Oliver Kieselbach 8675e7ee06 feat(backend): provider-neutral EmailService on Mailchimp Transactional (Mandrill), replaces Resend
- EmailService + IEmailService: Mandrill messages/send via typed HttpClient with the
  Notification resilience policy; provider confined to one transport method and the
  Email:* settings (ApiKey, Endpoint, FromAddress, FromName). Resend NuGet dropped.
- open/click tracking explicitly off; sent/queued/scheduled = ok, rejected/invalid = warn
- callers (TenantApprovalService, PreviewWhitelistFunction) depend on IEmailService
- EmailServiceTests pin wire format, result semantics and fail-soft contract
- privacy page + OKF welcome-mail doc updated for the new sub-processor

Oliver Kieselbach 88cd29d3b9 backend: lifecycle completeness nets + session-scope point-read + server-side dashboard search (audit P5/P6)
P5.1 Table lifecycle buckets: TableLifecycleBucketTests classifies every
TableNames constant (offboarding buckets via reflection, per-session set from a
real DeletionManifestBuilder run, reviewed KeptByDesign list). Fixes found by
the audit: UsageMetrics offboarding wipe matched 0 rows (PK=date/RK=tenantId)
-> new SafeWipe Variant D (RowKey-anchored, verify protects the "global" row);
PlatformStats tenant partition + ScriptNameCache never wiped -> tenant-PK bucket.

P5.2 SessionsIndex field manifest: SessionIndexFieldManifest (32 always / 18
conditional / 4 primary-only) pinned bidirectionally against
BuildSessionIndexEntity and MapToSessionSummary; full rebuilds now
TableUpdateMode.Replace (heals stale conditional columns); merge sites warn on
non-manifest keys; force-path now mirrors StalledAt write + clear heals.

P5.3/P6.1 Session scope resolution: ResolveSessionScopeAsync (RequestContext)
replaces the 16-site copy-paste fallback; ResolveSessionTenantIdAsync does a
point-read on the new SessionTenantLookup table (PK=sessionId) with legacy
index-scan fallback + self-heal, replacing the cross-partition scan; the
"Count == 0 -> rescan" heuristics are gone. Write paths gate cross-tenant
resolution on IsGlobalAdmin. RecomputeTriggerGate enforces the decided
read-only semantics API-side: reanalyze/rescan now 403 for Viewer/GlobalReader/
cross-tenant tenant roles. Lookup rows ride the deletion cascade (step 22).

P6.2 Server-side dashboard search: q= on search/sessions (+global) matching
exactly the client-side searchable fields, page-backfill loop (max 10 Azure
pages/request), q bound into the pagination fingerprint; the web dashboard's
searchAll() replaces the loadAll() full-history sweep (dedupe-merge, delegated
callers keep the legacy sweep).

P6.3 Context value memoization: TenantConfigContext + Auth/Notification/
Tenant/Theme providers (cuts the externally-triggered re-render cascade).

Verified: solution build 0W/0E; Functions.Tests 4106 (+37), DecisionCore 519,
V2.Core 2206, SummaryDialog 44; tsc/eslint clean; vitest 722 (+4). Drift
detection of both new manifest tests proven by mutation.

Oliver Kieselbach 8ec5a5debd offboarding: close the un-offboard race — config freeze + fail-closed wipe guard
While a tenant offboarding is queued or draining, the TenantConfiguration
tombstone (Disabled=true, 'Offboarding in progress') is the cascade's only
auth gate. A GA lifting Disabled mid-cascade re-opened the tenant against a
wipe that was still coming: data written afterwards was destroyed, and
sessions registered after enumeration survived as orphans while their event
partitions were wiped.

Three layers close it:
- PUT config/{tenantId} returns 409 while the row is the offboarding
  tombstone — for all callers, GA included
- TenantConfigPatchService refuses patch AND revert against the tombstone
  (a revert restores a pre-offboarding snapshot with Disabled=false — the
  exact race)
- TenantOffboardingHandler re-reads the config before the destructive
  post-drain phases and fail-closes with 'unoffboard_race' when the
  tombstone is gone but the wipe has not run (last line of defense)

Shared predicate: TenantOffboardFunction.IsOffboardingTombstone.

