That step still pinned immich-postgres at 512M. It re-runs the geodata import (v3.0.3 ships geodata
dated 2026-07-13, v3.2.2 2026-08-30 — read inside both images), the load R-732 measured at ~575 MB.
Re-proof on bench 9401, swap 0, on the step's OWN definition with only the limit changed (768M;
mem_limit 4096M -> 4480M): `Starting geodata import` ... `Geodata import completed` in 17 s, the
database's kill counter 0 from its birth, the album read back, 10-min watch 0 kills (anon peak 29.6 %).
Written by upgrade-test.py --restep; the ladder entry is untouched. No box reporting to the hub runs
immich (hub /apps, same day).

- upgrade-test.py --restep <verdict> --definition <dir> --catalog <c> --evidence <rel>: the only way a
superseded step's own files (steps/<key>.yml + .felhom.yml) change after the fact (Part D: immich's
step 0b8272068aab36bf still pins 512M). Refuses a non-proven or OOM-killing re-proof, the head entry,
and a definition whose images are not the step's; leaves the ladder entry untouched (digests, box
evidence, the box's failed-step fingerprint). Two tests; the gate accepts the result.
- zipline's verify waited on `/` for 200/302/307; on 9202 it answers 301 and the readback returned
False with no line — it now waits on /api/healthcheck like its seed.

The ONLY image move in this commit; the limit rides it (09 decision 39's precedent), because the step
itself re-runs immich's geodata import (228 294 -> 228 571 places) — the load that killed the database.
Cause, measured on the bench (audits/immich-first-start-2026-09-30/A-cause.md): the first-start import
runs up to 9 concurrent 5000-row INSERTs; the database then needs ~400 MB anon + ~170 MB touched
shared_buffers (the image's own postgresql.conf fixes 512MB). At 512M with no swap: 61 kills; with 512 MB
swap: 0 (swapped ~70 MB) — why 9202 passed; shared_buffers 128MB alone: still killed; 1024M: 0; 768M: 0.
Proof at the new definition, fresh install from birth, no swap: bench x2 (anon 409/412 MB = 53 %, 0 kills,
import 8.1 s) and box 9202 (anon 368 MB = 48 %, 0 kills, swap.peak 0).
Step, written by upgrade-test.py --write-ladder: bench (harness v4) proven, 10-min watch 0 kills 0
restarts, anon peak 51.1 %; box 9202 through the guarded Update: done 58.5 s, album read back, the running
database limit 805306368 after. The step carries `files_may_change` (the harness saw only immich's six
13-byte `.immich` folder markers rewritten at start) — the night leg takes it only with a whole copy.
Per-box cost: +256 MB on immich-postgres; `mem_limit` 4096M -> 4480M (the old figure was already 128 MB
under the sum of the four limits). Header comment corrected (it said postgres 256M).

Proven on 9202 with controller 0.279.0 (drill 5ac5daf): the default no longer logs in, the generated first
password from the app page does, a wrong one does not. Copy freeze: bookstack's new/changed strings signed off.

Proven on 9202 with controller 0.279.0 (drill catalog c4cfb83): the default no longer authenticates, the
generated first password from the app page does, a wrong one does not; a restore keeps it.

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.
