#5930 step 4 (domain:engine): the engine-fed faces delete their hand-copied filter meaning (driver-sql, turso remote, memory query, mongodb, formula, having); the memory reference matcher retires (D6)

Filing gate: ③ a maintainer-directed task, and a ④ child of #5930. The maintainer's words, verbatim: 「5930 v18 启动」. They rule the order of work in ruling 5902355785 on #5930: "(4) per-face deletions, one card per lane, queued as each seam lands, ⛔ no open tail".

Reader: the domain:engine execution seat 1 (session_01DEvba2nBuD4tWzfq8r8NFY, os-support-ai), which claims it once it is queued. It filed this card at the fire after step 2 landed, as that landing record said. ⛔ Filed bare: routing and grading belong to triage. ⛔ Not a claim.

Why now

Step 2 (#5930, PR #20794, cfa931535) put lowerFilterCondition in @objectstack/spec/data. It runs once at every engine filter position, after the doors and token resolution, and at the RLS compile seam. The engine-fed faces now receive the lowered filter. Each still carries its own copy of the meaning the lowering already applied, "until its deletion card" (landing record on #5930). This is this lane's deletion card.

Not this card:

the memory cube face (F5) and the analytics faces (F9, F10, F11) get their seam in step 3 (#5930 step 3: the shared filter lowering at the analytics seams (the analytics where / preview door, the read scope) and the memory cube face's door, with the F5 / F11 output vocabulary #20810), and their deletion cards follow it;
the typed tree (T2) waits for the measurement the ruling names.

Scope (from the design's census, `docs/design/predicate-compilation-convergence.md` §S5; re-measure first)

Face	Deleted	Suites that hold it
F1 `driver-sql`	the NULL-polarity quartet (67 lines), `assertDefinedComparands`, the `calendarDay*Rewrite` calls (5 sites)	`FILTER_LOGIC`, `FILTER_TEXT`, `TEMPORAL`, `FILTER_COMPARAND_TYPE` on SQLite, plus the PostgreSQL / MySQL live matrix
F2 `driver-turso` remote	`toRemoteFilter`'s `$between` / whole-day arms (3 sites), the transport's polarity copy (69 lines)	turso filter-logic (local and remote), local/remote NULL parity
F3 `driver-memory` query	whole-day calls (8 sites)	memory filter-logic, temporal, text
F4 `driver-memory` reference matcher	retired (ruling D6: no production caller)	its 20 importing test files move to the shared suites or to another oracle
F6 `driver-mongodb`	whole-day calls (4 sites)	mongodb filter-logic, text, temporal, comparand-type
F7 `formula`	`lteBound` (2 sites)	matches-filter not-null-safe, or-semantics, temporal
F8 objectql `having`	whole-day calls (4 sites)	having filter-logic, text, temporal

Acceptance, per face:

Direct callers are measured first (review 5903065983, open question 2: "one grep and one probe per step-4 card, no gate"). A caller that reaches the face without passing a seam, such as F7's explain engine or a direct driver call, is named with its answer before and after.
- Under ruling D4 (b), such a caller is routed through the seam: "drivers receive the seams' lowered input; no permanent local guards on faces that bypass a seam".
- If routing it changes an answer, that face stops and is reported.
The face's existing suites stay green before and after the deletion, with an ablation (design §S5).
⛔ No open tail: the card closes when every face above is deleted or reported. It may land as several PRs (one per face or per group, Part of #N until the last).

Recorded gaps (from the ruling): a live remote Turso server and a real mongod were not measured by the design.

Triage: first grade — `tech-debt` · `priority:p2` · `domain:engine` · `area:api` · `target:v18` · `pm:queue`. #5930 step 4 for the engine lane, as ruled

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-30T10:02Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: every face in the table is an engine-lane surface (driver-sql, driver-turso, driver-memory, driver-mongodb, formula, objectql having) ⇒ domain:engine, the lane that holds #5930.

Why p2, target:v18. It takes #5930's grade and train (ruling 5902355785: step 4, "per-face deletions, one card per lane, queued as each seam lands"). Step 2's seam landed (PR #20794, cfa931535), so this lane's deletions are queued now.

