Neues Modell Dashboard (D-01/D-02/D-09): position statt Standard-Feld,
kein Unique auf (userId, position) - Umsortieren schreibt spaeter alle
Positionen einer Transaktion neu. WidgetInstance/DashboardLayout haengen
jetzt am Reiter statt am Benutzer (DashboardLayout.dashboardId @unique
ersetzt userId @unique).
Migration 20260923120000_dashboard_tabs: Zeilenschutz mit Mandant- UND
Benutzerdimension (Form 20260911120000/20260921120000), Bestands-
uebernahme fuer jeden Benutzer mit Kacheln oder Anordnung VOR den
Fremdschluesseln (D-03) - gemessen: 0 Kacheln/Anordnungen ohne Reiter,
genau 2 Reiter auf Position 0.
dashboard.service.ts: listDashboards() (Transaktionssperre gegen
doppelte Erstanlage, T-AD9-07), Riegel assertOwnedDashboard() (fail-
closed gegen fremde Reiter, T-AD9-01/02/03) - getLayout/saveLayout/
getWidgets/addWidget laufen jetzt ueber dashboardId statt userId.
GET /dashboard/tabs neu; die vier bestehenden Wege reichen die Reiter-
Kennung durch. Verhalten fuer den Benutzer unveraendert (ein Reiter,
wie bisher) - Task 2 ergaenzt Anlegen/Umbenennen/Loeschen/Umsortieren.
dashboard.service.spec.ts: 43 Tests (31 alte unveraendert + 12 neue fuer
Reiter-Anlage, -Reihenfolge und den Fremdreiter-Riegel bei allen vier
Wegen). Zugriffsklassifikation nachgerechnet: 75 Paare (+1), Bereich
dashboard 21->24 gebunden.

- Bytes liegen unter user-files/dashboard-images/<userId>/<id>.<ext>, die
Zeile haelt nur noch storagePath (Muster User.avatarPath)
- Dateiname immer servergeneriert: UUID der Zeile + Endung aus dem
ERKANNTEN Mime-Typ, originalName kommt in keinem Pfad vor (T-HK4-01)
- Migration 20260922120000: storagePath dazu, data wird NULLbar, kein DROP
(zweistufig, T-HK4-03); system_read_policy fuer den Umzug
- onApplicationBootstrap zieht Altbestand automatisch um: systemgebunden
lesen, je Zeile mandantengebunden schreiben (Muster DKV-Planer)
- Upload nimmt die Zeile bei fehlgeschlagenem Schreiben zurueck, Loeschen
entfernt die Datei mit, fehlende Datei -> 404 (T-HK4-04)
- 11 neue Dienst-Tests gegen ein echtes Temp-Verzeichnis (kein fs-Mock)
- Zugriffsklassifikation: Stand system-gebunden, Zahlen nachgemessen

- Prisma-Modell DashboardImage (bytea) mit Migration 20260921120000: Tabelle,
Indizes, RLS ENABLE/FORCE und tenant_isolation_policy mit Benutzerdimension
- dashboard-image-rules.ts: detectImageMime ueber Magic Bytes (PNG/JPEG/GIF/
WebP), Grenzen 5 MiB je Datei und 30 je Benutzer
- DashboardImagesService: list/upload/getBytes/remove, je Methode
forTenant(prisma, tenantId, userId); Besitz = Mandant UND Benutzer, sonst 404
- DashboardImagesController unter dashboard/images: GET, POST (FileInterceptor
image, 5 MiB, eine Datei), GET :id mit Content-Type aus dem erkannten Typ,
Cache-Control private, nosniff, Content-Disposition inline ohne Dateinamen,
CSP sandbox; DELETE :id
- CreateWidgetDto kennt 'picture-frame'
- Klassifikationsdokument: neues Paar dashboard-images.service.ts/
dashboardImage; Bereichs- und Summenzeilen nachgemessen (dashboard 12->18,
settings 3->4 und bug-reports waren in der Summe nie mitgezaehlt)
- Befund: Prisma-Bytes verlangt Uint8Array<ArrayBuffer>, multers Buffer wird
ohne Zusicherung abgelehnt - Kopie per new Uint8Array(buffer) statt Cast

