 SafetyNet combines an Electron/Chromium desktop browser, an administrator web console, a local document-inspection service, and a controlled AI gateway. Employees can use approved AI tools while administrators decide which information may leave the organization and where it may go.
 
+The current milestone is the [Windows DLP MVP](docs/windows-dlp-mvp.md): enforce
+confidential-content checks before browser clipboard release and outbound text
+or file transmission, with central policy and local semantic inspection.
+Native public/blocked transfer and restart fixtures pass. Final acceptance is
+still open: a reproducible Chromium WebRTC renderer crash in initial blank
+iframes requires a verified native fix. Other platforms and broader features
+remain outside this milestone.
+
 S Browser uses translucent materials, rounded controls, light/dark themes, and a content-first layout inspired by Safari. Website content is left unchanged.

+# JavaScript lint and dependency audit
+
+Audit date: 2026-10-13. `npm run lint` uses pinned ESLint 10.12.0, `@eslint/js` 10.0.1 and `globals` 17.13.0. Flat configuration enables recommended correctness rules, including undefined identifiers, unsafe control flow, duplicate keys and unreachable code. Node and renderer environments are separate. Serialized isolated-world DOM helpers and classic admin scripts have explicit global contracts. Narrow annotated exceptions preserve intentional control-character rejection, fixed sanitized errors, cleanup failure propagation and sensitive transient text clearing. Unused-variable warnings remain enabled, and the lint command fails on any warning. Existing unused imports and pure dead locals were removed; intentional field-stripping destructures have narrow documented annotations.
+
+Configuration follows the official [flat-config documentation](https://eslint.org/docs/latest/use/configure/configuration-files) and [language-options documentation](https://eslint.org/docs/latest/use/configure/language-options).
+
+`npm audit --omit=dev --json` reports zero npm advisories in production dependencies. Full `npm audit --json` reports eight moderate affected packages and zero high/critical. These eight entries form one development-tool dependency chain, rather than eight independent vulnerabilities:
+
+`electron-builder → app-builder-lib → @electron/get → global-agent → roarr → sprintf-js@1.1.3`.
+
+The underlying [GHSA-hp3w-g68c-fv3c / CVE-2026-97058](https://github.com/advisories/GHSA-hp3w-g68c-fv3c) concerns denial of service when attackers control numeric precision in sprintf format strings. The advisory lists versions through 1.1.3 as affected and no patched release. The registry's latest sprintf-js is also 1.1.3. Consequently there is currently no verified patched leaf version to pin. Npm proposes electron-builder 26.5.0 despite the current pinned 26.15.3; no blind downgrade or `audit fix --force` was performed.
+
+This is a remaining build-toolchain risk. Keep package generation limited to reviewed local source/configuration, avoid attacker-supplied format templates, and recheck the advisory before release. A production npm dependency result does not audit bundled Chromium/Electron, Python/OCR/model runtimes or prove absence of vulnerabilities. Exact Electron remains pinned at 44.7.0. Package fuse tooling is pinned separately as `@electron/fuses@2.1.3`; its package fuse enforcement requires a successful package verification result.
+
+Raw reports remain in ignored local artifacts: `artifacts/npm-audit-production.json`, `artifacts/npm-audit-full.json`, `artifacts/eslint-final.json`. Repeat both audit commands when dependencies change; do not treat this dated snapshot as permanent evidence.

