+# 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.
+

+`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`
+records the parallel check. The appearance-only sample change is independently
+published as `e325742abf9fd329f1f7858eda66367e7a62357c`; its package hash is

+# 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.

+Only the main process fetches the selected source's same-origin asset. Existing
+URL, credential, redirect, timeout, byte-count, and SHA-256 checks apply. The host
+rechecks the source and selection after asynchronous work. The existing isolated
+icon rasterizer validates and converts PNG or WebP to a bounded PNG data URI,
+using its current queue, pending-work map, and cache. No renderer URL, arbitrary
+file path, GitHub API, or GitHub avatar URL is accepted. Visible rows load lazily.
+
+Installed presentation uses already validated catalog metadata only when source,
+version, package digest, and manifest match the active installation. It does not
+fetch a catalog just because the installed list opens. Without an exact match,
+the declared publisher and placeholder remain visible, without a maintenance
+badge. No installed-data migration or persistent identity cache is added.
+
+## 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.

+| Rejected-install catalog refresh | `50fda91424c915c1497e53a87a210e3943cb1e39` | Separate correction after bounded review; service and mounted-row regression only |
+
+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.

+- Settings uses existing `SettingRow` and Select components. It shows each
+  declaration's resource scope and effective Allow / Ask / Deny mode.
+- Policies use `plugin_host_preferences`, keyed by host source owner and
+  capability. They survive restart and updates within the same source, including
+  reintroduced capabilities. New capabilities default to Allow. Existing grants
+  still use the original package/declaration principal; they were not widened.
+- Explicit source reset clears that source's policies and private plugin data.
+  Another source receives independent defaults. Unrelated Vault, host, settings
+  and user data are preserved. No plugin-policy migration was added.
+- Policy edits clear grants, cancel pending/in-flight work and invalidate
+  handles. Settings edits require the exact host-issued source/version/policy
+  revision, so stale controls cannot change a replacement source or override a
+  newer Deny.
+- Ask decisions use the existing in-app Dialog/Button components, reached only
+  through trusted managed-app-window preload IPC. A one-use response token binds the
+  request; close, cancel, lock, blur/hide, reload, renderer crash and shutdown
+  invalidate it. Plugin DOM clicks confer no host gesture authority.
+- Host selection, model/context selection and draft editing remain workflows.
+  Ask is integrated into their existing host UI where applicable. Allow removes
+  permission-only sharing and connection confirmations while retaining exact
+  target validation and action tokens. Terminal drafts never send PTY input.
+- AI start combines model permission and exact selected-content scopes into one
+  Ask decision. Its receipt cannot cross an RPC operation. Broker-bound stream
+  reads/stop/close do not ask per chunk. Same-origin network redirects reuse the
+  current operation decision; different origins still require declared bounds
+  and their own authorization.
+- Policy edits, decisions, use/revoke and operation outcomes remain auditable.
+  Audit records omit note/terminal bodies, model payloads, credentials and tokens.
+  Optional local log persistence remains user-controlled.
+
+See [the security boundary](security-and-permissions.md) for the storage and
+update rules. The separate AI cold-start provider-sync fix is not included;
+`configuredModel.ts`, `trustedHostRuntime.ts` and `usePluginAIContextHost.ts`
+were left untouched for parent integration.
+
+## Review corrections after the initial 643e71b checkpoint
+
+The initial commit and its screenshots remain in history. Registered regressions
+reproduce three concrete issues on that exact tree and pass with these repairs:
+
+- Selected-summary Ask now delegates its decision to the existing host chooser.
+  The first and only interaction is target selection; Allow uses that same
+  necessary chooser, while Deny opens none and releases no summaries.
+- The registry creates a fresh host-only operation identity for every RPC.
+  Internal model contexts retain it when replacing a cancellation signal, so a
+  combined model/content Ask receipt survives that derivation. Receipts also
+  bind plugin, runtime, source, principal and policy revision, and cannot cross
+  operations. Current declaration, policy and selection checks still run.
+- Changing the privileged development-only `runtime.advanced` policy to Ask or
+  Deny disables/stops the activation through the existing manager mutation queue
+  before the policy IPC completes. A source-owner check inside that queue prevents
+  an old source's teardown from disabling a replacement. Browser sandbox policy
+  and development admission guards remain unchanged.
+
+Ask now presents the current host-selected model label and Note title/scope.
+Exact versions remain bound internally. Labels come from the checked broker chat
+and owned selected summaries;
+plugins cannot supply operation identities or display fields through RPC params.
+Opaque selected handles remain internal, and display metadata is not added to
+audit records. The chooser copy reflects Allow / Ask / Deny without claiming a
+mandatory second text review. Spanish keys preserve the existing locale parity
+contract. The quota and expiry regression now uses independent requests to avoid
