`gh api` prints a 5xx response body to stdout AND exits non-zero, and
GitHub's 5xx body is a JSON object. Inside the per-issue subshell that
payload passed `has("pull_request") | not`, emptied `.labels[]`, and
`queue_decision` — correct on the input it was handed — wrote
`needs-triage` onto a healthy epic. The run then logged `reconciled.`
and exited 0 (crew#329, #247).
errexit could not have caught it: a command whose status is tested by
`||` runs with errexit suppressed, and the suppression extends through
the whole subshell body, so the `|| log` handler is what disables the
errexit that would have aborted at the failed read. Removing the handler
revives errexit and loses #91's resilience, and an inline `set -e` does
not re-arm it. Explicit per-read checks are the mechanism.
Every read inside that subshell is now checked — the issue read on its
status AND on its payload shape (an HTTP 200 whose body is `null` exits
0 and empties the label set just the same), both reads in
`last_issue_activity`, and the comments read in
`issue_comment_has_marker`. On failure the issue is left exactly as it
is, the reason rides its own `#$n:` line, and the subshell exits with a
distinguished status the sweep counts, so a deliberate skip is not
reported as a crash and a genuine crash is still named byte-identically.
`read_failure_reason` moves to lib/read.sh beside a new `guarded_read`,
sourced by both reconcilers: labels-reconcile's copy was the only one,
and the issue surface needs the identical rule.

issue_probe's merged-PR argument becomes a spec list — `PR` or `PR@<iso>`
— so a probe can state merge order; the bare form keeps every existing call
site literal.
The direct-drive cases cover crew#176's shape (the lower number merged
later), agreeing orders, interleaved issues, the mergedAt tie broken by
highest PR number under both input orders, and the empty answer. The
end-to-end probe is crew#321's: a marker already standing for the
later-merged, lower-numbered PR must suppress the transition, which
selecting by number could never do.
Two static pins keep the request count honest — the sweep issues exactly two
GraphQL queries, with mergedAt selected on the merged-PR node it already
fetched.
Refs #242
post_merge_pr_for_issue answered "which merged Refs PR is this issue's
deliverable?" with sort -n | tail -n1. Merge order is not number order:
crew#176's two Refs PRs merged #184 at 19:05:16Z and #182 at 19:05:18Z.
MERGED_REF_PR_RECORDS gains mergedAt as a third column — a field on the
merged-PR node set already fetched, so no additional GraphQL request — and
the selection sorts on it, breaking ties by highest PR number so the answer
never depends on input order.
Refs #242
Binding to the first marker occurrence dropped every later sentence of a
repeated declaration and let earlier prose hijack the parse — the false
ready promotion on rig#154. Each occurrence now contributes its own
clause, terminated at its own first ./; (unterminated -> end of input),
and the union feeds the unchanged classification and decision table.
Closes#184

reconcile_opened_issue's two early exits were bare returns, which carry
the failed guard's status into the executed script's set -e — every
triage-authored mint killed the labels run before one issue was
reconciled (#91, 4/4 observed). The stand-downs now say return 0; a
genuine failure on the arrival path still aborts loudly.
The suite sources the script and takes the set -u-only branch, so it
was blind to this by construction. The new arrival section executes the
script as a subprocess behind a fixture-serving gh stub (the house
pattern from test/release-chain.test.sh) and covers all three arrival
outcomes plus the preserved loud-failure path; it fails against
bb37c15 with the production signature — exit 1, empty output.

Issue side: the claim-reclaim clock stops under a pending ruling (the
decision still sees an unassigned claim), an already-applied stale heals
off, and reconcile_ruling runs for any flagged issue on any queue state.
PR side: reconcile_ruling rides the (#51) stale section's real-activity
computation. test/ruling.test.sh pins the window boundaries, newest-event
anchoring, per-event marker scoping, the markerless nudge reset, the
unreadable-timeline rule, and that no scenario writes a label.
