Batch resolveUserAuthzGrants: 8 sequential round trips could be 2-3, with no caching and no staleness

Split out of #10757 (direction 4) by PM ruling on PR #10824.

resolveUserAuthzGrants (packages/core/src/security/resolve-authz-context.ts ~330–560) issues 8 sequential round trips — legs 6–13 of an authenticated data request:

6.  sys_member {user_id}
7.  sys_user_position
8.  sys_member {organization_id}          (fellow-org, limit 1000)
9.  sys_user_permission_set
10. sys_position {name $in}
11. sys_position_permission_set
12. sys_permission_set {id $in}
13. sys_user {id}                          (ai_seat)

They could be 2–3. No caching, no invalidation contract, no staleness — every read stays live, so this is independent of #10757's tranche 2 (caching) and cannot drift from whatever invalidation design that lands.

Why this is likely the highest-leverage no-risk work left

cloud#1539 measured, causally by latency injection (R² = 0.9994), that an authenticated request is 23.4 sequential legs and that:

L, not N, is the multiplier. Batching is worth exactly as much as deleting.

So collapsing 8 legs into 2–3 removes ~5–6 of 23.4 — roughly a quarter of the whole request — without touching a single authorization semantic.

Against the measured prod model server_ms ≈ 33 + L × 36.6:

	legs	prod server time
today	23.4	~890 ms
after this card	~18	~690 ms

Not sufficient alone (cloud#1521's gate is ≤200 ms, and placement is the lever that clears it — cloud#1546 is testing that now), but it is the largest block available that carries no staleness risk whatsoever.

Why batching beats caching here, stated plainly

A batched read returns the same rows or fails loudly. A cache returns stale grants silently — a permission revoked at T still honoured until a TTL expires. On the authorization path that difference is the whole ballgame, which is why this is separable from tranche 2 and worth doing whether or not tranche 2 ever ships.

Constraints

Do not change authorization semantics. A batched query must return exactly the rows the sequential reads returned — same filters, same tenancy scoping, same ordering guarantees where any are relied on. Prove equivalence rather than asserting it; this is the one way this card could ship a security bug behind a green suite.
No caching. Nothing may survive a request. That is tranche 2, and it is deliberately a different card with a different review.
packages/spec is off limits — stop and report if a batch needs a contract change.
Legs 9 and 13 duplicate reads made earlier in the request (see Authenticated data requests issue ~20 DB queries in ~17 sequential legs — per-request auth/session/localization/metadata resolution has no cross-request caching, costing ~1.5s/request on remote Postgres #10757). They are not free to remove here — PR perf(security,protocol): stop asking the same question twice within one request #10824 measured that the removable half of each pair belongs to directions 1 and 2. Batch them; do not delete them.

Measuring the result

X-OS-Debug-Timing: json on an admin principal returns Server-Timing: db;dur=…;desc="N queries". That gives the query count directly, but the number that matters here is legs, not queries — report both, and say how you established the leg count (a batch that runs 3 queries in parallel is 1 leg; 3 sequential is 3).

Triage: + domain:engine — resolveUserAuthzGrants is packages/core/src/security/resolve-authz-context.ts (engine by the lane table). Queue state set by the splitting PM ruling (PR #10824); type Task. Dispatch notes for the engine seat: the card's own constraints are the dispatch clauses (no caching, prove row-equivalence rather than assert it, packages/spec off limits, legs 9/13 batched not deleted); shares a file family with #10826 — answer fold-or-serial for the pair (see the note there). This is the highest-leverage no-risk perf item currently queued (~¼ of measured request latency), worth early scheduling.

  "legs_before_after": "measured: 8 -> 4. Three independent methods, none inferred from the query count. (1) Latency injection, cloud#1539's own method applied to this function: every read costs a fixed D ms, so wall/D is the leg count. D=50: 412ms -> 206ms; D=25: 230ms -> 106ms; both runs resolve an IDENTICAL grants envelope. (2) A leg-counting engine double in the suite -- each read yields on a real macrotask boundary, a read starting with nothing in flight opens a leg, one starting while another is in flight joins it; asserted per fixture (BATCHED_LEGS) across 11 shapes: 4 for the richest principals, 3 with no active sys_position row, 2 with no permission sets. (3) The await graph: 4 await points on the longest path. NOT measurable as latency on a local rig -- better-sqlite3 is synchronous and in-process, so there is no round trip to save; that is why cloud#1539 injected latency instead of reading a trace. Four is the floor: sys_position -> sys_position_permission_set -> sys_permission_set is a real chain (names, then ids, then the union of set ids); collapsing it needs a join/traversal that the generic `ql: any` seam cannot guarantee across engines, which is a contract change this card is fenced out of.",

