docs: v2.3.0 release notes + README What's New

Prep commit for the v2.3 release. Covers the 16 feature + fix commits landed on the v2.3-projects branch: - releases/v2.3.0/RELEASE_NOTES.md — new file. release.sh picks this up automatically as the GitHub release body at tag time. Sections: sidebar grows up (folders/rename/archive/search/ keyboard jumps), per-project Sessions tab + sidecar, the AGENTS.md marker-block injection (with the invariants — secret-safe, idempotent, bounded, non-fatal, bare-project friendly — called out explicitly), chat-UI project awareness (folder chip + nav title), window-layout cleanup, under-the- hood (new services, 22 new tests), migration, thanks. - README.md — "What's New in 2.3" block at the top; demotes the prior 2.2 block to "Previously, in 2.2" (condensed to the four most user-facing points since the full 2.2 notes live at the release link). - Localizable.xcstrings — Xcode auto-regen from the new string literals introduced across the v2.3 feature commits (folder chip tooltip, Sessions tab header, etc.). Riding along. 93/93 Swift tests still pass. No code change here — pure docs. Wiki Home + Release-Notes-Index updates land as a separate wiki commit after the release is cut (standard post-release chore per CLAUDE.md).

+## 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.

 ## 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.
+
+### Project-scoped chat + Scarf-managed AGENTS.md context (v2.3)
+
+v2.3 adds a per-project Sessions tab and a "New Chat" button that spawns `hermes acp` with `cwd = project.path`. Session-to-project attribution is persisted in a Scarf-owned sidecar at `~/.hermes/scarf/session_project_map.json` — the ACP wire protocol has no project-metadata hook (extra params are silently dropped), and `state.db` has no cwd column, so the sidecar is Scarf's source of truth for "which project does this session belong to?" Managed by [SessionAttributionService.swift](scarf/scarf/Core/Services/SessionAttributionService.swift); read by the per-project [ProjectSessionsView.swift](scarf/scarf/Features/Projects/Views/ProjectSessionsView.swift).
+
+**Giving the agent project awareness.** Hermes auto-reads a context file from the session's cwd at startup — priority order `.hermes.md` → `HERMES.md` → `AGENTS.md` → `CLAUDE.md` → `.cursorrules`, first match wins, 20KB cap. We lean on that by writing a Scarf-managed block into `<project>/AGENTS.md` before opening the session. Service: [ProjectAgentContextService.swift](scarf/scarf/Core/Services/ProjectAgentContextService.swift). Block shape:
+
+```
+<!-- scarf-project:begin -->
+## Scarf project context
+_Auto-generated by Scarf — do not edit between the begin/end markers._
+
+You are operating inside a Scarf project named **"<Project Name>"**. …
+
+- **Project directory:** `<absolute path>`
+- **Dashboard:** `<path>/.scarf/dashboard.json`
+- **Template:** `<author/id>` v<version>    <!-- template-installed only -->
+- **Configuration fields:** `field_a`, `field_b (secret — name only, value stored in Keychain)`
+- **Registered cron jobs:** `[tmpl:<id>] <name>` — schedule …, currently paused|enabled
+- **Uninstall manifest:** `<path>/.scarf/template.lock.json`  <!-- when present -->
+
+Any content below this block is template- or user-authored; preserve and defer to it.
+<!-- scarf-project:end -->
+```
+
+**Invariants.**
+
+- **Secret-safe.** Block surfaces field NAMES, never VALUES. A project with a Keychain-stored secret shows `api_token (secret — name only, …)`; the Keychain ref URI and any plaintext value never appear. Auditable by `refreshListsFieldNamesNotValues` in `ProjectAgentContextServiceTests`.
+- **Idempotent.** Two refreshes with unchanged state produce byte-identical output. The write is skipped entirely when no delta, avoiding file-watcher churn.
+- **Bounded.** Everything outside the markers is preserved on every refresh. Template-author AGENTS.md content lives safely below the block.
