+
+# Browser Smoke Test
+
+## What This Skill Does
+
+Use this skill to validate the current feature end-to-end in the integrated browser.
+
+This is a focused smoke test, not a full exploratory test session. The goal is to prove that the primary operator flow:
+
+- loads in the correct auth, workspace, and tenant context
+- exposes the expected controls and decision points
+- completes the main happy path without blocking issues
+- lands in the expected end state or canonical drilldown
+- does not show obvious regressions such as broken navigation, missing data, or conflicting actions
+
+The skill should produce a concrete pass or fail result with actionable evidence.
+
+## When To Apply
+
+Activate this skill when:
+
+- the user asks to smoke test the current feature in the browser
+- a new Filament page, dashboard signal, report, wizard, or detail flow was just added
+- a UI regression fix needs confirmation in a real browser context
+- the primary question is whether the feature works from an operator perspective
+- you need a quick integration-level check without writing a full browser test suite first
+
+## What Success Looks Like
+
+A successful smoke test confirms all of the following:
+
+- the target route opens successfully
+- the visible context is correct
+- the main flow is usable
+- the expected result appears after interaction
+- the route or drilldown destination is correct
+- the surface does not obviously violate its intended interaction model
+
+If the test cannot be completed, the output must clearly state whether the blocker is:
+
+- authentication
+- missing data or fixture state
+- routing
+- UI interaction failure
+- server error
+- an unclear expected behavior contract
+
+Do not guess. If the route or state is blocked, report the blocker explicitly.
+
+## Preconditions
+
+Before running the browser smoke test, make sure you know:
+
+- the canonical route or entry point for the feature
+- the primary operator action or happy path
+- the expected success state
+- whether the feature depends on a specific tenant, workspace, or seeded record
+
+When available, use the feature spec, quickstart, tasks, or current browser page as the source of truth.
+
+## Standard Workflow
+
+### 1. Define the smoke-test scope
+
+Identify:
+
+- the route to open
+- the primary action to perform
+- the expected end state
+- one or two critical regressions that must not break
+
+The smoke test should stay narrow. Prefer one complete happy path plus one critical boundary over broad exploratory clicking.
+
+### 2. Establish the browser state
+
+- Reuse the current browser page if it already matches the target feature.
+- Otherwise open the canonical route.
+- Confirm the current auth and scope context before interacting.
+
+For this repo, that usually means checking whether the page is on:
+
+- `/admin/...` for workspace-context surfaces
+- `/admin/t/{tenant}/...` for tenant-context surfaces
+
+### 3. Inspect before acting
+
+- Use `read_page` before interacting so you understand the live controls, refs, headings, and route context.
+- Prefer `read_page` over screenshots for actual interaction planning.
+- Use screenshots only for visual evidence or when the user asks for them.
+
+### 4. Execute the primary happy path
+
+Run the smallest meaningful flow that proves the feature works.
+
+Typical steps include:
+
+- open the page
+- verify heading or key summary text
+- click the primary CTA or row
+- fill the minimum required form fields
+- confirm modal or dialog text when relevant
+- submit or navigate
+- verify the expected destination or changed state
+
+After each meaningful action, re-read the page so the next step is based on current DOM state.
+
+### 5. Validate the outcome
+
+Check the exact result that matters for the feature.
+
+Examples:
+
+- a new row appears
+- a status changes
+- a success message appears
+- a report filter changes the result set
+- a row click lands on the canonical detail page
+- a dashboard signal links to the correct report page
+
+### 6. Check for obvious regressions
+
+Even in a smoke test, verify a few core non-negotiables:
+
+- the page is not blank or half-rendered
+- the main action is present and usable
+- the visible context is correct
+- the drilldown destination is canonical
+- no obviously duplicated primary actions exist
+- no stuck modal, spinner, or blocked interaction remains onscreen
+
+### 7. Capture evidence and summarize clearly
+
+Your result should state:
+
+- route tested
+- context used
+- steps executed
+- pass or fail
+- exact blocker or discrepancy if failed
+
+Include a screenshot only when it adds value.
+
+## Tool Usage Guidance
+
+Use the browser tools in this order by default:
+
+1. `read_page`
+2. `click_element`
+3. `type_in_page`
+4. `handle_dialog` when needed
+5. `navigate_page` or `open_browser_page` only when route changes are required
+6. `run_playwright_code` only if the normal browser tools are insufficient
+7. `screenshot_page` for evidence, not for primary navigation logic
+
+## Repo-Specific Guidance For TenantPilot
+
+### Workspace surfaces
+
+For `/admin` pages and similar workspace-context surfaces:
+
+- verify the page is reachable without forcing tenant-route assumptions
+- confirm any summary signal or CTA lands on the canonical destination
+- verify calm-state versus attention-state behavior when the feature defines both
+
+### Tenant surfaces
+
+For `/admin/t/{tenant}/...` pages:
+
+- verify the tenant context is explicit and correct
+- verify drilldowns stay in the intended tenant scope
+- treat cross-tenant leakage or silent scope changes as failures
+
+### Filament list or report surfaces
+
+For Filament tables, reports, or registry-style pages:
+
+- verify the heading and table shell render
+- verify fixed filters or summary controls exist when the spec requires them
+- verify row click or the primary inspect affordance behaves as designed
+- verify empty-state messaging is specific rather than generic when the feature defines custom behavior
+
+### Filament detail pages
+
+For detail or view surfaces:
+
+- verify the canonical record loads
+- verify expected sections or summary content are present
+- verify critical actions or drillbacks are usable
+
+## Result Format
+
+Use a compact result format like this:
+
+```text
+Browser smoke result: PASS
+Route: /admin/findings/hygiene
+Context: workspace member with visible hygiene issues
+Steps: opened report -> verified filters -> clicked finding row -> landed on canonical finding detail
+Verified: report rendered, primary interaction worked, drilldown route was correct
+```
+
+If the test fails:
+
+```text
+Browser smoke result: FAIL
+Route: /admin/findings/hygiene
+Context: authenticated workspace member
+Failed step: clicking the summary CTA
+Expected: navigate to /admin/findings/hygiene
+Actual: remained on /admin with no route change
+Blocker: CTA appears rendered but is not interactive
+```
+
+## Examples
+
+### Example 1: Smoke test a new report page
+
+Use this when the feature adds a new read-only report.
+
+Steps:
+
+- open the canonical report route
+- verify the page heading and main controls
+- confirm the table or defined empty state is visible
+- click one row or primary inspect affordance
+- verify navigation lands on the canonical detail route
+
+Pass criteria:
+
+- report loads
+- intended controls exist
+- primary inspect path works
+
+### Example 2: Smoke test a dashboard signal
+
+Use this when the feature adds a summary signal on `/admin`.
+
+Steps:
+
+- open `/admin`
+- find the signal
+- verify the visible count or summary text
+- click the CTA
+- confirm navigation lands on the canonical downstream surface
+
+Pass criteria:
+
+- signal is visible in the correct state
+- CTA text is present
+- CTA opens the correct route
+
+### Example 3: Smoke test a tenant detail follow-up
+
+Use this when a workspace-level surface should drill into a tenant-level detail page.
+
+Steps:
+
+- open the workspace-level surface
+- trigger the drilldown
+- verify the target route includes the correct tenant and record
+- confirm the target page actually loads the expected detail content
+
+Pass criteria:
+
+- drilldown route is canonical
+- tenant context is correct
+- destination content matches the selected record
+
+## Common Pitfalls
+
+- Clicking before reading the page state and refs
+- Treating a blocked auth session as a feature failure
+- Confusing workspace-context routes with tenant-context routes
+- Reporting visual impressions without validating the actual interaction result
+- Forgetting to re-read the page after a modal opens or a route changes
+- Claiming success without verifying the final destination or changed state
+
+## Non-Goals
+
+This skill does not replace:
+
+- full exploratory QA
+- formal Pest browser coverage
+- accessibility review
+- visual regression approval
+- backend correctness tests
+
+It is a fast, real-browser confidence pass for the current feature.

 - Direct mapping from canonical domain truth to UI is preferred over intermediate semantic superstructures.
 - Presentation helpers SHOULD remain optional adapters, not mandatory architecture.
 
+### Shared Pattern First For Cross-Cutting Interaction Classes (XCUT-001)
+- Cross-cutting interaction classes such as notifications, status messaging, action links, header actions, dashboard signals/cards, navigation entry points, alerts, evidence/report viewers, and similar operator-facing infrastructure MUST first attach to an existing shared contract, presenter, builder, renderer, or other shared path when one already exists.
+- New local or domain-specific implementations for an existing interaction class are allowed only when the current shared path is demonstrably insufficient for current-release truth.
+- The active spec MUST name the shared path being reused or explicitly record the deviation, why the existing path is insufficient, what consistency must still be preserved, and what ownership or spread-control cost the deviation creates.
+- The same interaction class MUST NOT develop parallel operator-facing UX languages for title/body/action structure, status semantics, action-label patterns, or deep-link behavior unless the deviation is explicit and justified.
+- Reviews MUST treat undocumented bypass of an existing shared path as drift and block merge until the feature converges on the shared path or records a bounded exception.
+- If the drift is discovered only after a feature is already implemented, the remedy is NOT to rewrite historical closed specs retroactively by default; instead the active work MUST record the issue as `document-in-feature` or escalate it as `follow-up-spec`, depending on whether the drift is contained or structural.
+
 ### V1 Prefers Explicit Narrow Implementations (V1-EXP-001)
 - For V1 and early product maturity, direct implementation, local mapping, explicit per-domain logic, small focused helpers, derived read models, and minimal UI adapters are preferred.
 - Generic platform engines, meta-frameworks, universal resolver systems, workflow frameworks, and broad semantic taxonomies are disfavored until real variance proves them necessary.

 - **Priority**: high
 
+> Architecture contract-enforcement cluster: these candidates come from the targeted repository drift audit on 2026-04-22. Most are intentionally narrower than naming, presentation, or IA cleanup work. The shared contracts already exist; the gap is that they are not yet treated as mandatory on every platform-owned path.

+
+### Operation Run Link Contract Enforcement
+- **Type**: hardening / contract enforcement
+- **Source**: targeted repository architecture/pattern-drift audit 2026-04-22; canonical operation-link drift review
+- **Problem**: TenantPilot already has a real canonical navigation contract in `OperationRunLinks` and `SystemOperationRunLinks`, but platform-owned UI and shared layers can still build `OperationRun` links through raw `route('admin.operations...')` calls. The same navigation class is therefore emitted through two parallel paths, including in shared navigation layers that otherwise already know the canonical link contract.
+- **Why it matters**: This is not a missing-helper problem. It is a shared-contract bypass on a cross-cutting operator path. If it keeps spreading, tenant/workspace context, filter continuity, deep-link stability, and future operations IA changes all become more expensive because each surface can choose raw routes instead of the contract.
+- **Proposed direction**:
+  - inventory platform-owned `OperationRun` collection/detail link producers and classify legitimate infrastructure exceptions
+  - move platform-owned UI and shared navigation layers to `OperationRunLinks` or `SystemOperationRunLinks`
+  - make collection/detail/context semantics part of the helper contract rather than repeated local route assembly
+  - add a lightweight guardrail that catches new raw `route('admin.operations...')` calls outside an explicit allowlist
+- **Explicit non-goals**: Not a new operations IA, not a redesign of the operations pages, not a broad routing refactor for the whole repo, and not a change to `OperationRun` page content.
+- **Boundary with Operation Run Active-State Visibility & Stale Escalation**: Active-state visibility owns lifecycle communication on compact and detail surfaces. This candidate owns canonical link generation and context continuity.
+- **Boundary with Operator Presentation & Lifecycle Action Hardening**: Presentation hardening owns labels, badges, and action-visibility conventions. This candidate owns deep-link and collection-link contract enforcement.
+- **Dependencies**: `OperationRunLinks`, `SystemOperationRunLinks`, canonical operations pages, and any repository signal or review guardrail infrastructure introduced by Spec 201.

+### Canonical Operation Type Source of Truth
+- **Type**: hardening / source-of-truth decision
+- **Source**: strict read-only legacy / compatibility audit 2026-04-22; operation-type drift review
+- **Problem**: The repo still carries two competing operation-type languages. `OperationCatalog` and several UI or read-model paths prefer canonical dotted names, while persistence, runtime writes, tests, registries, and supporting services still rely on historical underscore values. This is no longer just a thin alias shim; it is parallel semantic truth.
+- **Why it matters**: This is now the strongest active compatibility debt in the repo. As long as underscore and dotted forms remain co-equal in specs, code, filters, registries, and tests, every new operation type or execution surface can reinforce drift instead of converging on one contract.
+- **Goal**: Define one repo-wide normative operation-type language and make explicit which form is persisted, written, resolved at boundaries, and reflected in specs, resources, and tests.
+- **In scope**:
+  - explicit decision between underscore and dotted operation-type language as repo-wide truth
+  - normative persistence, write, read, and resolution contract for operation types
+  - cleanup or narrowing of the current alias matrix in `OperationCatalog`
+  - convergence of `OperationCatalog`, `OperationRunType`, resources, supporting services, specs, and tests
+  - guardrails that prevent new dual-semantics operation types from being introduced without an explicit exit path
+- **Out of scope**: cosmetic label-only renaming, generic repo-wide naming cleanup outside operation types, provider identity redesign, and Baseline Scope V2.
+- **Key requirements**:
+  - exactly one normative operation-type language must exist
+  - the persisted and written truth must be explicit rather than inferred
+  - underscore and dotted forms must not remain permanent parallel truths
+  - any remaining compatibility boundary must be explicit, narrow, and exit-bounded
+  - specs, code, resources, and tests must converge on the same contract
+- **Boundary with Operations Naming Harmonization Across Run Types, Catalog, UI, and Audit**: naming harmonization owns visible operator vocabulary and naming grammar. This candidate owns the underlying semantic and persistence contract for operation types.
+- **Boundary with Operator Presentation & Lifecycle Action Hardening**: presentation hardening owns operator-facing labels and badges. This candidate owns the operation-type truth that capability, triage, provider, and related behavior decisions depend on.
+- **Dependencies**: `OperationCatalog`, `OperationRunType`, capability/triage/provider decision points, operation resources and link helpers, and any repository guardrail infrastructure introduced by Spec 201.
+- **Strategic sequencing**: Third step of the repository cleanup strand, after `Dead Transitional Residue Cleanup` and `Onboarding State Fallback Retirement`.

