorkflowsMiddleware.

* Refactor workflow trigger handling and caching

The refactoring includes deletion of `IndexWorkflowTriggersHandler.cs` and creation of `IndexTriggers.cs` thus revising the workflow trigger indexing approach. Also, revamped the `ITriggerIndexer` interface which now handles deletion of triggers with specific workflow and filter. Furthermore, the caching mechanism in `HttpWorkflowsCacheManager.cs` is modified to handle eviction of workflow definitions and triggers separately boosting its efficiency.

* Add summary to IndexedWorkflowTriggers

A summary has been added to the 'IndexedWorkflowTriggers' class, providing a brief description. This description outlines that it represents a collection of indexed workflow triggers, promoting clearer understanding for future reference.

* Refactor memory caching feature into separate module

This commit separates the memory caching feature from the Elsa.Common module into a distinct Elsa.Caching module. This includes moving and renaming related files, such as the MemoryCacheFeature class and associated dependencies. The references in other modules and in the main solution file have been updated accordingly to include the new Elsa.Caching module.

* Add distributed caching and update async methods

Introduced a distributed caching feature with extensible change token signal publishing. Updated various cache-related methods to be asynchronous for improved performance and responsiveness. Also updated some workflow identity references for clarity.

* Add distributed caching with MassTransit support

This addition includes the implementation of a distributed caching system with MassTransit transport. The changes introduce necessary interfaces and services, new distributed caching feature along with the support for MassTransit as a transport option. Moreover, the instance management feature has been renamed to clustering feature for better clarity.

* Refactor queue naming and scope of MassTransitChangeTokenSignalPublisher

Queue name construction is adjusted in the RabbitMqServiceBusFeature and AzureServiceBusFeature modules for better organization and readability. MassTransitChangeTokenSignalPublisher is now a singleton service, ensuring the signal publisher can be shared across the application, increasing efficiency and performance. Also, introduced use of DistributedCacheFeature in MassTransitDistributedCacheFeature module for better modularization.

* Add caching capabilities to workflow definition service

This commit introduces caching to the workflow definition service, improving the performance for retrieving workflow definitions. 4 new classes have been created (`CachingWorkflowDefinitionService`, `EvictWorkflowDefinitionServiceCache`, `WorkflowDefinitionCacheManager`, and `IWorkflowDefinitionCacheManager`), and several existing classes have been updated to support caching. The caching also includes invalidation mechanisms, ensuring data consistency.

* Refactor caching mechanism in workflow definition

In the workflow definition module, the explicit caching functionality related to workflow definition versioning has been removed in favor of a more streamlined approach. Additionally, the manner in which services are registered has been altered. As a result, the caching now directly involves the overall workflow definition rather than individual versions, simplifying the caching logic and potentially improving the performance.

* Update MassTransitBroker and enable RealTimeWorkflows and SignalRHubs

The MassTransitBroker has been updated to Memory from RabbitMq. In addition, the RealTimeWorkflows and UseWorkflowsSignalRHubs features are now enabled in the code. This change will impact how the service communicates and processes real-time requests for workflow operations.

The reformatting involves a list of variable types in the HttpFeature module. Each type now appears on a new line for improved readability, making the code easier to maintain and review.

* Update HTTP workflows cache invalidation handler XML comment

* Remove unnecessary using directives

Unnecessary using directives were deleted across several files in the Elsa.Http module. This simplifies the code and will possibly improve execution speed. Specific deletions include those for Encoding, Unicode, Extensions, Collections.Generic, Linq, Text, and Tasks namespaces.

* Refactor HttpWorkflowsMiddleware constructor

This commit simplifies the HttpWorkflowsMiddleware class constructor. It removes the intermediary variables `_next` and `_options` and directly uses the passed arguments in the constructor. Now, the `next` and `options` parameters are used directly throughout the middleware.

* Simplify workflow retrieval in HttpWorkflowsMiddleware

This refactoring replaces the use of FindWorkflowDefinitionAsync and MaterializeWorkflowAsync with a single method, FindWorkflowAsync. This simplifies the middleware code and likely improves performance by reducing the number of database queries or service calls required to retrieve a workflow.

* Refactor workflow retrieval in HttpBookmarkProcessor

Simplified the workflow retrieval process in HttpBookmarkProcessor.cs. Replaced FindWorkflowDefinitionAsync and MaterializeWorkflowAsync methods with a single FindWorkflowAsync call. This reduces the complexity and improves efficiency in retrieving workflow.

Removed redundant lines of code to simplify workflow search functionality. This change simplified the FindWorkflowAsync method by directly calling the FindWorkflowAsync function in the workflowDefinitionService, thus increasing code readability and efficiency.

