docs: expand v2.2.0 release notes + README for full 2.2 scope

The pre-existing release notes and README "What's New in 2.2" block
only covered the original Project Templates feature. This expands
both to reflect everything that's actually shipping in 2.2:

- Template Configuration (schemaVersion 2): typed schema, 7 field
  types, Keychain-backed secrets, configure step in install flow,
  post-install Configuration editor, model recommendations.
- Template Catalog: gh-pages site with live dashboard previews,
  stdlib-only Python validator mirroring Swift invariants, PR CI
  gate, install-URL hosting from raw main.
- Example template `awizemann/site-status-checker` exercising every
  v2.2 surface — config form, cron, Site tab webview, dashboard
  updates.
- Site tab — a webview widget in any dashboard exposes a second
  tab next to Dashboard, rendering a live URL.
- UX clarifications: Remove from List (keep files) vs. Uninstall
  Template (remove installed files), preserved-files banner on
  uninstall success, Run Now no longer blocks on long agent runs.
- Install-time {{PROJECT_DIR}} / {{TEMPLATE_ID}} / {{TEMPLATE_SLUG}}
  token substitution in cron prompts.

Release-notes link + wiki link surfaced at the bottom of the README
block so readers have a jump to full details.

+## What's in this PR
+
+- [ ] New template: `templates/<your-handle>/<your-template-name>/`
+- [ ] Update to existing template: `templates/<author>/<name>/` (which one and why)
+
+## One-line pitch
+
+_What does this template do for its installers? Two sentences max._
+
+## Checklist
+
+- [ ] I wrote this template, or have the author's explicit permission to submit it.
+- [ ] `AGENTS.md` is present and tells any cross-agent what the project does and how to run it.
+- [ ] `README.md` includes install, customize, and uninstall instructions.
+- [ ] The bundle's `template.json` `contents` claim matches what's actually in the zip.
+- [ ] Cron jobs (if any) ship paused and use self-contained prompts.
+- [ ] No secrets in any file (API keys, tokens, hostnames, IPs, credentials).
+- [ ] No writes to `config.yaml`, `auth.json`, or credential paths — v1 installer will refuse.
+- [ ] `python3 tools/build-catalog.py --check` passes locally.
+- [ ] I installed + uninstalled this template on my machine and verified the `AGENTS.md` contract works end-to-end.
+- [ ] I did **not** edit `templates/catalog.json` — the maintainer regenerates it post-merge.

+## Testing notes
+
+_What did you run, what did you see? Paste the log output of the cron job
+firing once, or the chat transcript of asking the agent to do the main
+thing. Reviewers don't have your machine — show, don't tell._

+## Releases
+
+Shipped via a single local script. **Never run manual `xcodebuild archive` / `notarytool` / `gh release create` steps — use the script so nothing is skipped or misordered.**
+
+```bash
+./scripts/release.sh <version>           # full release: notarize → appcast → gh-pages → tag
+./scripts/release.sh <version> --draft   # draft: everything builds + notarizes, but appcast/tag are skipped
+```
+
+The script bumps version, archives Universal (arm64 + x86_64) + ARM64-only variants, signs with Developer ID, notarizes via `xcrun notarytool` (keychain profile `scarf-notary`), staples, EdDSA-signs the appcast entry with Sparkle's key, pushes the appcast to `gh-pages`, and creates a GitHub release with both zips attached. Draft mode stops after the release is uploaded so the current version stays "latest" until explicitly promoted.
+
+**Release notes convention:** write them to `releases/v<version>/RELEASE_NOTES.md` BEFORE running the script — it's auto-included in the version-bump commit and used as the GitHub release body. If absent, a placeholder is used.
+
+**Canonical prompts (any of these trigger the flow):**
+- "Release v1.6.2" — full release
+- "Release v1.6.2 as draft" — draft mode
+- "Prepare v1.6.2 release notes from recent commits, then release" — generate notes first, then run
+
+**Prerequisites (one-time, already set up on Alan's machine):** Developer ID Application cert in login Keychain (team `3Q6X2L86C4`), notarytool keychain profile `scarf-notary`, Sparkle EdDSA private key in Keychain item `https://sparkle-project.org`, `gh-pages` branch + GitHub Pages enabled. See the header of [scripts/release.sh](scripts/release.sh) and the Releases section in [README.md](README.md) for details.
+
+## Wiki
+
+Public documentation lives in the GitHub wiki at https://github.com/awizemann/scarf/wiki. The wiki is a separate git repo cloned to `.wiki-worktree/` in the repo root (gitignored, sibling to `.gh-pages-worktree/`). Internal dev notes stay in `scarf/docs/`; the wiki is for public-facing reference.
+
+**Update the wiki when:**
+- A new feature module is added under `scarf/scarf/scarf/Features/` → extend the relevant User Guide page.
+- A new core service is added under `Core/Services/` → extend `Core-Services.md`.
+- Architecture changes (AppCoordinator, transport, MVVM-F rule, sandbox) → `Architecture-Overview.md` + the specific sub-page.
+- Hermes version bumps in this file → `Hermes-Version-Compatibility.md`.
+- `scripts/release.sh` completes a full (non-draft) release → bump latest-version on `Home.md` + append to `Release-Notes-Index.md`.
+- Keyboard shortcut or sidebar section changes → `Keyboard-Shortcuts.md` / `Sidebar-and-Navigation.md`.
+
+**Skip for:** bug fixes with no user-observable change, pure refactors, typos, test-only changes, internal cleanups.
+
+```bash
+./scripts/wiki.sh pull                         # always first
+# edit .wiki-worktree/*.md with normal tools
+./scripts/wiki.sh commit "docs: describe X"   # runs secret-scan
+./scripts/wiki.sh push                         # runs secret-scan again, then push
+```
+
+**Never** commit API keys, tokens, `.env` files, private keys, or real hostnames/IPs to the wiki. The script's two-pass secret-scan blocks common token patterns and a user-maintained blocklist at `scripts/wiki-blocklist.txt` (gitignored). Do not bypass without explicit approval. Full workflow on the wiki itself at `.wiki-worktree/Wiki-Maintenance.md`.
+
 ## Hermes Version
 
