fix(work): end a same-change focus when another area is opened

Switching areas through the main navigation kept the related-findings group focus, so Work still showed only the group afterwards. The navigation now releases the focus, restoring the previous Work view state, and keeps the chosen area.

+oeffentliche Dateien der BSI-Stand-der-Technik-Bibliothek ab
+(`https://raw.githubusercontent.com/BSI-Bund/Stand-der-Technik-Bibliothek/main/...`:

+Grundschutz++), ausschliesslich ueber HTTPS, ohne Weiterleitung, mit 120 s
+Zeitlimit und 32 MiB je Datei. Es werden keine Projekt-, Finding- oder
+Kundendaten gesendet; die Anfrage enthaelt nur die feste URL. Der Browser
+bleibt Same-Origin und erreicht GitHub nicht selbst.
+
+Beide Dateien sind nicht vertrauenswuerdige Eingabe: Sie werden nur als JSON
+gelesen und vom Konverter fail-closed geprueft (Version, IDs, Parameter,
+Beziehungen); ein ungueltiger oder unvollstaendiger Stand wird abgelehnt, und
+der aktive Katalog bleibt unveraendert. Gespeichert wird nur der kompakte
+Kernel-Katalog samt Zuordnung mit Quell-URL und SHA-256 atomar in
+`<artifact root>/regulatory-corpora/bsi/active-catalog.json` (Dateimodus 0600,
+privates Verzeichnis, kein Symlink). Ein Stand, der aelter als der aktive oder
+der mitgelieferte ist, wird nie aktiviert; `Use bundled catalog` loescht nur
+diese Datei. Keine PostgreSQL-Tabelle, kein Finding und keine ISO-Entscheidung
+wird veraendert; abgeleitete BSI-Anforderungen folgen dem aktiven Katalog. Wie

+# Protected scanner import contracts
+
+User decision, 2026-10-09: working scanner imports are ASSESSOR crown jewels. This is a Core compatibility boundary in Phase 13A, not another engine or another worker.
+
+## Release gate
+
+Run `npm run test:imports` for every importer, shared helper, dependency or Platform change. `npm test` runs it before the complete suite; `npm run build` runs it through `prebuild` before either production build. Any failure blocks release. Direct build commands are not a substitute for this gate.
+
+The gate runs Vitest in CI mode, without an update option. Changed and missing snapshots fail. It includes all importer and scoring tests and the Node runtime, worker, base64, batch HTTP and server API tests, plus GPO/GPP server ingestion, Registry.pol, security templates, preferences, advanced audit, ADMX and domain ingestion tests. The existing tests for invalid input, safety limits, native score priority and safe fallback stay required.
+
+## Registered reference inputs
+
+`tests/importers/import-contracts.json` is the additive format register. Each entry names a tool, format, exact synthetic fixture, variant, filename/MIME, expected approved Work-record count and SHA-256 of UTF-8 fixture text with CRLF normalized to LF. Excel is generated from the protected CSV using the existing XLSX library; it is checked through both runtime paths.
+
+Initial coverage: 18 variants across all five registered import profiles, using every existing synthetic scanner fixture plus a synthetic Maester multi-tenant fixture. PingCastle HTML/XML; CIS-CAT HTML details, future control sections and summary/outcomes; Purple Knight HTML, JSON and summary CSV; Maester CSV, Excel, legacy HTML, static object literal, current JSON-script declaration, bare JSON-script data, const/let/var and multi-tenant HTML; generic CSV.
+
+For each reference the test exercises file selection/import, recognition, non-error preview, explicit confirmation of mappings and canonical batch creation in both browser and Node backend. Both paths must produce identical protected results. Committed snapshots retain finding identity, original and normalized values, source locations, field roles, status/outcome/execution state, severity, score, evidence and its finding association, source tables, scanner report sections and environment observations. The scoring projection is protected too. Generated IDs/links, import timestamps, processing versions and mapping-confidence explanations are not application findings and are excluded where applicable; original source objects are never recursively scrubbed.
+
+The registry test rejects removal of an initial contract and requires a reference for every registered profile and every `.synthetic.` fixture. Baselines are inspectable output, not hashes of opaque canonical objects. Existing structural and semantic assertion tests remain in the gate to avoid accepting an incorrect initial baseline by snapshot alone.
+
+## Extending and maintaining contracts
+
+1. Use only invented Dummy data. Build a fixture for the exact report structure; retain original-value edge cases and provenance. Do not read customer reports or copy customer values into a fixture.
+2. Add a uniquely named register entry and its normalized fixture checksum. Keep existing entries and fixtures. Add exact assertions for the new behavior, including the scoring declaration required by the project guidance.
