…eck` had just refused #502 C3. Reproduced end to end in a throwaway repo before anything was changed. ⛔ THE DEFECT. With all 8 roles provisioned and every one of them NODOCTRINE — a tree that exists, sits in the conventional location, and whose HEAD carries no `prompts/`: check -> exit 1 "⛔ 8 role(s) have a tree that does NOT carry the doctrine" "⇒ Re-create from a ref that carries them: … create <ref>" create -> exit 0 "nothing to create — no role is without a tree" ⇒ THE TOOL TOLD THE OPERATOR TO RUN A COMMAND THAT REFUSES, and refuses with exit 0 — reporting success for the state it had just called blocking. `create <ref>`, spelled exactly as the message spells it, behaves identically: the guard is `n_missing -eq 0`, and a NODOCTRINE tree EXISTS, so nothing is missing. ★ THE FIX IS NOT TO AUTO-REMEDIATE. This file's own stance, six lines into `where()`, is that a suspect tree is "reported for a human to judge, and never auto-remediated" — and `git worktree remove` can destroy uncommitted work. So `create` now REFUSES loudly and prints the two commands that actually do it, per role, rather than silently doing nothing or silently doing something. PROVEN TWO-SIDED, in a sandbox repo built to the exact state: ⛔ 8 trees, all NODOCTRINE, 0 MISSING before exit 0 "nothing to create — no role is without a tree" after exit 1 names all 8 and prints `git worktree remove <path> && … create <ref>` ✅ the same 8 trees, doctrine PRESENT after exit 0 "nothing to create — no role is without a tree" ⇒ The branch fires on the state it is for and does not over-fire on the healthy one. Without that second pole a guard that refused everything would have passed the first. ⚠ The sandbox needed building twice. My first attempt had ONE tree present, so `n_missing` was 7 and `create` cheerfully built the other seven — the defect needs `n_missing == 0` to be visible at all, and a partial fixture hid it.

In `@scripts/fleet-worktree.sh`:
- Line 196: Update the state-handling logic around the n_missing and
n_nodoctrine counters so mixed non-zero states repair or report both missing and
NODOCTRINE roles instead of treating the existing NODOCTRINE roles as complete.
Preserve valid-ref success behavior while emitting the required repair commands,
and add a regression test covering mixed-state create behavior.
- Around line 203-204: Update the generated repair-command printf in the
worktree script to format both the WT_DIR/r path value and the script path from
$0 with Bash %q, so copied commands remain safely shell-escaped while preserving
the existing command structure.

…pair line was unquoted
Both review findings adopted. The first is the sharper, and it is the state my own
reproduction had stumbled into and walked past.
1. ⛔ MIXED `MISSING` + `NODOCTRINE` EXITED 0 WITH BROKEN TREES LEFT BEHIND. My guard was
`n_missing -eq 0 && n_nodoctrine -gt 0`, so it only fired when nothing was absent.
With both counters non-zero, `create` provisioned the absent roles and said nothing
about the existing doctrine-less ones. Isolated in a repo whose OLD commit lacks
prompts/ and whose main carries them — 3 NODOCTRINE trees, 5 MISSING, valid ref:
BEFORE rc=0 created 5 · nodoctrine reports 0 · 3 broken trees left, unmentioned
AFTER rc=1 created 5 · names all 3 and prints the per-role repair
★ That mixed state is exactly the fixture my first reproduction built by accident —
one tree present, seven missing — and it is why the original defect was invisible on
the first attempt. I recorded that as "a partial fixture hid it" and did not notice
the same partial state was also a hole in the fix.
⚠ MY FIRST BEFORE/AFTER WAS CONFOUNDED and I nearly published it. The fixture built
its new trees from a ref with no prompts/, so the create loop set rc=1 for an
unrelated reason and BEFORE read 1, not 0 — the finding says "returns success WHEN
THE NEW TREES USE A VALID REF", and mine did not. Rebuilt with a valid ref, the
isolation is exact.
⇒ The report is hoisted into `report_nodoctrine()` and called from BOTH entry points,
because the state had two and the first version guarded one.
2. ⚠ THE PRINTED REPAIR COMMANDS WERE UNQUOTED. The operator COPIES those lines, and a
worktree path containing a space — `C:\Program Files\…` is a normal location — yields
a command that silently removes the wrong thing. `%q` now, and `--` before the path.
git worktree remove -- /srv/Program\ Files/wt/architect
★ Same root as #502 C2, one surface along: there a space broke a PARSER, here it
breaks a command a human is about to run. C2 was found by an installer, this by
review, and neither sweep would have found the other.
THREE STATES, all exercised:
⛔ 8 NODOCTRINE · 0 MISSING -> rc 1, report
⛔ 3 NODOCTRINE · 5 MISSING -> rc 1, report, 5 provisioned (was rc 0, silent)
✅ doctrine present -> rc 0, "nothing to create", no report
Without the third, a branch that reported unconditionally would pass the first two.
