The context enrichment (Phase 13E, "context engine"/"Kontext-Engine" in earlier text) is the **Context Engine**. The read-only Report Engine (Phase 7, `src/reporting/`, `server/reporting/`) is an engine in the same sense. Future features arrive as further engines that provide a capability without changing the Core. The UI labels `Context`/`Kontext` stay unchanged. - Explicit user decision 2026-10-05: the regulatory control mapping (Phase 13F, ISO mapping) is the **Compliance Engine** (`src/compliance/`, `server/compliance/`, `tests/compliance/`). It is framework-neutral by intent: ISO/IEC 27001/27002 is its first corpus, later frameworks such as BSI or DORA arrive inside this engine without a Core change. It reads the Core only through `ComplianceReadPort` (single Result DB row by project, filtered Result DB pages, project, assessment and scan-run lists; explicit user decision 2026-10-05: additionally the internal-analysis `policy-evaluation` rows of the same project and timeslot, used solely to read the GPO technical setting ID that the Result DB withholds, so a GPO setting counts once like its rolled-up Work record and the Work ISO facets match it; that ID is never displayed or exported and no other internal field is read) and stores mapping runs, accept/reject decisions, batches and AI overview runs only through its own `ComplianceStore`. Explicit user decision 2026-10-05: all AI integration belongs to this engine. The AI overview (service, model, Client Info panel) moved from the Core into it, and the Result DB `Export JSON` is the engine's 1:1 copy of what its AI features receive: the exact AI overview input built by the same function the overview sends to the model, and every distinct ISO mapping query with the Result DB rows that produce it (the retrieved candidate controls depend on the index and are not exported). The shared model client `server/ai/litellm-client.ts` stays Core platform code. The existing tables of migrations 025 (AI overview runs) and 026 keep their names and data and are owned by the engine; its writes never advance the Core repository revision. Because the Core deletes scan runs and assessments without knowing the engine, the engine removes AI overview runs of a deleted timeslot from its own table on start and on read. The Core project export receives the engine data, including succeeded AI overview runs, beside the Core export at the HTTP route. Its extension points are the Finding Reader `Map ISO controls` action and its window, the Finding Reader `ISO controls` section, the Result DB `Compliance mapping` batch action (formerly `Map all ISO controls`; ISO and BSI) and `Export JSON` action, the Data Hub ISO corpus tile, the Client Info `Compliance` tab (formerly the `Compliance` row and before that the `ISO controls` section) and `AI Overview` tab, and the Work `ISO control` and `ISO theme` facets, and for BSI the Finding Reader `BSI requirements` section, the Client Info `BSI Grundschutz++` tile, the Work `BSI requirement` and `BSI practice` facets and the Data Hub BSI catalog tile. Switched off, the engine also removes the AI overview tab and its requests and the `Export JSON` action. Explicit user decision 2026-10-05: `Map ISO controls` opens a window like `Accepted Risk` with Accept and Reject per control (no third decision value). The Finding Reader lists the controls whose latest decision is accepted in an `ISO controls` section read like `Description`, after the summary fields. Client Info shows the accepted controls of the selected timeslot directly below the Context heatmap in the same tile layout without severity colour, each with its ISO 27002 theme and the number of deviation findings (a GPO setting counts once); a tile opens Work with the `Deviation` status and that control selected in the `ISO control` facet, like a Context heatmap cell. Explicit user decision 2026-10-06 supersedes only the tile layout of that Client Info section, after feedback that it grows too large: the accepted controls are grouped by ISO 27002 theme in ISO order (Organizational, People, Physical, Technological; a theme without hits is omitted). Each full-width theme heading states its number of controls and of distinct findings (a finding counts once per theme) and opens Work with the `Deviation` status and that theme selected in the `ISO theme` facet. Below it, its controls flow in columns of twice the compact tile width, one compact row per control sorted by finding count, showing the Annex A ID, the complete title (wrapped, never truncated) and the authoritative count, without an amount bar (removed the same day because it