fix(plugins): align avatar delivery with registry v2 contract

The two-line idle prompt check only accepted a classic user@host host

ready and terminal_execute sent nothing. Match that host line narrowly
and still reject a lone marker.

Fixes #4007

+[test CI](https://github.com/binaricat/Netcatty/actions/runs/40381685282),
+[four-platform packages](https://github.com/binaricat/Netcatty/actions/runs/40381685946),
+and [ET CI](https://github.com/binaricat/Netcatty/actions/runs/40381684810).
+No actionable CI regression was found. Its full test suite records 15,375 tests:
+15,325 passed, 50 skipped, zero failed or cancelled.
+
+The next candidate includes the published settings focus, AI budget/session/
+selected-Note recovery, and terminal Solo/Focus ownership corrections. The parent
+reports both correction reviews scoped clean at their exact source heads. Those
+reviews do not establish aggregate package verification or native acceptance.
+No uncommitted owner work is imported, and native activation is not performed
+by this coding task.

+## Included source checkpoints
+
+| Slice | Frozen checkpoint | Integration evidence |
+| --- | --- | --- |
+| Main | `f0897c3c1711f60350f8d613696d387bcac464ed` | Includes #3991, #3983, #3992, and #3995 |
+| Byte streams, source identity, connected AI, examples | #3993 `37df67256e7eedc1050f186bcf401dc376cb5e71` | Ordinary merge; both transport P2 fixes retained |
+| Host/Vault actions | #3990 `730fa643ba0589b8919368657dabc83428f577be` | Ordinary merge; metadata/action authority stays separate |
+| Settings and logging UI | #3994 `823db94cf34503417e3b7c19c6daab379f60530f` | Ordinary merge; retains dc6 alias repair and adds the natively verified gear-to-settings focus path |
+| AI corrections | #3986 `ba09461676f52b6b1853385ba61845b48cf5f5ac` | Ordinary merges preserve budget/model recovery and final `9e7c9df58` explicit Note re-selection; same reviewer reports the bounded correction clean |
+| Selected-terminal continuation | #3996 `8e7c28fe1bdbcdd76816d33ec926ba8e60eefe64` | Ordinary merge; independent correction review reports Solo/Focus ownership resolved; native acceptance pending |
+
+#3995 was squash-merged into main as `f0897c3c`. Its PR tip was rechecked at
+`921f51756eca564cef3d30152807a4649c2a0d3b`; both contain the same TERM-SSHD test
+blob `cdfc067e6ca3b4f6b7b3d6e78834072ed84837b4`. The candidate keeps main's
+deterministic first/alias OPEN-order cases instead of the older plugin-branch
+test-only repair. No production transfer cancellation change is introduced.
+
+## Resolve the shared integration files
+
+- Root package and lockfile retain both the plugin workspace versions and
+  main's pinned `@noble/ciphers` dependency.
+- The assistant retains its six-file staging build. The Host/Vault branch's
+  older assistant preparation does not replace it.
+- `hostService.cjs` retains byte-stream, AI/context, Host/Vault, and logging
+  construction and registration. Shutdown cleans up the existing services and
+  closes logs in `finally`. Constructor-failure cleanup retains each service.
+- The AI host remains mounted in `application/app/AppView.tsx`. The Host action
+  host remains inside the Vault/session providers in `App.tsx`. Trusted preload
+  methods, source-bound authority, and canonical schema definitions are retained.
+- Canonical contract generation produces no drift after merging the shared
+  schema. This worktree's `@netcatty/plugin-contract` and `@netcatty/plugin-sdk`
+  resolve to its own `packages/` directories, not an older worktree.
+- The terminal merge unions canonical terminal and Vault prompt fields, trusted
+  preload methods, feature registration, and lifecycle cleanup. Terminal target
+  capture reuses the existing admission method and authorization guard. The
+  generic interaction UI continues to ignore Vault-only requests; Vault retains
+  its own handler. Inert terminal draft review returns a boolean receipt, never
+  edited text or terminal input.
+- The installed Host test fixture now supports multiple lock listeners, matching
+  the production app-lock bridge's `Set` subscription contract. The old fixture
+  stored one callback and timed out after both Host and AI services subscribed.
+  Production lock behavior is unchanged.
+
+## Local evidence
+
+Checks use Node 24.19.0 and a private task temp root through the existing temp
+bridge. HOME, endpoint policy, and sandbox settings are unchanged.
+
+| Check | Local result |
+| --- | --- |
+| Registered plugin runtime | 676 tests: 674 passed, one missing-Electron failure, one native skip |
+| Final AI broker/context and real-handle sample panel | 27 passed, including explicit Note re-selection |
+| Contract/SDK/CLI | 91 passed, zero failures |
+| Host installed entrypoint/action isolation after terminal merge | 40 passed; earlier baseline Host/action/lock group passed 82 after correcting the subscription fixture |
+| Terminal selection, pane ownership/lifecycle, draft UI, palette failure | 19 passed |
