Two issues, one PR — they are a hard conflict, not a convenience bundle. Both live in the same ~20 lines of install.sh (the pre-0.7.0 migration block and the had_install computation beside it), and #117 explicitly notes that "a single pass could address the reporting for both." Splitting them would mean two PRs editing the same lines and the same test/cli.sh block, with the second rebasing onto the first for no benefit.

Part 1 — #115: the ordering bug

had_install was computed after the migration block. The migration converts a flat pre-0.7.0 tree into versions/<flat_ver> — so the very next test, "does $DEST/versions exist and is it non-empty?", was answered by something the installer had done one line earlier. A flat host read as had_install=1, host/setup-host.sh was skipped, and the host kept every artifact the old release left behind while box --version reported the new one.

That is why the drill host ended up on 0.8.0 with a pre-#102 /usr/local/sbin/box-firewall: the operator most likely to upgrade for the SIGPIPE fix was the one who did not receive it, with the version string asserting the opposite.

The fix is the reorder, not a warning. had_install now computes before the migration block. That asks the honest question — a tree that needs migrating has by definition never been converged by this version's setup-host, so it must read 0. A genuinely versioned tree still reads 1, for the right reason: the directory it tests predates the run. The test suite pins both directions, so "fixed" and "runs setup-host unconditionally" are not confusable.

The accepted trade-off, stated plainly

A BOX_YES=1 unattended upgrade on a flat-tree host will now run setup-host, which the #66 comment (install.sh ~:384-386) explicitly cautions about — that is a real behaviour change on that path, and it was a decision, not an oversight. It is accepted because setup-host is documented and built as converging and idempotent, and because shipping a release whose host half is silently missing is the worse failure of the two. Reviewers who want to reopen this should reopen it as a decision.

The `current`-doesn't-flip finding: real, and fixed here

Triage flagged install.sh:407 — it ran $DEST/current/host/setup-host.sh, but current does not always flip. Verdict: real, reachable, and made reachable by Part 1 itself.

The mechanism: the #66 guard (~:305-312) holds the default where it is when the host has existing boxes. So on a flat-tree host with boxes, the migration points current at versions/<flat_ver>, the guard then refuses to move it — and current still names the old version when host setup runs. The installer would converge the host using the previous release's host scripts, reinstating exactly the staleness #115 is about, in the one case where the operator's live boxes make it most costly.

Before this PR the defect was latent (setup-host never ran on that path at all); Part 1 activates it. So it is not a separate concern to defer — fixing it here is what keeps Part 1 from being a fix in name only. The change is one path, $VDIR instead of $DEST/current: unambiguously the version this run installed, which is the version whose host contract we are being asked to satisfy. The sudo-missing hint on ~:399 was pointing at the same wrong path and moves with it. No follow-up issue filed — it is fixed, with its own regression test.

Part 2 — #117: the premise, corrected

The issue's premise is partly wrong, and I want that on the record rather than quietly fixed around. #117 says "the install output never names it" and "the migration is silent." It is not. install.sh names the migration twice today, before this PR:

~:158 — found a pre-0.7.0 flat install at $DEST (version $flat_ver) — migrating it into the versioned layout
~:166 — migrated: it now lives at $DEST/versions/$flat_ver (still current; your boxes are untouched)

So the event was always reported. What was genuinely missing is the lifecycle half: nothing told the operator that the old tree is now a first-class box versions entry they may keep or reap, and nothing said how. And the one line that did exist scrolls past roughly 250 lines of install output before done — true at the moment it prints, invisible by the time the install ends.

That is what this fixes: the migration line now names both ways out (keep it as a rollback target via box use <v>, or reap it via box uninstall <v>), and a migrated_from variable lets the closing done block re-state it as the last thing the operator sees. Deleting the tree automatically stays the wrong default, for the reason #117 gives: it is the only thing to roll back to, at exactly the moment that matters. No behaviour change, no reordering beyond Part 1's.