 Targets Hermes v0.9.0 (v2026.4.13). Log lines may carry an optional `[session_id]` tag between the level and logger name — `HermesLogService.parseLine` treats the session tag as an optional capture group, so older untagged lines still parse.
+
+## Project Templates
+
+Scarf ships a `.scarftemplate` format (v1 as of 2.2.0) for sharing pre-packaged projects across users and machines. A bundle is a zip containing:
+
+- `template.json` — manifest (id, name, version, `contents` claim)
+- `README.md` — shown in the install preview sheet
+- `AGENTS.md` — required; the [Linux Foundation cross-agent instructions standard](https://agents.md/) — every template is agent-portable out of the box
+- `dashboard.json` — copied to `<project>/.scarf/dashboard.json`
+- `instructions/…` — optional per-agent shims (`CLAUDE.md`, `GEMINI.md`, `.cursorrules`, `.github/copilot-instructions.md`)
+- `skills/<name>/…` — optional; installed to `~/.hermes/skills/templates/<slug>/` (namespaced so uninstall is `rm -rf` on one folder)
+- `cron/jobs.json` — optional; registered via `hermes cron create` with a `[tmpl:<id>] …` name prefix and immediately paused
+- `memory/append.md` — optional; appended to `~/.hermes/memories/MEMORY.md` between `<!-- scarf-template:<id>:begin/end -->` markers
+
+Key services: [ProjectTemplateService.swift](scarf/scarf/Core/Services/ProjectTemplateService.swift) (inspect + validate + plan), [ProjectTemplateInstaller.swift](scarf/scarf/Core/Services/ProjectTemplateInstaller.swift) (execute a plan), [ProjectTemplateExporter.swift](scarf/scarf/Core/Services/ProjectTemplateExporter.swift) (build a bundle from a project), [ProjectTemplateUninstaller.swift](scarf/scarf/Core/Services/ProjectTemplateUninstaller.swift) (reverse an install using the lock file). UI in [Features/Templates/](scarf/scarf/Features/Templates/). The `scarf://install?url=<https URL>` deep link + `file://` URLs for `.scarftemplate` files are handled by [TemplateURLRouter.swift](scarf/scarf/Core/Services/TemplateURLRouter.swift) and `onOpenURL` in `scarfApp.swift`. A `<project>/.scarf/template.lock.json` uninstall manifest is written after every install and drives the uninstall flow.
+
+**Uninstall semantics:** driven by the lock file. Only files listed in `lock.projectFiles` are removed from the project dir; user-added files (e.g. a `sites.txt` created on first run) are preserved. If every file in the dir was installed by the template, the dir is removed too; otherwise the dir stays with just the user's files. Skills namespace is always removed wholesale (it's isolated). Cron jobs are removed via `hermes cron remove <id>` after resolving each lock-recorded name. Memory block is stripped between the `begin`/`end` markers, leaving the rest of MEMORY.md intact. No "undo" — uninstall is destructive; to re-install, run the install flow again. Uninstall UI lives on the project-list context menu and the dashboard header (only shown when the selected project has a lock file).
+
+**Never** let a template write to `config.yaml`, `auth.json`, sessions, or any credential path — the v1 installer refuses. If you extend the format, treat the preview sheet as load-bearing: the user's only trust boundary is that the sheet is honest about everything that's about to be written.
+
+### Template configuration (v2.3, schemaVersion 2)
+
+Templates can declare a typed configuration schema in `template.json`'s new `config` block. The installer renders a **Configure** step between the parent-directory pick and the preview sheet; values land at `<project>/.scarf/config.json` (non-secret) and in the login Keychain (secret). A post-install **Configuration** button on the dashboard header (shown when `<project>/.scarf/manifest.json` exists) opens the same form pre-filled for editing.
+
+Manifest shape:
+
+```json
+{
+  "schemaVersion": 2,
+  "contents": { "dashboard": true, "agentsMd": true, "config": 2 },
+  "config": {
+    "schema": [
+      {"key": "site_url", "type": "string", "label": "Site URL", "required": true},
+      {"key": "api_token", "type": "secret", "label": "API Token", "required": true}
+    ],
+    "modelRecommendation": {
+      "preferred": "claude-sonnet-4.5",
+      "rationale": "Tool-heavy workload — reasoning helps."
+    }
+  }
+}
+```
+
+Supported field types: `string`, `text`, `number`, `bool`, `enum` (with `options: [{value, label}]`), `list` (itemType `"string"` only in v1), `secret`. Type-specific constraints (`pattern`, `min`/`max`, `minLength`/`maxLength`, `minItems`/`maxItems`) are optional. `secret` fields **must not** declare a `default` — the validator refuses.
+
+Key services: [TemplateConfig.swift](scarf/scarf/Core/Models/TemplateConfig.swift) (schema + value models + Keychain ref helpers), [ProjectConfigKeychain.swift](scarf/scarf/Core/Services/ProjectConfigKeychain.swift) (thin `SecItemAdd`/`Copy`/`Delete` wrapper; the only Keychain user in Scarf today), [ProjectConfigService.swift](scarf/scarf/Core/Services/ProjectConfigService.swift) (load/save config.json, resolve secrets, cache manifest, validate schema + values). UI in [Features/Templates/ViewModels/TemplateConfigViewModel.swift](scarf/scarf/Features/Templates/ViewModels/TemplateConfigViewModel.swift) + [Features/Templates/Views/TemplateConfigSheet.swift](scarf/scarf/Features/Templates/Views/TemplateConfigSheet.swift).
+
+**Secret storage.** Keychain service name is `com.scarf.template.<slug>`, account is `<fieldKey>:<project-path-hash-short>`. The path-hash suffix means two installs of the same template in different dirs don't collide on Keychain entries. Values in `config.json` are `"keychain://service/account"` URIs — never plaintext. The bytes hit the Keychain only on form commit, so cancelling never leaves orphan entries.
+
+**Uninstall.** `TemplateLock` v2 gains `config_keychain_items` and `config_fields` arrays. The uninstaller iterates each URI through `SecItemDelete` before removing the lock file. Absent items (user hand-cleaned) are no-ops.
+
+**Exporter.** Carries the *schema* from `<project>/.scarf/manifest.json` through into exported bundles, never values. Exporting never leaks anyone's secrets. `schemaVersion` bumps to 2 only when a schema is forwarded; schema-less exports stay at 1.
+
+**Catalog site.** [tools/build-catalog.py](tools/build-catalog.py) mirrors the Swift schema validator. Each v2 template's `template.json` is copied into `.gh-pages-worktree/templates/<slug>/manifest.json` and the site's `widgets.js` calls `ScarfWidgets.renderConfigSchema` to display the schema on the detail page (display-only — the form lives in-app).
+
+**Schema is Swift-primary.** If `TemplateConfigField.FieldType` gains a new case, update in order: `TemplateConfig.swift` (model + validation), `tools/build-catalog.py` (`SUPPORTED_CONFIG_FIELD_TYPES` + type-specific rules), `widgets.js` (`summariseConstraint`), `TemplateConfigSheet.swift` (new control subview), tests on both sides. Schema drift between validator + installer is the kind of bug users only notice after shipping.
+
+## Template Catalog
+
+Shipped community templates live at `templates/<author>/<name>/` (one level down — `templates/CONTRIBUTING.md` explains the submission flow for authors). The catalog site is generated from this directory and served at `awizemann.github.io/scarf/templates/` alongside the Sparkle appcast — the two coexist on the `gh-pages` branch but touch completely disjoint paths.
+
+Pipeline:
+
+- **Validator + regenerator:** [tools/build-catalog.py](tools/build-catalog.py) is stdlib-only Python (3.9+). It walks `templates/*/*/`, validates every `.scarftemplate` against its manifest claim (mirrors the Swift `ProjectTemplateService.verifyClaims` invariants), enforces a 5 MB bundle-size cap, scans for high-confidence secret patterns, checks `staging/` matches the built bundle byte-for-byte, and emits `templates/catalog.json`. Tested by [tools/test_build_catalog.py](tools/test_build_catalog.py) — 16 tests covering every validation path.
+- **Wrapper:** [scripts/catalog.sh](scripts/catalog.sh) mirrors the `scripts/wiki.sh` shape with `check / build / preview / serve / publish` subcommands. `publish` runs a second-pass secret-scan against the rendered site before committing + pushing `gh-pages`.
+- **Site source:** `site/index.html.tmpl` + `site/template.html.tmpl` are `{{TOKEN}}`-substitution templates. `site/widgets.js` (~300 lines of vanilla JS) is the dogfood — renders a `ProjectDashboard` JSON into HTML using the same widget vocabulary the Swift app uses, so each template's detail page shows a live preview of its post-install dashboard.
+- **Install-URL hosting:** raw-served from `main` at `https://raw.githubusercontent.com/awizemann/scarf/main/templates/<author>/<name>/<name>.scarftemplate`. No per-template Releases ceremony.
+- **CI gate:** [.github/workflows/validate-template-pr.yml](.github/workflows/validate-template-pr.yml) runs the Python validator + its own test suite on every PR that touches `templates/`, the validator, or its tests. Failures post a comment on the PR with the last 3 KB of the validator log.
+
+Maintainer workflow on merge to main:
+
+```bash
+./scripts/catalog.sh build       # regenerate templates/catalog.json + .gh-pages-worktree/templates/
+./scripts/catalog.sh publish     # secret-scan rendered output + commit + push gh-pages
+```
+
+Same cadence as `scripts/release.sh` (manual, auditable, no auto-deploy). Runs stay isolated: release.sh only touches `appcast.xml` on gh-pages; catalog.sh only touches `templates/` on gh-pages. Never push catalog output on a release cadence or vice versa.
+
+**Schema is Swift-primary.** When `ProjectDashboardWidget.type` gains a new case or `ProjectTemplateManifest` adds a field, update Swift first, then mirror into `tools/build-catalog.py` (`SUPPORTED_WIDGET_TYPES`, `_validate_manifest`, `_validate_contents_claim`) so the web validator stays honest. The Python test suite's real-bundle test catches drift on the example template but not on the full widget vocabulary — add a synthetic fixture to `test_build_catalog.py` for any new widget type.

+## Documentation
+
+Public docs live in the [GitHub wiki](https://github.com/awizemann/scarf/wiki). Small fixes (typos, clarifications) can be made via the "Edit" button on any wiki page — you need push access to the main repo. For larger changes, clone the wiki locally (`git clone git@github.com:awizemann/scarf.wiki.git`) or open an issue describing the proposed change.
+
+## Adding a Language
+
+Scarf ships with English + Simplified Chinese, German, French, Spanish, Japanese, and Brazilian Portuguese. To add another locale (or improve an existing one):
+
+1. **Fork** the repo and create a branch.
+2. **Add the locale to `knownRegions`** in `scarf/scarf.xcodeproj/project.pbxproj` — follow the existing list (e.g. add `it` after `"pt-BR"`).
+3. **Drop a new JSON file at `tools/translations/<locale>.json`** — copy an existing one (say `tools/translations/es.json`) as a starting point. Each entry maps the English source string to your translation. Keys you omit fall back to English at runtime — do that for proper nouns (Scarf, Hermes, Anthropic, OAuth, SSH, …) and for anything technical that shouldn't translate.
+4. **Preserve format specifiers exactly**: `%@`, `%lld`, `%d`, positional `%1$@` / `%2$lld`, etc. If word order needs to change in your language, use positional forms (`%1$@ … %2$@`).
+5. **Add your locale to `tools/merge-translations.py`'s `LOCALES` list** and run `python3 tools/merge-translations.py` — this writes your translations into `scarf/scarf/Localizable.xcstrings`.
+6. **Translate `scarf/scarf/InfoPlist.xcstrings`** (the macOS microphone-permission prompt) for your locale. Add a new `stringUnit` under `localizations`.
+7. **Build** (`xcodebuild -project scarf/scarf.xcodeproj -scheme scarf build`) and **sanity-check in Xcode**: Scheme → Run → App Language → your locale. Walk the main views (Dashboard, Chat, Settings) and look for clipping or obvious leaks.
+8. **Open a PR** including the new JSON file, the updated catalog, and the pbxproj / script changes. Mention which routes you spot-checked.
+
+AI translation is fine for the first pass — it's how the initial six locales landed. Native-speaker review improves quality and is always welcome, either as a follow-up PR or as review comments on the initial one.
+
+See [scarf/docs/I18N.md](scarf/docs/I18N.md) for deeper context on the String Catalog setup and which strings are intentionally kept verbatim.

+## What's New in 2.2
+
+- **Project Templates** — Scarf projects can now travel. Package a project's dashboard, agent instructions, skills, cron jobs, and a typed configuration schema into a `.scarftemplate` bundle, hand it to anyone, and they install it in one click. Every bundle ships with a cross-agent `AGENTS.md` ([agents.md](https://agents.md/) standard) so the instructions work in Claude Code, Cursor, Codex, Aider, and the 20+ other agents that read it natively. Browser-based one-click install via `scarf://install?url=…` deep links. Export / Install from File / Install from URL live under the new **Templates** menu in the Projects toolbar.
+- **Typed configuration with Keychain-backed secrets** — Templates declare a schema with seven field types (`string`, `text`, `number`, `bool`, `enum`, `list`, `secret`). A **Configure** step in the install flow renders the form, routes secrets to the macOS Keychain, and drops non-secret values into `<project>/.scarf/config.json`. A slider icon in the dashboard header opens the same form post-install for edits — rotate a token, change a site, toggle a feature, and the next cron run picks it up.
+- **Public template catalog** — [awizemann.github.io/scarf/templates/](https://awizemann.github.io/scarf/templates/) is a static catalog site generated from `templates/<author>/<name>/` in this repo. Each template has a detail page with a live dashboard preview, the schema rendered with constraint summaries, and a one-click install button. Community submissions go through a CI-enforced Python validator that mirrors the Swift-side invariants.
+- **Preview-before-apply** — Every install shows a preview sheet listing the exact project directory that will be created, every file inside it, every skill that will be namespaced, every cron job that will be registered (paused by default), every Keychain secret that will be written, and a live diff of any memory appendix. Markdown fields render inline. Nothing writes until you click Install.
+- **Site tab** — A dashboard with at least one `webview` widget gets a second tab next to Dashboard. The example `awizemann/site-status-checker` template uses this to render whatever URL you configured as your first watched site, updating on every cron run.
+- **Safe-by-design** — Skills install into `~/.hermes/skills/templates/<slug>/` so they never collide with your own. Cron jobs carry a `[tmpl:<id>]` tag and start paused. A `template.lock.json` records every file, cron job, Keychain ref, and memory block for one-click uninstall. Exports carry the configuration schema but never the user's values — safe on projects with live config. Templates **never** touch `config.yaml`, `auth.json`, sessions, or credentials.