+# Electron quality and performance review
+
+The current Windows DLP MVP keeps security enforcement as the priority. This
+review uses the official Electron documentation as the implementation authority:
+[security](https://www.electronjs.org/docs/latest/tutorial/security),
+[performance](https://www.electronjs.org/docs/latest/tutorial/performance),
+[context isolation](https://www.electronjs.org/docs/latest/tutorial/context-isolation),
+[preloads](https://www.electronjs.org/docs/latest/tutorial/tutorial-preload),
+[IPC](https://www.electronjs.org/docs/latest/tutorial/ipc),
+[coding style](https://www.electronjs.org/docs/latest/development/coding-style)
+and [fuses](https://www.electronjs.org/docs/latest/tutorial/fuses).
+
+## Decisions and implementation
+
+- Keep sandboxing, context isolation, no page Node integration, constrained
+  preload APIs, sender/frame validation and input validation. These need runtime
+  and negative tests; configuration alone does not prove a secure browser.
+- Add pinned ESLint tooling and an explicit Node/browser environment contract.
+  Do not hide findings through blanket rule disabling. Dependency advisory
+  results and lint completion are tracked separately from syntax checks.
+- Profile before optimizing. `scripts/profile-browser-modules.mjs` works with
+  Node CPU/heap profiling flags; output belongs in ignored `artifacts`.
+- Defer OpenTelemetry SDK/exporter loading until diagnostics are authorized
+  and enabled. Keep the lightweight diagnostics API available immediately.
+  This shifts initialization cost to first enablement; it does not remove that
+  cost or claim a measured improvement to full browser startup. Seventeen focused
+  diagnostics regression tests pass after this change.
+- Load text-normalization code on its first inspection rather than immediately
+  upon requiring its wrapper; subsequent calls reuse the module.
+- Keep parsing, OCR and model inference in the isolated worker. Do not move
+  expensive inspection into the renderer or postpone mandatory enforcement.
+- Review main-process synchronous filesystem/cryptographic operations using
+  traces before changing behavior. Build CLI `spawnSync` is separate from the
+  interactive browser event loop.
+
+## Bundling and architecture
+
+[Electron Forge](https://www.electronforge.io/) and the
+[official bundling recommendation](https://www.electronjs.org/docs/latest/tutorial/performance)
+are useful options. The existing electron-builder pipeline already verifies
+Windows runtime contents. Migrating scaffolding is not itself a DLP improvement.
+Any bundling/code-splitting change must retain sandbox-compatible preloads,
+dynamic imports, packaged resources, CSP and exact package verification, and
+must show measured startup or resource improvements before adoption.
+
+The [Palette performance article](https://palette.dev/blog/improving-performance-of-electron-apps)
+was inspected for additional profiling ideas. Type-safe IPC examples are useful
+for maintainability; TypeScript types cannot replace runtime validation of
+untrusted messages. No new IPC framework is needed merely to implement that rule.
+
+## Source freshness
+
+The dependency audit reports zero production advisories and eight moderate
+development/build-toolchain entries, with no high or critical entries at this
+review point. The underlying `sprintf-js` precision-format denial-of-service
+advisory has no patched release reported; suggested electron-builder downgrade
+is not accepted as a safe remediation. These findings remain explicit tooling
+risk, not evidence that the deployed browser is vulnerability-free.
+
+The packaged executable's existing fuse wire was inspected separately from
+JavaScript startup checks. Run-as-Node, Node environment/CLI inspection options
+and ASAR enforcement need package-level hardening and rebuilt-artifact proof.
+All six hardened fuse values and the matching embedded ASAR header hash were
+verified in a rebuilt executable. Actual RUN_AS_NODE and NODE_OPTIONS negative
+launches passed. The CLI-inspector fixture found a startup error dialog instead
+of process termination; the source now exits with a sanitized rejection, but
+the corrected rebuilt package subsequently passed actual negative launches,
+including eleven certificate/feature override cases and copied-ASAR tampering.
+The manipulated archive was rejected before application entry; original archive
+and frozen packaged sources remained unchanged. Evidence:
+`artifacts/package-fuses-proof.json`. Actual signing status remains `NotSigned`.
+
+The supplied Reasonably Secure Electron URL contained a typographic dash.
+Its correct repository is
+[moloch--/reasonably-secure-electron](https://github.com/moloch--/reasonably-secure-electron),
+archived in June 2024; treat it as historical architecture context rather than
+current Electron defaults. The supplied dev.to performance page could not be
+retrieved and was not used as implementation evidence. Other supplied articles
+were inspected, but version-specific changes must be checked against official
+documentation and the actual installed runtime.
+
+This review is in progress. Green syntax/tests and one profiling run do not prove
+that the whole application is clean, fully optimized or independently audited.
+
+## Latest reproducible checks
+
+- Full source suite: 749 tests passed, no failures or skips; see the ignored
+  `artifacts/mvp-final-startup-suite.log`. `npm run lint` passed again with
+  zero warnings on 2026-10-13.
+- A fresh `npm audit --omit=dev --json` reported zero advisories. Development
+  toolchain findings remain tracked separately in `dependency-audit.md`.
+- In the paired single module-load profiles, diagnostics require time changed
+  from 260.119 ms to 67.001 ms after deferred SDK loading. Recorded heap deltas
+  changed from 6,674,088 to 2,460,832 bytes. Both used CPU/heap profiling; these
+  measurements do not establish full application startup or percentile gains.
+- Native Windows DLP fixtures delivered public data and blocked confidential
+  literal and semantic payloads. Restart reused the protected device profile.
+  These are separate from final packaged-artifact acceptance.
+- The protected local OpenTelemetry receiver reported zero rejected writes.
+  Trace `33b46998b44c3179cccd2826d5790c00` correlates browser.request,
+  browser.inspect.local, inspector.inspect, semantic load/inference and durable
+  audit stages. The public-file request took 8966 ms in this synthetic run;
+  a contained local text scan took 1611 ms and model load 662 ms. This identifies
+  repeated model initialization as a measurement target, not permission to
+  weaken process isolation or mandatory scanning.
+- A native WebRTC initial-about:blank renderer crash remains reproducible under
+  Chromium's connection allowlist. The upstream no-op binder fix is recorded
+  in [the upstream regression tests](https://github.com/web-platform-tests/wpt/pull/63420).
+  The separately tested Electron nightly also lacks it. The Windows MVP is not
+  declared stable until an actual fixed runtime passes this negative fixture.
+- The full enrolled browser WebTransport receiver fixture now passes through
+  reviewed DIRECT and fetched HTTPS PAC policies: zero managed packets/bytes,
+  paired against 132 baseline bytes, with ordinary HTTPS submissions working.
+  It records source hashes and genuine operational traces. There is still no
+  per-attempt WebTransport security event because this path produces no
+  Electron webRequest callback; transport denial and audit coverage are separate.

