The LocalService runner can't traverse the interactive user's profile the way
the old SYSTEM runner could — so a plugin can no longer read a file an app
running as *you* produced (the acute case: the Playnite exporter's library
JSON under %APPDATA%). Confirmed on-glass: as LocalService the glob finds
nothing and the profile is un-traversable.
Add the inverse of plugin-state: <config_dir>\ingest, granted BUILTIN\Users
Modify by plugins enable (disable reverts to inherited Users:RX). An
interactive-user app drops ingest\<plugin>\… and the de-privileged runner
reads it there — the one Users-writable carve-out in the otherwise
Users-read-only tree. SDK exports pluginIngestDir(name) to resolve it; on
Linux the systemd --user runner owns the config dir so same-user producers
write there with no grant.
Accepted tradeoff: the inbox is writable by any local user (trusted-single-
user model; it feeds only a LocalService runner). Consumers must treat ingest
data as lower trust than their own state.

The LocalService runner cannot write anywhere under %ProgramData%\punktfunk
(the config dir is Users-read-only), so a state-writing plugin's saveCache /
config-edit / first-run mkdir all fail EPERM — proven on-glass (rom-manager
only looked fine because its state dir was pre-created by an admin run and a
0-title reconcile skipped the write).
Add the one writable grant the model was missing, keeping the split crisp —
code dirs RX+WA, secrets R, and now a dedicated state root RW:
- plugins enable / build-scripting.ps1: create %ProgramData%\punktfunk plugin-state and grant LocalService (OI)(CI)(M); disable revokes. Users stay
read-only, so another non-admin still can't tamper with a plugin's launch
templates.
- SDK: export pluginStateDir(name) -> <config_dir>/plugin-state/<name>. Same
path on Linux (the systemd --user runner owns the config dir, writable with
no grant), so plugins use one branch-free helper.
Plugins must persist under pluginStateDir(), not straight under the config dir.