+### Platform Vocabulary Boundary Enforcement for Governed Subject Keys
+- **Type**: hardening / platform-boundary clarification
+- **Source**: targeted repository architecture/pattern-drift audit 2026-04-22; governed-subject vocabulary drift review
+- **Problem**: The repo already treats `policy_type` as compatibility vocabulary rather than active platform language, yet platform-visible query keys, page state, filters, and read-model builders still expose `policy_type` alongside or instead of governed-subject terms. Legacy terminology therefore survives not just in storage or adapters, but in platform-visible boundaries.
+- **Why it matters**: This undercuts the repo's own vocabulary migration contract. Contributors and operators continue to read an Intune-shaped key as active platform language even where the platform already has canonical governed-subject terms.
+- **Proposed direction**:
+  - inventory platform-visible uses of `policy_type` and adjacent legacy keys in query/state/read-model boundaries
+  - distinguish allowed compatibility or storage boundaries from platform-visible vocabulary surfaces
+  - move platform-visible filter/state/query/read-model contracts to canonical governed-subject terminology
+  - preserve legacy input compatibility only through explicit normalizers or adapters
+  - add a guardrail that catches new platform-visible legacy key exposure outside allowed boundary zones
+- **Explicit non-goals**: Not a full storage-column rename sweep, not a broad Intune debranding project, not a full governance-taxonomy redesign, and not a generic repo-wide terminology cleanup campaign.
+- **Boundary with Spec 202 (Governance Subject Taxonomy)**: Spec 202 defines the taxonomy and canonical governed-subject vocabulary. This candidate enforces which keys are allowed to remain platform-visible at runtime boundaries.
+- **Boundary with Spec 204 (Platform Core Vocabulary Hardening)**: If Spec 204 remains the active vocabulary-hardening vehicle, this candidate should be absorbed as the governed-subject boundary-enforcement slice rather than promoted as a second parallel vocabulary spec.
+- **Dependencies**: Spec 202, `PlatformVocabularyGlossary`, `PlatformSubjectDescriptorNormalizer`, and the baseline/governance builder surfaces that currently expose platform-visible legacy keys.
+- **Strategic sequencing**: Third of this cluster. It should follow the operations contract-enforcement work unless Spec 204 is revived sooner and absorbs it directly.
+- **Priority**: high
+
+> Recommended sequence for this cluster:
+> 1. **Operation Run Link Contract Enforcement**
+> 2. **Canonical Operation Type Source of Truth**
+> 3. **Platform Vocabulary Boundary Enforcement for Governed Subject Keys**

+### Findings Notification Presentation Convergence
+- **Type**: workflow hardening / cross-cutting presentation
+- **Source**: Spec 224 follow-up review 2026-04-22; shared notification-pattern drift analysis
+- **Problem**: Spec 224 closed the functional delivery gap for findings notifications, but the current in-app findings path appears to compose its presentation locally instead of fully extending the existing shared operator-facing notification presentation path. The result is not a second transport stack, but a second presentation path for the same interaction type.
+- **Why it matters**: Notifications are part of TenantPilot's operator-facing decision system, not just incidental UI. If findings notifications keep a local presentation language while operation or run notifications follow a different shared path, the product accumulates UX drift, duplicated payload semantics, and a higher risk that future alerts, assignment reminders, risk-acceptance renewals, and later `My Work` entry surfaces will grow another parallel path instead of converging.
+- **Proposed direction**:
+  - inventory the current in-app / database-notification presentation paths and explicitly separate delivery/routing, stored payload, presentation contract, and deep-link semantics
+  - define one repo-internal shared presentation contract for operator-facing database notifications that covers at least title, body, tone or status, icon, primary action, deep link, and optional supporting context
+  - align findings in-app notifications to that shared path without changing the delivery semantics, recipient resolution, dedupe or fingerprint logic, or optional external-copy behavior introduced by Spec 224
+  - add contract-level regression tests and guardrail notes so future notification types extend the shared presentation path instead of building local Filament payloads directly
+- **Explicit non-goals**: Not a redesign of the alerting or routing system. Not a remodelling of external notification targets or alert rules. Not a full `My Work` or inbox implementation. Not an immediate full-sweep unification of every historical notification class in the repo. Not a rewrite of escalation rules or notification-content priority.

 - **Vehicle**: new standalone candidate
-- **Problem**: TenantPilot now has an explicit roadmap direction toward BSI-/NIS2-/CIS-oriented readiness views and executive review packs, but it still lacks the bounded domain foundation that those outputs should consume. There is no explicit, versioned model for external framework sources, TenantPilot's technical interpretation of those controls, customer/MSP profile variants, or the mapping from controls to evidence, evaluation rules, and manual attestations. Without that foundation, framework support will predictably drift into hardcoded report logic, one-off service rules, and special-case exports. The same underlying governance evidence will be translated differently per feature, and changes to framework source versions, TenantPilot interpretation logic, or customer profile overrides will become impossible to track independently.
-- **Why it matters**: This is the difference between "framework-themed reports" and a sustainable compliance-readiness product. Enterprise and MSP buyers do not need TenantPilot to become a certification engine, but they do need repeatable, reviewable, version-aware mappings from governance evidence to framework-oriented control statements. A shared control-model foundation avoids three long-term failure modes: duplicated rule logic across multiple readiness/report features, inability to explain which product interpretation produced a given readiness result, and brittle customer-specific customizations that fork framework behavior instead of profiling it. If the product wants BSI/NIS2/CIS views later, it should first know which control source version, which TenantPilot interpretation version, and which customer profile produced each answer.
+- **Layer position**: **S1** — normative control core
+- **Problem**: TenantPilot already has a real governance engine across baseline profiles, baseline capture and compare, drift findings, findings workflow, exceptions, alerts, stored reports, evidence items, and tenant review packs, but it still lacks the shared canonical object those features should point at. Today the product risks modeling control meaning in three competing places: framework-specific overlays such as NIS2, BSI, ISO, or COBIT mappings; Microsoft service- or subject-specific lists such as Entra, Intune, Exchange, or Purview subjects; or feature-local assumptions embedded separately in baseline, drift, findings, evidence, and report logic. Without a framework-neutral canonical control catalog, the same technical control objective will be duplicated, evidence and control truth will blur together, and later readiness or reporting work will inherit inconsistent semantics.
+- **Why it matters**: This is the missing structural bridge between the current governance engine and later compliance-readiness overlays. Operators, customers, and auditors need one stable answer to "what control is this about?" before the platform can credibly say which Microsoft subjects support it, which evidence proves it, which findings violate it, or which frameworks map to it. A canonical control layer prevents framework duplication, keeps control, evidence, finding, exception, and report semantics aligned, and lets the product communicate detectability honestly instead of over-claiming technical verification.
 - **Proposed direction**:
-  - Introduce a bounded compliance domain model with explicit concepts for framework registry, framework versions, control catalog entries, TenantPilot interpretation records, customer/MSP profiles, profile overrides, control-to-evidence mappings, evaluation rules, and manual attestations
-  - Separate three independent version layers: framework source version, TenantPilot interpretation version, and customer/MSP profile version
-  - Allow each control to declare automation posture such as fully automatable, partially automatable, manual-attestation-required, or outside-product-scope
-  - Map one control to multiple evidence sources and evaluation rules, and allow one evidence source to support multiple controls
-  - Treat risk exceptions, findings, stored reports, and readiness views as downstream consumers of the control model rather than the place where framework logic lives
-  - Prefer pack/import-based control lifecycle management with preview, diff, activate, archive, and migration semantics over manual per-control CRUD as the primary maintenance path
-  - Start with lightweight, product-owned control metadata and interpretation summaries rather than assuming full storage of normative framework text inside the product
+  - Introduce a framework-neutral canonical control catalog centered on control themes and objectives rather than framework clauses or raw Microsoft API objects
+  - Define canonical domains and subdomains plus stable product-wide control keys that outlive individual APIs, workloads, or framework versions
+  - Classify each control by control class, detectability class, evaluation strategy, evidence archetypes, and artifact suitability for baseline, drift, findings, exceptions, reports, and evidence packs
+  - Add a Microsoft subject-binding layer that links one canonical control to supported subject families, workloads, and signals without collapsing the control model into service-specific schema mirrors
+  - Start with a deliberately small seed catalog of high-value tenant-near control families such as strong authentication, conditional access, privileged access exposure, guest or cross-tenant boundaries, endpoint compliance and hardening, sharing boundaries, mail protection, audit retention, data protection readiness, and delegated admin boundaries
+  - Make baseline profiles, compare and drift, findings, exceptions, stored reports, and evidence items able to reference a `canonical_control_key` or equivalent control-family contract instead of each feature inventing local control meaning
+  - Keep framework mappings as a later overlay: prepare mapping structure now if useful, but do not make NIS2, BSI, ISO, COBIT, or similar frameworks the primary shape of the foundation
 - **Scope boundaries**:
-  - **In scope**: framework registry/version model, control catalog foundation, interpretation/profile/override model, evidence and evaluation mapping model, manual attestation linkage, framework-pack import and diff lifecycle, bounded admin/registry surfaces where required to manage activation state and profile variants
-  - **Out of scope**: formal certification claims, legal/compliance advice, full framework-text publishing, comprehensive support for every control in every standard, broad stakeholder-facing reporting UI, one-off PDF generation, posture scoring models, or replacing the evidence domain with a second artifact store
+  - **In scope**: canonical control vocabulary, domain and subdomain taxonomy, stable canonical keys, detectability and evaluation classifications, evidence archetypes, Microsoft subject binding model, a small seed catalog for priority control families, and integration contracts for baseline, findings, exceptions, evidence, and reports
+  - **Out of scope**: full framework catalogs, full NIS2, BSI, ISO, COBIT, or similar mappings, exhaustive Microsoft service coverage, giant control-library breadth, a full attestation engine, stakeholder-facing readiness or report UI, posture scoring models, or replacing the evidence domain with a second artifact store

-  - Not a hardcoded per-framework report generator
+  - Not a framework-first registry where the same control is duplicated once per standard