cost title width); a row opens Work exactly like the former tile. A theme shows its top six controls; a keyboard-accessible `Show all N controls` button below expands that theme and `Show top 6` collapses it again, and every theme starts collapsed for a new timeslot. The theme heading still opens all of its controls in Work. Explicit user decision 2026-10-06, later the same day, supersedes the in-page list and its top-six cap: Client Info shows a `Compliance` row below the Context heatmap with one tile per framework, in the exact environment tile geometry and fact grid (its own `client-compliance-grid` with the same tile rules; the environment row keeps exactly its six tiles), so later frameworks such as BSI or DORA add a tile instead of a section. The `ISO 27001/27002` tile shows `Controls` (accepted controls), `Findings` (distinct findings) and the two themes with the most findings, each with its finding count (fewer when fewer themes have hits; an em dash while loading, never zero). Its `Results` button opens the shared Results window with the complete grouped list described above, without a cap; a theme heading or row there closes the window and opens Work as described. Explicit user decision 2026-10-06, again later the same day, supersedes the two-theme selection of the tile: after `Controls` and `Findings` the tile shows all four themes in ISO order (Organizational, People, Physical, Technological), each with its finding count (`0 findings` without hits, an em dash while loading). A theme with hits is one click target over its whole fact cell and opens Work with the `Deviation` status and that theme selected in the `ISO theme` facet; a theme without hits is not clickable, because the facet offers only values with hits. Hover changes only the cell surface; keyboard focus shows the blue focus ring. All six facts stay visible in this tile at every width, unlike the environment tiles, which show two facts below their measured four-fact width. Explicit user decision 2026-10-05: Work offers the Compliance Engine facets `ISO control` (one value per accepted control, `A.8.20 · Networks security`) and `ISO theme` (Organizational, People, Physical, Technological) in mixed Work and in both GPO entry paths, directly before the permanent final `Source: Scan`; this extends the GPO-only facet list. They read the accepted controls of every mappable finding of the timeslot (scanner findings by occurrence, GPO settings by scope and technical identity), offer only values with hits, count against the other active filters, keep an active selection while loading, and disappear with their filter cleared when the engine is off. Decisions stay global per scanner rule. Provisional explicit user decision 2026-10-05 (may change later), narrowed by explicit user decision 2026-10-09 for ISO and BSI: after a mapping succeeds, single or batch, the engine accepts at most the first two strong proposals in the model's order automatically, a strong proposal being `primary` with `high` or `medium` confidence; weaker proposals wait for a person and without a strong proposal nothing is accepted. The comment is `Accepted automatically: one of the first two strong proposals (primary, high or medium confidence) of the mapping.`; a control that already has a decision keeps it, so a manual reject is never overridden, and a failure of this step never fails the mapping. Explicit user decision 2026-10-08: the Data Hub ISO corpus tile carries the switch `Map new scans automatically` (default off), stored only in the engine's own settings file `regulatory-corpora/auto-mapping.json`, never in a Core table. While it is on, an engine-side backend watcher (`server/compliance/regulatory-auto-mapping.ts`) checks every 10 seconds through `ComplianceReadPort` only: the active (not superseded) scan runs and, because GPO backups create no scan run, the GPO deviation rows of every timeslot as filtered Result DB pages. For each new scan run it starts the existing ISO batch over that run's deviations, and for each timeslot with new GPO deviation rows a batch over that timeslot's GPO deviations, each with a stable idempotency key. Rules with a succeeded or active mapping of the current pipeline versions are reused, so only new rules reach the model; failed mappings are retried, and the provisional auto-acceptance applies unchanged. What exists when the watcher starts or is switched on is the baseline and is not mapped retroactively; new imports wait while mapping is unavailable. Switching the Compliance Engine off in the Engines popup also switches this server-wide setting off (once, from any