 ## 12. Änderungsprotokoll
 
+2026-09-24 (Phase 7, Workspace-Ladezeit): Der erste Timeslot-Load wurde lokal mit autorisiertem Dummy gemessen und beschleunigt. (1) Data Hub laedt den kompletten Workspace fuer seine Donuts; Open lud denselben Scope erneut. Die Ladung wird jetzt genau einmal an das naechste Open desselben normalisierten Projekt-/Run-/Assessment-Scopes uebergeben, nur wenn sie hoechstens 60 s alt ist und seit Beginn keine mutierende API-Anfrage startete oder endete; sonst wird frisch geladen. (2) Mit explizitem Assessment-Scope laeuft die GPO-Kette (Observations, Evaluations/Overview, Baseline-Analysen) parallel zum Scannermodell. (3) Baseline-Analysen (je 2-4 MB) laden mit hoechstens drei gleichzeitigen Anfragen statt strikt sequenziell; jede Baseline schreibt nur eigene Result-IDs, Fehler bleiben je Baseline markiert. (4) Zeilenanalyse: Kopfzeilenordnung und -merkmale einmal je Kopfzeilenliste (Identitaets-Cache mit Kopie, erkennt Mutation), jede Zelle einmal bereinigt, per-Zelle toLowerCase() statt toLocaleLowerCase(de-DE) (fuer alle 1.112.064 Codepoints in Browser und Node identisch; Deutsch hat keine sprachspezifischen Mappings). Ausgabe bytegleich verifiziert (Browser-Loader-Fingerprint unveraendert, 53-MB-Sheet-Serialisierung alt/neu identisch); Record-IDs und Reviews bleiben stabil, kein Reimport. Beobachtungen: Open nach Data-Hub-Auswahl 8,6 s -> 0,7 s; Tenant-Klick bis Client Info (kalt) ~5,2 s statt Data-Hub-Load plus 8,6 s; GPO-Anfuegen in Node 643-653 -> 423-461 ms. Offen: verbleibende ~1,9 s Main-Thread-Block beim Datasetaufbau (GPO-Zeilen werden fuer GPO- und Aggregatblatt analysiert); ein Worker waere eine eigene Architekturentscheidung. Tests: synthetische Nebenlaeufigkeits-, Handoff-, Cache- und Aequivalenzregressionen; Gesamtlauf 1.642 bestanden/16 uebersprungen, beide Builds erfolgreich.
+
+2026-09-24 (Phase 13D, AI-Uebersicht Ladezeit): Der GET der AI-Uebersicht baut fuer die Stale-Pruefung die komplette Timeslot-Eingabe; mit 500er-Seiten projizierte das Repository alle Ergebnisse neunmal (lokal gemessen ~5,5 s, Beobachtung). Die AI-Eingabe liest jetzt mit der Repository-Maximalseite von 10.000 (~0,9 s beobachtet); Konsistenzpruefung und Paging fuer groessere Timeslots bleiben. Client Info wird beim Bereichswechsel entladen; die letzte Antwort je Projekt-/Timeslot-Scope liegt in einem auf acht Scopes begrenzten Modulcache, wird beim Wiedereintritt sofort gezeigt und bei jedem Mount ohne Ladeanzeige revalidiert; Antworten und Generierungsstarts ersetzen den Eintrag. Synthetischer Remount-Test (schlaegt ohne Cache fehl) ergaenzt, Seitengroessen-Erwartung angepasst; Gesamtlauf 1.631 bestanden/16 uebersprungen, beide Builds erfolgreich. Offen: erster Workspace-Load ~8,6 s (Netzwerk-Wasserfall inkl. elf sequenzieller Baseline-Analysen plus ~3,5 s Main-Thread).
+
+2026-09-24 (Phase 13D, AI-Uebersicht): Environment-Fakten gingen bei gechunkter Generierung verloren, weil sie nur im letzten Chunk lagen und die Konsolidierung nur Teilanalysen erhielt; ein Findings-only-Chunk meldete fehlende Fakten und die Konsolidierung uebernahm das. Jeder Chunk und jeder Konsolidierungsaufruf erhaelt jetzt Summary und vollstaendige environmentFacts als gemeinsamen Kontext; nur Findings und Not-run-Checks werden aufgeteilt. Eingabeinhalt und -hash bleiben unveraendert, bestehende Laeufe gelten daher nicht als stale und muessen manuell neu erzeugt werden. Synthetischer Regressionstest fuer Chunk- und Konsolidierungspayload ergaenzt; Gesamtlauf 1.630 bestanden/16 uebersprungen, beide Builds erfolgreich. Result-DB-JSON-Export folgt weiterhin den aktiven Filtern, unter dem Deviation-Standard also ohne Environment-Fakten. Kein Reimport, keine Migration.
+
+2026-09-24 (Phase 7/13C mit Phase 12/13B): Defender-for-IoT-Findingnamen nach dem Merge von `83284c2` wiederhergestellt. Die Source-Rule-ID-Projektion benennt ein natives ID-Feld nicht mehr um, wenn es zugleich der Findingtitel ist (Defender `CVE`), und ergaenzt die ID stattdessen; Disclosure Policy 2.6.0 gibt fuer Defender ausschliesslich die oeffentliche CVE-ID als Rule ID und Titel frei. Synthetische Work-/Result-DB-Regression, keine Migration, kein Reimport.
+
 2026-09-23 (Phase 13D): Token-geschuetzten ISO-Doppel-PDF-Upload, privaten Korpusstand, begrenzten Parserworker, Embeddingfortschritt, Indexvollstaendigkeitsanzeige, versionsgebundene Qdrant-Ersetzung und Aktivierung nach erfolgreichem Indexlauf implementiert. Synthetische HTTP-, UI-, Client- und Indexregressionen ergaenzt; Standardlauf vor letzter Statuspraezisierung 1.584 bestanden/16 opt-in uebersprungen, danach fokussiert 29/29 und beide Typechecks. Beide Builds sowie Local-only-/Designpruefung vor der Statuspraezisierung erfolgreich. Echte Lizenzdateien und Zielserver bleiben fuer eine gesonderte Abnahme unberuehrt. Keine PostgreSQL-Migration und kein Scanner-Reimport.
 
