## Constitution Check

*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*

- Inventory-first: clarify what is “last observed” vs snapshots/backups
- Read/write separation: any writes require preview + confirmation + audit + tests
- Graph contract path: Graph calls only via `GraphClientInterface` + `config/graph_contracts.php`
- Deterministic capabilities: capability derivation is testable (snapshot/golden tests)
- RBAC-UX: two planes (/admin vs /system) remain separated; cross-plane is 404; tenant-context routes (/admin/t/{tenant}/...) are tenant-scoped; canonical workspace-context routes under /admin remain tenant-safe; non-member tenant/workspace access is 404; member-but-missing-capability is 403; authorization checks use Gates/Policies + capability registries (no raw strings, no role-string checks)
- Workspace isolation: non-member workspace access is 404; tenant-plane routes require an established workspace context; workspace context switching is separate from Filament Tenancy
- RBAC-UX: destructive-like actions require `->requiresConfirmation()` and clear warning text
- RBAC-UX: global search is tenant-scoped; non-members get no hints; inaccessible results are treated as not found (404 semantics)
- Tenant isolation: all reads/writes tenant-scoped; cross-tenant views are explicit and access-checked
- Run observability: long-running/remote/queued work creates/reuses `OperationRun`; start surfaces enqueue-only; Monitoring is DB-only; DB-only <2s actions may skip runs but security-relevant ones still audit-log; auth handshake exception OPS-EX-AUTH-001 allows synchronous outbound HTTP on `/auth/*` without `OperationRun`
- Ops-UX 3-surface feedback: if `OperationRun` is used, feedback is exactly toast intent-only + progress surfaces + exactly-once terminal `OperationRunCompleted` (initiator-only); no queued/running DB notifications
- Ops-UX lifecycle: `OperationRun.status` / `OperationRun.outcome` transitions are service-owned (only via `OperationRunService`); context-only updates allowed outside
- Ops-UX summary counts: `summary_counts` keys come from `OperationSummaryKeys::all()` and values are flat numeric-only
- Ops-UX guards: CI has regression guards that fail with actionable output (file + snippet) when these patterns regress
- Ops-UX system runs: initiator-null runs emit no terminal DB notification; audit remains via Monitoring; tenant-wide alerting goes through Alerts (not OperationRun notifications)
- Automation: queued/scheduled ops use locks + idempotency; handle 429/503 with backoff+jitter
- Data minimization: Inventory stores metadata + whitelisted meta; logs contain no secrets/tokens
- Proportionality (PROP-001): any new structure, layer, persisted truth, or semantic machinery is justified by current release truth, current operator workflow, and why a narrower solution is insufficient
- No premature abstraction (ABSTR-001): no new factories, registries, resolvers, strategy systems, interfaces, type registries, or orchestration pipelines before at least 2 real concrete cases exist, unless security, tenant isolation, auditability, compliance evidence, or queue correctness require it now
- Persisted truth (PERSIST-001): new tables/entities/artifacts represent independent product truth or lifecycle; convenience projections and UI helpers stay derived
- Behavioral state (STATE-001): new states/statuses/reason codes change behavior, routing, permissions, lifecycle, audit, retention, or retry handling; presentation-only distinctions stay derived
- UI semantics (UI-SEM-001): avoid turning badges, explanation text, trust/confidence labels, or detail summaries into mandatory interpretation frameworks; prefer direct domain-to-UI mapping
- V1 explicitness / few layers (V1-EXP-001, LAYER-001): prefer direct implementation, local mappings, and small helpers; any new layer replaces an old one or proves the old one cannot serve
- Spec discipline / bloat check (SPEC-DISC-001, BLOAT-001): related semantic changes are grouped coherently, and any new enum, DTO/presenter, persisted entity, interface/registry/resolver, or taxonomy includes a proportionality review covering operator problem, insufficiency, narrowness, ownership cost, rejected alternative, and whether it is current-release truth
- Badge semantics (BADGE-001): status-like badges use `BadgeCatalog` / `BadgeRenderer`; no ad-hoc mappings; new values include tests
- Filament-native UI (UI-FIL-001): admin/operator surfaces use native Filament components or shared primitives first; no ad-hoc status UI, local semantic color/border decisions, or hand-built replacements when native/shared semantics exist; any exception is explicitly justified
- UI/UX surface taxonomy (UI-CONST-001 / UI-SURF-001): every changed operator-facing surface is classified as exactly one allowed surface type; ad-hoc interaction models are forbidden