view); switching the engine on again leaves it off. Already started batches are never cancelled. Explicit user decision 2026-10-08 supersedes only the placement of the 2026-10-06 Client Info `Compliance` row: it is its own Client Info tab `Compliance`, after Overview (and Microsoft Defender for IoT) and before `AI Overview`, shown while the engine is on and the backend can deliver the timeslot; the Overview no longer contains it. The tab keeps the framework tile row exactly as decided, including each tile's `Results` button and window, so later frameworks add a tile there. Explicit user decision 2026-10-08, later the same day (supersedes the timeslot-only, batch-only history first agreed): because mappings and decisions are global per rule, the tab heading carries a `Last mapping` button showing the newest mapping of any client (`Last mapping: · Automatic|Manual|Single finding`, followed by `Other timeslot`, `Other client` or `Unknown` when it is not this timeslot and by the status while not completed, or plain `No mapping yet`). It opens the window `Mapping history` (formerly `ISO mapping history`) with at most 50 entries, newest first: every mapping batch of every client and every single finding mapping (`Map ISO controls` and `Map BSI requirements` in the Finding Reader); explicit user decision 2026-10-09 adds the direct BSI mappings, so the button names a BSI mapping with `· BSI` after the date and an ISO mapping keeps its label. Columns: Started, Framework (`ISO 27001/27002` or `BSI Grundschutz++`), Trigger, Scope, Status and the content-free counts Findings (a batch's own eligible findings; an em dash for a single mapping), Sent to model, Reused, Succeeded and Failed. Entries carry no client, rule, scope ID, filter or key. A batch is Automatic when the watcher started it (idempotency key prefixes `auto:`/`auto-gpo:`), otherwise Manual. Explicit user correction 2026-10-08: Scope names where an entry came from relative to the shown timeslot: `This timeslot` (a batch whose scope shares an assessment or scan run with it, or a single mapping started there), `Other timeslot` (same client, another timeslot), `Other client`, or `Unknown` (a single mapping without a recorded origin). `Map ISO controls` sends the timeslot the Finding Reader shows; the server validates it against the client and stores only SHA-256 origin tokens of the client and of each assessment and scan run, never their ids, because mapping runs are global and exported with every client; an invalid timeslot leaves only the client as origin. Every mapping run records its trigger (`single` or `batch`) in the engine's own run data; runs from before 2.21.0 record none and are not listed as single mappings, because they cannot be told apart from batch runs. While a listed entry runs, the tab refreshes every five seconds without falling back to em dashes. Returning to the tab shows the last overview of that client and timeslot at once from a bounded in-memory cache of at most eight timeslots and always requests a fresh one, which replaces it; a failed refresh keeps the shown values. - Explicit user decision 2026-10-08: BSI Grundschutz++ is the second framework of the Compliance Engine, limited to the 901 Kernel requirements (class `BSI-Stand-der-Technik-Kernel-G0`) of the BSI Stand-der-Technik-Bibliothek; Methodik and risk-management requirements stay out. Like the MITRE catalogs, the catalog and the official BSI mapping ISO/IEC 27001:2022 Annex A -> Grundschutz++ are compact, commit-pinned snapshots in `server/compliance/data/` with source URL, source SHA-256 and the CC BY-SA 4.0 attribution, generated by `server/compliance/update-bsi-assets.mjs`. Explicit user decision 2026-10-08, later the same day: like the MITRE matrix tile, a Data Hub tile `BSI GRUNDSCHUTZ++ KERNEL` (below the ISO corpus tile, shown while the engine is on) names the active catalog date, mapping version and origin (`Bundled` or `Updated`) and offers `Update from BSI`, which fetches only the two fixed official files from the BSI repository `main` branch in the backend, validates them fail-closed, never activates a state older than the active or bundled one, and stores the compact result with source URL and SHA-256 only in the engine folder `regulatory-corpora/bsi/` (see `SECURITY.md`); `Use bundled catalog`, offered only after an update, returns to the pinned snapshots. Derived requirements follow the active catalog at once. Stage 1 derives BSI requirements from the accepted ISO controls of a rule through that mapping, without a model call or migration: each derived requirement names its ISO control and the mapping