+# Electron security review — 2026-10-13
+
+This is a read-only review of the current source and unpacked Windows executable. It is not a penetration test or a claim of complete Chromium DLP coverage.
+
+## Official references
+
+Electron recommends isolated, sandboxed remote renderers, constrained IPC and navigation, current dependencies, and consideration of custom protocols and packaging fuses. [Security](https://www.electronjs.org/docs/latest/tutorial/security).
+
+A bridge should expose specific actions, rather than raw IPC dispatchers. [Context isolation](https://www.electronjs.org/docs/latest/tutorial/context-isolation), [Preload scripts](https://www.electronjs.org/docs/latest/tutorial/tutorial-preload), [IPC](https://www.electronjs.org/docs/latest/tutorial/ipc).
+
+The subframe option is documented as experimental; sandboxing disables the renderer Node engine. [WebPreferences](https://www.electronjs.org/docs/latest/api/structures/web-preferences).
+
+Fuses can disable alternate startup behavior and enforce ASAR loading/integrity; cookie encryption is another available control. [Fuses](https://www.electronjs.org/docs/latest/tutorial/fuses).
+
+## Implemented boundaries inspected
+
+| Boundary | Current evidence | Assessment |
+| --- | --- | --- |
+| Remote renderer | main.cjs creates WebContentsView with nodeIntegration:false, contextIsolation:true, sandbox:true, webSecurity:true, allowRunningInsecureContent:false; app.enableSandbox() runs before renderer creation | Correct explicit baseline |
+| Website preload | site-preload.cjs asserts sandboxed/contextIsolated, exports no bridge; isolated fixed guards only | No raw IPC exposed to page |
+| Trusted UI bridge | preload.cjs exposes fixed channel methods; onState strips event argument and supplies unsubscribe | Matches constrained bridge pattern; trusted chrome still has powerful actions |
+| Privileged IPC sender | main.cjs ipc helper requires exact window WebContents, main frame and packaged UI URL | Remote and child frames excluded from trusted UI operations |
+| Website reporting IPC | visual-check and page-content bind managed tab and main frame; visual reports validate bounded token/revision/URL | Separate limited channels, not generic dispatch |
+| Permissions and certificates | browserSession request/check handlers deny; certificate-error callback denies | Default deny |
+| Navigation/windows | trusted chrome cannot navigate/open children; managed sites checked by destination policy and agent authority, popups routed to guarded native tabs | Policy-aware handling |
+| UI CSP | index.html self scripts/styles, connect-src none, object/base/form restrictions | Restrictive packaged UI CSP |
+| Startup | startup-security.cjs rejects sandbox/security/isolation bypass and external debugger switches; tests/startup-security.test.mjs | Useful after-entry guard, cannot replace binary fuses |
+
+## Experimental subframe setting
+
+nodeIntegrationInSubFrames:true currently ensures the security preload reaches iframes. It is not evidence that page Node access is enabled: scripts/electron-smoke.cjs explicitly checks srcdoc child require/process/safetynet are undefined and sandbox remains true. scripts/native-tabs-smoke.cjs checks require and bridge absence for active, inactive and replacement tabs. site-preload.cjs additionally fails closed if isolation or sandbox changes.
+
+Do not remove this setting solely because its name contains Node. A replacement must retain srcdoc, initial about:blank, cross-origin/OOPIF clipboard protection and the real native negative tests. The setting remains experimental and increases maintenance risk; test it on every Electron upgrade. Current assertions are not a proof against a framework sandbox vulnerability.
+
+## Historical baseline findings
+
+The following findings describe the initial artifact. Later package/startup
+follow-ups below supersede the fuse and launch findings; the custom UI scheme,
+native RTC stability and production distribution gates remain open.
+
+1. **Historical binary fuse gap, superseded by rebuilt readback below.** An earlier direct read of dist/win-unpacked/SafetyNet.exe found V1 fuse wire 101100011. That older executable enabled RunAsNode, NODE_OPTIONS and CLI inspector and disabled cookie encryption, ASAR integrity and ASAR-only loading. This is historical evidence, not the current fuse status. Final runtime negative probes remain necessary.
+2. **Trusted UI uses file://.** main.cjs builds uiUrl with pathToFileURL and calls loadFile. A dedicated standard secure custom scheme with a strict packaged asset allowlist would reduce file-origin privilege. Migration must update exact trusted-sender URL checks and every native smoke harness; do not enable generic file-system routing or bypassCSP.
+3. **Subframe test breadth.** The inspected native assertion explicitly proves a same-origin srcdoc frame. Extend capability assertions to real cross-origin/OOPIF, initial blank and nested frames alongside existing clipboard bypass tests. No broad assertion about all frame configurations is justified by one fixture.
+4. **Production distribution.** Source pinning and verification do not provide code signing, protected install ACLs or signed updates. External production trust requirements remain open.
+
+## Proposed packaging patch and compatibility
+
+After electron-builder finishes creating win-unpacked, use an explicitly pinned @electron/fuses dependency to flip RunAsNode=false, EnableNodeOptionsEnvironmentVariable=false, EnableNodeCliInspectArguments=false, EnableCookieEncryption=true, OnlyLoadAppFromAsar=true and EnableEmbeddedAsarIntegrityValidation=true on the produced executable. Confirm builder embedded the matching ASAR integrity metadata before enabling integrity; otherwise packaging must fail rather than weaken the setting. Record/read back all fuse values in verify-package.mjs.
+
+Current verify-package.mjs launches SafetyNet.exe with --agent-action and --agent-connection through normal main.cjs and app.whenReady(), not ELECTRON_RUN_AS_NODE. Inspector/inference helpers are external Python/native binaries. No child_process.fork dependency was found in inspected browser/package paths. Thus disabling Node-mode and inspector startup is compatible with the documented current architecture, but only a rebuilt artifact and real packaged verification can prove it.
+
+Add finite negative launch checks for RUN_AS_NODE, NODE_OPTIONS preload injection and inspector flags, plus an isolated copied-ASAR tamper test. A JS source hash comparison alone does not verify runtime archive integrity enforcement. Cookie encryption changes require a migration/reopen fixture for persistent managed sessions.
+
+## Implementation follow-up (verification pending)
+
+scripts/package.mjs now supplies all six hardened fuse settings through electron-builder's supported electronFuses configuration. This runs against the copied executable before signing. scripts/package-fuses.mjs validates the resulting fuse wire and parses the Windows PE INTEGRITY/ELECTRONASAR resource against the exact archive header hash. The installed Electron distribution is not modified.
+
+Two focused unit checks passed. scripts/verify-package-fuses.mjs supplies finite actual-process negative checks and a copied archive tamper fixture; it must pass on the rebuilt artifact before this gap is considered closed. The previously measured executable remains unhardened until packaging runs. The custom-scheme gap remains open.
+
+## Rebuilt artifact verification
+
+The coordinated Windows build completed with all six hardened fuses and a matching embedded ASAR header hash. The standard packaged scanner/runtime/agent verifier passed. Actual negative launches prove RUN_AS_NODE cannot change the normal application entry point and a NODE_OPTIONS require injection does not execute.
+
+The earlier CLI-inspector negative launch exposed an operational defect: Electron's default uncaught-exception handler opened an error box without terminating. The verifier correctly failed on this timeout. Current main.cjs catches startup rejection, emits a fixed message and calls process.exit(1). Final rebuilt negative launch and copied-ASAR tamper probes remain running/pending; absence of an inspector listener alone does not prove terminal behavior.
+
+## Independent final source review
+
+A fresh `npm run lint` passed with zero warnings allowed. `artifacts/mvp-latest-integrated-suite.log` records 748 passed tests and zero failures. These are bounded scenario evidence, not proof of every Chromium transport path. This review changed documentation only.
+
+Current source proves explicit global sandboxing, context isolation and disabled Node integration for remote views; fixed UI bridge methods without raw IPC/event exposure; exact trusted WebContents/main-frame/URL sender checks; denied remote permissions; constrained navigation and popup handling. These match the primary [Security](https://www.electronjs.org/docs/latest/tutorial/security), [Context Isolation](https://www.electronjs.org/docs/latest/tutorial/context-isolation) and [IPC](https://www.electronjs.org/docs/latest/tutorial/ipc) guidance. The experimental subframe option and file-origin UI retain the limitations stated above.
+
+Current rebuilt fuse readback was independently verified with `verifyPackagedFuses`: RunAsNode=false, CookieEncryption=true, NodeOptions=false, NodeCliInspect=false, EmbeddedAsarIntegrity=true and OnlyLoadAppFromAsar=true. The Windows embedded archive-header hash matched. This supersedes the historical fuse wire; final negative launch/tamper probes on the final source-matched package remain pending.
+
+`artifacts/webtransport-native-proof.json` establishes actual page and dedicated-worker delivery to a reachable pinned local HTTP/3 server in the baseline: 132 bytes, including 66 worker bytes, with zero webRequest callbacks. Neither tested disable flag stopped transmission. The authenticated production relay module blocked all receiver packets/bytes while ordinary HTTP remained usable. Main now installs the non-DIRECT relay before tab creation and restores it on policy application. This proves the standalone Session/module boundary; a full enrolled main.cjs page-and-worker receiver test across policy application remains necessary. Chromium's [dedicated WebTransport client](https://raw.githubusercontent.com/chromium/chromium/main/net/quic/dedicated_web_transport_http3_client.cc) rejects a resolved non-DIRECT proxy before socket creation. Revalidate after every Electron upgrade; no claim is made about future HTTP/2 WebTransport implementations.
+
+**Critical unresolved stability gate:** the initial-about:blank native RTC fixture records exit code 3. It must not be presented as completed or stable protection. Source guards and passing unit tests do not close this crash or prove every nested/cross-origin context.
+
+**Startup trust follow-up:** the reviewed denylist accepted certificate-ignore switches and user feature overrides. Root now rejects certificate-ignore/SPKI-ignore, insecure localhost/origin and reduced-security switches. Original application argv rejects user enable/disable-feature and experimental Blink overrides; Electron's internal default disable-features list is preserved. Seven focused startup tests and the updated 749-test suite passed. Actual packaged negative launches for these additional switches are pending a fresh build. The native network gate is `ConnectionAllowlists` (plural), as shown in Chromium's [navigation throttle](https://raw.githubusercontent.com/chromium/chromium/main/content/browser/renderer_host/network_restrictions_navigation_throttle.cc); a singular guessed feature name is not enforcement evidence.
+
+Inspection/inference runs outside the main process, but synchronous audit encryption, writes/fsync and some startup reads remain on it. Traces provide timings for exercised scenarios; no universal responsiveness claim is proven. See Electron's [Performance guidance](https://www.electronjs.org/docs/latest/tutorial/performance).
+
+### Final package follow-up
+
+The new frozen-source Windows build and both package verifiers passed after
+the startup correction. Actual baseline, RUN_AS_NODE, NODE_OPTIONS, CLI
+inspector, eleven certificate/feature override launches and copied-ASAR tampering
+were exercised. All unsafe startup cases terminated with the fixed rejection;
+tampering failed before application entry. The original archive remained
+unchanged. `artifacts/package-fuses-proof.json` records
+`unsafeStartupOverridesRejected=true`. This supersedes the pending package
+statements above. Actual executable status remains `NotSigned`.
+
+### Minimal remaining enrolled WebTransport harness
+
+Implementation follow-up: the enrolled main.cjs harness now passed, recorded in
+`artifacts/fullmain-webtransport-native-proof.json`. The unguarded Window/Worker
+baseline delivered 132 bytes. Actual enrollment, reviewed DIRECT and fetched
+HTTPS PAC→DIRECT policies each yielded zero managed receiver packets and bytes,
+while three ordinary HTTPS POSTs succeeded. Actual correlated operational
+traces exported with zero current/lifetime failures. Exact source hashes are
+included; the later change only normalizes Windows startup arguments. No
+webRequest callback or individual WebTransport audit event was invented. This
+supersedes the proposed-only status below; per-attempt security auditing remains
+open.
+
+Extend the Windows DLP smoke parent to start the existing pinned local HTTP/3 receiver and pass its ephemeral URL and certificate hash to the native fixture. First prove baseline marker delivery. After actual S Browser enrollment, attempt a datagram and stream from the managed page and a real dedicated Worker. Assert receiver connection/byte deltas, then repeat after signed policy application, including enterprise DIRECT/PAC configurations. Require ordinary HTTP/HTTPS and benign prompt delivery to keep working. Record source hashes and fixed facts without credentials or prompt contents. This extension is proposed; it is not implemented or passed here.
+
+Upstream handler evidence: [Electron browser initialization](https://github.com/electron/electron/blob/main/lib/browser/init.ts). The verifier now records a fixed stage and bounded diagnostic output before reporting failure, and waits for child termination before removing its own validated temporary directory.