+3. Generate only the new case's initial snapshot using a narrowly selected test, inspect its fields and approved count, and run the complete gate without update mode. Never blanket-update existing snapshots to resolve a regression.
+4. Run the full tests and both builds, and record coverage/limits in the implementation plan. Do not claim support for a vendor format solely because it is listed by the vendor.
+
+Changes to established expected behavior, removal of a contract or replacement of a reference require the user's explicit agreement for that exact change and current Core consent for affected areas. A failing test must normally be fixed by restoring compatibility or adding another input variant. Test suppression, hash replacement and baseline regeneration are not repairs.
+
+## Limits and current gaps
+
+This protects registered examples and existing behavioral suites, not unknown future vendor formats or all possible report values. An exploratory raw Maester JSON object produced the generic profile rather than Maester recognition; that shape has not been promoted to a supported Maester contract or changed in this protection batch. Additional supported structures should be registered incrementally; unsupported structures need a separate additive implementation and regression tests. No external CI provider is configured in this repository; a future CI pipeline must invoke the same mandatory `npm test`/`npm run build` entry points.
+
+The protection is executable for normal test/build commands and binding for agents and reviewers through AGENTS.md. It cannot prevent someone with repository write access from intentionally changing the gate itself; such a change is Governance/Platform work and remains subject to Core consent and review.

+
+## 1. What ASSESSOR is
+
+![ASSESSOR at a glance](images/onboarding/01-big-picture.svg)
+
+Security consultants run several scanners against a client environment, such as
+PingCastle, Purple Knight, CIS-CAT, Maester and Defender for IoT, and collect
+Group Policy (GPO) backups. Each tool writes its own report format, uses its own
+words for "failed" or "critical", and scores differently.
+
+ASSESSOR takes those reports and:
+
+- **imports** them safely, whatever the format (HTML, XML, JSON, CSV, Excel, GPO
+  backup folders),
+- **normalizes** every result into one canonical finding model and keeps the
+  original values next to the normalized ones,
+- **evaluates** them: verdicts, GPO baseline comparison, scores and security
+  domains,
+- **stores** everything in PostgreSQL with full provenance (which file, which
+  table, which row),
+- **presents** the result to the analyst (Work, Finding Reader, Pathfinder) and
+  to management (Client Info, reports),
+- **discloses** a privacy-safe version, the **Result DB**, that may leave the
+  client context.
+
+Optional **engines** add capabilities on top: context clusters, reports and
+regulatory (ISO) mapping with AI. They read the Core's results and never change
+them.
+
+What ASSESSOR is **not**: it does not scan anything itself, it does not change
+a verdict a scanner reported, and it never claims effective device state from a
+GPO backup.
+
+---
+
+## 2. Vocabulary you will hear every day
+
+| Term | Meaning |
+|---|---|
+| **Client** (code: *project*) | One customer. Created in Data Hub. |
+| **Timeslot** (code: *assessment*) | One assessment period of a client. Holds the scan runs of that period. |
+| **Scan run** | One confirmed import of one or more report files from one tool. |
+| **Finding definition / occurrence** | The definition is the stable identity of a check (tool + rule). An occurrence is that check showing up in one scan run. |
+| **Original vs. normalized value** | Every mapped value keeps the source value (`originalValue`) beside ASSESSOR's normalized value. Originals are never overwritten. |
+| **Provenance** | Every value knows its import file, source table, row/column or object path. |
+| **Scanner profile** | Tool-specific knowledge (field mapping, status/severity vocabulary, native score, first-read fields) in `src/profiles/<tool>/`. |
+| **Deviation** | A failed check, shown with the `Deviation` status in Work. The default Work filter. |
+| **Verdict** | ASSESSOR's authoritative evaluation of a GPO setting (see section 5). |
+| **Review / risk acceptance** | Client-owned work state. Stored separately and kept across reimports. |
+| **Result DB** | The stored, privacy-checked projection of all results. The only dataset that may be shared or fed to AI. |
+| **Core / Core area** | Everything ASSESSOR does today. It is split into areas such as Ingest or Evaluation. Changing an area needs explicit consent (section 7). |
+| **Engine** | An optional capability that reads the Core and never writes to it: Context, Report, Compliance, Comparison. |
+| **Extension point** | A place in a Core view where an engine shows its content, for example the Finding Reader `Context` section. |
+
+---
+
+## 3. A typical assessment in the application
+
+![A typical assessment in the application](images/onboarding/07-user-journey.svg)
+
+| View | What you do there |
+|---|---|
+| **Data Hub** | Create and select a client, import scan reports and GPO backups, manage timeslots, update ATT&CK/D3FEND catalog references, upload the ISO corpus. Its six donuts summarize the selected client's results. |
+| **Data Flow** | The live database schema (tables, columns, relationships) and the interactive engine diagram `Engines & relationships`. Available without a selected client. |
+| **Work** | The analyst workbench: the list of all findings with facet filters (status, source, category, security domain, context cluster, ISO control and theme), the **Finding Reader** (first a `Problem` and a `Next step`, then background and evidence), reviews, risk acceptance and CSV/MD/HTML exports of the current filtered set. |
+| **Client Info** | The executive picture: overall score, security domains, environment facts, context heatmap, the compliance tile, reports and the AI overview. Almost every tile opens Work with the matching filter. |
+| **Pathfinder** | A graph of findings, targets, ATT&CK techniques/tactics, D3FEND defenses and context clusters. `Extract Path` isolates one node and its neighbours. |
+| **Result DB** | The privacy-safe, stored dataset of all results: filter, inspect the redaction trace of a row, export JSONL, start ISO mapping batches, `Export JSON` of the AI input. |
+
+The blue **Engines** button in the toolbar switches the optional engines on or
+off for you. The Core is always on.