+  - The platform can represent canonical domains, subdomains, and controls with stable keys independent of framework source versions
+  - Every seed control declares control class, detectability class, evaluation strategy, and at least one evidence archetype
+  - Every seed control can declare whether it is baseline-capable, drift-capable, finding-capable, exception-capable, and report or evidence-pack-capable
+  - The model can bind one canonical control to multiple Microsoft subject families or signal sources without redefining the control per workload
+  - Baselines, findings, evidence, exceptions, and later readiness or reporting work have a defined path to consume the canonical control layer instead of hardcoding local control semantics
+  - The foundation can explicitly represent controls that are direct-technical, indirect-technical, workflow-attested, or external-evidence-only without collapsing them into one false compliant/non-compliant path
+- **Boundary with Spec 202 (Governance Subject Taxonomy and Baseline Scope V2)**: Spec 202 defines governed-subject vocabulary and baseline-scope input contracts. This candidate defines the higher-order canonical control objects that can bind to those subject families and later unify baseline, findings, evidence, and reporting semantics above raw governed-subject lists.
+- **Boundary with Evidence Domain Foundation**: Evidence Domain Foundation owns evidence capture, completeness, freshness, and immutable artifacts. This candidate owns the canonical control definitions those evidence artifacts can support and the detectability and evaluation semantics that explain what the evidence means.
+- **Boundary with Spec 154 (Finding Risk Acceptance Lifecycle)**: Risk Acceptance owns the lifecycle for approved deviations once a finding or control gap exists. This candidate owns the stable control object that exceptions and compensating-control semantics should refer to.
+- **Boundary with CIS Baseline Library**: The CIS library owns reusable template packs and benchmark libraries built on top of canonical controls. This candidate owns the control ontology itself and must not absorb CIS-specific expected-state packs into the normative control core.
+- **Boundary with Compliance Readiness & Executive Review Packs**: Compliance Readiness owns stakeholder-facing framework and readiness views plus report packaging. This candidate owns the framework-neutral control core those later views should map onto instead of inventing per-framework local logic.
+- **Dependencies**: Spec 202 (governed-subject vocabulary), Spec 153 (evidence-domain-foundation) for evidence-contract alignment, Spec 154 (finding-risk-acceptance), baseline and drift foundations, and downstream stored-report or review-pack consumers
+- **Related specs / candidates**: Spec 153 (evidence-domain-foundation), Spec 154 (finding-risk-acceptance), Spec 155 (tenant-review-layer), Spec 202 (governance-subject-taxonomy), CIS Baseline Library, Compliance Readiness & Executive Review Packs, Security Posture Signals Foundation, Entra Role Governance, SharePoint Tenant-Level Sharing Governance
+- **Strategic sequencing**: This is best treated as the bridge between the current governance engine and later framework-facing readiness work. It should land before substantial NIS2, BSI, ISO, COBIT, or similar mapping and auditor-pack expansion, and ideally before evidence or review surfaces hardcode control meaning locally.
+- **Roadmap fit**: Early-R2 foundation layer between the shipped governance engine and later compliance-readiness overlays.
+- **Priority**: high
+
+### CIS Baseline Library
+- **Type**: feature / library layer
+- **Source**: roadmap layering alignment 2026-04-22, baseline-library planning, future benchmark/template packaging
+- **Vehicle**: new standalone candidate
+- **Layer position**: **S2** — catalog-based template and library layer
+- **Problem**: Once TenantPilot has a framework-neutral canonical control catalog, it still needs a reusable library layer for widely recognized baseline packs such as CIS without turning CIS into the product's primary control ontology. Today that distinction does not exist explicitly in the candidate stack. Without a separate library-layer candidate, CIS guidance will tend to leak downward into the canonical catalog or upward into readiness views, blurring three different concerns: what a control is, what a reusable benchmark template recommends, and how a framework-specific readiness statement should be derived.
+- **Why it matters**: CIS is valuable to TenantPilot as a reusable template and benchmark library, not as the platform's canonical control object model. MSPs and operators need versioned, explainable baseline packs they can adopt, compare against, and use as a curated starting point. Keeping CIS in a library layer preserves the framework-neutral core, makes benchmark evolution manageable, and avoids letting one external source define the entire product architecture.
+- **Proposed direction**:
+  - Introduce versioned CIS-aligned template packs and baseline libraries that map onto canonical controls rather than redefining them
+  - Keep library-pack lifecycle explicit: import or activate, preview, diff, archive, and supersede without mutating the underlying control ontology
+  - Let one library item express expected-state guidance, applicability, severity or importance hints, and subject-level realization on top of the canonical control catalog
+  - Allow baseline profiles and later compare or reporting features to reference CIS library packs as curated starters or benchmark templates rather than a second control taxonomy
+  - Preserve room for future non-CIS libraries such as company standards, MSP reference packs, or vertical-specific benchmark packs built on the same catalog
+- **Scope boundaries**:
+  - **In scope**: CIS-aligned library-pack model, versioning and lifecycle, mapping to canonical controls and governed subjects, baseline-template consumption paths, and bounded operator-visible library metadata
+  - **Out of scope**: replacing the canonical control catalog, full framework readiness mapping, certification semantics, stakeholder-facing readiness reporting, or a generic pack marketplace
+- **Explicit non-goals**:
+  - Not a second control ontology beside the canonical catalog
+  - Not a readiness or evidence-mapping layer for NIS2, BSI, ISO, or COBIT
+  - Not a requirement that every canonical control must have a CIS template entry
+  - Not a forced replacement of operator-defined baseline profiles; library packs remain reusable starting points and references
+- **Acceptance points**:
+  - The platform can represent a CIS library version independently from canonical catalog versions and framework-readiness overlays
+  - A CIS library entry can point to canonical controls and governed-subject realizations without redefining the control itself
+  - Baseline workflows can consume CIS library packs as reusable templates or benchmark references without collapsing the product into a CIS-first model
+  - Library-pack evolution can show added, changed, retired, or superseded guidance without changing historical control meaning
+  - Future company-standard or MSP-specific libraries can reuse the same template-layer mechanics without inventing another control taxonomy
+- **Boundary with Canonical Control Catalog Foundation**: The canonical catalog defines what the control is. The CIS library defines one reusable benchmark or template expression built on top of that control.
+- **Boundary with Compliance Readiness & Executive Review Packs**: Compliance Readiness owns mapping, evidence assembly, and readiness statements for frameworks or stakeholder views. The CIS library owns reusable benchmark packs and templates, not readiness scoring or framework interpretation.
+- **Dependencies**: Canonical Control Catalog Foundation, Spec 202 (governed-subject vocabulary), baseline and drift foundations, and evidence alignment where benchmark reporting later consumes library references
+- **Related specs / candidates**: Canonical Control Catalog Foundation, Compliance Readiness & Executive Review Packs, Spec 202 (governance-subject-taxonomy), Spec 203 (baseline-compare-strategy), company standards / policy quality work
+- **Strategic sequencing**: Conceptually this is the S2 layer between the canonical control core and later framework-readiness overlays. It can ship after the control foundation once the catalog and governed-subject bindings are stable enough to host reusable benchmark templates.
+- **Roadmap fit**: S2 library layer for reusable benchmark and baseline packs.
+- **Priority**: medium-high
 
 ### Compliance Readiness & Executive Review Packs
 - **Type**: feature
 - **Source**: roadmap-to-spec coverage audit 2026-03-18, R2 theme completion, product positioning for German midmarket / MSP governance
 - **Vehicle note**: Tenant review and publication-readiness semantics should extend existing Spec 155 (`tenant-review-layer`), not become a separate candidate. This candidate remains about broader management/stakeholder-facing readiness outputs beyond the current review-layer spec.
+- **Layer position**: **S3** — mapping, evidence, and readiness layer
 - **Problem**: TenantPilot is building a strong evidence/data foundation (Spec 153, StoredReports, review pack export via Spec 109, findings, baselines), but there is no product-level capability that assembles this data into management-ready, customer-facing, or auditor-oriented readiness views. Enterprise customers, MSP account managers, and CISOs need structured governance outputs for recurring tenant reviews, audit preparation, and compliance conversations — not raw artifact collections or manual export assembly. The gap is not data availability; it is the absence of a dedicated readiness presentation and packaging layer that turns existing governance evidence into actionable, consumable deliverables.
-- **Why it matters**: This is a core product differentiator and revenue-relevant capability for the MSP and German midmarket audience. Without it, TenantPilot remains an operator tool — powerful but invisible to the stakeholders who sign off on governance, approve budgets, and evaluate vendor value. Structured readiness outputs (lightweight BSI/NIS2/CIS-oriented views, executive summaries, customer review packs) make TenantPilot sellable as a governance review platform, not just a backup and configuration tool. This directly strengthens the MSP sales story for quarterly reviews, security health checks, and audit preparation.

This directly strengthens the MSP sales story for quarterly reviews, security health checks, and audit preparation.
 - **Proposed direction**:
   - A dedicated readiness/review presentation layer that consumes evidence domain artifacts, findings summaries, baseline/drift posture, permission posture signals, and operational health data
-  - Management-ready output surfaces: executive summary views, customer-facing review dashboards, structured compliance readiness pages oriented toward frameworks such as BSI Grundschutz, NIS2, and CIS — in a lightweight, non-certification sense (governance evidence, not formal compliance claims)
+  - Management-ready output surfaces: executive summary views, customer-facing review dashboards, and structured readiness pages oriented toward frameworks such as BSI Grundschutz and NIS2 — in a lightweight, non-certification sense (governance evidence, not formal compliance claims)
   - Exportable review packs that combine multiple evidence dimensions into a single coherent deliverable (PDF or structured export) for external stakeholders
   - Tenant-scoped and workspace-scoped views — individual tenant reviews as well as portfolio-level readiness summaries
   - Clear separation from the Evidence Domain Foundation: evidence foundation owns curation, completeness tracking, and artifact storage; compliance readiness owns presentation, assembly, and stakeholder-facing output
+  - Keep ISO and COBIT in governance-, assurance-, ISMS-, and readiness-oriented overlays rather than introducing them as a separate technical control library
   - Readiness views should be composable: an operator selects which dimensions to include in a review pack (e.g. baseline posture + findings summary + permission evidence + operational health) rather than a monolithic fixed report
 - **Explicit non-goals**: Not a formal certification engine — TenantPilot does not certify compliance or issue attestations. Not a legal or compliance advice system. Not a replacement for the Evidence Domain Foundation (which owns the data layer). Not a generic BI dashboard or data warehouse initiative. Not a PDF-only export task — the primary value is the structured readiness view, with export as a secondary delivery mechanism. Not a reimplementation of review pack export (Spec 109 handles CSV/ZIP). Not a customer-facing analytics suite.
 - **Boundary with Evidence Domain Foundation**: Evidence Domain Foundation = curation, completeness tracking, artifact storage, immutable snapshots. Compliance Readiness = presentation, assembly, framework-oriented views, stakeholder-facing outputs. Evidence Foundation is a prerequisite; Compliance Readiness is a consumer.
-- **Dependencies**: Evidence Domain Foundation (data layer), review pack export (Spec 109), findings workflow (Spec 111), baseline/drift engine (Specs 116–119), permission posture (Specs 104/105), audit log foundation (Spec 134)
+- **Boundary with Canonical Control Catalog Foundation**: Canonical Control Catalog Foundation = framework-neutral control core, detectability semantics, and control-to-subject or evidence alignment. Compliance Readiness = framework-aware presentation, rollup, and stakeholder-facing output built on top of that shared control layer.
+- **Boundary with CIS Baseline Library**: The CIS library owns reusable template packs and benchmark baselines. Compliance Readiness owns NIS2, BSI, and later governance-assurance overlays that map evidence and control coverage into readiness statements.
+- **Dependencies**: Canonical Control Catalog Foundation, Evidence Domain Foundation (data layer), review pack export (Spec 109), findings workflow (Spec 111), baseline/drift engine (Specs 116–119), permission posture (Specs 104/105), audit log foundation (Spec 134)
+- **Strategic sequencing**: This is the S3 layer. It should consume the canonical control core and evidence model, and it should remain separate from the CIS template-library layer so benchmark packs and readiness mappings do not collapse into the same object family.
 - **Priority**: medium (high strategic value, but depends on evidence foundation maturity)

-### Tenant App Status False-Truth Removal
-- **Type**: hardening
-- **Source**: legacy / orphaned truth audit 2026-03-16
-- **Classification**: quick removal
-- **Problem**: `Tenant.app_status` is displayed in tenant UI as current operational truth even though production code no longer writes it. Operators can see a frozen "OK" or other stale badge that does not reflect the real provider connection state.
-- **Why it matters**: This is misleading operator-facing truth, not just dead schema. It creates false confidence on a tier-1 admin surface.
-- **Target model**: `Tenant`
-- **Canonical source of truth**: `ProviderConnection.consent_status` and `ProviderConnection.verification_status`
-- **Must stop being read**: `Tenant.app_status` in `TenantResource` table columns, infolist/details, filters, and badge-domain mapping.
-- **Can be removed immediately**:
-  - TenantResource reads of `app_status`
-  - tenant app-status badge domain / badge mapping usage
-  - factory defaults that seed `app_status`
-- **Remove only after cutover**:
-  - the `tenants.app_status` column itself, once all UI/report/export reads are confirmed gone
-- **Migration / backfill**: No backfill. One cleanup migration to drop `app_status`. `app_notes` may be dropped in the same migration only if it does not broaden the spec beyond tenant stale app fields.
-- **UI / resource / policy / test impact**:
-  - UI/resources: remove misleading badge and filter from tenant surfaces
-  - Policy: none
-  - Tests: update `TenantFactory`, remove assertions that treat `app_status` as live truth
-- **Scope boundaries**:
-  - In scope: remove stale tenant app-status reads and schema field
-  - Out of scope: provider connection UX redesign, credential migration, broader tenant health redesign
-- **Dependencies**: None required if the immediate operator-facing action is removal rather than replacement with a new tenant-level derived badge.
-- **Risks**: Low rollout risk. Main risk is short-term operator confusion about where to view connection health after removal.
-- **Why it should be its own spec**: This is the cleanest high-severity operator-trust fix in the repo. It is bounded, low-coupling, and should not wait for the larger provider cutover work.

+> 2. **Onboarding State Fallback Retirement**
+> 3. **Canonical Operation Type Source of Truth**
+>
+> The first two candidates remove dead or weakly justified compatibility residue. The third resolves the remaining core semantic conflict that still spans persistence, registries, resources, specs, and tests.
+
+### Dead Transitional Residue Cleanup
+- **Type**: hardening / cleanup
+- **Source**: strict read-only legacy / compatibility audit 2026-04-22; orphaned-truth residue review
+- **Absorbs / broadens**: the earlier `Tenant App Status False-Truth Removal` slice plus adjacent dead-symbol cleanup
+- **Problem**: The repo still contains smaller transitional residues that no longer carry active product semantics but still survive in code, badges, factories, fixtures, and tests. Confirmed examples include unused deprecated `BaselineProfile::STATUS_*` constants and orphaned tenant app-status residue that now mainly persists as badge, factory, fixture, and test conservat.
+- **Why it matters**: Each residue is small, but together they blur the real domain language, preserve dead semantics in tests, and make later cleanup harder because it is no longer obvious which symbols are still authoritative.
+- **Goal**: Remove dead transitional residue that no longer drives runtime, UI, filter, cast, or API behavior, and clean up associated tests, fixtures, and factories in the same change.
+- **In scope**:
+  - remove unused deprecated `BaselineProfile::STATUS_*` constants
+  - remove orphaned tenant app-status badge, factory, fixture, and test residue
+  - verify that no hidden runtime, UI, filter, cast, or API dependency still exists before removal
+  - document the remaining active domain language after cleanup
+- **Out of scope**: operation-type dual semantics, onboarding state fallbacks, provider identity or migration review, Baseline Scope V2, and spec-backed legacy redirect paths.
+- **Key requirements**:
+  - dead deprecated constants must be removed when no productive reference remains
+  - orphaned badge, status, factory, and fixture residue must not survive as silent compatibility lore
+  - cleanup must include tests and fixtures in the same change
+  - removal must prove there is no hidden runtime, UI, filter, cast, or API dependency
+  - the remaining canonical domain language must be clearer after cleanup
+- **Acceptance characteristics**:
+  - deprecated `BaselineProfile::STATUS_*` constants are gone
+  - tenant app-status residue is removed or reduced to explicitly justified boundary-only remnants
+  - no productive references to removed symbols remain
+  - tests no longer conserve dead semantics
+- **Boundary with Provider Connection Legacy Cleanup**: provider connection cleanup owns still-legitimate or spec-bound provider transitional paths. This candidate only removes dead residue with no active product role.
+- **Strategic sequencing**: first step of the repository cleanup strand.
+- **Priority**: high
+
+### Onboarding State Fallback Retirement
+- **Type**: hardening / cleanup
+- **Source**: strict read-only legacy / compatibility audit 2026-04-22; onboarding state-key audit
+- **Problem**: Onboarding still carries mixed old and new state keys and service-level fallback reads between older fields and newer canonical fields. Some keys still have distinct roles, such as mutable selector state versus trusted persisted state, but others now appear to survive only as historical fallback.
+- **Why it matters**: In a pre-production repo, silent fallback between state classes keeps semantic boundaries fuzzy and makes future trusted-state hardening harder. New work can accidentally bind to retired keys because the service layer still tolerates them.
+- **Goal**: Retire pure onboarding fallback keys and make the remaining split between selector state and trusted persisted state explicit.
+- **In scope**:
+  - audit and retire pure fallback keys such as `verification_run_id` and `bootstrap_run_ids` if no current contract still needs them
+  - remove corresponding fallback reads in onboarding services
+  - align contracts and tests to the remaining active key language
+  - document which onboarding keys remain active and why
+- **Out of scope**: removing `selected_provider_connection_id` while it still has an active contract role, provider identity or migration review, and generic session or trusted-state architecture redesign.
+- **Key requirements**:
+  - onboarding keys with no active contractual role must be removed when they survive only as fallback
+  - selector state and trusted state must be semantically separated
+  - silent fallback between semantically different state classes must not persist without an explicit current contract
+  - specs, contracts, and service read behavior must converge on the same remaining keys
+  - tests must stop conserving retired fallback fields
+- **Risks / open questions**:
+  - `selected_provider_connection_id` still appears in current contracts and should not be treated as dead residue by default
+  - some onboarding keys may require contract cleanup before code cleanup can be completed cleanly
+- **Strategic sequencing**: second step of the repository cleanup strand, after `Dead Transitional Residue Cleanup` and before `Canonical Operation Type Source of Truth`.

