 # Unified plugin acceptance candidate

+This file records the frozen 677 native baseline. For the subsequent permission

 The dedicated branch is `integration/plugin-native-acceptance`. Its Draft PR
 records the exact current head and CI runs. Native AI, database, Host/Vault, and

+# 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`
+records the parallel check. The appearance-only sample change is independently
+published as `e325742abf9fd329f1f7858eda66367e7a62357c`; its package hash is
+`7943d4c3800914fe0acd3d0f3a3d7f7c1910c212a5dc58a044871a6a82485274`.

+# 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.

+# Plugin author presentation
+
+The marketplace displays the catalog's author next to a small avatar. Installed
+views reuse the author row. Missing, loading, unavailable, or invalid imagery
+uses a bundled placeholder. An avatar is presentation metadata, not proof of an
+authenticated GitHub publisher.
+
+The registry binds an image to its reviewed displayed-author subject. Repository
+ownership alone does not establish that subject. The current first-party author
+is the Netcatty project, not an assumed personal GitHub identity. Until an image
+pin is reviewed, its avatar remains null.
+
+## Avatar delivery
+
+Delivery v2 extends the reserved `avatar` field to null or
+`{path, sha256, size}`. The path is exactly `/assets/<sha256>.png` or `.webp`.
+Size is a positive integer no greater than 256KiB. The delivery digest and existing
+id/version/repository/commit tuple bind the reference. Catalog and index identity
+fields do not change. Source-only delivery v1 remains supported.
+
+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.

+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.

+
+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.

+# Global Agent continuation: bounded QA recipe
+
+This is a separate increment after the plugin platform foundation. The transport
+review checkpoint is #4012 at `ea619555`; its isolated correction is `63f0572e0`.
+The runtime continuation carries the correction through an ordinary feature-branch
+merge. It is not merged to main or accepted for release.
+
+## Reproduce the installable sample
+
+From the exact runtime head reported in the handoff:
+
+```sh
+npm ci
+npm run build:plugin-runtime-deps
+node examples/plugins/global-agent/build.mjs
+node packages/plugin-cli/dist/cli.js pack examples/plugins/global-agent/.package --out /tmp/netcatty-global-agent.ncpkg
+sha256sum /tmp/netcatty-global-agent.ncpkg
+```
+
+The reproducible sample SHA-256 is
+`f0edf43523845847d5dbb74b0c4d8cd3bfe8e0f89ca193f28140e6b47dc45ed0`.
+Two independent package builds matched. Build scripts and tests are excluded
+from the six-file installed package.
+
+The sample reserves transcript space inside the actual 798-by-548-pixel plugin
+viewport measured during native QA. In a scheduled native test environment, run
+`npm run test:plugin-global-agent-layout` for the bounded render regression. It
+loads the real sample HTML/CSS with synthetic history, including the fixture
+notice, and checks transcript scrolling, reachable configuration, and visible
+mouse Stop. It does not load the plugin script or start an Agent/provider. This
+render check remains pending where the normal browser sandbox cannot start;
+do not disable the sandbox to run it. Also verify the installed sample visually
+at the 1188-by-848-pixel app window before accepting the viewport correction.
+
+For the modal-history lifecycle regression, stop the synthetic stream, close
+the modal with the host X, and reopen it without disabling/restarting the
+plugin or waiting for five-minute lease expiry. Select the owned conversation,
+confirm fresh empty targets, and Open. History must load without another model
+request. Repeat with a new conversation. The sample command runtime retains
+only its last host-issued chat handle and releases that exact lease on explicit
+Open; it does not change core expiry, source ownership or duplicate-open guards.
+
+## Native fixture acceptance (parent-scheduled GUI only)
+
+1. Use an isolated synthetic profile, no real Notes, hosts, histories or keys.
+   Start `node scripts/plugin-global-agent-provider-fixture.mjs --port 9218`.
+   It performs no inference or outbound request and logs no bodies/headers.
+2. Through normal host settings, configure an OpenAI-compatible Chat Completions
+   provider at `http://127.0.0.1:9218/v1`, model `global-agent-fixture`, with the
+   fixture-only literal `FIXTURE_ONLY_API_MARKER`. Do not use real credentials,
+   paid services, allowlist edits, debugger injection or the builtin AI sidebar.
+3. Install the `.ncpkg` in Settings → Plugins and open its contributed Global
+   Agent Chat view. Verify light/dark/accent updates using existing theme tokens.
+4. Choose Catty. Choose no targets, or only owned synthetic terminal fixtures,
+   then Open conversation. The fixture's default tool is `get_environment`; it
+   never requests a terminal command. Record Send → streamed result/usage and
+   `GET /fixture/status` counters. This proves a deterministic pipeline, not
+   real model inference.
+5. Send `fixture:wait`, wait for output, press Stop. Verify aborted count rises
+   once and no late text appears. Capture screenshot/video with fixture labels.
+6. Exercise Actions Ask using the existing in-app policy dialog: approve and
+   deny the scoped environment tool separately. Actions Deny permits model-only
+   chat with no tools. Agent-use Deny prevents dispatch. A policy change revokes
+   existing handles; reselect/reopen explicitly before another Send.
+7. Close/reopen and disable/re-enable only this synthetic plugin. Reselect its
+   targets and reopen its owned conversation. History should survive, while the
+   private per-open actor ID is fresh. At five-minute expiry, the sample asks for
+   explicit reselection and keeps the draft, without resending or renewing scope.
+8. Revoke/disable or lock while streaming and verify cleanup/no late events.
+   Disconnect/re-own a selected synthetic worker during selection and a turn;
+   stale selections must fail instead of binding a replacement connection.
+
+Do not activate a configured real Claude backend in this fixture recipe. Claude
+MCP's code/handler boundary is covered with synthetic tests; authenticated service
+and genuine CLI acceptance remain unverified and require separately approved
+access. Other backends are explicitly unsupported/unavailable. No background
+service, blanket OS/Vault access, merge or release is implied.
+
+## Evidence and limits
+
+- Installed Catty path uses actual `AgentRuntime`, driver, main provider admission,
+  source policy and worker dispatcher, with JSDOM/in-process plugin transport and
+  synthetic workers. It proves selected B dispatch, stream, Stop, revocation and
+  history after runtime restart. This is not a native BrowserWindow sandbox test.
+- Main/core tests cover source/session/resource substitution, scope expiry,
+  approval waits, worker lifecycle, cancellation, late completion, stable source
+  budgets, source-isolated history and no key serialization. Filesystem API reads
+  cannot access the core history root. Explicitly granted terminal commands still
+  have that terminal's native OS authority.
+- No GUI ran in this executor. Native screenshots/video and independent runtime
+  review remain parent-owned gates. The exact-head CI result must be reported
+  separately from focused local evidence.