+# Windows browser transport containment
+
+Electron's HTTP request hooks do not intercept WebTransport payloads. A native
+receiver test with Electron 44.7.0 demonstrated data from both a page and a
+dedicated worker bypassing those hooks, including with the tested QUIC/Blink
+disable flags. The implementation therefore forces every managed browser URL
+through a private non-DIRECT Chromium proxy, with implicit loopback bypass removed.
+The tested Chromium HTTP/3 WebTransport client rejects that proxy route before
+opening its UDP connection. Ordinary HTTP and HTTPS remain available.
+
+`local-dlp-relay.cjs` binds numeric loopback only and authenticates Chromium with
+an ephemeral capability. It forwards approved HTTP or CONNECT traffic; it is not
+a replacement for the native content-DLP gates. Native hooks still inspect text,
+files and headers before release. Policy replacement, quarantine and shutdown
+invalidate relay authority and terminate pending/live sockets. Resolution uses
+the approved Chromium resolver and numeric connection addresses.
+
+The management session retains the centrally configured system/fixed/PAC proxy.
+The relay resolves upstream routes through that session. DIRECT, HTTP PROXY and
+HTTPS PROXY routes are supported; an unsupported or failed route never silently
+falls back to DIRECT. SOCKS and integrated upstream NTLM/Kerberos authentication
+currently fail closed and require an additional integration. Optional Basic
+credentials require `SAFETYNET_PROXY_AUTH_HOST` and `SAFETYNET_PROXY_AUTH_PORT`
+to match the selected upstream endpoint, in addition to protected deployment
+username/password variables. They are not distributed in policy bundles.
+
+Native evidence: `artifacts/webtransport-native-proof.json`. The receiver got
+zero packets/bytes with the private relay while ordinary HTTP loaded. The
+Windows core DLP and real restart fixtures also passed with relay integration.
+Chromium upgrades must repeat this receiver proof; it is version-specific.
+WebTransport-specific denial audit events are not yet observed because the
+native rejection occurs before existing HTTP/relay callbacks. Do not claim
+complete transport-attempt SIEM coverage from the ordinary DLP event pipeline.
+
+Inspected WebSocket/WebRTC support remains the intended compatibility goal.
+Uninspected transports remain restricted until their content gates have their
+own actual receiver and bypass tests.