Direction. As the card states:

measure direct callers first;
each deletion with an ablation;
⛔ no open tail.

One addition. F4, the memory reference matcher's retirement, moves 20 importing test files onto the shared suites or another oracle. That move must keep each test's assertion, ⛔ not delete it. The report lists each file, and where its assertion now lives.

Serial. F5 and the analytics faces are #20810's (step 3), and their deletions follow it. Nothing here waits on #20810: the driver-memory files touched here (the query path) are not memory-analytics.ts.

Scope note from `domain:engine`: F5 joins this card now that step 3 has landed, and every face names its typed column reader

domain:engine#1 · session_01DEvba2nBuD4tWzfq8r8NFY · 2026-09-30T14:50Z. ⛔ Not a re-ruling: the ruling's "one card per lane, ⛔ no open tail" places it here.

F5 joins. F5 is the driver-memory cube face (MemoryAnalyticsService normalizeFilters), an engine-lane surface. Step 3 (#5930 step 3: the shared filter lowering at the analytics seams (the analytics where / preview door, the read scope) and the memory cube face's door, with the F5 / F11 output vocabulary #20810, PR feat(service-analytics,driver-memory): the shared filter lowering at the analytics seams and the cube face's new door (#5930 step 3) #20857, 793fb839) gave it its seam and doors. Triage's serial clause ("F5 … deletions follow it") is now met, so its whole-day copies (5 sites in the design's census) are deleted here with the rest of driver-memory.
The typed-reader condition comes from the services seat's pointer 5912380805 on [finding] 仓内存在 5 个独立的过滤器→谓词编译器,每次语义裁决成本 ×5 —— 值得立「谓词编译收敛」调查程序(#5298 成本清单副产品) #5930. When a face's own whole-day copy goes, that face needs a typed column reader, or the path loses the whole-day bound. So each face this card deletes from names its typed reader, or states that it has no datetime column to bound.
Delivery. This card lands in groups, each PR Part of #20822, until the last closes it:
1. driver-memory: F3 query path, F4 reference matcher retired (triage: its 20 importing test files keep every assertion), and F5 cube face;

3. driver-mongodb (F6), formula (F7) and objectql having (F8).

Stop on breach and explain in the report.

⛔ Direct callers are measured first (review 5903065983). A caller that reaches a face without the seam is named with its answer before and after, and is routed through the seam (ruling D4 (b)), ⛔ never kept on a local guard.

Step 2's seam (cfa931535) and step 3's seam (793fb839) are both on main.
Clause-②: no: each face already receives the lowered filter, so deleting its copy changes no answer on a seamed path. A direct caller whose answer moves is a finding to report, not an accept-set change to ship silently.

F5: the cube face's filter copy of the whole-day bound (lteUpperBound, 2 call sites) and the storageForm plumbing it needed are deleted. Its door already lowers every where type-blind, so each deleted site ablated on its own at 9905e61 kept 1490/1490 green. The dateRange window arm (3 sites) is kept: it is ADR-0053 D-D1 item 8 and never meets the lowering. F4: memory-matcher.ts is retired (ruling D6). match() had no production caller and no export (the dist export list is the same 33 names), getValueByPath moved into memory-driver.ts, and all 21 importing test files keep their assertions on the live path, the shared gate or the spec predicate the matcher evaluated. F3 is STOPPED and reported (card: "If routing it changes an answer, that face stops and is reported"). Deleting its four sites moves answers. On a production direct caller: @objectstack/metadata DatabaseLoader.queryHistory({until: today}) in driver mode goes from 2 rows to 0. On engine-seamed reads of columns the engine seam does not read as datetime: a text column, an undeclared column and an unregistered object each narrow, e.g. $lte a bare day goes from r1,r2,r3 to r1 or r1,r2. And 43 of the face's own direct-call tests go red. The card premise holds for F4/F5. The claim's Clause-② rationale for F3 ("changes no answer on a seamed path") and dispatch H2 are falsified for everything except declared datetime and date columns.

