+## Deep-Research Roadmap Alignment
+
+This section is a deep-research-derived calibration layer. It sharpens roadmap language against current repo truth without reopening already-promoted specs or overstating sellability from foundations alone.
+
+### Confirmed priorities
+
+- Deep-Research-derived: Customer Review Workspace remains the primary sellability gap, but the repo already contains the foundational and productization specs. The roadmap priority is calmer customer-safe review consumption, not a second portal or a parallel reporting stack.
+- Deep-Research-derived: Decision-centered operating remains the primary operator workflow gap. The repo already has governance inbox and convergence anchors, so the remaining roadmap work should narrow toward decision-register, ownership, closure, and approval semantics instead of launching more isolated admin surfaces.
+- Deep-Research-derived: PSA/ITSM remains an integration lane, not a product-redefinition. The correct posture is handoff, reference continuity, and auditability rather than a TenantPilot-native helpdesk.
+
+### Newly elevated gaps
+
+- Deep-Research-derived: Governance Artifact Lifecycle & Retention v1 should be elevated into the now lane. Current repo truth covers lifecycle taxonomy, review-pack retention, and artifact-truth semantics in pieces, but not a unified governance-artifact lifecycle contract.
+- Roadmap Recommendation: Enterprise Access Boundary & Support Access Governance v1 should exist as a narrow early access-governance slice built around support access request, reason, TTL, approval, banner, and exportable audit trail. Broad workspace SSO/OIDC/SCIM remains later.
+
+### Reordered priorities
+
+- Deep-Research-derived: Commercial lifecycle moves up. The commercial lane should be framed as SaaS trust, workspace read-only behavior, artifact access, and lifecycle semantics, not as a future billing engine.
+- Deep-Research-derived: Cross-tenant compare and promotion remains important, but the roadmap should talk about lineage, approval, evidence, rollback references, and decision linkage before it talks about settings push.
+- Deep-Research-derived: Auditor-ready delivery and broader governance packaging stay valuable, but they should follow calmer review consumption, decision routing, artifact lifecycle clarity, and commercial-state truth.
+
+### Deferred / not-now themes
+
+- Roadmap Recommendation: full operator-UI localization is not the v1 localization target; customer-facing glossary, review, pack, and notification surfaces come first.
+- Roadmap Recommendation: broad workspace SSO/OIDC, SCIM, group-to-capability mapping, and automated provisioning stay out of P0 unless support-access risk turns acute.
+- Roadmap Recommendation: advanced APIs/webhooks, visible AI runtime consumers, and AI-assisted drafting stay later scale layers.
+
+### Productization vs. Foundation distinction
+
+- Repo-verified foundations do not automatically mean sellable or customer-safe product slices.
+- Specs 248, 249, 250, 251, 252, 256, 258, 260, 262, 263, and current-branch 264 prove real foundations or prepared follow-through, but the roadmap should still distinguish `foundation-only` from `productization gap`.
+- Stored reports, localization, commercial lifecycle, governed AI, and governance packaging all already have some repo truth. The open work is mainly calmer consumption, lifecycle semantics, and repeatable product delivery.
+
+### Risks of admin-tool sprawl
+
+- Deep-Research-derived: TenantPilot loses focus when every new operator concern gets its own top-level page instead of feeding review, decision, evidence, and governance-package flows.
+- Deep-Research-derived: More admin surfaces do not close the core gap. Decision records, accepted-risk visibility, evidence lifecycle, customer-safe review consumption, and portfolio-safe workflow continuity do.
+- Roadmap Recommendation: prefer decision-first routing, diagnostics-second disclosure, and evidence-third drilldown over raw technical dashboards or isolated remediation consoles.
+
+## Deep-Research Anti-Patterns
+
+Do not prioritize these themes ahead of the aligned now and next lanes.
+
+- anti-pattern: generic M365 admin mirror
+- anti-pattern: generic helpdesk or PSA replacement
+- anti-pattern: device-action tooling without governance context
+- anti-pattern: generic automation builder
+- anti-pattern: raw technical dashboards as the primary product surface
+- anti-pattern: AI copilot islands without AI governance
+- anti-pattern: broad multi-cloud expansion before Microsoft governance is productized
+- anti-pattern: eDiscovery or broad GRC-suite clone
+- anti-pattern: a new top-level page for every technical state or exception

+## Deep-Research Alignment Reference (non-queue)
+
+This section is a deep-research-derived calibration layer. It is intentionally not the active queue. Use it to keep candidate naming, scope, and status language aligned with current repo truth.
+
+### Customer Review Workspace v1
+
+- **Status markers**: repo-verified, productization gap
+- **Roadmap lane**: Now
+- **Current repo truth**: Specs 249 and 258, plus the implementation ledger and current review surfaces, already prove the foundational and productization path for customer-safe review consumption.
+- **Problem**: Customer-safe review consumption remains the clearest sellability gap whenever review truth, accepted risks, evidence, and package delivery still require operator translation.
+- **Deep-Research-derived sharpening**: Keep the lane focused on one customer-safe read-only review surface, findings summary, accepted-risk visibility, evidence viewer, review-pack download, management summary, RBAC/capability enforcement, and audit trail.
+- **Non-goals**: no generic customer portal, no helpdesk surface, no raw diagnostics by default, no admin mirror.
+
+### Decision-Based Governance Inbox + Decision Register v1
+
+- **Status markers**: repo-verified, productization gap, roadmap recommendation
+- **Roadmap lane**: Now
+- **Current repo truth**: governance inbox, findings queues, operations attention, review follow-up, and Specs 250 and 257 already anchor the decision surface, but there is still no bounded decision-register follow-through.
+- **Problem**: Findings, alerts, runs, and reviews still need one calmer decision layer with ownership, due state, reason, impact, next action, linked evidence, linked `OperationRun`, accepted-risk path, closure reason, and escalation hooks.
+- **Deep-Research-derived sharpening**: treat the missing slice as decision-register and approval/closure follow-through over current inbox foundations, not as another queue page.
+- **Non-goals**: no generic Kanban board, no PSA clone, no XDR incident console.
+
+### Governance Artifact Lifecycle & Retention v1
+
+- **Status markers**: foundation-only, roadmap recommendation, spec candidate
+- **Roadmap lane**: Now
+- **Current repo truth**: Spec 262, the lifecycle-governance standard, review-pack retention, and artifact-truth semantics provide taxonomy-first foundations, but not a productized governance-artifact lifecycle.
+- **Problem**: Evidence snapshots, stored reports, review packs, and future decision records are governance artifacts and must not be treated like short-lived operational rows.
+- **Roadmap Recommendation**: v1 should cover artifact-type registry, immutable artifact reference, artifact state, retention state, export bundle, preserve or hold state, soft delete or hard delete semantics, suspended/read-only workspace behavior, and audit trail for export/delete/hold.
+- **Non-goals**: no legal case management, no full eDiscovery system, no Purview clone.
+
+### Commercial Entitlements & Billing-State Lifecycle v1
+
+- **Status markers**: repo-verified, foundation-only, productization gap
+- **Roadmap lane**: Now
+- **Current repo truth**: Specs 247 and 251 already ground workspace entitlements, lifecycle state handling, and read-only gating.
+- **Problem**: Workspace, plan, and billing state still need clearer artifact-access, archive, scheduled-deletion, and customer-trust semantics.
+- **Deep-Research-derived sharpening**: keep the lane framed as commercial lifecycle, workspace read-only behavior, artifact access by state, capability gating, and audited state change semantics rather than payment-engine work.
+- **Non-goals**: no payment gateway, no invoicing engine, no tax engine.
+
+### External Support Desk / PSA Handoff v1
+
+- **Status markers**: repo-verified, productization gap
+- **Roadmap lane**: Next
+- **Current repo truth**: Spec 256 and the current support-request handoff already prove a bounded create/link model.
+- **Problem**: MSP governance work still needs cleaner PSA/ITSM handoff with external reference continuity, evidence/context transfer, due date/status mapping, closure sync or manual reconciliation, audit trail, and webhook-ready shape.
+- **Deep-Research-derived sharpening**: keep PSA/ITSM as integration and handoff, not as a TenantPilot-native helpdesk.
+- **Non-goals**: no PSA clone, no project-management suite, no generic helpdesk.
+
+### Customer-Facing Localization v1
+
+- **Status markers**: foundation-only, productization gap
+- **Roadmap lane**: Next
+- **Current repo truth**: Spec 252 and the locale resolver already provide the foundation.
+- **Problem**: DE/EN customer-facing review consumption still lacks full glossary discipline, customer-safe labels, review-pack templates, notification text, and fallback confidence.
+- **Deep-Research-derived sharpening**: v1 means glossary, review-workspace strings, review-pack templates, evidence labels, status/reason/impact/next-action labels, locale-aware formatting, fallback behavior, and missing-key tests.
+- **Non-goals**: no full operator-UI localization in v1, no marketing translation project, no uncontrolled string extraction.
+
+### Cross-Tenant Compare & Promotion with Lineage v1
+
+- **Status markers**: repo-verified, productization gap
+- **Roadmap lane**: Next
+- **Current repo truth**: Spec 043 is already repo-real for compare and preflight, and Spec 264 now carries the execution follow-through on this branch.
+- **Problem**: portfolio action still needs governance-first execution with impact preview, promotion proposal, approval, `OperationRun` trace, before/after evidence, baseline lineage, rollback reference, and decision-record linkage.
+- **Deep-Research-derived sharpening**: keep this lane governance-first. It is not a generic policy-push or settings-sync surface.