+# Global Agent plugin bridge (work in progress)
+
+This stack starts from `integration/plugin-ask-routing-acceptance` at
+`2433cf0130d1c3274c56c39e5765349c2945de01`. The parent confirmed this dependency;
+its native Ask acceptance and integrated CI are still pending. This branch does
+not modify the frozen candidate, #3986, #3998, or #4002.
+
+The user approved a global conversation independent of a terminal or workspace,
+with a plugin-provided chat UI and selectable existing Agent backends. Core owns
+Agent execution, history, target authority, native approvals, credentials and
+audit. Global is not unrestricted inventory access or a background service.
+
+## Stage 1: dispatch authority
+
+`electron/plugins/agent/delegatedScope.cjs` is a host-only authority. It does not
+register plugin APIs, start an Agent or implement an orchestration loop.
+
+- `issue(context, hostSnapshot)` authenticates with the existing source binding.
+  Host snapshots contain backend identity/revision, target kind/id/owner/revision,
+  synchronous current-owner checks, and a supported capability subset. The public
+  result contains only an opaque handle and expiry. Plugin parameters must never
+  be used as `hostSnapshot`.
+- `begin(handle, context)` returns an internal turn ticket and AbortController.
+- `dispatch(ticket, context, resolvedAction, execute)` runs the common host policy
+  adapter once, checks current target revisions after any approval wait, invokes
+  the real dispatcher, and rejects late results. `resolvedAction` must come from
+  canonical host capability/argument resolution, not an unchecked plugin object.
+- `assertTurn` guards outgoing events. `finish` and `stop` invalidate the exact
+  ticket. Runtime/plugin release, lock/hide invalidation and shutdown abort work.
+- Handles expire in five minutes. There are at most eight per runtime owner and
+  64 overall, with at most 32 explicit resources per scope. Expiry never silently
+  refreshes a selection or revives an old turn.
+
+The focused tests use the actual `PluginAISourceBinding` with synthetic host
+registries, two terminal owners representing different workspaces, controlled
+time, and deferred approval/native completion. They cover source/runtime/target
+substitution, focus changes, revision changes across approval, policy denial,
+Stop, release, lock, late completion and bounds. They do not yet prove actual MCP
+or AgentRuntime dispatch; those remain integration gates.
+
+Initial execution failed before test discovery because the new worktree has no
+dependencies (`ajv/dist/2020` missing). Running with the existing local worktree's
+read-only CommonJS dependency path passes all 12 cases. No provider, CLI Agent,
+paid credentials or GUI was used.
+
+The adjacent run then passed 49 tests and failed one installed-entrypoint test
+because ESM could not resolve `@netcatty/plugin-cli` from the new worktree. Standard
+`npm ci --ignore-scripts` and `build:plugin-runtime-deps` repaired the setup. These
+failures are setup evidence, not failed-before product regressions.
+
+The core conversation repository stores the existing global `AISession` document
+shape in a host-only directory, namespaced by the hash of source/private-owner.
+Native session identity and compaction remain private. Commits serialize a cloned
+snapshot, revalidate provenance before atomic rename, and retain previous history
+when that check fails. Files use mode 0600 and no-follow reads. The repository
+does not register a plugin storage API or change the source database schema.
+
+The canonical schema and SDK now declare the proposed session interface and
+permissions. Runtime methods and the supported-feature advertisement are not yet
+registered. This stage must not be described as an installable working Agent
+bridge. Focused scope/history/wire and permission-copy tests pass 20 cases;
+contract/SDK/CLI tests pass 91. Focused lint and generated drift checks pass.
+
+## Independent stage-1 correction
+
+The independent review of exact `056164157f34ea779ed6cf51199909082345eca4`
+confirmed two helper defects before any runtime acceptance claim: source failure
+during the initial owner check rejected late work without aborting the active
+native signal; Stop could acquire a replacement turn after awaiting identity.
+
+Both reproduce against that exact helper using the real `PluginAISourceBinding`:
+the focused before run is 13 passed / 2 failed. The correction revokes the captured
+scope when its own host-authenticated identity fails, and captures the intended
+turn before Stop's first await. A foreign runtime cannot use a failed lookup to
+revoke another caller's scope. Focused after: 15 passed / 0 failed. The complete
+foundation/permission group passes 23 on Node 24.19.0 and Node 22.23.3; focused lint
+and diff checks pass. Logs: `/tmp/netcatty-global-agent-review-before.log`,
+`/tmp/netcatty-global-agent-review-after.log`,
+`/tmp/netcatty-global-agent-review-node22.log`.
+
+The first CI run at 0561641, test `40459522087`, Linux job `122040565759`, failed
