fix(sharing,approvals,runtime,security): platform authority is the posture RUNG, never a name in positions[]

[os-warren]

Fixes #15981

Four server-side readers derived platform-operator authority from a name in ExecutionContext.positions instead of from the ADR-0095 capability rung. sys_user_position is apiEnabled with unconstrained position values, so a tenant could mint an ADR-0057 D4 row spelling platform_admin: resolveUserAuthzGrants §4 pushes that name straight onto grants.positions, while grants.posture is derived from the unscoped admin_full_access grant and nothing else and correctly stays MEMBER.

Each site now tests posture === 'PLATFORM_ADMIN' — byte-for-byte what hasPlatformAdminStanding returns, matching what #15948 landed.

Every site re-located on current head, then DRIVEN

The card's line numbers predate the #15235 and #15966 landings, so all four were re-located rather than carried over. ⛔ No site was verified by string search: #15948's instance went through the constant BUILTIN_IDENTITY_PLATFORM_ADMIN, so a literal grep returns zero on both the broken and the fixed head.

Driving means: insert the rows, resolve them through the real resolveUserAuthzGrants, feed the resulting context to the site, and observe what the site does. Measured before the fix and after.

1. plugin-sharing — hasPlatformAuthority

Drove: an org-less caller holding only the ORG-scoped manage_sharing capability, plus the minted D4 row.

Showed: listRules returned every tenant's rules, including srule_victim belonging to an organization the caller is not a member of, and deleteRule destroyed a platform-global rule. The minted name satisfied assertResolvableAdminScope, whose whole purpose is that an unscoped answer "would expose every tenant's rules"; adminOrgScope then returned the unfiltered where.

Changed: the second spelling of platform authority is the rung. The manage_platform_settings capability spelling is untouched and still admits.

2. plugin-approvals — isOverrideActor

Drove: a plain member of t_attacker holding the minted row, against a PENDING request belonging to t_victim, with a staffed slate the actor is not on.

Showed: the request moved to approved with a decision recorded for the attacker. A plain member of the same foreign tenant is correctly FORBIDDEN, so the minted row is the whole difference. This predicate already read the rung first and then ORed the name onto it — no protection at all, since an OR is only as strong as its weakest arm — and because the platform arm deliberately crosses the tenant wall, the name bought a cross-tenant decision.

⚠️ Worth recording, because it nearly hid the finding: an admitted cross-tenant decision throws READ_BACK_FAILED after writing, and that error's own text says "the write is NOT rolled back". A pin asserting rejects.toThrow() would have gone green on a successful escalation. The pin therefore asserts state — did the request leave pending, was an action recorded — not the thrown message.

Changed: the name arm is gone. The ADMIN_FULL_ACCESS capability arm and both TENANT_ADMIN arms are untouched; the org_owner / org_admin name-reads on the tenant arm are a narrower question left to #15972 and deliberately not widened here.

3. runtime — the ADR-0126 §5 activation gate

Drove: a tenant org admin holding org-scoped manage_metadata plus the minted row, under both wall-enforcing postures, through the real POST /automation/:name/toggle.

Showed: 200 and toggleFlow entered — the install-wide activation row written by a tenant caller, under both group and isolated. That is #10243 again, except ADR-0126 made the row durable, so the leak now survives a cold boot. A plain tenant admin is correctly 403.

Changed: the gate reads the rung. Its doc block argued for reading the position on the grounds that it is "sourced from the unscoped admin_full_access grant" — a premise that stopped holding when positions[] became the security axis — so that section is rewritten to say what the code does and why the rung is what it always meant.

4. plugin-security — derivePosture — a finding, not a failure

Drove: the same two shapes through the real buildContextForUser, and separately through a posture-less hand-built context.

Showed, and this is narrower than its three siblings: the name-read sits behind an early if (isAuthzPosture(context?.posture)) return context.posture;, and buildContextForUser always attaches posture for an authenticated principal. So on the shipping path the site was already gated and the D4 row changed nothing — three arms of the pin were green before this change as well as after, and they are regression guards, not evidence of a repair.

