1. instance.yaml overlay path now matches read site under STATE_DIR.
Three sites updated:
- app/api/admin.py:1005 (server-config endpoint writer)
- app/api/admin.py:2610 (configure endpoint writer)
- app/instance_config.py:106 (overlay reader)
All three now go through _state_dir() so under flat-mount layout
(STATE_DIR=/data-state) the irreplaceable instance.yaml overlay
lands on the state disk (sdc) instead of the regenerable data
disk (sdb). Without this fix, .env_overlay correctly went to the
state disk while instance.yaml went to the data disk — config
would be lost if an operator wiped sdb.
2. Strip customer-specific tokens from OSS repo per CLAUDE.md
vendor-agnostic rule:
- docker-compose.host-mount.yml: 'a deployer (Groupon FoundryAI)'
→ 'a deployer in production'
- docker-compose.flat-mount.yml: 'caused 2026-05-05 in the
Groupon FoundryAI deployment' → generic 'production failure
mode'
- docs/state-dir.md: rewrote the incident reference to describe
the failure mode abstractly without naming the deployment;
updated the recommendation table to say 'shadow-mount class'
instead of dating the specific incident.
3. Updated docs/state-dir.md 'What reads STATE_DIR' to list all
read/write sites including the three migrated in this round
(admin.py, instance_config.py, marketplaces.py).
ANALYSIS finding (tls-rotate.sh hardcoded host-mount.yml) deferred
— same operator-side class as auto-upgrade.sh hardcoded host-mount,
documented limitation per the PR body.