+after an explicit runner shutdown and operation cancellation, with no assertion
+failure in its log and no complete repository test total. Package workflow
+`40459521971` and both Windows jobs passed. The parent authorized one job rerun;
+it was requested once, producing Linux job `122048349748`, still running at this
+checkpoint. Original runner failure remains historical evidence. Neither that
+rerun nor the helper fix establishes runtime, native or independent-review
+acceptance; the correction still needs reviewer recheck.
+
+### Follow-up: cancellation is not source revocation
+
+The independent recheck confirmed the first two repairs and found a remaining
+Stop race: an aborted Stop(A) RPC could enter the generic owner-failure cleanup
+after B had started, revoking B's scope. The same failure was reproduced at both
+owner-validation await paths using the actual source binding. Exact-18377 source
+with the new 18-case scope suite yields 16 passed / 2 failed; evidence is retained
+in `/tmp/netcatty-global-agent-stop-rpc-exact183-before.log`.
+
+The minimal follow-up distinguishes this request's abort/deadline from verified
+owner or resource failure, rethrows the access failure, and leaves the existing
+turn-capture rule intact. Cancellation of Stop(A) cannot revoke B. A separate
+regression confirms that a verified source mismatch still aborts native work
+even when the RPC is concurrently cancelled. Foreign caller protections remain.
+The full foundation/permission group passes 26 tests on Node 22.23.3 and Node
+24.19.0; focused lint and diff checks pass. Logs:
+`/tmp/netcatty-global-agent-stop-rpc-final.log` and
+`/tmp/netcatty-global-agent-stop-rpc-node22.log`. Independent recheck is pending.
+
+The authorized original-head Linux rerun `122048349748` ended cancelled, with an
+operation-cancelled log and no assertion failure. No second rerun was requested.
+At 18377, test workflow `40462595842`, Linux job `122050816182`, also received an
+explicit runner shutdown; `PluginLogSettings.test.tsx` was SIGKILLed immediately
+afterward. That interrupted stage reports 34 passed / 1 failed, not a complete
+repository total or an assertion failure. Both Windows jobs passed. No blind
+rerun of that job was made. Package workflow `40462595846` was still running when
+checked. These records are not substituted for exact-head green CI.
+
+## Planned public contract and adapters
+
+### Independent transport correction
+
+The exact `ea619555` internal-handler reproductions fail all four targeted cases:
+both no-session and empty-selection environment reads serialize global tool hints;
+stale chat-wide cleanup cancels replacement B; and caller-supplied builtin chat
+text can downgrade cancellation of a main-owned delegated request. The outer
+sender gate still accepts only the current trusted main window. These are trusted
+application lifecycle defects, not arbitrary plugin IPC exposure or installed
+runtime exploit evidence.
+
+Cancellation now resolves ownership from the main request map, rejects a
+conflicting caller chat, checks the recorded sender and current turn lease, and
+cancels only that native request. The legacy chat-wide cleanup IPC is unavailable
+for reserved delegated conversations; main-owned exact-turn release remains the
+cleanup authority. All delegated environment return paths omit global tool hints.
+
+An additional Node 22 regression is independently reproduced: inline arrow
+properties at the beginning of `module.exports` prevent namespace detection of
+existing exports such as `init`, breaking the real Catty attachment harness.
+Identifier exports preserve that existing interface. Correction tests pass 94 on
+Node 22.23.3, including the actual Catty attachment consumer; focused lint passes.
+Failed-before logs are `/tmp/netcatty-global-agent-transport-review-four-failed-before.log`
+and `/tmp/netcatty-global-agent-ea619-namespace-before.log`. The transport PR's
+review checkpoint remains `ea619555` until the parent integrates/rechecks this
+separate correction. No native/backend/full-CI acceptance is implied.
+
+### Stage 2A: trusted native dispatch boundary
+
+The independent bounded recheck of foundation `ba4d3fc` passed all 20 reviewer
+cases. This resolves its reported helper findings; it does not establish full CI,
+runtime, backend or native acceptance.
+
+The additive transport slice gives managed subprocesses a separate per-turn MCP
+credential, permanently binds their TCP connection to that turn, filters their
+tool list, and routes actual tool execution through the source-bound host policy
+adapter. Catty's trusted-app IPC enters the same dispatcher. Branded approval
+contexts skip the legacy Agent approval only after that host adapter grants the
+action; process-global permission mode is unchanged. Selected environment reads
+return the scoped session metadata without querying global tunnel inventory.
+
+Managed Claude is restricted to its existing MCP mode with builtin tools disabled,