Oliver Kieselbach 395fdd49df Transactional tenant-config writes via MCP + ConfigurationBackups safety net (#120)
* feat(backend): pre-write config backup net - every tenant/admin config save snapshots first

New ConfigurationBackups table (PK=tenantId or GlobalConfig, RK=reverse-ticks+guid,
newest-first) holds the raw stored row as EntityJson before any overwriting save of
TenantConfiguration or AdminConfiguration. Hook lives in TableConfigRepository, the
single choke point all writers funnel through - fail-soft (a backup hiccup never
breaks a save), skips row creations and noise-only changes (LastAuthClientId flips),
prunes to the newest 2 per partition. Source/reason tagging via a new
SaveTenantConfigurationAsync overload (not optional params - Moq expression trees,
CS0854); portal-put/plan/auth/app-homing/offboard call sites tagged.

Offboarding: backup partition wiped in the bulk phase (TenantPartitionTables) and by
the marker-cleanup tombstone sweep; the GlobalConfig partition never matches a tenant
GUID and survives. Table registered in TableNames.All + CriticalBackupTables.All.

Groundwork for the transactional MCP config-write flow (patch/revert endpoints follow).

* feat(backend): transactional tenant-config field patch + revert with verified writes

New GA-only surface (policy catalog: GlobalAdminOnly + RouteParam):
- PATCH config/{tenantId}/fields - field-level patch through TenantConfigPatchService:
  fresh ETag read -> field gate (deny-list incl. plan/trial, HomedAppClientId,
  auth provenance; unknown fields 400 with the name) -> patch onto a clone ->
  shared validation -> fail-CLOSED backup -> CAS replace -> fresh re-read ->
  verify that EXACTLY the intended fields changed -> automatic ETag-conditional
  rollback on drift (catches Store/Map serialization asymmetry).
- POST config/{tenantId}/revert - restore from a ConfigurationBackups snapshot
  (latest by default); snapshots current state first (revert is revertible),
  preserves plan/homing/provenance fields unless includeProtectedFields.
- GET config/{tenantId}/backups - metadata + masked diff only, never EntityJson.

Supporting changes: IConfigRepository gains GetTenantConfigurationWithEtagAsync +
TryReplaceTenantConfigurationAsync (412 -> false, no implicit backup hook);
validators moved from the PUT into shared TenantConfigValidation (PUT re-pointed,
forwarding shims keep test call sites); GET config/{tenantId} honors ?view=redacted
so a GA's MCP session never pulls clear-text secrets into model context.
Caller-tier deny-lists (TenantAdmin/DelegatedAdmin) ship now for the phase-2 flip.

* feat(mcp): tenant-config write tools - update/revert with snapshot-backed verified writes

First mutating surface on the MCP server, strictGa (real Global Admin) only:
- get_tenant_config: full config read, ALWAYS ?view=redacted (secrets never
  reach model context; pinned by config-write-tools tests)
- update_tenant_config: field-level patch via PATCH config/{tenantId}/fields;
  required reason; response = applied fields + masked diff + backupId
- list_tenant_config_backups: snapshot metadata + masked diff only
- revert_tenant_config: restore latest/named snapshot; protected fields stay
  current unless includeProtectedFields; revert is itself revertible

New MUTATING annotation + TenantGuidSchema (path-traversal guard) in shared.ts;
role-aware instructions headline (non-GA keeps the exact READ-ONLY wording);
catalog snapshot test extends GA_FULL + new CONFIG_WRITE_GA_STRICT difference
list (Global Reader/tenant/delegated see none of the four).

