-# Buildkite pipeline for Codewhale.
-#
-# Why this file exists: the `codewhale-ci` pipeline's steps lived in the
-# Buildkite UI and ran a 67-second smoke test (`cargo fmt` plus two focused
-# crates). That is not this repository's CI, so a green Buildkite build proved
-# almost nothing. Steps belong in the repo, reviewable in the same diff as the
-# code they gate.
-#
-# Scope, stated honestly: this covers the Linux and macOS legs only. Buildkite
-# hosted agents are Linux and macOS; there is no hosted Windows. `Test
-# (windows-latest)` in .github/workflows/ci.yml runs the installer PATH helper
-# and an NSIS installer regression on a product that ships a Windows installer,
-# so that leg must stay on GitHub Actions until a Windows agent exists. Do not
-# read a green build here as full platform coverage.
-#
-# This pipeline is advisory until its checks are proven green on real pull
-# requests. The required checks in the `protect-main` ruleset are still the
-# GitHub Actions contexts; moving them is a separate, deliberate change.

 # line comments, anchored to the PR head SHA. CODEOWNERS (@Hmbown) stays the
 # human owner — this review posts alongside it and never approves.
 #
-# Setup — full step-by-step guide in docs/GITHUB_APP.md. Summary:
-#   1. Key: Settings -> Secrets and variables -> Actions -> New repository
-#      secret `CODEWHALE_API_KEY`. This is the canonical name: it is your
-#      Codewhale account's review key, not any one vendor's. The workflow maps
-#      it into whatever env var the configured provider expects.
-#      BYOK alternative: set the provider's own key instead
-#      (`ZAI_API_KEY`, `DEEPSEEK_API_KEY`, `OPENROUTER_API_KEY`,
-#      `ANTHROPIC_API_KEY`); any one of them is enough.
-#   2. Which agent runs the review: repository variables
-#      `CODEWHALE_REVIEW_PROVIDER` (e.g. `zai`) and `CODEWHALE_REVIEW_MODEL`
-#      (e.g. `GLM-5.3`). Both optional — see "Route selection" below.
-#   3. Optional identity: to post as the Codewhale Agent GitHub App instead
-#      of the workflow's github-token identity, set repository variable
-#      `CODEWHALE_APP_ID` and secret `CODEWHALE_APP_PRIVATE_KEY`; the job
-#      mints an installation token via actions/create-github-app-token.
-#   4. Optional output budget: repository variable
-#      `CODEWHALE_REVIEW_MAX_OUTPUT_TOKENS` — see "Output budget" below.
-# Until at least one accepted key exists the job no-ops with a notice (stays
-# green), so this workflow is safe to merge before it is configured.
+# Setup: docs/GITHUB_APP.md. CODEWHALE_API_KEY is an account machine key;
+# it stays on the Codewhale relay and is never copied into a vendor variable.
+# Account mode requires an explicit account-catalog provider/model id in
+# CODEWHALE_REVIEW_MODEL. BYOK uses the provider's own key unchanged.
 #
-# Actions-syntax note (why the `env:` hoist below exists):
-#   the `secrets` context is NOT available in a job-level `if:`. It IS
-#   available in a job-level `env:`, and step-level `if:` can read the `env`
-#   context. So the key-presence test is evaluated once into
-#   `env.HAS_ANY_KEY` at job scope and every step gates on that string.
-#   Only non-secret booleans live at job scope; the key values themselves are
-#   injected into the single step that needs them.
+# Only same-repository PRs receive model/App secrets or execute the candidate
+# build. Fork PRs fetch objects against a trusted base checkout, but do not run
+# a model review. Keep this pull_request event: a PR must not gain secrets by
+# being fetched for its diff. Same-repository authors already have write access.
 #
-# Route selection:
-#   `CODEWHALE_REVIEW_PROVIDER` is passed straight through as
-#   `codewhale review --provider <name>`, which pins the route. Without it a
-#   model offered by more than one configured route hard-errors
-#   ("available from configured provider route(s): openrouter, zai"). When
-#   the variable is unset the provider is inferred from which key is present.
-#
-# Output budget:
-#   GLM-5.3 is a reasoning model: it emits `reasoning_content` before
-#   `content`, and both are charged against `max_tokens`. A small cap
-#   therefore yields an EMPTY review rather than an error. The CLI's
-#   automatic cap (64K) is already generous, so this workflow sets no cap by
-#   default; `CODEWHALE_REVIEW_MAX_OUTPUT_TOKENS` can override it but is
-#   rejected below a floor that leaves no room for the answer. The run step
-#   also fails loudly on a zero-length review instead of reporting success.
+# CODEWHALE_REVIEW_MAX_CHARS bounds each complete ordered review pass
+# (default 200000). CODEWHALE_REVIEW_MAX_PASSES defaults to 1; increasing it is
+# an explicit spend/duration choice. Exceeding either bound never posts a prefix.
+# Missing keys and provider outages keep the existing advisory policy, and
+# their explicit non-run receipts must never be counted as completed reviews.

-
-# Website install step — independent Assessment A
-
-Scope: only the changed install step in `web/lib/content/getting-started.ts`, rendered by `web/components/getting-started-steps.tsx`. Read the workspace, repository, and `web/AGENTS.md` guidance. No context script, detector, installation, or external request was run. No detector findings were seen. No source files were edited.
-
-## Verdict
-
-The copy achieves the intended hierarchy: published GitHub release on macOS/Linux first; `codewhale update` for later releases; npm/Cargo available through the full guide; local development builds explicitly separate. English and Chinese convey the same four facts. No critical copy defect found. This is a successful narrow correction, not an assessment of the complete guide or website.
-
-The wording is concrete and restrained. It belongs to a technical product and does not need a broader visual redesign. The shared content source preserves consistency between its consumers and avoids a page-specific localization fork.
-
-## Actual observations
-
-- Opened the built `/en/docs/guide` and `/zh/docs/guide` in a fresh native CUA Chrome Guest tab. Both displayed the changed paragraph, installer command, `codewhale doctor`, and descriptive localized Full install guide link.
-- The complete installer command is present in the accessibility text in both locales.
-- In the inspected desktop layout, the new long command extends beyond the narrow first-column code box and requires horizontal scrolling. The visible first line stops partway through the URL; the full release-installer destination and pipe are not visible together. This is contained code-block overflow, not established page-level overflow or lost text.
-- Source inspection confirms `<pre><code>` semantics, `overflow-x: auto` and `white-space: pre`. The renderer offers no copy control. Full keyboard scrolling, text selection, screen-reader announcements, and contrast were not tested.
-- Local installer source selects GitHub release assets and handles Darwin/Linux; local docs show this same installer and the later updater. These are source receipts, not proof of current public downloads or successful installation.
-
-## Priority issue
-
-**P2 — The longer primary install command is awkward to inspect and copy at the rendered desktop width.** The new default command makes the existing horizontal-scroll presentation more consequential: a first-time reader cannot see the complete command in one glance. Make a narrowly scoped improvement for this install command: permit soft wrapping without changing its text, or reuse an existing accessible copy control. If keeping horizontal scrolling, verify keyboard reachability and full-command selection. Do not expand this into a redesign of the four-step grid or the untouched steps.
-
-No P0/P1 issue found within this copy slice. The release/update/alternative/local-build wording needs no additional prerequisite text or warning banner.
-
-## Applicable heuristic scores
-
-| Heuristic | Score | Scope-specific basis |
-|---|---:|---|
-| System status | n/a | Static instruction; no installation was performed. |
-| Match to real world | 4 | Clear platform, release provenance, later-update instruction. |
-| User control/freedom | n/a | No stateful operation in this slice. |
-| Consistency | 4 | Shared EN/ZH content, matching local installer/docs. |
-| Error prevention | 3 | Published release and local development build are distinguished. |
-| Recognition over recall | 2 | Complete command requires horizontal inspection. |
-| Flexibility/efficiency | 2 | Long command has no direct copy action; keyboard scrolling unverified. |
-| Aesthetic/minimalism | 3 | Short, focused paragraph; one primary route with alternatives deferred. |
-| Error recovery | n/a | Installer outcome/recovery is outside the reviewed copy. |
-| Help/documentation | 3 | Clear localized link to deeper installation guidance. |
-| **Total** | **21/28** | **Good; narrow command usability improvement remains.** |
-
-Cognitive load is low for the changed decision: one recommended installation path, one validation command, and one deeper-reading link. Alternatives are named without presenting competing command menus. The long command adds interaction effort rather than conceptual ambiguity.
-
-## Evidence limits
-
-The CUA browser provider was unavailable; native CUA Chrome supplied a fresh Guest tab. EN/ZH desktop screenshots were observed without changing viewport/window size; output image size was 768×930, exact CSS viewport unmeasured. The Guest tab was closed, then browser ownership was returned to Assessment B. No mobile inspection, homepage rendering, external GitHub/install URL validation, install/update execution, broad website audit, or test suite was performed by Assessment A. Untouched steps and full-guide content were not assessed.
-
-Questions skipped: the user already authorized implementation.
-
-## Independent responsive evidence
-
-B ran the narrow markup detector once: exit 0, zero findings. Native Chrome at 390px confirmed EN/ZH command-container overflow beyond the grid, and keyboard Tab reached the localized Full install guide link with a visible outline. Root independently measured the same intrinsic-width problem in CUA: a 343px grid allocated a 382.6px track, extending the command box beyond the viewport. This strengthens A’s scoped P2 without changing its provisional 21/28 score. No P0/P1 established. Both assessments were isolated, and A completed before B findings reached synthesis. No mutable overlay was available; native screenshots and read-only DOM geometry supplied the evidence. No installer or updater was executed.

-homepage detector scan returned zero findings. Native browser evidence
-covered English and Chinese home/product/guide at the available window size;

-Preserve the illustrated folio, real supplied TUI capture, strong serif

-Priority backlog processed:
-- P1: first-arrival consent focus and forced choice. Removed initial focus,

-- P2: dark illustration under hero text. Reserved a light paper field behind

-- P2: ambiguous Web client versus Web app labels. EN/ZH now explicitly label
-  the Local web client and distinguish hosted remote control.
-- P3: repeated ownership pitch and unscoped final installer. Shortened the

-## Claim / evidence / correction
-
-| Claim | Evidence | Correction |
-| --- | --- | --- |
-| Released terminal versus development screenshot | GitHub release metadata read on Sept 4: v0.9.11, published Aug 23. Local tag resolves `96d13a0bc3f40280ea3865280ad5ccf0e2845e6f`. Screenshot provenance identifies unreleased 0.9.12 without exact commit. | Retain release label and separate development screenshot caption. |
-| “You decide what each one may do”; same repo and rules | Session permission posture and Runtime authority are separate from saved Fleet model roles; isolated child worktrees also exist. | Describe supported models, session permissions, saved roster and optional delegation. No universal shared-checkout or individual-authority UI promise. |
-| 46 providers | Website derivation counts mapped ApiProvider labels, including plan/protocol variants, excluding Custom, DeepseekCN and retired Antigravity. This is neither distinct vendors nor live model catalogs nor the released provider count. Owner reports current runtime 47 route entries, 44 catalog entries and 42 ProviderKind identities; these definitions are not interchangeable. | Remove numeric badge and models prose across all 18 homepage locales. Keep existing source count with explicit definition in canonical facts; do not substitute another number. |
-| Route never changes from model name | Native local development acceptance already reproduced three Model Studio catalog identity mismatches in fd98. Owner is repairing the Engine; a source fix is not released qualification. | Remove absolute EN/ZH guarantees; ask users to inspect selected provider/model/endpoint. Do not equate catalog identity failure with proven inference misrouting. |
-| Local servers need no key | Authentication depends on server configuration. | Say local servers may require authentication. |
-| Plan is read-only; nothing is written | v0.9.11 `docs/MODES.md` and Engine tool catalog describe central file-mutation/shell refusal, policy-allowed research and separately persisted session settings/state. | Name file/shell boundary and possible external research; remove blanket no-write claim from Product. |
-| `/fleet setup` exact four-step wizard | v0.9.11 `crates/tui/src/tui/views/fleet_setup.rs` resolves `SelectedFleet` or `LegacyProfiles`. Selected named Fleet opens its editor. Legacy path chooses role/model, with optional thinking on review. | Keep command, make step optional and accurately describe both destinations. Shared homepage/guide and EN/ZH Fleet docs updated. No published binary interaction claimed. |
-| Install/auth commands | v0.9.11 source contains auth set provider handling and Fleet setup; GitHub assets include terminal Linux/macOS/Windows archives. | Keep commands and released terminal target statement. No fresh install, key write or provider call performed. |
-| Public web sign-in and same-session remote control available | Source routes and local fixtures exist. This audit has no deployed authenticated same-session task acceptance. | EN/ZH homepage/Product say development preview and explicitly unverified public remote control. |
-| Desktop alpha builds exist on three platforms | Local macOS Dogfood startup has a receipt; Linux/Windows downloadable Tauri artifacts are not established. Windows terminal installer is not Tauri desktop proof. | Describe tested local macOS development build and no released desktop app download. |
-| Nothing on this site can charge you | An absolute statement exceeds evidence and obscures provider billing. | State terminal needs no Codewhale account; provider usage belongs to the user's provider account; account creation does not purchase model access. |
-| Ask/Auto-Review/Full Access absolutes | Approval rules, saved posture and hard policy boundaries affect actual execution. | Product describes rule-based prompts/review and persistent hard boundaries; removes universal every-write and never-default claims. |
-
-## Evidence boundaries
-
-Read-only release metadata and asset inventory:
-`/tmp/cwa-app-parity-20260904/site-release-claims-v0911.json`.
-No release artifact was downloaded or executed during this slice. Git tag source
-is source evidence, not a fresh installed task acceptance. No authenticated
-public web flow, provider request, deployment, billing action or customer task
-was performed. Source/provider integration remains independently qualified by
-its owner.
-
-Numeric models prose is corrected in all homepage languages. Broader hero,
-availability and linked documentation claims outside EN/ZH remain unaudited in
-this slice and must not be treated as reviewed translations. The English and
-Chinese scope is deliberate; a passing locale shape check does not establish
-translation accuracy or truth across the rest of the site.
-
-## Verification
-
-Initial tests: 405 passed, 2 failed (old keyless-launch phrasing assertion and
-models-body placeholder parity). The old assertion now checks the narrower
-behavior; every homepage models paragraph no longer uses the ambiguous count.
-Final tests: 407 passed across 47 files, 0 failed.
-Further build/browser/critique receipts are recorded below when complete.
-
-Final validation: facts, 23-topic docs, locale/catalog checks passed; lint 0 errors and 2 pre-existing logo-image warnings; webpack production build generated785 pages. Parent inspected EN desktop and saved `/tmp/cwa-app-parity-20260904/screenshots/site-claims-en-desktop.png`.
-
-Isolated Impeccable A:25/32 applicable, specificity3/4. B ran the actual detector:0 findings; inspected EN desktop and390 screenshot. A had mobile screenshot timeouts and collected EN/ZH DOM evidence only; B did not complete Chinese browser verification. No complete bilingual visual QA claim. Reports: `/tmp/cwa-app-parity-20260904/site-claims-design.md` and `site-claims-detector.md`.
-
-Two bounded P2 refinements remain for the founder's newly requested hero-scale slice: mark the Fleet heading visibly optional and verify/fix the narrow install Copy control's out-of-bounds geometry. The copy audit is committed separately to release canonical facts ownership; this is not a declaration that the full homepage is polished. The newly requested replacement terminal capture and default-on/opt-out analytics policy are separate in-progress changes, not included in this commit.

+- Cancelling a foreground shell wait stops its owned process group even when

+- Saved Fleet model identifiers retain exact spelling through selection,

+- Chat wrapping reserves its scrollbar gutter consistently, keeping long
+  identifiers readable when the viewport changes.
+- The Engine keeps large send-message futures off the event loop's stack,
+  preventing stack exhaustion when a restored session starts a provider turn.
+- New, imported, and live session titles skip runtime handoffs and use the
+  first real user prompt. Explicitly renamed titles retain priority
+  (#6012, thanks @SparkofSpike).
+- UI dispatch acceptance now precedes Engine execution, so a delayed acceptance
+  callback cannot overwrite a turn that has already started or completed.
+  Cancelling before acceptance preserves the prompt and leaves the next
+  dispatch usable.
+- Bottom-chrome effort is omitted when the route cannot prove an effective
+  tier; `/status` retains the full explanation. Cost remains visible when
+  known, and `cost: unknown` remains on metered routes lacking a reading (#5950).

+- Signed cloud model facts can refresh provider capabilities and prices while

+- Saved sessions preserve exact provider routes. Auxiliary model calls settle

+  including recovery, rather than resolving a new price at completion
+  (#5726, #5848).
+- `[tui].posture_bar` and `[tui].metrics_line` accept `full`, `compact`, or

 ## Project Structure
 
-codewhale is a Cargo workspace. The live runtime and the majority of TUI,
-engine, and tool code currently live in `crates/tui/src/`. Smaller workspace
-crates provide shared abstractions that are being extracted incrementally.

+Codewhale is a Cargo workspace with one Engine implementation in
+`crates/tui/src/core/engine/`. The public `codewhale` executable links the
+TUI/runtime library; interactive sessions, noninteractive runs and the Runtime
+API share that Engine.
+
+| Path | Purpose |
+| --- | --- |
+| `crates/cli/` | Public command entrypoint, configuration commands and runtime dispatch |
+| `crates/tui/` | Interactive terminal, Engine, tools, Runtime API and embedded local web client |
+| `crates/core/`, `crates/protocol/`, `crates/state/` | Request construction, session/turn types, protocol framing and persistence |
+| Other `crates/` | Shared configuration, credentials, telemetry, hooks, workflow and packaging support; see each Cargo manifest |
+| `web/` | Public Next.js website and documentation; separate from the embedded Runtime web client |
+| `telemetry-ingest/` | Telemetry service, schemas and service tests |
+| `extensions/`, `integrations/` | Editor integration and external-service bridges |
+| `npm/`, `packaging/`, `nix/` | npm wrappers/SDK and platform installation definitions |
+| `computer/snapshots/` | Cloud Computer image definitions, pinned independently of the source checkout |
+| `deploy/` | Deployment templates consumed by setup scripts, including Tencent Lighthouse services |
+| `fleets/`, `workflows/` | Distributed Fleet definitions and workflow examples |
+| `brand/` | Source artwork and generated brand variants used by the README, website and terminal |
+| `docs/` | User/developer documentation, schemas, fixtures and referenced release material |
+| `scripts/`, `.github/`, `.cnb.yml` | Development, validation, CI and release tooling |
+| `patches/` | Vendored dependency fixes, including their licensing files |
+
+Generated files that the product embeds or validates, such as model catalogs,
+website facts and schemas, remain tracked with their generators. Platform
+mirrors such as `.winget/` are retained when their packaging tools require them.
+Keep local critique output, temporary verification reports and personal
+operator instructions outside the tracked product tree; describe the change
+and its validation in the pull request. Do not copy workspace-level operator
+`AGENTS.md` or `CLAUDE.md` files into this repository.
+
+See [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md) for the runtime data flow and
+[the build guide](docs/BUILD_PERFORMANCE.md) for crate dependencies and local
+verification.