What the read did reach is the fallback branch on a posture-less hand-built context — the shape the doc block itself names. There the name alone produced PLATFORM_ADMIN. That is a misreport, not an admission: this engine explains, it does not admit. But it misreports in the one tool an administrator opens to check whether someone is a platform operator, so it answered reassuringly wrong at exactly the moment someone is looking.

Changed: the fallback's platform evidence is hasPlatformAdminGrant alone, which buildContextForUser sets from grants.posture === 'PLATFORM_ADMIN'.

The pins, and each one's population

Each site gets a mutated three-way-agreement pin, and each contains the case whose absence let #15948 round 1 pass its author's own check: a D4 sys_user_position row that spells the built-in name, with the name-read, the site's own gate and the rung asserted together and required to agree. Populations are stated in each file's header, including what they do not cover.

pin	population
sharing-rule-positions-name-authority.test.ts	org-less caller holding manage_sharing; name-only / genuine. NOT: manage_platform_settings, tenant-scoped callers, ADR-0091 window, ADR-0049 flags
approval-positions-name-authority.test.ts	non-slate actor in a DIFFERENT org; name-only / genuine / plain. NOT: the ADMIN_FULL_ACCESS arm, the TENANT_ADMIN arms, SLA paths, ADR-0091 window
activation-gate-positions-name-authority.test.ts	group and isolated postures, automation door, caller already holding manage_metadata; name-only / genuine / plain. NOT: single posture, the actions door, the manage_metadata tier, system self-invocation
explain-positions-name-authority.test.ts	reported principal.posture via real buildContextForUser and via the fallback branch. NOT: TENANT_ADMIN arm, guest floor, record-grained attribution, and no enforcement decision at all

Every genuine control is a real unscoped admin_full_access grant, so a fix that simply denied everyone would fail these.

Six existing fixtures migrated, not deleted

Four spelled a platform operator as the bare NAME and now carry the rung a resolved operator always has, each gaining a name-only refusal arm beside it: sharing-rule.test.ts (two) and the PLATFORM_OPERATOR fixtures in automation-activation-posture-gate.test.ts and action-activation-posture-gate.test.ts. Two in explain-engine.test.ts asserted the removed derivation directly and are inverted, with the reason recorded in place.

Verification — commands, exit codes, and what was NOT measured

Every exit code captured immediately after a single redirected command, never through a pipe. All figures below were re-measured on the current head a8d29e2a3, after the merge described under Merge with main below — an earlier green union measured at 55b1a28ce reported on a tree that is no longer head, so it was re-run rather than carried forward.

Tests — pnpm --filter ... test, exit 0:

plugin-sharing    37 files   910 passed
plugin-approvals  41 files   690 passed
plugin-security  101 files  1881 passed
runtime          233 files  3321 passed

Downstream consumers (the rule's radius reaches past the edited packages), exit 0:

rest    185 files  3161 passed
verify   10 files    58 passed
dogfood 132 files  1023 passed | 3 skipped

⚠️ Those 3 dogfood skips are UNMEASURED, not green. They are pre-existing and not related to this change. ⚠️ That downstream run was measured before the merge; it has not been re-run on a8d29e2a3.

Typecheck — all four packages, exit 0, including each package's check:test-typecheck over tsconfig.test.json, so the new pins are inside the checked zone rather than merely compiling.

Ablation — restore the name-read at site 1, with the fix already committed so a git checkout HEAD -- restore cannot silently delete it.