+# Data Model: Assignment Hygiene & Stale Work Detection
+
+## Overview
+
+This feature introduces no new persisted business entity. Existing finding truth, audit logs, tenant memberships, and user lifecycle truth remain canonical. The new work is one bounded derived hygiene layer over those existing records.
+
+## Existing Persistent Entities
+
+### Finding
+
+**Purpose**: Canonical tenant-scoped findings workflow truth for ownership, lifecycle, and timing.
+
+**Key fields used by this feature**:
+
+- `id`
+- `workspace_id`
+- `tenant_id`
+- `status`
+- `owner_user_id`
+- `assignee_user_id`
+- `due_at`
+- `in_progress_at`
+- `reopened_at`
+- `resolved_at`
+- `closed_at`
+- `last_seen_at`
+- `times_seen`
+
+**Relationships**:
+
+- belongs to one workspace
+- belongs to one tenant
+- may reference one current owner user
+- may reference one current assignee user
+
+**Rules relevant to hygiene**:
+
+- Only non-terminal findings participate in hygiene evaluation.
+- Owner-only findings are not hygiene issues by themselves.
+- Unassigned intake findings are not hygiene issues by themselves.
+- `last_seen_at` remains observation truth and must not reset the stale operator-work window.
+
+### AuditLog
+
+**Purpose**: Existing audit truth for workflow actions and responsibility changes.
+
+**Key fields used by this feature**:
+
+- `id`
+- `workspace_id`
+- `tenant_id`
+- `auditable_type`
+- `auditable_id`
+- `action`
+- `created_at`
+
+**Rules relevant to hygiene**:
+
+- Existing finding workflow audit actions provide one source of workflow-activity timestamps.
+- No new audit action id is required for this feature because the report is read-only.
+
+### User
+
+**Purpose**: Canonical operator identity record.
+
+**Key fields used by this feature**:
+
+- `id`
+- `deleted_at`
+
+**Rules relevant to hygiene**:
+
+- Soft-deleted users are treated as unavailable for current assignment execution.
+- The feature does not add a separate availability state.
+
+### Tenant Membership / Tenant Entitlement Truth
+
+**Purpose**: Current authorization truth for whether an assignee can still work inside the tenant.
+
+**Key inputs used by this feature**:
+
+- membership existence for the tenant
+- current tenant visibility
+- current findings-view capability in the referenced tenant
+
+**Rules relevant to hygiene**:
+
+- Broken assignment is derived from current workability, not historical assignment legitimacy.
+- Hidden tenants remain excluded from rows, counts, and filters.
+
+## Derived Models
+
+### FindingHygieneIssue
+
+**Purpose**: Canonical derived issue envelope used by both the report and the overview signal.
+
+**Fields**:
+
+- `finding_id`
+- `workspace_id`
+- `tenant_id`
+- `tenant_name`
+- `finding_summary`
+- `status`
+- `owner_user_id`
+- `owner_name`
+- `assignee_user_id`
+- `assignee_name`
+- `reasons`: list of hygiene reasons
+- `last_workflow_activity_at`
+- `due_at`
+- `is_overdue`
+
+**Validation rules**:
+
+- The finding must be non-terminal.
+- `finding_summary`, `owner_name`, and `assignee_name` are display-ready values resolved from the current finding and loaded user relationships; they remain derived, not persisted.
+- `reasons` contains one or more of the allowed hygiene reasons.
+- `last_workflow_activity_at` is derived from workflow anchors only and must not come from observation freshness.
+- One finding produces one issue row even when multiple reasons apply.
+
+### HygieneReason
+
+**Purpose**: Bounded derived reason vocabulary for this feature.
+
+**Allowed values**:
+
+- `broken_assignment`
+- `stale_in_progress`
+
+**Rules**:
+
+- Reasons are derived labels, not persisted finding status.
+- Reasons exist because they change operator routing and filter behavior on the hygiene surface.
+
+### FindingsHygieneOverviewSignal
+
+**Purpose**: Workspace overview summary projection for fast discovery.
+
+**Fields**:
+
+- `headline`
+- `description`
+- `unique_issue_count`
+- `broken_assignment_count`
+- `stale_in_progress_count`
+- `is_calm`
+- `cta_label`
+- `cta_url`
+
+**Rules**:
+
+- Counts are based on unique visible finding issues, not duplicated reason rows.
+- `description` is a short operator-facing summary derived from broken-assignment and stale-in-progress counts; no separate severity ordering is introduced.
+- When `unique_issue_count = 0`, the signal remains visible in a calm state with zero issues, calm descriptive copy, and the canonical CTA into the report.
+- The signal uses the same source query and tenant visibility truth as the canonical report.
+
+## Classification Matrix
+
+| Reason | Trigger | Required finding state | Required visibility truth | Exclusions |
+|--------|---------|------------------------|---------------------------|------------|
+| `broken_assignment` | Assignee can no longer act | non-terminal, `assignee_user_id` present | current user may see the finding and the assigned user is either soft-deleted or no longer tenant-entitled | owner-only, unassigned, hidden tenant |
+| `stale_in_progress` | No meaningful workflow movement for 7 days | `status = in_progress` and non-terminal | current user may see the finding | merely overdue, recently reassigned, recently reopened, or recently moved into progress |
+
+## Workflow Activity Anchor Rules
+
+- `in_progress_at` is the baseline activity anchor for work that actually started.
+- `reopened_at` can reset the stale window when the finding re-enters active lifecycle.
+- Existing workflow audit rows for `finding.assigned`, `finding.in_progress`, and `finding.reopened` can supersede the baseline anchor when they are newer.
+- `last_seen_at` and `times_seen` remain observation truth only and must not reset the stale-work window.
+
+## Persistence Boundaries
+
+- No new table, enum-backed persistence, or report snapshot is introduced.
+- The hygiene report and overview signal are recalculated from current truth at read time.
+- Repair continues through the existing finding detail mutation path and its current audit behavior.

+# Implementation Plan: Assignment Hygiene & Stale Work Detection
+
+**Branch**: `225-assignment-hygiene` | **Date**: 2026-04-22 | **Spec**: `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/225-assignment-hygiene/spec.md`
+**Input**: Feature specification from `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/225-assignment-hygiene/spec.md`
+
+**Note**: This plan keeps the work inside the existing findings workflow, canonical admin-plane findings pages, workspace overview builder, and current tenant finding detail repair actions. The intended implementation adds one new read-first findings hygiene page, one small overview signal, and one narrow derived-query service. It does not add a new table, a new workflow state, a notification channel, an automation engine, or a second repair surface.
+
+## Summary
+
+Introduce a canonical `/admin/findings/hygiene` report plus a matching workspace overview signal that surface unhealthy findings workflow items, including broken assignments and stale in-progress work. Back both surfaces with one narrow `FindingAssignmentHygieneService` that derives `broken assignment` and `stale in progress` from existing `Finding` lifecycle fields, current tenant entitlement, user soft-delete truth, and existing finding workflow audit timestamps. Reuse the current tenant finding detail route for repair, preserve `My Findings` and intake as the healthy-work and unassigned-work surfaces, and keep the new hygiene slice strictly read-first.
+
+## Technical Context
+
+**Language/Version**: PHP 8.4.15, Laravel 12, Filament v5, Livewire v4, Blade  
+**Primary Dependencies**: `Finding`, `FindingResource`, `MyFindingsInbox`, `FindingsIntakeQueue`, `WorkspaceOverviewBuilder`, `EnsureFilamentTenantSelected`, `FindingWorkflowService`, `AuditLog`, `TenantMembership`, Filament page and table primitives  
+**Storage**: PostgreSQL via existing `findings`, `audit_logs`, `tenant_memberships`, and `users`; no schema changes planned  
+**Testing**: Pest v4 feature tests with Filament/Livewire assertions  
+**Validation Lanes**: fast-feedback, confidence
+**Target Platform**: Dockerized Laravel web application via Sail locally and Linux containers in deployment  
+**Project Type**: Laravel monolith inside the `wt-plattform` monorepo  
+**Performance Goals**: Keep report and overview queries scoped to visible tenants, avoid N+1 owner or assignee resolution, and keep summary counts cheap enough for the existing `/admin` overview render path  
+**Constraints**: No new persistence, no hidden-tenant leakage, no automatic reassignment, no new findings lifecycle state, no new assets, and no inline repair mutation on the hygiene report  
+**Scale/Scope**: One new canonical admin-plane report, one new overview signal, one narrow findings service, one Blade view, one middleware route allow-list update, and three focused feature suites
+
+## UI / Surface Guardrail Plan
+
+- **Guardrail scope**: changed surfaces
+- **Native vs custom classification summary**: native Filament page, table, empty-state, and workspace summary primitives only
+- **Shared-family relevance**: findings workflow family (`My Findings`, intake, finding detail) and workspace overview signal family
+- **State layers in scope**: shell, page, detail, URL-query
+- **Handling modes by drift class or surface**: review-mandatory
+- **Repository-signal treatment**: review-mandatory
+- **Special surface test profiles**: standard-native-filament, global-context-shell
+- **Required tests or manual smoke**: functional-core, state-contract
+- **Exception path and spread control**: none; the feature adds one bounded findings page and one overview signal rather than a new shared UI family
+- **Active feature PR close-out entry**: Guardrail
+
+## Constitution Check
+
+*GATE: Passed before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Pre-Research | Post-Design | Notes |
+|-----------|--------------|-------------|-------|
+| Inventory-first / snapshots-second | PASS | PASS | Hygiene remains derived from live finding workflow truth, not from snapshots or exports |
+| Read/write separation | PASS | PASS | The report and overview signal are read-only; repair stays on the existing finding detail actions and audit path |
+| Graph contract path | PASS | PASS | No Microsoft Graph call path or contract-registry change is introduced |
+| Deterministic capabilities / RBAC-UX | PASS | PASS | Admin-plane report rows and counts remain tenant-safe, non-members stay `404`, and current finding-view capability stays authoritative for disclosure |
+| Workspace / tenant isolation | PASS | PASS | `/admin/findings/hygiene` is tenantless by URL but every row, count, and filter remains tenant-entitlement checked |
+| Run observability / Ops-UX | PASS | PASS | No new `OperationRun`, queued workflow, or notification family is introduced |
+| Proportionality / no premature abstraction | PASS | PASS | One narrow service is justified because both the report and overview signal need the same derived issue truth and counting rules |
+| Persisted truth / few layers | PASS | PASS | No table, materialized hygiene state, or UI-only lifecycle is introduced |
+| Behavioral state discipline | PASS | PASS | `broken assignment` and `stale in progress` remain derived hygiene reasons, not new persisted finding statuses |
+| Filament-native UI (UI-FIL-001) | PASS | PASS | The feature uses a native Filament page, native table filters, native empty-state affordances, and existing workspace-summary primitives |
+| Decision-first / action-surface contract | PASS | PASS | The report is the one primary repair surface, the overview signal is a secondary drill-in, and repair still happens on the existing finding detail |
+| Test governance (TEST-GOV-001) | PASS | PASS | Proof stays in focused feature suites for hygiene classification, visibility, overview counts, and drilldown safety |
+| Filament v5 / Livewire v4 compliance | PASS | PASS | The feature adds a Filament v5 page and stays inside Livewire v4-compatible patterns |
+| Provider registration / global search / assets | PASS | PASS | Panel providers remain in `apps/platform/bootstrap/providers.php`; no new globally searchable resource or asset family is added |
+
+## Test Governance Check
+
+- **Test purpose / classification by changed surface**: `Feature` for the hygiene report, derived classification, overview signal consistency, and tenant-safe disclosure behavior
+- **Affected validation lanes**: `fast-feedback`, `confidence`
+- **Why this lane mix is the narrowest sufficient proof**: The primary risks are integrated operator outcomes: which findings appear, why they appear, whether hidden tenants leak into counts, whether the overview matches the canonical report, and whether row drilldown preserves the existing authorization contract. Focused feature tests prove that without adding browser or heavy-governance breadth.
+- **Narrowest proving command(s)**:
+  - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`
+  - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+- **Fixture / helper / factory / seed / context cost risks**: Moderate. Tests need mixed visible versus hidden tenant memberships, soft-deleted or entitlement-lost assignees, in-progress timestamps, existing finding workflow audit rows, and active tenant prefilter state.
+- **Expensive defaults or shared helper growth introduced?**: no; any hygiene-specific fixtures should stay local to the new tests and reuse existing findings workflow helpers
+- **Heavy-family additions, promotions, or visibility changes**: none
+- **Surface-class relief / special coverage rule**: `standard-native-filament` for the canonical report and `global-context-shell` for the workspace overview signal plus tenantless route safety
+- **Closing validation and reviewer handoff**: Reviewers should rely on the exact commands above and verify that healthy assigned work stays out of the hygiene report, ordinary intake backlog stays out, one finding with two reasons counts once, the active tenant prefilter can be cleared back to all visible tenants, and the overview signal uses the same unique issue truth as the report.
+- **Budget / baseline / trend follow-up**: none
+- **Review-stop questions**: Did the implementation introduce a persisted hygiene flag or table? Did stale detection rely on observation fields such as `last_seen_at` or generic `updated_at` instead of workflow activity? Did any route or count leak hidden-tenant findings? Did the report gain inline repair actions or other mutation drift?
+- **Escalation path**: document-in-feature unless a new persistence model, automation engine, or broad availability framework is proposed, in which case split or follow up with a dedicated spec
+- **Active feature PR close-out entry**: Guardrail
+- **Why no dedicated follow-up spec is needed**: This feature remains bounded to one report, one signal, and one narrow derived-query seam over current findings workflow truth

