Important

This PR is stacked on #128 and cannot merge before it.
It extends snapshot_pristine and storage_driver, which exist only on feat/pristine-snapshot — they are not on main. Because the PR targets main, GitHub's diff here carries #128's commit as well as mine. My change is 762e977 alone; review it with git diff 982ee0e..HEAD, or read the second commit in the commit list.
Merge order: #128 → this. Labeled blocked until then. If review changes #128's helpers under me, I will rebase; I am not fixing #128 from here.

Closes #130. Child of heavy-duty/rig#62, and the half #104 floated and #128 deliberately deferred rather than dropped.

#128 takes the rollback floor: pristine, the guest after cloud-init and before rig converged anything. This takes the checkpoint one step later, at the other end of the same hook — after rig bootstrap <role> has run and box has watched it succeed. At that instant the box is converged and not yet touched.

box restore work bootstrapped   # keep the tenant role, undo what you did to it
box restore work pristine       # throw the tenant role away too

Those are different products, and the second one is not a substitute for the first. pristine answers "start this box over". bootstrapped answers "I broke my work, not the role" — which is the more common bad day, and whose only alternative today is a ~10-minute re-mint. #128's own argument for deferral was that bootstrapped "competes with box snapshot <box> <label>, which already exists". That is true and it is not enough: the moment worth marking is the last instruction of a hook that runs unattended, and nobody is at the console to type box snapshot there. Same reason pristine is automatic.

The diff in cmd_new is one call and one added paragraph on the failure path. Everything below is the two questions #130 exists to settle, plus the helper call it asked for.

Question 1 — the blank-template asymmetry

Resolved: accept it, and make the asymmetry the load-bearing rule rather than an exception to one. A hookless box gets nothing, and that is a chosen answer.

The worry is real: pristine is deliberately unconditional within a fresh mint so box restore <box> pristine means one thing on every box box mints, and a conditional second label breaks that symmetry. But the symmetry it breaks is the wrong invariant to preserve, because the two labels are not the same kind of fact:

pristine marks a MOMENT. Every fresh mint has it — cloud-init finished, rig has not started — whether or not a template names a role. Unconditional is correct because the moment is unconditional.
bootstrapped marks an EVENT — "a tenant role converged, and nothing has happened since." A blank box has no such event.

So the label tracks the event, not the mint, and marking a blank box anyway fails in one of two ways depending on what you'd mean by it:

If it means "the state after mint", it is pristine byte for byte — nothing runs between them on a blank box — at twice the disk cost. That is exactly the doubling #128's dir detection exists to refuse, paid for zero information.
If it means what it says, it asserts a convergence that never happened. That is the same lie #128 refused on the --from clone path, where inventing a pristine would have labelled worked-in state as pristine Debian. The clone reasoning applies here unchanged: a label that promises something the disk cannot deliver is worse than no label, because nothing at runtime ever says so.

The upside of accepting the asymmetry is that presence becomes information: a box carrying bootstrapped had a role and box saw it converge. That is a fact worth being able to read off box info, and it only stays a fact if the label is never minted where the event did not happen.

The cost is that operators must not read it in the other direction — which is question 2's problem, and is handled there.

Question 2 — the hand-re-run case

Resolved: take no mark, hand the operator the exact command at the exact moment, and pin the label as one-directional on every surface so absence can never be read as a claim.

#130 states the objection at full strength and I want to restate it rather than soften it:

A mark that is reliably missing on the interesting cases is worse than no mark, because its presence elsewhere implies a coverage it does not have.

That is right, and it rules out the lazy answer ("leave it absent, mention it in the docs"). It does not, I think, rule out absence itself. It rules out absence that goes unsaid, and absence that anything is entitled to interpret. So the resolution has three parts, and only all three together answer it.

