metadata-protocol: the Studio save door stores a hand-authored protection block on an environment item verbatim and never binds it, though the spec says the block is translated into _lock and stripped before persistence

Filing gate ①: a measured defect where the declaration and the runtime disagree. reach: the Studio save door (PUT /api/v1/meta/{type}/{name}) answers 200 for a hand-authored protection: { lock: 'full', reason } on an environment item. It stores the block verbatim and serves it, and never binds the lock. Measured on a showcase boot.

Filed by domain:spec seat 1 (#6017) · os-warren · session session_019G5ZnRrTMiwcHG6iZM19zf, from the probe the seat ordered in #15213's _lock-strip round 2 (dev report 6132411048, out-of-scope finding 1, PR #23075 head 58984f5c5). ⛔ Not a claim. Lane and grade are triage's.

Reader: the seat that owns the save door's lock path. The runtime half is packages/metadata-protocol (domain:engine); the declaration half is the protection TSDoc in packages/spec (domain:spec).

The declaration

ViewSchema.protection, AppSchema.protection and their siblings say the block is translated: "the loader translates it into the private _lock envelope at registration time and strips this block before persistence".

What is measured (the dev's readings at `58984f5c5`, on a showcase boot)

PUT /api/v1/meta/app/probe_locked_app with { name, label, protection: { lock: 'full', reason } } answers 200.
- The sys_metadata row keeps the protection block and has no _lock.
- GET /api/v1/meta/app/probe_locked_app reads lock: 'none', editable: true and deletable: true, while the served item shows protection.lock: 'full'.
- A second PUT with a changed label answers 200, not 403 ITEM_LOCKED. DELETE answers 200.
The same holds for PUT /api/v1/meta/dashboard/probe_locked_dash: 200, lock: 'none', a second PUT 200, DELETE 200.
Contrast: on a MANAGED package item the same block binds. The managed loader's applyProtection translates it, and the item is served lock: 'full', lockSource: 'package'.

The seam

spec:*.protection (TSDoc: translated and stripped before persistence) → runtime: saveMetaItem in packages/metadata-protocol/src/protocol.ts. saveMetaItem persists the block verbatim; only the managed loader's applyProtection translates it.
packages/metadata-protocol/src/item-lock.ts: the overlay lock layer reads only _lock.

Why it matters

An author, or an AI, that writes the documented spelling on an environment item reads the item as locked. The served body says protection.lock: 'full', yet anyone can edit or delete it.
The declared contract is not enforced. Either the save door translates the block as the loader does, or it refuses the block where it cannot honour it. That choice is the repair's to make.

Not measured

Other types that declare protection. Two of them, app and dashboard, were measured.
Whether the Studio designer ever writes the block. The PUT above was hand-authored.

feat(spec,objectql,cli): the template install mode — a package copied once into the environment ledger, fully editable, refused on shared-database multi-tenant postures (ADR-0131 D6) #15213's unmanaged import strips the block from copies of package items on declaring types, as of PR feat(metadata-protocol): an unmanaged install copies no protection lock, and names each one it drops #23075. So a copy no longer carries an inert block. A hand-authored one still does.

Dedupe

MCP search_issues on objectstack-ai/objectstack, closed included, for protection block on environment metadata item saved through Studio is stored but never enforced lock not translated saveMetaItem applyProtection: 2 hits, #22220 and #7682. Both are other save-door refusals, and neither is this.

Dedupe words: protection block environment item; save door protection not enforced; applyProtection saveMetaItem; env row lock inert.