+its former 20ms timer race.
+
+Updated component previews use a realistic opaque selected handle internally:
+
+| Light Ask | Dark Ask |
+| --- | --- |
+| ![Model and Note labels in light Ask](evidence/permission-modes/plugin-permission-model-ask-light.png) | ![Model and Note labels in dark Ask](evidence/permission-modes/plugin-permission-model-ask-dark.png) |
+
+These remain synthetic Chromium component previews, not native QA or a recording.
+No Library item was created. The original four screenshots below are retained as
+initial-checkpoint evidence.
+
+## Latest checks and remaining environment blockers
+
+- The native candidate `2433cf0130d1c3274c56c39e5765349c2945de01` retains the
+  same idle logging-row marker as `89beeb9` (source blob
+  `4dd5a7cea4ae5a6addc5db5c162038d8fa44075c`). Actual Settings landing plus the
+  existing observer reproduces native-child suppression with no dialog open.
+  This source defect is separate from the worker's earlier GPU exit and does
+  not alone establish the cause of the recorded blank native body.
+- The scoped correction removes only the idle-row marker. Actual logging and
+  Ask dialogs remain marked. A real nested verbose confirmation test also
+  reproduced premature restoration when its parent became accessibility-hidden;
+  that confirmation now opts into the existing marker on its own dialog content.
+  The observer, window trust, permissions and data access are unchanged. The real
+  landing regression verifies idle visible, each security dialog hidden, and
+  restored on dismissal. Focused group **six passed**; Settings boundary group
+  **36 passed**. Both pre-fix failures are retained outside the source tree.
+  Production build and full lint pass (zero lint errors/seven existing warnings).
+  Full TypeScript remains baseline-equivalent at 774 diagnostics with zero
+  added/removed. Exact-head CI and the next frozen native recheck are separate
+  gates; neither is inferred from these local tests.
+- QA-only **Settings Ask QA 0.1.0** uses its supported `location: settings` entry
+  and public SDK to read only its synthetic own setting after an explicit click.
+  Exact archive SHA-256:
+  `9502a58a4804862e4b13de9fc0d1baf6ad8c2bc681c08b5c0664b552ef0aafc4`.
+  Its HTML/CSS/JS each return 200 with proper MIME/CSP through the actual plugin
+  protocol. It contains no raw IPC/test hook or external access. No GUI or running
+  app was changed by this correction; parent will build a new frozen candidate
+  after current cleanup and repeat native Settings acceptance.
+- A registered regression reproduces `Plugin permission decision provider failed`
+  on exact `79a9bd6` when a Settings-owned view activates a real `settings.get`
+  API configured Ask while main is unfocused. The follow-up uses the existing
+  managed-window registry (including Settings), per-renderer readiness and the
+  same in-app component. It does not focus main or expand plugin-frame trust.
+  The actual Settings factory, installed package/SDK activation, view command
+  IPC and permission IPC now pass main/Settings/foreign/background, subframe,
+  independent readiness and hide/close/stale-token checks. Native Electron
+  objects are represented in this regression; this is not native GUI acceptance.
+  Focused boundary group: **67 passed**; renderer/native-view visibility group:
+  **three passed**; runtime aggregate: **695 passed/one native skip**. The initial
+  renderer assertion incorrectly expected a view to reappear while the separate
+  permission-settings security surface remained visible; the corrected test
+  checks both overlapping surfaces and restoration after both close.
+  Production build passed (69 seconds). Full lint passes with the same seven
+  warnings after moving a leftover screenshot harness out of the source tree;
+  its initial lint failure is retained. TypeScript remains baseline-equivalent
+  at 774 diagnostics, with zero added/removed after path normalization.
+- Subsequent exact `da4e809` workflows **40444934631** (tests) and
+  **40444934738** (packages) passed. The full suite reports **15,392 tests:
+  15,342 passed, 50 skipped, zero failures/cancellations**. The runtime group
+  reports 694 passed/one native skip, and package settings 35 passed. All four
+  platform package jobs passed; release jobs were skipped. This does not replace
+  manual plugin native acceptance or erase the local failures below.
+- A focused wording follow-up removes the implication of mandatory prompts from
+  the package detail's sensitive/unbounded scope text in English, Spanish,
+  Russian and both Chinese locales. The Russian declaration note now also
+  reflects default Allow instead of pre-activation permission ceremonies.
+  The complete local CI boundary command passes after this copy change:
+  contract generation is current, runtime 694 passed/one skip, examples five
+  passed/one skip, and package settings 35 passed. Locale parity six passed;
+  changed-file lint has no errors/warnings.
+- Exact `2eee561` packaging workflow **40443396402 passed** on Linux x64,
+  Linux arm64, macOS and Windows; release jobs were skipped. Its first Linux
+  test job **121988800130** stopped on a runner shutdown signal, with no observed
+  assertion failure. Parent requested one retry. Fresh job **121992430185**
+  passed the 694-test runtime aggregate (one native skip) and failed two
+  package-detail assertions still expecting the superseded "not a grant" copy.
+  The full suite was skipped. Those assertions now verify default Allow,
+  adjustable Ask/Deny and retained host/resource validation; development-runtime
+  disclosure and HTML escaping remain checked. No production behavior changes