+
+---
+
+## 4. From scan report to stored finding
+
+![From scan report to stored finding](images/onboarding/02-import-pipeline.svg)
+
+An import always has two stages. Nothing is saved until the analyst confirms.
+
+**Preview (in memory).**
+
+1. **Upload.** In Data Hub, inside a client, `Import Data`. Up to 50 files per
+   batch, 100 MiB per file.
+2. **Isolated worker.** Every file is parsed in a separate worker with time and
+   memory limits. Imported files are untrusted: scripts never run, Excel
+   formulas stay off, embedded report data is read with a small static grammar
+   and never evaluated. Limits: [`IMPORT_SECURITY_LIMITS.md`](IMPORT_SECURITY_LIMITS.md).
+3. **Format parser.** Turns HTML, XML, JSON, CSV or Excel into one
+   format-neutral `ImportDocument`: tables, fields and source positions
+   ([`IMPORT_INTERMEDIATE_MODEL.md`](IMPORT_INTERMEDIATE_MODEL.md)).
+4. **Recognition.** Decides which tool produced the file, which tables are
+   relevant and what each column means, with a traceable confidence score. Low
+   confidence requires the analyst to confirm
+   ([`RECOGNITION_ENGINE.md`](RECOGNITION_ENGINE.md)).
+5. **Scanner profile.** Applies the tool's knowledge. Profiles **extend** the
+   generic pipeline. They never bypass it.
+
+**Commit (one transaction).**
+
+6. **Preview review.** The analyst sees tool, confidence, warnings, unmapped
+   fields and SHA-256 duplicates, and selects files.
+7. **Canonical model.** Project, assessment, scan run, import files, source
+   tables, finding definitions and occurrences, original fields, mappings,
+   evidence and diagnostics ([`CANONICAL_MODEL.md`](CANONICAL_MODEL.md)).
+8. **Atomic commit.** One database transaction and one repository revision. An
+   error leaves nothing half-imported.
+9. **PostgreSQL.** The system of record: relational keys plus the full
+   versioned canonical object as JSONB.
+10. **Read models.** The unified result projection, the Work sheets and the
+    materialized Result DB rows are rebuilt and checked.
+
+### Supported sources
+
+| Profile | Tool | Native overall score |
+|---|---|---|
+| `pingcastle` | PingCastle AD health check | `100 - native risk` |
+| `purple-knight` | Purple Knight for AD and for Entra ID (separate scopes) | native posture 0-100 |
+| `cis-cat` | CIS-CAT benchmark results | native benchmark score |
+| `maester` | Maester (Entra / M365 tests) | none, so the pass rate is used |
+| `defender-for-iot`, `defender-for-iot-alerts` | Microsoft Defender for IoT inventory and alerts | declared in the profile |
+| `group-policy` | GPO backups | pass rate of configured, comparable settings |
+| `generic` | any other CSV/JSON/XML/HTML/Excel table | no native score is inferred |
+
+### Reimport
+
+When a parser or profile changes in a way that affects stored data, the change
+gets a new processing-manifest version and affected imports are marked for
+reimport ([`REIMPORT_POLICY.md`](REIMPORT_POLICY.md)). A reimport must use
+byte-identical files (same SHA-256 set). It replaces scanner-derived records
+only. Reviews and accepted risks move to the new records through a unique
+scanner/rule/asset identity and are never guessed by title.
