docs(plugins): clarify default directory enumeration boundary

The two-line idle prompt check only accepted a classic user@host host
line, so Oh My Zsh ys (`# user @ host ...` then a bare $/#) never became
ready and terminal_execute sent nothing. Match that host line narrowly
and still reject a lone marker.

Fixes #4007

+# 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.

+## Preserved inputs
+
+| Input | Exact checkpoint | Integration |
+| --- | --- | --- |
+| Frozen integration | `677aac33b1eec9dbd4a367417a49c964cdea63e7` | Starting point; includes stream/source/Host/settings and prior terminal history |
+| Permission policy #4000 | `79a9bd6df1c17fd8a5238aba31d7a8b4cda184b9` | Initial ordinary merge `9aa899059` preserved 2eee561; follow-up ordinary merge `cfa13680e` preserves the authoritative scope/sensitivity copy and tests |
+| AI #3986 | `d33c0193ccaedc1a10aed9da495f040250121bef` | Ordinary merge `5d2ff1cb8`; cold-start wiring, themed sample and Node 22 warning-drain test correction |
+| Terminal production | #3996 `8e7c28fe1bdbcdd76816d33ec926ba8e60eefe64` | Preserve the prior renderer eligibility/publication path; policy-owned interaction changes remain from #4000 |
+
+Diagnostic #3999 and its tests/docs-only `3fdaa357` continuation are not merged.
+No terminal runtime fix is required by the fixture-classification finding.
+Database protocol and fixed SQL remain solely in the minimal examples.
+
+## Direct integration decisions
+
+The initial merge conflict was `components/PluginAIContextHost.test.tsx`. The
+combined test keeps policy's absence of a second native content-sharing review
+and AI's actual main allowlist, two-provider synchronization, streamed result,
+Stop/lock cleanup and empty SDK-error assertion. The Node 22 warning drain is
+retained. The obsolete forced-review cancellation branch is superseded by the
+current in-app Ask/cancellation tests; no transport assertion is dropped.
+
+No production file needed a manual conflict resolution. Policy production files
+remain identical to the policy input; the three AI startup wiring files and
+sample assets remain identical to d33c0193. The stream service/router and prior
+terminal renderer eligibility/publication files are unchanged from frozen 677.
+
+Integration commit `7d8a354404d68071d0924532ffe74c713ace6cb9` updates two stale
+disclosure assertions in `PluginPackageManager.test.tsx` and
+`PluginMarketplace.interaction.test.tsx`. They expected the old words
+`not a grant`; the new assertions require default Allow, Ask/Deny controls and
+retained host validation/resource scope. Existing escaping, advanced-authority,
+source and README-failure assertions remain intact. Production copy is unchanged.
+
+The later authoritative 79a9bd6 policy merge overlapped those two tests. Their
+final contents are byte-identical to 79a9bd6: all three earlier policy assertions
+remain, together with the owner's additional unbounded-resource, sensitivity,
+escaping/source-order and advanced-authority checks. No assertion was dropped.
+This follow-up imports the owner's five-locale wording changes; it makes no
+manual production conflict edit and leaves the shared AI test intact.
+
+## Checks and retained failures
+
+| Local check | Result |
+| --- | --- |
+| Registered runtime | 695 tests: 694 passed, one native skip, zero failed/cancelled |
+| Contract/SDK/CLI | 91 passed |
+| Offline examples | Five passed, one explicit Docker opt-in skip |
+| Serial mounted AI/permission/selected-summary/Host/provider/panel group at 7856 | 31 passed |
+| Final settings, terminal interaction, cold-start host and locale group | 90 passed |
+| Contract/capability/Codex generation and drift | Passed |
+| Full lint | Zero errors, seven existing warnings |
+| Production build | Passed; Vite 35.50 seconds |
+| Five sample archives | Validated; repeat builds byte-identical |
+
+The initial settings group records 34 passes and two failures on the stale copy
+assertions. That run is retained separately from the corrected 36/36 result.
+
+Policy input [test CI 40443396430](https://github.com/binaricat/Netcatty/actions/runs/40443396430)

+
+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.
