thethreemagi ce2b49ef73 plex: pin image to 1.43.3.10828-ls316 (the exact running version)
Same PMS build the database was born on. SQLite schema upgrades are
one-way; a surprise :latest bump no longer gets a vote. Bump the pin
deliberately when choosing to upgrade.

# PINNED 2026-08-02 to the exact version running (and matching the migrated
# database — Windows also ran 1.43.3.10828, so no schema upgrade occurred).
# SQLite schema upgrades are ONE-WAY; upgrade by bumping this pin
# deliberately, never by riding :latest.

# NOT OPTIONAL. Plex's local discovery (GDM) and client auto-detection rely
# on broadcast traffic that a bridge network silently eats. (DLNA is off on
# this server, so discovery — not DLNA — is the reason.) This is also why
# Plex does not sit behind NPM like everything else here: proxy host 17
# already points plex.thewichersfamily.com at 10.0.1.20:32400 and needs no
# change, because the IP does not move.

# No PLEX_CLAIM. The migration carries MachineIdentifier,
# ProcessedMachineIdentifier and the online token across in
# Preferences.xml, so this server IS the existing server — already
# claimed, shared users intact, clients not needing to re-add it.
# Claiming would create a NEW server identity and throw that away.
devices:
# Quick Sync on the UHD 630 — DECIDED 2026-07-31. No session cap and
# better HDR tone mapping than the Pascal-era NVENC on the 1070, and the
# i915 driver lives in the kernel, so nothing breaks on updates. The
# GTX 1070 stays free for other work. Requires the BIOS iGPU
# Multi-Monitor toggle or /dev/dri does not exist.

# ---- Plex data directory (SSD): database + Metadata, NOT Media/ -------
# The SQLite database is the most latency-sensitive thing on the box and
# belongs on flash. Metadata/ (25 GB of posters) rides along. The 337 GB
# Media/ preview cache does NOT — see the bind below.
- type: bind
source: /srv/plex/config
target: /config
# ---- Preview/thumbnail cache on the 3 TB ext4 disk — NOT the SSD ------
# Mike's call 2026-07-31: 337 GB is too large for the 500 GB SSD, so
# Media/ lives on /srv/data (the former D:, now ext4) from day one.
# Long-form syntax deliberately: the target path contains spaces, which
# the short "a:b" form handles badly. Docker orders mounts by target
# depth, so this correctly lands inside the /config mount above.
#
# Plex does NOT support relocating this directory natively — this bind
# mount is the mechanism. After first start, force thumbnail generation
# on one title to prove writes succeed across the filesystem boundary
# (EXDEV) — that failure mode can only be tested, not reasoned about.

# ---- NAS media, mounted at the SAME paths the database stores ---------
# The remap rewrites \\korval\X -> /mnt/nas/X, so the container must see
# exactly /mnt/nas/X. Six separate entries rather than one bind of
# /mnt/nas, because a plain bind does not carry the submounts beneath it.
# Read-only here AND at the mount AND at the Synology — the mediabox NAS
# account has no write permission on the library shares. media_pc (the
# box's write share) is deliberately not exposed to Plex.