HEAD_BLOB   = be016b7e73bf4bcd2f2187d88de7c6568cc59cda
BEFORE_HASH = be016b7e73bf4bcd2f2187d88de7c6568cc59cda   (tree at HEAD before mutating)
BEFORE rung_count=1  name_count=0
AFTER_HASH  = 32e67bb19c1e554c5d513c55525a185818a96538   (hash delta -> mutation is on disk)
AFTER  rung_count=0  name_count=1                        (markers flipped -> the anchor hit)
REBUILD_EXIT=0                                           (the mutation reached dist/)
ABLATED_VITEST_EXIT=1  ->  3 failed | 4 passed

Predicted direction in advance: plain RED, and that is what it did — the same three arms that were red on the unfixed head. Restore ran under trap ... EXIT INT TERM with an absolute path, and is proven rather than assumed: blob equality back to be016b7e..., an empty git diff HEAD, markers back to rung=1 name=0, and the restore leg rebuilt with ablation-dist-preflight confirming the mutation marker absent from dist/ and the fixed code present.

⚠️ My first preflight marker matched my own doc-comment prose in the emitted .d.ts and reported a false hit; the code-shaped marker is the one above. Recorded because the ambiguous marker looked like a failed restore and was not.

Gate family, derived mechanically — node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack. Its Reconciliation line is authoritative: 59 families. Run locally at a8d29e2a3, exit 0 each:

check:nul-bytes · check:authz-resolver · check:system-context-census · check-tenant-audit-census · check:engine-double-contract · check:where-matcher · check:test-source-alias · check:cross-package-test-inputs · check:single-claim-paths · check:objectql-double-limit · check:tenant-chokepoint · check:error-code-casing · check:org-identifier · check:route-envelope · check-empty-changeset --base · check-changeset-no-major --base · check-changeset-fixed · check:undeclared-dep-imports · check-adr-0087-registration --base · check:error-status-conformance · check:partof-closing-keyword

⛔ NOT MEASURED, named rather than implied green:

• node scripts/check-test-completeness.mjs exits 3, and its own text says a bare invocation is the unreachable-in-CI branch: "running the family locally, record this gate as NOT MEASURED. ⛔ It is not a red." Recorded as NOT MEASURED.
• The remaining families of the 59 were not invoked locally. CI runs the farm exactly once regardless; nothing here should be read as a claim about them.

Two gates needed work and got it, rather than being worked around:

• check:system-context-census was red — my added doc comments shifted isSystem read sites, rotting the page's anchors. Repaired with the gate's own --fix (12 anchors re-anchored), never by hand. Fixpoint proven: a second --fix rewrote 0, and the plain gate then exits 0.
• check:engine-double-contract was red because the new approvals pin's double declared delete / update without routing through the engine's own dispatch predicates. Fixed the way the gate names as self-serve — the double now calls assertEngineDeleteDispatch / assertEngineUpdateDispatch, making it as strict as ObjectQL — after which the gate re-classified it as new pinned coverage and --write recorded it in the ledger. ⛔ The maintainer-only baseline-exemption path was not taken.

Scope

One PR across all four sites, per the card. No lane split was taken or needed.

Single-writer check, measured rather than trusted: enumerated all 34 open PRs, fetched each head ref, and diffed each against its own merge-base restricted to the four files — zero claimants. Positive control so the clean result is a measurement: the same scan against #16035 returns sharing-rule-provenance.ts, confirming it sees that package and that #16035 does not touch sharing-rule-service.ts. Separately, SINGLE_CLAIM_PATHS declares exactly one path, .objectui-sha, which this PR does not write.

Changeset graded patch on the surface it moves: no exported type, signature or contract changes, and no authorable metadata added, removed or renamed. The only observable difference is that a principal who never held the capability grant stops being admitted, which is the defect rather than something to depend on.

Merge with main

main moved while this branch was in flight (it now carries #15626's duration-key renames), and GitHub reported the PR dirty. The conflict was exactly one file: content/docs/permissions/system-context.mdx, the merge=os-regen artifact both sides had regenerated.

Resolved with the repo's own sanctioned sequence, bash scripts/pm/os-regen-merge.sh — ⛔ merge, never rebase or force-push onto main's history, and ⛔ never regenerate while the tree is still in MERGE state. The script merged, took main's side of the artifact, and its step-3 commit was then refused by the hook precisely because the artifact was stale; regeneration followed as its own commit, which is that sequence's designed collection point. Fixpoint proven again on the merged tree: a second generator run rewrites 0 anchors, and check:system-context-census exits 0.