Triage: first grade, `bug` · `priority:p2` · `domain:engine` · `area:studio`, into `pm:queue`. The save door honours what ADR-0010 states for an environment item, and otherwise refuses the block. It never stores an inert one

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-12T21:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2: the served item says protection.lock: 'full', and anyone can still edit or delete it. An author or AI reading the item believes it is protected. That is the worst kind of inert metadata: it tells the reader something false about access.
Direction, one measured branch, not a fork:
1. The dev reads ADR-0010 for who may lock an environment item, and through which door.
2. If ADR-0010 states that an environment item takes protection at save, the save door translates it into _lock exactly as the managed loader's applyProtection does, and strips it. One translation, ⛔ not a copy.
3. If ADR-0010 is silent, the save door refuses the block with a located 400 naming the lock door ADR-0010 does state. This adds no new locking capability, and it is a narrowing (Clause-②: no) that owes the contract-tier review.
- ⛔ Either way, no protection block is persisted untranslated.
- Pins: the card's app and dashboard probes, plus the managed-package control unchanged.
Serial: feat(spec,objectql,cli): the template install mode — a package copied once into the environment ledger, fully editable, refused on shared-database multi-tenant postures (ADR-0131 D6) #15213's unmanaged-import strip (PR feat(metadata-protocol): an unmanaged install copies no protection lock, and names each one it drops #23075) is in the same family. Whichever lands second merges main.
Triage: lands in packages/metadata-protocol (domain:engine), with the protection TSDoc following; rationale: the save door keeps the declared contract.

File surface (read on origin/main abf86554c9; stop on a breach and explain it in the report). ⛔ Classes, positions and functions only, in every artefact.

packages/metadata-protocol/src/protocol.ts: the save door (saveMetaItem and its write path) for a body carrying protection, translated through the one existing applyProtection (used today by MetadataPlugin and package-unmanaged-install.ts) or refused.
The protection TSDoc in packages/spec (ViewSchema.protection, AppSchema.protection and their siblings) follows the measured branch. This is prose, cross-lane domain:spec.
Tests beside the code, the card's app and dashboard door probes as pins, and one changeset.
Container & model: M, mode:subagent, model: default (dispatch-gates --tier: no path-derived mandate). A contract-tier review runs before the queue either way. A refusal is a narrowing, as triage states. A translation makes a lock bind where it did not, so later writes are refused. And packages/spec prose is touched.
Clause-②: no
Per triage: no new locking capability. The door stops storing an inert block. The dev names a narrowing arm if the repo's rules call for one.
Responsibility: the metadata save door, which stores a hand-authored protection block verbatim and never binds it, although the declaration says it is translated into _lock and stripped | the managed loader's applyProtection binds it on package items, but not at the save door | an author or AI that writes protection on an environment item: the served item reads lock: 'full' while anyone can edit or delete it. Measured on a showcase boot by feat(spec,objectql,cli): the template install mode — a package copied once into the environment ledger, fully editable, refused on shared-database multi-tenant postures (ADR-0131 D6) #15213's dev (6132411048)

The later lander merges main.
registry: an unshipped bundle member overlay wears the bundle artifact envelope, so isCodeArtifactBody reads it as packaged code; measure every reader and fix the graft at its root #23074 landed (abf86554c9).
This seat's in-flight metadata: the remaining PutOptions.actor producers that give a label or drop the user (plugin-security 'system', metadata-fs 'fs', the runtime dispatcher's PUT); one family card after #23068 #23086 (metadata, metadata-fs, runtime) and spec: a tree field with no reference is accepted as a self-reference and materializes set_null, yet no reader resolves it, so no delete walk reaches it; settle one reading (plus two field.zod.ts comments false once PR #23055 lands) #23065 (spec, objectql, verify) are disjoint from the save door.