- User.email auf optional gestellt (Migration geschrieben, NICHT
ausgefuehrt); Eindeutigkeitsindex unangetastet, NULL bleibt in Postgres
je verschieden
- Neuer Kollisionsentscheider (resolveEmailForWrite) in ldap.service.ts:
eine bereits vergebene Adresse wird nie umgehaengt (T-Q3-01) — das
zuerst angelegte Konto behaelt sie, jedes weitere Konto entsteht ohne
Adresse (gesperrte Nutzerentscheidung 2026-09-09, WINDOWS #15)
- Entscheider in upsertMappedUser (Sync) UND importUsersByDn (Handimport)
verdrahtet, damit der zweite Anlageweg nicht als Luecke bestehen bleibt
- LdapSyncResult um emailConflicts/skippedNoLogin/entryFailures erweitert;
rohe ORM-Ausnahmetexte gehen nur noch an logger.error, nie in den
Bericht (T-Q3-02)
- UserService.create nimmt die Adresse optional entgegen; Tender-Digest
und Instant-Alert ueberspringen Empfaenger ohne Adresse (continue)
- Fuenf neue Testfaelle vorab gegen den unveraenderten Bestand rot
gelaufen (erwartete Ursachen bestaetigt); 651/651 API-Tests gruen,
prisma validate und type-check sauber

- TenderRssFeedSource.userId/tenantId (nullable): null = platform-wide
(admin-managed, includes the existing service.bund.de default),
set = personal feed owned by exactly one user
- Migration replaces url @unique with @@unique([userId, url]) — two
users can now follow the same address independently; existing rows
keep an empty owner (platform-wide, unchanged behavior)
- Service: listForUser/createForUser/createPlatform replace list/create
- Controller: GET/POST /rss-feeds move from @Roles(ADMIN,SUPER_ADMIN) to
@UseModule('tender-radar'); POST with scope:'platform' still requires
ADMIN/SUPER_ADMIN, checked inline (T-17-08)
- tenders.module.ts seed switched from upsert-on-url to find-then-create
(Rule 3, pulled forward from Task 3): the new compound unique index
requires a non-null userId in Prisma's generated type, so a
platform-wide row can no longer be addressed via upsert
- Files modified: apps/api/prisma/schema.prisma, apps/api/prisma/migrations/20260812110000_tender_rss_feed_owner/migration.sql, apps/api/src/tenders/tender-rss-feed.service.ts, apps/api/src/tenders/dto/tender-rss-feed.dto.ts, apps/api/src/tenders/tenders.controller.ts, apps/api/src/tenders/tenders.module.ts, apps/api/src/tenders/tender-rss-feed.service.spec.ts, apps/api/src/tenders/tenders.controller.spec.ts
Alert-Postfach gehoert jetzt dem einzelnen Nutzer (userId @unique) statt
dem Mandanten (D-01) — ein zweiter Kollege desselben Mandanten kann sein
eigenes Postfach anbinden. tenantId bleibt denormalisiert (SMTP-Aufloesung,
Herkunftsmarkierung), wird auf create UND update mitgeschrieben.
- Handgeschriebene Migration (prisma migrate dev verweigert die
nicht-interaktive Shell): befuellt Bestandszeilen mit dem aeltesten
aktiven Administrator ihres Mandanten, entfernt verwaiste Zeilen ohne
Administrator, ersetzt die tenantId-Eindeutigkeit durch userId.
Lokal getestet (0 Bestandszeilen lokal und auf alpha — Zaehlung im
Task-1-Checkpoint), Index-Ergebnis verifiziert.
- TenderEmailConfigService.getConfigForApi/saveConfig auf userId als
Schluessel umgestellt; saveConfig nimmt {userId, tenantId}.
- TendersController: email-config-Routen von @Roles(ADMIN,SUPER_ADMIN)
auf @UseModule('tender-radar') umgestellt (Postfach ist jetzt
Nutzereinstellung); Route-Reihenfolge vor @Get(':id') unveraendert.
- Neue Seite /modules/tender-radar/my-sources ("Meine Quellen") mit dem
unveraenderten EmailAlertConfigForm; Hinweistext benennt D-05 (Tender
bleibt plattform-global — nur wer Quellen einspeist aendert sich).
- tenders.controller.spec.ts an neue Service-Signatur angepasst (Rule 3,
nicht im Plan gelistet, aber zum Kompilieren/Bestehen erforderlich).

