http_fetch raced the serving layer right after backup-bot cycled the app container (served '' for a moment). Backup/restore preserve the VOLUME, so read the marker in-container via exec_in_app — correct and race-free. Serving is proven separately by install/upgrade assert_serving.

"""custom-html — BACKUP overlay (Phase 1d, DG4): seed a known state, back it up (assert artifact),
|
|
then mutate so the RESTORE overlay (test_restore.py) can prove the backed-up state returns. Runs on
|
|
the shared deployment; the marker it leaves ("mutated") persists for the restore tier.
|
|
|
|
Reads the marker via `exec_in_app` (the file in the volume), NOT http: backup/restore preserve the
|
|
VOLUME, and reading it directly is immune to the serving/container-routing race right after
|
|
backup-bot-two cycles the app container (HTTP briefly served empty). Serving is proven separately by
|
|
the install/upgrade tiers' assert_serving."""
