# Implementation Plan: Humanized Diagnostic Summaries for Governance Operations

**Branch**: `220-governance-run-summaries` | **Date**: 2026-04-20 | **Spec**: `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/220-governance-run-summaries/spec.md`
**Input**: Feature specification from `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/220-governance-run-summaries/spec.md`

**Note**: This plan keeps the work inside the existing canonical Monitoring run-detail, artifact-truth, and operator-explanation seams. The intended implementation is a bounded derived summary layer for governance operation runs, not a new persistence model, not a new lifecycle/state family, and not a new action or surface framework.

## Summary

Add one operator-first diagnostic summary to canonical governance run detail so baseline capture, baseline compare, evidence snapshot generation, tenant review composition, and review-pack generation runs explain dominant artifact impact, dominant cause, affected scale, artifact trustworthiness, and next action before raw diagnostics. The implementation will reuse `TenantlessOperationRunViewer`, `OperationRunResource`, `ArtifactTruthPresenter`, `OperatorExplanationBuilder`, `ReasonPresenter`, `OperationUxPresenter`, `SummaryCountsNormalizer`, and the current enterprise-detail builders, and it will introduce one small `GovernanceRunDiagnosticSummary` value object plus builder under `App\Support\OpsUx` so the canonical detail page can express affected-scale and multi-cause ranking without inventing a broader UI framework.

## Technical Context

**Language/Version**: PHP 8.4.15, Laravel 12, Filament v5, Livewire v4, Blade  
**Primary Dependencies**: Filament v5, Livewire v4, Pest v4, Laravel Sail, `TenantlessOperationRunViewer`, `OperationRunResource`, `ArtifactTruthPresenter`, `OperatorExplanationBuilder`, `ReasonPresenter`, `OperationUxPresenter`, `SummaryCountsNormalizer`, and the existing enterprise-detail builders  
**Storage**: PostgreSQL via existing `operation_runs` plus related `baseline_snapshots`, `evidence_snapshots`, `tenant_reviews`, and `review_packs`; no schema changes planned  
**Testing**: Pest v4 unit and feature tests, focused Monitoring/Filament/Authorization coverage  
**Validation Lanes**: fast-feedback, confidence
**Target Platform**: Dockerized Laravel web application via Sail locally and Linux containers in deployment
**Project Type**: Laravel monolith web application inside the `wt-plattform` monorepo  
**Performance Goals**: Preserve DB-only render behavior on canonical run detail, add no render-time external calls, avoid new query breadth, and keep first-pass operator comprehension inside a 10-15 second scan window  
**Constraints**: No new Graph calls, no new routes, no new `OperationRun` statuses or outcomes, no new `summary_counts` keys, no new notification surfaces, no new destructive actions, no cross-tenant leakage, and no duplication between decision summary and existing banners  
**Scale/Scope**: One canonical Monitoring detail surface, five governance run families, one bounded derived summary seam, and focused regression coverage for summary ordering, multi-cause explanation, zero-output runs, and authorization safety