+- **Seven languages** — Full UI translations for Simplified Chinese, German, French, Spanish, Japanese, and Brazilian Portuguese on top of English. Scarf respects the system language by default; override per-app via **System Settings → Language & Region → Apps → Scarf**. Contributor workflow for adding more locales is documented in [CONTRIBUTING.md → Adding a Language](CONTRIBUTING.md#adding-a-language).
+- **Locale-aware number formatting** — Currency, byte sizes, compact token counts (`15K`, `1.5M`), and day-of-week charts now follow the user's locale instead of POSIX / English defaults.
+- **Chat slash-command menu** — Type `/` in Rich Chat to browse every command the agent has advertised plus any user-defined `quick_commands:` from config.yaml. ↑/↓ to navigate, Tab/Enter to complete, Esc to dismiss.
+- **Chat polish** — Auto-scroll on send and on prompt completion, a non-blocking loading spinner during session reconnects, properly centered empty state, and the long-standing "session loads with whitespace" bug fixed (LazyVStack → VStack in the message list).

+
+## Multi-server, one window per server
+
+Scarf 2.0 is a multi-window app. Each window is bound to exactly one Hermes server — your local `~/.hermes/` is synthesized automatically, and you can add remotes via **File → Open Server…** → **Add Server** (host, user, port, optional identity file). Open a second window for a different server and the two run side-by-side with independent state.
+
+Remote Hermes is reached over system SSH — the same `~/.ssh/config`, ssh-agent, ProxyJump, and ControlMaster pooling your terminal uses. File I/O flows through `scp`/`sftp`; SQLite is served from atomic `sqlite3 .backup` snapshots cached under `~/Library/Caches/scarf/snapshots/<server-id>/`; chat (ACP) tunnels as `ssh -T host -- hermes acp` with JSON-RPC over stdio end-to-end. Everything in the feature list below works against remote identically to local.
+
+### Remote setup requirements
+
+The remote host must have:
+
+1. **SSH access** — key-based auth via your local ssh-agent. Scarf never prompts for passphrases; run `ssh-add` once in Terminal before connecting.
+2. **`sqlite3`** on the remote `$PATH` — needed for the atomic DB snapshots. Install on the remote with `apt install sqlite3` (Ubuntu/Debian), `yum install sqlite` (RHEL/Fedora), or `apk add sqlite` (Alpine).
+3. **`pgrep`** on the remote `$PATH` — used by the Dashboard "is Hermes running" check. Standard on every distro; install `procps` if missing.
+4. **`~/.hermes/` readable by the SSH user**. When Hermes runs as a separate user (systemd service, Docker container), the SSH user needs read access to `config.yaml` and `state.db`. Either (a) SSH as the Hermes user, (b) `chmod` Hermes's home to be group-readable and add your SSH user to that group, or (c) set the **Hermes data directory** field when adding the server to point at the right location (e.g. `/var/lib/hermes/.hermes`).
+
+### Troubleshooting remote connections
+
+If the connection pill is green but the Dashboard shows "Stopped", "unknown", or empty values, the SSH user can't read the Hermes state files. Open **Manage Servers → 🩺 Run Diagnostics** (or click the yellow "Can't read Hermes state" pill in the toolbar). The diagnostics sheet runs fourteen checks in one SSH session — connectivity, `sqlite3` presence, read access to `config.yaml` and `state.db`, the effective non-login `$PATH` — and tells you exactly which one fails and why, with remediation hints for each. Use the **Copy Full Report** button to paste the full output into a bug report.
+
+For the common "Hermes isn't at the default path" case (systemd services, Docker), **Test Connection** in the Add Server sheet now probes `/var/lib/hermes/.hermes`, `/opt/hermes/.hermes`, `/home/hermes/.hermes`, and `/root/.hermes` when it can't find `state.db` at `~/.hermes/`, and offers a one-click fill if it finds any of them.
+
 ## Features
 
+Scarf mirrors Hermes's surface area through a sidebar-based UI. Sections below map 1:1 to the app's sidebar.
+
+### Monitor
+
 - **Dashboard** — System health, token usage, cost tracking, recent sessions with live refresh
 - **Insights** — Usage analytics with token breakdown (including reasoning tokens), cost tracking, model/platform stats, top tools bar chart, activity heatmaps, notable sessions, and time period filtering (7/30/90 days or all time)
 - **Sessions Browser** — Full conversation history with message rendering, model reasoning/thinking display, tool call inspection, full-text search, rename, delete, and JSONL export. Subagent sessions are filtered from the main list and accessible via parent session drill-down
 - **Activity Feed** — Recent tool execution log with filtering by kind and session, detail inspector with pretty-printed arguments and tool output display
+
+### Interact
+
 - **Live Chat** — Two modes: **Rich Chat** streams responses in real-time via the Agent Client Protocol (ACP) with iMessage-style bubbles, markdown rendering, tool call visualization, thinking/reasoning display, permission request dialogs, and a one-click `/compress` focus sheet (when Hermes advertises the command); **Terminal** runs `hermes chat` with full ANSI color and Rich formatting via [SwiftTerm](https://github.com/migueldeicaza/SwiftTerm). Both modes support session persistence, resume/continue previous sessions, auto-reconnection with session recovery, and voice mode controls
 - **Memory Viewer/Editor** — View and edit Hermes's MEMORY.md and USER.md with live file-watcher refresh, external memory provider awareness (Honcho, Supermemory, etc.), and profile-scoped memory support with profile picker
-- **Skills Browser** — Browse and edit installed skills by category with file content viewer, file switcher, and required config warnings for skills that need specific settings
+- **Skills Browser** — Browse installed skills by category with file content viewer and required config warnings. **New in 1.6:** Browse the Skills Hub, search by registry (official, skills.sh, well-known, GitHub, ClawHub, LobeHub), install, check for updates, and uninstall — all from the app
-- **Tools Manager** — Enable/disable toolsets per platform (CLI, Telegram, Discord, Slack, WhatsApp, Signal, iMessage, Email, Home Assistant, Webhook, Matrix, Feishu, Mattermost) with toggle switches and segmented platform picker, MCP server status
+
+### Configure *(new in 1.6)*
+
+- **Platforms** — Native GUI setup for all 13 messaging platforms (Telegram, Discord, Slack, WhatsApp, Signal, Email, Matrix, Mattermost, Feishu, iMessage, Home Assistant, Webhook, CLI). Per-platform forms write credentials to `~/.hermes/.env` and behavior toggles to `~/.hermes/config.yaml`. WhatsApp and Signal pairing use an inline SwiftTerm terminal for QR scan and signal-cli daemon management
+- **Personalities** — List defined personalities, pick the active one, and edit `SOUL.md` inline with markdown preview
+- **Quick Commands** — Editor for custom `/command_name` shell shortcuts with dangerous-pattern detection (`rm -rf`, `mkfs`, etc.)
+- **Credential Pools** — Per-provider credential rotation with a fixed OAuth flow (URL extraction + browser open + code paste) and proper `--type api-key` handling. API keys never stored in UI state — only last-4 preview. Strategy picker (fill_first / round_robin / least_used / random)
+- **Plugins** — Install via Git URL or `owner/repo`, update, remove, enable/disable. Reads `~/.hermes/plugins/` directly for reliable state
+- **Webhooks** — Create, list, test-fire, and remove webhook subscriptions. Detects the "platform not enabled" state and links to gateway setup
+- **Profiles** — Switch between multiple isolated Hermes instances. Create, rename, delete, export (zip), import. Safe-switch warning reminds users to restart Scarf after activating a different profile
+
+### Manage
+
+- **Tools** — Enable/disable toolsets per platform with a connectivity-aware platform menu (green/orange/grey/red dots for connected/configured/offline/error). **Fixed in 1.6:** all 13 platforms now appear (was previously stuck on CLI)
 - **MCP Servers** — Manage Model Context Protocol servers Hermes connects to. Add via curated presets (GitHub, Linear, Notion, Sentry, Stripe, and more) or fully custom (stdio command + args, or HTTP URL with optional bearer auth). Per-server detail view with enable/disable toggle, environment variable + header editor, tool-include/exclude filters, resources/prompts toggles, request and connect timeouts, OAuth token detection + clearing, and one-click "Test Connection" that runs `hermes mcp test` and surfaces the discovered tool list. Gateway-restart banner appears after config changes that require a reload
 - **Gateway Control** — Start/stop/restart the messaging gateway, view platform connection status, manage user pairing (approve/revoke)
-- **Cron Manager** — View scheduled jobs with pre-run scripts, delivery failure tracking, timeout info, and `[SILENT]` job indicators
+- **Cron Manager** — View scheduled jobs with pre-run scripts, delivery failure tracking, timeout info, and `[SILENT]` job indicators. **New in 1.6:** full write support — create, edit, pause, resume, run-now, and delete jobs from the app
+- **Health** — Component-level status and diagnostics. **New in 1.6:** inline "Run Dump" and "Share Debug Report" buttons (the latter with an upload-confirmation dialog before sending to Nous support)
 - **Log Viewer** — Real-time log tailing for agent.log, errors.log, and gateway.log with level filtering, component filter (Gateway / Agent / Tools / CLI / Cron), clickable session-ID pills that filter to a single session, and text search
-- **Project Dashboards** — Custom, agent-generated dashboards for any project. Define stat boxes, charts, tables, progress bars, checklists, rich text, and embedded web views in a simple JSON file — Scarf renders them with live refresh. Let your Hermes agent build and maintain project-specific visualizations automatically
+- **Settings** — **Restructured in 1.6** into a 10-tab layout: General, Display, Agent, Terminal, Browser, Voice, Memory, Aux Models, Security, Advanced. Exposes ~60 previously hidden config fields including all 8 auxiliary model tasks, container limits, full TTS/STT provider settings, human-delay simulation, compression thresholds, logging rotation, checkpoints, website blocklist, Tirith sandbox, and delegation. One-click **Backup & Restore** via `hermes backup` / `hermes import`. Model picker replaces the old free-text model field, backed by the models.dev cache (111 providers, all major models) with a "Custom…" escape hatch
-- **Settings** — Structured config editor for all Hermes settings including model/provider selection, browser backend, reasoning effort, approval mode, cost display, Fast Mode service tier, interim assistant messages, gateway notify interval, force IPv4, context engine, Honcho eager init, Docker environment, command allowlist, credential management, and one-click **Backup & Restore** via `hermes backup` / `hermes import`

