+# 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.

-# 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
-`36993b1d566814d3b5304337fab73ff464e422d93ba52909e95e3ceedcad2a6a`.
-Two independent package builds matched. Build scripts and tests are excluded
-from the six-file installed package.
-
-## 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

-## 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.

+# 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.

-# Global Agent Chat example (work in progress)
-
-This browser sandbox plugin provides a custom Chat view using the existing
-host-owned Agent runtime. Choose a configured Catty or Claude Code backend,
-explicitly choose connected terminal targets, open a new or owned conversation,
-then Send. Stop cancels the exact turn. Refresh and reselection are explicit;
-expired authority never silently re-shares targets or retries inference.
-
-Core stores source-isolated conversation history. The plugin receives text,
-usage and safe activity summaries, never native session IDs, credentials, raw
-tool arguments/results or executable/MCP configuration. Tool actions use the
-plugin's `ai.agent.actions` Allow / Ask / Deny setting. Other backends report
-unsupported/unavailable until their native tool boundaries are verified.
-
-Build with `node examples/plugins/global-agent/build.mjs`, then package the
-`.package` directory using `@netcatty/plugin-cli`. Install the resulting `.ncpkg`
-through Settings → Plugins. This is a minimal example, not a background service.
-Real provider/Claude usage requires a user's already configured backend and
-separate approval for paid acceptance testing. Automated tests use synthetic
-fixtures and do not establish authenticated Claude service/native acceptance.
