TenantPilot Constitution

Core Principles

Inventory-first, Snapshots-second

  • All modules MUST operate primarily on Inventory as “last observed” state.
  • Inventory is the source of truth for what TenantPilot last observed; Microsoft Intune remains the external truth.
  • Snapshots/Backups MUST be explicit actions (manual or scheduled) and MUST remain immutable.

Read/Write Separation by Default

  • Analysis, reporting, and monitoring features MUST be read-only by default.
  • Any write/change function (restore, remediation, promotion) MUST include preview/dry-run, explicit confirmation, audit logging, and tests.
  • High-risk policy types default to preview-only restore unless explicitly enabled by a feature spec + tests.

Single Contract Path to Graph

  • All Microsoft Graph calls MUST go through GraphClientInterface.
  • Object types and endpoints MUST be modeled first in the contract registry (config/graph_contracts.php).
  • Feature code MUST NOT hardcode “quick endpoints” or bypass contracts.
  • Unknown/missing policy types MUST fail safe (preview-only / no Graph calls) rather than guessing endpoints.

Deterministic Capabilities

  • Backup/restore/risk/support flags MUST be derived deterministically from config/contracts via a Capabilities Resolver.
  • The resolver output MUST be programmatically testable (snapshot/golden tests) so config changes cannot silently break behavior.

Tenant Isolation is Non-negotiable

  • Every read/write MUST be tenant-scoped.
  • Cross-tenant views (MSP/Platform) MUST be explicit, access-checked, and aggregation-based (no ID-based shortcuts).
  • Prefer least-privilege roles/scopes; surface warnings when higher privileges are selected.
  • Tenant membership is an isolation boundary. If the actor is not entitled to the tenant scope, the system MUST respond as deny-as-not-found (404).

RBAC & UI Enforcement Standards (RBAC-UX)

RBAC Context — Planes, Roles, and Auditability

  • The platform MUST maintain two strictly separated authorization planes:
    • Tenant plane (/admin/t/{tenant}): authenticated Entra users (users), authorization is tenant-scoped.
    • Platform plane (/system): authenticated platform users (platform_users), authorization is platform-scoped.
  • Cross-plane access MUST be deny-as-not-found (404) (not 403) to avoid route enumeration.
  • Tenant role semantics MUST remain least-privilege:
    • Readonly: view-only; MUST NOT start operations and MUST NOT mutate data.
    • Operator: MAY start allowed tenant operations; MUST NOT manage credentials, settings, members, or perform destructive actions.
    • Manager: MAY manage tenant configuration and start operations; MUST NOT manage tenant memberships (Owner-only).
    • Owner: MAY manage memberships and all tenant configuration; Owner-only “danger zone” actions MUST remain Owner-only.
  • The system MUST prevent removing or demoting the last remaining Owner of a tenant.
  • All access-control relevant changes MUST write AuditLog entries with stable action IDs, and MUST be redacted (no secrets).

RBAC-UX-001 — Server-side is the source of truth

  • UI visibility / disabled state is never a security boundary.
  • Every mutating action (create/update/delete/restore/archive/force-delete), every operation start, and every credential/ config change MUST enforce authorization server-side via Gate::authorize(...) or a Policy method.
  • Any missing server-side authorization is a P0 security bug.

RBAC-UX-002 — Deny-as-not-found for non-members

  • Tenant membership (and plane membership) is an isolation boundary.
  • If the current actor is not a member of the current tenant (or otherwise not entitled to the tenant scope), the system MUST respond as 404 (deny-as-not-found) for tenant-scoped routes/actions/resources.
  • This applies to Filament resources/pages under tenant routing (/admin/t/{tenant}/...), Global Search results, and all action endpoints (Livewire calls included).

RBAC-UX-003 — Capability denial is 403 (after membership is established)

  • Within an established tenant scope, missing permissions are authorization failures.
  • If the actor is a tenant member, but lacks the required capability for an action, the server MUST fail with 403.
  • The UI may render disabled actions, but the server MUST still enforce 403 on execution.

RBAC-UX-004 — Visible vs disabled UX rule

  • For tenant members: actions SHOULD be visible but disabled when capability is missing.
  • Disabled actions MUST provide helper text explaining the missing permission.
  • For non-members: actions MUST behave as not found (404) and SHOULD NOT leak resource existence.
  • Exception: highly sensitive controls (e.g., credential rotation) MAY be hidden even for members without permission.

RBAC-UX-005 — Destructive confirmation standard

  • All destructive-like actions MUST require confirmation.
  • Delete/force-delete/archive/restore/remove membership/role downgrade/credential rotation/break-glass enter/exit MUST use ->requiresConfirmation() and SHOULD include clear warning text.
  • Confirmation is UX only; authorization still MUST be server-side.

RBAC-UX-006 — Capability registry is canonical

  • Capabilities MUST be centrally defined in a single canonical registry (constants/enum).
  • Feature code MUST reference capabilities only via the registry (no raw string literals).
  • Role → capability mapping MUST reference only registry entries.
  • CI MUST fail if unknown/unregistered capabilities are used.