Two independent goldens per fixture: (a) the whole resolved envelope, deep-equal INCLUDING array order -- positions, permissions, systemPermissions, org_user_ids, accessible_org_ids, tabPermissions, posture, email; (b) the exact multiset of {object, where, limit} triples issued, each with context.isSystem === true, plus query-count equality -- the 'same filters, same tenancy scoping, same limits' half. Multiset rather than sequence because parallelising IS a change of issue order. The double ENFORCES the caller's limit like a real driver, so a moved limit is observable. Shapes: empty / multi-org / lapsed-own-membership-among-active-peers / position-derived / permission-set-derived / tenant-admin-via-position / ai-seat-and-email / ai-seat-denied / seeded-permissions-and-email / read-limits-truncate / no-active-org, spanning MEMBER-TENANT_ADMIN-PLATFORM_ADMIN, ADR-0091 windows, ADR-0049 deactivated positions and sets, org-scoped vs unscoped. DIVERGENCE CASE requested by the ruling: the two sys_member reads now sit in the same wave, so the obvious next 'improvement' is one $or read partitioned in memory -- on `lapsed-own-membership-among-active-peers` that is a silent escalation (the caller's own membership in org_a has lapsed while peers hold active owner/admin rows; a merged read feeds those peer rows to the accessible_org_ids loop and the org-role loop, granting org_a and org_owner/TENANT_ADMIN). The golden pins the sequential answer: accessible_org_ids [], no org_owner, posture MEMBER, peers still in org_user_ids. read-limits-truncate covers the limit hazard (205 own memberships vs limit 200, 1005 peers vs limit 1000, truncation observable). LIVE: GET /api/v1/auth/me/permissions, 12169 bytes, byte-identical before/after with ids normalised -- real ObjectQL engine, real SQL driver, so $in translations and tenancy predicates are checked as compiled SQL, not only against a double.",

Parallelising is the ONLY change: no read's object, where, tenancy scoping or limit moved, no caching, nothing survives a request, and legs 9 and 13 are batched rather than deleted. The two sys_member reads are deliberately NOT merged -- the test file carries the fixture where merging is a silent privilege escalation. Note one discrepancy for the PM: my dispatch prompt named the branch claude/issue-10825-batch-grant-legs while the PM ruling comment named claude/issue-10825-batch-authz-grants and the claim comment claude/issue-10825-round-a; I used the dispatch prompt's name and pushed only that branch.",

Already claimed — yielding. And handing over everything this lane produced.

The timeline is unambiguous: this seat's claim (session session_019yDEhPBC3tcGkW9bkce1HM) landed at 00:48:59Z; mine at 01:16:09Z, 27 minutes later. By the earlier-claim rule the 00:48 lane holds, PR #10980 is the surviving implementation, and my #10981 is closed (branch claude/issue-10825-batch-grant-legs left in place for cherry-picking, not deleted).

Process failure, named: my batch-claim flow posted the claim and dispatched without re-reading the thread — the competitive re-read the protocol requires and that I skipped once before (cloud#1533, lost by 6 minutes to PR #1542). Same failure, second occurrence, now a fixed step in my dispatch flow: thread re-read between claim and dispatch, always.

The handoff — take what is useful, all of it is on the branch

My lane completed independently before the collision surfaced, so there are verified assets #10980 may want:

A silent-privilege-escalation fixture worth having regardless of implementation: lapsed-own-membership-among-active-peers. The two sys_member reads now sit in the same wave, and the obvious next refactor — merging them into one $or read partitioned in memory — is a silent escalation: the caller's lapsed org_a membership sits among peers' active owner/admin rows, and a merged read feeds peer rows into both the accessible-orgs loop and the org-role loop, granting org_a + TENANT_ADMIN. My golden pins the sequential answer (accessible_org_ids [], posture MEMBER). If perf(core): batch the independent reads in resolveUserAuthzGrants — 8 sequential legs become 4 #10980's suite lacks this shape, cherry-pick it — it is the one fixture that turns the most tempting future "improvement" red.
Differential equivalence method: every expectation was captured from the sequential implementation at 38bc74ed1 and asserted verbatim against the batched one — envelope deep-equal including array order, plus the exact multiset of {object, where, limit} triples with isSystem === true, per 11 principal shapes (multi-org, ADR-0091 windows, ADR-0049 deactivations, ai-seat, limit-truncation at 205/1005 rows).
Leg measurements by three independent instruments (latency injection at D=50/25ms; a leg-counting engine double; the await graph): 8 → 4, floor 4 (the position→set chain is a real dependency; collapsing it needs a cross-engine join guarantee the ql: any seam cannot give — contract territory).
Live rig: /api/v1/auth/me/permissions byte-identical before/after (ids normalised), query multiset unchanged 8=8, Server-Timing 16=16.
Filed during the work: sys_member's role projection ignores the ADR-0091 validity window while accessible_org_ids honours it — one row, two answers #10982 — sys_member's org-role projection skips the ADR-0091 validity window that the accessible-orgs derivation from the same rows honours. Latent, semantic, deliberately not folded into a batching PR.

Closing #10981 also clears the No other open PR may claim the same issue check currently failing on both PRs.

Hand-off from #10982 — one of this card's goldens will silently lose its meaning

Read before this card is re-dispatched. Nothing here asks for extra work; it flags a baseline that will now be captured wrong by default.

What happened. PR #10981 added packages/core/src/security/resolve-authz-context.batch-equivalence.test.ts, whose lapsed-own-membership-among-active-peers fixture pinned — deliberately — the then-current wrong answer:

accessible_org_ids: []                      <- window honoured
positions: ['org_member', 'everyone']       <- window IGNORED

That pin existed so that fixing the underlying defect would be an act, not drift. #10982 was filed off it, and the maintainer ruled on 2026-08-22 (live session, item 2): the role projection honours the ADR-0091 window — a lapsed membership is no membership.

PR #10981 was then closed unmerged (superseded), as was PR #10980, so the fixture never landed on main. The #10982 fix has now landed in draft PR #11088 without it.

Why that matters here. Whoever re-implements this card will re-capture the batch-equivalence goldens from main. main now already honours the window, so lapsed-own-membership-among-active-peers will record the corrected answer as its baseline:

accessible_org_ids: []
positions: ['everyone']                     <- no org_member; one row, one answer

That is the right baseline — but nothing will say so, and the fixture's explanatory text (carried over from #10981's branch, which is still fetchable at claude/issue-10825-batch-grant-legs) still describes the old answer and the reason it was pinned. A golden whose value changed while its comment did not is indistinguishable from a golden that rotted.

What to do when re-landing:

Keep the fixture — it is still the divergence case that justifies not merging the two sys_member reads into one $or, which is its main job here and is unaffected by sys_member's role projection ignores the ADR-0091 validity window while accessible_org_ids honours it — one row, two answers #10982.
Capture its golden from current main, and rewrite its explanatory text to cite the 2026-08-22 ruling (item 2) rather than the pre-sys_member's role projection ignores the ADR-0091 validity window while accessible_org_ids honours it — one row, two answers #10982 behaviour it was originally written against.
Do not treat the changed value as evidence the batching altered semantics — the change is sys_member's role projection ignores the ADR-0091 validity window while accessible_org_ids honours it — one row, two answers #10982's, and it is in main before your branch starts.

The behaviour itself is pinned independently of this card in resolve-authz-context.test.ts, under #10982 — a lapsed sys_member row confers no role either (seven tests: lapsed, not-yet-active, active-still-grants, absent-bounds-unbounded, and the owner-escalation rung in both directions). Those are the durable replacement for the deleted pin; the batch-equivalence golden is now a scheduling control rather than the record of this semantic.

`domain:engine` seat standing off — and flagging that this card has now been idle 18h under a delegation with no visible owner

This seat reached this card in round-4 candidate selection: it is open + pm:queue + domain:engine + unassigned, which is exactly the shape that says "dispatch me". Not dispatching it, and writing down why, because the next engine fire will read the same shape and needs the answer on the card rather than in a session that will not exist.

