Summary

Publish the evidence-only handoff for merged tenant rollover hardening PR #267, and replace stale current-state impressions with verified prov10 foundation observations.

The behavioral source is merged master 84099293570af5ab06f7d8e2f93e7e6ae2c0236f. Authoritative postmerge Build Test Image 41696483989, CodeQL 41696338523 and freshness 41696488100 pass. The default fixture proves literal YAML/password/worker transport followed by real PostgreSQL identity, snapshot/signal/fidelity/isolation, image smoke and HIGH/CRITICAL Trivy.

A subsequent read-only check verifies the approved prov10 service principal, exact tenant/subscription, zero Container Apps in both target resource groups, and both PostgreSQL17/B1ms servers Ready in Central US. No cloud resource is changed.

The recorded immutable tooling test image is not an admitted0.55.67 release or an authorized alternative. Requested0.55.67 admission, source writer freeze/final carry, actual target acceptance and cutover remain pending. Customer production is untouched.

Linked Defect / Plan Reference

• DELIVERY_PLAN.md defect ID: N/A; evidence handoff for authorized quarterly migration and merged fix(ops): prepare safe registry-driven tenant rollover #267.
• Audit doc reference: Migration execution handoff, current handoff and execution RCA.
• ADR (if applicable): N/A; no runtime or architectural change.

TDD Process

• RED test written first; observed it fail for the expected reason - N/A for this documentation-only PR; actual behavioral RED/GREEN belongs to merged fix(ops): prepare safe registry-driven tenant rollover #267.
• GREEN: minimal implementation that turns the test green - N/A; no implementation change.
• Refactor (if any) keeps the test green - N/A; no refactor.
• Permanent regression guard added (where applicable - see existing patterns in api/src/security/) - N/A; existing default fixture and offline guards are already merged.

Feature / Bug-Fix Commit Checklist (standing rule)

Every behavioral change must include all that apply. Tick or strike through with N/A + reason.

• Unit Tests - service-level and controller-level coverage of the new behavior - N/A; no new runtime behavior.
• E2E Tests - end-to-end spec under api/test/e2e/ exercising the feature through HTTP - N/A; no HTTP/UI change.
• Live Integration Tests - new section in scripts/live-test.ps1 runnable against local + Docker + Azure - N/A; no new integration behavior. Actual target acceptance remains a deployment gate, not claimed here.
• Feature Documentation - dedicated doc in docs/ with architecture, RFC references, Mermaid diagrams, test coverage - existing execution document updated; no new diagrams or code blocks requiring rendering changes.
• INDEX.md Update - add the new doc reference to docs/INDEX.md - N/A; existing indexed document.
• CHANGELOG.md Update - [Unreleased] entry with full test counts and feature summary - scoped evidence entry; no fabricated new behavioral test counts.
• Session & Context Updates - Session_starter.md and docs/CONTEXT_INSTRUCTIONS.md - authoritative current state supersedes historical pending notes.
• Version Management - bump api/package.json (and any other version refs) when behavior changed - N/A; documentation only, product version and all manifests/lockfiles unchanged.
• Response Contract Tests - API responses contain ONLY documented fields (key allowlist assertion at unit + E2E + live) - N/A; no response change.

Standing Rules Acknowledgment

• No em-dash (Unicode U+2014) anywhere in the diff. Verified via Select-String -Pattern ([char]0x2014).
• No git commit --amend on history that has been pushed.
• No new credentials, tokens, or secrets committed to source. Forbidden patterns regression spec at api/src/security/forbidden-source-patterns.spec.ts will catch known anti-patterns.
• Migrations are additive-only (expand-contract for column changes). Migration linter at api/src/scripts/lint-migrations.ts enforces this. N/A; no migration change.

Destructive Migration Override (skip if not applicable)

• This PR contains a NEW destructive Prisma migration (DROP TABLE/COLUMN, ALTER COLUMN ... TYPE, RENAME, INSERT ... SELECT FROM)
• I have set ALLOW_DESTRUCTIVE_MIGRATION=1 in the CI environment for this PR
• Justification (required if box above is ticked):

  <!-- Why this destructive change is necessary, what the rollback path is, and which release window it ships in -->
  

N/A: this PR is documentation only and authorizes no restore.

Reviewer Hint

Diff areas worth special attention from the reviewer:

• Distinguish historical preparation statements from authoritative current-state handoffs.
• Keep tooling/source evidence separate from release admission, provider guarantees and actual target acceptance.
• Verify the digest claim is limited to authorized CI push/smoke-pull evidence; direct package REST inventory, permanent retention and off-device backup recovery are not claimed.
• Self-improvement applied: explicit superseding state and scoped evidence claims prevent fixture success from appearing to authorize a destructive operation.
• Design disposition accepted: evidence-only update; no new responsibilities, coupling, dependency or abstraction.

What changed in this PR

This documentation-only PR records the postmerge evidence for tenant rollover hardening in #267 and updates SCIMServer’s handoff documents with verified prov10 foundation observations. It changes no runtime behavior or cloud resources.

Changes:

• Records merged-source validation, review results and the tooling test image digest.
• Documents both target PostgreSQL servers as Ready and zero target Container Apps, explicitly superseding historical pending notes.
• Keeps release 0.55.67 admission, final frozen data carry, target acceptance and cutover pending, with recovery limitations documented.

Postmerge documentation acceptance: mastera80fafb219c07628c7cd0b4fb67bed983570e7cf passes authoritative freshness41701994315 and automatic CodeQL41701918252. The documentation worktree tree matches merged master and is clean. This merge changes documentation only; the already validated behavioral artifact/source84099293570a and its full postmerge matrix41696483989 remain the runtime evidence. No redundant runtime rebuild, performance campaign, deployment, restore, source-writer change or tenant cutover was performed. Fresh verified-identity prov10 provider reads confirm both PostgreSQL17/B1ms servers Ready and zero target Container Apps. Requested0.55.67 still lacks admission; this evidence update does not substitute another release or waive any operational gate.