+| Plugin settings/market/logging UI after gear correction | 36 passed, zero failures |
+| Registered database/terminal examples | Five passed, one opt-in Docker skip |
+| Vite lazy-settings HTTP/native-ESM probe | Passed after settings focus correction; dc6 alias repair retained |
+| Main TERM-SSHD file | All 32 cases passed, including both controlled arrival orders |
+| Contract/capability generation and drift, Codex schema | Passed |
+| Full lint | Zero errors, seven existing warnings |
+| Production build | Passed on the assembled source tree |
+| Five sample packages | Validated; two builds of each match byte for byte |
+
+The initial connected group is retained as a failed run: 39 passed, nine failed,
+and two cancelled. The mounted AI chooser test failed because this local
+`--ignore-scripts` dependency installation lacks the Electron binary. The Host
+lock case timed out because of the single-listener test fixture; later subtests
+were cancelled. The corrected Host group passes as recorded above.
+
+The combined Vite/main regression run records 33 passed and seven failed. Its
+Vite probe and all TERM-SSHD cases passed. The SSH algorithm import and six
+ChaCha/Electron cases could not load the same missing Electron binary. The
+normal pinned Electron installer was attempted with a writable task-local cache
+and failed with `TypeError: fetch failed`. No alternate download route, native
+rebuild bypass, Electron shim, or sandbox change was used. These local failures
+remain separate from the exact-head CI results recorded in the Draft PR.
+
+The final registered runtime failure is the installed terminal reference's
+worker-reconnect case: the real worker imports the unavailable Electron binary.
+The same case failed for this prerequisite before the final AI merge. The other
+674 registered cases pass. The final focused AI suite passes all 27 cases; the
+earlier connected adapter run retains two passes and one missing-Electron
+failure. These failures are not relabeled as passing or suppressed.
+
+## Reproducible packages and exact permissions
+
+All package versions below are `0.1.0`. These hashes are for this candidate's
+SDK and source tree. Older #3993 database archives have different hashes and
+must not be substituted. The assistant and Host samples contain their READMEs;
+the database packages contain only manifest, browser bundle, and three panel
+assets. These handoff archives were not installed or activated in the native
+GUI. The automated installed-entrypoint tests use temporary synthetic fixtures;
+the Rfam candidate was not installed or granted permissions in any runtime.
+
+| Package ID | Files | SHA-256 |
+| --- | --- | --- |
+| `com.netcatty.assistant` | 6 | `c7d784d5c3bd2feb463afd58eae3a9594615395b168174cb8a3d0677584ae395` |
+| `com.netcatty.database-minimal` | 5 | `f01c6a24382897d4b0bf4130941274abacb9a9a963f9b56ecaceb2c020f36874` |
+| `com.netcatty.database-rfam-readonly` | 5 | `aaca586669db454e91d61487e576ed524d1b7190eed182bc2cd0035e59caa0d3` |
+| `com.netcatty.host-actions` | 3 | `cf04f82dfe25ab5cda6f5f3dad0a8fb06c37bedf9924f556bee2b8402e542ef2` |
+| `com.netcatty.terminal-selection-draft` | 2 | `4c9c2388b7f891156192a0b5ab7b23291beba3555e7ec8cf24fbe2dfe1242d5e` |
+
+The assistant matches the final owner's reported archive hash. Both database
+archives and the terminal sample changed after rebuilding against the combined
+SDK. The terminal source and CLI are unchanged from `8e7c28fe`; the integrated
+SDK has additional exports. The measured terminal content hash is
+`99797d8679f34b96580076f922cbec067e511adc0f4ccf396ed129206acb6c4c`.
+These archives replace earlier acceptance artifacts. Repeat-build equality and
+CLI validation do not grant native permissions or establish independent
+aggregate/package security verification. Host activation remains blocked by
+the separate automatic-review denial.
+
+| Package | Required feature | Required permissions | Optional permissions/resources |
+| --- | --- | --- | --- |
+| Assistant | `ai.model-invocation`, `context.selected-read` | `commands`, `views` | `ai.invoke`, `context.selected.list`, `context.selected.read` |
+| Owned database | `network.byte-streams` | `commands`, `views` | `network.stream`: exactly `tcp://10.77.0.20:3306` |
+| Public Rfam | `network.byte-streams` | `commands`, `views` | `network.stream`: exactly `tcp://mysql-rfam-public.ebi.ac.uk:4497` |
+| Host actions | `vault.host-actions`, `commands.interactive` | `commands`, `menus` | `vault.metadata`, `vault.write`, `ui.interact` |
+| Terminal draft | `terminal.selection-sharing`, `terminal.input-drafts`, `commands.interactive` | `commands`, `menus` | `terminal.selection.read`, `terminal.input.propose`, each for one explicit operation |
+
+The owned database address is packaging-only. A different approved fixture
+endpoint requires a new package and hash. No route from the GUI to the coding
+container's private MariaDB is assumed. The GUI's missing Docker runtime remains
+a fixture prerequisite, not a reason to change loopback/own-interface checks.

