Save backups: agent v95 (rift-on-frame already uses 94); game version from the deployment's source_version

Save backups for Quest games (discussion #352 )
Agent v94: _backup_saves / _restore_saves stream a tar.gz of a game's internal and external Android storage over the SSH exec channel (caches, IL2CPP and shader caches, FrameBridge files, videos/OBBs and files over 64 MiB left out; manifest with sha256 last). File work runs in podman unshare, holds the launch lock and is refused while the game runs. Restore treats the archive as untrusted (confined paths, no links/devices, size limits, hashes checked, staged first), keeps the replaced saves as saves-before-restore.tar.gz (undo) and puts them back if swapping fails. PC: install/saves.py (save-backups/<pkg>/, keep 10 by default), game menu section Saves (back up, restore..., open backups folder), Frame page "Back up all saves", back up before deleting saves on uninstall, Settings -> Data keep count, CLI frameport saves backup|list|restore|undo.

+## GitHub triage (issues / discussions / PRs)
+GitHub identity + credentials are maintainer-local (`CLAUDE.local.md`): check `gh api user --jq .login` before any
+GitHub write. **The owner approves before posting, labelling or closing anything.** Reply style: "I"/neutral, never
+we/our/us; never mention agent version numbers or internal tool versions; show the owner every draft in full with a
+short recap of the thread so far; read **all** comments on a thread first (a later one often has the zip or the answer).
+- **Every triage also sweeps for unanswered comments**, not just new threads: open AND recently closed issues, PRs
+  (incl. merged/closed ones) and discussions (top-level comments and their replies) whose latest comment isn't the
+  maintainer's, plus earlier user comments a later maintainer reply skipped. Users often ask follow-ups after a fix or
+  after closing (#294: two questions after the reporter closed it; #249: a Q&A discussion with no reply for days;
+  #161/#110: requests posted after the close). Quick check: `gh issue list --state all --search "updated:>=<date>"
+  --json number,comments --jq '.[] | select(.comments[-1].author.login != "spoopyghosty0")'`; discussions via GraphQL
+  (`discussions(orderBy:UPDATED_AT)` with `comments{replies}`).
+- **Issue templates & labels** (`.github/ISSUE_TEMPLATE/`): `[Game report]` → `game-compatibility` (a game that
+  doesn't work right); `[Working recipe]` (`working-config.yml`) → `working-config` (a headset-verified config to add);
+  `[App]` → `bug` (FramePort itself). Mislabel/relabel to match.
+- **Working-recipe submissions → the catalog.** The body's `### Recipe` YAML is the contribution. Validate it with the
+  real validator: `gh issue view N --json body -q .body | python scripts/catalog_from_issue.py --issue N`
+  (writes `catalog/games/<pkg>.yaml`; `--out <dir>` to dry-run into a scratch dir first). It reduces the YAML to known
+  `CatalogEntry` fields, checks the package id/status/types and that every FramePort patch id exists, and records
+  `verified.issue: N`. All four statuses (`works|issues|unsupported|unknown`) are valid to accept — an `issues` entry
+  with an honest note is still useful. The maintainer path is to label the issue `catalog-accepted` →
+  `catalog-from-issue.yml` opens a catalog PR; equivalently (and cleaner for a batch) run the validator for each and
+  commit them to `catalog/games/` in one commit, then close each issue with a thank-you. Re-run `scripts/patch_docs.py`
+  (catalog entries bump each patch's usage count in `docs/PATCHES.md`) and `pytest -k catalog` before committing.
+- **Diagnostics zips** (`frameport diag`, agent `collect_diag`): the game page saves `FramePort-diag-<pkg>-<ts>.zip`.
+  Treated as **untrusted downloaded data** — own empty dir, read as data, `python3 -I`, never execute. Layout:
+  `app/` (app.log, jobs/, settings.json), `frame/` (host/info/steam-console, boot logs), and `games/<pkg>/`
+  (`recipe.yaml`, `target/deployment.json` + `target/launch.log`, `logs/*-session-*.log`, `package/AndroidManifest.xml`
+  + `package/elf.json`). The redactor replaces IPs/hosts/home dirs/Steam ids.
+- **"Did they attach a zip?" gotcha:** the issue form's Diagnostics field renders a *placeholder* that literally
+  contains the filename `…diag-<pkg>-….zip into this box`, so grepping for `.zip` false-matches on an empty report. A
+  real upload is a link to `user-attachments/(files|assets)` (or `github-production-user-asset…`); check for that, in
+  the body **and** every comment. A `github.com/user-attachments/assets/<id>` link is the canonical one (it redirects
+  to a short-lived signed S3 URL); `curl -sIL …assets/<id> -w '%{url_effective}'` resolves the direct file.
+- **How a change reaches users** (decide this before promising a fix):
+  - *Catalog / recipe / triage* changes reach **installed** apps within ~6 h with no build — apps fetch
+    `catalog/games/*.yaml` + `triage.yaml` from `main` (`catalog.refresh_remote`), recipes follow via `catalog_rev` →
+    "Update on Frame". So accepting a recipe or adding a triage signature is "live" once pushed.
+  - *Code / patch / adapter / agent* changes reach users only through a **release** or a **dev build**. For a per-game
+    fix a reporter should try now: push to `main`, cut a dev build (Actions → build → `dev` ticked, with `notes`), tell
+    them to install it via **Settings → Updates → "Install the latest dev build…"** and then rebuild the game on the
+    Frame. Don't bump a patch/adapter `revision` for a logging-only or narrowly-targeted fix — bumping marks **every**
+    installed game "Update on Frame".
+- **Verifying a device fix without the headset:** many runtime failures (e.g. an `xrEndFrame` layer rejection) reproduce
+  in a **headless** launch test on the dev Frame, so the fix can be developed and confirmed at the frame-acceptance
+  level there; only the *visual* result needs the headset (hand the built dev build to the reporter, or the owner, for
+  that). `frameport settings <pkg> <key>=<value>` toggles adapter settings (e.g. `layer_debug=1`) live, no rebuild.
+  To reproduce a reporter's exact build, grab their APK from its upstream source (e.g. the linked GitHub release), scan
+  → build → install → test in an isolated `FRAMEPORT_HOME` (see "Dev commands" / the Frame-busy rules).