+# Chromium 152 WebRTC binder backport
+
+Status: source patch prepared and checked; **not compiled or runtime verified**.
+Do not distribute this patch as a proven security fix until the acceptance gates
+below pass against the resulting binary.
+
+## Exact basis and provenance
+
+The adjacent patch targets Chromium `152.0.7977.130`, used by Electron `44.7.0`.
+It backports Chromium commit
+[`46fcf3faed9db394de7046a100301f64c2842f0e`](https://chromium.googlesource.com/chromium/src/+/46fcf3faed9db394de7046a100301f64c2842f0e)
+(CL8485457, bug565837691). Upstream files retain their Chromium copyright notices.
+
+The upstream change fixes a native renderer termination when nested local-scheme
+frames request a missing WebRTC binder under `Connection-Allowlist`. It registers
+the binders consistently, checks the current document policy when binding, and
+uses no-op mDNS/socket implementations to fail without creating network sockets.
+It is a temporary transport denial, not WebRTC payload inspection.
+
+Only two context adaptations were needed: insert the policy helper before the
+older utilities file's namespace close, and place the conditional mDNS include
+beside the existing connection-policy include. The original implementation,
+unit tests, WPT tests and GN entries are preserved. The older public
+`RenderFrameHost` header exposes both APIs used by the helper:
+`HasPolicyContainerHost()` and `GetConnectionAllowlists()`.
+
+On 2026-10-13, the 16 exact touched paths were retrieved individually from the
+official Chromium tag into an ignored scratch repository. Unmodified tag files
+were restored, with LF line endings, and this command completed with exit0:
+
+```powershell
+git -C artifacts/rtc-patch-check apply --check C:/Users/karl/Safetynet/docs/native-runtime/chromium-152-webrtc-binder-backport.patch
+```
+
+This proves textual applicability to the tagged files. It does not establish
+compilation, compatibility with Electron's existing patches, or runtime safety.
+Repeat the check against the complete Electron-patched source checkout.
+
+## Host readiness
+
+Measured host: Ryzen7800X3D, eight exposed logical processors, 16GB RAM (about
+4.5GB free during inspection), and 266.6GiB free on NTFS C:. Installed VS2022
+Build Tools17.14 includes x64 C++ tools but lacks the ATL/MFC component. SDK
+`rc.exe` is26100.7705; `symstore.exe` is28000.2957. No native checkout or
+depot_tools/gclient/GN/Ninja installation was found on PATH.
+
+The [version-specific Chromium requirements](https://chromium.googlesource.com/chromium/src/+/152.0.7977.130/docs/windows_build_instructions.md)
+specify at least8GB RAM and100GB disk, recommend more than16GB RAM, and require
+C++ plus ATL/MFC and SDK26100.7705. This host meets the minimum resources but
+requires toolchain completion. Plan substantially more memory and disk headroom
+for comfortable builds; actual full-checkout and output size remains unmeasured.
+Do not automatically disable endpoint antivirus or change global Git settings.
+
+## Build procedure
+
+Follow [Electron Windows prerequisites](https://www.electronjs.org/docs/latest/development/build-instructions-windows)
+and [Electron GN/patch instructions](https://www.electronjs.org/docs/latest/development/build-instructions-gn).
+Use a separate short path such as `C:/src/electron44`, outside this application.
+Install missing ATL/MFC and depot_tools first. No large downloads or dependency
+changes were performed while preparing this review artifact.
+
+1. Set `DEPOT_TOOLS_WIN_TOOLCHAIN=0` in the build process and prepend depot_tools
+   to that process's PATH. Keep the application workspace unchanged.
+2. Configure gclient with unmanaged `src/electron` pointing at the official
+   Electron repository. Bootstrap its source, check out exact `v44.7.0` in
+   `src/electron`, then sync with branch heads and tags. Confirm its DEPS pins
+   Chromium152.0.7977.130 before applying anything.
+3. From `src`, run `git apply --check <absolute-patch-path>` against the already
+   Electron-patched checkout, then apply. Any failure requires review; do not
+   silently drop hunks. Export the change through Electron's patch system
+   (`e patches`) so future synchronizations reproduce it.
+4. Generate a release configuration using
+   `import("//electron/build/args/release.gn") target_cpu="x64"`.
+   For this constrained host, consider `symbol_level=0`,
+   `blink_symbol_level=0`, `v8_symbol_level=0`, and local execution. These reduce
+   debugging detail; keep a separately instrumented build if native investigation
+   requires symbols.
+5. Build `ninja -C out/Release -j2 electron`. Build the relevant Chromium native
+   test target as well; low parallelism is an initial resource choice, not a
+   measured guarantee against memory exhaustion.
+6. Only after verification, package with
+   `ninja -C out/Release electron:electron_dist_zip` and pin artifact hash,
+   Electron/Chromium versions and backport revision in release provenance.
+
+## Acceptance gates
+
+- Compile and run `NoOpMdnsResponderTest.*` and `NoOpP2PSocketManagerTest.*`.
+- Execute the upstream local-scheme allow/block WPT cases.
+- Run real paired WebRTC data-channel positive controls in initial about:blank,
+  srcdoc, blob and cross-origin frames; prove exact synthetic bytes arrive.
+- Under the actual managed response-header function, repeat the same attempts:
+  no data delivery, no renderer termination, no hanging harness, and successful
+  benign HTTP POSTs. Exercise the initial synchronous iframe window before any
+  navigation or preload; constructor availability alone is not a pass.
+- Verify native socket denial without relying on the JavaScript preload. Check
+  redirects and a site-supplied `webrtc=allow` header cannot relax managed policy.
+- Run the complete Windows DLP MVP native acceptance suite and inspect actual
+  exported OpenTelemetry traces, durable deny events and exporter failures.
+
+## Alternative runtime status
+
+No tested prebuilt alternative is verified. Electron46 nightly20261013 with
+Chromium157.0.8091.0 also crashes under the same blocked about:blank/srcdoc
+attempts; its tagged binder source lacks the no-op implementation. A later
+binary is acceptable only after source inclusion checks and all native gates
+above. Current ignored artifacts retain the original crashes and positive
+controls; an upgrade must not overwrite that evidence.

 # S Browser: Anforderungsabgleich und offene Arbeit
 
+**Scope-Änderung vom 13. Oktober 2026:** Maßgeblich ist jetzt
+[das Windows-DLP-MVP-Ziel](windows-dlp-mvp.md). Nur Upload-, Clipboard-/Prompt-DLP,
+zentrale Durchsetzung und Stabilitäts-/Windows-Abnahme sind aktive Arbeit.
+Die breiteren Anforderungen und Erweiterungen unten bleiben Roadmap.
+
 ## Aktuelle nächste Abnahmen
 
+Aktueller Integrationsstand: 713 Tests bestehen
+(`artifacts/worker-integration-suite.log`). Der echte Admin-Workflow für typisierte
+Login-Regeln, unabhängige Veröffentlichung und Auditor-Leserechte ist geprüft:
+193 abgeschlossene Anfragen mit korrelierten exportierten Traces, eine abgebrochene
+Leseanfrage, keine fehlgeschlagenen Mutationen. Zentrale Worker-Policy und
+restriktive Profilsteuerung sind implementiert; die Laufzeitintegration der
+unveränderlich zugeordneten Agent-Partitionen ist noch in Arbeit. Der letzte
+geprüfte Windows-Build gehört zum vorangegangenen Visual-Export-Stand und ist
+kein Paketnachweis für diese neuen Änderungen.
+
+Unabhängige Registry-Prüfung: Ein synchroner Abbruch innerhalb der
+Session-Erstellung konnte vor der Registrierung des Abort-Listeners eintreten.
+Die Anfrage schlug fehl, während die native Sitzung aktiv blieb. Die
+Laufzeitintegration muss diese Race mit Regressionstest schließen. Ebenso sind
+begrenzte Revocation-Tombstones und begrenzte Setup-/Cleanup-Wartezeiten zu
+prüfen. Requests ohne WebContents dürfen weder über den aktiven Tab noch allein
+über fehlende Initiator-Metadaten eine Identität erhalten. Für interne Downloads
+ist eine nachweisbar private Transportzuordnung erforderlich; ein allgemeiner
+ownerloser Request-Ausnahmepfad ist kein akzeptabler Ersatz.
+
 Gespeicherte Agent-Sitzungen und kontrollierte Credential-Vorbereitung sind für
 ihre dokumentierten nativen Pfade integriert und nachgewiesen. Die vorangegangene
 Controlled-Login-Abnahme umfasste 668 bestandene Tests, Syntaxprüfung, stabilen Windows-Build,

