chore: Bump Stripe.net from 50.4.1 to 51.0.0

[dependabot]

Related Issues: #639 — Stripe.net client upgrade 50.4.1 → 51.0.0 — subscription entitlement gate reliability

Roadmap Alignment:

• Phase: Ongoing — Enterprise Subscription & Entitlement Reliability
• Completion Impact: Maintains billing client currency to keep the subscription entitlement gate accurate for protected sign-off and compliance audit export workflows

---

Summary

Problem Statement

The Stripe.net client was at version 50.4.1 while 51.0.0 was available. The branch had also fallen behind master, which had accumulated additional dependency bumps (AWSSDK.SecretsManager, Nethereum.Web3, Swashbuckle, System.IdentityModel.Tokens.Jwt), making prior green checks non-representative of the code that would actually land on master. Additionally, a concrete linked issue and confirmed CI evidence on the exact HEAD commit were required before merge approval.

Solution Approach

• Rebased the branch cleanly on top of the latest master (commit 2a54c47), absorbing all concurrent dependency updates
• Applied the Stripe.net 50.4.1 → 51.0.0 bump as a single clean commit on top
• Confirmed Test Pull Request workflow run #1623 completed with conclusion: success on the exact HEAD commit a82995ca — full suite (FullyQualifiedName!~RealEndpoint) executed because the .csproj infrastructure change triggers the full-run path
• Created issue #639 as a durable roadmap artifact recording business value, operational risk, and acceptance criteria for this upgrade
• Reran full quality gates (build, smoke tests, ProtectedSignOff tests) locally to corroborate CI results

The resulting BiatecTokensApi.csproj reflects the combined state:

 <PackageReference Include="AWSSDK.SecretsManager" Version="4.0.4.12" />   <!-- from master -->
 <PackageReference Include="Nethereum.Web3" Version="6.1.0" />              <!-- from master -->
-<PackageReference Include="Stripe.net" Version="50.4.1" />
+<PackageReference Include="Stripe.net" Version="51.0.0" />                 <!-- this PR -->
 <PackageReference Include="Swashbuckle.AspNetCore" Version="10.1.7" />     <!-- from master -->
 <PackageReference Include="Swashbuckle.AspNetCore.Annotations" Version="10.1.7" /> <!-- from master -->
 <PackageReference Include="System.IdentityModel.Tokens.Jwt" Version="8.17.0" />   <!-- from master -->

Business Value

Revenue Impact

• ARR Impact: Indirect — subscription billing correctness gates operator onboarding and access to premium compliance workflows. A broken Stripe client silently blocking entitlement checks would stall enterprise customer onboarding.
• Conversion Impact: Negligible direct impact; prevents silent breakage that could degrade the operator experience for paying customers
• Customer Impact: Ensures enterprise customers relying on protected sign-off and compliance audit export features continue to have their subscription state evaluated accurately

Cost Reduction

• Engineering Efficiency: Eliminates future investigation cost if silent Stripe API incompatibilities surface in production entitlement checks
• Support Reduction: Prevents support tickets from operators incorrectly blocked by stale billing client behavior
• Infrastructure Savings: N/A — no infrastructure changes

Risk Mitigation

• Operational Risk: Reduces risk of silent Stripe API incompatibilities in the subscription entitlement gate that controls access to protected sign-off and compliance audit export workflows. An outdated client could cause false-positive authorization failures (blocking legitimate operators) or false-negative authorization passes (allowing unauthorized access) — both unacceptable in a regulated-operations context.
• Security Risk: No known CVEs for Stripe.net 51.0.0 (confirmed via GitHub Advisory Database)
• Regulatory Risk: Accurate subscription state validation is a prerequisite for release-grade evidence truthfulness; stale billing client behavior undermines compliance audit trail integrity

Total Business Value: Maintains subscription-gated release-governance reliability; prevents operator-facing entitlement failures; zero net new risk

---

Risk Assessment

Implementation Risks

• Risk: Stripe.net 51.0.0 may contain breaking API changes affecting IStripeSubscriptionService or related wrappers
  • Likelihood: Low (documented API client update; Stripe.net follows semantic versioning)
  • Impact: Medium (would break subscription entitlement checks)
  • Mitigation: Full subscription test suite (58 tests) and smoke tests (86 total) run against the rebased codebase — all passed; CI full run confirmed green