+
+---
+
+## 5. GPO backups: a path of their own
+
+![How GPO backups become verdicts](images/onboarding/03-gpo-evaluation.svg)
+
+GPO backups are not scanner reports, so they get their own pipeline in
+`server/gpo/` and `src/gpo/`:
+
+1. A backup folder (uploaded as `.zip`) contains `Backup.xml`, `GPReport.xml`,
+   `Registry.pol`, `GptTmpl.inf` and Group Policy Preferences.
+2. An isolated **inventory worker** classifies and parses every artifact.
+3. Each instruction is resolved to its **technical setting ID** (registry
+   value, security template setting, user right, and so on).
+4. All backups of the timeslot are collected **per setting and scope**. The
+   source of every value stays attributed.
+5. The settings are compared with every applicable **Microsoft Security
+   Baseline** release.
+
+The result is exactly **one rolled-up verdict per technical setting**:
+
+- **Deviation (Fail).** At least one comparable, in-scope configured value
+  fails. This counts in the score.
+- **Passed.** Every applicable member value matches. This counts in the score.
+- **Review required.** Applicability or precedence is unresolved. ASSESSOR does
+  not invent a fail.
+- **Not configured.** Recommended by the baseline but absent from the analyzed
+  backups. Score-neutral, and never a remediation obligation by default.
+- **No baseline rule.** Configured, but no baseline recommends it.
+  Score-neutral.
+- **Not comparable.** A Group Policy Preference. Preferences have no policy
+  identity and are never compared with a baseline.
+
+**Conflicts** and **Duplicates** are diagnostic flags shown beside the verdict.
+They never replace it. **Not linked** means the backup's own report lists no
+enabled link. All of this describes the **backup configuration**, never the
+effective state of a device. Details: [`GPO_BASELINE_EVALUATION.md`](GPO_BASELINE_EVALUATION.md).
+
+---
+
+## 6. Evaluation: verdicts, scores, security domains
+
+- **Scanner outcomes are authoritative.** If a scanner says `fail` or
+  `warning`, ASSESSOR shows a finding and does not question it. Normalization
+  maps the tool's words to shared statuses and severities and keeps the
+  original next to them.
+- **Scoring is native-score first** ([`SCORING_MODEL.md`](SCORING_MODEL.md)).
+  If the exact file and scan run carry a valid native overall score, that score
+  is used. Otherwise the pass rate `passed / (passed + deviations)` is used,
+  where the result population supports one. The two are never mixed for one
+  scan. Not run, error and unknown results do not count as passes.
+- **Security domains.** Every check gets exactly one of six domains: Identity &
+  Authentication, Privileged Access & Delegation, AD Infrastructure & PKI,
+  System Hardening, Cloud & Collaboration, Monitoring & Recovery. One
+  classifier (`src/evaluation/security-domains.ts`) with per-profile mapping
+  tables serves Work, Client Info and the reports. It reads structured fields
+  only, never the title, prose or outcome.
+- **Comparison between timeslots** works on the canonical model and does not
+  change findings ([`COMPARISON_ENGINE.md`](COMPARISON_ENGINE.md),
+  [`TIMESLOT_COMPARISON_PLAN.md`](TIMESLOT_COMPARISON_PLAN.md)). Progress is
+  proven by a rescan, never by a self-reported status.
+
+---
+
+## 7. The Core Engine and the optional engines
+
+![Core Engine and optional engines](images/onboarding/04-core-and-engines.svg)
+
+**The Core Engine** is ASSESSOR with all its existing functions. It is
+authoritative, owns all Core data and works unchanged with every engine
+switched off. It is divided into **Core areas**. The exact path map is in
+[`.claude/hooks/core-areas.mjs`](../.claude/hooks/core-areas.mjs):
+
+| Area | Typical paths | Responsibility |
+|---|---|---|
+| Ingest | `src/importers`, `src/recognition`, `src/profiles`, `src/gpo`, `server/gpo`, import workers | getting data in |
+| Normalization | `src/domain` | canonical model, finding identity, status/severity |
+| Evaluation | `src/evaluation` (incl. `scan-run-comparison`), `src/scoring` | verdicts, comparison, scores, security domains |
+| Store | `src/persistence`, `server/postgres` | repositories, PostgreSQL, migrations |
+| Client Records | reviews, risk acceptances, review transfer on reimport | client-owned state |
+| Disclosure | `src/domain/result-db-disclosure.ts`, `src/exports` | Result DB policy, exports |
+| Reference Catalogs | `src/references`, `server/reference-data` | ATT&CK, D3FEND and other catalogs |
+| Shared Kernel | `src/shared` | shared helpers |
+| Presentation | `src/app`, `src/features`, `src/components`, `src/styles` | all views |
+| Platform | `server/`, `src/api`, build, deploy, `package.json` | backend, API, product version |
+| Core Tests | `tests/`, `fixtures/` | acceptance tests |
+| Governance | `AGENTS.md`, `CLAUDE.md`, `.claude/hooks` | the rules themselves |
+
+**Core consent.** A change to a Core area needs explicit consent in the chat
+message, for example `Core-Freigabe: Evaluation, Store`. It applies to that one
+message only. `Core-Freigabe: alle` releases every area except Governance. This
+binds every coding agent and every person. For Claude Code a hook enforces it.
