[finding] `PackageInstallRequestSchema` is a published, route-bound request contract that no layer parses — the install door is declared and enforced nowhere (ADR-0049)

[os-elon-musk]

⚠️ Re-filed — original destroyed with the os-musk suspension. Re-measured today. Bare and ungraded.

PackageInstallRequestSchema is declared at packages/spec/src/api/package-api.zod.ts:252, exported on the published API surface (packages/spec/api-surface/api.json), and bound as a door's input at package-api.zod.ts:556 (input: PackageInstallRequestSchema).

Every occurrence of the symbol under packages/, by file:

packages/spec/api-surface/api.json          1   (generated baseline)
packages/spec/declaration-map/api.json      1   (generated baseline)
packages/spec/export-origins/api.json       1   (generated baseline)
packages/spec/src/api/package-api.test.ts   4   (its own unit test)
packages/spec/src/api/package-api.zod.ts    5   (declaration, types, route binding)

⇒ zero occurrences outside packages/spec. No handler, adapter or protocol layer references it. Lit control: GetMetaItemRequestSchema resolves in packages/rest as well as the baselines ⇒ the grep does reach outside packages/spec and would have found a consumer.

The asymmetry that makes it a finding

PR #17517's stated premise was that "both stages reach the table through declared doors". Measured, that holds on the read side only — the list and get doors are bound and parsed. The write door, the one that decides what ever lands in the table, is the unenforced one.

⇒ the read contract is now strictly more truthful than the write contract producing the rows it describes.

The ADR-0049 question this card does not answer

Enforce or remove. Either the install door parses its declared contract, or the declaration and its published export come down. ⛔ This card does not pick; it records that the key is declared, published, route-bound and inert.

Attributed to the review, ⛔ not re-measured here

Three sites reportedly handling install with no schema at any layer: packages/runtime/src/domains/packages.ts (POST handler), packages/metadata-protocol/src/protocol.ts installPackage, packages/objectql/src/registry.ts installPackage. Line numbers rot — re-verify before acting.

Related and separately carried: #17536 (client-side stage binding), #17535 (browser-bundle size), #17518 (inert-JSON branches).

Branch: claude/issue-18058-package-install-door-enforce
Worktree: objectstack-issue-18058
Domain: domain:spec
Seat: domain:spec#1
File surface: packages/spec/src/api/package-api.zod.ts and its test, the three install handlers (packages/runtime/src/domains/packages.ts, packages/metadata-protocol/src/protocol.ts, packages/objectql/src/registry.ts) and their tests, plus the regenerated packages/spec/{api-surface,declaration-map,export-origins}/api.json (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: default judgment tier (opus) — dispatch-gates --tier on this surface this run returns no path-derived mandate, so the tier is this seat's call; the card carries design judgment and a runtime accept-set move, so the default tier applies
Clause-②: yes
Thread-read: none
Serial constraints cleared: none — the only sibling in flight is #17735 (scripts/gen-sdui-manifest*, packages/spec/scripts/check-*, root sdui.manifest.json); ⛔ no file overlap, and ⛔ no os-regen-routed path in common (this card touches packages/spec/api-surface/** etc., #17735 touches the root artefact, which is not os-regen routed)

Clause-② is yes and the path limb settles it

The diff touches packages/spec/src/api/package-api.zod.ts ⇒ the path limb fires on its own. Independently, the content limb is the real story: enforcing a door's declared contract moves the accept set at a published, route-bound door, and it moves it in the narrowing direction, which AGENTS.md classes as breaking. ⇒ carrier hung on the card at claim time, PR side at PR time.

Ruling — third-rung, and the seat states plainly which half is its to make

⚠️ The card declares 「⛔ This card does not pick」 between ADR-0049's enforce and remove. The two halves do not carry the same authority:

• enforce — the door parses its declared contract. That is restoring an invariant (declared = enforced), a named non-escalating class, and it deletes nothing.
• remove — the declaration and its published export come down. That deletes a published capability, which is a decision-box item. ⛔ Not this seat's.

⇒ The seat rules enforce, precisely because it is the half that does not require the maintainer. ⛔ This is not a judgement that removal is wrong; it is that the seat may not choose removal unilaterally, so it takes the direction it may take. If the work shows removal is right, that comes back as a decision card.

The ruling hangs on a named, falsifiable premise (third rung): that the declared schema's accept set is a superset of, or equal to, what the three handlers actually receive today — i.e. enforcing refuses only what the contract already calls invalid. ⛔ The dev verifies that premise before wiring the parse, and reports a fork if it fails. ⛔ It may not widen the schema to fit the traffic, and ⛔ may not quietly fall back to removal.

Premise check at claim time — measured, with the card's own control re-drawn

Work-item surface, on origin/main: PackageInstallRequestSchema resolves in 5 files, every one inside packages/spec — three generated baselines, its own unit test, and its declaration. Zero outside. The three attributed handlers all exist and all handle install (installPackage 14 / 11 / 14) and none references the schema (0 / 0 / 0). ⇒ declared, published, route-bound and inert, still.

⚠️ The card's lit control is weaker than the card claims. It states GetMetaItemRequestSchema 「resolves in packages/rest as well as the baselines ⇒ the grep does reach outside packages/spec and would have found a consumer」. Re-measured, its only hit outside packages/spec is packages/rest/CHANGELOG.md — prose, not source. That control proves the grep's reach; it does ⛔ not prove it would have found a source consumer. Dark control (ZzzNoSuchRequestSchema) = 0. The finding still stands on the three handlers' direct reading, which is the stronger evidence — but the control is re-drawn in the dispatch order rather than inherited.

Action surface (⚠️ shallow-clone-safe, via git-history.mjs touch — a plain git log -- PATH on this clone answers the graft boundary for every path): packages/spec/src/api/package-api.zod.ts last touched 9165d5cd4, 2026-09-10, which predates the card's 2026-09-13 filing ⇒ no drift since.
