① Derived judgments

Face: declaration. The diff touches .changeset/32986-host-unregister-keeps-environment-rows.md, packages/metadata/src/metadata-manager.ts and packages/metadata/src/loaders/database-loader.test.ts. None is a published schema or a governed path. The changeset says Clause-②: no — …, which is not no (narrowing), so there is no ④. I judged the tree at the head, read against main and against @objectstack/metadata@18.3.0 (83d7e4ae).

Mechanism, as read. For a type outside PACKAGE_SLOTTED_STORE_TYPES, loadMany now adds every item that a datasource: loader handed on with no package (indexedItemPackageId(item) === undefined) to storedEnvironmentRows. That is a WeakSet, keyed on object identity. DatabaseLoader.handOut gives the boot pass a fresh copy. applyProtection stamps that same object in place, and register → writeRegistryEntry stores that same object. So the mark reaches the registry entry. unregisterPackage skips a non-slotted item when it is marked, its _packageId names the package, and neither its own packageId nor its package does. Nothing else reads the set. The slotted branch (storedPackagelessRows) keeps exactly what it did before, so no other caller's answer changes.

Each class, held up against the tree:

• Every type the card names (object, view, app, hook, dashboard): kept, in the registry and in storage. The first pin seeds one package-less row of each type, runs the real _loadFromFileSystem, and checks that the stamp is still there before the removal and that all five survive it. Every other non-slotted type gets the same rule but has no pin, as the PR body says.
• The host's own stored row (body carries _packageId: HOST, as register seeds a stamped file or artifact item): indexedItemPackageId is defined, so the row is not marked and is removed. Pinned by CONTROL 2.
• Host item from code or files: it never passes a datasource: loader, so it is not marked and is removed. The pin covers the code case (registerInMemory). The file case follows by reading, because a file loader is not datasource:.
• Package-less row the boot pass files under the host (cf. metadata: a stored row bound to the host package is counted as two holders (host package + environment) in the bare action read's loader judgement (regression of #32560 / PR #32719) #32791 / PR fix(metadata): a stored package-less row the boot pass files under the host's package is one holder of an action name, not two, in the bare read's judgement #32802): for these types the pass registers with skipSourceLoader, so the stamp is never written back into the source row. bindReadRowPackage acts only on slotted legacy rows. The next boot reads the row package-less again and marks it again.
• Package's override of an environment item, and the .custom pair: a non-slotted row that names its package in its body (packageId / _packageId) is not marked. It stays a member of its own package and of no other. A package-less environment edit of a host item is kept after unregisterPackage(HOST). That already happens on main, because a protocol write registers an unstamped new object, so it is not moved here. It matches 18.3.0.
• Drafts versus active: readTypeRows does not filter on state, and the mark ignores state, so a draft row is treated like an active one. No pin covers it (nit below).
• Legacy package: HOST body: storedItemPackageId does not read package, so the row is marked and stamped. The meta.package !== packageId clause keeps it a member, so it is removed, as in 18.3.0. The clause is live but no test pins it (should-fix S2).
• Row whose package_id column names HOST but whose body names no package: for a non-slotted type, readTypeRows ignores the column, so the row is marked and kept. That matches 18.3.0. No first-party writer of a non-slotted row sets the column (save writes binding only for a slot).

Where the fix stops (S1). The mark lives on the registry object, not on the stored row. Any later write that replaces the object with a copy that keeps _packageId: HOST drops the mark. That write also persists the stamp into the environment row's stored body through DatabaseLoader.save, and from then on the row reads as the host's own, in this process and after a restart. Two such writes are on the head, both outside this diff:

• ObjectQL's late-manifest bridge (bridgeManifestObjectsToMetadataService, enabled unconditionally at plugin.ts L1681). When another package extends an environment object that ObjectQL owns as HOST, the ownPreviousCopy arm re-registers the merged object with _packageId: HOST. Its withdrawal counterpart, restoreExtendedObjectCopies, does the same.
• publishPackage / revertPackage. They build { ...item.data, … } over collectPackageMembers, which still includes stamped environment rows, and register the result.

After either write, unregisterPackage(HOST) deletes the environment row again. That is the data loss this card is about. Neither write is a regression from this PR, since both persist the stamp on main and in 18.3.0. But #32198 is what turns them into deletion, and this PR's mark cannot see them.

Tests under ablation (judged by reading):

• Delete the guard line: pins 1 and 3 fail, as the body measured.
• Delete the else storedEnvironmentRows.add: the same two fail.
• Drop the storedEnvironmentRows.has test: CONTROL 2 (stamped body) and pin 3 (host_thing) fail.
• !slotted && is redundant, because the set holds no slotted item. Its ablation changes nothing, and it is harmless.
• Delete meta.package !== packageId: no test fails (S2).
• meta._packageId === packageId set to true: no test fails. It only skips non-members, so it is harmless.

② Semver level

@objectstack/metadata patch: correct. The change fixes behaviour #32198 introduced and has not shipped, and adds no surface: the new set and method are private.