* Refactor Endpoint.cs for workflow retrieval

The method for obtaining a workflow in the Endpoint.cs script has been refactored and streamlined. The 'GetWorkflowDefinition' method is replaced by the 'GetWorkflowAsync' method which directly retrieves the workflow, without the intermediate step of materializing the workflow definition. This shortens the code and simplifies the process.

* Refactor InputFunctionsDefinitionProvider constructor

The constructor for InputFunctionsDefinitionProvider has been simplified by removing unnecessary private fields. Services are now directly used in the method instead of being stored in fields. This improves readability and reduces complexity in the class structure.

* Refactor WorkflowInstance with improved state handling

Simplified the methods for handling workflow and workflow state in the WorkflowInstance class. The refactoring also included some code clean-ups and variable renaming. The new implementation provides better readability and maintainability of the code by reducing unnecessary lines and improving structuring of objects and responses.

* Remove unused IBookmarkManager and update workflow functions

IBookmarkManager from ProtoActorWorkflowRuntime.cs file is removed due to its redundant status. Additionally, the "FindAsync" method has been updated to use a cancellation token. Also, annotations were added to the "ExportWorkflowStateAsync" and "ImportWorkflowStateAsync" methods to flag calls to functions that require unreferenced code.

* Remove unused ReSharper directive

Unused ReSharper directive in the file IndexTriggers.cs was identified and therefore removed. This change makes the code cleaner and easier to read.

* Update activity invocation in workflow runtime

Updated the DefaultBackgroundActivityInvoker service in the Elsa.Workflows.Runtime module to annotate the ExecuteAsync method with "RequiresUnreferencedCode" attribute. This change is made considering the potential code trimming issue. Additionally, simplified the process of fetching workflow by directly using FindWorkflowAsync method instead of FindWorkflowDefinitionAsync and MaterializeWorkflowAsync methods.

* Refactor code to simplify workflow definition loading

The code for finding and materializing workflow definitions has been simplified. Instead of loading the definition and materializing it into a workflow in separate steps, a new method called FindWorkflowAsync has been introduced to perform both actions at once. This reduces redundancy and makes the code more readable.

* Refactor WorkflowHostFactory to streamline workflow creation

This commit simplifies the workflow creation process in WorkflowHostFactory. It removes redundant code and extraneous methods, specifically the overloaded CreateAsync method which used WorkflowDefinition. Now, it directly finds and uses the Workflow instance, thereby simplifying the code base and improving maintainability.

* Refactor workflow retrieval in WorkflowInstance.cs

Changed the way workflow instances are retrieved from the WorkflowDefinitionService. Instead of obtaining the workflow definition and then materializing the workflow from it, the workflow is directly retrieved using the FindWorkflowAsync function. This simplifies the code and avoids unnecessary null-checks.

* Remove unnecessary whitespace in WorkflowInstance.cs

An extraneous whitespace character was identified and removed in the WorkflowInstance.cs file. This change contributes towards maintaining clean and readable code in the Elsa.ProtoActor module.

* Remove unnecessary comment in ProtoActorWorkflowRuntime

The unnecessary comment ("Load the workflow definition.") in the method TryStartWorkflowAsync of the ProtoActorWorkflowRuntime.cs file was removed. This is part of an ongoing effort to keep the codebase clean and readable.

* Update workflow management features and handlers

Added explicit notification handlers for DeleteWorkflowInstances and RefreshActivityRegistry in WorkflowManagementFeature.cs. Also, renamed RefreshActivityRegistryHandler.cs to RefreshActivityRegistry.cs for better clarity.

* Add multiple log record support to workflow execution log stores

The major change of this commit is the addition of methods to add multiple log records in the WorkflowExecutionLogStore, across different storage modules such as EntityFramework, MongoDB, Dapper, Elasticsearch and Memory. This ensures consistency and uniform behavior across different storage types. Furthermore, some reformatting and tidying up of the code were undertaken to maintain readability and clarity.

* Remove redundant workflow definition check

The workflow definition existence check and related service retrieval were removed from HttpWorkflowsMiddleware.cs. It was determined that this check was unnecessary as the workflow definition's existence is guaranteed at this point in the process, reducing redundancy in the code.

* Improve cancellation token usage in workflow execution

This commit refines the usage of cancellation tokens during the execution of workflows in Elsa.Server and HttpWorkflowsMiddleware. Previously, a cancellation token pair was created before ExecuteWithinTimeoutAsync was called, which limited duration control solely to that method. Now, cancellation tokens are included within ExecuteWithinTimeoutAsync method. This allows the method to observe any cancellation initiated by outer scopes, enhancing control over the timeout of operations.

* Add PersistStateAsync method to WorkflowHost

A new PersistStateAsync method has been added to the WorkflowHost, which enables the host to directly persist its own state. The method has been integrated into the DefaultWorkflowRuntime and HttpWorkflowsMiddleware. This update eliminates the need to continuously get instances of IWorkflowInstanceManager to save state, which improves efficiency and code readability.