+
+**Structure Decision**: Standard Laravel monolith. The feature stays inside the existing findings page family, workspace overview builder, and findings workflow service seams. No new base directory, panel, or persisted model is required.
+
+## Complexity Tracking
+
+| Violation | Why Needed | Simpler Alternative Rejected Because |
+|-----------|------------|-------------------------------------|
+| none | — | — |
+
+## Proportionality Review
+
+- **Current operator problem**: Assigned findings can silently become unworkable or stale after assignment, and no existing cross-tenant surface exposes those failures in one repair context.
+- **Existing structure is insufficient because**: `My Findings` only answers healthy assigned work for the current user, intake only answers unassigned backlog, and the overview today has no workflow-hygiene signal. Duplicating derived issue logic in both a new page and the overview would drift quickly.
+- **Narrowest correct implementation**: Add one new report page and one summary signal backed by one narrow findings hygiene service that centralizes classification and count rules while keeping repair on the existing finding detail page.
+- **Ownership cost created**: One small service, one page, one Blade view, one overview builder extension, one middleware allow-list update, and three focused feature suites.
+- **Alternative intentionally rejected**: A generic workflow health engine or a persisted hygiene table. Both add more machinery than current release truth needs because only the findings workflow consumes this derived issue model today.
+- **Release truth**: Current-release truth. The feature repairs an active workflow trust gap now rather than preparing a later autonomous work-routing platform.
+
+## Phase 0 Research
+
+Research outcomes are captured in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/225-assignment-hygiene/research.md`.
+
+Key decisions:
+
+- Add a dedicated canonical report at `/admin/findings/hygiene` instead of stretching `My Findings` or intake beyond their current decision role.
+- Reuse the existing workspace overview signal pattern in `WorkspaceOverviewBuilder` instead of creating a new widget family.
+- Add one narrow `FindingAssignmentHygieneService` because both the report and overview signal need the same classification and counting truth.
+- Derive broken assignment from current tenant entitlement plus existing user soft-delete truth rather than introducing a new availability model.
+- Derive stale work from finding workflow timestamps plus existing finding workflow audit events, not from observation fields such as `last_seen_at` or generic `updated_at`.
+- Keep repair on the existing tenant finding detail route and current assignment actions; the hygiene report stays read-first.
+
+## Phase 1 Design
+
+Design artifacts are created under `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/225-assignment-hygiene/`:
+
+- `research.md`: report-shape, classification-source, and reuse decisions
+- `data-model.md`: existing entities plus the derived hygiene issue and overview-signal models
+- `contracts/assignment-hygiene.logical.openapi.yaml`: internal logical contract for the canonical report, overview signal, and finding drilldown
+- `quickstart.md`: focused validation workflow for implementation and review
+
+Design decisions:
+
+- No schema migration is required; hygiene remains derived from current `Finding`, `AuditLog`, user, and membership truth.
+- The canonical new seam is one narrow `FindingAssignmentHygieneService`, not a broad workflow-health framework.
+- Stale detection uses workflow activity anchors, not observation freshness fields.
+- The canonical repair surface remains the existing tenant finding detail route.
+- Existing `My Findings` and intake inclusion rules remain unchanged.
+
+## Phase 1 Agent Context Update
+
+Run:
+
+- `.specify/scripts/bash/update-agent-context.sh copilot`
+
+## Constitution Check — Post-Design Re-evaluation
+
+- PASS — the design stays inside current findings, audit, workspace overview, and Filament page seams with no new persistence, no Graph work, no new capability family, and no new assets.
+- PASS — Livewire v4.0+ and Filament v5 constraints remain satisfied, panel provider registration stays in `apps/platform/bootstrap/providers.php`, no globally searchable resource behavior changes, and no destructive action path is added on the new report.
+
+## Implementation Strategy
+
+### Phase A — Add the canonical hygiene report shell and route treatment
+
+**Goal**: Create the new admin-plane report without disturbing the current findings page family.
+
+| Step | File | Change |
+|------|------|--------|
+| A.1 | `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php` | Add the new Filament page with slug `findings/hygiene`, canonical row drilldown into `FindingResource`, fixed reason filters, active-tenant prefilter behavior, and read-first table semantics |
+| A.2 | `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php` | Add the page shell using the same findings page family layout patterns as `MyFindingsInbox` and `FindingsIntakeQueue` |
+| A.3 | `apps/platform/app/Support/Middleware/EnsureFilamentTenantSelected.php` | Extend the tenant-selection bypass and workspace-scoped navigation handling so `/admin/findings/hygiene` behaves like the existing tenantless canonical findings pages |
+
+### Phase B — Add one narrow derived hygiene service over existing findings truth
+
+**Goal**: Centralize hygiene classification and count truth for both the report and the overview signal.
+
+| Step | File | Change |
+|------|------|--------|
+| B.1 | `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php` | Add a focused service that scopes findings to visible tenants, derives hygiene reasons, returns the canonical report query, and computes unique summary counts |
+| B.2 | `apps/platform/app/Models/Finding.php` | Reuse existing open-status and responsibility fields; add only narrow query helpers if they materially simplify the hygiene service without introducing a new semantic layer |
+| B.3 | `apps/platform/app/Models/AuditLog.php` or existing audit query seam | Reuse existing finding workflow audit rows as one stale-activity input rather than persisting a new timestamp |
+
+### Phase C — Implement broken-assignment and stale-work classification on real existing truth
+
+**Goal**: Make the derived reasons honest without inventing new persistence or generic availability models.
+
+| Step | File | Change |

+## Implementation Close-out
+
+- **Status**: Implemented and verified on 2026-04-22.
+- **Implemented scope**:
+  - Added the canonical admin-plane report at `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php` with a matching Blade view, fixed reason views, row-click drilldown only, and tenant-prefilter recovery.
+  - Added `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php` as the single derived-query and count truth for report rows plus workspace overview signal counts.
+  - Extended `apps/platform/app/Services/Findings/FindingWorkflowService.php` to expose shared meaningful workflow activity anchors.
+  - Wired `/admin/findings/hygiene` into `apps/platform/app/Providers/Filament/AdminPanelProvider.php`, `apps/platform/app/Support/Middleware/EnsureFilamentTenantSelected.php`, `apps/platform/app/Support/Workspaces/WorkspaceOverviewBuilder.php`, and `apps/platform/resources/views/filament/pages/workspace-overview.blade.php`.
+  - Added focused Pest coverage in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`, `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`, and `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`.
+- **Proof commands run**:
+  - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+  - `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
+  - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+- **Guardrail outcome**:
+  - Livewire v4.0+ / Filament v5 compliance remains intact.
+  - Provider registration location remains unchanged in `bootstrap/providers.php`.
+  - No global-search resource behavior changed.
+  - No destructive action was added on the new report.
+  - No new asset family was introduced, so existing deployment behavior stays sufficient.

+# Quickstart: Assignment Hygiene & Stale Work Detection
+
+## Prerequisites
+
+1. Start the local platform stack.
+
+   ```bash
+   cd apps/platform && ./vendor/bin/sail up -d
+   ```
+
+2. Work with a workspace that has at least two visible tenants, several open findings, and at least two tenant users.
+
+3. Ensure at least one scenario can represent each hygiene state:
+   - a finding assigned to a user who later loses tenant access or is soft-deleted
+   - a finding left `in_progress` beyond the stale window without later workflow movement
+
+4. Remember that `/admin/findings/hygiene` is a workspace-context canonical page, so tenant selection should not be required to open it.
+
+## Automated Validation
+
+Run formatting and the narrowest proving suites for this feature:
+
+```bash
+cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent
+cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php
+cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php
+```
+
+## Manual Validation Flow
+
+### 1. Confirm the canonical report opens in workspace context
+
+1. Open `/admin/findings/hygiene` without selecting an active tenant.
+2. Confirm the page opens as a workspace-context findings surface.
+3. Confirm row drilldown still lands on the existing tenant finding detail page.
+
+### 2. Validate broken-assignment detection
+
+1. Start with an open assigned finding in a visible tenant.
+2. Remove the assignee's tenant membership or soft-delete the assigned user.
+3. Reload the hygiene report.
+4. Confirm the finding appears once with `Broken assignment` and still shows owner context.
+
+### 3. Validate stale in-progress detection
+
+1. Start with an open finding moved to `In progress` more than seven days ago.
+2. Ensure no later assignment or reopen workflow activity exists for that finding.
+3. Reload the hygiene report.
+4. Confirm the finding appears with `Stale in progress`.
+5. Move a comparable finding to `In progress` recently or reassign it recently and confirm it does not appear as stale.
+6. Reopen a comparable finding after it would otherwise qualify as stale and confirm it no longer appears as stale until seven days pass from the reopen activity.
+
+### 4. Validate multi-reason and unique-count behavior
+
+1. Prepare one finding that is both assigned to an unworkable assignee and stale in progress.
+2. Reload the report and workspace overview.
+3. Confirm:
+   - the report shows one row with both reasons visible
+   - the workspace overview counts one unique hygiene issue, not two separate rows
+
+### 5. Validate overview discoverability
+
+1. Open `/admin` with visible hygiene issues present.
+2. Confirm the findings hygiene signal appears with one CTA into the report.
+3. Confirm the signal description is a short summary derived from broken-assignment and stale-in-progress counts rather than an undefined severity ordering.
+4. Open the CTA and verify the canonical report reflects the same visible issue truth.
+5. Repeat the check with no visible hygiene issues and confirm the same signal remains visible in a calm state with zero issues and the canonical CTA into the report.
+
+### 6. Validate tenant-prefilter and hidden-tenant safety
+
+1. Open the report with an active tenant selected.
+2. Confirm the report is prefiltered to that tenant while keeping the fixed hygiene scope.
+3. If the prefilter hides issues that exist in other visible tenants, confirm the empty state explains that boundary and offers exactly one `Clear tenant filter` CTA.
+4. Confirm hidden-tenant findings never appear in rows, counts, filter values, or empty-state hints.
+
+## Reviewer Notes
+
+- The feature is Livewire v4.0+ compatible and stays on existing Filament v5 primitives.
+- Provider registration remains unchanged in `apps/platform/bootstrap/providers.php`.
+- No globally searchable resource behavior changes in this feature.
+- No new destructive action is introduced on the hygiene report, so no new confirmation flow is required there.
+- Asset strategy is unchanged: no new panel or shared assets, and the existing deploy `filament:assets` step remains sufficient.