+## Releases
+
+Scarf ships through GitHub releases — the App Store is not supported because Scarf spawns the user-installed `hermes` binary and reads `~/.hermes/` directly, both of which App Sandbox forbids.
+
+Each release goes through a single local script: [scripts/release.sh](scripts/release.sh). The script archives a universal binary, signs it with the Developer ID Application cert, submits to `notarytool`, staples the ticket, produces the distribution zip, signs an appcast entry with Sparkle's EdDSA key, pushes an updated `appcast.xml` to the `gh-pages` branch, creates the GitHub release, and tags `main`.
+
+The Sparkle appcast is served from [awizemann.github.io/scarf/appcast.xml](https://awizemann.github.io/scarf/appcast.xml).
+
+Signing prerequisites (one-time):
+
+- `Developer ID Application` certificate in the login Keychain
+- `scarf-notary` keychain profile registered via `xcrun notarytool store-credentials`
+- Sparkle EdDSA private key in Keychain item `https://sparkle-project.org` (back this up — without it, shipped apps can never receive updates)

+## What's New in 1.6.1
+
+### Auto-updates
+
+Scarf now ships with [Sparkle](https://sparkle-project.org). On launch (and daily thereafter) it checks an EdDSA-signed appcast at [awizemann.github.io/scarf/appcast.xml](https://awizemann.github.io/scarf/appcast.xml). When a new version is available you'll get an in-app update prompt — no more manually downloading zips and dragging into Applications.
+
+You can disable automatic checks or trigger a manual one from **Settings → General → Updates**, the menu bar icon, or the **Scarf → Check for Updates…** menu item.
+
+### Notarized & Developer ID signed
+
+This is the first release that's properly Developer ID signed and notarized by Apple. Gatekeeper accepts it on first launch — no more right-click → Open dance, no more "Scarf cannot be opened because the developer cannot be verified" warnings.
+
+### Fixes
+
+- Chat works correctly when no terminal hermes session is running, and surfaces the real error when it can't reach the agent (b6df…)
+
+### Under the hood
+
+- Tracked `Info.plist` (replacing auto-generation) so signing-relevant keys live in version control
+- New `UpdaterService` wraps Sparkle and is injected via SwiftUI `.environment()`
+- One-command release pipeline at [scripts/release.sh](https://github.com/awizemann/scarf/blob/main/scripts/release.sh) handles archive → sign → notarize → staple → appcast → GitHub release → tag

+
+### Fixes
+
+- **No more bogus "missing credentials" banner on Chat.** The orange "No AI provider credentials detected" warning was firing on the Chat tab whenever no session was selected, even for users whose credentials were configured and working. Root cause: the preflight check only inspected `~/.hermes/.env` and shell environment variables, missing the Credential Pools file at `~/.hermes/auth.json` (the in-app flow introduced in 1.6.0) and `api_key:` fields in `config.yaml`. The check now covers all four locations Hermes itself reads at runtime, so if you've added credentials via **Configure → Credential Pools**, the warning stays hidden.

+## What's New in 2.0
+
+Scarf now manages **multiple Hermes installations** — your local `~/.hermes/` plus any number of remote Hermes instances reached over SSH. Every feature that worked on your Mac now works against a Linux server, a Mac mini on the network, or whatever other host has Hermes installed.
+
+This is a major version bump because the entire service layer was rewritten around a `ServerContext` + `ServerTransport` abstraction, and because the window model changed from single-window-single-server to multi-window-one-server-per-window.
+
+### Multi-server
+
+- **Manage Servers** sheet lets you add, rename, and remove remote servers. Each entry is an SSH target (`user@host`, port, optional identity file, optional `remoteHome` override if your install isn't at `~/.hermes/`).
+- Each window is bound to exactly one server. Open a second window via **File → Open Server** → pick a different server, and the two run side-by-side with independent state — chat, dashboards, activity, sessions, the lot.
+- The menu bar status icon shows a summary across all registered servers (green hare = any Hermes running anywhere).
+- Window-state restoration: quit + relaunch re-opens every window you had open, each reconnected to its bound server.
+
+### Remote over SSH
+
+- **ControlMaster connection pooling** — after the first auth, each remote primitive is a ~5ms tunnel call. Uses the system `ssh`, `scp`, `sftp` so your `~/.ssh/config`, ssh-agent, 1Password/Secretive SSH agents, and ProxyJump all work unchanged.
+- **DB access via atomic snapshots** — Scarf runs `sqlite3 .backup` on the remote (WAL-safe, won't corrupt), flips the snapshot out of WAL mode, and pulls it down with `scp`. Snapshots are cached under `~/Library/Caches/scarf/snapshots/<server-id>/` and re-pulled when the file watcher sees a change on the remote's `state.db`.
+- **ACP chat over SSH** — the Agent Client Protocol tunnel runs `ssh -T host -- hermes acp`. JSON-RPC over stdio travels end-to-end unmodified, so Rich Chat, streaming, tool calls, permission dialogs, and compression all work against the remote agent identically to local.
+- **File watcher** — local uses FSEvents (instant); remote polls `stat` mtime every 3s with ControlMaster keeping the cost bounded. Views auto-refresh on any tick.
+- **Cleanup on server-remove** — deleting a remote closes its ControlMaster socket (`ssh -O exit`), prunes its snapshot cache, and invalidates any process-wide caches keyed to its ID. App launch also sweeps orphaned snapshot dirs whose UUIDs are no longer in the registry.
+
+### Chat UX overhaul
+
+All of these were visible bugs during remote dogfooding and are now fixed on both local and remote:
+
+- **No more white-screen flash** on the first message of a session. `RichChatView` used to swap `ContentUnavailableView` out for the message list, which tore down and recreated the entire ScrollView hierarchy. The empty state now lives inside the ScrollView itself.
+- **No more scroll-jumping to whitespace** at stream start/finish. Replaced six racing `onChange`-driven scroll calls with SwiftUI's built-in `.defaultScrollAnchor(.bottom)`, which is implemented inside the layout pass and doesn't overshoot LazyVStack content.
+- **Resuming a session on a remote now shows its full history.** The DB snapshot is refreshed on session-load — previously it was pulled once on first open and never again, so any messages the remote wrote since launch were invisible.
+- **"Continue from last session" surfaces errors** instead of silently doing nothing when SSH is down.
+- **Typing into a blank Chat always creates a new session.** Previously it auto-resumed the most recently active session in the DB, which often picked up a cron-spawned session that Hermes had already garbage-collected — producing a silent prompt failure.
+- **Failed prompts now explain themselves.** When the agent returns `stopReason: "refusal"`, `"error"`, or `"max_tokens"` with no assistant output, a system message appears under your prompt explaining what happened. No more spinning "Agent working…" forever.
+
+### Correctness — remote SQLite
+
+- The WAL-error spam (`cannot open file at line 51044 of [f0ca7bba1c] — os_unix.c:51044: (2) open(/Users/…/state.db-wal) - No such file or directory`) is gone. `sqlite3 .backup` preserves the source DB's journal mode; the scp'd copy used to try to open a WAL sidecar that doesn't exist. The snapshot script now runs `PRAGMA journal_mode=DELETE` after `.backup` on the remote, and Scarf opens remote snapshots with `file:…?immutable=1` as defense-in-depth.
+- **Concurrent snapshot dedupe** — a new `SnapshotCoordinator` actor makes sure that when Dashboard + Sessions + Activity all ask for a fresh snapshot at the same moment (e.g. on a file-watcher tick), only one SSH backup runs; the other callers await the in-flight pull and share the result.
+
+### Under the hood
+
+- New `ServerContext` value type flows through `.environment()` to every view and ViewModel. Every file and process operation routes through `context.makeTransport()` — `LocalTransport` (`FileManager`, `Process`, FSEvents) or `SSHTransport` (ssh, scp, sftp, mtime polling). The protocol is small enough that each transport is ~400 lines.
+- Swift 6 complete-concurrency sweep: ~230 warnings reduced to 1. `ServerContext`, `HermesPathSet`, `ServerTransport`, all service inits, and every value-type accessor are explicitly `nonisolated`. Hand-written `Codable` conformances for the nine types whose synthesized conformances were inferred `@MainActor` by Swift 6's default-isolation rule (`ACPRequest`, `ACPRawMessage`, `GatewayState`, `PlatformState`, `HermesCronJob`, `CronSchedule`, `CronJobsFile`, `AuthFile`, `AuthEntry`).
+- ACP cwd now comes from the *remote* `$HOME`, probed once on first connect and cached per server. Previously it passed your local Mac's home path to the ACP adapter, which only worked by coincidence when the remote username matched.
+
+### Compatibility
+
+Hermes v0.10.0 is now verified alongside v0.6–v0.9. Scarf builds its session/message `SELECT` columns based on an additive schema detection (`hasV07Schema`), so newer Hermes versions with extra columns don't break queries.
+
+### Migration from 1.6.x
+
+- Sparkle will offer the update automatically. Trigger manually via **Scarf → Check for Updates…** or the menu bar.
+- Your local server is synthesized automatically — existing 1.6.x users see "Local" in the server list with no setup needed.
+- `servers.json` is created on first add-remote. Location: `~/Library/Application Support/scarf/servers.json`.
+- Nothing you configured in 1.6.x (OAuth tokens, credential pools, cron jobs, MCP servers, platform setup) is touched. Those live in `~/.hermes/` and remain the source of truth.
+
+### Known limitations
+
+- Remote file watching is 3s mtime polling (vs. FSEvents on local). If you need sub-second updates on a remote, that's a followup.
+- The `session/load` ACP call against an already-deleted session returns success-with-no-body from the Hermes adapter — Scarf now detects the resulting `stopReason: "refusal"` and surfaces it, but the underlying Hermes behavior is an upstream-adapter bug that should also get a proper error response.

