docs: sync READMEs with 26.15 HTTPS opt-in + boot-USB filter

- README roadmap: Local HTTPS Phase 1 entry now reflects the 26.15
  opt-in model (default off, toggle in /settings) instead of the
  26.4 auto-trust story.
- README + iso/README: boot-USB filtering is no longer a TODO; both
  files now describe the implemented `findmnt`/`PKNAME` behaviour.
- iso/README rough edges: drop the boot-USB bullet (closed) and
  re-word the wizard-still-HTTP-only bullet to match the 26.15 toggle
  flow (it was a stale dup of the same line under it).

 ## [Unreleased]
 
+## [26.15-alpha] - 2026-04-21
+
+### Fixed
+
+- **HTTPS is now opt-in; fresh installs no longer hit unbypassable
+  SEC_ERROR_BAD_SIGNATURE.** Every version since 26.5 shipped a
+  Caddyfile with a `__FURTKA_HOSTNAME__.local { tls internal }` site
+  block, so Caddy auto-generated a self-signed root CA + intermediate
+  + leaf on first boot. That worked for first-time-ever users, but
+  every reinstall (or second Furtka box on the same LAN) produced a
+  new CA with the **same intermediate CN** (`Caddy Local Authority -
+  ECC Intermediate` — Caddy hardcodes it). Any browser that had ever
+  trusted an earlier Furtka CA got a cached intermediate with
+  mismatched keys, then Firefox's cert lookup substituted the cached
+  intermediate when validating the new box's leaf → the signature
+  check failed → `SEC_ERROR_BAD_SIGNATURE`, which Firefox has no
+  "Advanced → Accept Risk" bypass for.
+  - Removed the hostname site block from the default Caddyfile.
+    Fresh installs serve `:80` only; visiting `https://furtka.local`
+    now yields a clean connection-refused instead of the crypto
+    fault.
+  - Added top-level `import /etc/caddy/furtka-https.d/*.caddyfile`.
+    The `/settings` HTTPS toggle (via `furtka.https.set_force_https`)
+    now writes TWO snippets atomically — the top-level hostname +
+    `tls internal` block (enables `:443`) and the `:80`-scoped
+    redirect (forces HTTP → HTTPS) — and removes both on disable.
+    Caddy reloads after the pair-swap; failure rolls both back.
+  - Webinstaller creates `/etc/caddy/furtka-https.d/` during
+    post-install alongside the existing `furtka.d/`.
+  - `updater._refresh_caddyfile` runs a 26.14 → 26.15 migration: if
+    the box already had the redirect snippet on disk (user had
+    explicitly enabled "Force HTTPS" under the old regime), the
+    migration also writes the new listener snippet so HTTPS keeps
+    working across the upgrade.
+- **`status.force_https` now reads the listener snippet, not the
+  redirect snippet.** A lone redirect without a `:443` listener
+  wouldn't actually serve HTTPS, so the listener file is the
+  authoritative "HTTPS is on" signal. The UI on `/settings` sees the
+  correct state as a result.
+
+Known remaining UX wart: a browser that trusted a previous Furtka box
+still sees `BAD_SIGNATURE` when visiting this box's `https://` after
+enabling HTTPS here — the fixed intermediate CN is a Caddy-side
+limitation we can't fix from Furtka. Fresh installs on a browser that
+never visited another Furtka box work correctly. Workaround:
+`about:networking#sts` → Forget → clear `cert9.db`.
+
+## [26.14-alpha] - 2026-04-21
+
+### Fixed
+
+- **Landing page and `/settings/` were silently bypassing the auth
+  guard.** Since 26.11 shipped login, the Caddyfile only
+  reverse-proxied `/api/*`, `/apps*`, `/login*`, and `/logout*` to
+  Python. Everything else — including `/` and `/settings/` — fell
+  through to Caddy's catch-all `file_server` and was served straight
+  from `assets/www/` without ever hitting the session check. The
+  effect: a LAN visitor saw the box's hostname, IP, Furtka version,
+  and the buttons for Update-now / Reboot / HTTPS-toggle. The API
+  calls those buttons fired were all 401-auth-gated so actions didn't
+  land, but the information leak and the "looks open" UX was a real
+  bug. Caught in the 26.13 SSH test session when the user noticed
+  Logout only showed up on `/apps`. Now Caddy routes `/` and
+  `/settings*` through Python; a new `_serve_static_www` handler
+  checks the session cookie, redirects to `/login` if unauthed, and
+  reads the HTML from `assets/www/` otherwise. Catch-all still
+  serves `/style.css`, `/rootCA.crt`, and the runtime JSON files
+  publicly — those don't need auth.
+- **Logout link now shows on every authed page, not just `/apps`.**
+  The static HTML for `/` and `/settings/` maintained their own nav
+  separate from `_HTML` in `api.py`, so they never got the Logout
+  entry when it was added in 26.11. Both nav bars now include it
+  plus an inline `doLogout()` that POSTs `/logout` and bounces to
+  `/login`, matching the pattern in `_HTML`.
+
+## [26.13-alpha] - 2026-04-21
+
+### Fixed
+
+- **Upgrade path from pre-auth releases actually works.** 26.11-alpha
+  introduced `from werkzeug.security import ...` in `furtka/auth.py`,
+  but werkzeug isn't installed on the target system — core runs as
+  system Python with stdlib only, and `flask>=3.0` in `pyproject.toml`