+strict MCP configuration and no inherited settings sources. The main native entry
+rejects unverified backends and Skills mode for reserved delegated conversations.
+Each model stream and native SDK request carries a main-owned turn tag; releasing
+that lease aborts its HTTP/native work. Old credentials, cancellation requests and
+disposers cannot acquire or cancel the next turn.
+
+The focused boundary suite passes 116 cases, including an actual local TCP/main
+handler with synthetic workers, plus two new actual-HTTP/renderer-transport lease
+tests. These are deterministic transport tests, not real model inference or
+authenticated Claude service/CLI acceptance. Public runtime registration, core
+conversation integration and the custom chat sample are still separate work in
+progress; this transport slice alone is not a usable plugin Agent feature.
+
+At exact `ba4d3fc`, package CI `40464058910` passed; test workflow `40464058908`
+is red. Linux job `122055141575` failed a real assertion in
+`PluginManagementDialog.interaction.test.tsx:71`: the external view handoff had
+not run when asserted. That stage reports 34 passed / 1 failed; earlier runtime
+and contract groups passed 720 and 5. Both Windows jobs passed. No blind rerun was
+requested. This unresolved assertion must not be classified as runner shutdown.
+
+The wider initial local transport run reports 697 passed / 10 failed / 3 skipped.
+All ten failures are Cursor discovery expectations after `npm ci --ignore-scripts`
+left SQLite's native binding absent, making the bundled Cursor SDK import fail.
+The standard rebuild first failed using unwritable default caches; rebuilding
+with task-local npm/node-gyp cache paths succeeded. The failed totals are retained
+in `/tmp/netcatty-global-agent-transport-expanded.log`; the after-setup run is
+recorded separately. No GUI or provider credentials were used.
+
+After the dependency repair, the expanded transport/native-handler/preload/SDK
+suite passes 709 tests, 0 failures, 3 skips. Log:
+`/tmp/netcatty-global-agent-transport-expanded-after-setup.log`. Focused lint passes.
+
+The proposed feature is `ai.agent-sessions`, with `ai.agent.use` for conversation
+operations and `ai.agent.actions` for actual Agent tool actions. Permission mode
+comes from the existing source-bound Allow/Ask/Deny engine. These are additive
+names, separate from the existing tools-disabled `ai.invoke` broker.
+
+The API will provide backend listing, explicit target selection, owned chat
+listing/opening, sending, bounded event reads, history, Stop and close. Backend
+references are opaque host-issued configuration revisions. Conversation references
+identify only histories owned by the calling source/private-owner; runtime handles
+are separate and cannot substitute builtin chat IDs or native SDK resume IDs.
+Messages cannot supply permissionMode, CLI/env/MCP configuration or owner fields.
+
+Core will reuse `AISession`, `AgentRuntime`, both existing turn drivers, event and
+compaction handling, SDK resume identity validation, and `stopAgentTurn`. The first
+eligible backends are Catty and configured Claude Code in MCP mode. Other backend
+entries must return explicit unsupported/unconfigured status until their native
+tool and approval boundaries are verified. Codex SDK's current unrestricted native
+configuration must not be treated as eligible merely because it has a driver.
+
+The terminal worker already exposes a suitable main-owned resource binding:
+`getPluginSessionBinding(sessionId, ownerWebContentsId)` returns worker epoch and
+session generation. Use this for dispatch-time targets; do not use menu IDs,
+focused tab, display labels, or a renderer-provided session ID as authority.
+
+The MCP dispatcher and Catty direct execution route need the same delegated
+session guard. A delegated call must not update process-global permission mode,
+or request both an Agent approval and a plugin approval for the same action.
+Policy changes, disable/restart/source replacement, lock and host disconnection
+must cancel scoped native work and invalidate outgoing event tickets. Existing
+Agent trace and plugin audit/log facilities will receive redacted correlation
+metadata, not credentials, provider diagnostics or full unreviewed tool payloads.
+
+## Remaining acceptance gates
+
+### Separate runtime/sample implementation checkpoint
+
+The runtime continuation wires the nine `context.agent` methods through the
+registered default host, dedicated trusted-app preload/IPC and `PluginAgentHost`
+mounted in `AppView`. It reuses the existing `AgentRuntime`, Catty/external turn
+drivers, core `AISession` documents, compaction, model/provider transport, native
+cancellation, selected worker epoch/generation checks and permission/audit engine.
+No source database, Vault history or builtin conversation ownership change is
+included. Plugin input cannot supply internal session IDs, source/owner, CLI/env,
+MCP configuration or permission mode.
+
+The first eligible profiles are configured Catty and Claude MCP. Other known