+- **Non-goals**: no unmanaged mass remediation, no generic settings push, no admin mirror.
+
+### Governance Service Packaging v1
+
+- **Status markers**: repo-verified, productization gap
+- **Roadmap lane**: Next
+- **Current repo truth**: Spec 260 and current governance-package delivery cues already exist.
+- **Problem**: MSPs need repeatable governance-service packages with review cadence, included controls/reports, stakeholder mapping, schedule, package-specific review-pack semantics, and entitlement binding.
+- **Deep-Research-derived sharpening**: productize packaging as a repeatable governance service, not as one-off executive exports or bespoke customer projects.
+- **Non-goals**: no CRM, no PSA, no billing system.
+
+### Enterprise Access Boundary & Support Access Governance v1
+
+- **Status markers**: roadmap recommendation, spec candidate
+- **Roadmap lane**: Next when support-access gaps turn operationally acute; otherwise Later
+- **Current repo truth**: audit docs and handover material already show break-glass, system access, and platform support seams, but not a bounded support-access governance package.
+- **Problem**: support access, delegated access, and future impersonation need customer-safe auditability, reason capture, TTL, approval, operator-context banner, and exportable access logs before broader SSO/SCIM work.
+- **Roadmap Recommendation**: prioritize support-access request, reason required, time-limited access, capability-bound access, customer-visible audit trail, optional approval, break-glass separation, operator context banner, and exportable access log.
+- **Non-goals**: no full IAM suite, no immediate SCIM requirement unless separately promoted, no unrestricted impersonation.
+
+### Private AI Execution Governance Foundation v1
+
+- **Status markers**: repo-verified, foundation-only, later scale-layer
+- **Roadmap lane**: Later
+- **Current repo truth**: Spec 248 is already implemented as a governed AI foundation.
+- **Problem**: visible AI work must still avoid feature-island drift and should only ship on top of governed use-case, provider-class, policy, audit, and approval boundaries.
+- **Deep-Research-derived sharpening**: keep AI foundation-first. The next visible candidate is a bounded governed runtime consumer or AI-assisted review-drafting lane, not a new foundation reboot.
+- **Non-goals**: no public LLM by default, no autonomous remediation, no chatbot over raw tenant data, no AI without audit and policy boundaries.

+# Specification Quality Checklist: Cross-Tenant Promotion Execution v1
+
+**Purpose**: Validate specification completeness and repo fit before implementation  
+**Created**: 2026-05-02  
+**Feature**: [spec.md](../spec.md)
+
+## Content Quality
+
+- [x] The spec stays on one bounded follow-up over the already-implemented read-only compare and preflight slice instead of reopening portfolio compare foundations.
+- [x] The spec is product- and behavior-oriented and does not read like an implementation diff.
+- [x] The spec explicitly names the current repo-real foundations it builds on: `CrossTenantComparePage`, compare preview, promotion preflight, launch context, shared `OperationRun` UX, and current provider-write seams.
+- [x] Mandatory repo sections for scope, RBAC, disclosure, testing, operation UX, and proportionality are completed.
+
+## Requirement Completeness
+
+- [x] No `[NEEDS CLARIFICATION]` markers remain.
+- [x] Requirements are testable and bounded to one compare-page execution path.
+- [x] The spec explains what remains in scope versus what is intentionally deferred.
+- [x] Acceptance scenarios cover queueing execution, Monitoring continuity, and target-safe authorization behavior.
+- [x] Edge cases cover stale preflight, no-ready execution, active-run dedupe, inaccessible tenants, and operational-control blocking.
+
+## Candidate Selection Gate
+
+- [x] The selected candidate exists in `docs/product/spec-candidates.md` and `docs/product/roadmap.md`.
+- [x] `docs/product/implementation-ledger.md` still records promotion execution as the missing delta after compare and preflight.
+- [x] Existing Spec 043 was checked for completion and treated as inherited context only; this package is explicitly the execution follow-up, not a rewrite of the read-only slice.
+- [x] The chosen slice is smaller and higher-priority than deferred alternatives such as batch promotion, approvals, rollback, or mapping automation.
+
+## Feature Readiness
+
+- [x] The slice is an explicit delta follow-up over Spec 043 and current code, centered on one canonical compare page and one queued run path.
+- [x] The spec explicitly forbids new panel or Laravel or Filament service-provider registration changes, new global-search scope, new asset strategy, and new promotion-draft persistence.
+- [x] The spec explicitly records one canonical `promotion.execute` `OperationRun` path and shared Monitoring continuity.
+- [x] The artifacts explicitly distinguish conditional `ProviderOperationRegistry` wiring from Laravel or Filament service-provider registration.
+- [x] The spec acknowledges the current repo constraint that foreign-tenant `PolicyVersion` execution is not directly allowed and therefore requires a bounded bridge instead of a fake direct reuse claim.
+
+## Test Governance
+
+- [x] Planned validation stays bounded to `PortfolioCompare` unit and feature families plus one new bounded browser smoke file.
+- [x] One new browser smoke file is explicitly justified because the feature adds a confirmation modal and compare-to-Monitoring handoff on a live Filament page.
+- [x] The runtime proof commands stay consistent across spec, plan, and tasks, while Pint remains standard implementation hygiene.
+
+## Notes
+
+- Reviewed against `docs/product/spec-candidates.md`, `docs/product/roadmap.md`, `docs/product/implementation-ledger.md`, `specs/043-cross-tenant-compare-and-promotion/spec.md`, current PortfolioCompare code and tests under `apps/platform`, current `OperationRun` UX seams, current restore or policy-version write seams, and `.specify/memory/constitution.md` on 2026-05-02.
+- No application implementation was performed while preparing this package.
+
+## Review Outcome
+
+- **Outcome class**: `acceptable-special-case`
+- **Outcome**: `keep`
+- **Reason**: The spec promotes the next real manual backlog item after the implemented read-only compare slice, stays on one canonical compare page plus one run type, explicitly rejects draft persistence and batch drift, and only introduces one justified browser smoke addition.
+- **Workflow result**: Ready for implementation.

+# Implementation Plan: Cross-Tenant Promotion Execution v1
+
+**Branch**: `264-cross-tenant-promotion-execution` | **Date**: 2026-05-02 | **Spec**: [spec.md](./spec.md)
+**Input**: Feature specification from `/specs/264-cross-tenant-promotion-execution/spec.md`
+
+## Summary
+
+This plan is the execution delta over Spec 043 and the current cross-tenant compare code path. The existing compare page, compare preview builder, promotion preflight, launch context, and preflight audit are inherited. The implementation scope is only to add one bounded `Execute promotion` path that reuses the current compare and preflight truth, requires explicit confirmation, queues exactly one canonical `promotion.execute` `OperationRun`, and keeps result truth on the shared Monitoring path. The implementation must not add a persisted promotion-draft or compare-snapshot entity.
+
+The most important repo-truth constraint is already visible in current code: `RestoreService::executeFromPolicyVersion()` rejects foreign-tenant `PolicyVersion` records, so the execution path cannot be implemented as a naive direct call to the existing policy-version restore job. v1 therefore needs one bounded promotion execution planner or bridge that translates source-tenant content into target-safe write inputs while still delegating the actual target mutation through current provider-write seams.
+
+## Inherited Baseline / Explicit Delta
+
+### Inherited baseline
+
+- `CrossTenantComparePage` already owns the canonical `/admin/cross-tenant-compare` selection and preflight surface.
+- `CrossTenantCompareSelection`, `CrossTenantComparePreviewBuilder`, and `CrossTenantPromotionPreflight` already provide reproducible compare and readiness truth.
+- tenant-registry and portfolio launch context plus return-state continuity already work.
+- preflight audit already uses the current workspace audit pipeline.
+- current tests already prove compare preview, preflight, authorization, audit, and launch continuity.