+  is never pip-installed on the box. Fresh boxes from the 26.11/26.12
+  ISO without a manually-installed werkzeug crashed on import; boxes
+  upgrading from pre-26.11 got double-broken by that plus the health
+  check below. Replaced the werkzeug dependency with a stdlib-only
+  `furtka/passwd.py` that uses `hashlib.pbkdf2_hmac` for new hashes
+  and parses werkzeug's `scrypt:N:r:p$salt$hex` format for backward
+  compatibility — existing `users.json` files created on the rare
+  boxes that did have werkzeug keep working after this upgrade, no
+  re-setup needed. `from werkzeug.security import ...` is gone from
+  the import chain entirely; `pyproject.toml`'s flask dep stays only
+  for the live-ISO webinstaller.
+- **Self-update no longer auto-rolls-back when crossing the auth
+  boundary.** `updater._health_check` pinged `/api/apps` and demanded
+  a 200, which meant every 26.10 → 26.11+ upgrade hit the post-restart
+  check, got a 401 (auth guard), and treated that as "server dead"
+  → rollback. Now any 2xx–4xx response counts as "server alive"; only
+  connection-level failures or 5xx fail the check. 5xx still fails
+  rollback because that means the new process is up but broken.
+- **Install lock closes its race window.** `POST /api/apps/install`
+  used to release the fcntl lock immediately after the sync
+  pre-validation so the systemd-run child could re-acquire it —
+  leaving a tiny gap where a second POST could slip in, pass the lock
+  check, and return 202. Both child processes would start, one would
+  win the in-child lock, the other would die silently. Now the API
+  also reads `install-state.json` and refuses with 409 if the stage
+  is non-terminal (`pulling_image`, `creating_volumes`,
+  `starting_container`). The fcntl lock stays as belt-and-suspenders.
+
+## [26.12-alpha] - 2026-04-21
+
+### Changed
+
+- **App-Install geht async mit Live-Progress.** `POST /api/apps/install`
+  returnt jetzt `202 Accepted` nach der synchronen Pre-Validation
+  (Source auflösen, Files kopieren, `.env` schreiben, Placeholder- und
+  Path-Checks). Den eigentlichen Docker-Teil (`compose pull` → volumes
+  → `compose up`) dispatched der Handler als `systemd-run
+  --unit=furtka-install-<app>` Hintergrund-Job, der seine Phase in
+  `/var/lib/furtka/install-state.json` schreibt. Neues
+  `GET /api/apps/install/status` für UI-Polling. Das Install-Modal
+  zeigt jetzt live "Image wird heruntergeladen…" →
+  "Speicherbereiche werden erstellt…" → "Container wird gestartet…"
+  statt ~30 Sekunden totem "Installing…". Muster 1:1 parallel zu
+  `/api/catalog/sync/apply` und `/api/furtka/update/apply`. Neue CLI-
+  Subcommand `furtka app install-bg <name>` (intern, von der API
+  aufgerufen); `furtka app install` für Terminal-User bleibt synchron.
+  Die Reinstall-Taste in der App-Liste pollt ebenfalls den
+  Install-Status und spiegelt die Phase im Button-Text.
+
+## [26.11-alpha] - 2026-04-21
+
+### Added
+
+- **Login-auth for the Furtka web UI.** Every `/apps`, `/api/*`, `/`,
+  and `/settings/` route now requires a signed-in session. New
+  `/login` page serves a username/password form; `POST /login`
+  validates against `/var/lib/furtka/users.json` (werkzeug PBKDF2-
+  hashed), sets a `furtka_session` cookie (`HttpOnly`, `SameSite=
+  Strict`, 7-day TTL), and redirects to `/apps`. `POST /logout`
+  revokes the server-side session and clears the cookie.
+  Unauthenticated HTML requests get a 302 to `/login`; unauthenticated
+  API requests get 401 JSON. The old "No authentication on this UI
+  yet" banner is gone; the `/apps` header picks up a `Logout` link
+  instead.
+- **First-run setup fallback for upgrade-path boxes.** Boxes
+  upgrading from 26.10-alpha have no `users.json` yet — on the first
+  visit `/login` renders a setup form (username + password +
+  password-confirm) that creates the admin record on submit. Fresh
+  installs skip this: the webinstaller writes `users.json` during
+  the chroot post-install step using the step-1 password, so the
+  first browser visit after boot goes straight to the login form.
+- **Caddy proxy routes `/login` and `/logout`.** `assets/Caddyfile`
+  gets two new `handle` blocks in the shared `(furtka_routes)`
+  snippet so both the `:80` block and the `hostname.local, hostname`
+  HTTPS block forward the auth endpoints to the stdlib server on
+  `127.0.0.1:7000`. Without this Caddy would serve a 404 from the
+  static file server.
+
+### Fixed
+
+- `tests/test_installer.py` ruff-format nit — the 26.10-alpha
+  release commit had a misformatted list literal that failed
+  `ruff format --check`. Caught when the Release page on Forgejo
+  showed a red CI badge for the tag.
+- `pyproject.toml` version string bumped from the stale 26.8-alpha
+  to 26.11-alpha. Release pipeline uses `GITHUB_REF_NAME` as source
+  of truth for the artefact name, but having the two agree matters
+  for local dev runs that read `pyproject.toml`.
+
+## [26.10-alpha] - 2026-04-21
+
+### Added
+