* test(backend): de-flake session-deletion heartbeat test - condition-gated handler instead of wall-clock window

The heartbeat test held the handler for a FIXED 350ms and expected the 50ms
heartbeat timer to tick >=3 times inside that window. On loaded CI runners the
heartbeat Task.Delay stretches disproportionately to the handler delay, the
handler completes with <3 heartbeats fired, and the awaited condition can never
become true afterwards (CI failure on PR #120). The handler now holds the
message in-flight UNTIL the test observed 3 heartbeats (with ct + own 15s
deadline as termination guards), so the assertion is reached deterministically
regardless of scheduler jitter. Verified: 12/12 local runs green, full suite green.

Oliver Kieselbach 0abccf1fe0 refactor(delegated): rename TenantTemplate -> TenantGroup across the full stack
Completes the Tenant Templates -> Tenant Groups rename down to identifiers,
tables, routes and DTOs (the earlier commit renamed only the UI labels). Done
now while the table is effectively empty; the new TenantGroups /
TenantGroupAssignments tables are auto-created on deploy, the operator re-enters
their group, and the old TenantTemplates table is dropped in Azure manually.

- Tables: TenantTemplates -> TenantGroups, TenantTemplateAssignments ->
  TenantGroupAssignments (Constants + All).
- Entities/DTOs: TenantTemplate(Entity)/TenantTemplateAssignment(Entity) ->
  TenantGroup*, property TemplateId -> GroupId.
- Repo/service/API: all *Template* methods -> *Group*; routes
  /api/global/tenant-templates -> /api/global/tenant-groups, {templateId} ->
  {groupId}; function class + file renamed; audit entity DelegatedTemplateAccess
  -> DelegatedGroupAccess; NormalizeTemplateId -> NormalizeGroupId.
- Offboarding wipe list + tests updated.
- Web: api.tenantGroups, SectionTenantGroups (file renamed), response key groups.

Scoped strictly to the feature: unrelated 'template' usages (analyze-rule
templates, EmailTemplates, interpolate-rule-template) left untouched. Backend
2538 tests green; web tsc clean + vitest 494 green.

Oliver Kieselbach 86f8fd5ace feat(delegated): tenant templates — app-internal tenant bundles for MSP delegated admins
Let a GlobalAdmin define a named Tenant Template (a bundle of tenants) and
assign a delegated-admin UPN to the template instead of to each tenant. A UPN's
effective scope = union of direct grants + every tenant in every assigned
template, resolved in DelegatedAdminService.GetScopeAsync — so middleware
enforcement, /auth/me delegatedTenantIds and MCP all inherit it unchanged.
Adding a tenant to a template grants it to all assignees at once (membership-
driven MSP management). Fully app-internal: no Entra group claim / Graph.

- Storage: TenantTemplates (PK=templateId; meta + membership rows) and
  TenantTemplateAssignments (PK=upn) tables; meta-backed existence invariant in
  both management reads AND the auth hot path (no ghost templates, no scope from
  stray rows).
- Offboarding hygiene: property-only wipe now purges TenantTemplates membership
  AND DelegatedAdmins rows for the offboarded tenant (closes a pre-existing
  orphaned-grant gap).
- Management API: GlobalAdminOnly /api/global/tenant-templates/* (8 routes);
  per-affected-tenant audit; all mutations route through the service so the
  delegated-scope cache is invalidated in lockstep; existence/membership
  invariant owned by the service (no ghost create, no false revoke audits);
  templateId normalized case-insensitively at the service boundary.
- Web: SectionTenantTemplates management UI (create/rename/delete, add/remove
  tenants, assign/unassign), triple-registered + api.ts block.

Backend 2538 tests green; web tsc clean + vitest 488 green.

