scaffold-e2e's docker leg only exercises the --skip-install shape, so the pinned Dockerfile users actually get has no e2e coverage

Observation found while implementing #9017 (PR #9115). Not a defect in that PR — recording it because the gap is invisible from either file alone.

What is covered, and what is not

.github/workflows/scaffold-e2e.yml scaffolds with --skip-install:

node "$GITHUB_WORKSPACE/packages/create-objectstack/bin/create-objectstack.js" e2e-app --skip-install --skip-skills

and the workflow then runs npm install itself, so the generated project is installed but the scaffolder's own post-install step never runs.

PR #9115 makes the scaffolder pin the Dockerfile's runtime image tag to the @objectstack/cli version the project resolved — and that pin happens after the scaffolder's install, which --skip-install suppresses. So:

the shape the e2e builds and boots is the unpinned one (FROM ghcr.io/objectstack-ai/objectstack:latest);
the shape a real npx create-objectstack user ships is the pinned one;
the docker leg's own comment says it "exercises the exact Docker path a real npm create objectstack user ships", which is now true only of the --skip-install variant.

The pinned shape is covered by packages/create-objectstack/src/runtime-image.test.ts, which asserts on scaffolded output, so this is a missing end-to-end leg rather than an untested behaviour.

Why it is not simply fixed in that PR

Letting the e2e scaffold without --skip-install is not a one-line swap: the workflow's install step carries the unpublished-version fallback (it rewrites the app's @objectstack/* ranges to latest when the repo version is not yet on the registry, then re-stamps engines.protocol), and moving the install into the scaffolder would move that fallback too. That is a deliberate design worth its own card rather than a rider.

Possible shapes

Scaffold a second, small project without --skip-install purely to assert the emitted Dockerfile is pinned — cheap, no docker build needed.
Or teach the existing leg to run the scaffolder's install path, and relocate the unpublished-version fallback accordingly.

Neither is obviously right; the first is much cheaper and covers the actual regression risk (the pin silently not happening).

Related: #9017, PR #9115.

Finding first-touch grading: promoted → pm:queue + domain:devx (fix lands in .github/workflows/scaffold-e2e.yml), type Task.

Premise verified this round: #9017 is closed and PR #9115's pin is on origin/main (f2f09e4), so the coverage gap is live — the e2e's docker leg builds the unpinned shape while every real npx create-objectstack user ships the pinned one, and the leg's own comment now overclaims.

Route suggestion: the card's first shape — scaffold a second small project without --skip-install purely to assert the emitted Dockerfile is pinned (no docker build), leaving the unpublished-version fallback where it is. Moving the install into the scaffolder is explicitly out of scope; if the implementer concludes it is needed, that is a fork to report, not a rider.

Triage: this comment comes from the triage seat Routine; not a claim.

先复验前提

⚠️ 本卡建立在 PR #9115（#9017，让脚手架把 Dockerfile 运行时镜像 tag 钉到解析出的 @objectstack/cli 版本）之上。它已不在开放 PR 列表中 ⇒ 先确认它是否已合并到 main，并在合并后的 ref 上复验：脚手架的钉版动作确实发生在其 install 之后（因而被 --skip-install 抑制）。若前提已变 ⇒ ⛔ 停手回报，不要硬做。

缺口

.github/workflows/scaffold-e2e.yml 用 --skip-install 生成，随后由 workflow 自己 npm install ⇒ 脚手架自身的 post-install 从不运行。于是：

e2e 构建并启动的是未钉版形状（FROM ghcr.io/objectstack-ai/objectstack:latest）
真实 npx create-objectstack 用户拿到的是已钉版形状
⚠️ 而该 docker leg 自己的注释宣称它「exercises the exact Docker path a real npm create objectstack user ships」—— 这句话现在只对 --skip-install 变体成立

⇒ 钉版形状有单测（packages/create-objectstack/src/runtime-image.test.ts 断言脚手架输出），缺的是端到端那一条腿。

方向：卡片给了推荐，接受它

卡片写「neither is obviously right; the first is much cheaper and covers the actual regression risk（钉版动作静默不发生）」⇒ 走第一条：额外生成一个不带 --skip-install 的小项目，仅断言产出的 Dockerfile 已钉版，⛔ 无需 docker build。

⛔ 不要走第二条（把 install 移进脚手架）：那会连带搬走 workflow 里的未发布版本回退逻辑（把 @objectstack/* range 改写为 latest 再重新盖 engines.protocol），卡片明说那是「a deliberate design worth its own card rather than a rider」。若你测出第一条不可行，⛔ 不要自行改走第二条——回报并停手。

验收判据（请在回报中给出）

⭐ 消融：把钉版逻辑临时打断（或指向未钉版产出），证明新增的这条腿会红，且红的信息指名是钉版没发生。⇒ 一条不会因缺陷而红的测试不算覆盖。
⚠️ 顺带修正那句现在只对 --skip-install 成立的注释，使其与实际覆盖面一致。

约束

⛔ worktree 优先：git worktree add ../objectstack-9117 -b claude/issue-9117-scaffold-e2e-pinned-shape main。⛔ 永不 git stash。
⛔ 不得编辑 content/docs/releases/。
⚠️ 本轮并发 3 个 dev，API 额度全仓共享且今日塌过三次 ⇒ 省着用；被限流 ⛔ 不连续重试，如实写进回报。
第一次编辑前重读本卡全部评论；若有不同 session ID 的更早认领 ⇒ ⛔ 停手回报。

回报用标准 os-dev-report JSON。⚠️ 实测与卡片冲突时以实测为准并如实报告差异。

Landed the card's first shape: a new scaffold-e2e step scaffolds a second throwaway project WITHOUT --skip-install (keeping --skip-skills, which runs after the pin) and asserts the emitted Dockerfile's FROM tag equals the @objectstack/cli version the project resolved — no docker build.

Suggested: unlabeled (concrete gap) in objectstack, backlink to #9117 and PR #9142."

}

Two steps I could not complete, both GitHub API rate limiting (API rate limit already exceeded for user ID 314343378 — shared identity, 3 concurrent devs; not retried in a loop per dispatch constraint):

skip-changeset label on PR test(scaffold-e2e): cover the pinned Dockerfile shape a real scaffold ships #9142 is NOT applied. The PR is .github/workflows/**-only, so it needs it. I deliberately did not blind-write the label set: the write is a whole-set PUT and the read-back that would have told me what the labeler bot applied kept failing, so a bare write risked wiping those. Needs one read + union write.
PR body not read back after create, so the sanitizer's handling of it is unverified. Nothing in it depends on a <+letter span.

Correction to the report above (no edit-comment tool available, hence a follow-up): the rate limit eased on the REST read path right after posting, so both blocked steps are now done — item 1 and 2 of that comment are stale.

skip-changeset is applied to PR test(scaffold-e2e): cover the pinned Dockerfile shape a real scaffold ships #9142. Read first, union written, read back: ["ci/cd", "size/s", "skip-changeset"] (labeler had applied ci/cd, size/s).
PR body read back and intact — no sanitizer truncation, footer kept in its session-URL form, head sha d1ae6ce7e.

Still blocked, and not retried further: search_issues, issue_read get_labels and list_issues all keep returning API rate limit already exceeded for user ID 314343378, so search-before-file could not run and the one out-of-scope finding (the option-2 fork — relocating the unpublished-version fallback into the scaffolder, which would remove this leg's warn-and-skip degradation) is still unfiled, with its proposed content in the report above.