+# Verbindliches Ziel: Windows-DLP-MVP
+
+Der Nutzer hat am 13. Oktober 2026 den bisherigen breiten Funktionsumfang
+ausdrücklich ersetzt. Dieses Ziel hat Vorrang vor älteren Aufgabenlisten:
+Ein stabiler, zentral verwalteter Windows-Browser verhindert, dass vertrauliche
+Texte oder Dateien durch Uploads, Copy/Paste oder KI-Prompt-Versand an nicht
+erlaubte Ziele gelangen. Erst nach der folgenden Abnahme wird das MVP abgeschlossen.
+
+## Abnahmekriterien
+
+1. Ein Administrator kann vertrauliche Textbeispiele und Referenzdokumente
+   registrieren, Regeln veröffentlichen und erlaubte KI-Ziele konfigurieren.
+   Der Browser erzwingt die signierte aktuelle Policy; Benutzer können den Schutz
+   nicht durch lokale Einstellungen abschalten.
+2. Paste per Tastatur, Kontextmenü und Seiten-Clipboard wird vor Freigabe geprüft.
+   Copy und Cut werden ebenfalls vor dem Schreiben in die Windows-Zwischenablage
+   geprüft. Jeder Paste liest den aktuellen Inhalt, einschließlich Änderungen
+   durch andere Anwendungen, und gibt ausschließlich den geprüften Snapshot
+   frei. Die zentrale Policy kann vertrauliche Inhalte und gefährliche
+   Ausführungsbefehle sperren. Änderungen von Ziel, Auswahl oder Policy während
+   eines asynchronen Scans dürfen keinen ungeprüften Inhalt freigeben.
+   Erlaubter öffentlicher Text funktioniert in normalen Eingabefeldern und den
+   im MVP getesteten Web-Editoren unabhängig von Website oder Anwendung
+   (Notizen, Webmail, Chat und KI). Vertraulicher Text wird blockiert. Anschließender
+   Versand, getippter Text und durch Seitenskripte erzeugte Request-Bodies werden
+   zusätzlich geprüft; Paste-Prüfung allein reicht nicht.
+3. Gewöhnliche Windows-Dateiuploads per Dateiauswahl und Drag-and-drop werden
+   anhand der tatsächlich übertragenen Bytes geprüft. Lokale Klassifikation,
+   Fingerprints, semantische Erkennung und erforderliches OCR bleiben lokal.
+   Änderung nach dem Scan darf keine ungeprüften Bytes freigeben.
+4. Verschlüsselte, übergroße oder unvollständig geprüfte Dateien sowie nicht
+   unterstützte Transferwege werden mit verständlichem Grund blockiert.
+   Fehler, Scanner-Ausfall, abgelaufene Policy und Widerruf dürfen keine
+   Freigabe vertraulicher Inhalte verursachen. Alternative Netzwerkwege dürfen
+   die erzwungene DLP-Prüfung nicht umgehen.
+5. Echte Windows-/Electron-Tests prüfen für jeden unterstützten Kernweg sowohl
+   erlaubte Übertragung als auch vertrauliche Inhalte. Ein kontrollierter
+   Empfänger beweist, dass blockierte Inhalte nicht angekommen sind. Die Tests
+   schließen Policywechsel, Tab-/Frame-Wechsel und Scannerfehler ein.
+6. Block-/Allow-Entscheidungen sind für den Administrator nachvollziehbar.
+   Debug-Traces korrelieren Prüfung und Freigabe, zeigen Laufzeiten und Fehler;
+   Passwörter und Tokens gelangen nicht in gewöhnliche Logs. Zentraler
+   Diagnostikschalter verändert keine DLP-Entscheidung.
+7. Ein reproduzierbarer Windows-Build enthält exakt den geprüften Code und die
+   lokalen Scanner-Runtimes. Enrollment, Policy-Sync, mehrere Tabs, wiederholte
+   Uploads/Paste und Neustart bestehen einen dokumentierten Stabilitätslauf.
+   Keine offene kritische Umgehung oder Regression auf diesen Kernwegen.
+
+## Aktueller Abnahmestand
+
+749 Tests bestehen im letzten vollständigen Lauf; ESLint verlangt null Fehler
+und null Warnungen. Nachweis: `artifacts/mvp-final-startup-suite.log`.
+Die neue native Windows-Abnahme besteht mit 17 Checks, einschließlich echtem
+Maus-Klick im contenteditable-Editor, Klartext/HTML-Clipboard, Policy-Race,
+YARA-/ICAP-Block und Scanner-Ausfall. Danach startete ein anderer Browserprozess
+mit demselben DPAPI-Profil, Gerät und Policy v4, ohne erneutes Enrollment.
+Fünf weitere Neustart-Checks bestehen: insgesamt 13 erlaubte Requests,
+null vertrauliche Requests und zwei exakt übertragene öffentliche Dateien.
+Beide Prozesse exportierten korrelierte Clipboard-, URL- und Upload-Traces
+mit null Exportfehlern. Nachweise: `artifacts/windows-dlp-mvp-process-restart-summary.json`,
+`windows-dlp-mvp-first-process-native-proof.json` und
+`windows-dlp-mvp-restart-native-proof.json`.
+Der aktuelle integrierte Relay-/Proxy-/Preload-Stand bestand diese native
+Abnahme erneut: `artifacts/windows-dlp-mvp-current-frozen-native.log`.
+
+Das Gateway prüft normalisierte Textdarstellungen einzeln und revalidiert
+Policy/Widerruf vor Versand und Ausgabe. Tatsächliche ICAP-/Provider-Tests
+blockieren auch codierte Scanner-Marker vor dem Anbieter. Begrenzte
+Normalisierung ist kein universeller Deobfuskationsnachweis.
+
+Ein Windows-Build ist abgeschlossen, einschließlich tatsächlicher
+Fuse-Werte, eingebettetem ASAR-Header-Hash und Parser-ACL-Provisionierung.
+Paket-/Runtime-Vergleich bestanden. Der korrigierte CLI-Inspector-Test und die
+manipulierte ASAR-Kopie wurden danach tatsächlich negativ geprüft; die Kopie
+wurde vor Anwendungseinstieg abgewiesen. Eine weitere unabhängige Prüfung fand
+akzeptierte Zertifikats-/Feature-Bypass-Startparameter. Der Quellstand verweigert
+diese inzwischen mit terminalem, festem Fehler. Der erneute Build, vollständige
+Paketprüfung und elf zusätzliche negative Startfälle bestehen am tatsächlichen
+Paket. Nachweis: `artifacts/package-fuses-proof.json`, einschließlich
+`unsafeStartupOverridesRejected=true`. Der Installer bleibt `NotSigned`.
+WebTransport ist inzwischen als tatsächlicher Umgehungsweg bestätigt:
+HTTP-DLP-Hooks und Abschalt-Flags verhinderten die Übertragung nicht. Ein nativer