-- **استخدم النموذج الذي تريده.** اتصل بموفّرين مستضافين أو بنماذج محلية عبر Ollama أو vLLM أو SGLang. بدّل الموفّر والنموذج باستخدام `/model`.
-- **ابقَ مسيطرًا.** وضع Plan للقراءة فقط. تجعل أوضاع Ask وAuto-Review وFull Access سلوك الموافقة واضحًا. يتراجع `/undo` عن الجولة الأخيرة، ويعيد `/restore` مساحة العمل إلى لقطة سابقة.
+- **اختر نماذجك.** اتصل بموفّرين مستضافين أو بنماذج محلية عبر Ollama أو vLLM أو SGLang. استخدم `/provider` لتغيير الموفّر و`/model` لاختيار نموذج.
+- **ابقَ مسيطرًا.** افحص الإجراءات المقترحة والتغييرات الناتجة في الملفات. تحدد إعدادات الموافقة متى تلزم المراجعة؛ ويظل Full Access ملتزمًا بالحدود الصارمة للسياسات. يساعدك `/undo` و`/restore` على استعادة مساحة العمل بعد التغييرات.
 - **حافظ على تنظيم الأعمال الطويلة.** احفظ الجلسات، وحدد `/goal` دائمًا، وراجع مسارات العمل قبل تشغيلها، ونسّق بين الوكلاء من دون تحويل تعليماتهم الداخلية إلى جزء من محادثتك.
 - **وسّع الوكيل الذي لديك بالفعل.** صِل خوادم MCP والمهارات، واضبط الخطافات، واحتفظ بأدوار الوكلاء كملفات مقروءة في مشروعك أو إعداداتك الشخصية.

-- **Mantén el control.** Plan és només de lectura. Ask, Auto-Review i Full Access fan visible el comportament de les aprovacions. `/undo` desfà l’últim torn i `/restore` retorna l’espai de treball a una instantània anterior.

 - **Mantén organitzades les feines llargues.** Desa sessions, defineix un `/goal` durador, revisa els fluxos de treball abans que s’executin i coordina agents sense convertir les seves instruccions internes en part de la teva conversa.
 - **Amplia l’agent que ja tens.** Connecta servidors MCP i habilitats, configura hooks i conserva els rols d’agent com a fitxers llegibles al projecte o a la configuració personal.

 ## Por qué Codewhale
 
-- **Usa el modelo que prefieras.** Conecta proveedores alojados o modelos locales mediante Ollama, vLLM o SGLang. Cambia de proveedor y modelo con `/model`.
-- **Mantén el control.** Plan es de solo lectura. Ask, Auto-Review y Full Access hacen visible el comportamiento de las aprobaciones. `/undo` revierte el último turno y `/restore` devuelve el espacio de trabajo a una instantánea anterior.
+- **Elige tus modelos.** Conecta proveedores alojados o modelos locales mediante Ollama, vLLM o SGLang. Usa `/provider` para cambiar de proveedor y `/model` para elegir un modelo.
+- **Mantén el control.** Revisa las acciones propuestas y los cambios que producen en los archivos. La configuración de aprobaciones determina cuándo se necesita una revisión; Full Access sigue respetando los límites obligatorios de las políticas. `/undo` y `/restore` ayudan a recuperar cambios del espacio de trabajo.
 - **Mantén organizado el trabajo de larga duración.** Guarda sesiones, establece un `/goal` duradero, revisa los flujos de trabajo antes de ejecutarlos y coordina agentes sin convertir sus instrucciones internas en parte de tu conversación.
 - **Amplía el agente que ya tienes.** Conecta servidores MCP y habilidades, configura hooks y conserva los roles de los agentes como archivos legibles en tu proyecto o configuración personal.

 ## Codewhale क्यों
 
-- **अपनी पसंद का मॉडल इस्तेमाल करें।** होस्ट किए गए प्रोवाइडर या Ollama, vLLM अथवा SGLang के माध्यम से लोकल मॉडल जोड़ें। `/model` से प्रोवाइडर और मॉडल बदलें।
-- **नियंत्रण अपने पास रखें।** Plan केवल पढ़ने के लिए है। Ask, Auto-Review और Full Access अनुमोदन के व्यवहार को स्पष्ट बनाते हैं। `/undo` पिछला टर्न वापस करता है और `/restore` वर्कस्पेस को पहले के स्नैपशॉट पर लौटाता है।
+- **अपने मॉडल चुनें।** होस्ट किए गए प्रोवाइडर या Ollama, vLLM अथवा SGLang के माध्यम से लोकल मॉडल जोड़ें। प्रोवाइडर बदलने के लिए `/provider` और मॉडल चुनने के लिए `/model` इस्तेमाल करें।
+- **नियंत्रण अपने पास रखें।** प्रस्तावित कार्रवाइयों और उनसे फ़ाइलों में हुए बदलावों की जाँच करें। अनुमोदन की सेटिंग तय करती हैं कि समीक्षा कब ज़रूरी है; Full Access भी नीति की बाध्यकारी सीमाओं का पालन करता है। `/undo` और `/restore` बदलावों के बाद वर्कस्पेस बहाल करने में मदद करते हैं।
 - **लंबे काम को व्यवस्थित रखें।** सेशन सहेजें, स्थायी `/goal` तय करें, वर्कफ़्लो चलने से पहले उनकी समीक्षा करें और एजेंटों के आंतरिक निर्देशों को अपनी बातचीत में जोड़े बिना उनका समन्वय करें।
 - **अपने मौजूदा एजेंट को विस्तृत करें।** MCP सर्वर और स्किल जोड़ें, हुक कॉन्फ़िगर करें और एजेंट की भूमिकाओं को अपने प्रोजेक्ट या निजी सेटिंग में पढ़ने योग्य फ़ाइलों के रूप में रखें।

-Codewhale adalah agen pemrograman sumber terbuka untuk terminal Anda, dibuat dengan Rust dan dikembangkan secara terbuka bersama orang-orang yang menggunakannya.
+Codewhale adalah agen sumber terbuka yang membaca proyek, mengedit berkas, menjalankan perintah, dan memeriksa hasil kerjanya dengan model yang dihosting atau model lokal pilihan Anda. Mulailah dengan satu tugas di terminal. Untuk pekerjaan yang lebih besar, bagikan sebagian pekerjaan kepada agen dengan model dan peran yang berbeda.

+## Terminal, aplikasi, dan Computer Use
+
+Terminal dan klien grafis terhubung ke Codewhale Runtime, yang menjalankan agen beserta alatnya:
+
+- **Terminal:** `codewhale` membuka antarmuka interaktif; `codewhale exec` menjalankan tugas dari skrip atau job CI.
+- **Browser lokal:** `codewhale web` membuka [klien web lokal](docs/WEB.md) bawaan untuk Runtime yang sama.
+- **Aplikasi web dan desktop Codewhale:** lingkungan kerja grafis yang sedang dikembangkan. Ketersediaannya tercantum di [halaman produk](https://codewhale.net/en/product).
 
-## GUI frontend
+**Computer Use menambahkan alat untuk mengamati dan berinteraksi dengan aplikasi lain.** Plugin ini disertakan dalam kode sumber saat ini. Tinjau akses yang diminta dan aktifkan plugin sebelum digunakan; izin OS dan persyaratan platform tetap berlaku. Lihat [panduan Computer Use](crates/tui/plugins/computer-use/README.md) yang disertakan dan [pengaturan plugin](docs/PLUGINS.md).

 ## Mengapa Codewhale
 
-- **Gunakan model yang Anda inginkan.** Hubungkan penyedia terkelola atau model lokal melalui Ollama, vLLM, atau SGLang. Ganti penyedia dan model dengan `/model`.
-- **Tetap memegang kendali.** Plan hanya dapat membaca. Ask, Auto-Review, dan Full Access menampilkan perilaku persetujuan dengan jelas. `/undo` membatalkan giliran terakhir dan `/restore` mengembalikan ruang kerja ke snapshot sebelumnya.
+- **Pilih model Anda.** Hubungkan penyedia terkelola atau model lokal melalui Ollama, vLLM, atau SGLang. Gunakan `/provider` untuk mengganti penyedia dan `/model` untuk memilih model.
+- **Tetap memegang kendali.** Periksa tindakan yang diusulkan dan perubahan berkas yang dihasilkannya. Pengaturan persetujuan menentukan kapan peninjauan diperlukan; Full Access tetap mematuhi batas kebijakan yang wajib dipenuhi. `/undo` dan `/restore` membantu memulihkan perubahan ruang kerja.
 - **Jaga agar pekerjaan panjang tetap teratur.** Simpan sesi, tetapkan `/goal` yang bertahan lama, tinjau alur kerja sebelum dijalankan, dan koordinasikan agen tanpa memasukkan instruksi internal mereka ke transkrip Anda.
 - **Perluas agen yang sudah Anda miliki.** Hubungkan server MCP dan keterampilan, konfigurasikan hook, dan simpan peran agen sebagai berkas yang mudah dibaca di proyek atau pengaturan pribadi Anda.

+- **Browser locale:** `codewhale web` apre il [client web locale](docs/WEB.md) incluso, che usa lo stesso runtime.
+- **App web e desktop di Codewhale:** ambienti di lavoro grafici in fase di sviluppo. La loro disponibilità è indicata nella [pagina del prodotto](https://codewhale.net/en/product).
 
-## Interfaccia grafica
+**Computer Use aggiunge strumenti per osservare altre applicazioni e interagire con esse.** Il plugin è incluso nel codice sorgente attuale.

 ## Perché Codewhale
 
-- **Usa il modello che preferisci.** Collega provider gestiti oppure modelli locali tramite Ollama, vLLM o SGLang. Cambia provider e modello con `/model`.
-- **Mantieni il controllo.** Plan è in sola lettura. Ask, Auto-Review e Full Access rendono visibile il comportamento delle approvazioni. `/undo` annulla l’ultimo turno e `/restore` riporta l’area di lavoro a uno snapshot precedente.
+- **Scegli i tuoi modelli.** Collega provider gestiti oppure modelli locali tramite Ollama, vLLM o SGLang. Usa `/provider` per cambiare provider e `/model` per scegliere un modello.
+- **Mantieni il controllo.** Controlla le azioni proposte e le modifiche ai file che ne derivano. Le impostazioni di approvazione determinano quando è necessaria una revisione; Full Access continua a rispettare i limiti vincolanti delle regole. `/undo` e `/restore` aiutano a recuperare le modifiche dell’area di lavoro.
 - **Mantieni organizzati i lavori lunghi.** Salva le sessioni, imposta un `/goal` duraturo, rivedi i workflow prima dell’esecuzione e coordina gli agenti senza trasformare le loro istruzioni interne in parte della tua conversazione.
 - **Estendi l’agente che hai già.** Collega server MCP e skill, configura gli hook e conserva i ruoli degli agenti come file leggibili nel progetto o nelle impostazioni personali.

+  Approval settings govern when review is needed; Full Access still respects
+  hard policy boundaries. `/undo` and `/restore` help recover workspace changes.

-- **Zachowaj kontrolę.** Tryb Plan jest tylko do odczytu. Ask, Auto-Review i Full Access jasno pokazują sposób zatwierdzania działań. `/undo` cofa ostatnią turę, a `/restore` przywraca przestrzeń roboczą do wcześniejszej migawki.
+- **Wybieraj modele.** Połącz się z hostowanymi dostawcami lub lokalnymi modelami przez Ollama, vLLM albo SGLang. Polecenie `/provider` służy do zmiany dostawcy, a `/model` do wyboru modelu.

Ustawienia zatwierdzania określają, kiedy potrzebna jest weryfikacja; Full Access nadal przestrzega nieprzekraczalnych ograniczeń zasad. `/undo` i `/restore` pomagają przywrócić przestrzeń roboczą po zmianach.
 - **Utrzymuj porządek w długich zadaniach.** Zapisuj sesje, ustawiaj trwały `/goal`, sprawdzaj przepływy pracy przed uruchomieniem i koordynuj agentów bez umieszczania ich wewnętrznych instrukcji w zapisie Twojej rozmowy.
 - **Rozszerzaj agenta, którego już masz.** Podłączaj serwery MCP i umiejętności, konfiguruj hooki oraz przechowuj role agentów jako czytelne pliki w projekcie lub ustawieniach osobistych.

+## Terminal, aplicativos e Computer Use
+
+O terminal e os clientes gráficos se conectam ao Runtime do Codewhale, que executa o agente e suas ferramentas:
+
+- **Terminal:** `codewhale` abre a interface interativa; `codewhale exec` executa uma tarefa a partir de um script ou de um job de CI.
+- **Navegador local:** `codewhale web` abre o [cliente web local](docs/WEB.md) incluído, que usa o mesmo runtime.
+- **Aplicativos web e desktop do Codewhale:** ambientes de trabalho gráficos em desenvolvimento. A disponibilidade é informada na [página do produto](https://codewhale.net/en/product).
 
-## Interface gráfica
+**Computer Use adiciona ferramentas para observar outros aplicativos e interagir com eles.** O plugin está incluído no código-fonte atual. Revise o acesso solicitado e habilite-o antes de usar; as permissões do sistema operacional e os requisitos da plataforma continuam sendo necessários.

 ## Por que usar o Codewhale
 
-- **Use o modelo que quiser.** Conecte provedores hospedados ou modelos locais por meio do Ollama, vLLM ou SGLang. Alterne o provedor e o modelo com `/model`.
-- **Mantenha o controle.** O modo Plan é somente leitura. Ask, Auto-Review e Full Access tornam visível o comportamento das aprovações. `/undo` desfaz o último turno e `/restore` retorna o espaço de trabalho a um snapshot anterior.
+- **Escolha seus modelos.** Conecte provedores hospedados ou modelos locais por meio do Ollama, vLLM ou SGLang. Use `/provider` para trocar de provedor e `/model` para escolher um modelo.
+- **Mantenha o controle.** Revise as ações propostas e as alterações resultantes nos arquivos. As configurações de aprovação determinam quando uma revisão é necessária; Full Access continua respeitando os limites obrigatórios das políticas. `/undo` e `/restore` ajudam a recuperar alterações no espaço de trabalho.
 - **Mantenha trabalhos longos organizados.** Salve sessões, defina um `/goal` duradouro, revise os fluxos de trabalho antes da execução e coordene agentes sem transformar as instruções internas deles em parte da sua conversa.
 - **Amplie o agente que você já tem.** Conecte servidores MCP e habilidades, configure hooks e mantenha as funções dos agentes como arquivos legíveis no projeto ou nas suas configurações pessoais.

 ## Почему Codewhale
 
-- **Используйте нужную вам модель.** Подключайте облачных провайдеров или локальные модели через Ollama, vLLM или SGLang. Переключайте провайдера и модель командой `/model`.
-- **Сохраняйте контроль.** Режим Plan доступен только для чтения. Ask, Auto-Review и Full Access наглядно показывают порядок подтверждений. `/undo` отменяет последний ход, а `/restore` возвращает рабочую область к более раннему снимку.
+- **Выбирайте модели.** Подключайте облачных провайдеров или локальные модели через Ollama, vLLM или SGLang. Используйте `/provider` для смены провайдера, а `/model` — для выбора модели.
+- **Сохраняйте контроль.** Проверяйте предлагаемые действия и получившиеся изменения файлов. Настройки подтверждения определяют, когда нужна проверка; Full Access по-прежнему соблюдает жёсткие ограничения политик. `/undo` и `/restore` помогают восстановить рабочую область после изменений.
 - **Организуйте длительную работу.** Сохраняйте сеансы, задавайте постоянную `/goal`, проверяйте рабочие процессы перед запуском и координируйте агентов так, чтобы их внутренние инструкции не попадали в вашу переписку.
 - **Расширяйте уже настроенного агента.** Подключайте серверы MCP и навыки, настраивайте хуки и храните роли агентов в виде понятных файлов в проекте или личных настройках.

 ## Чому Codewhale
 
-- **Використовуйте потрібну вам модель.** Під’єднуйте хостингових провайдерів або локальні моделі через Ollama, vLLM чи SGLang. Змінюйте провайдера й модель за допомогою `/model`.
-- **Зберігайте контроль.** Режим Plan доступний лише для читання. Ask, Auto-Review і Full Access наочно показують поведінку погоджень. `/undo` скасовує останній хід, а `/restore` повертає робочий простір до попереднього знімка.
+- **Обирайте моделі.** Під’єднуйте хмарних провайдерів або локальні моделі через Ollama, vLLM чи SGLang. Використовуйте `/provider`, щоб змінити провайдера, і `/model`, щоб обрати модель.
+- **Зберігайте контроль.** Перевіряйте запропоновані дії та отримані зміни файлів. Налаштування погодження визначають, коли потрібна перевірка; Full Access і надалі дотримується жорстких обмежень політик. `/undo` та `/restore` допомагають відновити робочий простір після змін.
 - **Упорядковуйте тривалу роботу.** Зберігайте сеанси, установлюйте постійну `/goal`, перевіряйте робочі процеси перед запуском і координуйте агентів так, щоб їхні внутрішні інструкції не потрапляли до вашої розмови.
 - **Розширюйте вже наявного агента.** Під’єднуйте сервери MCP і навички, налаштовуйте хуки та зберігайте ролі агентів як зрозумілі файли у своєму проєкті або особистих налаштуваннях.

-- **Dùng mô hình bạn muốn.** Kết nối với nhà cung cấp được lưu trữ hoặc với mô hình cục bộ thông qua Ollama, vLLM hay SGLang. Chuyển nhà cung cấp và mô hình bằng `/model`.
-- **Luôn nắm quyền kiểm soát.** Plan chỉ cho phép đọc. Ask, Auto-Review và Full Access hiển thị rõ cách hoạt động của việc phê duyệt. `/undo` hoàn tác lượt gần nhất, còn `/restore` đưa không gian làm việc về một ảnh chụp trước đó.
+- **Chọn mô hình của bạn.** Kết nối với nhà cung cấp dịch vụ hoặc với mô hình cục bộ thông qua Ollama, vLLM hay SGLang. Dùng `/provider` để đổi nhà cung cấp và `/model` để chọn mô hình.
+- **Luôn nắm quyền kiểm soát.** Kiểm tra các thao tác được đề xuất và những thay đổi tệp do chúng tạo ra. Cài đặt phê duyệt quyết định khi nào cần xem xét; Full Access vẫn tuân thủ các giới hạn chính sách bắt buộc. `/undo` và `/restore` giúp khôi phục các thay đổi trong không gian làm việc.
 - **Sắp xếp công việc dài hạn.** Lưu phiên, đặt `/goal` lâu dài, xem lại quy trình trước khi chạy và phối hợp các tác nhân mà không đưa chỉ dẫn nội bộ của chúng vào bản ghi hội thoại của bạn.
 - **Mở rộng tác nhân bạn đang có.** Kết nối máy chủ MCP và kỹ năng, cấu hình hook, đồng thời lưu vai trò tác nhân dưới dạng các tệp dễ đọc trong dự án hoặc phần cài đặt cá nhân.

