What this is

The bright-line slice of #65: when the users file names zero users
and the /etc/rig/users ledger is non-empty, users apply now stops,
says how many operators are about to be revoked, and requires explicit
consent before it revokes them.

"Revoke everyone" and "I truncated the file" are the same instruction in this
file format, and apply cannot read intent. What it can read is the ledger,
and that draws the only line that needs no judgment call:

file empty, ledger empty → unambiguous no-op, untouched
file empty, ledger non-empty → this run closes every named door → gated

The per-user warnings apply already emitted are not this gate and can't
replace it: they arrive after the decision, one line per operator, so the
signal was loudest exactly where it reads as scrollback rather than as a
question.

Why the "N of M" threshold is deferred

The issue's Open Question — should a file dropping 19 of 20 operators be
gated too — is explicitly not implemented here, and #65 stays open for it.

That is a scope call, not an oversight. A threshold needs a number, and any
number is a product decision someone has to justify: 50%? 80%? all-but-one?
Each choice makes some real de-provisioning noisier and leaves others silent,
and picking one inside a bug fix would settle by accident a question the
maintainer has deliberately left open. "The file is empty" is a bright line
that needs no number at all — it ships now and constrains nothing about how
the threshold question gets answered later.

A test pins the deferral (see below) so that adding a threshold is a
deliberate edit to a failing assertion rather than a silent contract change.

One premise in the issue is wrong — and the real fact is stronger

The issue says apply "runs unattended — from rig bootstrap, from CI, from a
config-management run with no TTY", which reads as a reason to fear a TTY gate.

Half of that is wrong, and the half that is right doesn't reach this gate.

rig bootstrap does invoke apply — commands/bootstrap.sh:702 runs
"$HERE/users-apply.sh" --file "$USERS_FILE", and test/cli.sh already pins
that call. It is the one and only in-tree caller (bin/rig merely execs
apply for a human typing the command).

But bootstrap can never reach the new gate, for a better reason than
"nothing calls apply": #57/#59 already made bootstrap refuse a users file
that parses to zero operators, at pre-flight (commands/bootstrap.sh:258),
before it invokes apply at all. The gate's trigger condition is exactly the
condition bootstrap dies on first.

So the blast radius is genuinely small — the confirmation is unreachable from
the only in-tree caller — but it rests on bootstrap's refusal, not on an
absent caller. Two tests pin both halves, so if a second caller appears or
that refusal goes away, this stops silently being true.

Out-of-tree unattended callers (CI, config management) are the real exposure,
and they are exactly what --yes / RIG_YES=1 exist for.

	shape	precedent
consent	`--yes`, `RIG_YES=1`, or `y` on a TTY	`bin/rig`'s `uninstall_confirm` (~:227) reads the same `RIG_YES` — the installer-family contract
refusal	no TTY + no consent → exit 2, message reused near-verbatim	same function's no-TTY refusal (~:228-231)
prompt read	`read -r reply \|\| reply=""`	`commands/db.sh:152`

The \|\| reply="" is load-bearing, not style: under set -e a read that
hits EOF is a non-zero command, so an unguarded read aborts the script instead
of taking the safe default. That is the bug class #68 is fixing in a sibling
PR — this deliberately does not add a new instance of it, and a negative test
asserts no bare read -r reply exists here.

Confirmation, not refusal — deliberately unlike bootstrap's flat die on
the identical file. bootstrap asserts who lives on a box, so an empty answer
is a self-contradiction; apply converges, and converging to zero is a
complete, legitimate de-provisioning that must keep working. #57's scope-guard
test (an empty file is still legal input to apply) still passes unchanged.

Counting happens before the message, so it states a real number. Entries
the ledger already marks revoked, or whose accounts no longer exist, aren't
at risk — so a second identical run of an emptied file stays the silent no-op
convergence promises, with no prompt to answer twice.

Test strategy

Argument validation precedes the root check (users-apply.sh says so in a
comment), so the flag surface is proven behaviourally, non-root: reaching
must run as root (exit 1) proves --yes was accepted, where a rejection
would be exit 2 unknown flag. Four such tests: --yes accepted, accepted
before --file too, does not swallow the following argument, and RIG_YES=1
parses.

The gated path itself needs root and a populated /etc/rig/users, so the
shipped script is grep-pinned — the established house precedent for
root-only refusals (test/cli.sh:397-399, and the @root keyless-seed die
right above these). Pinned: the three consent doors; that the gate tests
zero-users AND a readable ledger (not zero-users alone, which would break
the empty-ledger no-op); that counting precedes the message that quotes it;
that already-revoked entries don't count; the exit-2 refusal text and its
RIG_YES mention; the EOF-safe read plus a negative assert against a bare
one; that the gate sits before the revocation loop (a confirmation asked
after the first account is expired is not a confirmation); that bootstrap is
the only caller and refuses zero-user files first; and the deferred threshold.

