This directory is what gets packaged into localhost.apkovl.tar.gz and
baked into adaptiveos-vN.iso. It had drifted out of sync with the real
project (root/shell-project/ had gone missing entirely at some point
after being written earlier this session -- cause unconfirmed, Desktop
is a plausible sync-related suspect but not verified) and separately
carried a stale, pre-fix copy of fx.sh.
Current contents:
etc/profile.d/adaptive-loop.sh -- disk-persists p AND p.trace
(fx()'s fix-provenance record)
across reboot, two separate 1MB
blocks on the attached state disk
etc/profile.d/adaptive-setup.sh -- unchanged, network/git/fzf bring-up
root/shell-project/ -- synced from space.seodr.ovh/
Daveswo/self-healing-autopoietic-
shell @ 3c4947e (main), plus three
deployment-only files not in that
repo: contrib/fx/builtin-fixes.txt,
contrib/fx/sources.d/15-builtin-
fixes.sh, contrib/heal/heal.sh
Verified byte-identical to what's actually embedded in the currently
shipping adaptiveos-v6.iso before this commit (full recursive diff),
and every .sh file passes `sh -n`.
.gitattributes (text=auto eol=lf) added to prevent the CRLF corruption
that hit the canonical repo earlier this session from recurring here.

# Self-diagnosis source: many CLIs print their own corrected invocation
|
|
# in their error output (git's --set-upstream hint, apt's "did you
|
|
# mean", etc.).
|
|
#
|
|
# IMPORTANT: this must NOT cache the literal suggested line -- that
|
|
# reintroduces the exact-key staleness problem (e.g. "git push" learned
|
|
# once on branch A silently misapplies its captured --set-upstream on
|
|
# branch B, and B never actually gets pushed). Instead it emits a
|
|
# function that shadows the whole program and re-derives the suggestion
|
|
# from *live* output on every call, the same trick proven to generalize
|
|
# correctly across branches/arguments in practice. One taught fix this
|
|
# way covers every future self-diagnosing failure from that program, not
|
|
# just the one instance that happened to trigger the teaching prompt.
|
|
#
|
|
# The emitted function runs on every future call to that program for
|
|
# the rest of the session, so its own internal extraction is one awk
|
|
# pass, not a grep|sed|tail chain -- three fewer forks on every failure
|
|
# it ever handles, not just this first one.
