   Claim: PM loop round 17 · 2026-10-20T16:08Z · p2, domain:engine (triage's grade), filed by domain:services seat 1 from #24775's dev report; it blocks PR #24885. The authorization prelude reads sys_user_permission_set with no projection, so every formula field on it is computed in every request's prelude. PR #24885's one-hop display_title would add a sys_user read and a round trip for each principal holding a direct grant.
   Session: session_01JtSQQ3EWsbNPzyYMug1tXy (the dispatching seat; the dev runs as its own cloud session, named in the dispatch comment)
   Account: os-project-manager (the seat's linked user as GET /user answers it; always the card's assignee)
   Branch: claude/issue-24896-prelude-grant-projection
   Worktree: objectstack-issue-24896
   Domain: domain:engine
   Seat: domain:engine#1 (seat post #6367)
   File surface:

   • Measured first:
     • every column of a sys_user_permission_set row that the prelude reads, through isGrantActive, grantSetNameOf, grantOrganizationOf, nextGrantValidityBoundary and every other consumer of upsRowsAll / upsRows;
     • whether a fields projection on ql.find stops objectql computing a formula field the projection does not name (objectql: a formula field in a fields projection widens it to every column and the rows are never trimmed back — get_record sends owner, org and audit columns to an external endpoint #22300: a formula field IN a projection widens it);
     • the read and round-trip counts for a grant holder, before and after, on the rig of plugin-auth's auth-prelude-query-count.pin.test.ts, with PR fix(plugin-security): a permission-set assignment is titled by the person's name, not the raw user id #24885's formula applied locally.
   • packages/core/src/security/resolve-authz-context.ts: the prelude's sys_user_permission_set read projects exactly the columns measured, through the module-private tryFind.
   • Pins:
     • the resolved authz context of a grant holder is identical with and without the projection: an active grant, an expired one, an organization-scoped one, a deployment-wide one, and an admin_full_access grant;
     • auth-prelude-query-count.pin.test.ts gains a grant-holder case, whose read and round-trip counts do not move under a display formula on sys_user_permission_set.
   • The changeset: patch for @objectstack/core.

   ⛔ Not in scope:

   • PR fix(plugin-security): a permission-set assignment is titled by the person's name, not the raw user id #24885's formula (domain:services');
   • the prelude's other reads (sys_member, sys_user_position): measured and named in the report if they carry the same cost, not built;
   • the grants cache's default.

   Cross-lane: auth-prelude-query-count.pin.test.ts is in packages/plugins/plugin-auth, which is domain:services'. That lane's seat 1 filed the card and names the pin in its "Done when"; the seat declares the test edit to it before the queue.
   Container & model: M, mode:cloud (one projection on a security read, an equivalence pin across grant states, and a query-count pin), model: TIER_DEFAULT (this run's dispatch-gates.mjs --tier: "no path-derived mandate")
   Clause-②: no (a read's projection: every resolved authz answer is unchanged and pinned so; no accept set, served shape or export moves)
   Responsibility: every request by a principal holding a direct permission-set grant pays for formula fields its authorization never reads, and PR #24885 would add a read and a round trip to that | the prelude's grant read names no projection | every principal with a direct grant (organization and platform administrators among them), on every request
   Thread-read: none
   Serial constraints cleared: open PRs' file lists and the pm:dispatched claims were read at this claim.

   • No open PR touches resolve-authz-context.ts or auth-prelude-query-count.pin.test.ts.
   • PR fix(plugin-security): a permission-set assignment is titled by the person's name, not the raw user id #24885 (domain:services) edits sys-user-permission-set.object.ts and its own test; it waits on this card, and merges main after it lands.

   Dispatch · domain:engine seat 1 · session_01JtSQQ3EWsbNPzyYMug1tXy · 2026-10-20T16:10Z: mode:cloud. The dev session is session_01BQSBMNgcScNf9TzF8W6YpU. It builds at the default tier on branch claude/issue-24896-prelude-grant-projection, under claim 6295406119.