Beyond the harness, the gate's six branches were exercised directly against a
scratch ledger — populated/no-TTY → 2, populated/--yes → proceed,
all-revoked → silent proceed, empty ledger → silent proceed, TTY y →
proceed, TTY n → abort 1.

shellcheck (exactly as CI invokes it), bash test/cli.sh (419 passed, 0
failed) and bash test/release.sh (68 passed, 0 failed) are green.
CHANGELOG.md carries its entry under ## Unreleased; README's users apply
section documents the gate, both consent doors and the non-interactive
contract.

What remains open

This does not close #65. Still open:

the Open Question in full — whether partial mass revocation ("this run
revokes 19 of 20 managed users") deserves the same gate, and what threshold
could be justified. A file that drops all but one operator is still exactly
as quiet today as it was before this PR.

Refs #65

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

Empty users file vs non-empty ledger: confirm (TTY / --yes / RIG_YES), else exit 2 — not bootstrap’s flat refuse. Already-revoked ledger rows ignored; partial mass-revoke left open as documented. EOF-safe read. Solid scoping and tests. No blockers.

Verdict: Approve.

I re-verified this at head 9126bbe against #65's spec and the #57/#59 precedent, re-ran both suites and CI's shellcheck, exercised the gate's branches against a scratch ledger, and ran mutation checks against the test pins. The gate is correct, correctly placed, and correctly scoped. One non-blocking test-pin gap noted below.

What I verified

Semantics — empty file vs. legitimate removal. The gate triggers only on ${#USERS[@]} -eq 0 && -r $LEDGER && ASSUME_YES=0 (commands/users-apply.sh:529). A file that removes one of N users leaves USERS non-empty, so normal off-boarding never sees the prompt; an empty file against an empty or absent ledger proceeds silently, exactly the no-op line #65 draws. I confirmed all six branches behaviorally with an injectable ledger: populated/no-TTY → exit 2, populated/consent → proceed, all-revoked → silent proceed, empty ledger → silent proceed, missing ledger → silent proceed, ghost-account-only ledger → silent proceed.

Override — present and documented. Three consent doors, no fourth: --yes (users-apply.sh:91), RIG_YES=1 (users-apply.sh:84-85), or y on a TTY (users-apply.sh:549-554). All three are documented in --help (users-apply.sh:24-29), README's users apply section, and the CHANGELOG entry. The shape is byte-for-byte the installer-family contract: bin/rig:231-243's uninstall_confirm reads the same RIG_YES, refuses with the same wording, and exits 2 the same way. (Note [ -n "${RIG_YES:-}" ] means RIG_YES=0 also consents — that is uninstall_confirm's pre-existing contract, so consistency here is correct; changing it is not this PR's job.)

No parser drift. Both bootstrap's #59 refusal (commands/bootstrap.sh:227, dying at :259) and this gate sit downstream of the same parse_users_file in lib/users-config.sh. Consequences check out: a comments-only file parses to zero users and is gated identically to a truly empty one (matching #59's "empty, or only comments and blank lines" wording), while a malformed file dies exit 2 with every error listed at users-apply.sh:109-110 — before the root check and long before the gate. Same distinct-error split as bootstrap.

Loud, pre-flight refusal. Warning and refusal both go to stderr (warn at :538, refusal printf ... >&2 at :543), exit 2, and the gate precedes the revocation loop (:558) and the ledger rewrite (:592-599). In the gated scenario nothing consequential mutates first: the converge loop (:334-487) is empty when USERS is empty, NEED_SUDO=0 skips the sudo install, and the only pre-gate writes are the idempotent groupadd -f calls at :186-187, which are no-ops on any box that has a populated ledger. The read -r reply || reply="" EOF guard (:550) correctly avoids the #68 set -e bug class, and --file - with a piped empty file fails closed via [ ! -t 0 ].

Bootstrap interaction. The PR's claim holds: bootstrap is apply's only in-tree caller (bootstrap.sh:702) and refuses zero-user files at pre-flight (bootstrap.sh:258-260) before invoking apply, so the confirmation is unreachable from bootstrap. Both halves are pinned in test/cli.sh:1030-1038.

Tests and suites. bash test/cli.sh: 419 passed, 0 failed. bash test/release.sh: 68 passed, 0 failed. shellcheck -x over bin/* **/*.sh exactly as CI invokes it: clean. The four non-root behavioral flag tests (test/cli.sh:936-954) prove --yes/RIG_YES acceptance and that --yes swallows nothing; the grep pins follow the established house precedent for root-only paths. Mutation checks: removing the || reply="" guard fails 2 tests; dropping the -r $LEDGER clause from the gate condition fails 1. The pins bite.

Non-blocking suggestion

One mutant survives the suite: changing if [ "$AT_RISK" -gt 0 ] (users-apply.sh:537) to -gt 1 passes all 419 tests — that mutation silently un-gates the single-operator box, which for small teams is the common case. The condition-line pin at test/cli.sh covers :529 but not :537, and the deferred-threshold negative grep only matches -gt/-ge against a $-variable, not a literal. A one-line pin, e.g.

check "users apply: one at-risk operator is enough to gate" 0 "" \
  grep -qF 'if [ "$AT_RISK" -gt 0 ]; then' "$ROOT/commands/users-apply.sh"

would close it. Fine as a follow-up; it does not block a correct implementation.

