 The dedicated branch is `integration/plugin-native-acceptance`. Its Draft PR

+# Plugin model transport cold start
+
+Commit `092438803bed96753bfe68cb78da9ca1137dee25` removes an independent startup
+dependency on the internal AI sidebar. It does not establish the cause or outcome
+of the original native failure; that still requires an authorized native retest.
+
+## Reproduced boundary
+
+At native candidate `677aac33b1eec9dbd4a367417a49c964cdea63e7`, the plugin model
+selector reads the saved host provider, while main's provider registry starts
+empty. The existing sidebar synchronizes that registry when visible or sending.
+The plugin startup path did not. A nondefault configured loopback port can
+therefore fail main's provider allowlist before HTTP transport starts.
+
+The revised `components/PluginAIContextHost.test.tsx` installs the browser sample,
+mounts the trusted host component, uses the real application preload, and routes
+model requests through `registerProviderHandlers` and its actual allowlist. It
+does not mount the internal sidebar or manually alter the allowlist. Credential
+injection uses synthetic fixture markers; the HTTP edge and deterministic local
+fixture use the existing transport. No paid service, real key, Note, or host is
+used. This remains DOM/in-process evidence, not native sandbox acceptance.
+
+Failed-before evidence is `/tmp/netcatty-ai-cold-provider-before-final.log`:
+
+```text
+ok: false
+allowlistRejected: true
+statusCode: undefined
+```
+
+The corrected regression passes and preserves both the selected fixture provider
+and a second host-configured synthetic provider. It checks that provider markers
+and configuration do not enter plugin-facing model/context envelopes. Expected
+SDK error output is suppressed during this diagnostic so request payloads and
+headers are not logged.
+
+## Correction
+
+Before publishing a selected model handle, the trusted renderer synchronizes the
+current host-owned provider settings through the existing `aiSyncProviders`
+application API. It checks that the selected model revision matches the snapshot
+being synchronized. The runtime rechecks activity, cancellation, model revision,
+and pending-selection ownership after the await. Pending selections count toward
+the model-handle cap; release and shutdown invalidate late results.
+
+Plugin requests supply no URL, credential, or provider configuration. The existing
+main sender validation, endpoint allowlist, source binding, and model invocation
+budgets are unchanged. No new schema feature, plugin permission, or consent
+dialog is added. The assistant package is unchanged and retains SHA-256
+`c7d784d5c3bd2feb463afd58eae3a9594615395b168174cb8a3d0677584ae395`.
+
+Production integration touches `configuredModel.ts`, `trustedHostRuntime.ts`, and
+`usePluginAIContextHost.ts`. The hook's import and `prepareModel` option may
+overlap host-selection work; preserve both when integrating the separate policy
+task. Permission-engine, consent-dialog, and sample-UI changes are outside this
+correction.
+
+## Native and policy status
+
+The native open/close sidebar comparison was incomplete. Execution auto-review
+denied the Application-scope `context.selected.list` grant; that action did not
+execute. No post-sidebar inference was performed, the prompt expired, and the
+sample was disabled while the worker cleaned up. This is not native confirmation
+of the startup cause. The original `677aac33` app remains frozen for comparison;
+this fix does not authorize retrying the denied execution action.
+
+In the earlier permission engine, **Application** grants are memory-only for the
+application lifetime; **Always** grants are persisted. An explicitly authorized
+Application grant can fit bounded temporary QA. A one-use prompt on every stream
+read is not an unavoidable target UX. The separate policy task implements the
+new direction: default Allow for declared supported capabilities, per-plugin
+Allow/Ask/Deny settings, audit, and in-app Ask dialogs. That product change is
+separate from execution-tool authorization and must not be used to evade a tool
+denial. This transport correction does not redesign that policy.
+
+Native outcome, independent verification, and the sample's light-theme appearance
+follow-up remain separate acceptance work. No GUI launch, sandbox bypass, paid
+model invocation, main merge, or release was performed for this correction.
+
+## Node 22 CI observer correction
+
+The new cold-start test failed on exact head `9ca70f329` in test run
+`40436198585`, Linux job `121965743101`: 15,206 passed, 1 failed, 50 skipped.
+The sole failure was the empty SDK/renderer-error assertion receiving one
+`SDK_OR_RENDERER_ERROR` marker. This red result is retained as evidence; it is
+not an unrelated baseline failure.
+
+The CI runtime was Node `22.23.3`; local validation had used Node `24.19.0`.
+Reproduction on the exact CI version identified the safe category
+`setup:node-sqlite-experimental`, before any model operation. The existing
+`node:sqlite` import schedules its ExperimentalWarning on the next tick via
+`console.error`. The newly added observer was installed before that warning
+drained. The same test passed on Node 24, which did not emit that warning.
+
+The test now lets pending module warnings reach normal stderr before installing
+the SDK/renderer observer. The warning remains visible, and the zero-runtime-error
+assertion is unchanged. Safe phase/error categories make future failures
+diagnosable without request payloads or headers. No production behavior, timeout,
+permission, or cancellation assertion changed. Both Node versions pass the
+focused test; the Node 22 parallel fixture/UI/provider/preload group passes all
+16 tests with concurrency 4.
