bin/gstack-post posts a PR/MR or issue comment, a review-comment reply, a
PR title or body, a new PR/MR or a new issue from agent-written files. Every
value reaches gh/glab as its own argv element in --flag=<value> form or on
stdin, never through a shell string, and a target is a number or a URL of
this repository on the same host.
The helper owns the redaction scan: it reads each file once, scans those
exact bytes (visibility from config, then gh/glab; the pusher's own email
suppressed) and sends the same bytes. HIGH is refused with exit 1 and no
confirmation can post it. MEDIUM exits 2 with RULE:/LINE:/PART: lines and a
TOKEN: digest of the bytes, destination, operation and findings; only
--confirm <token> for those exact bytes posts, so any edit needs a new
confirmation. gh/glab failures exit 3, usage errors 64. It also carries the
projectCards REST fallback and the title read-back that /ship did by hand.
The logic lives in lib/gstack-post.ts behind an injectable runner, so its
tests run in the Windows free lane; the stub-gh executable test is POSIX.
