The ONLY image move in this commit. Written by upgrade-test.py --write-ladder:
- bench LXC 9401 (harness v4, the bench's own BookStack fixture): FROM settled, the seeded admin
read back, migrations ran, read back after, 10-minute memory watch peak 43.7 % (anon), 0 kills,
0 restarts; the abort (old image back) starts and serves the data;
- box 9202 (controller 0.283.1, the product's guarded Update, drill catalog): done in 64.6 s, the
seeded admin read back through the app's own CLI.
The superseded step keeps its definition at steps/fdb7afbec5ea4dbc.{yml,felhom.yml} (09 §6.4 part 5).
The database half only, as before (R-460). MariaDB 12.3 does not move.

The ONLY image move in this commit. Written by upgrade-test.py --write-ladder from both venues:
- bench LXC 9401 (harness v4): converted 15 -> 18 in 13.3 s, check equal over 94 tables, the seeded
check-in weight read back, 10-minute memory watch peak 31.3 % (anon), 0 kills, 0 restarts;
- box 9202 (controller 0.283.1, the product's guarded Update, drill catalog): CONVERTED 15 -> 18 in
9.8 s (2 databases, 94 tables, 261 rows equal), done in 58.5 s, PG_VERSION 18, the weight read
back through the front door. Undo case on 9202 (after a reinstall at 15): the load failing
(adminpack) -> undone in 74.9 s, back on 15, the weight read back.
Target 18: SparkyFitness's own upstream compose pairs v0.17.3 with postgres:18.3-alpine at
/var/lib/postgresql (09 decision 42's rule). PGDATA is left as it was (/var/lib/postgresql/data/pgdata),
now a folder inside the moved volume — the definition both venues tested. Only the header comment
changes beside the image and its mount.

Written by upgrade-test.py --write-ladder: bench (harness v4) healthy in 217 s, the world-data file present and reused ("Latest data already imported"), 6 migration lines, seed read back, memory watch anon peak 73.0 %, 0 restarts; box 9202 through the guarded Update in 204 s with the product's default 5-min wait (a first try under the drill's 90 s wait was UNDONE correctly). Same commit: (1) the frontend healthcheck override is dropped — v0.13.0 brings its own (node at /usr/bin/node); (2) a world-data file that does not parse to its end is renamed aside before start so download-countries fetches it again — with an import pending, the image's own start crash-looped 10 times on IncompleteJSONError, with the step it was set aside, downloaded and healthy.

"Upgrading nextcloud from 34.0.1.2 ..." then the seeded user read back
through occ (a never-created uid reads absent on the same call). The
bench's drive tree changed under the app (its appdata), so the entry is
marked files_may_change: an automatic update needs a fresh copy of the
files (09 decision 13). Memory: nextcloud's own 7.9 % (cgroup 100 % =
file cache), db 24.2 %; 0 kills. Abort refuses ("the version of the data

update_ladder: in .felhom.yml, one JSON entry per line (spiked live on
controller v0.266.0 and v0.267.0 first). Two gates: check-test-record.py
(static, CI too) and check-test-record-move.py (history + registry for
moved refs only). 16 decoys, 3 red-proofs. The ONLY writer is
upgrade-test.py --write-ladder (bench AND box proven, digests resolved).
Harness v3: box fixtures on the bench, files_may_change.

No image: line moved.
paperless-ngx has no container named after its stack, so its probe had NEVER run on any box.
immich has four immich-* containers and no exact match, so the old first-prefix rule picked
whichever came first - possibly the database.
The gate now resolves the target by the same four rules as findProbeContainerMeta: exact name,
explicit container, a UNIQUE prefix, else refuse - and refusing is right, because verifying waits
on this probe and a successful update of such an app gets stopped.

WEB_SERVER_CONCURRENCY=2, limit left at 768M. No image: line moved.
768M was still a guess and it was wrong: kills slowed from ~12/min to ~7/min and stopped nothing.
Measured instead - each warm uvicorn worker holds ~216 MiB, so four plus the master reach ~882 MiB,
and the cgroup's memory.peak read exactly 768 MiB.
/init:143 runs --workers "${WEB_SERVER_CONCURRENCY:-4}". Four is a server default; this is one
household on one small box. Two measure ~450 MiB, fit 768M with headroom, and halve the CPU churn.

No image: line moved, so no catalog_since moved.
Measured on demo-hp after this morning's promotion: OOMKilled true, 4530 gunicorn worker SIGKILLs
in six hours, ~500% CPU in a permanent restart storm, host load 5.2 while otherwise idle. It ran
clean for two hours first, which is why the walk on the scratch guest did not catch it.
The update reported `done` and the app read `running` the whole time - nginx answers 200 while the
workers behind it die. Nothing alarmed; the operator heard the fans.
768M is a measured first step, not a final answer.

The ONE engine move in this series, and it is deliberate. Walked through the product's own
guarded Update on scratch guest 9202 during the update night: 217.4 s end to end, seed read back
through nextcloud's own front door before AND after, healthy after.
Permitted since R-469 (Slice 4 shipped): MARIADB_AUTO_UPGRADE=1 is already in this template and
converts the datadir. check-engine-major.py was run against this exact commit and ALLOWS it by
name, rather than being assumed to.