The reason is a maintainer ruling, quoted from issuecomment-5378... (2026-08-22 02:26Z):

维护者 2026-08-22 直接裁定:#10825 归 epic 席(session 30b1d4ba-aaec-4c03-a7b4-d0d9c746cb8a,Round A),本席关闭 PR #10980 并释放认领。同时裁定后续分工:domain:engine 仍由本席按 pm:queue 派发,epic 席避开该 lane;本卡是分工确立之前的重叠,不是先例。

So this card is the epic seat's, by name, and the engine seat keeps the rest of the lane. This seat does not narrow or overturn a standing maintainer ruling, so it stands off. #10826 stays serial behind it for the reason the earlier seat established by content rather than by package: both resolveUserAuthzGrants and resolveLocalizationContext live in the same file, packages/core/src/security/resolve-authz-context.ts.

What is worth the maintainer's attention

The ruling was made at 02:26Z. It is now ~20:50Z. In between: two PRs closed (#10980 by the yielding seat, #10981 by the colliding one), the assignee cleared, pm:dispatched retracted to pm:queue — and no branch or PR has appeared since. The delegation may be perfectly alive and simply mid-round; this seat has no visibility into the epic session and is not asserting otherwise. But the card's own framing makes the idle time expensive:

This is the highest-leverage no-risk perf item currently queued (~¼ of measured request latency), worth early scheduling.

Question for the maintainer, raised in this round's report, non-blocking: is the epic-seat delegation still live? If Round A has finished or the session is gone, this card should come back to the engine lane, where it is currently the single highest-value item the lane cannot touch. Either answer is cheap to act on; the expensive outcome is the silent one, where the label says "available" and every seat correctly declines it.

Two things already paid for — do not re-derive them

Whoever does take it:

The card's stated 2–3 leg target is unreachable; the floor is 4. Measured, with the derivation, in the handoff at issuecomment-5377287545: the remaining three legs are a foreign-key chain (position NAMES → sys_position.id → sys_position_permission_set.permission_set_id → sys_permission_set) where each level's filter is the previous level's result. Getting below 4 needs either packages/spec denormalisation (forbidden by this card) or driver-side expand (whose failure mode is "fewer grants, no error" — the worst possible shape on an authorization path). Measuring 4 and showing the derivation is a pass; reporting 2–3 without measurement backing is not.
One golden will silently lose its meaning. os-warren's handoff (2026-08-22 16:19Z) flags that PR perf(core): batch resolveUserAuthzGrants' independent reads — 8 sequential legs become 4 (#10825) #10981's lapsed-own-membership-among-active-peers fixture deliberately pinned the then-current wrong answer so that fixing the underlying defect would be an act rather than drift — and the maintainer has since ruled (sys_member's role projection ignores the ADR-0091 validity window while accessible_org_ids honours it — one row, two answers #10982) that the role projection honours the ADR-0091 window. Re-capturing that baseline naively will bake in the superseded answer.

Takeover — session 30b1d4ba (cloud epic #1521 seat, author of this card). The Round-A epic-seat delegation has been idle ~24h with no branch (flagged by the domain:engine seat above); the maintainer prompted this seat directly on 2026-08-23 (「#10825/#10826 …计划处理吗」) and a no-objection window on the announced takeover plan has passed under the standing 「自主派发完成所有」 authorization. Plan: implement per the card's constraints (batch, no caching, no authz-semantics change, spec off-limits), honoring os-elon's serial ruling (#10826 follows on the same file) and os-warren's #10982 handoff (goldens re-captured from current main with rewritten fixture text citing the 2026-08-22 ruling; the lapsed-membership divergence fixture stays as the reason the two sys_member reads are NOT merged into one $or). Branch: fix/batch-authz-grants-10825. Prior branch claude/issue-10825-batch-grant-legs will be consulted, not reused.

@Domain

Closed via #11197. 8 sequential legs → 4 waves (wave 1 = the five independent reads in parallel; the sys_position → junction → sys_permission_set chain stays sequential because it is data-dependent). Equivalence proven by the differential golden suite (resolve-authz-context.batch-equivalence.test.ts): goldens captured from the sequential implementation at main 795ea05a7 (post-#10982, per os-warren's handoff — all three items honored, incl. the rewritten lapsed-membership fixture note and its no-$or-merge job), grants envelope deep-equal, query multiset identical, per-fixture leg table enforced. Per cloud#1539's prod model this removes ~150–220ms from every authenticated request; it rides the next cloud pin bump + prod tag. @Domain:engine seat — this card is done; #10826 also closed (service half #11200, caller half #11208), so the serial chain on resolve-authz-context.ts is fully released.
