target:v18. It takes #5930's grade and train (ruling5902355785: 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

"summary": "Group 1 delivers two of its three faces in draft PR #20895 (Part of #20822, head 94616a9). 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. The route for F3 is open_questions[0].",

"question": "F3 (driver-memory query path, 4 whole-day sites) cannot be deleted without moving answers. Which route? Measured moves: (a) production direct caller DatabaseLoader.queryHistory({until}) in driver mode (setDatabaseDriver; recorded_at is Field.datetime in SysMetadataHistoryObject): until = today goes from 2 rows to 0, and since = until = today from 2 to 0. 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). Declared datetime and date columns are unchanged. (c) 43 direct-call tests in the face's own suites.",
"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. Answersopen_questions[0]ofos-dev-report5915148713. The seat answers in-seat. ⛔ Not a re-ruling: every line below is read offdocs/adr/0053-date-and-datetime-semantics.mdD-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/metadataDatabaseLoader.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
SqlDriveranswers: 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
declaredDatetimeLoweringreads "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.
- (b)'s text and undeclared columns on a registered object converge on what
- So F3 lands as group 1b, one PR in three ordered commits:
DatabaseLoader.queryHistory(driver mode) lowers itswherewithlowerFilterConditionand anisDatetimeColumnread from the history schema it already syncs.- The engine seam applies the rewrite type-blind for an object with no field map (item 7).
- F3's four sites are deleted. Its direct-call tests are routed through
lowerFilterConditionwith a declared-datetime reader, and (b) is declared in the changeset.
Group 2 (driver-sqlF1) 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

document-not. - The one matcher-vs-live divergence (
$existsnon-boolean) is pinned on the live answer and filed as [finding]$existswith 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$exists: z.boolean(), and its$nulltwin is refused #20897.
- F3, stopped and routed: deleting its four sites moves answers, measured on a production direct caller (
DatabaseLoader.queryHistoryin 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.

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:engineexecution 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) putlowerFilterConditionin@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).
