cli: `create-objectstack` emits TypeScript `^6.0.0` while `os init` / `os create` emit `^5.3.0` — generate the on-ramp's version policy from the same constants at build time (item 4 of #15531)

[os-zhuang]

Filed by the director seat under the #15531 ruling (decision batch #66, 2026-09-07, option B).

Why

npx create-objectstack is the documented on-ramp (13 doc pages). It declares typescript: ^6.0.0 for a new project while os init and os create declare ^5.3.0 from the shared emission policy (PR #15974). Two projects created the same day get different TypeScript majors depending on which entry point the reader followed. The structural cause: create-objectstack cannot import from @objectstack/cli, so the shared constants never reach it.

Scope

• Generate create-objectstack's version pins from the same policy source at build time (a small generation step that inlines the shared constants into the package, with a check that fails when the inlined values drift from the source — the repo's usual generated-file pattern).
• Decide the actual TypeScript range once (the shared policy's value wins unless the cli seat records a reason the on-ramp needs a different one — record it here).
• Pin: a test that the three scaffolders emit identical typescript (and pnpm / engines) ranges.

Acceptance

• identical ranges across create-objectstack, os init, os create
• drift check present and green
• changeset for create-objectstack

Dispatched to a dev in a dedicated worktree. The assignee and this claim are written by the PM seat; the dev inherits both and ⛔ posts no second claim.

The range decision this card asks the cli seat to record

The card says:

Decide the actual TypeScript range once (the shared policy's value wins unless the cli seat records a reason the on-ramp needs a different one — record it here).

Recorded: the shared policy's value wins — ^5.3.0, the one os init / os create already emit from PR #15974's shared emission policy. There is no reason for the on-ramp to differ, and that is the whole point of the card: two projects created the same day must not get different TypeScript majors because the reader followed a different entry point. create-objectstack's ^6.0.0 is the outlier, not the standard, and it is outlying only because the package structurally cannot import from @objectstack/cli — a plumbing accident, never a decision anyone made.

⚠️ One measured exception, and the dev is asked to look for it rather than assume it away. If the repo itself has moved to TypeScript 6 — its own devDependency, its engines, or the emission policy being stale against what the monorepo actually builds with — then ^6.0.0 is the right value and ^5.3.0 is the stale one, and this card would be pinning three scaffolders to a version the repo has left behind. That is a finding to report, ⛔ not a range to pick silently in either direction. Measure which of the two is stale before generating anything.

⇒ Absent that finding: ^5.3.0 from the shared policy, all three scaffolders identical.

Grade

⛔ Not re-graded. priority:p3 stands as the director seat filed it under the #15531 ruling (decision batch #66, 2026-09-07, option B). The direction is ruled — generate the on-ramp's pins from the same policy source at build time, with a drift check — so this is execution, ⛔ not a design question to re-open.

Why the drift check is the deliverable, not the version bump

Editing create-objectstack's ^6.0.0 to ^5.3.0 by hand would satisfy the acceptance box and leave the defect exactly where it is: the two values would agree today and diverge again the next time the shared policy moves, silently, for the same structural reason. The generation step plus a check that reds on drift is what actually closes this — the repo's usual generated-file pattern. A pin that cannot go red is not a pin.

"summary": "The card's premise holds: on origin/main create-objectstack's bundled template declared typescript: ^6.0.0 while os init / os create emitted ^5.3.0 from the shared SCAFFOLD_* constants. STALENESS MEASUREMENT (the exception the PM asked me to look for, and it did NOT fire): the repo's own devDependency is typescript@^6.0.3 in the root manifest and every workspace package, and root engines carries only node: >=22.0.0 — but neither range is stale, because they answer different questions and the repo says so in one sentence on a live doc page: content/docs/getting-started/index.mdx reads "ObjectStack works with TypeScript 5.3+, but the project itself is built and tested against TypeScript 6.x", and content/docs/deployment/troubleshooting.mdx repeats the same floor. ^6.0.3 is the toolchain this monorepo builds ITSELF with; 5.3+ is the floor a scaffolded project DECLARES to its user, i.e. a support promise. create-objectstack's ^6.0.0 matched neither (it is not the repo's 6.0.3 pin either). So the shared policy's ^5.3.0 wins exactly as recorded, and NO shared-policy bump is owed. Landed: (1) scripts/sync-scaffold-emission-policy.mjs reads the constants out of packages/cli/src/commands/init.ts and stamps devDependencies.typescript and engines.pnpm into every bundled template, discovered by reusing sync-template-versions.mjs's walk; create-objectstack's build runs it first, the way packages/spec's build runs gen:schema. (2) pnpm check:scaffold-emission-policy (--self-test + --check), its own step in lint.yml, reds on drift and its failure text refuses the hand edit by name. (3) The three-scaffolder pin extends packages/cli/test/scaffold-emission-policy.e2e.test.ts and DRIVES the on-ramp (spawns bin/create-objectstack.js into a temp dir, reads the emitted package.json) rather than restating constants or reading the file the generator writes. (4) Changeset for create-objectstack (minor). Two gate-required wiring pieces came with it: the cross-package input declarations for @objectstack/cli (on-ramp bin, bundled package.json, the generator) mirrored into turbo.json, and a NOT_DRIVER_MANAGED merge disposition in scripts/regen-artifacts.mjs (the template package.json is MIXED — the generator rewrites two values and reproduces none of the rest). DOCS-DRIFT SWEEP (PM follow-up): the bot listed three pages plus the release page; ZERO are falsified. It anchored on os init because this diff touches packages/cli/src/commands/init.ts — that change is 100% COMMENT lines (git diff filtered to non-comment, non-blank added/removed lines returns nothing; 25 insertions / 10 deletions, all prose), because the paragraph saying create-objectstack's ^6.0.0 'is deliberately NOT unified here' became false and now records the generation mechanism and the range measurement. Listed but accurate, left alone: getting-started/your-first-project.mdx (says a standalone project does not need TypeScript pre-installed and that it arrives as a dev dependency — version-free about typescript; its engines: { protocol: '^17' } belongs to sync-template-versions.mjs and this diff does not move it); getting-started/examples.mdx (no version statement at all — every typescript hit is a fenced-block language tag); deployment/cli.mdx ('TypeScript setup', 'TypeScript availability', the same protocol stamp — prose about the language, not a range). content/docs/releases/v17.mdx NOT touched and nothing owed: it states the engines.node >=18 to >=22 move and the engines.protocol stamp, and carries no typescript range and no scaffold engines.pnpm, so this diff falsifies nothing there and no docs-only follow-up is needed. Hand sweep past the bot's declared blind spot, over content/, skills/ and the package READMEs for typescript@, a typescript range literal, 'TypeScript N.x' prose and scaffold engines: getting-started/index.mdx and deployment/troubleshooting.mdx state the 5.3+ floor and this diff moves the on-ramp INTO agreement with them; and the sweep found one carrier the bot structurally could not name — see out_of_scope_findings.",