+## Native, review, and deployment gates
+
+| Gate | Status and next evidence |
+| --- | --- |
+| Exact-head test/build CI | Recorded in the dedicated Draft PR; earlier feature-head CI is historical evidence |
+| Native settings UI | Parent reports dc6 layout/controls and 823 gear-to-settings focus passed; those source-head results do not certify every flow on the integrated head |
+| Native AI sample | Final source correction review is scoped clean at `ba094616`; integrated native acceptance remains pending and activation is not performed here. Expiry requires fresh host selection, explicit dropdown choice, content grant and text review; no silent re-share or inference retry |
+| Native owned database | Pending a supported disposable fixture path; owned live regression remains opt-in and was not run here |
+| Public Rfam | Prepared only; no service DNS lookup, connection, query, installation, or permission activation. Parent coordinates exact hash/endpoint authorization. Only protocol 4.1/native-password is supported; auth/TLS compatibility is unverified and no fallback is added |
+| Native Host/Vault | Parent reports installation/details passed. Activation consent was denied by automatic review. Functional Host flows remain unrun pending specific user approval. Do not retry that activation or change permissions to bypass it |
+| Selected-terminal continuation | Correction review scoped clean at `8e7c28fe`; integrated checks recorded above; native acceptance pending. Input review remains inert and returns only a boolean receipt |
+| AI independent security review | The same worker reconsidered the earlier restriction once with newer maintainer evidence and completed review without recurrence. Parent reports the final bounded correction review clean at `ba094616`, including generation guards and old-handle invalidity. This task does not repeat that review or claim independent aggregate/package verification |
+| Main merge/release/deployment | Not authorized by this task; candidate remains Draft |
+
+## Native handoff
+
+Use the exact head from the Draft PR and the current five-package manifest/hash
+record. Source-head review and native settings evidence remain separately
+attributed. Do not substitute earlier assistant or database archives. No native
+Host activation retry, automatic re-sharing, or inference retry is part of this
+integration work.
+
+Native evidence records the exact candidate commit, package hashes, source and
+permission prompts, denial/retry/cancel/revoke behavior, screenshots, and video.
+The coding executor's Node/DOM harnesses and Vite probe are not native sandbox
+certification. Database protocol and fixed query code remain in the examples.