* Refactor DefaultAlterationRunner service

This update simplifies the DefaultAlterationRunner service, reducing the number of code lines and removing unnecessary references. The workflow materialization step has been merged with the find workflow step, and unused namespaces have been dropped.

* Refine wording in IWorkflowHost interface documentation

The documentation for the 'CanStartWorkflowAsync' method in the IWorkflowHost interface has been cleaned up. The superfluous "or not" verbiage has been removed, making it easier to understand the method's function.

* Remove CancellationTokens struct and simplify cancellation handling

Removed the CancellationTokens struct and all its references across the code base. Simplified cancellation handling by using standard CancellationToken only. Also cleaned up redundant usages and unnecessary namespaces across various modules. This simplification better aligns with standard .NET conventions and reduces the code complexity.

* Implement ActivityHandle for better activity identification

The ActivityHandle class has been introduced to consolidate various activity identification parameters such as ActivityId, ActivityNodeId, ActivityInstanceId, and ActivityHash. This makes it easier to track and manage activities by reducing the number of parameters needed for identification. Adoption of ActivityHandle has been implemented across the codebase.

* Remove AzureContainerApps related code

This commit includes the removal of all the AzureContainerApps associated code from the ProtoActor Cluster. The deletion includes multiple files which had housed the AzureContainerApps cluster provider and all its supporting services, util functions, options, contracts, and models. This move might be towards refactoring the structure or removal of unwanted dependencies.

* Add distributed execution runtime and client

Removed some unused classes and created a distributed execution runtime using distributed locking and persistence. Introduced an interface for workflow clients and implemented two versions, a local one and one using `Proto.Actor`. Made some changes in other modules to add the necessary interfaces and methods. Also, added `DistributedLockingRuntime` module to implement distributed execution.

* Remove WorkflowClient.cs from Elsa.Workflows.Runtime

The WorkflowClient.cs file was removed from the Elsa.Workflows.Runtime project. It held placeholder methods that had not yet been implemented, making it unnecessary in the current codebase.

This update adds the ProtoActor implementation for data mappers and updates the DI configuration accordingly. It also updates the client interfaces for a more streamlined usage, and refactors the WorkflowHost to adapt to these changes. All changes were implemented in accordance with the new bookmark information model.

* Add functionality to create a new workflow instance

This commit introduces the capability to create a new workflow instance in the Elsa Workflow Runtime by enhancing existing workflow classes and creating the WorkflowClientFactoryExtensions class, in addition to adding the "IsNewInstance" parameter to multiple workflows and requests. It provides more flexibility in managing workflow instances and aids in building workflow processes that require instantiation of a new workflow.

* Remove Elsa.Runtimes.DistributedLockingRuntime module

This commit deletes the Elsa.Runtimes.DistributedLockingRuntime module from the project. Changes include removed code files related to features, services and commands under this module. The Elsa.sln file has been updated to reflect these changes, excluding the removed module from the solution.

* Add dynamic client type to WorkflowClientFactory

The WorkflowClientFactory now accepts a client Type parameter for dynamic client creation. This enables the factory to create different subclasses of IWorkflowClient based on the provided Type. The CreateClient function is updated in the WorkflowClientFactoryExtensions and IWorkflowClientFactory interface, and applied in HttpWorkflowsMiddleware.

* Implement Proto.Actor support in Elsa

A comprehensive change that introduces support for Proto.Actor clustering to Elsa.

With this removal, the project has become leaner and easier to maintain. It also eliminates potential confusion for future developers working on this project.

* Add WorkflowMatcher and replace BookmarkHasher with StimulusHasher

This commit introduces a new class, WorkflowMatcher, which represents a contract for finding triggers and bookmarks associated with workflow activities. It also renames and replaces all instances of BookmarkHasher with StimulusHasher to reflect a more accurate function relating to stimulus rather than bookmarks. Other necessary changes were made to ensure consistency with these updates across different classes. It's important to note that WorkflowInbox interface is now marked as obsolete.

* Incremental work on stimuli refactoring

* Refactor codebase to support new IWorkflowInvoker and invoke workflow logic

Multiple files updated to introduce a `IWorkflowInvoker` interface, implementation and supporting classes. This simplified how workflows are instantiated and invoked. Consequently, necessary adjustments made across multiple entities and endpoints to account for the updated invocation procedure. Old logic related to counting running workflows removed. Introduced stimulus concept while deprecating non-compliant classes and methods.

* bumped versions to fix dependency vulnerabilities (#5256)

* Update patch version in GitHub workflows

The version number used in the branch checking step of the GitHub workflows has been updated. Instead of scanning for the branch containing the patch version 3.1.2, it now scans for the branch that contains version 3.1.3. This change is aligned with the updated product version.