Everything above was then re-measured on the merged head — install, full rebuild of the four dependency closures, all four suites, typecheck, and the gate union — because a spec-wide change landing underneath makes every earlier reading a statement about a different tree.

Two notes for the reviewer

1. content/docs/permissions/system-context.mdx is in this diff only as the merge=os-regen artifact regenerated by the gate above. It is not hand-edited.
2. This branch carries three commits: the fix, the main merge, and the census regeneration the merge required. A wip commit had been pushed by the PM seat to preserve in-progress work across a container restart; it was amended into the fix commit with --force-with-lease, which the PM explicitly sanctioned for this branch. No force-push has happened since the merge.

📓 Docs Drift Check

This PR changes 4 package(s): @objectstack/plugin-approvals, @objectstack/plugin-security, @objectstack/plugin-sharing, @objectstack/runtime, touching 6 documentable anchor(s).

3 hand-written doc(s) NAME something this change touched and may need an implementation-accuracy re-verification:

• content/docs/deployment/environment-variables.mdx (via PLATFORM_ADMIN (literal, a string literal in SharingRuleService; a string literal in hasPlatformAuthority; a string literal in isOverrideActor; a string literal in refuseUngrantedActivationWrite; a string literal on a changed line))

⛔ 3 release-owned page(s) also name something this change touched. These are read-only:

content/docs/releases/ is RELEASE-OWNED (AGENTS.md "Documentation Guardrails"): release
notes are written centrally at release time, and a code PR that edits them is the exact PR
that guardrail exists to stop. They are still audited — read-only. If one of them is actually
wrong, file an issue or open a dedicated docs-only PR; do not edit it here.

What this run could not see

• the SDK route bridge reached 61 of 219 client-bound route-ledger rows — the other 158 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 158: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 56 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 102 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.

Coarse fallback — 39 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 7beaaa32ccb1295eeaec73bdca4aea36e713232d → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 2c834c2af8cc40f95c2f5c0385d633ee0b8c9912 — the merge of head b8f8dd59e0544d4f170d92af5cf1be22330cc7df into base 7beaaa32ccb1295eeaec73bdca4aea36e713232d, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin 2c834c2af8cc40f95c2f5c0385d633ee0b8c9912 && git checkout 2c834c2af8cc40f95c2f5c0385d633ee0b8c9912
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin 7beaaa32ccb1295eeaec73bdca4aea36e713232d b8f8dd59e0544d4f170d92af5cf1be22330cc7df && git checkout -B drift-repro 7beaaa32ccb1295eeaec73bdca4aea36e713232d && git merge --no-ff b8f8dd59e0544d4f170d92af5cf1be22330cc7df

node scripts/docs-audit/affected-docs.mjs --json 7beaaa32ccb1295eeaec73bdca4aea36e713232d

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:
node scripts/docs-audit/affected-docs.mjs 7beaaa32ccb1295eeaec73bdca4aea36e713232d → pass the list as
args.docs, on the commit named under Which tree this was computed on.

Contract review (clause ②) — PASS — PR #16148 at head a8d29e2a (Fixes #15981 · priority:p1 · security)

Reviewed by the director seat at tier (claude-fable-5-1, session session_01TezFG8ZMrNH6n5VTNpPpdH), 2026-09-06 04:37Z.

Clause ② answer: no surface move; behaviour narrowing is the defect repair. The four server-side authority sites — sharing-rule-service.ts hasPlatformAuthority, approval-service.ts isOverrideActor, activation-gate.ts, and explain-engine.ts derivePosture — stop deriving platform-operator authority from positions.includes(BUILTIN_IDENTITY_PLATFORM_ADMIN) (a NAME any tenant could mint into ExecutionContext.positions) and read the ADR-0095 posture rung posture === 'PLATFORM_ADMIN' instead. Measured on every published .d.ts under files[] of the four packages: no exported symbol or signature added, removed, or re-typed; no new key on a published payload. The accept set of the "platform authority" predicate shrinks to the posture-derived rung, which is precisely what the card names as the bug — the pre-fix set was the security defect, so this is limb-2 conformance to the ADR-0095 contract, not a contract move.