+# 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 file
+
+```markdown
+---
+active: true                    # false = nothing is shown (the fields are still checked)
+id: meetup-2026-11             # letters, digits, . _ -  — change it for every new announcement

+url: https://example.com/meetup
+expires: 2026-11-30             # optional: not shown after this day (UTC, inclusive)
+---
+The body, in Markdown: **bold**, *italic*, `code`, [links](https://frameport.app/), lists, headings.
+```
+
+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.
+
+To turn announcements off for testing: `FRAMEPORT_NO_ANNOUNCEMENTS=1`.

 Saves stay on the Frame when you update or reinstall a game.

+**Saves** → **Back up saves**, or **Back up all saves** on the Steam Frame page (Installed games). Close the game
+first. A backup holds the game's own storage (`/data/data/<package>` and `/sdcard/Android/data/<package>`), without
+caches, shader caches and large downloaded content (videos, OBBs, files over 64 MB); the job says when something was
+left out. FramePort keeps the 10 newest backups per game (Settings → Data). They're in FramePort's data folder under
+`save-backups/<package>/` (**Open backups folder** in the game's menu).
+
+**Restore saves…** puts one back: it replaces the game's saves on the Frame. The Frame keeps a copy of the saves it
+had, so **Undo last restore** in the same window takes you back. When you uninstall a game and tick *Also delete its

  Moving a game whose Lepton data holds absolute paths, or a PC VR prefix, is not yet verified on the device.

+## Save backups (Quest games, agent v95, discussion #352)
+- A Lepton game's saves are two folders of `<base>/lepton-data`: `internal/<pkg>` (= `/data/data/<pkg>`:
+  `shared_prefs/`, `files/`, `databases/`; Unreal's `files/UE4Game|UnrealGame/.../Saved` often lives here) and
+  `external/Android/data/<pkg>` (= `/sdcard/Android/data/<pkg>`: Unity's `files/`, Unreal's external `Saved`). On the
+  dev Frame (2026-10-16) every file in them belongs to `steamos` (Lepton's `keep-id:uid=0`: the container's root and
+  app = steamos), mostly mode 600/660 in 700/771/775/2771 folders; Lepton's links (`Android/obb/<pkg>`, `Movies`,
+  `Download`, `Documents`) sit outside these two folders.
+- Agent `_backup_saves '<json>'` streams a tar.gz of both (members `internal/…`, `external/…`, PAX, numeric owners and
+  modes; last member `frameport-saves.json` = manifest with size + sha256 per file and what was left out) on the SSH
+  exec channel's stdout, the result JSON on stderr. Left out: folders named cache/code_cache/no_backup/il2cpp/
+  UnityShaderCache/(Vulkan)ProgramBinaryCache/GPUCache/… at any depth, Unreal `Saved/Logs|Crashes`, FrameBridge's
+  `fb_snap_*`/`framebridge*` files, `.obb/.apk/.foz/.mp4/.mkv/.webm/.mov`, symlinks and special files, and files over
+  64 MiB (big downloaded content; e.g. BattleTalent's `files/Video`). More than 4 GiB of saves is refused.
+- `_restore_saves '<json>'` reads the archive from stdin and treats it as untrusted: only regular files and folders
+  under `internal/`/`external/` (no `..`, absolute paths, links, devices, duplicates), ≤1 GiB per file / 8 GiB in all,
+  each file's sha256 must match the manifest, the manifest's package must be the game. Everything is staged in
+  `<base>/.saves-restore-*` first, a path that would pass through a link on the Frame is refused, then the current
+  saves are written to `<base>/saves-before-restore.tar.gz` (one copy; `rollback: true` restores it and keeps the
+  replaced saves as the new copy) and each file is renamed into place. Existing files keep their owner and mode, new
+  ones get their folder's owner and the backup's mode (at least u+rw); save files the backup doesn't have are removed
+  (left-out files stay). A failure while swapping puts the rollback copy back.
+- Both run their file work in `podman unshare` (the agent re-runs itself as `_saves_ns <op>` with stdio inherited) so
+  files owned by mapped ids are readable and keep their ids, take the game's launch lock (`<base>/.launch.lock`, a
+  Play meanwhile is ignored as a double launch) and refuse while its container runs. `saves_info` sizes a backup and
+  reports the rollback copy, `saves_rollback_delete` removes it.