+- **Remove-USB-stick hint on the installer's post-install screen.**
+  `webinstaller/templates/install/rebooting.html` now shows a bold
+  "Remove the USB stick now" line before the reboot, plus a muted
+  fallback explaining the BIOS boot-menu keys (F11/F12/Esc) if the
+  machine boots back into the installer anyway. Caught on the first
+  bare-metal test (Medion i5-4gen, 2026-04-21) where the box didn't
+  boot the installed system without manual BIOS-order changes.
+- **New `path` setting type for app manifests.** Apps can now declare a
+  setting with `"type": "path"` whose value is an absolute filesystem
+  path on the host; docker-compose bind-mounts it via the usual `.env`
+  substitution (`${MEDIA_PATH}:/media`). Unlocks media/data-heavy apps
+  (Jellyfin, later Paperless/Nextcloud/Immich) where the user points at
+  an existing folder instead of copying everything into a Docker
+  volume. The install form renders path settings as a plain text input
+  with a `/mnt/…` placeholder hint.
+- **Server-side path validation.** Both `install_from()` and
+  `update_env()` refuse values that aren't absolute, don't exist,
+  aren't directories, or resolve (after `Path.resolve()`) into a
+  system-path deny-list (`/`, `/etc`, `/root`, `/boot`, `/proc`,
+  `/sys`, `/dev`, `/bin`, `/sbin`, `/usr/bin`, `/usr/sbin`,
+  `/var/lib/furtka`). Catches `/mnt/../etc`-style traversal too. Error
+  messages surface in the existing install/edit modal error line.
+
+## [26.9-alpha] - 2026-04-21
+
+### Fixed
+
+- Landing-page app tiles with an `open_url` now open in a new tab
+  (`target="_blank" rel="noopener"`), matching the Open button
+  behaviour on `/apps`. Without this, clicking "Uptime Kuma" on the
+  home screen replaced Furtka itself with the Kuma admin page.
+  Internal links (the `Manage →` fallback for apps without an
+  `open_url`) still open in the same tab.
+- `scripts/publish-release.sh` no longer fails the whole release when
+  the ISO upload hits a Forgejo proxy 504. The core tarball + sha256 +
+  release.json (which running boxes need for self-update) are uploaded
+  first and the ISO is attempted last as a best-effort; a 504 now logs
+  a warning and exits 0 so the release page still publishes. Surfaced
+  by the 26.8-alpha cut: the tarball landed but the ~1 GB ISO upload
+  timed out at the Forgejo reverse proxy.
+
+### Changed
+
+- `furtka app list --json` now mirrors `/api/apps` field-for-field —
+  previously the CLI emitted a slim projection missing
+  `description_long`, `open_url`, and `settings`. Anyone piping the
+  CLI output into jq for automation was seeing an incomplete view.
+
+## [26.8-alpha] - 2026-04-20
+
+### Added
+
+- **Live-installer ISO attached to the Forgejo release page.** `.forgejo/workflows/release.yml` moves to the self-hosted runner, builds both the self-update tarball and the ISO, and `scripts/publish-release.sh` uploads the ISO as a fourth release asset (`furtka-<version>.iso`) alongside the existing tarball + sha256 + release.json. Fresh-install users can now grab the ISO from the release page instead of hunting through `build-iso.yml` artifact retention windows. ISO build step is `continue-on-error` so an ISO flake doesn't hold back the core tarball that running boxes need for self-update.
+- **Reboot + Shut down buttons on `/settings`.** Replaces the two "Coming next" placeholders with real actions backed by `POST /api/furtka/power` (`{"action": "reboot" | "poweroff"}`). Handler kicks a delayed `systemd-run --on-active=3s systemctl {reboot|poweroff}` so the HTTP response reaches the browser before the kernel loses network. Each button opens a native confirm dialog first (reboot: "back in ~30 s", shut down: "need to press the physical power button"), then the UI swaps to a status line and — after a reboot — polls `/furtka.json` until the box is back, reloading the page automatically. No auth (same posture as install/remove).
+- **Manifest `open_url` field + Open button in `/apps` and on the landing page.** Apps declare a URL template (e.g. `smb://{host}/files` for fileshare, `http://{host}:3001/` for Uptime Kuma); the UI substitutes `{host}` with the current browser's hostname at render time so the link follows however the user reached Furtka (furtka.local, raw IP, a future reverse-proxy hostname). The landing page's hardcoded `if app.name === 'fileshare'` special-case is gone — any app with an `open_url` in its manifest now gets a proper "Open" link. The core seed `apps/fileshare/manifest.json` bumps to v0.1.2 to carry it.
+
+### Changed
+
+- `.btn` CSS class introduced so an `<a>` rendered-as-button lines up with its `<button>` siblings in `.buttons`. Needed because "Open" is a real link (middle-click, copy URL, screen readers) and HTML doesn't let `<button>` carry `href`.
+
+### Notes
+
+- `26.7-alpha` was tagged but never published — the tag push didn't trigger `release.yml` (Forgejo race with the concurrent main push). `26.8-alpha` supersedes it and carries the same content plus power actions.