SqlDriver keeps this today only through its own F1 copy, so group 2 meets the same caller. (b) Engine-seamed reads the seam does not type as datetime, each converging on what SqlDriver already answers: a declared text column holding ISO text ($lte day r1,r2,r3 to r1,r2; $lte 9999-12-31 r1..r4 to r1..r3), a column not declared on a registered object (r1,r2,r3 to r1) and an unregistered object (r1,r2,r3 to r1).

"options": [
"A. Delete F3 now as ruled (D4 (b)): accept (a) and (b), route the 43 tests through lowerFilterCondition with a declared-datetime reader, and state the narrowing in the changeset. Business need: (a) is a real published API (the REST meta history door reaches queryHistory), but driver mode has no in-repo production composition (grep: no setDatabaseDriver caller), so today it reaches an embedder only. Long-term: the ruled end state, with no copy left. Anti-AI-error: ships a silent narrowing of until=YYYY-MM-DD, which an AI writes naturally, so the wrong answer is invisible. Startup focus: cheapest now (one round).",
"B. Route first, then delete: a small metadata-lane change makes DatabaseLoader.queryHistory (driver mode) lower its where with lowerFilterCondition and an isDatetimeColumn read from the history schema it already syncs. F3 is then deleted in its own round, with (b) declared in the changeset as ADR-0053 D-D1 item 7's scope (SqlDriver answers it so today). Business need: keeps the real until door whole-day on every driver, and unblocks group 2 (F1), which meets the same caller. Long-term: contract-first, the caller becomes a seam and no face keeps a guard (D4 (b), the #7872 pattern). Anti-AI-error: the bare day an author writes keeps meaning the whole day. Startup focus: one extra small card, no gate, no new surface.",
"C. Keep F3's type-blind copy permanently for the columns the seam does not type. Business need: no answer moves. Long-term: contradicts D4 (b) (no permanent local guards), and two meanings stay in-package. Anti-AI-error: none gained; the memory double keeps answering text columns differently from SqlDriver. Startup focus: zero cost now, a permanent copy later."

"recommendation": "B. It is the only option that does not ship a silent narrowing on a real door (axis 3), it fixes the caller rather than keeping a face copy (axis 2, D4 (b)), and it costs one small card that group 2 needs anyway (axis 4). The (b) moves are already the answer ADR-0053 D-D1 item 7 and SqlDriver give, so they are declared rather than prevented. One sub-decision stays with the maintainer if wanted: whether an unregistered object read through the engine should keep a whole-day bound. The step-2 seam deliberately reads no field map as no datetime, and making it type-blind would widen SqlDriver's answers too, so the recommendation is to leave it."

Seat answer — #20822 group 1's open question (F3, PR #20895): B, route the caller first, from ADR-0053 D-D1 as amended; open to veto

domain:engine#1 · session_01DEvba2nBuD4tWzfq8r8NFY · 2026-09-30T16:15Z. Answers open_questions[0] of os-dev-report 5915148713. The seat answers in-seat. ⛔ Not a re-ruling: every line below is read off docs/adr/0053-date-and-datetime-semantics.md D-D1 (the Tier H amendment the maintainer approved).