- UI/UX inspect model (UI-HARD-001): each list surface has exactly one primary inspect/open model; redundant View beside row click or identifier click is forbidden; edit-as-inspect is limited to Config-lite resources
- UI/UX action hierarchy (UI-HARD-001 / UI-EX-001): standard CRUD and Registry rows expose at most one inline safe shortcut; destructive actions are grouped or in the detail header; queue exceptions are catalogued, justified, and tested
- UI/UX scope, truth, and naming (UI-HARD-001 / UI-NAMING-001 / OPSURF-001): scope signals are truthful, canonical nouns stay stable across shells, critical operational truth is default-visible, and standard lists remain scanable
- UI/UX placeholder ban (UI-HARD-001): empty `ActionGroup` / `BulkActionGroup` placeholders and declaration-only UI conformance are forbidden
- UI naming (UI-NAMING-001): operator-facing labels use `Verb + Object`; scope (`Workspace`, `Tenant`) is never the primary action label; source/domain is secondary unless disambiguation is required; runs/toasts/audit prose use the same domain vocabulary; implementation-first terms do not appear in primary operator UI
- Operator surfaces (OPSURF-001): `/admin` defaults are operator-first; default-visible content avoids raw implementation detail; diagnostics are explicitly revealed secondarily
- Operator surfaces (OPSURF-001): execution outcome, data completeness, governance result, and lifecycle/readiness are modeled as distinct status dimensions when all apply; they are not collapsed into one ambiguous status
- Operator surfaces (OPSURF-001): every mutating action communicates whether it changes TenantPilot only, the Microsoft tenant, or simulation only before execution
- Operator surfaces (OPSURF-001): dangerous actions follow configuration → safety checks/simulation → preview → hard confirmation where required → execute, unless a spec documents an explicit exemption and replacement safeguards
- Operator surfaces (OPSURF-001): workspace and tenant context remain explicit in navigation, actions, and page semantics; tenant surfaces do not silently expose workspace-wide actions
- Operator surfaces (OPSURF-001): each new or materially refactored operator-facing page defines a page contract covering persona, surface type, operator question, default-visible info, diagnostics-only info, status dimensions, mutation scope, primary actions, and dangerous actions
- Filament UI Action Surface Contract: for any new/modified Filament Resource/RelationManager/Page, define Header/Row/Bulk/Empty-State actions, ensure every List/Table has a surface-appropriate inspect affordance, remove redundant View when row click or identifier click already opens the same destination, keep standard CRUD/Registry rows to inspect plus at most one inline safe shortcut, group or relocate the rest to “More” or detail header, forbid empty bulk/overflow groups, require confirmations for destructive actions, write audit logs for mutations, enforce RBAC via central helpers (non-member 404, member missing capability 403), and ensure CI blocks merges if the contract is violated or not explicitly exempted
- Filament UI UX-001 (Layout & IA): Create/Edit uses Main/Aside (3-col grid, Main=columnSpan(2), Aside=columnSpan(1)); all fields inside Sections/Cards (no naked inputs); View uses Infolists (not disabled edit forms); status badges use BADGE-001; empty states have specific title + explanation + 1 CTA; max 1 primary + 1 secondary header action; tables provide search/sort/filters for core dimensions; shared layout builders preferred for consistency

## Complexity Tracking

> **Fill when Constitution Check has violations that must be justified OR when BLOAT-001 is triggered by new persistence, abstractions, states, or semantic frameworks.**

| Violation | Why Needed | Simpler Alternative Rejected Because |
|-----------|------------|-------------------------------------|
| [e.g., 4th project] | [current need] | [why 3 projects insufficient] |
| [e.g., Repository pattern] | [specific problem] | [why direct DB access insufficient] |

## Proportionality Review

> **Fill when the feature introduces a new enum/status family, DTO/presenter/envelope, persisted entity/table/artifact, interface/contract/registry/resolver, taxonomy/classification system, or cross-domain UI framework.**

- **Current operator problem**: [What present-day workflow or risk requires this?]
- **Existing structure is insufficient because**: [Why the current code cannot serve safely or clearly]
- **Narrowest correct implementation**: [Why this shape is the smallest viable one]
- **Ownership cost created**: [Maintenance, testing, cognitive load, migration, or review burden]
- **Alternative intentionally rejected**: [Simpler option and why it failed]
- **Release truth**: [Current-release truth or future-release preparation]
