- Option-like value = any token starting with '-' followed by an
alphanumeric (-h, -ab, --help); multi-character short clusters were
still accepted (codex blocker). Bare '-' is reserved (future stdin).
- usage_error now prints the usage text to stderr as well (codex
should-fix): usage output belonged to stdout only on the help path.
- 16/16 usage-contract 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).
Same contract as issue-comment (PR #1462): -b/--body canonical comment
flag with -c/--comment alias; usage errors stderr + exit 2 (unknown
option, missing -i, value-less flags); provider failures normalized to
exit 1 on the GitHub path (gh's own usage errors exit 2 and would
collide with the reserved status).
New suite test-issue-close-usage-contract.sh, enrolled in
framework-shell CI (enumeration guard OK, population 74). Probe
assertions split: parser arms must contact zero providers; sandbox arms
may issue detection reads only (tea login list), never gh/curl.
Existing fail-closed suite still green. Mirrored to the brain tree.