* Update git branch grep pattern in workflow file

The git grep pattern has been corrected to properly identify tagged versions in the GitHub Actions workflow. The correction ensures that the workflow script fetches the right branches as per the release tag instead of patch.

* Update grep command in packages workflow

The grep command used in the 'packages.yml' GitHub workflow was previously looking for the exact 'refs/tags/3.1.3' string. This commit simplifies the command by making it only look for '3.1.3'. This adjustment will streamline the process and potentially prevent issues with branch recognition.

* Update package versions and refactor code for Elasticsearch and JavaScript modules

Updated versions of numerous packages in the Directory.Packages.props file to their latest stable releases. This includes updates to Elasticsearch, JavaScript, and MongoDB packages among others.

The WorkflowInstanceStore also saw a minor adjustment.

* Refactor workflow management with workflow definition handles

The existing workflow management has been significantly refactored, introducing the concept of "Workflow Definition Handles". These handles allow for consistent management whether we're dealing with a specific workflow definition, a version of a definition, or more flexible version constraints. This refactor also adjusts how workflow instances are created, now using a more intuitive and detailed "WorkflowInstanceOptions" approach.

* Add ResumeBookmarkResult and update related methods

Implemented a ResumeBookmarkResult class to handle bookmark resumption results. Methods related to resuming bookmarks have been refactored to return this new class, providing more information such as bookmarks' matched state. Also, some methods were optimized to break the loop early if no bookmarks were found, improving code efficiency.

* Update workflow definition, execution and correlation

This commit focuses on enhancements and adjustments to workflow definition and execution. Notable changes include the addition of ExecuteResponse model and new test workflow scenarios. Refactoring has been performed to improve readability and efficiency in various components. It also includes an important fix for the correct application of WorkflowDefinition filters, primarily using both DefinitionId and DefinitionVersionId for more accurate results.

* Refactor runtime codebase for better structure and workflow control

This commit involves changes to functionally reorganize the runtime codebase for improved structure. It also allows for better handling of workflows, particularly through the addition of original bookmarks in the workflow execution context.

Optimized the constructor of 'WorkflowInvoker' by using 'IServiceScopeFactory' to get instances of required services. Removed the 'OriginalBookmarks' property from 'WorkflowStateExtractor' and 'WorkflowState', a subsequent change included in 'WorkflowGraphBuilder' as well. Reorganized the namespaces in 'Elsa.Workflows.ComponentTests' project. Added 'UseCache' in WorkflowServer configurations.

* Removed RunWorkflowParams class

This update deletes the RunWorkflowParams class within the Runtime Requests of the Elsa.Workflows module. The class was no longer needed, hence the elimination and cleanup in the codebase.

* Update RunWorkflowParamsMapper to handle null or empty fields

This commit modifies the RunWorkflowParamsMapper in the Elsa.ProtoActor module. It primarily treats the BookmarkId and TriggerActivityId fields to return null if they are empty, boosting the application's robustness against potential null or empty field issues.

* Refactor workflow handling and improve null checks

In this update, the handling of workflows was refactored to improve efficiency. The 'RunAsync' method now correctly uses 'WorkflowGraph' as a parameter, instead of 'Workflow'. Additionally, null checks for 'bookmarkId' and 'activityHandle.ActivityInstanceId' have been improved to avoid null and empty strings. Finally, when '_workflowInstanceId' is null in the 'WorkflowGrain' class, it is now properly initialized by parsing the cluster identity.

* Enable ProtoActor in Elsa.Server.Web

This commit turns on the use of ProtoActor within the Elsa.Server.Web bundle. This switch may affect the system's behavior and performance.

* Added new workflow scheduling and management features

Implemented new features for creating, running, and scheduling workflow instances. The implementation added new files for handling workflow runtime and scheduling features, including creating and running a workflow instance request, a mapper for the request, and handler services. Modified files include updating method calls according to the new requests, updating workflow definitions, and adjustment to method arguments in Hangfire job class.

* Handle null or empty workflow instance IDs and correlation IDs

This commit introduces null checks for workflow instance IDs and correlation IDs in the workflow infrastructure. Previously, the code assumed that the IDs were provided. It now gracefully handles cases where they might be null or empty, preventing possible null reference exceptions and ensuring more robust workflow execution.

Removed unnecessary using statement for Elsa.Workflows.Runtime.Requests in ResumeWorkflowJob.cs. Updated references from DispatchWorkflowInstanceRequest to ScheduleExistingWorkflowInstanceRequest for retrieving ActivityHandle and WorkflowInstanceId.

* Refactor AzureServiceBus module and integrate into web project

In this commit, changes were made to the AzureServiceBus module to use Topic definitions for subscriptions. The Subscriptions property in the AzureServiceBusOptions and the Topic property in the SubscriptionDefinition class are marked as obsolete and suggestions to use TopicDefinition.Subscriptions instead have been added. The AzureServiceBus module was also integrated into the web project and configured to use options from the appsettings.json.