+
+Diagnostic evidence: `/tmp/netcatty-ai-cold-ci-node22-sqlite-category.log` fails
+before correction, `/tmp/netcatty-ai-cold-ci-node22-after.log` passes with the
+SQLite warning still visible, and `/tmp/netcatty-ai-cold-ci-node22-parallel.log`

+# Managed-window Ask acceptance candidate
+
+The dedicated branch is `integration/plugin-ask-routing-acceptance`. Its Draft
+PR records the exact frozen integration head, CI and private renderer artifact
+handoff. It starts from frozen #4001 at
+`02049102b6732778adcd0f33b0a0ade6b4752327`; the old source checkout, QA workspace,
+profile and renderer artifact remain unchanged.
+
+## Exact inputs and ownership
+
+The only new input is policy owner's reviewed Ask correction
+`89beeb93749c751f255beb6d0e0f95d23bdd9a7b`, imported by ordinary merge
+`1b21c41fa26c0173084c7ae75e640ef3274285dd`. There were no merge conflicts or
+manual production edits. These seven production files exactly match that input:
+
+| File | Owned production delta |
+| --- | --- |
+| `electron/bridges/windowManager.cjs` | Enumerate managed app windows, including Settings |
+| `electron/main/registerBridges.cjs` | Supply the managed permission-window getter |
+| `electron/plugins/hostService.cjs` | Pass that getter to the existing decision host |
+| `electron/plugins/permissionDecisionHost.cjs` | Bind ready/focused/visible/unlocked managed renderer selection and request lifecycle to the chosen receiver |
+| `electron/plugins/pluginBridge.cjs` | Guard permission readiness/replies by managed app window and main frame; reject plugin/foreign/subframe senders |
+| `components/SettingsPage.tsx` | Mount the existing permission host for standalone Settings |
+| `components/plugins/PluginPermissionHost.tsx` | Mark Ask with the existing host-security surface so attached native views yield |
+
+The input also owns the Settings-installed-entrypoint regression, renderer test
+updates and policy/security documentation. AI d33 startup wiring, sample assets,
+the combined cold-start assertions and all earlier policy/transport history are
+preserved from 020. `ModelSelector.tsx` is unchanged from 020; the separate
+model-selector failure-loop repair is not imported. Diagnostic #3999 remains
+excluded. No broker resource/source rules, stream restrictions, package/lock
+inputs, native dependencies or sandbox configuration change in this integration.
+
+## Frozen 020 native evidence
+
+The parent closed that QA session and released the GUI. Its partial outcome is:
+
+| Native case on 020 | Result |
+| --- | --- |
+| Default Allow cold Send and completion | Passed |
+| Stop, AI Deny, restore without automatic replay | Passed |
+| Themes in new views | Passed |
+| Ask visible dialog | Failed: no visible dialog, timeout, zero new model requests |
+| Ask acceptance/cancel and content-read matrix | Not run; remain pending |
+
+The input's independent source-only delta review is scoped clean. Its installed
+SDK/registered IPC test reproduces the old Settings-owned failure and passes with
+the correction using represented Electron objects. That is not native Ask
+success. No new native acceptance is claimed by this coding executor.
+
+Earlier terminal solo/split core passes with corrected fixtures, unreliable/
+unverified Focus and one QA Enter in A during a palette attempt remain historical
+evidence. There is no global zero-input or full terminal native-pass claim. The
+old Rfam run failed socket transport before connect resolved, without reaching
+authentication/SELECT; its cause and auth/TLS compatibility remain unverified.
+The next native priority is the new Ask path, not more old-baseline loops.
+
+## Checks and retained CI history
+
+| Local check | Result |
+| --- | --- |
+| Registered runtime | 696 tests: 695 passed, one native skip, zero failed/cancelled |
+| Contract/SDK/CLI | 91 passed |
+| Offline examples | Five passed, one Docker opt-in skip |
+| Mounted cold-start AI/permission/selected-summary/Host group | 21 passed |
+| Settings and security-surface visibility group | 37 passed |
+| Contract/capability/Codex generation and drift | Clean |
+| Lint | Zero errors, seven existing warnings |
+| Five sample archives | Validated; two builds each are identical and match frozen 020 |
+
+The exact integration production build, renderer inventory and final CI are
+recorded in the Draft PR and artifact provenance. Local native packaging and
+unpackaged GUI acceptance are not claimed. This environment uses locked
+dependencies and standard patches; the official pinned Electron binary uses its
+documented cache/proxy support. No header workaround, native shim, HOME change
+or sandbox change is introduced.