+Proxy-Zwang wurde dagegen mit null empfangenen Paketen bei weiter funktionierendem
+HTTP bewiesen. Der authentifizierte lokale Relay ist inzwischen in Enrollment,
+Policywechsel und Quarantäne integriert; Browserverkehr erhält keinen DIRECT-
+Fallback. Enterprise-Proxy-Zugangsdaten sind an Host und Port gebunden.
+Die vollständige Browser-Abnahme mit echtem WebTransport-Empfänger besteht:
+Eine ungeschützte Window-/Worker-Kontrolle übertrug 132 Bytes; der tatsächlich
+enrollte Browser übertrug null Pakete und Bytes, auch nach reviewed DIRECT und
+HTTPS-PAC→DIRECT-Policywechseln. Drei gewöhnliche HTTPS-POSTs funktionierten.
+Nachweis: `artifacts/fullmain-webtransport-native-proof.json`, mit genauen
+Quellhashes; spätere Änderungen betreffen ausschließlich Startparameterprüfung.
+Die vor HTTP blockierten Versuche liefern keine webRequest-Callbacks und
+damit weiterhin keine einzelnen DLP-Audit-Ereignisse. Diese SIEM-Grenze bleibt offen.
+Ältere fehlgeschlagene Testläufe bleiben als solche erhalten.
+
+## Verbleibende Abnahmen
+
+Die lokale semantische Browser-Abnahme ist jetzt bestanden: reviewed Teaching
+behält 36 Fragment-Fingerprints und Prüfmetadaten, keinen Originaltext. Mit
+dem tatsächlichen gepinnten Modell wurden öffentliche Inhalte erlaubt und eine
+nichtliteral vertrauliche Paraphrase bei Paste, Textversand und Dateiupload
+blockiert. Drei öffentliche Requests und null vertrauliche Paraphrasen erreichten
+den Empfänger; eine öffentliche Datei kam exakt an. Nachweise:
+`artifacts/windows-semantic-dlp-native-proof.json` und
+`artifacts/windows-semantic-teaching-proof.json`.
+
+Neue Stabilitätsgrenze: Chromium 152 kann bei WebRTC in einem initialen
+about:blank-Iframe unter der nativen Connection-Allowlist den Renderer beenden.
+Der zusätzliche Frame-Preload verhindert entsprechende Konstruktoraufrufe in
+srcdoc-, Blob- und Cross-Origin-Frames; initiales about:blank erhält diesen
+Preload jedoch nicht. Diese verbleibende Grenze ist kein bestandener
+All-Frame-Nachweis. Eine weitere native oder frühere Absicherung ist vor der
+entsprechenden Stabilitätsabnahme erforderlich. Der zugehörige Chromium-Fix
+ist Commit `46fcf3faed9db394de7046a100301f64c2842f0e`; auch die isoliert
+getestete Electron-Nightly vom 13. Oktober enthält ihn noch nicht. Ein bloßes
+Versionsupdate oder JavaScript-Wrapper gilt daher nicht als Lösung.
+Ein kontextangepasster [Backport](native-runtime/README.md) besteht
+`git apply --check` gegen die genaue Chromium-Basis; er ist noch nicht kompiliert
+oder nativ abgenommen.
+
+- Aktuelle native Abnahmen zusammenführen und gegen den aktuellen Quellstand
+  erneut prüfen; ältere grüne Tests belegen keinen später geänderten Build.
+- Praktische Paste-/Versand-Coverage weiterer moderner Editoren prüfen.
+  Einfache contenteditable-Textpfade sind nativ mit erlaubtem Text, vertraulichem
+  Text und inert eingefügtem HTML geprüft. Komplexer Richtext und undurchsichtige
+  Clipboard-Formate bleiben konservativ gesperrt; universelle Editor-Kompatibilität
+  ist damit nicht belegt.
+- Nicht unterstützte Hintergrund-/Streaming-/WebSocket-/WebRTC-Pfade auf
+  tatsächliche Sperre prüfen; umfassende Worker-Unterstützung ist kein MVP-Ziel.
+- Race-, Timeout-, Policywechsel- und Scannerfehler-Nachweise vervollständigen.
+- Abschließende vollständige Tests, native DLP-Abnahme, Stabilitätslauf,
+  Windows-Build und Paketprüfung durchführen und Ergebnisse dokumentieren.
+
+Die Liste ist ein Arbeitsauftrag, keine Behauptung, dass jeder Punkt bereits
+fehlt oder ein bestätigter Bypass besteht. Der folgende Audit bestimmt die
+konkreten Defekte und fehlenden Nachweise.
+
+## Verschoben
+
+## WebSocket- und WebRTC-Ziel
+
+Nutzerpräzisierung: WebSockets und WebRTC sollen nutzbar sein, wenn ihr jeweiliger
+Datenweg überprüfbar ist. Pauschale Sperre ist eine vorläufige Schutzmaßnahme,
+kein funktionales Endziel. Freigabe muss pro überprüfbarem Kanal erfolgen:
+WebSocket-Nachrichten einschließlich binärer/komprimierter Nutzlasten und
+WebRTC-DataChannels benötigen Inhaltsprüfung vor Übertragung sowie aktuelle
+Policy- und Zielbindung. WebRTC-Audio/Video benötigen eigene Medienregeln und
+Prüfnachweise; eine Signalisierungs- oder Domainprüfung belegt keine Inhalts-DLP.
+
+Die vorhandenen Electron-webRequest-Hooks prüfen HTTP-Anfragen und den
+WebSocket-Verbindungsaufbau, liefern jedoch keinen allgemeinen nativen Gate für
+jede WebSocket-Nachricht oder WebRTC-Nutzlast. Ein JavaScript-Wrapper allein ist
+keine belastbare Sicherheitsgrenze. Unterstützte Wege benötigen einen
+kontrollierten Transport oder zusätzliche native Chromium-Enforcement-Hooks
+mit echten Nachrichten-/Empfänger- und Umgehungstests. Bis dahin bleibt nur der
+nicht überprüfbare Weg gesperrt, mit dokumentiertem Kompatibilitätsgrund.
+
+## Weitere Roadmap
+
+Andere Betriebssysteme und Mobile, vollständige KI-Agentensteuerung und eigene
+Worker-Sitzungen, weitere Komfort-/Designfunktionen, zusätzliche Vault-Funktionen,
+breitere Multimediaanalyse und zusätzliche Admin-Erweiterungen sind Roadmap.
+Bestehender Code bleibt erhalten, wird aber nicht zur Voraussetzung dieser
+MVP-Abnahme erweitert.
+
+Produktionsrollout bleibt von Pilot-/MVP-Abnahme getrennt: signierter Installer
+und Updatekanal, unabhängige Sicherheitsprüfung sowie kundenspezifische IdP-,
+Proxy-/ICAP-/SIEM-Integration benötigen eigene Nachweise. Das MVP verspricht
+keine universelle Erkennung aller Geheimnisse und keinen Schutz gegen einen
+Angreifer mit lokalen Administratorrechten.