+backends report unsupported/unavailable. Claude has builtin tools disabled,
+strict MCP, no inherited settings sources, at most 12 native turns and no native
+session persistence/resume; its existing driver rehydrates from core-owned history.
+This code path has handler/driver/MCP fixture coverage. Authenticated Claude
+service/native CLI acceptance has not run and must not be inferred from mocks.
+
+Actions use one source-bound Allow / Ask / Deny decision path. Actions Deny permits
+model-only conversation with an empty tool profile; Agent-use Deny blocks host
+dispatch. Explicit target choice is independent of focus/workspace. Worker
+lifecycle changes cancel a pending chooser and revoke stale target leases;
+source/runtime/policy/lock invalidation aborts native work and rejects late events.
+Core history is source/private-owner namespaced and read/write protected through
+the plugin filesystem broker. A user-granted terminal command still has that
+terminal's native OS authority; this is not an OS filesystem sandbox.
+
+Bounds include six sends/source/minute, eight scopes/runtime and 64 total, 256
+retained turn handles, 32 tool actions and 32 Catty HTTP calls per turn, 12 Catty
+iterations, a 120-second turn lifetime, 60-second model HTTP/15-second streaming
+idle deadlines, 128 KiB HTTP responses, 256 KiB projected turn output and 4 KiB
+text events. Usage is projected; no hard total native-Claude token budget is
+claimed. Handles expire after five minutes without silent target reselection.
+
+The installable `examples/plugins/global-agent` sample provides backend/owned
+conversation choice, explicit targets, history, Send/Stop and existing host theme
+tokens. Its deterministic local provider fixture performs no model inference,
+paid API calls, real terminal execution or request/body/header logging. The
+installed Node/JSDOM pipeline test uses actual Catty orchestration, configured
+HTTP admission and main dispatch to synthetic workers. It proves one selected-B
+tool cycle, streamed result, Stop and revoked-handle denial; it is not native
+browser sandbox or real model acceptance. A failed-before JSON-snapshot regression
+is retained at `/tmp/netcatty-global-agent-snapshot-failed-before.log`.
+
+Recorded validation: plugin runtime 732 passed/0 failed/1 skipped; affected group
+105 passed/0 failed/3 skipped; examples 6 passed/0 failed/1 skipped; repaired setup
+paths 284 passed. Build, codegen and lint passed before the final review corrections.
+Typecheck is still red: 774 diagnostics on both unchanged foundation and this
+continuation, with equal per-file/error-code counts; it is not a clean typecheck.
+The repaired Node 22 full run reports 15,354 passed/9 failed/46 skipped. Eight are
+missing xterm install patches, subsequently applied; the ninth is the transport
+CJS namespace regression fixed separately. Exact final-head validation is pending.
+
+The earlier pre-setup full run remains pending after its timed-out unpatched FIDO
+test worker kept a socket open. Reading `/proc/319596/cwd` to confirm that worker's
+identity was denied (EACCES); no signal was sent and no alternate route attempted.
+Its log is retained without invented final totals. `pack:dir` first failed using
+the unwritable default npm cache; a standard task-local cache repaired that step,
+then native rebuild failed because installed `@electron/rebuild` hardcodes
+`/home/agent/.electron-gyp` outside writable roots. No home override or sandbox
+bypass was attempted. Native screenshots/video and independent runtime review
+remain parent-owned gates; nothing is merged or released.
+
+Final focused Node 22 validation passes 205 cases, including all nine failure
+paths from the broad run after the documented setup/correction changes. The
+installed pipeline additionally proves disable/re-enable, owned history reopening
+and a fresh model-only turn under Actions Deny. `conversationRef` is durable;
+each open receives a fresh private runtime actor so revoked privacy/native/tool
+state cannot be revived. A typed, host-only close control clears its owned
+runtime caches after that actor settles. Build, lint (seven existing warnings)
+and generated drift checks pass. Typecheck still has the same 774 per-file/code
+diagnostic counts as the unchanged foundation. Logs:
+`/tmp/netcatty-global-agent-lifecycle-final-tests.log`,
+`/tmp/netcatty-global-agent-lifecycle-final-build.log`, and
+`/tmp/netcatty-global-agent-lifecycle-final-typecheck.log`.
+
+The native recipe and reproducible package hash are in
+[`global-agent-qa.md`](global-agent-qa.md). Remaining gates are independent
+transport/runtime review, CI on the final integrated head, parent-scheduled native
+screenshots/video, genuine Claude compatibility acceptance with separately
+approved access, and native packaging on a machine with supported writable
+rebuild caches. The initial full-run pending worker and previous red totals above
+remain recorded. No GUI ownership, merge or release is granted to this executor.