+  accompany this test correction. Original interruption/failure logs are kept.
+- Registered runtime recheck: **695 tests, 694 passed, zero failed/cancelled, one
+  native skip**. Separate final registered receipt/authority group: **21 passed**.
+- Serial mounted renderer/Host/selected-summary/panel/locale group: **35 passed**.
+  A preceding concurrent run timed out during build/lint load; its failure log is
+  retained. No timeout result is reclassified as a pass.
+- Advanced-runtime manager/source lifecycle and AI group: **35 passed**.
+  Receipt/declaration group: **32 passed**. Final engine/registry/manager/host
+  boundary group: **71 passed**. Final registered AI audit/receipt check: **one
+  passed**; an earlier 15-second timeout while the preview was active is retained.
+  The serial rerun passed in five seconds. Contract/SDK/CLI: **91 passed**.
+- Final production build passed in **45 seconds**. Full lint has zero errors/seven
+  existing warnings. Full TypeScript remains **774 diagnostics**, identical to
+  frozen 677 after path normalization, with zero added/removed diagnostics.
+- The normal official Electron installer succeeded using its documented proxy
+  support and a task-local cache. Exact **42.11.12** executes in Node mode; no
+  shared libraries are missing. This is not native GUI acceptance.
+- Exact-header setup via the installed node-gyp 12.4.0 and the unchanged rebuild
+  tool's official URL failed. The proxy returns **403 Forbidden** for
+  `https://www.electronjs.org/headers/v42.11.12/node-v42.11.12-headers.tar.gz`.
+  That download stopped; no mirror, alternate host, checksum bypass, dependency
+  shim, native-rebuild skip, HOME change or sandbox change was used. Normal
+  postinstall/native rebuild and desktop packaging remain incomplete.
+- A private task-local `TMPDIR` uses Netcatty's existing safe-temp resolution to
+  its normal `Netcatty` subdirectory; HOME remains unchanged. This fixes the
+  earlier fallback-to-unwritable-home prerequisite without changing app code.
+- A **diagnostic full-suite run on the evolving worktree**, after those environment
+  repairs, reported **15,059 tests: 14,922 passed, 92 failed, two cancelled, 43
+  skipped**. A stuck FIDO child was terminated after its timeout; this is not a
+  successful completed exact-head aggregate. Frozen-baseline focused runs
+  reproduce its FIDO timeout and **28 failures** across native imports, Cursor
+  fixtures and repository postinstall patch checks, plus the earlier six
+  Markdown comparison assertions. Other failures remain unclassified. The
+  permission locale parity and obsolete forced-review expectations found by that
+  run were corrected and pass focused checks. Original failed/incomplete runs
+  below are preserved.
+
+The independent AI cold-start production files remain untouched. This branch
+updates only policy expectations in `components/PluginAIContextHost.test.tsx`;
+parent integration must retain the AI owner's actual-main-allowlist and provider
+sync assertions when merging that test file.
+
+## Local evidence
+
+These are local code/test results, not native acceptance:
+
+| Check | Result |
+| --- | --- |
+| Registered runtime aggregate, concurrency 2 | 693 tests: 691 passed, one failed, one native skip; no cancellations. Sole failure imports the missing Electron binary on real worker reconnect. |
+| Engine, policy matrix, trusted prompt and policy IPC group | 79 passed; subsequent shutdown guard test: 9 passed. |
+| Mounted in-app permission controls and Host/terminal workflows | 22 passed. Includes Host Allow/Ask/Deny, policy change during save preparation, exact targets and stale replies. |
+| Registered AI/context + policy group | 7 passed, including normal Allow, combined Ask, Deny and revocation. |
+| Source/version/revision edit guards and registered byte-stream group | 47 passed. |
+| Contract/SDK/CLI suite | 91 passed. Four prepared sample archives validate. |
+| Lint | Zero errors, seven existing warnings. |
+| Production build | Passed; final `pack:dir` build also passed in 76 seconds. |
+| Contract/capability/Codex generation | Regenerated/checks clean; no capability-tool diff. |
+| Full TypeScript check | Frozen baseline and implementation each have 774 diagnostics; zero added/removed after normalizing worktree paths. |
+| Full `npm test` | Incomplete: stopped after three unchanged bridge child processes remained pending. Reported 9,891 tests, 9,359 passed, 40 failed, 478 cancelled, 14 skipped. This is not a passing aggregate. |
+| Desktop `pack:dir` | Unpassed: native rebuild attempts `/home/agent/.electron-gyp`, outside this workspace's writable roots. Earlier pinned Electron installation failed with `fetch failed`. No shim, alternate runtime or sandbox change was used. |
+
+Frozen-baseline focused runs reproduce the two large-history SFTP recovery
+failures, six Markdown comparison failures, and missing-Electron adapter/serial
+failures observed in the broad run. Other broad-run failures remain unclassified;
+unchanged code alone does not prove a baseline failure. One earlier runtime
+aggregate hit the existing 15-second byte-stream fixture timeout during concurrent
+builds; its focused run and the final aggregate above pass that case.
+
+Logs and archives are in `/workspace/permission-evidence/` in this execution
+environment. The final task report identifies any remaining blockers and checks.
+Exact-head CI and native acceptance remain pending parent coordination.
+
+## Component screenshots
+
+Chromium rendered the actual React components with built-in light/dark tokens
+and synthetic host bridge data. These images demonstrate layout and state only;
+they do not certify Electron behavior.