The LDAP bind password was the only credential still stored in clear text.
CalendarSource, SmtpConfig, DkvModuleConfig and TenderEmailConfig have been
AES-256-GCM encrypted for a while; LDAP simply predated the encryption service
and was never brought along.
Hashing is not an option here: Tessera has to replay this password to bind
against the directory, so it must stay recoverable. Encryption at rest covers
the case a hash cannot help with either way -- a database dump or backup
leaving the host without the key, which lives in the application environment.
It does not protect against a compromised host, and does not pretend to.
Reuses CalendarCryptoService, the same provider SettingsModule, DkvModule and
TendersModule already inject, rather than introducing a second crypto path.
The name is a historical accident and is noted as such in LdapModule; renaming
it touches five modules and belongs in its own change.
Decryption sits in getConfig()/getAllActiveConfigs(), the two methods every
consumer already goes through, so callers keep reading a plain `bindPassword`
and the controller keeps masking it to '********' in responses.
The migration only renames the column -- SQL cannot encrypt, since the key is
not in the database. An idempotent bootstrap backfill encrypts rows written
before this change, and until it has run the read path passes a legacy
plaintext value through unchanged so the sync does not break in that window.
A failed decrypt throws rather than returning null: a wrong key must not read
as "no password configured" and silently turn an authenticated bind into an
anonymous one.