+- **Non-fatal.** `ChatViewModel.startACPSession` calls refresh with `try?` + log — a failed write doesn't block the chat from starting; worst case is the session loses project awareness.
+- **Refresh timing.** Called BEFORE `client.start()` so the block lands before Hermes's session-boot context scan. Skipping this ordering = the agent sees stale context from the previous refresh (or nothing, on fresh projects).
+
+**Template-author contract.** A template shipped via the catalog should include an `AGENTS.md` with the template's operational instructions. Authors leave the `<!-- scarf-project -->` region alone — Scarf populates it at chat-start time. Everything below is template-owned and preserved.
+
+**Known caveat.** If any parent directory of the project contains `.hermes.md` or `HERMES.md`, those shadow the project's `AGENTS.md` (higher in Hermes's priority order). No fix in v2.3 — deferred to v2.4 pending user input on how to handle authored `.hermes.md` files.
+
+## 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.

+## 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 2.0
+## What's New in 2.3
+
+- **Projects sidebar grows up** — group projects into folders, rename / archive / unarchive in place, filter the list with ⌘F, jump to the first nine with ⌘1–⌘9. Archived projects hide by default; a toggle in the bottom bar surfaces them. Non-destructive on the v2.2 registry file — downgrade stays clean.
+- **Per-project Sessions tab** — alongside Dashboard and Site. Shows chats attributed to the project, with a **New Chat** button that spawns `hermes acp` with the project's directory as the session cwd and attributes the result via a Scarf-owned sidecar (`~/.hermes/scarf/session_project_map.json`). Click any listed session to resume it with project context automatically restored.
+- **Agent actually knows what project it's in** — the architectural headline. Every project-scoped chat gets a Scarf-managed block auto-injected into the project's `AGENTS.md` before the session starts. Hermes reads AGENTS.md from the session's cwd at startup and picks up the block as part of its system prompt. Ask the agent *"what project am I in?"* and it answers with the project name, directory, template id + version, configuration field names, and registered cron jobs — pulled from the injected block. Secret-safe (field names only, never values), idempotent, bounded to `<!-- scarf-project:begin/end -->` markers so template-author content outside the block is preserved across refreshes.
+- **Project indicator in Chat** — folder chip in `SessionInfoBar` and `Chat · <ProjectName>` in the nav title when you're in a project-scoped chat. Resumed sessions keep the indicator by looking up the attribution sidecar at resume time.
+- **Window-layout cleanup** — switching to Chat or a Sessions tab no longer grows the window past the screen. `.windowResizability(.contentMinSize)` + targeted `idealHeight` caps keep the window's floor at a sensible content minimum while letting users freely drag larger or smaller.
+
+See the full [v2.3.0 release notes](https://github.com/awizemann/scarf/releases/tag/v2.3.0) and the [Project Templates wiki page](https://github.com/awizemann/scarf/wiki/Project-Templates).
+
+### Previously, 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 **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`.
+- **Public template catalog** — [awizemann.github.io/scarf/templates/](https://awizemann.github.io/scarf/templates/) with live dashboard previews + schema rendering. CI-enforced Python validator mirrors the Swift-side invariants on every PR.
+- **Safe-by-design** — skills namespaced, cron jobs tagged and paused-on-install, lock-file-driven uninstall, exports carry schema but never values.

+## 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

+## 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.

+## What's New in 2.2.1
+
+A patch release covering Template Configuration rendering fixes reported against v2.2.0, plus a new catalog template that packages a Hermes skill for scaffolding new Scarf projects.
+
+### Configuration sheet — no more clipping
+
+Two independent rendering fixes to the post-install Configuration editor and the install-flow Configure step:
+
+- **Enum fields with long option labels.** An enum with three or four options whose labels exceeded ~20 characters — e.g. a Claude-model picker with labels like *"Claude Opus 4 (Recommended - Most Capable)"* — rendered as a segmented picker that sized to the intrinsic width of all labels concatenated. On macOS, `.pickerStyle(.segmented)` refuses to respect offered width, refuses to wrap, refuses to truncate. The result was a ~650pt picker that overflowed the sheet's 560pt viewport and clipped the entire form on both sides. Enum fields now always render as a dropdown Menu picker, which surfaces long labels in the popup list and respects the parent's offered width regardless of option count or label length.
