Subject: [PATCH 1/2] hooks: the three remaining guards name the environment
 their hatch variable must be set in, never a command prefix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

guard-main-checkout-bash.sh, guard-shared-stash.sh and guard-tree-enum.sh each
ended their refusal with `re-run with OS_ALLOW_*=1`. Followed literally, a
`VAR=1 <cmd>` prefix sets the variable for that command only; the hook reads
`${OS_ALLOW_*:-}` from its OWN environment, where nothing set it, so it blocks
again while echoing the prefix it saw. An instruction that cannot work where it
is printed is an invitation to route around the guard, and after the
guard-main-checkout.sh half landed the two sibling guards for the same hatch
were giving an operator opposite instructions — the Bash guard, reached when an
agent writes through a shell, being the one still advertising the dead remedy.

Each hatch sentence is replaced with the objectstack twin's wording, ported
byte-for-byte so the executable lines of the guards stay identical across the
two repositories. Reversing the pin's declared divergences out of all six
ported files reproduces objectstack@7c2c5aed's blobs exactly.

Each self-test gains the pair that keeps this from being re-lost: `lacks
're-run with'` (the dead remedy is gone) and `says 'hook itself runs in'` (the
sentence names the environment the hook really reads), in the idiom
guard-main-checkout.selftest.sh already uses, together with the stderr_of /
says / lacks helpers those two assertions need. The bash matrix also takes
upstream's two prefix-reproduction rows, which assert that the prefix spelled
exactly as the old message told the reader to spell it still blocks.

guard-shared-stash.sh's self-test case count is re-derived by the recipe the
header itself gives (46 `expect ` lines + 2 inline specials + the 2 new message
assertions = 50, equal to the run's own tail), and the pin entry that declares
that count as a divergence from upstream moves with it.

Self-tests, in this worktree: guard-main-checkout-bash 130 passed 0 failed,
guard-main-checkout 120/0 (untouched), guard-shared-stash 50/0, guard-tree-enum
38/0. `git grep -n 're-run with' -- .claude/hooks` now hits 5 lines, every one
of them a self-test assertion.

check:upstream-port-parity is RED on six stale pin entries and needs a re-sync
at merge: the pinned refs predate this wording upstream, and the re-sync write
path is reserved by name for the human merging governed surface.

Subject: [PATCH 2/2] hooks: re-sync the six pinned guard entries to
 objectstack 7c2c5aed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

check-upstream-port-parity red-flagged the previous commit: these guards are
PINNED ports of objectstack's files, so the deliberate act for wording that
moved upstream is a re-sync, not a hand edit. Ran the gate's own procedure, once
per ported path:

  node scripts/check-upstream-port-parity.mjs --resync UPSTREAM_FILE \
    --path .claude/hooks/FILE --ref 7c2c5aedd94d7b0d94c91432bc607862e9c83c6c \
    --rewrite-governed-file

for guard-main-checkout-bash.sh, guard-shared-stash.sh, guard-tree-enum.sh and
their three self-tests, with UPSTREAM_FILE taken from
`git show origin/main:.claude/hooks/FILE` in the objectstack checkout. The
governed-surface flag is required because .claude/** is governed here; the gate
names it and printed the rewrite for each of the six. No pinned digest was
edited by hand.

What the re-sync changed: nothing in any hook. All six files came back
byte-identical to the previous commit's hand-ported text, because objectstack's
movement since each pinned ref is exactly this card's change and nothing else
(+4/-1 per hook, +47/+39/+41 per self-test). The only diff this commit carries
is scripts/upstream-port-pin.json: six `ref` values to 7c2c5aed and six
`upstreamSha256` values, twelve lines. The five other pinned entries keep their
own refs, as the gate guarantees. Every declared divergence was re-applied and
survives — guard-shared-stash.sh still carries its own self-test case count with
the re-derivation recipe (46 `expect ` lines + 2 inline specials + the 2 new
message assertions = 50, equal to the run's tail), and the objectui card
references and worktree example names are intact.

Verified after the re-sync: check-upstream-port-parity exits 0 with ✓ for all 11
entries at 5 distinct refs; its --self-test 58 cases pass; the three hatch
sentences read the upstream form; `git grep -n 're-run with' -- .claude/hooks`
hits 5 lines, all self-test assertions; hook self-tests 130 / 120 / 50 / 38
passed, 0 failed. Also green: check-lint-coverage, check-entry-guard,
check-control-bytes, check-bash32-floor, check-changeset-presence (no changeset
owed), check-governed-queue-guard --self-test.