+
+Input89 [test CI 40453446775](https://github.com/binaricat/Netcatty/actions/runs/40453446775)
+succeeded on the parent's single infrastructure-only rerun: 15,342 passed, 50
+skipped, zero failed/cancelled. The original runner interruption remains evidence;
+this worker did not duplicate its retry. Input89
+[four-platform packages](https://github.com/binaricat/Netcatty/actions/runs/40453446781)
+passed with release jobs skipped. Frozen 020's successful full/platform CI and
+all earlier diagnosed/unexplained failures remain separate predecessor evidence.
+
+The [sample manifest](ask-routing-packages.json) records exact IDs, versions,
+features, permissions/resources and archive/content hashes. All five archives
+are byte-identical to 020, including Assistant
+`7943d4c3800914fe0acd3d0f3a3d7f7c1910c212a5dc58a044871a6a82485274`.
+No archive was activated by this executor. Its unchanged owner README retains
+old review wording; the current Allow/Ask/Deny procedure governs acceptance.
+
+## Production-renderer preparation and native Ask recipe
+
+1. Create a new isolated checkout at this Draft's exact head and a separate
+   disposable synthetic QA profile. Keep the old 020 workspace/profile intact.
+2. Match `package.json` and `package-lock.json` hashes to the renderer artifact's
+   provenance and the independently normally rebuilt native dependencies. They
+   are unchanged from 020. Prepare matching host workspace packages normally.
+   **The complete backend checkout must match the new head:** the frontend-only
+   bundle does not include the new CJS window-routing code or native binaries.
+3. Materialize the exact private Library file/version in the consumer's own
+   environment. Verify its archive SHA-256 and every dist file with the supplied
+   inventory/verification script. Producer-local paths are not portable.
+4. Use those verified production assets as a whole `dist/` in the matching
+   checkout, with the ordinary Electron entrypoint, no Vite environment and
+   normal sandbox/helper settings. This is native **unpackaged production-
+   renderer QA**, not packaged-binary certification. Process-loss causality
+   remains unclassified; no native build/header workaround is supplied.
+5. Recreate only the synthetic provider/Note/sample setup. Verify Default Allow
+   remains functional; then set the plugin operation to Ask in the active main
+   or standalone Settings window. Keep the selected receiver visible, focused,
+   ready and unlocked; opening Ask must not force focus back to main.
+6. Record visible readable Ask and native-view yielding. Check cancellation and
+   acceptance as separate explicit operations: cancel must send no model request;
+   accept must authorize only the current bounded operation. Complete the
+   content-read Allow/Ask/Deny matrix and lifecycle invalidation cases. Do not
+   treat the earlier zero-request timeout as an Ask pass.
+7. Record exact head, archive/sample hashes, request counters, prompt ownership,
+   screenshots/video and any unrun cases. Report a model-selector failure
+   separately rather than folding its other owner's repair into this candidate.
+
+Hosting/distribution/deployment and remaining DB/terminal acceptance gates stay
+parent-coordinated. No main merge, Ready transition or release is part of this
+handoff.

+## Official maintenance
+
+The borderless gold pill means that the Netcatty project maintains the plugin.
+It does not certify the plugin's safety or grant permissions. It is separate
+from the official marketplace source label.
+
+The main process requires the built-in official source and one of these explicit
+first-party ID and repository pairs:
+
+- `com.netcatty.starter`, `binaricat/Netcatty`
+- `com.netcatty.hello`, `binaricat/Netcatty`
+
+A local import, a third-party copy, an ID prefix, author text, manifest publisher,
+README, or membership in the official marketplace cannot create this badge.
+The renderer consumes the host result through the existing trusted-app IPC
+boundary. No new plugin permission or plugin RPC is introduced.
+
+## Validation scope
+
+Focused registered tests cover source spoofing, exact installed identity,
+hash-bound images, invalid metadata and decoding, redirects, source removal,
+selection changes, cache reuse, lazy loading, stale UI cleanup, placeholders,
+and borderless light/dark theme classes. These tests do not establish native
+layout, actual account identity, live CDN deployment, or successful network access.
+Actual app screenshots and native acceptance remain separately scheduled.

+Draft #4011 is the single landing vehicle for the accumulated plugin foundation.
+Earlier integration records describe frozen evidence, not the current acceptance
+status. This candidate preserves their source history through ordinary merges.
+The user cancelled the reference-driven row redesign. Installed grid and Settings
+quick-toggle layout are restored exactly to b14, while author presentation and all
+functional/security corrections remain. Cancelled visual commits stay in history
+with attributable reverts; they are not effective changes in the landing tree.

+or terminal diagnostic #3999. No older source PR is closed by this preparation.

+
+The separately published icon branch first reverted its outline correction
+(`530ff0318`), then the e4 row commit (`6e4465f47`). Neither outline correction nor
+those isolated reverts are imported here; foundation never included the outline.
+The e4 and 1f renderer artifacts are historical pre-cancellation evidence, not
+accepted final UI. No further cancelled-design build or screenshot is requested.
+
+The only manual merge conflict was the end of `index.css`. Resolution retains
+both the prior host-security theme block and main's window-background-blur block,
+with their declarations unchanged. Automatic combinations retain main appearance
+wiring alongside plugin settings/theme wiring, all five locales, preload methods,
+the host services and SDK exports. No permission, source, endpoint, sandbox or
+selected-resource restriction is relaxed. Package and lock inputs are unchanged.
