n0mad1k 22b1415b43 Guard probe_target against creating phantom mountpoint dir

probe_target() unconditionally ran mkdir(parents=True) on TARGET_DIR. When
TARGET_DIR sits under an unmounted FUSE drive, this materialized the mount
root (e.g. ~/pCloudDrive) as a plain local directory, occupying the
mountpoint and blocking the pCloud client from ever mounting.

Add optional mount_root config key (env COE_MIRROR_MOUNT_ROOT). When set,
probe_target requires the path to be a live mountpoint and TARGET_DIR to be
under it before any mkdir; otherwise it returns False and the run queues to
pending. Unset preserves prior behavior for local targets.

coe-mirror notes

Created: 2026-06-11. Purpose: autonomous mirroring of Nightmare_Eclipse repos from Church of Malware to local pCloud storage.
Source API: Forgejo public REST at git.churchofmalware.org, no auth needed.
Owner being mirrored: Nightmare_Eclipse (8 active repos as of creation).
Destination: ~/pCloudDrive/Hacking/Nightmare_Eclipse/.
Schedule: 00:00 + 12:00 daily, catch-up on boot via Persistent timer + OnBootSec.
Design rationale:
- FUSE-safe placement uses shutil.copy2 + size verify + unlink, not os.rename, to handle pCloud FUSE semantics.
- pCloud daemon auto-start was rejected — no user unit exists; DISPLAY=:0 spawning is unreliable. Tool relies on Persistent timer + pending-flush for recovery.
- commit.sha is NOT in the repo-list API response — two-call approach (list, then per-repo branch) is retained.
DevTrack: Not created at creation time (oraculo offline, Tailscale last seen 2d ago, carbon roaming off home LAN). Add a coe-mirror project + item retroactively when oraculo returns.
Matrix notification: Stub-only at creation time, Matrix server down. Real implementation deferred until home Matrix server is back.

2026-06-14 — Matrix notification swap

Replaced notify() stub with real Synapse send. Targets General room (!MBpPtYlQYMcngtpvJt:m.mealeyfamily.com).
Auth: password login via MATRIX_USER + MATRIX_PASSWORD from Infisical matrix/ at refresh time. Token cache at ~/.local/share/coe-mirror/matrix-token.json (chmod 0600), refreshed when <30 min left or on 401.
Non-fatal failures — Matrix outage does not break the mirror.
Env overrides: COE_MIRROR_MATRIX_ROOM, COE_MIRROR_MATRIX_HOMESERVER.
Pre-deploy step: invite @intel-bot:m.mealeyfamily.com to General once Synapse is back. Without joined membership, sends will 403.
DevTrack: #1172.

2026-07-10 — mount_root guard (phantom pCloudDrive fix)

Bug: probe_target() did TARGET_DIR.mkdir(parents=True, exist_ok=True) unconditionally. When pCloud FUSE was unmounted, this created ~/pCloudDrive/... as plain LOCAL dirs, occupying the mountpoint and blocking the pCloud client from mounting. Live state on carbon confirmed: ~/pCloudDrive was a plain dir, not a mountpoint, with 22 stray zips inside.
Fix: new optional config key mount_root (env COE_MIRROR_MOUNT_ROOT). When set, probe_target() requires os.path.ismount(mount_root) AND that TARGET_DIR is under mount_root before any mkdir; otherwise returns False (queues to pending). Never creates the mount root. Empty/unset = old behavior (local targets like ~/coe-mirror).
Local config sets mount_root = "~/pCloudDrive".
Recovery run: stopped/masked timer, staged the 22 zips aside, removed the local ~/pCloudDrive, relaunched pCloud, verified mountpoint, moved zips onto the live mount, unmasked timer.
DevTrack: #1307.