+Documentation under `docs/` is not gated.
+
+### The engines
+
+| Engine | Code | What it does | Storage |
+|---|---|---|---|
+| **Context Engine** | `src/assessment-context/`, `src/features/context-layer/` | Gives every deviation a context cluster, in a fixed order of tiers: *catalogued* (catalogue rule, CIS section, declared ATT&CK technique), *recognized* (distinctive terms, technical anchors) or *estimated* (local TF-IDF similarity, category fallback). Deterministic, no AI. Shown as badges, the `Context Cluster` facet, the Finding Reader section and the Client Info heatmap. A context statement says "favours", never "exploitable". | none (in memory) |
+| **Report Engine** | `src/reporting/`, `server/reporting/` | Builds the Management Report (German, offline, no LLM, requires published Context results) and the Technical Report from one shared projection. | own file archive, separate read-only DB pool |
+| **Compliance Engine** | `src/compliance/`, `server/compliance/` | Maps findings to regulatory controls; ISO/IEC 27001/27002 is the first framework. Owns **all AI integration**: ISO mapping and the AI overview. | own tables in PostgreSQL, Qdrant index |
+| **Comparison Engine** | `src/comparison/`, `src/features/comparison/`, `server/comparison/` | Compares two timeslots A and B of one client: verified resolved, still open, unverified, new, regressed and neutral value changes (see `docs/TIMESLOT_COMPARISON_PLAN.md`). Shown in the Client Info `Compare` tab. | none yet (own schema planned) |
+
+**Engine rules**:
+
+- Engines read the Core only through a **declared read-only port**. A port is a
+  `Pick<AssessorRepository, ...>` that contains read methods only, for example
+  `ComplianceReadPort` in `src/compliance/compliance-store.ts`. They never
+  import Core internals or touch Core tables.
+- Dependencies point one way: an engine depends on the Core, never the reverse.
+  Engines do not import each other. They meet only through published results,
+  for example the Context publication that the Management Report consumes.
+- An engine never writes Core data and cannot create findings. New scanners,
+  parsers and importers are always Core changes.
+- An engine that needs storage gets its **own** tables after separate approval,
+  with backup and migration. It never adds columns to Core tables.
+- Every engine has a permanent **on/off invariance test**. Work, Client Info,
+  scores and the Result DB must be identical with the engine on and off.
+- `tests/architecture/core-engine-boundary.test.ts` enforces the import
+  direction.
+
+---
+
+## 8. Which data can be used where
+
+![Which data can be used where](images/onboarding/05-data-layers.svg)
+
+This is the most important section for anyone building a feature. ASSESSOR
+holds client security data. Each layer below is derived from the one above it
+and carries less:
+
+| Layer | Contains | May be used by | Must never |
+|---|---|---|---|
+| **1. Original evidence** | Complete scanner originals: source tables, raw fields, host and account names, GPO customer values (*Istwert*), file names | Work, Finding Reader, Results window, internal analysis | leave ASSESSOR, enter the Result DB, reach an AI service |
+| **2. Canonical model** | Normalized and original values, provenance, scores, reviews, risk acceptances | Core evaluation; Context and Report Engine through their read-only ports | be written by an engine or sent to an external service |
+| **3. Result DB** | Materialized, disclosure-checked rows: public rule ID, tool, outcome/severity, Sollwert, comparison relation, baseline *family*, public scanner guidance | Result DB view, API, JSONL export, Compliance Engine | contain an unclassified field, a client identity or an original value |
+| **4. AI input** | The privacy-safe JSON of Result DB rows (`aiOverviewInputJson`) and rule-level check text for ISO queries (`buildRegulatoryFindingQuery`) | the corporate LiteLLM gateway and the embedding service, from the backend only | include assets, per-object values or anything from layers 1-2 |
+
+What the Result DB disclosure policy removes (summary; the binding text is in
+`AGENTS.md` under "UI Result DB filter consistency"):
+
+- GPO customer values and every principal in them, GPO source counts and
+  concrete baseline releases (only the family remains);
+- client-owned review, priority and risk-acceptance state;
+- per-finding scanner scores, versions and functional levels;
+- in scanner prose: exact counts, dates, times and durations become `[count]`,
+  `[date]`, `[time]` and `[duration]`; standalone IPv4 addresses, non-public
+  hosts and GUIDs that are not in the public catalog are redacted as well;
+- ATT&CK/D3FEND references and Pathfinder relations;
+- the client's own names, removed by a per-client identity guard.