Oliver Kieselbach c26b25b81b feat(backend,web): offboarding farewell-email capture + dedicated feedback table + reports tabs
- Persist tenant Preview-Notification-Email on OffboardingHistory row at Phase 1 so it
  survives Phase 2 wipe; ResendEmailService.SendAsync wired but disarmed by a const-false
  arm-flag with a [DRAFT] placeholder template — explicit flip required to ship.
- Move user feedback storage out of PreviewConfig discriminator into a dedicated Feedback
  table (PK=InApp / Offboarding) that is NOT in any tenant-offboarding wipe list — feedback
  from departing tenants is exactly the signal we want to keep. New IFeedbackRepository +
  TableFeedbackRepository; FeedbackFunction migrated; (PreviewConfig, "Feedback")
  removed from TenantOffboardingHandler.DiscriminatorTables.
- POST /api/tenants/{tenantId}/offboard/feedback collects a free-form farewell comment
  during the drain-barrier countdown (marker-gated, fail-soft OpsEvent emit). Reports >
  User Feedback page gains an Offboarding-Feedback sub-tab next to In-App Feedback.
- OffboardingFeedbackReceived OpsEventType registered (info-severity) + catalog entry
  in OpsAlertRulesSection so admins can wire Telegram in two clicks.

Oliver Kieselbach 206388da99 feat(backend,web): tenant offboarding async cascade with customs archive
Replace synchronous DeleteAllTenantDataAsync with a queued async cascade
that wipes all 24 tenant-scoped tables safely, archives custom rules,
and survives crashes at every step.

Phase 1 (TenantOffboardFunction, ~200ms sync):
  - Write History / ByTenantPointer / Marker rows (OffboardingAudit table)
  - Flip TenantConfiguration.Disabled=true (the active auth gate)
  - Enqueue with 6 min visibility-delay (cache-drain barrier =
    TenantConfigurationService.CacheDuration 5 min + 1 min safety)
  - Return 202 with EarliestProcessingAt for the UI countdown

Phase 2 (TenantOffboardingWorker + Handler, async after drain):
  - Enumerate sessions, per-session cascade-enqueue, persist
    Expectations blob (separate offboarding-state container)
  - Drain probe against per-session progress blobs; self re-enqueue
    up to 60x at 2 min visibility-delay
  - 2.D-archive: GatherRules / AnalyzeRules / ImeLogPatterns moved
    to TenantOffboardingCustomsArchive table (3-iter cap + verify)
  - 2.D-wipe: SafeWipe over all tenant tables (4 variants: exact-PK,
    composite-PK range, discriminator+TenantId, property-only) with
    fetch+verify+delete pattern + SafeWipeVerificationException
  - 2.E: blob-prefix wipe deletion-manifests/{tenantId}/
  - 2.D-pass-2: re-wipe AuditLogs (defense-in-depth)
  - 2.G: side-effects FIRST (Marker, Pointer, blob, audit, OpsEvent)
    then History=Completed LAST (DrainCompletedAt as resume anchor)
  - 2.F-final: delete TenantConfiguration row LAST so self-service
    re-onboarding (next /api/auth/me auto-creates default) works

Defense-in-depth:
  - OffboardingMarkerCleanupFunction (2h timer): sweeps Completed
    markers after 15 min grace, conditional TenantConfiguration sweep
    (only when row is still the offboarding tombstone — preserves
    user-driven self-service re-onboards)
  - Worker poison path: durable Failed state MUST land before queue
    moves; transient failure leaves message visible for retry
  - SessionDeletionHandler reorder: Audit + SignalR notify BEFORE
    CompletedAt write so the drain predicate is correct

Web UI:
  - /settings danger zone: typed "OFFBOARD" confirmation dialog,
    post-202 drain-barrier banner with minute-based countdown, hint
    "you can sign out and close this tab — deletion runs in
    background", silent auto-logout when countdown elapses
  - /admin/customs-archive (GA only): list runs + inspect entries +
    typed "DELETE" confirmation modal for run/entry deletion
  - OpsAlertRulesSection: TenantOffboardingFailed event registered
  - lib/api.ts: shared CustomsArchive* response types

Tests: 100+ new tests covering drain contract, handler ordering,
worker poison path, ETag-CAS, SafeWipe variants, OffboardingFilters
prefix-bleed safety, MarkerCleanup conditional sweep, Bootstrap
auth-disabled-tenant gate.