## UI / Surface Guardrail Plan

- **Guardrail scope**: changed surfaces
- **Native vs custom classification summary**: native Filament + existing Monitoring detail primitives
- **Shared-family relevance**: governance run-detail family, operator explanation family, enterprise detail family
- **State layers in scope**: page, detail, URL-query
- **Handling modes by drift class or surface**: review-mandatory
- **Repository-signal treatment**: review-mandatory
- **Special surface test profiles**: monitoring-state-page
- **Required tests or manual smoke**: functional-core, state-contract, manual-smoke
- **Exception path and spread control**: retain the existing diagnostic-detail exception on canonical run detail; do not spread it into new surfaces or action patterns
- **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 | The feature reorders explanation on existing run and artifact truth only; inventory and snapshot ownership remain unchanged |
| Read/write separation | PASS | PASS | No new writes, previews, confirmations, or audit-log paths are introduced |
| Graph contract path | PASS | PASS | No new Graph calls or contract-registry changes |
| RBAC / workspace / tenant isolation | PASS | PASS | Canonical `/admin/operations/{run}` remains tenant-safe; non-members stay `404`; in-scope capability denials remain `403` |
| Run observability / Ops-UX | PASS | PASS | Existing `OperationRun` lifecycle, feedback surfaces, initiator rules, and summary-count contracts remain unchanged |
| Ops-UX summary counts | PASS | PASS | Existing flat numeric `summary_counts` stay canonical; the new summary only interprets them |
| Proportionality / no premature abstraction | PASS | PASS | One bounded run-summary helper is justified; no new framework, persistence, or state family is needed |
| Few layers / UI semantics | PASS | PASS | New logic stays downstream of `ArtifactTruthEnvelope` and `OperatorExplanationPattern`; no second truth source is introduced |
| Badge semantics (BADGE-001) | PASS | PASS | Existing badge domains remain canonical; the feature changes order and supporting copy only |
| Filament-native UI (UI-FIL-001) | PASS | PASS | Existing Filament detail page, sections, and enterprise-detail builders remain the implementation path |
| Action surface / inspect model | PASS | PASS | Canonical run detail remains the single inspect model; no new row, header, or bulk actions are introduced |
| Decision-first / OPSURF | PASS | PASS | The page remains a Tertiary Evidence / Diagnostics Surface, but its first read becomes operator-first |
| Test governance (TEST-GOV-001) | PASS | PASS | Proof stays in focused Monitoring feature coverage plus one narrow unit seam; no browser or heavy-governance expansion |
| Filament v5 / Livewire v4 compliance | PASS | PASS | The work stays entirely within the current Filament v5 + Livewire v4 stack |
| Provider registration / global search / assets | PASS | PASS | No panel/provider changes, `OperationRunResource` stays non-searchable, and no new assets are required |

## Test Governance Check

- **Test purpose / classification by changed surface**: `Feature` for canonical Monitoring run detail and authorization behavior; `Unit` only for the bounded run-summary builder or ranking helper if introduced
- **Affected validation lanes**: `fast-feedback`, `confidence`
- **Why this lane mix is the narrowest sufficient proof**: The feature is proven by operator-visible hierarchy, dominant-cause ordering, zero-output handling, and tenant-safe canonical run detail. That needs focused surface tests plus one narrow unit seam, not browser or heavy-governance breadth.
- **Narrowest proving command(s)**:
  - `cd /Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Monitoring/GovernanceOperationRunSummariesTest.php`
  - `cd /Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform && ./vendor/bin/sail artisan test --compact tests/Feature/Filament/OperationRunBaselineTruthSurfaceTest.php tests/Feature/Monitoring/ArtifactTruthRunDetailTest.php tests/Feature/Authorization/OperatorExplanationSurfaceAuthorizationTest.php tests/Feature/RunAuthorizationTenantIsolationTest.php`
  - `cd /Users/ahmeddarrazi/Documents/projects/wt-plattform/apps/platform && ./vendor/bin/sail artisan test --compact tests/Unit/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilderTest.php tests/Unit/Support/OperatorExplanation/OperatorExplanationBuilderTest.php`
- **Fixture / helper / factory / seed / context cost risks**: Shared fixture drift is the main risk. `BuildsGovernanceArtifactTruthFixtures` must stay opt-in, and any multi-cause seeded run helper should remain local to the Monitoring suite instead of becoming a repo-wide default.
- **Expensive defaults or shared helper growth introduced?**: no; all new scenario builders must require explicit run type, outcome, reason codes, and related artifact context
- **Heavy-family additions, promotions, or visibility changes**: none
- **Surface-class relief / special coverage rule**: `monitoring-state-page` coverage is required; existing `standard-native-filament` relief is not enough for summary-order assertions on the canonical detail page
- **Closing validation and reviewer handoff**: Reviewers must confirm summary-first order, no duplicate dominant-cause copy across banners and decision zone, zero-output runs staying non-green, cross-family consistency for shared cause classes, and `404` vs `403` semantics on the canonical route.
- **Budget / baseline / trend follow-up**: Low-to-moderate assertion growth within Monitoring and one new focused suite; no lane-budget follow-up expected unless helper sprawl begins
- **Review-stop questions**: Does the change stay inside current Monitoring detail seams? Did any new summary helper become broader than this surface needs? Did shared fixtures remain opt-in? Did any touched view leak inaccessible tenant or artifact hints?
- **Escalation path**: document-in-feature unless a second shared semantic layer, new persistence, or broad fixture default is proposed; then reject-or-split
- **Active feature PR close-out entry**: Guardrail
- **Why no dedicated follow-up spec is needed**: The expected suite cost and abstraction surface stay tightly bounded to one existing canonical detail page and its current governance run families