+
+Every projection field is classified in `RESULT_DB_FIELD_DISCLOSURE`.
+**Unclassified fields never cross.** Each row carries a content-free trace of
+what was withheld. The Result DB view shows that trace and never the original.
+
+**Privacy-safe testing.** During development, never read, log, quote or
+screenshot real client content: file names, finding titles, field values,
+report text. Use synthetic fixtures. Against a real instance, verify only
+content-free signals such as HTTP status, counts and the presence of an element.

+All AI belongs to the **Compliance Engine**. Both features are opt-in. They run
+only in the backend and are **advisory**: they never change a finding, verdict,
+score, review or risk acceptance.
+
+### A. AI Overview (Client Info, `AI Overview` tab)
+
+1. All Result DB rows of the selected timeslot are read through
+   `ComplianceReadPort`.
+2. `aiOverviewInputJson` (`src/compliance/privacy-safe-export.ts`) builds the
+   privacy-safe input in a deterministic order.
+3. The backend sends it to the corporate **LiteLLM gateway**: HTTPS only, an
+   approved model alias, the key only in the server environment, redirects
+   rejected and no automatic retries.
+4. The answer is parsed as inert JSON and validated against the output schema
+   and length limits. It may reference only rule IDs and facts that are in the
+   input.
+5. The result is rendered as plain text. It is marked stale when its input,
+   model or prompt changes.
+
+Security boundary: [`AI_OVERVIEW_SECURITY.md`](AI_OVERVIEW_SECURITY.md).
+
+### B. ISO control mapping (Finding Reader `Map ISO controls`, Result DB `Map all ISO controls`)
+
+1. One Result DB row, or a filtered batch.
+2. `buildRegulatoryFindingQuery` builds the query from the **rule-level check
+   text** only: title, description, technical explanation and recommendation,
+   passed through the privacy boundary. Assets, per-object values and the GPO
+   customer value are never read.
+3. The query is embedded with the approved embedding model.
+4. **Qdrant** retrieves candidates from the uploaded ISO 27001/27002 corpus
+   (top 32 chunks, grouped into 8 controls). The index can always be rebuilt
+   from the versioned corpus.
+5. The **LiteLLM mapper** proposes controls, grounded only in the retrieved
+   candidates.
+6. **Accept / Reject** per control in a window like `Accepted Risk`. As a
+   provisional rule, the first two proposals are accepted automatically, and an
+   existing decision is never overridden.
+7. Accepted controls appear in the Finding Reader `ISO controls` section, the
+   Client Info `Compliance` tile and the Work `ISO control` / `ISO theme`
+   facets. A proposal indicates relevance. It is not proof of compliance.
+
+Details: [`REGULATORY_RAG.md`](REGULATORY_RAG.md).
+
+### Check exactly what the AI sees
+
+Result DB, then **`Export JSON`**, produces a 1:1 copy of what the AI features
+receive: the AI overview input built by the same function, plus every distinct
+ISO mapping query with the rows that produce it. The retrieved corpus excerpts
+are not included because they depend on the index. Use this export whenever
+you design or review an AI feature.
+
+### Building a new AI workflow
+
+- It belongs in the **Compliance Engine**, or in a new engine with separate
+  approval. Never put it in the Core. The shared model client
+  `server/ai/litellm-client.ts` is Core platform code you may reuse.
+- Its input starts from **Result DB rows (layer 3)** and goes through the
+  privacy-safe export functions. If you need a field that is not there, the
+  answer is a disclosure-policy discussion with the user, not a shortcut to
+  layer 1 or 2.
+- Its output is advisory, validated as inert data, stored only in engine-owned
+  tables and rendered as text.
+- Its tests use synthetic records and a mocked LiteLLM.
+
+---
+
+## 10. Building a new feature: a decision checklist
+
+1. **Which plan phase?** Read [`IMPLEMENTATION_PLAN.md`](IMPLEMENTATION_PLAN.md)
+   and name the phase.
+2. **Core or engine?** Does the feature change how data is imported, normalized,
+   evaluated, stored or displayed? Then it is a Core change and needs
+   `Core-Freigabe: <area>`. Does it add a capability that only reads results?
