-# Plugin author presentation
-
-The marketplace displays the catalog's author next to a small avatar. Installed
-views reuse the author row. Missing, loading, unavailable, or invalid imagery
-uses a bundled placeholder. An avatar is presentation metadata, not proof of an
-authenticated GitHub publisher.
-
-The registry binds an image to its reviewed displayed-author subject. Repository
-ownership alone does not establish that subject. The current first-party author
-is the Netcatty project, not an assumed personal GitHub identity. Until an image
-pin is reviewed, its avatar remains null.
-
-## Avatar delivery
-
-Delivery v2 extends the reserved `avatar` field to null or
-`{path, sha256, size}`. The path is exactly `/assets/<sha256>.png` or `.webp`.
-Size is a positive integer no greater than 256KiB. The delivery digest and existing
-id/version/repository/commit tuple bind the reference. Catalog and index identity
-fields do not change. Source-only delivery v1 remains supported.
-
-Only the main process fetches the selected source's same-origin asset. Existing
-URL, credential, redirect, timeout, byte-count, and SHA-256 checks apply. The host
-rechecks the source and selection after asynchronous work. The existing isolated
-icon rasterizer validates and converts PNG or WebP to a bounded PNG data URI,
-using its current queue, pending-work map, and cache. No renderer URL, arbitrary
-file path, GitHub API, or GitHub avatar URL is accepted. Visible rows load lazily.
-
-Installed presentation uses already validated catalog metadata only when source,
-version, package digest, and manifest match the active installation. It does not
-fetch a catalog just because the installed list opens. Without an exact match,
-the declared publisher and placeholder remain visible, without a maintenance
-badge. No installed-data migration or persistent identity cache is added.
-
-## Official maintenance
-
-The borderless gold pill means that the Netcatty project maintains the plugin.
-It does not certify the plugin's safety or grant permissions. It is separate
-from the official marketplace source label.
-
-The main process requires the built-in official source and one of these explicit
-first-party ID and repository pairs:
-
-- `com.netcatty.starter`, `binaricat/Netcatty`
-- `com.netcatty.hello`, `binaricat/Netcatty`
-
-A local import, a third-party copy, an ID prefix, author text, manifest publisher,
-README, or membership in the official marketplace cannot create this badge.
-The renderer consumes the host result through the existing trusted-app IPC
-boundary. No new plugin permission or plugin RPC is introduced.
-
-## Validation scope
-
-Focused registered tests cover source spoofing, exact installed identity,
-hash-bound images, invalid metadata and decoding, redirects, source removal,
-selection changes, cache reuse, lazy loading, stale UI cleanup, placeholders,
-and borderless light/dark theme classes. These tests do not establish native
-layout, actual account identity, live CDN deployment, or successful network access.
-Actual app screenshots and native acceptance remain separately scheduled.