+
+### Explicit delta in this plan
+
+- add one queued `promotion.execute` run type and the smallest supporting control, capability, and audit wiring required for it
+- add one bounded promotion execution planner or bridge that consumes the current compare and preflight truth
+- wire `Execute promotion` onto the current compare page with explicit confirmation and shared start-result UX
+- keep Monitoring continuity on the existing `OperationRun` viewer and current run-link contract
+
+## Technical Context
+
+**Language/Version**: PHP 8.4, Laravel 12, Filament v5, Livewire v4  
+**Primary Dependencies**: `CrossTenantComparePage`, `CrossTenantComparePreviewBuilder`, `CrossTenantPromotionPreflight`, `OperationRunService`, `OperationCatalog`, `OperationRunLinks`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, `WorkspaceAuditLogger`, `AuditActionId`, and the current policy-version or restore write seam  
+**Storage**: PostgreSQL tables already in use for `OperationRun`, audit logs, policy versions, inventory, and existing provider-write artifacts  
+**Testing**: Pest unit and feature tests plus one bounded browser smoke  
+**Validation Lanes**: `fast-feedback`, `confidence`, `browser`  
+**Target Platform**: existing Laravel admin runtime under `apps/platform`  
+**Project Type**: Laravel monolith with Filament admin surfaces  
+**Performance Goals**: no synchronous provider mutation from the compare page, no second queue family, and no new heavy browser or provider fixture domain  
+**Constraints**: no promotion-draft table, no compare-snapshot table, no direct foreign-tenant `PolicyVersion` execution, no multi-target batch, no approval chain, no rollback engine  
+**Scale/Scope**: one source tenant, one target tenant, one current compare scope, one queued run
+
+## UI / Surface Guardrail Plan
+
+- **Guardrail scope**: changed surfaces
+- **Native vs custom classification summary**: native Filament compare page plus shared `OperationRun` UX only
+- **Shared-family relevance**: compare-page header actions, confirmation modal, queued start feedback, run links, Monitoring continuity
+- **State layers in scope**: page state, query state, preflight state, action state, confirmation modal state, and existing run-link state
+- **Audience modes in scope**: operator-MSP only
+- **Decision/diagnostic/raw hierarchy plan**: decision-first compare summary and mutation scope first, subject-level execution diagnostics second, raw provider detail last and kept off the compare page
+- **Raw/support gating plan**: raw provider payloads, provider IDs, and worker detail remain behind existing tenant or Monitoring detail surfaces
+- **One-primary-action / duplicate-truth control**: the compare page keeps exactly one dominant next action at a time, and Monitoring remains the only progress detail surface after queueing
+- **Handling modes by drift class or surface**: `review-mandatory` for any drift toward a second promotion surface, draft persistence, or local notification flow
+- **Repository-signal treatment**: `review-mandatory`
+- **Special surface test profiles**: `standard-native-filament`
+- **Required tests or manual smoke**: focused PortfolioCompare feature coverage plus one bounded browser smoke for compare-to-operation handoff
+- **Exception path and spread control**: none; any proposal for draft persistence, approvals, rollback, or batch execution is a scope split, not an in-feature exception
+- **Active feature PR close-out entry**: Smoke Coverage
+
+## Shared Pattern & System Fit
+
+- **Cross-cutting feature marker**: yes
+- **Systems touched**: `CrossTenantComparePage`, compare preview and preflight services, operation catalog and capability wiring, current Monitoring links, audit logging, and the bounded provider-write bridge for target mutation
+- **Shared abstractions reused**: `OperationRunService`, `OperationRunLinks`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, `WorkspaceUiEnforcement`, `WorkspaceAuditLogger`, and current compare and preflight services
+- **New abstraction introduced? why?**: yes. One bounded `PortfolioCompare` execution planner or bridge is required because current restore helpers are tenant-owned and reject foreign-tenant policy versions. One queued promotion job is required because target mutation must not run synchronously on the compare page.
+- **Why the existing abstraction was sufficient or insufficient**: the current compare and preflight seam is sufficient for readiness and exclusion truth. It is insufficient for execution because it does not generate a target-safe mutation plan or a queued run identity.
+- **Bounded deviation / spread control**: keep the new logic local to the `PortfolioCompare` domain and current run UX seams. Do not create a new promotion module, workspace, or dashboard family.
+
+## OperationRun UX Impact
+
+- **Touches OperationRun start/completion/link UX?**: yes
+- **Central contract reused**: `OperationRunService`, `OperationRunLinks`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, and `OpsUxBrowserEvents`
+- **Delegated UX behaviors**: queued or deduped start messaging, blocked or scope-busy messaging, Monitoring link generation, run-enqueued browser event, and terminal notification stay on the shared run UX layer
+- **Surface-owned behavior kept local**: compare-page confirmation copy, excluded-subject explanation, and current launch or return-state preservation remain local to the compare page
+- **Queued DB-notification policy**: no new queued-only DB notification path
+- **Terminal notification path**: existing `OperationRun` completion path remains authoritative
+- **Exception path**: none
+
+## Provider Boundary & Portability Fit
+
+- **Shared provider/platform boundary touched?**: yes
+- **Provider-owned seams**: current policy-version capture, restore semantics, assignment or scope-tag handling, and provider write execution stay provider-owned
+- **Platform-core seams**: compare-page wording, run vocabulary, authorization, operational control labels, and Monitoring continuity stay platform-owned
+- **Neutral platform terms / contracts preserved**: source tenant, target tenant, governed subject, promotion execution, ready subject, blocked reason, manual mapping required
+- **Retained provider-specific semantics and why**: Microsoft-specific payload and target mutation semantics remain inside the existing provider-write seam because the repo currently has one real provider
+- **Bounded extraction or follow-up path**: if current provider-write seams cannot support a bounded bridge without widening persistence, stop and split before introducing a second promotion truth
+
+## Constitution Check
+
+*GATE: Must pass before implementation begins and again before merge.*
+
+- Inventory-first: compare preview and preflight remain derived from current tenant-owned inventory or captured content; execution consumes that truth instead of inventing a parallel catalog
+- Read/write separation: preflight stays read-only; mutation begins only after explicit confirmation and queued execution
+- Graph contract path: direct Graph or provider writes must stay behind the current provider-write seam, never in the Filament page action itself
+- Deterministic capabilities: execution stays on existing capability registries and current workspace or tenant isolation rules
+- RBAC-UX: inaccessible tenants remain `404`; execution denials remain explicit `403` only for in-scope actors forcing a blocked mutation path
+- Workspace isolation: unchanged
+- Tenant isolation: source tenant stays read-only; target tenant owns the mutation boundary
+- Run observability: exactly one canonical `promotion.execute` `OperationRun` is required
+- OperationRun start UX: shared start UX remains authoritative
+- Ops-UX lifecycle and summary counts: stay on existing `OperationSummaryKeys`; no new summary-key family
+- Test governance: keep proof bounded to PortfolioCompare unit, feature, and one browser smoke file only
+- Proportionality / persistence / bloat: no new table, no approval chain, no rollback, no draft persistence
+- Shared pattern first: current compare page and run UX must be extended, not bypassed
+- Provider boundary: use the bounded bridge only to cross the tenant-owned restore restriction; do not generalize it into a second provider abstraction layer
+- V1 explicitness / few layers: prefer one planner or bridge plus one job over a subsystem of drafts, approvals, and orchestration records
+- Filament-native UI: keep the current compare page as the only operator surface; no new panel or Laravel or Filament service-provider registration work is needed
+- UI or UX surface taxonomy and decision-first operating model: compare remains the decision surface and Monitoring remains the run viewer
+- Audience-aware disclosure: operators see readiness, mutation scope, and run link first; raw provider detail stays hidden by default
+- Action-surface discipline: the compare page keeps one dominant next action at a time

+- **Why this lane mix is the narrowest sufficient proof**: unit coverage proves plan derivation and ready-only filtering, feature coverage proves Filament action, auth, and audit behavior, and one browser smoke proves the confirmation modal plus Monitoring handoff on the real compare page
+- **Narrowest proving command(s)**:
+  - `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Unit/Support/PortfolioCompare/CrossTenantPromotionExecutionPlannerTest.php`

+- **Fixture / helper / factory / seed / context cost risks**: reuse current portfolio-compare fixtures and current `OperationRun` assertions; avoid new provider seed domains or broad Monitoring fixtures
+- **Expensive defaults or shared helper growth introduced?**: no
+- **Heavy-family additions, promotions, or visibility changes**: one new bounded browser smoke file only
+- **Surface-class relief / special coverage rule**: `standard-native-filament` with required real-browser confirmation coverage
+- **Closing validation and reviewer handoff**: reviewers should confirm that the queued path, audit trail, and Monitoring handoff all stay on shared seams with no draft persistence
+- **Budget / baseline / trend follow-up**: none
+- **Review-stop questions**: lane fit, no-draft persistence, run type or control naming, and bounded target-write bridge only
+- **Escalation path**: none
+- **Active feature PR close-out entry**: Smoke Coverage

+
+**Structure Decision**: keep the implementation inside the current compare page, `PortfolioCompare` support or service layer, and current `OperationRun` UX seams. Add at most one bounded planner or bridge, one execution service, and one queued job.
+
+## Data / Migration Implications
+
+- Prefer existing `OperationRun.context`, `OperationRun.summary_counts`, and audit metadata over new persistence.
+- No new table or migration is expected for v1.
+- If operation or control naming needs only PHP registry changes, keep it there and avoid schema work.
+- If implementation cannot bridge source content into target-safe mutation inputs without a new persisted promotion-draft or snapshot entity, stop and split the feature rather than widening the current package.
+
+## Rollout Considerations
+
+- Filament remains v5 on Livewire v4. No new Laravel or Filament service-provider registration change is required, and service-provider registration remains in `apps/platform/bootstrap/providers.php`.
+- No global search change is required because the affected surface is an existing page and the Monitoring viewer is already in place.
+- No new asset registration is expected.
+- The new mutating action is not destructive in the delete sense, but it must still use explicit confirmation on the compare page.
+- Existing queue workers remain the deployment requirement for the new run path.
+
+## Risk Controls
+
+- Reject any implementation that persists promotion drafts, compare snapshots, or approval records.
+- Reject any implementation that reuses `RestoreService::executeFromPolicyVersion()` by pretending the source version belongs to the target tenant.
+- Reject any implementation that introduces a second promotion surface, a second queue domain, or a promotion-specific dashboard.
+- Reject any implementation that invents new run-summary keys instead of staying on canonical keys.
+- Keep blocked and manual-mapping-required subjects excluded from target mutation in all paths.
+
+## Implementation Phases
+
+### Phase 0 - Confirm the bounded execution seam
+
+- Reconfirm the current compare and preflight truth plus the current restore restriction that foreign-tenant `PolicyVersion` execution is not directly allowed.
+- Decide the smallest target-safe bridge from source content to target write inputs without adding persistence.
+
+### Phase 1 - Add operation vocabulary and bounded execution planning
+
+- Add one canonical `promotion.execute` operation type, its control key, run capability mapping, any `ProviderOperationRegistry` entry only if the chosen shared start-result seam requires it, and audit action IDs.
+- Add one bounded planner or bridge that derives ready-only execution inputs and stable run identity values from the current compare and preflight truth.