* Refactor code to use async scopes and improve service dependencies

Refactored code to use async scopes for improved task management. Also organized service dependencies better by moving service fetching inside methods where they are needed and propagating necessary dependencies through method parameters for cleaner code.

* Add Azure Service Bus workflow component tests

This commit introduces a set of workflow component tests for Azure Service Bus integration. These tests encompass scenarios like message receiving, sending messages with correlation IDS, and sending single messages. In addition, 'SignalResetEvent' test helper was removed, a new test helper 'TriggerSignal' was added, and a Mock ServiceBusClient and ServiceBusAdministrationClient were added to the WorkflowServer fixture. Lastly, the NSubstitute package was added to the test project's dependencies.

* Add support for deferred tasks in workflow execution context

Added support for deferred tasks in the workflow execution context. This implementation allows tasks to be deferred and executed right after persistence of bookmarks in the workflow. A new middleware, ExecuteDeferredActivityTasks, is introduced to handle the execution of these deferred tasks.

* Refactor TriggerSignal and SendMessage activity execution

Refactored the execution of TriggerSignal and SendMessage activities by using context.DeferTask to ensure the activities run asynchronously. Also, made code format modifications and simplifications such as handling ApplicationProperties better in the SendMessage activity, and other minor changes.

* Update workflow ID generation method

The workflow ID generation method has been updated in the WorkflowBuilder. Previously, it was always generated by _identityGenerator. Now, it only gets generated if the definitionId or Id is null or empty, otherwise it uses the existing value. This change brings the ID generation practice in line with how we handle definitionId.

* Add support for service bus testing in workflow tests

Two new helper classes, DictionaryExtensions and MockServiceBusProcessor, have been added to support mocking Azure service bus in workflow component tests. Also, the tests have been updated to use SignalManager to ensure proper order of execution.

Converted ReceivedServiceBusMessageModel from a record to a class and updated relevant initialization code. Change was implemented because of the polymorphic serialization incabability of dealing with $type properties with records.

* Refactor WorkflowInstanceImpl for improved workflow management

This change refactors the WorkflowInstanceImpl class to improve workflow management. It implements queuing of RunWorkflowOptions while a workflow is running and ensures state before any workflow operations. Furthermore, workflow host creation is replaced with directly creating and managing workflow instances.

* Add DefaultFormattersFeature and update dependencies

A new feature, DefaultFormattersFeature, has been added to the Elsa.Common module. The WorkflowsFeature in the Elsa.Workflows.Core module has been updated to depend on this new feature. This will ensure that default JSON formatters are available across the application.

* Refactor JsonFormatter with JsonSerializerOptions property

Improved the JsonFormatter class by introducing a private JsonSerializerOptions property. The new implementation uses this property in the FromStringAsync method instead of initializing a new JsonSerializerOptions each time, improving efficiency. The JsonStringEnumConverter has also been moved to the class constructor.

* Refactor WorkflowInstanceImpl for improved code clarity

The refactor includes replacing direct field access with properties in multiple places for WorkflowGraph and WorkflowState. It also makes _queuedRunWorkflowOptions field readonly and removes unnecessary newline characters. These changes aim to improve readability, maintainability and encapsulation.

Additionally, it includes enhancements to the workflow execution, such as distributed locking and expanded logging capabilities for better debugging and tracking. Lastly, it introduces new configurations in application settings to fine-tune the workflow runtime environment.

* Refactor worker management in AzureServiceBus module

The codebase has been simplified by removing the unnecessary management of worker ref counts in the AzureServiceBus module. Previously, to manage worker instances, we kept a count of references to each worker and removed it when the count dropped to zero. This complexity has been entirely removed to make the module simpler and easier to maintain. Now we just create a worker when necessary, without tracking its usage across the codebase.

* Refactor workflow runtime with distributed locking and state checking

The workflow runtime has been refactored for better concurrency control and state management. The changes primarily include the introduction of distributed locking in action methods of the DistributedWorkflowClient and the handling of workflow instance states in the LocalWorkflowClient.

The DispatchAndWaitWorkflow test case in the BulkDispatchWorkflowsTests has been updated to use the new workflow client creation and instance running methods. Necessary namespace imports have also been added in the process to support the changes.

* Remove snapshot and persistence functionality from WorkflowInstanceImpl

This commit eliminates snapshot creation and persistence from the WorkflowInstanceImpl class. Methods related to these processes have been removed, including SaveSnapshotAsync(), ApplySnapshot(), and GetState(). This has also impacted the constructor and OnStarted() method where certain calls were made related to persistence. The need to manage and recover state asynchronously was eliminated, simplifying the implementation.