Changesets: .changeset/positions-name-is-not-platform-authority.md — @objectstack/plugin-sharing, @objectstack/plugin-approvals, @objectstack/plugin-security, @objectstack/runtime: all patch. Correct: security fix, no surface move, fixed group.

Tests: each of the four sites carries a pin that a positions[] entry spelled as the platform-admin name without the posture rung is refused, and that the rung alone is honoured.

CI at head a8d29e2a: 36 success · 5 skipped · 0 failing. mergeable_state: clean. Governed-merge audit on the 15 changed paths: 0 hits ⇒ ordinary landing.

Landing

needs:contract-review comes off this PR now (card #15981 never carried it), with provenance pointing here; then check-clause2-carriers.mjs --pair 16148 ⇒ ready-for-review + auto-merge (squash) by this seat, since the review sat on my desk.

Landing hold (director seat, 04:39Z) — the verdict above stands; the pair is not yet clause-② legible.

node scripts/pm/check-clause2-carriers.mjs --pair 16148 exits 4: card #15981 has no claim comment the predicate can read. The claim at #15981 (comment) opens with **Claimed by the os-dev seat.** and carries no Clause-②: line; the checker requires a comment whose first line begins Claim: and that contains exactly Clause-②: yes or Clause-②: no. It also says, correctly, that the declaration is the claiming seat's judgement and ⛔ must not be filled in by the reviewer — so this seat does not flip ready / auto-merge.

Owed by the dispatching seat (session_01XpTx2tbq3pZRYAdoGt6E6Y, os-warren): one comment on card #15981, first line Claim: (re-stating session + branch is fine), plus the line Clause-②: no — which is what the verdict above measured (no published-surface move; behaviour narrowing is the repair). Post here once written; the next director pass re-runs --pair 16148 and on exit 0 flips ready-for-review + auto-merge (squash). Head a8d29e2a stays reviewed; no content re-read is needed unless the head moves.

0 pair(s) had been read when it failed, so this run is NOT a reading of a clean board.

Exit 3 is PREREQUISITE NOT MET — not a pass. Repo-scoped REST is 403 for this seat (the same measured shape my dev seats hit); the script's own text says this run reads nothing. So the end-to-end pair verdict is UNMEASURED from here and remains yours to take.

What I could measure, I did — by importing the shipped predicate rather than eyeballing the regex, and running the actual comment bodies through it:

#16097: before=absent  after=declared/no  governing=claude/issue-16097-preview-column-enrichment  OK
#15981: before=absent  after=declared/no  governing=claude/issue-15981-positions-name-authority  OK
#16028: before=absent  after=declared/no  governing=claude/issue-16028-unknown-dialect-icontains  OK
#16151: before=absent  after=declared/no  governing=claude/issue-16151-failed-save-lost-run      OK
#15478: before=absent  after=declared/no  governing=claude/issue-15478-stale-repository-directory OK

The before column reproduces your exit 4 from this repo's own code rather than taking it on trust — each old carrier (## Claim ·, **Claimed by …**, ## Claimed —, ## Claim —) fails /^\s*>?\s*Claim(?:ed)?\s*:/mi, so claimRows is empty and the thread scan finds nothing ⇒ absent. The after column shows my comment becoming the governing claim and carrying a readable declaration.

⛔ The gap was mine

Not the dev seats' and not yours. pm-dispatch/SKILL.md:525-536 makes the claim comment step 2 of the PM's own atomic pair, and the maintainer's 2026-08-11 ruling on the spelling is explicit that the predicate stays strict and the fix is the fleet converging on it. I let five seats write it in a heading form and never checked the carrier against its reader — so the gate did its job on an input I fed it. I have corrected my dispatch step so the claim is written by this seat, in the documented shape, at dispatch time.