+
+`ProviderOperationRegistry` remains application operation-vocabulary wiring only. It is not Laravel or Filament service-provider registration.
+
+### Phase 2 - Wire the compare page action and shared start UX
+
+- Add `Execute promotion` to the current compare page with explicit confirmation, single-primary-action discipline, and preserved source, target, and return-state context.
+- Reuse shared start-result UX for queued, deduped, blocked, and Monitoring-link behaviors.
+
+### Phase 3 - Execute the target mutation through one queued run
+
+- Add one queued promotion execution job that consumes `OperationRun.context`, delegates actual writes through current provider-write seams, and records summary counts using canonical keys only.
+- Keep the compare page free of synchronous target mutation.
+
+### Phase 4 - Audit, Monitoring continuity, and stop
+
+- Record start and terminal audit metadata for promotion execution.
+- Ensure Monitoring links, related navigation, and labels remain canonical for the new run type.
+- Run the planned validation commands and stop without widening into drafts, approval flow, rollback, or batch execution.
+
+## Why This Plan Is Narrow Enough
+
+The repo already has the compare page, preflight truth, audit path, queue infrastructure, and Monitoring viewer. This plan adds only the missing bounded execution seam: one confirmed page action, one run type, one ready-only execution planner or bridge, and one queued worker. Everything larger stays explicitly deferred.

+# Feature Specification: Cross-Tenant Promotion Execution v1
+
+**Feature Branch**: `264-cross-tenant-promotion-execution`
+**Created**: 2026-05-02
+**Status**: Ready for implementation
+**Input**: User description: "Cross-Tenant Promotion Execution v1"
+
+## Inherited Baseline / Explicit Delta
+
+This package is an explicit delta follow-up over Spec 043 and the current cross-tenant compare code path.
+
+### Inherited baseline
+
+- `CrossTenantComparePage` already owns the canonical `/admin/cross-tenant-compare` decision surface.
+- `CrossTenantCompareSelection`, `CrossTenantComparePreviewBuilder`, and `CrossTenantPromotionPreflight` already produce reproducible read-only compare and readiness truth.
+- tenant-registry launch context, exact-two compare launch, and return-state preservation already exist.
+- preflight audit already lands on the existing workspace audit pipeline through `AuditActionId::CrossTenantPromotionPreflightGenerated`.
+- the current slice is intentionally read-only and explicitly deferred actual promotion execution, queueing, `OperationRun`, persisted compare snapshots, persisted promotion drafts, mapping automation, and customer-facing compare.
+
+### Explicit delta in this spec
+
+- add one bounded `Execute promotion` action from the current compare and preflight context
+- require explicit confirmation before any target mutation starts
+- queue exactly one canonical `OperationRun` for promotion execution and reuse the shared start/result UX
+- mutate the target tenant for `ready` subjects only while keeping `blocked` and `manual_mapping_required` subjects excluded and visible
+- keep execution truth on existing `OperationRun` and audit records instead of adding a new promotion-draft or compare-snapshot table
+
+Everything broader remains inherited or explicitly out of scope.
+
+## Spec Candidate Check *(mandatory - SPEC-GATE-001)*
+
+- **Problem**: The product can already compare tenants and generate a read-only promotion preflight, but operators still cannot execute the bounded promotion step that the page recommends.
+- **Today's failure**: Cross-tenant compare ends at advice. Operators still need manual, off-platform steps to apply source settings to the target tenant and then separately reconstruct whether the action actually ran.
+- **User-visible improvement**: An authorized workspace operator can review a current compare preflight, confirm the scope, queue one cross-tenant promotion run, and follow that run through the existing Monitoring flow without leaving the canonical compare page.
+- **Smallest enterprise-capable version**: One compare-page execution action, one confirmation modal, one queued `OperationRun`, one bounded promotion execution planner and worker, one truthful Monitoring handoff, and explicit audit metadata. No draft persistence, no batch execution, and no rollback workflow ship in v1.
+- **Explicit non-goals**: No persisted promotion draft entity, no scheduled or recurring promotion, no multi-target batch execution, no approval workflow, no rollback engine, no customer-facing promotion, no cross-workspace execution, and no multi-provider abstraction expansion.
+- **Permanent complexity imported**: One bounded execution planner or bridge, one queued promotion job, one new canonical operation type plus control key, a small audit extension, and focused unit, feature, and browser proof.
+- **Why now**: `docs/product/spec-candidates.md`, `docs/product/roadmap.md`, and `docs/product/implementation-ledger.md` all still identify execution as the missing follow-up after the already-implemented read-only compare and preflight slice.
+- **Why not local**: A page-local mutation button without a shared run contract would bypass the current compare truth, safety gates, audit seams, and Monitoring continuity.
+- **Approval class**: Core Enterprise
+- **Red flags triggered**: New mutating action, new queued run type, new write bridge over an existing read-only workflow. Defense: the slice stays on one compare page, one target tenant, one run type, zero new tables, and existing provider write seams.
+- **Score**: Nutzen: 2 | Dringlichkeit: 2 | Scope: 1 | Komplexitaet: 1 | Produktnaehe: 2 | Wiederverwendung: 2 | **Gesamt: 10/12**
+- **Decision**: approve
+
+## Spec Scope Fields *(mandatory)*
+
+- **Scope**: canonical-view
+- **Primary Routes**:
+  - existing canonical `/admin/cross-tenant-compare` page for selection, preflight review, and execution confirmation
+  - existing `/admin/tenants` registry or portfolio-triage launch surfaces as the compare entrypoint and return context
+  - existing Monitoring operation-run detail flow as the canonical follow-up after a promotion run is queued
+- **Data Ownership**:
+  - source-of-truth remains the current compare preview, preflight result, source-tenant `PolicyVersion` or equivalent captured content, and target-tenant inventory or restore truth
+  - runtime truth remains on `OperationRun`, current audit logs, and existing provider-write artifacts; no `CrossTenantPromotionDraft`, compare snapshot, or promotion-plan table is introduced
+  - any execution context must live in `OperationRun.context`, `OperationRun.summary_counts`, and audit metadata only
+- **RBAC**:
+  - workspace and tenant scoping stay deny-as-not-found first for out-of-scope actors or tenants
+  - compare viewing keeps the existing 043 requirements: workspace baselines view plus tenant view on both source and target
+  - execution requires the compare-view permissions plus `Capabilities::WORKSPACE_BASELINES_MANAGE` on the workspace and `Capabilities::TENANT_MANAGE` on the target tenant
+  - source-tenant access stays read-only (`Capabilities::TENANT_VIEW`); the mutation boundary is the target tenant only
+  - members who can view compare but cannot execute still see the execution affordance only where the page already stays decision-oriented, and that affordance must be disabled with explicit permission guidance while forced execution attempts return `403`
+  - no new promotion-specific capability family may be introduced in v1
+
+For canonical-view specs, the spec MUST define:
+
+- **Default filter behavior when tenant-context is active**: registry and portfolio launches continue to prefill the launched tenant as the `target tenant`, preserve the return-state token, and keep the `source tenant` intentionally chosen by the operator unless the current exact-two launch path already supplies both tenants.
+- **Explicit entitlement checks preventing cross-tenant leakage**: the page must re-resolve workspace membership, source tenant scope, target tenant scope, and execution capability before preflight or execution logic runs. Any inaccessible tenant input is treated as not found, and no `OperationRun` may be created from inaccessible or stale selection input.
+
+## Cross-Cutting / Shared Pattern Reuse *(mandatory when the feature touches notifications, status messaging, action links, header actions, dashboard signals/cards, navigation entry points, evidence/report viewers, or any other existing shared operator interaction family; otherwise write `N/A - no shared interaction family touched`)*
+
+- **Cross-cutting feature?**: yes
+- **Interaction class(es)**: compare-page header actions, confirmation modal copy, queued start notifications, Monitoring links, run status messaging, audit metadata, and return-state continuity
+- **Systems touched**: `CrossTenantComparePage`, tenant-registry launch context, `CrossTenantCompareSelection`, `CrossTenantComparePreviewBuilder`, `CrossTenantPromotionPreflight`, `OperationRunService`, `OperationCatalog`, `OperationRunType`, `OperationRunLinks`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, `OpsUxBrowserEvents`, `WorkspaceAuditLogger`, `AuditActionId`, `OperationalControlCatalog`, and the current policy-version or restore write seam
+- **Existing pattern(s) to extend**: canonical compare page, current portfolio launch and return-state contract, shared `OperationRun` start UX, and existing Monitoring deep-link semantics
+- **Shared contract / presenter / builder / renderer to reuse**: `CanonicalNavigationContext`, `WorkspaceUiEnforcement`, `OperationRunService`, `OperationRunLinks`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, `OpsUxBrowserEvents`, and the existing compare preview and preflight builders
+- **Operation-registry distinction**: any `ProviderOperationRegistry` update in v1 is app-level operation-vocabulary wiring only, and only if the chosen shared start-result seam requires it. It is not Laravel or Filament service-provider registration.
+- **Why the existing shared path is sufficient or insufficient**: compare and preflight already solve the selection and blocked-reason truth. They are insufficient for v1 execution because they do not produce a queued run, start/result UX, or target mutation plan. The current restore and policy-version seams solve provider write behavior and run lifecycle, but they are tenant-owned and cannot be pointed at a foreign tenant without a bounded promotion bridge.
+- **Allowed deviation and why**: none. The feature must extend the current compare page and shared run UX instead of creating a second promotion console or a promotion-specific dashboard.