-The current product dispatcher wiring for this snapshot is absent.

-This directory is consequently an image definition and a bounded manual

+## Dispatcher wiring and acceptance limits
+
+The image definition lives only in this directory. The launcher in
+`crates/tui/src/cloud_dispatch.rs` selects `codewhale-cloud-agent` (or
+`CODEWHALE_DISPATCH_SNAPSHOT`), sends the account machine token in
+`CODEWHALE_API_KEY`, applies job labels, and uses the Daytona toolbox to clone
+and execute commands. `crates/tui/src/dispatch_runner.rs` drives that lifecycle.
+See the [dispatch guide](../../../docs/DAYTONA_CLOUD_DISPATCH.md) for the
+command surface.
+
+This describes source wiring. The image remains pinned to the Engine version
+listed above, and this repository does not establish a server-side
+account-token-to-provider-credential resolution path. A snapshot build or
+manual `codewhale exec` is evidence for that specific operation; it does not
+qualify account entitlement, provider credential custody, dispatcher execution,
+metering or customer use. The historical manual image receipt below is not
+acceptance of the current dispatcher.

+//! Cloud facts client: fetch `https://codewhale.net/api/facts/v1/<channel>`,
+//! verify the Ed25519 envelope against the keys pinned in
+//! `codewhale_config::cloud_facts::keys`, cache it under
+//! `$CODEWHALE_HOME/facts/cloud-facts.json`, and install the scoped view as the
+//! process-wide overlay. Modeled on the TUI's `models_dev_live` producer.
+//!
+//! Guarantees:
+//! - Never a startup dependency: [`maybe_load_persisted_cache`] is a bounded
+//!   synchronous disk read; all network happens in [`spawn_background_refresh`].
+//! - Off by default (`[cloud_facts].enabled = false`); `CODEWHALE_CLOUD_FACTS=1`
+//!   flips it, `CODEWHALE_DISABLE_CLOUD_FACTS=1` beats everything, CI markers
+//!   suppress the fetch.
+//! - The disk cache is re-verified on every load; untrusted bytes are cleared while the rollback floor is retained.
+//! - The fetch sends only a fixed user agent and `If-None-Match`; no
+//!   identifiers, cookies, or query parameters (PRD §5).
+//! - With no active pinned key the layer is inert even when enabled.

+//! Model-bound redaction opt-out (`[redaction] model_bound`).
+//!
+//! Codewhale masks credential-looking values in tool output before it is sent
+//! to an upstream model (the "model boundary"). That masking is a security
+//! backstop: a file read by a tool can contain a configured API key, a bare
+//! provider token, or a credential-shaped opaque string, and the model must
+//! never see those bytes.
+//!
+//! This module adds a deliberate, documented way to turn that masking off for
+//! users who must edit files that contain real credentials. Because it lowers
+//! a security boundary, it is not a plain boolean:
+//!
+//! * Setting `[redaction] model_bound = "disabled"` in `config.toml` only
+//!   records a *request*.
+//! * The request takes effect only after a restart of the interactive TUI and
+//!   an explicit confirmation on the startup gate screen, which persists a
+//!   receipt next to the config file actually loaded by that launch.
+//! * Non-interactive entry points (`codewhale exec`, hooks, automation) never
+//!   confirm anything; as long as no confirmation receipt exists they resolve
+//!   to the safe default (`Enabled`), whatever the config file says.
+//! * Dismissing the gate (choosing "keep masking on") leaves the config field
+//!   and the receipt untouched, so the next launch asks again until the user
+//!   confirms or edits the field back to `"enabled"`.
+//!
+//! A confirmation receipt is bound to the loaded config file, including an
+//! explicit `--config` or `CODEWHALE_CONFIG_PATH`. Different config filenames
+//! have independent receipts. A receipt is honored only while the canonical
+//! path, contents and modification time still match and the config requests
+//! `"disabled"`.
+//! Editing the field back to `"enabled"` - or changing `config.toml` in any
+//! way - and later re-requesting `"disabled"` always asks for a fresh
+//! confirmation, even when no process ran in between.

 ### Fixed
 
+- Cancelling a foreground shell wait stops its owned process group even when
+  the tool future is dropped. Explicitly backgrounded jobs retain their
+  ownership. Interrupted tool receipts distinguish work that started from
+  calls skipped before execution, and returned tool failures remain errors in
+  the next model request.
+- Saved Fleet model identifiers retain exact spelling through selection,
+  role pins, and roster changes, so changing one saved model does not modify
+  another identifier that differs only in letter case.
+- Chat wrapping reserves its scrollbar gutter consistently, keeping long
+  identifiers readable when the viewport changes.
+- The Engine keeps large send-message futures off the event loop's stack,
+  preventing stack exhaustion when a restored session starts a provider turn.
+- New, imported, and live session titles skip runtime handoffs and use the
+  first real user prompt. Explicitly renamed titles retain priority
+  (#6012, thanks @SparkofSpike).
+- UI dispatch acceptance now precedes Engine execution, so a delayed acceptance
+  callback cannot overwrite a turn that has already started or completed.
+  Cancelling before acceptance preserves the prompt and leaves the next
+  dispatch usable.
+- Bottom-chrome effort is omitted when the route cannot prove an effective
+  tier; `/status` retains the full explanation. Cost remains visible when
+  known, and `cost: unknown` remains on metered routes lacking a reading (#5950).

 ### Changed
 
+- The website uses Shannon Sans with versioned local font assets and retained
+  serif, monospace, and language fallbacks. Terminal fonts are unchanged.
+- `codewhale metrics` reports recorded model requests and stream recovery
+  separately from provider-reported token usage, with coverage for missing
+  and duplicate receipts. Status messages and cumulative snapshots do not
+  add requests or count tokens again.
+- Runtime turn receipts retain the Engine's terminal model-request, stream-retry,
+  and resume counters separately from displayed status and provider-reported
+  usage. These counters do not count HTTP retries inside a provider client or
+  establish provider billing.
+- Initial tool definitions no longer repeat shell interpreter guidance and
+  agent lifecycle/scope instructions in multiple description fields. Parameter
+  schemas, approval rules and dispatch behavior are preserved. This reduces
+  prompt schema size; it does not establish a provider billing regression.

+- Native plugin authoring guides now cover English and Chinese. The explicit
+  offline converter supports selected portable Skills and static Streamable
+  HTTP MCP declarations from OpenCode and DSH. Unsupported executable hooks,
+  automatic OAuth and policy-bearing configurations are refused; generated

+- Signed cloud model facts can refresh provider capabilities and prices while

+  recorded cost (#5752).
+- Saved sessions preserve exact provider routes. Auxiliary model calls settle
+  their usage once against the route and price snapshot that executed them,
+  including recovery, rather than resolving a new price at completion
+  (#5726, #5848).
+- `[tui].posture_bar` and `[tui].metrics_line` accept `full`, `compact`, or

+Use the Registry as the preferred source of specialized capabilities. Before
+using shell commands, custom code, or a throwaway script to solve a task, check

+of ready-made servers (filesystems, databases, browsers, media processing,

+
+## When to use
+
+- You are about to fetch data, reach a service, drive a tool, or automate a workflow.
+- The task needs a capability the current toolset lacks (a database, a
+  browser, a third-party API, …).
+- The task names a specialized operation or output (for example media

+- Skip only ordinary repo-native editing and simple shell/file operations that
+  do not need a specialized capability.
+
+## Workflow
+
+1. **Check the registry.** Call `registry_sync {}`. It returns the complete
+   catalog of eligible local stdio packages, including each server's name,
+   description, and required launch arguments. Packages declaring any
+   environment variable (including API keys/tokens) are excluded and never
+   written to the cache.
+2. **Match from context with a Registry-first bias.** Compare the user's full
+   task against every server name and description. A candidate is a match when
+   it plausibly covers the task's core specialized capability; wording does not
+   need to be exact. When such a candidate exists, you **must start it and inspect
+   its tools before** using `exec_shell`, local programs, custom code, or a manual
+   implementation. The availability or familiarity of a local alternative is
+   not a reason to skip the candidate. Skip Registry use only when every entry is
+   clearly irrelevant, or when a matching server fails to start after the retry
+   described below.
+3. **Install + run transactionally.** Call
+   `start_registry_mcp_server {registry_name: "<exact name>", arguments: {...}}`.
+   Supply only values listed in `required_args`; omit `arguments` when none
+   are required. Never install or launch the package through `exec_shell`.

+`start_registry_mcp_server` reports when a package exits before the handshake
+(often CLI help output = incomplete launch args). Verify the exact
+required arguments, retry once with the corrected structured values, and if
+it still fails move on to the next candidate. Failed starts are rolled back,
+so retrying the same Registry name is safe.

+The public MCP Registry ships hundreds of ready-made stdio servers

-The discovery and structured start tools are available in the active tool

 ## When to use
 
-- You are about to fetch data, reach a service, drive a tool, or automate a workflow.
-- The task needs a capability the current toolset lacks (a database, a
-  browser, a third-party API, …).
-- The task names a specialized operation or output (for example media

+- An available tool, a project script or test, or a few lines of local code
+  cannot do the job.
+- The task needs an external service, database, or protocol client that this
+  session has no access to.
+- You would otherwise install a package or reimplement a well-known converter
+  or client by hand.
+
+## When not to use
+
+- Ordinary work: writing and editing files, reading fixtures, running repo
+  commands, and checking your own output. Do those directly.
+- A capability an already-loaded tool covers, even partially — try it first.
+- A near-miss row in a result list. A scored match is a suggestion; the missing
+  capability is what decides.
 
 ## Workflow

-3. **Install + run transactionally.** Call
+1. **Name the gap.** State the capability you lack before searching. If you
+   cannot name one, you do not need the Registry.
+2. **Load and query.** `registry_sync` and `start_registry_mcp_server` are
+   deferred: load one with `tool_search` and use the returned schema. If a call
+   only loads the schema without executing, retry once with that schema. Then call
+   `registry_sync {query: "<the missing capability>"}`. It scores a host-side
+   snapshot and returns at most eight matches; the full index never enters the
+   conversation. Packages declaring any environment variable (including API
+   keys/tokens) are excluded and never written to the cache.
+3. **Judge the matches.** Take a server when it covers the gap you named. If
+   nothing does, refine the query once, then continue with local tools.
+4. **Install + run transactionally.** Call
    `start_registry_mcp_server {registry_name: "<exact name>", arguments: {...}}`.
-   Supply only values listed in `required_args`; omit `arguments` when none
-   are required. Never install or launch the package through `exec_shell`.
-4. **Solve the task with the new tools.** Their complete schemas are added
-   to the current turn immediately after a successful connection; call the
-   exact names returned by the start result.

-# computer-use
-
-Codewhale Computer Use — the `computer-use` plugin. One tool surface, four
-platforms, and **switching between registered computers as a default**: every
-tool accepts `computer`, and using a computer id sticks until you switch.
-
-The bundle is an Agent Plugins v1 package (`plugin.json` + sibling `mcp.json`,
-`commands/`, `skills/`): the Codewhale Engine discovers, reviews, installs, and
-runs it. Nothing here writes to your Codewhale configuration.
-
-| | |
-|---|---|
-| Platforms | macOS, Windows, Linux (X11 + Wayland), HarmonyOS (hdc devices) |
-| Hosts | macOS, Windows, Linux (`when.os`); HarmonyOS is a target device, not a host |
-| Transports | local process, ssh + bundled remote agent, hdc |
-| Runtime deps | none (Node ≥ 20; platform tools probed at call time) |
-| Tools | 38: observe, pointer, keyboard/text, semantic, clipboard, recording, computer registry |
-
-## Frontier ability set
-
-- **Observe & resolve** — `list_apps`, `list_windows`, `list_displays`,
-  `switch_display`, `get_app_state` (accessibility/UIA/uitest tree with
-  element indices + `state_id`), `screenshot` (display/region, raster-bound
-  coordinates), `zoom` (close-up crop of the last raster), `cursor_position`,
-  `open_application` (exact-name rule), `request_access` (fail-closed
-  permission/capability probe).
-- **Pointer** — left/double/triple/right/middle click, move, drag,
-  down/up, scroll (4 directions).
-- **Keyboard & text** — `type` (unicode), `key` (chords + repeat),
-  `hold_key`, `set_value` (semantic, background-safe), `select_text`,
-  `perform_action` (element's own actions: AXPress / UIA Invoke / AT-SPI / uitest).
-- **Recording** — `recording_start/stop/status/list` (see below).
-- **Computers** — `computer_list`, `computer_switch`, `computer_register`
-  (ssh agent auto-push), `computer_remove`.
-- **Safety** — `stop_computer_control` kill switch; permission probes that
-  name the missing grant; receipts on every call naming the computer it
-  happened on.
-
-## Requirements
-
-Tools and permissions are probed at call time; `request_access` reports what is
-missing and every capability **fails closed naming the missing tool or
-permission** — it never guesses and never half-acts.
-
-- **macOS** — Accessibility + Screen Recording permission for the terminal
-  app that hosts the Engine (System Settings → Privacy & Security).
-  python3+pyobjc or cliclick improves cursor reads. ffmpeg optional (mp4 remux).
-- **Windows** — PowerShell (built in); ffmpeg for recording.
-- **Linux** — X11: xdotool, wmctrl, scrot or imagemagick, xclip; Wayland:
-  grim, wtype, ydotool+ydotoold, wl-clipboard, wf-recorder; python3-pyatspi
-  for the accessibility tree; ffmpeg for recording on X11.
-- **HarmonyOS** — `hdc` on PATH with the device connected
-  (`hdc list targets`); ffmpeg on the host for snapshot-series recordings.
-
-## How the four platforms map
-
-| Ability | macOS | Windows | Linux | HarmonyOS |
-|---|---|---|---|---|
-| Accessibility tree | AX via System Events (JXA) | UIAutomation | AT-SPI (pyatspi) | `uitest dumpLayout` |
-| Raw input | CGEvent (JXA bridge) | user32 SendInput/mouse_event (PowerShell) | xdotool (X11) / ydotool+wtype (Wayland) | `uitest uiInput` |
-| Screenshots | `screencapture` | .NET CopyFromScreen | scrot/import (X11), grim (Wayland) | `snapshot_display` |
-| Recording | `screencapture -v` → .mov, ffmpeg remux to .mp4 | ffmpeg gdigrab | ffmpeg x11grab / wf-recorder | snapshot-series + ffmpeg mux |
-| Clipboard | pbcopy/pbpaste | Get/Set-Clipboard | xclip/xsel, wl-clipboard | fail-closed (not exposed by hdc) |
-
-## Remote computers (ssh)
-
-```json
-computer_register { "computer": "winbox", "transport": "ssh", "host": "winbox.lan", "user": "me" }
-```
-
-Registration pushes the self-contained agent (`agent.mjs` + `src/`) to
-`~/.codewhale-cu/agent/` on the remote over scp, probes the remote platform
-through it, and pins the result. Remote calls run
-`node agent.mjs <base64 json>` — one JSON receipt line back. Only an
-allow-listed tool set executes remotely; arguments travel as data, never as
-shell. Requires publickey ssh (BatchMode) and Node ≥ 20 on the remote.
-
-## HarmonyOS computers
-
-```json
-computer_register { "computer": "pad", "transport": "hdc" }
-```
-
-Drives the device over `hdc shell uitest ...` and `snapshot_display`. Element
-targets come from `dumpLayout`; input is touch-synthesis (click / swipe /
-inputText / keyEvent). Recording is honestly labeled `snapshot-series`
-(frame captures muxed on stop) because HarmonyOS exposes no CLI screen
-recorder.
+# Computer Use
+
+This is the Computer Use plugin included in Codewhale. The Engine embeds the
+runtime bundle, discovers it through the existing plugin registry, and runs
+only the copy the user has reviewed and enabled. Codewhale Apps uses that same
+Engine inventory and approval flow.
+
+The bundle provides 39 MCP tools for application and window observation,
+accessibility actions, screenshots and zoom, keyboard and pointer input,
+clipboard access, recording, and switching between registered computers.
+Implementation exists for macOS, Windows, Linux and HarmonyOS target devices;
+platform support still depends on the tools, OS grants and actual device
+verification described by the upstream project. A source build is not a
+published or certified release.
+Current launch qualification covers the local macOS candidate. Windows,
+Wayland, HarmonyOS and SSH require separate device and workflow evidence.
+
+## Included runtime
+
+macOS Codewhale builds carry the compiled native helper. Using the included
+plugin needs neither a separate Computer Use app nor a compiler. It uses the
+permission identity of its hosting Codewhale app or terminal. Accessibility
+and Screen Recording grants remain controlled by the user in System Settings.
+Use `request_access` to inspect readiness; a loaded plugin alone does not prove
+its OS permissions work.
+
+The MCP server requires Node.js 20 or newer. Codewhale Apps packages its own
+Node runtime; the CLI uses Node on PATH. Homebrew declares the dependency;
+Cargo and direct binary users can install Node from <https://nodejs.org/>.
+Linux also needs the appropriate X11 or Wayland utilities and AT-SPI bindings.
+Windows uses PowerShell and UI Automation. Linux and Windows recording is
+currently unavailable until recorder ownership and shutdown cleanup are built.
+HarmonyOS targets require a connected device and hdc.
+
+Persistent holds and drags on Linux and Windows currently require the separate
+session-aware Computer Use helper. Their direct bundled path refuses these
+operations before sending input. macOS carries its native input owner in the
+included bundle. Real Windows, Wayland and mixed-display validation is still
+required before claiming equivalent platform readiness.
+The current one-shot SSH agent also loses application binding between calls;
+stateful remote input needs a persistent session transport before it is ready.
+
+## Control and session ownership
+
+Select an application before sending input. On macOS, background selection
+(`activate:false`) supports process-directed typing and accessibility actions.
+It refuses gestures that would move the shared desktop pointer. Explicit
+foreground selection (`activate:true`) enables guarded shared-desktop input
+when the user has authorized exclusive desktop use. Neither mode is an isolated
+computer; cursor restoration does not make concurrent pointer control safe.
+Screenshots and zoom return actual image content to compatible vision models.
+Preview and recording are explicit opt-ins.
+Application observations return a concise default summary; request full detail
+when needed. Text-only models can use element roles, values and advertised
+actions. On macOS, optional local OCR enriches the selected window observation
+with text and raster bounds; it requires Screen Recording permission and does
+not invent accessibility elements or actions.
+The Engine permits one inline image up to 5 MiB per tool result; use a scoped
+capture or zoom when a larger image receives an omission receipt.
+
+Each task owns its MCP connection and computer selection, observations and
+held input. Subagents within that task share the task's Computer Use session.
+Stopping control or closing the task releases that session's input. Stale
+observations, unexpected foreground changes and unavailable capabilities fail
+closed with a receipt; successful dispatch still needs application-state
+verification.
 