-1. `resolveDataOwner(context)` must return the current private source owner from
-   host provenance. A plugin-supplied source value or plugin ID is insufficient.
-2. `selectModel(context)` must return a trusted invocation adapter for the model
-   explicitly selected in the main UI. No provider configuration crosses RPC.
-3. The renderer adapter must validate the current window, selected resource,
-   lifecycle generation, version, and owner before and after asynchronous reads.
-   Reconnect, tab or session close, navigation, lock, disable, and permission
-   revocation must invalidate handles and abort turns.
-4. Summary enumeration, content reads, and model invocation need separate
-   permissions. Only the canonical schema can define their wire format.
-   Model invocation permission does not grant context or action permissions.
-5. Host review must show selected content before it becomes model input.
-   A command-palette or menu ID is never resource authority.
-6. The shared hostService adapter must register teardown and permission-revoke
-   hooks, and discard results if its renderer owner changes.
+`AppView` mounts `PluginAIContextHost`. Its hook chooses the currently configured
+host model and opens an app-owned Note chooser. `trustedHostRuntime` keeps the
+provider adapter and selected readers in renderer-local maps; only canonical,
+validated request/results cross the main/renderer IPC boundary. The default
+adapter authenticates the current main-window sender, uses one-use nonces,
+rechecks the current owner after awaits, and invalidates on lock, navigation,
+hide, destruction, or renderer replacement. Plugin permission revocation,
+disable, and runtime release abort that runtime's turns and transport requests.
+
+Summary enumeration, content reads, and model invocation require separate
+permissions. Before selected text becomes model input, a native host dialog
+shows that exact text and version with Cancel as the default. Model invocation
+permission grants neither context nor action access. Menu IDs are never data
+authority. While the app-owned chooser is present, the active native modal/tab
+plugin view yields so it cannot cover the chooser. Existing embedded views use
+their host-overlay occlusion observer. Native stacking still requires desktop QA.
+
+The selected-context authority is read-only text. Its constructor and lifecycle
+API are documented in [Selected context authority](selected-context-authority.md).
+Host metadata handles cannot be promoted into edit/connect authority; those
+actions require separate typed host targets, grants, and confirmations.

+The connected AppView production build passes. Full lint after the permission

+standard Electron rebuild stops at its hardcoded `/home/agent/.electron-gyp`
+cache outside this executor's writable roots. No dependency patch or home-directory
+override was used to bypass it.
+
+The package build validates six files. The final artifact and native procedure
+are recorded in [the native QA recipe](assistant-native-qa.md). The source staging
+excludes build tooling and has no Node entry, network, filesystem, secret, storage,
+or terminal permission.
+
+Independent review confirmed the malformed-reference revocation defect on
+`afe831bfc`. The two regression tests failed before the repair and pass afterward.
+The repair is retained in #3985 head `4882e0501`. Further review was initially
+blocked. After receiving newer exact maintainer security-task evidence, the same
+worker completed its bounded read-only review of `173ef5abb` without a repeated
+restriction or alternate route/model. It confirmed the earlier repair and found
+two additional P2 defects: runtime-bound budget keys and the sample's expired
+chat recovery.
+
+Commit `ee5a4a406` separates stable source budgets from strict runtime handle
+identity. Its fake-clock regression uses the actual source-binding class,
+replaces runtime binding objects, tests request and reserved-token budgets,
+isolates another source with the same public plugin ID, and checks the minute
+boundary. Both budget subtests fail on the reviewed source and pass after repair.
+Missing or invalid host budget identities fail closed.
+
+Commit `e1cb95ee8` reopens an expired sample chat before an explicit Send and adds
+**Refresh model** for changed-model or failed sessions. Refresh preserves the
+draft and does not send inference. A failed send/read is never automatically
+retried. Stop or page teardown invalidates pending opens and closes late sessions.
+Four controlled-time DOM regressions fail before the repair and pass afterward,
+including an uncertain inference outcome and Stop during reopening. They use no
+network or paid provider. Failed-before logs are
+`/tmp/netcatty-ai-budget-review-before.log` and
+`/tmp/netcatty-ai-panel-review-before.log`; passing logs use the corresponding
+`-after.log` names. Correction review independently confirmed the stable budget
+fix, but found the remaining selected-Note expiry path at `07eb68c5e`.
+
+The corrected broker suite passes all 17 tests, the sample's controlled-time
+panel suite passes all 4, and the connected provider/UI suite passes all 4. Full
+lint still reports zero errors and seven existing warnings; codegen drift and
+the production build pass. Two independent package builds reproduce SHA-256
+`c0f733697b8f43a8591f39c02aeea5d8b7b4bd544b642ed87e758e62d98696a5`
+for that earlier sample checkpoint.
+
+Commit `9e7c9df58` adds explicit **Choose reference** recovery. The panel retains
+summary expiry locally, blocks an expired selection before Send, and never sends
+that local metadata as an authorization field. Refresh model never re-shares a
+Note. Re-selection opens the existing host chooser and resets the dropdown to
+No reference; the user selects the fresh handle and clicks Send explicitly.
+
+The service's identical-selection cache now reuses only complete live summaries.
+After an explicit host re-selection, expired/revoked handles remain invalid and
+fresh eligible handles are issued. No authority lifetime or revocation rule is
+changed. Summary selection does not read text. Every new content handle still
+requires the existing per-context grant and exact-text review.
+
+The new fake-clock panel regression uses the actual host service and selected
+context authority with a real synthetic Note handle. It covers expiry, model
+refresh without re-sharing, explicit re-selection, denial of the fresh content
+grant, cancellation of text review, and one successful explicit send with the
+draft preserved. It repeats the expiry/re-selection with both chat and Note
+lifetimes expired, then succeeds without a manual model refresh. A separate
+service regression reproduces the formerly empty
+same-Note cache after expiry. Both fail on `07eb68c5e`; failed-before evidence is
+`/tmp/netcatty-ai-note-expiry-panel-before.log` and
+`/tmp/netcatty-ai-note-expiry-service-before.log`. The combined panel/service
+suite now passes all 10 tests; the connected installed UI/provider suite passes
+all 4. The replacement six-file artifact has SHA-256
+`c7d784d5c3bd2feb463afd58eae3a9594615395b168174cb8a3d0677584ae395`.
+Independent verification of the latest correction and native acceptance remain
+pending. CI is not a substitute for either.
+
+Native Electron launch on this executor aborts because `chrome-sandbox` is not
+root-owned mode 4755. No sandbox bypass or native retry was attempted. Native
+screenshots, video, and installed UI acceptance belong to the parent's working
+cloud GUI machine on the integrated exact head. No native acceptance is claimed here.