**Structure Decision**: Standard Laravel monolith. The work stays concentrated in the current Monitoring detail files, existing `Support/OpsUx` and UI helper seams, and focused Pest suites. No new base directory, panel, or package is needed.

## Complexity Tracking

| Violation | Why Needed | Simpler Alternative Rejected Because |
|-----------|------------|-------------------------------------|
| Bounded run-summary helper/value object | Needed to keep dominant-cause ranking, affected-scale mapping, and summary ordering out of `OperationRunResource` and page templates | Extending the resource/page inline would bury operation-family logic in Filament schema code and make regression coverage brittle |

## Proportionality Review

- **Current operator problem**: Canonical governance run detail is still too technical for first-pass operator decisions, especially when execution succeeded but artifact usability did not, or when several degraded causes exist together.
- **Existing structure is insufficient because**: Existing badges, explanation patterns, and raw payload sections require operators to synthesize impact, trust, and next action themselves. The missing piece is a first-pass run-detail summary that ranks cause and scale for this single surface.
- **Narrowest correct implementation**: Add one run-detail-specific summary object and builder inside `Support/OpsUx`, derived entirely from `OperationRun`, `ArtifactTruthEnvelope`, `OperatorExplanationPattern`, and existing count/context payloads.
- **Ownership cost created**: One small builder/value-object pair, one local set of dominance rules, and focused Monitoring/unit tests.
- **Alternative intentionally rejected**: Page-local copy patches and ad-hoc Filament facts only. That would duplicate operation-type logic, make hierarchy drift likely, and fail to protect cross-family consistency.
- **Release truth**: Current-release truth. This plan improves an existing trust surface now rather than preparing a future platform abstraction.

## Phase 0 Research

Research outcomes are captured in `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/220-governance-run-summaries/research.md`.

Key decisions:

- Keep canonical Monitoring run detail on `OperationRunResource` + `TenantlessOperationRunViewer`; do not create a second run-detail page.
- Treat `ArtifactTruthPresenter`, `OperatorExplanationBuilder`, and `ReasonPresenter` as the canonical semantic inputs.
- Introduce one bounded `GovernanceRunDiagnosticSummary` seam so the decision zone can express affected scale, dominant-cause ranking, and secondary-cause detail without overloading the Filament resource schema.
- Derive affected-scale cues from existing `summary_counts`, run `context`, and related artifact metadata; do not add schema or `summary_counts` contract changes.
- Keep lifecycle/context banners specialized and let the decision zone own the dominant explanation to avoid duplicated operator copy.
- Extend current Monitoring and authorization suites and keep multi-cause fixture helpers local or opt-in.

## Phase 1 Design

Design artifacts are created under `/Users/ahmeddarrazi/Documents/projects/wt-plattform/specs/220-governance-run-summaries/`:

- `research.md`: implementation-seam decisions, risks, and rejected alternatives
- `data-model.md`: logical model for the derived governance run summary, dominant-cause breakdown, and affected-scale cues
- `contracts/governance-run-summaries.logical.openapi.yaml`: internal logical contract for canonical operations list/detail rendering requirements
- `quickstart.md`: focused verification workflow for manual and automated validation

Design decisions:

- No schema migration is required; all summary state remains derived.
- The primary implementation seam is canonical run detail plus a small helper under `App\Support\OpsUx`, not a new cross-domain UI framework.
- Existing Filament action topology, route shape, authorization behavior, and destructive-action semantics remain unchanged.
- `OperationUxPresenter` remains the façade for memoized governance explanation state on run detail.
- Existing technical sections such as count diagnostics, failure payloads, evidence-gap detail, and artifact-truth detail remain available but must become secondary to the new summary block.

