Slice B (items 1, 11). Draft; no e2e label (fast suite covers it).

What

• Release notes move from ## [Unreleased] to changelog.d/<topic>.md fragments: the CHANGELOG's own ### <Section> headings with - bullets (allowlist inventoried from CHANGELOG.md: Operator action required, Added, Changed, Removed, Fixed, Security). ## [Unreleased] stays as an empty section with a pointer comment.
• docker/check-changelog.ts: keeps both existing forms, and now requires every fragment to parse (known sections only, >=1 bullet), and fails any [Unreleased] entries with a message pointing at changelog.d/.
• docker/changelog-release.ts <version> [date] [--dry-run]: assembles fragments into ## [<version>] - <date> right after Unreleased (canonical order, operator action first and always present as - None. when absent, bullets verbatim in file-name order), deletes the fragments. Header starts with ## [<version>] so the images.yml prerelease-notes awk matches unchanged.
• docker/pr-ready.ts: area detection vs git merge-base origin/main HEAD (runner/ui/cli/docs/workflows), gates per area (bun run check always; cargo fmt/clippy/test; tsc/test/build; always check-changelog, check-versions, check-tests when present), git fetch + git merge-tree --write-tree mergeability check (conflict message notes conflicting PRs get no CI), fragment-missing warning, sensitive-paths note (no list file yet), --skip-build, summary table. No pipes; exit codes read straight from spawned processes.
• Tests beside the scripts (bun test docker/, wired into check.yml): canonical order, operator default, verbatim multi-line bullets, unknown-heading rejection, Unreleased-edit rejection; area detection and glob matching (incl. ! negation, dotfiles). Each failed before the implementation.
• Docs: AGENTS.md release step, Agent-behavior fragment rule, Build-and-run pr-ready line. No other repo docs told contributors to edit [Unreleased] (grepped).
• No toolchain pin found (CI uses dtolnay/rust-toolchain@stable, no rust-version in Cargo.toml): pr-ready documents this and uses ~/.cargo/bin/cargo.

Cutover proof (no line lost)

Ran with only the cutover fragment present:

$ bun docker/changelog-release.ts 0.1.0-alpha.9 2026-10-22 --dry-run > /tmp/assembled.md
$ git show HEAD:CHANGELOG.md | awk '/^## \[Unreleased\]/{f=1;next} f&&/^## \[/{exit} f' | grep -v '^$' > /tmp/old-body.txt
$ awk '/^## \[0.1.0-alpha.9\]/{f=1;next} f&&/^## \[/{exit} f' /tmp/assembled.md | grep -v '^$' > /tmp/new-body.txt
$ diff /tmp/old-body.txt /tmp/new-body.txt && echo CUTOVER-DIFF-EMPTY
CUTOVER-DIFF-EMPTY

(blank-line-insensitive; separators are not preserved across regrouping, every content line survives; 16 bullets each side; awk extraction verified on the assembled section)

pr-ready on this branch

pr-ready: areas [docs, workflows]
bun run check    PASS  ok
check-changelog  PASS  ok
check-versions   PASS  ok
check-tests      SKIP  docker/check-tests.ts not present yet (slice C)
merge-tree       PASS  clean
sensitive  INFO  no sensitive list yet (.github/security-paths.yml missing)

Verification

• bun run check clean; bun test docker/ 26/26; UI tsc --noEmit clean, UI tests 589/589, bun run build clean; cargo fmt/clippy clean, cargo test --locked 582/582.
• New check rejects the pre-cutover tree (verified before cutover: fails on [Unreleased] has entries).

Notes for the parent

• check.yml gains one step (bun test docker/); slice C's check-tests.ts joins it automatically when it lands. Overlap with C is that step only.
• images.yml untouched (awk verified working).

Parent: rebased onto 7c0986e, which brings in #85 and #87. I redid the cutover against current main: changelog.d/alpha9-before-fragments.md now holds main's whole [Unreleased] body, with 19 bullets (#85's two and #87's one included).

Dry-run proof: I assembled only that fragment into a temp copy with changelog-release.ts and diffed the result against main's [Unreleased], blank-line-insensitive. The output was CUTOVER-DIFF-EMPTY. bun run check, bun test docker/ (26 pass), check-changelog and check-versions all pass.

The parent reviewed and smoke-tested the release assembly earlier, too. Once CI is green, this is the first PR through the new merge queue.
