Announcements: a one-time pop-up in the app
Source of truth: announcements/current.md on main (front matter: id, title, date, optional image/button/expires; Markdown body), read from raw GitHub every 6 h like the catalog, so a push reaches users without a release. Ships switched off (active: false). Shown only to people who used FramePort before the announcement's date, never on a first start; any close (X, click outside, Escape) dismisses that id for good, and a new announcement = a new id. Centred over the content area, right of the sidebar. announcements/README.md explains the file; ui_smoke.py --announcement renders it.

+# Announcements
+
+`current.md` is the one announcement FramePort shows as a pop-up in the app. Edit it on `main`: the app reads it
+from GitHub `main` (raw.githubusercontent.com) at most every 6 hours, so a push reaches everyone without a release.
+
+## Who sees it
+
+- **Only people who already used FramePort before the announcement's `date`.** A new install never shows one, and
+  nor does an announcement published before FramePort was installed.
+- **Once.** Closing it in any way (the X, a click outside it, Escape, or its button) dismisses it for good. The app
+  remembers dismissals in its settings (`announce.dismissed`).
+- **A new announcement = a new `id`.** Fixing a typo with the same `id` doesn't show it again to anyone who closed it.
+  A new `id` shows to everyone who used FramePort before its `date`, whether they closed the earlier one or not.

+```
+
+The body is Markdown (no HTML). A `date` in the future works as a schedule: nobody sees it before then.
+
+Images look best at about 2:1 (e.g. 1200×600). The pop-up is 600 px wide and shows between 140 and 320 px of the
+picture's height.
+
+`pytest tests/test_announcements.py` checks this file, so a broken announcement fails CI instead of silently showing
+nothing.

spoopyghosty0	960da4469b	Announcements: a one-time pop-up in the app Source of truth: announcements/current.md on main (front matter: id, title, date, optional image/button/expires; Markdown body), read from raw GitHub every 6 h like the catalog, so a push reaches users without a release. Ships switched off (active: false). Shown only to people who used FramePort before the announcement's date, never on a first start; any close (X, click outside, Escape) dismisses that id for good, and a new announcement = a new id. Centred over the content area, right of the sidebar. announcements/README.md explains the file; ui_smoke.py --announcement renders it.	2026-10-16 09:23:46 -04:00

spoopyghosty0	39e1762e53	Game menu: Update with a newer version… for Linux apps and PC VR games (#161 ) Follow-up to "Update with a newer APK…": Linux apps take their new AppImage/archive or folder (a file or a folder picker, like the app was added), PC VR games their new game folder. pipeline.replace_linux_app / replace_rift_game re-run the add path (add_linux_app(replace=) / add_rift_game(replace=)): the entry keeps its package (so the Steam shortcut), name, artwork, tags, switches and the user's recipe; a folder keeps the program chosen before if it's still there, else FramePort picks again (and asks, for ambiguous PC VR games). A name that looks like another app's is allowed with a heads-up. The entry gets a new source_id, recorded in the deployment's recipe at install (no agent change): components.source_replaced shows the Frame copy (and a PC install, pc_outdated) as outdated until then. Such an install also re-sends same-size files changed after the last install (installer.changed_since), since uploads otherwise skip files the Frame has with the same size. The old PC VR folder is left out of later scans (replaced_dirs). CLI: frameport new-version <game> <path> (APKs too). Docs: INSTALL.md.	2026-10-15 20:10:50 -04:00
spoopyghosty0	3d260dccb1	OpenSSH uploads log in like the Frame connection; SSH key files in Settings (#242 ) A Frame that only authorizes the user's own key refused OpenSSH, which offered FramePort's keys alone (IdentitiesOnly), so every upload fell back to Paramiko. The connection now records which login worked (Frame.auth): after a login with this PC's own keys/agent OpenSSH also offers private copies of ~/.ssh/id_* (OpenSSH skips its defaults once -i is given) and the agent; a refused strict login is retried that way once. FramePort doesn't add its key to the Frame for this. New: Settings > Installing > SSH keys (library ssh.extra_keys, CLI frameport frame ssh-keys): extra private key files for the connection and OpenSSH, checked with Paramiko (passphrase keys: use the agent). OpenSSH runs with -v and a refused login's error lists the keys offered and its warnings. whoami's SID is read from bytes (non-ASCII user names). Checked with Windows ssh.exe/sftp.exe against the Frame.	2026-10-15 19:58:58 -04:00
spoopyghosty0	26a34ddadb	OpenSSH uploads: don't escape glob characters inside sftp's quotes (#324 ) sftp escapes * ? [ inside double quotes itself, so FramePort's extra backslash became part of the path: a folder named "... [ENG] ..." failed every OpenSSH upload (on Linux too) and fell back to Paramiko. On Windows the local path now goes with forward slashes: Win32-OpenSSH turned every backslash, escapes included, into '/' ("C://Users", "/[ENG]"). Checked with Windows sftp.exe and Linux sftp against the Frame (put and reput, sha256 match).	2026-10-15 19:58:57 -04:00

The oculus-entitlement signature is PC VR only, so the Quest log had no finding. New Quest signature meta-entitlement (error: offline games may log it and play on; an online game's exit fails the test). FramePort doesn't get around entitlement checks. docs/GAMES.md regenerated (it was also behind on other catalog entries).	2026-10-15 19:34:51 -04:00
