- issue-assign + milestone-create: set -o pipefail; the remove-assignee
lookup pipeline now fails loud on provider failure instead of reading
an empty result as a silent no-assignees skip (codex blocker). A
successful lookup with zero assignees still skips the edit.
- test-issue-assign-usage-contract: 6b arm proves provider-exit
normalization end to end (gh stub exiting 2 on issue edit -> wrapper
exit 1 with the normalized stderr message; codex should-fix).
- Battery: 23/23 suites green.
- Value guards now reject option-like values: --anything always, and
single-dash flag shapes (-h, -i). Previously -b --help consumed
--help as the body and performed the write (codex example:
issue-close -i --help proceeding to 'Closed GitHub issue #--help').
Multi-char dash-leading text (-start of a list) stays a legal value.
- Every remaining direct provider exec (gh/tea/CMD arrays across
issue-create/edit/assign/list/view, milestone-*, pr-create/edit,
pr-close, issue-close/reopen) wrapped with rc capture and normalized
to exit 1 with a stderr message — provider exit 2 no longer collides
with the reserved usage-error status.
- All 16 usage-contract suites gained option-like and short-flag arms
(16/16 green). Existing suites re-verified; test-pr-edit and
test-issue-create-interactive-auth fail identically with these
changes stashed (environment-coupled, not regressions; documented).
