/ship: Step 18 writes the title into an agent-written file. An existing PR's title is piped from gh/glab through gstack-pr-title-rewrite.sh --stdin (new), so neither the agent nor a shell string carries it; a new title is written with the file tool and its version prefix checked in the file. Step 19 composes the body as before and publishes with gstack-post pr-create, or pr-body then pr-title, which scan the exact bytes they send. The separate title and body scans, the hand-rolled REST fallback and the title self-check are gone (the helper does all three). Title preparation moved into the pr-body section, so the skeleton shrinks. /spec files its issue with gstack-post issue-create and drops the pre-issue re-scan; Greptile replies use gstack-post reply and pr-comment. scripts/resolvers/redact-doc.ts loses its PR and issue sinks, and a test keeps any template from rendering one again. Tests that pinned the old scan-then-gh wiring now pin the gstack-post wiring; the publication tests run the real compose and publish blocks against a stub gh with the real helper (HIGH in title or body refused, MEDIUM token flow).

# Rewrite a PR/MR title to start with v<NEW_VERSION>.
|
|
#
|
|
# Usage: bin/gstack-pr-title-rewrite.sh <NEW_VERSION> <CURRENT_TITLE>
|
|
# gh pr view N --json title -q .title | bin/gstack-pr-title-rewrite.sh <NEW_VERSION> --stdin
|
|
# Output: corrected title on stdout. --stdin reads the title from standard
|
|
# input, so /ship pipes the platform's title through without the agent or a
|
|
# shell string ever carrying it.
|
|
#
|
|
# Rule: PR titles MUST start with v<NEW_VERSION>. Three cases:
|
|
# 1. Already starts with "v<NEW_VERSION>" -> no change.
|
|
# 2. Starts with a different "v<digits and dots>" prefix -> replace prefix.
|
|
# 3. No version prefix -> prepend "v<NEW_VERSION> ".
|
|
#
|
|
# Each version prefix may be followed by a space (then a description) OR sit at
|
|
# the end of the title as a bare version with no description (e.g. "v1.2.3", the
|
|
# format ship/CHANGELOG uses for version-only bumps). Both forms must be handled
|
|
# in cases 1 and 2, otherwise a bare version falls through to case 3 and gets a
|
|
# second prefix prepended, e.g. "v1.2.3" -> "v1.2.3.4 v1.2.3". The CI workflow
|
|
# .github/workflows/pr-title-sync.yml feeds real PR titles through this and then
|
|
# `gh pr edit`s the result, so the duplicated title would be written back.
|
|
#
|
|
# The version-prefix regex matches two or more dot-separated digit segments
|
|
# (covers v1.2, v1.2.3, v1.2.3.4) so the rule is portable across repos that
|
|
# use 3-part or 4-part versions, but does NOT strip plain words like
|
|
# "version 5".