* Refactor workflow client implementations and update WorkflowStateMapper

Workflow clients in the modules Elsa.Workflows.Runtime and Elsa.ProtoActor have been refactored for better maintainability and readability. The WorkflowStateMapper in the Elsa.Workflows.Management is updated to include an "Apply" method, splitting the mapping functionality into smaller, more manageable methods. Also, usage of the Azure Service Bus Module in Elsa.Server.Web has been turned off.

* Update workflow definition in BulkDispatchWorkflowsTests

Changed the referenced workflow definition in the test scenario from EmployeeGreetingWorkflow to GreetEmployeesWorkflow. This update reflects more precise naming in our component tests for the BulkDispatchWorkflows scenario.

* Refactor BulkDispatchWorkflows and simplify error handling

The BulkDispatchWorkflows class in Elsa Workflows Runtime module has been refactored to simplify it. The detailed error handling with a list of errors has been removed and it is now directly dispatching child workflows without checking for a successful dispatch. The ProcessItem method has been removed which handled the errors previously, and the DispatchChildWorkflowAsync method no longer returns a dispatch response. This substantially simplifies the code and reduces its complexity.

* Update workflow runtime and distributed locking configuration settings

In the web server settings, the workflow runtime was changed from 'Distributed' to 'ProtoActor'. Also, the distributed lock provider setting has been moved into a new 'DistributedLocking' section in the configuration settings, allowing more detailed lock options to be set, including a lock acquisition timeout.

* Replace ProtoActor with DistributedRuntime in WorkflowServer

The current commit modifies our WorkflowServer configuration under our component tests. The "UseProtoActor" method which was previously used for runtime configuration has been commented out and replaced with "UseDistributedRuntime". This change suggests a shift towards a distributed runtime environment.

* Add new services and classes for workflow messaging

This commit adds new classes and services to facilitate workflow messaging. These include 'BroadcastWorkflowInboxMessageOptions', 'IWorkflowInbox', 'NewWorkflowInboxMessage', 'SubmitWorkflowInboxMessageResult', 'WorkflowInboxMessage', 'WorkflowInboxMessageDeliveryParams', and 'WorkflowInboxMessageFilter'. Additionally, changes were made in 'HttpWorkflowsMiddleware.cs' and 'WorkflowRuntimeFeature.cs' to use 'IWorkflowRunner' for executing workflows, and deprecated 'IWorkflowHostFactory' and 'WorkflowInvoker'. The messaging-related classes provide methods and properties to manage and manipulate workflow messages, delivery options and results. 'IWorkflowInbox' provides an interface for delivering messages to workflow instances while 'IWorkflowRunner' fulfills running workflows.

* Refactor WorkflowCancellationService for cleaner syntax

Aesthetic adjustments were made to the WorkflowCancellationService code to improve readability and maintainability. This includes tidying up line breaks, reformatting lists, correcting spelling in comments, and consolidating parameters in a function call.

The 'Elsa.Workflows.Runtime.Contracts' namespace was removed from the MassTransitWorkflowCancellationDispatcher file because it was not being utilized. This ensures a clean and efficient codebase by removing unnecessary imports.

* Remove Class1 from Elsa.Testing.Shared.Component

This commit deletes Class1.cs as it was no longer serving any purpose in the Elsa.Testing.Shared.Component. This removal helps keep the codebase clean and maintainable.

* Reduce default timeout in ISignalManager interface

The default millisecond timeout for the WaitAsync functions in the ISignalManager interface has been reduced from 5000ms to 1000ms. This change will speed up signal wait times in our testing framework.

* Refactor syntax representation in SendMessage activity

Simplified the syntax representation in the SendMesssage activity in the Elsa Azure Service Bus module. The SupportedSyntaxes property now utilizes a more concise array initialization.

* Removed obsolete 'Stimulus' property and adjusted consumers

The 'Stimulus' property in DispatchResumeWorkflows and DispatchTriggerWorkflowsRequest classes has been removed as it was marked obsolete. The DispatchWorkflowRequestConsumer has been adjusted to only use the 'BookmarkPayload' property. This ensures a cleaner code base and removes potential confusion between the properties.

* Rename GetNamedWorkflowGrain to GetNamedWorkflowInstanceClient

The method name GetNamedWorkflowGrain in both ProtoActorWorkflowClient and ClusterExtensions has been renamed to GetNamedWorkflowInstanceClient to improve code clarity. This change provides better semantics of what the function is purposed for.

* Remove unused snapshot classes

The commit removes the WorkflowGrainSnapshot and WorkflowInstanceGrainSnapshot classes from the Elsa.ProtoActor module. These classes were part of an older architecture and are no longer required.

* Remove unused field from Azure ServiceBus Worker

The _refCount field in the Worker class from the Azure ServiceBus module was unused. To maintain a clean codebase and improve readability, this field has been removed.

* Remove WorkflowInboxMessageRecord from Elsa.Dapper module

The commit includes the deletion of the entire WorkflowInboxMessageRecord class from Elsa.Dapper module. This file was managing various activities related to the workflow inbox messages, such as delivering messages to a workflow instance.