+
+`50fda9142` reuses the same selection-token comparison after an install-triggered
+catalog refresh, including an install rejected for a changed/withdrawn selection.
+The rejection is preserved; mounted authors no longer retain withdrawn enrichment.
+The regression makes no package download or execution. It also preserves the
+original synchronous unavailable-source rejection in `list()`: the first aggregate
+runtime run caught that b14 changed it into a Promise rejection. The assertion was
+not weakened. Corrected aggregate runtime: 711 pass, one native skip, zero failures
+or cancellations. The original failed run and fail-before regression are retained.
+
+## Checks and packages
+
+Registered runtime, SDK/contract, Settings and actual connected host entrypoints,
+changed-main MCP/appearance/editor regressions, example preparation, code generation,
+lint and the normal production renderer build are run on this candidate. Exact
+head, commands, counts and CI links are recorded in #4011. Package provenance is
+in [the bounded sample manifest](foundation-packages.json): each archive is built
+twice and whole-byte compared. Assistant is byte-identical to d40; Host changes
+only README wording, with manifest/entrypoint unchanged. Database-owned, Rfam and
+terminal archives change only `browser.js` minified bound identifier spelling.
+Rebuilding the same sources with d40's generated SDK/contract artifacts reproduces
+the exact old archive hashes. Parsing and normalizing lexical bindings yields
+identical ASTs for all three bundles; manifests, protocol and permissions do not
+change. Preparation does not connect, activate or query.
+
+Local checks at pre-restoration1f: runtime 711 pass/one existing native skip; SDK91; Settings and
+connected host/security78; changed-main MCP/appearance/editor71; examples five
+pass/one Docker opt-in skip. Contract/capability/Codex generation has no drift;
+lint zero errors/seven existing warnings; normal production build36.13s. These
+checks do not claim native UI, packaging or encrypted transport acceptance.
+Restoration-focused layout/author tests: six pass; changed-file lint and diff
+checks clean. Two broader Settings runs each had38pass/one PluginLogSettings
+file-entry failure, without a detailed assertion; that file alone passed. Their
+cause remains unclassified and both failed runs are retained. No production log
+change or baseline attribution is made. Every one of the six layout paths exactly matches b14; fourteen functional
+paths (identity/provenance, permissions, directory availability and sync included)
+remain byte-identical to1f. The five sample records remain unchanged. Pre-restoration1f exact CI completed:
+[test40505644082](https://github.com/binaricat/Netcatty/actions/runs/40505644082)
+records15,372pass/50skip/zero failures or cancellations on its successful retry;
+[packages40505644200](https://github.com/binaricat/Netcatty/actions/runs/40505644200)
+passed all four platforms with release skipped. Its original runner shutdown is
+retained. These results do not certify the restored head.
+
+An earlier coding-executor full suite timed out after 15 minutes: 31 failures and
+482 cancellations. Seven failures reproduced on unchanged d40; 24 were not probed
+on that baseline. They remain unresolved evidence, not assumed baseline failures.
+No additional long local full suite is used to conceal them. Clean-run exact-head
+CI is a separate aggregate check and does not diagnose that historical run.
+
+## Acceptance and landing order
+
+1. Foundation: keep #4011 Draft until integrated CI/review and affected native UI
+   acceptance settle. d40 Settings, Host/Vault policy, terminal A/B selection and
+   inert multiline draft isolation, and native chat split/drag ownership passes
+   are historical evidence at their stated heads. They do not certify this new
+   current-main merge tree. The e4/07b reference-driven row design is cancelled;
+   stop its native visual work. Restored layout retains author/avatar presentation.
+   Avatar/catalog behavior and the final install-refresh correction still require
+   their scoped review/acceptance; cancellation does not erase functional gates.
+2. Marketplace distribution: retain static-source identity and v2 delivery checks,
+   but track reviewed registry data, actual hosting/CDN and install/update/source
+   replacement/withdrawal acceptance separately. Current live source-only viewing
+   is not installation or deployment acceptance. Never weaken admitted-source or
+   destination guards to manufacture a pass.
+3. Global Agent: #4006/#4012 remain a separate later increment, with their own
+   scope, review, CI and actual sample smoke. #4002 is also separate.
+
+Historical integration vehicles #3967/#3989/#3993/#3997/#4001/#4004 are superseded
+as landing vehicles, not discarded contributions. Their ancestors and native
+receipts stay available. Unique source PRs remain intact; no premature closures.
+
+Directory enumeration is intentionally unavailable in the default production
+composition until a same-handle adapter exists. The advertised feature now tells
+SDK callers the truth; filesystem permission alone does not enable it. The new
+sync composition test proves local collect/apply/hydrate with real databases, not
+encrypted cloud transport or native cloud-account sync. A native compatibility
+transition needs two properly versioned builds; two 0.0.0 checkouts do not qualify.