## Phase 1 Agent Context Update

Run:

- `.specify/scripts/bash/update-agent-context.sh copilot`

## Constitution Check — Post-Design Re-evaluation

- PASS — the design remains read-surface focused and does not introduce new write paths, Graph calls, assets, or authorization semantics.
- PASS — Livewire v4.0+ and Filament v5 constraints remain unchanged, no provider registration move is required, `OperationRunResource` remains non-searchable, and no new destructive actions or assets are introduced.

## Implementation Strategy

### Phase A — Introduce One Bounded Governance Run Summary Seam

**Goal**: Derive one operator-first run-detail summary without creating a second truth source.

| Step | File | Change |
|------|------|--------|
| A.1 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummary.php` | Add a small value object carrying headline, dominant cause, affected scale, trust statement, secondary causes, and next action |
| A.2 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilder.php` | Derive the summary from `OperationRun`, `ArtifactTruthPresenter`, `OperatorExplanationBuilder`, `ReasonPresenter`, `summary_counts`, and run context |
| A.3 | `apps/platform/app/Support/OpsUx/OperationUxPresenter.php` | Reuse existing memoization to expose the summary on canonical run detail without adding a new cache family |

### Phase B — Rewire Canonical Run Detail Around The First Decision

**Goal**: Make the decision zone lead with humanized diagnostic summaries and push raw diagnostics down.

| Step | File | Change |
|------|------|--------|
| B.1 | `apps/platform/app/Filament/Resources/OperationRunResource.php` | Update the enterprise-detail decision zone to render the new summary, affected-scale cue, and processing-versus-artifact split ahead of technical sections |
| B.2 | `apps/platform/app/Filament/Pages/Operations/TenantlessOperationRunViewer.php` | Keep scope, lifecycle, and restore banners specialized while removing duplicated dominant-cause copy from banner-level messaging |
| B.3 | `apps/platform/resources/views/filament/pages/operations/tenantless-operation-run-viewer.blade.php` or existing enterprise-detail view partials | Ensure the default reading order is summary first, supporting facts second, diagnostics third |

### Phase C — Add Stable Rules For Covered Governance Run Families

**Goal**: Keep summary language and affected-scale cues stable across the five scoped governance families.

| Step | File | Change |
|------|------|--------|
| C.1 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilder.php` | Add baseline-capture rules for blocked prerequisite, zero-subject capture, and unusable snapshot outcomes |
| C.2 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilder.php` | Add baseline-compare rules for suppressed output, ambiguous matches, evidence gaps, and strategy failures |
| C.3 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilder.php` | Add evidence snapshot, tenant review, and review-pack generation rules using existing related artifact truth plus run context |
| C.4 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilder.php` | Add one stable dominant-cause ranking rule so tied degraded runs do not reorder arbitrarily between renders |

### Phase D — Preserve Tenant Safety, Related Links, and Existing Action Topology

**Goal**: Improve explanation without changing route, RBAC, or action behavior.

| Step | File | Change |
|------|------|--------|
| D.1 | `apps/platform/app/Filament/Pages/Operations/TenantlessOperationRunViewer.php` | Keep canonical back-link lineage, active-tenant continuity, and grouped related navigation intact |
| D.2 | `apps/platform/app/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilder.php` | Ensure summary output suppresses inaccessible artifact or tenant hints when related navigation is not allowed |
| D.3 | Existing authorization tests and related-link helpers | Keep `404` vs `403` semantics unchanged and verify no new mutation affordances appear |