(a) box cannot honestly take the mark after a by-hand re-run, and should not pretend otherwise. cmd_new's failure path dies. The operator then opens box shell, fixes whatever broke, and re-runs sudo rig bootstrap <role> inside a shell that box is not in, does not supervise, and gets no exit code from. There is no moment at which box learns the role converged. Options I considered and rejected:

Poll for /etc/rig/role and mark when it appears. The marker is written by bootstrap-tenant.sh at the end of a run, but "the marker exists" is not "the run finished cleanly", and box would be marking on a guess. It would also mean a background watcher outliving the mint, which box new has no business starting.
Add a box bootstrap <box> verb that wraps the re-run so box can watch it. This is a genuinely defensible design and I am open to being pushed onto it. I did not take it because it grows the CLI surface to solve a mark's problem, it duplicates rig bootstrap's own interface (and would have to track its flags), and the failure it exists for is the one where rig itself was unhappy — wrapping it in another layer is not obviously what an operator wants while debugging. If reviewers want it, it is a separate issue, not a wider version of this one.
Take the mark at box shell exit. Marks on an unrelated trigger; a shell exits for a hundred reasons.

(b) So say it where the operator is standing. The hook-failure message is the one place they are certainly looking, and it now carries the missing half:

box: rig bootstrap claude FAILED in work.
box: the box is up and the seed is intact — the role converges, so re-run it:
  box shell work    # then: sudo rig bootstrap claude
box: no 'bootstrapped' mark was taken — box only marks a hook it watched succeed,
  and a by-hand re-run happens in a shell it does not watch. Take it yourself once
  the role converges, at the moment it is true:
  box snapshot work bootstrapped
box: 'box restore work pristine' is still there if you would rather start the role over.

This is the point where #128's "it competes with box snapshot" argument becomes the answer instead of the objection. The by-hand verb already exists and is exactly right here, because the operator — unlike box — does know when the role converged. box's job is to hand it over at the right second, not to guess.

(c) The residual is that an operator may ignore the hint, so absence must never be load-bearing. This is the part that actually neutralises #130's objection, and it is a documentation contract, not a note:

Presence means the mint-time hook converged and nothing has touched the box since. Absence means nothing at all — a blank template, a dir pool, BOX_SNAPSHOT_BOOTSTRAPPED=0, or a role converged by hand.

box help restore says it in those words, box help new and box help snapshot say it in theirs, and the README and design doc both list the four ways a converged box can legitimately have no mark. box info <box> remains the only thing that tells you what a box actually has. A test greps for absence proves NOTHING so a future edit cannot quietly soften it into a hint — the same shape as #128's not a backup guard, and for the same reason.

The stance this commits box to: nothing in box may ever treat a missing bootstrapped as evidence a box is unconverged. That is stated in bin/box's comment above snapshot_bootstrapped so the next feature that wants to read the label finds the rule before it writes the bug.

The helper: generalise the mechanism, not the prose

#130 called this an implementation call. Mine: one shared policy function, two thin wrappers — not one stringly-parameterised function, and not a duplicated second one.

snapshot_pristine splits cleanly into two halves that want opposite treatment.

The mechanism is identical for both marks and should exist once: read the opt-out → read storage_driver → refuse on dir → note an unreadable pool and proceed → create → warn without failing the mint. That last clause is the one I most want to exist in a single place. A duplicated never-fatal contract is the classic way one copy quietly grows a set -e interaction or an early return 1 that fails a good mint, and nothing would notice until a mint failed over a checkpoint. One function, one thing to review, and a third mark inherits it for free.

The prose is not shared and should not be forced to be. pristine and bootstrapped name different moments and deserve different sentences; a single function taking five message strings as arguments would be a worse artifact than two four-line wrappers, and the call sites would be unreadable.

So:

snapshot_mark <instance> <name> <label> <enabled> <what-this-state-is>

snapshot_pristine()     { snapshot_mark "$1" "$2" pristine     "${BOX_SNAPSHOT_PRISTINE:-1}"     "..."; }
snapshot_bootstrapped() { snapshot_mark "$1" "$2" bootstrapped "${BOX_SNAPSHOT_BOOTSTRAPPED:-1}" "..."; }

Two details worth flagging:

The opt-out variable name is derived from the label (BOX_SNAPSHOT_ + upper-cased label), so the skip message can never drift from the knob the operator actually has to set. A test drives BOX_SNAPSHOT_PRISTINE=0 against snapshot_bootstrapped and asserts the mark is still taken — one label's knob must not silently disable the other's.
snapshot_pristine keeps its exact name, signature and observable output. That is deliberate: every one of #128's ~15 driven assertions still runs against it unchanged, so this refactor does not weaken the approved PR's test surface. The one line of #128's tests I touched is its awk extraction, which now also pulls snapshot_mark — otherwise the extracted snapshot_pristine would call a function that isn't there. That is the whole of my footprint inside #128's work.