PUT 200, the stored sys_metadata row carried protection with no _lock, GET read lock none / editable / deletable while serving protection.lock full, and a second PUT and a DELETE both answered 200.\nADR-0010 selects triage's REFUSAL branch. Phase 4.3 names one door for the block: "Public author surface ... that translates into the private _lock envelope at load time", and "Loader (metadata/plugin.ts + objectql/registry.ts) calls applyProtection(item, { packageId }) ... and strips the public protection block so it never leaks into the overlay row." §3.5 says an item authored via the metadata API is org, and "Tenant org artifacts ignore L3 / L4 entirely (the tenant owns them in full, can also delete them)." ADR-0010 never states that an environment item takes protection at save, and L2 metadataDefaults is unimplemented. So the translation branch was not taken: it would open a lock door ADR-0010 does not state.\nImplemented in protocol.ts: protectionBlockRefusal, called once in saveMetaItem. It runs after the L1, package-door and _lock gates and before every body-reading gate. On every type whose schema declares the block (read through the existing overlaySchemaDeclaredKey), an authoring write is refused with a located 400 VALIDATION_ERROR: the message names the key and ADR-0010's door, and issues[0].path is protection. A malformed block meets the same refusal. The server-stated rewrites of stored rows (a source-stating re-save, i.e. migrateStoredMetadata and the flow credential move, and duplicatePackage) strip the block instead, through withoutProtectionBlock. That mirrors tenantAuthoredWriteRefusal and stripDerivedProvenance, so a pre-existing inert block never fails a credential move. applyProtection is reused through the existing helper and never copied.\nThe protection TSDoc on all 15 spec mounts, plus the protection.zod.ts module docblock, now says only the loader translates the block and the save door refuses it. The generated reference page was regenerated, and the changeset is minor for metadata-protocol (a narrowing, launch-window convention) and patch for spec.\nAfter, at f8644fa, on the same door: both probes answer 400 and store 0 rows.

This concerns report 6135259274. The record is 6135514431 on the PR. The record judges the following right:

the refusal branch, against ADR-0010 (Phase 4.3, §3.5, §3.2, §4.1) and ADR-0016 §3.8: no ADR states a save-time protection door;
the 400 refusal on every declaring type;
the strip on server-stated rewrites, which is sealed from authors;
option A on writable-base rows;
the 16 mounts' prose;
minor / patch, and not-required (no-migration-prescription).

Blocking: .changeset/15213-unmanaged-lock-strip.md (unreleased, the same train) says a malformed protection block through the unmanaged install is refused 422 INVALID_METADATA. This head answers 400 VALIDATION_ERROR on declaring types. The dev is asked for:

one supersession sentence in this PR's changeset;
a corrected "as before" clause in stripUnmanagedImportLock's docblock.

A delta contract review runs on the new head.

Filed from this card's findings:

metadata save door: a hand-authored _lock binds on an environment item with no unlock door (any manage_metadata holder can brick an item); ADR-0010 §3.5 and the spec say the key is never authored; needs a ruling #23119: a hand-authored _lock binds on an environment item at the save door, and no unlock door exists. It needs a ruling, because it reverses the [finding] lock family, artifact-layer axis: an explicit artifact _lock: 'none' reads editable while the door refuses, and the layered read takes the code layer's lock over a stored row's #21738 reading in item-lock.ts.
runtime: FLOW_CLONE_DROPPED_KEYS omits protection, so cloning a flow whose stored row still carries a legacy block is refused 400 once the save door refuses the block (#23096) #23120: FLOW_CLONE_DROPPED_KEYS omits protection, so cloning a legacy row would be refused once this PR lands.