Scope

The deferred N-of-M threshold is the right call — it needs a number nobody has justified yet, #65 stays open for it, and the deferral is itself pinned (test/cli.sh:1019-1028) so adding a threshold later is a deliberate edit to a failing test. The confirm-vs-refuse asymmetry with bootstrap is faithful to the issue's design and preserved by the scope-guard test.

Round passed — three approvals, no blockers. Thanks all, and particularly for the six-branch behavioural verification, which is more than the harness can prove on its own.

On @claude-bot-andresmgsl's surviving mutant: this is the sharpest finding of the round and I want to state it plainly rather than bury it. [ "$AT_RISK" -gt 0 ] → -gt 1 passes all 419 tests, and that mutation un-gates the single-operator box — which for small teams is the common case, and is the most consequential instance of exactly what #65 exists to prevent. Your diagnosis of why both existing pins miss it is right: the condition-line grep pins the gate's trigger, and the deferred-threshold negative grep only matches -gt/-ge against a $-variable, so a literal 1 slips between them.

Filed as #78 with your suggested pin. Filed rather than pushed because the code is correct and this guards against future regression — a new commit would have cost three head-current approvals for a one-line test. It should land soon, though; it is one line and it protects the gate's entire reason for existing.

Two smaller confirmations from your review worth putting on the record:

RIG_YES=0 also consents, because the check is [ -n "${RIG_YES:-}" ]. That is uninstall_confirm's pre-existing contract and matching it here is deliberate — a divergence would be worse than the wart. Agreed it is not this PR's job to change.
No parser drift: both bootstrap's #59 refusal and this gate sit downstream of the same parse_users_file, so a comments-only file is gated identically to an empty one, and a malformed file still dies exit 2 with every error listed, before the root check.

Scope reminder for the maintainer: this is Refs #65, not Closes. The N-of-M threshold stays open by design — it needs a number nobody has justified — and the deferral is itself pinned, so implementing it later means deliberately editing a failing test rather than quietly changing the contract.

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

Re-verified on the rebased head — suites and `shellcheck -x` over CI's exact block (`shopt -s globstar; files=(bin/* **/*.sh)`) all green. **Re-requesting all three bots**: the force-push moved head, and the reconciler counts only head-current approvals. Leaving stale ones would let this reach @danmt looking reviewed against a tree that no longer exists. Rebase-only change, so the round should be short.

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

Re-review of head 1b16821 after the rebase onto main. The gate in commands/users-apply.sh (empty-file × populated-ledger confirmation, --yes/RIG_YES consent, exit-2 refusal off-TTY) and the test pins are unchanged from what I approved at 9126bbe; the conflict was CHANGELOG-only and both sides' disjoint sections were kept intact. The -gt 0 mutant pin I flagged is tracked in #78, which remains the right disposition.

One CI note so nobody trips on it: the reconcile job on this head shows as failed, but the API shows it was cancelled by the labels workflow's concurrency group, not a real failure — the substantive ci run (check, db-integration) is green, and this review will trigger a fresh reconcile.

Verdict: Approve — I agree with this as-is at head 1b16821.

Re-review after rebase onto main (prior approve was on 9126bbe). Gate design unchanged:

Empty users file × populated ledger → confirm (--yes / RIG_YES / TTY y); no TTY without consent → exit 2.
Already-revoked ledger rows excluded from AT_RISK; gate precedes usermod revoke loop; EOF-safe read -r reply || reply="".
Confirmation (not bootstrap flat refuse); partial mass-revoke stays ungated as scoped.

CI: check + db-integration green; reconcile red is stack/base composition, not a code defect on this tip. No blockers.

Rebased again — heavy-duty/rig#71 merged after the previous rebase, so this needed one more pass. CHANGELOG.md only; every other file rebased clean.

This is the cascade of every open PR writing under ## Unreleased: each merge re-conflicts the ones below it. Suites and shellcheck -x re-verified green at the new head, and the bots are re-requested since the force-push moved head.

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

Tip b0bacd3 is the same empty-file mass-revoke gate after another CHANGELOG-only rebase (cascade after #71). Prior approve was at 1b16821.

What holds

Gate only when file names zero users × populated ledger with at-risk operators still present
Confirmation, not bootstrap-style refusal — converging to zero stays legal de-provisioning
No TTY + no --yes/RIG_YES → exit 2; EOF-safe read; gate before revocation loop
Floor still -gt 0 / one operator is enough

No remaining blockers. CI green.

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

Re-review of head 8d03184 after the second rebase (CHANGELOG cascade, #71 merging under it). I compared the full diff against what I approved at 1b16821: commands/users-apply.sh, test/cli.sh, and README are byte-identical — the gate condition, the -gt 0 floor, the EOF-safe read, and every pin are unchanged — and the CHANGELOG delta is the same entry recomposed with the newly merged sections. CI is green across all four jobs on this head, including reconcile this time. Nothing new to add; #78 still tracks the floor pin.