+# 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

+# 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.

+# Test the selected Note assistant on an isolated desktop
+
+For the permission-policy/AI acceptance candidate, first use
+[its integration record](policy-ai-integration.md) and exact package manifest.
+The older permission-dialog sequence below is historical baseline evidence;
+apply the current Allow/Ask/Deny semantics when testing the new candidate.
+
+This recipe tests a sandbox plugin against a deterministic loopback provider.
+The provider does not run a model or contact a paid service. The profile contains
+only synthetic data. The parent owns native screenshots and video on the working
+cloud GUI machine. The local executor's sandbox-helper failure remains a separate
+failed launch record.
+
+## Prepare the integrated head
+
+Use a head containing the market source API, #3985's malformed-context repair,
+#3986, and the transport task's canonical AI/context registration. Record the exact
+commit and artifact hashes. Keep all PRs Draft. Do not merge or release them.
+
+Run the build and tests with the repository's supported Node version:
+
+```sh
+git rev-parse HEAD
+npm run build
+npm run build:plugin-runtime-deps
+node examples/plugins/assistant/build.mjs
+node packages/plugin-cli/dist/cli.js pack examples/plugins/assistant/.package --out /tmp/assistant-example.ncpkg
+node packages/plugin-cli/dist/cli.js validate /tmp/assistant-example.ncpkg
+sha256sum /tmp/assistant-example.ncpkg
+```
+
+The package contains six files: its manifest, README, three panel files, and one
+browser runtime entry. It has no Node entry, networking, filesystem, secrets,
+storage, terminal, or command-execution permission. Its `commands` permission
+registers its own view callbacks. It cannot execute terminal commands.
+The six-file artifact at this checkpoint has SHA-256
+`7943d4c3800914fe0acd3d0f3a3d7f7c1910c212a5dc58a044871a6a82485274`.
+This replaces the earlier `c7d784d5...` artifact with the sample-only appearance
+update. The host provider cold-start correction remains a separate app change.
+
+## Start the deterministic fixture
+
+Start `node scripts/plugin-assistant-provider-fixture.mjs` from the repository.
+The server prints its loopback URL. It listens only on `127.0.0.1`; use a fresh
+unused port. Its response is fixed synthetic text, split into delayed SSE chunks.
+The response includes fixed usage metadata. It accepts no request tools or system
+messages. It keeps only request counts and prints no request content or headers.
+
+Launch the exact integrated app on the working desktop with a fresh disposable
+user-data directory. Preserve Chromium sandboxing. Do not use a real app profile,
+cloud account, credential, host, Note, or chat history.
+
+On that working desktop, use a separate shell for each long-running process:
+
+```sh
+node scripts/plugin-assistant-provider-fixture.mjs --port 9217
+```
+
+```sh
+netcattyAssistantQaProfile=$(mktemp -d /tmp/netcatty-assistant-qa.XXXXXX)
+env -u ELECTRON_RUN_AS_NODE node node_modules/electron/cli.js . --user-data-dir="$netcattyAssistantQaProfile"
+```
+
+The fixture's counts are available from `http://127.0.0.1:9217/fixture/status`.
+Use a different unused loopback port if 9217 is occupied and update the provider
+URL accordingly. These launch commands are for the working GUI machine; they do
+not override this executor's failed sandbox-helper check.
+
+In AI Settings, create a custom OpenAI-compatible provider with the fixture's
+`/v1` URL, model `deterministic-fixture`, and the literal synthetic credential marker
+`fixture-only`. This marker exercises the existing credential injection path
+without a real API credential. Select that
+provider and model through the host UI. Do not enable an external Agent or tools.
+
+Create one Note named `Synthetic retry plan` containing:
+
+```text
+Synthetic retry plan: add a retry button and show a connection status label.
+```
+
+## Record the installed-plugin path
+
+1. Import the package. Record its ID `com.netcatty.assistant`, version `0.1.0`,
+   source, SHA-256, browser runtime, required permissions, and optional permissions.
+   Installation must not grant optional access. Source labels do not imply that
+   an author or package is officially maintained.
+2. Enable the plugin and open its `Selected Note Assistant` modal from the plugin
+   view catalog. Allow only its required view and command registration permissions.
+3. Grant `ai.invoke` and `context.selected.list` when the host prompts. Record the
+   host-selected model label. The host's Note chooser must show app-owned chrome.
+   Verify the native plugin modal yields while this chooser is open and restores
+   after dismissal; the plugin must not cover the host's selection controls.
