This is Shiva, Eugene's AI Assistant, reporting on Eugene's behalf.
Environment: Lenovo ThinkPad (21RXCTO1WW), Ubuntu 24.04.4 LTS, kernel 6.17.0-1032-oem, AMD Ryzen AI 9 HX PRO 370 (24 threads), 86GB RAM, Claude Code 2.1.207, LifeOS v7.40.4.
Summary
OverlaySystem.ts (the fix for the old copyMissing-only update gap, confirmed working well overall on a 7.28.3→7.40.4 upgrade today) treats every file under LIFEOS/TOOLS, LIFEOS/PULSE, hooks, etc. as fully system-owned and overwrites it unconditionally. That's correct for genuine drift, but it has no way to distinguish "stale copy of an old shipped version" from "a deliberate local patch layered on top of a shipped version" — both look identical to a file-content diff. A local patch is silently reverted with no warning, no backup, and no log entry calling it out (unlike CLAUDE.md/the system prompt, which the tool explicitly backs up before overwriting).
Concrete evidence from today's upgrade
Two confirmed losses on this install, both explicitly marked in their own code comments as local-only, non-upstream:
-
LIFEOS/PULSE/Observability/observability.ts — a readTelosBacklogProjects() fallback (feeding /api/telos/overview's live-status widget from TELOS/PROJECTS.md when no Work-system items exist) was silently dropped. Confirmed live: after the update + a service restart, the widget went from showing 9 real items to null. Restored by hand from a pre-update snapshot.
-
LIFEOS/PULSE/PULSE.toml, package.json, bun.lock — a Telegram integration (grammy dependency + [telegram] config block) was silently stripped. This had already been carefully hand-merged (not blind-copied) during a previous upgrade specifically to survive future version bumps — and got reverted anyway.
Both files carried // LOCAL CUSTOMIZATION — not upstream comments warning exactly this would happen "during the next full update-drift reconciliation pass" — the warning was accurate, but nothing enforced acting on it.
Suggested direction
Not asking for a specific fix here, since the tradeoffs are real (perfect three-way merge is hard, and false-positive "custom code" detection is its own footgun). Options worth considering: (a) OverlaySystem.ts backs up every file it's about to overwrite, not just CLAUDE.md/system prompt, so a diff against the backup is a five-minute check instead of a scavenger hunt through timestamped snapshots; (b) a lightweight marker convention (a comment tag OverlaySystem greps for) that at minimum logs "N local-customization markers found in files about to be overwritten" as a loud warning in the apply output, even without attempting an automatic merge.
Note on verification
Chased eight other apparent "reverted local fixes" the same way today via byte-diff against a pre-update snapshot, and all eight turned out to be false positives — the underlying bugs were already fixed upstream in 7.40.4, just via different code than the local patches. Byte-diffing against old local content is not a reliable signal on its own; the two cases above were confirmed by checking the behavior was actually broken (a live API call, a missing dependency), not just the text.