Test proof — real, end to end, fully offline

No Incus, no root, no network. test/cli.sh already drives real install.sh runs against fabricated sources; the gap was that its inst helper hardcodes BOX_SKIP_SETUP_HOST=1, which pins off the exact switch under test.

inst_setup — same helper without BOX_SKIP_SETUP_HOST, so host setup actually runs.
A stub host/setup-host.sh on SRC9 that echoes SETUP-HOST-RAN-FROM 9.9.9-drill. The marker is the proof, and because it names its version it distinguishes whether setup-host ran from which tree it ran from — which is what makes the current finding testable at all.

Assertions added:

Test	Proves
`flat upgrade: host setup RUNS over a migrated flat tree (#115)`	the fix
`versioned upgrade: ...still SKIPS host setup` + `...the stub did NOT run`	the gate still gates
`flat upgrade under boxes: setup-host runs the NEW version's script`	the `current` fix
`flat upgrade under boxes: ...the default correctly stayed put (#66)`	#66 is not weakened
`migrate:` ×3 — reap command, rollback wording, closing re-statement	#117
`migrate: a NON-migrating install stays silent about migration`	the note is conditional

Both fixes were verified to fail without them, which is the only thing that makes them regression tests:

Reverting install.sh wholesale: 4 failures, exactly the new #115 and #117 assertions.
Reverting only $VDIR → $DEST/current, with Part 1 kept: 1 failure, flat upgrade under boxes alone — isolating the second defect from the first.

Checks green: shellcheck -x per CI's exact invocation; bash test/cli.sh 484 passed, 0 failed; test/release.sh 90/0 and test/labels-reconcile.sh 19/0 unaffected; changelog-armed.sh passes.

Verdict: Approve — I agree with this as-is.

had_install computed before the pre-0.7.0 flat→versions/ migration so a migrated tree still runs setup-host (and reports what migration left). Versioned re-upgrade still skips. Offline fixture coverage for flat + boxes-held cases. CI green. No blockers.

Verdict: Approve.

I read install.sh in full at head 3fe589d, both linked issues, and re-ran the suites locally: test/cli.sh 484 passed, 0 failed; test/release.sh 90 passed, 0 failed; shellcheck -x install.sh clean. I also independently verified the regression claim by reverting install.sh to the parent commit (15b67d9) and re-running test/cli.sh: 5 failures, all of them the new #115/#117 assertions — so the tests genuinely pin the fix, they are not vacuous. (Footnote: the PR body says a wholesale revert produces 4 failures; I measured 5 — flat upgrade under boxes: setup-host runs the NEW version's script also fails on wholesale revert, since setup-host never runs at all on that path. Harmless narrative discrepancy, mentioning it only for the record.)

Why the core fix is right

install.sh:160-163 now computes had_install before the migration block at install.sh:179-197. This is the correct question, and I verified all three tree states behave:

Genuinely fresh host (no bin/box, no versions/): had_install=0, setup offered — unchanged from before, same code path the flat case exercises.
Pre-0.7.0 flat tree: versions/ does not exist at the time of the test, so had_install=0 and setup-host runs after the migration — the #115 fix, pinned by flat upgrade: host setup RUNS over a migrated flat tree (#115) (test/cli.sh:1839-1840).
Post-migration / genuinely versioned tree: versions/ predates the run, had_install=1, setup skipped with the box setup-host pointer at install.sh:422 — pinned in both directions by the versioned upgrade pair (test/cli.sh:1848-1851), which is what keeps "fixed" distinguishable from "runs setup-host unconditionally."

The $VDIR fix (install.sh:429, install.sh:437) is the part I scrutinized hardest, because Part 1 is what makes it reachable: on a flat host with live boxes, the #66 guard at install.sh:326-333 holds current at the migrated old version, so $DEST/current/host/setup-host.sh would have converged the host with the previous release's scripts — or, as the test comment at test/cli.sh:1856-1859 correctly notes, found no script at all, since the flat fixture carries no host/ dir. $VDIR is unambiguously the tree this run installed. The flat upgrade under boxes pair (test/cli.sh:1862-1865) proves both the new-version marker and that the #66 default stayed put. The sudo-missing hint at install.sh:429 moving to the same path is correct and easy to miss — good catch including it.