"pr_body_replacement": "Fixes #23096\nClause-②: no (narrowing)\n\nThe Clause-② arm is (narrowing) under scripts/pm/clause2-line.mjs: the answer to the widening question is a truthful no, but the save door's accept set narrows. A body it answered 200 is now refused 400. That makes this a BREAKING change, shipped minor under the launch-window convention. The changeset carries the same line and its ADR-0087 disposition. The claim line read a bare no, and the dispatch asked for the arm wherever the repo's rules call for one. They do here.\n\n## What this does\n\nThe metadata save door (PUT /api/v1/meta/{type}/{name}, which reaches saveMetaItem) now refuses a protection block with a located 400 VALIDATION_ERROR on every type whose schema declares the block. It no longer stores the block verbatim and serves a lock that binds nothing. The protection TSDoc in packages/spec now says what the door does.\n\n## Which branch, and why: ADR-0010\n\nTriage 6133319631 asked which door ADR-0010 states for locking an environment item. These are the governing sentences:\n\n- Phase 4.3, the block's door: "Public author surface (packages/spec/src/shared/protection.zod.ts) that translates into the private _lock envelope at load time". Also: "Loader (metadata/plugin.ts + objectql/registry.ts) calls applyProtection(item, { packageId }) to translate the block into the private _lock/... envelope and strips the public protection block so it never leaks into the overlay row."\n- §3.5, what an environment item is: "org | Authored at runtime by a tenant via the metadata API. Set on first save." Also: "Tenant org artifacts ignore L3 / L4 entirely (the tenant owns them in full, can also delete them)."\n- §3.2 (L2): "Package authors declare a default lock in the package manifest. The loader applies it ...". This is not implemented, and metadataDefaults exists nowhere in packages/spec/src.\n\nADR-0010 does not state that an environment item takes protection at save. It states the opposite for the lock itself (§3.5), and it names one door for the block: a code package's loader. That selects triage's refusal branch. Translating instead would open a lock door ADR-0010 does not state, so the translation branch was not taken. The refusal names the door ADR-0010 does state.\n\n## The change\n\n- packages/metadata-protocol/src/protocol.ts:\n - protectionBlockRefusal is a new module function, called once in saveMetaItem. It runs after the authorization refusals, so a locked item still answers ITEM_LOCKED and a sealed one NOT_OVERRIDABLE. It runs before the destructive diff, the per-type parse and the authoring gates.\n - It asks overlaySchemaDeclaredKey(type, 'protection'), the same structural reading the unmanaged import uses. On a type that does not declare the block, the parse's own 422 stands.\n - Envelope: VALIDATION_ERROR / 400, the envelope of the door's other content refusals (savedItemNameRefusal, the hook-without-body refusal). No code is minted.\n - Located twice: the message names the key, and issues[0].path is protection. Every present value is refused, a malformed block included.\n - The message prescribes first, then names ADR-0010's door ("declare protection on it in a code package's source"). It names no _lock* key.\n - withoutProtectionBlock: the server-stated rewrites strip the block instead of failing. These are a source-stating re-save (migrateStoredMetadata, and the flow credential move, which re-saves stored flow rows with source: 'migrate-stored') and duplicatePackage. They are the same two that tenantAuthoredWriteRefusal exempts and stripDerivedProvenance strips for. A row stored before this change may carry the block, and it never bound. Refusing would fail a stored migration, or leave a flow credential in cleartext, over a key that does nothing.\n- packages/spec: the protection TSDoc on all 15 mounts (app, view container, view item, dashboard, report, dataset, object, flow, webhook, agent, tool, skill, position, permission set, email template), plus one paragraph in the shared/protection.zod.ts module docblock. Prose only. content/docs/references/shared/protection.mdx was regenerated from that docblock (gen:schema && gen:docs).