+# Research: Assignment Hygiene & Stale Work Detection
+
+## Decision 1: Add a dedicated hygiene report instead of stretching `My Findings` or intake
+
+**Decision**: Create a new canonical admin-plane page at `/admin/findings/hygiene` rather than adding one more fixed view to `My Findings` or the intake queue.
+
+**Rationale**: `My Findings` already answers the personal execution question and intake already answers the shared unassigned-backlog question. Hygiene is a third operator question: which assigned or in-progress findings are no longer in a healthy workflow path across visible tenants. Mixing that into either existing surface would blur their current decision role.
+
+**Alternatives considered**:
+
+- Add a `Needs repair` filter to `My Findings`. Rejected because broken assignments often no longer belong to the current operator, so the personal queue would still miss the cross-tenant repair problem.
+- Add another fixed mode to intake. Rejected because intake is explicitly about pre-assignment backlog, not unhealthy assigned work.
+
+## Decision 2: Reuse the existing workspace overview signal pattern
+
+**Decision**: Extend `WorkspaceOverviewBuilder` with one findings hygiene signal rather than creating a new dashboard widget family.
+
+**Rationale**: The repository already exposes `my_findings_signal` from `WorkspaceOverviewBuilder`, and `/admin` is already the accepted discoverability surface for workspace-wide findings follow-up. A second signal in the same builder keeps counts, phrasing, and drill-in behavior in one place.
+
+**Alternatives considered**:
+
+- Build a dedicated Livewire widget. Rejected because the current overview already has a signal builder pattern and this feature does not need a new widget framework.
+- Make the report discoverable only through navigation. Rejected because the spec explicitly wants a small overview signal that exposes hidden workflow decay before operators start browsing deeper pages.
+
+## Decision 3: Use one narrow `FindingAssignmentHygieneService`
+
+**Decision**: Add one focused service that owns hygiene classification, filtering, and unique-count aggregation for both the report and the overview signal.
+
+**Rationale**: This feature has two real concrete consumers of the same derived truth: the canonical report and the overview signal. Duplicating issue classification in both places would drift quickly. A narrow service is the smallest justified shared seam and does not require a generic workflow-health framework.
+
+**Alternatives considered**:
+
+- Duplicate the queries in the report page and `WorkspaceOverviewBuilder`. Rejected because tenant-visible scope, multi-reason counting, and stale-work anchoring would diverge under maintenance.
+- Introduce a broader workflow-health engine. Rejected because findings are the only real consumer today.
+
+## Decision 4: Keep broken-assignment truth bounded to current entitlement and existing user lifecycle
+
+**Decision**: In v1, classify `broken assignment` from two existing truths only: the assignee no longer has current tenant entitlement, or the assignee user record is soft-deleted. Do not introduce absence, capacity, or shift scheduling models.
+
+**Rationale**: The repository already enforces tenant membership as the true work boundary, and `User` already uses `SoftDeletes`. Those are real current truths. Anything broader would require new product modeling and would violate the spec's narrow scope.
+
+**Alternatives considered**:
+
+- Add an explicit operator-availability state or calendar. Rejected because it introduces a new workflow domain and new persistence unrelated to the current slice.
+- Treat every owner-only finding as broken. Rejected because owner-only accountability is already a valid state under Spec 219 and belongs outside this hygiene slice unless assignment is actually broken.
+
+## Decision 5: Derive stale work from workflow activity, not observation freshness
+
+**Decision**: Derive `stale in progress` from workflow activity anchors such as `in_progress_at`, `reopened_at`, and the latest existing finding workflow audit event (`finding.assigned`, `finding.in_progress`, `finding.reopened`) rather than from `last_seen_at` or generic `updated_at`.
+
+**Rationale**: Observation pipelines update `last_seen_at` and may touch the record during recurring detection, which would falsely calm truly stale operator work. The stale question here is whether workflow moved, not whether the problem was re-observed by the system.
+
+**Alternatives considered**:
+
+- Use `last_seen_at`. Rejected because recurring detection would reset the stale window even when no operator work happened.
+- Use `updated_at`. Rejected because model updates are broader than workflow activity and would make stale classification depend on incidental writes.
+- Add a new `last_workflow_activity_at` column. Rejected because the spec explicitly prefers derivation over new persistence.
+
+## Decision 6: Keep repair on the existing finding detail surface
+
+**Decision**: The hygiene report remains read-first and uses row click to drill into the existing tenant finding detail route for repair.
+
+**Rationale**: The current findings workflow already has audited assignment and lifecycle actions on the detail surface. Recreating those actions on the hygiene report would create a second mutation surface and complicate action hierarchy, RBAC, and audit semantics.
+
+**Alternatives considered**:
+
+- Add inline reassignment actions to the report. Rejected because the report would stop being a pure repair-identification surface and would duplicate the existing finding workflow UI.
+- Add a bulk repair action. Rejected because the spec explicitly keeps automation and redistribution out of scope for v1.