 ## Development
 
-The bundle lives at `crates/tui/plugins/computer-use` in the Codewhale repository and has
-no dependencies to install; run its suites from that directory.
-
-```bash
-npm test          # unit + protocol tests (no GUI input performed)
-npm run smoke     # live end-to-end against this machine (isolated state dirs,
-                  # no clicks/typing into your session, no clipboard access)
-```
+The exact upstream source revision is recorded beside this directory in
+`computer-use.upstream-sha`. This tree contains the runtime and its tests;
+standalone app installers and release tooling belong to the upstream project.
 
-Smoke receipts land in `receipts/` with per-check pass/fail and artifact
-paths. Proven levels are separated: local live (this Mac: darwin) > mocked
-transport (ssh protocol, harmony backend logic) > code-complete (win32/linux
-paths, implemented to their documented tool interfaces but only verifiable on
-those platforms).
+Run `npm test` here for unit and protocol coverage. Those tests do not type or
+click in the user's applications. `npm run smoke` is a separate legacy live
+check: it captures and records the selected display, so run it only when that
+capture is intended. The upstream parity suite contains scoped application
+fixtures for interactive verification.

-//! Offline model metadata catalog (#3072).

 //! This module adds a secret-free metadata layer in front of the legacy model
 //! tables. It is intentionally conservative: startup reads a local cache plus a
 //! bundled snapshot, never performs a network refresh, and only overrides a
 //! legacy fact when the active catalog entry actually carries that field.
+//! The unscoped `catalog/openrouter.json` file cannot safely own a live provider
+//! roster; new provider/base-URL-scoped refreshes and runtime consumers use
+//! `provider_catalog_live` + `provider_lake`. Keep this reader only until the
+//! remaining `models`, `pricing`, and safe-label compatibility callers migrate.

+//! Durable, secret-free per-provider `/models` catalog cache.
+//!
+//! This is the persistence owner for [`codewhale_config::catalog::ProviderCatalogCache`].
+//! It replaces the process-only client refresh and provider_lake CLI cache writers: successful
+//! refreshes replace one exact `(provider kind, identity, base URL fingerprint)`
+//! partition, failures retain that partition's prior rows, and startup loads
+//! only the active route's exact partition. Credentials authorize the fetch in
+//! `client`; they never enter this module or its disk envelope. Baseten and
+//! Codewhale account rosters are memory-only and cleared before each refresh;
+//! a named custom route at either official endpoint follows the same rule.
+//!
+//! This deliberately does not import the legacy `model_catalog` cache at
+//! `catalog/openrouter.json`: that file has no provider/base-URL scope, so
+//! treating it as a provider-owned roster could leak stale facts across custom
+//! endpoints. `model_catalog` remains a read-only compatibility fallback for
+//! older model-metadata consumers while provider-lake/runtime consumers migrate;
+//! `catalog/provider-catalogs.json` is the sole writer-owned live roster store.
+//! Older per-endpoint `provider-*.json` files also lack the built-in/custom
+//! kind boundary and account-roster exclusion, so they are left untouched and
+//! replaced only by a newly authenticated refresh into this store.

-//! ShannonNet sandbox backend.
-//!
-//! Routes shell execution to a ShannonNet worker: a signed `cap://sandbox/exec`
-//! invocation inside a Task World owned by this installation's durable
-//! `codewhale` Agent. The worker may run on another tailnet node; Codewhale
-//! addresses the capability name, never a host, and every command leaves a
-//! signed receipt readable with `shannon trace`.
-//!
-//! The protocol is spoken by the `shannon` CLI (`--json`) rather than
-//! reimplemented here, so there is exactly one signer and one verifier. This
-//! module replaces the `integrations/codewhale/shannon_adapter.rs` sketch in
-//! the ShannonNet repository. It owns no model loop: the Engine stays the one
-//! turn loop and this backend is one `exec` at a time.
-//!
-//! Session lifecycle: [`ShannonBackend::new`] runs at backend creation (session
-//! start), resolves or creates the `codewhale` Agent, creates a Task World
-//! named after the workspace, and attaches the sandbox capability. Each
-//! `exec` is one signed invocation in that World.
-//!
-//! Sub-agents: [`SandboxBackend::for_child`] maps Codewhale's `agent` tool to
-//! Shannon `spawn` — a child identity certified by this Agent, with a World
-//! projected from the session World (only `cap://sandbox/exec`, with the
-//! delegation depth attenuated) — and [`SandboxBackend::child_joined`] to
-//! `join`: a typed receipt on the task and the child's World destroyed.
-//! The child ships and runs in its own session container.
-//!
-//! [`SandboxBackend::child_context`] imports the session's memory hits into
-//! the `codewhale` Agent's memory graph (with provenance, idempotently) and
-//! compiles the bounded context the child's World may see — confidential
-//! notes never cross into it — as a text block for the child's prompt.
-//!
-//! Session end: dropping the session backend closes the World (a
-//! content-addressed checkpoint, then destroy) and the worker's session
-//! container, detached. A pointer file under the Codewhale home lets
-//! `/shannon` inspect the live session.
-//!
-//! Workspace sync: with `sync` on (the default), the backend ships the
-//! session's working tree into the worker's per-World session container
-//! before each command — a full archive first, then only what changed
-//! (added/modified files, deletions) — so remote builds and tests see the
-//! files the Engine just edited locally, not the worker's own checkout.
-//! Ignored files (`.gitignore`, `.git`) never leave the machine. The worker
-//! enforces path safety and size budgets on its side.

+//! decision, so the interactive TUI shows this full-screen gate on the next
+//! launch and only applies the opt-out after the user confirms it here (see
+//! [`codewhale_config::redaction`] for the effective-mode contract).

+//! The gate follows the onboarding visual grammar — one Underwater surface,

+//! users see it, and answering it never touches the `.onboarded` marker. The
+//! three actions mirror the workspace-trust screen's explicit-key discipline:

-//! This is terminal-bell-level only: every cue is one or two BEL (`\x07`)
-//! bytes written to stdout, exactly the bytes the existing

-//! The cues are functional signals (a fixed, documented event → byte

-//! **off by default**, so a platform with no sound support falls back to
-//! doing nothing.
-//!
-//! The decision function is pure with respect to wall-clock time: the
-//! caller supplies `now_ms`, so rate limiting is deterministic and
-//! testable. The runtime clock used by the wiring in
-//! [`super::notifications::notify_done_to`] is
-//! [`std::time::SystemTime`] epoch millis ([`epoch_millis_now`]) — not
-//! strictly monotonic, but fine for rate limiting, and documented here

+# Signed cloud facts
+
+Cloud facts are an optional signed overlay for model metadata and unset provider
+model defaults. They are **off by default**. The production trust tables in Rust
+and the website are empty, so enabling the setting currently reports an inert
+layer and does not fetch or trust a production channel.
+
+This source slice does not establish a deployed endpoint, published database
+row, signing-key custody, or a real provider request. The JSON under
+`docs/cloud-facts/stable.json` is unsigned authoring material; its release entry
+matches the checked-in `web/data/latest-published-release.json` receipt. It is
+not a publication receipt. Public test fixtures establish local behavior only.
+
+Related: [catalog refresh](CATALOG_REFRESH.md) and [provider routes](PROVIDERS.md).
+
+## Authority and configuration
+
+```toml
+[cloud_facts]
+enabled = false
+channel = "stable"
+ttl_hours = 6
+```
+
+`CODEWHALE_CLOUD_FACTS=1|0` overrides the setting;
+`CODEWHALE_DISABLE_CLOUD_FACTS=1` is the hard disable. Channel, URL and local
+signed-envelope overrides are `CODEWHALE_CLOUD_FACTS_CHANNEL`,
+`CODEWHALE_CLOUD_FACTS_URL` (optional `{channel}` placeholder) and
+`CODEWHALE_CLOUD_FACTS_PATH`. A local file is still subject to all trust checks.
+Production network refresh is suppressed in CI; tests opt into an explicit
+loopback fixture transport policy.
+
+Loading a config object is structural. Accepted startup/reload settings admit
+one process-wide source generation. A refresh captures that generation before
+work and must still own it to publish either memory or disk state. Disabling or
+changing the source invalidates earlier work, clears the prior overlay and
+invalidates catalog readers. Hard disable also blocks local-file/cache reads,
+new network work, cache writes and a late refresh's publication.
+
+Startup can read a bounded regular cache file and launch a background refresh;
+network success is never a startup dependency. Missing, rejected, inapplicable
+or expired facts leave the remaining catalog authorities usable. Status reports
+whether facts are off, inert, verified, rejected or unavailable through the
+existing compact catalog/status surface.
+
+## Verification and expiration
+
+The `facts/v1` envelope contains exact base64 payload bytes, their SHA-256,
+Ed25519 signatures and repeated metadata. The signed message is:
+
+```
+"codewhale-facts/v1\0" || key_id || "\0" || payload_bytes
+```
+
+Clients verify bounded envelope/payload sizes, supported envelope and algorithm,
+an active pinned key, signature and digest, signed/outer metadata agreement,
+channel, schema, semantic-version applicability and the accepted version floor.
+The key ID participates in the signature. Rotation can carry extra signatures;
+at least one active approved key must verify. A database key registry is not a
+trust root.
+
+Publication, expiration and announcement dates must be valid UTC timestamps.
+Future publications are rejected outside the bounded clock tolerance. Signed
+expiry is never extended by a successful refresh or `304`. The client's stated
+48-hour expiry grace is included in the scoped validity bound; after that bound
+facts are stale and cannot supply catalog prices or defaults. The public relay
+rejects expired delivery. Per-item applicability and announcement windows are
+re-evaluated when cached data is reused.
+
+A `304` authenticates nothing by itself: cached bytes must re-verify against the
+current keys, channel, binary version, rollback floor and clock. Cache and ETag
+identity are partitioned by source/channel, and channel rollback protection
+survives a source change. HTTP bodies, outer disk cache records and labels are
+bounded; cache/local readers reject symlinks, non-regular files, multiply linked
+files and oversized input. A failed or untrusted response cannot become a new
+catalog authority.
+
+## Catalog and cost behavior
+
+The existing compiler inserts cloud facts at layer 15:
+
+```
+0 bundled Models.dev < 5 bundled Codewhale < 10 live Models.dev
+< 15 verified cloud facts < 20 provider-owned live < 25 Codewhale account
+< 30 config < 40 user overrides < policy DENY
+```
+
+An upsert patches specified metadata fields. Creating a row requires its context
+window. Deprecation annotates; hide only removes lower bundled/Models.dev rows.
+Cloud data cannot delete provider-live, account, config or user rows.
+
+Capability and price provenance are independent. A capability-only patch keeps
+the original price source. A cloud price block replaces all token classes
+atomically; omitted cache/input/output classes remain unknown. The source
+records signed facts version, verifying key, fetch time and validity bound.
+Mutable cloud prices are frozen with the exact dispatch route and persisted
+with the existing cost receipt. Later refresh/disable cannot reprice that turn,
+and an old receipt with no frozen cloud quote cannot borrow a later cloud price.
+Provider-owned billing tiers, subscription/local surfaces and routing-dependent
+prices retain their existing checks.
+
+Cloud model defaults are consulted only when no explicit selection or stronger
+provider/account roster applies, through the normal route resolver. Codex model
+availability and Ollama endpoint tags retain their own authority. Cloud data
+cannot introduce a provider implementation, billing owner or wire protocol.
+A cloud `base_url` field is accepted only by the shared static public HTTPS
+endpoint contract; it is not consumed to migrate an execution endpoint.
+
+## Website transport
+
+`web/app/api/facts/v1/[channel]/route.ts` implements GET/HEAD for the public
+channel. It reads `facts_current` over PostgREST using only the publishable
+Supabase key, validates the complete signed envelope and caches only verified
+responses. Existing `CURATED_KV` can retain a last-good copy, which is bounded
+and revalidated under the same current trust/time rules before stale fallback.
+
+With no active pinned key, delivery fails closed. Missing connection settings,
+invalid upstream data or unavailable backing storage produce explicit errors.
+HEAD responses, including errors, have no body. A strong ETag binds the complete
+verified envelope, including signatures, so trust-material changes cannot reuse
+an old representation validator. Conditional requests do not bypass validation.
+
+Required deployment configuration, if separately authorized, is `SUPABASE_URL`
+and `SUPABASE_PUBLISHABLE_KEY`. A service-role credential never belongs in the
+website. `facts_current` must be a read-only view with explicit SELECT grants,
+RLS and policies limited to published public channels. This repository slice
+performs no remote schema, grant, key, or data mutation; those controls require
+separate deployment evidence.
+
+## Authoring and public fixtures
+
+`web/scripts/check-cloud-facts.mjs` checks the unsigned source, release receipt,
+Rust/web key-table equality and the public signed fixtures. It distinguishes a
+valid empty trust table from a parser failure and rejects fixture trust anchors.
+
+`web/scripts/facts-publish.mjs` supports validation, key generation, signing,
+verification, SQL generation and publication. Signing/publishing are operator
+actions requiring the relevant authority. Production verification/signing
+requires an active pinned key; explicit fixture verification is separate. Key
+generation creates a new private file exclusively, and CI signing is rejected
+before any private-key read. Numeric version fields must be safe positive
+integers before SQL or publication. Do not use real private keys in a repository,
+logs or test fixtures.
+
+`docs/cloud-facts/fixtures/test-only-signing-key.pem` is deliberately public and
+has one exact GitGuardian path exception. Its public key is never pinned in a
+production table. Tests may sign synthetic payloads using that fixture or an
+ephemeral in-memory test key. No fixture signature establishes production trust.
+
+To activate a future channel: approve key custody and its public anchor, update
+both trust tables, verify and ship that anchor, then separately approve signing
+and publication. Before signing, choose a facts version above the channel’s
+verified published floor; the unsigned source version is not a live-channel receipt. Rotation pins the next key before dual-signing and retiring the
+old key; there is no in-band command that can install or expand trust anchors.
+
+Release notices and announcements are represented and scoped but do not replace
+the existing release checker or introduce announcement rendering in this slice.
+Organization-specific trust, automated publication and endpoint migration are
+not implemented.

+### OpenRouter vendor pinning
+
+OpenRouter serves each model through several upstream vendors, and Codewhale
+can pin requests to a vendor with `[providers.openrouter] vendor` (#6007):
+
+```toml
+provider = "openrouter"
+[providers.openrouter]
+model = "deepseek/deepseek-v4-pro"
+vendor = "deepinfra" # copy the vendor slug from the model's OpenRouter page
+```
+
+This sends `"provider": {"order": ["deepinfra"], "allow_fallbacks": false}`
+on OpenRouter requests. A base slug can match multiple endpoint variants;
+copy a full slug such as `deepinfra/turbo` to select one variant. An unavailable
+pin fails at OpenRouter. Codewhale's separate `fallback_providers` setting can
+still switch the whole route after a recoverable error.
+
+The pin applies across OpenRouter models, including auxiliary requests on that
+route. Set `vendor = ""` to clear it. Reload config or restart to apply edits;
+requests already in flight keep their captured route. Other providers do not
+inherit the pin. `/preview-request` shows the primary request's routing fields.
+
+Model strings still pass through verbatim: `:floor` sorts by price, `:nitro`
+sorts by throughput, and `@preset/my-team-preset` references an account preset.
+See OpenRouter's [provider routing](https://openrouter.ai/docs/guides/routing/provider-selection)
+and [presets](https://openrouter.ai/docs/guides/features/presets) documentation.
+Codewhale does not fetch per-vendor endpoint prices or availability; pinned
+usage reports a routing-dependent unknown cost instead of a catalog estimate.

+- `[notifications]`: notification delivery, attention, categories and audio share one
+  policy. `quiet = true`, `method = "off"`, `condition = "never"` and disabled
+  categories suppress both the banner and Codewhale's selected sound.
+- `notifications.method`: `auto` (default), `osc9`, `kitty`, `ghostty`, `bel`, `off`.
+- `notifications.condition`: `unfocused` (default), `always`, `never`. When absent,
+  the legacy `tui.notification_condition` remains the fallback. `always` also
+  bypasses the duration threshold; `unfocused` requires two seconds away.
+- `notifications.threshold_secs`: nonnegative integer, default `30`.
+- `notifications.include_summary`: boolean, default `false`.
+- `notifications.sound`: optional `off`, `whale`, `bell`, `beep`, `file`.
+  A selected value controls audio across enabled categories. Absent keeps legacy
+  `completion_sound` and `event_sound` choices; `off` overrides both.
+- `notifications.sound_file`: custom local WAV path for `sound = "file"` or legacy
+  `completion_sound = "file"`.
+- `notifications.subagent_completion`: `always`, `final-only` (default), `off`.
+- `notifications.quiet`: boolean, default `false`.
+- `notifications.events`: six boolean categories, all enabled by default; see below.
+- `notifications.completion_sound`: legacy completion cue, default `off`, with the
+  same values as `sound`. Used only when `sound` is absent.
+- `notifications.event_sound`: legacy `enabled` (default `false`), `events`
+  (default `["turn-complete", "approval-needed"]`), and `quiet` (default `false`).
+  `min_interval_ms` (default `2000`) applies to each category's audio in both modes.
 - `tui.alternate_screen` (string, optional, default `auto`): which screen an interactive session starts on. `auto` and `always` start on the TUI-owned alternate screen; `never` starts in inline mode — a ratatui viewport the full height of the terminal with no alternate screen, so the shell's scrollback survives the session and stays scrollable after exit. `/fullscreen` and `/inline` switch it in-process; a switch that the terminal refuses rolls back and says why. Inline mode paints the whole transcript inside its viewport — nothing is written into the host scrollback while the session runs.
 - `tui.mouse_capture` (bool, optional, default `true` on non-Windows terminals and on Windows Terminal/ConEmu/Cmder when the alternate screen is active; `false` on legacy Windows console and inside JetBrains JediTerm — PyCharm/IDEA/CLion/etc. — where mouse-event escapes leak into the input stream as garbled text, see #878 / #898): enable internal mouse scrolling, transcript selection, right-click context actions, and transcript scrollbar dragging. TUI-owned drag selection copies only transcript text, removes visual wrap-column line breaks from paragraphs, and keeps selection scoped to the transcript pane. Set this to `false` or run with `--no-mouse-capture` for raw terminal selection; set it to `true` or run with `--mouse-capture` to opt in anywhere it's defaulted off. On raw terminal selection, especially on legacy Windows console or when mouse capture is disabled, selection may cross the right workbar and include visual wraps because the terminal, not the TUI, owns the selection.
 - `tui.terminal_probe_timeout_ms` (int, optional, default `500`): startup terminal-mode probe timeout in milliseconds. Values are clamped to `100..=5000`; timeout emits a warning and aborts startup instead of hanging indefinitely.
 - `tui.stream_chunk_timeout_secs` (int, optional, default `900`): per-SSE-chunk idle timeout for streamed model responses. Slow local or compatible servers can raise this with `/config stream_chunk_timeout_secs <seconds>`; `0` maps to the default and explicit values must be `1..=3600`. The legacy `DEEPSEEK_STREAM_IDLE_TIMEOUT_SECS` env var is still honored when this key is omitted.
 - `tui.header_items` (array of strings, optional, default `[]`): opt-in header chips. Set `header_items = ["tokens"]` under `[tui]` to show the session input, cache-hit, and output token counts. Narrow terminals elide the optional chip; wide terminals show it alongside context utilization.
 - `tui.osc8_links` (bool, optional, default on for macOS/Linux, off for Windows): emit OSC 8 escape sequences around URLs in transcript output so supporting terminals (iTerm2, Terminal.app 13+, Ghostty, Kitty, WezTerm, Alacritty, recent gnome-terminal/konsole) can open them with the terminal's link gesture—usually Cmd-click on macOS and Ctrl-click on Linux/Windows. Terminals without OSC 8 support render the plain label and ignore the escape. The escapes are emitted out-of-band (not inside buffer cells), so column corruption is not a concern; set `false` only for terminals that misrender the OSC 8 terminator itself. Windows legacy consoles default off; opt in with `true`.
+- `tui.max_model_steps` (int, optional, default uncapped): optional model-step ceiling for one ordinary turn. Omission or `0` leaves model steps uncapped; explicit positive values are clamped to `1..=100000`. Headless `exec` and Fleet workers also have no implicit model-step ceiling; `exec --max-turns N` and positive worker budgets still apply. At ~80% of an explicit step budget the model gets one soft-landing notice; at exhaustion the turn ends `Failed` with `Maximum model steps reached before completion (limit: N)` after one bounded final-report response when needed. Cumulative wall-clock and per-stream limits remain independent. Active interactive goal turns use `goal.max_steps` instead (default `1000`); see the Goal loop section below.
+- `tui.turn_wall_clock_secs` (int, optional, default `3600`): cumulative per-turn wall-clock budget in seconds, measured across every model step of one turn (not per request). Time blocked on a human approval is excluded. Clamped to `30..=86400` (24 hours is the documented ceiling); `0` resolves to the default. When exhausted the turn stops before authorizing another billable request with a message naming the limit and the key to raise.
 - `transcript.prose_measure` (positive integer, optional, default absent = full width): wrap cap, in columns, for prose cells — user messages, assistant answers, and reasoning/thinking blocks — in the live transcript (#5436). Absent (or `0`) spends the full content width, consistent with tool/status cells and the #5322 wide-frame decision; the former 105-column prose rail is gone. Set a positive whole number (e.g. `prose_measure = 120` under `[transcript]`) to restore a bounded reading measure on ultrawide terminals. Narrow terminals always keep their content width — the cap clamps from above only. Tool, diff, and status cells never inherit this cap. Invalid values (negative or non-integer) are rejected at startup with a `transcript.prose_measure` config error. Resolved once per render pass, so the main transcript cache and the full-screen overlay always agree on the effective width.