+
+## Parent-serialized native recheck
+
+1. Use a fresh isolated app profile and the exact next integrated head. Import and
+   enable a sample: no installation permission ceremony should appear.
+2. In Allow, select hosts in the host chooser, create/edit via the normal draft
+   editor, and connect using a current selected reference without a separate
+   plugin confirmation. Ordinary SSH authentication and host-key checks remain.
+3. Select a Note/context and model, start and read a turn in Allow. Then switch
+   AI/content to Ask: one scoped decision covers the turn and exact references,
+   with no per-chunk or second content-sharing dialog.
+4. Check terminal Allow sharing and the editable inert draft; Ask shows one share
+   preview; Deny releases no selection and cannot reopen old handles.
+5. Check network Allow/Ask/Deny at the declared endpoint. Preserve all endpoint,
+   DNS, redirect, private-network and control-plane rejection checks.
+6. Flip policy while a chooser, draft, model read or network operation awaits.
+   Old results/tokens must fail. Switch back to Allow and start a fresh operation.
+7. Restart/update the same source with an explicit Deny; it must remain Deny.
+   Check distinct plugins and sources, stale settings edits and explicit source
+   reset. Review bounded audit events and optional local logging for redaction.
+8. Open a plugin view from standalone Settings and exercise an Ask-gated API
+   during activation and from its own view command. Ask must be reachable in
+   Settings without focusing main or losing the view. Close/hide/reload that
+   window, switch to an unrelated window, and try a stale response: old authority
+   must be cancelled, with no background-window fallback or plugin-frame reply.
+
+No merge, release or native acceptance is authorized by this handoff.