+- **Descriptions with unbreakable content.** Field descriptions rendered via inline AttributedString markdown can contain tokens SwiftUI's `Text` refuses to break mid-token (raw URLs, long paths). Added `.frame(maxWidth: .infinity, alignment: .leading)` on the sheet's inner VStack and on each field row as a secondary constraint, so description text wraps at whitespace boundaries instead of expanding the sheet width. Applied the same modifier to `TemplateInstallSheet`'s main preview VStack for symmetry — installs with README blocks or cron prompts containing long URLs now wrap cleanly too.
+
+### New catalog entry — `awizemann/template-author`
+
+A `.scarftemplate` whose only content is a Hermes skill (`scarf-template-author`) plus a minimal dashboard that points users at it. Installing the template drops the skill at `~/.hermes/skills/templates/awizemann-template-author/scarf-template-author/SKILL.md`, discoverable by Claude Code, Cursor, Codex, Aider, and every other agent that reads the standard `~/.hermes/skills/` directory.
+
+The skill teaches agents how to scaffold a new Scarf-compatible project through a short interview — purpose, data source, cadence, widgets, config, secrets — then write `<project>/.scarf/dashboard.json`, `<project>/.scarf/manifest.json`, `<project>/AGENTS.md`, and `<project>/README.md`. Scaffolded projects are usable locally and cleanly exportable as `.scarftemplate` bundles via Scarf's Export flow later. [Catalog detail page →](https://awizemann.github.io/scarf/templates/awizemann-template-author/)
+
+v1 is fully conversational / blank-slate. Pre-baked archetypes (monitor, dev-dashboard, personal-log) are deferred to a future release pending real usage data.
+
+### Authoring guidance — SKILL.md
+
+The `scarf-template-author` skill now tells scaffolding agents to prefer markdown link syntax (`[label](https://…)`) over raw URLs in schema field descriptions. Raw URLs work now (v2.2.1's description wrap fix above handles them gracefully), but `[Anthropic console](https://console.anthropic.com)` reads cleaner in the form than a dumped URL. Same rule extended to long paths or other unbreakable strings — wrap in inline code if they have to appear verbatim, prefer markdown links otherwise.
+
+### Under the hood
+
+- **`scripts/catalog.sh publish` fix.** The pre-flight `need_ghpages` check tested `[[ -d "$GHPAGES_DIR/.git" ]]` — "is `.git` a directory?" — which is true for a regular clone but false for a `git worktree add` worktree (where `.git` is a pointer file). `release.sh` creates and leaves the gh-pages worktree around, so after any release the subsequent catalog-publish call was rejected with a misleading "run `git worktree add`" error on a worktree that was already there and valid. Switched to `-e` (exists, either file or directory). Unblocks publishing the catalog immediately after a release.
+
+### Migrating from 2.2.0
+
+Sparkle will offer the update automatically. No config migration needed. Existing template installs are untouched.
+
+If you've already installed `awizemann/template-author` from a pre-release build, no action needed — the catalog and bundle content are forward-compatible.

Folders, rename + archive + search + keyboard jumps, a per-project Sessions tab with a one-click New Chat button, and — the big architectural piece — every project-scoped chat now automatically carries Scarf-managed context into the agent itself, so the agent knows what project it's operating in without any user prompting.
+
+### Projects sidebar grows up
+
+- **Folders.** Group related projects with folders. Right-click any project → *Move to Folder…* — pick an existing folder or create a new one on the fly. Folders are soft: any folder name that isn't referenced by at least one project just disappears, so there's no "empty folder" state to clean up.
