User insight: hardlink breakage only happens at deploy time (scp file
replacement / git checkout-merge), so detection must be welded INTO the
deploy pipeline, not left to daily audit.
Three automatic layers, no reliance on discipline:
1. systemd path watcher (profile-scripts-sync.path): watches
deploy/profile-scripts/ directory, auto-fires sync_profile_scripts.sh
on any change. Verified: fires within 4s of file replacement, logs to
gateway/logs/link_sync.log (runs as hmo user)
2. git hooks (.git/hooks/post-merge + post-checkout on 246 repo):
auto re-link after git operations
3. Manual fallback: sync_profile_scripts.sh (now self-logging)
dev-spec red line #6 updated: SSOT rule now documents the three layers
and states breakage only happens at deploy time.
Real errors fixed (all verified by manual run):
- price_monitor.py: shares None -> TypeError at L584 (now completes 3m7s,
full 39-stock reassess + zone triggers + Dad push)
- market_insight.py: net_inflow None -> TypeError at L142 (now 0.3s, 5 insights)
- promote_candidates.py: add busy_timeout=30s (DB lock under concurrent writes)
- premarket_full_review.py: 12-dim analysis now detached background launch
(was doomed by cron 120s script timeout no matter what)
Systemic:
- HERMES_CRON_SCRIPT_TIMEOUT=600 drop-in for both gateway services
(fixes mofin_health SIGTERM, market_watch timeout, memory_guardian timeout)
- sync_profile_scripts.sh: re-hardlink deploy->profile scripts after every
deploy (scp replaces files = new inode = broken hardlink = cron silently
runs stale code; this caused promote to keep failing after my first fix)
Monitoring false-alarm fixes (the '花瓶' problem):
- mofin_health.py: legacy JSONs that migrated to DB (multi_tf_cache/
macro_context/market/live_prices/price_history/macro_risk_state) no longer
warn 'no readers'; marked as migrated
- NEW db_freshness section: real pipeline health from DB tables
(mtf_cache 0.4h / macro_context_log 2h / market_snapshots 2h /
live_prices 0.4h / price_events.json 0.4h — ALL HEALTHY)
- price_events freshness reads live JSON store (DB table is legacy)
- market.json placeholder created (13+ scripts have fallback paths)
Investigation notes: wiki-self-growth 03:04 key1 429 predates full key6
activation on default gateway; current 8642 verified on key6 and working.
Weekend 'Blocked' jobs verified fixed (vacuum_state_db passes).