The `dir` skip, which #130 specifically flagged

#130 notes that a second automatic mark doubles the disk-cost objection #128's driver detection exists to answer. It does, and the answer is that the skip is in snapshot_mark, so it covers both marks by construction: a dir-pool host is not asked to pay for one full root copy per mint, let alone two. The skip is as loud for bootstrapped as for pristine and names the by-hand command.

One thing that is actually better here than for pristine: the dir skip's advice, box snapshot <box> bootstrapped, stays correct indefinitely. The converged-and-untouched state persists until the operator changes something. pristine's equivalent advice is only true for the few seconds before rig starts. Not a change to #128 — just worth noting the same sentence carries more weight on this label.

Durability — unchanged, and restated rather than referenced

Every new surface repeats both caveats in full instead of pointing at the pristine paragraph above it, because an operator reading about bootstrapped may not have read the other one:

It is an undo, not a backup. box rm deletes a box and every snapshot it has. box export is the only state that outlives the box. #128's test grepping help snapshot for "not a backup" still passes — I did not touch that sentence.
It cannot reach off-box state. A tailnet device record, a GitHub runner registration, a pushed commit: rig#62's whole finding, and no filesystem rollback undoes any of it. help restore and the README name it for bootstrapped specifically, and a test pins cannot undo anything in help restore.

Tests

25 new assertions in test/cli.sh, house style, daemon-free.

Position and gating, pinned by line order. The two facts are opposite in shape from pristine's and both must hold at once:

assertion	why
the mark orders after `incus exec … rig bootstrap "$T_BOOTSTRAP_ROLE" </dev/null`	earlier and it is `pristine` wearing a name that claims convergence
the mark is gated on `[ -n "$T_BOOTSTRAP_ROLE" ]`	the blank asymmetry, chosen — the exact inverse of #128's "is unconditional" guard, which still passes
the failure branch's `die` orders before the mark	a failed hook is structurally unable to reach it
the failure message contains `box snapshot $name bootstrapped`	question 2's answer, pinned so it cannot be dropped
the clone branch contains no `snapshot_bootstrapped`	#128's clone extraction, reused
`grep -c 'incus snapshot create' bin/box` is exactly 2	the policy is called, not copy-pasted (the other is `cmd_snapshot`'s by-hand verb, deliberately fatal)

The policy half is driven, not grepped — storage_driver + snapshot_mark + snapshot_bootstrapped are extracted and executed against a stubbed incus, the same box_tier/pris() pattern #128 uses: btrfs takes the mark and names the restore command, dir skips it and never reaches snapshot create, an unreadable pool takes it and says what it assumed, BOX_SNAPSHOT_BOOTSTRAPPED=0 skips it, BOX_SNAPSHOT_PRISTINE=0 does not, and a refused snapshot warns and still returns 0.

Proven to bite. Six breaks, each observed RED, each reverted:

break	result
moved the mark to before the hook exec	2 RED (`orders AFTER the rig bootstrap hook`, `a FAILED hook dies before ever reaching the mark`)
made the mark unconditional (out of the `T_BOOTSTRAP_ROLE` guard)	3 RED (the two above + `the mark IS gated on a tenant role`)
changed the `dir` skip to a driver name that never matches	6 RED — 3 of them #128's, which is the point of sharing the function
replaced the call with an inline `incus snapshot create` (copy-paste the policy)	5 RED, incl. `exactly one auto-mark policy`
dropped `box snapshot $name bootstrapped` from the failure message	1 RED
softened `Its absence proves NOTHING` to `Its absence is a hint`	1 RED

What this does and does not prove

Plainly: the stub tests prove the control flow, and nothing here proves the feature end to end.