The #117 half

Detection is precise: migrated_from (install.sh:178,196) is set only inside the migration branch, whose guard [ -e "$DEST/bin/box" ] && [ ! -d "$DEST/versions" ] (install.sh:179) cannot fire on a fresh host (no bin/box) or a versioned one (versions/ exists) — no false positives, and the NON-migrating install stays silent assertion (test/cli.sh:1814-1815) pins that. The messages name the actual leftover path (versions/$flat_ver) and both ways out (box use / box uninstall), at the migration (install.sh:193-195) and again after done (install.sh:460-463). Nothing destructive happens to the leftover — name-and-continue, with auto-delete explicitly rejected for the rollback-target reason #117 itself gives. That is the right default.

Migration idempotency holds: once migrated, versions/ exists and the guard cannot re-fire; a re-run converges as a normal versioned install. (The narrow crash window inside the two-rename migration itself predates this PR and is unchanged by it.)

The stated trade-off

Accepting that a BOX_YES=1 unattended upgrade on a flat host now runs setup-host is the right call, argued honestly in the PR body: setup-host is built to converge, and a release whose host half silently never lands (#115's exact failure — 0.8.0 reported while the pre-#102 box-firewall keeps taking the no-UFW branch) is strictly worse. The decision is on the record in the comment at install.sh:146-159 and the CHANGELOG entry, where a future reviewer can reopen it.

Non-blocking observations

Same-version reinstall over a flat tree (new_ver == flat_ver, e.g. re-piping the 0.6.0 installer over a flat 0.6.0): the migration runs, $VDIR is the migrated old tree, had_install=0, and setup-host would execute from a tree that may have no host/setup-host.sh. The failure mode is the graceful warn at install.sh:440-441, so nothing breaks — just noting the edge exists. Not worth code.
A dedicated fresh-host inst_setup assertion (no prior tree at all) would complete the matrix, but the fresh path is byte-identical to the flat path's gate and unchanged by this PR — genuinely optional.

Nice work — the test proof discipline here (marker names the version, reverts verified to fail, the conditional-silence assertion) is exactly what makes a fix in this file trustworthy.

Round passed — three approvals, no blockers. Thanks all.

Both of @claude-bot-andresmgsl's observations are ones I agree with and am deliberately not acting on:

Same-version reinstall over a flat tree (new_ver == flat_ver) — the edge is real: migration runs, $VDIR is the migrated old tree, had_install=0, and setup-host executes from a tree that may carry no host/setup-host.sh. It lands on the graceful warn at install.sh:440-441, so the failure mode is a message rather than a break. Agreed it is not worth code.
A fresh-host inst_setup assertion — the fresh path is byte-identical to the flat path's gate and unchanged by this PR, so it would pin something this PR does not move.

Neither is filed, on the principle that an issue nobody will act on is worse than a review comment that stays findable on the PR.

Worth restating for whoever reads this at merge time, since it is the load-bearing part: the $VDIR fix is not incidental to Part 1 — Part 1 activates it. Before this PR, install.sh:407 running from $DEST/current was harmless because setup-host never ran on that path at all. Making it run is exactly what turns the #66 guard (which holds current at the migrated old version when boxes exist) into a live defect: the host would converge with the previous release's scripts, reinstating #115's staleness in its most expensive case. Shipping Part 1 without the $VDIR change would have been a fix in name only. The isolating revert — Part 1 kept, $VDIR reverted → exactly one failure, flat upgrade under boxes — is what proves that empirically rather than by argument.

Handing to the maintainer: requesting @danmt for the human round.

Rebased onto main after #126 merged. CHANGELOG.md only — install.sh and test/cli.sh rebased clean, so the $VDIR fix and its fixtures are byte-identical to what you approved at 3fe589d.

The conflict needed a human and the resolver said so. Both sides carried ### Fixed — main's (now holding #116's and #122's entries, merged as #118 and #126) and this PR's three. It refused with sides share section(s) {Fixed}; resolved by hand into one ### Fixed heading holding all six bullets, ### Changed untouched above.

Verification, including the structural check that content guards cannot see:

heading set vs main         identical
markers across commits      none
bash test/cli.sh            484 passed, 0 failed
bash test/release.sh        120 passed, 0 failed
shellcheck -x                clean (CI globstar block)
changelog-armed.sh           pass

That last line is #126's guard, now live on main, running against this branch — first real use since it landed.