### Phase E — Protect The Surface With Focused Regression Coverage

**Goal**: Add the smallest test set that locks summary order, multi-cause behavior, zero-output runs, and authorization safety.

| Step | File | Change |
|------|------|--------|
| E.1 | `apps/platform/tests/Unit/Support/OpsUx/GovernanceRunDiagnosticSummaryBuilderTest.php` | Add unit coverage for dominant-cause ranking, affected-scale derivation, and next-step category mapping |
| E.2 | `apps/platform/tests/Feature/Monitoring/GovernanceOperationRunSummariesTest.php` | Add end-to-end run-detail coverage for multi-cause degraded runs, all-zero runs, cross-family parity, and diagnostics-secondary ordering |
| E.3 | `apps/platform/tests/Feature/Filament/OperationRunBaselineTruthSurfaceTest.php` and `apps/platform/tests/Feature/Monitoring/ArtifactTruthRunDetailTest.php` | Update existing assertions to match final summary-first wording and remove brittle duplication gaps |
| E.4 | `apps/platform/tests/Feature/Authorization/OperatorExplanationSurfaceAuthorizationTest.php` and `apps/platform/tests/Feature/RunAuthorizationTenantIsolationTest.php` | Extend canonical route coverage for tenant-safe summary rendering and inaccessible related navigation |
| E.5 | `cd apps/platform && ./vendor/bin/sail bin pint --dirty --format agent` plus focused Pest runs | Run formatting and the narrowest proving commands before implementation close-out |

## Key Design Decisions

### D-001 — Canonical run detail remains the only detailed run-inspection surface

The feature improves the current canonical Monitoring detail page instead of creating a second run viewer or a special governance-only route.

### D-002 — Existing truth and explanation envelopes remain canonical

`ArtifactTruthEnvelope` and `OperatorExplanationPattern` remain the semantic source of truth. The new summary layer only ranks and presents them for this one surface.

### D-003 — Affected scale stays derived from existing persisted signals

`summary_counts`, run `context`, failure summaries, and related artifact truth are sufficient inputs. The plan explicitly avoids schema changes or new count contracts.

### D-004 — Banners stay specialized; the decision zone owns the main explanation

Context, lifecycle, or restore-continuation banners may still appear, but the dominant cause and next-step explanation must live in the decision zone so the page does not say the same thing twice.

### D-005 — Shared fixtures stay opt-in

Multi-cause or zero-output scenario builders should remain local to the Monitoring suite unless a second real consumer proves they belong in a shared concern.

## Risk Assessment

| Risk | Impact | Likelihood | Mitigation |
|------|--------|------------|------------|
| The new summary duplicates existing banner copy and makes the page louder instead of calmer | High | Medium | Keep banners specialized and let the decision zone own dominant explanation text |
| Dominant-cause ranking changes arbitrarily between equivalent multi-cause runs | High | Medium | Encode one explicit ranking rule and cover it with unit tests plus one multi-cause feature test |
| Affected-scale cues drift by operation family and become inconsistent | Medium | Medium | Centralize scale mapping in the builder and reuse it across all covered run families |
| Shared fixtures or helper defaults silently hide required run context | Medium | Medium | Require explicit type, outcome, reason, and related artifact context in new scenario builders |
| Summary copy leaks inaccessible tenant or artifact hints on canonical `/admin` routes | High | Low | Keep authorization tests on related links and summary rendering together and suppress inaccessible context |

## Test Strategy

- Add one new focused feature suite for governance run summaries and keep it scoped to canonical Monitoring run detail.
- Add one narrow unit suite for dominant-cause and affected-scale derivation only if a dedicated builder is introduced.
- Reuse existing Monitoring and authorization suites for regression coverage instead of creating browser or heavy-governance breadth.
- Keep `BuildsGovernanceArtifactTruthFixtures` opt-in and add any multi-cause builder locally to the Monitoring suite first.
- Preserve DB-only rendering guarantees on canonical run detail while adjusting the visible summary hierarchy.