+- Each failure logs a specific warning via `os.Logger` (visible in Console.app under subsystem `com.scarf`).
+- The Dashboard shows an orange banner above the stats with the exact error (e.g. "Permission denied reading `~/.hermes/state.db`") and a **Run Diagnostics…** button.
+- `HermesDataService` exposes a `lastOpenError` so views can explain *why* state.db couldn't be opened, rather than just rendering zeros.
+- Routine "file doesn't exist" cases (optional `skill.yaml` metadata, `gateway_state.json` before Hermes starts, `memories/USER.md` on fresh installs) are detected and **not** logged as warnings — only real errors (permission denied, connection drops, `sqlite3` missing) hit the log. Prevents Console from filling with false-positive noise when directory walks encounter optional files.
+
+### New Remote Diagnostics sheet
+
+Accessible from **Manage Servers → 🩺** per-server button, or by clicking the orange connection pill when Scarf can see the server but can't read Hermes state. Runs fourteen checks in a single SSH session and shows pass/fail for each, plus a targeted hint per failure:
+
+- SSH connectivity and auth
+- Remote user identity and `$HOME` resolution
+- `~/.hermes` directory existence and readability
+- `config.yaml` readable (existence *and* actual read access — the old probe only checked existence)
+- `state.db` readable
+- `sqlite3` installed on the remote (required for the atomic snapshot Scarf pulls)
+- `sqlite3` can actually open `state.db`
+- `hermes` binary on the non-login `$PATH` (what runtime uses)
+- `hermes` binary on the login `$PATH` (what the Test Connection probe uses)
+- `pgrep` available (for the "is Hermes running" check)
+
+One **Copy Full Report** button dumps every check as plain text for bug reports, and a raw-output disclosure panel shows the exact stdout/stderr the remote returned whenever any probe fails — so transport-level problems are self-diagnosing.
+
+The diagnostics script is piped to `/bin/sh -s` on stdin rather than passed as `sh -c <script>` argv. The latter was getting split line-by-line by the remote's login shell (newlines parsed as command separators), which stranded variables set on line 1 in an ephemeral `sh` subprocess that exited before line 2 could use them. Stdin-piping runs the whole script in one `sh` process with variable scope preserved.
+
+### Connection pill gains a "degraded" state
+
+The pill used to be green as long as SSH connected; now after connectivity passes it runs a second-tier check (`test -r $HOME/.hermes/config.yaml`). If that fails, the pill turns **orange** with "Connected — can't read Hermes state" and clicking it opens Remote Diagnostics directly. This is the exact symptom mode in #19, and it's now one click away from a specific answer.
+
+The pill's visual also got a pass: the colored dot is replaced with a state-specific SF Symbol (`checkmark.circle.fill` / `stethoscope` / `arrow.triangle.2.circlepath` / `exclamationmark.triangle.fill`), which reads more like a clickable toolbar tool and doubles as the status signal. No custom pill background anymore — the toolbar's native `.principal` bezel is the frame.
+
+### Auto-suggest the correct `remoteHome` during Add Server
+
+When Test Connection can't find `state.db` at the configured (or default) path, it now also probes the common alternate locations — `/var/lib/hermes/.hermes`, `/opt/hermes/.hermes`, `/home/hermes/.hermes`, `/root/.hermes` — and offers a one-click "Use this" fill if it finds one. Removes the need to know that systemd-installed Hermes lives at `/var/lib/hermes/.hermes` by convention.
+
+### Clearer copy for the `remoteHome` field
+
+The Add Server sheet field is now labeled "Hermes data directory" with a description explaining when you'd override it (systemd service installs, Docker sidecars) and noting that Test Connection auto-suggests.
+
+### README has a new "Remote setup requirements" section
+
+Four concrete prerequisites (SSH, `sqlite3`, `pgrep`, read access to `~/.hermes`) and a troubleshooting paragraph pointing at Remote Diagnostics.
+
+### Migrating from 2.0.0
+
+Sparkle will offer the update automatically. Settings and server list are preserved verbatim — this is purely additive (new diagnostics surface, new error banners, auto-suggest in Test Connection). If you were affected by #19, run Remote Diagnostics after updating; the sheet should pinpoint the specific file access issue and suggest a fix.
+
+### Under the hood
+
+- New types: `RemoteDiagnosticsViewModel`, `RemoteDiagnosticsView`. Both are local to Scarf; no new transport protocol.
+- `HermesFileService` gains `loadConfigResult()`, `loadGatewayStateResult()`, `hermesPIDResult()`, `readFileResult()`, `readFileDataResult()` — Result-returning variants that preserve the error. Legacy `loadConfig()` etc. still exist as thin forwarders for callers that don't need diagnostics.
+- `HermesDataService.open()` records `lastOpenError` with humanized hints for "sqlite3 not installed", "permission denied", and "file not found" — the three failure modes that produce 90% of issue #19 symptoms.
+- `ConnectionStatusViewModel` status enum gains `.degraded(reason:)` between `.connected` and `.error`.
+- `TestConnectionProbe` result enum gains `suggestedRemoteHome: String?` carrying any alternate-location hit.
+
+### Known follow-ups (not in 2.0.1)
+
+- `TestConnectionProbe` uses a direct-argv ssh invocation that's functionally correct but fragile (works by accident when split across the login shell). Should be ported to the stdin-pipe pattern the diagnostics sheet now uses.
+- Remaining `try?`-swallowed read paths beyond the four Dashboard-surfacing ones — Cron, Memory, Skills, MCP Servers, Platforms still silently render empty on read errors. Same fix pattern applies, low priority.
+- `hermesBinaryHint` is only populated when the user clicks Test Connection; if they skip it, ACP chat and CLI calls fall back to bare `hermes` which requires it on the non-interactive PATH (rarely true for `~/.local/bin` installs). The connection-pill's second-tier probe could auto-populate this.
+- Docker-host support: when users SSH to a Docker host, `pgrep` and `~/.hermes/` on the host don't see what's inside the container. Needs a `docker exec` wrapping option per server.

+## What's New in 2.0.2
+
+The actual root cause of [#19](https://github.com/awizemann/scarf/issues/19), found and patched by Scarf's first external contributor. v2.0.1 added the diagnostics UI assuming file-perm root cause; v2.0.2 fixes the underlying bug for everyone, regardless of perms.
+
+### macOS Unix domain socket path limit (the real #19)
+
+OpenSSH's ControlMaster multiplexes our bursty stat/cat/cp traffic over one TCP session per host. The socket path is bound by `bind(2)` to a Unix domain socket — and macOS' `sun_path` is **104 bytes including the NUL terminator**.
+
+Scarf's old socket path was `~/Library/Caches/scarf/ssh/<%C>` where `%C` is OpenSSH's 64-char SHA1 hash of `(local user, host, port, remote user)`. For a username like `alex.maksimchuk`, the full path landed at **105 bytes** — one byte over the limit. ssh exited 255 with `unix_listener: path "..." too long for Unix domain socket`. Our `LogLevel=QUIET` flag (set so ACP's line-delimited JSON stays binary-clean) suppressed the diagnostic, and the user just saw "Remote command exited 255" — which the UI rendered as the silent empty-data state every reporter in #19 described.
+
+The fix is to use a much shorter path:
+
+```swift
+"/tmp/scarf-ssh-\(getuid())"   //  ~17 bytes + 64 hash + sep + NUL = ~83 bytes
+```
+
+Per-user uid suffix keeps two local users' sockets from colliding in the shared `/tmp`, and 0700 perms on the dir keep them inaccessible to other users.
+
+**Massive thanks to Alex Maksimchuk ([@aliatx2017](https://github.com/aliatx2017)) — Scarf's first external PR contributor — for diagnosing and patching this in [#20](https://github.com/awizemann/scarf/pull/20).** That diagnosis only happened because Alex bothered to read the codebase, reproduce against multiple usernames including a Termux/Android instance, and walk back from the cryptic exit code to the actual `bind()` failure. This release wouldn't exist without that work.
+
+### Hardening on top of the fix
+
+Three additions on top of Alex's patch, layered in via separate commits to keep the original change reviewable:
+
+- **Defensive ownership check on the socket dir.** `/tmp` is world-writable, so a malicious local user could pre-create `/tmp/scarf-ssh-<uid>` and trick Scarf into using a hostile directory (we'd silently fail to chmod it back to 0700, since we wouldn't own it). `ensureControlDir` now uses POSIX `mkdir(0700)` (atomic, sets perms at create time) and on `EEXIST` runs `lstat` to verify the entry is a directory we own with mode 0700 — symlink → refuse, wrong owner → refuse + log to `os.Logger`, wrong mode → repair. Closes the `/tmp` pre-creation hole that's the standard concern for any per-user `/tmp` path.
+- **Launch-time sweep of stale sockets.** `ServerRegistry.sweepOrphanCaches` already prunes orphaned snapshot directories on launch; it now also removes ControlMaster socket files older than 30 minutes. Socket basenames are `%C` hashes (not ServerIDs), so we can't keep "still registered" sockets the way the snapshot sweep does — but `ControlPersist` is 600s, so anything older than 30 minutes is guaranteed to be a dead orphan from a crashed master, an unclean app exit, or a server removed while another Scarf instance was holding the dir. Keeps `/tmp/scarf-ssh-<uid>/` from accumulating indefinitely until reboot, while leaving any concurrent Scarf instance's live sockets untouched.
+- **Regression test for the path-length invariant.** `scarfTests` was a stub — it now has two tests: one asserting `controlDirPath().utf8.count + 1 + 64 + 1 ≤ 104` (would have caught the original #19 bug in CI), one asserting the path includes the current uid (pins the per-user-isolation invariant against a future "simplification" that drops it).
+
+### v2.0.1 diagnostics work is still useful
+
+The diagnostics sheet, orange "degraded" pill, dashboard error banner, and `remoteHome` auto-suggest from v2.0.1 all still ship — they just turn out not to have been the right diagnosis for the original three reporters. They remain valuable for the *other* connection-failure modes they were designed to surface (missing `sqlite3` on the remote, real permission errors, container/host visibility gaps, custom Hermes data directories). If you upgrade to v2.0.2 and *still* see incomplete data, run Remote Diagnostics from **Manage Servers → 🩺** and the sheet will tell you why.
+
+### Migrating from 2.0.0 / 2.0.1 / draft 2.0.1
+
+Sparkle will offer the update automatically. Settings and server list are preserved verbatim. The first time v2.0.2 connects to a remote, it'll create `/tmp/scarf-ssh-<uid>/` with mode 0700; the old `~/Library/Caches/scarf/ssh/` directory becomes unused (you can delete it manually, or leave it — macOS will sweep it eventually).
+
+The previous v2.0.1 draft download remains available for anyone who already grabbed it — it's still a valid build with the diagnostics work. v2.0.2 is the recommended upgrade path.
+
+### Reporters of #19
+
+@cmalpass, @flyespresso, @maikokan — please grab v2.0.2 and confirm the dashboard populates without needing to run Remote Diagnostics first. If it still doesn't, the diagnostics sheet should now have a much better chance of pinpointing what's left.