+- **Consistency impact**: the terms `source tenant`, `target tenant`, `promotion preflight`, `Execute promotion`, `ready`, `blocked`, `manual mapping`, and `Open operation` must stay consistent across compare copy, confirmation copy, audit summaries, notifications, and Monitoring labels.
+- **Review focus**: reviewers must block any persisted draft entity, direct Graph write from the page action, or local notification/run-link flow that bypasses the shared `OperationRun` UX contract.
+
+## OperationRun UX Impact *(mandatory when the feature creates, queues, deduplicates, resumes, blocks, completes, or deep-links to an `OperationRun`; otherwise write `N/A - no OperationRun start or link semantics touched`)*
+
+- **Touches OperationRun start/completion/link UX?**: yes
+- **Shared OperationRun UX contract/layer reused**: `OperationRunService`, `OperationRunLinks`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, and `OpsUxBrowserEvents`
+- **Delegated start/completion UX behaviors**: queued toast, deduped-or-already-running messaging, blocked or scope-busy result messaging, canonical Monitoring link generation, run-enqueued browser event dispatch, and normal terminal notification handling stay delegated to the shared run UX layer
+- **Local surface-owned behavior that remains**: compare selection state, preflight summary, excluded-subject explanation, and confirmation-modal wording remain owned by `CrossTenantComparePage`
+- **Queued DB-notification policy**: no new queued-only database-notification policy is introduced; v1 relies on the compare-page start result plus the existing terminal notification path
+- **Terminal notification path**: keep the existing initiator-aware `OperationRun` completion path
+- **Exception required?**: none
+
+## Provider Boundary / Platform Core Check *(mandatory when the feature changes shared provider/platform seams, identity scope, governed-subject taxonomy, compare strategy selection, provider connection descriptors, or operator vocabulary that may leak provider-specific semantics into platform-core truth; otherwise write `N/A - no shared provider/platform boundary touched`)*
+
+- **Shared provider/platform boundary touched?**: yes
+- **Boundary classification**: mixed
+- **Seams affected**: compare selection to execution planning, source content resolution, target mutation bridge, operation vocabulary, and provider-backed write delegation
+- **Neutral platform terms preserved or introduced**: `source tenant`, `target tenant`, `governed subject`, `promotion execution`, `ready subject`, `blocked reason`, and `manual mapping required`
+- **Provider-specific semantics retained and why**: Microsoft-first policy types, assignment semantics, scope tags, and provider payload translation remain inside the current policy-version, restore, and provider write seams because the repo currently has one real provider domain
+- **Why this does not deepen provider coupling accidentally**: the page contract stays anchored on compare and preflight truth, and the queued mutation delegates into existing provider-write paths instead of exposing Graph-specific inputs or raw payload editing in the page surface
+- **Follow-up path**: multi-provider promotion remains a separate follow-up if it ever becomes current-release truth
+
+## UI / Surface Guardrail Impact *(mandatory when operator-facing surfaces are changed; otherwise write `N/A`)*
+
+| Surface / Change | Operator-facing surface change? | Native vs Custom | Shared-Family Relevance | State Layers Touched | Exception Needed? | Low-Impact / `N/A` Note |
+|---|---|---|---|---|---|---|
+| Canonical cross-tenant compare page | yes | Native Filament page plus shared compare and ops-ux primitives | compare summary, confirmation modal, run-start UX, Monitoring link continuity | page, query state, preflight state, action state, confirmation modal state | no | Reuses the current compare page; no second promotion surface is allowed |
+| Tenant registry / portfolio launch action | no | N/A | current launch context only | none beyond existing deep-link state | no | Launch behavior remains inherited from Spec 043 |
+| Monitoring operation-run detail | no | N/A | existing shared operation-run viewer | none beyond normal new-type rendering | no | v1 reuses the existing Monitoring viewer rather than introducing a promotion-specific detail screen |
+
+## Decision-First Surface Role *(mandatory when operator-facing surfaces are changed)*
+
+| Surface | Decision Role | Human-in-the-loop Moment | Immediately Visible for First Decision | On-Demand Detail / Evidence | Why This Is Primary or Why Not | Workflow Alignment | Attention-load Reduction |
+|---|---|---|---|---|---|---|---|
+| Canonical cross-tenant compare page | Primary Decision Surface | Operator decides whether the ready portion of the current source selection should mutate the target tenant now | source and target summary, ready or blocked counts, exclusion counts, mutation scope, and the single next action | subject-level execution plan, mapping gaps, target exclusions, source and target drill-down links, and current run link after queueing | Primary because the compare page already owns the trusted preflight truth and can keep the execution decision tied to that truth | Moves directly from compare to confirmation to queued Monitoring handoff without a second workspace | Replaces off-platform handoff and manual note-taking with one bounded action path |
+
+## Audience-Aware Disclosure *(mandatory when operator-facing surfaces are changed)*
+
+| Surface | Audience Modes In Scope | Decision-First Default-Visible Content | Operator Diagnostics | Support / Raw Evidence | One Dominant Next Action | Hidden / Gated By Default | Duplicate-Truth Prevention |
+|---|---|---|---|---|---|---|---|
+| Canonical cross-tenant compare page | operator-MSP | source and target summary, preflight counts, excluded-subject totals, mutation scope, and current run link if a run exists | subject-level ready plan, mapping gaps, evidence freshness, and target-safe exclusions | raw provider payloads and deep provider diagnostics stay behind existing tenant, inventory, or Monitoring detail surfaces | `Generate promotion preflight` before eligibility, then `Execute promotion` after a current executable preflight exists | raw JSON, provider IDs, worker internals, and low-level payload diffs | the compare page owns readiness truth once; the confirmation modal restates only the mutation scope, and Monitoring owns run progress after queueing |
+
+## UI/UX Surface Classification *(mandatory when operator-facing surfaces are changed)*
+
+| Surface | Action Surface Class | Surface Type | Likely Next Operator Action | Primary Inspect/Open Model | Row Click | Secondary Actions Placement | Destructive Actions Placement | Canonical Collection Route | Canonical Detail Route | Scope Signals | Canonical Noun | Critical Truth Visible by Default | Exception Type / Justification |
+|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
+| Canonical cross-tenant compare page | Utility / Workspace Decision | Queued execution decision | Execute promotion | explicit selectors plus focused compare or preflight panels and confirmation modal | forbidden | open-source, open-target, return, and open-operation links stay secondary | none; `Execute promotion` is mutating but not destructive and must still use confirmation | `/admin/cross-tenant-compare` | same page with shareable query state and current run handoff | workspace context plus source and target tenant chips | Cross-tenant compare | whether the ready part of the current source selection can be promoted now and what will be excluded | none |
+
+## Operator Surface Contract *(mandatory when operator-facing surfaces are changed)*
+
+| Surface | Primary Persona | Decision / Operator Action Supported | Surface Type | Primary Operator Question | Default-visible Information | Diagnostics-only Information | Status Dimensions Used | Mutation Scope | Primary Actions | Dangerous Actions |
+|---|---|---|---|---|---|---|---|---|---|---|
+| Canonical cross-tenant compare page | Workspace operator / MSP operator | Decide whether to queue a bounded promotion run against the target tenant | Canonical decision page | Can I safely apply the ready part of this source selection to the target tenant now, and what will be left out? | source and target summary, ready or blocked counts, manual-mapping and blocked totals, mutation scope, confirmation summary, and latest run handoff | subject-level execution plan, mapping gaps, source and target drill-downs, and follow-up hints | compare readiness, execution availability, and run state | Microsoft tenant target only | Generate promotion preflight, Execute promotion, Open operation, Open source tenant, Open target tenant | Execute promotion (requires confirmation) |
+
+## Proportionality Review *(mandatory when structural complexity is introduced)*
+
+- **New source of truth?**: no
+- **New persisted entity/table/artifact?**: no
+- **New abstraction?**: yes - one bounded promotion execution planner or bridge plus one queued promotion job
+- **New enum/state/reason family?**: yes - one new canonical operation type and one operational control key, but no new persisted lifecycle family or draft state family
+- **New cross-domain UI framework/taxonomy?**: no
+- **Current operator problem**: compare and preflight prove readiness, but operators still cannot execute the bounded next step or observe the result from the same truth.
+- **Existing structure is insufficient because**: the current compare slice stops before any `OperationRun`, and the current `RestoreService::executeFromPolicyVersion()` explicitly rejects foreign-tenant versions, so the execution path cannot be implemented as a naive direct call.
+- **Narrowest correct implementation**: derive a ready-only execution plan from the current compare and preflight truth, queue one target-tenant-scoped `promotion.execute` run, and translate source content into target-safe write inputs through an existing provider-write seam without introducing draft persistence.
+- **Ownership cost**: maintain one new operation vocabulary entry, one bounded execution bridge, one queued worker, small audit metadata expansion, and focused tests.
+- **Alternative intentionally rejected**: persisted promotion drafts, scheduled promotions, approval chains, and cross-tenant batch execution are intentionally rejected because they import new truth and operator workflow before the bounded execution seam is proven.
+- **Release truth**: current-release workflow gap, not a future-state platform ambition
+
+### Compatibility posture
+
+This feature assumes a pre-production environment.
+
+Backward compatibility, migration shims, and legacy workflow preservation remain out of scope unless the implementation discovers a concrete repo-owned compatibility contract that the current spec missed.
+
+Canonical replacement is preferred over parallel promotion workflows.