RBAC-UX-007 — Global search must be tenant-safe

  • Global search results MUST be scoped to the current tenant.
  • Non-members MUST never learn about resources in other tenants (no results, no hints).
  • If a result exists but is not accessible, it MUST be treated as not found (404 semantics).

RBAC-UX-008 — Regression guards are mandatory

  • The repo MUST include RBAC regression tests asserting at least:
    • Readonly cannot mutate or start operations.
    • Operator can run allowed operations but cannot manage configuration.
    • Manager/Owner behave according to the role matrix.
  • The repo SHOULD include an automated “no ad-hoc authorization” guard that blocks new status/permission mappings sprinkled across app/Filament/**, pushing patterns into central helpers.

Operations / Run Observability Standard

  • Every long-running or operationally relevant action MUST be observable, deduplicated, and auditable via Monitoring → Operations.
  • An action MUST create/reuse a canonical OperationRun and execute asynchronously when any of the following applies:
    1. It can take > 2 seconds under normal conditions.
    2. It performs remote/external calls (e.g., Microsoft Graph).
    3. It is queued or scheduled.
    4. It is operationally relevant for troubleshooting/audit (“what ran, who started it, did it succeed, what failed?”).
  • Actions that are DB-only and typically complete in < 2 seconds MAY skip OperationRun.
  • OPS-EX-AUTH-001 — Auth Handshake Exception:
    • OIDC/SAML login handshakes MAY perform synchronous outbound HTTP (e.g., token exchange) without an OperationRun.
    • Rationale: interactive, session-critical, and not a tenant-operational “background job”.
    • Guardrail: outbound HTTP for auth handshakes is allowed only on /auth/* endpoints and MUST NOT occur on Monitoring/Operations pages.
  • If an action is security-relevant or affects operational behavior (e.g., “Ignore policy”), it MUST write an AuditLog entry including actor, tenant, action, target, before/after, and timestamp.
  • The OperationRun record is the canonical source of truth for Monitoring (status, timestamps, counts, failures), even if implemented by multiple jobs/steps (“umbrella run”).
  • “Single-row” runs MUST still use consistent counters (e.g., total=1, processed=0|1) and outcome derived from success/failure.
  • Monitoring pages MUST be DB-only at render time (no external calls).
  • Start surfaces MUST NOT perform remote work inline; they only: authorize, create/reuse run (dedupe), enqueue work, confirm + “View run”.
  • Active-run dedupe MUST be enforced at DB level (partial unique index/constraint for active states).
  • Failures MUST be stored as stable reason codes + sanitized messages; never persist secrets/tokens/PII/raw payload dumps in failures or notifications.
  • Graph calls are allowed only via explicit user interaction and only when delegated auth is present; never as a render side-effect (restore group mapping is intentionally DB-only).
  • Monitoring → Operations is reserved for OperationRun-tracked operations.
  • Scheduled/queued operations MUST use locks + idempotency (no duplicates).
  • Graph throttling and transient failures MUST be handled with backoff + jitter (e.g., 429/503).

Data Minimization & Safe Logging

  • Inventory MUST store only metadata + whitelisted meta_jsonb.
  • Payload-heavy content belongs in immutable snapshots/backup storage, not Inventory.
  • Logs MUST not contain secrets/tokens; monitoring MUST rely on run records + error codes (not log parsing).

Badge Semantics Are Centralized (BADGE-001)

  • Status-like badges (status/outcome/severity/risk/availability/boolean signals) MUST render via BadgeCatalog / BadgeRenderer.
  • Filament resources/pages/widgets/views MUST NOT introduce ad-hoc status-like badge mappings (use a BadgeDomain instead).
  • Introducing or changing a status-like value MUST include updating the relevant badge mapper and adding/updating tests for the mapping.
  • Tag/category chips (e.g., type/platform/environment) are not status-like and are not governed by BADGE-001.

Spec-First Workflow

  • For any feature that changes runtime behavior, include or update specs/<NNN>-<slug>/ with spec.md, plan.md, tasks.md, and checklists/requirements.md.
  • New work branches from dev using feat/<NNN>-<slug> (spec + code in the same PR).

Quality Gates

  • Changes MUST be programmatically tested (Pest) and run via targeted php artisan test ....
  • Run ./vendor/bin/sail bin pint --dirty before finalizing.

Governance

Scope & Compliance

  • This constitution applies across the repo. Feature specs may add stricter constraints but not weaker ones.
  • Restore semantics changes require: spec update, checklist update (if applicable), and tests proving safety.

Amendment Procedure

  • Propose changes as a PR that updates .specify/memory/constitution.md.
  • The PR MUST include a short rationale and list of impacted templates/specs.
  • Amendments MUST update Last Amended date.

Versioning Policy (SemVer)

  • PATCH: clarifications/typos/non-semantic refinements.
  • MINOR: new principle/section or materially expanded guidance.
  • MAJOR: removing/redefining principles in a backward-incompatible way.