 ### Notifications
 
-The TUI can emit a desktop notification (OSC 9 escape or plain BEL) when a turn **completes successfully** and took longer than a threshold, so you can tab away while a long task runs. Failed or cancelled turns are intentionally silent — the notification is a "your task is ready" cue, not a generic ping. Configuration lives under `[notifications]`:
-
-```toml
-[notifications]
-method          = "auto"  # auto | osc9 | bel | off
-threshold_secs  = 30      # only notify when the turn took >= this many seconds
-include_summary = false   # include elapsed time + cost in the notification body
-completion_sound = "off"  # off | beep | bell | file; sound is opt-in
-sound_file = "E:\\google\\downloads\\notify.wav" # for completion_sound = "file"
-quiet = false             # true suppresses every desktop notification and sound
-
-[notifications.events]    # per-category switches; all default to true
-turn-complete     = true  # an agent turn finished
-subagent-terminal = true  # a sub-agent reached a terminal status
-approval-needed   = true  # a tool call is blocked on your approval
-input-needed      = true  # the agent asked a question and is blocked
-elevation-needed  = true  # the sandbox denied a tool and needs a decision
-model-notify      = true  # the model called the `notify` tool
+Notification controls are available in the existing `/config` settings view,
+from terminal commands, and through the CLI. All write the same `config.toml`
+keys. Terminal changes apply immediately; add `--save` to keep them. CLI writes
+apply when the next process loads its configuration.
+
+```sh
+codewhale config set notifications.sound whale
+codewhale config set notifications.events.approval-needed false
+codewhale config set notifications.quiet true
+codewhale config get notifications
+codewhale config unset notifications.quiet
 ```
 
-`quiet = true` is the one-flag "stop interrupting me" switch: it silences
-every category on every delivery mechanism while leaving the rest of your
-notification configuration intact, so flipping it back restores your exact
-previous policy. `[notifications.events]` disables single categories the
-same way — a disabled category is suppressed at the emission path, so it
-cannot leak through one specific protocol. A suppressed notification also
-suppresses its paired `[notifications.event_sound]` cue (no orphaned bells
-for events you turned off). The turn-completion chime also respects `quiet`.
-
-Method semantics:
-
-- `auto` (default) — picks a supported native or terminal banner transport. Unknown terminals fail closed to `off`; automatic banner selection never invents a BEL sound.
-- `osc9` — emit `\x1b]9;<msg>\x07`. Inside tmux the sequence is wrapped in DCS passthrough so it reaches the outer terminal.
-- `bel` — emit a single `\x07` byte. Use this on Windows only if you actively want the chime back.
-- `off` — disable banners. An explicitly selected completion sound remains an independent control.
-
-By default, delivery is background-only: Codewhale waits until the terminal
-has remained unfocused for two seconds. Set `notification_condition =
-"always"` under `[tui]` to allow configured notifications in the foreground,
-or `"never"` to suppress all operator notifications. macOS native banners are
-silent. `completion_sound` controls the turn-completion cue; the separate,
-opt-in `[notifications.event_sound]` table controls event BEL cues. Explicit
-`method = "bel"` is also audible and should be used only when that is wanted.
-
-Windows users who run inside a known OSC-9 terminal (e.g. WezTerm on Windows) keep getting OSC-9 notifications. Set `method = "off"` to disable threshold-based desktop notifications entirely.
+```text
+/config notifications sound whale --save
+/config notifications condition unfocused --save
+/config notifications quiet true
+/config notifications status
+```
 
-`completion_sound = "file"` is for Windows users who want a per-application
-completion sound without changing the global Windows sound scheme. It plays the
-configured WAV `sound_file` asynchronously via the native Windows audio API.
+Nested CLI edits preserve TOML types, unrelated keys and comments. Unset removes
+only the selected leaf. `notifications.sound legacy` in the TUI, or CLI unset of
+`notifications.sound`, restores previous sound choices. Invalid values are
+rejected before file or session changes. In an active TUI profile, saved edits
+update its notification table when it owns one; otherwise they update the
+inherited root table. The settings detail keeps saved and current values distinct.

-`[notifications.event_sound]` is an opt-in, deterministic policy that emits a
-terminal-bell-level cue when specific notification events fire (approval
-prompts, blocked-on-input, sub-agent completion, and so on). It is **off by
-default**; with `enabled = false` nothing is emitted, which is the
-platform-safe no-op fallback.
+`quiet = true` mutes every category without changing saved choices. `method =
+"off"` also stops both banner and selected audio. Disabling a category stops its
+sound. Attention and duration gates apply before any sink runs. Title animation
+completion is silent; only the authorized notification event can request audio.
+Successful turn completion is a notification category; failed/cancelled turns do
+not create a success notification.
+
+`auto` chooses a recognized terminal protocol or the existing macOS native
+fallback; unknown terminals remain unsupported and never invent a bell. `bel`
+is an audio-only transport: one selected cue is dispatched, without a second
+transport bell. With `sound = "off"`, that transport is silent. `osc9`, `kitty`
+and `ghostty` use their terminal notification protocols; tmux passthrough is
+preserved. Terminal/OS notification preferences still govern display, attribution
+and any sound the host itself adds.
+
+By default the terminal must stay unfocused for two seconds. `condition =
+"always"` allows foreground notifications and bypasses the duration threshold;
+`"never"` suppresses all delivery. The canonical condition takes precedence over
+legacy `[tui].notification_condition`.
+
+The bundled `whale` is a 1.55-second original whale-inspired cue, with no
+third-party recording. It remains an opt-in candidate pending listening approval.
+WAV playback uses a background worker: macOS `/usr/bin/afplay`, Linux `aplay`
+from [ALSA utilities](https://github.com/alsa-project/alsa-utils), or Windows
+`PlaySoundW`. A missing player/file or unsupported platform has no fallback bell.
+Only one WAV plays at a time. A worker-start receipt is a dispatch attempt, not
+proof of audible playback or OS acceptance. The existing macOS `osascript`
+banner retains Script Editor attribution; this Core change does not provide a
+branded native Apps banner.
+
+#### Previous sound settings
+
+When `notifications.sound` is absent, completion uses a non-off
+`completion_sound` selection, and other events use the existing event allow-list.
+These are compatibility inputs to the same audio decision, not separate playback
+paths. When the global sound is selected, it takes precedence over the previous
+completion/event choices. The default remains silent unless a legacy sound or
+explicit `bel` transport was already selected.
 