+
+Public database acceptance remains blocked by the retained TCP refusal before
+protocol payload; the separately owned local fixture is pending. Source-policy,
+compatibility and database gates must be explicitly reconciled by the parent,
+not silently removed from requirements. Nested log-dialog overlap has source
+coverage but no normal native route in the tested UI. This is code-readiness work,
+not a claim that deployment, every original requirement or the whole project is
+complete. No main merge, Ready transition, release or live metadata publication.

+
+Diagnostic #3999 and its tests/docs-only `3fdaa357` continuation are not merged.
+No terminal runtime fix is required by the fixture-classification finding.
+Database protocol and fixed SQL remain solely in the minimal examples.
+
+## Direct integration decisions
+
+The initial merge conflict was `components/PluginAIContextHost.test.tsx`. The
+combined test keeps policy's absence of a second native content-sharing review
+and AI's actual main allowlist, two-provider synchronization, streamed result,
+Stop/lock cleanup and empty SDK-error assertion. The Node 22 warning drain is
+retained. The obsolete forced-review cancellation branch is superseded by the
+current in-app Ask/cancellation tests; no transport assertion is dropped.
+
+No production file needed a manual conflict resolution. Policy production files
+remain identical to the policy input; the three AI startup wiring files and
+sample assets remain identical to d33c0193. The stream service/router and prior
+terminal renderer eligibility/publication files are unchanged from frozen 677.
+
+Integration commit `7d8a354404d68071d0924532ffe74c713ace6cb9` updates two stale
+disclosure assertions in `PluginPackageManager.test.tsx` and
+`PluginMarketplace.interaction.test.tsx`. They expected the old words
+`not a grant`; the new assertions require default Allow, Ask/Deny controls and
+retained host validation/resource scope. Existing escaping, advanced-authority,
+source and README-failure assertions remain intact. Production copy is unchanged.
+
+The later authoritative 79a9bd6 policy merge overlapped those two tests. Their
+final contents are byte-identical to 79a9bd6: all three earlier policy assertions
+remain, together with the owner's additional unbounded-resource, sensitivity,
+escaping/source-order and advanced-authority checks. No assertion was dropped.
+This follow-up imports the owner's five-locale wording changes; it makes no
+manual production conflict edit and leaves the shared AI test intact.
+
+## Checks and retained failures
+
+| Local check | Result |
+| --- | --- |
+| Registered runtime | 695 tests: 694 passed, one native skip, zero failed/cancelled |
+| Contract/SDK/CLI | 91 passed |
+| Offline examples | Five passed, one explicit Docker opt-in skip |
+| Serial mounted AI/permission/selected-summary/Host/provider/panel group at 7856 | 31 passed |
+| Final settings, terminal interaction, cold-start host and locale group | 90 passed |
+| Contract/capability/Codex generation and drift | Passed |
+| Full lint | Zero errors, seven existing warnings |
+| Production build | Passed; Vite 35.50 seconds |
+| Five sample archives | Validated; repeat builds byte-identical |
+
+The initial settings group records 34 passes and two failures on the stale copy
+assertions. That run is retained separately from the corrected 36/36 result.
+
+Policy input [test CI 40443396430](https://github.com/binaricat/Netcatty/actions/runs/40443396430)
+first received an explicit runner shutdown. The parent requested one retry;
+this integration task did not duplicate it. Retry Linux job `121992430185`
+passed registered runtime (694/one skip) and examples (five/one skip), then
+failed those same two `not a grant` assertions: settings group 33 passed/two
+failed. It did not reach the full suite. The candidate includes the isolated
+test correction above; do not relabel the input CI as passing. Both input Windows
+jobs and [policy package CI](https://github.com/binaricat/Netcatty/actions/runs/40443396402)
+passed. Parent reports the independent policy correction reviews scoped clean,
+including both P2s and the three UI findings, with 71 focused/synthetic checks.
+
+The policy owner subsequently corrected these tests in predecessor
+`da4e80946d2f3fb48f205aae2a732252b2f51fca`. Its
+[test CI](https://github.com/binaricat/Netcatty/actions/runs/40444934631) passed
+15,342 cases with 50 skipped and no failures/cancellations, and its
+[four-platform package CI](https://github.com/binaricat/Netcatty/actions/runs/40444934738)
+passed. The final 79a9bd6 wording head's
+[test CI](https://github.com/binaricat/Netcatty/actions/runs/40446529092) passed;
+its [package workflow](https://github.com/binaricat/Netcatty/actions/runs/40446529100)
+is tracked separately in the Draft PR. No input retry was duplicated here.
+
+Integration predecessor `7856c664c3c2255a21badef2758bb29311b27a01` passed its
+[test CI](https://github.com/binaricat/Netcatty/actions/runs/40445809589): 15,344
+passed, 50 skipped, zero failed/cancelled, plus both Windows jobs and native
+automated checks. Its [four-platform packages](https://github.com/binaricat/Netcatty/actions/runs/40445809590)
+also passed. These are retained predecessor results; the new exact head needs
+its own aggregate CI.