+## What's New in 2.1.0
+
+Scarf now speaks seven languages and has a proper slash-command menu in the chat. The language work closes [#13](https://github.com/awizemann/scarf/issues/13) and opens the door for community contributions of additional locales.
+
+### Multi-language support
+
+The UI is now fully translated to **Simplified Chinese, German, French, Spanish, Japanese, and Brazilian Portuguese** on top of the existing English. Scarf respects the system language by default; override per-app from **System Settings → Language & Region → Apps → Scarf**.
+
+- **644 source strings** catalogued. **583 translated per locale** — the remaining ~60 are deliberate fall-throughs to English: proper nouns (Scarf, Hermes, OAuth, MCP, SSH), brand names (Docker, Daytona, Singularity, BlueBubbles), format-only tokens (`%lld`, `·`, `•`), and config-literal placeholders (`my_server`, `npx`, `sk-…`).
+- **Locale-aware number and date formatting.** Previous builds hardcoded POSIX-style decimal separators (`$12.34`) and English unit names (`"MB"`, `"K"`, `"M"`). Currency now routes through `.formatted(.currency(code: "USD"))`, byte sizes through `.byteCount(style: .file)`, token counts through `.notation(.compactName)`, and the day-of-week chart through `Calendar.current.shortWeekdaySymbols` — so German users see `15,2 MB`, Japanese users see `15.5万 tokens`, and the activity heatmap starts on the locale's first weekday.
+- **Microphone permission prompt localized** — the system dialog that appears the first time you enable voice chat now reads in the user's language.
+
+#### How the translation work shipped
+
+Three stacked PRs to keep each piece independently reviewable, all AI-translated with the bar explicitly set low so native speakers can iterate:
+
+1. **[#22](https://github.com/awizemann/scarf/pull/22) — String Catalog infrastructure.** Added `Localizable.xcstrings` + `InfoPlist.xcstrings`, expanded `knownRegions` with the six new locales, and fixed the locale-aware number formatters mentioned above. No user-visible English-locale change; the groundwork only.
+2. **[#24](https://github.com/awizemann/scarf/pull/24) — Audit burn-down.** Swept the codebase for "silently un-localizable" patterns that look fine in Xcode's catalog but leak English at runtime: `Text(cond ? "A" : "B")` routes through the String overload instead of `LocalizedStringKey`, as do `Label(stringVar, systemImage:)`, `.help(stringVar)`, and composite format strings with translatable text suffixes. ~40 sites refactored, covering Chat voice/TTS toggles, Logs pickers, Insights period + day names, MCPServer test result, Profiles, SignalSetup, QuickCommands, ConnectionStatusPill. Without this PR the translations would have landed but ~40 visible strings would still have rendered in English.
+3. **[#25](https://github.com/awizemann/scarf/pull/25) — Translations + contributor path.** The six locale JSONs + a 90-line merge script + a "Adding a Language" section in `CONTRIBUTING.md`. The sidebar and Settings tab bar fix also shipped here after smoke-testing revealed they were still missed — `Label(section.rawValue, …)` goes to the String overload just like the audit cases.
+
+#### Contributing a new language
+
+Per-locale source of truth lives in [`tools/translations/<locale>.json`](https://github.com/awizemann/scarf/tree/main/tools/translations). Each entry is a plain `{ "English": "Translation" }` map — keys you omit fall through to English at runtime. Workflow is: fork, drop a JSON, run `python3 tools/merge-translations.py`, open a PR. The full bar is documented in [CONTRIBUTING.md → Adding a Language](https://github.com/awizemann/scarf/blob/main/CONTRIBUTING.md#adding-a-language).
+
+Native-speaker review of the initial six locales is welcome — AI translation gets us most of the way, but idiom and tone are better with someone who actually uses the language. Post a PR against the relevant `<locale>.json` and it'll land as a follow-up.
+
+### Chat slash-command menu
+
+Type `/` in Rich Chat and a floating menu appears above the input with every command the connected agent has advertised via ACP's `available_commands_update`, plus any user-defined `quick_commands:` from `~/.hermes/config.yaml`. ↑/↓ to navigate, Tab or Enter to complete, Esc to dismiss. Commands with argument hints (e.g. `/compress <topic>`) insert a trailing space so you can start typing the argument immediately.
+
+The filter uses pure-prefix match and re-renders on every query — the old menu had a description-fallback filter and a cached child view that together pinned `/help` on-screen regardless of what you typed. The dedicated `/compress` button is hidden once the menu has more than one command; it only surfaces when `/compress` is the single advertised slash command, preserving the v2.0 one-click compression flow for that case.
+
+### Chat UX polish
+
+- **Auto-scroll on send and on completion.** `.defaultScrollAnchor(.bottom)` handles slow streaming fine, but rapid slash-command responses (common once the menu lands) outran the anchor and left the reply off-screen. Now the list explicitly scrolls to the latest message when you submit and again when the prompt finishes.
+- **Loading state.** `ChatViewModel.isPreparingSession` is true during Starting / Creating / Loading / Reconnecting. While true, the message list swaps its empty-state placeholder for a spinner — non-blocking, just a view inside the ScrollView.
+- **Empty-state centering.** The "Start a new session or resume an existing one" placeholder was positioned with a fixed `.padding(.vertical, 80)` that looked wrong at extreme window sizes. Replaced with Spacers inside `.containerRelativeFrame(.vertical)` so it sits in the true vertical center of the chat pane.
+- **Session-load whitespace bug.** Opening a session used to render a blank viewport you'd have to scroll up from — the fix was `LazyVStack` → `VStack` in `RichChatMessageList`. LazyVStack's estimated row heights were fooling `.defaultScrollAnchor(.bottom)` into overshooting real content; VStack measures every row upfront so the anchor has real heights to work with.
+
+### Under the hood
+
+- **String Catalog build pipeline.** `SWIFT_EMIT_LOC_STRINGS` + `STRING_CATALOG_GENERATE_SYMBOLS` are enabled; keys extract automatically on IDE build. Headless builds use `xcrun xcstringstool sync` to merge the per-source `.stringsdata` files into the catalog (wrapped by [`tools/merge-translations.py`](https://github.com/awizemann/scarf/blob/main/tools/merge-translations.py) when applying JSON translations).
+- **New docs.** [`scarf/docs/I18N.md`](https://github.com/awizemann/scarf/blob/main/scarf/docs/I18N.md) covers the catalog setup, the patterns that silently bypass localization (and their fixes), and which strings are intentionally kept verbatim. Anyone adding UI copy should read the "Guardrails when writing new UI code" section to avoid re-introducing the leaks #24 cleaned up.
+
+### Migrating from 2.0.x
+
+Sparkle will offer the update automatically. No config migration needed. The first launch after update picks up the system locale — if you want English even on a non-English macOS, set **System Settings → Language & Region → Apps → Scarf → English**.
+
+### Thanks
+
+- [Onion3](https://github.com/Onion3) for filing [#13](https://github.com/awizemann/scarf/issues/13) back in April. The single-locale ask turned into a six-locale rollout.
+- Future translators: if you spot a weird AI translation in your language, open a PR against `tools/translations/<locale>.json`. The bar is explicitly low — we'd rather have a 95%-correct translation shipped and iterated on than hold everything for perfection.