CI's rehearsal job will almost certainly not exercise this path at all. It mints blank on a real Incus daemon — and blank is precisely the template that, by this PR's own decision, runs no hook and takes no mark. So where #128 could point at a rehearsal log showing incus snapshot create actually issued, I cannot. A green rehearsal here proves I did not break the existing mint; it does not prove bootstrapped was ever taken on a real daemon. I would rather say that outright than let a green check imply coverage.
That box restore <box> bootstrapped returns a worked-in box to converged-and-untouched is untested end to end. It is the feature's whole claim. The drill is: mint a claude box, work in it, restore, and look.
The dir skip on a real dir host is stub-only, inherited from #128 — every CI host has btrfs.
The hook-failure path is pinned structurally (the die precedes the mark) but has never been run with a failing hook, here or in CI.

One thing the rehearsal did prove, confirmed from the log on this branch (run 29737650371): the refactor is live-clean. Grepping it finds

box: marking 'pristine' — the guest after cloud-init, before rig converges anything.

and no marking 'bootstrapped' line at all — which is exactly what this PR predicts, since the rehearsal mints blank. So snapshot_mark really did run against a real daemon, through the real box-net profile and pool, and produced #128's behaviour byte for byte; and the blank-template decision is observably in force rather than merely asserted. It is still not evidence that bootstrapped was ever taken anywhere.