 - [ ] Installer wizard screens S3–S7 — per-device purpose, network, domain, SSL, diagnostic. S5/S6 blocked on managed-gateway DNS infra not yet built.
 - [ ] Local HTTPS Phase 2 — dedicated local CA (not Caddy's `tls internal`), streamlined one-click install across Win/Mac/Linux/Android, and HTTPS on the live-installer wizard (`https://proksi.local:5000`).

@@ -47,10 +47,42 @@ Rules enforced by `furtka/manifest.py`:
 - `volumes` — short names, strings. Namespaced to `furtka_<app>_<short>` at runtime.
 - `ports` — integers. Informational only; compose owns the actual port binding.
 - `settings[].name` — must match `^[A-Z_][A-Z0-9_]*$`. This name becomes both the env-var key and the form-field ID.
-- `settings[].type` — one of `text`, `password`, `number`.
+- `settings[].type` — one of `text`, `password`, `number`, `path`.
 - `settings[].required` — if true, the install refuses when the value is empty.
 - `settings[].default` — optional string. Used to pre-fill the form and the bootstrapped `.env`.
 
+### Path-type settings (host bind mounts)
+
+Use `"type": "path"` when the app should point at an existing folder on the host — media libraries, document archives, photo backups. The value is written to `.env` like any other setting, and compose consumes it via `${VAR}` substitution as a bind mount.
+
+```json
+{
+  "name": "MEDIA_PATH",
+  "label": "Medienordner",
+  "description": "Absoluter Pfad zu deinem Medien-Ordner, z.B. /mnt/media.",
+  "type": "path",
+  "required": true
+}
+```
+
+```yaml
+services:
+  app:
+    volumes:
+      - ${MEDIA_PATH}:/media:ro
+```
+
+The installer (`install_from` and `update_env`) refuses values that:
+
+- aren't absolute (must start with `/`),
+- don't exist on the host,
+- aren't directories,
+- resolve (after `Path.resolve()`) into a system-path deny-list: `/`, `/etc`, `/root`, `/boot`, `/proc`, `/sys`, `/dev`, `/bin`, `/sbin`, `/usr/bin`, `/usr/sbin`, `/var/lib/furtka`.
+
+Traversal like `/mnt/../etc` is caught too — the deny-list check runs on the resolved path.
+
+Path settings sit alongside manifest-declared volumes. Use `manifest.volumes` for internal state the app owns (databases, caches, config), and path settings for user data the container should mount and — usually — read without owning. Mounting read-only (`:ro`) is a good default for data the app only consumes.
+