Task 1 checkpoint resolved: approve-both, granted 2026-08-06 by the
project owner (D-04 one-way schema extension: Group.internalName +
Group.ldapObjectGuid, both nullable, one versioned migration).
Adds the Phase 16 tracer slice through every layer:
- Prisma schema: Group.internalName, Group.ldapObjectGuid,
@@unique([tenantId, ldapObjectGuid]) (Prisma client regenerated;
the versioned migration itself is Task 3, separately blocking).
- LdapService: listGroups() now reads objectGUID via
explicitBufferAttributes and flags alreadyImported per tenant;
new importGroupsByDn() creates a Group per checked DN with
name/ldapDn/ldapObjectGuid, reject-with-report on name collision
(P2002 on name -> nameCollisions, P2002 on ldapObjectGuid ->
skipped), never aborts the batch on one DN's error; new static
escapeLdapFilterBuffer() for Plan 16-03's later existence sweep.
- DTO/controller: ImportGroupsDto, POST /ldap/groups/import
(ADMIN/SUPER_ADMIN), listGroups route now tenant-scoped.
- Frontend: new "AD-Gruppen importieren" section in /admin/ldap,
own discovery/import handlers with a visible error state
(Owner decision 2026-08-06 — no silent catch{} for these two
handlers), i18n keys in de.json/en.json.
- Tests: 8 new cases covering the full <behavior> list plus
listGroups sort order and alreadyImported.
Flagged assumption (RESEARCH.md A1/A2): objectGUID rename-stability
and the binary filter syntax are unverified against a real AD —
this plan only WRITES the GUID, Plan 16-03 reads it back live.
- Group/GroupMembership/ModuleGrant models plus MembershipSource enum
(D-05), placed under TenantModuleActivation with German block comment
- Hand-SQL appended to the generated migration: partial unique index for
one default group per tenant (D-13), CHECK num_nonnulls xor-constraint
plus two partial unique indexes for ModuleGrant (D-04), and the D-06
backfill (Group -> GroupMembership -> ModuleGrant, each INSERT guarded
by WHERE NOT EXISTS for idempotent re-runs on `prisma migrate deploy`)
- apps/api/src/groups/migration-sql.spec.ts verifies the hand-SQL by
reading migration.sql directly, no DB required
- Verified against the local DB: default-group count matches tenant
count, membership/grant counts match existing users/active
activations, and the XOR constraint rejects a group+user-less insert
Prisma: new TenderEmailConfig model (per-tenant, tenantId @unique, mirrors
DkvModuleConfig) + Tender.ownerTenantId nullable column + index (D-13:
null = global/platform-wide, unchanged for all existing rows and every
public source; set = visible only to that tenant). Migration
20260723113917_tender_email_config_owner_tenant_id applied locally.
TenderEmailConfigService: safe-select admin CRUD (GET never returns the
password, only hasPassword — T-07-12) with DkvService's encrypt-preserve-
empty semantics, via CalendarCryptoService (AES-256-GCM).
RawTenderRecord/NormalizedTenderFields gain optional ownerTenantId,
threaded through TenderNormalizerService.assemble() unchanged.
TenderDedupService's CREATE branch writes ownerTenantId (defaulting to
null); the UPDATE branch deliberately never references it, so a tender
later also seen on a public source is never retroactively hidden.
EmailAlertAdapter.fetchTenders() now does the real per-tenant fan-out:
findMany({isActive:true}) across ALL tenants (deliberate, documented
cross-tenant platform-scheduler read, never forTenant()/RLS), decrypts
each tenant's credentials, picks imap/exchange provider, and tags every
extracted candidate with ownerTenantId — catch-per-tenant so one broken
mailbox never blocks the others.
tenders.module.ts: imports CalendarModule/InboxModule, registers
EmailAlertAdapter + TenderEmailConfigService, seeds an 'email-alert'
TenderSourcePollConfig row (pollGranularity='tick', isActive=false —
no default mailbox to activate yet, D-02 framework-ready stance).

Global admin-managed RSS feed list (TenderRssFeedSource, D-08/D-14) with
a save-time hostname/SSRF guard (TenderRssFeedSourceService) — RSS feed
URLs are runtime admin input, so the code-level SourceRegistry denylist
gate does not cover them; a separate check rejects DENYLISTED_PORTALS
hostnames, non-http(s) schemes, and private/loopback hosts.
Adds TenderSourcePollConfig.pollGranularity ('day' | 'tick', D-15):
pollDueSources() branches per source — 'day' sources keep the existing
lastIngestedDay gate byte-unchanged, 'tick' sources (rss) fetch on every
active scheduler tick regardless of lastIngestedDay, since the day-cursor
gate was built for a genuine daily batch-export API and would otherwise
silently cap RSS to one fetch per calendar day.
Wires RssAdapter.fetchTenders() to fan out over active feed rows (native
fetch + AbortController 15s + response-size ceiling, catch-per-feed),
registers it in tenders.module.ts, and seeds the 'rss' poll config
active with pollGranularity='tick' plus a default-active service.bund.de
feed row (subreport-elvis has no single canonical URL — zero rows seeded,
admin adds relevant municipality feeds).
Migration applied locally per project convention (host -> container IP).