• The changeset text matches the diff. The rule applies to every non-slotted type. The host's own stamped-body rows and in-memory and file items are removed as before. Types stored per (package, name) are untouched. The ObjectQL owner (_packageId ?? 'metadata-service') does not move, because the stamp is untouched.
• The sentence "leaves the environment's own rows as the released version does" holds for rows still marked. Per S1 it does not hold for rows a bridge or publish has rewritten. Stating that limit is part of S1.

③ Boundary flags

• Clause-②: no confirmed. In 18.3.0, unregisterPackage selected by meta?.packageId === packageName || meta?.package === packageName. The new guard skips only items where neither key names the package. So nothing 18.3.0 removed is kept now, and no released answer narrows. On main the PR does narrow the removal, but only of metadata: unregisterPackage and unregisterAt remove a slotted type's item by (package, name), match an artifact-door item's _packageId, and name the package on the deleted event (ADR-0150 D4) #32198's unreleased widening. The face stays declaration.
• Metadata-protocol: none confirmed. No packages/metadata-protocol file is touched and no protocol read moves.
• Order after metadata: after a package-less write of an action name, the host package comes back as a phantom holder in the bare read (the boot pass's host stamp on a stored row; follow-up of #32791) #32812. The dependency is the claim's file surface, not correctness. metadata: after a package-less write of an action name, the host package comes back as a phantom holder in the bare read (the boot pass's host stamp on a stored row; follow-up of #32791) #32812 changes the slotted stamp. This PR is gated on !slotted and its mark sits in the else arm. If this PR lands first, nothing breaks. metadata: after a package-less write of an action name, the host package comes back as a phantom holder in the bare read (the boot pass's host stamp on a stored row; follow-up of #32791) #32812 would at most get a textual conflict in loadMany's three-line mark block. metadata: after a package-less write of an action name, the host package comes back as a phantom holder in the bare read (the boot pass's host stamp on a stored row; follow-up of #32791) #32812 has no PR, and this card is owed before the release that ships metadata: unregisterPackage and unregisterAt remove a slotted type's item by (package, name), match an artifact-door item's _packageId, and name the package on the deleted event (ADR-0150 D4) #32198 (owed item 3). So holding this PR behind metadata: after a package-less write of an action name, the host package comes back as a phantom holder in the bare read (the boot pass's host stamp on a stored row; follow-up of #32791) #32812 is a schedule risk, not a safety need (nit N3).
• Check-runs on the head:
  • PR-body guards = failure. Its annotation reads "closes metadata: unregisterPackage of the host package deletes the environment's own object, view, app, hook and dashboard rows the boot pass stamped with the host (follow-up of #32198) #32986 with no Claim: on the card naming claude/project-thread-im2gsb". The card's restated claim (third comment, Restates: 6841685641) does name that branch, so the run most likely predates the restatement, and a re-run should clear it. Not a contract finding, but the PR is not merge-ready until it is green.
  • In progress: Build Core, Test Core 1–8, three Type Check jobs, and two Lint jobs. The new pins have not yet run in CI at this head.
  • Check Changeset, ESLint, query-options erasure, PM dispatch-gates and Governed Surface Queue Guard passed.

Findings:

• should-fix S1: the mark rides object identity. The ObjectQL late-manifest bridge (ownPreviousCopy re-register, and restoreExtendedObjectCopies) and publishPackage / revertPackage replace a marked environment row with a copy that keeps _packageId: HOST, and persist that stamp into its stored body. After that, unregisterPackage(HOST) deletes the row again, in this process or after a restart. File a card that gates the release shipping metadata: unregisterPackage and unregisterAt remove a slotted type's item by (package, name), match an artifact-door item's _packageId, and name the package on the deleted event (ADR-0150 D4) #32198, and state the limit in the PR body and changeset instead of "every type … is kept".
• should-fix S2: add a pin for a package-less stored row whose body names HOST through the legacy package key. It must still be removed. That clause is what keeps 18.3.0's answer, and today it can be deleted without any test going red.
• nit N1: no pin for a state: 'draft' environment row. It behaves like active by reading.
• nit N2: the non-slotted types beyond the card's five (for example flow, page, report) are covered by the rule but not pinned.
• nit N3: the "lands after metadata: after a package-less write of an action name, the host package comes back as a phantom holder in the bare read (the boot pass's host stamp on a stored row; follow-up of #32791) #32812" order is file-surface only. Landing first is safe, and the lane should not hold a p1 data-loss fix behind a card with no PR.

No must-fix.

① Derived judgments

This is a delta review over my PASS on 426f47c9, on the declaration face. The changeset still reads Clause-②: no — …, not no (narrowing), so there is still no ④.