+020 native Default Allow/Stop/Deny/restore/themes passed; Ask had no visible

+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.
+

+this integration task did not duplicate it. Retry Linux job `121992430185`

+failed those same two `not a grant` assertions: settings group 33 passed/two

+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)

+including both P2s and the three UI findings, with 71 focused/synthetic checks.
+
+The policy owner subsequently corrected these tests in predecessor

+[test CI](https://github.com/binaricat/Netcatty/actions/runs/40444934631) passed

+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.

+# Settings visibility and current-main acceptance candidate
+
+This isolated branch, `integration/plugin-settings-main-acceptance`, starts at
+frozen #4004 `2433cf0130d1c3274c56c39e5765349c2945de01`. Its Draft PR and private
+renderer provenance record the final exact head and CI. Frozen2433 source,
+artifact, QA workspace/profile and earlier evidence remain intact.
+
+## Inputs and production ownership
+
+Both inputs were ordinarily merged, without conflicts or manual production edits:
+
+| Input | Import | Production files and behavior |
+| --- | --- | --- |
+| Current main `a0cf2b487c9ff0b0472d622e66bc5ee20de32c71` | Merge `c4aedfa9ed8c9f2647ac26f0e6e144edab341c2d` | `domain/workspaceAiScopeHandoff.ts` keeps inherited AI chat on a surviving owner when a workspace dissolves (#4003/e3e2dcfe); `electron/bridges/ai/shellUtils.cjs` narrowly recognizes Oh My Zsh ys two-line idle prompts (#4008/a0cf2b48) |
+| 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.

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.