+# Permission-policy and AI acceptance candidate
+
+This records frozen 020 and its predecessor evidence. For the later managed-
+window Ask correction, use [the isolated Ask integration record](ask-routing-integration.md).
+020 native Default Allow/Stop/Deny/restore/themes passed; Ask had no visible
+dialog and timed out with zero new model requests. Ask acceptance/cancel and
+the content-read matrix remain unrun until that new candidate is checked.
+
+Use the dedicated `integration/plugin-policy-ai-acceptance` branch. Its Draft PR
+records the exact published head and aggregate CI. Frozen #3997 at
+`677aac33b1eec9dbd4a367417a49c964cdea63e7` remains the historical native baseline;
+neither that branch nor main is changed by this integration.
+
+This is a candidate for parent-coordinated acceptance. It is not a claim of
+completed native acceptance, deployment readiness or permission activation.
+
+## Preserved inputs
+
+| Input | Exact checkpoint | Integration |
+| --- | --- | --- |
+| Frozen integration | `677aac33b1eec9dbd4a367417a49c964cdea63e7` | Starting point; includes stream/source/Host/settings and prior terminal history |
+| Permission policy #4000 | `79a9bd6df1c17fd8a5238aba31d7a8b4cda184b9` | Initial ordinary merge `9aa899059` preserved 2eee561; follow-up ordinary merge `cfa13680e` preserves the authoritative scope/sensitivity copy and tests |
+| AI #3986 | `d33c0193ccaedc1a10aed9da495f040250121bef` | Ordinary merge `5d2ff1cb8`; cold-start wiring, themed sample and Node 22 warning-drain test correction |
+| Terminal production | #3996 `8e7c28fe1bdbcdd76816d33ec926ba8e60eefe64` | Preserve the prior renderer eligibility/publication path; policy-owned interaction changes remain from #4000 |
+
+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