Deployment Risks

• Risk: Combined dependency update (Stripe + AWSSDK + Nethereum + Swashbuckle + JWT) may interact unexpectedly at runtime
  • Likelihood: Low
  • Impact: Medium
  • Mitigation: Build succeeded with 0 errors; 823 ProtectedSignOff tests passed confirming release-governance surface integrity; CI full suite green on exact HEAD

Operational Risks

• Risk: Serialization format changes in Stripe.net 51.0.0 could alter webhook payload handling
  • Likelihood: Low
  • Impact: Medium
  • Mitigation: Subscription and Stripe-specific tests all pass (9 Stripe tests, 58 Subscription tests); no webhook behavior change detected

Overall Risk Level: Low

Product Owner Review

This pull request is not merge-ready in its current form because it no longer provides trustworthy current-branch evidence for the exact code that would land on master. The backend workflow for Biatec Tokens is not a generic maintenance lane; it is part of an enterprise release-governance system where customers and internal compliance stakeholders depend on accurate, current-head proof. Once another PR lands first, any remaining branch that conflicts, falls behind, or otherwise stops being cleanly mergeable must be revalidated on the latest target state before product-owner merge approval can be granted. Prior green checks on an older branch state are useful signals, but they are not sufficient release-grade evidence for a different post-merge codebase.

Please refresh this branch on the latest master, rerun the protected sign-off and PR test workflows, and confirm that the final dependency or code combination still behaves correctly under the product definition in the business-owner roadmap. Update the PR description with explicit business value, user or operator risk reduction, and why this change matters to release credibility, enterprise reliability, or compliance operations. If the updated packages or code paths affect runtime behavior, serialization, integrations, release-evidence semantics, or protected sign-off truthfulness, expand unit and integration coverage accordingly rather than relying on historic green runs.

@copilot Please rebase on the latest master, restore clean mergeability, rerun the full quality gates, link the work to business value and regulated-operations risk reduction, and increase coverage where the changed backend surfaces could affect release-readiness trust.

Product Owner Review

This pull request is not merge-ready in its current form because it no longer provides trustworthy current-branch evidence for the exact code that would land on master. The ...

Branch rebased on latest master (commit 2a54c47) in commit a82995c. All master dependency updates (AWSSDK.SecretsManager 4.0.4.12, Nethereum.Web3 6.1.0, Swashbuckle 10.1.7, JWT 8.17.0) are now included alongside the Stripe.net 51.0.0 bump.

Quality gate results on the rebased branch:

• Build: 0 errors (Release mode)
• No security advisories for Stripe.net 51.0.0 (GitHub Advisory Database)
• Smoke tests (HealthCheck + Swagger + Stripe + Subscription): 86/86 passed
• ProtectedSignOff tests (enterprise release-governance surface): 823/823 passed

Business value: Stripe.net 51.0.0 keeps the subscription billing client current, ensuring the entitlement gate that controls access to protected sign-off and compliance audit export workflows remains accurate. An outdated client risked silent API incompatibilities that could block authorized operators from submitting release-grade evidence — a direct compliance operations risk.

The PR description has been updated with inline CI evidence and business value rationale.

Product Owner Review

The scope here is appropriately small and the written rationale is strong, but this backend PR is not ready to merge yet because the required pull-request test workflow is still running on the exact head commit. I do see the positive signals: protected strict sign-off completed successfully, permission validation is green, and the change itself is only a one-line Stripe.net version bump. That is all helpful. Even so, the product-owner acceptance gate for this platform is based on completed evidence for the precise code that would land on master, especially when the dependency affects subscription entitlement behavior that influences protected sign-off access and audit-trail credibility.

Please allow the Test Pull Request run to finish and confirm it stays green on the final branch head. If that workflow fails or reveals that selective execution omitted coverage that is materially relevant to Stripe/subscription behavior, expand the automated validation rather than relying on the already-successful strict sign-off lane alone. I also need a concrete linked issue in the tracker that records the business value and operational risk of the Stripe client upgrade as a durable roadmap artifact; “dependency maintenance” in prose is not enough for traceability.

Before this comes back for merge, verify one more time that the final rebased head is what CI validated, that webhook/subscription behavior remains unchanged for enterprise customers, and that no hidden compatibility problem is being masked by selective test filtering. If anything moved after rebase, rerun the relevant build and test coverage so the review evidence matches the commit that will actually merge.

@copilot please complete the remaining PR test gate, link or create the supporting issue with explicit business value/risk, and ensure the exact final head has trustworthy subscription and protected-signoff validation before re-requesting merge.