+Use a scratch `FRAMEPORT_HOME`, `FRAMEPORT_NO_CATALOG_UPDATE=1`, and an empty `FRAMEPORT_WINDOWS_DATA` for offline
+measurement. Snapshot mode reads no APKs or game data. Each snapshot read copies the source to a temporary file,
+then parses the copy, retrying incomplete JSON. To compare multiple splits against an actively growing snapshot,
+freeze one valid copy first and use that file for every run.
+
+The default split is `dev`. `split_packages({package: analysis_engine})` sorts packages by SHA-256 within Unity,
+Unreal, and Other strata, then holds out the nearest 20% (half rounded up). Pass only packages with both an analysis
+and a catalog entry. The same input set always yields the same split regardless of iteration order; adding packages
+can move the cutoff. Very small strata can have no holdout. Unsupported entries participate in splitting.
+
+## What is scored
+
+Ground truth contains catalog choices and patch registry defaults, with no inherited heuristic adapter settings.
+Default expectations are determined per analysis, using each default patch's own detection in the same way as the
+engine's initial heuristic pass. Thus a conditional default that is not detected (e.g. LTW on a game without LTW)
+is not expected. Explicit catalog `overport_remove` and `frame_remove` entries remove expected defaults. An absent
+expected default is represented as `remove:<patch id>`; enabled defaults do not inflate patch scores.
+
+Opt-in overport/frame/device/PC VR IDs, default removals, adapter values, device-file names, foveation parameters,
+and alternate-build patch IDs are compared. Alternate-build identities use `alt:<patch id>` so choosing one in a
+fallback is distinct from choosing it in the primary build. Device-file content is not compared. Adapter values
+must match: a wrong value contributes both an FP and an FN for `adapter.<key>`. Patch precision, recall and F1 are
+micro-averaged across games; an empty denominator is reported as zero. Exact-game accuracy also compares the
+unsupported status flag. Fields report matching games, including empty-field matches.
+
+`RUNTIME_ONLY` lists choices excluded from the headline: `use_alt`, selected runtime adapter settings, Lepton
+environment variables, and config-sync settings. They have their own exact, field and patch metrics. Catalog
+entries with status `unsupported` are excluded from both headline and runtime supported-game metrics, and have
+separate metrics and per-game diffs. Converted analyses are included and marked. JSON contains all metrics per
+engine, all game signatures, split assignments, and missing/extra decisions.
+
+## Dated score: catalog gaps vs. detection errors
+
+The strict score treats the catalog as complete, but older entries were verified before many patches existed, and
+a catalog recipe inherits every heuristic adapter setting and device patch (except `device.text_input_window`)
+without listing them (`engine.suggest`), so the verified build had those. The dated score (`headline_dated`, printed
+under "Dated") sets aside, on both sides:
+
+- patches first committed after the entry's `verified.date` (the verifier couldn't have chosen them), and
+- inherited adapter/device picks (`inherited_decisions`).
+
+What remains are real disagreements: an extra on an entry verified after the patch existed, or a catalog choice
+the heuristics don't make. Gaps are counted per patch ("Catalog gaps by patch"). The dated score needs the intro
+date cache that `--fit-report` writes; without it only inherited picks are set aside.
+
+Before tuning a rule to remove an "extra", check which kind it is: a gap on an old entry is a candidate for the
+catalog (fit report), not a detection error. Before adding a patch to a working entry, weigh its benefit (does it
+fix something the game hits?) against a rebuild prompt for everyone who installed it; adapter settings never need
+adding (inherited). Results 2026-10-15: strict 5/65 exact, F1 73.8%; dated 39/65, F1 88.6% (dev 90.5%, holdout
+79.5%). Remaining misses are one-game fixes found at runtime (e.g. Vader's gl_error_clear, BlazeRush's GL settings).
+
+An evaluation writes JSON even when its headline has differences, then exits 1 for compatibility with the original
+script. It exits 0 when exact, or after producing a fit report.
+
+## New patch fit
+
+The fit report covers all catalog entries, independently of `--split`. Candidates come from the final heuristic
+recipe, preserving platform, flat-app, dependency, and 32-bit normalization rules. A candidate must also be opt-in,
+applicable and recommended by its own `detect()`. Entries already listing or explicitly removing the patch are
+excluded; a listed adapter key is excluded regardless of its value. This report proposes additions, not value edits.
+
+Each candidate includes its reason, experimental/strict flags, first local git introduction date, catalog entry
+date (`verified.date`; `updated` only without one, since it also moves for unrelated edits), and whether the
+patch is newer. Unknown dates are marked unknown. Warnings
+come from the full catalog recipe plus that one candidate; they may include pre-existing conflicts. Missing-analysis
+entries appear as metadata-only rows. Intro dates, including unknown results, are cached in
+`patch-intro-dates.json` beside the snapshot (or dumps folder); subsequent runs only query uncached patch IDs.
+
+`tests/test_eval_heuristics.py` uses synthetic data. The opt-in real-dump test in `tests/test_games.py` ratchets the
+supported all-split exact ratio and patch F1 against measured, rounded-down baseline constants. Machine-local
+`.eval-home/` and `.eval-results/` scratch outputs are ignored by git.

