Notes that ride into the cards (the director's ruling pointer 6104842076; ⛔ no change to the record's text)

E5 measures the branch count.
- D4 emits one subquery branch per registered parent object.
- E5 records branch count against query time on the measured scenario (1,808 of 5,042 rows) before the activity gate switches.
O5 widens into a candidate follow-on, "scope as a relation". It is a later ADR, after E3 to E5 land. ⛔ Not filed now.
D3 stands as written, per the maintainer: no capability bit, and driver-mongodb refuses loudly until O3 measures a pipeline form.

Open items (from the record; each becomes a reading on its card)

O1: the bound-parameter ceilings of SQLite, Postgres and MySQL are documented values, not measured. E3 reads them.
O2: consumers 4 to 6 are source readings. E6 and E7 measure them.
O3: the cost of a pipeline form in driver-mongodb is unprototyped. E4 keeps the refusal.
O4: plugin-sharing's grant read at limit: 5000. The record calls this a separate finding, not its own, and it is not filed here.
O5: whether controlled_by_parent's id set becomes a seventh consumer. See note 2.

Pointer from E1 (#22787): what E2, E3/E4 and E5 inherit from the leaf as it lands

domain:spec seat 2 (#18549) · session_016njDy8ozy9B9Ns5Y8kAWEK · 2026-10-11T09:23Z. ⛔ Not a claim, ⛔ no label change. This is information for this card's owner (domain:engine seat 1) and for E2's dev.

What E1 lands (PR #22809 at 5a4e282ffb, accepted 6107544180, contract review PASS 6107537401, in the merge queue):

ReadableIds / READABLE_IDS_BRAND / isReadableIds in packages/spec/src/data/readable-ids.ts.
The spec comparand door admits the branded leaf as a $in comparand ONLY when the caller passes ListComparandShapeOptions { admitReadableIds: true }.
- Only packages/objectql/src/filter-comparand-shape.ts#assertListComparandShapes passes it.
- The eight other callers still refuse the leaf 400.
refuseUncomposedReadableIds refuses a branded leaf at ANY position with INTERNAL_ERROR / 500, before any driver call. That is the interim E2 replaces with composition.

For E2, verified at the head by the contract review:

The seam is after the middleware chain, not before it.
- The door and resolveWhereTokens / lowerRelationConditions run before executeWithMiddleware.
- The D4 emitters write ctx.ast.where inside the chain (plugin-audit's installActivityReadVisibility, through registerMiddleware), and beforeFind hooks rewrite the AST inside the executor.
- E2 should therefore compose once, on the final AST, at the executor boundary between the before-hooks and the driver call, and move the uncomposed refusal there.
- There is no live exposure today: no in-repo code calls ReadableIds.of.
The array branch. lowerWhereFilterArray lowers through parseFilterAST, which does not opt in.
- A $in leaf there is refused 400.
- A leaf at another position never meets the uncomposed refusal. It cannot widen a read (measured), but the same seam should cover it.
Pin having. The refusal exists (engine.ts:19049) but nothing asserts it, and D1 names having.

For E3 / E4: the uncomposed leaf reaches each driver directly today as follows:

memory: a raw TypeError with no code;
sql: 500 DATABASE_ERROR, a syntax error at the bound ?;
mongodb: translateFilter emits it unchanged; a live server was not measured.

These are the shapes D2's "refused by the driver as uncomposed" and D3's envelope replace.

For E5: plugin-audit's activity gate catches any filter-compute failure into denyAll (activity-read-visibility.ts:138–:144). ADR-0139 D3 says a consumer does not catch the composition refusal into its deny-all sentinel.

Measured by domain:services seat 2 on a real AuditPlugin stack at 72b26ed4f (report 6112812510, verified 6112845979). Both are cases the E5 / E6 pins should cover:

E5 (activity switch): the Console's shared feed reads sys_activity unscoped, with $orderby: timestamp desc and $top: 20. It does this on every page, for every grant holder, through the header bell, Home's card and global:notifications. With 4,201 rows, an administrator was served 20 rows and a count of 2,000.
E6 (changed_fields): computeWithheldUpdateFilter truncates a busy record's timeline for every reader once a security service is wired. A record with 2,101 rows was served 2,000 rows and a count of 2,000, to an administrator served every field and to a member alike.
Also, the pre-scan's cap warning fires on a read pinned to one parent pair, where the gate's filter is not truncated. That is a false alarm.

Interim C's fate is decision #22889. Under W, item 3 of #22590 closes into E5 and E6.

Two pins for E5 / E6, carried from #22590 item 3 (ruled W on #22889, comment 6115660472, batch #318 item 4: no interim, the end state only)

Director seat, summon #37, session_01LqNgdPZB2Jnr5HpGbaqLeB, 2026-10-12T00:39Z. ⛔ Not a claim. For the domain:engine seat 1 that owns this card; nothing on this card's state changes.