+
+## Testing / Lane / Runtime Impact *(mandatory for runtime behavior changes)*
+
+- **Test purpose / classification**: Unit, Feature, Browser
+- **Validation lane(s)**: fast-feedback, confidence, browser
+- **Why this classification and these lanes are sufficient**: unit coverage proves ready-only execution planning and no-draft behavior, focused feature coverage proves page action, authorization, audit, and Monitoring handoff, and one bounded browser smoke proves the confirmation modal and compare-to-operation handoff on the real Filament surface.
+- **New or expanded test families**: `tests/Unit/Support/PortfolioCompare/`, `tests/Feature/PortfolioCompare/`, and one new bounded `tests/Browser/PortfolioCompare/` smoke file
+- **Fixture / helper cost impact**: moderate; reuse the existing portfolio-compare fixtures, current workspace and tenant setup, and current `OperationRun` assertions rather than introducing a new provider or browser fixture domain
+- **Heavy-family visibility / justification**: one new browser smoke file is justified because the feature adds a confirmation modal and Monitoring handoff on a live Filament page
+- **Special surface test profile**: standard-native-filament
+- **Standard-native relief or required special coverage**: ordinary feature coverage is sufficient for the compare and run-start contract, but the final compare-page handoff to Monitoring must be proven once in the browser
+- **Reviewer handoff**: reviewers must confirm the slice stays on one compare page, one run type, zero new draft tables, and shared run UX only
+- **Budget / baseline / trend impact**: low to moderate; one new browser smoke file and one new operation type only
+- **Escalation needed**: none
+- **Active feature PR close-out entry**: Smoke Coverage
+- **Planned validation commands**:
+  - `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Unit/Support/PortfolioCompare/CrossTenantPromotionExecutionPlannerTest.php`
+  - `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionActionTest.php tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuthorizationTest.php tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuditTest.php tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionRunUxTest.php tests/Feature/PortfolioCompare/CrossTenantComparePageTest.php tests/Feature/PortfolioCompare/CrossTenantCompareLaunchContextTest.php`
+  - `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Browser/PortfolioCompare/CrossTenantPromotionExecutionSmokeTest.php`
+  - `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
+
+## Scope Boundaries
+
+### In Scope
+
+- one `Execute promotion` action on the canonical compare page after a current preflight exists
+- one explicit confirmation modal that names the source tenant, target tenant, ready counts, excluded counts, and mutation scope
+- one queued `promotion.execute` `OperationRun`
+- one bounded execution planner or bridge that translates ready subjects into target-safe write inputs
+- one truthful Monitoring handoff and run-link continuity
+- start and terminal audit metadata for the promotion execution path
+- compare-page continuity after queueing, including preserved source, target, and return-state context
+
+### Non-Goals
+
+- persisted compare snapshots or promotion-draft tables
+- scheduled or recurring promotion execution
+- approval workflows or multi-actor sign-off
+- rollback or undo workflows
+- multi-target or batch promotion
+- mapping automation for manual-mapping-required subjects
+- customer-facing promotion surfaces
+- cross-workspace execution
+- multi-provider execution frameworks
+
+## Assumptions
+
+- the current compare and preflight contracts expose enough stable subject identity to resolve a bounded ready-only execution plan
+- the current provider-write seams can accept a target-safe execution payload once the source content is normalized through a bounded bridge
+- the existing Monitoring viewer can represent the new run type without a dedicated promotion detail resource
+- current queue workers already provide the runtime model needed for one more `OperationRun`-backed promotion job
+
+## Risks
+
+- some subjects marked `ready` by preflight may still fail at execution time because the current target write seam discovers provider constraints later than the read-only preflight can
+- the promotion bridge may be tempted to persist a new draft or snapshot entity; that must be rejected unless a separate follow-up spec is created
+- run-summary truth can drift if the implementation invents non-canonical summary keys instead of staying on the current `OperationSummaryKeys` set
+- a future implementation could try to broaden the slice into approval, rollback, or batch execution; that is out of scope for this spec
+
+## Follow-up Candidates
+
+- manual mapping workflow for `manual_mapping_required` subjects
+- portfolio-level batch promotion across many targets
+- approval or sign-off gating before execution
+- rollback or replay workflow after a promotion run completes
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - Queue one bounded promotion from the current preflight (Priority: P1)
+
+As a workspace operator, I want to confirm and queue one bounded promotion from the current compare and preflight context so I can apply only the ready subjects to the target tenant without manual off-platform execution.
+
+**Why this priority**: This is the core value gap left by Spec 043. Without queueable execution, compare remains advisory only.
+
+**Independent Test**: Open the compare page with an executable preflight, confirm the action, and verify that one `promotion.execute` run is queued with ready subjects only.
+
+**Acceptance Scenarios**:
+
+1. **Given** the current preflight contains a mix of `ready`, `blocked`, and `manual_mapping_required` subjects, **When** the operator confirms `Execute promotion`, **Then** only the `ready` subjects enter the queued run context and the excluded subjects remain visible on the compare page.
+2. **Given** the current selection and preflight produce no `ready` subjects, **When** the operator tries to execute promotion, **Then** the action is blocked and no `OperationRun` is created.
+3. **Given** an active run already exists for the same source, target, subject scope, and executable plan, **When** the operator tries to execute again, **Then** the shared start UX dedupes or reuses the current run instead of creating a second active run.
+
+---
+
+### User Story 2 - Follow the queued promotion through Monitoring with truthful result summary (Priority: P1)
+
+As a workspace operator, I want a canonical run link and truthful result summary after I queue a promotion so I can monitor completion and know what happened without leaving the existing Monitoring path.
+
+**Why this priority**: Execution is unsafe if the operator cannot observe start, progress, and terminal outcome on the existing shared Monitoring path.
+
+**Independent Test**: Queue a promotion run from the compare page and verify that the start result, Monitoring link, and run-summary truth all stay on the shared `OperationRun` contract.
+
+**Acceptance Scenarios**:
+
+1. **Given** a promotion run is successfully queued, **When** the compare page receives the start result, **Then** the operator sees the shared queued feedback and one canonical `Open operation` link.
+2. **Given** the promotion run reaches a terminal state, **When** the operator opens the Monitoring detail, **Then** the run summary clearly distinguishes processed, succeeded, failed, and skipped work using the shared summary-key vocabulary.
+3. **Given** the run start is blocked by operational control, legitimacy, or target-scoped gating, **When** the operator attempts execution, **Then** they receive the shared blocked feedback and no target mutation begins.
+
+---
+
+### User Story 3 - Preserve portfolio context and execution safety boundaries (Priority: P2)
+
+As a workspace operator, I want the execution path to preserve my compare and return-state context while still enforcing target-safe capability and control boundaries so the workflow stays usable and safe inside the portfolio review loop.
+
+**Why this priority**: The workflow loses value if the operator must rebuild compare context after queueing or if the page hides the reasons why execution is unavailable.
+
+**Independent Test**: Launch compare from the tenant registry, queue or attempt to queue promotion, and verify that source, target, return-state, and safety boundaries all remain intact.
+
+**Acceptance Scenarios**:
+
+1. **Given** the operator launched compare from a registry or portfolio context, **When** they queue a promotion, **Then** the compare page preserves the source tenant, target tenant, governed-subject filters, and return-state continuity.
+2. **Given** the operator can view compare but lacks target-tenant manage or workspace baseline-manage access, **When** they reach an otherwise executable compare state, **Then** execution stays visible only as a disabled safety-gated affordance and any forced execution attempt returns `403`.
+3. **Given** the source or target tenant becomes inaccessible or stale between preflight and confirmation, **When** the operator attempts execution, **Then** the request is rejected and no `OperationRun` is created.
+
+### Edge Cases
+
+- source and target tenant are the same tenant: reject as invalid input and do not queue a run
+- preflight is stale because the compare selection changed after it was generated: require regeneration and do not queue a run
+- no ready subjects remain after current truth is re-evaluated at execution time: fail safe and do not queue or start target mutation
+- the existing provider-write seam cannot resolve a target-safe payload from the source subject: mark the item failed or skipped inside the run; do not invent a draft state family
+- operational control or legitimacy gate blocks `promotion.execute`: surface the shared blocked message and keep the compare state intact
+
+## Requirements *(mandatory)*
+
+### Functional Requirements
+
+- **FR-001**: The canonical `/admin/cross-tenant-compare` page must remain the only operator entrypoint for v1 promotion execution.
+- **FR-002**: Promotion execution must require a current compare preview and a current promotion preflight before queueing any target mutation.
+- **FR-003**: The page must expose exactly one dominant next action at a time: `Generate promotion preflight` before readiness exists, then `Execute promotion` once the current preflight is executable.
+- **FR-004**: `Execute promotion` must require explicit confirmation and must name the source tenant, target tenant, count of ready subjects, count of excluded subjects, and the target-only mutation scope.
+- **FR-005**: Only `ready` subjects from the current preflight may enter the queued execution plan; `blocked` and `manual_mapping_required` subjects must stay excluded from the run and visible to the operator.
+- **FR-006**: The execution path must create or reuse exactly one canonical `OperationRun` for the current executable plan, using one new canonical operation type for promotion execution.
+- **FR-007**: The feature must keep execution truth on existing `OperationRun` state, summary counts, and audit metadata only. No persisted promotion-draft, compare-snapshot, or approval entity may be added.
+- **FR-008**: The run-start path must reuse the shared `OperationRun` start UX contract for queued, deduped, blocked, and Monitoring-link behaviors.
+- **FR-009**: The implementation must not pretend that a source-tenant `PolicyVersion` belongs to the target tenant. Any bridge from source content to target mutation must preserve tenant-owned truth while still reusing existing provider-write semantics.