-# Native worker ownership: verified boundary and next implementation
+# Attributed agent background workers
 
-Current individual-agent mode blocks requests without a guarded native tab owner. This deliberately prevents service workers from borrowing an actor's authority through origin, Referer, renderer messages or a guessed tab. It also limits compatibility with worker-dependent applications.
+The central `browser.allowAgentBackgroundWorkers` gate defaults false. The
+permission-only `network:background` scope is also explicit in both the agent
+baseline and individual grant; it is not a callable agent RPC. User profiles can
+inherit or deny this feature (`features.agentBackgroundWorkers`); they cannot
+allow it beyond baseline or grant. Applicable denials accumulate.
 
-## Native evidence
+Development support is restricted to immutable, nonpersistent native browser
+partitions owned by the enrolled device, individual principal and credential
+generation. Human/default shared partitions, legacy callers and unattributed
+worker traffic remain blocked. Enabling this feature is not general human browser
+worker compatibility, persistence or cross-device worker roaming.
 
-A local Windows feasibility experiment used Electron 44.7.0 / Chromium 152.0.7977.130, two independent in-memory native sessions, and the same synthetic loopback origin. Each session registered a service worker and initiated a POST from that worker. Each session's native webRequest listener received only its own request.
+Before network release the owner registry must prove the worker's partition,
+registration/source and native context; current policy, grant generation/expiry,
+destination and DLP remain mandatory. The foreground tab or a renderer-provided
+identity cannot establish ownership. Revocation must deny existing worker traffic,
+not merely prevent new registrations. No cloud inspection or extra worker scope
+bypasses local mandatory inspection.
 
-The worker requests had no webContentsId or requesting frame. Both had the same initiator origin. Their request objects carried no worker version ID or process ID. ServiceWorkers.getAllRunning exposed different renderProcessIds, but those identifiers were absent from webRequest events. Runtime worker version IDs were available as dictionary keys; the worker information values omitted the versionId field advertised in the installed type definition.
+## Verification status
 
-Local ignored evidence: `artifacts/worker-partition-feasibility.json` and `.log`. This isolated API experiment did not run production browser guards or establish an OpenTelemetry integration proof.
+The current real Electron admin workflow exercised typed login-rule editing,
+independent signed publication and auditor read-only access. All 193 completed
+API requests had exported traces; one canceled read had no failed mutation.
+The collector reported zero rejected writes. Trace examples:
+`a0f881d3c99650c53bacf547a191b216` and
+`4416533c41ffe3e2adb81af46a30e0d4`.
 
-Electron documents native [webRequest events](https://www.electronjs.org/docs/latest/api/web-request), [service-worker inventory](https://www.electronjs.org/docs/latest/api/service-workers), and [session partitions](https://www.electronjs.org/docs/latest/api/session). The installed `node_modules/electron/electron.d.ts` was checked against the actual runtime.
+Focused policy tests verify the disabled default, preservation through signed
+publication, strict boolean validation and rejection of `network:background`
+as an executable RPC. Eleven registry tests cover immutable ownership,
+installation-before-network-use, revocation and retryable failed cleanup.
 
-## Defensible design
+The central gate/scope controls start unchecked, and profile schema/enforcement
+prove inherit/deny-only behavior. The actual Windows/Electron admin fixture also verifies the worker gate/scope
+start off, auditor controls are disabled, and typed login-rule creation goes
+through exact signed independent review and policy-history restoration. Its 193
+completed API requests export parent-correlated spans; one canceled GET during
+identity reload is recorded separately, with no failed mutation. See
+`artifacts/agent-grants-history-admin-proof.json`,
+`artifacts/agent-grants-history-admin-traces.json` and
+`artifacts/credential-submission-admin-controls.png`.
 
-Allocate a separate native session for each immutable device/principal/generation identity. Assign ownership in the main process before creating any native tab or initiating a request. Install the full network, DLP, download, permission, proxy, DNS and preload controls before the partition is used. A worker's owning principal then comes from the listener's native session closure, not page-supplied claims.
-
-Never reassign a partition to another actor or newer generation. Check the current signed grant, device status, policy expiry and destination scopes before inspection, after every awaited stage and immediately before release. Revocation must quarantine the owner's partition and close its connections. Cookies and authentication state should remain isolated unless a separate explicitly authorized sharing design is implemented.
-
-This attributes requests to a principal, not to a specific tab. Shared workers can serve multiple tabs, and service workers may outlive their clients. Any operation requiring an unavailable tab, exact document or visual approval must remain blocked until an independently verified context is available. Worker downloads, immutable streamed request-body inspection, background lifetimes, restart ownership and complete revocation behavior need native proofs.
-
-## Migration surface
-
-The current main process uses one `browserSession` for proxy updates, DNS resolution, permission handlers, upload terminal events, download fetching and will-download, webRequest gates, developer-tools frontends, preload registration, native tab construction, revocation cleanup and VPN quarantine. All relevant uses must become session-aware together. Merely selecting a new session for a tab while leaving these controls global would create an enforcement gap.
+Runtime owner-registry migration, actual native worker attribution/revocation
+tests, runtime traces and final Windows/package proof are pending. Do not claim worker support solely from a stored policy flag.