 - File extension is `.yaml`. The compose runner hardcodes this — `.yml` will not be found.

+One admin, one password. Passwords are PBKDF2-SHA256 hashed via
+``furtka.passwd`` (stdlib-only — hashlib.pbkdf2_hmac / hashlib.scrypt),
+stored in /var/lib/furtka/users.json with mode 0600. Sessions live in
+memory — a systemctl restart logs everyone out again, which is fine
+for an alpha single-user box. The ``LoginAttempts`` store in this
+module rate-limits failed logins per (username, IP) and is also
+in-memory; a restart clears a stuck lockout.
+
+On upgrade from pre-auth Furtka the users.json file does not exist
+yet; the api's GET /login detects this via ``setup_needed()`` and
+renders a first-run form that POSTs to /login as if it were a setup
+submit. Fresh installs get the file pre-populated by the webinstaller
+so the setup step is skipped.
+
+Hash format is compatible with werkzeug.security — 26.11 / 26.12 boxes

+cert on :443. Any browser that had ever trusted a previous Furtka
+box's local CA rejected the new cert with an unbypassable
+SEC_ERROR_BAD_SIGNATURE — Firefox in particular has no "Advanced →

+"""Background job for app installs — progress-visible via state file.
+
+The slow part of installing an app is `docker compose pull` on a large
+image (Jellyfin ~500 MB); without progress feedback, the UI modal sits
+dead on "Installing…" for 30+ seconds and the user wonders if it hung.
+
+This module mirrors the exact same shape as ``furtka.catalog`` and
+``furtka.updater`` so the UI can poll an install just like it polls a
+catalog sync or a self-update. The split is:
+
+- ``furtka.api._do_install`` runs synchronously: resolve source, copy
+  the app folder, write .env, validate path settings + placeholders.
+  Those are fast, and their failures deserve an immediate 4xx so the
+  install modal can surface them in-line.
+- After that the API writes an initial state file (stage
+  "pulling_image") and dispatches ``systemd-run --unit=furtka-install-
+  <name>`` to run ``furtka app install-bg <name>`` in the background.
+  That CLI subcommand is what calls ``run_install()`` here — it does the
+  docker-facing phases and writes state transitions as it goes.
+
+State file schema (``/var/lib/furtka/install-state.json``):
+
+    {
+      "stage": "pulling_image" | "creating_volumes"

+      "error": "details..."          // added at "error"
+    }
+
+Lock: ``/run/furtka/install.lock`` (tmpfs, reboot-safe). Global, not
+per-app — two parallel installs are not a v1 use-case and the lock
+keeps the state-file representation simple (one in-flight install at

+"""Stdlib-only password hashing, compatible with werkzeug's hash format.

+Why this exists: 26.11-alpha introduced auth via ``werkzeug.security``,
+but the target system doesn't have ``werkzeug`` installed (Core runs as
+system Python with only the stdlib — pyproject.toml's ``flask>=3.0``
+dep is never pip-installed on the box). Fresh installs from a 26.11 /
+26.12 ISO crashed on import; upgrades from pre-auth versions were
+double-broken by that plus a too-strict updater health check.
+
+Fix: replace werkzeug with stdlib equivalents using the same hash
+**format** so existing ``users.json`` files created by 26.11 / 26.12 on
+the rare boxes that happened to have werkzeug installed (Medion, .196
+after manual pacman) still verify.

+All four expose UMD globals (`THREE`, `gsap`, `ScrollTrigger`, `Lenis`).
+None are ES modules, so no `js.Build` step is needed — Hugo just fingerprints them.

+GSAP "Club" plugins (SplitText, MorphSVG, etc.) are **not** free for commercial use.
+Only `gsap` core + `ScrollTrigger` (both standard MIT-style license) are bundled.