+
+AI input [test CI](https://github.com/binaricat/Netcatty/actions/runs/40439111241)
+and [package CI](https://github.com/binaricat/Netcatty/actions/runs/40439111215)
+passed. Parent reports its three isolated changes scoped clean. Its prior 9ca
+Node 22 warning-observer failure remains documented in `ai-provider-startup.md`;
+the warning drain does not ignore errors or remove the empty-error assertion.
+Frozen 677's earlier unexplained MCP assertion remains separate history.
+
+This executor used locked dependencies with install scripts disabled, then the
+standard repository dependency patches. The official pinned Electron binary
+installed through its documented proxy support and executes in Node mode.
+No native-header download, alternate mirror, native shim, HOME change or
+sandbox change was used. Normal native postinstall/rebuild, local full-suite
+success and local desktop packaging are not claimed. Exact candidate CI is the
+aggregate full-suite and platform-packaging verification surface.
+
+## Exact packages and provenance
+
+The machine-readable [package record](policy-ai-packages.json) contains complete
+IDs, versions, required features, permission/resource declarations, archive and
+content hashes, and frozen-baseline comparisons. All five versions are 0.1.0.
+
+| Sample | SHA-256 | Comparison with frozen 677 |
+| --- | --- | --- |
+| Assistant | `7943d4c3800914fe0acd3d0f3a3d7f7c1910c212a5dc58a044871a6a82485274` | Matches the AI owner's new themed archive; only README.md, panel.css and panel.js differ from 677 |
+| Owned database | `f01c6a24382897d4b0bf4130941274abacb9a9a963f9b56ecaceb2c020f36874` | Byte-identical |
+| Rfam | `aaca586669db454e91d61487e576ed524d1b7190eed182bc2cd0035e59caa0d3` | Byte-identical |
+| Host actions | `cf04f82dfe25ab5cda6f5f3dad0a8fb06c37bedf9924f556bee2b8402e542ef2` | Byte-identical |
+| Terminal draft | `4c9c2388b7f891156192a0b5ab7b23291beba3555e7ec8cf24fbe2dfe1242d5e` | Byte-identical |
+
+After the authoritative 79 follow-up, all five archives were rebuilt twice,
+validated and compared byte for byte with the 7856 candidate: all five remain
+identical. No sample permission/resource declaration changed. The host's new policy changes
+effective authorization behavior; identical package bytes do not certify that
+new host behavior. The old Assistant c7d784d5 archive remains historical evidence,
+not the themed archive. No handoff archive was activated by this coding executor.
+The owner-identical Assistant README retains earlier permission-review wording;
+use this candidate's Allow/Ask/Deny procedure below for acceptance. That packaged
+copy is a documentation limitation, not a requirement for repeated dialogs.
+
+## Native preparation and remaining gates
+
+Use the exact candidate head from its Draft PR in a separate disposable native
+checkout/profile. Keep normal platform sandbox/helper settings. Build and hash:
+
+```sh
+npm ci
+npm run build
+node examples/plugins/assistant/build.mjs
+node packages/plugin-cli/dist/cli.js pack examples/plugins/assistant/.package --out /tmp/assistant.ncpkg
+node examples/plugins/database-minimal/prepare.mjs tcp://10.77.0.20:3306 /tmp/database-owned.ncpkg
+node examples/plugins/database-rfam-readonly/prepare.mjs tcp://mysql-rfam-public.ebi.ac.uk:4497 /tmp/database-rfam-readonly.ncpkg
+node packages/plugin-cli/dist/cli.js pack examples/plugins/host-actions --out /tmp/host-actions.ncpkg
+node examples/plugins/terminal-selection-draft/prepare.mjs /tmp/terminal-selection-draft.ncpkg
+```
+
+Validate each archive with the plugin CLI and compare against the machine record.
+The owned DB address is packaging-only. A different approved fixture endpoint
+requires a new archive and hash. Preparation does not dial either endpoint.
+
+- Verify default Allow for declared supported capabilities without a mandatory
+  first-install permission checklist or repeated permission-only dialogs. Verify
+  per-plugin Ask/Deny, one scoped Ask receipt, readable host-selected labels,
+  lifecycle invalidation and redacted audit. Preserve necessary target selection
+  and inert draft editing, exact resources, source isolation and sandboxing.
+- Verify the assistant's cold startup through the normal host without opening
+  the AI sidebar. Native inference on frozen 677 returned unavailable; the
+  independent startup regression did not establish that native error's cause.
+  Use only the deterministic synthetic provider and Note recipe, with current
+  policy semantics. Native success is not claimed before that recheck.
+- Frozen 677 Host core passed per parent; old consent recordings describe the
+  prior policy. They do not certify the new permission implementation.
+- Terminal's source-level finding is fixture-sensitive-input fail-closed:
+  `fixture-A> ` is untrusted; `fixture@owned-A:~$ ` is confirmed shell. Parent
+  reports corrected-fixture solo/split core passed on unmodified 677. Focus
+  remained unreliable/unverified, and QA sent one Enter in A during a palette
+  attempt. Do not claim global zero input or full terminal native acceptance.
