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).

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).