+- **Rename** a project from the context menu. Preserves everything else — the path, folder assignment, archive flag, and any running cron attribution stay intact. Rejects duplicate names + empty input with an inline warning.
+- **Archive / Unarchive.** Hide projects you don't actively use without deleting anything. The sidebar's bottom bar gains a Show Archived toggle so they're one click away when you need them.
+- **Search.** ⌘F focuses a filter field at the top of the sidebar. Fuzzy-matches on name, path, and folder label, live as you type.
+- **Keyboard jumps.** ⌘1 through ⌘9 jump to the first nine top-level projects. Pairs cleanly with Scarf's existing window-level shortcuts.
+
+Registry migration is non-destructive — `~/.hermes/scarf/projects.json` gains two optional fields (`folder`, `archived`), and a file written by v2.3 is still parseable by v2.2.1 (unknown-keys are ignored), so downgrade works if you ever need it.
+
+### Per-project Sessions tab
+
+Every project now has a **Sessions** tab alongside Dashboard and Site. It shows chats attributed to this specific project — the sidecar at `~/.hermes/scarf/session_project_map.json` maintains the session-to-project mapping (Hermes's `state.db` has no column for this, so Scarf owns the record).
+
+- **New Chat** — spawns `hermes acp` with the project's directory as the session's working directory, attributes the resulting session to the project, and takes you straight into the chat view.
+- **Click any listed session to resume it** in the Chat tab; the project indicator comes along automatically.
+- Forward-only attribution: sessions you've already started via the CLI or via the global Chat sidebar section continue to live in the global Sessions view unchanged; they simply aren't attributed to any project.
+
+File descriptors are released cleanly on tab-disappear, matching Scarf's other Hermes-DB-reading VMs.
+
+### Agent context injection via AGENTS.md
+
+The architectural headline of this release. Hermes has no native "project" concept and ACP's wire protocol drops extra session params. But Hermes DOES auto-read `AGENTS.md` from the session's cwd at startup (priority: `.hermes.md` → `HERMES.md` → `AGENTS.md` → `CLAUDE.md` → `.cursorrules`, first match wins, 20KB cap). So Scarf leans on that.
+
+Every time you start a project-scoped chat, Scarf writes a managed block into `<project>/AGENTS.md`:
+
+```
+<!-- scarf-project:begin -->
+## Scarf project context
+
+You are operating inside a Scarf project named "<Project Name>". …
+
+- Project directory: …
+- Dashboard: …
+- Template: <id> v<version>
+- Configuration fields: field_a, api_token (secret — name only, value stored in Keychain)
+- Registered cron jobs: [tmpl:<id>] <name> — schedule …
+…
+<!-- scarf-project:end -->
+```
+
+Ask a fresh chat *"what project am I in?"* and the agent answers with the project name, dashboard path, template id, and current cron schedule — pulled from the block Hermes injected into its system prompt automatically.
+
+**Invariants the block guarantees:**
+
+- **Secret-safe.** Surfaces config field *names* with type hints; never values. A project whose config.json has Keychain-ref URIs renders the fields as `api_token (secret — name only, value stored in Keychain)`. Keychain URIs and plaintext values never appear in the block. Locked in by an explicit test (`refreshListsFieldNamesNotValues`).
+- **Idempotent.** Two consecutive refreshes with unchanged state produce byte-identical output. The write is skipped entirely when no delta — no unnecessary file-watcher churn.
+- **Bounded.** Everything outside the `<!-- scarf-project -->` markers is preserved across every refresh. Template-author AGENTS.md content lives safely below the block; hand-edits are never clobbered.
+- **Non-fatal.** A failed block refresh doesn't block the chat from starting — logged + the session proceeds without the extra context.
+- **Bare-project friendly.** Projects without an AGENTS.md (plain directories added via the + button) get one created with just the block. Agent awareness works even without template scaffolding.
+
+**Template-author contract:** leave the `<!-- scarf-project -->` region alone in your bundled `AGENTS.md`. Put template-specific instructions below it so they're preserved across refreshes. The `scarf-template-author` scaffolding skill already teaches this pattern to future agents doing project scaffolding.