On the two non-blocking observations (@claude-bot-andresmgsl) — both left alone deliberately, not overlooked:

Same-version reinstall over a flat tree. Real edge, and your own analysis is why I am not touching it: the failure mode is the graceful warn at install.sh:440-441, so nothing breaks. Adding code for a path that already degrades correctly would be more surface than the edge is worth.
A fresh-host inst_setup assertion. Agreed it would complete the matrix, and agreed it is out of scope here — the fresh path is byte-identical to the flat path's gate and unchanged by this PR. Worth its own small PR rather than smuggling coverage of an untouched path into a fix.

Re-requesting all three — the push moved head, so approvals bound to 3fe589d are stale regardless of content.

Rebased onto `main` after #126 merged. `CHANGELOG.md` only — `install.sh` and `test/cli.sh` rebased clean, so the `$VDIR` fix and its fixtures are byte-identical to what you approved at `3fe589d`. **The conflict needed a human and the resolver said so.** Both sides carried `### Fixed` — main's (now holding #116's and #122's entries, merged as #118 and #126) and this PR's three. It refused with `sides share section(s) {Fixed}`; resolved by hand into one `### Fixed` heading holding all six bullets, `### Changed` untouched above. Verification, including the structural check that content guards cannot see: ``` heading set vs main identical markers across commits none bash test/cli.sh 484 passed, 0 failed bash test/release.sh 120 passed, 0 failed shellcheck -x clean (CI globstar block) changelog-armed.sh pass changelog-monotonic.sh pass ``` That last line is #126's guard, now live on `main`, running against this branch — first real use since it landed. **On the two non-blocking observations** (@claude-bot-andresmgsl) — both left alone deliberately, not overlooked: 1. *Same-version reinstall over a flat tree.* Real edge, and your own analysis is why I am not touching it: the failure mode is the graceful `warn` at `install.sh:440-441`, so nothing breaks.

Verdict: Approve — I agree with this as-is.

Tip b1968da is the same fix rebased onto main after #126. Prior approve was at 3fe589d.

What holds

had_install before the pre-0.7.0 migration — a flat host no longer looks already versioned and skips setup-host.
Host setup runs the just-installed tree, not $DEST/current (which can still name the old version when boxes hold the default).
Migration names the lifecycle — keep via box use or reap via box uninstall.
CHANGELOG under ## Unreleased ### Fixed with main's entries; heading set matches main (single ## 0.8.0).

Accepted trade-off (unattended flat upgrade runs setup-host) still stated; CI green. No remaining blockers.

✅ Approved — I agree with all of this, no concerns.

Re-approving after the rebase to head b1968da. My 3fe589d approval covered the substance; this round I verified the rebase itself rather than re-arguing it:

"Rebased clean" holds, checked mechanically: I diffed the PR's patch at 3fe589d against the patch at b1968da — for install.sh and test/cli.sh they are identical except for hunk offsets and blob hashes (the head-to-head file diff shows only main's own staging→staging-box renames, which is exactly what a clean rebase picks up). The $VDIR fix and its fixtures are the same bytes I approved.
The hand-resolved CHANGELOG conflict is right: one ### Fixed under ## Unreleased (line 62) now holds main's entries plus this PR's three bullets, ### Changed untouched above, and the ## heading set is identical to main's — so the #126 monotonicity guard has nothing to object to, and indeed passes.
Re-ran everything at b1968da: test/cli.sh 484 passed / 0 failed, test/release.sh 120/0, shellcheck -x install.sh clean, changelog-armed.sh and changelog-monotonic.sh both pass — matching the numbers in the rebase comment.

My two non-blocking observations from last round (same-version flat reinstall; fresh-host inst_setup assertion) were addressed by explicit, reasoned non-action, which I accept — nothing new to raise.

Verdict: I agree with everything and have no additional feedback.\n\nRe-evaluated the complete current diff at b1968dab after the rebase. The installer ordering and $VDIR setup-host path remain correct, the migration guidance is conditional and actionable, the regression coverage exercises both run and skip paths, and all current checks pass.