+## What's New in 2.2.0
+
+Scarf projects can now travel. This release introduces **Project Templates** — a shareable `.scarftemplate` bundle format that packages a project's dashboard, agent instructions, skills, cron jobs, and a typed configuration schema into a single file anyone can install with one click. Bundles are agent-portable by design: every template ships with a cross-agent [`AGENTS.md`](https://agents.md/) so the instructions work natively in Claude Code, Cursor, Codex, Aider, Jules, Copilot, Zed, and every other agent that reads the Linux Foundation standard.
+
+This is also the first release to ship a public **template catalog website** — a static site generated from `templates/<author>/<name>/` in this repo, previewed at [awizemann.github.io/scarf/templates/](https://awizemann.github.io/scarf/templates/), with a CI-enforced validator for community submissions.
+
+### Project Templates
+
+- **Bundle format: `.scarftemplate`.** A zip carrying a `template.json` manifest, the project's dashboard, a required `AGENTS.md` (the [Linux Foundation cross-agent instructions standard](https://agents.md/) — reads natively in Claude Code, Cursor, Codex, Aider, Jules, Copilot, Zed, and more), a README shown in the installer, optional per-agent instruction shims (`CLAUDE.md`, `GEMINI.md`, `.cursorrules`, `.github/copilot-instructions.md`), optional namespaced skills, optional cron job definitions, and an optional memory appendix.
+- **Install preview sheet.** Before anything touches disk, Scarf shows you the exact project directory that will be created, every file inside it, every skill that will be namespaced under `~/.hermes/skills/templates/<slug>/`, every cron job that will be registered (always paused — you enable each one manually), and a live diff of the memory appendix against your existing `MEMORY.md`. Markdown fields — the README, field descriptions, cron prompts — render inline. The manifest's content claim is cross-checked against the actual zip entries so a bundle can't hide files from the preview.
+- **`scarf://install?url=…` deep links.** Register Scarf as the handler for the `scarf` URL scheme so a future catalog site can link one-click installs straight into the app. Only `https://` payloads are accepted; `file://`, `javascript:`, and `http://` are refused on principle. A 50 MB size cap keeps a malicious link from exhausting disk. The URL never auto-installs — the preview sheet is always user-confirmed.
+- **Install-time token substitution.** Template authors use `{{PROJECT_DIR}}`, `{{TEMPLATE_ID}}`, and `{{TEMPLATE_SLUG}}` placeholders in cron prompts; the installer resolves them to absolute paths at install time so the registered cron job works regardless of where Hermes sets CWD.
+- **Export any project as a template.** Select a project, open the new Templates menu in the Projects toolbar, fill in a handful of fields (id, name, version, description, optional author + category + tags), tick the skills and cron jobs you want to include, optionally drop in a memory snippet, and save. The exporter carries the authored configuration schema forward but **never** the user's values — exports are safe on projects with live config.
+- **No-overwrite, reversible by design.** Installed templates drop a `<project>/.scarf/template.lock.json` recording exactly what they wrote — every project file, skill path, cron job name, memory block id, and Keychain reference. Installing the same template id twice is refused at the preview step so you don't accidentally double-append to `MEMORY.md`.
+- **Safe globals.** Skills install to `~/.hermes/skills/templates/<slug>/<skill-name>/` so they never collide with your own skills. Cron jobs are prefixed with `[tmpl:<id>]` and start paused. The installer **never** touches `~/.hermes/config.yaml`, `auth.json`, sessions, or any credential-bearing path.
+
+### Template Configuration (schemaVersion 2)
+
+Templates can now declare a typed configuration schema that drives a form step during install — no more "edit a `sites.txt` file to get started."
+
+- **Typed field vocabulary.** Seven field types: `string`, `text` (multiline), `number` (with `min`/`max`), `bool`, `enum` (with `{value, label}` options), `list` (of strings, with `minItems`/`maxItems`), and `secret` (routed to the macOS Keychain). Constraints per type — `pattern` for regex, `minLength`/`maxLength` for text, etc. — are enforced at install and at edit time.
+- **Configure step in the install flow.** If the template declares a schema, a **Configure** screen is inserted between "pick parent directory" and the preview sheet. Non-secret values land in `<project>/.scarf/config.json`; secrets land in the macOS Keychain with a service name of `com.scarf.template.<slug>` and an account keyed to the project-directory hash (so two installs of the same template in different dirs don't collide on Keychain entries).
+- **Post-install Configuration editor.** A slider icon in the dashboard header opens the same form pre-filled with the current values. Change a site, rotate a token, toggle a feature — the cron job picks up the new values on its next run. Secrets are never echoed back ("Saved in Keychain — leave empty to keep the stored value").
+- **Model recommendations.** Templates can suggest a preferred model (`claude-sonnet-4.5`, `claude-haiku-4`, `gpt-4.1`, etc.) with a rationale. Scarf surfaces the recommendation in the configure sheet without auto-switching your active model — always your call.
+- **Secrets are tracked in the lock file.** Uninstalling a template runs `SecItemDelete` on every Keychain ref recorded at install, so a full clean-up leaves nothing behind. Absent entries (user already cleaned them) are no-ops.
+
+### Template Catalog
+
+A Sparkle-style pipeline for community-contributed templates, living on the same `gh-pages` branch as the auto-update feed.
+
+- **Static site.** [awizemann.github.io/scarf/templates/](https://awizemann.github.io/scarf/templates/) — generated from every `templates/<author>/<name>/` directory. Each template gets a detail page showing the README, a live preview of the post-install dashboard, and the configuration schema rendered with human-readable constraint summaries. One-click install via the `scarf://install?url=…` button.
+- **Stdlib-only Python validator.** `tools/build-catalog.py` is a no-external-dependencies Python script that mirrors the Swift-side schema and validation invariants (supported widget types, supported field types, `contents` claim verification, secret-with-default rejection, bundle-size cap, high-confidence secret patterns). Run it locally with `./scripts/catalog.sh check` before submitting a PR.
+- **CI gate on PRs.** [`.github/workflows/validate-template-pr.yml`](https://github.com/awizemann/scarf/blob/main/.github/workflows/validate-template-pr.yml) runs the validator + its 24-test suite on every PR touching `templates/`, the validator itself, or its tests. Failing PRs get an inline comment with the last 3 KB of the validator output; passing PRs get a tailored checklist naming the specific template directory being changed.
+- **Install-URL hosting.** Bundles are raw-served from `main` at `https://raw.githubusercontent.com/awizemann/scarf/main/templates/<author>/<name>/<name>.scarftemplate`. No per-template GitHub Releases ceremony.
+- **Dogfood: the site uses Scarf's dashboard format.** `site/widgets.js` is ~300 lines of vanilla JS that renders a `ProjectDashboard` JSON using the same widget vocabulary the app uses, so each detail page's "live preview" is the actual dashboard the user will get.
+
+### Example template: `awizemann/site-status-checker`
+
+Ships as the first catalog entry and exercises every v2.2 surface. [See it in the catalog →](https://awizemann.github.io/scarf/templates/awizemann-site-status-checker/)
+
+- Configure step asks for a list of URLs and a per-URL timeout.
+- A paused cron job runs daily at 09:00 (editable from the Cron sidebar), does HTTP GETs with 3-redirect follow, writes a timestamped results table to `status-log.md`, updates the dashboard's Sites Up / Sites Down / Last Checked stat widgets plus the Watched Sites list, and rewrites the Site tab's webview URL to the first configured site.
+- Works in any agent — the `AGENTS.md` is the single source of truth; no per-agent shim needed.
+
+### Site tab
+
+A dashboard with at least one `webview` widget now exposes a **Site** tab next to Dashboard. Useful for templates that watch something renderable (a site, a preview endpoint, a Grafana panel). The `site-status-checker` example rewrites the webview URL to the first configured site on every cron run, so the tab stays in sync with live config.
+
+### Using templates
+
+- **Install from file:** Projects → Templates → *Install from File…*, pick a `.scarftemplate` from disk.
+- **Install from URL:** Projects → Templates → *Install from URL…*, paste an https URL.
+- **Install from the web:** click any `scarf://install?url=…` link in a browser.
+- **Export:** select a project → Projects → Templates → *Export "&lt;name&gt;" as Template…*, fill the form, save.
+- **Edit config post-install:** slider icon in the dashboard header.
+- **Uninstall:** right-click the project in the sidebar → *Uninstall Template (remove installed files)…*, or click the uninstall icon in the dashboard header. The preview sheet lists every file, cron job, Keychain secret, and memory block that will be removed, plus every user-created file that will be preserved.
+
+### UX clarifications
+
+- **Remove from List vs. Uninstall Template.** Sidebar context-menu labels clarified so you can see at a glance whether a click is destructive. *Remove from List (keep files)…* is registry-only — nothing on disk is touched, cron jobs stay, Keychain secrets stay. A confirmation dialog spells this out before the click lands. *Uninstall Template (remove installed files)…* is the full, lock-driven cleanup.
+- **Post-uninstall "folder kept" banner.** When the uninstaller preserves the project directory because the cron wrote a `status-log.md` (or the user dropped files in there), the success view now explicitly lists the preserved paths with a pointer to delete the folder from Finder if desired.
+- **Run Now no longer blocks on agent runs.** The Cron sidebar's Run Now button used to show a "Run failed" toast whenever an agent job ran longer than 60 s — even when the job was finishing correctly in the background. Run Now now shows "Agent started — dashboard will update when it finishes" immediately and the dashboard watcher picks up the completed state when it lands (timeout bumped to 300 s for the catch-stuck-process case).
+
+### Uninstall
+
+- **One-click uninstall** driven by `template.lock.json`. The preview sheet lists every file, cron job, Keychain ref, and memory block that will be removed, and every user-created file that will be preserved.
+- **User content is never removed.** Files you (or the agent) added to the project dir after install — like a `sites.txt` or `status-log.md` — are detected and listed as "keep" in the preview. The project directory itself is removed only if nothing user-owned is left inside.
+- **Clean global state.** The isolated `~/.hermes/skills/templates/<slug>/` namespace is removed wholesale. Tagged cron jobs are removed via `hermes cron remove`. Every recorded Keychain ref is cleared via `SecItemDelete`. The memory block between the `<!-- scarf-template:<id>:begin/end -->` markers is stripped, leaving the rest of MEMORY.md intact. The project registry entry is removed last.
+- **No undo.** Uninstall is destructive — to reinstall, run the install flow again.
+
+### Under the hood
+
+- New models in `Core/Models/ProjectTemplate.swift` (manifest, inspection, install plan, lock file v2) and `Core/Models/TemplateConfig.swift` (schema + typed values + Keychain ref model).
+- `Core/Services/ProjectTemplateService.swift` unzips, parses, and validates; `ProjectTemplateInstaller.swift` executes the plan with preflight + fail-fast semantics; `ProjectTemplateUninstaller.swift` reverses an install driven by the lock file; `ProjectTemplateExporter.swift` builds bundles from a live project + selections.
+- `Core/Services/ProjectConfigService.swift` owns load/save/validation of `<project>/.scarf/config.json` + secret resolution; `Core/Services/ProjectConfigKeychain.swift` is the thin `SecItemAdd`/`Copy`/`Delete` wrapper (the only Keychain consumer in Scarf today).
+- `Core/Services/TemplateURLRouter.swift` is the process-wide landing pad for `scarf://` URLs so a cold-launch browser click still reaches the install sheet.
+- New Swift Testing suites covering 57 tests across the service / installer / uninstaller / exporter / config / Keychain / URL-router paths.
+- New Python validator (`tools/build-catalog.py`) + test suite (`tools/test_build_catalog.py`, 24 tests) mirrors the Swift invariants for the CI gate and the site generator. Schema is Swift-primary — additions go to Swift first, Python mirrors.
+- `scripts/catalog.sh` wraps the validator with `check / build / preview / serve / publish` subcommands that parallel the `scripts/release.sh` shape.
+
+### Migrating from 2.1.x
+
+Sparkle will offer the update automatically. No config migration needed. Existing projects are untouched — templates are additive. If you had a v2.2.0-dev install of the earlier `project-templates` branch, uninstall and reinstall any previously-installed templates to pick up the schema-version-2 lock file.
+
+### Documentation
+
+- [Project Templates wiki page](https://github.com/awizemann/scarf/wiki/Project-Templates) — installing, exporting, configuring, authoring, uninstalling.
+- [Catalog site](https://awizemann.github.io/scarf/templates/) — the public catalog with live dashboard previews.
+- [`templates/CONTRIBUTING.md`](https://github.com/awizemann/scarf/blob/main/templates/CONTRIBUTING.md) — how to submit a template via PR.
+- [Architecture notes in root `CLAUDE.md`](https://github.com/awizemann/scarf/blob/main/CLAUDE.md#project-templates) — service-layer map, Keychain scheme, schema-drift discipline.
+
+### Thanks
+
+Thanks to everyone who tested drafts of the install flow, caught the "Run Now blocks on agent" bug, and pushed on the Remove-vs-Uninstall UX until it was clear. A 2.3 follow-up will extend the catalog validator to enforce per-field-type constraints at PR-time (currently enforced on install but not at submission).