Not a change to #128 — just worth noting the same sentence carries more weight on this label. ## Durability — unchanged, and restated rather than referenced Every new surface repeats both caveats in full instead of pointing at the `pristine` paragraph above it, because an operator reading about `bootstrapped` may not have read the other one: - **It is an undo, not a backup.** `box rm` deletes a box and every snapshot it has. `box export` is the only state that outlives the box. #128's test grepping `help snapshot` for "not a backup" still passes — I did not touch that sentence. - **It cannot reach off-box state.** A tailnet device record, a GitHub runner registration, a pushed commit: rig#62's whole finding, and no filesystem rollback undoes any of it. `help restore` and the README name it for `bootstrapped` specifically, and a test pins `cannot undo anything` in `help restore`. ## Tests 25 new assertions in `test/cli.sh`, house style, daemon-free. **Position and gating, pinned by line order.** The two facts are opposite in shape from `pristine`'s and both must hold at once: | assertion | why | |---|---| | the mark orders **after** `incus exec … rig bootstrap "$T_BOOTSTRAP_ROLE" </dev/null` | earlier and it is `pristine` wearing a name that claims convergence | | the mark **is gated** on `[ -n "$T_BOOTSTRAP_ROLE" ]` | the blank asymmetry, chosen — the exact inverse of #128's "is unconditional" guard, which still passes | | the failure branch's `die` orders **before** the mark | a failed hook is structurally unable to reach it | | the failure message contains `box snapshot $name bootstrapped` | question 2's answer, pinned so it cannot be dropped | | the clone branch contains no `snapshot_bootstrapped` | #128's clone extraction, reused | | `grep -c 'incus snapshot create' bin/box` is exactly **2** | the policy is called, not copy-pasted (the other is `cmd_snapshot`'s by-hand verb, deliberately fatal) | **The policy half is driven, not grepped** — `storage_driver` + `snapshot_mark` + `snapshot_bootstrapped` are extracted and executed against a stubbed `incus`, the same `box_tier`/`pris()` pattern #128 uses: btrfs takes the mark and names the restore command, `dir` skips it and never reaches `snapshot create`, an unreadable pool takes it *and says what it assumed*, `BOX_SNAPSHOT_BOOTSTRAPPED=0` skips it, `BOX_SNAPSHOT_PRISTINE=0` does **not**, and a refused snapshot warns and still returns 0. **Proven to bite.** Six breaks, each observed RED, each reverted: | break | result | |---|---| | moved the mark to before the hook exec | 2 RED (`orders AFTER the rig bootstrap hook`, `a FAILED hook dies before ever reaching the mark`) | | made the mark unconditional (out of the `T_BOOTSTRAP_ROLE` guard) | 3 RED (the two above + `the mark IS gated on a tenant role`) | | changed the `dir` skip to a driver name that never matches | 6 RED — **3 of them #128's**, which is the point of sharing the function | | replaced the call with an inline `incus snapshot create` (copy-paste the policy) | 5 RED, incl. `exactly one auto-mark policy` | | dropped `box snapshot $name bootstrapped` from the failure message | 1 RED | | softened `Its absence proves NOTHING` to `Its absence is a hint` | 1 RED | ### What this does and does not prove Plainly: **the stub tests prove the control flow, and nothing here proves the feature end to end.** - **CI's `rehearsal` job will almost certainly not exercise this path at all.** It mints `blank` on a real Incus daemon — and `blank` is precisely the template that, by this PR's own decision, runs no hook and takes no mark. So where #128 could point at a rehearsal log showing `incus snapshot create` actually issued, I cannot. A green rehearsal here proves I did not break the existing mint; it does not prove `bootstrapped` was ever taken on a real daemon. I would rather say that outright than let a green check imply coverage. - **That `box restore <box> bootstrapped` returns a worked-in box to converged-and-untouched** is untested end to end. It is the feature's whole claim. The drill is: mint a `claude` box, work in it, restore, and look. - **The `dir` skip on a real `dir` host** is stub-only, inherited from #128 — every CI host has btrfs. - **The hook-failure path** is pinned structurally (the `die` precedes the mark) but has never been *run* with a failing hook, here or in CI. **One thing the rehearsal did prove, confirmed from the log on this branch ([run 29737650371](https://github.com/heavy-duty/box/actions/runs/29737650371)):** the refactor is live-clean. Grepping it finds ``` box: marking 'pristine' — the guest after cloud-init, before rig converges anything. ``` and **no `marking 'bootstrapped'` line at all** — which is exactly what this PR predicts, since the rehearsal mints `blank`. So `snapshot_mark` really did run against a real daemon, through the real `box-net` profile and pool, and produced #128's behaviour byte for byte; and the blank-template decision is observably in force rather than merely asserted. It is still not evidence that `bootstrapped` was ever taken anywhere. ## Checks - `bash test/cli.sh` — **523 passed, 0 failed** (498 on #128's tip; 25 new) - `bash test/labels-reconcile.sh` — **19 passed, 0 failed** - `bash test/release.sh` — **90 passed, 0 failed** - `shellcheck -x` over CI's exact globstar list (`bin/* **/*.sh`, 15 files) — clean - `.github/scripts/changelog-armed.sh` — passes - `CHANGELOG.md` edited by **insertion only**, a new bullet above the `pristine` one inside the existing `## Unreleased` → `### Added`. `git diff -- CHANGELOG.md | grep -c '^-[^-]'` → **0** (the #122/#126 failure mode). - `git diff 982ee0e..HEAD --name-only` → `CHANGELOG.md README.md bin/box docs/box-design.md test/cli.sh`, and the only deletions are the `snapshot_pristine` body it refactors and the one `awk` line in #128's test. Nothing else of #128's is touched. ## Docs `README.md` gains `### bootstrapped — the same undo, one step later` directly under #128's `pristine` section, including the four legitimate reasons a mark can be absent; the command table's `box restore` entry names it. `docs/box-design.md` gets the moment-vs-event distinction in design register. `box help new` / `help snapshot` / `help restore` each carry the part an operator meets on that verb, and each restates the durability and off-box caveats in full.

🔧 Changes requested — I agree with most; feedback below.

Reviewed 762e977 alone, per the stacking note. The design answers to #130's two questions hold: moment-vs-event is the right frame for the blank asymmetry, the three-part answer to the hand-re-run case (no guessed mark, the command handed over at the failure site, absence pinned as meaning nothing) is the honest resolution, and the snapshot_mark split — one mechanism, per-label prose — puts the never-fatal contract in exactly one place, with the shared-dir-skip breakage (6 RED, 3 of them #128's) proving the sharing is load-bearing. The "what this does not prove" section is the right kind of candor. Verified on this head: bash test/cli.sh → 523 passed, 0 failed. One point:

bin/box:1421 — box: 'box restore $name pristine' is still there if you would rather start the role over. is unconditional, but three mints that reach this line have no pristine mark, all by this stack's own design: a dir-pool host (skipped), BOX_SNAPSHOT_PRISTINE=0, and a refused create (warned, mint continued). On a dir host it is every hook failure, and the operator standing at the one moment this message exists for copy-pastes a restore that errors. That is the failure mode this PR's question-2 answer is built to refuse — a promise the disk cannot deliver, on the exact surface designed to "say it where the operator is standing". Mechanical fix either way: track whether the mark was taken (snapshot_mark returns 0 on every path, so cmd_new currently cannot know — a variable or a distinguishing return works), or make the sentence honest without state: "if this mint took a 'pristine' mark (it said so above), 'box restore $name pristine' starts the role over." A test pinning the conditional (or the hedged wording) keeps it from regressing to the bare claim.

My two #128 points stand over there and neither lands in code this commit moves — storage_driver's probes and the clone-narration grep -q are untouched — so a #128 fix rebases clean under this.

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

Tip 762e977 (stacked on #128) marks the post-hook checkpoint #128 deliberately deferred. Reviewing this commit alone.

What holds

snapshot_mark is the right split. Shared never-fatal / dir-skip / opt-out policy in one place; thin wrappers own different prose. A third mark inherits the contract instead of re-implementing it subtly wrong.
Event vs moment asymmetry is load-bearing, not a wart. pristine is unconditional (every mint has the moment); bootstrapped only after a hook box ran and watched succeed. Blank / failed / by-hand paths correctly get none rather than a lying or byte-identical duplicate.
Failure path hands over box snapshot … bootstrapped instead of inventing a mark for a shell re-run box does not watch — same honesty rule as the clone path on #128.
Presence is information; absence proves nothing — documented on every surface and pinned in tests.

Nits / optional

None that block. Stacked on #128; merge order is correct.

Verdict: I have feedback.

bin/box presents box restore $name pristine as available after a bootstrap-hook failure, but this path is also reached when no pristine snapshot exists: dir storage, BOX_SNAPSHOT_PRISTINE=0, or a failed snapshot creation. That makes the recovery guidance fail precisely when the operator needs it. Please either track whether pristine was actually created or qualify the message (for example, “if this mint took a pristine mark”), and pin that behavior with a test.

Round reply — @claude-bot-andresmgsl, @codex-bot-andresmgsl, @grok-bot-andresmgsl

You both found the same line independently, which is usually a sign it is real. It was. Fixed in 7d5bfa4.

The bug. cmd_new's hook-failure path offered box restore $name pristine unconditionally, and three mints reach that line with no pristine mark, all by this stack's own design: a dir pool (skipped, no CoW), BOX_SNAPSHOT_PRISTINE=0, and a create incus refused (warned, mint continued). On a dir host that is every hook failure — so the operator standing at the one moment the message exists for copy-pastes a command that errors.

Why the obvious fix does not work. Neither of you assumed it would, but it is worth stating: this cannot be read off the return status. The never-fatal contract makes snapshot_mark return 0 on all four paths on purpose, so if snapshot_mark ... cannot tell a mark that exists from one that does not — and teaching it to would put the mint's success at the mercy of a checkpoint, which is exactly what that contract exists to prevent. @claude-bot-andresmgsl's framing — "a variable or a distinguishing return works" — is right, and of the two only the variable keeps the contract intact.

The fix. The fact is recorded rather than inferred: marks accumulates the labels snapshot_mark actually created, and mark_taken <label> answers the only question a rollback offer may ask. Per-label, so one mark never answers for another.

Worth naming what this really was: the message one line earlier already makes this exact refusal when it declines to invent a bootstrapped it never watched. Offering a pristine the disk does not have is the same lie, on the same screen, two lines apart. The principle was already here; it just had not been applied to the restore offer sitting under it.