+  Keep the inert draft's no-PTY-dispatch property distinct from that QA action.
+  Exclude diagnostic instrumentation. Prior-policy results do not certify the
+  new policy; the next native priority is final-policy and cold-start AI QA.
+- Native Rfam's single baseline run failed with sanitized -32014 socket error
+  before connect resolved. Auth/SELECT were not reached; transport causality and
+  auth/TLS compatibility remain unverified. No probe/fallback or restriction
+  change is authorized by this coding task. Owned DB fixture prerequisites and
+  parent coordination remain separate.
+- Record exact head, hashes, ordered prompt/operation outcomes, screenshots and
+  video for the new candidate. Hosting/distribution/deployment remain pending;
+  no main merge, Ready transition or release is part of this handoff.

+| Policy `1551fa8355021b5a811d737d16f81e8070f99f5d` | Merge `714e2397a43dc6c083dce8afeeb7a0475de11384` | `PluginLogSettings.tsx` removes the idle-row security marker and opts the nested verbose confirmation into it; `confirm-dialog.tsx` adds the optional host-only marker with default false |
+
+All four production files exactly match their respective owners. Main has only
+those two new commits since common base f0897c3c. Neither changed file overlaps
+the prior plugin changes. The new prompt utility is not imported by plugin
+production modules; plugin sensitive-input, selection and source guards remain
+unchanged. Existing prompt and live-PTY-byte suffix tests still reject bare
+markers and pending input. These are synthetic tests, not a new native SSH pass.
+
+The input also owns its real Settings landing regression and documentation.
+The existing observer, Ask marker, IPC/window authority, sandbox, resource/source
+controls, AI d33 wiring, schemas, sample bytes and package/lock inputs are
+unchanged. `ModelSelector.tsx` equals2433: separate #4002 is not included. Global
+Agent/custom Chat #4006 and terminal diagnostic #3999 are excluded. No main merge,
+Ready transition, original-PR closure or release is part of this handoff.
+
+The parent reports the1551-vs89 independent delta review scoped clean: idle
+Settings no longer requests suspension, the real logging dialog remains marked,
+its nested verbose portal protects itself while the parent is accessibility-
+hidden, closing the nested dialog leaves the parent protected, and closing all
+dialogs permits restoration. This source-only result is not native resolution
+of the recorded Settings blank body.
+
+## Frozen2433 native results
+
+The parent supplied these results; this coding executor did not run the GUI:
+
+| Case | Result on2433 |
+| --- | --- |
+| Main Ask visible | Passed |
+| Cancel | Passed; zero provider POSTs |
+| Accept | Passed; one provider POST |
+| Stream chunks | Passed; no repeated permission prompts |
+| Content Deny | Passed |
+| Real five-minute chat expiry | Passed |
+| Settings sample body | Blank; not accepted |
+
+The idle-row suppression defect is source-confirmed. The correction requires a
+new native Settings recheck; no native success is inferred from the DOM regression.
+A later GPU exit9 and incomplete cleanup were reported separately. Its cause is
+unclassified; no source hotpatch or sandbox/GPU workaround was used here.
+
+Consumer verification of2433's Library renderer is complete: the parent checked
+the matching full source/backend and all1001 renderer hashes, with native inputs
+unchanged. The earlier producer download failure remains historical evidence,
+not an outstanding consumer transfer blocker. That verified artifact still
+certifies2433 only; it does not include1551 or the new main renderer behavior.
+
+Earlier020 Default Allow cold Send/completion, Stop/Deny/restore and themes,
+677 Host core, and corrected-fixture terminal solo/split results remain scoped
+historical evidence. Terminal Focus is unreliable/unverified and QA sent one
+Enter inA during a palette attempt: no global zero-input/full-terminal-pass claim.
+The historical Rfam attempt failed socket transport before connect resolved;
+authentication/SELECT were not reached and cause/auth/TLS compatibility remain
+unverified. Final source-policy, DB, placement/lifecycle and actual hosting/CDN
+gates remain separately reconciled by the parent.
+
+## Local checks and sample provenance
+
+| Check | Result |
+| --- | --- |
+| Registered plugin runtime | 695 passed, one native skip; zero failed/cancelled |
+| Contract/SDK/CLI | 91 passed |
+| Offline examples | Five passed, one Docker opt-in skip |
+| Changed main owner/scope/prompt/suffix and terminal lifecycle group | 139 passed |
+| Actual mounted AI/permission/selected-context/Host group | 21 passed |
+| Settings boundary and security visibility group | 38 passed |
+| Contract/capability/Codex generation and committed drift | Clean |
+| Lint | Zero errors, seven existing warnings |
+| Five sample archives | Validated, built twice and byte-identical to2433 |
+
+The final exact-head normal production build, renderer inventory, bounded
+credential check, CI and Codex review are recorded in the Draft PR/artifact
+handoff. Local full-suite, native packaging and GUI success are not claimed.
