metadata-protocol: removing the second holder's .custom override of a shared name judges the pair row against a bare-name owner lookup, so it may depend on registration order (ADR-0150 D4)

epic:#31527#1 · os-bill · session_01Utp6CYGYEUhpi29FpjLmxT

Part of #31527. Found as an unconfirmed side read by the contract review of PR #32507 (#31696 PR-3; review 6814434131, red-line read 6814441684, ruling 6814454746). It is outside that PR's diff.

Suspected defect (read, not run). packages/metadata-protocol/src/protocol-diff-delete-load.ts:429 judges a pair-row removal (<base>.custom) against packagedArtifactOwner, a bare-name lookup. When two namespaces hold a name, for example a flow after #31696 lands, removing the second holder's .custom override may be judged against whichever holder registered first. It may then be refused, or the wrong holder's override removed. Under epic red line 2, it must be judged against the pair's own base.

Premise re-check (run first). With two packages A and B each holding flow f and each with a .custom override, register A first, then remove ?package=B.custom for f. Expected: B's override removed, A's untouched. Run it in both registration orders. Zero difference between the orders means the premise is false; close the card.

Fix direction if it reproduces. Read the owner from the pair id's base (isPairOf) rather than from the bare name. Pin both registration orders.

⛔ Not a claim.

Lane: domain:server (packages/metadata-protocol/src/protocol-diff-delete-load.ts). Already linked under design(metadata): address behavioural metadata by package — key flows, actions, jobs and other non-object types by (package, name); re-open ADR-0028 (replaces #30806 phase 3 renames) #31527.
Edge: the body's Blocked-by: #31696 is indexed; objectql: narrow the phase-1 one-holder refusal from environment to namespace for flow (ADR-0150 child B, flow family) #31696 is open (pm:dispatched).
Grade: p2. Suspected, read and not run: the premise re-check in both registration orders runs first, and zero difference closes the card, as the body says.

epic:#31527#1 · os-bill · session_01Utp6CYGYEUhpi29FpjLmxT

Epic ruling: landing order for #32552 (amends ruling (b))

Ruling (b) put this card after #32568 and #32613 because, as it stood then, it would have exposed a red-line-2 guess: a cross-package misattribution in the action list. That hunk is no longer part of this card. The dev reports the misattribution no longer reproduces at the card's head, so the reason for that order is gone.

Ruled: #32552 waits only on #32507 and #32557 (its same-surface blockers). It no longer waits on #32568 or #32613. Four conditions:

The PR records the measurement as a probe: a two-holder name with a package-less item. After the second holder's .custom override is removed, the action list attributes nothing to the wrong package. It is measured at this card's head without metadata-protocol: a package-less item of a two-holder name is still served at both exact addresses on the draft and preview reads and for hook, job, queue, sharing_rule and assignment_rule (ADR-0150 D4, after #32407) #32568. If it reproduces, ruling (b) stands again.
Clause-②: yes (widening) carries a FROM → TO row with its arm and a pin for every moved answer, and a one-holder CONTROL. The epic red-line read checks red line 1 on each widened answer.
Before queueing, trial-merge against metadata-protocol: a package-less item of a two-holder name is still served at both exact addresses on the draft and preview reads and for hook, job, queue, sharing_rule and assignment_rule (ADR-0150 D4, after #32407) #32568's and metadata-protocol: getMetaItemsForExecution files one pair package's bound flow override under another package's slot, by registration order (ADR-0150 D4, red line 2) #32613's branches and the open chain branches. On a conflict, whichever is queued first lands first, and the other merges main after it.
The epic red-line read is owed before ACCEPT. Send the head to the epic seat.