* Add new V3_2 migrations for all database providers

This commit introduces new V3_2 migrations for MySQL, SQLite, PostgreSQL, and SQLServer database providers. Included are `Up` and `Down` migrations, the corresponding Designer files, and specific Alterations and Runtime changes. SqlDbType specifications were also added for each.

* Refactor WorkflowDefinitionFilter and update related modules

Empty lines were removed between property declarations to improve readability in WorkflowDefinitionFilter. An error where 'filter.IsReadonly' was used instead of 'IsReadonly' was also corrected to ensure proper functionality. Additionally, WorkflowDefinitionFilter was imported in the Delete and Revert endpoint modules of the Elsa.Workflow.Api class to maintain consistency across the codebase.

* Change MongoUserStore to non-abstract class

The MongoUserStore class was previously tagged as an abstract class in the Identity module of Elsa.MongoDb. This update changes the MongoUserStore class from an abstract to a non-abstract (concrete) class to enable direct instantiation.

* Add ForwardedType attribute and update bookmarks

This commit introduces a new `ForwardedType` attribute to aid in forwarding types to new types when deserializing JSON. Additionally, the existing bookmarks related to workflow runtime activities have been updated. These changes also require modifying the `PolymorphicSerializer` in the Elsa.MongoDb project to handle types using the new `TypeHelper.GetLatestType` method.

* Fix logger reference in exception handling

The logger reference used in the catch block of the DefaultTriggerScheduler.cs file was incorrect. This commit corrects it by using the appropriate logger variable for logging any potential cron expression format errors.

* Refactor component tests and improve code cleanliness

This commit refactor the component tests, introduced new interfaces and events related to workflow definition and trigger change token signals. Removed an unused file, DictionaryExtensions.cs and refactored the GetOrAdd method to better handle null values. Some minor changes and improvements were also made in existing files to enhance overall code cleanliness.

Implement dispatch channels (#4949)
* Add DispatchWorkflowOptions and update MassTransit configuration

Introduced a new class `DispatchWorkflowOptions` to provide workflow dispatch options. Updated MassTransit configuration to include NET6.0 and NET7.0 support, and ensure correct MassTransit version usage per target framework version.

* Add support for configurable MassTransit message dispatching

Implemented a feature which allows for configurable MassTransit message dispatching. Added support for specifying channels and message brokers. Message dispatching code was massively refactored and relevant endpoints and response models were updated to support new message dispatching features.

* Add IEndpointChannelFormatter interface and implementation

An interface for formatting channel queue names, 'IEndpointChannelFormatter', has been added, along with its default implementation 'DefaultEndpointChannelFormatter'. The code that uses hardcoded queue name formatting has been modified to use the new formatter instead, making it more configurable and reusable. The implementation of the formatter uses the 'Humanizer' library to kebab-case the channel names.

* Add channel dispatch option to workflow activities

Introduced `WorkflowDispatcherChannelOptionsProvider` to provide dropdown channel options for workflow dispatch-related activities. Updated `DispatchWorkflow` and `BulkDispatchWorkflows` activities to include a new dropdown input for specifying a dispatch channel. Also, included the selected channel name in the `DispatchWorkflowOptions` during workflow dispatching process.

* Update MassTransit configurations and remove unused code

The MassTransit setup in Elsa.MassTransit module has been simplified by removing conditional code for different .NET versions. Additionally, unused parameter '__X_Channel' in 'DispatchWorkflowDefinition' was removed. Lastly, the MassTransit broker in Elsa.Server.Web was switched from RabbitMq to AzureServiceBus.

* Refactor dispatch workflow classes and methods

Simplified the class, method and variable names related to workflow dispatching in the Elsa.Workflows.Runtime module. For example, the 'WorkflowDispatcherChannelDescriptor' class was renamed to 'DispatcherChannel'. This refactoring was performed to make code more readable and maintainable by removing redundant wording in the naming convention.

* Update GitHub Workflow to support feature and issue branches

The workflow changes add support for feature and issue branches. Now, it extracts the branch name and verifies the commit exists in the given branch rather than just 'main'. The versioning scheme is also modified to include the branch name and not just the run number.

* Add 'bug/*' to triggering branches in packages workflow

The 'bug/*' pattern was missing from the triggers that initiate the GitHub actions within our packages workflow. This update includes any branch with a 'bug/' prefix to the list, allowing bug-related branches to start jobs in our CI/CD pipeline.

* Remove 'issue/*' and 'bug/*' branches from packages workflow

The 'issue/*' and 'bug/*' branches have been removed from the GitHub action workflow for packages. This change was made to simplify the workflow and optimize the triggering of package building.