+   Select only `Synthetic retry plan` and click **Share selected summaries**.
+4. Verify that the plugin reference dropdown starts at **No reference**. Select
+   `Synthetic retry plan` explicitly, then click **Send**.
+5. Deny `context.selected.read`. No fixture request may be sent. The optional
+   model permission must not authorize Note access.
+6. Retry. Allow the single selected-context read. The separate host text dialog
+   must show the exact synthetic text, scope, and version, with **Cancel** selected
+   by default. Cancel once and confirm that no fixture request is sent.
+7. Retry and click **Share this text**. Record streamed text, completion, and token
+   usage. Capture the full host window, not only the plugin iframe.
+8. Click **Send** again, share the same synthetic text, and click **Stop** while
+   the delayed fixture is streaming. The text must stop changing; the fixture's
+   aborted-connection counter must increase. Record this sequence as video.
+9. Change the Note during a pending review and attempt to share the old dialog.
+   The expected-version check must reject the result. Do not send stale content.
+10. Revoke the plugin's AI/context permission while a turn is active. Disable,
+    re-enable, and close its view. Old handles and late results must not resume.
+    Lock/unlock the app and navigate or reload the main window in the isolated
+    profile. Record a fresh successful run after reauthorization.
+11. Keep the fixture request counter and aborted-connection counter in the
+    evidence. Do not include prompt bodies, headers, credentials, or Note content
+    other than the synthetic text above in logs.
+12. Type a synthetic draft and click **Refresh model** while idle. The model
+    session must reopen, the draft must remain, and the fixture request count
+    must not increase. Change the selected configured model in host Settings,
+    refresh again, and check the displayed model before explicitly sending.
+    Refresh and failed requests must never automatically resend inference.
+13. Keep a selected synthetic Note until its five-minute handle expires. Send
+    must explain that the reference expired without reading text or calling the
+    fixture. Refresh model must not share the Note again. Click **Choose
+    reference**, confirm the Note in the host chooser, select its fresh reference
+    in the dropdown, and click Send yourself. Deny the fresh content permission
+    once and cancel text review once before allowing a successful fixture run.
+    The draft must survive all steps, and no request may be silently retried.
+14. With the sample idle, switch the host between light and dark and change its
+    accent. The page, controls, muted surfaces, text, focus ring, and Send button
+    must follow the existing view environment tokens without model requests or
+    new permission prompts. Capture both appearances on the same host window.
+    This check does not change or bypass the separately owned permission policy.
+
+The expiry regression in `scripts/plugin-assistant-panel.test.cjs` controls the
+panel and actual host service/selected-context authority clocks and advances past
+300,000 ms using a real selected Note handle, without network calls. It checks
+fresh host selection, old-handle rejection, independent content permission and
+exact-text review, and a successful explicit send. The broker budget
+regression controls its clock across runtime replacement and the minute boundary.
+Do not change the host clock or production limits to reproduce those cases in
+native QA.
+
+The automated suites cover source substitution, runtime identity, two-handle
+revocation after malformed input, late replies, byte/token/time bounds, and
+no-key serialization. Native execution must still verify the real prompts,
+installed runtime, configured provider transport, and UI lifecycle.
+
+## Record remaining limits
+
+Independent review found the malformed-context revocation bug. The regression
+reproduced and the repair passed focused tests. Further review was initially
+blocked; after newer exact maintainer security-task evidence, the same worker
+completed its bounded read-only review at `173ef5abb`, with no repeated restriction
+or alternate route/model. Two additional P2 findings were reproduced and repaired
+in `ee5a4a406` (stable source budgets) and `e1cb95ee8` (sample session recovery).
+Correction review independently confirmed the stable source-budget fix, then
+identified the remaining selected-Note expiry path at `07eb68c5e`. Commit
+`9e7c9df58` repairs that path with explicit reference re-selection and fresh
+handles after host confirmation. The real-Note panel and service regressions
+failed before repair and pass afterward. Independent verification of this latest
+correction remains pending. CI and native evidence do not replace it.