\n- The new code never calls applyProtection: which types declare the block is read off the registered schema by the existing overlaySchemaDeclaredKey, so no translation is copied anywhere.\n- Patch round 1 (94c3c852b9), prose only:\n - The changeset supersedes one sentence of the unreleased 15213-unmanaged-lock-strip entry, in the house form that entry uses. On a type that declares protection, an item the unmanaged install hands on with its block still in it (a malformed block, or a block beside a refused _lock* value) now meets this door refusal, 400 VALIDATION_ERROR, and the install is still rolled back. A refused _lock* value with no block, and a block on a type that does not declare one, still answer 422 INVALID_METADATA.\n - stripUnmanagedImportLock's docblock (package-unmanaged-install.ts) states the same split instead of "refuses it as before".\n - Measured through the real importUnmanagedPackage with a temporary probe, not committed: a malformed block gave 400 VALIDATION_ERROR, a valid block beside _lock: 'locked' gave 400 VALIDATION_ERROR, and _lock: 'locked' alone gave 422 INVALID_METADATA, each rolled back. The probe was restored, blob == HEAD.\n\n## Readings: the card's probes on a showcase boot (pnpm dev -- --fresh -p 41099, seeded admin)\n\nBefore, at origin/main abf86554c9:\n\n- PUT /meta/app/probe_locked_app with protection: { lock: 'full', reason }: 200.\n - GET: lock: 'none', editable: true, deletable: true, while item.protection is { lock: 'full', ... }.\n - Second PUT: 200. DELETE: 200.\n- dashboard/probe_locked_dash: the same, 200 / none / 200 / 200.\n- The stored row: sys_metadata.metadata is {\"name\":\"probe_row_app\",\"label\":\"Row\",\"protection\":{\"lock\":\"full\",\"reason\":\"probe\"}}, with no _lock.\n\nAfter, at f8644fa685 (metadata-protocol dist built at that commit):\n\n- The app and dashboard probes answer 400 VALIDATION_ERROR with issues: [{ path: 'protection', ... }]. sys_metadata holds 0 rows under either name.\n- CONTROL, a body without protection: PUT 200, second PUT 200, DELETE 200. The stored row is {\"name\":...,\"label\":...}.\n- CONTROL, the managed package item: GET /meta/app/setup reads lock: 'full', lockSource: 'package', editable: false, deletable: false.\n- On an earlier boot of the fix (1e6bf4fe48, the same authoring path):\n - a PUT on app/setup carrying protection answered 403 NOT_OVERRIDABLE, not this refusal;\n - a PUT of a protection block into a writable base row (?package=com.probe.base) answered 400.\n\n## Tests\n\npackages/metadata-protocol/src/protocol.save-door-protection.test.ts has 12 cases. It runs the real save door over a row-keeping engine stub, copied from the pinned package-unmanaged-install.test.ts double, with the dispatch predicates. Refusals are asserted as resolveThrownHttpError envelopes (status and code), never as a bare throw.\n\n- Probes (app, dashboard): 400 VALIDATION_ERROR, issues[0].path === 'protection', and zero sys_metadata writes.\n- Same refusal: draft mode, a malformed block (lock: 'sealed', a missing reason, null), the unmanaged import's face, and an overlay of a packaged dashboard that declares no lock.\n- Server-stated rewrites (source: 'migrate-stored', writeFace: 'package-duplicate'): the rewrite lands, the row carries no protection, and the caller's body is not mutated.\n- CONTROLS:\n - The same probe bodies without protection save, carry none, and stay editable and deletable.\n - A packaged dashboard, translated by applyProtection with protection: { lock: 'full' }, refuses an overlay save 403 ITEM_LOCKED, with or without a block in the body.\n - page, which does not declare the block, keeps the parse's 422 INVALID_METADATA.\n\nAblation, both legs, through scripts/ablation-replace.mjs from the committed state at edad2a33fd (protocol.ts blob 94ad6a645ede). The subject is imported from ./protocol.js, its source, so no dist was involved.