 Verified 2026-09-23 (Phase 7 and Phase 13D review fixes): Scoped Defender acceptance now rejects a device not present in the selected same-CVE source occurrence while retaining cross-occurrence identity conflict detection. Saved ISO mappings remain available during Qdrant outages. AI Overview preserves and labels the last successful result after a failed regeneration. Synthetic domain, repository-command, service and rendered-panel regressions pass; standard suite 1,576 passed/16 opt-in skipped, builds/typechecks and local-only/design checks pass. No database or scanner-data mutation. Existing device-finding decisions from the affected source pattern need provenance review; no historical decision was silently rewritten.

 The final cross-area sweep measured 34 ms for Result DB, 44 ms for DB Structure and 109 ms for Datahub until the third frame; their asynchronous data requests are not included. Client Info measured 353 ms on a warm visit, while the first visit after filter reset took 991 ms. Pathfinder still performs a necessary first build or rebuild after data/filter changes (1,005 ms after the reset in this sweep); retained unchanged visits avoid rebuilding its data. Continue measuring these separate cold costs when changing either area.
 
 The synthetic 8,257-record benchmark initially measured 5,360 ms cold / 398 ms repeated. Focused post-change runs measured 623–978 ms cold / 1 ms repeated; concurrent full-suite load raised cold times, so those runs are not directly comparable. The reliable regression invariant is zero source-field reads on an unchanged repeat visit. No tenant data, source artifacts or database schema were changed for these measurements.

+## Observations on 2026-09-24 (first workspace load)
+
+Production build, authorized dummy (1,113 aggregate records, 948 GPO settings, 11 referenced Microsoft baselines). Before: Data Hub loaded the complete workspace for its tenant summary and Open loaded the identical scope again; Open took ~8.6 s, of which ~5 s were a sequential request waterfall (including eleven one-at-a-time baseline analyses of 2–4 MB each) and ~3 s a main-thread block in `appendPolicyObservationsToDataset`.
+
+| Cause | Control |
+| --- | --- |
+| Open repeated Data Hub's identical workspace load. | One-time handoff for the exact normalized scope, at most 60 s old and only while no mutating API request started or settled since the load began (`workspace-load-handoff.ts`). |
+| GPO policy requests waited for the scanner model. | With an explicit assessment scope the policy chain starts alongside the model load; its failure is still reported. |
+| Baseline analyses loaded strictly sequentially. | At most three in flight; completion order cannot change guidance because each baseline writes only its own result IDs. |
+| Row analysis repeated header-only work per row and locale-lowercased every cell twice. | Header order/traits once per header list (identity cache holding a copy, so mutation is detected); cells cleaned once; `toLowerCase()` in per-cell paths, pinned equal to `toLocaleLowerCase('de-DE')` by a regression test. |
+
+After: Open following a settled Data Hub selection 0.7 s; tenant click straight to Client Info ~5.2 s (previously the Data Hub load plus 8.6 s). Output was verified byte-identical before and after. The remaining cost is the main-thread dataset build (~1.9 s block in this sweep) because GPO rows are analyzed for both the GPO and the aggregate sheet. Wall-clock values are observations from a hidden desktop browser pane and varied by up to 3× between sessions; `tests/features/workspace-load-performance.test.ts` guards the behavior with deterministic checks.
