Foundation for stepped upgrades. Answers one question only — WHICH
versions, in WHICH order — with no side effects, so it can be tested
exhaustively. Applying the rungs is a separate job.
Nextcloud refuses to skip a major ("Updates between multiple major
versions and downgrades are unsupported") and will not start; databases
behave the same way about their data directory. For those apps 31 -> 34
is three upgrades, each with a migration that must finish before the
next begins.
Built by PROBING each candidate rung, not by enumerating tags — because
enumeration is provably unsafe here. Docker Hub pages at 100 ordered by
recency, and the first real-registry run proved the danger: it produced
v4.2 -> v4.4 -> v4.5 -> v4.6 for mastodon, silently skipping v4.3, which
exists (HTTP 200) but had fallen off the newest-100 listing. Skipping a
rung is the precise failure this file exists to prevent, so the ladder is
now built by incrementing and probing: v4.2 -> v4.3 -> v4.4 -> v4.5 ->
v4.6, 4 steps.
Guarantees: same shape only (never 31-fpm-alpine onto 31-apache),
strictly ascending, never a downgrade, rolling tags refused outright, and
a version upstream never published is stepped over only because the probe
said so. If a continuous path to the target cannot be constructed it
returns 1 and prints nothing — refusing to guess, because a wrong ladder
means a skipped migration.
20 unit tests, including the exact listing-truncation case above and the
numeric ordering that would otherwise drive an app backwards (0.9 vs
0.10). Real registry: nextcloud 3 steps, mastodon 4, stalwart current.