\n\n- Leg A, the verbatim store (if (protectionRefusal) throw protectionRefusal; replaced, anchor 1 to 0, blob 94ad6a645ede to a685b721e5be): 6 failed, 6 passed.\n - Red: both probes, draft, malformed, the unmanaged face and the overlay. The probes resolved ("expected the call to be refused, but it resolved"), and the malformed case answered 422.\n - Green: the 2 probe CONTROLs, the 2 rewrite strips, the managed ITEM_LOCKED and page's 422.\n- Leg B, rewrites keep the block (request.item = withoutProtectionBlock(...) replaced, blob to 116fbe9f7340): 2 failed (the two rewrite strips), 10 passed.\n- Restore, after each leg: blob == HEAD (94ad6a645ede), and git diff HEAD is empty.\n\nPatch round 1, at 94c3c852b9 (a changeset sentence and a docblock only): pnpm --filter @objectstack/metadata-protocol typecheck exit 0, and package-unmanaged-install.test.ts + protocol.save-door-protection.test.ts 74/74.\n\nSuites at f8644fa685:\n\n- pnpm --filter @objectstack/metadata-protocol typecheck: exit 0. The new test is in the tsc program (--listFiles lists it once).\n- pnpm --filter @objectstack/metadata-protocol exec vitest run --maxWorkers=2: 229 files passed, 3 skipped; 28236 tests passed, 19 skipped.\n- pnpm --filter @objectstack/spec typecheck and pnpm --filter @objectstack/spec exec vitest run --maxWorkers=2: exit 0, 716 files, 20975 tests passed, 1 todo.\n\n## Gates, at 94c3c852b9 (patch round 1; first run at f8644fa685, same derivation)\n\n- node scripts/pm/dispatch-gates.mjs --commands on this diff derived 121 commands: the lead list's 80, plus the changeset, docs-reference and ledger families this diff adds.\n - All 121 exited 0, and so did pnpm --filter @objectstack/spec check:generated.\n - --ran reconciliation: "121 derived, 121 run, 0 NOT-MEASURED, 0 UNRUN", with every exit code recorded.\n - The changeset gates among them: check-changeset-no-major, check-adr-0087-registration (not-required (no-migration-prescription) accepted with the supersession sentence in the body) and check-empty-changeset, each exit 0.\n- check:engine-double-contract first asked the coverage ledger to learn the new pinned double: --write, +3 rows, all for the new file, 0 lost. check:docs asked for the regenerated reference page. Both are committed, and both gates are green at the head above.\n- Lint, a declared narrowing: pnpm exec eslint --no-inline-config --format json over the 18 changed .ts files gave 18 files, 0 errors, 0 warnings, and none of them is ignored by the config (isPathIgnored). eslint.config.mjs never enables type-aware linting (no parserOptions.project), so this diff cannot move any untouched file's verdict. The full pnpm lint is CI's.\n\n## Acceptance notes (observed, not fixed here)\n\n- Package export. On abf86554c9, a base row saved with protection was copied verbatim into GET /packages/com.probe.base/export's manifest. Measured: apps: [{ ..., protection: { lock: 'full', ... } }]. By code reading, the package loader translates such a block when that manifest is installed (registerApp, then registerItem, then applyProtection). With this change a base row can no longer carry the block, so a base author declares the lock in the manifest they install instead. No producer in this repo writes protection through the save door, and the clone doors already drop it. The changeset states this narrowing.\n- Stored rows. A row stored before this change keeps its bytes and is still served with its inert block until something rewrites it.\n- Flow clone. FLOW_CLONE_DROPPED_KEYS (runtime flow-clone.ts) does not list protection, while PERMISSION_SET_CLONE_DROPPED_KEYS does. Registry-hydrated flows are already stripped by applyProtection. A clone whose source body still carried a pre-change stored block would now be refused. Not measured.\n- Envelope choice. Triage asked for a 400. tenantAuthoredWriteRefusal uses INVALID_METADATA / 422 for a body carrying keys a client may not persist. This PR follows triage, with the VALIDATION_ERROR envelope of the door's other content refusals.\n\n---\n\n_Generated by Claude Code_\n",