On pinning it with a test (@codex-bot-andresmgsl) — done, per path rather than once, because the three no-mark paths fail differently and a single case would let the other two regress silently:

drive	asserts
btrfs, created	`TAKEN`
`dir` pool	`ABSENT`
`BOX_SNAPSHOT_*=0`	`ABSENT`
create refused	`ABSENT`
`marks=" bootstrapped "`	`pristine` is `ABSENT` — no bleed between labels
static	the call site is inside `if mark_taken pristine`

And I verified the tests fail for the right reason rather than trusting six green lines: mutation-tested both halves. Removing the recording (marks="$marks $label") fails "a mark that WAS created is remembered"; un-gating the offer fails "the restore offer is GATED". Both restore clean.

test/cli.sh 531/531, shellcheck -x clean.

Not re-requesting review yet, deliberately. This PR is still stacked on #128 and CONFLICTING against main. #128 is mid-round and mergeable; the moment it lands I will rebase this onto it — which changes the head again and would stale any verdict given now. Re-requesting after the rebase costs one round instead of two. The blocked label stays until then.

#128 has landed (64127b3), so this is unblocked, rebased onto main, and down to its own two commits — 050c909 (the feature) and 4c595eb (the review fix from the last round). blocked cleared; re-requesting the panel.

#128's two commits were carried here only because this branch was cut from them. With their content on main the replays were no-ops and they dropped out, so the diff is finally just this PR's work.

One conflict, in CHANGELOG.md, and I did not resolve it purely positionally. main now carries #104's pristine bullet under ### Added, and this PR's bootstrapped bullet is the sequel to it — the mark that keeps the tenant role where pristine throws it away. Left where the merge put it, the two would have been separated by #103's provenance entry. They now read in the order the features compose: mint stamp → pristine → bootstrapped. No prose altered, no heading rewritten; changelog-monotonic.sh confirms all 4 headings at the new merge base survive.

The check that matters after a rebase this deep — the whole suite, not the conflicted file:

suite	result
`test/cli.sh`	606/606
`test/labels-reconcile.sh`	72/72
`test/release.sh`	134/134
`shellcheck -x` over `bin/* */.sh`	clean
changelog armed + monotonic	green

And specifically: all 6 of last round's rollback: assertions survived the rebase and still pass — the ones pinning that the pristine rollback is only offered when the mark exists, per path (created / dir-skip / knob / refused / no bleed between labels) plus the static gate check. A rebase that quietly dropped the fix for a bug three reviewers found would be the worst possible outcome here, so it is asserted rather than assumed.

Nothing else changed since the round: 4c595eb is the same fix you have already seen, replayed unmodified.

Verdict: I agree with everything and have no additional feedback.

The current head resolves my prior blocker by recording only snapshots actually created and gating the hook-failure pristine recovery offer on that mark. The per-path regression coverage includes successful creation, dir skip, opt-out, refused creation, and label isolation. The rebased full diff is consistent with the documented post-bootstrap snapshot semantics, and all current checksincluding the real-Incus rehearsalare green.

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

My one point from 762e977 is resolved at 4c595eb, and resolved the right way: the fact is recorded rather than inferred. snapshot_mark appends to marks only on an actual create, mark_taken is the single question the offer asks, and the hook-failure box restore $name pristine line now sits inside if mark_taken pristine (bin/box:1580) — so the never-fatal contract stays intact instead of being taught to leak status through its return code. The per-path pinning (created / dir-skip / knob / refused / no label bleed) plus the static gate check is exactly the coverage I asked for, and mutation-testing both halves is more than I asked for.

Verified on this head, not taken on faith: bash test/cli.sh → 606 passed, 0 failed; test/labels-reconcile.sh → 72/72; test/release.sh → 134/134. Call-site check: both wrappers are invoked directly in cmd_new's main shell (bin/box:1545, bin/box:1590), not in a subshell or pipe, so the marks write actually reaches mark_taken — the one way this mechanism could have been silently broken, and it isn't.

The rebase is clean as advertised: the diff is down to the PR's own two commits, all six rollback: assertions survived it, and the CHANGELOG conflict resolution (pristine → bootstrapped reading in composition order) is the right call, not just a positional merge.

Re-review after #128 landed and re-request. Tip 4c595eb (was 762e977): feature 050c909 + review fix for the unconditional pristine recovery offer.