+Locked dependencies, standard patches and the official pinned Electron binary
+were prepared normally; no header, HOME, sandbox or native shim workaround.
+
+[Exact sample IDs, permissions/resources and hashes](settings-main-packages.json)
+preserve all prior provenance, including Assistant7943d4c3, ownedDBf01c6a24,
+Rfamaaca5866, Hostcf04f82d and terminal4c9c2388. Whole archive equality was
+asserted, rather than inferred from unchanged source. The owned10.77.0.20 endpoint
+is packaging-only, not a running fixture. No package was activated or service
+queried by this executor.
+
+The owner's separate QA-only Settings Ask sample has reported SHA-256
+`9502a58a4804862e4b13de9fc0d1baf6ad8c2bc681c08b5c0664b552ef0aafc4`.
+It is not one of these five repository examples and was not rebuilt here. The
+native owner must retain its exact verified manifest/source/permissions and
+fixture provenance; no package ID, permission expansion or hash equivalence is
+invented by this integration.
+
+## Native preparation and bounded recheck
+
+1. After the parent's GUI/Nginx slot is released, use a NEW isolated checkout of
+   the final exact head and a separate synthetic QA profile. Preserve the old2433
+   workspace/profile and recordings. Materialize the new private Library artifact
+   in the consumer's own workspace and verify archive and every renderer hash.
+2. Use the complete matching backend checkout: frontend-only dist does not carry
+   the CJS prompt helper or native dependencies. Match package/lock hashes to
+   independently normally rebuilt native inputs and prepare workspace packages
+   normally. Install dist as a whole; use the ordinary Electron launch without
+   Vite and with normal sandbox/helper settings. This is unpackaged native
+   production-renderer QA, not packaged-binary certification.
+3. Open the verified Settings sample through its existing supported settings
+   entry. Check the idle body is visible/clickable with the logging row present.
+   Open logging and the nested verbose confirmation separately; native content
+   must yield to each, remain hidden after cancelling the nested confirmation,
+   and restore only after the parent closes. Do not enable real verbose logging
+   or collect real content for this check.
+4. In the ready/focused/visible/unlocked Settings owner, exercise its synthetic
+   own-setting Ask operation. Record visible Ask, explicit cancel/accept, exact
+   current operation outcome and restoration. Recheck main Ask briefly. Preserve
+   the2433 main/content/expiry counters and any unrun matrix cases separately.
+5. Use owned synthetic A/B AI chats: form a workspace, prefer B, dissolve while A
+   survives and confirm both histories stay with their owners. Remove A and
+   check bounded fallback to B. Confirm handoff alone does not invoke a model or
+   re-share content. Exercise selected-target invalidation across the transition
+   with inert drafts and no PTY input. Do not treat earlier Focus uncertainty as
+   resolved by this main domain fix.
+6. Record exact source/artifact/sample identities, screenshots/video, request
+   counters, cleanup and unrun cases. No fallback endpoint/probe, real credentials,
+   paid API, security relaxation or unrecognized installation is authorized here.
+
+If main advances after this pinned a0cf snapshot, compare the new delta and assess
+its affected checks before landing. The current candidate deliberately does not
+chase unrelated changes while native preparation is in progress.

陈大猫 Cursor Agent 陈大猫	2796d1113a	fix(mcp): reconnect external calls that race a closed socket (#4016 ) A peer FIN can leave readyState closed while destroyed is still false. Concurrent tool calls wrote into that socket, hit writeAfterFIN, and failed with "TCP connection lost" instead of sharing one reconnect. Treat that socket as down, and make later callers join the in-flight re-auth.

bincxzandCursor	336ab5ab17	fix(appearance): repaint native background on explicit theme pushes Keeping the restore guard for registration-time chrome setup is right, but it also swallowed explicit setTheme/setBackgroundColor pushes: windows that had never enabled blur stopped repainting their native backing, leaving the color stale after theme changes on every platform. Separate the two call kinds with an explicit forceBackgroundColor flag so registration still preserves the window's creation-time color while theme and background-color pushes always land.

bincxzandCursor	ce9fcdfec6	fix(appearance): sync macOS blur across windows and gate search by platform Addresses review feedback on the frosted glass background setting. - Detached #/session-window renderers run with settings sync disabled, so `applySharedWindowSetting` now forwards the blur key. Previously the main process put native vibrancy on those windows while their renderer class stayed stale, leaving them opaque with blur on and double-applying opacity with blur off. - Only settings-owning windows persist the blur preference and drive `setWindowBackgroundBlur`, matching the other OS-effect guards. Detached windows still apply the transparent backing class locally. - Search entries can declare `platforms`; the macOS-only blur setting is filtered out on Windows/Linux so a hit never jumps to a tab whose anchor is not rendered (including the default empty-query list). - Restoring chrome only rewrites the background of windows this module made transparent, falling back to the active theme color when no theme color has been pushed yet.