+- **FR-010**: Run summary counts must stay on canonical summary keys only. Promotion-specific meaning must be expressed through page or Monitoring copy, not a new summary-key family.
+- **FR-011**: The feature must record start and terminal audit events for promotion execution with source-tenant, target-tenant, selection, and outcome context.
+- **FR-012**: Compare and launch context must remain preserved after queueing, including source tenant, target tenant, governed-subject filters, and return-state payload.
+- **FR-013**: Execution authorization must require workspace baseline-manage and target-tenant manage in addition to the existing compare-view permissions.
+- **FR-014**: Filament must remain v5 on Livewire v4, and Laravel or Filament service-provider registration must remain unchanged in `apps/platform/bootstrap/providers.php`.
+- **FR-015**: No new panel, no new asset registration, no new Laravel or Filament service-provider registration work, and no new globally searchable resource may be introduced for this slice.
+
+### Key Entities *(include if feature involves data)*
+
+- **Cross-tenant compare selection**: existing derived scope of source tenant, target tenant, and governed-subject filters; remains read-only input truth.
+- **Promotion preflight**: existing derived readiness artifact grouping subjects into `ready`, `blocked`, and `manual_mapping_required`; becomes the only allowed execution source.
+- **Promotion execution plan**: new bounded in-memory or `OperationRun.context` representation of the ready-only mutation plan; not a persisted standalone entity.
+- **Promotion execution run**: one canonical `OperationRun` using the new operation type and existing Monitoring viewer.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: An authorized operator can move from current compare preflight to a queued `promotion.execute` run without leaving the canonical compare page.
+- **SC-002**: The compare page never queues blocked or manual-mapping-required subjects for target mutation.
+- **SC-003**: The queued run can be opened through the shared Monitoring path and exposes truthful processed, succeeded, failed, and skipped counts.
+- **SC-004**: The implementation ships without a persisted promotion-draft table, second promotion surface, or second queue family.

+
+# Tasks: Cross-Tenant Promotion Execution v1
+
+**Input**: Design documents from `specs/264-cross-tenant-promotion-execution/`  
+**Prerequisites**: `specs/264-cross-tenant-promotion-execution/spec.md`, `specs/264-cross-tenant-promotion-execution/plan.md`, `specs/264-cross-tenant-promotion-execution/checklists/requirements.md`
+
+**Tests**: REQUIRED (Pest plus one bounded Browser smoke). Keep proof bounded to `PortfolioCompare` unit and feature families plus one new `Browser/PortfolioCompare` smoke file only.
+**Operations**: Introduce one canonical `promotion.execute` `OperationRun` type and reuse the shared `OperationRun` start UX, Monitoring links, and current provider-write seams. No promotion-draft table, no compare-snapshot table, no second queue family, and no second promotion dashboard are allowed.
+**RBAC**: Non-members and out-of-scope tenants remain `404`. Compare-view permissions stay inherited from Spec 043. Execution adds target-tenant manage plus workspace baseline-manage enforcement, with disabled affordance guidance and server-side `403` on forced execution. No new capability family may be introduced.
+**Shared Pattern Reuse**: Reuse `CrossTenantComparePage`, current launch and return context, `CrossTenantComparePreviewBuilder`, `CrossTenantPromotionPreflight`, `OperationRunService`, `OperationUxPresenter`, `ProviderOperationStartResultPresenter`, `OperationRunLinks`, `OpsUxBrowserEvents`, `WorkspaceAuditLogger`, `AuditActionId`, and current provider-write seams. Do not create persisted promotion drafts or a local run-start UX.
+**Filament / Panel Guardrails**: Filament remains v5 on Livewire v4. Laravel or Filament service-provider registration remains unchanged in `apps/platform/bootstrap/providers.php`. No new panel, no new globally searchable resource, and no new asset strategy are allowed.
+**Organization**: Tasks are grouped by user story so the execution contract, Monitoring continuity, and safety boundaries remain independently testable and implementable. This package is an explicit delta follow-up over Spec 043 and current code.
+
+## Test Governance Checklist
+
+- [x] Lane assignment stays `fast-feedback`, `confidence`, plus one bounded `browser` smoke and remains the narrowest sufficient proof.
+- [x] New or changed tests stay in `apps/platform/tests/Unit/Support/PortfolioCompare/`, `apps/platform/tests/Feature/PortfolioCompare/`, and one new `apps/platform/tests/Browser/PortfolioCompare/` smoke file only.
+- [x] Existing portfolio-compare fixtures and current `OperationRun` assertions are reused; no new heavy provider or browser fixture domain is introduced.
+- [x] Planned validation commands stay consistent across spec, plan, and tasks.
+- [x] The declared surface test profile remains `standard-native-filament` with explicit real-browser confirmation coverage.
+- [x] Any drift toward persisted drafts, approvals, rollback, or batch promotion is handled as `reject-or-split` rather than hidden inside this feature.
+
+## Phase 1: Setup (Shared Context)
+
+**Purpose**: Confirm the current compare, preflight, run UX, and provider-write seams before any implementation change.
+
+- [x] T001 Review `specs/264-cross-tenant-promotion-execution/spec.md`, `specs/264-cross-tenant-promotion-execution/plan.md`, `specs/264-cross-tenant-promotion-execution/checklists/requirements.md`, `specs/043-cross-tenant-compare-and-promotion/spec.md`, `docs/product/spec-candidates.md`, `docs/product/roadmap.md`, and `docs/product/implementation-ledger.md` together so the slice stays on the current execution gap only.
+- [x] T002 [P] Confirm the current compare-page and launch-context seams in `apps/platform/app/Filament/Pages/CrossTenantComparePage.php`, `apps/platform/tests/Feature/PortfolioCompare/CrossTenantComparePageTest.php`, and `apps/platform/tests/Feature/PortfolioCompare/CrossTenantCompareLaunchContextTest.php`.
+- [x] T003 [P] Confirm the current compare-preview and preflight seams in `apps/platform/app/Support/PortfolioCompare/CrossTenantComparePreviewBuilder.php`, `apps/platform/app/Support/PortfolioCompare/CrossTenantPromotionPreflight.php`, and the current PortfolioCompare test coverage.
+- [x] T004 [P] Confirm the current shared run-start, Monitoring-link, and operation-vocabulary seams in `apps/platform/app/Services/OperationRunService.php`, `apps/platform/app/Support/OperationCatalog.php`, `apps/platform/app/Support/OperationRunType.php`, `apps/platform/app/Support/OperationRunLinks.php`, `apps/platform/app/Support/Operations/OperationRunCapabilityResolver.php`, `apps/platform/app/Support/OperationalControls/OperationalControlCatalog.php`, and `apps/platform/app/Services/Providers/ProviderOperationRegistry.php` only to determine whether app-level operation-registry wiring is required by the chosen shared start-result seam.
+- [x] T005 [P] Confirm the current target-write seam and its constraints in `apps/platform/app/Services/Intune/RestoreService.php`, `apps/platform/app/Jobs/BulkPolicyVersionRestoreJob.php`, and `apps/platform/app/Jobs/Operations/PolicyVersionRestoreWorkerJob.php`, especially the current rule that foreign-tenant policy versions cannot be executed directly.
+
+---
+
+## Phase 2: Foundational (Blocking Prerequisites)
+
+**Purpose**: Lock the bounded execution contract before surface-level implementation begins.
+
+**Critical**: No user-story work should begin until this phase is complete.
+
+- [x] T006 [P] Add `apps/platform/tests/Unit/Support/PortfolioCompare/CrossTenantPromotionExecutionPlannerTest.php` to require ready-only execution planning, blocked and manual exclusion, stable run-identity inputs, and no-ready rejection.
+- [x] T007 [P] Add `apps/platform/tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuthorizationTest.php` to require `404` for out-of-scope tenants, disabled execution affordance for compare-only actors, and `403` for forced execution without target-manage or workspace-manage access.
+- [x] T008 [P] Add `apps/platform/tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionRunUxTest.php` to require one canonical `promotion.execute` run type, shared start-result statuses, and active-run dedupe for the same executable plan.
+- [x] T009 Implement the foundational execution contract in `apps/platform/app/Support/OperationCatalog.php`, `apps/platform/app/Support/OperationRunType.php`, `apps/platform/app/Support/Operations/OperationRunCapabilityResolver.php`, `apps/platform/app/Support/OperationalControls/OperationalControlCatalog.php`, `apps/platform/app/Services/Providers/ProviderOperationRegistry.php` only if the shared start-result seam requires app-level operation-registry wiring, `apps/platform/app/Support/Audit/AuditActionId.php`, and the bounded `PortfolioCompare` execution planner or bridge chosen for v1 so the feature has one canonical operation vocabulary and no draft persistence. No `ProviderOperationRegistry` change was required because the shared start-result seam worked through the existing presenter/link contract.
+
+**Checkpoint**: The canonical run vocabulary, control wiring, audit ids, and ready-only execution plan are locked before page and job work begins.
+
+---
+
+## Phase 3: User Story 1 - Queue one bounded promotion from the current preflight (Priority: P1)
+
+**Goal**: An authorized operator can confirm and queue a target mutation for ready subjects only from the current compare and preflight context.
+
+**Independent Test**: Open the compare page, generate a preflight with ready work, confirm `Execute promotion`, and verify that one `promotion.execute` run is queued with ready subjects only.
+
+### Tests for User Story 1
+
+- [x] T010 [P] [US1] Add `apps/platform/tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionActionTest.php` to assert that preflight is required, only ready subjects enter the queued run context, blocked and manual subjects stay excluded, and no-ready execution is blocked.