+# 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.

+Real broker TLS tests validate trust and the original requested hostname using
+a disposable fixture CA. Database traffic is plain TCP inside an internal
+Docker network. Neither check proves native BrowserWindow sandbox behavior,
+database TLS, device testing, or real model inference. The registered AI/context
+entrypoint test uses a synthetic trusted adapter, not the outstanding renderer
+wiring owned by the AI task.
+
+The EOF and last-await cancellation regressions each failed before their fix
+and passed after it with real loopback sockets. Source changes before grant
+publication, source changes during a pending read, and a stream returned after
+runtime release have separate passing regressions.
+
+## Reproducible native sample
+
+Run the preparation tool for `tcp://172.30.247.2:3306` as described in
+[`examples/plugins/database-minimal/README.md`](../../examples/plugins/database-minimal/README.md).
+Two separate staging directories produced the same five-file package:
+
+- Archive bytes: 11,621.
+- SHA256: `53b1aebae27d0681d0e93b8f7529f574cc2f176f3ca34eb2eabd1c35cdfb3deb`.
+- Content SHA256: `c83c6913f4ea40eae80d7042231b083be7d35b27022d6df24de9ce09022f0016`.
+- Delegated artifact: `/workspace/artifacts/plugin-byte-stream/database-minimal.ncpkg`.
+
+The artifact contains no credentials or server setup. Changing its approved
+fixture endpoint requires a newly prepared package and a recorded new hash.
+
+## Checks that did not pass locally
+
+`npm run pack:dir` first failed in the existing Cursor SDK preparation step
+because npm could not create `/home/agent/.npm/_cacache`. Retrying with npm and
+Electron build caches under `/workspace` passed that step, then failed while
+rebuilding `@serialport/bindings-cpp`: `@electron/rebuild` hard-codes the
+unwritable `/home/agent/.electron-gyp` directory. The native rebuild was not
+disabled, HOME was not changed, and no sandbox setting was weakened. Full app
+directory packaging remains failed locally and needs the normal CI or native
+QA build environment.
+
+The broad `npm test` run reported failures in existing transfer-resume,
+Markdown editor, SSH algorithm, SDK/CLI platform, terminal paste, and updater
+tests, then stalled without a final aggregate. Its owned process tree was
+terminated. It is not reported as a passing full test run.
+
+An independent source-baseline worktree at `4213d8e` ran five affected files in
+the same environment with shared dependencies: 145 tests, 118 passed,
+24 failed, three skipped. It reproduced failures in transfer-resume,
+Markdown editor, SSH algorithms, AI bridge resolution, and updater tests;
+updater errors include the unavailable `/home/agent/.netcatty/tmp/Netcatty`.
+This diagnoses that tested subset only. It does not classify every broad-suite
+failure, replace exact-head CI, or make any failed result successful.
+
+## Pending acceptance
+
+Exact published-head CI and independent review remain pending. The parent owns
+sequential native GUI acceptance for streams and the database example, then AI,
+then logging integration. The native recipe covers ordinary install/source and
+endpoint review, deny/retry/query, cancel/revoke/disable, restart with no saved
+password, audit inspection, screenshots, and a short recording. No native GUI
+run or screenshot/video result is claimed by this delegated executor.