 ```toml
 [notifications.event_sound]
-enabled = false                              # default: off (opt-in)
-events = ["turn-complete", "approval-needed"] # default allow-list
-min_interval_ms = 2000                       # per-event rate limit
-quiet = false                                # true silences everything without editing the allow-list
+enabled = false
+events = ["turn-complete", "approval-needed"]
+min_interval_ms = 2000
+quiet = false
 ```
 
-The cue table is fixed — cues are functional BEL-based signals, not
-designed-for-pleasantness audio, and every cue is one or two `\x07` bytes
-(inert on terminals that ignore BEL, so this is a platform-safe no-op
-everywhere):
+Legacy event cues use one bell for completion, subagent completion, input and
+model notices; approval/elevation cues use two. The per-category repeat interval
+survives settings refreshes. Old unknown event names are ignored on load; new
+CLI/TUI edits require names from the six categories above.
 
-| Event | Cue |
-|---|---|
-| `turn-complete` | BEL (`\x07`) |
-| `subagent-terminal` | BEL (`\x07`) |
-| `approval-needed` | double BEL (`\x07\x07`) |
-| `input-needed` | BEL (`\x07`) |
-| `elevation-needed` | double BEL (`\x07\x07`) |
-| `model-notify` | BEL (`\x07`) |
-
-Decision order: disabled → quiet mode → event not in `events` → `turn-complete`
-deferred to the `completion_sound` channel when that is active (so the two
-never double-ding) → per-event rate limit (`min_interval_ms` since the last
-play of that event) → play. Unknown strings in `events` are ignored.
+Local approval/input/elevation prompts and error receipts remain available when
+external notifications are muted. Action prompts use the selected UI language
+and retire when that request settles. Repeated live notices keep their first
+expiry; a later routine update does not hide an unresolved warning at completion.
+Optional plugin suggestion toasts and contextual tips share one session guidance
+budget. `/config contextual_tips off` hides those toasts while preserving

+
+## Model-bound redaction (`[redaction] model_bound`)
+
+Codewhale masks credential-looking values in tool output **before it is sent
+to an upstream model** — the "model boundary". A file read by a tool can
+contain a configured API key, a bare provider token, or a credential-shaped
+opaque string, and the model must not see those bytes. This backstop is
+separate from the display/export scrubbers: it decides what the model itself
+can quote back, and it is deliberately conservative (`CredentialShaped`
+policy, see `crates/config/src/persistence.rs`), so ordinary code and config
+stay byte-exact while keys, JWTs, bearer tokens, PEM blocks, and long opaque
+runs are masked.
+
+Turning that masking **off** is a security decision, so it is not a plain
+boolean:
+
+```toml
+[redaction]
+model_bound = "disabled"   # "enabled" (default) | "disabled"
+```
+
+Setting `"disabled"` only records a *request*. It takes effect only when all
+of these are true:
+
+1. You restart the interactive TUI.
+2. The startup gate appears and you press `1`/`Y` on its first stage
+   ("confirm and disable"). This only advances to a second, final-confirmation
+   stage - the gate repeats the red warning and asks "are you really sure?".
+3. On that second stage you press `1`/`Y` again. The gate is rendered with the
+   same explicit-key discipline as workspace trust - `Enter` never confirms by
+   reflex, and `2`/`U` on the second stage steps back.
+4. Only that second confirmation persists a receipt to
+   `~/.codewhale/redaction-state.json` (next to `config.toml`) and rebuilds
+   the engine with masking off for the rest of this launch and future ones.
+
+The receipt is bound to the config it was made against and is valid only
+while that config still requests `"disabled"`. Setting `model_bound` back
+to `"enabled"` - or rewriting `config.toml` in any way after the
+confirmation - invalidates it, so requesting `"disabled"` again later
+asks for a fresh confirmation on the next launch. The receipt checks both the
+config contents and modification time; missing, unreadable, or malformed config
+and older receipts without this binding keep masking enabled. Legacy-home
+installs store the receipt beside their resolved config file.
+
+Until a confirmation exists, the effective mode is always `"enabled"`:
+
+- Choosing `2`/`U` ("keep masking on") leaves the config field untouched, so
+  the next launch asks again. Edit the field back to `"enabled"` to stop being
+  asked.
+- Non-interactive entry points (`codewhale exec`, hooks, automations, headless
+  agents) never confirm anything and never apply an unconfirmed request.
+- Routing/classification summaries and durable goal-state text keep their own
+  always-on redaction regardless of this switch; the opt-out exists so the
+  model can quote file bytes for exact edits, not to relax stored state.
+
+The config value itself is forgiving: `true`/`false`, `"on"`/`"off"`, and
+`"enabled"`/`"disabled"` (any casing) all parse, with `false`/`"off"` meaning
+`"disabled"`.
+
+A confirmed opt-out still sends your configured API keys to the provider you
+are already talking to. Only use it when the model must read and edit files
+that contain real credentials.

-## The review key is a Codewhale key, not a vendor key
-
-The canonical secret is **`CODEWHALE_API_KEY`**. It is the key for *your
-Codewhale account*, and the model behind it is whichever one you configure as
-your Codewhale agent for GitHub — it is not tied to any single vendor.
-
-`.github/workflows/codewhale-review.yml` maps `CODEWHALE_API_KEY` into
-whatever environment variable the configured provider expects (a `case` over
-`CODEWHALE_REVIEW_PROVIDER`), so the secret name never has to change when you
-change models.
-
-Bring-your-own-key still works: set the provider's own variable instead and
-the workflow uses it directly, with no mapping.
-
-If `CODEWHALE_API_KEY` and a provider's own secret are **both** set, the
-canonical account key wins: the workflow maps it onto the chosen provider's
-variable, overwriting the BYOK value.
-
-| Secret                | Role                                                        |

-| `DEEPSEEK_API_KEY`    | BYOK fallback (DeepSeek). This is the DeepSeek *provider* variable — it is not a generic bot key |
-| `OPENROUTER_API_KEY`  | BYOK fallback (OpenRouter)                                   |
-| `ANTHROPIC_API_KEY`   | BYOK fallback (Anthropic)                                    |
-
-Any **one** of these is enough. Until at least one exists, the workflow skips
-itself with a green notice, so it is safe to merge before setup is finished.
-
-## Choosing which agent reviews
-
-Two repository variables (Settings → Secrets and variables → Actions →
-*Variables*) pick the route:
-
-| Variable                     | Example    | Effect                                        |
-|------------------------------|------------|-----------------------------------------------|
-| `CODEWHALE_REVIEW_PROVIDER`  | `zai`      | passed through as `codewhale review --provider zai` |
-| `CODEWHALE_REVIEW_MODEL`     | `GLM-5.3`  | passed through as `--model GLM-5.3`           |
-
-Both are optional. With neither set, the provider is inferred from which key is
-present (`CODEWHALE_API_KEY` alone defaults to the z.ai Coding Plan route) and
-the model is that provider's default — currently `GLM-5.3` against
-`https://api.z.ai/api/coding/paas/v4`.
-
-`--provider` matters because a model id can be reachable through more than one
-configured route. When it is, route resolution refuses to guess:
-
-```
-model `glm-5.3` is available from configured provider route(s): openrouter, zai.
-Pass `--provider <provider>` with `--model glm-5.3` to choose one explicitly.
-```
-
-In CI with exactly one key configured the ambiguity does not arise, but adding
-a second key would break the job. Setting `CODEWHALE_REVIEW_PROVIDER` pins the
-route so that never happens.
-
-## Output budget (reasoning models)
-
-GLM-5.3 is a reasoning model: it emits `reasoning_content` before any
-`content`, and both are charged against `max_tokens`. An undersized cap
-therefore produces an **empty** review rather than an error.
-
-The CLI's automatic cap (64K) already leaves plenty of room, so the workflow
-sets no override by default. To change it, set repository variable
-`CODEWHALE_REVIEW_MAX_OUTPUT_TOKENS`; the workflow exports it as
-`CODEWHALE_MAX_OUTPUT_TOKENS` and **rejects values below 8192** for exactly
-this reason. The run step also fails the job if the review comes back
-zero-length on a zero exit status, rather than reporting a clean review that
-never happened.
+## Account keys and provider keys
+
+`CODEWHALE_API_KEY` is a Codewhale account machine key (`cwc_key_…`), not a
+vendor credential. In account mode the workflow first runs
+`codewhale --no-project-config account agent` to check authentication and the
+account's configured agent. It then selects the existing `codewhale` provider,
+which sends that key to the Codewhale model relay. It never copies an account
+key into a vendor environment variable.
+
+Connect the underlying provider in your Codewhale account and create a machine
+key with `agent:run` and `models:infer` scopes. The default scopes from
+`codewhale account api-keys create --name github-review` also include
+`account:read`, which permits identity checks. Set `CODEWHALE_REVIEW_MODEL` to
+an exact `provider/model` id returned by your account's authenticated
+`GET /v1/models` catalog. The offline model defaults are bootstrap values, not
+proof of account access; see [Providers](PROVIDERS.md).
+
+Bring your own provider key by setting its secret instead of
+`CODEWHALE_API_KEY`:
+
+| Secret | Route |
+| --- | --- |
+| `CODEWHALE_API_KEY` | Codewhale account relay; requires an explicit account catalog model |
+| `ZAI_API_KEY` | z.ai Coding Plan |
+| `MODELSTUDIO_API_KEY` | Model Studio Token Plan |
+| `DEEPSEEK_API_KEY` | DeepSeek |
+| `OPENROUTER_API_KEY` | OpenRouter |
+| `ANTHROPIC_API_KEY` | Anthropic |
+
+If both account and vendor secrets exist, the workflow selects account mode
+and leaves every vendor variable unchanged. In this mode
+`CODEWHALE_REVIEW_PROVIDER` must be unset or `codewhale`; a conflicting value
+fails before review. To select BYOK, remove the account secret from this
+workflow's configuration.
+
+## Choosing the review route and model
+
+Configure repository variables under Settings → Secrets and variables →
+Actions → Variables:
+
+| Variable | Account mode | BYOK mode |
+| --- | --- | --- |
+| `CODEWHALE_REVIEW_PROVIDER` | Unset or `codewhale` | Explicit provider, such as `deepseek` |
+| `CODEWHALE_REVIEW_MODEL` | Required exact account catalog `provider/model` id | Optional exact model id; otherwise the provider's default |
+
+For BYOK without an explicit provider, the workflow chooses the first available
+key in this order: z.ai, Model Studio Token Plan, DeepSeek, OpenRouter,
+Anthropic. Set the provider explicitly when several keys are present.
+
+The workflow passes provider and model as global CLI flags before `review`,
+with `--no-project-config`. Account mode deliberately pins the relay route:
+the account agent precondition reports a configured provider, but does not
+supply an exact model id or a vendor credential to the runner.
+
+## Complete diffs and input limits
+
+The workflow checks out the event's pinned head SHA for same-repository PRs,
+and the pinned base SHA for fork PRs. It uses full history, fetches the base
+repository's PR head ref, and verifies both event commits and a single merge
+base. Fetching fork objects does not check out or execute their files, hooks,
+submodules, or filters. Checkout credentials are not persisted.
+[GitHub's checkout documentation](https://github.com/actions/checkout) describes
+`fetch-depth: 0` and `persist-credentials: false`.
+
+The shared collector uses the complete GitHub diff when available and a
+verified local Git diff when the API cannot provide it, including large PRs.
+It rejects a changed snapshot, unavailable history, or incomplete diff before
+review. Repository variable `CODEWHALE_REVIEW_MAX_CHARS` sets the input limit
+per pass (default **200000**, allowed range **1–8388608**). The collector also has
+an **8 MiB output** and **60-second command** bound; a character limit does not
+bypass those transport bounds.
+
+A complete diff requiring more than one configured-limit pass fails the job by
+default. It is never silently truncated or treated as a provider funding
+problem. Repository variable `CODEWHALE_REVIEW_MAX_PASSES` (default **1**,
+allowed range **1–64**) passes `--max-passes N` to the CLI. Raising it explicitly
+authorizes the workflow to run up to N ordered passes for a complete review,
+with additional provider cost and run time. Set it only after reviewing that
+budget; leaving it unset retains one pass. If any pass fails, no partial
+review is posted.
+Increasing the character limit is a separate input-budget choice and still
+requires a model with sufficient context.
+
+When the complete PR cannot fit the allowed pass count, keep the failed
+advisory check and record that the model review did not run. Do not turn an
+input-limit failure into a clean review. Maintainers can explicitly authorize
+bounded whole-PR passes, or review bounded paths with a trusted build using
+`review --base <base-sha> --path <path>` from a checkout pinned to the PR head.
+Local diff reviews also reject oversized input. Path scopes cannot use `--pr`
+or `--post`; their receipts cover only the selected paths.
+Record the exact base/head, included paths and diff fingerprints, findings,
+checks actually run, and remaining coverage. Separately review interactions
+across paths and inspect changed media. A file inventory or a passing test
+suite is not evidence that those source reviews completed. This fallback
+does not change repository rules or satisfy a required whole-PR review.
+
+## Output budget
+
+`CODEWHALE_REVIEW_MAX_OUTPUT_TOKENS` optionally sets the CLI's output budget
+through `CODEWHALE_MAX_OUTPUT_TOKENS`. Without it, the CLI chooses its automatic
+cap. The workflow rejects values below **8192** to leave room for reasoning
+and the final review. Provider accounting and supported limits vary; an empty
+response is not proof of any one cause. A zero-exit review with empty output
+fails the job.

+# Write your first Codewhale plugin
+
+> 阅读简体中文版：[zh_hans/PLUGIN_AUTHORING.md](zh_hans/PLUGIN_AUTHORING.md)
+
+Start with a skill: a Markdown instruction file inside a small plugin bundle.
+The [hello-codewhale example](examples/plugins/hello-codewhale/plugin.json)
+contains two files, declares no server or hook, and asks for no tool use.
+This walkthrough takes it from source files to a reviewed, enabled skill.
+
+## 1. Create the bundle
+
+Use the checked-in example, or create this directory outside an installed
+plugins directory:
+
+```text
+hello-codewhale/
+├── plugin.json
+└── skills/
+    └── hello/
+        └── SKILL.md
+```
+
+`plugin.json`:
+
+```json
+{
+  "$schema": "https://agent-plugins.org/schemas/plugin.json",
+  "name": "hello-codewhale",
+  "version": "0.1.0",
+  "description": "A minimal, explicitly invoked greeting skill."
+}
+```
+
+`skills/hello/SKILL.md`:
+
+```markdown
+---
+name: hello
+description: Greet the user when they explicitly try the hello-codewhale example.
+invocation: explicit-only
+---
+
+Respond with one short greeting in the user's language. Include the exact text
+`hello-codewhale:hello` so they can identify the example they invoked.
+
+Use only the conversation. Do not call tools, run commands, read or write files,
+or contact external services.
+```
+
+Codewhale finds `skills/` automatically. `explicit-only` keeps this example out
+of the model's automatic skill catalogue; you load it by name. See
+[Skills](SKILLS.md#invocation-and-alias-metadata) for invocation metadata and
+[Plugin bundles](PLUGIN_BUNDLES.md#manifest) for the authoritative manifest
+contract. Keep new native bundles in `plugin.json`; no second manifest is
+needed.
+
+## 2. Install, inspect, and trust
+
+Start Codewhale in the repository root. Enter these commands **inside the
+Codewhale session**, one at a time:
+
+```text
+/plugin install ./docs/examples/plugins/hello-codewhale
+/plugin validate hello-codewhale
+/plugin show hello-codewhale
+```
+
+For your own bundle, replace the install path with its directory. Installation
+copies it to `~/.codewhale/plugins/hello-codewhale/`, disabled and untrusted.
+Review the installed source, skill inventory, and permissions. This example
+should declare only Skills, with no MCP server, hook, or requested network host.
+
+The install review prints a command containing two full hashes:
+
+```text
+/plugin trust hello-codewhale <full-content-sha256>.<full-capability-sha256>
+```
+
+Run the exact command printed by your review; the angle-bracket text above is
+a placeholder. If you need a fresh review, use `/plugin trust hello-codewhale`
+without a token. Trust records the reviewed content and capability hashes and
+creates a runtime snapshot. It does not enable the plugin.
+
+```text
+/plugin enable hello-codewhale
+/skills hello-codewhale:
+/skills inspect
+```
+
+The skill is named `hello-codewhale:hello`: the bundle name qualifies the skill
+name. `/skills inspect` identifies its reviewed plugin snapshot.
+
+## 3. Invoke it and turn it off
+
+```text
+/skill hello-codewhale:hello
+```
+
+Codewhale confirms activation. Then send `Say hello.` as a normal message.
+The reply should be a short greeting containing `hello-codewhale:hello`.
+The example contributes instructions only; the reply still uses your selected
+model and its normal provider connection. The local install, review, and
+activation steps do not need a model call.
+
+```text
+/plugin disable hello-codewhale
+```
+
+Disabling removes the plugin's contributions while preserving its trust
+receipt. A subsequent `/skill hello-codewhale:hello` must not activate it.
+Enable it again when needed, provided its reviewed hashes still match.
+
+## 4. Iterate and review changes
+
+The installed bundle is a copy. Editing the example's original source does
+not update that copy. To try a changed local source, disable and uninstall the
+installed example, then install the source directory again:
+
+```text
+/plugin disable hello-codewhale
+/plugin uninstall hello-codewhale
+/plugin install ./docs/examples/plugins/hello-codewhale
+/plugin validate hello-codewhale
+```
+
+Uninstall removes the installed copy; it leaves the original example source
+alone. Review the new token, trust it, and enable it again. For bundles
+installed from a remote source, use `/plugin update <name>`; see
+[Installing plugins](PLUGINS.md#update-and-uninstall).
+
+When files in a discovered bundle change directly, `/plugin reload` refreshes
+the registry. Changed content invalidates the old receipt, even if you leave
+the version unchanged. Reload does not grant trust. Use `/plugin revoke <name>`
+to remove trust explicitly.
+
+## Add only the components you need
+
+All components use the same bundle review and existing Codewhale runtime:
+
+| Component | Authoring surface |
+| --- | --- |
+| Skills | `skills/<name>/SKILL.md`; [instruction and invocation contract](SKILLS.md). |
+| MCP | A sibling `mcp.json`; [bundle transport and credential rules](PLUGIN_BUNDLES.md#validation-both-formats). |
+| Commands | Markdown command files; [command metadata](architecture/command-dispatch.md#user-commands). |
+| Agent profiles | Fleet TOML profiles; [Fleet authoring](FLEET.md#authoring-agent-profiles-fleet-setup). |
+| Hooks | `HooksConfig` TOML files; [events and process behavior](HOOKS.md). |

+Do not place MCP server fields or arbitrary runtime entrypoints at the manifest
+root. LSP and native extensions can be inventoried but are not executable
+plugin adapters.

+permissions: repository instructions, permission rules, sandbox policy, and
+tool approval still apply. Keep credentials out of bundles and command
+arguments. Use the reviewed environment references documented in the
+[bundle validation contract](PLUGIN_BUNDLES.md#validation-both-formats) for MCP;
+read the separate [hook environment contract](HOOKS.md#the-hook-process-environment)
+before adding a hook.