+   Then it is engine work through a read-only port.
+3. **Which data layer?** Use the lowest layer that is sufficient. Anything that
+   leaves ASSESSOR or reaches an AI service starts at the Result DB.
+4. **Scanner profile work?** Declare `securityScoring`, keep original values and
+   provenance, add a processing-manifest version and mark affected imports for
+   reimport.
+5. **UI?** Read `.claude/skills/assessor-ui/SKILL.md`. Data Hub, Work and
+   Pathfinder are the visual references. Text sizes are 14px for information
+   and 16px for values and prose. Yellow marks selection, blue marks keyboard
+   focus. No new palettes.
+6. **Data flow changed?** Remind the user to update the engine diagram in the
+   Data Flow view (`src/features/db-structure/EngineDataFlow.tsx`), and update the
+   diagrams in this guide.
+7. **Verify.** Run `npm test` and `npm run build`. Add a synthetic behavioral
+   test for the exact interaction. Bump the product version in `package.json`
+   only for a verified release batch.
+

+
+## 11. Your first day in the code
+
+```bash
+npm ci
+```
+
+```bash
+npm run db:up
+```
+
+```bash
+npm run dev
+```
+
+Then open `http://127.0.0.1:5173`. The full setup is in
+[`PROJECT_OVERVIEW.md` section 4](PROJECT_OVERVIEW.md#4-local-development).
+There is one canonical local database. Never create a second one.
+
+Good files to read first, in this order:
+
+| File | Why |
+|---|---|
+| `src/domain/` (canonical model types) | the shape of every finding |
+| `src/profiles/pingcastle/pingcastle-definition.ts` | what a scanner profile declares |
+| `src/recognition/recognition-engine.ts` | how a tool is recognized |
+| `src/persistence/assessor-repository.ts` | the persistence contract every read port picks from |
+| `src/domain/result-db-disclosure.ts` | what may leave ASSESSOR |
+| `src/compliance/compliance-store.ts` | a read-only port example |
+| `src/compliance/privacy-safe-export.ts` | exactly what AI receives |
+| `src/assessment-context/context-engine.ts` | a deterministic engine |

 ## Report B — Technical Report
 
+### Current form (user decisions 2026-10-08, renderer 4.2.0, model 2.1.0, projection 1.5.0)
+
+The preview corrections of 2026-10-07/08 supersede the section list further below. The
+Technical Report is one static DIN A4 document (`@page` A4, 210 mm sheet, no forced page
+breaks), white, without tiles or grey surfaces, in five chapters:
+
+1. **Information**: the Client Info overview facts of the same snapshot, about half a page:
+   the six Data facts, Domain Information without the counts Data already shows, and the
+   six environment tiles (Resilience, Inventory, Password policy, Certificates & PKI,
+   Operating systems, Cloud Information) with their compact four-fact overviews. Built by
+   the same React-free functions Client Info renders
+   (`src/features/dashboard/client-info-facts.ts`); the GPO count follows the GPO backup
+   list (instances of the latest processed run per backup source).
+2. **Lagebild**: one factual sentence; Overall Score and the deviations as the only two
+   donuts (ring sizes 2.5 : 2), the six Security Domains with their Client Info deviation
+   counts and amount bars in the Overall Score tone; problem-field key figures.
+3. **Beziehungen (Pathfinder)**: one transition sentence (domains, problem fields, largest
+   domain and field) and the Security Domain to problem field diagram. No MITRE section.
+4. **Problemfelder**: every published problem field in exact Context heatmap order, as an
+   ASSESSOR list row (severity stripe, disclosure arrow, name, German name, Base Severity,
+   bar, count, share; an open field brackets its stripe into its top and bottom separator).
+   An open field shows situation and technical lever side by side, its Security Domains and
+   every Work record behind it as a slim line (Work severity hexagon and title). A finding
+   line opens the head of its Finding Reader card: status, the reader's badge fields,
+   MITRE badges, the Context problem field, Source Rule ID, the first-read Problem rows
+   (Result reduced to its statement without appended lists or URLs), a collapsed
+   Description (flattened Markdown restored to headings, steps, lists and safe https
+   links) and the recognised ATT&CK/D3FEND references. `Ohne Problemkategorie` and the sum
+   close the list; the partition reconciles to the Client Info deviation total.
+5. **Datenbasis und Datenstand**: collection period, imported reports, record counts, all
+   checks by Client Info result state, and the engine and catalog versions.
+
+Wording states the actual state only; method explanations are not part of the report.
+Scan tools are never named. Printing opens the problem fields but keeps finding cards
+closed. Both reports read the same published Context: the Management Report requires it,
+the Technical Report renders without problem fields when it is unavailable.