Item 5 (verbatim): "No face keeps a permanent copy for a caller that reaches it without passing a seam … once that face's copy is deleted, such a caller gets the comparison it wrote." So C (keep F3's copy) is out.
Item 10 records exactly this as open: "whether an in-repo direct driver caller … carries a bare-day upper bound that a deleted copy would have widened". The dev measured one: @objectstack/metadata DatabaseLoader.queryHistory({ until }) in driver mode (until = today goes from 2 rows to 0).
- Item 5's remedy is to make that caller a seam, not to keep a copy. B does that, and A would ship a silent narrowing on a published door.
Item 7 (verbatim): "A seam that can read the declared field type rewrites that column only … A seam that cannot applies the rewrite type-blind."
- (b)'s text and undeclared columns on a registered object converge on what SqlDriver answers: item 7's scope. Declare it in the changeset; it is not a decision.
- An unregistered object read through the engine is a seam that cannot read declared types. Item 7 says type-blind there. Step 2's declaredDatetimeLowering reads "no field map" as "no datetime column", which held only while each face kept its copy. That half of the sub-decision is answered by item 7: the engine seam applies the rewrite type-blind when it has no field map.
So F3 lands as group 1b, one PR in three ordered commits:
1. DatabaseLoader.queryHistory (driver mode) lowers its where with lowerFilterCondition and an isDatetimeColumn read from the history schema it already syncs.
2. The engine seam applies the rewrite type-blind for an object with no field map (item 7).
3. F3's four sites are deleted. Its direct-call tests are routed through lowerFilterCondition with a declared-datetime reader, and (b) is declared in the changeset.
  Group 2 (driver-sql F1) meets the same caller, and commit 1 serves it too.
This PR (refactor(driver-memory): retire the reference matcher and the cube face's own whole-day bound (#5930 step 4, group 1: F4 + F5; F3 stopped) #20895) lands as is: F4 retired, F5 deleted. The $exists non-boolean finding the dev measured is filed separately.

ACCEPT — PR #20895 @ `94616a955` (#20822 group 1: F4 and F5; F3 routed to group 1b)

domain:engine#1 · session_01DEvba2nBuD4tWzfq8r8NFY · 2026-09-30T16:42Z. The seat is the reviewer of record. Everything below was read on GitHub and on origin/main, not taken from the report.

Shape: the first line is Part of #20822, then Clause-②: no. The changeset is @objectstack/driver-memory patch. The PR assignee is os-support-ai. 26 files, +865/-1642 (net −777); not governed.
F5, the cube face: its filter copy of the whole-day bound is deleted (lteUpperBound, 2 sites, and the storageForm plumbing it needed).
- Each site ablated alone kept 1490/1490 green. The control ablation, removing the step-3 door's lowerFilterCondition, turned 14 red, so the door holds the bound.
- Its typed reader: none by design. The door lowers type-blind, a superset of datetime, which is ADR-0053 D-D1 item 7.
- The dateRange window arm (item 8) is kept.
F4, the reference matcher: retired (ruling D6). match() had no production caller and no export; the dist export list is unchanged at 33 names.
- All 21 importing test files keep their assertions on the live path, the shared gate, or the spec predicate the matcher evaluated.
- The 77-it drop is 62 duplicate per-case its, still asserted by case name, plus a fold into document-not.
- The one matcher-vs-live divergence ($exists non-boolean) is pinned on the live answer and filed as [finding] $exists with a non-boolean comparand ("yes", 1) is accepted at every door and inverted on driver-memory: it returns the rows with NO value; the spec declares $exists: z.boolean(), and its $null twin is refused #20897.
F3, stopped and routed: deleting its four sites moves answers, measured on a production direct caller (DatabaseLoader.queryHistory in driver mode) and on columns the engine seam does not type.
- The seat answered B from ADR-0053 D-D1 items 5, 7 and 10 (5915193659). F3 lands as group 1b: route that caller through the lowering, make the engine seam type-blind when it has no field map (item 7), then delete.
Contract review: at-tier record 5915388982 on this head, PASS (read-only, Local-runs: none).
Escalated by the review, carried here: comments outside driver-memory still name the retired matcher:
- spec filter-logic-conformance.ts:15, which ships in dist .d.ts;
- formula, service-analytics and service-storage test docblocks;
- plugin-security claim-seed-ownership.ts:91;
- service-analytics objectql-strategy.ts:1929;
- the design doc's F4 row;
- .claude/skills/pm-dispatch/references/compile-surfaces.md (governed).
  carrier: #5930 step 4 (domain:engine): the engine-fed faces delete their hand-copied filter meaning (driver-sql, turso remote, memory query, mongodb, formula, having); the memory reference matcher retires (D6) #20822's last group PR, which corrects each non-governed one (with a spec patch entry for the shipped line) before the card closes, ⛔ no open tail. The governed .claude file stays on the seat post's protocol observation.
Checks on this head: 31 success, 3 skipped, all rostered.

Landing: ready and auto-merge in this act, as two separate relay acts.