+
+**Known caveat:** if any parent directory of your project contains a `.hermes.md` or `HERMES.md`, that file takes priority over the project's AGENTS.md in Hermes's discovery order — the Scarf block gets shadowed. No fix in 2.3 — planned for 2.4 pending design input on handling authored `.hermes.md` files.
+
+### Chat UI — project awareness everywhere
+
+Once the cwd, attribution, and AGENTS.md pieces land, the UI follows:
+
+- **Folder chip in `SessionInfoBar`** at the start of the bar (before the working dot + title) shows the active project name with a folder icon.
+- **Navigation title** reads `Chat · <ProjectName>` when scoped, plain `Chat` otherwise — macOS `Subject — Detail` convention.
+- **Resumed sessions keep the indicator.** Whether you click a session in the project's Sessions tab or come in from a future deep-link, the attribution is looked up at resume time and the chip renders from the same state.
+
+### Window-layout fixes
+
+A pre-existing issue — untracked until v2.3's heavier Chat/Sessions content exposed it — where the window grew past the screen when you switched to content-heavy sections. Fixed by:
+
+- Setting `WindowGroup.windowResizability(.contentMinSize)` so the window's floor (not ceiling) is derived from content.
+- Capping `idealHeight` on `RichChatView` and `ProjectSessionsView` so their plain-VStack children (deliberate choice to dodge a LazyVStack whitespace bug) don't report screen-exceeding ideals upward through `NavigationSplitView.detail`.
+
+Window now stays at a user-draggable size and persists across section switches.
+
+### Under the hood
+
+- New models: `SessionProjectMap` — `~/.hermes/scarf/session_project_map.json` serialization (`SessionAttributionService` manages it).
+- New services: `SessionAttributionService` (reads + writes the sidecar), `ProjectAgentContextService` (writes the AGENTS.md marker block, tests cover prepend/replace/idempotency/secret-redaction).
+- New view models: `ProjectSessionsViewModel` (per-project session list with attribution filter), `ChatViewModel` gains `currentProjectPath` + `currentProjectName`.
+- `HermesFileWatcher` now watches the attribution sidecar — file-system events propagate through the VMs as they do for every other Scarf-written file.
+- `ProjectsViewModel` gains `moveProject / renameProject / archiveProject / unarchiveProject / folders` — rename preserves selection; archive clears it; reorders driven by `localizedCaseInsensitiveCompare` for locale-aware ordering.
+- **22 new Swift tests** across `ProjectRegistryMigrationTests`, `ProjectsViewModelTests`, `SessionAttributionServiceTests`, `ProjectAgentContextServiceTests`. Total: 93 tests.
+
+### Icon tweak
+
+App icon files renamed from iOS-template suffixes to macOS-native filenames + paired `Contents.json` update. Pure naming; no visual change at any rendered size.
+
+### Migrating from 2.2.x
+
+Sparkle will offer the update automatically. No config migration needed. Existing template installs are untouched — the v2.3 additions (folders, archive, sidecar) are purely additive; a v2.2.1 projects.json loads cleanly.
+
+If you had any chat sessions attributed to projects in a pre-release v2.3 build, the forward-only attribution model means those sidecar entries surface correctly in the new Sessions tab on first launch.
+
+### Documentation
+
+- **[Project Templates wiki page](https://github.com/awizemann/scarf/wiki/Project-Templates)** — gained a "How the agent sees the project" section covering the AGENTS.md injection pattern.
+- **Root `CLAUDE.md`** — new subsection "Project-scoped chat + Scarf-managed AGENTS.md context (v2.3)" under Project Templates, covering the sidecar, the marker contract, invariants, and the template-author contract.
+- **`scarf-template-author` skill** — pitfall bullet added so future scaffolding agents preserve the marker region when authoring new templates.