+
+## Convert an existing plugin
+
+[`scripts/convert-plugin.py`](../scripts/convert-plugin.py) converts explicitly
+selected remote MCP declarations and portable Skills into a native bundle.
+It requires Python 3.10+ and PyYAML 6+; install those separately if absent.
+The converter installs no dependencies, scans no ambient configuration or
+credentials, makes no network requests, and executes no source code.
+
+### OpenCode
+
+Save this plain JSON as `opencode-mcp.json`:
+
+```json
+{
+  "mcp": {
+    "docs": {
+      "type": "remote",
+      "url": "https://example.invalid/mcp",
+      "oauth": false,
+      "enabled": false
+    }
+  }
+}
+```
+
+From the Codewhale repository root, run this in your shell:
+
+```sh
+python3 scripts/convert-plugin.py --format opencode-v1 \
+  --config ./opencode-mcp.json --name migrated-tools --output ./migrated-opencode
+```
+
+Choose `--format opencode-v2` for the `mcp.servers.<name>` layout, whose server
+flag is `disabled` instead of `enabled`. Select the format from the data;
+filenames and upstream branch names do not determine its version. Both formats
+require explicit `oauth: false`. Remote MCP output uses **Streamable HTTP only**;
+OpenCode's fallback to legacy SSE is not reproduced. For an SSE-only endpoint,
+author native `mcp.json` with `type: "sse"` and use the same review flow.
+
+When MCP servers are selected, configurations containing `tools`,
+`permission`/`permissions`, `agent`/`agents`, legacy `mode`, or `default_agent`
+are refused. These settings can restrict tool access beyond server enablement.
+Manually preserve those restrictions in Codewhale before supplying an MCP-only
+input; simply deleting the settings can widen access.
+
+JSONC comments and trailing commas are not
+accepted: provide a plain JSON copy containing the declarations you intend
+to port.
+
+### DeepSeek Harness (DSH)
+
+Save this static Cordis entry list as `dsh-mcp.yml`:
+
+```yaml
+- name: '@deepseek-ai/dsh-mcp-client'
+  disabled: true
+  config:
+    serverName: docs
+    transport: streamable-http
+    url: https://example.invalid/mcp
+```
+
+```sh
+python3 scripts/convert-plugin.py --format dsh \
+  --config ./dsh-mcp.yml --name migrated-dsh --output ./migrated-dsh
+```
+
+The DSH input may also be JSON, but must be the plain entry list, not a full
+profile or patch composition. Each row must name `@deepseek-ai/dsh-mcp-client`.
+
+### Review the result
+
+Both examples preserve disabled servers and use a placeholder endpoint. Replace
+the endpoint and change the source's enablement flag before reconverting when
+you are ready to connect. The output directory must be new, with an existing
+parent. Existing output is refused; rejected input leaves no output bundle.
+
+Add `--skill ./my-skill` for an explicitly selected directory containing
+`SKILL.md`, or `--skill ./my-skill.md` for a single file; repeat the option for
+more skills. `--config` is optional for a skills-only conversion. Skills require
+`name` and `description` frontmatter. `disable-model-invocation: true` becomes
+native `invocation: explicit-only`. Informational `license`, `compatibility`,
+and `metadata` fields are retained in `SOURCE_SKILL_METADATA.json` companion
+data. Companion files from selected skill directories are copied as data;
+review them and the instructions before loading the skill.
+
+Only exact OpenCode header references such as `{env:MCP_TOKEN}` become native
+`env_headers`; the converter never reads the variable's value. Literal headers,
+DSH header expressions, and URL file/environment substitution are refused.
+Configured timeouts must be whole seconds expressed in milliseconds, from
+`1000` through `3600000`. Omitted timeouts use Codewhale's defaults.
+
+Executable plugins and hooks, stdio servers, automatic OAuth, JavaScript,
+YAML aliases/tags, `__jsExpr`, and unsupported skill runtime fields (including
+`user-invocable: false`) require a manual port. Conversion does not reproduce
+another client's runtime or bypass Codewhale's credential and sandbox rules.
+
+Read the generated `CONVERSION.md`, `plugin.json`, `mcp.json` when present, and
+all selected skill files. Then use `/plugin install ./migrated-opencode` (or the
+DSH output path), `/plugin validate <name>`, and the same hash-bound trust and
+enable flow above. Conversion alone proves neither connectivity nor runtime
+compatibility; the output is not installed, trusted, or enabled.

-# Codewhale cloud-agent snapshot
-
-The sandbox a `/dispatch` run launches from is a Daytona **snapshot**
-built from this directory's `Dockerfile`, with the `codewhale` CLI
-preinstalled. Daytona's create-sandbox API launches from snapshots — a
-raw image is only ever a snapshot-build input — so "snapshot" is the
-correct and only restorable artifact class here.
-
-Why this exists (founder decision, 2026-08-29): the created sandbox must
-run `codewhale exec --auto` itself, authenticated as the dispatching
-account, resolving the account's configured model — dispatch → sandbox
-(own codewhale) → account identity → forge PR. The account identity is
-injected at create time as the `CODEWHALE_API_KEY` env var (a
-`cwc_key_…` machine token); no provider API key ever widens into the
-sandbox (BYOK stays local).
-
-## Build the snapshot (operator, once per codewhale rev)
-
-```sh
-daytona snapshot create codewhale-cloud-agent \
-  --dockerfile ./Dockerfile \
-  --cpu 2 --memory 4
-```
-
-- The default name `codewhale-cloud-agent` matches
-  `DEFAULT_CLOUD_AGENT_SNAPSHOT` in `crates/tui/src/cloud_dispatch.rs`;
-  a different name is set per host with `CODEWHALE_DISPATCH_SNAPSHOT`
-  (slug charset, ≤64 chars — an invalid override falls back to the
-  default).
-- Pin a rev with `--build-arg CODEWHALE_GIT_REV=<sha>` when the default
-  moves past the rev you verified.
-- Daytona snapshots deactivate after two weeks of disuse; reactivate
-  before reuse or create fails.
-- Resource sizing: the harness declares a one-hour turn budget; 2 vCPU /
-  4 GB is the floor the offline tests assume.
-
-## What the create call sends
-
-`LiveDaytonaLauncher::create_sandbox` POSTs to the provider's sandbox
-endpoint with:
-
-```json
-{
-  "name": "cw-<job-id>",
-  "snapshot": "codewhale-cloud-agent",
-  "env": { "CODEWHALE_API_KEY": "<account machine token>" },
-  "labels": { "codewhale.job": "<id>", "codewhale.forge": "<forge>", "codewhale.product": "dispatch" }
-}
-```
-
-Labels are applied via the provider's dedicated labels endpoint right
-after create (Daytona does not apply create-body labels); a labels
-failure tears the fresh sandbox down and fails the create truthfully —
-an unlabeled sandbox is spend the orphan reconciler can never find.
-
-## Machine tokens
-
-Minted from the web app (Account → API keys) or the CLI's cloud
-api-key surface; `cwc_key_`-prefixed, read-mostly scopes, revocable
-server-side. A confirmed dispatch without one refuses before any spend:
-the sandbox's codewhale would have no identity to run as.

+# Dependency maintenance
+
+Reviewed against the 0.9.13 Core dependency graph on September 8, 2026.
+This records maintenance decisions, not a security clearance or release test.
+
+The terminal Markdown renderer uses Syntect's embedded syntax and theme dumps
+with the existing fancy-regex backend. It does not load external syntax YAML,
+theme plists, or emit Syntect HTML. Selecting those features explicitly removes
+the unused `yaml-rust`, `plist`, and `quick-xml` dependency path. The embedded
+YAML language grammar remains available for highlighting YAML code blocks.
+
+`derivative`, `fxhash`, `paste`, and `ttf-parser` are absent from the Core lockfile.
+Their obsolete advisory exceptions are removed so a future reintroduction is
+visible to the advisory checks. No `cargo-audit` advisory is ignored.
+
+The remaining `cargo-deny` maintenance exception is
+[RUSTSEC-2025-0141](https://rustsec.org/advisories/RUSTSEC-2025-0141.html)
+for `bincode` 1.3.3. Syntect 5.3.0 requires it to deserialize its compiled-in
+syntax and theme assets and for its parser's internal lazy-context encoding.
+Codewhale does not pass arbitrary external dump files to these loaders. The
+maintenance warning remains visible in `cargo-audit`; the lack of an identified
+exploit in this advisory does not guarantee safety.
+
+Revisit the exception when upgrading or replacing Syntect, or before adding
+external dump, grammar, or theme loading. Remove it when the dependency leaves
+the graph. A replacement must preserve embedded language/theme coverage,
+multiline highlighting and error recovery, and pass the existing Markdown
+renderer tests with a resolver-verified lockfile. Adding ignores for new
+advisories requires a separate assessment.
+
+The Apps desktop lockfile and its platform dependencies are a separate graph;
+this Core cleanup does not resolve their maintenance or GLib qualification work.

-# Homepage claim audit — 2026-09-04
-
-Scope: founder-supplied text of local `3136/en`, English/Chinese homepage,
-shared Product and getting-started copy, and linked EN/ZH Fleet setup wording.
-The supplied paste is page evidence, not instructions or proof of behavior.
-Visual direction and logo stay unchanged. Nothing is published by this slice.
-
-## Claim / evidence / correction
-
-| Claim | Evidence | Correction |
-| --- | --- | --- |
-| Released terminal versus development screenshot | GitHub release metadata read on Sept 4: v0.9.11, published Aug 23. Local tag resolves `96d13a0bc3f40280ea3865280ad5ccf0e2845e6f`. Screenshot provenance identifies unreleased 0.9.12 without exact commit. | Retain release label and separate development screenshot caption. |
-| “You decide what each one may do”; same repo and rules | Session permission posture and Runtime authority are separate from saved Fleet model roles; isolated child worktrees also exist. | Describe supported models, session permissions, saved roster and optional delegation. No universal shared-checkout or individual-authority UI promise. |
-| 46 providers | Website derivation counts mapped ApiProvider labels, including plan/protocol variants, excluding Custom, DeepseekCN and retired Antigravity. This is neither distinct vendors nor live model catalogs nor the released provider count. Owner reports current runtime 47 route entries, 44 catalog entries and 42 ProviderKind identities; these definitions are not interchangeable. | Remove numeric badge and models prose across all 18 homepage locales. Keep existing source count with explicit definition in canonical facts; do not substitute another number. |
-| Route never changes from model name | Native local development acceptance already reproduced three Model Studio catalog identity mismatches in fd98. Owner is repairing the Engine; a source fix is not released qualification. | Remove absolute EN/ZH guarantees; ask users to inspect selected provider/model/endpoint. Do not equate catalog identity failure with proven inference misrouting. |
-| Local servers need no key | Authentication depends on server configuration. | Say local servers may require authentication. |
-| Plan is read-only; nothing is written | v0.9.11 `docs/MODES.md` and Engine tool catalog describe central file-mutation/shell refusal, policy-allowed research and separately persisted session settings/state. | Name file/shell boundary and possible external research; remove blanket no-write claim from Product. |
-| `/fleet setup` exact four-step wizard | v0.9.11 `crates/tui/src/tui/views/fleet_setup.rs` resolves `SelectedFleet` or `LegacyProfiles`. Selected named Fleet opens its editor. Legacy path chooses role/model, with optional thinking on review. | Keep command, make step optional and accurately describe both destinations. Shared homepage/guide and EN/ZH Fleet docs updated. No published binary interaction claimed. |
-| Install/auth commands | v0.9.11 source contains auth set provider handling and Fleet setup; GitHub assets include terminal Linux/macOS/Windows archives. | Keep commands and released terminal target statement. No fresh install, key write or provider call performed. |
-| Public web sign-in and same-session remote control available | Source routes and local fixtures exist. This audit has no deployed authenticated same-session task acceptance. | EN/ZH homepage/Product say development preview and explicitly unverified public remote control. |
-| Desktop alpha builds exist on three platforms | Local macOS Dogfood startup has a receipt; Linux/Windows downloadable Tauri artifacts are not established. Windows terminal installer is not Tauri desktop proof. | Describe tested local macOS development build and no released desktop app download. |
-| Nothing on this site can charge you | An absolute statement exceeds evidence and obscures provider billing. | State terminal needs no Codewhale account; provider usage belongs to the user's provider account; account creation does not purchase model access. |
-| Ask/Auto-Review/Full Access absolutes | Approval rules, saved posture and hard policy boundaries affect actual execution. | Product describes rule-based prompts/review and persistent hard boundaries; removes universal every-write and never-default claims. |
-
-## Evidence boundaries
-
-Read-only release metadata and asset inventory:
-`/tmp/cwa-app-parity-20260904/site-release-claims-v0911.json`.
-No release artifact was downloaded or executed during this slice. Git tag source
-is source evidence, not a fresh installed task acceptance. No authenticated
-public web flow, provider request, deployment, billing action or customer task
-was performed. Source/provider integration remains independently qualified by
-its owner.
-
-Numeric models prose is corrected in all homepage languages. Broader hero,
-availability and linked documentation claims outside EN/ZH remain unaudited in
-this slice and must not be treated as reviewed translations. The English and
-Chinese scope is deliberate; a passing locale shape check does not establish
-translation accuracy or truth across the rest of the site.
-
-## Verification
-
-Initial tests: 405 passed, 2 failed (old keyless-launch phrasing assertion and
-models-body placeholder parity). The old assertion now checks the narrower
-behavior; every homepage models paragraph no longer uses the ambiguous count.
-Final tests: 407 passed across 47 files, 0 failed.
-Further build/browser/critique receipts are recorded below when complete.
-
-Final validation: facts, 23-topic docs, locale/catalog checks passed; lint 0 errors and 2 pre-existing logo-image warnings; webpack production build generated785 pages. Parent inspected EN desktop and saved `/tmp/cwa-app-parity-20260904/screenshots/site-claims-en-desktop.png`.
-
-Isolated Impeccable A:25/32 applicable, specificity3/4. B ran the actual detector:0 findings; inspected EN desktop and390 screenshot. A had mobile screenshot timeouts and collected EN/ZH DOM evidence only; B did not complete Chinese browser verification. No complete bilingual visual QA claim. Reports: `/tmp/cwa-app-parity-20260904/site-claims-design.md` and `site-claims-detector.md`.
-
-Two bounded P2 refinements remain for the founder's newly requested hero-scale slice: mark the Fleet heading visibly optional and verify/fix the narrow install Copy control's out-of-bounds geometry. The copy audit is committed separately to release canonical facts ownership; this is not a declaration that the full homepage is polished. The newly requested replacement terminal capture and default-on/opt-out analytics policy are separate in-progress changes, not included in this commit.

-# Website usage counting: default-on, control on the privacy page — 2026-09-04
-
-Founder direction: usage analytics on by default unless disabled; controls and
-explanations live primarily in the app and in Codewhale itself; the website
-keeps privacy details and its own opt-out on the privacy page and does not
-make usage statistics a marketing topic.
-
-What changed on the website:
-
-- The foot-of-viewport consent sheet is gone. Counting (page views, docs
-  views, install copies, downloads as plain totals) is on by default; the
-  only stored state is the person's own choice under the historical
-  `cw-usage-consent` key, so an opt-out recorded under the earlier opt-in
-  policy still counts as off. Unreadable stored state fails closed.
-- The privacy page (`/legal/privacy#usage-counting`) hosts the status line
-  and the Turn off / Turn on control; the footer "Usage data" link points
-  there. Nothing records an acceptance on the visitor's behalf.
-- The envelope is schema 3 / notice 5 (`notice_version` replaces
-  `consent_version`), matching the runtime and the ingest's v3 contract.
-- Trust page, FAQ, roadmap, and `docs/public-surface-facts.json` now say
-  that 0.9.12 counts by default and discloses it, and that the published
-  0.9.11 release asked first. The privacy policy gains an "Anonymous usage
-  counting" section and its effective date moves to September 4, 2026.
-- Screenshot provenance: the hero capture is the founder's PNG
-  (2760x1494, SHA-256 `5a762fce…ecd0`) whose header reads
-  `v0.9.12 (15fe6983bfa5)`; facts now record that version and commit. The
-  README image `assets/screenshot.webp` is a lossless 1136x615 downscale of
-  the same capture. Both show a local dogfood build, not a published
-  release; Full Access is the capture's posture, not a default.
-
-Verification on this tree (local, no deployment, no provider call):
-
-- `vitest run`: 407 passed / 0 failed across 47 files.
-- `tsc --noEmit`: clean. `eslint .`: 0 errors, 2 pre-existing `<img>` warnings.
-- `check:locales` (incl. GT catalog check), `check:facts`, `check:docs`: PASS.
-- `next build --webpack` after a clean `.next`: success. A first build in a
-  `.next` shared with the running dev server produced an `en.html` that
-  referenced chunks from another build; the clean rebuild removed that and
-  is what was served for the browser check.
-- Browser check against the production build on 127.0.0.1:3137, Chromium,
-  EN and ZH at 390x844 and 1280x900: no consent sheet on the home page; the
-  home visit counts one `page_view` with no preference record written; the
-  privacy control shows "on (default)", Turn off writes
-  `{version:5,granted:false}` and clears counters and install id, Turn on
-  writes `granted:true`; footer link present; no horizontal overflow
-  (scrollWidth == clientWidth); no console errors. The page's one
-  `POST /api/product-telemetry` reached only the same-origin route, which
-  answers `disabled` without `CODEWHALE_TELEMETRY_INGEST_URL`.
-  Receipt: `scratch/takeover-20260904/website-default-on/privacy-browser-qa.json`
-  and screenshots beside it.
-
-Not proven here: hosted deployment, live ingest or PostHog delivery, and
-non-EN/ZH claim review of the remaining README translations.

-# Website/app alignment — local integration, 2026-09-04
-
-This isolated branch combines the preserved website redesign at e6bfc48ed
-(including 151d6dd9d) with the installer/guide integration at f78919e77.
-The original website worktree and its preview processes remain untouched.
-The merge preserves the original commit authorship; it is not a deployment.
-
-A bounded ownership check found only the older preview processes with that
-worktree as their working directory. Its recorded Claude session identifies
-authorship, not an active writer. Work continues in
-`/Volumes/VIXinSSD/CW/worktrees/cw-website-app-alignment-20260904`, branch
-`feat/website-app-alignment-20260904`.
-
-The merged homepage retains the illustrated paper-to-water treatment, serif
-headline, and founder-supplied terminal capture. The capture is labeled as a
-0.9.12 development build; its exact binary commit was not recorded. The
-published-release record remains 0.9.11. Web sign-in and /rc are distinguished
-from the development workbench; desktop is unreleased and cloud computers
-remain unavailable. Those source claims do not establish deployed acceptance.
-
-Two integration fixes accompany the merge:
-
-- The final homepage install CTA now uses the shared getting-started command,
-  avoiding an npm-first recommendation beside the GitHub-first guide.
-- The header uses the exact supplied logo PNG, with the existing wordmark.
-  SHA256: cb7e5ee63c22ca2aa7daffd10374f19ace838d8efe35a1bf5f28f750b38402aa.
-