Additive schema change (SCHEMA-03/D-03/D-04): new model TenderSource
(1:n Tender, @@unique[sourcePortal, sourceNoticeId], onDelete Cascade)
and a nullable Tender.fingerprint column + index. dedupKey stays
unchanged as the SCHEMA-02 upsert target.
Migration 20260723120000_add_tender_source applies in strict order
(Pitfall 5): table+column create, then one TenderSource row per
pre-existing Tender via SQL INSERT/SELECT, then the unique constraint.
Applied locally against the tessera dev DB (container IP, no host
port) — verified via psql: TenderSource count == Tender count == 2851.
backfill-tender-source.ts is a one-time script that computes
Tender.fingerprint via the Task-1 tenderFingerprint() function
(Decimal->number conversion for estimatedValue, T-13-01-03) — run via
the compiled dist/ output (source uses standard extensionless TS
imports for tsc compatibility). Confirmed: 2851/2851 rows backfilled,
idempotent re-run verified.

Add a per-tenant "Skip TLS certificate verification" toggle to the LDAP
admin page so admins can connect to an AD whose ldaps:// certificate is
signed by an internal/self-signed CA (Node error: "unable to verify the
first certificate"). When enabled, ldapts is given
tlsOptions.rejectUnauthorized=false; the flag is ignored for plain ldap://
(no TLS). Defaults to full verification.
New Boolean column LdapConfig.tlsRejectUnauthorized (@default(true)) +
migration; wired through DTOs, config service, all Client creations
(test/groups/user-search/import/sync) and the test-connection endpoint. UI
checkbox with an insecure-network warning (de/en). 3 new service specs;
API 218 green, web 131 green, both apps tsc clean.

via cpv-catalog.ts's divisionOf() — replaces exact-match cpvCodes
comparison with a typesafe, GIN-indexable hasSome target (FILTER-03,
Pitfall 2). Backfill migration 20260721150000_tender_cpv_divisions_backfill

(741 rows carry division '45' — Bauarbeiten); idempotent (second run:
UPDATE 0, ADD COLUMN IF NOT EXISTS / CREATE INDEX IF NOT EXISTS both skip
cleanly). Applied via docker exec psql + `prisma migrate resolve
--applied` + `prisma generate` against the local dev DB only — no
Docker deploy on the test server.

Replace the Phase-10-deferred `bundesland = null` assignment with
bundeslandFromRegion(region) so new ingests are Bundesland-filterable
immediately. Add @@index([bundesland]) for filter performance. New
handwritten migration 20260721140000_tender_bundesland_backfill backfills
the ~1671 pre-existing rows (idempotent UPDATE, only where bundesland IS
NULL AND region IS NOT NULL) — applied locally via
`docker exec tessera-ctl-db-1 psql`, resolved as applied in
_prisma_migrations, and prisma generate re-run.
Verified on the local dev DB: 933/1671 rows now have bundesland set
across all 16 Länder (738 remain NULL where region itself is NULL).

Add a per-username denylist so individual accounts (service accounts like
administrator, krbtgt, guest, ldap$) can be excluded from LDAP sync,
independent of the group/OU include-filter which only scopes the search.
- schema: LdapConfig.userExcludeList String[] (+ migration)
- sync: skip excluded usernames (case-insensitive) before recording the DN,
so an already-imported user added to the list gets deactivated next sync
- DTO / config service / controller / scheduler: thread userExcludeList through
- web: exclude-list admin UI section (add/remove/save) + de/en translations
- tests: 3 specs covering empty list, case-insensitive skip, deactivation

bindDn and bindPassword are now optional on LdapConfig (nullable
migration) and throughout the DTOs/service/client -- an admin can
leave both blank to connect to directories that permit anonymous
read access. LdapService.bind() falls back to an RFC 4513 anonymous
bind (empty DN + empty password) whenever either field is missing,
shared across testConnection, listGroups, and syncUsersForTenant.
Frontend: removed the required attribute from Bind-DN/Bind-Passwort,
added a placeholder hint ("leer = anonymous bind"), and the
"Verbindung testen" button now only needs a Server-URL to enable
(not bindDn+bindPassword). Config responses now return bindPassword
as null (not a misleading "********") when no password is set.
Verified locally: submitted only a Server-URL with both bind fields
empty and confirmed the request reached the anonymous-bind code path
(DNS failure for the unreachable test host, not a validation error).