+
+### Earlier rebuild (2026-10-07, superseded where the form above differs)
+
+Explicit user decision 2026-10-07 supersedes the content inventory below (sections 1 to 6,
+including the complete per-finding detail and the complete result index): the Technical
+Report is rebuilt as a *report*, not a list of all findings. It goes technically deeper than
+the Management Report, uses only categorisations and clusterings that ASSESSOR already has
+(Context problem fields, Security Domains, native source areas and severities, GPO verdicts,
+Pathfinder relations), avoids redundant information and uses graphics in the ASSESSOR
+application design language. It is generated offline without Internet access and without
+a language model. Renderer 4.0.0 (`src/reporting/technical-report.ts`) with the model
+`technical-report-model.ts` 1.0.0 and the chart primitives `report-charts.ts`:
+
+Follow-up user correction 2026-10-07: ASSESSOR is the only source. Scan tools are neither named
+nor compared; the Pathfinder view connects Security Domains with problem fields; a problem field
+shows only its situation, technical lever and Security Domains. Renderer 4.1.0, model 2.0.0:
+
+1. Lagebild: Overall Score, deviations, passed and assessed as full donuts; key figures.
+2. Problemfelder: every Client Info deviation exactly once in its primary Context
+   cluster (or `Ohne Problemkategorie`) with Base Severity; per problem field the
+   situation, the technical lever and the Security Domains it falls into.
+3. Beziehungen (Pathfinder): Security Domain to problem field diagram; ATT&CK tactics and
+   techniques separated into explicitly assigned and only mentioned; assigned D3FEND
+   countermeasures.
+4. Security Domains: pass/deviation per domain.
+5. GPO-Baseline-Vergleich: all seven GPO verdicts with score-neutral/flag labels,
+   deviations per policy section, contributing and unlinked backups.
+6. Abdeckung und Aussagegrenzen: all records by result state and reading notes.
+7. Umgebung (to move into the report header, see the implementation plan).
+8. Datenstand und Versionen.
+
+All figures are aggregated from the same Work records, result states and Security Domain
+classifier as Client Info (AGENTS.md, Report numbers). Result IDs and every original value
+remain in the archived projection JSON and in ASSESSOR; the HTML does not list them. The
+Management Report now points to ASSESSOR for individual evidence and original
+recommendations. Without a Context result of the same state the problem-field section states
+its absence and every other section remains complete.
+
+The following historical inventory is retained for traceability only.
+
+### Historical inventory (superseded 2026-10-07)

+Ausdrückliche Nutzerentscheidung 2026-10-13: P1-P6 werden als eigenständig abschaltbare **Comparison Engine** umgesetzt (`src/comparison/`, `server/comparison/`, `tests/comparison/`); der Core-Phase-8-Scanlaufvergleich zieht dafür in einen Core-Evaluation-Ort um.

+Ausdrückliche Nutzerentscheidungen 2026-10-13 (ersetzen die genannten Stellen): (a) Zeitbasis ist die ausdrückliche Timeslot-Reihenfolge A vor B; die Forderung nach einer verifizierten neueren Beobachtungszeit in §3.2/§3.4 und in der Matrixzeile „Neuerer Scanzeitpunkt fehlt …“ entfällt. Eine eigene Bericht- oder Backupzeit sperrt nur, wenn beide Timeslots eine nennen und B nicht neuer ist (gleicher oder älterer Bericht: nicht vergleichbar). Importzeit wird weiterhin nie verwendet. (b) PingCastle erfüllt den profilgebundenen Negativnachweisvertrag: eine in B fehlende Regel gilt als behoben bei gleicher Domain, gleicher PingCastle-Engineversion, kompatibler Verarbeitung und ohne sperrende Diagnose; sonst bleibt sie ungeklärt. (c) Beide Timeslots gehören zu einem Kunden: Enthält jeder Timeslot genau einen Bericht eines Scanners und nennt keiner seinen Scope (Maester-Excel ohne Tenant), ist der Kunde der Scope. Ein nur einseitig genannter Scope oder mehrere Berichte eines Scanners je Timeslot werden so nie gepaart; ersetzt §3.1 nur für diesen Fall.

+These inputs are now registered in `tests/importers/import-contracts.json` and checksum-protected by the mandatory import compatibility gate. See `docs/IMPORT_COMPATIBILITY.md`.

 All files below are deliberately small, synthetic, and free of customer or company data. They are regression inputs for the generic import pipeline, not complete vendor golden files. Source-specific recognition and semantic extraction remain part of Phase 6.