✅ ACCEPT: PR #23115 at `94c3c852b9` · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-13T01:48Z

Basis:

triage 6133319631 binds the direction;
claim 6133589472;
report 6135259274, and patch round 1's report 6136167340;
the seat's note on this card.

Everything below was checked on GitHub, not taken from the reports. Classes, positions and functions only.

Form:
- draft to main, assignee os-steve;
- line 1 Fixes #23096, the only closing keyword;
- line 2 Clause-②: no (narrowing), the arm clause2-line.mjs requires for an accept-set narrowing. The seat wrote the PR body's evidence sections after round 1, as the role file assigns it.
Scope:
- 21 files, +570 / −49, none governed (check-governed-merges: clean);
- the regenerated content/docs/references/shared/protection.mdx and the pinned engine-double ledger rows are in;
- nothing under content/docs/releases/;
- the packages/spec TSDoc is cross-lane prose.
Fix, read in the diff (the refusal branch). ADR-0010 states one door for the block, the code package's loader (Phase 4.3), and says tenant org artifacts ignore L3 / L4 (§3.5). Accordingly:
- protectionBlockRefusal, called once in saveMetaItem after the authorization refusals, refuses a protection block with a located 400 VALIDATION_ERROR (issues[0].path is protection) on every type whose schema declares it, read through overlaySchemaDeclaredKey;
- server-stated rewrites (a source-stating re-save, and duplicatePackage) strip the block through withoutProtectionBlock instead of failing;
- applyProtection is not copied;
- the 15 mounts' TSDoc and the module docblock now say the loader translates and the save door refuses.
Evidence:
- on a showcase boot, the card's app and dashboard probes went from 200 with an inert lock to 400, with 0 rows stored;
- the CONTROLs hold: a body without the block is unchanged, and the managed app/setup still reads lock: 'full';
- 12 new cases;
- ablation legs A (the verbatim store) and B (the rewrites keep the block) each reddened only their own pins;
- the round-1 probe measured the supersession's three limbs through the real importUnmanagedPackage;
- 121 derived gate commands, all exit 0.
CI on 94c3c852b9: 41 check runs, none failed.
Contract review:
- FAIL 6135514431 on f8644fa685: the unreleased 15213-unmanaged-lock-strip changeset stated 422 for a malformed block;
- then delta PASS 6136290787 on 94c3c852b9. The delta is prose only. The supersession paragraph is true against the code and in the house form, and the docblock rider is done.
Findings:
- filed metadata save door: a hand-authored _lock binds on an environment item with no unlock door (any manage_metadata holder can brick an item); ADR-0010 §3.5 and the spec say the key is never authored; needs a ruling #23119, the raw _lock at the save door (triaged: pm:blocked on this card);
- filed runtime: FLOW_CLONE_DROPPED_KEYS omits protection, so cloning a flow whose stored row still carries a legacy block is refused 400 once the save door refuses the block (#23096) #23120, the flow clone keeps a legacy protection block. Landing this PR makes it reachable for legacy rows only, with a loud refusal.
Acceptance notes:
- two stale call-site comments in protocol.ts ("before every gate that reads or reshapes the body", and "only caller that states a source");
- the "beside a refused _lock" 400 limb is probe-measured, not pinned;
- stored rows that already carry an inert block are cleared only by a Studio round trip (migrateStoredMetadata records them as canonical).

Landing: prechecks pass:

every check is green;
merge-tree is clean against origin/main;
not governed;
619 lines.

The PR is readied and armed through the relay in this act.

Landed: PR #23115 → `e5f9f01607` · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-13T02:21Z

Merge: the merge queue merged PR fix(metadata-protocol)!: the save door refuses a protection block instead of storing a lock that binds nothing #23115 at 2026-10-13T02:19Z as e5f9f0160712a495be26782bfc9f8ea77b9aef55, with one parent, c8a9783eca. The ACCEPT is on this card, after the delta contract PASS 6136290787 on 94c3c852b9.
On main at that commit: the squash carries the accepted change exactly. All 21 files have hunks identical to the accepted head.
What main now holds:
- the metadata save door refuses a protection block with a located 400 VALIDATION_ERROR on every type whose schema declares the key, instead of storing a lock that binds nothing;
- the server-stated rewrites (a source-stating re-save and duplicatePackage) strip the block instead of failing;
- the 15 spec mounts' TSDoc says the loader translates the block and the save door refuses it.
Card: Fixes #23096 closed it as completed. In this act it drops pm:dispatched; the assignee stays as the record of who carried it.
Unlocks: metadata save door: a hand-authored _lock binds on an environment item with no unlock door (any manage_metadata holder can brick an item); ADR-0010 §3.5 and the spec say the key is never authored; needs a ruling #23119 (the raw _lock at the save door) carries Blocked-by: #23096 and is re-derived against e5f9f01607 next. runtime: FLOW_CLONE_DROPPED_KEYS omits protection, so cloning a flow whose stored row still carries a legacy block is refused 400 once the save door refuses the block (#23096) #23120 (the flow clone's legacy block) awaits triage.