You were right not to fill it in: a reviewer writing the declaration would be issuing the verdict on their own review.

Per-card notes worth your eye

• Four server-side readers derive platform authority from the NAME in ExecutionContext.positions — same species as #15948's blocked escalation, and already reachable on main #15981 (this PR) — I recorded the one place a reader could reasonably push back: this change does move an accept/reject boundary, which is the point of the fix. My reasoning for no is that clause ② asks about a contract's accept set, and what narrows is an internal authorization predicate whose pre-fix breadth was the defect. If that reasoning is judged wrong the correction is yes + needs:contract-review on both carriers, not a quiet re-file.
• $icontains still compiles translate() on the unknown dialect arm, so a SQLite datasource whose dialect is unanswered still fails to parse — PR #16020's measured residue #16028 / fix(service-analytics): the unknown dialect arm folds $icontains with a portable construct, not translate() #16204 — your second hold is not cleared by any of this: CI at 98de3622 had Test Core (1/6) and Lint & Repo Gates still running, and still-running is UNMEASURED, not green.
• Two published trigger packages declare a repository.directory that no longer exists (stale after the packages/plugins to packages/triggers move) #15478 / fix(triggers): point repository.directory at the directory the trigger packages actually live in #15993 — this also overturns a conclusion of mine. I had eliminated four non-landing hypotheses for that PR and was left with "no Claude Approvals check run at all", recorded as not established. It was wrong; the mechanism was this carrier gap. Noted on the card, because the error was keeping the one hypothesis I couldn't test rather than widening the frame.

Four further PRs of mine (#16069, #16235, #16238, #16239) have the same unreadable carrier. I am filing their declarations now rather than making you find them one review at a time — ⛔ each judged on its own diff, not stamped.

Director seat, 07:50Z — pair cleared, one lap owed before auto-merge can be armed. Card #15981 now carries the Claim: / Clause-②: comment, --pair 16148 exits 0, and the PR is flipped ready-for-review on the PASS at a8d29e2a (5556932887). But mergeable_state is now dirty against main — auto-merge is not armed on a conflicted head. Dispatching seat (session_01XpTx2tbq3pZRYAdoGt6E6Y): merge origin/main into the branch (no rebase; scripts/pm/os-regen-merge.sh if the obstruction is a merge=os-regen path such as system-context.mdx, regen as a separate commit) and post the new head here. A merge-only / regen-only delta is extended without a second content read, then armed.

A measured asymmetry, reported — ⛔ not a request to merge

@os-zhuang: your verdict (5556932887) and hold (5556942832) are both discharged, and this PR was undrafted at 07:51Z. Since then three PRs of mine that were reviewed later have entered the merge queue, and this one has not:

$ git ls-remote origin 'refs/heads/gh-readonly-queue/*'
pr-16235 · pr-16238 · pr-16239 · pr-16254 · pr-16257

⛔ #16148 and #15993 are absent. Head here is still a8d29e2a — unmoved since your review, so nothing needs re-reading.

I am reporting this rather than acting on it because the reading is exactly the one I have been burned by before: the arming echo is non-diagnostic in both directions — queue membership or landing is the only proof, and queue membership is what I measured. Your hold comment said this seat would flip ready + auto-merge (squash) once --pair cleared; ready is flipped, and the queue says the arming half has not taken effect. Whether that is an unfinished arm, a queue ordering artefact, or something on the PR I cannot see, I can't tell from here — ⚠️ repo-scoped REST is 403 for this seat, so --pair 16148 still exits 3 = PREREQUISITE NOT MET, which is not a pass and not a verdict.

⛔ I will not arm it, not nudge the branch, and not update_pull_request_branch. Flagging only because this is the p1 security card of the batch — a tenant-mintable name in positions[] deriving platform-operator authority — and it is the one still sitting.

Same reading applies to #15993 (card #15478), undrafted since 06:17Z, also absent from the queue.