+# Feature Specification: Assignment Hygiene & Stale Work Detection
+
+**Feature Branch**: `225-assignment-hygiene`  
+**Created**: 2026-04-22  
+**Status**: Draft  
+**Input**: User description: "Assignment Hygiene & Stale Work Detection"
+
+## Spec Candidate Check *(mandatory — SPEC-GATE-001)*
+
+- **Problem**: Findings can enter a hidden decay path after assignment. Work disappears from the assignee's personal queue when access changes, remains pointed at assignees who no longer have tenant access or were soft-deleted, or stays `in_progress` long after meaningful work stopped.
+- **Today's failure**: Operators can trust `My Findings`, intake, and notifications only until assignment truth drifts. Broken or stalled work then becomes harder to see than normal backlog, so accountability gaps survive longer than they should.
+- **User-visible improvement**: One workspace-safe hygiene report and one overview signal expose broken assignments and stale in-progress work with clear reasons, owner context, and one drilldown into the existing finding detail for repair.
+- **Smallest enterprise-capable version**: Add one canonical read-first hygiene report, one bounded derived hygiene reason vocabulary over existing finding and membership truth, and one workspace overview drill-in signal. Reuse existing finding detail actions for repair instead of inventing a new fixing workflow.
+- **Explicit non-goals**: No automatic reassignment, no load balancing, no absence-management model, no new notification channel, no comments or ticketing, no bulk repair workflow, and no second findings state store.
+- **Permanent complexity imported**: One canonical hygiene report page, one overview summary signal, one bounded derived hygiene-query contract, one small hygiene reason vocabulary, and focused regression coverage for cross-tenant visibility, classification, and drill-in safety.
+- **Why now**: Spec 219 clarified owner versus assignee, Spec 221 created `My Findings`, Spec 222 created shared intake, and Spec 224 added notifications. The next missing slice is to keep those workflow surfaces trustworthy after work is assigned and begins.
+- **Why not local**: A tenant-local filter or one extra badge would still leave hidden backlog distributed across many tenants and would not answer the cross-tenant question "which assigned work is no longer healthy right now?"
+- **Approval class**: Core Enterprise
+- **Red flags triggered**: One bounded derived reason vocabulary and one new canonical cross-tenant report surface. Scope remains acceptable because the feature derives from existing finding, membership, and lifecycle truth instead of adding persistence or automation.
+- **Score**: Nutzen: 2 | Dringlichkeit: 2 | Scope: 2 | Komplexität: 1 | Produktnähe: 2 | Wiederverwendung: 1 | **Gesamt: 10/12**
+- **Decision**: approve
+
+## Spec Scope Fields *(mandatory)*
+
+- **Scope**: canonical-view
+- **Primary Routes**:
+  - `/admin/findings/hygiene` as the new canonical findings hygiene report
+  - `/admin` as the workspace overview where the hygiene signal links into the report
+  - `/admin/t/{tenant}/findings/{finding}` as the existing repair drilldown destination
+- **Data Ownership**: Tenant-owned findings remain the only source of truth. The hygiene report is a derived cross-tenant view over existing finding lifecycle, responsibility, due-state, workflow-activity, tenant-entitlement, and assignee user soft-delete truth. No new persisted hygiene table or flag is introduced.
+- **RBAC**: Workspace membership is required for the canonical hygiene report in the admin plane. The report route itself remains available to workspace members and renders only rows, counts, filter values, and drill-in CTAs for tenants they may already inspect; a workspace member with zero visible hygiene records receives an empty report rather than a route-level `403`. Repair actions continue to reuse the existing tenant findings assign workflow and authorization on the finding detail surface. Non-members and out-of-scope users remain deny-as-not-found. Members missing the required capability remain forbidden on protected drilldown destinations.
+
+For canonical-view specs, the spec MUST define:
+
+- **Default filter behavior when tenant-context is active**: The hygiene report always keeps its fixed hygiene scope. When an active tenant context exists, the page additionally applies that tenant as a default prefilter while allowing the operator to clear only the tenant prefilter, not the hygiene scope itself.
+- **Explicit entitlement checks preventing cross-tenant leakage**: Rows, counts, filter values, summary drill-ins, and empty-state hints are derived only from findings in tenants the current user may already inspect. Hidden tenants contribute nothing to the hygiene report or the overview signal.
+
+## 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 |
+|---|---|---|---|---|---|---|
+| Findings hygiene report | yes | Native Filament page + existing table, filter, text-column, and empty-state primitives | Same findings workflow family as `My Findings`, intake, and finding detail | table, fixed hygiene reason views, row drill-in, tenant prefilter, summary counts | no | Read-first report only; no new mutation family |
+| Workspace overview hygiene signal | yes | Native Filament widget or summary primitives | Same workspace-overview attention family as other `/admin` signals | embedded summary, drill-in CTA, visible-scope counts | no | Small entry signal only; not a second report |
+
+## 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 |
+|---|---|---|---|---|---|---|---|
+| Findings hygiene report | Primary Decision Surface | A workspace operator reviews decayed assignments or stalled in-progress work and decides what needs reassignment or manual follow-up first | Tenant, finding summary, hygiene reason, owner, assignee, due or overdue state, and last meaningful workflow activity | Full finding detail, evidence, audit trail, exception context, and existing assignment actions after opening the record | Primary because this is the first dedicated cross-tenant repair surface for work that has fallen between intake, personal execution, and normal notifications | Follows the operator's repair workflow instead of forcing tenant-by-tenant hunting for broken work | Removes repeated search across `My Findings`, intake, tenant lists, and overdue-only scans |
+| Workspace overview hygiene signal | Secondary Context Surface | An operator lands on `/admin` and needs to know whether workflow hygiene already requires attention before choosing another work surface | Current unique hygiene issue count, a short description derived from broken-assignment and stale-in-progress counts, and one CTA into the report | Full report and finding detail after drill-in | Secondary because it points to the real repair surface rather than becoming its own queue | Keeps workspace home aligned with findings workflow integrity | Avoids opening multiple findings pages just to discover whether hidden backlog exists |
+
+## 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 |
+|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
+| Findings hygiene report | List / Table / Bulk | Read-only Registry / Report Surface | Open the affected finding and repair responsibility from the existing detail workflow | Finding | required | Utility filters and tenant-prefilter clear affordances stay outside row action noise | none on the report; dangerous actions remain on the existing finding detail | /admin/findings/hygiene | /admin/t/{tenant}/findings/{finding} | Active workspace, optional active-tenant prefilter, tenant column, hygiene reason filters | Findings / Finding | Which findings have broken assignment truth or stalled in-progress work, and why | none |
+| Workspace overview hygiene signal | Utility / System | Read-only Registry / Report Surface | Open the hygiene report | Explicit summary CTA | forbidden | Summary strip only | none | /admin | /admin/findings/hygiene | Active workspace and visible-scope counts | Findings hygiene | Whether any visible findings workflow hygiene issue already needs attention | Embedded summary drill-in that stays read-only and points into the canonical report rather than becoming its own queue surface |
+
+## 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 |
+|---|---|---|---|---|---|---|---|---|---|---|
+| Findings hygiene report | Workspace operator, tenant manager, or findings workflow steward | Decide which broken or stalled finding needs repair first | Read-first workflow hygiene report | Which visible findings are no longer in a healthy execution path, and what kind of repair do they need? | Tenant, finding summary, owner, assignee when present, hygiene reason, due or overdue state, and last meaningful workflow activity | Raw evidence, run context, audit trail, and full lifecycle history after opening the finding | lifecycle, responsibility validity, work freshness, due urgency | none on the report itself; existing tenant finding surfaces keep their current mutation scopes | Open finding, apply filters, clear tenant prefilter | none |
+| Workspace overview hygiene signal | Workspace member with findings visibility | Decide whether findings workflow hygiene already needs review now | Summary drill-in | Do I need to repair hidden or stalled findings work before I continue elsewhere? | Unique hygiene issue count, a short description derived from broken-assignment and stale-in-progress counts, and one CTA | none | issue presence, reason composition, visible scope | none | Open findings hygiene | none |
+
+## Proportionality Review *(mandatory when structural complexity is introduced)*
+
+- **New source of truth?**: no
+- **New persisted entity/table/artifact?**: no
+- **New abstraction?**: yes — one bounded derived hygiene-query contract over existing finding lifecycle, responsibility, tenant-entitlement, and assignee user soft-delete truth
+- **New enum/state/reason family?**: yes — one bounded derived hygiene reason vocabulary for `broken assignment` and `stale in progress`
+- **New cross-domain UI framework/taxonomy?**: no
+- **Current operator problem**: Assigned findings can disappear from personal execution surfaces or remain stuck in `in_progress` without one truthful repair view, which weakens trust in the broader findings workflow.
+- **Existing structure is insufficient because**: `My Findings` answers "what is assigned to me," intake answers "what is still unassigned," and notifications answer "what just happened." None of those surfaces answers "what assigned or in-progress work is now unhealthy across my visible tenants?"
+- **Narrowest correct implementation**: Add one derived cross-tenant hygiene report and one overview signal, reuse existing detail actions for repair, and keep hygiene truth derived rather than persisted.
+- **Ownership cost**: Ongoing maintenance for one small reason vocabulary, one canonical report query, overview summary assertions, and regression coverage for tenant-safe classification.
+- **Alternative intentionally rejected**: Automatic reassignment, reminder loops, or a new workflow engine were rejected because they act on the problem before operators have one trustworthy view of the problem.
+- **Release truth**: Current-release truth. This feature makes the current findings workflow honest and repairable now rather than preparing a future autonomous routing system.
+
+### Compatibility posture
+
+This feature assumes a pre-production environment.
+
+Backward compatibility, legacy aliases, migration shims, historical fixtures, and compatibility-specific tests are out of scope unless explicitly required by this spec.
+
+Canonical replacement is preferred over preservation.
+
+## Testing / Lane / Runtime Impact *(mandatory for runtime behavior changes)*
+
+- **Test purpose / classification**: Feature
+- **Validation lane(s)**: fast-feedback, confidence
+- **Why this classification and these lanes are sufficient**: The feature is proven by visible operator behavior on one canonical cross-tenant report and one workspace summary signal. Focused feature coverage is sufficient to prove classification truth, visibility boundaries, tenant-prefilter behavior, and drill-in safety without introducing browser or heavy-governance cost.
+- **New or expanded test families**: Add focused hygiene-report visibility tests, hygiene-classification tests for broken assignment and stale work, overview-signal count tests, and tenant-prefilter empty-state tests.
+- **Fixture / helper cost impact**: Moderate. Tests need findings with explicit owner and assignee combinations, stale and fresh workflow timestamps, entitlement-lost and soft-deleted assignee cases, and mixed visible versus hidden tenant memberships.
+- **Heavy-family visibility / justification**: none
+- **Special surface test profile**: global-context-shell
+- **Standard-native relief or required special coverage**: Ordinary feature coverage is sufficient, plus explicit proof that healthy unassigned intake backlog does not leak into the hygiene report, hidden-tenant findings never appear in rows or counts, and one finding with multiple hygiene reasons is counted once.
+- **Reviewer handoff**: Reviewers must confirm that broken-assignment classification is derived from current tenant entitlement and assignee soft-delete truth rather than stale cached assumptions, that stale work does not collapse into overdue-only logic, that report rows remain read-first, and that the overview signal matches the canonical report under the same visible scope.
+- **Budget / baseline / trend impact**: none
+- **Escalation needed**: none
+- **Active feature PR close-out entry**: Guardrail
+- **Planned validation commands**:
+  - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`
+  - `cd apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+
+## User Scenarios & Testing *(mandatory)*
+
+### User Story 1 - See broken assignments in one repair view (Priority: P1)
+
+As a workspace operator, I want one cross-tenant report of findings whose assignment is no longer actionable, so I can repair hidden backlog before it silently disappears from personal work surfaces.
+
+**Why this priority**: This is the smallest slice that closes the trust gap left after assignment. If broken assignments remain invisible, the newer findings queues and notifications are not reliable enough to operate on.
+
+**Independent Test**: Can be fully tested by seeding assigned findings where the assignee no longer has current tenant access or the assignee user record is soft-deleted, then verifying that the report shows those rows with owner context and safe drilldown.
+
+**Acceptance Scenarios**:
+
+1. **Given** an open finding is still assigned but the assignee no longer has current entitlement to inspect that tenant, **When** an entitled workspace operator opens the hygiene report, **Then** the finding appears with the hygiene reason `broken assignment`.
+2. **Given** an open finding is assigned to a user whose account was soft-deleted, **When** an entitled workspace operator opens the hygiene report, **Then** the finding appears with the hygiene reason `broken assignment`.
+3. **Given** a finding belongs to a hidden tenant, **When** the current user opens the hygiene report, **Then** that finding contributes nothing to rows, counts, filter values, or empty-state hints.
+
+---
+
+### User Story 2 - Detect stalled in-progress work before it becomes hidden backlog (Priority: P1)
+
+As a findings workflow steward, I want stale `in_progress` work surfaced separately from normal overdue work, so I can intervene on work that stopped moving without assuming every overdue finding is stale.
+
+**Why this priority**: Stale work detection is the second half of hygiene. Without it, the product can only detect broken assignees, not stalled execution.
+
+**Independent Test**: Can be fully tested by seeding fresh and stale `in_progress` findings across visible tenants and verifying that only stale findings appear with the correct reason while fresh or merely overdue findings stay out of the report.
+
+**Acceptance Scenarios**:
+
+1. **Given** an open finding has remained `in_progress` with no meaningful workflow activity for seven consecutive days, **When** an entitled workspace operator opens the hygiene report, **Then** the finding appears with the hygiene reason `stale in progress`.
+2. **Given** an open finding is overdue but has recent meaningful workflow activity, **When** an entitled workspace operator opens the hygiene report, **Then** the finding does not appear solely because it is overdue.
+3. **Given** one finding has both a broken assignment and stale in-progress work, **When** the hygiene report is rendered, **Then** the finding appears as a single row with both reasons visible and contributes one unique issue to summary counts.
+
+---
+
+### User Story 3 - Discover hygiene issues from the workspace overview (Priority: P2)
+
+As a workspace member with findings visibility, I want the workspace overview to show whether findings workflow hygiene already needs attention, so I can enter the repair report without scanning multiple pages.
+
+**Why this priority**: The canonical report is valuable only if operators can discover it in normal workspace navigation. A small summary signal is the narrowest discoverability improvement.
+
+**Independent Test**: Can be fully tested by seeding both visible hygiene issues and a zero-issue visible scope, loading `/admin`, verifying the attention-state and calm-state signal variants, and following the CTA into the canonical report.
+
+**Acceptance Scenarios**:
+
+1. **Given** the current user has visible hygiene issues across one or more tenants, **When** the user opens `/admin`, **Then** the workspace overview shows one findings hygiene signal with the correct unique issue count.
+2. **Given** the current user has no visible hygiene issues, **When** the user opens `/admin`, **Then** the workspace overview shows the same findings hygiene signal in a calm state with zero visible issues, calm descriptive copy, and the canonical CTA into the report.
+3. **Given** the current user opens that signal, **When** the CTA is used, **Then** the user lands on `/admin/findings/hygiene` with the same visible-scope truth.
+
+### Edge Cases
+
+- A single finding may have multiple hygiene reasons at once; the report must show one row per finding and surface all applicable reasons without duplicating counts.
+- An unassigned finding in normal intake scope is not a hygiene issue by itself; it remains handled by the intake workflow unless it independently qualifies as stale `in_progress` work.
+- A resolved, closed, or otherwise terminal finding must leave the hygiene report immediately even if it was previously stale or broken.
+- An active tenant prefilter may produce an empty hygiene report while other visible tenants still contain issues; the empty state must explain the filter boundary instead of claiming no issues exist anywhere.
+- A finding may remain accountable to an owner even when its assignee is broken; owner context must stay visible so repair can start from the correct person.
+
+## Requirements *(mandatory)*
+
+**Constitution alignment (required):** This feature adds no Microsoft Graph calls, no new write path, and no new `OperationRun`. It introduces one canonical admin-plane report and one overview signal derived from existing finding, lifecycle, membership, and assignee user soft-delete truth. Repair continues through existing tenant findings actions and their current audit coverage.
+
+**Constitution alignment (TEST-GOV-001):** The proof burden is focused feature coverage for hygiene classification, visibility boundaries, tenant-prefilter behavior, workspace overview signal consistency, and drill-in safety. No browser or heavy-governance lane is required.
+
+**Constitution alignment (RBAC-UX):** The feature operates in the admin `/admin` plane for the canonical report and overview signal, with tenant entitlement enforced per finding before disclosure and before drilldown to `/admin/t/{tenant}/findings/{finding}`. Non-members or out-of-scope users continue to receive `404`. In-scope users lacking the existing findings view capability continue to receive `403` on protected drilldown destinations, while the workspace report itself renders only the rows they may inspect. Repair actions continue to reuse the existing findings assign authorization on the tenant detail surface. No raw capability strings, role checks, or second permission system may be introduced.
+
+**Constitution alignment (UI-FIL-001):** The report and overview signal must use native Filament page, table, filter, stat, and empty-state primitives or existing shared UI helpers. Hygiene reasons remain plain-text reason labels in the report and do not introduce a new BADGE-001 status mapping. No local status language, ad hoc color system, or custom badge markup may be introduced for hygiene reasons.
+
+**Constitution alignment (UI-NAMING-001):** The canonical operator-facing vocabulary is `Findings hygiene`, `Broken assignment`, `Stale in progress`, `Open finding`, and `Open findings hygiene`. Terms such as `repair record`, `workflow defect`, or `queue health object` must not replace the finding domain language in primary labels.
+
+**Constitution alignment (DECIDE-001):** The hygiene report is a primary repair surface because it answers one operator question in one place: which findings workflow items are no longer healthy? The overview signal is a secondary drill-in only and must not become a second report.
+
+**Constitution alignment (UI-CONST-001 / UI-SURF-001 / ACTSURF-001 / HDR-001):** The hygiene report has exactly one primary inspect model: the finding. Row click is required. There is no redundant `View` action. Utility controls such as tenant filter and hygiene reason filters stay outside row action noise. Dangerous lifecycle actions remain on the existing finding detail instead of being promoted into the report. The workspace overview signal remains a summary drill-in surface with one explicit CTA.
+
+**Constitution alignment (UI-SEM-001 / LAYER-001 / TEST-TRUTH-001):** Direct mapping from current queues is insufficient because healthy assigned work, unassigned intake work, and unhealthy hidden backlog are different operator questions. This feature solves that by adding one derived hygiene interpretation over existing domain truth rather than a persisted workflow mirror. Tests must prove visible workflow consequences, not thin presentational indirection.
+
+### Functional Requirements
+
+- **FR-001**: The system MUST provide a canonical findings hygiene report at `/admin/findings/hygiene` for the current user's visible tenant scope.
+- **FR-002**: The hygiene report MUST include only non-terminal findings that satisfy at least one hygiene reason. It MUST NOT duplicate healthy assigned work or ordinary intake backlog.
+- **FR-003**: The feature MUST derive hygiene truth from existing finding lifecycle, responsibility, tenant-entitlement, and assignee user soft-delete truth without introducing a persisted hygiene flag, table, or workflow state.
+- **FR-004**: The system MUST classify `broken assignment` when a non-terminal finding still has an assignee but that assignee cannot currently act on the finding because they no longer have current tenant entitlement or the assignee user record is soft-deleted.
+- **FR-005**: The system MUST classify `stale in progress` when a non-terminal finding remains `in_progress` with no meaningful workflow activity for seven consecutive days.
+- **FR-006**: Meaningful workflow activity for stale detection MUST reset when responsibility or lifecycle state changes in a way that materially advances the finding, including assignment changes, start-progress transitions, or reopen-driven lifecycle resets.
+- **FR-007**: Overdue status and stale-work status MUST remain separate dimensions. A finding MUST NOT enter the hygiene report solely because it is due soon or overdue.
+- **FR-008**: If one finding satisfies multiple hygiene reasons, the report MUST render that finding once and show all applicable reasons without duplicating unique issue counts.
+- **FR-009**: The report MUST show by default the tenant, finding summary, accountable owner, current assignee when present, hygiene reason or reasons, due or overdue state, and last meaningful workflow activity timestamp.
+- **FR-010**: The hygiene report MUST remain read-first. Its only primary inspect model is the finding, reached through row click into the existing tenant finding detail route.
+- **FR-011**: The hygiene report MUST NOT introduce inline reassignment, bulk reassignment, auto-fix actions, or a second repair workflow. Existing tenant finding actions remain the place where repair happens.
+- **FR-012**: The workspace overview at `/admin` MUST expose one findings hygiene summary signal that shows the current unique visible issue count, a short description derived from broken-assignment and stale-in-progress counts, and drills into the canonical hygiene report. When the current user has no visible hygiene issues, the same signal MUST render calm-state copy with zero visible issues and the same canonical CTA.
+- **FR-013**: When tenant context is active, the hygiene report MUST prefilter to that tenant while preserving the fixed hygiene scope. Operators MUST be able to clear only the tenant prefilter.
+- **FR-014**: Hidden tenants MUST contribute nothing to hygiene rows, counts, filter values, or empty-state hints.
+- **FR-015**: Existing `My Findings` and intake contracts MUST remain unchanged. Healthy assigned work stays discoverable through `My Findings`, normal unassigned backlog stays discoverable through intake, and the hygiene report exists only for findings workflow items that would otherwise become hidden or misleading.
+- **FR-016**: The report MUST provide fixed reason filters for `All issues`, `Broken assignment`, and `Stale in progress`.
+- **FR-017**: The filtered-empty state MUST explain when the current tenant prefilter is narrowing visible issues and provide exactly one CTA that clears the tenant prefilter back to all visible tenants.
+- **FR-018**: The feature MUST NOT add automatic reassignment, scheduled escalation, or a second notification channel. Any later automation MUST be a separate spec built on top of this repair surface.
+
+## UI Action Matrix *(mandatory when Filament is changed)*
+
+| Surface | Location | Header Actions | Inspect Affordance (List/Table) | Row Actions (max 2 visible) | Bulk Actions (grouped) | Empty-State CTA(s) | View Header Actions | Create/Edit Save+Cancel | Audit log? | Notes / Exemptions |
+|---|---|---|---|---|---|---|---|---|---|---|
+| Findings hygiene report | `/admin/findings/hygiene` | none | Full-row open into finding detail | none; row click is the only primary inspect affordance | none | `Clear tenant filter` only when a tenant prefilter causes the empty state; otherwise none | n/a | n/a | No new mutation audit because the surface stays read-only | Action Surface Contract satisfied. No redundant `View` action, no empty action groups, and no dangerous action promoted into the report. |
+| Workspace overview hygiene signal | `/admin` | none | Explicit summary CTA into the report | none | none | none | n/a | n/a | No new mutation audit because the surface stays read-only | Embedded summary drill-in only. It points to the canonical report and does not introduce a second work surface. |
+
+### Key Entities *(include if feature involves data)*
+
+- **Finding hygiene issue**: A derived workflow integrity issue attached to a visible non-terminal finding when assignment is broken or in-progress work has stalled.
+- **Broken assignment**: A derived reason indicating that the assigned operator can no longer act on the finding according to current tenant-entitlement or assignee user soft-delete truth.
+- **Stale in-progress work**: A derived reason indicating that a finding has remained `in_progress` without meaningful workflow activity for the defined stale window.
+
+## Success Criteria *(mandatory)*
+
+### Measurable Outcomes
+
+- **SC-001**: In acceptance review, an operator can identify why a finding appears on the hygiene report and open the correct finding in one interaction.
+- **SC-002**: 100% of covered automated classification tests include broken-assignment and stale findings while excluding healthy assigned work, ordinary intake backlog, and merely overdue-but-active findings.
+- **SC-003**: 100% of covered visibility tests show that hidden-tenant findings contribute nothing to hygiene rows, counts, filter values, or overview signals.
+- **SC-004**: 100% of covered summary tests show that the workspace overview hygiene count matches the canonical report's unique visible issue count under the same scope.
+
+## Assumptions
+
+- Existing finding lifecycle and audit-related timestamps expose enough signal to derive last meaningful workflow activity without introducing new persistence.
+- The v1 stale threshold is fixed at seven days of inactivity for `in_progress` findings.
+- Broken-assignment truth in v1 uses only current tenant entitlement and assignee user soft-delete truth already modeled by the product; no broader availability, absence, or capacity model is introduced.
+- Repair continues through the existing finding detail and responsibility actions rather than directly from the hygiene report.
+
+## Non-Goals
+
+- Automatically reassign findings, clear assignees, or mutate workflow state from the hygiene report.
+- Add reminder loops or notification behavior beyond the separate notifications and escalation spec.
+- Introduce team-capacity balancing, absence management, or load-distribution logic.
+- Fold resolved-versus-verified outcome semantics into this spec.
+- Create a second findings history, audit, or workflow-state store.
+
+## Dependencies
+
+- Spec 111 remains the source of truth for finding lifecycle, due state, and open versus terminal semantics.
+- Spec 219 remains the source of truth for owner-versus-assignee meaning.
+- Spec 221 remains the source of truth for healthy personal assigned-work discovery in `My Findings`.
+- Spec 222 remains the source of truth for normal unassigned findings intake.
+- Spec 224 remains the adjacent notification slice that points operators toward work changes but does not replace a repair view for decayed assignments or stalled work.