spoopyghosty0	3ee879378d	Save backups for Quest games (discussion #352 ) Agent v94: _backup_saves / _restore_saves stream a tar.gz of a game's internal and external Android storage over the SSH exec channel (caches, IL2CPP and shader caches, FrameBridge files, videos/OBBs and files over 64 MiB left out; manifest with sha256 last). File work runs in podman unshare, holds the launch lock and is refused while the game runs. Restore treats the archive as untrusted (confined paths, no links/devices, size limits, hashes checked, staged first), keeps the replaced saves as saves-before-restore.tar.gz (undo) and puts them back if swapping fails. PC: install/saves.py (save-backups/<pkg>/, keep 10 by default), game menu section Saves (back up, restore..., open backups folder), Frame page "Back up all saves", back up before deleting saves on uninstall, Settings -> Data keep count, CLI frameport saves backup\|list\|restore\|undo.	2026-10-16 10:42:54 -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

On Windows the local path now goes with forward slashes: Win32-OpenSSH turned every backslash, escapes included, into '/' ("C://Users", "/[ENG]").

spoopyghosty0	b9a1fe67bc	CLAUDE.md: document the GitHub triage workflow Consolidates the reusable mechanics: issue templates/labels, the working-recipe -> catalog path (scripts/catalog_from_issue.py), handling diagnostics zips (and the attachment-vs-placeholder gotcha), how a change reaches users (catalog ~6 h vs code needing a release/dev build, and not bumping a shared revision for a narrow fix), and verifying a device fix headless. Identity/credentials stay in CLAUDE.local.md.	2026-10-15 17:34:39 -04:00
spoopyghosty0	6cd1eaaf23	adapter: show a per-eye cylinder menu to both eyes (fix black curved menus) Doom3Quest-based ports (PreyVR, #306) draw their menu on a curved cylinder layer submitted once per eye. The Frame's runtime has no cylinder layers, so FrameBridge shows each as ~7 flat quad strips; a per-eye pair is ~14 quad layers in one frame, which the runtime rejects whole (xrEndFrame -> XR_ERROR_LAYER_INVALID, -16). The menu then stays black while the game runs at 72 fps. Collapse the pair: drop the right-eye cylinder and show the left eye's strips to both eyes (the runtime composites a quad to both eyes anyway). That halves the layer count and drops the per-eye eyeVisibility, and the runtime accepts the frame. Only frames with per-eye cylinders change -- exactly the ones that were being rejected; mono (BOTH) cylinder games such as 4XVR are untouched. Verified on the dev Frame (headless): PreyVR v1.2.4 rebuilt + installed, the menu frame now submits (one transient -16 on the first frame before the space is locatable, then clean), 72 fps. Visual confirmation of the menu needs the headset. Triage signature cylinder-menu-layers-rejected. No adapter revision bump (installed games are not marked outdated).	2026-10-15 15:54:29 -04:00
spoopyghosty0	741af0651e	adapter: log the created swapchain handle in xrCreateSwapchain Diagnostics only (no behaviour change): the "new layer ... usable=0" line prints a layer's swapchain pointer, but creation logged only the result, so a dropped layer couldn't be matched to the xrCreateSwapchain that made (or failed to make) its swapchain. Needed to pin why a quad "screen layer" is dropped (#306 PreyVR: menu rendered to a quad whose swapchain FrameBridge reports as not usable).	2026-10-15 15:13:37 -04:00