+node examples/plugins/assistant/build.mjs
+node packages/plugin-cli/dist/cli.js pack examples/plugins/assistant/.package --out /tmp/assistant.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

+- Verify default Allow for declared supported capabilities without a mandatory

+  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.

 # Plugin security and permission boundary
 
-Status: phase 3 internal preview (`0.1.0-internal`)
+Status: unreleased plugin platform; browser plugins remain sandboxed. Advanced
+utility packages remain restricted to developer mode.
 
-This phase is available only with `NETCATTY_PLUGIN_DEV=1`. It is deliberately
-usable by later contribution and Provider phases, but it is not a public plugin
-release. There is no renderer permission UI yet. The first-party development
-bootstrap injects a native Electron confirmation dialog; embedders that do not
-inject a decision provider still fail closed.
+Declared capabilities that the platform exposes default to **Allow**. Installing
+or enabling a plugin does not open a permission checklist. In Settings, each
+plugin has host-owned **Allow / Ask / Deny** controls with its declared resource
+scope. Allow skips permission dialogs; Ask requests one scoped decision; Deny
+rejects before side effects or content release. Target selection, model selection,
+and editing/saving drafts remain normal host workflows. SSH authentication and
+host-key checks are unchanged.
+
+## Policy storage, updates and source changes
+
+Policies live in `plugin_host_preferences`, separate from plugin-writable
+settings, under `permission:<host source owner>:<capability>`. Missing entries mean
+Allow. No historical plugin-policy migration or unrelated user-data reset runs.
+Policies survive restart, disable/re-enable, uninstall/reinstall from the same
+source, and package/version/publisher/declaration changes within that source.
+An explicit Deny therefore survives an update, including removal and later
+reintroduction of that capability. New declared capabilities default to Allow;
+existing Ask/Deny modes apply to the current declared scope. Undeclared
+permissions, unsupported methods and out-of-scope resources still fail closed.
+
+Changing a source requires the existing explicit uninstall/private-data reset.
+That reset removes only the old source's plugin policies and private records.
+A different source receives independent defaults. Policies never come from a
+manifest, plugin setting, RPC payload or imported grant. Existing grant hashes
+still include the immutable package principal and declaration boundaries; this
+change does not turn an old package grant into a cross-version grant.
+
+Every policy edit clears saved grants, cancels pending decisions and active RPCs,
+and invalidates host resource handles and model/stream state. Guards bind the
+source and policy revision before asynchronous authorization resolution, recheck
+before commits and content delivery, and remain invalid after a Deny-to-Allow
+flip. A late prompt reply cannot revive old work. The user must start a fresh
+operation after changing policy.
+
+Ask uses Netcatty's existing in-app Dialog, typography and theme. Its recipient
+must be a ready, focused, visible, unlocked top-level app renderer in the managed
+window registry, including the standalone Settings window. Arbitrary windows,
+plugin view contents and subframes cannot register or respond. Each single-use
+token and cancellation lifecycle remains bound to the receiving window; another
+renderer's readiness changes cannot cancel or inherit that request. No main-window
+focus handoff is needed. Close, cancel, timeout, lock, hide/blur, reload, crash
+and stale runtime/source fail closed. The dialog uses the existing host security
+surface marker so attached native plugin views yield while it is visible and
+restore through their existing lifecycle on dismissal.
+Ordinary landing rows do not suspend native views. The logging dialog and its
+verbose confirmation are marked security surfaces; the confirmation opts into
+the existing marker because it temporarily accessibility-hides its parent dialog.
+A plugin DOM click never becomes a host gesture. Choosers, drafts, terminal and
+clipboard sharing use their existing host-owned action tokens. Ask integrates
+with that workflow instead of opening a second capability dialog. Allow skips
+sharing and connection permission confirmations while retaining validation and
+operation/resource binding. AI start combines model access and exact selected
+context handles into one Ask decision; its receipt is limited to that operation.
+Stream reads, stop and close validate broker handles without prompting per chunk. The receipt uses a host-created RPC operation identity retained by derived
+model contexts, with source/runtime/principal/revision binding. It is never a
+plugin-provided field. The selected-summary chooser owns its Ask interaction;
+there is no preceding generic capability prompt. Ask displays checked host
+model/selection labels rather than opaque selected handles.
+Selected-context reads remain selected-only and never enumerate the whole Vault.

+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.