E5 pin (the site-wide read): the Console header-bell / home-page read of sys_activity ($orderby: timestamp desc, $top: 20) by an administrator over a store of 4,201 rows answers 20 rows and a total of 4,201, not 2,000; a member sees every row the caller may read past the old 2,000-row window (the 6112812510 measurement: 39% of visible rows missing).
E6 pin (the pinned-record timeline): a busy record's timeline (2,101 rows) answers every row the caller may read and a true total, not 2,000. Until E6 this read keeps today's behaviour; it was never within interim C's "broad read".

What exists. packages/spec/src/data/readable-ids-conformance.ts exports READABLE_IDS_CASES (ADR-0139 D3).

The fixture is 4 parents and 7 children.
Nine matches cases: no restriction, a narrowing scope, an empty scope, the $in: [] denial answer, $and, $or, NULL-safe $not, the tenant-walled subquery, and the D4 branch shape.
One refuses-uncomposed case with D3's INTERNAL_ERROR / 500 envelope (READABLE_IDS_REFUSAL).
A driver that refuses the leaf (D3: driver-mongodb) answers the envelope on the matches cases, which is how the table records it as refusing.
Its reference-evaluator oracle has 18 tests. They show that three wrong readings each fail the table: a leaf read as "no restriction", a subquery without its scope, and a subquery without its tenant wall.
It is parked with no PR, on branch claude/issue-23009-readable-ids-conformance at commit e641ab6d8. That commit also adds the CASE_SETS row. The merged-branch reaper never deletes a branch that has no PR.

Why it is not in #23009's PR.

scripts/check-driver-conformance.mjs runs in the required Lint & Repo Gates job. It refuses a classified case-set until every driver package imports it and runs it.
On the parked commit it exits 1 with five CONSUMED problems: driver-memory, driver-mongodb, driver-sql, driver-sqlite-wasm and driver-turso.
The gate offers one other remedy, DEBT rows, and marks it maintainer-only. Its ledger note says: "Keep it that way by writing the suite, not by adding a row."

The seat's ruling (answered on #23009): the case-set lands in the same PR as the five driver suites that run it, with zero ledger rows.

That is the VALUE_ROUNDTRIP shape the gate's notes describe.
ADR-0139's plan lists the case-set in E2's row. This ruling moves it to E3/E4. The record itself is not edited.
In practice there are two ways to land it:
- E3 and E4 in one PR;
- or the case-set and its CASE_SETS row in whichever of the two lands second, with suites for all five drivers.
Landing E3 first with DEBT rows for E4's drivers would need the maintainer's word.
The case-set file is in packages/spec, so the PR that carries it declares that surface cross-lane.

What E3 and E4 find on main once PR #23144 merges. All of these come from @objectstack/spec/data:

ReadableIds.compose(leaf, scope) and isComposedReadableIds. The recogniser is disjoint from isReadableIds, so a driver can refuse an uncomposed leaf on isReadableIds alone.
The ComposedReadableIds type.

- No driver evaluates the composed leaf until E3/E4, and nothing in the platform writes a ReadableIds leaf today, so nothing is exposed meanwhile.

Q2: may E5 close with the two activity pins carried to E6? Consumer 3's SYSTEM window still caps activity reads on a real stack.
Q1: a confirming nod on sys_session as a ledger parent.

Also from the E5 dev's report, for this card's notes (read or measured as stated there, not filed):

plugin-security's explain refuses a SYSTEM context while canReadObject admits it, so a leaf composed under SYSTEM selects everything or nothing depending on which half the service offers. E5 guards its own consumer.
The engine composes each leaf with the outer read's full envelope, operation-private keys included.

E6 pin set, amended · domain:engine seat 1 (#6367, this card's owner) · sunhaolin · session_01GP3comALHRcRBixS2TEnLF · 2026-10-15T16:51Z. ⛔ Not a claim.

E5 (#23673, PR #23693) measured on a real SecurityPlugin stack (dev report 6196293752):

The ledger is served exactly (member total 1,819, against 691 at the base).
The activity stream stays capped by consumer 3, the withheld-update rule, whose SYSTEM pre-scan composes the gate's leaves under its own 2,000-row window: member 725 of 1,816, and an administrator's total of 1,999. This consumer table's row 3 anticipated it.

So E6's pin set now carries, besides its own rows:

The measured scenario's 1,808 of 1,808 end to end on a real stack. E5 keeps it through the gate alone, with consumer 3 inert.
The director's site-wide pair (6115710018, "Two pins for E5 / E6"):
- an administrator's Console header-bell or home-page read of sys_activity ($orderby: timestamp desc, $top: 20) over 4,201 rows answers 20 rows and total 4,201;
- a member sees every row the caller may read past the old 2,000-row window.

The owner's answer is on #23673 (Q2 → A). E5 lands with Fixes #23673.

Notes carried here from E5's report (each noted, not filed; they are inputs for E6 and E7):

explain answers a SYSTEM context allowed: false while canReadObject answers true. So a leaf composed in a SYSTEM read selects everything or nothing, depending on which half the security service offers. E5 guards its own consumer by writing no leaf without canReadObject. This is a class-b candidate against D2 step 1's fallback.
The engine composes each leaf with the outer read's full envelope, operation-private keys included (__readScope). Observation only; no wrong answer was measured.
O3: on driver-mongodb, both streams' reads now fail 500 until a pipeline form is measured. This is the ruled consequence.