relationship, is labelled as derived, is never stored as a decision and never changes an ISO decision, and a mapping target missing from the catalog is reported, never reinterpreted. The Finding Reader `BSI requirements` section follows `ISO controls`; the Client Info `Compliance` tab shows a `BSI Grundschutz++` tile beside the ISO tile (`Requirements`, `Findings` and the practices with most findings, as many as the square tile fits, at least four and at most ten (explicit user decision 2026-10-12); its `Results` window lists every requirement by practice in catalog order), whose rows and practices open Work with the `Deviation` status and the `BSI requirement` or `BSI practice` facet; Work offers these two facets after the ISO facets and before `Source: Scan`, only while a requirement is derived. BSI texts may be shown with attribution. Explicit user decision 2026-10-09 (stage 2, migration 029 after a verified backup): the model also maps a rule directly to Kernel requirements from its own BSI corpus (`corpusId` `bsi-grundschutz-kernel` in the shared Qdrant/BGE-M3 path, built from the active catalog from the Data Hub BSI tile via `Build search index`/`Rebuild search index` or on the first BSI mapping), started from `Map BSI requirements` in the Finding Reader `BSI requirements` section or from the BSI part of the Result DB `Compliance mapping` window. Mappings and decisions carry a framework (`iso27001`, `bsi-kernel`; ISO objects keep their earlier shape) and the same auto-acceptance rule applies. The Client Info `Compliance` tab tile `ISO ↔ BSI review` compares per rule the directly accepted BSI requirements with those derived from the accepted ISO controls: `Consistent` (one direct requirement in the derived set), `Inconsistent` (reachable but none derived) or `No ISO reference` (none reachable through the BSI mapping); its Results window lists the rules by a Result DB row, offers Accept/Reject through the normal decision path and `Mark reviewed` for one fingerprint of the compared sets (engine table `assessor_regulatory_consistency_reviews`). The comparison is derived only and never changes, rejects or blocks a decision. Explicit user decision 2026-10-09: ISO and BSI retrieval are hybrid: the model restates the public query once in German, and dense English, dense German and German keyword (BM25) rankings are fused by reciprocal rank; BSI leaves out the BES, DLS, GEB and PERS practices and sends 16 candidates, and each ISO candidate carries its full ISO/IEC 27002 control text (never sent to the browser). The automatic mapping of new scans does not cover BSI. +- Explicit user decision 2026-10-13: the timeslot comparison of `docs/TIMESLOT_COMPARISON_PLAN.md` (P1-P6) is the **Comparison Engine** (`src/comparison/`, `server/comparison/`, `tests/comparison/`). It compares two explicitly selected timeslots A and B of the same client and owns its comparison logic; every contract and the acceptance matrix of that plan stay binding (object/scope identity, absence is never a remediation without a declared profile negative-evidence contract, a missing source keeps its open deviations as unverified, score delta only over the shared population). It never changes, re-derives or overrides a Core verdict, score, review, risk acceptance or Result DB row. A retained value change of a still deviating setting is shown neutral, neither better nor worse. Planned extension points (separate Core change): a Client Info `Compare` tab as entry, a Work `Change` facet with change badges and a Finding Reader `Compare` section with A and B side by side. The Core Phase 8 scan-run comparison (`compareScanRuns`, local comparison rules, `assessor_comparisons`) stays Core in `src/evaluation/scan-run-comparison/`. Engine storage for carried-forward obligations needs separate approval, backup and migration. - Engines may read the Core without restriction but never write to, change or override it. They read only through a declared read-only port and the read-only database access, never through Core tables or internal modules directly. What an engine shows or exports still obeys the Core's privacy and Result DB disclosure rules. - Dependencies point one way: an engine depends on the Core, the Core never depends on an engine. The Core works unchanged with every engine switched off; each engine keeps a permanent on/off invariance test like the Context layer's. Engines do not build on each other except through another engine's published results. - An engine that needs storage gets its own schema or tables after separate approval with backup and migration, never columns in Core tables.