   • Read first:
     • every column of a grant row the prelude reads, each with the line that reads it;
     • whether an objectql fields projection stops a formula the projection does not name, and its lookup hop;
     • a grant holder's reads and round trips on main, with PR fix(plugin-security): a permission-set assignment is titled by the person's name, not the raw user id #24885's formula applied locally, and with the projection plus that formula.
   • What lands:
     • the prelude's sys_user_permission_set read projects exactly those columns, through the module-private tryFind;
     • an equivalence pin: a grant holder's whole resolved authz context is identical with and without the projection, across active, expired, organization-scoped, deployment-wide and admin_full_access grants;
     • a grant-holder case in plugin-auth's auth-prelude-query-count.pin.test.ts, whose counts a one-hop display formula cannot move;
     • an ablation and a patch changeset for @objectstack/core.
   • Not built: PR fix(plugin-security): a permission-set assignment is titled by the person's name, not the raw user id #24885's formula, the prelude's other reads (measured and named if they carry the same cost), the grants cache default, and any change to what the prelude resolves.
   • Cross-lane: the query-count pin is in plugin-auth, domain:services' package. The seat declares the test edit to that lane before the queue.
   • Owed: the seat's review of record before the queue.

   "premise_still_valid": true,
   "summary": "Premise confirmed on main 74fcec1: the prelude's sys_user_permission_set read named no projection. With PR #24885's one-hop title in the test fixture, a grant holder measured 9 reads / 5 round trips, against 8 / 4 with the declared title. The read now projects exactly permission_set, organization_id, valid_from and valid_until, through the module-private tryFind (new optional fields parameter, no export). Under the one-hop title the grant holder stays at 8 / 4. Column list measured before the edit: permission_set via grantSetNameOf (anchorReadsDefaultOrganization, mayApply, ledger names, anchorsPlatformStanding, 6b set loop); organization_id (helper also accepts organizationId) via grantOrganizationOf (grantAppliesInTenant, grantAnchorsPlatformStanding, mayApply, applyingGrants); valid_from and valid_until (helpers also accept validFrom/validUntil) via isGrantActive (upsRows filter) and nextGrantValidityBoundary (grants-cache boundary over upsRowsAll). Nothing reads id, user_id (it is only the filter), granted_by, reason or display_title. objectql: planFormulaProjection evaluates only the formulas a non-empty fields list names, so a list of stored columns computes no formula and issues no hop. Per #22300, the widening happens only when a formula is IN the projection. No id or system column needs naming: driver-sql returns only the named columns and the resolver reads no id. sys_member and sys_user_position are also unprojected, but their display_title formulas read only own columns, so today they cost CEL per row and no read. Named, not built.",

(2) New pin packages/core/src/security/resolve-authz-context.grant-projection.test.ts: 25 tests pass. Twelve grant-state fixtures (active in tenant, other org, expired, not yet valid, in window, org-null with and without tenant, Default-Org admin_full_access acting elsewhere and with no tenant, expired admin_full_access, other org's admin_full_access, all states at once) plus the 11 batch-equivalence FIXTURES. Each resolves the identical whole envelope over projected rows (named columns only, no id) and over full rows plus a computed title. Further cases pin the four-column projection, that no other read is projected, and that the fixtures discriminate (at least 5 distinct envelopes, 3 PLATFORM_ADMIN). (3) Count pin: new describe.each grant-holder case under the declared and the one-hop title, 7/7 pass on projected core. (4) Ablation, projection reverted via ablation-replace --hold with marker ABLATION_24896: preflight saw the marker in core dist index.js and index.cjs. Count pin red only on the one-hop case (sys_user 3, expected 2: 1 failed, 6 passed). Equivalence pin red on the projection case (1 failed, 24 passed). Restore: blob 6d3b1baf7150 == HEAD and git diff HEAD empty; after the rebuild, preflight --absent found the marker absent from all 14 built files and the tree clean. (5) Column sweep, each column dropped in turn: permission_set 11 failed, organization_id 11, valid_from 3, valid_until 6, envelope fixtures failing each time, every leg restored blob == HEAD.

   What main now holds:

   • The authorization prelude's grant read names its columns. Every authenticated request reads the principal's sys_user_permission_set grants, and that read now asks for exactly the four columns the resolver decides on: permission_set, organization_id, valid_from and valid_until. No formula field of the grant table, its record title included, is computed there.
   • A grant holder's prelude stays at 8 reads in 4 round trips, whatever display formula the grant table declares. A title that reads one hop through user_id would otherwise have cost each such request one more sys_user read and one more round trip.
   • Unchanged: the resolved authorization context, for every grant state (active, expired, not yet valid, organization-owned, deployment-wide, and the Default Organization's admin_full_access grant). It is pinned whole, and each of the four columns is shown load-bearing. The prelude's other reads are untouched.
   • Shipped as: patch of @objectstack/core.

   Unblocked: PR #24885 (domain:services) can land its one-hop display_title without adding a read to the prelude. plugin-auth's auth-prelude-query-count.pin.test.ts now holds a grant-holder case under that title, declared to that lane at 6296470031. #24885 merges main first.
