Statusline on Linux: memory line stuck on "JUST NOW" because last-review age is parsed with BSD-only date -j #2260

What happens

On Linux the statusline's 🧠 memory line never shows the real age of the last memory review. After any review that wrote something, it stays stuck on SAVED N NEW MEMORIES JUST NOW until a health warning replaces it.

Cause

LifeOS/install/LIFEOS/LIFEOS_StatusLine.sh:1879 parses last_review_at with BSD-only flags:

_then_epoch=$(date -u -j -f "%Y-%m-%dT%H:%M:%S" "${_mem_last_review%.*}" +%s 2>/dev/null || echo "$NOW_EPOCH")

GNU date rejects -j (date: invalid option -- 'j'), the fallback returns $NOW_EPOCH, the age becomes 0, and the -le 30 branch at :1929 keeps printing "JUST NOW".

The script already has a portable parser, parse_iso_epoch() at :224, which switches on DATE_FLAVOR; this line just doesn't use it.

Fix (one line)

_then_epoch=$(parse_iso_epoch "$_mem_last_review"); [ "$_then_epoch" -gt 0 ] 2>/dev/null || _then_epoch="$NOW_EPOCH"

The guard keeps the original fallback, since parse_iso_epoch returns 0 on failure.

Verified

Linux (Arch/Hyprland), GNU coreutils date, LifeOS 7.40.4. The script was run with the same stdin before and after the change:

• before: 🧠 SAVED 3 NEW MEMORIES JUST NOW · 19% FULL
• after: 🧠 OK · REVIEWED 10M AGO · NEXT IN 3 TURNS · 19% FULL (the review had been ~10 min earlier)

main still has the BSD-only line.