-Local verification uses the website's scoped gate; the runtime repository
-has no root npm test/check:web scripts. The 47 website test files pass all
-398 tests. Facts, documentation, and locale checks pass; lint reports zero
-errors and two existing wordmark image warnings. No dependencies were
-installed: this isolated tree links the existing website node_modules.
-
-No auth callback, repository installation, model request, secret operation,
-AWS operation, publication, billing, DNS, or external contact was performed.
-The new app GitHub setup remains local-contract evidence, not a claim that a
-public GitHub Agent trigger has been qualified.
-
-Final polish also makes undecided consent dismissible without granting,
-removes first-arrival autofocus, keeps the complete disclosure expandable,
-preserves a light reading field behind hero copy, distinguishes the Local
-web client in EN/ZH, and gives the docs guide sequential steps. Native
-controls preserve keyboard access. Local GT catalog export used no API.
-
-Final production build passed with Next16.3.3/webpack; 398/398 tests and lint
-remain green (two existing wordmark warnings). Impeccable used isolated
-A/B reviews, then polish; the closed snapshot records scores and limits.
-
-Root inspected the final built EN/ZH home at390px: document client/scroll
-width375px, with15px browser scrollbar and no horizontal overflow. Desktop
-1280px client/scroll width1265px also matches. The Chinese guide uses one
-343px column and preserves the complete GitHub command plus codewhale doctor.
-Initial focus remains BODY; Escape removes the preference dialog; reopening
-from the footer still reports undecided and focuses Close. No consent grant
-or analytics transmission was attempted.
-
-Preview: http://127.0.0.1:3136/en (own process, left running).
-Screenshots under /tmp/cwa-app-parity-20260904/screenshots/:
-site-aligned-en-390.png, site-aligned-zh-390.png,
-site-aligned-guide-zh-390.png, site-aligned-en-desktop.png.
-Native screenshot capture can crop the desktop panel; the DOM measurements
-above, rather than screenshot edges, establish document containment.

-# Website ingestion bound and install priority — 2026-09-04
-
-Follow-up to the local website integration e71e57376. The existing form stream
-reader now lives in `web/lib/bounded-body.ts`; both login forms and the telemetry
-forwarder consume it. Form media-type handling and `FormBodyError` remain intact.
-The reader counts raw bytes before retaining each chunk, cancels on overflow,
-releases its lock, and returns a controlled error for failed reads. Telemetry
-uses fatal UTF-8 decoding and never forwards rejected input. The exact canonical
-ingest setting, closed schema, consent path, no redirects, and no retries remain
-unchanged. Comments now distinguish headers set in source from headers the
-hosting transport could add; this is not a claim of network anonymity.
-
-Homepage availability text in all 18 locales, product availability, installation
-metadata/details, docs task descriptions, and EN/ZH FAQ installation answers now
-put GitHub release binaries first. npm and Cargo are alternatives. The FAQ reuses
-the existing getting-started command. Local GT export updated EN/ZH catalogs;
-no translation service was called. Mirror-specific and package-update recipes
-remain labeled alternatives.
-
-## Local proof
-
-- Website tests: 47 files, 407 passed, 0 failed. Nine added checks cover streaming
-  overflow without length and with misleading lengths; cancellation and lock
-  release; UTF-8 byte size; exact 4096-byte valid payload; malformed UTF-8 and
-  lengths; read failure; and split multibyte form data at its exact byte boundary.
-  Rejected telemetry cases assert zero forwarding.
-- Lint: 0 errors, 2 existing wordmark image warnings. Production webpack build,
-  locale/catalog checks, facts check, and docs check passed.
-- Initial test run exposed stale local GT exports (405 pass / 1 fail); exporting
-  the local catalogs resolved it. Final log is `site-byte-tests.log`.
-- Built preview `http://127.0.0.1:3136/en`: EN desktop and ZH 390px homepage copy
-  verified in the DOM; expanded EN FAQ verified at 390px. Document scroll/client
-  widths match (1265 desktop; 375 within a 390px viewport with scrollbar).
-- `/tmp/cwa-app-parity-20260904/screenshots/site-byte-en-desktop.png`,
-  `site-byte-zh-390.png`, `site-byte-faq-en-390.png` were captured and inspected.
-  Consent was dismissed without granting counting. No installer was executed.
-
-This runtime repository has no root `npm test` / `check:web` scripts; the website

-# Website installation guide — local receipt, 2026-09-04
-
-Branch `fix/site-github-install-guide-20260904` is based on the installer owner's
-public candidate `cdad345275809aabe38561ee2b2b17bd4a5806b8`. It preserves that
-candidate and the separately owned website redesign branch. No installer,
-release fact matrix, credentials, hosted service or release artifact was changed.
-
-The shared EN/ZH getting-started content now leads with the direct installer
-for a published GitHub release on macOS/Linux, mentions `codewhale update` for
-later updates and retains npm/Cargo as alternatives in the full guide. It
-explicitly distinguishes local development builds. The current published-release
-record remains v0.9.11; the separately installed local v0.9.12 build is not a
-publication receipt and is not substituted into public release facts.
-
-The longer command exposed an intrinsic-width defect in the existing step
-grid. Scoped `pre-wrap` and `overflow-wrap: anywhere` keep the complete command
-visible without inserting actual line breaks into it or adding another control.
-The existing content assertion now compares the first command with the canonical
-public install recommendation instead of pinning npm-first copy.
-
-## Verification
-
-- Production Next.js **16.3.3** build with webpack passed.
-- Website suite: **46 files, 386 tests passed, 0 failed**.
-- Facts check and all **23** documentation topics passed.
-- Lint: **0 errors, 2 existing image warnings** in nav/footer.
-- Regression negative control: the previous npm-first content fails the exact
-  recommendation assertion (**1 failed, 10 skipped**); restored content passes
-  (**1 passed, 10 skipped**). No installer/update command was executed.
-- Dual-agent Impeccable review: **21/28 applicable points**, no P0/P1, detector
-  **0** findings. A and B independently found the narrow command-width issue.
-  After polish, CUA measured EN/ZH at **390×844**: grid and pre both **343px**,
-  pre scroll/client widths both **341px**, right edge **359px** within the
-  **375px** content viewport (15px desktop scrollbar). Command text remained
-  exactly `curl -fsSL https://codewhale.net/install.sh | sh` followed by
-  `codewhale doctor`. All four command boxes also had equal scroll/client widths
-  at the default **1280px** desktop viewport. Localized guide links were keyboard
-  reachable with visible focus. The baseline snapshot was read and closed after
-  the built polish check; no new score or repeated detector run is claimed.
-
-Runnable preview: `http://127.0.0.1:3135/en/docs/guide` and
-`http://127.0.0.1:3135/zh/docs/guide`. Next is served from this worktree with
-`node node_modules/next/dist/bin/next start --hostname 127.0.0.1 --port 3135`
-inside `web/`. Installed dependencies were reused locally; none were downloaded.
-
-Logs: `/tmp/cwa-app-parity-20260904/site-guide-final-tests.log`,
-`site-guide-final-build.log`, `site-guide-final-lint.log`, `site-guide-facts.log`,
-`site-guide-docs.log`, `site-guide-negative-control.log`, and
-`site-guide-regression.log`. Screenshots: `screenshots/site-guide-en-390.png`,
-`site-guide-zh-390.png`, and `site-guide-final-desktop.png` under that directory.
-Temporary viewport overrides were reset; reviewers closed their own Guest tabs.
-
-This is a narrow source/copy and local browser receipt. Hosted CI, deployment,
-actual public download/update, and customer installation remain unproven. The
-complete website and unchanged guide steps were not re-audited in this slice.

-注意解析器和对外公布的 schema 对 `agent` 的 `max_depth` 看法不一致：解析器钳制到 8（`tools/subagent/mod.rs:10601-10617`），而展示给模型的 JSON schema 声明 `"maximum": 3`（`mod.rs:6845-6848`）。因此模型无法请求运行时愿意兑现的深度。这里作为代码差异跟踪，而不是文档差异。

 fleet 账本持久化的是 worker 自身的事件流，而不是另一套模拟的分类法。`codewhale exec --output-format stream-json` 会发出 `{"type": "content" | "tool_use" | "tool_result" | "sandbox_denied" | "workflow_event" | "session_capture" | "turn_usage" | "metadata" | "done" | "error"}` 行，它们映射到 fleet 账本的 `FleetWorkerEventPayload`（`RunningTool`、`WorkflowEvent`、`Running`、`Completed`、`Failed` 等）。`workflow_event` 在 Workflow 飞行期间携带类型化的 run/phase/task/gate 回执，并作为类型化的 `WorkflowEvent` 保留在 Fleet 账本中；外层 worker 仍然拥有终态 `done` 或 `error`。一套词汇，两个表面。
 
+`session_capture` 在 exec 运行把自己的对话记录持久化为已保存会话时发出一次，并且只在这一个地方携带可恢复的 id：

+ "content": "<redacted:…>", "saved_session_id": "01J…"}
+```
+
+- `saved_session_id` 只在会话成功保存后发出。本地 Fleet worker 使用父进程分配的新 id 和 Runtime 现有的会话目录；只有返回的 id 与分配值一致且记录可读取时，执行器才设置 `FleetReceipt.saved_session_id`。有 Runtime API 访问权限的客户端可通过 `GET /v1/sessions/{id}` 读取回复。SSH worker 保留摘录和远程日志，但不会声称存在本地会话链接。id 只是查询键，不能替代 Runtime 身份验证。
+- `content` 是与终态 `metadata.session_id` 相同的脱敏指纹，因此单独截获的 `metadata` 回执仍然可以安全写入日志，两个事件之间也仍可关联。相应地，`metadata.resume_command` 指向该字段（`codewhale exec --resume <session_capture.saved_session_id>`），而不是自己携带 id。
+
+终态 `metadata` 回执还携带 worker 可见的最终回答：`visible_final_answer_chars` 是最终助手回复的真实字符数，`visible_final_answer_excerpt` 是它的有界（4,000 字符，截断时以 `...` 结尾）、已脱敏的摘录；当前轮没有产生可见回答时省略该字段，恢复会话不会重用上一轮的回复。失败或中断的回执可以保留当前轮的部分文本，以回执状态为准。Runtime 执行器从这个回执读取摘录——绝不从流式 `content` 增量读取，那是运行过程中的"边想边说"——并把它附加到 `Completed.summary`；对于没有评分器也没有文件工件的任务，还会作为任务的交付物写入回执备注。生命周期事件标签和 worker 检视摘要只显示短摘录；事件 `payload` 和回执保留完整摘录。

+# 编写你的第一个 Codewhale 插件
+
+> 英文原文：[PLUGIN_AUTHORING.md](../PLUGIN_AUTHORING.md)。
+> 最后与英文同步日期（last synced with English revision）：2026-09-08。
+
+先从一个 skill 开始：把 Markdown 指令文件放进一个小型插件包。
+[hello-codewhale 示例](../examples/plugins/hello-codewhale/plugin.json)
+只有两个文件，不声明服务器或 hook，也不要求调用工具。
+本指南带你从源文件开始，完成审查、启用和调用。
+
+## 1. 创建插件包
+
+直接使用仓库中的示例，或在已安装插件目录之外创建以下目录：
+
+```text
+hello-codewhale/
+├── plugin.json
+└── skills/
+    └── hello/
+        └── SKILL.md
+```
+
+`plugin.json`：
+
+```json
+{
+  "$schema": "https://agent-plugins.org/schemas/plugin.json",
+  "name": "hello-codewhale",
+  "version": "0.1.0",
+  "description": "A minimal, explicitly invoked greeting skill."
+}
+```
+
+`skills/hello/SKILL.md`：
+
+```markdown
+---
+name: hello
+description: Greet the user when they explicitly try the hello-codewhale example.
+invocation: explicit-only
+---
+
+Respond with one short greeting in the user's language. Include the exact text
+`hello-codewhale:hello` so they can identify the example they invoked.
+
+Use only the conversation. Do not call tools, run commands, read or write files,
+or contact external services.
+```
+
+这里保留与仓库一致的英文示例；指令要求用用户的语言打招呼，并包含
+`hello-codewhale:hello`，同时不调用工具、不运行命令、不读写文件、不联系外部服务。
+Codewhale 会自动发现 `skills/`。`explicit-only` 表示此示例不进入模型的自动
+skill 目录，而是由你按名称加载。调用元数据见
+[Skills](../SKILLS.md#invocation-and-alias-metadata)，清单格式以
+[插件包契约](../PLUGIN_BUNDLES.md#manifest)为准。
+新原生插件使用 `plugin.json` 即可，无需再写另一份清单。
+
+## 2. 安装、检查并信任
+
+在仓库根目录启动 Codewhale，然后在 **Codewhale 会话内**逐条输入：
+
+```text
+/plugin install ./docs/examples/plugins/hello-codewhale
+/plugin validate hello-codewhale
+/plugin show hello-codewhale
+```
+
+如果使用自己的插件包，把安装路径替换为对应目录。安装会将插件复制到
+`~/.codewhale/plugins/hello-codewhale/`，初始状态为未启用、未信任。
+审查已安装的源文件、skill 清单和权限。此示例应只声明 Skills，
+没有 MCP 服务器、hook 或申请访问的网络主机。
+
+安装审查会打印一条包含两个完整哈希的命令：
+
+```text
+/plugin trust hello-codewhale <full-content-sha256>.<full-capability-sha256>
+```
+
+审查后执行实际打印的完整命令；上面的尖括号内容只是占位符。
+需要重新查看审查内容时，输入不带令牌的 `/plugin trust hello-codewhale`。
+信任操作记录已审查的内容哈希和能力哈希，并创建运行时快照，尚不会启用插件。
+
+```text
+/plugin enable hello-codewhale
+/skills hello-codewhale:
+/skills inspect
+```
+
+skill 的名称是 `hello-codewhale:hello`，即插件名加 skill 名。
+`/skills inspect` 会标明它来自已审查的插件快照。
+
+## 3. 调用并停用
+
+```text
+/skill hello-codewhale:hello
+```
+
+Codewhale 确认激活后，再发送普通消息 `请打个招呼。`。
+回复应是一句简短问候，并包含 `hello-codewhale:hello`。
+示例只提供指令；回复仍使用你选择的模型及其正常供应商连接。
+本地安装、审查和激活步骤本身不需要调用模型。
+
+```text
+/plugin disable hello-codewhale
+```
+
+停用会移除插件提供的功能，但保留信任记录。之后执行
+`/skill hello-codewhale:hello` 不应再激活该 skill。
+只要已审查的哈希仍然匹配，就可以在需要时重新启用。
+
+## 4. 修改并重新审查
+
+已安装的插件是副本。修改示例的原始源文件不会更新该副本。
+要尝试修改后的本地源文件，先停用并卸载已安装的示例，再重新安装源目录：
+
+```text
+/plugin disable hello-codewhale
+/plugin uninstall hello-codewhale
+/plugin install ./docs/examples/plugins/hello-codewhale
+/plugin validate hello-codewhale
+```
+
+卸载只删除已安装的副本，保留原始示例源文件。审查新的令牌，确认信任后再启用。
+从远程来源安装的插件使用 `/plugin update <name>`；详情见
+[插件安装指南](../PLUGINS.md#update-and-uninstall)。
+
+直接修改已发现插件目录内的文件后，使用 `/plugin reload` 刷新注册表。
+即使版本号没变，内容变化也会使旧信任记录失效。重新加载不会授予信任。
+要主动撤销信任，使用 `/plugin revoke <name>`。
+
+## 只添加需要的组件
+
+所有组件都使用同一套插件审查流程和现有 Codewhale 运行时：
+
+| 组件 | 编写方式 |
+| --- | --- |
+| Skills | `skills/<name>/SKILL.md`；参见[指令与调用契约](../SKILLS.md)。 |
+| MCP | 与清单同级的 `mcp.json`；参见[插件传输与凭据规则](../PLUGIN_BUNDLES.md#validation-both-formats)。 |
+| Commands | Markdown 命令文件；参见[命令元数据](../architecture/command-dispatch.md#user-commands)。 |
+| Agent profiles | Fleet TOML 配置文件；参见[Fleet 编写指南](../FLEET.md#authoring-agent-profiles-fleet-setup)。 |
+| Hooks | `HooksConfig` TOML 文件；参见[事件与进程行为](../HOOKS.md)。 |
+
+Commands、Agents 和 Hooks 的路径声明放在 `plugin.json` 的
+`extensions["net.codewhale"]` 中，详见
+[插件组件契约](../PLUGIN_BUNDLES.md#active-and-inactive-component-surfaces)。
+不要把 MCP 服务器字段或任意运行时入口放在清单根级。
+LSP 和原生扩展可以列入清单，但目前没有可执行的插件适配器。
+
+插件信任**不是操作系统沙箱**。本地 MCP 服务器或 hook 可以启动进程；
+启用前需审查其代码和权限。Skills 不授予权限：仓库指令、权限规则、沙箱策略
+和工具审批仍然适用。不要在插件包或命令参数中保存凭据。
+MCP 使用[插件验证契约](../PLUGIN_BUNDLES.md#validation-both-formats)规定的、
+经过审查的环境变量引用；添加 hook 前，请阅读独立的
+[hook 环境契约](../HOOKS.md#the-hook-process-environment)。
+
+## 转换现有插件
+
+[`scripts/convert-plugin.py`](../../scripts/convert-plugin.py) 将明确选定的远程 MCP
+声明和可移植 Skills 转换为原生插件包。需要 Python 3.10+ 和 PyYAML 6+；
+如果缺少，请单独安装。转换器不会安装依赖、扫描现有应用配置或凭据、
+发送网络请求，也不会执行源代码。
+
+### OpenCode
+
+将以下纯 JSON 保存为 `opencode-mcp.json`：
+
+```json
+{
+  "mcp": {
+    "docs": {
+      "type": "remote",
+      "url": "https://example.invalid/mcp",
+      "oauth": false,
+      "enabled": false
+    }
+  }
+}
+```
+
+在 Codewhale 仓库根目录的 shell 中运行：
+
+```sh
+python3 scripts/convert-plugin.py --format opencode-v1 \
+  --config ./opencode-mcp.json --name migrated-tools --output ./migrated-opencode
+```
+
+如果数据采用 `mcp.servers.<name>` 结构，请选择 `--format opencode-v2`；
+该格式的服务器开关是 `disabled`，不是 `enabled`。根据数据选择格式，
+不要依据文件名或上游分支名推断版本。两种格式都要求明确设置 `oauth: false`。
+远程 MCP 输出**仅使用 Streamable HTTP**，不会复现 OpenCode 回退到旧版 SSE 的行为。
+对于仅支持 SSE 的端点，请手工编写包含 `type: "sse"` 的原生 `mcp.json`，
+并使用相同的审查流程。
+
+选定 MCP 服务器时，配置中若包含 `tools`、`permission`/`permissions`、
+`agent`/`agents`、旧版 `mode` 或 `default_agent`，转换将被拒绝。
+这些设置可能在服务器开关之外进一步限制工具访问。请先在 Codewhale 中手工保留
+这些限制，再提供只含 MCP 声明的输入；直接删除这些设置可能扩大访问权限。
+
+转换器不接受 JSONC 注释或末尾多余逗号；请提供只含待移植声明的纯 JSON 副本。
+
+### DeepSeek Harness（DSH）
+
+将以下静态 Cordis 条目列表保存为 `dsh-mcp.yml`：
+
+```yaml
+- name: '@deepseek-ai/dsh-mcp-client'
+  disabled: true
+  config:
+    serverName: docs
+    transport: streamable-http
+    url: https://example.invalid/mcp
+```
+
+```sh
+python3 scripts/convert-plugin.py --format dsh \
+  --config ./dsh-mcp.yml --name migrated-dsh --output ./migrated-dsh
+```
+
+DSH 输入也可以使用 JSON，但必须是普通条目列表，不能是完整 profile 或
+patch 组合。每个条目的 `name` 都必须为 `@deepseek-ai/dsh-mcp-client`。
+
+### 审查转换结果
+
+两个示例都保留服务器的停用状态，并使用占位端点。准备连接时，先替换源文件中的
+端点并修改启用开关，再重新转换。输出目录必须尚不存在，且其父目录已存在。
+已有输出会被拒绝覆盖；输入被拒绝时不会留下输出插件包。
+
+添加 `--skill ./my-skill` 可选择包含 `SKILL.md` 的目录，也可以用
+`--skill ./my-skill.md` 选择单个文件；重复该选项可选择多个 skill。
+仅转换 Skills 时可以省略 `--config`。Skills 的 frontmatter 必须包含
+`name` 和 `description`。`disable-model-invocation: true` 会转换为原生的
+`invocation: explicit-only`。说明性字段 `license`、`compatibility` 和
+`metadata` 会保存在伴随数据文件 `SOURCE_SKILL_METADATA.json` 中。
+所选 skill 目录中的其他文件会作为数据复制；加载 skill 前需审查这些文件及其指令。
+
+只有完全符合 `{env:MCP_TOKEN}` 形式的 OpenCode 请求头引用会转换为原生
+`env_headers`；转换器不会读取变量值。字面量请求头、DSH 请求头表达式以及
+URL 中的文件或环境变量替换都会被拒绝。配置的超时值以毫秒表示，
+必须是 `1000` 到 `3600000` 之间的整秒值。未指定的超时使用 Codewhale 的默认值。
+
+可执行插件和 hooks、stdio 服务器、自动 OAuth、JavaScript、YAML 别名或标签、
+`__jsExpr`，以及不支持的 skill 运行时字段（包括 `user-invocable: false`）
+需要手工移植。转换不会复现其他客户端的运行时，也不会绕过 Codewhale 的凭据
+和沙箱规则。
+
+阅读生成的 `CONVERSION.md`、`plugin.json`、`mcp.json`（如有）和所有选定的
+skill 文件。然后使用 `/plugin install ./migrated-opencode`（或 DSH 输出路径）、
+`/plugin validate <name>`，并按前文相同的哈希绑定流程审查、信任和启用。
+转换本身既不证明连接可用，也不证明运行时兼容；输出尚未安装、信任或启用。
+
+源码核查日期：2026-09-08。依据 OpenCode `d6855b6b47` 的
+[v1 MCP 文档](https://github.com/anomalyco/opencode/blob/d6855b6b47a8433462ac6aeeba882ccf734cb7f1/packages/web/src/content/docs/mcp-servers.mdx)
+和 [v2 MCP schema](https://github.com/anomalyco/opencode/blob/d6855b6b47a8433462ac6aeeba882ccf734cb7f1/packages/core/src/config/mcp.ts)，
+以及 DSH `c389f96bf3` 的 [MCP 客户端参考](https://github.com/deepseek-ai/deepseek-harness/blob/c389f96bf3a9b6807cb71ed6bdad5849be0df6d8/packages/mcp/mcp-client/README.md)。
+上游支持的功能多于此转换器明确支持的范围。

 子代理默认继承父代理的工具注册表，其中包括 `agent` 本身：子代理用 `with_full_agent_surface_options`（`crates/tui/src/tools/subagent/mod.rs:12164`）构建，因此它们可以递归。只有当深度预算耗尽时，`agent` 才会从子代理的目录中过滤掉——`can_spawn_child = !runtime.would_exceed_depth()`（`mod.rs:12145`），在 `mod.rs:12324` 和 `:12469` 强制执行。默认深度为 3（`DEFAULT_SPAWN_DEPTH`，`crates/config/src/lib.rs:1671`）时，子代理可以生成孙代理。已移除的 `agent_open`/`agent_eval`/`agent_close` 生命周期工具已从每个注册表中消失，父代理和子代理皆然。
 
-`agent` 启动 detached 后台工作：取消父代理的回合会停止父代理的等待路径，但不会杀死已经打开的 child 运行。
+`agent` 子代理默认归当前父回合所有；结束或取消父回合会停驻前台后代。只有显式 `detached=true` 才使用独立取消令牌启动后台工作。
 
 本文档涵盖角色分类和当前兼容性控制。活动的编排面是 `agent`；参见 `crates/tui/src/prompts/text.rs`（`AGENT_MODE`）中的子代理指南以及行内工具描述。

 角色的默认值就是该角色*想要*的姿态，而父代理的有效姿态永远是天花板（子代理绝不会扩得比父代理更宽）。只读角色按意图扣留**工作区写入**；默认不拿走任何其他东西——每个角色都保留网络读取，`custom` 继承父代理的写入/网络/shell 姿态，并且只被它的显式工具列表或发起调用收窄。被聚焦的 worker 的头部会依据运行时自身的权限快照声明有效姿态（`scout · read-only · network · read-only shell`）。
 
-**委派移动的是工作，绝不是权限**（#5426 的遏制答案）。只读角色委派给可写角色（scout → builder）是*工作容量*受支持的逃生舱——子代理自带其模型、路由和步骤预算——但子代理的权限被钳制在委派父代理的实时姿态上，而不是操作者的姿态上：scout 的 builder 子代理以只读落地，raw shell 和可变工具被拒绝，规范的 `Bash` 对它也被拒绝（只有有界检查角色保留分类的只读 shell）。因此通过委派来获得 shell 在机制上是无用的——scout 自带的受限 shell（`git -C … log`、`find … | head`、`npm view …`，分类器门控）是只读父代理唯一的 shell 路径。只读通过任何委派链都是传递的：钳制（`fleet/exact.rs` 中的 `ChildAuthority::clamp`）把每个字段与更窄的一侧求交，拒绝列表的并集意味着后代永远无法去掉祖先的限制，而 `inherit_disallowed_tools: false` 无法去掉姿态拒绝（`is_posture_denial`）。这一点由 `crates/tui/src/fleet/exact.rs` 测试中的 `a_read_only_parents_delegation_never_widens_authority` 钉死。

 会话的**权限姿态**在每个子代理内部的应用方式与父代理回合完全一致：在 Auto-Review 下，同一个确定性底线和一次性模型守护者决定 worker 的被扣留调用（绝不是提示词；守护者不可用时拒绝，fail closed）；在 Ask 下，角色无法委派的被扣留调用会作为审批提示在父代理的 UI 中弹出，worker 可见地等待（`waiting for user`），或者在无法提示的主机上带着原因被拒绝；Full Access 仍然在不可绕过的安全底线上 fail closed。每一次没有人被提示的决策都是该 worker 转录中的一行备注（聚焦时可见）和一条审计日志记录。参见 `docs/MODES.md`。

+面向模型的 `agent` 工具 schema 包含生命周期、作用域和每个任务的路由控制（#5915、#5955）：

 外加按 action 区分的 `dependentSchemas` 树（`start` 需要 `prompt`；`message`/`followup` 需要目标和 `message`；`peek`/`interrupt`/`cancel` 需要目标）。schema 变更是钉死的提示词前缀的一部分，所以升级会在每个会话中重新填充一次 provider KV 前缀（docs/CACHE.md；在 v0.9.9 边界接受）。
 
+`agent(action="roster")` 使用与执行相同的解析器，列出内置角色实际使用的 provider、模型、思维层级、已知上下文限制和能力来源。每个任务的 `model` 优先于 `model_strength`，然后采用角色默认值和会话路由。请求其他 provider 的模型会在接受任务前被拒绝；角色权限上限保持不变。
+
+`profiles` 行显示现有已选 Fleet，或受信任配置、个人、工作区和插件层中的保存成员，并提供有界身份及相同的路由/费用证据。`profile="bug-hunter"` 使用该成员的指令、角色、provider/模型固定选择和深度上限。冲突的类型或模型请求会被拒绝；显式 `thinking` 可以覆盖保存的层级。缺失 provider、撤销的插件权限或禁用的项目配置会在接受子任务前失败。发现操作不会创建配置或自动添加模型。保存配置继续使用现有子任务生命周期，本身不代表持续 Bot 会话或 Computer 租约。
+
+费用类别仅描述当前未缓存文本输入和输出的费率，不代表未来任务的总费用。缺少费率或依赖路由的价格保持未知；订阅和本地路由标记为非按金额计费。查询不会向 provider 发送请求，可达性标记为未验证。
+
 **解析接受但未公布（兼容）。** 以下输入已从公布的 schema 中移除，但仍保持解析接受并按原样生效，因此已保存的转录、ACP/MCP 客户端和 Fleet 配置照旧重放——`token_budget` 已经遵循的正是同一个契约：
 
 - 预算：`max_steps`、`wall_time_secs`、`max_depth`（参见[子代理预算](#子代理预算步数墙钟时间)了解默认值现在来自何处）
-- 路由：`model`、`model_strength`、`thinking`（`profile` 钉死路由和思维层级；没有它时子代理继承操作者模型）
 - workspace/隔离：`workspace_policy`、`write_authority`、`fork_context`、`cwd`、`worktree_path`、`worktree_branch`、`worktree_base`
 - 发起契约：`deliberate`、`dependencies`、`acceptance`、`expected_artifact`、`exact_files`、`coordination_contracts`
 - 生命周期附加：`timeout_secs`（wait）、`reason`（interrupt）、`include_archived`（status）以及 `token_budget`

+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