+
+### Thanks
+
+Thanks to the users who exercised this release through several layout iterations, caught the `fetchSessions` short-circuit on a fresh VM, and pushed on the "agent doesn't know what project it's in" question until the AGENTS.md mechanism clicked. Several of these fixes are small on their own but add up to a much tighter per-project workflow.

+# 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.

+
+## Projects System Evolution (post-v2.2.1)
+
+A parallel backlog specific to the Projects feature. Ordered by dependency: organization first, then per-project attribution via sidecar, then observability built on that attribution, then polish, then platform bets.
+
+### Shipping in v2.3 (planned — plan file at `~/.claude/plans/`)
+
+- **Folder hierarchy in the sidebar.** `ProjectEntry` gains optional `folder: String?`. `DisclosureGroup`-based sidebar.
+- **Rename + archive + search.** Registry verbs + a fuzzy ⌘F search + soft-archive (`archived: Bool?`) with Show/Hide toggle.
+- **⌘1–⌘9 project jumps.**
+- **Per-project Sessions tab** alongside Dashboard / Site. Filters the global sessions list by a new `~/.hermes/scarf/session_project_map.json` sidecar that Scarf populates when it starts a chat with a project context.
+- **New Chat button** on the Sessions tab — spawns `hermes acp` with `cwd = project.path` and attributes the resulting session in the sidecar.
+
+### v2.4+ — per-project observability
+
+Depends on v2.3's sidecar being stable. All features below are "filter the existing data by the sidecar's project mapping."
+
+- **Per-project activity feed.** Extend `ActivityViewModel` with a `projectPath` filter that maps through the sidecar. Dashboard widget type `recent-activity`.
+- **Per-project token / cost rollup.** `InsightsViewModel.computeAggregates()` already sums over sessions; add a project filter. Widget binding `project.tokens` exposes it to agent-driven dashboards.
+- **Per-project cron-job filter.** Cron sidebar gains a project dropdown. Template-installed jobs already carry `[tmpl:<id>]` prefixes; match against installed template manifests to attribute.
+- **Desktop notifications for cron completion.** When a project-attributed cron job finishes (success or failure), fire a `UNUserNotification`. Per-project mute.
+
+### v2.5+ — platform bets
+
+Bigger investments with longer arcs.
+
+- **Hermes upstream: `sessions.cwd` column.** Propose adding a nullable `cwd` (or `workspace_id`) column to Hermes's sessions table, populated on session create. Scarf would prefer the canonical column when available and fall back to the sidecar for pre-upgrade sessions. Requires coordinated Hermes release; filed under platform bets because it cuts the sidecar's blind spot (CLI-started sessions never enter the sidecar today).
+- **Per-project memory slice.** Hermes reads `MEMORY.md` from a known path. Explore whether Scarf can spawn `hermes acp` with an overridden memory path (per-project `<project>/.scarf/MEMORY.md`) so projects get isolated context. Needs a Hermes-side env var or flag.
+- **Per-project skills namespace.** Today user-authored skills are flat under `~/.hermes/skills/`. A `~/.hermes/skills/project/<slug>/` namespace parallel to the existing `templates/` namespace would let users install skills *into* a project without a template. Uninstall = drop the folder.
+- **Cross-project meta-dashboards.** A portfolio view that aggregates widgets from multiple projects — total token spend, combined activity feed, project-health matrix. Useful at 20+ projects.
+- **Project backup / restore.** One-click zip of `<project>/` + sidecar entries + related Keychain secrets, restorable on another machine. Richer than the existing Export flow (which carries the template shape only).
+
+### Continuous — UX polish
+
+Small, shippable at any time. Each is a half-day-to-one-day item.
+
+- **Drag-and-drop to reorder** projects within a folder and between folders. Would be the first use of `.onDrag`/`.onDrop` in the codebase; establishes the pattern.
+- **Tags as a secondary axis.** Keep folders as primary, add multi-valued string tags + filter chips at the sidebar top. Decide only if folders feel insufficient after v2.3 lands.