+# Tasks: Assignment Hygiene & Stale Work Detection
+
+**Input**: Design documents from `/specs/225-assignment-hygiene/`
+**Prerequisites**: `plan.md`, `spec.md`, `research.md`, `data-model.md`, `contracts/assignment-hygiene.logical.openapi.yaml`, `quickstart.md`
+
+**Tests**: Required. This feature changes runtime behavior in a new canonical Filament findings page, a shared derived-query service, workspace overview signal rendering, and tenant-safe disclosure behavior, so Pest coverage must be added in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`, `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`, and `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`.
+**Operations**: No new `OperationRun` is introduced. The feature remains read-only and reuses the existing tenant finding detail repair path plus current audit truth.
+**RBAC**: The canonical hygiene report and overview signal stay on the admin `/admin` plane, while repair drilldown stays on `/admin/t/{tenant}/findings/{finding}`. The implementation must preserve non-member and out-of-scope workspace `404`, tenant-safe suppression of hidden-tenant rows and counts inside an otherwise available report, in-scope missing-capability `403` on protected drilldown destinations, and the existing findings assign authorization on the tenant detail surface.
+**UI / Surface Guardrails**: `Findings hygiene report` is a `standard-native-filament` surface and the workspace overview signal is a `global-context-shell` seam. Both must keep one calm drill-in path only, with no inline mutation drift.
+**Filament UI Action Surfaces**: `FindingsHygieneReport` is a new read-only Filament page with one inspect model only: the finding. There must be no redundant `View` action, no inline repair action, no bulk action group, and no destructive action on the report surface.
+**Badges**: Existing finding lifecycle and severity semantics remain authoritative. Hygiene reasons remain plain-text reason labels in the report, so BADGE-001 is not extended and no page-local status mapping is introduced.
+
+**Organization**: Tasks are grouped by user story so each slice stays independently testable. Recommended delivery order is `US1 -> US2 -> US3`, because broken-assignment visibility is the smallest MVP repair slice, stale-work detection builds on the same canonical report second, and overview discoverability is safest after the report truth is established.
+
+## Test Governance Checklist
+
+- [x] Lane assignment is named and is the narrowest sufficient proof for the changed behavior.
+- [x] New or changed tests stay in the smallest honest family, and any heavy-governance or browser addition is explicit.
+- [x] Shared helpers, factories, seeds, fixtures, and context defaults stay cheap by default; any widening is isolated or documented.
+- [x] Planned validation commands cover the change without pulling in unrelated lane cost.
+- [x] The declared surface test profile or `standard-native-filament` relief is explicit.
+- [x] Any material budget, baseline, trend, or escalation note is recorded in the active spec or PR.
+
+## Phase 1: Setup (Report And Test Scaffolding)
+
+**Purpose**: Prepare the shared page, service, and focused regression files used across all stories.
+
+- [x] T001 [P] Create the findings hygiene page scaffold in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php`
+- [x] T002 [P] Create the findings hygiene Blade shell in `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php`
+- [x] T003 [P] Create the shared hygiene service scaffold in `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php`
+- [x] T004 [P] Create focused Pest scaffolding in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`, `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`, and `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+
+**Checkpoint**: The shared page, Blade view, service, and focused test files exist and are ready for implementation work.
+
+---
+
+## Phase 2: Foundational (Blocking Report Route And Shared Classification Seam)
+
+**Purpose**: Establish the canonical route treatment, shared visible-tenant scope, and baseline report contract every story depends on.
+
+**⚠️ CRITICAL**: No user story work should begin until this phase is complete.
+
+- [x] T005 Add `/admin/findings/hygiene` to workspace-scoped tenant-selection bypass and navigation handling in `apps/platform/app/Support/Middleware/EnsureFilamentTenantSelected.php`
+- [x] T006 Implement visible-tenant scoping, unique issue counting, and fixed reason filter baseline in `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php`
+- [x] T007 Implement the canonical report table with default-visible tenant, finding summary, owner, assignee, due-state, hygiene reasons, last meaningful workflow activity columns, row drilldown into `FindingResource`, and read-first inspect behavior in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php`
+- [x] T008 Add foundational tenant-safe report access, empty-report behavior for workspace members with zero visible hygiene scope, default-visible finding summary and last-activity coverage, and drilldown coverage in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`
+
+**Checkpoint**: The canonical report route, shared hygiene query seam, and base tenant-safe read path are available for all stories.
+
+---
+
+## Phase 3: User Story 1 - See broken assignments in one repair view (Priority: P1) 🎯 MVP
+
+**Goal**: Show cross-tenant assigned findings that are no longer actionable because the current assignee cannot work them anymore.
+
+**Independent Test**: Seed assigned findings where the assignee lost tenant entitlement or the user was soft-deleted, open `/admin/findings/hygiene`, and verify one visible row per broken finding with owner context and safe drilldown.
+
+### Tests for User Story 1
+
+- [x] T009 [P] [US1] Add broken-assignment report visibility and hidden-tenant rows, counts, filter values, and empty-state suppression coverage in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`
+- [x] T010 [P] [US1] Add broken-assignment classification coverage for entitlement loss and soft-deleted users in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`
+
+### Implementation for User Story 1
+
+- [x] T011 [US1] Implement `broken assignment` classification from current tenant entitlement and soft-deleted assignee truth in `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php`
+- [x] T012 [US1] Render finding summary, owner, assignee, due-state, last meaningful workflow activity, and plain-text `Broken assignment` reason visibility on the canonical report in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php` and `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php`
+- [x] T013 [US1] Keep the report drill-in aligned to the existing tenant findings repair path in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php`
+
+**Checkpoint**: User Story 1 is independently functional and operators can see broken assignments in one cross-tenant repair view.
+
+---
+
+## Phase 4: User Story 2 - Detect stalled in-progress work before it becomes hidden backlog (Priority: P1)
+
+**Goal**: Surface genuinely stalled `in_progress` work separately from healthy or merely overdue findings.
+
+**Independent Test**: Seed fresh and stale `in_progress` findings, open `/admin/findings/hygiene`, and verify that only stale work appears, overdue-but-active findings stay out, and one finding with two reasons remains one row.
+
+### Tests for User Story 2
+
+- [x] T014 [P] [US2] Add stale-work versus overdue-but-active and reopen-driven stale-reset classification coverage in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`
+- [x] T015 [P] [US2] Add regression coverage that healthy assigned work and ordinary intake backlog remain excluded from the hygiene report in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`
+- [x] T016 [P] [US2] Add fixed reason filter coverage for `All issues`, `Broken assignment`, and `Stale in progress` in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`
+- [x] T017 [P] [US2] Add multi-reason single-row, unique-count, and filtered-empty-state `Clear tenant filter` CTA coverage in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php` and `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+
+### Implementation for User Story 2
+
+- [x] T018 [US2] Derive last meaningful workflow activity from `in_progress_at`, `reopened_at`, and existing finding workflow audit events in `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php` and `apps/platform/app/Services/Findings/FindingWorkflowService.php`
+- [x] T019 [US2] Implement `stale in progress` classification and multi-reason aggregation in `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php`
+- [x] T020 [US2] Render finding summary, last meaningful workflow activity, and plain-text `Stale in progress` combined-reason visibility without introducing a new workflow taxonomy in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php` and `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php`
+- [x] T021 [US2] Add the tenant-prefilter empty-state explanation and `Clear tenant filter` CTA in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php` and `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php`
+
+**Checkpoint**: User Story 2 is independently functional and stale in-progress work is distinguished from healthy or merely overdue findings.
+
+---
+
+## Phase 5: User Story 3 - Discover hygiene issues from the workspace overview (Priority: P2)
+
+**Goal**: Expose the canonical findings hygiene truth from `/admin` so operators can reach the repair surface without scanning multiple pages first.
+
+**Independent Test**: Seed visible hygiene issues and a zero-issue visible scope, open `/admin`, verify the attention-state summary, calm-state behavior, and CTA, and follow the signal into `/admin/findings/hygiene` with matching visible-scope truth.
+
+### Tests for User Story 3
+
+- [x] T022 [P] [US3] Add workspace overview signal count, descriptive summary from broken/stale counts, calm-state, visible-scope, and CTA routing coverage in `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+
+### Implementation for User Story 3
+
+- [x] T023 [US3] Add the findings hygiene overview signal with unique issue counts, a short description derived from broken/stale counts, and CTA into the canonical report in `apps/platform/app/Support/Workspaces/WorkspaceOverviewBuilder.php`
+- [x] T024 [US3] Reuse the canonical hygiene service count truth for the overview signal in `apps/platform/app/Support/Workspaces/WorkspaceOverviewBuilder.php` and `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php`
+
+**Checkpoint**: User Story 3 is independently functional and the workspace overview reliably points operators into the canonical hygiene report.
+
+---
+
+## Phase 6: Polish & Cross-Cutting Concerns
+
+**Purpose**: Finish guardrail alignment, formatting, and focused verification across the full feature.
+
+- [x] T025 Review operator-facing vocabulary, UI Action Matrix conformance, and guardrail alignment in `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php`, `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php`, and `apps/platform/app/Support/Workspaces/WorkspaceOverviewBuilder.php`
+- [x] T026 Run formatting for `apps/platform/app/Filament/Pages/Findings/FindingsHygieneReport.php`, `apps/platform/resources/views/filament/pages/findings/findings-hygiene-report.blade.php`, `apps/platform/app/Services/Findings/FindingAssignmentHygieneService.php`, `apps/platform/app/Support/Middleware/EnsureFilamentTenantSelected.php`, `apps/platform/app/Support/Workspaces/WorkspaceOverviewBuilder.php`, `apps/platform/app/Services/Findings/FindingWorkflowService.php`, `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`, `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`, and `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php` with `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent`
+- [x] T027 Run the focused verification workflow from `specs/225-assignment-hygiene/quickstart.md` against `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php`, `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php`, and `apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php`
+- [x] T028 Record the active feature PR close-out entry and proof commands in `specs/225-assignment-hygiene/plan.md` after implementation validation completes
+
+---
+
+## Dependencies & Execution Order
+
+### Phase Dependencies
+
+- **Setup (Phase 1)**: Starts immediately and prepares the shared page, view, service, and focused Pest files.
+- **Foundational (Phase 2)**: Depends on Setup and blocks all user stories until the canonical report route, shared hygiene query seam, and base tenant-safe report contract exist.
+- **User Story 1 (Phase 3)**: Depends on Foundational completion and is the recommended MVP cut.
+- **User Story 2 (Phase 4)**: Depends on Foundational completion and extends the same canonical report with stale-work truth.
+- **User Story 3 (Phase 5)**: Depends on Foundational completion and reuses the same service truth to expose overview discoverability.
+- **Polish (Phase 6)**: Depends on all desired user stories being complete.
+
+### User Story Dependencies
+
+- **US1**: No dependencies beyond Foundational.
+- **US2**: No hard dependency on US1 after Foundational, but it reuses the same report and service seams and should preserve the broken-assignment visibility already established there.
+- **US3**: No hard dependency on US1 or US2 after Foundational, but it must stay aligned with the canonical report truth they establish.
+
+### Within Each User Story
+
+- Write the story tests first and confirm they fail before implementation is considered complete.
+- Keep `FindingAssignmentHygieneService.php` authoritative for classification and counting before duplicating logic in the page or overview builder.
+- Finish story-level verification before moving to the next priority slice.
+
+### Parallel Opportunities
+
+- `T001`, `T002`, `T003`, and `T004` can run in parallel during Setup.
+- `T009` and `T010` can run in parallel for User Story 1.
+- `T014`, `T015`, `T016`, and `T017` can run in parallel for User Story 2.
+- `T022` and `T023` can run in parallel for User Story 3 once the foundational service seam is stable.
+
+---
+
+## Parallel Example: User Story 1
+
+```bash
+# User Story 1 tests in parallel
+T009 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php
+T010 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php
+```
+
+## Parallel Example: User Story 2
+
+```bash
+# User Story 2 tests in parallel
+T014 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php
+T015 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneClassificationTest.php
+T016 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php
+T017 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneReportTest.php

+T022 apps/platform/tests/Feature/Findings/FindingsAssignmentHygieneOverviewSignalTest.php
+T023 apps/platform/app/Support/Workspaces/WorkspaceOverviewBuilder.php
+```
+
+---
+
+## Implementation Strategy
+
+### MVP First (User Story 1 Only)
+
+1. Complete Phase 1: Setup.
+2. Complete Phase 2: Foundational.
+3. Complete Phase 3: User Story 1.
+4. Validate the feature against the focused US1 tests before widening the slice.
+
+### Incremental Delivery
+
+1. Ship US1 to close the hidden broken-assignment visibility gap.
+2. Add US2 to distinguish stale execution from ordinary overdue follow-up.
+3. Add US3 to make the canonical report discoverable from `/admin`.
+4. Finish with guardrail review, formatting, and the focused verification pack.
+
+### Parallel Team Strategy
+
+1. One contributor can scaffold the page and view while another prepares the focused Pest suites.
+2. After Foundational work lands, one contributor can implement broken-assignment classification while another prepares stale-work tests.
+3. Overview-signal work can proceed in parallel with final report polish once the shared hygiene service and canonical report truth are stable.
+
+---
+
+## Notes
+
+- `[P]` tasks target different files and can be worked independently once upstream blockers are cleared.
+- `[US1]`, `[US2]`, and `[US3]` map directly to the feature specification user stories.
+- The suggested MVP scope is Phase 1 through Phase 3 only.
+- All implementation tasks above follow the required checklist format with task ID, optional parallel marker, story label where applicable, and exact file paths.