* Update GitHub workflow to handle main branch versioning

This commit modifies the GitHub workflow script to accommodate changes when the branch name is "main." If the branch name is "main", a preview version is used. It also updates script execution to print the branch name for easier debugging and verifies commit existence on the correct branch instead of dispatch channels.

* Enclose branch names in quotes in packages.yml

The update modifies the branch names in the packages.yml GitHub Actions workflow file. The change consists of enclosing the branch names 'main' and 'feature/*' in single quotes, ensuring compatibility and preventing potential string interpretation issues.

* Update GitHub workflows package configuration

The workflows package configuration has been updated to specifically watch for changes on 'feature/dispatch-channels' rather than on all feature branches. This change will prevent unnecessary builds on less relevant feature branches.

* Update trigger branches in packages workflow

The triggering branches in the packages workflow have been updated. Previously, only changes in the 'main' and 'feature/dispatch-channels' would trigger the workflow, now any 'feature/*' branch will. This will cause more frequent and comprehensive testing.

* Add 'patch/*' to workflow trigger branches

This update adds 'patch/*' to the list of branches in .github/workflows/packages.yml that can trigger the workflow. It will allow the workflow to be initiated not just for main and feature branches, but also for patches.

* Add 'preview/*' to workflow triggers

This commit adds a new trigger for the GitHub Actions workflow. It now also responds to push events on 'preview/*' branches, allowing for automated testing and building of these preview branches.

* Update branch name extraction in GitHub Actions

The extraction of the branch name has been slightly modified in the packages.yml GitHub workflow file. This alteration ensures the correct branch name is obtained for further processing within the workflow without any discrepancy.

* Update branch name extraction in packages.yml

Corrected the syntax for extracting the branch name within the packages.yml github workflow file. Added an extra line to print out the ref which might be useful for debugging.

* Update branch name extraction in GitHub workflow

The commit simplifies the way the branch name is being extracted from the GitHub ref in the packages.yml workflow file. The new method employs straightforward string manipulation, making it easier to understand and debug in case of potential issues.

* Add extraction of branch name in workflow

Added a new line in the GitHub workflow file (.github/workflows/packages.yml) to extract the last part after the final slash from the branch name. This enhancement allows cleaner naming conventions, especially in cases where branches are named feature/issue-123, as it will only retain 'issue-123'.

* Update package naming in Github workflow

The Github workflow has been updated to handle package naming more effectively. Previously, the branch name was used directly for package versioning. Now, the last part of the branch name is extracted and used as the package prefix. If the branch name is "main", the package prefix is set to "preview".

* Move and add environment variable assignments

The placement of the assignment for BRANCH_NAME environment variable was moved for better readability. Additionally, the PACKAGE_PREFIX environment variable was also added. These environment variables are crucial for subsequent steps in the GitHub workflow.

* Add workflow dispatch validation and response handling

Removed several specific dispatch response classes and consolidated all types of dispatch responses into a single DispatchWorkflowResponse class. Added a new ValidatingWorkflowDispatcher service to validate dispatch requests before they're sent. Updated several classes to work with these changes, including the BackgroundWorkflowDispatcher, MassTransitWorkflowDispatcher, and the API endpoint class.

* Handle dispatch workflow failures with exceptions

The DispatchWorkflow and BulkDispatchWorkflows activities now throw a FaultException when the dispatch operations fail. Previously, these operations were not checking for success and could fail silently. Now, an unsuccessful dispatch response results in a FaultException with an error message from the dispatch response.

Add a more generic UIHandler to customize how inputAttributes can be handle by UI (#4688)
* add a more generic UIHandler to customize how inputAttributes can be handle by the ui

* Add IPropertyUIHandlerResolver and update PropertyUIHandlerResolver

Introduced a new interface, IPropertyUIHandlerResolver, to resolve UI options for a property. Refactored PropertyUIHandlerResolver to implement this interface and removed the unnecessary partial class structure. Also, cleaned up some unnecessary usings in various files for better code organization.

* Refactor variable name and description in InputDescriptor

The 'uISpecifications' variable in the InputDescriptor model is renamed to 'uiSpecifications' for better readability. Additionally, the associated comment was revised to explain that the dictionary is used by the UI.

* "Refactor codebase for improved organization and cleaner architecture"

The codebase has been significantly refactored, moving several classes to more appropriate namespaces for improved organization and cleaner architecture. This includes shifting UI hint handlers, activities, and memory-related components, amongst others. The changes should improve code readability and maintainability, but as this is a broad refactoring effort, thorough regression testing is advised.

* Add CheckList UIHint with associated handler and provider

This update introduces a new UIHint called CheckList to the Elsa.Workflows.Core. This includes the necessary handler and provider classes. The handler is registered in the WorkflowsFeature.cs, and the CheckList UIHint key has been added to the InputUIHints.cs. Various associated files have been created in both the Elsa.Api.Client and Elsa.Workflows.Core project to support this new UIHint.