+- **Favorites / pin** — bubble a project to the top of its folder.
+- **Recent projects collection** — auto-populated "Recents" row at the top of the sidebar.
+- **Color labels or SF Symbol icons** per project (Finder-tag-style).
+- **Project dashboard starter templates** — "blank", "monitor", "feed", "timeline" shapes when creating a bare project (distinct from `.scarftemplate` sharing flow).
+- **Opportunistic session backfill.** When Scarf loads any session that isn't in the sidecar, peek at first tool call's `working_directory` or `cwd` hint; if it matches a registered project path, write a sidecar entry. Heuristic, not perfect — useful as an "it just works" improvement after v2.3 ships.
+
+### Research / verification gaps
+
+Noted during v2.3 planning; chase when relevant:
+
+- `DisclosureGroup` inside `List(.sidebar)` on macOS — occasional animation glitches with many-rows-expanding. Early prototype will confirm before full commit.
+- Concurrent sidecar writers from multiple Scarf windows on the same `~/.hermes` — atomic replace handles per-write; reload behavior may lag. Acceptable; revisit if users report stale attribution.
+- Do Hermes sessions ever persist `cwd` anywhere in `state.db` today that we've missed? If so, we can skip the sidecar and use it directly. Worth a one-hour investigation before starting v2.4 observability work.

+/// Writes a Scarf-managed marker block into `<project>/AGENTS.md` so
+/// that Hermes — which auto-reads `AGENTS.md` from the session's cwd
+/// at startup — has consistent project identity and metadata in every
+/// project-scoped chat.
+///
+/// **Why this exists.** Hermes has no native "project" concept and ACP
+/// passes only `(cwd, mcpServers)` at session create — extra params
+/// are silently dropped on Hermes's side. The documented hook for
+/// giving the agent context when cwd is set programmatically is the
+/// auto-load of `AGENTS.md` (or `.hermes.md` / `CLAUDE.md` /
+/// `.cursorrules`, in that priority) from the cwd. Scarf owns a
+/// managed region of the project's AGENTS.md; template-author content
+/// lives outside that region and is preserved.
+///
+/// **Marker contract.** The region sits between:
+///
+/// ```
+/// <!-- scarf-project:begin -->
+/// …Scarf-managed content…
+/// <!-- scarf-project:end -->
+/// ```
+///
+/// Same pattern as the v2.2 memory-block appendix — bounded, self-
+/// declaring, safe to re-generate. Everything outside the markers is
+/// left byte-identical across refreshes.
+///
+/// **Secret-safe.** The block surfaces field NAMES from `config.json`
+/// (via the cached manifest's schema) but never VALUES. A rendered
+/// block contains no secrets even for a project whose config.json
+/// has Keychain-ref URIs.
+///
+/// **Refresh timing.** `ChatViewModel.startACPSession(resume:projectPath:)`
+/// calls `refresh(for:)` immediately before Hermes opens the session.
+/// Hermes reads AGENTS.md during session boot, so the marker block
+/// must have landed on disk first. Non-blocking on failure — a

+///   `template.json` and a copy is stashed at `<project>/.scarf/manifest.json`
+///   at install time so the post-install editor works offline. This
+///   service treats the schema as read-only input; `validateSchema`
+///   checks structural invariants and is called by
+///   `ProjectTemplateService` during install-plan building.
+/// - **Value storage.** Non-secret values live inline in `config.json`;
+///   secret values are Keychain references of the form
+///   `"keychain://<service>/<account>"`. The service owns both halves
+///   of that storage — callers never open `config.json` or touch the
+///   Keychain directly.
+/// - **Remote readiness.** All file I/O goes through
+///   `ServerContext.makeTransport()` so when `ProjectTemplateInstaller`
+///   eventually supports remote contexts, the config store comes along
+///   for the ride. Keychain access stays local (it's a macOS-side thing
+///   by definition — agents on remote Hermes installs would fetch
+///   values via Scarf's channel, same as today).