+- [x] T011 [P] [US1] Extend `apps/platform/tests/Feature/PortfolioCompare/CrossTenantComparePageTest.php` only where needed to prove the compare page keeps one dominant next action at a time and does not regress the current same-tenant or stale-selection safeguards once execution exists.
+
+### Implementation for User Story 1
+
+- [x] T012 [US1] Add one bounded `PortfolioCompare` execution planner or bridge plus one execution service in `apps/platform/app/Support/PortfolioCompare/` and or `apps/platform/app/Services/PortfolioCompare/` that translates the current ready subjects into target-safe mutation inputs without creating a persisted promotion draft.
+- [x] T013 [US1] Update `apps/platform/app/Filament/Pages/CrossTenantComparePage.php` so the page exposes `Execute promotion` with explicit confirmation, preserves one-primary-action discipline, and keeps source, target, governed-subject filters, and return-state context intact after queueing.
+- [x] T014 [US1] Add one queued promotion execution job under `apps/platform/app/Jobs/Operations/` that consumes `OperationRun.context`, performs target mutation for ready subjects only, and records canonical summary counts (`total`, `processed`, `succeeded`, `failed`, `skipped`, `created`, `updated`) instead of inventing a new summary-key family.
+
+**Checkpoint**: The canonical compare page can queue one bounded target mutation without persisting a draft or mutating blocked subjects.
+
+---
+
+## Phase 4: User Story 2 - Follow the queued promotion through Monitoring with truthful run UX (Priority: P1)
+
+**Goal**: The operator receives shared queued feedback, one canonical Monitoring link, and truthful run summary after starting a promotion.
+
+**Independent Test**: Queue a promotion run from the compare page and verify that the start result, Monitoring link, and run-summary truth all stay on the shared `OperationRun` contract.
+
+### Tests for User Story 2
+
+- [x] T015 [P] [US2] Extend `apps/platform/tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionRunUxTest.php` to assert queued, deduped, blocked, and Monitoring-link outcomes plus canonical run-context fields for the new operation type.
+- [x] T016 [P] [US2] Add `apps/platform/tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuditTest.php` to assert queued and terminal audit metadata and the absence of any persisted promotion-draft or compare-snapshot writes.
+- [x] T017 [P] [US2] Add `apps/platform/tests/Browser/PortfolioCompare/CrossTenantPromotionExecutionSmokeTest.php` to prove the live compare page can move from generated preflight to confirmation to queued `Open operation` handoff without breaking the existing action hierarchy.
+
+### Implementation for User Story 2
+
+- [x] T018 [US2] Wire the shared start-result UX through `apps/platform/app/Services/OperationRunService.php`, `apps/platform/app/Support/OperationRunLinks.php`, `apps/platform/app/Support/OpsUx/OperationUxPresenter.php`, `apps/platform/app/Services/Providers/ProviderOperationStartResultPresenter.php`, and `apps/platform/app/Support/OpsUx/OpsUxBrowserEvents.php` so compare-page execution uses canonical queued, deduped, blocked, and run-link messaging. No additional `OperationRunService` or `OperationUxPresenter` changes were required beyond compare-page reuse of the shared presenter, link, and browser-event seams.
+- [x] T019 [US2] Extend `apps/platform/app/Support/OperationRunLinks.php`, `apps/platform/app/Support/Navigation/RelatedNavigationResolver.php`, and any minimal Monitoring label surface only as needed so `promotion.execute` opens the current Monitoring viewer without a promotion-specific detail screen. Existing `OperationRunLinks::tenantlessView()` continuity already satisfied this path without further runtime changes.
+- [x] T020 [US2] Extend `apps/platform/app/Services/Audit/WorkspaceAuditLogger.php` and `apps/platform/app/Support/Audit/AuditActionId.php` only as needed so promotion execution records start and terminal audit truth with source-tenant, target-tenant, selection, and outcome metadata.
+
+**Checkpoint**: The execution path starts, dedupes, blocks, links, and audits on the shared `OperationRun` seams only.
+
+---
+
+## Phase 5: User Story 3 - Preserve portfolio context and safety boundaries (Priority: P2)
+
+**Goal**: Execution preserves compare and return-state context while enforcing target-safe control and capability boundaries.
+
+**Independent Test**: Launch compare from the tenant registry, queue or attempt to queue a promotion, and verify that source, target, return-state, and safety boundaries all remain intact.
+
+### Tests for User Story 3
+
+- [x] T021 [P] [US3] Extend `apps/platform/tests/Feature/PortfolioCompare/CrossTenantCompareLaunchContextTest.php` to prove queued promotion keeps source-tenant, target-tenant, governed-subject, and return-state continuity. The stable proof now uses the mounted compare-page instance on the exact-two registry launch path, which avoids the flaky secondary Livewire snapshot hop while still exercising the same launched page state and queued promotion contract.
+- [x] T022 [P] [US3] Extend `apps/platform/tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuthorizationTest.php` only where needed to prove stale-preflight, operational-control, and inaccessible-tenant execution attempts never create a run.
+
+### Implementation for User Story 3
+
+- [x] T023 [US3] Preserve compare-page launch and return context after queueing, and add any secondary `Open operation` continuity only where it does not compete with the primary action. No additional runtime change was required in the bounded slice beyond the existing compare-page state handling and shared operation link seams; T021 now provides the explicit queued launch-context continuity proof.
+- [x] T024 [US3] Integrate operational-control and legitimacy blocking for `promotion.execute` so blocked, stale, or inaccessible execution attempts fail safely without widening into approvals, rollback, or batch controls.
+
+**Checkpoint**: The execution path stays usable inside the portfolio workflow and still fails closed at every safety boundary.
+
+---
+
+## Phase 6: Polish & Cross-Cutting Validation
+
+**Purpose**: Validate the bounded slice and stop without widening scope.
+
+- [x] T025 [P] Run `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Unit/Support/PortfolioCompare/CrossTenantPromotionExecutionPlannerTest.php`.
+- [x] T026 [P] Run `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionActionTest.php tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuthorizationTest.php tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionAuditTest.php tests/Feature/PortfolioCompare/CrossTenantPromotionExecutionRunUxTest.php tests/Feature/PortfolioCompare/CrossTenantComparePageTest.php tests/Feature/PortfolioCompare/CrossTenantCompareLaunchContextTest.php`.
+- [x] T027 [P] Run `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Browser/PortfolioCompare/CrossTenantPromotionExecutionSmokeTest.php`.
+- [x] T028 [P] Run `export PATH="/bin:/usr/bin:/usr/local/bin:$PATH" && cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`.
+- [x] T029 [P] Review touched code to confirm Filament stays on Livewire v4, Laravel or Filament service-provider registration remains unchanged in `apps/platform/bootstrap/providers.php`, no globally searchable resource contract changes appear, and the mutating compare-page action uses explicit confirmation.
+- [x] T030 [P] Review touched code to confirm the feature introduces no promotion-draft persistence, no compare-snapshot persistence, no second queue family, no second promotion surface, no approval workflow, and no rollback workflow.
+- [x] T031 [P] Record the final guardrail, smoke, and scope-boundary outcomes in the active feature close-out without reopening batch promotion, approvals, rollback, or multi-provider follow-up work.

+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Phase 1 (Setup)**: no dependencies; start immediately.
+- **Phase 2 (Foundational)**: depends on Phase 1 and blocks all user stories.
+- **Phase 3 (US1)**: depends on Phase 2 and establishes the bounded execution path.
+- **Phase 4 (US2)**: depends on Phase 2 and should land with US1 so the start-result UX and Monitoring truth do not drift from the queued path.
+- **Phase 5 (US3)**: depends on Phase 2 and hardens context and safety behavior after the execution path exists.
+- **Phase 6 (Polish)**: depends on all desired user stories being complete.
+
+### User Story Dependencies
+
+- **US1 (P1)**: independently testable after Phase 2 and delivers the core execution value.
+- **US2 (P1)**: independently testable after Phase 2 and should ship with US1 so the operator gets truthful Monitoring handoff.
+- **US3 (P2)**: independently testable after Phase 2 and hardens the bounded execution path.
+
+### Within Each User Story
+
+- Write the listed Pest coverage first and make it fail for the intended gap.
+- Keep implementation inside the compare page, bounded `PortfolioCompare` execution seam, shared `OperationRun` UX, and current provider-write paths named above.
+- Re-run the narrowest relevant validation command after each story checkpoint before moving on.
+
+---
+
+## Implementation Strategy
+
+### Suggested MVP Scope
+
+- MVP = **US1 + US2 together**. The feature is only useful when the compare page can both queue promotion and hand the operator into truthful Monitoring continuity.
+
+### Incremental Delivery
+
+1. Complete Phase 1 and Phase 2.
+2. Deliver US1 and US2 together on the current compare page and shared run UX.
+3. Add US3 to keep return-state and safety boundaries intact.
+4. Finish with the focused validation and guardrail review tasks in Phase 6.
+
+### Team Strategy
+
+1. Settle the bounded execution bridge first.
+2. Parallelize failing tests within each story before runtime edits.
+3. Serialize merges around `CrossTenantComparePage`, operation-catalog wiring, and shared Monitoring links so operator vocabulary stays coherent.
+
+---
+
+## Deferred Follow-Ups / Non-Goals
+
+- persisted promotion drafts or compare snapshots
+- approval workflow before execution
+- rollback or replay workflow after execution
+- batch or multi-target promotion
+- automated manual-mapping resolution
+- customer-facing promotion surfaces
+- multi-provider execution framework