+# Internationalization (i18n)
+
+Scarf uses Apple's modern **String Catalog** workflow. Source strings are auto-extracted from `Text("…")` and `String(localized: …)` literals into [`scarf/scarf/Localizable.xcstrings`](../scarf/Localizable.xcstrings) at build time (when built in Xcode.app; `xcodebuild` alone emits per-source `.stringsdata` but does not merge back into the catalog). Info.plist keys are localized via [`scarf/scarf/InfoPlist.xcstrings`](../scarf/InfoPlist.xcstrings).
+
+## Languages
+
+| Locale | Status |
+|---|---|
+| `en` (English) | Base / source |
+| `zh-Hans` (Simplified Chinese) | AI-translated, native-speaker review welcome |
+| `de` (German) | AI-translated, native-speaker review welcome |
+| `fr` (French) | AI-translated, native-speaker review welcome |
+| `es` (Spanish) | AI-translated, native-speaker review welcome |
+| `ja` (Japanese) | AI-translated, native-speaker review welcome |
+| `pt-BR` (Portuguese, Brazil) | AI-translated, native-speaker review welcome |
+
+Canadian French users are served by base `fr`. `fr-CA` will be added only if a concrete Québec-specific bug is reported.
+
+### Translation workflow
+
+Source-of-truth per locale lives in `tools/translations/<locale>.json` — a flat `{ "English": "Translation" }` map. The merge step writes those into `scarf/scarf/Localizable.xcstrings` via:
+
+```bash
+python3 tools/merge-translations.py
+```
+
+Keys absent from a locale file fall back to English at runtime — this is deliberate for proper nouns (Scarf, Hermes, Anthropic, OAuth, SSH…) and format-only strings (`%lld`, `%@ → %@`, `•`). Re-running the merge is idempotent; iterate on a JSON and re-merge.
+
+Contributor path for new languages is documented in the repo root [CONTRIBUTING.md](../../CONTRIBUTING.md#adding-a-language).
+
+## Adding a new language
+
+1. Xcode → Project → Info → Localizations → `+` (add locale).
+2. Ensure the locale code is also listed in `knownRegions` of `scarf.xcodeproj/project.pbxproj`.
+3. Open `Localizable.xcstrings` in Xcode; the new locale appears as an empty column — translate or use Xcode's AI suggestions.
+4. Repeat for `InfoPlist.xcstrings` (microphone usage, etc.).
+5. Smoke-test via scheme language override (Edit Scheme → Run → App Language).
+
+## Adding translations (AI-first workflow)
+
+For the three supported non-English locales we use Xcode's built-in AI translation:
+
+1. Open `Localizable.xcstrings` in Xcode.
+2. Select untranslated rows for a locale → right-click → **Translate** (Xcode 26+ provides GPT-backed suggestions with context from the surrounding code comment).
+3. Review each suggestion before marking **Translated**.
+4. For terms that should NOT translate (proper nouns like *Scarf*, *Hermes*, *Anthropic*; env var names; file paths), wrap the source site in `Text(verbatim: "…")` so the key never hits the catalog.
+
+## Guardrails when writing new UI code
+
+`Text("literal")` auto-localizes. These patterns **silently leak English** and need explicit handling:
+
+| Pattern | Fix |
+|---|---|
+| `Text(someStringVar)` | `Text(LocalizedStringResource("key"))` or pass a `LocalizedStringKey` down the view tree |
+| `"Hello " + name` | `String(localized: "Hello \(name)")` |
+| `String(format: "$%.2f", cost)` | `cost.formatted(.currency(code: "USD").precision(.fractionLength(2)))` |
+| `String(format: "%.1f MB", size)` | `Int64(size).formatted(.byteCount(style: .file))` |
+| `String(format: "%.1fM", n)` | `n.formatted(.number.notation(.compactName))` |
+| Custom `DateFormatter` with fixed `dateFormat` | `date.formatted(.dateTime.month().day().year())` |
+| `.help(stringVar)` | Compute a `LocalizedStringKey` or use `.help(Text(…))` |
+| `Button(stringVar)` | `Button(LocalizedStringResource("key")) { … }` |
+
+Strings that are **user data** (session titles, memory file contents, log lines, shell commands shown in UI, file paths) should pass through without localization — this happens naturally when the value is a `String` variable, since those overloads skip the catalog.
+
+## Audit status
+
+Phase 1b (the `multi-language` PR) closed every tracked site from the original audit:
+
+- **Category A high-priority (ternary UI copy)** — converted to `Text`-ternary form so each branch routes through `LocalizedStringKey`.
+- **Category A medium-priority (enum `.rawValue` displays)** — each enum now exposes `displayName: LocalizedStringResource` and call sites use it. `LogEntry.LogLevel` (technical jargon) stays verbatim.
+- **Category A lower-priority (displayName passthroughs)** — wrapped with `Text(verbatim:)` for proper nouns / user data (`HermesToolPlatform`, `ServerRegistry.Entry`, `MCPServerPreset`). `MCPTransport.displayName` promoted to `LocalizedStringResource`.
+- **Category B (composite format strings)** — migrated to `Text("\(arg) suffix")` with `LocalizedStringKey` or to `.percent` / `.currency` FormatStyle.
+- **Category C (hard-coded day names)** — replaced with `Calendar.current.shortWeekdaySymbols`, re-indexed to match the existing Mon=0 data model.
+- **Category D (`.help(stringVar)` sites)** — `ConnectionStatusPill` now returns `Text` from its `labelText` / `tooltipText` properties.
+
+If you spot a new silently-un-localizable site during translation review, prefer the patterns in the table above over one-off workarounds.
+
+### Non-blocking (intentional verbatim)
+
+The following are correct as-is because they pass user data or machine-readable content through to the UI:
+
+- Session titles, message content, memory / skill / YAML file contents, log lines, shell commands, file paths, session IDs, model IDs, credential sources, URL strings.
+
+If we later need to badge these (e.g. "(empty)" placeholder), the badge itself becomes a localizable key while the data passthrough stays verbatim.

+/// Drives the `hermes auth add <provider> --type oauth` flow via `Process` +
+/// pipes instead of SwiftTerm. The embedded terminal approach turned out to
+/// have two problems:
+///
+///   1. Python's `webbrowser.open` called from a subprocess doesn't reliably
+///      open the user's browser — the macOS `open` command can fail silently
+///      depending on how the parent app was launched.
+///   2. Even when it works, users can't easily copy the URL from a terminal
+///      emulator to click or share.
+///
+/// This controller runs hermes with `--no-browser`, captures stdout/stderr,
+/// regex-extracts the authorization URL, and exposes it to the UI as a plain
+/// string. The UI shows a real "Open in Browser" button (via NSWorkspace) and
+/// a code input text field. Submitting writes the code + newline to hermes's
+/// stdin pipe, which Python's `input()` reads normally — verified in shell
+/// testing that hermes accepts piped stdin when a TTY isn't available.
+///
+/// Hermes exits 0 even on "login did not return credentials" failures, so we
+/// detect success by scanning output for failure markers AND by letting the
+/// calling VM reload `auth.json` to see whether a new credential actually