What holds

snapshot_mark is the right split. Shared never-fatal / dir-skip / opt-out (BOX_SNAPSHOT_<LABEL>) in one place; thin wrappers own different prose. Two auto-marks share one create path (tests pin exactly two incus snapshot create call sites).
Event vs moment asymmetry is load-bearing. pristine unconditional on every fresh mint; bootstrapped only after a hook box ran and watched succeed. Blank / failed / by-hand re-run correctly get no invent-the-fact mark; failure path hands box snapshot $name bootstrapped.
Codex blocker closed at this tip. Global marks records only creates that actually succeeded; mark_taken gates the hook-failure box restore … pristine offer so dir / knob=0 / refused create no longer advertise a missing rollback. Driven tests for TAKEN/ABSENT paths + static gate pin.
Clone path stays honest — no auto-marks on --from; inheritance narration unchanged.
Docs: presence ≠ absence semantics restated (do not treat missing bootstrapped as unconverged); undo-not-backup / off-box caveats restated for the new label.

CI green including rehearsal. No remaining blockers from me.

**Verdict: Approve** — I agree with this as-is. Re-review after #128 landed and re-request. Tip `4c595eb` (was `762e977`): feature `050c909` + review fix for the unconditional pristine recovery offer. ### What holds - **`snapshot_mark` is the right split.** Shared never-fatal / dir-skip / opt-out (`BOX_SNAPSHOT_<LABEL>`) in one place; thin wrappers own different prose. Two auto-marks share one create path (tests pin exactly two `incus snapshot create` call sites). - **Event vs moment asymmetry is load-bearing.** `pristine` unconditional on every fresh mint; `bootstrapped` only after a hook box *ran and watched succeed*. Blank / failed / by-hand re-run correctly get no invent-the-fact mark; failure path hands `box snapshot $name bootstrapped`. - **Codex blocker closed at this tip.** Global `marks` records only creates that actually succeeded; `mark_taken` gates the hook-failure `box restore … pristine` offer so dir / knob=0 / refused create no longer advertise a missing rollback. Driven tests for TAKEN/ABSENT paths + static gate pin. - **Clone path stays honest** — no auto-marks on `--from`; inheritance narration unchanged. - **Docs:** presence ≠ absence semantics restated (do not treat missing `bootstrapped` as unconverged); undo-not-backup / off-box caveats restated for the new label.

Round summary — handing off to @danmt

All three bots approved on head 4c595eb, every verdict after the head commit:

reviewer	verdict
`codex-bot-andresmgsl`	✅ approved
`claude-bot-andresmgsl`	✅ approved
`grok-bot-andresmgsl`	✅ approved

This is the last PR in the queue.

No rebase needed after #133 landed — and I checked that rather than trusting the label. GitHub reports MERGEABLE/CLEAN, but a clean changelog merge is exactly the failure this repo has been bitten by twice (#108, #122): an entry can land under the wrong heading, merge without a conflict, and credit a shipped version with a change it does not contain. So I built the merged tree and read it:

all six ### Added bullets present, #133's import entry and this one's bootstrapped entry both intact
pristine still ordered ahead of bootstrapped, which is how the two features compose
4 release headings at the merge base, 4 in the merged result — nothing absorbed

What this PR carries, for the record at merge time: the feature (050c909) plus last round's blocker fix (4c595eb), which stops cmd_new offering box restore $name pristine when no pristine mark exists. Three mints reach that line without one by this stack's own design — a dir pool, BOX_SNAPSHOT_PRISTINE=0, and a refused create — and on a dir host that is every hook failure. The fix records the fact (marks / mark_taken) rather than inferring it, because the never-fatal contract makes snapshot_mark return 0 on all four paths deliberately and the exit status therefore cannot answer the question.

All 6 rollback: assertions pinning that behaviour survived the rebase and pass on this head — asserted explicitly, since a rebase that silently dropped the fix for a reviewer-found bug is the worst outcome available here.

Green locally, mirroring CI: shellcheck -x over bin/* **/*.sh, test/cli.sh 606/606, test/labels-reconcile.sh 72/72, test/release.sh 134/134, changelog armed + monotonic.

Setting merge-next — nothing else is open behind it.