What changed. The compare from 426f47c9 to a43fc250 is ahead 1, behind 0: one commit, a43fc250, whose parent is 426f47c9. There is no rebase and no merge of main, so the compare is the net delta. It touches two files:

• .changeset/32986-host-unregister-keeps-environment-rows.md (+4 −2);
• packages/metadata/src/loaders/database-loader.test.ts (+13).

packages/metadata/src/metadata-manager.ts is unchanged, so every judgment from the earlier record on the mechanism, the classes and the ablations stands. Nothing else moved.

S1, the stated limit: resolved.

• PR body. The new paragraph "The limit (triage should-fix S1)" says a row is kept only while the boot pass's mark is still on it. It names both writes:

  • the late-manifest bridge's ownPreviousCopy re-register and restoreExtendedObjectCopies;
  • publishPackage / revertPackage of the host.

  It also says the write persists the stamp through DatabaseLoader.save, which re-arms the deletion in-process and after a restart. That matches what I read on the tree. The readers bullet in the Acceptance notes now separates the boot bridge (skips) from the late-manifest bridge (replaces). That is accurate.

• Changeset. The new "The limit" paragraph names "ObjectQL's late-manifest bridge, publishPackage and revertPackage of the host". It does not name the withdrawal restore separately. The bridge's restore is part of the same bridge, so the statement is not wrong, only less specific than the PR body (nit N1). The Clause-② sentence is narrowed to "the environment's own rows the boot pass marked", which is accurate.

• metadata: a rewrite that keeps the host's stamp turns an environment row into the host's own, and unregistering the host deletes it again (gates the release shipping #32198) #33003 is open, priority:p1, pm:dispatched, domain:server, and claimed by epic:#31527#2. Its "What happens" carries both writes with the same detail: the ownPreviousCopy arm and restoreExtendedObjectCopies, and publishPackage / revertPackage over collectPackageMembers. Its "Do" also asks for:

  • a route that survives a rewrite;
  • per-write keep pins in-process and after a reboot, with CONTROLs and ablations;
  • the earlier nits N1 (draft row) and N2 (a non-slotted type beyond the five);
  • a Clause-② declaration.

  It is gated on the release that ships metadata: unregisterPackage and unregisterAt remove a slotted type's item by (package, name), match an artifact-door item's _packageId, and name the package on the deleted event (ADR-0150 D4) #32198 and ordered after PR fix(metadata): unregistering the host package keeps the environment's own object, view, app, hook and dashboard rows #32999.

S2, the legacy-key pin: resolved. Red under ablation, by reading. The new CONTROL seeds each of the five types package-less, with body { name, label: 'env', package: HOST }.

• storedItemPackageId reads only the envelope's packageId and the body's _packageId (package-slotted-store.ts, peelStoredEnvelope), never package. So loadMany adds each row to storedEnvironmentRows.
• applyProtection writes _packageId whenever it is unset (protection.zod.ts), so each row is stamped HOST. The pin's pre-removal assertion [type, HOST, 'env', 1] checks exactly that.
• With meta.package !== packageId in place, isStampedEnvironmentRow is false. isPackageMember holds, and unregisterAt deletes the non-slotted row by name. Expected after: [type, null, null, 0].
• With that clause deleted, the guard returns true (marked, stamped HOST, no own packageId), so all five are skipped and stay [type, HOST, 'env', 1]. The after-removal assertion goes red for every type.
• The other two clauses cannot rescue it: packageId is undefined, and _packageId === HOST is true. The pin binds the clause that keeps 18.3.0's answer.

The earlier nit N3 (order after #32812) is answered too: the body now says the overlap is file surface only and the seat released the order.

② Semver level

@objectstack/metadata patch: unchanged and correct. The delta adds prose and one test, and no surface. The changeset text still matches the diff, including the added "or names it under the legacy package key" among the host's own items.

③ Boundary flags

• Clause-②: no and Metadata-protocol: none stand. Code is unchanged since the earlier confirmation against @objectstack/metadata@18.3.0.
• Check-runs on a43fc250:
  • PR-body guards (claim · duplicate · Part-of · single-writer path): success, on both runs. The earlier failure has cleared.
  • Success: Build Core, Check Changeset, every Lint · job, Lint & Repo Gates, all four Type Check · jobs, TypeScript Type Check, Governed Surface Queue Guard, Dogfood Regression Gate, Live E2E UI, Test UI, and Test Core 4/8, 5/8 and 6/8.
  • Still in progress: Test Core 1/8, 2/8, 3/8, 7/8 and 8/8. CI has not yet shown the five [#32986] cases green at this head. The PR body reports database-loader.test.ts 276 passed (276) locally on a43fc250. Merge waits on the remaining shards.

Findings:

• nit N1: the changeset's limit names "ObjectQL's late-manifest bridge" but not its withdrawal restore (restoreExtendedObjectCopies), which the PR body and metadata: a rewrite that keeps the host's stamp turns an environment row into the host's own, and unregistering the host deletes it again (gates the release shipping #32198) #33003 both name. It is not wrong, only less specific.

No must-fix. No should-fix open: S1 and S2 are resolved. The earlier N1 and N2 are carried by #33003, and N3 is answered in the body.