-The separately published icon branch first reverted its outline correction
-(`530ff0318`), then the e4 row commit (`6e4465f47`). Neither outline correction nor
-those isolated reverts are imported here; foundation never included the outline.
-The e4 and 1f renderer artifacts are historical pre-cancellation evidence, not
-accepted final UI. No further cancelled-design build or screenshot is requested.
-
-The only manual merge conflict was the end of `index.css`. Resolution retains
-both the prior host-security theme block and main's window-background-blur block,
-with their declarations unchanged. Automatic combinations retain main appearance
-wiring alongside plugin settings/theme wiring, all five locales, preload methods,
-the host services and SDK exports. No permission, source, endpoint, sandbox or
-selected-resource restriction is relaxed. Package and lock inputs are unchanged.
-
-`50fda9142` reuses the same selection-token comparison after an install-triggered
-catalog refresh, including an install rejected for a changed/withdrawn selection.
-The rejection is preserved; mounted authors no longer retain withdrawn enrichment.
-The regression makes no package download or execution. It also preserves the
-original synchronous unavailable-source rejection in `list()`: the first aggregate
-runtime run caught that b14 changed it into a Promise rejection. The assertion was
-not weakened. Corrected aggregate runtime: 711 pass, one native skip, zero failures
-or cancellations. The original failed run and fail-before regression are retained.
-
-## Checks and packages
-
-Registered runtime, SDK/contract, Settings and actual connected host entrypoints,
-changed-main MCP/appearance/editor regressions, example preparation, code generation,
-lint and the normal production renderer build are run on this candidate. Exact
-head, commands, counts and CI links are recorded in #4011. Package provenance is
-in [the bounded sample manifest](foundation-packages.json): each archive is built
-twice and whole-byte compared. Assistant is byte-identical to d40; Host changes
-only README wording, with manifest/entrypoint unchanged. Database-owned, Rfam and
-terminal archives change only `browser.js` minified bound identifier spelling.
-Rebuilding the same sources with d40's generated SDK/contract artifacts reproduces
-the exact old archive hashes. Parsing and normalizing lexical bindings yields
-identical ASTs for all three bundles; manifests, protocol and permissions do not
-change. Preparation does not connect, activate or query.
-
-Local checks at pre-restoration1f: runtime 711 pass/one existing native skip; SDK91; Settings and
-connected host/security78; changed-main MCP/appearance/editor71; examples five
-pass/one Docker opt-in skip. Contract/capability/Codex generation has no drift;
-lint zero errors/seven existing warnings; normal production build36.13s. These
-checks do not claim native UI, packaging or encrypted transport acceptance.
-Restoration-focused layout/author tests: six pass; changed-file lint and diff
-checks clean. Two broader Settings runs each had38pass/one PluginLogSettings
-file-entry failure, without a detailed assertion; that file alone passed. Their
-cause remains unclassified and both failed runs are retained. No production log
-change or baseline attribution is made. Every one of the six layout paths exactly matches b14; fourteen functional
-paths (identity/provenance, permissions, directory availability and sync included)
-remain byte-identical to1f. The five sample records remain unchanged. Pre-restoration1f exact CI completed:
-[test40505644082](https://github.com/binaricat/Netcatty/actions/runs/40505644082)
-records15,372pass/50skip/zero failures or cancellations on its successful retry;
-[packages40505644200](https://github.com/binaricat/Netcatty/actions/runs/40505644200)
-passed all four platforms with release skipped. Its original runner shutdown is
-retained. These results do not certify the restored head.
-
-An earlier coding-executor full suite timed out after 15 minutes: 31 failures and
-482 cancellations. Seven failures reproduced on unchanged d40; 24 were not probed
-on that baseline. They remain unresolved evidence, not assumed baseline failures.
-No additional long local full suite is used to conceal them. Clean-run exact-head
-CI is a separate aggregate check and does not diagnose that historical run.
-
-## Acceptance and landing order
-
-1. Foundation: keep #4011 Draft until integrated CI/review and affected native UI
-   acceptance settle. d40 Settings, Host/Vault policy, terminal A/B selection and
-   inert multiline draft isolation, and native chat split/drag ownership passes
-   are historical evidence at their stated heads. They do not certify this new
-   current-main merge tree. The e4/07b reference-driven row design is cancelled;
-   stop its native visual work. Restored layout retains author/avatar presentation.
-   Avatar/catalog behavior and the final install-refresh correction still require
-   their scoped review/acceptance; cancellation does not erase functional gates.
-2. Marketplace distribution: retain static-source identity and v2 delivery checks,
-   but track reviewed registry data, actual hosting/CDN and install/update/source
-   replacement/withdrawal acceptance separately. Current live source-only viewing
-   is not installation or deployment acceptance. Never weaken admitted-source or
-   destination guards to manufacture a pass.
-3. Global Agent: #4006/#4012 remain a separate later increment, with their own
-   scope, review, CI and actual sample smoke. #4002 is also separate.
-
-Historical integration vehicles #3967/#3989/#3993/#3997/#4001/#4004 are superseded
-as landing vehicles, not discarded contributions. Their ancestors and native
-receipts stay available. Unique source PRs remain intact; no premature closures.
-
-Directory enumeration is intentionally unavailable in the default production
-composition until a same-handle adapter exists. The advertised feature now tells
-SDK callers the truth; filesystem permission alone does not enable it. The new
-sync composition test proves local collect/apply/hydrate with real databases, not
-encrypted cloud transport or native cloud-account sync. A native compatibility
-transition needs two properly versioned builds; two 0.0.0 checkouts do not qualify.
-
-Public database acceptance remains blocked by the retained TCP refusal before
-protocol payload; the separately owned local fixture is pending. Source-policy,
-compatibility and database gates must be explicitly reconciled by the parent,
-not silently removed from requirements. Nested log-dialog overlap has source
-coverage but no normal native route in the tested UI. This is code-readiness work,
-not a claim that deployment, every original requirement or the whole project is
-complete. No main merge, Ready transition, release or live metadata publication.

+# Global Agent 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
+
+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
+
+- Canonical schema/SDK/runtime registration and the installed default host path.
+- Host-owned durable history and backend references, including backend switching.
+- Actual Catty and Claude MCP dispatch, policy and worker lifecycle regressions.
+- Synthetic streaming/cancellation fixtures; these are not real inference or
+  actual authenticated Claude service acceptance.
+- Installable minimal chat UI with backend and explicit target choice.
+- Standard CI, independent review and parent-scheduled native evidence. No GUI
+  ownership, merge or release is granted to this executor.

-
-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

-## 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.
