An opencloud snapshot carried 174 entries, and every line repeated the whole
path - the deepest ran about 150 characters, most of it the same prefix as the
line above. Print the basename at its depth instead, with a glyph per kind:
folder, json, journal or log, plain text.
The separator is swapped for \001 across the sort. Without it a directory and
its children come apart: '/' outranks '.', so a sibling file sorts between the
two and reads as though it lived inside. The swap also makes the order
independent of the locale, which was deciding it before.
The existing cut-short test looked for 'logs/container.log', which no longer
appears, so it now checks the basename; a fourth case pins the structure rather
than the wording - a child is indented deeper than its folder and siblings sit
level.

find and du write what they already collected and only then return nonzero, so
the guards added in ce1c5b5fe were throwing away the evidence the index exists
to report. One vanished entry mid-walk blanked the whole listing: '0 file(s)',
no paths, on a tree that was mostly readable. The rescue tree is indexed while
a failed run is still tearing down, so that is the normal case, not the corner
one.
Stop resetting LISTING, fall back on SIZE only when du produced nothing, and
turn the early exit into a warning so the partial listing still prints.
The existing test could not see this: its stub find emitted nothing, so it only
covered a total failure. The new case stubs a find that prints rows and then
fails, and it fails against ce1c5b5fe.

Every caller runs this in a cleanup path: three shell teardown handlers and a
GitHub step under bash -e, none of them with a fallback. A nonzero rc therefore
aborts the caller's remaining teardown or adds a second red step on top of the
failure being rescued. Until now that could not happen only because each
internal failure path happened to be caught - a property that dies with the
next edit. A terminal 'trap exit 0' states the guarantee once and makes it
independent of the enumeration.
The failure is not hypothetical: a find that rejects -printf (BusyBox) makes
the old script exit 1, reproduced with a stub.
Collapses three walks of the same tree into one, and counts files with awk
rather than grep -c, which answers 1 on zero matches and takes the assignment
down with it under pipefail. A walk that fails now says so - it used to print
'0 file(s)', which reads exactly like an empty tree.

Of six CI failures triaged today, three were explainable only from downloaded
artifacts and two not even there: the job log carried "not converged:
docker_docker" or a bare "rc=1", while this collector drowned that same log in
compose trees, env listings and ganesha thread stacks.
diagnostics.sh switches its stdout per section with exec, so every topic lands
in its own file under the rescue directory and the log keeps one line. An
unwritable output directory degrades to stdout rather than killing the
collector - a failed mkdir would otherwise abort the script at the first
redirection, which the caller swallows with `|| true`, leaving no diagnostics
at all and no sign of it. For the same reason the collector says so when it
ends up having captured nothing.
00_one.sh hands the same directory to both collectors. The variable was scoped
to the python one, so the shell collector wrote where no artifact picks it up.
The capture grows by exactly what today's investigations went without: per-node
resolv.conf, daemon.json, listening sockets, NAT rules and a resolve probe
against the three hosts that killed builds, plus df and docker system df.
rescue_index.sh runs last and lists what was collected together with the note
that it is downloadable. The index is the one thing worth printing.
A test pins the routing against a stub docker: one file per section, no bleed
between them, a single log line, and the degrade path.
