When hive-c0re can't read resource-limits.json and a limits drop-in already exists, it keeps the drop-in, but it wrote no memory cap file. A container whose runtime dir had no file yet (hive-c0re upgraded, /run not cleared) then started with no heap ceiling and no subagent MemoryHigh=, silently. `stage_limits` now writes the file on every call: from the new limits, or from the last `MemoryMax=` in the kept drop-in (`infinity` when it has none or can't be read). A missing or malformed cap file at boot is no longer silent. The generators run before the container's journal and an nspawn container has no /dev/kmsg, so a oneshot `hyperhive-memory-cap-check.service` logs a warning naming the path. The agent then runs with no JSC heap ceiling and no subagent MemoryHigh=; the container's MemoryMax= still applies. module-eval-agent-memory gains a case pinning how the ceiling reaches claude: `hive-agent` and `hive-subagent-daemon` neither set nor unset BUN_JSC_forceRAMSize, both generators and the check unit are installed. Part of #5081 (slice S0-2).

# `checks.script-test-agent-memory-cap` — runs the four readers of
|
|
# `/run/hive/memory-max-bytes` in ../agent-modules/memory-cap.nix: the
|
|
# environment generator, the unit generator, the boot check that warns about
|
|
# an unusable cap, and the login-shell snippet `/etc/set-environment` sources.
|
|
# The cases are in ./agent-memory-cap.sh.
|
|
#
|
|
# What runs is the rendered scripts. The one edit is the cap file's path, moved
|
|
# under the build directory, and the snippet's reference to the environment
|
|
# generator, pointed at that edited copy.
